Background
At present, the control of the room temperature and humidity of a transformer substation depends on equipment such as an air conditioner and an exhaust fan, and the specific method is that the air conditioner temperature and the operation time of the exhaust fan are manually set in advance, so that the air conditioner and the exhaust fan can continuously work within a fixed operation time. The operation mode lacking intelligent management and control improves the failure probability of the air conditioner and the exhaust fan. However, for a functional room with few people, especially an unattended transformer substation, when a fault occurs in a certain air conditioner or exhaust fan, the output power of other indoor air conditioners or exhaust fans cannot be found and adjusted in time, which may cause that the equipment in the functional room of the transformer substation works in an abnormal temperature and humidity environment for a long time, resulting in an increased risk of equipment fault. However, for a functional room with only a single air conditioner or exhaust fan, there is a great risk of operation when the functional room fails and is not found in time. Therefore, how to improve the intelligent level of the temperature and humidity control of the transformer substation still remains a technical problem to be solved urgently.

The specific operating logic can be seen in fig. 2.
The background data server 31 controls the air conditioner 14 according to the real-time temperature data and the temperature threshold, that is, when the real-time temperature data exceeds the temperature threshold, the air conditioner 14 is started or the refrigeration effect of the air conditioner 14 is enhanced until the real-time temperature data is recovered to the temperature threshold or below; the background data server 31 controls the exhaust fan 15 according to the real-time relative humidity data and the relative humidity threshold, that is, when the real-time relative humidity data exceeds the relative humidity threshold, the exhaust fan 15 is started or the rotation speed of the exhaust fan 15 is increased until the real-time relative humidity data is recovered to the relative humidity threshold or below.
In a preferred embodiment, if the weather forecast data contains high-temperature early warning information, the background data server 31 sets the temperature threshold T of each functional room of the substation according to the following formula under the condition that the predicted temperature change amplitude of the area where the substation is located is less than or equal to 5 ℃ in the future 3 hours0：

In a preferred embodiment, if the weather forecast data contains strong precipitation warning information, and the precipitation is predicted to be less than or equal to 8mm in the future 1 hour of the area where the transformer substation is located, the background data server 31 sets the relative humidity threshold W of each functional room of the transformer substation according to the following formula0：
Wherein, WeRepresenting real-time relative humidity data, R1Representing the predicted precipitation, R, for 1 hour in the future in weather forecast data24Representing the predicted total amount of precipitation in the weather forecast data for the next 24 hours.

Specifically, W0And WeIn percent, R1And R24In mm.
The specific operation logic of the above embodiment can be seen in fig. 5.
In a preferred embodiment, if the weather forecast data contains strong precipitation warning information, the background data server 31 reminds an operator to manually set the relative humidity threshold of each functional room of the transformer substation through the mobile terminal 32 when the precipitation is predicted to be greater than 8mm in the future 1 hour of the area where the transformer substation is located.
In a preferred embodiment, if the weather forecast data does not contain the high temperature early warning information, the background data server 31 sets the temperature threshold according to a preset temperature default threshold; if the weather forecast data does not contain strong precipitation warning information, the background data server 31 sets the relative humidity threshold according to a preset relative humidity default threshold; and the temperature default threshold and the relative humidity default threshold of each functional room of the transformer substation are set according to the voltage grade, the area, the equipment number and the important grade difference of the functional rooms of the transformer substation.
Specifically, referring to fig. 6, the temperature default threshold and the relative humidity default threshold may be set differently according to different areas, numbers, and importance levels of the functional rooms of the substation with different voltage levels. For example, the battery chamber has a single function and a small area, and an air conditioner and an exhaust fan are usually configured, but the normal operation of the battery has higher requirement on the ambient temperature, so the temperature default threshold value is set by referring to the temperature of the battery, and the temperature can be more accurately controlled and adjusted; the importance of the power distribution room of the main control building is low, only one set of air conditioner and exhaust fan is configured, and the universal temperature default threshold value and the universal relative humidity default threshold value can be set under the condition; the relay protection room and the communication equipment room are various in equipment types, relatively complex in layout and high in importance level, a plurality of air conditioners and exhaust fans are required to be arranged around the room, and each temperature sensor, each humidity sensor, each air conditioner and each exhaust fan form a gridding monitoring area, so that corresponding temperature default threshold values and corresponding relative humidity default threshold values can be set for different grid areas.
In a preferred embodiment, the sensing and adjusting layer 1 further includes a thermocouple sensor 16 disposed in the substation relay protection room device or the high-voltage chamber switch cabinet device, the thermocouple sensor 16 is connected to the network layer 2, and the thermocouple sensor 16 is configured to acquire device internal temperature data of the substation relay protection room device or the high-voltage chamber switch cabinet device; and the background data server 31 controls the corresponding air conditioner according to the real-time temperature data, the temperature data in the equipment and the temperature threshold value.
Through the improvement, the temperature regulation equipment of the functional room of the transformer substation can be monitored and controlled by combining the temperature data inside the key equipment of the transformer substation, the running state of the key equipment is detected, the position of abnormal equipment can be traced through a sensor data source, when a plurality of air conditioners are arranged in the functional room where the abnormal equipment is positioned, the air conditioner closest to the abnormal equipment can be regulated, the efficiency is higher, the energy is saved, and meanwhile, the positioning information is convenient for later-stage maintenance.
The background data server 31 controls the air conditioner 14 according to the internal temperature data of the device and the temperature threshold, that is, when the internal temperature data of the device exceeds the temperature threshold, the air conditioner 14 is started or the refrigeration effect of the air conditioner 14 is enhanced until the internal temperature data of the device is restored to the temperature threshold or below.
In a preferred embodiment, the network layer 2 is a slice network formed by 5G micro base stations arranged in a substation.
Specifically, a slicing network formed by a plurality of 5G micro base stations in the transformer substation can meet the transmission requirements of various services in the substation, and the slicing network has the characteristics of no mutual interference and logic independence between local areas, and is good in stability and high in transmission rate. The connection with the network layer 2 can be realized by arranging a 5G communication module inside the indoor temperature sensor 11, the indoor humidity sensor 12, the noise sensor 13, the air conditioner 14, the exhaust fan 15, the thermocouple sensor 16 and the background data server 31.
In a preferred embodiment, the conditioning equipment fault warning information includes air conditioner fault warning information; and the background data server 31 outputs air conditioner fault warning information when the noise data exceeds a preset noise threshold and the air conditioner 14 is in controlled operation.
Specifically, in the case where the air conditioner 14 is already in a controlled operation, noise in the functional room may come from the radiator of the substation equipment itself; if the air conditioner 14 fails to work, the refrigeration effect is poor, the indoor temperature is not controlled, and the substation equipment can only deal with the failure by increasing the rotating speed of the radiator; therefore, when the noise data exceeds a preset noise threshold and the air conditioner 14 is being controlled to operate, the background data server 31 may output an air conditioner fault warning message; in such an embodiment, the noise sensor should be provided at least in a functional room provided with important equipment, such as a substation relay protection room or a high-voltage room.
In a preferred embodiment, the conditioning apparatus failure warning information includes exhaust fan failure warning information; and the background data server 31 outputs exhaust fan fault warning information when the noise data exceeds a preset noise threshold and the exhaust fan 15 is in controlled operation.
Specifically, when the exhaust fan 15 is being controlled to operate, if the exhaust fan 15 fails, an abnormal sound may be generated, so that the noise data exceeds a preset noise threshold, and when the exhaust fan 15 is being controlled to operate, the background data server 31 may output an exhaust fan failure alarm message.
