Referring to fig. 1, there is shown a schematic configuration of a data transmission system for a distribution box having an automatic fire extinguishing function according to the present invention. This block terminal data transmission system with automatic fire extinguishing function includes:
the data acquisition module 101 is configured to acquire a target temperature sequence and a target smoke concentration sequence corresponding to each preset time in a preset time period of the target distribution box.
In some embodiments, a target temperature sequence and a target smoke concentration sequence corresponding to each preset time of the target distribution box in a preset time period may be obtained.
The target distribution box can be a distribution box for fire detection. The preset time period may be a preset time period. For example, the duration corresponding to the preset time period may be 6 seconds. The preset time period may be 2023, 04, 18, 10, 18 minutes, 20 seconds to 2023, 04, 18, 10, 18 minutes, 26 seconds. The preset time may be a preset time. For example, the duration between every two adjacent preset moments within the preset time period may be 1 second. The preset time may be 2023, 04, 18, 10, 18 minutes, 22 seconds. The last preset time in the preset time period may be the current time, that is, the end time of the preset time period may be the current time. The target temperature may be an internal temperature of the target power distribution box normalized. The target smoke concentration may be a normalized smoke concentration within the target electrical box. The smoke concentration and temperature inside the electrical box may be electrical box data. The block terminal data may be data relating to whether a block terminal has a fire. The target temperature sequence corresponding to the preset time may include: target temperatures at each preset history time in a preset history time period corresponding to the preset time. The preset history period may be a preset period. The duration corresponding to the preset history period may be equal to the duration corresponding to the preset period. The preset history time may be a preset time. The time period between two adjacent preset history times may be equal to the time period between two adjacent preset times. The last preset historical time in the preset historical time period corresponding to the preset time can be the preset time, that is, the ending time of the preset historical time period corresponding to the preset time can be the preset time. The target smoke concentration sequence corresponding to the preset time may include: the target smoke concentration at each preset history time in the preset history time period corresponding to the preset time. The target temperature sequence and the target smoke concentration sequence may be sequences ordered according to the acquisition time.
It should be noted that, because the more likely the block terminal will take place the condition of a fire, the more the inside temperature of block terminal tends to be high, and when the block terminal takes place the condition of a fire, often can produce smog to the inside temperature of block terminal is compared in smog concentration, more has timeliness to the judgement of condition of a fire. Therefore, the target temperature sequence and the target smoke concentration sequence corresponding to each preset time of the target distribution box in the preset time period are obtained, the target temperature sequence and the target smoke concentration sequence corresponding to each preset time can be conveniently and comprehensively analyzed later, and accordingly the accuracy of judging the follow-up fire condition can be improved. And secondly, the target temperature and the target smoke concentration are normalized data, so that the problem of different dimensions between the smoke concentration and the temperature in the target distribution box can be eliminated, and the subsequent processing can be facilitated.
As an example, the internal temperature of the target distribution box at each preset history time may be collected by the temperature sensor, and the collected internal temperature may be normalized to obtain the target temperature at each preset history time. Wherein a temperature sensor may be used to collect temperature. The acquisition time of the target temperature at the preset history time may be the preset history time. Then, the smoke concentration inside the target distribution box at each preset historical moment can be collected through a smoke concentration sensor, and the collected smoke concentration is normalized to obtain the target smoke concentration at each preset historical moment. Wherein a smoke concentration sensor may be used to collect smoke concentration. The collection time of the target smoke concentration at the preset history time may be the preset history time.
For example, the duration corresponding to the preset time period may be 3 seconds. The preset time period may be 2023, 04, 18, 10, 18 minutes, 20 seconds to 2023, 04, 18, 10, 18 minutes, 22 seconds. The duration between every two adjacent preset moments in the preset time period may be 1 second. The preset time period may include 3 preset times, which may be 2023, 04, 18, 10, 18 minutes, 20 seconds, 2023, 04, 18, 10, 18 minutes, 21 seconds, and 2023, 04, 18, 10, 18 minutes, 22 seconds, respectively.
