The three-layer network refers to a control layer, a network layer and a convergence layer, wherein the temperature sensor operates at the bottom layer in the three-layer network, namely the control layer, and transmits collected temperature data to a dispatching monitoring system working based on the convergence layer.
Wherein at least two temperature sensors to be disposed inside each cabinet may determine a setting rule of the temperature sensors by:
The at least two temperature sensors are mounted at positions remote from the interior heat sink between the cabinets and/or the door and corner positions between the cabinets. Meanwhile, the insertion depth of the at least two temperature sensors is installed according to a preset value, but the insertion depth is not less than 8-10 times of the diameter of the temperature sensor protective sleeve. The temperature sensor is installed in the installation direction as perpendicular as possible, so that deformation of the temperature sensor at high temperature can be prevented, and the situation that the error between the acquired temperature data and the real temperature data between cabinets is larger is avoided. However, in the case of a flow rate, a counter-slope mounting to the flow rate must be employed and is preferably selected at the pipe bend and/or in the middle of the fluid. For temperature sensors subjected to pressure, it is necessary to strictly ensure the sealing performance of the sealing surface.
The temperature data collected by the at least two temperature sensors can be subjected to a rule of determining the temperature of the temperature sensors when the temperature sensors collect the temperatures among the cabinets in the following manner:
And the at least two temperature sensors collect the internal temperature values among all the cabinets according to preset frequency. For example, the preset frequency may be set to 30 seconds/time, 1 minute/time, 2 minutes/time, or the like.
And the temperature data acquired by the at least two temperature sensors are forwarded to a monitoring end through the dispatching monitoring system, and the monitoring end comprises a computer and/or a mobile phone. And the forwarding mode comprises website links, and temperature data among all cabinets can be monitored in real time and globally by clicking the website links. And when the monitoring end displays the temperature data among all the cabinets, the temperature data forwarded by the dispatching monitoring system can be converted into charts and/or graphs of the temperature data acquired among the cabinets at different time according to the temperature data, so that the temperature data is displayed intuitively and clearly, a user can freely select a monitoring and viewing mode, and the user experience is improved.
The temperature data specifically comprises numbers among cabinets, acquisition time of temperature values, acquisition frequency of the temperature values and temperature values inside the cabinets.
Taking the above example as an illustration, assuming that only two temperature sensors are installed inside each cabinet, 1 group of temperature data, such as temperature data between the combined cabinets, comprises 04, acquisition time 2020-10-1:17:55, acquisition interval time 40 seconds/time, and temperature values 78 ℃ and 82 ℃.

The temperature data are collected from the DCS system servers in the network layer among the cabinets in the dispatching monitoring system by the dispatching monitoring system server in the A2, specifically, the temperature data of the DCS system servers in the network layer among the cabinets in different network segments are collected into the same preset network segment through the three-layer switch, so that the collection of the temperature data among all the cabinets is realized, the collected temperature data are retransmitted to the dispatching monitoring system server through the three-layer switch, the temperature data are transmitted from the network layer, namely two layers, to the collection layer, namely three layers, and the temperature data at the moment can be displayed to monitoring personnel through the dispatching monitoring system operation station for monitoring.

Specifically, in the method for monitoring temperature between cabinets according to the embodiment of the present invention, the temperature data transmission process is shown in fig. 2, and examples of the liquid storage cabinet 100, the base oil cabinet 110 and the hazardous waste cabinet 120 are taken.
A10, a temperature sensor between liquid storage cabinets is arranged in the liquid storage cabinet 100, the temperature sensor between the liquid storage cabinets collects temperature data of the liquid storage cabinet 100, then the temperature data of the liquid storage cabinet 100 are transmitted to a distributed control system DCS positioned on a control layer, wherein the specific unit of the temperature data comprises a first DCS system analog input safety grid, a first DCS system analog input clamping piece, a first DCS system communication clamping piece and a first DCS system field controller, and then the first DCS system field controller transmits the temperature data of the liquid storage cabinet 100 to a DCS system server positioned on a network layer;
a20, processing temperature data of a DCS system server at a network layer through the three-layer switch 130 into a preset network segment, and transmitting the temperature data of the liquid storage cabinet 100 to a dispatching monitoring system server of the dispatching monitoring system 140 through the three-layer switch;
A30, collecting temperature data of the liquid cabinet 100 from the dispatching monitoring system server by the MES system data collecting server 150, and storing the temperature data in the MES system data collecting server;
a40, MES system data acquisition server 150 sends temperature data of liquid storage cabinet 100 to monitoring end 170 through VPN server 160 through the Internet.
