1、基于GPRS的水质参数监测系统设计---单片机msp430的硬件设计设计总说明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，设计了基于GPRS和MSP430F149单片机的水质实时远程监测系统。该系统通过数据采集模块传感器采集到水质数据信息后经放大处理后传给单片机，经过单片机的处理，通过GPRS将实时监测到的水质状况传到监测信息处理中心，使监测中心工作人员足不出户即能掌握辖区水质信息，从而使监测中心的管理在机制上实现从人工化向信息化的转变，克服了过去对各
2、项水质指标的监测主要靠工作人员到现场手工取样，带回实验室分析后再作出结论，周期长、效率低的问题，还可以提高对水质的监测频次，克服过去由于监测频次低，所造成的后果是总结出来的水质参数可信度较低，该系统不仅能自动监测水质参数，结构简单、成本低，而且能及时发送监测数据，不必人工干预，特别适合天气变化比较复杂和无人值守的情况，有效地提高了水资源的利用率，有较好的推广应用价值。关键词：GPRS；MSP430F149；单片机；实时监测；传感器BasedontheWaterQualityParametersof
