Problems solved by technology

In addition, when the railway engineering and electrical departments are working on the line, the protective personnel cannot immediately find the train approaching the work site, so traffic accidents may also occur
For this reason, a lot of crossing alarms or automatic alarm devices have occurred in the prior art, as in patent documents CN 2111905U (Zhang Dehui), CN 2167912Y (Shaoguan Iron and Steel Works) and CN 1358147A (Siemens) all disclose a kind of crossing Alarm devices, in the technical solutions disclosed in these documents, sensors are set on the line at a certain distance from the crossing, and when the train triggers these sensors, an alarm signal is sent, but such an alarm device can only start to alarm when the train reaches a certain distance , cannot provide dynamic information about train operation
In the prior art documents CN 2106764U (Huang Fuxia), EP 11185

Abstract

The present invention discloses a digital railway crossing safety early warning device and method. The early warning device can perform radio communication with train running in railway, and works on comprehensive digital station. The early warning device receives the approach signal the train sends and sends to the train the crossing status information. It has digital work mode and its radio emitting and receiving frequency channel dissimilar to that for train scheduling. Owing to the far transmission distance, fast rate, low error code rate and standard interface, the present invention has no problems of co-channel interference and radio train scheduling signal cross-talk, and can realize the high reliability data transmission between the train and the approached crossing.

Description

technical field [0001] The invention relates to a railway crossing device and a working method thereof, which is used for receiving an early warning signal sent by a running train when the train approaches the crossing, and can send an alarm signal related to the crossing situation to the running train. Background technique [0002] The safety of railway crossings is a prominent issue related to the safety of railway transportation. The number of traffic accidents occurring at railway crossings is very large every year. With the continuous improvement of the speed of railway trains, the accident rate of railway crossings has increased significantly. In addition, when the railway engineering and electricity departments are working on the line, the guards cannot immediately find the train approaching the work site, so traffic accidents may also occur. For this reason, a lot of crossing alarms or automatic alarm devices have occurred in the prior art, as in patent documents CN ...
