    摘要:

    为提高温室管理水平,针对有线系统监测布线不灵活或长时无人监测和无线系统数据传输不稳定等问题,设计一种基于GSM技术具有远程交互功能的土壤湿度监控系统。该系统由MSP430控制器、GSM模块灌溉控制电路等组成。通过GSM模块以短信的方式实现与用户之间的交互功能,并利用模糊控制算法进行精确灌溉。运行试验结果表明:设计的系统工作稳定,数据传输距离不受限,节水灌溉效果显著,GSM模块收发信息的正确率达100%;接收数据正确率达98.73%,实时监控灌溉性能稳定; 能够实现精确灌溉,与人工漫灌相比节省20%~30%的用水量,节水效果显著。

    Abstract:

    Due to the fact that the wiring and long-term unattended monitoring is inconvenient, a system was designed by using the remote control of soil moisture, in order to improve the production management level of the greenhouse. This system contains a MSP430 controller, a GSM module, and a solar power module and irrigation control circuit. The interaction between the environmental factors and the users was achieved by the GSM module, and the precision irrigation was implemented by using the fuzzy control algorithm. The actual operating test shows that the system is stable, the data transmission distance is unlimited, the effect of water-saving was apparent, the GSM module sends messages whose accurate rate can be up to 100%, and it is capable of receiving 98.73% of the data accurately. It also shows that this system can realize precision irrigation, it economizes 20%-30% of the water compared with the flood irrigation.
