摘　　要：设计了一种基于DSP控制的节水灌溉系统,用于实时监控土壤湿度状况,自动实现对土壤的节水灌溉。系统以TMS320C5402为核心,采用AQUA-TEL-TDR传感器的TDR原理,将输出的电信号通过MAX1246转化为数字信号;通过串口与PC机相连,PC机将计算出所需的灌溉量和时间并反馈给C5402,启动报警装置和开始灌溉。A water-saving irrigation control system based on DSP is presented, which can be applied to real-time monitoring for the soil moisture and also realize the automatic water-saving irrigation on Soil. The system is controlled by TM S320C5402, and adopts the TDP principle of the AQUA-TEL-TDR sensor to transfer the electrical signals into digital signals through MAX1246; moreover, through the serial port, it can be connected with PC which will calculate the required amount of irrigation and time, and then feedback them to C5402, finally, start the alarm device and begin to irrigate.
