Abstract： In this paper， a position discrimination system based on machine vision sensing is designed to accurately identify the opening and closing status of the disconnector， and a non-homologous position "double confirmation" criterion is formed by realizing the opening and closing position of the disconnector with the traditional auxiliary switch contacts， which provid auxiliary discrimination support for one-key sequential operation， at the same time， a retrofit scheme is designed for the discrimination of the opening and closing positions of the existing isolating switches in the substation. The field operation shows that the system designed in this paper has good stability， accuracy and reliability， which plays a certain role in promoting the implementation of one-key sequence control technology.

国内高压隔离开关位置常采用遥控信号及现场人工观测判断分合是否到位[1-2]，这种方法容易受到观测者的主观影响，工作效率低。对于无人值守站来说，遥控操作现场通常无法进行人工确认。目前，一些站采用图像识别、压力传感等方法辅助判断隔离开关位置状态，但上述位置监测方法在稳定性、准确性及适应性等方面仍存在较多问题，例如，压力传感法设备安装困难、无法实现不停电部署及更换，微动开关法触头易磨损、氧化。现有隔离开关分合闸位置监测方法具有一定的局限性，人们需要寻找新的技术方法和技术手段，实现分合闸位置的精确判断。

随着科学技术的不断发展，机器视觉及人工智能技术不断取得突破，其在交通、安防、无人机、机器人和虚拟现实等领域广泛应用，表现卓越，为隔离开关分合闸位置判别提供了一种新的重要思路。……
