Embodiment Construction

[0023] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] like figure 1 As shown, a railway disaster prevention foreign matter invasion monitoring system includes three parts: monitoring point grid equipment, foreign matter invasion monitoring subunit, and monitoring host unit. The monitoring point grid equipment is connected to the foreign matter invasion monitoring subunit through a signal transmission channel. The foreign object intrusion monitoring sub-unit is connected with the monitoring host unit through a data transmission network.

[0025] Among them, the grid equipment at the monitoring point (hereinafter referred to as the grid equipment) adopts dual grid detection equipment, which is used for on-site sensing whether there is foreign matter invasion. The foreign matter intrusion monitoring sub-unit includes a grid module connected to the grid equipment through a sig...

Abstract

The invention provides a railway disaster-preventing foreign body invasion-limiting monitoring system, comprising a monitoring point grid apparatus, a foreign body invasion-limiting monitoring subunit and a monitoring host unit, wherein the monitoring point grid apparatus is connected with the foreign body invasion-limiting monitoring subunit through a signal transmission channel; the foreign body invasion-limiting monitoring subunit is connected with the monitoring host unit through a data transmission network; and the foreign body invasion-limiting monitoring subunit comprises a grid module connected with the monitoring point grid apparatus through the signal transmission channel, and a monitoring module for acquiring a detection signal in the signal transmission channel. The monitoring module judges the states of the signal transmission channel, the grid module and the monitoring point grid apparatus by acquiring the voltage amplitude and the alternating current frequency of each alternating-current signal between the grid module and the monitoring point grid apparatus, and analyses a foreign body invasion-limiting result; as a result, the influence of self equipment faults on the foreign body invasion-limiting result is eliminated; and the reliability and the usability of the system are improved.

Description

technical field [0001] The invention relates to a railway disaster prevention and foreign object invasion limit monitoring system, which belongs to the railway disaster prevention safety monitoring system. Background technique [0002] The railway disaster prevention and safety monitoring system is an integrated system for disaster prevention and disaster reporting composed of wind monitoring subsystem, rainfall monitoring subsystem, snow depth monitoring subsystem, earthquake monitoring subsystem and foreign object intrusion monitoring subsystem. The railway disaster prevention and safety monitoring system is an important part of the high-speed railway safety guarantee, and plays an important role in the high-speed railway traffic guarantee system. In practical applications, traffic dispatchers command the safe operation of trains based on real-time monitoring, early warning and alarm information of safety environments such as wind, rain and snow, earthquake disasters, and ...
