Positioning device and system

Abstract

The invention relates to a positioning device and system. The positioning device is applied to main positioning equipment and comprises a first inertial navigation sensor, a first communication module, a human-computer interaction module and a first processing module, the first inertial navigation sensor, the first communication module and the man-machine interaction module are respectively connected with the first processing module; the first inertial navigation sensor is used for acquiring a deflection angle and an acceleration of the main positioning equipment; the first communication module is used for receiving first position information, sent by slave positioning equipment, of the slave positioning equipment; and the first processing module is used for acquiring second position information of the main positioning equipment according to the deflection angle and the acceleration, acquiring a relative position between the main positioning equipment and the slave positioning equipment according to the first position information and the second position information, and controlling the man-machine interaction module to output prompt information according to the relative position. According to the embodiment of the invention, not only can the positioning precision be improved, but also the positioning blind area can be avoided.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning device and system. Background technique [0002] In areas such as train stations, airports, shopping malls, hot spots and other areas with a large flow of people and unfamiliar and complex environments, accidents of people getting lost are very prone to occur, especially for the elderly, children and disabled people. In related technologies, anti-lost products are mainly divided into two categories, one type of product is a traction rope product, such as a child anti-lost traction rope. The specific method of use is to use traction rope products to connect people who are easy to get lost with equipment such as elastic ropes and straps and guardians. This method mainly has two shortcoming, and the one, tripping and stepping on easily take place in crowded and complex terrain, and the 2nd, traction rope is easily untied and loses its effect, and practical...

AI Technical Summary

Problems solved by technology

Although the positioning electronic equipment adopts wireless positioning technology, it can avoid the above-mentioned tripping and trampling situations, but the accuracy of civilian GPS is about 10m, and in crowded places such as railway stations, large shopping malls, etc., the distance is often shorter It is easy for people to get lost

At this time, the positioning accuracy of GPS cannot meet the accuracy requirements for personnel positioning or personnel search.

Moreover, positioning cannot be performed in areas with weak GPS signal coverage or no GPS signal coverage, and the practicability is poor
