Problems solved by technology

[0008] However, during the communication connection mode of two Bluetooth devices, due to the protocol specifications of Bluetooth 3.0 and below, a Bluetooth slave (set in the Bluetooth tire pressure sensor) can only be connected by a Bluetooth master (set in the Bluetooth master device) Control, can not be controlled by other bluetooth hosts, so the online communication between bluetooth devices is completely controlled by a bluetooth host (bluetooth master control device) to a bluetooth slave (bluetooth tire pressure sensor)
In other words, in a vehicle with four tires, if each tire is equipped with a Bluetooth tire pressure sensor, even if the Bluetooth master device has pre-paired these Bluetooth tire pressure sensors successfully, in actual use, The Bluetooth main control device can only receive the tire pressure signal sent by one of the Bluetooth tire pressure sensors whose connection request has been confirmed. As for the tire pressure signals sent by the Bluetooth tire pressure sensors of the other three tires, the Bluetooth main control device cannot take over
This mode brings great restrictions and inconvenience to the use of Bluetooth-based TPMS
[0009] In the above-mentioned prior art, the tire pressure monitoring system realized through Bluetooth mainly only transmits tire pressure monitoring signals through Bluetooth, and can only do one-to-one signal transmission. In other words, only one tire can be detected. pressure signal, the function and effect are limited, and it is urgent to break through and improve

Embodiment 1

[0075] The present invention first proposes a smart bluetooth vehicle tire positioning and pairing system for use in a vehicle with multiple tires 200, such as figure 1 As shown, a predetermined number N of tire condition monitoring modules 210 and one smart mobile terminal 300 are included. In this embodiment, N is four, that is, a four-wheeled vehicle, but it is not limited to four during actual use.

[0076] Each tire condition monitoring module 210 is arranged at each tire 200, including a first Bluetooth device 218 based on Bluetooth 4.0 or above, a proprietary MAC address 290, and a proprietary group name 260, in each tire condition monitoring module 210 , each MAC address 290 is different. At the same time, the tire condition monitoring module 210 also includes a power sensor 213 for detecting the movement information 213S of the tire 200; a tire pressure sensor 211 for detecting the tire pressure information 211S of the tire 200; and a first The power supply device 2...

Embodiment 2

[0094] Preferably, the present invention proposes a second preferred embodiment, such as image 3 Shown is a smart bluetooth tire positioning and pairing system used in a vehicle with multiple tires 200, including a predetermined number N of multiple tire condition monitoring modules 210, an intelligent mobile terminal 300 and a bluetooth central control Taiwan 100.

[0095] Each tire condition monitoring module 210 is set at each tire 200, and includes a first Bluetooth device 218 based on Bluetooth 4.0 or above, a proprietary MAC address 290, and a proprietary group name 260, among multiple tire condition monitoring modules 210 , each MAC address 290 is different.

[0096] The smart mobile terminal 300 includes a second Bluetooth device 318 based on Bluetooth 4.0 or above and a tire positioning program 270. The tire positioning program 270 pre-stores positioning pairing information 333, and the positioning pairing information 333 includes a predetermined number N of multipl...

Abstract

The invention relates to the technical field of radio direction finding and specifically relates to a smart Bluetooth tyre positioning pairing method and positioning pairing system for carrying out positioning based on a Bluetooth 4.0 technology. The system comprises a plurality of tyre condition monitoring modules and a smart mobile terminal. The tyre condition monitoring modules are equipped with Bluetooth slaves. The smart mobile terminal is equipped with a Bluetooth host. According to the method and the system, Bluetooth positioning of the tyre condition monitoring modules and the smart mobile terminal is not carried out in a licensed connection mode of the Bluetooth and is carried out under the unlicensed connection condition. The tyre condition monitoring modules are equipped with population names of the same population and different MAC address and position names. The slaves transmit signals externally in a broadcast mode and the host receives the signals in a scanning mode. When the smart mobile terminal gets close to the tyre condition monitoring modules, the radio frequency signal strength of the tyre condition monitoring modules is analyzed, if the strength is increased, the positioning pairing is successful. According to the method and the system, the complicated Bluetooth license operation is avoided and the use is relatively convenient.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of radio orientation, in particular to a positioning technology based on bluetooth. [0003] 【Background technique】 [0004] With the improvement of living standards, vehicles have become people's main means of travel. Traffic accidents caused by tire blowouts have attracted people's attention. The tire pressure monitoring system based on Bluetooth signals is small in size, power saving, long transmission distance, and anti-interference performance. Well, it is becoming more and more popular. [0005] Prior art CN104442232A discloses a tire pressure monitoring display receiver and its display method, the tire pressure monitoring display receiver includes a processor, a Bluetooth transmission module connected to the processor and / or a serial data interface, the processor It includes at least a numerical conversion module for converting the electrical signal into a specific tire pressure value; a buff...
