Software Design for CNC System Based on Event-Driven Framework

To satisfy the multitask parallelism, priority preemption and loose coupling among modules of CNC system, a RTOS platform of CNC system based on event-driven framework was proposed and each module task was researched. In this paper, the characteristics of structures are that the framework provides methods for module construction, task scheduling, information exchange, system integration, etc. Firstly, the services provided by the framework were elaborated. Then, based on the actual application, this paper expounded the method of using framework to the design of the system software. In this way, the CN C system has a good openness and high development efficiency.
