Background
At present, urban rail transit plays a very important role in urban public transportation, and the characteristics of high efficiency, rapidness and the like also enable passengers to select the primary factor of urban rail transit. The subway shield door isolates the platform from the tunnel, and provides a safe and comfortable environment for passengers to wait for a bus. However, there is a gap of at least 10cm between the screen door and the vehicle door, and if people are caught in the gap between the screen door and the vehicle door, an operation safety accident may be caused, and even casualties may be caused. In response to this problem, some detection techniques, such as head-to-tail laser irradiation, head-to-tail infrared irradiation, video image analysis-based techniques, and the like, have been proposed in recent years.
The head and tail laser irradiation type is easy to cause false detection due to vehicle body reflection, and the head and tail infrared irradiation type is easy to cause diffraction to cause false detection; the video image analysis technology is easily influenced by factors such as the change of the platform illumination environment, the distance between the platform illumination environment and a camera and the like, so that the defects of low accuracy rate and the like are caused. In addition, the equipment is relatively large in volume, and the equipment is easy to intrude when being installed in a narrow space and the position of the foreign matter cannot be quickly determined.

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 foreign matters in gaps between a shield door and a vehicle door comprises a train detector 1 for detecting whether a train enters a station, an alarm 2, a ranging scanner 4 for measuring a ranging distance from the ranging scanner 4 to the vehicle door, a shield door signal system 5 for outputting a shield door opening and closing signal, and a foreign matter detector 3, wherein the output ends of the ranging scanner 4 and the shield door signal system 5 are respectively connected with the input end of the foreign matter detector 3, and the output ends of the foreign matter detector 3 and the train detector 1 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 shield door and the vehicle door further comprises end door uprights 6 located at two ends of the subway platform, and the train detector 1 and the alarm 2 are respectively installed on the end door uprights 6.
As shown in fig. 1 to 3, each of the shield doors is provided with the range-finding scanner 4 and the foreign object detector 3.
As shown in fig. 1 to 3, the foreign matter detector 3 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.
As shown in fig. 1 to 3, the range scanner 4 is installed to be inclined with respect to a horizontal plane.
The utility model provides a pair of gap foreign matter detecting system between shield door and door, train detector 1 is responsible for detecting whether the train enters station, and in time transmit the testing result to alarm 2, shield door switch door signal is direct to insert to foreign matter detector 3 from shield door signal system 5, range finding scanner 4 transmits the measuring result to foreign matter detector 3 in real time, in order to increase the detection space, range finding scanner 4 when the installation, certain angle of side drift towards the train, measure the distance of range finding scanner 4 to the train door, 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 range finding scanner 4's data, and then judge whether there is the foreign matter in the gap between door and shield door. If the train detector 1 detects a train arrival signal, the alarm 2 starts to process data transmitted by the foreign matter detector 1 corresponding to each vehicle door.
