Problems solved by technology

[0003] However, the dual grid monitoring technology mainly has the following problems: First, there are certain requirements for the grid cross section and the bearing capacity of the grid wires. When the weight of foreign objects is less than the bearing capacity of the grid wires, the grid will not be broken, so No alarm message will be generated
The use of radar technology in the detection of railway foreign object infringement has not yet been reported

Abstract

The invention discloses an apparatus for detecting railway foreign matter intrusion, comprising a primary radar apparatus, a spare radar apparatus, an on-site controller and a monitoring unit, wherein the primary radar apparatus and the spare radar apparatus are oppositely arranged at both sides of the detected railway; the on-site controller is respectively connected with the primary radar apparatus and the spare radar apparatus, and is disposed inside the primary radar apparatus; the monitoring unit is connected with the on-site controller via a communication cable; and the primary radar apparatus, the spare radar apparatus and the monitoring unit are connected so as to transmit a data signal. The apparatus can increase the monitoring reliability to meet the high reliability requirementof the railway, and can enhance the precision of remote monitoring, so that the monitoring is more flexible; the radar apparatus can be flexibly installed without the limit of terrains and the like; the monitoring distance is long; and the alarm response speed is higher and can be reported more promptly. The apparatus has the function of inquiring and setting the on-site radar apparatus without continuously watching the monitoring interface by people, and also has the function of monitoring moving objects in real time and alarming in advance.

Description

technical field [0001] The invention relates to a detection device for railway foreign objects, in particular to a device for detecting the invasion of railway foreign objects. Background technique [0002] At present, there is no effective means to realize the monitoring of foreign matter intrusion in the area of ​​public-span iron bridges and road-rail parallel (including within 1.5 below the railway). Some monitoring points apply dual-grid monitoring technology. This technology is to lay two insulated wires on the protective net. As long as there is a grid with a cross-section larger than the dual grid, and a foreign object whose mass is greater than the bearing capacity of the grid wire falls on the protective net, the wire will be cut off and an alarm message will be generated. [0003] However, the dual grid monitoring technology mainly has the following problems: First, there are certain requirements for the grid cross section and the bearing capacity of the grid wire...
