Personnel positioning device based on WiFi mobile terminal

Abstract

The invention discloses a personnel positioning apparatus based on a WiFi mobile terminal. The personnel positioning apparatus based on a WiFi mobile terminal is mainly formed by an RTK (Real-time kinematic) difference base station and a WiFi mobile terminal, wherein the RTK difference base station mainly includes an RTK difference positioning module, an MCU1, a WiFi module 1, a GPRS (General Packet Radio Service) module, an MEMS (Micro-Electro Mechanical System) inertial navigation module 1, an ethernet port module, and a power supply module; the RTK difference positioning module, the WiFi module 1, the GPRS module, the MEMS inertial navigation module 1, the ethernet port module, and the power supply module are connected with the MCU1; the RTK difference positioning module is connected with the GPRS module; the WiFi mobile terminal mainly includes a GPS positioning module, an MCU2, a WiFi module 2, an MEMS inertial navigation module 2 and a lithium battery power supply module; the GPS positioning module, the WiFi module 2, the MEMS inertial navigation module 2 and the lithium battery power supply module are connected with the MCU2; and the GPS positioning module is connected with the WiFi module 2. The personnel positioning apparatus based on a WiFi mobile terminal integrates a high precision satellite positioning technology with a data transmission technology and utilizes an integrated circuit technology, so that high precision and miniaturization of the personnel positioning apparatus can be realized, and can satisfy the requirement for portability of equipment, and accuracy and timeliness for personnel positioning.

Description

technical field [0001] The invention belongs to the technical field of positioning, and relates to a personnel positioning device based on a WiFi 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
