Abstract
The present invention relates to the technical field of automobiles, and discloses a vehicle-mounted wireless charger. A vehicle-mounted complete machine system charges a mobile device by using the vehicle-mounted wireless charger. The vehicle-mounted wireless charger comprises an NFC module and a single-chip microcomputer. The NFC module is connected to the single-chip microcomputer and is configured to quickly pair a Bluetooth module of the vehicle-mounted complete machine system and a Bluetooth module of the mobile device, and information of the mobile device is transmitted to the vehicle-mounted complete machine system through the paired Bluetooth modules. By means of the technical solution, the quick Bluetooth pairing can be realized, and the operation is simple.
Description
Technical field
The present invention relates to automotive field, particularly a kind of onboard wireless charger and the quick matching method of bluetooth.
Background technology
Bluetooth is the radiotechnics of a kind of support equipment short haul connection (in general 10m).Wireless messages exchange can be carried out comprising between numerous equipment such as mobile phone, PDA, wireless headset, notebook computer, related peripherals." bluetooth " technology of utilization, can simplify the communication between mobile communication terminal device effectively, also can communication successfully between simplified apparatus and internet Internet, thus transfer of data becomes efficient more rapidly, is radio communication widening road.Bluetooth adopts distributed network structure and fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint delivery, is operated in the i.e. industry of 2.4GHz ISM(of global general-use, science, medical science) frequency range.Its data rate is 1Mbps.Time division duplex transmission scheme is adopted to realize full duplex transmission.
Between every a pair equipment of Bluetooth technology regulation when carrying out bluetooth communication, must one be leading role's look, another be from role, just can communicate, and during communication, must be searched by main side, and initiation is matched, link setup successfully after, both sides get final product transceiving data.In theory, a bluetooth main side equipment, can carry out communication with 7 bluetooths from end equipment simultaneously.The equipment possessing blue tooth communication function, can switch, be operated in from pattern at ordinary times, wait for other main equipment to connect, when needing, be converted to holotype, make a call to miscellaneous equipment between two roles.When a bluetooth equipment makes a call with holotype, need the Bluetooth address knowing the other side, the information such as pairing password, after having matched, can directly make a call.
Bluetooth main side equipment makes a call, and first searches, and being in around finding out can by the bluetooth equipment searched.Main side equipment finds after end bluetooth equipment, and from hold bluetooth equipment to match, now needs to input the PIN code from end equipment, also has equipment not need input PIN code.After having matched, can record the trust information of main side equipment from end bluetooth equipment, now main side can make a call to from end equipment, and the equipment matched, when calling out next time, no longer needs again to match.
Along with the progress of science and technology, the Bluetooth function of mobile device becomes standard configuration, but defect is pairing work needs, and complicated operation could realize.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of onboard wireless charger and the quick matching method of bluetooth, can realize Bluetooth pairing fast, simple to operate.
