The number of the relays 7 is plural.
In some embodiments, the control cabinet further comprises a switching power supply 5 arranged in the cabinet body, an output end of the switching power supply 5 is connected with the controller 4, the frequency converter 9 and the contactor group, power input ends of the switching power supply 5, the frequency converter 9 and the contactor group are all provided with an air switch 1, and an input end of the air switch 1 is provided with a circuit breaker 2.
In some embodiments, as shown in fig. 2, a display screen 11 is disposed on the cabinet door of the cabinet, and an indicator light 12 is disposed on the cabinet door of the cabinet.
The controller 4 adopts the PLC controller, therefore needs IO board 3 to carry out input/output signal's conversion, and after air conditioning system started, the output signal of controller 4 inserts the coil of relay 7, opens motorised valve and governing valve on the tuber pipe through relay 7, and the motorised valve passes through inductive switch output feedback signal, and the governing valve corresponds the aperture of its valve through what output analog quantity signal. The frequency converter is used for an exhaust fan 14 and an air supply fan 15 of the air conditioning system, and is communicated with the programmable logic controller 4 in an industrial Ethernet mode, the controller 4 changes the frequency of the fan by changing the frequency of the frequency converter 9, and meanwhile, the frequency of the fan is fed back to the controller 4.

The controller and remote IO modules used here are Siemens S7-1500 series and ET200SP series. The temperature sensor adopts a two-wire system sensor, adopts current type input, has the range of 4-20mA, and can convert a temperature signal into an electric signal and send the electric signal to the controller.
Before the air conditioning system is started, a worker sets a target temperature in a public area of a station hall on a touch screen and then presses a start button. When the system is started, equipment of the air conditioning system starts to operate, meanwhile, the temperature sensor collects the temperature of the public area of the subway station hall, and sends the collected temperature to the controller for processing in the form of an analog quantity signal. The controller carries out PID control according to the deviation of the temperature set by the staff and the average value of the measured temperature, changes the air volume brought by the fans by changing the running frequency of the fans, and finally achieves the function of automatic temperature regulation in the public area of the subway station hall. On the other hand, the system can also realize the function of monitoring equipment in the air conditioning system in real time by subway workers. When equipment of the air conditioning system breaks down, the alarm point is triggered at the moment, an alarm window pops up, and the touch screen can give out buzzing sound to remind workers of timely processing. The alarm points can be added to the alarm records to form an alarm trend graph, so that the alarm information is visualized, and the records can be conveniently checked by workers.
