Embodiment Construction

[0054] In order to solve the problem of low communication efficiency of industrial Ethernet in the prior art, an embodiment of the present invention provides a data processing method in industrial Ethernet. There are all slave stations that communicate with each other, and then the master station determines the data transmission path between itself and each slave station, and finally sends the business data packets of each slave station continuously according to the transmission order of the transmission path from far to near data pack. Therefore, in the embodiment of the present invention, after the master station determines all the slave stations that communicate with the master station in the Ethernet, the master station will continuously deliver the service data packets of all slave stations, so that the master station will The efficiency of sending business data packets is improved, which also improves the communication efficiency of industrial Ethernet.

Abstract

The invention provides a method and a device for data transmission in an industrial Ethernet. The method comprises the following steps: a master station determines all slave stations communicating with the master station in a current industrial Ethernet; the master station determines a data transmission path between the master station and each slave station; and the master station continuously sends the service data packets of the slave stations according to the service data packet sending sequence from far to near in transmission path. The master station continuously sends the service data packets of all the slave stations after determining the slave stations communicating with the master station in the Ethernet, so that the efficiency of service data packet sending by the master station is increased, and the communication efficiency of the industrial Ethernet is increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and device in industrial Ethernet. Background technique [0002] At present, at least one master station and several slave stations are included in the industrial Ethernet network, and each slave station contains at least two network ports. Such as figure 1 shown), in the figure 1 The master station and N slave stations form a chain network, and then the master station sends service data packets to each slave station through the link. [0003] However, in the prior art, when the master station sends business data packets to the slave station, the master station will be affected by the slave station’s business processing process, for example, the slave station sends feedback data packets to the master station or the slave station sends data packets to other slave stations When the station forwards the service data packet, the master station wil...
