Description

technical field [0001] The invention belongs to the technical field of positioning, and relates to a personnel positioning device based on a GPRS mobile terminal. Background technique [0002] Electricity has become the most important energy source in our country and is closely related to people's production and life. The power transmission and distribution system is an important part of the power grid. [0003] The maintenance and repair of power transmission and distribution equipment is an important guarantee for the normal operation of the power grid. Its characteristics are that it must be fixed accurately and repaired in time. Therefore, for equipment maintenance and fault monitoring, large-scale power grid systems often have an independent power communication intranet. [0004] At present, the maintenance and repair mode of large-scale power grids is usually that the monitoring center detects and locates faults in the network, and then contacts the staff to go for m...

AI Technical Summary

Problems solved by technology

[0005] Undoubtedly, the current personnel positioning method is very primitive and basically cannot meet the needs of maintenance and repair of equipment or power grids

[0006] In addition, the personnel positioning devices currently on the market are relatively large in size, which is very inconvenient to install, wear, and maintain, and the positioning accuracy is not high
