Embodiment Construction

[0012] specific implementation plan

[0013] The railway vehicles currently in operation are all air brakes, and the brake supervisor must keep

[0014] In the through state, the pressure air in the brake main pipe is 600kPa. When it is necessary to perform normal braking on the train, the driver manipulates the automatic brake valve of the locomotive to smoothly discharge a part of the pressure air in the brake main pipe; when emergency braking is required, quickly discharge the pressure air in the brake main pipe.

[0015] It can thus be concluded that the air pressure in the braking supervisor of the train is 600kPa when the train is in operation; The air pressure in the main pipe drops rapidly to zero. In this way, the running state of the train can be accurately judged by monitoring the regularity of the pressure change of the main train brake.

[0016] Referring to Fig. 1: the wireless early warning device (4) of this scheme is installed on the vehicle (3) at the rear...

Abstract

The invention relates to a radio pre-warning device for preventing rear-end collision of trains, which comprises a micro processor (4), an accumulated battery (3), a radio station (5), a pressure sensor (10), an input button (9), etc., which are installed at the tail part of a running train; a high-pressure soft tube (1) is communicated with a main brake pipe of the train. When the train runs, the micro processor (4) monitors the information of changed pressure of the brake pipe of the train by inquiring the pressure sensor (10); when the train is judged to have to emergently stop, the micro processor controls the radio station (5) to continuously transmit the radio alarm signal of, ''No. ''XX'' train is forced to stop and the ''X'' bound train, please do not get close!'', and a strong light protective lamp (6) flashes to conduct assisting protection, so as to remind the drivers of the following trains to take safety measures to prevent the rear-end collision.

Description

technical field [0001] The invention relates to an early warning device for preventing rear-end collisions of railway trains, in particular to a wireless early-warning device for preventing rear-end collisions of subsequent trains. technical background [0002] Passenger trains of railways sometimes encounter unexpected emergencies and are forced to temporarily stop in the section during operation. In order to prevent rear-end collisions of follow-up trains, protective personnel protect the rear of the temporarily parked trains. However, when running into curves, bad weather or other situations, the driver following the train sometimes cannot find the protection signal of the stop train in time, and the train rear-end collision accident occurs very easily. Several disastrous train rear-end accidents have occurred in the railway system in recent years. It can be seen that the railway system has serious hidden dangers in preventing subsequent train rear-end collisions. Conte...
