In the following description of the embodiments, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In the prior art, it is common for the associated operator to check the usage of the desiccant in the total radiation meter weekly to determine if the total radiation meter is not leak tight and if the desiccant needs to be replaced. However, the manual detection process in the prior art is complicated, and particularly in areas with difficult conditions, the maintenance labor cost is high.
Aiming at the problems, the abnormality detection method and device for the total radiation meter and the total radiation meter provided by the embodiment of the application are characterized in that the current temperature, the current relative humidity and the last desiccant replacement time in the cavity of the total radiation meter are obtained; determining the current absolute humidity in the total radiometer cavity according to the current temperature and the current relative humidity in the total radiometer cavity; determining an abnormal moment according to the relation between the current absolute humidity and a preset humidity threshold; and determining an abnormal detection result according to a preset desiccant acting time threshold, the last desiccant replacement time and the abnormal moment.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
The embodiment of the application provides an abnormality detection method of a total radiometer, which is used for detecting the abnormal humidity condition of gas in a cavity of the total radiometer in real time. The execution body of the embodiment of the application is an abnormality detection unit in the total radiation table, such as an MCU and other equipment including a processor and a memory and used for abnormality detection.
As shown in fig. 1, a flow chart of a method for detecting an abnormality of a total radiation table according to an embodiment of the present application is shown, where the method includes:
and step 101, acquiring the current temperature, the current relative humidity and the last desiccant replacement time in the cavity of the total radiation meter.
Specifically, a temperature sensor disposed in the total radiometer may be used to collect the current temperature in the cavity of the total radiometer and send the collected current temperature to an anomaly detection unit in the total radiometer. Similarly, a humidity sensor disposed within the total radiometer may be used to collect the current relative humidity within the total radiometer cavity and transmit the collected current relative humidity to an anomaly detection unit in the total radiometer. Because the desiccant needs to be manually replaced, the time for replacing the desiccant last time can be obtained through a manual input mode.
Step 102, determining the current absolute humidity in the total radiometer cavity according to the current temperature and the current relative humidity in the total radiometer cavity.
Specifically, in practical applications, when absolute humidity in the chamber is the same, the relative humidity in the chamber is greatly different due to the difference in ambient temperature, and in this case, if the humidity abnormality of the total radiation meter is determined based on only the value of the relative humidity, an error is easily generated, resulting in lower accuracy of the abnormality detection result. In order to solve the above problems, the abnormality detection method provided by the embodiment of the present application uses the current absolute humidity in the total radiation meter cavity as the basis of abnormality detection, thereby improving the accuracy of the abnormality detection result.
Specifically, in an embodiment, the current temperature in the total radiation table cavity and the current absolute humidity corresponding to the current relative humidity may be determined according to a preset correspondence between the temperature, the relative humidity and the absolute humidity.
It should be explained that the correspondence between the temperature, the relative humidity and the absolute humidity may be obtained by performing a simulation experiment on the total radiation meter, or may be determined according to factory information of the total radiation meter, which is not limited in the embodiment of the present application.
And step 103, determining abnormal time according to the relation between the current absolute humidity and a preset humidity threshold.
The abnormal time is the current time when the total radiation table is abnormal according to the relation between the current absolute humidity and a preset humidity threshold value.
Specifically, in an embodiment, it may be determined whether the current absolute humidity is greater than a preset humidity threshold; when the current absolute humidity is determined to be greater than the humidity threshold, the current time is determined to be an abnormal time.
Accordingly, in one embodiment, when it is determined that the current absolute humidity is not greater than the humidity threshold, return is made to the step of acquiring the current temperature, the current relative humidity, and the last desiccant change time within the total radiometer cavity (step 101).
Specifically, when the current absolute humidity is found to exceed the standard (greater than the humidity threshold), the current total radiation table is determined to be abnormal, and the current moment is determined to be the abnormal moment. Correspondingly, when the current absolute humidity is determined not to exceed the standard (not greater than the humidity threshold), the current total radiation meter is determined to be normal, and then the current temperature and the current relative humidity in the cavity of the total radiation meter are continuously detected in real time.
Step 104, determining an abnormality detection result according to a preset desiccant action time threshold, the last desiccant replacement time and an abnormality time.
Specifically, in an embodiment, the desiccant action time may be determined based on the abnormal time and the last desiccant change time; judging whether the acting time of the drying agent is smaller than a threshold value of the acting time of the drying agent; and when the acting time of the drying agent is smaller than the acting time threshold value of the drying agent, determining that the total radiation meter is in sealing failure, and generating sealing failure alarm information.
