Design and Implementation of M Bus Control System Based on the VxWorks System

Proposes a new software designing idea and method of implementation for M bus control system based on VxWorks embedded real time systems. In order to realize the function of controlling the device, two real time tasks are set. The one gathers the command and the data collected by sensor, and set the priority; the other runs the command and feeds back the result to the device that needs the result. They communicate by a command buffer link between them. The method used in this paper is simple and highly efficient and can be used in other kinds of control systems related with the M bus system.
