On-line touring system of power transmission line
2013
The invention discloses an on-line touring system of a power transmission line. The on-line system comprises an optical fiber communication subsystem, a backstage monitoring host subsystem and tower terminal subsystems which are arranged on towers one by one. Each tower terminal subsystem comprises a measuring unit, a terminal host, an energy supply unit and an optical network unit. The measuring units are used for collecting monitoring data in a power transmission circuit. The terminal hosts are used for finishing converging, pretreating and uploading of the monitoring data and receiving an order sent by the backstage monitoring host subsystem to control all the units. The energy supply units are used for providing energy for the measuring units and optical network unit devices through relay exits of the terminal hosts. The monitoring data collected by the tower terminal subsystems of all the towers are connected with the optical units through the optical network units, wherein the optical units are continuously led downwards from all the towers, and the monitoring data are connected into the optical fiber communication subsystem. The backstage monitoring host subsystem has the functions of storing the monitoring data, analyzing, inquiring, alarming and the like and is communicated with all the tower terminal subsystems through the optical fiber communication system.
