Research And Implemention Of The Environment Monitoring System Based On ARM11

With modern science and technology information and the rapid development of embedded system, environment monitoring system in the military, health care, communications, industrial and agricultural and People’s Daily life medium widely of development, management more scientific, humanization, intelligent, also make the people’s living standards improved. China’s urbanization process more and more quickly, city building more and more high, high building fire hazard gradually exposed. At present some simple household life-saving equipment is already can’t satisfy people’s needs, in order to people’s lives and property security, we focused on home and office design developed a "intelligent electronic insurance tank" electronic system survival equipment, for people in the event of fire, earthquake and an emergency escape. With the rapid development of modern science and technology and intelligent, people in the cabin to insurance function and its environment, information processing humanization, intelligentized continuously improve and promote the first generation of home/business escape product "intelligent electronic insurance class" was born.This article in this insurance tank under the background of the electronic system, introduces a kind of ARM11based on hardware platform of the microprocessor S3C6410, configuration software platform and Qt embedded Linux applications of environment monitoring system research and implementation. The monitoring system of collection devices such as sensors, camera, gas flow meter instruments will air pressure, temperature, video image data by a machine spread to the control center, the control center will these data to indicate to the touch screen, the user can through the touch screen terminals, to achieve the purpose of real-time monitoring.This environment monitoring system mainly divided into temperature and pressure control system, cooling system, gas supply system, video acquisition module and power management system five part, mainly complete functions include:through the air pressure, the temperature sensor real-time monitoring the cabin pressure and temperature change, automatic control exhaust and refrigeration system; Through the camera outside the cabin of the fire for video images in real time monitoring and transmission; Through the gas flow meter monitoring supply of gas gas flow so as to control the flow of the electromagnetic valve size.This paper first analyzes the advantages of embedded Linux ARM processor and the comparison of the series, finally choosing S3C6410processor as the core of the system and embedded processor of Linux operating system; And then put forward the system mainly completes environment monitoring function and system of the hardware and software system structure; And the system the realization of the function of each module in the detailed design of points analysis, each module is from a machine under the circuit design to PC software process design in detail; Finally realized by the system, the PC and development board operation commissioning, the test show that the development system can satisfy the design requirement, achieved the desired results, and man-machine interface is good.
