The present embodiment provides an automatic control device for an exhaust gas pumping system, as shown in fig. 1-2, including an exhaust gas pumping system; the tail gas pumping and discharging system comprises a long slide rail 101, a fan 100 and a plurality of tail gas suction nozzles 104, wherein the upper ends of the tail gas suction nozzles 104 are fixedly connected with a sliding support 105, the sliding support 105 is slidably arranged on the long slide rail 101, and the fan 100 is communicated with the tail gas suction nozzles 104; the device also comprises a control device, wherein the control device comprises an induction device 1 and a control cabinet 2; the control cabinet 2 comprises a controller 21 and a pulse relay I22, the fan 100 is connected to the power supply 3 through the pulse relay I22, and the controller 21 is connected to the pulse relay I22 and used for outputting a pulse signal to the pulse relay I22; a plurality of sensing devices 1 are fixed on the long slide rail 101, each sensing device 1 is connected to the controller 21 through a signal line in a communication mode, and the sensing devices are used for sensing whether a sliding support reaches the position of the sensing device or not; the controller 21 is electrically connected to the power supply. In practical application, a field is generally divided into a plurality of stations 103, and each sensing device 1 is arranged corresponding to each station 103.

The working principle of the automatic control device of the tail gas pumping and exhausting system is as follows: the power supply 3 supplies power to the controller 21, and the controller 21 supplies power to each of the induction devices 1. The sensing device 1 detects whether a sliding support arrives at the position where the sensing device is located in real time and transmits a detection signal to the controller 21. When the automobile 102 drives into the station 103 for parking the automobile, a worker slides the tail gas suction nozzle 104 to the induction device 1 corresponding to the station 103 through the connected sliding support 105, the induction device 1 transmits a detection signal to the controller 21 when detecting that the sliding support 105 arrives, the controller 21 sends a pulse signal to the first pulse relay 22, the first pulse relay 22 is closed, and the fan 100 is powered on and starts to operate.