The change analysis processing module 102 is configured to perform change analysis processing on the preset time according to the target temperature sequence and the target smoke concentration sequence corresponding to each preset time, so as to obtain a temperature change characteristic and a smoke change characteristic corresponding to the preset time.
In some embodiments, the change analysis processing may be performed on each preset time according to the target temperature sequence and the target smoke concentration sequence corresponding to each preset time, so as to obtain the temperature change characteristic and the smoke change characteristic corresponding to the preset time.
It should be noted that, because the target temperature and the target smoke concentration tend to be relatively stable during normal operation of the target distribution box, for example, the target smoke concentration tends to be stable to be 0, the change analysis processing is performed on the preset time based on the target temperature sequence and the target smoke concentration sequence, so that it is convenient to determine whether the target distribution box is operating normally.
As an example, this step may include the steps of:
the first step, determining the temperature change characteristics corresponding to the preset time according to the target temperature sequence corresponding to the preset time.
For example, the formula corresponding to the temperature change feature corresponding to the preset time may be determined as follows:
wherein,,is the temperature change characteristic corresponding to the ith preset moment in the preset time period. a is a preset coefficient greater than zero, for example, a may be。Is the number of target temperatures in the target temperature sequence corresponding to the i-th preset moment in the preset time period.The target temperature is the kth target temperature in the target temperature sequence corresponding to the ith preset time in the preset time period, namely the target temperature at the kth preset historical time in the preset historical time period corresponding to the ith preset time.The target temperature is the (k-1) target temperature in the target temperature sequence corresponding to the (i) th preset time in the preset time period, namely the target temperature at the (k-1) th preset historical time in the preset historical time period corresponding to the (i) th preset time.Is the acquisition time of the kth target temperature in the target temperature sequence corresponding to the ith preset time in the preset time period, namely the ith preset time And etching the kth preset historical moment in the corresponding preset historical time period.Is the acquisition time of the (k-1) th target temperature in the target temperature sequence corresponding to the (i) th preset time in the preset time period, namely the (k-1) th preset historical time in the preset historical time period corresponding to the (i) th preset time.Is thatIs the absolute value of (c). i is a sequence number of a preset time in a preset time period. k is the sequence number of the target temperature in the target temperature sequence corresponding to the ith preset moment in the preset time period. Since k is the sequence number of the target temperature in the target temperature sequence corresponding to the ith preset time in the preset time period, and the target temperature in the target temperature sequence can be in one-to-one correspondence with the preset historical time in the preset historical time period, k can also be the sequence number of the preset historical time in the preset historical time period corresponding to the ith preset time.
When the following is performedWhen the target temperature is larger, the more unstable the target temperature in the target temperature sequence corresponding to the ith preset moment is often described, and the acquisition time of the target temperature is integrated, so thatThe degree of instability of the target temperature in the target temperature sequence corresponding to the ith preset moment can be represented. Since the target temperature is stable when the target distribution box is in normal operation, whenThe larger the target distribution box is, the more likely the target distribution box is to have a risk of fire at the ith preset moment.
And a second step of determining smoke change characteristics corresponding to the preset moment according to the target smoke concentration sequence corresponding to the preset moment.
