【摘要】：农作物虫害常常对作物造成严重危害,使农业经济遭受损失。预测预报虫害的发生动态,可以使虫害防治工作得以有目的、有计划的进行,进而减少农业损失。传统的农作物虫害测报方法是由植保人员到田间以人工计数方式获得诱捕到的虫害数据。这种方式存在工作量大,效率低和精度差等问题,已经无法满足人们对虫害测报实时性和准确性的需求。随着信息技术的快速发展,越来越多的数据采集设备都安装有传感器模块和无线通信模块,使得数据从采集到无线传输都实现了自动化。本文根据农田现场数据采集和发送的特点,结合现有的技术水平,设计了一套适合野外工作的、高性能和方便虫害信息查看的智能虫害测报系统。系统利用生物性诱剂将害虫诱入具有特殊结构的捕虫器中,然后结合设计的双层红外传感器和温湿度传感器检测器,实现虫害和温湿度信息的采集和处理,将采集到的数据通过无线网络通信技术,存储到指定的服务器。本文设计的双层红外传感器能够有效的提高虫害统计的准确性,采用服务器存储和处理获取的数据,为测报人员提供Web网页端和App端两种方式获取实时测报信息。系统分为田间采集设备和应用服务两大部分。田间采集设备由虫害和温湿度信号采集节点和数据汇聚节点两部分组成。信号采集节点采用Microchip公司的PIC18F452芯片作为控制器,完成虫害信号和温湿度信号采集。采用成都亿佰特公司的E31-TTL-50 433M无线通信模块实现将数据发送至数据汇聚节点。汇聚节点采用SAMSUNG ARM11系列的S3C6410嵌入式微处理器作为核心器件,负责数据处理及通过GPRS网络向服务器发送数据。应用服务由Web网页和Android App两部分构成。测报人员可以通过网页或者App实时获取测报数据,及时有效的掌握田间虫害发生情况。本虫害测报系统不仅能够减轻测报人员的工作负担,而且使统计更准确,同时也使得测报工作更加简单便捷。
[Abstract]:Crop pests often cause serious damage to crops and cause losses to the agricultural economy. Forecasting the occurrence and dynamics of pests can enable the prevention and control of pests to be carried out in a purposeful and planned manner. In order to reduce agricultural losses, the traditional method of crop pest forecasting is to obtain the captured pest data by manual counting from plant protection personnel to the field. This method has many problems, such as heavy workload, low efficiency and poor precision, etc. With the rapid development of information technology, more and more data acquisition devices are equipped with sensor module and wireless communication module. According to the characteristics of field data acquisition and transmission, combined with the existing technical level, a set of field work is designed. Intelligent pest detection and reporting system with high performance and convenient viewing of pest information. The system uses biological attractant to lure insect pests into insect catcher with special structure, and then combines the designed double layer infrared sensor and temperature and humidity sensor detector, Through wireless network communication technology, the collected data can be stored to the designated server. The double-layer infrared sensor designed in this paper can effectively improve the accuracy of pest statistics. Using servers to store and process acquired data, The system is divided into two parts: field acquisition equipment and application service. Field acquisition equipment is composed of pest and temperature and humidity signal acquisition nodes and data collection. The signal acquisition node uses the PIC18F452 chip of Microchip company as the controller. The pest signal and temperature and humidity signal are collected. The E31-TTL-50 433M wireless communication module of Chengdu E31-TTL-50433M is used to transmit the data to the data convergence node. The sink node uses the S3C6410 embedded microprocessor of SAMSUNG ARM11 series as the core device. Responsible for data processing and sending data to server via GPRS network. Application service consists of two parts: Web web page and Android App. Surveyors can obtain real-time data through web page or App. The pest forecasting system can not only lighten the workload of the personnel, but also make the statistics more accurate, and make the forecasting work more simple and convenient.
