每当有人从内部到外部或从外部到内部通过光电开关时，光电开关感应到信号并

Whenever someone through the photoelectric switch, photoelectric switch or sensor from the outside to the inside from the outside to the inside and simultaneously a signal to the PLC sends a pulse to the master controller, and then transmits the control command from the positive direction of rotation of the motor main controller PLC. The positive rotation direction and the motor driven ball screw transmission mechanism such rail movement causes the shelter door opening event. When the door is fully open shelter active switch when the limit is reached, the motor stops rotating and the timer started immediately enters state timing after 10 seconds until the timers to complete, then automatically enter the shelter movable door closed state, at this time the motor back so that rotation of the shelter to the other guides and ball screw driven motion transmission mechanism is closed tambour. When the hatch reaches a fully closed limit switch, the motor stops rotating immediately. During active gate opening or closing, if someone from inside to outside or from outside to inside through the movable door safety sensors detector will immediately signal is detected, at which time you should immediately stop the door open or close the tambour activity.

每当有人从内部到外部或从外部到内部通过光电开关时，光电开关感应到信号并同时发送一个脉冲给到 PLC 主控制器，然后由PLC主控制器发送指令控制电机的正方向转动。电机正方向转并带动滚珠丝杆导轨等传动机构运动使方舱活动门开启。当方舱活动门完全开启到达上限位开关的时候，电机立刻停止转动同时定时器开始进入计时的状态，直到10秒后计时器完成计时，此时方舱活动门自动进入关闭状态，此时电机反向转动并带动滚珠丝杆导轨等传动机构运动使方舱活动门闭合。当活动门完全闭合到达下限位开关时，电机立刻停止转动。在活动门开启或者关闭的过程中，如果有人从内部到外部或从外部到内部通过活动门时，安全感应探测器会立刻检测到信号，在此时应立即停止开启活动门或关闭活动门。

Whenever someone passes through the photoelectric switch from the inside to the outside or from the outside to the inside, the photoelectric switch senses the signal and sends a pulse to the PLC main controller at the same time, and then the PLC main controller sends the command to control the positive direction of the motor. The motor rotates in the positive direction and drives the driving mechanism such as ball screw guide rail to open the movable door of the shelter. When the movable door of the square cabin is fully opened and reaches the upper limit switch, the motor immediately stops rotating and the timer starts to enter the timing state until the timer finishes timing 10 seconds later. At this time, the movable door of the square cabin automatically enters the closing state. At this time, the motor reversely rotates and drives the driving mechanism such as the rolling bead screw guide rail to close the movable door of the square cabin. When the movable door is fully closed to the lower limit switch, the motor stops rotating immediately. In the process of opening or closing the movable door, if someone passes through the movable door from the inside to the outside or from the outside to the inside, the safety sensor detector will immediately detect the signal, and at this time, it shall immediately stop opening or closing the movable door.<br>
