Technical Field
[0001] The invention relates to the technical field of power system operation, and in particular to a switching operation double confirmation method based on manual remote confirmation. Background Art
[0002] In the field of power system operation technology, switching operation is an important task, which involves the switching of the operating status of the power system, including the opening and closing of circuit breakers, the opening and closing of disconnectors, etc. In order to ensure the safety and accuracy of the operation, the switching operation requires strict double confirmation, that is, confirmation is required before and after the operation. In addition, with the development of remote control technology, more and more switching operations are beginning to be carried out by remote control to improve the efficiency and convenience of operation.
[0003] In the existing technology, the double confirmation of the switching operation is usually confirmed by the remote signal position + micro switch position or video recognition. The micro switch is a precision electrical switch that can generate an electrical signal when subjected to external force, thereby realizing the detection and confirmation of the equipment status. Video recognition is achieved by adding video monitoring to the equipment position observation window and using image processing technology to identify simple graphic changes to complete the confirmation. In actual operation, the operating system can determine whether the equipment is in the correct state through the remote signal status and micro switch or video recognition.
[0004] However, the accuracy of the micro switch is limited, and misjudgment may occur, thus affecting the accuracy of the operation. Secondly, the reliability of the micro switch is insufficient. The vibration generated by the separation and combination of the equipment may cause the micro switch to deform or displace, thereby causing the micro switch to become stuck or damaged, thus affecting the accuracy and safety of the operation. Video recognition itself is not reliable and is more susceptible to interference from environmental factors. Video recognition is used at every device location, which greatly increases the economic cost of equipment operation. Therefore, both micro switches and video recognition have defects and disadvantages, which increase the risk of operation. Summary of the invention
[0005] The purpose of the present invention is to provide a double confirmation method for switching operation based on manual remote confirmation, so as to solve the technical problems proposed in the above background technology that the micro switch has limited accuracy and may affect the accuracy of operation; the video recognition reliability is insufficient and is easily affected by environmental factors; the micro switch maintenance is time-consuming and labor-intensive, and is prone to human errors; and the video equipment increases the operating costs.

Keep the signals between the operating host and the device synchronized in real time.
[0010] Preferably, in step S4, the step of confirming whether the status is consistent with the status displayed on the repeater and remotely transmitting the actual status on site back to the operating host comprises the following steps; S41.

If the telesignal signal is inconsistent or the repeater confirmation signal is not received within a certain period of time, the operation will be interrupted immediately, the fault handling process will be started, and an alarm will be issued to the operator.
