摘要
为实现基于S3C6410和STM32的无线节水滴灌自动控制系统的设计方法,重点研究设计了田间控制器。系统利用ZigBee无线传感器网络的自组网特点,采用星型网络拓扑结构,实时监控多块田地的土壤温湿度变化,通过反馈传感信号,对滴灌动作进行精准判断和控制。田间试验期间测得土壤湿度最小值为30%,最大值为70%,处于理想范围内。实验结果表明,系统能够实现滴灌自动控制,且性能良好,具有灵活性强、安全可靠、低功耗、低成本、移植性好等特点。
In order to realize a design method of the wireless automatic drip irrigation system based on S3C6410 and STM32 MCU,a field controller is designed emphatically. According to the self-organization characteristics of ZigBee wireless sensor network,the star network topology structure is adopted to monitor the change of soil temperature and humidity,and make accurate control and judgement on the drip action by the feedback of the sensor signal. The soil moisture got during field experi-ment is 30%~70%,which is in the ideal range. The experiment results show that the system is of good performance,can realize auto control of the drip irrigation. Furthermore the system has the characteristics of high flexibility,safe reliability,low power consumption,low cost and good portability.
