|
Abstract:
在分析EtherCAT通信协议的基础上，设计了一种基于EtherCAT高速数据总线的烟雾报警系统。EtherCAT从站使用FPGA芯片代替国外专用控制芯片实现EtherCAT协议飞读飞写功能，EtherCAT主站将每个从站报警信息实时上报显示。实验结果表明采用EtherCAT总线技术组网避免了基于无极性二线制数据总线的烟雾检测系统难以接入工业物联网的问题，具有成本低、性能可靠等特点。
Based on the analysis of EtherCAT communication protocol, a smoke alarm system based on Ether-CAT high-speed data bus is designed. The EtherCAT slave station uses the FPGA chip instead of the foreign special control chip to realize “on the fly” function of the EtherCAT protocol. The EtherCAT master station will report and display the alarm information of each slave station in real time. The experimental results show that the networking technology of EtherCAT bus avoids the problem that it is difficult for smoke detection system based on non-polar two-wire data bus to access to the industrial Internet of Things. It has the characteristics of low cost and reliable performance.
