Specific embodiment
The specific embodiment of the invention is further described with reference to attached drawing：
As shown in Figure 1, a kind of Alcohol mental disorders short message alarm system based on AT89S52 microcontrollers of the present invention, by
Gas sensor, signal conditioning circuit, A/D converter, keyboard, calendar clock circuit, data storage, AT89C52 microcontrollers,
Gsm module, liquid crystal display, voice alarm circuit, control relay circuit, network transmission circuit, mobile phone terminal composition；Its
In, gas sensor is acquired the gas of characteristics of contaminated respiratory droplets, and collected signal is handled by signal conditioning circuit, then
The analog voltage signal changed by signal conditioning circuit output with alcohol concentration, number is converted by A/D converter by analog signal
Word signal is simultaneously transferred to AT89C52 microcontrollers and is analyzed and processed, and is compared with presetting threshold value, when in normal range (NR)
When, only show alcohol concentration；It drinks rank when in abnormal range, liquid crystal display is shown and shows alcohol concentration, sentence
Its fixed property.
The core of system is AT89S52 microcontrollers, is 8 a kind of low-voltage, high-performance CMOS microcontrollers, uses
AT89S52 microcontrollers carry out generating alcohol concentration data after data acquisitions, calculating, processing, and data result implementation is transfinited pair
Than；When alcohol concentration is more than the threshold value of setting, system meeting automatic speech alarming, and it is whole to send data to the mobile phone specified
End, while concentration value this moment is shown by liquid crystal display, it is finally completed the storage to data.
It is mainly made of inside MQ-3 alcohol gas sensors SnO2 gas sensing layers, heater, MQ-3 alcohol gas sensors
Principle change for the resistance value of gas sensing resistance with the variation of alcohol, detection signal is changed into analog voltage by resistance value again
Value, convenient for subsequent conditioning circuit carry out A/D converter conversions, for vehicle operator or other forbid operating personnel after drinking
Detect when participating in the cintest, it can also be used to other need to be to occasion that gas is tested.
For sound circuit using ISD1420 as speech chip, which, which has, uses simple monolithic recording circuit；Record
The sound period is 20 seconds；Switch interface playback can be pulse-triggered or level triggers；High fidelity speech/audio frequency process；Zero energy
Storage, does not need to battery back circuit；Automated power save mode, when a recording or after playback end cycle automatically into falling
