Sensor system for detecting obstacles of platform door and detection method of sensor system
The invention discloses a sensor system for detecting obstacles of a platform door and a detection method of the sensor system. The sensor system comprises a plurality of sensor groups which are uniformly mounted on the side, close to train travelling, of the platform door; each sensor group comprises two photoelectric sensors; the photoelectric sensors are arranged in the direction perpendicularto the platform door, and the detection distance in the direction perpendicular to the platform door is equal to the vertical distance between the platform door and a train; the sensor groups are connected with an embedded chip and are used for processing input signals of the photoelectric sensors; and when any sensor detects an obstacle, the sensor groups output a high level. The triggering sequence of the photoelectric sensor groups in each time period from the entering period to the exiting period of the train is detected, whether the obstacle exists between a train door and the platform door or not is correctly judged when the triggering sequence deviates from the normal triggering sequence, and a control instruction is sent by the embedded chip to realize obstacle detection and traindoor opening and closing state monitoring.
本发明公开了一种用于站台门障碍物探测的传感器系统及其探测方法，所述传感器系统包括若干均匀安装在站台门靠近列车行驶一侧的传感器组；每个传感器组包括2个光电传感器；所述光电传感器沿垂直于站台门方向设置，沿垂直于站台门方向的探测距离与站台门和列车间的垂直距离相等；所述传感器组与嵌入式芯片相连，对光电传感器输入信号进行处理；当任一传感器检测到障碍物时，传感器组输出高电平。检测列车从进站到出站各个时间段光电传感器组触发顺序，在偏离正常触发顺序时，正确判断列车门和站台门之间是否存在障碍物，由嵌入式芯片发出控制指令，实现障碍物探测和列车门开关状态监测。
