摘要
采用自动控制技术实现节水灌溉是当今的发展方向之一。该文给出了节水灌溉自动化系统中的无线数据采集子系统、节水灌溉自动控制子系统、系统控制软件结构设计和抗干扰措施。利用nRF903收/发芯片实现数据的无线传输,采集端将传感器的输出信号进行模数转换,利用无线数字传输技术将数据发送到接收端,在接收端对数据进行存储和显示。该文从硬件和软件两方面描述了系统的设计及实现方法。实践证明,该系统使用灵活,数据传输可靠,更适合不便连线的测试和控制场合应用。
It is one of directions nowadays to combine automatic control technology with water saving irrigation. In this paper, a wireless data acquisition subsystem of water saving irrigation automatic control, auto-control subsystem, design of software structure and methods of anti-jamming were introduced. The nRF903 single chip RF transceiver was employed to modulate and demodulate for data transfer. It is made up of two separated parts: collection and receiving. The collection part digitalizes the signal from the sensor and sends it out using wireless digital transmission technology. At the receiving part, the data were received, saved and displayed. Hardware and software of the system were described in this paper. Experiment shows that the system is reliable and suitable for those testing situation in convenient for cable connection.
