基于MSP430的汽车尾气浓度监控系统设计

Design of Automobile Exhaust Concentration Monitoring System Based on MSP430

为了对城市道路上汽车尾气含量进行实时精确监控,介绍了一种以MSP430F149为控制核心的汽车尾气浓度实时监控设计方案.该设计主要由路况空气质量传感器检测模块、数据处理模块、液晶显示模块及声光告警模块等组成.可实现对道路上空气中还原性污染分子浓度的实时采集和显示,键盘设置报警阈值以及尾气浓度超标声光报警等功能,具有超低功耗、对低浓度污染气体灵敏度高、寿命长、成本低、实时性好、应用前景广泛等优点.

This paper puts forward a real-time monitoring system for automobile exhaust concentration based on the MSP430F149 MCU to real-time accurate monitoring the city road automobile exhaust content. This system is mainly composed of traffic air quality sensor detection module, data processing module and sound- light alarm module, which can realize the real-time acquisition and display for reducing pollution of molecular concentration in the air on the road,keyboard sets alarm threshold, alarm for the exceed automobile exhaust concentration. The system has the advantages of ultra-low power, with high sensitivity for the low concentra- tion of pollutant gases, long service life, low cost, real-time measuring and wide application.
