High-speed railway platform end anti-crossing alarm system and method based on microwave radar

Abstract

The invention discloses a high-speed railway platform end anti-crossing alarm system based on microwave radar, which comprises a central control module, a radar sensor, a voice broadcaster, a video recorder and a warning lamp. The radar sensor includes a signal transmitting unit and a signal receiving unit. The signal transmitting unit transmits an electromagnetic wave signal to an obstacle to monitor a monitored object. The signal receiving unit mixes the received electromagnetic echo signal with a local oscillation signal to get an echo intermediate-frequency signal, extracts the echo intermediate-frequency signal to obtain distance and echo power information of the monitored object, and determines the type of the monitored object by analyzing the distance and echo power information. Thevoice broadcaster produces a corresponding alarm sound for warning according to the type of the monitored object. The video recorder collects the video information of the monitored object. The warning lamp gives a light alarm according to the type of the monitored object. The central control module displays the collected monitoring information to the monitoring personnel to assist in off-line operation.

Description

technical field [0001] The invention relates to the technical field of high-speed rail, in particular to a microwave radar-based anti-crossing alarm system and method at the end of a high-speed rail platform. Background technique [0002] With the development and popularization of China's high-speed rail technology, the role of high-speed rail security is particularly important. High-speed rail security mainly includes: station and railway security, compartment security and electronic security in the vehicle. Among them, the security of the car and the electronic security in the car, because the personnel are relatively fixed, the space is small and there are staff patrolling, so the security work is relatively simple. The security of stations and railways is heavy because of the complex movement of personnel and the large space, so the workload is heavy and the tasks are heavy. The main security measures include electronic fences, road monitoring, and power failure system...