For example, the formula for determining the smoke change feature corresponding to the preset time may be:
wherein,,is the smoke change characteristic corresponding to the ith preset moment in the preset time period. a is a preset coefficient greater than zero, for example, a may be。The target smoke concentration is the kth target smoke concentration in the target smoke concentration sequence corresponding to the ith preset time in the preset time period, namely the target smoke concentration at the kth preset historical time in the preset historical time period corresponding to the ith preset time.The target smoke concentration is the (k-1) target smoke concentration in the target smoke concentration sequence corresponding to the (i) th preset time in the preset time period, namely the target smoke concentration at the (k-1) th preset history time in the preset history time period corresponding to the (i) th preset time.Is the acquisition time of the kth target smoke concentration in the target smoke concentration sequence corresponding to the ith preset time in the preset time period, namely the kth preset historical time in the preset historical time period corresponding to the ith preset time.Is the acquisition time of the (k-1) th target smoke concentration in the target smoke concentration sequence corresponding to the (i) th preset time in the preset time period, namely the (k-1) th preset history in the preset history time period corresponding to the (i) th preset timeTime of day.Is thatIs the absolute value of (c). i is a sequence number of a preset time in a preset time period. Since k is the sequence number of the target temperature in the target temperature sequence corresponding to the i-th preset time in the preset time period, k can also be the sequence number of the preset history time in the preset history time period corresponding to the i-th preset time, and the target temperature in the target temperature sequence can be in one-to-one correspondence with the preset history time in the preset history time period, and the target smoke concentration in the target smoke concentration sequence can be in one-to-one correspondence with the preset history time in the preset history time period, so k can also be the sequence number of the target smoke concentration in the target smoke concentration sequence corresponding to the i-th preset time. The number of target smoke concentrations in the sequence of target smoke concentrations may be equal to the number of target temperatures in the sequence of target temperatures, andis the number of target temperatures in the target temperature sequence corresponding to the i-th preset time in the preset time period, thusThe number of the target smoke concentrations in the target smoke concentration sequence corresponding to the i-th preset time in the preset time period can also be set.
When the following is performedWhen the target smoke concentration is larger, the more unstable the target smoke concentration in the target smoke concentration corresponding to the ith preset moment is often described, and the acquisition time of the target smoke concentration is integrated, so thatThe degree of instability of the target smoke concentration in the target smoke concentration sequence corresponding to the ith preset moment can be represented. Because the target smoke concentration tends to be relatively stable when the target distribution box is in normal operation, whenThe larger the target distribution box is, the more likely the target distribution box is to have a risk of fire at the ith preset moment.
The initial determining module 103 is configured to determine an initial fire indicator corresponding to the current time according to the temperature change feature and the smoke change feature corresponding to each preset time in the preset time period, and the reference temperature and the reference smoke concentration acquired in advance.
In some embodiments, the initial ignition index corresponding to the current time may be determined according to the temperature change feature and the smoke change feature corresponding to each preset time in the preset time period, and the reference temperature and the reference smoke concentration acquired in advance.
The reference temperature may be a normalized temperature when the target distribution box is normally used. The reference smoke concentration may be a normalized smoke concentration of the target block terminal when in normal use. For example, the reference smoke concentration may be 0.
It should be noted that, by comprehensively considering the temperature change feature and the smoke change feature, and the reference temperature and the reference smoke concentration obtained in advance, the accuracy of determining the initial ignition index can be improved.
As an example, this step may include the steps of:
the first step, normalizing the difference value between the target temperature and the reference temperature at each preset time acquired in advance to obtain the initial temperature deviation corresponding to the preset time.
The target temperature at the preset time may be a target temperature acquired at the preset time.
And a second step of determining a target temperature deviation corresponding to the current time according to the initial temperature deviation corresponding to each preset time in the preset time period.
The initial temperature deviation corresponding to each preset time in the preset time period may be positively correlated with the target temperature deviation.
Thirdly, normalizing the difference value of the target smoke concentration and the reference smoke concentration at each preset time acquired in advance to obtain an initial smoke deviation corresponding to the preset time.
The target smoke concentration at the preset time may be the target smoke concentration collected at the preset time.
Fourth, determining the target smoke deviation corresponding to the current time according to the initial smoke deviation corresponding to each preset time in the preset time period.
The initial smoke deviation corresponding to each preset time in the preset time period can be positively correlated with the target smoke deviation.
And fifthly, determining a first reference index according to the target temperature deviation and the target smoke deviation.
Wherein the target temperature deviation and the target smoke deviation may both be positively correlated with a first reference index.
