摘　　要：以微处理器ADuC841为控制器,设计了CO气体浓度检测系统。它具有现场气体浓度液晶显示、声光报警、报警限设定等功能。介绍了系统工作原理和各组成部分的电路设计。对气体传感器进行了温度补偿,能够抑制环境温度变化对传感器的干扰。系统具有精度高、体积小、工作稳定、硬件结构简单等特点。利用无线收发模块PTR2000进行数据的无线传输,实现微处理器与PC机之间的无线通信,降低了布线成本,提高了系统的灵活性和可扩展性。The ADuC841 was used as the microcontroller to design the detection system of CO gas. It has the functions of gas concentration display, sound and light alarm, setting up alarm limit. The operation principal, the circuit design was introduced. Temperature compensation was made for gas sensor, the temperature interfere can be restrained. The system has the advantages of high precision, small volume, steady property and simple hardware. The sensor can transmit and receive the data by wireless data transceiver PTR2000, the wireless communication between the microcontroller and the computer was realized. It can reduce the cost of wiring and improve the adaptability and extensibility of the system.
