Abstract

The invention discloses an EtherCAT Ethernet gateway and a working method thereof. The gateway comprises an EtherCAT bus protocol controller, an EtherCAT bus transceiver, a Nios II central controller, a Powerlink bus protocol controller, and a Powerlink bus transceiver, wherein the Nios II central controller is respectively connected to the EtherCAT bus protocol controller and the Powerlink bus protocol controller in two directions, and the Powerlink bus protocol controller is connected to the Powerlink bus transceiver in two directions. Through the Nios II central controller, the invention realizes the data exchange between the EtherCAT bus protocol controller and the Powerlink bus protocol controller, which solves the communication problem between the EtherCAT and Powerlink in a train communication network.

Description

technical field [0001] The invention relates to a data conversion device between different network buses, in particular to a NiosII-based EtherCAT Ethernet gateway and a working method thereof. Background technique [0002] With the increasingly widespread application of industrial Ethernet, the Ethernet used for office and information automation begins to extend downwards, and is directly applied to field automation control. [0003] In the field of locomotive control network, with the improvement of train automation and comfort, the amount of on-board data including train operation control, passenger information system, and multimedia has increased sharply, and traditional CAN, DeviceNet, PROFIBUS, WorldFIP and other field buses) have gradually shown disadvantages, such as Low transmission rate, poor versatility, etc. At present, foreign transportation equipment manufacturers such as Bombardier have successfully applied Ethernet to the EMU train network control system. I...
