Problems solved by technology

At present, there are still high power consumption and high cost of GPS, especially in local areas where the positioning accuracy is not high enough. For flexible and economical positioning scenarios, especially those requiring high-precision positioning, it cannot solve the demand well.
For example, if the positioned vehicle is temporarily in a closed environment, causing the positioning signal to be blocked, and the personnel cannot communicate with the base station outside the vehicle, there will be a dilemma of being unable to locate the personnel
[0004] In summary, the existing wireless positioning technology needs to be improved urgently to solve the problem that people and vehicles cannot be positioned quickly and accurately when the positioning signal is blocked or cannot communicate with the external base station due to other reasons.

Embodiment 1

[0062] next reference figure 1 . Such as figure 1 As shown, one embodiment of the present invention provides a method for determining the positional relationship between a person and a vehicle.

[0063] Step S101 is a mapping step, the Bluetooth base station maps the information of the first indication area and the second indication area corresponding to the number of the Bluetooth base station from the remote controller.

[0064] Each Bluetooth base station has a unique ID number, and for the unique ID number, a corresponding indication area is set on the storage area of ​​the remote controller, and the information of the indication area is mapped to the Bluetooth base station. Further, the indication area is divided into two sub-areas, namely a first indication area and a second indication area. The first indication area is used to record and indicate the number of successful connections between the Bluetooth terminal and the Bluetooth base station, and the second indicat...

Embodiment 2

[0074] next reference figure 2 . Such as figure 2 As shown, another embodiment of the present invention provides a method for determining the positional relationship between a person and a vehicle.

[0075] Step S201 is a mapping step. The Bluetooth base station maps the information of the first indication area and the second indication area corresponding to the number of the Bluetooth base station from the remote controller.

[0076] Each bluetooth base station has a unique identity number, and for the unique identity number, a corresponding indication area is set on the storage area of ​​the remote controller, that is to say, the indication area corresponding to the number is the same as the number corresponding to the bluetooth base station a map. Further, the indication area is divided into two sub-areas, namely a first indication area and a second indication area. The first indication area is used to record and indicate the number of successful connections between t...

Embodiment 3

[0089] All or part of the steps in the above-mentioned method embodiments of the present invention can be completed by instructing related hardware through a program, so as image 3 As shown, another embodiment of the present invention also provides a device for judging the positional relationship between a person and a vehicle. The device 300 includes a mapping unit 301, a receiving unit 302, a calculating unit 303, a comparing unit 304 and a judging unit 305, wherein,

[0090] A mapping unit 301, configured to map the information of the first indication area and the second indication area corresponding to the Bluetooth base station number from the remote controller;

[0091] The receiving unit 302 receives a personnel signal every time interval T1;

[0092] The calculation unit 303, if the receiving unit receives the personnel signal, increment the value V1 of the first indication area and reset the value V2 of the second indication area, if the Bluetooth base station does ...

Abstract

The invention provides a method, a device and a system for judging the position relationship between a person and a vehicle. The method includes the following steps: a Bluetooth base station maps theinformation of a first indication area and a second indication area corresponding to the number of the Bluetooth base station from a remote controller; a person signal is received once at an intervalof T1; if a person signal is received, the value V1 of the first indication area is progressively increased, and the value V2 of the second indication area is reset; if no person signal is received, the value V2 of the second indication area is progressively increased, and the value V1 of the first indication area is reset; the value V1 of the first indication area and the value V2 of the second indication area are compared with a preset threshold TH; and the position relationship between a person and a vehicle is judged according to the result of comparison. Through the method, the device andthe system for judging the position relationship between a person and a vehicle provided by the invention, a person can be located quickly and accurately, and whether a person is on or off a vehiclecan be determined.

Description

technical field [0001] The present application relates to the technical field of Bluetooth wireless communication positioning, in particular to a method, device and system for judging the positional relationship between a person and a vehicle. Background technique [0002] With the rapid development of wireless communication positioning technology, users propose more and more positioning scenarios, and realize more and more positioning requirements with the help of wireless communication positioning technology. For example, in a positioning system based on vehicles and passengers, through the Global Positioning System (GPS), it can be judged whether the passengers have taken the specified vehicle. If the location of the passenger is consistent or within the set error range, it can be determined that the occupant is on the vehicle or on the vehicle; otherwise, if the location of the occupant is inconsistent with the location of the specified vehicle and is outside the set err...
