[Abstract]:With the rapid development of network technology and the rapid spread of new fieldbus technology, which is typical of industrial Ethernet, it has laid a foundation for the production of automatic control network. Industrial Ethernet bus based on EtherCAT has become the trend of industrial Ethernet technology development nowadays and in the future because of its flexible network topology, simple system configuration, high speed and high efficiency of data transmission and low cost. The research and development of the interface technology based on EtherCAT, bus is of great practical significance to improve the level of industrial automation in China. In this paper, based on EtherCAT industrial Ethernet field control system as the research background, focusing on the EtherCAT bus protocol, master station control system architecture, hardware and software design and system testing methods and other aspects. In this paper, the research status and development of industrial Ethernet are introduced, the working principle of industrial Ethernet and EtherCAT, bus is expounded, and the protocol of EtherCAT, bus is deeply analyzed. Then, the overall structure of the system is analyzed in detail, and the hardware design scheme based on EtherCAT master station system is put forward by combining EtherCAT industrial Ethernet with ARM embedded technology. The key technology and design of each function unit of the master station circuit schematic diagram are discussed in detail, and the PCB routing design of the master station system is finally completed. In the process of hardware design, the design of EMC is added, and the stability of system performance is improved. Then, the architecture of real-time control system based on Linux operating system is proposed, and the software design of EtherCAT master station system is described in detail. The development platform and system structure of the software system are introduced. The realization mechanism of communication between EtherCAT master station and slave station is analyzed. The software design of the system is completed by developing the application layer module. Finally, the test platform is built based on the completion of hardware and software. The slave station system is composed of the EtherCAT, bus coupler BK1120 and I / O module (KL2809,KL1809) produced by BECKHOFF, and the main station module of EtherCAT designed in this paper. And test and result analysis. The final experimental results show that the EtherCAT master station hardware and software design meets the design requirements.
