Collaborative Design of Heterogeneous Data Integration Communication Gateway Based on the Embedded Platform

An embedded gateway serving for the communication between Ethernet and the heterogeneous multilayer interfaces is put forward in this paper. Based on the analysis of the common application requirements in multi-industry, the functions of this system are planned. Collaborative design is adopted in the routing gateway. The models of hardware and software are presented in detail. In the scheme of hardware, S3C44b0X based on ARM7TDMI is used as the core of the gateway, the primary/backup ports based on ENC28J60 are introduced to improve the reliability of communication, and the TL16C554 is selected to extend serial ports. muC/OS-II has been transplanted in the embedded platform, so the subsequent development and the maintainability have been advanced. Routing protocol integrating I/O data, frame data and package data from the heterogeneous multilayer interfaces is designed and realized. Multi-application scene equipments are implemented by the routing communication gateway.
