Description
Technical field
The invention belongs to monitoring field, particularly relate to a kind of long distance control system for transmission line of electricity.
Background technology
Be dispersed with 220kV and above transmission line of electricity more than 4000 kilometer at present in Shanghai, the thousands of base of steel tower, and inner city, Shanghai Urban concentrate and power load is high, to power supply reliability require also improving constantly, power grid operation faces huge challenge.
Transmission line status plays vital effect to power grid security, in recent years, the monitoring technology of converting equipment becomes better and approaching perfection day by day, status monitoring means reach its maturity, and transmission line of electricity is still in comparatively extensive supervisor status, be difficult to tackle the reliability requirement day by day improved, more cannot meet the needs of intelligent grid development.
Traditional video monitoring system is simple non intelligent closed-circuit television system, its shortcoming is fairly obvious, such system or need Security Personnel's real time monitoring picture to catch critical event, or need carrying out playback to videograph afterwards and carrying out manual analysis, take time and effort, cost is high and efficiency is low.
At present in the transmission line of electricity of District of Shanghai topmost outside destroy hidden danger have two kinds, wherein big machinery vehicle is operated against regulations in circuit protected location, and arm easily touches line and causes trip accident, is one of main outside destroy hidden danger of ultra-high-tension power transmission line; Another is the hanger such as kite, waterproof cloth, is suspended on transmission line of electricity, under rain, snow weather, causes insulation between circuit to decline, causes trip accident.
These accidents gently then cause large-area power-cuts, cause serious economic loss, heavy then cause casualties.Traditional manual patrol mode is difficult to provide alert and alarm to the danger appeared at around circuit and on steel tower in time, the demand for security of building strong intelligent grid can not be met, therefore, the remote wireless video monitoring technique of anti-outside destroy carries out early warning and monitoring to outside destroy transmission line of electricity or shaft tower itself and is significant.
Vision signal is sent to Surveillance center by the 3G wireless communication technique that utilizes of current appearance; Intelligent Recognition is carried out in Surveillance center; early warning signal is sent in time there is outside destroy hidden danger; and pass signal back scene again; realizing local sound and light alarm to monitor the technology in line protection district, there is following problem in it:
1. the bandwidth of current 3G WCDMA wireless network, cannot meet the transmission to HD video data, make the identification at background monitoring center and the poor effect of process, especially lower to the discrimination of the hanger that kite/waterproof cloth equal-volume is little, transparency is high;
2. according to the sharpness of CF, the data transmission of 10 ~ 15 frames/second, wireless telecommunications flow exceed the 15G/ month, and wireless telecommunications expense is huge, are difficult to large-scale promotion;
In sum, prior art cannot meet current monitoring in real time transmission line of electricity and demand to the timely early warning of relevant external force hidden danger.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of transmission line long-distance based on DSP pre-process intelligence and instead damages supervisory system outward, it is when transmission line of electricity field condition is normal, not to backstage Surveillance center transmission data, when there is damage hidden danger in scene, preposition terminal will identify the type of hidden danger by DSP, real time video signals is passed back to background monitoring center to report to the police and record, and at local sound and light alarm; Its preposition terminal stores 12 hours to video image, and to the Video Image Marker time stored, is set to unsuppressible-suppression to the video image that the damage hidden danger time period occurs; Background monitoring center has the function of any road image in prison control point far away being carried out to monitoring in real time.
Technical scheme of the present invention is: provide a kind of transmission line long-distance based on DSP pre-process intelligence instead to damage supervisory system outward; it is characterized in that: described supervisory system is to the damage dangerous matter sources occurred in line protection region; comprise the hanger such as big machinery vehicle, kite/waterproof cloth; carry out automatic real time kinematics detection and tracking; and multistage early warning is carried out to the potential danger that dangerous matter sources may cause transmission line of electricity, its concrete steps comprise:
