设计一种基于GPRS的洪泽湖环境数据在线采集系统，以检测洪泽湖水质温度、pH和溶氧量为基础，使用SOPC技术在FPGA芯片上构建一个Nios II微处理器及其外围电路的接口电路，从而形成一个与系统任务需求相一致的自定义微处理器系统。由Nios II微处理器将使用Modbus协议读取的水质温度、pH和溶氧量参数经过协议转换后送GPRS移动数据传输模块进行数据远传，同时远程数据采集服务器将其以数值和波形方式进行显示。这种无线数据采集方式的建设、运营成本低，监控范围宽，实时性高，而NiosII微处理器的构建使得整个系统易于升级换代，能更好地满足水环境监测的需求。

The environment online data acquisition system of Hongze Lake based on GPRS was designed based on detecting the temperature, pH and dissolved oxygen of water, and using SOPC technology in a FPGA chip to construct a NiosII micro-processor and its peripheral interface circuit. A custom microprocessor system consistent with the task demand of system was formed. After the NiosII microprocessor converted temperature, pH and dissolved oxygen parameters read by the Modbus pro-tocol, the data were sent to GPRS mobile data transmission module for data transmission, and displayed in numerical and waveform by remote data acquisition server. The wireless data acquisition mode’ construction and operation cost was low, with advantages of wide monitoring range, high real-time performance. The construction of NiosII microprocessor made the system easy to upgrade, which could better meet the requirements of water environment monitoring.
