Abstract

The invention discloses a low-voltage signal controlled centering and deviation rectifying control system of pneumatic control and pneumatic states. The low-voltage signal controlled centering and deviation rectifying control system is characterized by comprising a deviation rectifying air cylinder and a connecting rod controlled by the deviation rectifying air cylinder, wherein the connecting rod is connected to a controlled object; the deviation rectifying air cylinder is connected with a pneumatic control valve; the controlled object is arranged in a gas source signal generator; the gas source signal generator is connected with the pneumatic control valve through a pneumatic amplifier. The invention further provides a low-voltage signal controlled centering and deviation rectifying control method of the pneumatic control and pneumatic states. The low-voltage signal controlled centering and deviation rectifying control system and method of the pneumatic control and pneumatic states have the beneficial technical effects that (1) a low-voltage weak signal of a pneumatic control system is used for controlling middle-voltage to high-voltage action execution; (2) an anti-pollution capability is high and incorrect actions caused by dust pollutant interference are not caused; (3) compared with an electric control manner, the low-voltage signal controlled centering and deviation rectifying control system and method are safe and can work safely under a humid environment; dust is not detonated due to discharging of an electric contact under a dust environment.

Description

technical field [0001] The application relates to the field of deviation correction control of mechanical equipment, in particular to an air control and pneumatic dynamic centering deviation control method and system controlled by a low pressure signal. Background technique [0002] In the process of metal strip, weaving, printing and dyeing, paper, plastic film winding and conveyor belt, steel belt, and fast belt sander, the deviation correction device is usually required to work together. The control methods of traditional correction equipment include photoelectric signal control, electric control, air control and other forms. Because the air control method has strong anti-pollution and high stability, it is widely used. However, the deviation correction system controlled by the air control method in the prior art usually adopts the mode of controlling the movement of the low-pressure air by the medium-high pressure air signal. This not only results in low energy utiliza...
