Positioning terminal and positioning method based on wireless communication technology

Abstract

The invention relates to the technical field of wireless communication, and in particular relates to a positioning terminal and a positioning method based on a wireless communication technology. The positioning process of the positioning method disclosed by the invention comprises the following steps: detecting the wireless beacon frame emitted by a wireless beacon at the position of the location through the positioning communication terminal, and sending out the detected wireless beacon frame; calculating the position of the positioning communication terminal. According to the positioning terminal and the positioning method disclosed by the invention, balance in the various aspects of capacity, power consumption, efficiency and the like is realized; the position wireless beacon only needs to periodically send signals, and the operation is simple; the positioning communication terminal does not need to temporarily break away from a network, the continuity of communication can be kept, the consumption of a battery is reduced, and the deployment amount of a mobile base station can be reduced; terminal time is uniformized through a time server, thus the terminal can delay reporting without losing location information, and can reduce reporting times.

Description

technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a positioning terminal and method based on wireless communication technology. Background technique [0002] Communication technology is changing with each passing day, especially wireless communication technology, which is particularly important in today's period of rapid development of the information industry. The application of wireless communication technology has naturally become an important direction of scientific and technological development. Among them, the use of wireless communication for positioning is an important application now and even in the future. [0003] For example, in the process of underground operations, in the exploration process, etc., positioning is required. However, in the above-mentioned special environment, no matter the technology used or the maintenance work in the future, many difficulties will often be encountered, and ...

AI Technical Summary

Problems solved by technology

However, PHS and Wifi will be limited due to the base station capacity when there are many people at the same time.

And when the positioning communication terminal detects the field strength of the surrounding base stations, it needs to leave the network temporarily, and the communication function is interrupted, which has hidden dangers to production management and safety management

At the same time, in the continuous positioning state, the power consumption of the positioning communication terminal increases, and the working time of the battery is limited

[0007] The Chinese patent application No. 200710119139.8 discloses an underground positioning system and method. Although a wireless beacon is used, the beacon only broadcasts the node identification, and the accuracy cannot be guaranteed during the positioning process, and the system cannot realize multi-base station positioning.

The positioning terminals are not synchronized in time. When the number of terminals is large, the wireless channel is frequently occupied

In addition, since its wireless communication base stations participate in positioning detection and other related actions, it is bound to affect communication functions or increase power consumption due to matters such as detecting the field strength of surrounding base stations.
