Negative-pressure physical training equipment control system with loading work capacity, and control method thereof

Abstract

The invention discloses a negative-pressure physical training equipment control system with loading work capacity. A microprocessor is connected with a sampling signal filtering and amplifying circuit, a D/A output amplifying circuit and an optically-coupled isolation amplifying circuit, and the sampling signal filtering and amplifying circuit is connected with a pressure sensor. A control method comprises the following steps: (1) sampling a real-time pressure value in a negative-pressure cabin by the pressure sensor, processing the real-time pressure value by the sampling signal filtering and amplifying circuit, and then transmitting the real-time pressure value to the microprocessor; (2) transmitting the real-time pressure value to an upper computer by the microprocessor, and transmitting a real-time power value to the microprocessor; (3) processing a power signal by the D/A output amplifying circuit, and then driving a magnetic powder clutch; (4) achieving pressure adaptive control through a control algorithm and a sampling signal filtering algorithm embedded by the upper computer, and regulating an electromagnetic valve to be turned on or off; (5) displaying and setting operation parameters by the upper computer, controlling the operation of the system, and monitoring an operation state of the system in real time in an operation process. The system is simple and reliable in structural design, low in cost, and simple and convenient to operate, and automatic operation can be achieved.

Description

technical field [0001] The invention belongs to the field of aerospace, and in particular relates to a control system and a control method for a negative pressure physical fitness training device that performs work under load. Background technique [0002] With the emergence and successive service of high-performance fighter jets, positive acceleration (+Gz)-induced loss of consciousness (G-LOC) in flight has gradually increased. This is the main factor that reduces the working ability of pilots, and is also the main reason that threatens the safety of pilots. Carrying out anti-load exercise training on the ground has certain limitations. At the same time, during spaceflight, weightlessness will cause cardiovascular dysfunction of astronauts, resulting in poor orthostatic endurance, muscle atrophy and bone loss, etc. Currently, various countermeasures are adopted, but none of them can completely effectively combat the above-mentioned changes caused by weightlessness. Only ...
