【摘要】：随着物联网、高精度传感器等技术的逐渐成熟,虫害测报的需求同样可以得到与时P6进的解决方案,传统的测报方案已经远远不能满足需要,自动化、智能化的虫害测报系统已经成为当前的迫切需要。针对这一现状,基于无线传感器网络,同时借鉴ZigBee星形网络拓扑结构下的入网协议理论,研制出一种虫害测报系统,该系统能够实时测量监测区域的温度和湿度以及虫害数据,实现数据的实时采集、处理、显示、存储和查询等功能。系统主要分为终端、网关、云服务器、客户端四个部分。实验结果分析表明,本文研究的基于无线传感器网络的虫害测报系统具有可行性和实用性。本文的研究内容如下:(1)终端节点由PIC单片机、数据采集模块,433MHz无线模块等组成,该节点负责将采集到的温湿度数据,虫害数据,存储到本节点中,同时通过433MHz无线模块自动发送至网关。(2)网关节点由STC单片机、433MHz无线模块和GPRS无线模块组成,该节点通过433MHz无线模块汇总终端节点采集到的数据,利用GPRS无线模块与云服务器中的网络调试助手建立TCP/IP连接,通过GPRS网络上传数据,达到了透明传输的效果。(3)云服务器以阿里云ECS为平台,包括网络调试助手、WampServer两部分,其中WampServer提供PHP运行环境及MySQL数据库。网络调试助手接收网关数据,以TXT文本格式保存,PHP动态读取TXT文本数据,将其转为字符串存储到MySQL数据库,同时响应客户端的数据请求。(4)客户端采用动态网页技术,动态获取数据库数据来刷新当前页面的湿度、温度和虫害数据以及终端节点ID等。虫害数据超过设置的阈值区间,系统自动启动报警功能,提醒测报人员要采取相应的灭虫措施。
[Abstract]:With the maturity of the Internet of things, high-precision sensors and other technologies, the demand for pest forecasting can also be solved with the time P6. The traditional forecasting scheme has been far from meeting the needs. Intelligent pest forecasting system has become an urgent need. In view of this situation, based on wireless sensor network and the theory of network access protocol based on ZigBee star network topology, a pest forecasting system is developed, which can measure the temperature, humidity and pest data in real time. Realize the real-time data collection, processing, display, storage and query functions. The system is divided into four parts: terminal, gateway, cloud server and client. The experimental results show that the pest forecasting system based on wireless sensor network is feasible and practical. The research contents of this paper are as follows: (1) the terminal node is composed of PIC single chip microcomputer, data acquisition module 433MHz wireless module and so on. The node is responsible for storing the collected temperature and humidity data and pest data into the node. At the same time, it is automatically sent to the gateway through 433MHz wireless module. (2) the gateway node is composed of STC single-chip microcomputer 433MHz wireless module and GPRS wireless module. The node aggregates the data collected by terminal node through 433MHz wireless module. Using GPRS wireless module and network debugging assistant in cloud server to establish TCP / IP connection, upload data through GPRS network, achieve the effect of transparent transmission. (3) the cloud server takes Ali cloud ECS as the platform, including two parts of network debugging assistant, WampServer, WampServer provides PHP running environment and MySQL database. The network debugging assistant receives the gateway data, saves the TXT text data in the form of TXT text, dynamically reads the TXT text data, stores the TXT text data into the MySQL database, and responds to the data request of the client. (4) the client adopts the dynamic web page technology. Dynamically obtain database data to refresh the current page humidity, temperature and pest data and terminal node ID. When the data of insect pests exceed the threshold range, the system automatically starts the alarm function and reminds the surveyors to take corresponding measures to control insects.
