Embodiment
Below in conjunction with accompanying drawing and preferred scheme, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, for the structured flowchart of the counter of a kind of bluetooth equipment among a small circle of the present invention, this counter is with control chip 1 for core, is powered by power supply 8, and control chip 1 is electrically connected with filtering circuit 2, reset circuit 3, clock circuit 4, driving circuit 5.Described filtering circuit 2 is connected with PCB antenna 6 with communication; Described driving circuit 7 is also connected with LCD MODULE 7, and LCD MODULE 7 is also powered by power supply 8.Described control chip 1 has the function of reception, transmission, process, storage data, actual carry out Bluetooth terminal number quantitative statistics among a small circle time, this control chip 1 is equivalent to the three zones block comprising statistical system, i.e. bluetooth module, storer and microprocessor.
Embodiment one: is as shown in Figure 2 a kind of control flow chart realizing adding up Bluetooth terminal quantity in the control chip 1 statistical method of the present invention being write counter of the present invention in the mode of program.Control chip 1 in the present embodiment adopts the chip CC2540 of preferred TI company, this chip compatible bluetooth 4.0BLE agreement, and contains processor and storer, therefore directly uses this chip to complete function of the present invention in the present embodiment.
First initialization is carried out to the program of CC2540 control chip 1, and set one " query display cycle " as 3 seconds, this cycle is made up of many " inquiry control cycle ", namely within " query display cycle ", complete the once statistics of all Bluetooth terminals within the scope of Bluetooth signal, this cycle can set as the case may be.In one " inquiry control cycle ", namely complete one query control procedure, this control chip 1 has the tally function of counter by programmed control, and after initialize routine, the initial value of counter is set to 0, then, control chip 1 sends the Bluetooth terminal being in " inquiry scan state " within the scope of GIAC or DIAC request signal, the Bluetooth terminal response inquiry of inquiry scan state, send FHS packet to control chip 1, control chip 1 extracts the Bluetooth terminal address information in packet, and store, unison counter adds 1, then control chip continues to send GIAC or DIAC inquiry Bluetooth terminal, next terminal response inquiry, send FHS packet to control chip 1, control chip 1 receives packet and extracts address date, the address of rear extraction and the address date stored are contrasted simultaneously, see and whether repeat, if repeated, give up, Counter Value is constant, control chip continues inquiry, if do not repeat, then storage address information, unison counter value adds 1, then continue to repeat inquiry, until " query display cycle " terminates, now display counter value in LCD MODULE 7.By this kind of mode, count the quantity being in the Bluetooth terminal of inquiry scan state within the scope of Bluetooth signal.
Embodiment two, mobile phone, notebook computer etc. are comprised the smart machine of Bluetooth function directly as the carrier of application statistical method of the present invention, directly use as counter by mobile phone, notebook computer etc., can in the system of these Bluetooth terminals direct Application and Development software, window display statistical figure established by software, complete Bluetooth terminal statistical function, claim the Bluetooth terminal (as mobile phone, notebook computer etc. comprise the smart machine of Bluetooth function) installing this application software to be main equipment in the present embodiment once, its software control flow process as shown in Figure 3.
First set one " query display cycle " as 2 seconds, open the application software on main equipment, in one " inquiry control cycle ", namely one query control procedure is completed, program initialization, counter O reset, then, start the Bluetooth function of main equipment, send GIAC or DIAC inquiry Bluetooth terminal around, the Bluetooth terminal of inquiry scan state is in scope, the Bluetooth terminal response inquiry of inquiry scan state, send FHS packet to main equipment, main equipment extracts the Bluetooth terminal address information in packet, and store, unison counter adds 1; Then main equipment continues to send GIAC or DIAC inquiry Bluetooth terminal, next terminal response inquiry, send FHS packet to main equipment, main equipment receives packet and extracts address date, then contrast with the address date stored, see and whether repeat, if repeated, give up, Counter Value is constant, and main equipment continues inquiry, if do not repeat, then storage address information, unison counter value adds 1, then continues to repeat inquiry, until a query display end cycle, now display counter value on primary device application window.Next " query display cycle " repeats this query script.By this kind of mode, the Bluetooth terminal being in inquiry scan state within the scope of Bluetooth signal can be counted.
The invention discloses a kind of counter and method thereof of Bluetooth terminal among a small circle, during concrete enforcement, can by this Application of Statistic Methods in described counter, or the method being arranged on the form of application software has on the smart machine of Bluetooth function, can realize necessarily among a small circle in the quantitative statistics of all Bluetooth terminal numbers, this statistical method is accurate, quick, can be applicable to all size occasion of Bluetooth terminal, unrestricted.
