thirdly, buffering when clamping a person, wherein the first motor (10) drives the cavity shell (6) to swing, when the person passes through the space between the first shell (2) and the second shell (3) when the gate is closed, the buffer plate (7) is firstly contacted with the person at the moment, the buffer plate (7) is rotatably installed in the cavity shell (6), when the buffer plate (7) is extruded, the air pressure in the cavity shell (6) is increased, the pressure sensor (15) detects the change of the pressure at the moment and transmits a pressure signal to the PLC (16), the PLC (16) controls the electromagnetic valve (12) to be opened, after the electromagnetic valve (12) is opened, the air in the cavity shell (6) can be discharged through the exhaust joint (13), and the buffer plate (7) can be retracted into the cavity shell (6) at the moment;
the fourth step, the reset of device, after a period of time in buffer board (7) shrink cavity shell (6), PLC (16) control solenoid valve (12) are closed this moment, the work of simultaneous control air pump (9), air pump (9) during operation, to gas injection in cavity shell (6), cavity shell (6) internal gas pressure crescent, under the effect of atmospheric pressure, make buffer board (7) stretch out in by cavity shell (6) gradually, constitute the gate of a completion once more, when pressure sensor (15) detected cavity shell (6) internal pressure and reached the default, air pump (9) stop work.
