【摘要】 针对我国主要的水质监测系统存在水质采样能力弱、数据处理不及时、缺乏水质变化预警机制等问题,提出了一种基于通用分组无线业务(GPRS)技术的水质自动监测系统设计方案。阐述了系统组成,重点介绍了GPRS模块的工作过程与监控中心子系统的通信部分。同时,对水质采集子系统的软件设计进行了阐述,提出多状态、多任务、多线程的软件设计思想,详细分析了GPRS模块流程,实现了系统功能。测试表明:系统性能稳定,时效性好,运行成本低,适合水质监测需要。更多还原

【Abstract】 In response to the problems in Chinese major monitoring system of water quality such as weak sampling capability of water quality,untimely data processing and lack of early warning mechanism of water quality change,based on GPRS technology,the design scheme of an automatic water quality monitoring system is proposed.The system composition is described,and the working process of GPRS module,together with the key part of the sub-system of monitoring center is introduced.The software design of the sub-system of water quality collection is explained,the multi-state,multi-task,multithreading software designing idea is advanced.The GPRS module flow is analyzed and the systematic function is achieved.Tests show that the system has stable performance,good timeliness and low operation cost,which can meet the need of water quality monitoring under the new situation.更多还原
