Detailed Description

The present invention will be further described with reference to the following description and embodiments.

As shown in fig. 1 to 3, a system for detecting a gap foreign matter between a shield door and a vehicle door of a subway platform comprises a train detector 1 for detecting whether a train enters a station, an alarm 2, a weight sensor 4 for detecting the weight of a pedal position of the shield door, a shield door signal system and a foreign matter detector 3, wherein the output ends of the weight sensor 4 and the shield door signal system are respectively connected with the input end of the foreign matter detector 3, the shield door signal system provides a shield door opening and closing signal for the foreign matter detector 3, and the output ends of the train detector 1 and the foreign matter detector 3 are respectively connected with the alarm 2.

As shown in fig. 1 to 3, the foreign object detector 3 is a single chip microcomputer, and is ATmega 128A.

As shown in fig. 1 to 3, the system for detecting foreign matters in the gap between the screen door and the car door of the subway platform further comprises end door uprights 5 positioned at two ends of the subway platform, and the train detector 1 and the alarm 2 are respectively installed on the end door uprights 5.

As shown in fig. 1 to 3, each of the shield doors is provided with a weight sensor 4 and a foreign object detector 3.

As shown in fig. 1 to 3, the foreign matter detector 4 is installed inside the top door cabinet of the shield door.

As shown in fig. 1 to 3, the alarm 2 is connected with an indicator light and a display screen.

The utility model provides a pair of space foreign matter detecting system between subway platform shield door and door, accessible train detector 1 detects the train and whether enters the station, and in time transmit the testing result to alarm 2, accessible shield door signal system obtains shield door switch door signal, replace the original pedal position of platform shield door for weight inductor 4, weight inductor 4 transmits the measuring result to foreign matter detector 3 in real time, after foreign matter detector 3 received the signal that the shield door was closed the door and was locked tightly, foreign matter detector 3 handled the data of weight inductor 4, and then judge whether there is the foreign matter in the space between door and shield door. If the foreign object alarm information exists, the foreign object alarm information is sent to the alarm 2, and if the foreign object alarm information does not exist, the foreign object alarm information is not sent to the alarm 2.
