As shown in fig. 1, the method includes:
and 110, acquiring a real-time humidity value of the temperature and humidity sensor, and judging whether the real-time humidity value exceeds a humidity threshold value by adopting an edge calculation mode.
Wherein, temperature and humidity sensor arranges in the terminal incasement for detect the temperature data and the humidity data of terminal incasement.
Edge computing refers to a way to deploy workloads at the edge, as opposed to traditional centralized general purpose computing. Specifically, edge computation is a distributed operation architecture. Under the structure, the operation of application program, data and service is moved from the central node of the network to the edge node of the network logic for processing. The intelligent temperature and humidity controller realizes customizing a control strategy according to needs or realizing constant value operation through an edge calculation function, coordinates the working processes of a plurality of dehumidification devices and achieves the effects of energy conservation and consumption reduction.
Illustratively, a serial interface in communication with the temperature and humidity sensor is scanned to obtain a real-time humidity value collected by the temperature and humidity sensor. And comparing the real-time humidity value with a humidity threshold value, and determining whether the real-time humidity value exceeds the humidity threshold value according to a comparison result. Specifically, the intelligent temperature and humidity controller obtains real-time temperature values and real-time humidity values of all temperature and humidity sensors in the terminal box through scanning serial interfaces communicated with the temperature and humidity sensors. And judging whether the real-time humidity value exceeds a humidity threshold value. If yes, determining the current dehumidification equipment based on a starting sequence specified by a preset control strategy, and sending a first starting instruction to the current dehumidification equipment; otherwise, continuously judging whether the real-time humidity value exceeds the humidity threshold value after waiting for the set time.

And 120, when the humidity threshold value is exceeded, sequentially starting a plurality of dehumidification devices based on a preset control strategy.
For example, when the humidity threshold value is exceeded, the current dehumidification equipment is determined based on the starting sequence specified by the preset control strategy, and a first starting instruction is sent to the current dehumidification equipment. And determining the humidity change amount according to the real-time humidity value, and calculating the humidity change rate based on the humidity change amount and the humidity adjusting time.

