Abstract

The invention relates to a communication method of a high-speed industrial communication system. The communication system comprises a control node and a terminal node, the control node manages a communication system, the terminal node is in communication connection with the control node, the method comprises the steps that the control node is used for sending a control message to a first terminalnode so as to allocate communication resources to the terminal node, and the communication resources comprise time slice resources, frequency band resources and intra-network address resources; and the data message is sent by using the terminal node according to the communication resource allocated by the terminal node. The high-speed industrial communication system is mainly used for solving theproblems that an industrial field traditional bus is low in bandwidth, cannot bear real-time and non-real-time at the same time and is complex in network structure. The high-speed industrial communication system can support IPV6 address communication, time-triggered industrial control communication, TSN, white list, deep detection, data encryption and other security mechanisms.

Description

technical field [0001] This application belongs to the field of communication, and in particular relates to a high-speed industrial communication system and communication method Background technique [0002] Existing industrial control communication systems usually adopt a bus or ring bus topology. The main feature is that a pair of twisted pairs can connect multiple sensors and actuators. This network structure is convenient and simple to install. However, due to the bus connection between the nodes in this topology, the impedance of the nodes is not easy to match completely, and echo multipath will be introduced in the communication, which will have a serious impact on high-speed data communication. The existing on-site industrial control bus represented by CAN bus adopts bus topology and directly uses baseband signals for data transmission. Eliminating the influence of echo multipath requires complex equalization technology, which is difficult to implement. Therefore, th...
