车载网络传感器采集监控系统的设计

Design of in-vehicle network sensor acquisition monitoring system

为解决车室内空气污染问题,设计了一种车载网络气体传感器数据采集监控系统,它可以及时反馈和处理信息,以保证采集信号的实时性和快速性,如果车室气体体积分数超出正常体积分数范围时,系统启动报警和空调控制,并及时对车室换风补充新鲜空气。主要介绍了模数转换器AD7862的性能、工作时序,气体传感器模块和信号采集系统硬件设计,并对系统软件设计程序进行调试和数据的验证分析。该研究对汽车车室环境中空气质量的监控和人身安全等问题具有十分重要的意义。

An in-vehicle network gas sensor data acquisition monitoring system was designed to solve the problem of air pollution. It can timely feedback and deal with information to ensure real-time and quickly gather signal. If the volume fraction in vehicle exceed normal range, the system will activate alarm and air-conditioning control that add the wind of fresh air. The performance and job timing of the ADC7862 are described. Gas sensor module and design of hardware signal acquisition system is introduced. Then the design of system software is debugged and data is analyzed and verified. This study provides a great significance for air quality monitoring in-vehicle environment personal security and other issues.
