Description
Technical field
The utility model relates to a kind of windage yaw detection system of processing based on image, belongs to the ultra-high-tension power transmission line field.
Background technology
Along with developing rapidly and the rapid expansion of scale of national grid, increasing transmission line of electricity is had to by the landform of complexity and the adverse weather condition area is arranged, the phenomenon day by day of windage yaw tripping operation.Most of windage yaw tripping operations all occur under operating voltage, reclosing rate low (25% left and right), and this will cause large area blackout, have a strong impact on for electrical stability and reliability, cause larger harm for the operation of electrical network.When the windage yaw tripping operation occurs, usually with strong wind and thunderstorm weather, be difficult in time judgement and looking up the fault point, bring certain difficulty for the maintenance of circuit.Therefore, the monitoring at power transmission circuit caused by windage angle seemed particularly important.
At present, two kinds of methods of the general employing of detection to the insulator chain angle of wind deflection, a kind of is to measure by mounted angle sensor on insulator chain, the method can only be with installation of sensors at not charged position, insulator chain top when sensor installation, when just bottom insulator side-play amount is very large, and insulator chain not near shaft tower (and the windage yaw discharge does not occur), will cause wrong report at this moment, is difficult to accurate early warning; Another kind is by parameters such as near the wind speed the measurement insulator chain, wind direction, temperature, humidity, utilize the angle of wind deflection computing formula to calculate angle of wind deflection, the method is subjected to the restriction of sensor accuracy and selected mathematical model, and mathematical model can not all be considered the various parameters that affect windage yaw detailed fully, has certain error.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of windage yaw detection system of processing based on image, has greatly improved stability and the reliability of transmission line of electricity, has made up the deficiency of existing windage yaw pick-up unit.
This utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
Windage yaw detection system based on image is processed comprises video collector, power supply, video compressor, image processor, mobile module and Background control terminal; Described power supply is connected with described video collector, video compressor, mobile module respectively; Described video collector is connected successively with described video compressor, image processor, mobile module, and described video collector is the CMOS camera that is arranged on shaft tower; Described mobile module is connected with described Background control terminal by network
The beneficial effects of the utility model are: this windage yaw detection system principle simply, intuitively easily row, detection reliably, from characteristic matching measurement insulator chain angle of wind deflection, have improved stability and the reliability of transmission line of electricity greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described.
As shown in Figure 1, power supply 3 is video collector 1, video compressor 2 and mobile module power supply.Video collector 1 is the CMOS camera, is used for gathering the coloured image of transmission circuit insulator string, by video compressor 2, the coloured image that collects is compressed packing and processes, and reduces data volume; Image processor is the microprocessor based on Hough transformation, adopt the chip of prior art both can realize, be used for the image of video compressing module 2 compression packings is carried out filtering, image gray processing, inter-frame difference and generalised Hough transform processing, insulator chain is carried out characteristic matching, and the position that matches insulator chain also accurately calculates the angle of wind deflection of insulator chain.Mobile module 5 is sent to the Internet network with the video data of insulator chain and the angle of wind deflection result after processing by 3G network, and Background control terminal 6 is computing machine, receives by the Internet network data that mobile module 5 sends.By Background control terminal 6, we can observe present situation and the angle of wind deflection of insulator chain intuitively.
Principle: at first, by the digital video image of the data acquisition module Real-time Collection insulator chain on shaft tower; Data processing module is sent to the Internet network with the video data compression packing that gathers by 3G network; The Background control center receives by the Internet network and sends the video data of returning, and video data is filtered unchangeability generalised Hough transform image process, and accurately calculates the angle of wind deflection size of insulator chain.
Simple, the directly perceived easily row of a kind of windage yaw detection system principle based on the image processing, the detection that the utility model proposes are reliable, measure the insulator chain angle of wind deflection from characteristic matching, have greatly improved stability and the reliability of transmission line of electricity.
