摘要
为了提高现代化工业城市中水资源的管理水平,以Xmega256A3低功耗微控制器为平台,利用无线GPRS网络,提出了一种应用于水表集抄系统的数据采集通讯终端的设计方案。详细介绍了低功耗嵌入式平台的设计及其软件处理方式,并对试验数据进行分析,估计终端在长时间电池供电下运行的可靠性。实验结果表明,该设计的功耗和稳定性都达到应用要求,在自来水自动化管理中得到广泛应用。
To improve the management of water source in industrial cities, a design of data collection and communication terminal of water meter applicated to AMR system is proposed, which uses a low power consume platform of Xmega256A3 and GPRS. The design of embedded platform with low power consumption and its software management are specifically introduced. Then, the test data are analyzed and the reliability of long running under the battery supply is estimated. It is proved in experiments that its power consumption and reliability have met the requirement in application and it has been applied to automatic management of water extensively.
