Abstract

The invention relates to a one-to-many bus gateway device based on SRIO, comprising a gateway module, which is used for carrying out protocol conversion and bus data transceiving. The gateway module comprises an SRIO-CAN gateway module, an SRIO ethernet gateway module, an SRIO-ARINC gateway module and an SRIO USB gateway module; CAN bus equipment is connected to an input end of the SRIO-CAN gateway module; ethernet equipment and USB equipment are respectively connected to an output ends of the SRIO ethernet gateway module and the SRIO-USB gateway module. The CAN bus equipment inputting CAN formatted data to the SRIO-CAN gateway module, a transceiver circuit of the SRIO-CAN gateway module storing the input CAN formatted data, converting the data into an SRIO format, and sending the data toa switching module; the switching module transmitting the SRIO formatted data to all connected gateway modules after receives the data from the CAN-SRIO direction gateway; the SRIO ethernet gateway module converting the SRIO format into an ethernet format after receives the data from the switching module, and sending to an ethernet device through the output end of the transceiver circuit.

Description

technical field [0001] The invention relates to a gateway technology, in particular to an SRIO-based one-to-many bus gateway device. 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 device for solving the above-mentioned problems in the prior art. [...
