Description
Technical field
The present invention relates to a kind of for ultra-high-tension power transmission line on-Line Monitor Device (as video monitoring apparatus, high voltage transmission lineRoad temperature monitor, weather monitoring instrument) signal transmission system. This system is applicable to be arranged on and has inconvenient traffic, communication is smooth, inclined to one sideUnmanned area far away, for ultra-high-tension power transmission line on-Line Monitor Device provides signal transmission.
Background technology
At present, the tour of high-tension line is normally completed by people, generally monthly carries out once customary tour. For trafficWith the area of communication inconvenience, line walking operation irregularity difficulty. Domestic on-Line Monitor Device is only for transformer station or power plant etc.There is communication network to cover and have the place of low-tension supply. Although also there is the 3G of use wireless network camera to carry out remote video transmission, but its limited bandwidth, and cannot be used for the area that does not have wireless network signal to cover. " a kind of operation absolutely for Chinese invention patentEdge on-line real time monitoring system " (patent No. 02151623.5) related to the transmission of vision signal, but transmission means makesWith radio, need to there iing the ground that receives base station can realize just now remote transmission. Although the international monopoly KR100820287 of Korea SRelate to video monitoring and the signal transmission of ultra-high-tension power transmission line, but the transmission of the signal of this patent is used electric line carrier communication,Bandwidth is very limited, and electric line carrier communication equipment investment is large. Therefore, in global range, be not yet applicable to without communication at presentHaving inconvenient traffic or the signal transmission system of the ultra-high-tension power transmission line on-Line Monitor Device in unmanned area of the network coverage.
Summary of the invention
At present, the tour of ultra-high-tension power transmission line is normally completed by people, different in the line walking work in remote districts and mountain areaNormal difficulty. Adopt the automated machine line walkings such as unmanned aerial vehicle unreliable, and service range is limited, cost is high, be subject to weather and environmentImpact is large. Adopt the camera of 3G wireless network signal transmission to be also subject to bandwidth, signal cover and without low-tension supply supplyRestriction, cannot be used for remote districts. The invention provides a kind of signal transmission solution party of ultra-high-tension power transmission line on-Line Monitor DeviceCase. Monitoring equipment comprises as video monitoring apparatus, ultra-high-tension power transmission line temperature monitor, weather monitoring instrument. This scheme has solvedThe problem of remote districts ultra-high-tension power transmission line line walking difficulty, can be in the area that has inconvenient traffic, do not have cordless communication network to cover, rightMonitoring equipment carries out signal transmission, realizes the remote monitoring to these regional ultra-high-tension power transmission lines, reduces track walker'sWorkload.
The technical solution adopted for the present invention to solve the technical problems is: all kinds of monitoring equipments, and as video monitoring apparatus, heightPressure transmission line temperature monitor, weather monitoring instrument, and signal transmission apparatus, as electrical to optical converter and wireless network transmitter,All be arranged on high-tension line. The signal of monitoring equipment is converted to after data signal, and carry out electric light conversion and become laser signal,Export by optical fiber. Optical signal is propagated by any one mode below:
One, optical fiber is around overlaying on ultra-high-tension power transmission line, extend to nearest, in earthy optical cable connecting box(as the splice tray of composite cable ground wire (OPGW) or All Dielectric self-support (ADSS)) located; Again will be in height by insulatorThe optical fiber of the current potential that pressure transmission line is identical is connected in earthy splice tray. Signal directly passes through ultra-high-tension power transmission lineUpper existing composite cable ground wire (OPGW) or All Dielectric self-support (ADSS) optical fiber, long-distance transmissions is to Surveillance center.
Two, optical fiber is around overlaying on ultra-high-tension power transmission line, extend to nearest, have low-tension supply and communication network to coverArea, through after electric light conversion, data signal is accessed to wireless router, (wireless such as IEEE802.11 by wireless networkHost-host protocol) be transferred to the signal relay center on ground. Wireless router and electrical to optical converter are arranged on ultra-high-tension power transmission line;The relay center on ground is powered by low-tension supply, and signal transmission is by wired or wireless Internet Transmission.
The beneficial effect of patent of the present invention is, having inconvenient traffic, unmanned, without communication network cover, without natures such as low-tension suppliesThe area of inclement condition, allow the application of ultra-high-tension power transmission line on-line monitoring system become possibility, realizes remote monitoring systemLarge capacity data acquisition and transmission. Fiber optic communication realizes high bandwidth, transmits the advantages such as far away, anti-interference. The design of this system meetsThe requirement of intelligent grid to ultra-high-tension power transmission line remote real time monitoring. Finally reach on the basis that does not increase plant maintenance workloadUpper, reduce track walker's workload, realize round-the-clock real-time remote monitoring.
