摘要
研究设计了一种具有检测和超限报警功能的空气酒精浓度监测仪。该设计方案在无操作系统环境下采用FS2410开发板,MQ-3酒精传感器,通过S3C2410处理器控制各个功能模块。系统将传感器输出的模拟信号输入ADC进行A/D模数转换,再进行数据处理,通过LCD显示。当酒精浓度超限时,蜂鸣器报警。文中详细介绍了系统硬件电路设计和软件设计的方法。
The author designs an air alcohol concentration monitoring device with detection and over-limit alarm functions. The design is without operating system environment and uses FS2410 development board, MQ-3 alcohol sensor, and control the various functional modules through S3C2410 processor. In this system, the sensor outputing analog signal input to ADC for A/ D analog-digital conversion, then processing the data and through the LCD display. When the alcohol concentration overrun, the buzzer alarm. The paper details the hardware circuit desig, n and software design.
