基于GSM的远程空气质量监测系统设计

Design of the Remote Air Quality Monitor System Based on GSM

由于人们环保意识的提高,越来越多的场合期望提供实时的空气质量监测数据。对于这类应用场景,基于无线网络的远端监测站点与数据处理中心的系统架构已经十分成熟。给出了基于信号覆盖率最高的GSM中最可靠的短信服务作为数据传输媒介的远程空气质量监测系统的设计方案。方案中的硬件选型以性能、尺寸和功耗同时作为标准,力求使得系统具有更佳的工程使用价值,方便日后推广。同时监测中心除提供基本的监测软件外,还提供了开发库,便于用户利用监测站点的数据进行二次开发。通过对原型机的测试,该设计能够在无外部电源供电的情况下连续72h对空气质量进行监测,具有实用推广价值。

Due to the improvement of people's environmental awareness,more and more situations are expected to provide real-time air quality monitor data.For this kind of applications,the system architecture with remote monitor stations connecting to the data process center via wireless networks has been mature.A design of the remote air quality monitor system based on the short message service which is most reliable in GSM with the highest coverage rate of signal is presented in this paper.Performance,size,and power consumption are the factors that affect the selection for the hardware in the proposed design,which makes the system a higher engineering value and facilitates the promotion of this system.The monitor center provides basic monitor software and software development kit in the meantime,which can help the users with their secondary development.The design can report the air quality monitor data for 72 hours without external power supply in the test of the prototype,and is worth promotion.
