Abstract
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...
