Problems solved by technology

[0004] In the field of indoor positioning, a common positioning method is to build a positioning system first, and then carry a positioning device on the moving target, and continuously transmit signals between the positioning device and the positioning system to realize the positioning of the moving target. This positioning method is commonly used In the monitoring and management of personnel in the fields of fire protection and security, the management level of fire protection and security has been improved, but it also has shortcomings. For example, when a fire occurs in a building, some equipment in the positioning system will be blocked. At this time, the positioning system will not be able to know the specific location of the firefighters or security guards. When the firefighters or security guards are trapped in the sea of ​​fire or fainted, the control center will not be able to know their specific locations, thus Failure to rescue them in time poses a huge threat to the life safety of firefighters or security personnel

Embodiment 1

[0031] Embodiment one: see figure 1 , figure 2 , in the figure, the positioning method based on the movable positioning beacon is as follows: the positioning sensor U1 and the wireless data transmitter U2 are carried on the target to be positioned, and a positioning system is set up around the target to be positioned. The positioning system contains three positions that are not fixed The movable positioning beacon of the positioning target is located within the positioning range of the positioning system. When positioning,

[0032] 3 mobile positioning beacons regularly broadcast messages to the outside world;

[0033] The positioning sensor U1 receives and processes the messages broadcast by the three movable positioning beacons, obtains the MAC address in each message and the RSSI value of the broadcast message and sends them to the wireless data transmitter U2, and the wireless data transmitter U2 then Send the MAC address and RSSI value wirelessly, and the positioning s...

Embodiment 2

[0043] Embodiment two: see figure 1 , image 3 , the numbers in the figure are the same as those in Embodiment 1, the representative meanings are the same, and the working process is basically the same, and the similarities will not be repeated. The difference is: the serial communication port (P0.2, P0 .3) Connect with the serial communication port (TXD, RXD) of the wireless data transmitter U2, and the positioning sensor U1 transmits the MAC address and broadcast information in each message through its serial communication port (P0.2, P0.3) The RSSI value of the message is sent to the wireless data transmitter U2.

[0044] The movable positioning beacon is a Bluetooth positioning beacon (iBeacon), which broadcasts a Bluetooth signal, the positioning system is a Bluetooth positioning system, and the positioning sensor U1 is a Bluetooth positioning sensor.

[0045] The Bluetooth positioning beacon contains a Bluetooth positioning beacon and a first battery. The power supply ...

Abstract

The invention relates to a positioning method based on a movable positioning beacon. The method comprises steps that a to-be-positioned target is allowed to carry a positioning sensor and a wireless data transmitter, and setting a positioning system around the to-be-positioned target, wherein the positioning system comprises N movable positioning beacons in fixed positions, and the N movable positioning beacons regularly broadcast reports outwards during positioning; the positioning sensor receives the reports broadcast by the N movable positioning beacons and carries out processing so as to obtain and send out MAC addresses in the reports and RSSI values of the broadcast reports to the wireless data transmitter for transmitting out in a wireless manner; and the positioning system receives the MAC addresses and the RSSI values sent by the wireless data transmitter, and acquires distance information between the to-be-positioned target and each movable positioning beacon according to the MAC addresses and the RSSI values. According to the invention, a positioning problem when the positioning system is damaged in case of accidents like a fire disaster is solved and the positioning method is precise in positioning and convenient to operate.

Description

[0001] (1) Technical field: [0002] The invention relates to a positioning method, in particular to a positioning method based on a movable positioning beacon. [0003] (two), background technology: [0004] In the field of indoor positioning, a common positioning method is to build a positioning system first, and then carry a positioning device on the moving target, and continuously transmit signals between the positioning device and the positioning system to realize the positioning of the moving target. This positioning method is commonly used In the monitoring and management of personnel in the fields of fire protection and security, the management level of fire protection and security has been improved, but it also has shortcomings. For example, when a fire occurs in a building, some equipment in the positioning system will be blocked.