For example, the formula for determining that the first reference index corresponds to may be:
wherein,,is the first reference index corresponding to the current moment.Is the target smoke deviation corresponding to the current moment.Is the target temperature deviation corresponding to the current moment. N is the number of preset moments in a preset time period.Is the target temperature at the i-th preset time in the preset time period. x is the reference temperature.Is the target smoke concentration at the i-th preset time in the preset time period. y is the reference smoke concentration. i is a sequence number of a preset time in a preset time period.Can realize the pair ofIs included in the (c) for the normalization.Can realize the pair ofIs included in the (c) for the normalization.Is the initial temperature deviation corresponding to the i-th preset moment in the preset time period.And (3) withAnd shows positive correlation.Is the initial smoke deviation corresponding to the i-th preset moment in the preset time period.And (3) withAnd shows positive correlation.Andare all in contact withAnd shows positive correlation.
When the following is performedThe larger the target temperature at the ith preset time, the higher the target temperature is, and the more likely the target distribution box is at the ith preset time, the risk of fire is. When (when)The larger the target smoke concentration at the ith preset time, the higher the target smoke concentration is, and the more likely the target distribution box is at the ith preset time, the risk of fire is shown. For a pair ofAndnormalization is performed, so that subsequent processing can be facilitated. When (when)The larger the target temperature in the preset time period is, the higher the target temperature in the preset time period is, the more the risk of fire occurrence of the target distribution box in the preset time period is, and therefore the more the risk of fire occurrence of the target distribution box at the current moment is. When (when)The larger the target smoke concentration in the preset time period, the higher the target smoke concentration in the preset time period, the more likely the target distribution box is in the risk of fire in the preset time period, and therefore the more likely the target distribution box is in the risk of fire at the current moment. Thus (2)The larger it is often stated that the more likely the target block terminal is at the present time that there is a risk of a fire.
And sixthly, determining a second reference index corresponding to the current moment according to the temperature change characteristics and the smoke change characteristics corresponding to each preset moment in the preset time period.
For example, according to the temperature change feature and the smoke change feature corresponding to each preset time within the preset time period, determining the second reference index corresponding to the current time may include the following substeps:
and a first sub-step of combining the temperature change characteristic and the smoke change characteristic corresponding to each preset time into characteristic coordinates corresponding to the preset time.
Wherein the feature coordinates may be two-dimensional coordinates.
For example, first, the temperature change feature corresponding to the preset time may be determined as the abscissa included in the feature coordinate corresponding to the preset time. Then, the smoke change feature corresponding to the preset time can be determined as the ordinate included in the feature coordinates corresponding to the preset time.
And a second sub-step, for each adjacent two preset moments in the preset time period, determining the distance between the feature coordinates corresponding to the two preset moments as a feature difference index between the two preset moments.
For example, the euclidean distance between the feature coordinates corresponding to any two adjacent preset moments in the preset time period can be determined as the feature difference index between the two preset moments.
And a third sub-step of determining the second reference index according to the characteristic difference index between each adjacent preset time in the preset time period.
The characteristic difference index between each adjacent preset time in the preset time period may be positively correlated with the second reference index.
For example, the formula for determining the second reference index may be:
wherein w is a second reference index corresponding to the current time. N is the number of preset moments in a preset time period.Is a characteristic difference index between the ith preset time and the (i+1) th preset time in a preset time period, namely the ith preset time and the (i)And i+1 Euclidean distances between the feature coordinates corresponding to the preset moments. i is a sequence number of a preset time in a preset time period.Positively correlated with w.
When the following is performedThe larger the temperature and smoke state corresponding to the i-th preset time are, the more different the temperature and smoke state of the i+1th preset time are, the more possible the target distribution box is between the i-th preset time and the i+1th preset time is, and the risk of fire is indicated. Thus, when w is greater, it is often stated that the target block terminal is more likely to be at risk of fire at the present time.
And seventh, determining an initial ignition index corresponding to the current moment according to the first reference index and the second reference index.
Wherein, the first reference index and the second reference index can be positively correlated with the initial fire index.
For example, the formula corresponding to the initial firing indicator corresponding to the current time may be determined as follows:
wherein Q is an initial firing index corresponding to the current moment. w is a second reference index corresponding to the current time.Is the first reference index corresponding to the current moment. w andare all positively correlated with Q.
