step (a): the temperature sensor, the humidity sensor and the voltage detection circuit are used for detecting the temperature, the humidity and the output voltage in the power transformation cabinet and transmitting the detected information to the singlechip module;
step (b): the singlechip converts the detected analog signals into digital signals through the analog-to-digital converter and transmits the digital signals to the communication module;
step (c): the communication module transmits the detection signal to the server through a wireless network;
step (d): the server stores the received signals in the memory and displays the signals on the display screen;
The remote control method of the transformer cabinet comprises the following steps:
step (1): the central processing unit compares the detected temperature and humidity with preset values, and the steps 2 and 3 are carried out;
Step (2): the central processing unit judges whether the temperature and the humidity are larger than preset values or not through comparison, if the temperature and the humidity are not larger than the preset values, step 4 is carried out, and if the detected temperature and humidity are larger than the preset values, the central processing unit sends instructions to the singlechip module through the communication module, and the singlechip module controls the exhaust fan and the dehumidifier to work and step 5 is carried out;
Step (3): the central processing unit judges whether the detected voltage value is within a qualified voltage range, if yes, the step 4 is entered, if not, the central processing unit sends an instruction to the single chip microcomputer module through the communication module, the single chip microcomputer module controls the relay group to release, the alarm gives an alarm, and the position of the power transformation cabinet with the problem is displayed on the display screen when the corresponding indicator light is extinguished;
Step (4): the detection module continues to detect the power transformation cabinet;
Step (5): and the temperature sensor and the humidity sensor continuously detect the temperature and the humidity in the power transformation cabinet and transmit the temperature and the humidity to the server to enter the step 2.
