Gate passage detection system and method

Abstract

The invention discloses a gate passage detection system and method. The gate passage detection system comprises a gate, photoelectric distance detection devices and a channel processing device, wherein the photoelectric distance detection devices are arranged on the same gate; the photoelectric distance detection devices and the gate are respectively connected with the channel processing device; each photoelectric distance detection device comprises an optical component, a pre-amplifying module and a microprocessor; the optical component is used for sending and receiving infrared ray; the pre-amplifying module is used for amplifying the signal output by the optical component; and the microprocessor is used for carrying out filtering and demodulating the amplified signal, calculating to obtain a moving distance, a moving speed and a position, and sending the obtained data to microprocessor of the channel processing device. The gate passage detection system and method have the advantages that: the photoelectric distance detection devices are used for measuring the distance as well as the moving speed and the time of an object, and transmitting the detection data to the channel processing device in real time; and the channel processing device is used for correspondingly controlling the opening or closing of a gate door of the gate, thus the management requirement of the gate passage is met.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a gate channel detection system and a detection method thereof. Background technique [0002] In order to ensure the rapidity, stability and reliability of the automatic ticket checking system, the gate channel control system needs to detect the status of the gate channel in real time. And follow-up situation for real-time processing and other functions. [0003] The signal detection principle of the traditional gate channel is as follows: figure 1 As shown, the detection device includes an infrared transmitter 11 and an infrared receiver 12. When there is no object 13 to be measured between the infrared transmitter 11 and the infrared receiver 12, the infrared receiver 12 can receive the signal emitted by the infrared transmitter 11 , when there is an object 13 to be measured between the infrared transmitter 11 and the infrared receiver 12, the infrared receiv...
