智能照明系统是自动化技术在照明控制领域的应用推广。基于CAN总线的智能照明控制系统已经逐步在市场推广,而针对CAN通信网络中低优先级数据传输延迟较大、存在实时性和确定性较差的问题,提出了基于时间触发的TTCAN协议,给出了由主节点和多个从节点构成的TTCAN网络系统硬件结构,介绍了一种优化的均匀调度算法的设计和应用。试验结果表明,与标准的CAN网络相比,TTCAN网络照明控制系统提高了总线利用率,并在一定程度上提高了系统的实时性。

The intelligent light system is the applicable promotion of automation technology in lighting control field. The intelligent lighting control system based on CAN bus has been gradually promoted in the market, while there are some disadvantages in CAN communication network, e. g. , low priority data latency, poor real time performance and deterministic, etc. Aiming at this situation, the TTCAN protocol based on time triggering is proposed, and the hardware structure of TTCAN network system which is composed of main node and multiple slave nodes is given. The design and application of the optimized uniform scheduling algorithm are introduced, comparing with standard CAN network, the TTCAN network lighting control system enhances the utilization of bus and improves the real time performance of system in certain extent.
