Feeder terminal control method based on image recognition on-pole switch state acquisition

Abstract

The invention relates to a feeder terminal control method based on image recognition on-pole switch state acquisition, and the method comprises the steps: arranging a camera at the front end of a pole-mounted switch, and enabling the camera to be connected with an FTU through a network cable and a power line; the camera transmits a picture shot in real time to the FTU through a network cable; an image and image information table of the pole-mounted switch in a normal state is pre-stored in the FTU memory; and after the FTU receives the current image, the current image is compared with the image stored in the FTU memory, so that the current working state of the pole-mounted switch is judged. According to the feeder terminal control method based on the image recognition column switch state acquisition, an FTU state acquisition board and a power board for providing a power supply for the state acquisition board are reduced, wiring of an aviation plug is reduced, the size and the cost of an FTU are reduced, and the reliability of column switch state acquisition is improved.

Description

technical field [0001] The invention relates to a method for collecting state quantities of switches on poles, in particular to a feeder terminal and a method for collecting state quantities of switches on poles based on image recognition. Background technique [0002] The method of traditional on-column switch status acquisition is to use the voltage generated by the travel switch placed inside the on-column switch (state acquisition loop on and off) to judge The current state of the ring main unit, its state quantity includes the opening and closing position of the switch, the energy storage state, the position of the isolation knife switch, etc. The acquisition of state quantities requires the power supply of the state acquisition loop provided by the feeder terminal (hereinafter referred to as FTU). Since the state quantities collected by the switch on the pole need to be connected to the FTU with an aviation plug, not only the wiring is complicated and error-prone, but ...

AI Technical Summary

Problems solved by technology

The acquisition of state quantities requires the power supply of the state acquisition loop provided by the feeder terminal (hereinafter referred to as FTU). Since the state quantities collected by the switch on the pole need to be connected to the FTU with an aviation plug, not only the wiring is complicated and error-prone, but the long transmission distance leads to the attenuation of the state quantity signal , it is easy to mis-collect and miss-collect, and when the power supply of the FTU and the switch state collection circuit on the column is interrupted, the FTU cannot collect the state, which will lead to the collapse of the entire monitoring system and seriously affect the fault judgment and fault isolation. In this case, the power supply reliability no guarantee
