摘要
介绍了一种基于MSP430微处理器的便携式甲烷报警检测仪的设计与实现。仪器以催化燃烧式传感器为检测元件,可以准确地对甲烷浓度进行现场实时测量,并将测量结果及当前时间保存。当空气甲烷含量超过预设报警值时,采用声光报警。仪器具有与PC机通信的功能,通过串口可将保存的历史数据输出给PC机,通过管理软件实现历史数据的回顾与整理。仪器测量电路具有通用性,配合不同气敏元件适当调节参数就可实现对多种气体的测量。
A portable quantitative detector is designed for methane gas with thermal catalytic sensor. The detector based on MSP430 consists of analog signal regulation, human-machine interface, data storage and communication module. It can detect the gas concentration conveniently and in real time, and be configured by the buttons. The result can be displayed by LED and be saved in EEPROM at the same time, The resultalso can be transmitted to PC via UART for data storage and management. The detector has the functions of sound and light alarm, voltage monitoring, real-time display with the features of small size, high sensibility, quick response and portable,it can be used for multi-gas measurement by adjusting some data.
