摘要：根据现代化水产养殖的低耗高效的发展要求，设计了基于nRF905的水产养殖环境参数自动监控系统。该系统把监控中心PC机作为上位机，通过VB6.0构建上位机监控软件，同时以单片机MSP430作为下位机，并通过nRF905构建无线传感网络，从而实现自动监控系统的各项功能。经过试验，该自动监控系统能够对DO、pH进行实时的数据采集、显示和存储，并与增氧机结合对DO进行自动控制以及超限报警。养殖现场试验结果表明，该系统工作稳定、实时性好、能耗低，控制电路设计简单、成本低，有一定的应用推广价值和实际意义。

Abstract: To overcome the disadvantages of traditional monitoring methods on culture fisheries, such as time-consuming, high cost, low reliability and of the wiring complexity of wired monitoring system, an automatic monitoring system of aquacultural environment based on nRF905 was designed, according to the requirements of modern development of aquaculture. The system, used a personal computer as upper computer and Microprocessor MSP430 as lower computer, can realize the real-time data acquisition, as well as data display and storage of dissolved oxygen and pH value. At the same time, the system also provides automatic control and ultra limit alarming of dissolved oxygen .The upper computer monitoring software is built by VB6.0 and the upper computer. In addition, wireless sensor networks can be built by nRF905 and the lower computer. Test results proved that this system, which meets the development requirements of modern aquaculture, is reasonable, stable and easy.