Accordingly, in one embodiment, when it is determined that the desiccant on time is not less than the desiccant on time threshold, desiccant failure is determined and desiccant failure alarm information is generated.
In particular, the reasons for the humidity exceeding of the air in the total radiometer cavity are generally two reasons, namely desiccant failure or total radiometer seal failure, for which the analysis can be carried out in particular according to the time of use (desiccant action time) of the desiccant in the current total radiometer.
In particular, the total radiometer seal failure may be determined when the desiccant time is determined to be less than the desiccant time threshold because the humidity in its cavity may increase rapidly when the total radiometer seal fails, thereby causing the desiccant in its cavity to fail in a short period of time.
Similarly, because the service life of the desiccant is limited, if the desiccant cannot be replaced for a long time, the desiccant water absorbing capacity is reduced, and the humidity of the air in the cavity is out of standard, and therefore, if the acting time of the desiccant is not less than the acting time threshold value of the desiccant, the desiccant in the total radiation meter is determined to be invalid.
The service lives of different types of drying agents are different, and the service lives of the same type of drying agents installed in different areas and different environments are also different.
Further, in an embodiment, after the seal failure alarm information or the desiccant failure alarm information is generated, the seal failure alarm information or the desiccant failure alarm information can be reported, and specifically, a mobile phone short message, a prompt tone, a prompt lamp and other reporting modes can be adopted to report so as to remind related operators to replace the desiccant or restore the sealing performance of the total radiation meter.
Exemplary, as shown in fig. 2, a flow chart of an exemplary method for detecting an abnormality of a total radiation table according to an embodiment of the present application is shown. The abnormality detection method shown in fig. 2 is an exemplary embodiment of the abnormality detection method shown in fig. 1, and the implementation principle is the same and will not be described herein.
Specifically, in an embodiment, considering that the total radiating meter is installed outdoors for a long time, the humidity in the cavity is greatly influenced by environmental factors, and in special weather, the humidity increasing rate in a short time is larger than the moisture absorbing rate of the drying agent, so that the total radiating meter has a humidity exceeding phenomenon, but after a period of time, the drying agent fully absorbs the moisture in the cavity, so that the humidity in the cavity of the total radiating meter is reduced below a humidity threshold. Therefore, in order to further improve the accuracy of the abnormality detection result, before determining the current time as the abnormality time, it may be determined whether the duration of the current absolute humidity greater than the humidity threshold reaches the preset duration; and when the duration time that the current absolute humidity is larger than the humidity threshold reaches the preset duration time, determining the current time as the abnormal time.
The preset time period may be set according to actual conditions, specifically may be set according to the performance of the currently used desiccant, and may be set to, for example, 12 hours.
For example, if the preset time period is 12 hours, at 8: the first time of moment 00 confirms that current absolute humidity is greater than humidity threshold (humidity exceeds standard), through carrying out real-time detection to the air humidity in the total radiometer cavity, if at 10: and determining that the current absolute humidity is not greater than a humidity threshold (normal humidity) at the moment 30, and determining that the current total radiation meter is normal if the humidity exceeds the standard for a duration of less than 12 hours. Accordingly, if at 20: and if the total radiation meter is still determined to be in the humidity exceeding state at the moment 00, determining that the current total radiation meter is abnormal, and determining 20: the time 00 is determined as an abnormal time.
In practical applications, the action time threshold of the drying agent is relatively large, and usually, the drying agent is used as a statistical unit of month, such as 6 months. The predetermined time period can thus be almost negligible compared to the predetermined desiccant action time threshold, and therefore the abnormal time can also be determined as 8:00, intermediate value time such as 14:00, can also take 8:00-20: any time between 00.
According to the abnormality detection method for the total radiation meter, the current temperature, the current relative humidity and the last desiccant replacement time in the cavity of the total radiation meter are obtained; determining the current absolute humidity in the total radiometer cavity according to the current temperature and the current relative humidity in the total radiometer cavity; determining an abnormal moment according to the relation between the current absolute humidity and a preset humidity threshold; and determining an abnormal detection result according to a preset desiccant acting time threshold, the last desiccant replacement time and the abnormal moment. According to the abnormality detection method provided by the scheme, the reasons for the abnormality of the total radiation meter can be analyzed according to the time difference between the abnormality time and the last desiccant replacement time and the preset desiccant action time threshold value, the abnormality detection result is determined, the abnormality detection efficiency is improved while the accuracy of the abnormality detection result is improved, and a foundation is laid for guaranteeing the reliability of the total radiation meter.