It should be noted that, when w is larger, it is often explained that the target distribution box is more likely to have a risk of occurrence of a fire at the present moment. When (when)The larger it is often stated that the more likely the target block terminal is at the present time that there is a risk of a fire. Thus, when Q is greater, it is often stated that the more likely the target block terminal is at the present time that a fire is at risk.
Alternatively, the formula corresponding to the initial fire index corresponding to the current time may be determined as follows:
wherein Q is an initial firing index corresponding to the current moment.Is the integral deviation corresponding to the i-th preset moment in the preset time period.Is the target temperature at the i-th preset time in the preset time period. x is the reference temperature.Is the target smoke concentration at the i-th preset time in the preset time period. y is the reference smoke concentration.Is a characteristic difference index between the i < th > preset time and the (i+1) th preset time in the preset time period. i is a sequence number of a preset time in a preset time period.Can realize the pair ofIs included in the (c) for the normalization.Can realize the pair ofIs included in the (c) for the normalization.
When the following is performedThe larger the target temperature and the target smoke concentration at the ith preset time, the higher the target temperature and the target smoke concentration are, and the more likely the target distribution box is at the ith preset time, the risk of fire is. When (when)The larger the target distribution box, the more likely the target distribution box is between the ith preset time and the (i+1) th preset time to have the risk of fire. Thus, when Q is greater, it is often stated that the more likely the target block terminal is at the present time that a fire is at risk.
The target determining module 104 is configured to determine a target fire indicator corresponding to the current moment according to the initial fire indicator, the temperature change feature and the smoke change feature corresponding to the current moment.
In some embodiments, the target fire indicator corresponding to the current time may be determined according to the initial fire indicator, the temperature change feature corresponding to the current time, and the smoke change feature.
It should be noted that, by comprehensively considering the initial fire index, the temperature change feature and the smoke change feature corresponding to the current moment, the accuracy of determining the target fire index corresponding to the current moment can be improved.
As an example, this step may include the steps of:
first, determining a temperature abnormality index according to the initial ignition index and the temperature change characteristic corresponding to the current moment.
Wherein, the initial ignition index and the temperature change characteristic corresponding to the current moment can be positively correlated with the temperature abnormality index.
And secondly, determining a smoke abnormality index according to the initial ignition index and the smoke change characteristic corresponding to the current moment.
The initial ignition index and the smoke change characteristic corresponding to the current moment can be positively correlated with the smoke abnormality index.
And thirdly, determining the target ignition index according to the temperature abnormality index and the smoke abnormality index.
Wherein, the temperature abnormality index and the smoke abnormality index may both be positively correlated with the target ignition index.
For example, the formula for determining the target firing indicator corresponding to the current time may be:
Wherein vb is a target firing indicator corresponding to the current time. wt is an index of temperature anomaly. Q is the initial fire index corresponding to the current moment. the tem is a temperature change characteristic corresponding to the current time. wf is an indicator of smoke anomalies. fmp is the smoke variation characteristic corresponding to the current moment.Normalization to wt×wf can be achieved. Q and tem are both positively correlated with wt. Q and fmp are both positively correlated with wf. Both wf and wt are positively correlated with vb.
When Q is larger, it is often explained that the target distribution box is more likely to have a risk of fire at the present time. When the tem is larger, it tends to indicate that the target temperature in the period adjacent to the current time is more unstable, and tends to indicate that the target distribution box is more likely to have a risk of fire at the current time. When fmp is greater, it tends to indicate that the target smoke concentration is less stable in the time period adjacent to the current time, and tends to indicate that the target distribution box is more likely to be at risk of fire at the current time. Thus, the larger vb, the more likely the target distribution box is at the present moment at which the risk of fire will occur.
The generating and transmitting module 105 is configured to generate a fire judgment sign corresponding to the current moment according to the target fire index, and transmit the fire judgment sign to the automatic fire extinguishing module.
In some embodiments, a fire judgment mark corresponding to the current moment may be generated according to the target fire index, and the fire judgment mark may be transmitted to the automatic fire extinguishing module.
