Based On The Arm Network Of Intelligent Instrument Development And Research

With the rapid development of instrument industry and the requirements of recording instruments on intelligent and network, the recording instruments using in industrial control locate basing on embedded chips is an invariable trend. The new generation embedded chips have higher speed and abundant peripheral functions, which greatly shorten the exploiting cycle of new products. Also, the new generation chips embedded network interface supporting protocols.The embedded chip, s3c2410 of the arm9, is adopted in the study. It is 32 bits controller with RISC architecture and five-stage architecture. The S3c2410 have a rapid operate speed, the clock frequency of which is high to 204MHz. The need 6f a lot of complexity calculation is met. The s3c2410 have peripheral function modules of single-chip, especially the LCD controller, which can support monochrome , color and gray LCD. The displaying function of recording instrument is strengthened strongly, more visually. The controller allows addressing up to 4G byte, The requirement of paperless recording lots of data can be satisfied. The groundwork of the thesis is as follows,1. The architecture of embedded chip, arm ,has been studied and the system scheme of recorder with s3c2410 core has been designed.2. The embedded system model of development and process have been studied, the program realization of linux equipment and hardware system also has been tested.3. The digital filter has been analyzed and designed, the data have been analyzed with which.4. The TCP/IP protocol and designing of network communication with socket have been analyzed and been applied to system...
