Payload: Payload, this article refers to the content in the FC frame except the locator of the frame header and tail, CRC check, and frame header.

In addition, the main application scenario of the embodiment of the present invention is FC, and FC is mainly applied to an avionics communication system, and is applicable to an avionics environment. The protocol that supports the FC operation of the avionics communication system is called the FC protocol. In the FC protocol, there will be different terminals and switches at the same time to serve the normal operation of the avionics communication system.

It should be explained that, in different FC protocols, terminal types are different, and interaction modes between terminals are also different. For example, in the FC-AE-1553 protocol, terminals are divided into network controllers (NC) and network terminals (NT), and the interaction mode between the two is command-response; in the FC-AE-ASM protocol, each terminal is the same relationship, but different FC protocols generally rely on the switching network shown in Figure 1.

Figure 1 is a common FC switching network. In the FC switching network, when there is a need for communication between terminals and between terminals and switches in the switching network, they all need to rely on the switching network.

It should be explained that, in the embodiment of the present invention, the automatic maintenance of the connection status of each terminal in the FC switching network link depends on the main switch and the secondary switch. There is only one main switch in the switching network, and the others are sub-switches; the main switch is responsible for maintaining the terminal connection status of the entire network, providing a unified interface for other terminals to query the internal terminal connection status of the switching network, and the sub-switch is only responsible for maintaining its own terminal connection status; When the terminal connection information of the secondary switch changes, the change information needs to be synchronized to the main switch.

In this embodiment of the present invention, the first terminal and the second terminal are taken as examples, and for the convenience of description, the terminal access information request ends of the first terminal and the second terminal are respectively separated, and the access information of the first terminal and the second terminal is described. In addition, the first terminal is connected to the main switch, and the second terminal is connected to the secondary switch. Please refer to Figure 2 for a detailed example diagram.

What needs to be explained in turn is that the terminal access information table specifically refers to the collection of terminal information that is connected to the FC switching network and can communicate normally. Each terminal information includes terminal name, terminal address, connected switch identifier, etc., which can be added according to actual needs. other information. In the embodiment of the present invention, the terminal access information table includes network-wide and local points, wherein the network-wide terminal access information table is maintained by the master switch, and the local terminal access information table is maintained by the sub-switch.

Furthermore, when the terminal starts up and accesses the switching network for the first time or after the connection is disconnected, it needs to assign an address to the terminal. Taking the first terminal as an example, the detailed execution process includes:

transmitting the login protocol of the first terminal to the main switch;

Generate an assigned address of the first terminal in the main switch, fill the assigned address into the login response frame and send it back to the first terminal, and simultaneously obtain a terminal name including the first terminal, The terminal address and the terminal information identified by the connected switch are stored in the network-wide terminal access information table of the main switch.

In addition, in another embodiment of the present invention, when the first terminal voluntarily withdraws from the switching network, it also needs to perform data interaction with the main switch. The detailed execution process includes:

Based on the communication protocol for exiting the switching network, a request for exiting the switching network communication is generated at the first terminal and sent to the main switch;

When the main switch receives the request to exit the switching network communication, delete the terminal information of the first terminal in the terminal access information table of the whole network of the main switch;

When the terminal information of the first terminal is successfully deleted, the exit response frame is generated and fed back to the first terminal to complete the process of the first terminal actively exiting the switching network.

Similarly, as shown in Figure 2, the second terminal corresponds to the sub-exchange. When the second terminal logs in or exits the switching network, the execution process is similar to that of the first terminal. The main difference is that the local terminal of the sub-exchange can directly access information. Write or delete the second terminal information in the table. And the second terminal information needs to use the secondary switch to connect to the main switch, and then insert or delete the second terminal information in the network-wide terminal access information table of the main switch.

Referring to FIG. 3 , it is a schematic flowchart of a general method for obtaining terminal connection status based on FC switching network provided by an embodiment of the present invention. In this embodiment, taking the first terminal as an example, the general method for obtaining the terminal connection status based on the FC switching network includes:

S1. Receive a connection request frame from a terminal, and send the connection request frame to a pre-built master switch;

It should be explained that there is only one main switch in the switching network, and the others are sub-switches. The main switch is responsible for maintaining the terminal connection status of the entire network and providing a unified interface for other terminals to query the internal terminal connection status of the switching network. The sub-switch is only responsible for maintaining its own Terminal connection status. When the terminal connection information of the secondary switch changes, the change information needs to be synchronized to the main switch.

