Design Of Distributed Long Distance Multi-parameters Environment Detecting System Based On ARM

With the development of economy, advancement of the society and improvement of people's environment protection consciousness, the problem of environment quality is more and more concerned by the public. However, the development of environment detecting can not meet the environment detecting requirements, most of them has low quality and less functions. The major problems that environment detecting faced are how to improve the precision of parameters, multiple detecting technologies, and how to make correct assessment to environment pollution status.The thesis try to design a distributed long distance multi-parameter detecting system. We realize distributed long distance multi-parameter detecting system with low cost , by using embedded system, sensor , auto-detecting , communication , network and micro-computer technologies. The research point of this thesis manly include:1. Analyzing the current research status of national environment detecting, giving a new design project of distributed long distance multi-parameter detecting system. According to the designing, the system is mainly consist of host equipment, assistant equipment and tele-detecting PC.2. Complete the hardware designing about the distributed long distance multi-parameter detecting system. The host equipment use S3C44B0X as core chip which based on ARM7TDMI kernel, designing FLASH storage module, SDRAM module, UART module and Ethernet module. All of the main chips are small scale and low power consumption, which are fit for the application of embedded system production.3. Complete the software designing about the distributed long distance multi-parameter detecting system. The host equipment transplants embedded system uClinux and JFFS2 file system, developing the device programs and application programs. The assistant equipment use data collecting programs to gather the environment parameters, the program for tele-communication was also designed.4. Build the long distance detecting system based on Boa embedded server. The host equipment transplants Boa embedded server. We realize the networklization and long distance of detecting by using Boa and CGI structure.The system developed characteristic as good expansibility and flexibility . By using wireless module, the range of detecting has great improved. Web server realize the system networklization. The anticipated function being realized by module debug and system debug.
