摘　　要：现代农业相较于传统农业,其自动化、及时性、精确度等要求更高,对目标环境需要多点全天候监测才能做到精确控制。为此,采用多个SHT75温湿度传感器进行多点环境数据采集,并由从控制器MSP430处理后经RS-485总线转发至上位机。上位机对多个从控制器的数据统一处理后,实现超限短信报警,环境自动调节等功能。经实际测试,本系统具有测量精度高、能耗较低、稳定性好等优点。Compared with traditional agriculture, modern agriculture has a higher requirement for automation,real time and accuracy. Multi-point all-weather monitoring is necessary to achieve an accurate control over the target environment. For this aim,multiple SHT75 sensors of temperature and humidity are adopted to implement multi-point environment data acquisition. After the processing of MSP430 controllers,the data are transferred to the host computer by RS-485 bus. Then the host computer processes all the data from the controllers,fulfilling the functions of transfinite SMS alarm and automatic environmental adjustment. By the actual experiments,it proved that this system has the advantages of high measuring precision,low energy consumption,reliable stability,etc.
