基于ARM的GPRS无线数据传输系统的研究
Wireless data transmission based on ARM and GPRS
摘要
Abstract
According to the remote wireless data transmission requirements, a kind of GPRS remote data transmission scheme based on ARM9 was proposed. The scheme takes S3C2440 as core transplant LINUX operating system,expands GPRS module which has TCP/IP in it,adopts GPRS network and Internet as data transmission channel, and realizes the remote wireless data transmission from gateway node to monitoring center; the hardware structure and the software flowchart of gateway node and server presented. The paper lays special stress on data wireless transmission process, and compares the reliability of the two kinds of wireless transmission protocols TCP and UDP. Experiments show that the wireless data transmission scheme of GPRS module and PC which adopts fixed PI address under TCP transfer protocol is correct and reasonable, thus suitable for remote wireless data transmission system.关键词
