Tank body device based on PID control and control method thereof

Abstract

The invention provides a tank body device based on PID control and a control method thereof. The tank body device based on PID control comprises a tank body adsorbed on an adsorption surface; an air pump; an air pressure monitor which is arranged in the tank body and is used for detecting the air pressure in the tank body; and a controller which is connected with the air pressure monitor and is used for receiving the air pressure in the tank body, forming a control signal for changing the air pressure in the tank body if the detected air pressure is different from an air pressure set value, and outputting the control signal to the air pump so as to control the air pump and change the air pressure in the tank body. According to the present invention, the air pumping speed of the air pump is controlled through the output voltage, so that the air pressure in the tank body is kept at a set air pressure value, a certain vacuum degree is kept, and the air pressure is stable; meanwhile, the adjusting time of the control module is shortened, the anti-jamming capability of the system is improved, and the air pressure in the tank body can rapidly reach the set value; and the control method is simple and effective, the control efficiency is high, and the vacuum degree in the tank body is effectively controlled and kept.

Description

technical field [0001] The invention belongs to the technical field of pressure control, and relates to a tank device, in particular to a tank device based on PID control and a control method thereof. Background technique [0002] With the development of society, the pressure of people's work and life is gradually increasing, causing most of the staff to maintain a long-term sedentary posture in an air-conditioned environment for a long time, but lack of proper exercise, coupled with bad living habits, such as in the hot summer Drinking a lot of frozen drinks will cause moisture to invade the body. There is an old saying: "Thousands of colds are easy to get rid of, but once wet is hard to get rid of, the wetness is sticky, like oil in the face." The severity and harmfulness of moisture can be seen. The cupping is an effective dehumidification therapy. Cupping therapy is a traditional Chinese medicine therapy in our country. I believe that many people, especially middle-aged...

Problems solved by technology

[0005] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a tank device based on PID control and its control method, which is used to solve the problem that the actual air pressure corresponds to a Voltage range, so that there is a deviation between the actual voltage value and the theoretical voltage value, resulting in the problem that the air pressure cannot be accurately controlled and the response time is long
