Gprs-based Embedded Systems Intelligent Protocol Processor

In the previous large-scale Supervision systems, there are such problems that the data acquisition appliances are various, and the protocols are different in dissimilar equipments while the transmission mode is single. These problems do not only delay the access speed between the control center and each equipment, but also limit the flexibility and the compatibility of the supervision systems. To solve these problems, an intelligent protocol processor based on GPRS is studied and developed in this paper.Having comprehended Embedded System and Arm microprocessor, this paper emphasis on how to realize some key technical problems of this intelligent protocol processor through GSM network by ARM microprocessor on the embedded Linux platform, such as Wireless Data Transmission by GSM network, multi-protocol normalization, data processing intelligentizing, and so on. The intelligent protocol processor's requirement and function is also realized in this paper, which is important to raise the efficiency of acquisiting collected data by control center, to support the multi-class interfaces and protocols, to simplify the manage tasks of the control center and transmission protocols, to transmit remote radio data, and so on.
