Multi-bus network communication architecture

Abstract

The invention relates to a multi-bus network communication architecture. The architecture includes an Ethernet router node, a master station node and slave station nodes. The Ethernet router node is in bridge connection with a data management center and the master station node, the master station node is connected with the slave station nodes through an M-LVDS bus, the slave station nodes communicate with terminal devices, and a network structure formed by cascading the data management center, the Ethernet router node, the master station node, the slave station nodes and the terminal devices is achieved. According to the multi-bus network communication architecture, the communication bandwidth utilization efficiency of a bus communication link can be improved; the network deployment mode can be optimized by configuring the number of the nodes and the node connection relationship, and the access capability can be provided for different types of terminal devices by configuring the slavestation nodes, so that the limitation of the terminal devices in the aspects of access mode, number, bus type and the like can be avoided, flexible network scale expansion is realized, and the multi-bus network communication architecture is suitable for more application environments.

Description

technical field [0001] The present application relates to the technical field of bus network communication, and in particular, to a multi-bus network communication architecture. Background technique [0002] With the increase in the number and types of devices in electronic communication systems, in order to meet the real-time and reliable data transmission requirements between devices, more and more electronic communication systems use bus communication technology to achieve the optimization of each device in the system. communication control. With the development of the data types of devices and the transmission protocol format between devices, the types of buses used by the devices also show a diversified development, such as RS485 bus, which is widely used in industry, CAN bus, which is widely used in automobiles, and high-speed communication applications. LVDS bus, etc. [0003] Due to the differences in the communication methods between different types of buses, when...

AI Technical Summary

Problems solved by technology

This communication method is limited by the bus type and bus driving capability, the number of wiring between devices is large, and the utilization efficiency of bus communication bandwidth is not high.

In addition, when the type or number of access devices changes, the system using the above-mentioned communication methods needs to replace or upgrade the devices accordingly, and adjust the wiring and the number of access points accordingly, which limits the flexibility of the system and makes it difficult to adapt to complex and diverse various application environments
