Abstract: | For the defects of cable fielbus network and the complexity of communication interface between the nodes among the heterogeneous network, a method of amalgamation between fieldbus and wireless ethernet under VxWorks is provided. Using EtherHook, the data acquisition is independent of TCP/IP protocol, the transition equipment is simplified, and the real-time quality of information acquisition is improved;the unified and scalable communication interface of application layer and the independency of application maintenance, upgrades as well as extension of system. Solutions are system,the efficiency of software development and the reusability of the other system. and equipment is convenient for development, universal,and improve the real-time quality of code, and the method can be easily generalized to |
