【摘要】 CANopen协议是基于CAN总线的应用层协议,适用于分布式控制系统。网络的引入使系统具有一些优势,同时也导致了系统变量的抖动问题,将影响系统的性能,采用优化算法能够减小系统的抖动。根据CANopen的传输特性,分析CANopen实时通信问题,采用了遗传算法来实现同步报文调度的优化。通过CANoe软件对多传感器网络系统进行仿真实验。结果表明,该调度方法有效地减少了网络中的抖动问题,改善了系统的性能。更多还原

【Abstract】 As a kind of CAN-based application layers, the CANopen protocol has been widely adopted for distributed control system. While the introduction of network gives the system some advantages, the jitter problem of system variables is induced and degrades the performance of systems. The optimal algorithm can be used to reduce the jitter of system variables. According to the CANopen transmission features, the real-time communication problems in CANopen are analyzed. The genetic algorithm is used to optimize the synchronous message scheduling. A multiple sensor network is simulated using the CANoe software. The result shows that the jitter problem in the network can be effectively reduced and the performance of the system can be improved.更多还原
