Description

Technical Field

[0001] The present invention relates to the technical field of live working, and in particular to an AR-based live working system with a mechanical monitoring function. Background Art

[0002] With the continuous development of the economy and the improvement of people's living standards, the requirements for the reliability and availability of power supply of the power grid are getting higher and higher. The power grid operation mode has changed from the traditional "power outage operation as the main and live operation as the auxiliary" to "non-stop operation". In non-stop operation, the insulation performance of insulating tools, the mechanical properties of load-bearing tools, and the safe distance during operation are the key to ensure the safe implementation of the operation. When the operating equipment is damaged or overloaded, if it is not discovered in time, it will cause accidents to personnel or equipment.

[0003] At present, power grid companies mainly conduct mechanical tests on non-stop working tools on a regular basis. The test cycle is once a year for insulating tools and once every two years for metal tools. During the non-mechanical test period, the non-stop working tools can only be judged by appearance inspection to see if they are good. At the same time, in the early stage of the operation, the line ledger data is collected and the corresponding model of non-stop working tools is selected according to the calculation results. However, the appearance inspection has poor accuracy. During the non-mechanical test period, it is difficult to ensure whether the non-stop working tools meet the operation requirements, which is easy to cause accidents. In addition, the ledger data is often inaccurate. If the calculated value in the early stage does not match the site, the model of the non-stop working tool selected is incorrect, which will also increase the safety hazards during the operation.

[0004] At the same time, the operators are not familiar with the performance and technical parameters of the selected non-stop working tools, and it is easy for them to exceed the allowable load of the working tools during use, leading to accidents.

[0005] In addition, when working with live electricity, workers must wear insulating gloves, so they cannot debug the equipment through touch screens, buttons, etc., making it difficult to achieve human-computer interaction. Summary of the invention
