Environment monitoring and safety early warning system of transmission line

Abstract

The invention discloses an environment monitoring and safety early warning system of a transmission line. The system comprises a plurality of on-site monitoring terminals arranged at a transmission line electric pole. The plurality of on-site monitoring terminals are connected with a database server through a GPRS network; and the database server is connected with a plurality of clients. The on-site monitoring terminals include main controllers, signal conditioning modules, GPS modules, interaction modules, power modules, storage modules, and GPRS communication modules, wherein the signal conditioning modules, the GPS modules, the interaction modules, the power modules, the storage modules, and the GPRS communication modules are connected with the main controllers electrically; and the input terminals of the signal conditioning modules are connected to environmental sensors, weather sensors, tilt sensors, and infrared cameras. According to the invention, with a wireless GSM / GPRS / CDMA transmission mode, environment and weather parameters and the like of the transmission line are monitored in real time; and early warning of the abnormal condition of the line is provided. The GPS module can locate the position information of the monitored line segment in real time. When a fault occurs at the line, positioning is performed rapidly and field repairing is performed, so that the emergency disposal efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of electric power technology, in particular to an environmental monitoring and safety early warning system for transmission lines. Background technique: [0002] With the rapid development of social economy, all walks of life have put forward higher requirements for the quality and quantity of power supply. Due to the uncertainty of the environment of the transmission line in the power grid, whether the line operation is safe has become a part of the reliability of the power grid. an important indicator. [0003] Since transmission lines extend tens or even hundreds of kilometers vertically and horizontally, they are in different environments. Therefore, high-voltage transmission lines are greatly affected by the geographical environment and climate, and line failures are easily caused by floods, snowstorms, wind deviation, lightning strikes, pollution, etc. In particular, timely grasp of changes in the local enviro...

Problems solved by technology

[0004] Traditional high-voltage transmission line monitoring adopts inspection methods, mainly in two types, namely, manual visual inspection and helicopter aerial survey: manual visual inspection involves inspectors patrolling tower by tower along the ground, and sometimes it is necessary to board The iron tower or the pulley suspended on the line, this kind of operation method has low precision, high labor intensity, high cost, long cycle, high risk, and there are inspection blind spots

The helicopter aerial survey method is to drive a helicopter to inspect along the line, and use cameras and other non-contact detection technologies to inspect the line. This method has the advantages of strong flexibility and wide field of vision, but there are hidden dangers to flight safety and cost expensive

Due to the many deficiencies in the above inspection operation methods, the power sector urgently needs equipment that replaces or assists manpower in line inspections
