Embodiment Construction

[0019] The technical solution of the invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the real-time video status monitoring system for transmission lines based on wireless communication includes several front-end monitoring devices installed on transmission line towers, as well as communication modules and power supply modules connected to the front-end monitoring devices. The ground line OPGW optical fiber and the wireless metropolitan area network 802.16 protocol method transmit the collected image and video information to the communication base station, and the communication base station transmits this information to the system server. Remotely control the rotation and focal length of the camera to view the status of the transmission line from an appropriate angle, so as to achieve real-time monitoring of the video status of the transmission line.

[0021] The front-end imag...

Abstract

The invention discloses an electric transmission line real-time video condition monitoring system based on wireless communication. The system comprises a plurality of front end monitoring devices, a communication module and a power supply module, the front end monitoring devices are installed on electric transmission line poles and towers, the communication module and the power supply module are connected with the front end monitoring devices, the front end monitoring devices transmit image video information collected through an optical ground wire (OPGW) optical fiber and a wireless metropolitan area network 802.16 protocol to a communication base station, the communication base station transmits the information to a system server, the server checks and browses a current real-time monitoring state through a client, and transmission line states are checked through rotation and focal distances of a pan-tilt remote control camera, so that electric transmission line video states are real-timely monitored. The system uses the OPGW optical fiber for transmission so that the network bandwidth is large and safety is high; and a wireless metropolitan area network technology is used for performing wireless extension so that the system can be used in mountain areas, and the system has the advantages of being high in safety, comprehensiveness, real-time performance and adaptive capacity.

Description

technical field [0001] The invention belongs to the field of power transmission line monitoring, and in particular relates to a real-time video state monitoring system for power transmission lines based on wireless communication. Background technique [0002] The transmission network covers a vast area, has complex geography, harsh operating environment, difficult line inspection, and heavy maintenance workload. From the blackouts in Europe and the United States in recent years to the rare ice and snow disaster in southern China in 2008, it has proved the importance of transmission lines and the fragility of transmission networks. Just because some problems will occur during the operation of the transmission line, the line inspection method is adopted for the transmission line in order to grasp the status of the line operation and find equipment defects and hidden dangers in time. However, the current operation and maintenance methods of transmission lines still mostly adop...
