4, liquid crystal display shows " please after a while ": carry out liquid crystal display show " " order please after a while, this is in order to point out the user, system starts, sensor is adding electric preheating.
5,1.2V powers up, and delays time 10 seconds: when carrying out this step, micro controller system is delayed time 10 seconds (in this delay time, LCDs shows " please after a while ", and alcohol sensor adds 1.2V simultaneously).1.2V the implementation method that powers up: 26 pin of micro controller system U1 are high level, and 1 pin of control DCDC step-down chip U4 makes its work, and like this, the power supply of 1.2V will be powered to alcohol sensor by 1 pin of alcohol sensor S1.
6, switch display interface and be test alcohol concentration interface, micro controller system refreshes the displaying contents of read-out by the control to LCD MODULE, and the demonstration of liquid crystal display becomes tests the interface of awaiting orders, and shows " 0.00mg/L ".
More than for interrupting the execution content of initialization function, after this section program is complete, liquid crystal display is ready, show that alcohol concentration is " 0.00mg/L ", this moment, the personnel that drive were with the microgenerator of flabellum to blow in induction opening, make flabellum drive microgenerator M1 twirl, carry out basic observing and controlling operation, carry out measurement and control program this moment.To wait until after measurement and control program finishes from " button is pressed " downward flow process among Fig. 6 and just carry out, its description is seen for details hereinafter.
Four, measurement and control program
Measurement and control program as shown in Figure 7, obtain the magnitude of voltage of lithium ion battery from AD, judge whether battery electric quantity is low, switch multichannel and select the passage of module, obtain the magnitude of voltage of microgenerator from AD, initialization warning function, judge whether electrical generator rotates, switch the passage that multichannel is selected module, obtain the magnitude of voltage of alcohol sensor from AD, this magnitude of voltage is converted into the alcohol concentration value, show this value by LCDs, judge whether concentration exceeds standard, program is loose and is transferred two parts to: 1, during concentration over-standard, driving instruction 2 is forbidden in execution, when concentration does not exceed standard, carry out the driving instruction.Measurement and control program is finished.Concrete implementation status is as follows:
1, obtain magnitude of voltage (lithium ion battery) from AD: owing to switched the passage of multichannel selection module U3 the interruption initialization is the passage of lithium ion battery, the positive pole of battery is added to 8 pin of multiple way switch U3 by aerotron Q1, after the output of 9 pin, be added to 6 pin of AD conversion U2 by resistance R 103, the digital quantity of the representative battery real-time voltage after the conversion is sent to micro controller system U1, demonstrate electric weight through being sent to Liquid Crystal Module U6 after the U1 processing, when if cell pressure drops to 3.5V, electric weight icon on the liquid crystal display begins flicker and makes electric weight icon inside become white, informs that the personnel of driving in time charge.During charging, the charging connection lead is inserted into respectively on interior 12V Cigarette lighter of car and the J701, the charging beginning, when micro controller system detects cell pressure and reaches 4.2V, can make in the battery electric quantity icon on the liquid crystal display to become black, inform that charging is full, 8 pin of U1 become 8 pin that low level is added to U9 from high level simultaneously, force the U9 charging to finish, inform that the personnel's charging of driving is full, please pull out the charging connection lead.
Wherein, R201 and R202 form the loop provides reference voltage for the AD module; R203 and C201 form the loop, for the AD module provides external clock.
2, the multichannel handover module switches, and promptly to the closing of lithium ion battery TCH test channel, to alcohol sensor S1 with to the unlatching of microgenerator M1: purpose makes microgenerator enter armed state.Concrete implementation is, program makes 5 pin (control of the corresponding lithium ion battery TCH test channel) output low level of micro controller system U1,19 pin (control of corresponding alcohol sensor) output low level, 20 pin (control of corresponding microgenerator) output high level, to be connected to 5 pin of micro controller system U1 be low level to 8 pin of multichannel handover module U3 (lithium ion battery control) like this, 19 pin that 13 pin of U3 (alcohol sensor control) are connected to micro controller system U1 are low level, and 20 pin that 5 pin of U3 (microgenerator control) are connected to micro controller system U1 are high level.The input of microgenerator at this moment is connected to 4 pin of multichannel handover module U3, and this signal can be by the complete output of 3 pin of U3.
