Abstract
The invention discloses an intelligent remote controller based on Bluetooth. The remote controller body comprises a Bluetooth low-power-consumption single-chip, a gyroscope, an accelerometer, a temperature sensor, a microphone, a button and a battery, and is used for realizing intelligent control operations of an aerial mouse, body feel and voice; the invention provides a quick pairing method of the remote controller and a host computer. The quick pairing method comprises the following steps that the remote controller sends a Bluetooth ADV_NON_CONN_IND packet form non-directional broadcast packet; after the host computer receives the Bluetooth ADV_NON_CONN_IND packet form non-directional broadcast packet, the host computer analyzes VENDOR information and judges that whether the remote controller supported by the host computer requests pairing; whether the distance between the remote controller and the host computer is in a permitted pairing range or not is performed through RSSI ( Received Signal Strength Indication) value; the host computer invokes Bluetooth standard pairing service to pair with the remote controller. The intelligent remote controller has the beneficial effect that pairing can be carried out only by operating a remote controller end, and complicated operation in a host computer end is not needed.

The step of described telepilot and the quick matching method of main frame is:
(1) telepilot sends non-directive property broadcast packet, and the packet format packing of the data based bluetooth ADV_NON_CONN_IND of broadcast packet includes telepilot manufacturer and model (VENDOR) information and request unpaired message etc.
(2) at a finger daemon of smart host bottom layer operation, or at an APK of application layer operation, be used for monitoring blue-teeth data, main frame is after receiving the broadcast packet of telepilot transmission, first finger daemon or APK can analyze this packet, parse VENDOR information, if belong to the telepilot of main frame support, indicate that telepilot is in request pairing; Again further by judging the RSSI value of this broadcast packet, with judge telepilot from the distance of main frame whether in allowing the scope of pairing.
(3) if judge that by RSSI telepilot is in certain scope, finger daemon or APK can call the bluetooth standard pairing service of bluetooth host, start the HOST SCAN function of bluetooth host, scanning telepilot, start pairing service, match with this telepilot.
The performing step that described telepilot is realized speech voice input function is:
(1) microphone is input to bluetooth low-power consumption single-chip by the voice messaging of collection, and bluetooth low-power consumption single-chip carries out compression coding to voice signal, is packaged into HID packet and sends to main frame by bluetooth;
(2) can receive with the bluetooth host of telepilot pairing the HID packet that telepilot sends, utilize and be arranged on the virtual audio driver decoded data packets on main frame, reduction voice signal.
The invention has the beneficial effects as follows: without increasing any additional modules, only need remote controller end, do not need host side to operate can to realize quick pairing.
Accompanying drawing explanation
Fig. 1 is the hardware block diagram of intelligent remote controller of the present invention;
Fig. 2 is the process flow diagram of the quick matching method of the present invention;
Fig. 3 is the realization flow figure that telepilot of the present invention is realized speech voice input function;
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
With reference to Fig. 1, intelligent remote controller based on bluetooth, comprise remote controller body, described remote controller body comprises bluetooth low-power consumption (BLE) single-chip 11, gyroscope 12, accelerometer 13, temperature sensor 14, microphone 15, button 16 and battery 17, described gyroscope 12, accelerometer 13, microphone 15 and temperature sensor 14 are connected with data input pin and the corresponding control end of described bluetooth low-power consumption single-chip 11 respectively; Described bluetooth low-power consumption single-chip 11 and smart host devices communicating, the information such as code request, control signal are passed to smart host.
The system level chip of the described bluetooth low-power consumption single-chip 11 BLE physical layer block that has been integrated and MCU, and support the functions such as tandom number generator, analog comparator, CRC check.
When telepilot user rotates telepilot, the angular velocity information that described gyroscope 12 can rotate output according to telepilot, in conjunction with the time of rotating, is exported the aerial trace information of corresponding mouse to smart host end, forms the air mouse of smart host is controlled;