The temperature data transmission process of the base oil cabinet 110 relates to a temperature sensor, a second DCS system analog input safety grid, a second DCS system analog input card, a second DCS system communication card, a second DCS system field controller, a second DCS system server, a second DCS system operation station, etc. of the base oil cabinet, and the working principle of the temperature data transmission process of the base oil cabinet 100 is the same as that of the liquid storage cabinet 100, and will not be described herein.
The temperature data transmission process of the hazardous waste cabinet 120 relates to a temperature sensor, a second DCS system analog input safety grid, a second DCS system analog input card, a second DCS system communication card, a second DCS system field controller, a second DCS system server, a second DCS system operation station and the like between base oil cabinets, and the working principle of the hazardous waste cabinet 120 is the same as that of the temperature data transmission process of the liquid storage cabinet 100, and is not repeated herein.
Finally, the temperature data in the dispatching and monitoring system server includes the temperature data of the liquid storage cabinet 100, the temperature data of the base oil cabinet 110 and the temperature data of the dangerous waste cabinet 120, and the monitoring end 170 can obtain the temperature data forwarded by the MES system data acquisition server in real time.
Wherein the distributed control system operates in both the network and control layers, but the components operating in the different layers are different. And the dispatching monitoring system can receive and collect all temperature data among the cabinets in real time through the three-layer switch.
As a preferred implementation mode of the temperature data collected by the temperature sensors, the method further comprises the step of taking average value of the temperature data collected by at least two temperature sensors arranged in any one of the cabinets as the temperature data between the cabinets until the temperature data between each cabinet are obtained, so that a user can adjust the temperature between the selected cabinets.
Continuing the description with the same 9 inter-cabinet example, each of the 9 sets of temperature data includes at least 3 temperature values, and the average value obtained by calculating the temperature values between the cabinets after the temperature values between the cabinets are combined in addition to the temperature values between the cabinets acquired by each temperature sensor. If only one or a plurality of sets of temperature data in the 9 sets of temperature data are unsuitable, only the temperature among the one or the plurality of cabinets is adjusted.
Wherein, can confirm the selected among the cabinets through the following way:
The temperature value between the cabinets has a corresponding preset temperature value, when the average value obtained after the temperature value acquired by the temperature sensor in the cabinet is processed is lower than or higher than 20% of the preset temperature value, the temperature value between the cabinets is considered to be abnormal, and the selected cabinet is understood to be the cabinet. For example, if the preset temperature value in the base oil cabinet is 78 ℃, the temperature value between the cabinets is in the range of 62.4 ℃ to 93.6 ℃ and is considered normal, and if the temperature value exceeds 62.4 ℃ or 93.6 ℃, the temperature value between the cabinets is considered abnormal and needs to be adjusted.
The process of adjusting the temperature value between the selected cabinets by the user can be realized by adjusting the temperature of the variable-frequency air conditioner on site by an operator, or can be realized by automatically adjusting the temperature of the variable-frequency air conditioner, so that the temperature of the cabinets is suitable. As long as the variable-frequency air conditioner meets specific conditions, the variable-frequency air conditioner can be connected with a distributed control system based on a network layer of a three-layer network, and the temperature of the cabinet is suitable by adjusting the frequency of the variable-frequency air conditioner.
Specifically, if the temperature between the cabinets is adjusted to be the variable-frequency air conditioner supporting 4-20ma signal input, the variable-frequency air conditioner can be connected with a distributed control system based on a network layer by using a control loop line, so that the automatic temperature adjustment is realized.
