Remote automatic alarm and positioning system for disconnection of fixed-line telephone and network communication cable

Abstract

The invention relates to a remote automatic alarm and positioning system for the disconnection of a fixed-line telephone and a network communication cable. The system comprises an on-site alarm and positioning device and a remote alarm and positioning receiving end, wherein the on-site alarm and positioning device is arranged at one end of an outdoor overhead cable in a section where scraping andcollision are most likely to happen, and the interior is provided with a control module and a breakpoint wireless remote transmission module. The system is provided with a safety line, and the safetyline is wound on the outdoor overhead cable, wherein one end of the safety line is fixed with the cable, and the other end is inserted into a safety cable hole of the on-site alarm and positioning device and serves as a disconnection fault alarm dynamic contact on the control module. When the cable is scratched and broken, the safety line is pulled out of the safety line hole, the dynamic contactis separated from an on-off point on the control module, the control module is connected with the breakpoint wireless remote transmission module, and a fault signal is sent to a remote alarm and positioning receiving end in a short message mode through an off-circuit wireless remote transmission module. According to the invention, the system achieves the quick recovery of the normal operation of telephone and network communication, and achieves the minimum loss at minimum cost.

Description

Technical field [0001] The invention relates to a cable detection system, in particular to a remote automatic alarm positioning system for fixed telephone and network communication cable disconnection. Background technique [0002] Most of the large coal mining companies are composed of multiple mining areas, and the distance between each mining area and the headquarters is more than ten kilometers. This creates overhead lines for fixed telephone communication and Internet communication between the headquarters and the mining area or between the mining area and the mining area. It is necessary to cross the complex terrain such as urban areas, highways, farmland and wilderness, so it is very troublesome to find the disconnection point by tens of kilometers, which is time-consuming and laborious. The most important thing is that the long-term telephone and network communication interruption will cause production Bring heavy losses. Therefore, a remote automatic alarm location syst...
