摘　　要：猪舍的环境对生猪生长和养殖场的经济效益有很大影响。针对养殖环境参数监测过程中存在有建筑物影响,考虑定向天线具有传输距离远、增益高、抗干扰性特点,该文设计了一款基于定向天线适用于生猪养殖环境监测的无线传感网络。节点以传感器节点以MSP430系列单片机作为主控芯片,无线通信采用nRF905射频模块,温湿度采用SHT11数字传感器,有害气体检测采用H2S和NH3传感器,并以该节点为硬件平台编写了通信协议、应用程序和后台管理软件。试验结果表明,该系统性能稳定,传感精度及其环境自动调控均达到实际应用需求。Pig farm＇s environment has great impact on economic efficiency of pig growth. As there is affection of buildings in the breeding environment monitoring, a wireless sensor network （WSN） was developed considering the characteristics of directional antenna which are far transmission distance, high gain, and noise immunity. The node used MSP430 MCU as the core, nRFg05 as wireless communication module, SHTll digital temperature as temperature sensors, and H2S and NH3 sensors for detecting harmful gases. The communication protocol, application program and background man- agement software were compiled and embedded into the node. The experimental results show that the performance of the system is quite stable, and the measurement precision and environmental automatic control could meet the needs of data acquisition.
