Embodiment Construction

[0012] The invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] see figure 1 , the present invention arranges the axle counting wheel sensor in the obstacle monitoring area of ​​the railway line, and monitors the operation of the vehicle through the sensor. The axle counting information processing unit judges whether there is a train occupying the line obstacle monitoring area according to the train wheel set data in the line obstacle monitoring area monitored by the axle counting wheel sensor. When the number of wheel pairs of vehicles entering the line obstacle monitoring area is consistent with the number of wheel pairs of vehicles leaving the monitoring area, it is determined that there is no vehicle in the monitoring area, and when they are inconsistent, it is determined that the monitoring area is occupied by vehicles. An axle counting wheel sensor and an axle counting information processing unit connected to ...

Abstract

The invention relates to an automatic monitoring alarm method and system for a railway line obstacle. An axle counter device is arranged on steel rails at the two ends of a line obstacle monitoring zone, to monitor whether a train occupies the zone; a laser scanning device and a vibration sensor are adopted to monitor the line obstacle condition; whether an alarm is to be given is judged by combining the laser scanning information, vibration information and train occupation information. According to the invention, the train occupation condition of a railway rockfall section is monitored through the axle counter device with high reliability, the train vehicle can be accurately monitored, the false alarm caused by running of the train vehicle is eliminated, the false alarm rate of the automatic monitoring alarm system for the line obstacle through laser scanning is greatly reduced, and the availability of the system is effectively improved; a signal track circuit and transmission of train control information are not affected by the installation of the axle counter device, and the method and system can be used in a variety of block sections and train control modes, and have practicability.

Description

Technical field [0001] The invention relates to a method and system for automatic monitoring and alarming of railway line obstacles, belonging to the field of disaster prevention monitoring. Background technique [0002] There are many mountains in my country, accounting for about two-thirds of the country's land area. With the implementation of national strategies such as the Western Development, the mileage of mountainous railway lines has shown a trend of rapid growth in recent years. Due to the natural weathering of mountains, rainfall erosion, and artificial destruction of vegetation and other factors, mountain collapses and rockfall accidents on railway lines occur from time to time, which pose serious safety hazards to railway traffic. Therefore, monitoring and alarming of railway line collapses and rockfalls is particularly necessary . [0003] At present, the scheme for automatic monitoring of railway rockfall is realized. One of the main equipment is the automati...
