Electricity approximation alarm method, device and electricity approximation alarm smart helmet

Abstract

The invention provides an electricity approximation alarm method, an electricity approximation alarm device and an electricity approximation alarm smart helmet. The method includes the following stepsthat: the position information map of a power inspection region is drawn in advance based on GPS and electric field sensor signals, and safety distances from position points in the power inspection region to corresponding field devices are pre-calculated; when power inspection is performed, the current position of a worker is determined on the basis of voltage signals of the position points and voltage signal change which is collected in real time by the electric field sensor signals; and if a distance from the current position of the worker to any device in the power inspection region is smaller than the pre-calculated safety distances, an alarm will be given. The device and smart helmet of the invention do not occupy a working space. With the method, device and smart helmet adopted, theGPS is adopted, and the safety distances of different devices can be set, and therefore, the problem of injuries and deaths caused by electric shocks in an electric power system can be solved.

Description

technical field [0001] The invention relates to the field of intelligent equipment, in particular to a near-electric alarm method and device, and a near-electric smart helmet. Background technique [0002] In high-voltage live work, electric workers often face the danger of electric shock, and the casualties caused by electric shock accidents have a bad impact on electric power industry every year. According to the statistical analysis of global accident data, approximately one person will die from electrocution for every 150 million kwh of electricity consumption. Through the analysis of the causes of electric shock casualties, the main cause of electric shock casualties is the accidental touch of live equipment, accounting for about 36% of the total number of electric shock casualties. The power industry brings huge economic losses and negative impacts. For front-line employees who have been working in power plants, transmission and distribution lines, and substations fo...

Problems solved by technology

Through the analysis of the causes of electric shock casualties, the main cause of electric shock casualties is the accidental touch of live equipment, accounting for about 36% of the total number of electric shock casualties. Huge economic loss and negative impact brought by electric power industry

For front-line employees who have been working in power plants, transmission and distribution lines, and substations for a long time, they have a higher probability of electric shock, especially when accidentally touching high-voltage live equipment, which usually causes death or serious injury to the workers event

[0003] In the early days, people mainly used insulating gloves and insulating rubber shoes as protective measures against induced electric shock. When the voltage level increased, the withstand voltage of ordinary insulating gloves and insulating rubber shoes no longer worked. And insulating rubber shoes are not used because they are heavy and affect normal work. As a result, there is currently no good way to deal with electric shock protection. In the substation inspection work, to prevent the electric shock accidents caused by front-line staff entering the charged interval by mistake, it is usually only through strengthening management to avoid the occurrence of such incidents, and there are no technical protective measures. Therefore, once an electric shock incident occurs, It will inevitably cause casualties of frontline workers

[0004] At present, through the continuous development of technology, the front-line staff will carry the near-electric alarm device when performing electrical operations. Although the near-electric alarm device can give the front-line staff some warnings to prevent electric shock to a certain extent, when the staff is working, The proximity alarm device it carries will not only occupy the hands or work space of the staff, but also bring a lot of inconvenience to the staff

[0005] In addition, there are many problems in the near-electrical alarm device, such as: 1. Lack of positioning system, unable to accurately locate the position of the front-line staff, resulting in the inability to quickly rescue in the event of an accident; 2. There is no setting for different voltage levels in the power inspection area The corresponding threshold value, or the anti-interference ability is poor, and it is easy to generate alarm errors, etc.
