A Remote Sensing Tunnel Train Passing Early Warning System

Abstract

A remote sensing tunnel train passing warning system, which includes a power adapter to provide stable power for signal acquisition equipment, a microcontroller, and a signal emission unit; the signal acquisition equipment includes an infrared sensor, and the signal acquisition equipment is installed on the sidewall of the tunnel , collect the train movement information, and transmit the collected train movement information to the microcontroller in real time through the data line; the microcontroller, the microcontroller analyzes the train movement information collected by the signal acquisition equipment, and sends out Specific signal; wireless signal transmitting unit, wirelessly transmits the signal from the microcontroller in real time; hand-held terminal equipment, receives the signal from the wireless signal transmitting unit, performs information verification, and activates different reminder devices according to different signals.

Description

Technical field [0001] The invention relates to a remote sensing train passing early warning system, in particular to a remote sensing train passing early warning system in a tunnel. Background technique [0002] Judging from the current operating status of electrified railways, the method of protection for line operators on railways basically adopts the protection of station liaison officers and on-site driving protectors. The protection of station liaison officers has the problem of unclear location of trains and inconvenient communication. Disadvantages: the protection work of the on-site driving guards is easily affected by bad weather and topography (curves, tunnels), especially in the tunnels, the driving protection warning is not in place, and the personnel, equipment and materials cannot be evacuated to the safe zone in time. The safety of people and the safety of trains have brought huge hidden dangers. my country has a vast land and numerous mountainous areas. As a res...

Problems solved by technology

[0003] With the improvement of train speed and the continuous increase of railway traffic volume, the gap between trains is getting shorter and shorter, which brings unsafe hidden dangers to inspections or other maintenance operations on the railway.

Especially in the tunnel, when the train passes through the tunnel, there may be another train passing through before the dust falls. The operators in the tunnel must have a high awareness of safety, and the traffic guards must have strong operating experience. Even so, it is impossible to completely avoid misjudgment, which brings great potential safety hazards to personal and driving safety.
