Embodiment Construction

[0018] One, hardware equipment

[0019] The system block diagram is shown in Figure 1. The whole system consists of a single-chip microcomputer, several air sensors, signal conditioning circuits, display screens, control buttons, buzzers and window control interface circuits.

[0020] System circuit design:

[0021] This system adopts SN8P1909 series industrial-grade single-chip microcomputer of SONIX Company as the control core. The microcontroller is an 8-bit microcontroller, including a large-capacity (8K-word) program memory (OTP ROM), 512-byte data memory; an 8-bit basic timer T0, with RTC (real-time clock) function , Two timer / counters (TC0, TC1), one watchdog timer, six interrupt sources (T0, TC0, TC1, SIO, INT0, INT1), 5-channel 16-bit ADC, programmable gain amplifier (PGIA) , Boost regulator (Charge pump / Regulator), 2-channel PWM output (PWM0, PWM1), 2-channel buzzer output (BZ0, BZ1), 4-common and 32-segment LCDdriver. Because the single-chip microcomputer integrates a v...

Abstract

The invention relates to the automobile electronic technology field, in particular to an automobile environment monitoring system on the basis of an air sense technology and an electronic control technology. The invention consists of a singlechip, an air sensor, a signal conditioning circuit, a display screen, a control button, a buzzer and a vehicle window control interface circuit, wherein, the air sensor performs real-time monitoring on contents of gases like oxygen, carbon monoxide, formaldehyde, toluene and so on in the air in an auto carriage; a temperature sensor performs real-time monitoring on ambient temperature which is then displayed on the display screen. When content or temperature of any gas exceeds alarm value, an alarm signal is given off, and a user is inquired whether to open a vehicle window for ventilation; if no reply is given after waiting for a period of time, the vehicle window is forced to be opened, thereby occurrence of danger is avoided. The invention can effectively avoid occurrence of intoxication or asphyxia accidents in the carriage and has very important use value.

Description

Technical field [0001] The invention belongs to the field of automobile electronics, and is specifically an automobile environment monitoring system based on air sensing technology and electronic control technology. technical background [0002] With the improvement of people's living standards, the penetration rate of automobiles is getting higher and higher. When people enjoy the great convenience brought by cars, they also pay a price for its negative effects. A report of the China Science and Technology International Environmental Technology Research Center on the automotive environment shows that there is serious pollution in the air inside the car. Toluene is the primary pollutant in the car's environment, followed by carbon monoxide and formaldehyde. The pollution of these harmful substances is relatively serious. If it is in contact with it for a long time, it will cause harm to the health of drivers and passengers. To make matters worse, there have been too many cases of...
