The application discloses a kind of self-adapting air
pressure balance sliding door control systems, it is related to sliding door control technical field.The sensor layer, PID control module, execution layer and prediction maintenance module are included;Sensor layer gathers
pressure difference, sealed pressure, vibration, door position, temperature and
humidity and other data, PID control module uses the
improved algorithm with nonlinear correction and output amplitude limiting, the
pressure difference is stabilized at 2Pa target value, simultaneously through
closed loop PID, hydraulic sealed pressure is stabilized at 1.0MPa, and anti-integral saturation and output amplitude limiting are configured to ensure
operation safety;Execution layer includes
servo motor drive sliding door, hydraulic sealing
system, emergency pressure
relief valve and audible and visual
alarm device;Prediction maintenance module is based on
random forest regression model, according to the characteristics such as sealed pressure drop rate, valve
response time, motor current variance, vibration level, operation frequency, remaining service life is predicted, and maintenance suggestion is output according to critical, early warning, normal classification.