3, obtain magnitude of voltage (microgenerator) from AD: more than, multiplexing module is switched to the passage of microgenerator, therefore when the user when gas hole is blown, microgenerator M1 rotates, produce voltage, 4 pin input by multiplexing module U3, the output of 3 pin, and process resistance R 103 enters 6 pin of AD conversion chip U2, the AD chip changes into digital signal with this analog signal, exports 40 of micro controller system U1 to from 11 pin to 18 pin of AD chip, 41,42,43,44,1,2,3 pin are after micro controller system U1 obtains this signal, learn that microgenerator rotates, will carry out follow-up initialization warning function order.
4, initialization warning function.The effect of this section order is that 10 pin and 22 pin of control single chip computer U1 are high level, and the transmitter module with regard to control loop can externally not send driving or forbid the driving instruction like this.About the instruction of how controlling driving or forbidding driving a vehicle, will explain in the concrete process of carrying out below.
5, switch multichannel and select module U3, purpose is to switch the alcohol sensor signal to test macro.Concrete implementation is: program makes 5 pin (control of the corresponding lithium ion battery TCH test channel) output low level of micro controller system U1,20 pin (microgenerator control) level is low, the level of 19 pin (alcohol sensor control) is high, 5 pin that 8 pin of multichannel handover module U3 (lithium ion battery control) are connected to micro controller system U1 are low level, the level of 13 pin (alcohol sensor control) is high, 5 pin (microgenerator control) level is low, and the output of alcohol concentration sensor is ready.Because test begins (microgenerator rotation), so 2 pin of alcohol concentration sensor have the output of a voltage, this voltage can be along with the variation of survey alcohol concentration linear change.The output voltage of 2 pin enters 1 pin of multidiameter option switch U3, because multidiameter option switch U3 is by Single-chip Controlling, switch to the alcohol sensor state, so, this magnitude of voltage can be exported from 2 pin, arrive 6 pin of AD module U2 through resistance R 103, AD module U2 changes into digital quantity to this analog quantity, export 40,41,42,43,44,1,2,3 pin of micro controller system U1 to from 11 pin to 18 pin, after micro controller system U1 obtains this signal, carry out corresponding algorithm process and obtain concentration value, this concentration value shows by the liquid crystal display module.
6, judge whether concentration value exceeds standard, the concentration value that obtains, the concentration of driving when intoxicated with national regulation in micro controller system compares, and judges whether concentration exceeds standard, and then carries out the diffusing commentaries on classics of program.
7, program is loose and is transferred two parts to: concentration over-standard, and carry out and forbid the driving instruction; Concentration does not exceed standard, and carries out the driving instruction.If the concentration of being surveyed is higher than national safety standard, system will be from the 22 pin output low levels of micro controller system U1, through the base stage of resistance R 803 to aerotron Q5, control this aerotron conducting, the collecting electrode of aerotron Q5 has a 5V power supply like this, this power supply is given chip power supply by 18 pin that isolation diode is added to coding chip, pass through 10 pin of resistance R 607 simultaneously to coded portion U8, behind the coding by this chip, go out by 17 human hair combing wastes, through 2 pin of resistance R 608,, launch by emitting antenna 4 by the modulation of this module to radiating portion BX1.This is one and forbids train signal.If the concentration of being surveyed is lower than national safety standard, system will be from the 10 pin output low levels of micro controller system U1, through the base stage of resistance R 801 to aerotron Q4, control this aerotron conducting, the collecting electrode of aerotron Q4 has a 5V power supply like this, this power supply is given chip power supply by 18 pin that isolation diode is added to coding chip, pass through 11 pin of resistance R 606 simultaneously to coded portion U8, behind the coding by this chip, go out by 17 human hair combing wastes, through 2 pin of resistance R 608,, launch by emitting antenna 4 by the modulation of this module to radiating portion BX1.This is a train signal.
So far, finished the testing process of a standard, circulation is carried out and is entered the epilogue that interruption is finished after 2 minutes, if the signal that has button to press during this then directly enters the epilogue that interruption is finished.Epilogue after interruption is finished, just shown in Fig. 6, shutdown system power supply and close multichannel and select all passages of module.Specifically the implementation status in circuit is as follows:
1, shutdown system power supply: because the control of power supply T5V finished by aerotron Q2, so program uprises 18 pin level of micro controller system, and the base stage of the signal control Q2 of 18 pin makes the Q2 emitter to collector cut-off, and the voltage of 5V is to the path disconnection of system.Finish the task of power-off.
2, close multichannel and select all passages of module.Be set to high level by 19 pin, 20 pin micro controller system U1, the control multichannel is selected 13 pin and 5 pin of module U3, reaches the purpose of cutting off microgenerator and alcohol sensor signal line.
So far, interrupt routine is finished, and returns principal function, the program of actuating system sleep, and total system enters low-power sleep state.
