Problems solved by technology

However, the data acquisition function, physical examination function, and upgrade function of automotive diagnostic equipment in the car-machine system are exclusive to the Bluetooth of the automotive diagnostic equipment, and the Bluetooth of the automotive diagnostic equipment can only meet a certain application of one device at a time. connect
If the existing Bluetooth connection mechanism is used, after the vehicle is powered on, if the data acquisition service module is connected to the Bluetooth of the vehicle diagnostic equipment, then when a physical examination or upgrade is required, the physical examination or upgrade application cannot successfully connect to Bluetooth, resulting in failure of the physical examination or upgrade function ;Similarly, if the data acquisition service module is connected to Bluetooth during the physical examination or upgrade process, the connection cannot be successful
Therefore, this Bluetooth connection has a single function, which cannot meet the complex usage conditions of the car-machine Bluetooth system.

Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] The invention provides a Bluetooth switching method.

[0051] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the Bluetooth switching method of the present invention, and the Bluetooth switching method includes:

[0052] In step S100, the data collection service module establishes a connection with the Bluetooth of the vehicle diagnostic equipment.

[0053] In this embodiment, the automotive diagnostic equipment is golo 1s (a Bluetooth diagnostic connector, the model is 1s) as an example for illustration. Of course, other automotive diagnostic equipment can also be used according to actual needs in specific implementation, and can be flexibly selected.

[0054] refer to figure 2 , The car communication system is composed of car machine application system, golo 1s and OB...

Abstract

The invention discloses a bluetooth switching method. The method comprises the steps that a data acquisition service module establishes connection with the bluetooth of automobile diagnosis equipment; an automobile equipment APP is started, then the data acquisition service module disconnects from the bluetooth according to a received upgrading or examination instruction transmitted by the automobile equipment APP if the automobile equipment APP receives the upgrading or examination instruction, and an examination service module establishes connection with the bluetooth according to the received upgrading or examination instruction transmitted by the automobile equipment APP and performs corresponding processing; and the data acquisition service module reestablishes connection with the bluetooth after completion of processing. The invention also discloses a bluetooth switching device. Occupation of the bluetooth resource and waste of the CPU resource can be avoided so that the bluetooth connection requirements of all the functions in the automobile equipment system can be met.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a Bluetooth switching method and device. Background technique [0002] Car machine is the abbreviation of in-vehicle infotainment products installed in the car. Its function is to realize information communication between people and cars, and between cars and the outside world (cars and cars). The mainstream cars on the market use the android operating system, equipped with 3G / 4G communication modules and Bluetooth communication modules. The cars are equipped with functions such as vehicle physical examination (diagnosis), driving track, real-time monitoring, car friends and car groups, and message alarms. APP application system, in order to meet the user's daily driving application needs. [0003] At present, data acquisition is transplanted to the vehicle as a service module, and communicates wirelessly with the OBD (on-board diagnostic, on-board diagnostic system) termina...
