Abstract

The invention provides a dual-communication system based on ARCNET and Ethernet. The system comprises a processing module, an Ethernet communication module, at least two ARCNET communication modules, and photoelectric conversion modules which are in electrical connection with the ARCNET communication modules in a one-to-one manner. The processing module comprises a microcontroller, an external extended SDRAM and an external extended Flash memory, wherein the external extended SDRAM and the external extended Flash memory are electrically connected with the microcontroller. Each ARCNET communication module is electrically connected with the microcontroller, and the microcontroller is electrically connected with the Ethernet communication module. The system achieves the mutual communication between the ARCNET network and the Ethernet network.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a dual communication system based on ARCNET and Ethernet. Background technique [0002] ARCNET network is a local area network technology, which uses token bus (token-bus) to manage the nodes on the local area network and the data link between nodes, with time determinism, flexible data transmission mode, high reliability and support for multiple ARCNET network has been widely used in the field of rail traffic control. [0003] The existing train control system based on the ARCNET network is mainly composed of bus equipment inside the vehicle, vehicle nodes (including network cards and computers), and transmission media, and has completed functions such as train control, information collection and display, data transmission and processing. With the development of science and technology, Ethernet has become the next generation train network communication standard. ...
