基于ARM11的嵌入式远程无线环境监测系统的设计

摘要：温湿度采集传感技术和GPRS无线传输技术应用广泛，已经应用到了工业，农业等各个领域。随着我国经济的发展，环境问题日益突出，环境保护应以预防为主治理为辅，我们应把计算机技术与环境保护相结合，根据环境监测数据提出相应的治理方案。本系统使用分为监测主机和监测从机，主机使用ARM11处理器和Linux系统，从机使用Cortex-M3核的微控制器。从机采集数据后通过GPRS 回传到主机进行显示。

主机是一台基于S3C6410处理器的单板，除处理器外还有内存、FLASH以及网卡芯片，主机运行Linux操作系统，使用Qt Creator编写程序，然后使用交叉编译工具arm-linux-gcc编译成ARM版本的可执行文件，然后拷贝到单板上运行，主机的数据存储使用的是轻量级数据库SQLITE，可供查看以往的记录信息，主机使用以太网接收从机传来的温湿度信息。从机是以LPC1768微控制器为主控的专用温湿度采集系统，传感器是DHT22，DHT22是一款集成采集温度度功能于一体的传感器，传感器采集完温湿度后通过GPRS通道传给上位机，GPRS 芯片使用的是SIM900，这是一款工业级的手机模块芯片。

本文首先给出了设计的原理和设计思路，然后根据软硬件分章介绍各自的设计原理以及实现过程，从而设计一个高稳定性的环境监测系统，实现环境温湿度的在线实时监测。

Design of Embeded Wireless and Remote Environment Moni toring System Based on ARM11

Abstract: Temperature and humidity sensor technology capture a wide range of technology applications, and so does GPRS wireless transmission. The accordingly technologies have been applied to various fields of industry, agriculture and so on. As China's economic development, environmental issues have bee increasingly prominent, environmental governance should be based on prevention supplement, we should bine puter technology and environmental protection, propose appropriate governance program based on environmental monitoring data. The system is divided into monitoring the use and monitoring from the host machine, the host uses ARM11 processor and Linux systems, the slave using Cortex-M3 microcontroller core. Data collected from the machine back to the host via GPRS display.

Host-based S3C6410 processor is a single-board, in addition to the processor but also have memory, FLASH and chip card, the host uses the Linux operating system, using Qt Creator programming on Linux systems, and then use cross-pilation tools piled into ARM version executable file, then copy it to run a single board, the master data store using a lightweight database SQLITE, available for viewing previous record information, the host uses Ethernet receive information from the machine temperature and humidity ing. Slave is based on the special temperature and humidity acquisition system LPC1768 microcontroller, sensors using DHT22, DHT22 is an integrated collection of functions in one degree of temperature sensors, temperature and humidity after the pletion of the acquisition sensor to the host puter via GPRS channel, GPRS chip using SIM900, which is an industrial-grade mobile phone module chip.

This paper first gives the design principles and design ideas, and then present their design and implementation process in accordance with the principles of the hardware and software sub-chapter to design a high stability of the environmental monitoring system, online real-time monitoring of temperature and humidity.
