基于ZigBee与RFID的苹果果园信息采集系统：系统设计与构建

Apple Orchard Information Collection System Based on ZigBee and RFID: System Design and Construction

摘要: 随着农业信息化和无线通讯技术的发展，利用便携式智能设备采集农田信息正在成为一种重要手段。为了解决果园信息采集问题，本文开发了一个基于ZigBee与RFID的苹果果园信息采集系统。系统硬件部分由PDA、ZigBee协调器模块(连接ZigBee无线传感器网络)、RFID模块以及服务器等组成。系统软件部分包括一个运行于PDA端的嵌入式果园信息采集系统以及一个运行于服务器端的远程服务器端果园数据交换系统。无线便携终端PDA阅读果树RFID信息，确定数据采集果树对象，通过集成于PDA的ZigBee协调器采集该果树周围布设的ZigBee无线传感器网络获取的信息(果树生长环境、果树生长状态以及传感器本身工作参数)，随后即可使用自定义的数据交换协议将采集数据发送至服务器，同时更新PDA端显示。服务器端接收数据后，保存到相应数据库并返回结果反馈信息。试运行表明，系统工作稳定，运行可靠，可实现果园果树数据的采集与保存，为后续数据分析提供服务，在农业生产领域具有一定的使用和推广价值。

Abstract: With the development of agricultural information technology and wireless communication technology, the use of portable intelligent equipment to collect farm information is becoming an important means. In order to solve the problem of orchard information collection, an apple orchard information acquisition system based on ZigBee and RFID was developed in this paper. The hard-ware part of the system is composed of PDA, ZigBee coordinator module (connecting ZigBee wireless sensor network), RFID module and server. The software part of the system includes an embedded orchard information collection system running on the PDA side and a remote server terminal data exchange system running on the server side. The wireless portable terminal PDA reads the fruit tree RFID information, determines the data to collect the fruit tree objects, and collects the information obtained by the ZigBee wireless sensor network arranged around the fruit tree (the fruit tree growth environment, the fruit tree growth state and the sensor itself parameters) through the ZigBee coordinator integrated in the PDA, and then the custom can be used. The data exchange protocol sends the collected data to the server and updates the PDA display. After the server receives the data, it saves it to the corresponding database and returns the feedback information. The trial operation shows that the system is stable and reliable, and can realize the collection and preservation of the orchard fruit tree data, provide service for the follow-up data analysis, and have a certain use and promotion value in the field of agricultural production.
