Abstract

The invention relates to an SRIO-based one-to-many bus gateway conversion method. The method comprises the following steps: connecting a CAN bus device of a user an input end of an SRIO-CAN gateway module, and connecting an Ethernet device and a USB device of the user to output ends of an SRIO-Ethernet gateway module and an SRIO-USB gateway module; establishing, by the SRIO-CAN gateway module, theSRIO-Ethernet gateway module and the SRIO-USB gateway module, SRIO connections with a switching module; starting the CAN bus device of the user to input CAN format data to the SRIO-CAN gateway module, storing, by the SRIO-CAN gateway module, the received CAN format data in a CPU, and converting, by the CPU, the data into an SRIO format, and sending the data to the switching module; after receiving the data from a CAN-SRIO direction gateway, forwarding, by an SRIO switching module, the data in the SRIO format to all gateway modules that have established the connections through a VPX bottom plate in an objectless manner; and after receiving the data from the switching module, forwarding, by the SRIO-Ethernet gateway module, the data to the CPU, and converting, by the CPU, the SRIO format into an Ethernet format, and sending the data to the Ethernet device of the user through the output end of a transceiver circuit.

Description

technical field [0001] The invention relates to a gateway technology, in particular to an SRIO-based one-to-many bus gateway conversion method. Background technique [0002] With the development of computer network and bus technology, the demand for protocol conversion between different buses is becoming more and more vigorous. In a certain practical application environment, it is necessary to convert CAN bus data into Ethernet, ARINC and USB bus data. The traditional approach is for users to purchase three gateway devices: CAN-to-Ethernet, CAN-to-ARINC, and CAN-to-USB. These three gateway devices come from different suppliers and require a long time for procurement and adaptation. At the same time, three gateway devices require three CAN cable devices, which increases the cost of materials. Contents of the invention [0003] The object of the present invention is to provide an SRIO-based one-to-many bus gateway conversion method, which is used to solve the above-mention...