Wherein the fire judgment flag may be data for characterizing a fire risk condition of the target distribution box. The automatic fire extinguishing module can realize automatic fire extinguishing of the target distribution box.
Based on the target firing indicator, the accuracy of the firing judgment flag generation corresponding to the current time can be improved. And the fire judgment mark is transmitted to the automatic fire extinguishing module, so that the automatic fire extinguishing of the target distribution box can be realized.
As an example, this step may include the steps of:
and a first step of determining the first preset data as a fire judgment mark when the target fire index is greater than or equal to a first preset fire threshold.
The first preset fire threshold may be a preset minimum target fire index when the target distribution box is considered to be required to extinguish a fire. For example, the first preset fire threshold may be 0.7. The first preset data may be preset data. For example, the first preset data may be 1.
And a second step of determining second preset data as a fire judgment mark when the target fire index is smaller than a first preset fire threshold and larger than or equal to a second preset fire threshold.
Wherein the second preset fire threshold may be less than the first preset fire threshold. The second preset fire threshold may be a preset minimum target fire indicator when the target distribution box is considered to have a fire risk. For example, the second preset fire threshold may be 0.5. The first preset data and the second preset data may be different. The second preset data may be preset data. For example, the second preset data may be 0.
And thirdly, when the target fire index is smaller than a second preset fire threshold, determining third preset data as a fire judgment mark.
The first preset data, the second preset data and the third preset data may be different. The third preset data may be preset data. For example, the third preset data may be 2.
And step four, transmitting the fire judgment mark to the automatic fire extinguishing module.
For example, the fire judgment flag may be transmitted to a self-extinguishing module, through which self-extinguishing of the target distribution box may be achieved.
The automatic fire extinguishing module can be used for judging the received fire judgment mark, and when the fire judgment mark is the first preset data, the target distribution box is extinguished through the fire extinguisher. When the fire judgment mark is the second preset data, a fire prompt message can be sent to remind workers that the target distribution box is abnormal, and a fire disaster can occur.
Optionally, when the fire judgment mark is the first preset data, the fire judgment mark is transmitted to the fire extinguishing execution module, and the fire extinguishing execution module can realize automatic fire extinguishing of the target distribution box. The fire-extinguishing execution module is used for extinguishing fire to the target distribution box through the fire extinguisher.
In summary, firstly, when the more likely the block terminal will take place the condition of a fire, the more the inside temperature of block terminal tends to be high, and when the block terminal takes place the condition of a fire, often can produce smog to the inside temperature of block terminal is compared with smog concentration, has more timeliness to the judgement of condition of a fire. Therefore, the target temperature sequence and the target smoke concentration sequence corresponding to each preset time of the target distribution box in the preset time period are obtained, the target temperature sequence and the target smoke concentration sequence corresponding to each preset time can be conveniently and comprehensively analyzed later, and accordingly the accuracy of judging the follow-up fire condition can be improved. Then, because the target temperature and the target smoke concentration tend to be relatively stable when the target distribution box normally works, the change analysis processing is carried out on the preset moment based on the target temperature sequence and the target smoke concentration sequence, so that whether the target distribution box normally works or not can be conveniently judged. Then, the accuracy of the initial ignition index determination can be improved by comprehensively considering the temperature change characteristic and the smoke change characteristic, and the reference temperature and the reference smoke concentration which are acquired in advance. And then, comprehensively considering the initial ignition index, the temperature change characteristic and the smoke change characteristic corresponding to the current moment, and improving the accuracy of determining the target ignition index corresponding to the current moment. Then, based on the target fire index, the accuracy of generating the fire judgment mark corresponding to the current moment can be improved. Finally, the fire judgment mark is transmitted to the automatic fire extinguishing module, so that automatic fire extinguishing of the target distribution box can be realized. Therefore, the invention can detect the fire condition of the target distribution box in real time, comprehensively considers the target temperature sequence and the target smoke concentration sequence, improves the accuracy of fire condition judgment, and reduces the potential safety hazard of the distribution box.
