Abstract

The invention discloses an online monitoring device suitable for long span integrated monitoring. The online monitoring device comprises a sensor system, a communication system, a master control system and a power source system, wherein the master control system comprises a master control plate, a data collection plate, a storage unit and an interface; the sensor system comprises an aeolian vibration monitoring intelligent sensor, a wire temperature measurement intelligent sensor, a weather intelligent sensor, a filth monitoring intelligent sensor and a webdome; the communication system comprises an IP (Internet Protocol) module, a GPRS (General Packet Radio Service) communication module, a 3G communication module and an RF (Radio Frequency) module; the power source system adopts the modes of 220 V mains supply and a back-up storage battery and the modes of a self-provided solar panel and an energy storage battery, and is directly connected with the master control plate. According to the online monitoring device, multiterm state monitoring is uniformly processed, online integrated monitoring is conveniently and accurately performed on a long span line section with a special operating environment, line operation and maintenance personnel are reminded of taking measures in time, accidents of tripping operation, disconnection, tower collapse and the like are prevented as early as possible, and heavy loss is avoided.

Description

technical field [0001] The invention belongs to the technical field of transmission line on-line monitoring technology, and in particular relates to a comprehensive on-line monitoring device for digitizing, visually monitoring and managing the state of a large-span transmission line section with special geographical environment or micro-meteorological characteristics. Background technique [0002] The large span of the line is an important part of the transmission line, and it has a special important position in the operation of the line. Once a fault occurs, it will seriously affect the safe and stable operation of the entire power system. In view of the special geographical environment and micro-meteorological characteristics of large spans, high suspension points and open waters, etc., the existing transmission line condition monitoring technology is fully utilized, and advanced condition monitoring methods and technologies are used as supplements to achieve large-scale T...

Problems solved by technology

[0003] The content of transmission line status monitoring mainly includes: wire breeze vibration monitoring, wire temperature monitoring, wire sag monitoring, micro meteorological parameter monitoring, on-site pollution degree monitoring, video image monitoring, tower tilt monitoring, line equivalent ice thickness monitoring, wind However, most of the current transmission line status monitoring adopts a single monitoring method, that is, a set of online monitoring devices only realize a single monitoring function, which is suitable for most of the online monitoring needs of transmission lines, because often a certain The monitoring requirements required by a monitoring point are relatively simple

However, for special occasions such as large crossings of the line, due to factors such as its special geographical location, large spans, high pole towers, crossings with the water surface, and difficulty in maintenance and detection when faults occur, it is often necessary to carry out multi-functional inspections on the site. Monitoring, focusing on the monitoring of wind vibration of ground wires, sag of ground wires, pollution of insulator strings, micro-meteorology, video images, tower tilt, wind deflection of wires and insulator strings, etc. If a single monitoring method is used, it is necessary to install multiple sets For monitoring devices, each device is set separately and managed independently, which often leads to a series of problems such as inability to share information, heavy maintenance and management workload, high cost, and low reliability. Therefore, it is necessary to develop a condition monitoring device that can realize multi-functional monitoring. To meet the actual needs of large-scale comprehensive online monitoring
