中文摘要：
为了在一个广阔区域中监测水质变化，需要布居多个智能传感器，采用无线数据传送是理想的数据汇总方式。分析比较了无线射频模块、GSM模块、GPRS模块的特性，给出了本地单片机与这3种模块进行连接的方法，以及如何通过这3种模块进行无线数据传送；同时也给出了在一种分布式系统中对终端数据信息的识别方法。所建立的基于无线传输的分布式水环境监测系统已投入试验应用。
英文摘要：
In order to monitor the water quality change in an expanse, many intelligent sensors need to be distributed. The ideal data summarizing method is wireless data transmission. The characteristics of wireless RF module, GSM module and GPRS module are analyzed and compared. The method to connect these modules to the local MCU is proposed, and the wireless data transmission through these wireless modules is also mentioned. The identification method of the terminal data information in the distributed system is introduced. The distributed water environment monitoring system based on wireless transmission has been put into the test and practice.
