[0035] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0037] The solution provided by the embodiment of the present invention can be applied to any application scenario where a traditional communication terminal needs to access a time-sensitive network.

[0038] The embodiment of the present invention provides a possible implementation method, such as Figure 1 As shown, a time-sensitive network communication device is provided, including a basic chip, a first communication module, a second communication module and a data cache module arranged on the basic chip, wherein the first communication module and the second communication module are respectively connected to the data cache module;

[0039] The first communication module is used to connect to a PCIE bus, the second communication module is used to connect to a time-sensitive network, and the data cache module is used to cache data received through the first communication module and the second communication module.

[0040] Optionally, the basic chip may be an FPGA chip. The basic circuits involved may be found in Figure 2 As shown, in this solution, the basic chip is used as the core processing platform.

[0041] The time-sensitive network communication device provided by this solution can be a standard PCIE plug-in card device, supporting access by various traditional communication terminals with a PCIE bus.

[0042] Among them, see Figure 1 The first communication module may also be referred to as a PCIE protocol implementation and communication module, and the second communication module may also be referred to as a TSN protocol implementation and communication module. The first communication module implements communication with the outside based on the PCIE protocol, and the second communication module implements communication with the outside based on the TSN protocol.

[0043] Optionally, the data cache module may be a BRAM inside the FPGA. The data cached in the data cache module may be first data received through the first communication module and / or second data received through the second communication module.

[0044] Based on the configuration of the first communication module and the second communication module, the traditional communication terminal can send and receive data through the first communication module, and can also send and receive data through the second communication module.

[0045] See also Figure 3 The data cached in the data cache module may specifically include monitoring data, business queues, and business flows. Among them, monitoring data refers to data obtained by monitoring the monitored object through monitoring equipment, and the monitoring equipment can be used as a traditional communication terminal to transmit monitoring data to the data cache module. Business queues and business flows both refer to data related to the business. The business queue can store tasks that need to be executed, and the business flow is the data corresponding to the execution of each task.

[0046] based on Figure 3 It can be seen that the data received by the time-sensitive network communication device may also include messages. Different processing can be performed on the various different data received. For example, the message is processed by the general message processing module, and the processed message is delayed and shaped by the sending service flow delay shaping module, and then the shaped data is sent to PHY through MAC_TX. The monitoring data and the service queue can also be delayed and shaped by the sending service flow delay shaping module, and then sent to PHY through MAC_TX. The time-sensitive network communication device may also include a time synchronization module, configuration registers and DMA (Direct Memory Access). DMA allows hardware devices of different speeds to communicate without relying on a large interrupt load of the CPU. For the specific processing process, please refer to Figure 5 The data processing flow shown in Figure 5 In the figure, queues 0 to 7 represent service queues. The DMA module applies to the host for read and write operations, performs corresponding queue data read operations based on the captured arbitration results, and puts the read queue data into the corresponding packet cache. The sending arbitrator opens the 8 upstream packet cache channels according to the configuration and clock, obtains the packet cache data in the channel and sends it to the ring scheduler, and then sends the data out through the sending MAC.

[0047] In the solution of the present application, the PCIE bus exchanges data between the host and the device through DMA. Figure 4In the TSN protocol, dual-channel network transmission interfaces are implemented. In each network interface, the data packet is time-tagged at the interface where the data is sent to achieve 802.1AS time synchronization. 802.1AS is a general precision time protocol in the TSN protocol cluster. In order to implement the 802.1QAV and 802.1Qbv functions in the data transmission process, the transmission data is shaped and scheduled. 802.1QAV and 802.1Qbv are traffic scheduling protocols in the TSN protocol cluster. During the data reception process, the data flow is monitored and managed to implement 802.1Qci. 802.1Qci is a protocol for traffic supervision in the TSN protocol cluster. The 802.1CB module manages and configures the input and output processes of the two networks, encodes in the output process, and copies the same data to output from both channels at the same time. Decoding is performed in the input process, and the two data channels are checked, leaving the correct data on one channel and discarding the data on the other channel (regardless of whether the data is correct). 802.1CB is a redundancy-related protocol in the TSN protocol cluster.

[0048] Optionally, the basic chip also includes a PCIE bus interface and a TSN network hardware interface, the first communication module is connected to the PCIE bus through the PCIE bus interface, and the second communication module is connected to the time-sensitive network through the TSN network hardware interface.

[0049] Optionally, the TSN network hardware interface is a dual-channel Gigabit redundant optical port, which includes two optical ports, each of which is used to provide an interface for connection between the second communication module and the time sensitive network. Redundant communication is achieved through the dual-channel optical port.

[0050] Optionally, for each optical port, the optical port is also used to store backup data through a hardware redundant channel.

[0051] As an example, see Figure 1 The two optical ports shown in FIG. 1 can store backup data in the hardware redundant channel through optical signal 1 and optical signal 2. The backup data can be at least one of the above-mentioned received data.

[0052] In the present application, the two optical ports maintain real-time data backup through hardware redundant channels, and can retain the data that needs to be backed up in the communication line in real time, providing dual backup of hardware lines and software traffic, which can effectively improve the functional safety level of communication.

[0053] Optionally, a configuration management module is also provided on the basic chip, and the configuration management module is used to manage the network corresponding to the PCIE bus and the time-sensitive network.

[0054] Optionally, the time-sensitive network communication device also includes a power module, which includes a DC-DC converter with a wide voltage input, for converting a first voltage into a second voltage and providing the second voltage to the time-sensitive network communication device, wherein the first voltage is higher than the second voltage.

[0055] Optionally, the first voltage may be +12V, and the second voltage may be at least one of +3.3V, +1.8V, +1.2V, and +1.0V.

[0056] Based on Figure 1 The present invention also provides a communication method based on the same principle as the method shown in Figure 6 , the scheme may be executed by a time-sensitive network communication device, and the method may include the following steps:

[0057] Step S10, receiving first data of a first device, where the first device is a device accessed through a first communication module in a time-sensitive network communication device;

[0058] Step S20, receiving second data of a second device, where the second device is a device accessed through a second communication module in the time-sensitive network communication device;

[0059] Step S30: caching the first data and / or the second data by means of a data caching module in the time-sensitive network communication device.

[0060] Wherein, both the first device and the second device can be traditional communication terminals.

[0061] It should be noted that the execution order of the above steps S10 and S20 is not limited.

[0062] The solution of the present invention has the following advantages:

[0063] Based on TSN network communication technology, PCIE bus technology and FPGA technology system, traditional communication terminals can access the TSN communication network through the PCIE bus, and have the time synchronization, low scheduling delay, high reliability and flexible resource management functions unique to the TSN network.
