After the upper computer sets given parameters, corresponding parameter data returned by the sensors are adjusted to a certain degree aiming at the electric control valve and the electric switch, so that data received by each parameter data display and the upper computer are changed in real time, and the adjustment is stopped when the corresponding parameters reach a certain range of the set parameters, so that feedback adjustment is realized, and finally, the change of the corresponding parameters is realized. Similarly, a manual speed regulating button and an emergency stop button are adopted in the whole system, so that the system can be treated when a fault occurs, and equipment is further protected. In the process, the electric appliance is matched with the emergency stop button to mainly control the electric control valve, the electric control switch and the corresponding indicator lamp, namely, the emergency stop button gives a signal after being pressed down, the electric control valve and the electric control switch are closed, and meanwhile, the corresponding indicator lamp is closed. After the speed regulating button is manually rotated, the passing current in the corresponding circuit is changed, so that the opening degree of the electric control valve and the electric control switch is controlled, and the change and the adjustment of parameters under the corresponding module are ensured.
