Accompanying drawing explanation
Fig. 1 vehicle-mounted alcohol concentration is from reporting to the police from control system
Fig. 2 detecting unit partial circuit schematic diagram
The specific embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
As shown in Figure 1, vehicle-mounted warning certainly comprises three unit from control system: detecting unit 10, processing unit 2 and control unit 30; Wherein detecting unit 10 comprises alcohol gas sensor 12, electric capacity 15, potential device 14 and binistor 13, and main being responsible for detected alcohol concentration and send a signal to processing unit.Processing unit 2 is data transmit-receive control centers, is made up of micro controller system.Control unit 30 comprises three subelements: automobile power source control subelement 31, automobile fog light control subelement 32 and information send controls subelement 33.Automobile power source control subelement 31 is connected and plays automobile power supply switch effect with automobile power source circuit, in the time that alcohol concentration exceeds standard, can make automobile cannot start (this is selectable punction, selects whether to retain according to actual needs this function) by closing automobile circuit; Fog lamp control subelement 32 is connected with automobile fog light, can automatically open fog lamp when automobile starting, to warn pedestrian and vehicle after alcohol concentration exceeds standard; Information sends control subelement 33 and is made up of gsm module, and after detecting that alcohol concentration exceeds standard, processing unit can send note, drunk driving of this vehicle driver of SMS Tip accepter to the phone number prestoring by gsm module.
Detecting unit 10 is responsible for alcohol concentration in inspection vehicle, and generates by himself conversion circuit that to excite next unit be the electric signal of processing unit 2.As shown in Figure 2,24V is automobile power source 11, and QM-NJ9 is alcohol gas sensor 12, if alcohol smell detected, and resistance decreasing between the A-B of alcohol gas sensor 12, the sliding end potential rise of potential device 14.In the time that l.6V this potential rise arrives, ICl high-power switch device 13 is connected, to next unit output high level.
Processing unit 2 starts action after receiving the driving signal of detecting unit 10: the high level that detecting unit 10 is exported, deliver to the P10 mouth of micro controller system, and the real-time trace routine of micro controller system is in the time P10 input high level being detected, micro controller system is started working.Processing unit 2 utilizes micro controller system plug-in to send respectively and excites three substep actuating signals of controlling subelement.In information feedback procedure, processing unit 2 is also responsible for Password Input and is identified, the effect of circuit restoration and reset circuit.Processing unit leaves expansion mouthful, in order in the future further perfect.Processing unit 2 is the retrieval to incoming signal and output control signal by chip microcontroller mainly.And output signal is carried out to power gain, can excite next unit.To coded lock program key feeding cipher, make the operation such as controlled circuit reset of control unit 30 by keyboard, this function can make the password person of setting select to make automobile circuit to restore to drive a car or enter detected state normally to start.
Control unit 30 comprises three subelements: automobile power source control subelement 31, automobile fog light control subelement 32 and information send controls subelement 33.Its P23 mouth output LOW voltage after micro controller system work, the relay high level being connected with automobile power source control subelement 31 obtains electric; P21 mouth output LOW voltage, the relay being connected with automobile fog light control subelement 32 obtains electric; P24 mouth output LOW voltage, the relay being connected with information transmission control subelement 33 obtains electric.Automobile power source control subelement 31, the normally closed contact that coupled relay obtains in electric rear circuit disconnects, and makes motor circuit in off state.Fog lamp control subelement 32, be its relay obtain electric after the closed fog lamp of its open contact of controlling obtain electricly, will light at automobile starting fog tail lamp.Information control subelement 33 is made up of gsm module, is directly connected with the micro controller system of control unit.Gsm module has all basic function that transmission SMS messaging, voice call, GPRS data transmission etc. communicate based on GSM network.Use micro controller system to communicate by letter with gsm module, control gsm module with the AT order of standard and realize the function that sends reminding short message and send to preset phone number in micro controller system reminding short message, if the complaint telephone of supervision department that government is correlated with is as processing unit preset number, just can know in real time like this which automobile storage is in drunk driving behavior.Control unit 30, except comprising above-mentioned three large subelements, also comprises sound circuit and liquid crystal display circuit.Sound circuit is made up of buzzer phone, and it is directly connected with micro controller system, in the time occurring that in car, alcohol concentration exceeds standard situation, just can send warning sound.Liquid crystal display circuit is to use Liquid Crystal Display to be directly connected with micro controller system, and in car, alcohol concentration exceeds standard in situation to driver's warning.
Described binistor 13 is switching element T WH8778.
Described micro controller system is AT89S52, as the control center of system, receives signal and sends command adapted thereto.
Described gsm module is the GTM900C of Huawei, as information transmitting terminal mouth.
