园林移动施药实时监测系统设计与试验

由于园林作物复杂,对不同植物病虫害需要的施药量以及药品类型不同,为实现实时监测,做好园林植保作业,本文以STM32F103VCT6单片机为信息处理控制器,设计园林移动施药实时监测系统,并通过车体结构设计,构建监测施药作业体系。系统由移动车体、药箱、微控制器、GPS定位系统、GSM无线通信模块、液位传感器、流量传感器、显示屏和按键构成。基于多信息融合技术,系统实现了对植保车行驶轨迹、车速、施药流量和药液余量等信息的实时监测,以量化小车在不同的位置喷洒药液的情况。试验结果表明:轨迹监测平均误差为4.75%;施药速度监测平均误差为2.17%;流量监测平均误差为1.54%;液位监测平均误差为0.44%,本研究对于园林移动施药参数实时监测提供了理论依据与应用参考。

Design and test of monitoring system for garden mobile spray application

Due to the complexity of garden crops,the amount and type of drugs required for different plant diseases and insect pests are different.In order to realize real-time monitoring of plant protection of various plant diseases and insect pests,the situation of plant protection operation is monitored in real time.Aiming at mobile spray in garden pest and disease control,this paper designed a monitoring system for garden mobile spray application based on single chip microcomputer STM32F103VCT6.The system included moving car,medicine cabinet,microcontroller,GPS positioning system,GSM wireless communication module,liquid level sensor,flow sensor,display screen and buttons.A set of real-time monitoring system of mobile spray was developed by designing in view of the multi-information fusion technology based on single chip microcomputer.And the system realized the real-time monitoring of information such as track,speed,spray volume and liquid residue through the design of software and hardware.By using the mobile spray system,experimental studies of track monitoring,spray speed monitoring,spray volume monitoring,and liquid residue monitoring at different position were carried out.Results showed that the mean deviation of track monitoring is within 4.75%,the mean deviation of spray speed monitoring was 2.17%,the mean deviation of spray volume monitoring was 1.54%,and the average deviation of liquid level monitoring was 0.44%.The results from this paper provide a case study showing how to monitor mobile spraying application effectively in garden by using proper sciences and technologies.
