The gateway device is characterized in that the Zigbee wireless module is in charge of receiving various sensing data and sending various automatic control commands to an instrument and a meter; the central processing module is in charge of EtherCAT drive, data and control interaction processing with the Zigbee wireless module and the EtherCAT module and the realization of an application program; and the EtherCAT module realizes a slave station function and realizes the interaction processing of main station data and control in a distributing type control unit. The invention can realize the combination of a real-time wired high-speed Ethernet EtherCAT and Zigbee wireless sensing technology, bring great convenience to the arrangement and planning of a transmission channel and reduce puzzle and cost brought by great cable construction.

Description

technical field [0001] The invention relates to a device and a method in the field of network technology, in particular to a gateway device between EtherCat industrial Ethernet and wireless Zigbee and a protocol conversion method thereof, belonging to the field of communication technology. Background technique [0002] Real-time industrial Ethernet EtherCAT technology is a general ultra-high-speed Ethernet field bus technology developed in recent years, which is used to replace PROFIBUS, CANopen, and MODBUS industrial bus technologies. The so-called industrial field bus is to make data acquisition devices, that is, field instruments and control units, interconnected through the bus to realize data acquisition, analysis and automatic control. [0003] The EtherCAT protocol is an extended Ethernet system based on the IEEE802.3 standard, which enables predictable timing and high-precision synchronization in data transmission. The traditional Ethernet media access control metho...

AI Technical Summary

Problems solved by technology

The traditional Ethernet media access control method, that is, the carrier sense multiple access mechanism with collision detection is a non-deterministic media access control method that cannot meet the real-time requirements of industrial sites, so EtherCAT can replace the original Ethernet The network-star topology can easily establish a linear topology. As the master station, the standard Ethernet controller can meet the requirements, and no specific hardware equipment is required.