And when judging that the starting conditions of the residual equipment are met based on the working information, starting the residual dehumidifying equipment according to the starting sequence, and detecting the working information of the started dehumidifying equipment. And when the real-time humidity value meets the dehumidification ending condition, sending a stopping instruction to all started dehumidification equipment. Specifically, whether or not the remaining apparatus start-up condition is satisfied may be determined in the following manner: and acquiring the individual working time of the started dehumidifying equipment. And under the condition that the single working time exceeds a set time threshold, if the real-time humidity value is not lower than the humidity threshold, determining that the starting condition of the residual equipment is met.
And step 130, when the real-time humidity value meets the dehumidification ending condition, sending a stopping instruction to all started dehumidification equipment.
In the embodiment of the invention, the running state recorded by the intelligent temperature and humidity controller represents all started dehumidification equipment. For example, if the operation state is the first value, it indicates that the dehumidification device is started.
Illustratively, when detecting that the real-time humidity value is lower than the humidity threshold value, the intelligent temperature and humidity controller reads the operation state of each dehumidification device, determines started dehumidification devices based on the operation state, and sends a stop instruction to all the started dehumidification devices.
The humidity control method of the present embodiment will be described by taking 3 sets of dehumidification devices as an example. Fig. 2 is a schematic communication diagram of an intelligent temperature and humidity control and dehumidification device according to an embodiment of the present invention. When the intelligent temperature and humidity controller 210 arranged in the terminal box in the monitoring equipment area detects that the real-time humidity value is higher than the humidity threshold value, the occurrence of humidity out-of-limit is determined according to an edge calculation mode. The method comprises the steps of determining that the dehumidifier 220 is started first based on a starting sequence specified by a preset control strategy, and sending a first starting instruction to the dehumidifier 220. After the dehumidifier 220 is put into operation and started, the humidity variation is determined according to the real-time humidity value in the terminal box. And acquiring the working information of the dehumidifier 220, and determining the input operation time of the dehumidifier based on the working information. And calculating the humidity change rate based on the humidity change amount and the input operation time of the dehumidifier. If the humidity change rate is not less than the set slope value, the dehumidifier 220 is maintained to operate alone. It should be noted that, under the condition that the humidity change rate is not lower than the set slope value, if the input operation time of the dehumidifier exceeds the preset time threshold (i.e. the single operation time threshold) and the current real-time humidity value does not reach the humidity threshold, the second start instruction is sent to the first heating plate 230. And when the real-time humidity value meets the dehumidification ending condition, sending a stopping instruction to the dehumidifier 220. Wherein, the dehumidification end condition may be that the real-time humidity value is smaller than the humidity threshold value. Optionally, the dehumidification ending condition may also be that the real-time humidity value is smaller than the difference between the humidity threshold value and the humidity return difference value.
If the humidity change rate is lower than the set slope value, a second start command is sent to the first heating plate 230. At the stage where the dehumidifier 220 and the first heating plate 230 are operated together, the humidity change rate is calculated based on the humidity change rate and the common operation time. If the humidity change rate is not less than the set slope value, the dehumidifier 220 and the first heating plate 230 are maintained to work together. It should be noted that, under the condition that the humidity change rate is not lower than the set slope value, if the commissioning time of the first heating plate has exceeded the preset time threshold (i.e., the single working time threshold), and the current real-time humidity value has not reached the humidity threshold or lower, the third start instruction is sent to the second heating plate 240. When the real-time humidity value satisfies the dehumidification end condition, a stop command is sent to the dehumidifier 220 and the first heating plate 230.
If the humidity change rate is still lower than the set slope value, a third start command is sent to the second heating plate 240. And then, comparing the real-time humidity value with a humidity threshold value, and sending a stop instruction to all started dehumidification equipment when the real-time humidity value is lower than the humidity threshold value.
According to the technical scheme, the humidity out-of-limit is judged based on the real-time humidity value by acquiring the real-time humidity value of the temperature and humidity sensor in an edge calculation mode, and when the humidity out-of-limit occurs, a plurality of dehumidification devices are sequentially started based on a preset control strategy; and when the real-time humidity value meets the dehumidification ending condition, sending a stopping instruction to all started dehumidification equipment. According to the embodiment, the control strategy is customized as required through an edge calculation mode, the plurality of dehumidification devices are coordinately controlled to work through the control strategy, so that the humidity microenvironment in the terminal box can be intelligently adjusted, the problem that the abnormal microenvironment in the terminal box can not be timely adjusted in the related art is solved, and the intelligent level of power grid equipment and state detection is improved.
On the basis of the technical scheme, after the plurality of dehumidification devices are sequentially started based on the preset control strategy, the method can further comprise the step of outputting failure early warning information of the dehumidification devices when the started dehumidification devices are judged to have failures based on the humidity change rate. Specifically, after one piece of dehumidification equipment is started, if the humidity change rate is smaller than a preset humidity change threshold value, it is determined that the dehumidification equipment has a fault. Optionally, after the plurality of initial devices are started, if the humidity change rate is smaller than a preset humidity change threshold value, determining the dehumidifying device with the fault through an elimination method. For example, the dehumidification devices can be controlled to stop operating one by one, and whether the humidity change rate is not less than the preset humidity change threshold value in the operation process of the rest of the dehumidification devices is detected, so as to determine whether the stopped dehumidification devices are in failure. It should be noted that, when different numbers of dehumidification devices operate, the humidity change threshold values are different, and the humidity change threshold values may be configured manually according to actual operating conditions. The advantage that sets up like this lies in can judging the dehumidification equipment trouble automatically, improves the operating stability of terminal box, avoids the dehumidification equipment trouble to need can discover to the scene, and increases the condition of patrolling team work load.
In another embodiment of the present invention, a humidity control method based on an intelligent temperature and humidity controller includes the following logic: the method comprises the steps of edge calculation to judge that humidity is out of limit, judging that a dehumidifier is put into operation, edge calculation to judge the independent working time of the dehumidifier, humidity change rate judgment, first heating plate operation, humidity change rate judgment, edge calculation to judge the independent working time of the first heating plate, second heating plate operation and terminal box operation microenvironment marking.

It should be noted that the humidity threshold, the preset individual working time, the humidity return difference value, the humidity adjustment delay, the humidity adjustment variation, the temperature high-temperature threshold, the first heating plate adjustment delay, and the heating and dehumidifying adjustment rating value related in this embodiment may be pre-configured to the intelligent temperature and humidity controller, or may be adjusted according to the actual operation condition, which is not specifically limited in the embodiment of the present invention.

301, acquiring a real-time humidity value of the temperature and humidity sensor.
And step 304, judging the failure of the dehumidifier.
And 305, judging whether the investment time of the dehumidifier is greater than or equal to the preset single working time, if so, executing 306, and otherwise, continuing executing 305 after waiting for the set time.
And 307, stopping the operation of the dehumidifier.
It should be noted that the electronic components in the terminal box have strict temperature requirements during operation. If the temperature in the working environment of the electronic component does not meet the above temperature requirement, the working stability of the electronic component is affected, and even the service life of the electronic component is affected. Based on the consideration of the temperature requirement of the electronic element, the preset control strategy is configured in advance, and when the real-time temperature value in the terminal box exceeds the high-temperature threshold value of the temperature, the heating plate is prohibited to be started, so that the temperature in the terminal box is prevented from being increased.
Step 311, the first heating plate is put into operation.
And step 312, judging the fault of the first heating plate.
It should be noted that, based on consideration of the temperature requirement of the electronic component, the pre-configuration of the preset control strategy includes that when the real-time temperature value in the terminal box exceeds the high-temperature threshold value of the temperature, the heating plate is stopped to reduce the temperature in the terminal box.
At step 316, the first heater plate stops operating, and step 324 is executed.
Step 320, the second heating plate is put into operation, and step 324 is executed.
Step 321, second heater plate failure determination.
Step 322, determining whether the real-time temperature value is smaller than the high-temperature threshold, if so, executing step 324, otherwise, executing step 323.
And step 324, dehumidification end judgment.