The working process and the principle of wireless receiving control part are summarized as follows:
As can be seen shown in Figure 8 by wireless receiving control part diagram of circuit, the content of carrying out wireless receiving control mainly is divided into following components:
The signal judgment of drinking, the judgement of train signal, the judgement of key twisting, and the judgement of ON line high level time.Having done at these judging points of task is the key of native system.
One, receives and forbid the instruction of driving a vehicle
When receiving this moment chaufeur represented after modulated by receiving wire, the wireless receiving demodulator circuit U1 of wireless receiving part drunk wine, when concentration surpasses the information of national safety standard, after the U1 demodulation, export the 14th pin that is added to decoding circuit U2 from the 2nd pin, after the U2 inner decoding, export a high level (U2 is the unlatching demoder of usefulness) from the 11st pin.This signal exports 8 pin of micro controller system U3 to through resistance R 2, after micro controller system receives this signal, driven by program 19 pin are the square-wave signal of 1S for the output cycle, drive buzzer phone BELL by Q1 so interrupted chimes of doom takes place, and tell navigating mate can not start vehicle this moment.Micro controller system 18 pin output this moment be low level, the aerotron Q2 attitude of remaining stationary is ended, the electric current that flows through R10 is far smaller than the working current that relay is opened, and can't start vehicle so start by force also in interrupted time of fire alarming.
Two, receive the driving instruction
If this moment, navigating mate was not drunk, wireless receiving demodulator circuit U1 is subjected to the information of representing navigating mate not drink can normally to start vehicle after modulated by receiving wire and is added to the 14th pin of demoder from the output of the 2nd pin after by the U1 demodulation, after the inner decoding of U2, export a high level from the 10th pin, this signal is by 9 pin of resistance R 3 to micro controller system U3, after micro controller system receives this signal, high level of driven by program 18 pin output (was delayed time 2 minutes, purpose is to allow the personnel of driving have sufficient time to start vehicle), be added to the base stage of aerotron Q2, thereby make the Q2 conducting, this moment, relay K was ready (if promptly twist car key, relay will adhesive, guarantee that vehicle can normally start), open the automobile starting key switch, start-up circuit gets electric work in the car.
Three, the parking behind the startup automobile is judged
Illustrate: the ON line is the green line in the schematic diagram, and promptly car engine motivation ignition wire has the 12V level during driving, does not have any level during parking.
After starting automobile, judge whether the high level on the ON line was kept 2 minutes, if this high level was kept 2 minutes, illustrate that automobile normally starts, if within these 2 minutes, the ON line has become low level, and program will drag down 18 pin of micro controller system U3, the armed state of the relay of removing controls so; If the ON line is in high level in 2 minutes always, program will wait for that the ON line becomes low level (being automobile flameout) so, when the ON line is low level by the time, program is carried out one section time-delay of 30 minutes, and (this moment, relay still was ready, satisfy to stop 30 minutes not needs detect motorist's expiration alcohol concentration again), if ON line has become high level during this, program is carried out timing 30 minutes (this is in order to satisfy restarting of parking period less than 30 minutes, not need to detect again motorist's expiration alcohol concentration) again.If, parking period surpasses 30 minutes, and (the ON line became low level after 30 minutes, still do not become high level), relay will be cancelled armed state (by 18 pin of programming control micro controller system U3 so, it is become low level), the judgement command program that stops about the back of driving a vehicle is finished like this, and returns the program segment that initial decision is prohibited car instruction and driving instruction.
Twisting car key when four, not detecting
If just start vehicle without detecting, receiving demodulation circuit U1 does not receive any information; The 2nd pin does not just have the information output after the demodulation, and the 10th, 11 of demoder U2 output pin does not have high level output yet.Micro controller system does not receive the signal that sends from demoder U2, so can not carry out the judgement of drinking and not drinking, this moment, the 12V power supply was added to resistance R 10 and 5V voltage of the last generation of 5V stabilivolt DW by the coil of relay K, be added to 16 pin of U3 by resistance R 6, after micro controller system U3 receives this signal, make the 19 pin output low levels of U3, making the Q1 conducting power up for buzzer phone BELL yowled buzzer phone 10 seconds, inform navigating mate, even without drinking, do not start power actuated vehicle without detecting yet.
The invention has the beneficial effects as follows: start vehicle after can drinking to human pilot and carry out by force System detects, and vehicle can't be started travel, and prevents the accident-proneness of driving when intoxicated Generation, ensure that broad masses of the people's personal safety and property is without prejudice.
