摘要
针对卫生防疫和劳动卫生保护部门对公共场所及有关生产车间CO气体浓度监测要求,给出了一种具有GSM短消息收发功能的低功耗CO气体浓度监测仪设计方案,降低了监测仪功耗的同时,也延长了电池的供电周期.讨论了单片机工作方式选择、电源供给、元器件选取及TC35模块的管理等硬件设计问题及低功耗应用系统软件设计应采取的措施.
Facing the requirement of detecting CO gas density in public place＇s and related workrooms produced by hygiene epidemic prevention and labor hygiene protection departments, this paper gives a kind of design scheme of low power consumption of CO gas density monitor with GSM short messages receiving and transmitting function. Discussing the hardware design problems in detail, such as the selection of work state of singlechip microcomputer, the supply model of power, the component selecting, the management of TC35 module and so on. In software design it also gives the measurements of low power consumption applied system.
