Description
Technical field
The utility model relates to a kind of safety apparatus of the vehicle, specifically relates to a kind of anti-drunk driving device, particularly relates to a kind of anti-drunk driving device that is applicable to automobile.
Background technology
In recent years, along with China's rapid economic development, living standards of the people improve, whole nation motor vehicle number and the surge of chaufeur number, although expressly providing, traffic law forbidden to drive when intoxicated, reach drunk driving after drinking and still exist in a large number but ignore traffic control rules, and cause the delinquent situation of serious consequence still high, cause serious harm for society and broad masses of the people's life, health.
Whether at present, domestic common employing expiration alcohol tester detects navigating mate, drink to determine navigating mate, has the hidden danger of cross infection disease also.Alert of a great variety, powerful, highly sensitive with alcohol tester on the market, but can only be implemented by traffic police personnel pushing-off the wagons, very easily cause traffic tie-up to a certain degree, and this detection mode both wasted police strength, inconvenient again, can not deal with problems from root.
Study from external some in addition, some automakers have developed similar system: at vehicle the pipe of a test usefulness is installed, whether the driver blows facing to pipe, just can detect it and drink.But the people that also will drive can not consciously carry out drunk test after drinking, and on subjective idea, this system has just lost meaning.
Summary of the invention

The utility model is accurate for what detect, and described alcohol detection module comprises alcohol sensor, signal condition amplifying circuit, filter circuit; The alcohol detection module after the signal condition amplifying circuit amplifies, again through filter circuit filtering, is sent into the detection signal that obtains in the micro controller system then and is handled.
Micro controller system described in the utility model is connected with keyboard, GPS positioning navigation module, LCD display, audio call circuit, and GPS positioning navigation module, LCD display are used for driver's driving navigation at ordinary times; When driver's desire generation drunk driving, the GPS positioning navigation module in micro controller system, gives nearest contact person or setting for driving personnel by the audio call circuit notice site message feedback again; Keyboard is used for manual control single chip computer, also can be used for to micro controller system input contact person or sets generation and drive personnel's contact method.
Anti-drunk driving device described in the utility model is characterized in that described alcohol sensor adopts side heating semiconductor-type alcohol gas sensor MQ3, and investigative range is 10 ppm～1000ppm.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it has automatic measurement, intelligent degree height, characteristics such as low in energy consumption, and prevention is driven when intoxicated has good effect, has excellent popularization in actual applications and is worth.
Description of drawings
Fig. 1 is structural principle schematic block diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of anti-drunk driving device, it comprises micro controller system, and micro controller system is connected with power module, alcohol detection module, relay control module, and seatbelt control unit, firing unit control unit are connected with micro controller system by relay control module; Power module provides working power for micro controller system; The alcohol detection module is sent the detection signal that obtains into the control signal of handling the back generation in the micro controller system and is controlled seatbelt control unit, ignition switch control unit respectively by relay control module.
The utility model is accurate for what detect, and described alcohol detection module comprises alcohol sensor, signal condition amplifying circuit, filter circuit; The alcohol detection module after the signal condition amplifying circuit amplifies, again through filter circuit filtering, is sent into the detection signal that obtains in the micro controller system then and is handled.
Micro controller system described in the utility model is connected with keyboard, GPS positioning navigation module, LCD display, audio call circuit, and GPS positioning navigation module, LCD display are used for driver's driving navigation at ordinary times; When driver's desire generation drunk driving, the GPS positioning navigation module in micro controller system, gives nearest contact person or setting for driving personnel by the audio call circuit notice site message feedback again; Keyboard is used for manual control single chip computer, also can be used for to micro controller system input contact person or sets generation and drive personnel's contact method.
Anti-drunk driving device described in the utility model is characterized in that described alcohol sensor adopts side heating semiconductor-type alcohol gas sensor MQ3, and investigative range is 10 ppm～1000ppm.
Micro controller system described in the utility model is the ATmega16 micro controller system.The ATmega16 micro controller system is based on 8 CMOS microcontrollers of low-power consumption of the AVR risc architecture of enhancing.Because its advanced instruction set and single clock cycle instruction execution time, the data throughput of ATmega16 is up to 1 MIPS/MHz, thereby can the contradiction of relieving system between power consumption and processing speed.The In-System Programmable Flash of 16K byte (has the ability that reads while write, be RWW), 512 byte EEPROM, 1K byte SRAM, 32 general purpose I/O mouth lines, 32 general purpose working registers, the JTAG interface that is used for boundary scan, debugging and programming in the supporting pieces, three timer/counters flexibly (T/C) with comparison pattern, the sheet inside/outside interrupts, and serial USART able to programme has the USB of initial conditions detector, 8 tunnel 10 ADC with optional differential input stage programmable-gain (TQFP encapsulation), programmable watchdog timer with sheet internal oscillator, a SPI serial port, and six battery saving modes that can select by software.
