自动追踪式太阳能虫害监测仪控制设计

摘要

This paper introduced the basic functions and working characteristics of the automatic tracking solar pest monitor,and emphatically expounded its hardware structure,control principle,data collection and transmission,data analysis,etc.PLC and GPRS combined with solar photovoltaic and micro sensor were used for pest monitoring.The host computer was the configuration software served as master station and the slave computer PLC was served as slave station.Through the DTU data transmission or data link,the data collected by the sensor was converted and stored in the corresponding PLC data acquisition area,and the host computer can directly read the data from the data acquisition area through the DTU.By testing the application effect,the device had the advantages of easy operation,high sensitivity,low energy consumption,clear and readable observation interface,which can monitor common types of insects in experiment area.It can be widely used in places where pests outbreak frequently,network delay can be negligible and no need to do atlas analysis of monitoring pests.The device can provide data reference for pest control in crops of agriculture and forest,but there still needed a further study on the sensor precision control problem.%介绍其自动追踪式太阳能虫害监测仪的基本功能和工作特点,着重阐述其硬件构成、控制原理、数据的采集传输和读取分析等.应用PLC技术和GPRS技术,结合太阳能光伏技术和微量传感技术对虫害进行监测.上位机为组态软件设为主站,下位机PLC相当于从站,通过DTU进行数据传输或数据链接,将传感器采集的数据转换后储存在PLC相应的数据采集区,上位机可直接通过DTU从数据采集区读取相应的监测数据.经试验测试其应用效果,仪器易于操作、灵敏度高、耗能低,观测界面清晰、可读性强,可监测到试验区常见的各类飞虫,能广泛适用于易爆发虫灾、可忽略网络延迟、无需对监测害虫进行图谱分析的区域.可为农林作物的虫害防治工作提供数据参考,但仍需对传感器精度控制问题作进一步研究.
