Terminal self-adaption method in personnel positioning system and system thereof

Abstract

The invention discloses a terminal self-adaption method in a personnel positioning system and a system thereof. The terminal self-adaption method comprises a rate self-adaption method, wherein the rate self-adaption method comprises the following steps of: S1, searching beacon information by a portable terminal; S2, determining a transmission rate according to the beacon information; and S3, sending the message containing the beacon information to the gateway at the transmission rate determined in the step S2. The portable terminal can adapt to the transmission rate according to the characteristics of the position where the portable terminal is located, the positioning distance of the positioning system is increased, the positioning precision of the system is guaranteed, the arrangement cost of the gateway can be reduced and the system performance can be optimized to the maximum extent while the requirements of all areas are met, and the method has obvious advantages compared with a fixed-rate scheme in the prior art.

Description

technical field [0001] The invention belongs to the technical field of personnel positioning, and in particular relates to a terminal self-adaptation method in a personnel positioning system and a system thereof. Background technique [0002] The basic structure of the traditional personnel positioning system is fixed deployment of positioning base stations, personnel carry positioning tags, and the positioning base station receives information from the positioning tags carried by personnel, and performs identification and positioning according to its field strength, phase, tag serial code and other information. This architecture has disadvantages such as complex system, complex positioning and easy environmental impact on positioning accuracy. [0003] In order to solve the above technical problems, people have carried out long-term exploration, such as a personnel positioning system disclosed in a Chinese patent [application number: CN201310684121.8], including a personnel...

Problems solved by technology

However, the above scheme still has obvious shortcomings. For example, the above-mentioned personnel positioning system is not flexible enough, and the portable terminal sends messages to the gateway in the same way no matter where it is. However, in practical applications, the area of ​​a positioning system usually includes multiple Areas with different characteristics, some areas are vast but have less traffic (such as automated workshops), and some areas have relatively large traffic and high busyness (such as public office areas, conference rooms, etc.). In addition, a positioning system may span Several remote areas, such as construction sites and office areas, users walk back and forth in these areas with different levels of busyness. If the low-speed transmission mode is fixed, it will cause message conflicts and network congestion in high-busy areas. Fixed high-speed transmission mode will result in the inability to achieve precise positioning in a wide range of areas, and more gateways must be used, which will lead to a substantial increase in costs. The larger the system coverage area, the greater the cost increase

In order to solve the aforementioned problems, some companies have thought of adopting a compromise medium-speed transmission method, but this method cannot achieve the best results to the greatest extent.
