Bluetooth positioning message delivery and guidance system

Abstract

The invention relates to a bluetooth positioning message delivery and guidance system applied to bluetooth equipment. Position and status of an object are known under a control environment, position changes are learnt, operation of message exchange is carried out through the system, and services related to messages are provided. The system comprises a central control unit, multiple preinstalled bluetooth transceivers, a bluetooth map, a positioning unit, a display interface unit, a mobile phone interface unit and a message unit, the bluetooth map defines and records bluetooth coordinates in a coverage range of the bluetooth transceivers, the positioning unit can establish the bluetooth coordinates of all bluetooth devices, and the message unit is used for storing various messages including messages uploaded by the user and messages established in the system. The messages uploaded by the user are inputted by the user via an APP (application) on a mobile phone to be uploaded, and the messages established in the system are inputted via a system manager.

Description

technical field [0001] The invention relates to a message transmission and guidance system, in particular to a bluetooth positioning information transmission and guidance system. The application of bluetooth devices is to understand the position and status of objects in a controlled environment, and to know the change of position, and to exchange information through the system of this case, and to provide information-related services. [0002] Background technique [0003] At present, mobile positioning technology can be divided into two types based on satellite and network. The cost of satellite positioning is relatively high, and users need additional equipment support; network positioning requires the deployment of sufficient base stations to provide stable signal quality.

Problems solved by technology

[0003] At present, mobile positioning technology can be divided into two types based on satellite and network. The cost of satellite positioning is relatively high, and users need additional equipment support; network positioning requires the deployment of sufficient base stations to provide stable signal quality. Satellite positioning Technologies such as GPS (Global Positioning System) have the following advantages: use low-frequency signals, all-weather, not susceptible to any weather Global coverage can reach 98%; three-dimensional constant speed and timing with high precision; fast positioning; mobile positioning; the more satellites that can be connected, the more accurate the position is, but its disadvantage lies in its signal Easily blocked by fixed objects such as buildings, walls or trees

[0004] Network positioning technology such as Wi-Fi positioning system is a recently developed technology, and its signal quality will be limited by the density of base stations, environmental factors, and wireless network layout methods. Environmental factors include changes in temperature and humidity, obstacles, and moving objects All will affect the accuracy of positioning. For example, in an environment with high humidity (rainy day), the weakening of the signal is more obvious. The movement of people or vehicles will also affect the stability of the signal distribution.

[0005] In the indoor environment, it is generally impossible to receive GPS signals, and Wi-Fi often has poor signals due to insufficient deployment points, so there are still some shortcomings in using these existing technologies in stores, warehouses or hospitals, because At present, the progress of Bluetooth receiving devices, handheld electronic devices and APP software can be further integrated and applied to become a positioning system
