On-line cable line monitoring system based on all-in-one sensor

The invention relates to an on-line cable line monitoring system based on an all-in-one sensor. The on-line cable line monitoring system is established on the basis of a wireless private-network transmission environment, an on-site wireless sensing technology, a front communication machine and master station software and consists of an on-site collection and transmission system, a special GPRS (general packet radio service) communication network, a master station server and master station software. The on-line cable line monitoring system based on the all-in-one sensor can guarantee that operation parameters of an outdoor ring main unit cable line are uploaded inerrably, stably and safely and system equipment failure is positioned accurately, can collect states and parameters of a cable during on-line operation in real time, can finish data arrangement and sorting storage, and can automatically analyze data change and alarm in real time; and through analysis for long-term on-line monitoring operation data, equipment running state change can be summarized, and data support is provided for state maintenance.