In the embodiment of the present invention, when the terminal is about to enter the switching network, it needs to directly perform communication protocol conversion with the switch, and the terminal is not allowed to enter the switching network until the communication protocol conversion requirements are met.

It should be explained that both the terminal and the main switch or the secondary switch include LS_REQ: Link State Request (Network Node Link State Request Protocol, referred to as Link State Request Protocol) and LS_ACK: Link State Acknowledge (Network Node Link State Acknowledgment Protocol, referred to as Link State Request Protocol) response protocol).

Specifically, referring to FIG. 4 , the generating request connection frame according to the connection status request protocol includes:

S11. Generate a general frame according to the structural information of the pre-built general frame and the FC network standard;

S12. Change the frame type of the general frame to obtain a connection request frame whose information needs to be completed;

S13. Obtain the ID of the main switch and the ID of the terminal;

S14. Combine the ID of the master switch and the ID of the terminal into the connection request frame whose information needs to be completed to obtain the connection request frame.

It should be explained that the general frame of the present invention is a protocol that supports the FC operation of the avionics communication system, that is, the general frame format of the FC protocol. One of the general frame formats is shown in Figure 5, which mainly includes SOF, CRC, EOF, Common frame header and Data_Field. Among them, SOF, CRC, EOF, and Data_Field are common technical identifiers in the communication field, and will not be repeated here.

Combined with what is shown in Figure 5, continue to refine the structure of the general frame header, please refer to Figure 6. As shown in Figure 6, the general frame header includes R_CTL, D_ID, S_ID, Payload, etc., where D_ID is the ID of the device receiving the FC frame, S_ID is the ID of the device sending the FC frame, R_CTL is set to 0x22, and Payload is referred to as the load. In the embodiment of the present invention, it refers to other information content except SOF, CRC and other content.

In the embodiment of the present invention, changing the frame type of the general frame to obtain the request connection frame whose information needs to be completed includes:

Obtain a frame type value table, and look up the frame type value corresponding to the request connection frame in the frame type value table;

Extracting the frame number of the connection request frame sent by the terminal this time, filling the frame number and the value of the frame type into the general frame, and obtaining the connection request frame whose information is to be completed.

In the embodiment of the present invention, the frame type of the connection request frame is 0xA7.

It should be explained that the frame number of the request connection frame refers to the Req_Num field in the payload format of the LS_REQ frame, which is gradually increased by the number of times. For example, when the terminal sends a connection request for the first time, the corresponding frame number is 0, and the second time When sending a connection request, the corresponding frame number is 1.

In detail, the payload format of the connection request frame is shown in FIG. 7 . The payload format of the LS_REQ frame has a total of 8 bytes. Req_Num is the serial number of the LS_REQ frame sent by the terminal, and is used to identify each LS_REQ frame.

In the embodiment of the present invention, the sending the request connection frame to the pre-built master switch includes:

judging whether the terminal is directly connected to the main switch;

If the terminal is directly connected to the main switch, sending the connection request frame to the main switch;

If the terminal is not directly connected to the main switch, the connection request frame is forwarded several times by the pre-built secondary switch to reach the main switch.

In detail, when the connection request frame needs to be forwarded by the sub-switch, the sub-switch identifies whether it is the first time to receive the frame according to the S_ID and Req_Num, and if so, forwards the frame from the cascade port, otherwise directly throw away. The connection request frame is forwarded several times by the secondary switch to the main switch.

S2. Judging whether the connection request frame is sent to the main switch for the first time;

In the embodiment of the present invention, the judging whether the connection request frame is sent to the main switch for the first time includes:

extracting the frame sequence number and the ID of the terminal from the connection request frame;

According to whether the main switch has the same historical frame number and ID as the frame number and the ID of the terminal, it is judged whether the connection request frame is sent to the main switch for the first time.

Further, the generation process of the request response frame is similar to the request connection frame, the main difference is that the frame type value corresponding to the request response frame in the frame type value table, for example, the frame type of the above request connection frame The value is 0xA7, and the frame type of the request response frame is 0xA8.

