Of the present utility model is be prevention drunk driving and the vehicle-mounted detecting device that designs based on Bluetooth of mobile phone vehicle-mounted alcohol detecting device.This detecting device detects the alcohol concentration in driver's oral environment, by single-chip microcomputer, analyzing and processing is carried out to data, and make comparisons according to result and reference value, in time by information feed back to driver, reaching with this facilitates human pilot self-drunk driving before travel to detect, check the unsafe problems such as drunk driving in time, reduce drunk driving traffic hazard incidence, effect is better.In addition, system architecture of the present utility model is simple, with low cost, practical and convenient, has higher practicality and feasibility.
Accompanying drawing explanation
Fig. 1 is detector arrangement block diagram of the present utility model;
Fig. 2 is the system hardware way circuit of the utility model embodiment.
Embodiment
The input of the output termination analog/digital conversion circuit 2 of the utility model alcohol sensor 1, the output of analog/digital conversion circuit 2 connects the input of single-chip microcomputer 3, and the output of single-chip microcomputer 3 connects the input of bluetooth module 4, and bluetooth module 4 connects cell-phone customer terminal 5 by bluetooth; In addition, single-chip microcomputer 3 also connects storer 6, and storer 6 is connected with latch chip 7; Single-chip microcomputer 3 is connected with analog/digital conversion circuit 2 through frequency-halving circuit 8; In addition, single-chip microcomputer 2 is connected with power circuit 10 with reset circuit 9 respectively.The chip that this system mainly utilizes has: singlechip chip 80C51, memory chip 2764, analog/digital conversion chip ADC0809, bluetooth module HC-05, alcohol sensor chip ZYMQ-3, latch chip 74LS373, d type flip flop.
Concrete connection is: No. 6 pins of the alcohol sensor 1 i.e. ZYMQ-3 of Fig. 2 are connected with No. 4 pins and obtain output terminal, export the IN0 end in first analog input end of termination analog/digital conversion chip ADC0809 and Fig. 2, data output end D0 ~ the D7 of ADC0809 connects the data input pin P0 mouth of single-chip microcomputer 80C51, the TXD of the HC-05 of the serial ports RXD of single-chip microcomputer 80C51 and bluetooth module and Fig. 2 is connected, and the RXD of serial ports TXD and the HC-05 of 80C51 is connected.In addition, the P0 mouth of single-chip microcomputer 80C51 also meets the D0 ~ D7 latching chip 74LS373, and the Q0 ~ Q7 latching chip 74LS373 meets the A0 ~ A7 of storage chip 2764; The ALE terminal of single-chip microcomputer 80C51 connects the CK terminal of frequency-halving circuit d type flip flop, and the Q connecting terminals of d type flip flop is received on the CLK terminal of ADC0809; P2.0 ~ the P2.4 of single-chip microcomputer 80C51 meets the A8 ~ A12 of storage chip 2764.
Alcohol concentration reference value 1 and reference value 2 is detected in advance by programming two national regulation drunk drivings, and by it stored in memory chip 2764.Alcohol sensor chip ZYMQ-3 detects human oral cavity alcoholic strength, and the output due to chip is simulation current flow, is therefore connected with port 4 by port 6, and by 1K resistance eutral grounding, makes the magnitude of current change into voltage.This voltage sends into the IN0 input end of analog/digital conversion chip ADC0809, sends into single-chip microcomputer 80C51, treat single-chip microcomputer process after converting thereof into corresponding digital quantity by P0 mouth.The result handled well and two reference values pre-set compare by single-chip microcomputer 80C51, when result is lower than (as alcohol concentration≤20mg/100ml) during reference value 1, single-chip microcomputer sends signal 1 to cell-phone customer terminal by bluetooth module, and mobile phone terminal display is normal; When result is higher than reference value 1 but lower than (as 20mg/100ml< alcohol concentration <80mg/100ml) during reference value 2, single-chip microcomputer sends signal 2 to cell-phone customer terminal by bluetooth module, mobile phone terminal display driver from drunk driving; When alcohol concentration is higher than (as alcohol concentration >=80mg/100ml) during reference value 2, mobile phone terminal display drunk driving.
