Problems solved by technology
However, the configuration of the above-mentioned system mainly judges the status of the power grid based on the changes and abnormalities of electrical and chemical quantities. It can neither fully cover the substation nor provide real-time positioning and timely warning and alarm. Accident cause analysis provides a means of data record analysis, and it is impossible to prevent and warn of risk factors in advance. The safety of personal and equipment at the substation site has been affected by human factors such as personnel violations, chaotic on-site operations, inadequate on-site management, and inspections that do not follow regulations. Unable to obtain technical guarantees, resulting in the inability to avoid certain safety hazards based on human factors

Embodiment Construction
[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] The present invention is a method for eliminating potential safety hazards of personnel in substations, which consists of a rough positioning system, a fine positioning system, and a positioning monitoring system. The position information of on-site operators is captured by the coarse / fine positioning system and handed over to the positioning monitoring system for calculation. Operators are checked Whether the location is safe, if there is a person who violates the rules and crosses the border, the on-site warning device will give an alarm.
[0030] Concrete flow process of the present invention is as follows:
[0031] 1. Coarse positioning
[0032] The rough positioning system is realized by UWB positioning technology. The UWB positioning system is composed of positioning sensors and positioning tags (chip mode...

The invention relates to a method for eliminating safety hidden danger of substation personnel, comprising the following steps: (1) coarse positioning; (2) fine positioning; and (3) positioning monitoring. The method is of strong interactivity and high verisimilitude, is dynamic and flexible, has powerful functions, and is easy to use. There is no need to wear a complicated and heavy motion capture device, debugging registration is avoided, and the use and maintenance costs are reduced. The method is of high positioning accuracy and positioning frequency, can effectively prevent personal injury accidents caused by wrong operation and mistaken falling into an operation gap, greatly improves the safety, and eliminates safety hidden danger. Through positioning analysis and motion capture, the function of substation operating personnel positioning is achieved, and the positioning accuracy is less than 1mm. The operation action of operating personnel can be stored and recorded in the form of action sequence or video, which facilitates query and tracing.
Description
technical field [0001] The invention relates to a personnel positioning method, in particular to a method for eliminating potential safety hazards of substation personnel. Background technique [0002] As the foundation of the power grid, the substation is a high-risk work area for the production and operation of the power grid. Its operation safety management is particularly important. In order to improve the safety management level of the substation, in addition to formulating a series of regulations and systems, the management department also equipped the substation with an integrated automation system, a video surveillance system, a five-prevention system, and an online monitoring system for electrical equipment, etc. The above technical facilities have been greatly improved. It improves the automation level of the substation and provides certain technical support for the operation safety management of the substation. However, the configuration of the above-mentioned s...
