[0114] see figure 2 , the embodiment of the present invention provides a kind of specific implementation of the data sending and receiving method based on train ethernet card, and this method comprises:
[0115] Step 100: configure the programmable SoC in the train Ethernet card through the backplane bus interface;
[0116] It can be understood that the programmable SoC integrates the processor, FPGA and memory (or off-chip storage control interface) on a single chip to form a programmable system-on-chip. The programmable system has a flexible design method, which can be cut, expanded, and upgraded, and has the function of software and hardware programmable in the system. In the programmable device, there is also a small-capacity high-speed RAM resource.
[0117] Step 200: Based on the configured programmable SoC, based on the configured programmable SoC, send and receive PTP message information, and perform clock synchronization;
[0118] The PTP message information follo...

The invention provides a train Ethernet card based on a TSN and a data transceiving method, the train Ethernet card based on the TSN comprises a programmable SoC, an Ethernet communication interface,a backboard bus interface and a peripheral circuit, and the programmable SoC is connected with the backboard bus interface through a backboard bus; the programmable SoC is respectively connected withthe Ethernet communication interface and the peripheral circuit; and the programmable SoC is used for being responsible for TRDP protocol Ethernet communication and a TSN network function. According to the invention, the problems of uncertainty of Ethernet transmission time delay and the like of the traditional train Ethernet communication are solved by utilizing the technical characteristics of the TSN. The Ethernet interface can be used as an Ethernet interface of key equipment of a train, and is accessed to the Ethernet of the whole train to finish interaction of control information and state information with other equipment.
Description
technical field [0001] The invention relates to the technical field of rail vehicle communication, in particular to a TSN-based train Ethernet card and a data sending and receiving method. Background technique [0002] In recent years, because the transmission rate of the Ethernet-based vehicle network control system has been greatly improved compared with the traditional fieldbus, it can well cope with the diverse and high-bandwidth transmission requirements in the future, and the network topology is flexible and the system has good scalability. At home and abroad, research on train Ethernet has gradually become a hot spot. For example, in 2008, Canada's Bombardier first equipped regional trains in Germany and the Netherlands with an on-board Ethernet system. In 2017, Siemens of Germany equipped the ICE 4 high-speed train with the Sibas PN control system based on PROFINET real-time industrial Ethernet. Simon Corporation of the United States has developed a real-time Ethern...