In detail, the payload format of the request response frame is shown in FIG. 8 . The length of the request response frame depends on the number of pieces containing terminal information. Each piece of terminal connection information in the request response frame includes: SW_Num (identification of the switch to which the terminal is connected), Node_ID (address of the terminal) and Node_Name (name of the terminal).

In the embodiment of the present invention, the judging method for judging whether the connection request frame is sent to the sub-switch for the first time is the same as the judging method for judging whether the connection request frame is sent to the main switch for the first time. The historical frame numbers and IDs whose frame numbers are the same as the ID of the terminal will not be repeated here.

If the connection request frame is sent to the main switch for the first time, execute S3, extract terminal information in the main switch, and obtain a request response frame according to the terminal information encapsulation;

In the embodiment of the present invention, the terminal information can be obtained from the network-wide terminal access information table of the host switch, and the terminal information includes terminal name, terminal address, connected switch identifier, etc. Other information can be added according to actual needs information.

In the embodiment of the present invention, the method for generating terminal information includes:

transmitting the login protocol of the terminal to a switch connected to the terminal;

Generate the distribution address of the terminal in the switch, fill the distribution address into a pre-built login response frame and send it back to the terminal, and obtain the terminal name, terminal address, and connected switch of the terminal at the same time The identified terminal information is stored in the network-wide terminal access information table of the master switch to obtain the terminal information.

Since the specific implementation process of writing the terminal information into the local terminal access information table is similar to the above, it will not be repeated here.

In the embodiment of the present invention, said encapsulating and obtaining the request response frame according to the terminal information includes:

generating an original response frame according to the structural information of the general frame and the FC network standard;

changing the frame type of the original response frame to obtain a request response frame whose information needs to be improved;

Encapsulating the terminal information into the request response frame whose information is to be completed, to obtain the request response frame.

It should be explained that the embodiment of the present invention encapsulates the terminal information into the Payload in the request response frame.

If the connection request frame is not sent to the master switch for the first time, perform S4 and not respond to the request response frame;

Understandably, since there may be multiple routes between the two switches, the same connection request frame may be forwarded to the main switch through different routes, causing the main switch to repeatedly receive the connection request frame, so , when the connection request frame is not sent to the master switch for the first time, there is no need to respond to the request response frame.

S5. Return the request response frame to the terminal to obtain terminal connection status information.

Specifically, when the request response frame needs to be forwarded by the sub-switch, the sub-switch identifies whether the frame is received for the first time according to the D_ID and Ack_Num, and if so, forwards the frame from the cascade port, otherwise discards it. The request response frame is forwarded several times by the secondary switch to the requesting end. The terminal connection status information includes a collection of terminal information that is connected to the FC switching network and can communicate normally.

Based on the background technology: static configuration and dynamic configuration can effectively complete the terminal access to the FC switching network, but limited by the diversity of FC protocol clusters, there is no general terminal that meets multiple groups of FC protocol clusters. The method of connecting to the FC switching network. In order to solve this problem, the embodiment of the present invention divides the switch in the FC switching network into two types: the main switch and the secondary switch. The main switch is responsible for maintaining the terminal connection status of the entire network, and the secondary switch is only responsible for maintaining its own terminal connection. The connection ultimately depends on the control of the main switch to the terminal connection status of the entire interactive network. When the terminal requests the network connection status, by judging whether the request connection frame is sent to the main switch for the first time, the connection request frame is sent to the main switch for the first time. Executing different response strategies, if the connection request frame sent by the terminal is sent to the main switch for the first time, then obtain the terminal information corresponding to the terminal, and obtain the request response frame according to the terminal information encapsulation, If the connection request frame is not sent to the main switch for the first time, no response is made to the request response frame, so as to avoid the possibility of repeatedly receiving the request response frame. Therefore, the present invention makes the two access strategies an organic interface, which can maximize the realization of terminal access failures caused by different protocols. Therefore, the general acquisition method, device, electronic equipment and computer-readable storage medium based on the terminal connection state of the FC switching network proposed by the present invention can solve the problem that the terminal cannot be universally connected to the FC switching network due to the diversity of the FC protocol cluster .

As shown in FIG. 9 , it is a functional block diagram of a device for universally acquiring terminal connection status based on an FC switching network provided by an embodiment of the present invention.
