A buried feeder and buried cable magnetic field positioning monitoring and alarm system

Abstract

The invention provides a buried feeder line and buried cable magnetic field locating monitoring alarm system, belongs to the technical field of magnetic field monitoring locating alarm, and particularly relates to the buried feeder line and buried cable magnetic field monitoring alarm system. The system comprises a buried magnetic field locating monitoring device, a signal receiving and transmitting device, a control center server, an alarm center server, a mobile terminal and a surface magnetic field locating monitoring device. The following beneficial effects can be realized: the inspectionand field work frequency of the work personnel can be reduced, the land excavation area can be reduced under the accident state, the number of the maintenance personnel can be reduced, the use numberand frequency of large maintenance equipment can be reduced, the maintenance time can be reduced and the customer satisfaction can be enhanced; timely alarm can be performed, the inspection time can be reduced, the service life of the cable can be increased, the cable is ensured to maintain the great use state for a long time and the safe operation time of the cable can be increased; and when partial cables are in the high load state for a long time, the company can be prompted to replace the cables by the high power transmission capacity cables so that the accident probability can be reduced.

Description

technical field [0001] The invention belongs to the technical field of magnetic field positioning monitoring and alarming, and in particular relates to a magnetic field monitoring and alarming device for buried feeders and buried cables. Background technique [0002] The communication field equipment of the communication group company mainly includes pull rods, single-pipe towers, three-pipe towers, landscape towers, board-mounted antennas, RRU, wireless BTS equipment, wireless BBU equipment, transmission PTN equipment, communication feeders, communication cables, communication optical cables, etc. Power grid transmission facilities mainly include poles, transmission cables, insulators, etc. [0003] The buried feeder lines and buried cables of the communication group company have the characteristics of wide application range, long lines, and difficult troubleshooting of abnormal conditions. Once an abnormal situation occurs, such as feeder or cable damage, breakage, fusing...

AI Technical Summary

Problems solved by technology

Once an abnormal situation occurs, such as feeder or cable damage, breakage, fusing, etc., inspection personnel need to inspect for a long time and dig a lot of land to find the abnormal location. The excavation operation requires a lot of manpower and material resources, and the operation will affect regional traffic, Water supply and power supply have adverse effects, and long-term operation will affect the satisfaction of electricity customers and communication customers

[0004] At present, the maintenance of buried feeder lines and buried cables of Communication Group Corporation mainly relies on abnormal signal feedback from the control center and customer complaints to provide abnormal information, but neither of them can provide accurate accident location and abnormal situation information. When the length of the ground cable exceeds 2 kilometers, the maintenance needs to excavate a large area of ​​the ground, which is time-consuming and laborious. Obviously, there is currently a lack of a real-time monitoring, positioning and alarm system for the operation of buried feeders and buried cables
