基于单片机的实时农药混合控制系统设计

Design of Real-time Pesticide Mixture Control System Based on Microcontroller

针对传统农药喷洒时人工一次性将农药混合后喷洒存在易发生人员中毒、混合比例精度差、长时间喷洒药效降低、农药浪费的问题,以单片机技术为核心,结合传感器、遥控技术,设计一种具有参数设定、药液流量实时采集显示、调节及药液实时混合等功能的控制系统。经试验,该系统工作可靠、控制精度高、成本低廉,能够根据农作物施药需求实时、按比例进行农药混合,能够降低人员中毒风险、提高药效,具有较好的应用价值。

Against on prone to poisoning,Low hybrid precision,Long time spraying with low drug effect,Pesticide waste in Artificial disposable pesticide mixture,the paper designed a control system which put single chip technology as core and combined humidity sensor and remote control,it had some functions such as parameter setting,real-time display,liquid flow adjustment and real-time pesticide mixture etc.The test results show that the system with the advantages of good stabilization,better control performance,low cost,according to crop demand pesticide mixtured real-timely and in proportion,reduce personnel poisoning probability and pesticide efficac improved,it has a good application value.
