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成为一种重要的手段。为了解决果园信息无线采集的问题，我们开发了一个基于Android PDA的系统。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接口。无线便携终端PDA通过ZigBee协调器采集ZigBee无线传感器网络上传信息(果树生长环境、生长状态、以及传感器本身工作状态等)，然后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，保存到数据库并返回结果。试运行表明，系统工作稳定，运行可靠，可实现数据的采集与保存，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 informatization and wireless communication technology, utilization of portable intelligent devices for data collection is becoming an imperative approach. In order to collect information of fruit trees in the orchard using movable device, a system based on Android PDA was developed. The system hardware consists of PDA, ZigBee coordinator module (to connect ZigBee wireless sensors network), RFID module and orchard server. On the other hand, the system software is made up of a data acquisition system running on the PDA and an orchard data exchanging interface running on the remote server. The wireless portable terminal, that is, the PDA collects the information of the fruit trees' growing environment, growing condition, and the sensor’s own working condition. Then PDA sends data to server through a customized data exchanging protocol, updating PDA-side display simultaneously. Once the server receives the data, the server saves it to the MySQL database and returns results to the PDA. System test running indicates that the system is stable and reliable enough and it can be used to collect the data from orchard. Hence it can provide further service for subsequent data analysis. Overall, the whole system has a certain value of utilizitionality and proliferation in the field of agricultural production.
