无线环境监测技术广泛应用于环境、医疗、工业、农业和家庭办公等领域，由于传统的环境监测系统存在很多缺陷，例如安装维护复杂、多点布线困难等问题，应用新技术替代传统环境监测系统的趋势显得尤为突出。近年来，因无线传感器网络技术（WSN）的传感器节点成本低、功耗低、容易布局且网络容量大等优点非常适合应用于环境监测系统，尤其是在一些偏远地区、布线困难和多传感节点的场合中，本文的选题背景即是针对环境监测领域中的禽舍环境监测。 本文在分析了无线传感器网络监测系统、嵌入式ARM+Linux技术的发展现状的基础上，提出并设计了一种基于ZigBee传感器网络技术和ARM11平台的远程环境信息监测系统。该系统主要由负责数据采集和传输的ZigBee网络与负责数据处理、存储和显示的嵌入式网关组成。ZigBee网络中ZigBee模块由主控模块（MCU）、传感模块、无线传输模块等硬件组成，在此基础上设计了基于Z-Stack协议栈的ZigBee协调器节点和传感器节点的软件。嵌入式网关的硬件平台由ARM11构成，在该硬件平台上移植了由Bootloader、Linux内核和根文件系统组成的嵌入式Linux操作系统，在Linux系统之上搭建了由Boa和CGI构成的嵌入式Web服务器与嵌入式数据库SQLite。利用HTML和CGI技术制作了用于人机交互的服务器界面，最后利用Linux串口通信和CGI设计了嵌入式网关的数据处理程序。用户可通过Web浏览器登陆服务器并进行环境数据的实时查询。 该系统具有良好的人机交互界面和远程访问的功能，与此同时，ZigBee模块可扩展性较强，可随时接入不同的传感器设备，如温湿度传感器、气体浓度传感器等。通过对本系统各项功能的测试，结果表明该系统能够满足功能需求，且准确性和稳定性较好。

Wireless environmental monitoring technology is widely applied to environmental, medical, industrial, agricultural, and family & office sectors. Multiple defects with the traditional environmental monitoring system, such as complicated installation and maintenance and difficulty with multipoint wiring, accentuate the trend of using new technologies to replace the traditional system. The recently appeared WSN, because of its low cost, low power consumption, layout convenience, and high network capacity, provides an ideal solution in environmental monitoring systems, particularly in some remote regions and areas where wire layout is a challenging task or where multiple sensing nodes are desired. This paper studies as its subject the monitoring of poultry houses in the environmental monitoring field. Following an analysis of the current development situation of wireless sensor network monitoring system and embedded ARM+Linux technologies, this paper comes up with a design of remote environmental information monitoring system based on ZigBee sensor network technology and ARM11 platform. This system consists largely of a ZigBee network, which is responsible for data acquisition and transmission, and imbedded gateways, which are responsible for data processing, storage, and display. A ZigBee module in the ZigBee network is composed of such hardware as an MCU, a sensing module, and a wireless transmission module, on the basis of which Z-Stack protocol stack-based software is developed for ZigBee coordinators and sensor nodes. The embedded gateway hardware platform is made up of ARM11, to this hardware platform is transplanted an embedded Linux OS consisting of Bootloader, Linux kernel, and root file system, and in turn on the Linux OS is created an embedded Web server and an embedded database SQLite consisting of Boa and CGI. HTML and CGI technologies are employed to make a server interface for human-computer interaction application and, finally, an embedded gateway data processing program is written using Linux serial port communication and CGI. A user may log on to the server and make real-time inquiry about environmental data. This system features good HCIs and remote accessing functions and, additionally, its ZigBee modules are highly scalable, ready to accommodate different sensor devices, such as temperature sensor, gas concentration sensor, etc. The system was tested to verify its functions, and the test results demonstrated that this system satisfies the functional requirements and is accurate and reliable.
