Embodiment Construction

[0014] figure 1 and figure 2 It is a schematic diagram of a typical embodiment of the present invention. The schematic diagram includes the signal sending and receiving main circuit structures of the monitoring station of the train and the leading monitoring vehicle, and the vehicle-mounted wireless mobile communication system composed of them.

[0015] figure 1 It is a structural schematic diagram of the leading monitoring car signal sending and train end signal receiving circuit in this embodiment. In the figure: multiple monitoring cameras (1) are installed at the front end of the leading monitoring vehicle and other required parts, and the video and audio analog signals of the cameras are converted into digital signals by the A / D conversion circuit (2), and then compressed and encoded by the circuit (3) Convert to MPEG data signal. While the leading monitoring vehicle collects the camera signal, it also uses the leading monitoring vehicle data acquisition and processin...

Abstract

A train driving safety monitoring device, mainly composed of a train monitoring signal system, a leading monitoring vehicle monitoring signal system, and a wireless communication system. The leading monitoring vehicle travels synchronously near the safe braking distance in front of the train, and a monitoring camera is installed on the leading monitoring vehicle An image monitor is set in front of the train driver's operating position, and images and data information are transmitted between the leading monitoring vehicle and the train through the vehicle-mounted wireless mobile communication system. Since the image monitoring of the leading monitoring vehicle extends the driver's field of vision forward, the road conditions beyond the safe braking distance ahead can be observed in real time. When an abnormality is found ahead, emergency braking or other emergency measures can be taken within the effective safe distance.

Description

technical field [0001] The invention relates to a train running safety monitoring device, in particular to a rail train running safety monitoring device capable of realizing remote video real-time monitoring. Background technique [0002] In recent years, with the rapid development of railway transportation technology, the operating speed of high-speed trains has increased to more than 300 km / h. How to ensure that when the train is running at high speed, it is very important to make a stop or other emergency treatment within the specified distance in case of sudden abnormalities ahead. For this reason, people have conducted in-depth research on emergency braking technology under high-speed operation and achieved certain results. However, in view of the increase in the speed of modern high-speed trains, their running kinetic energy increases, the available wheel-rail adhesion coefficient decreases, and the braking distance required to dissipate unit kinetic energy increases....
