[0045] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] For devices in an SRB system (a system consisting of multiple SRB devices working together to complete a certain function), all devices in the SRB system must have the same software version to ensure consistent operation.

[0047] If the software configured in the device has a program error BUG or the function needs to be updated, all devices in the SRB system need to be upgraded. Then how to upgrade the devices is a technical problem that those skilled in the art urgently need to solve.

[0048] In the related art, software to be upgraded can be placed on a PC (Personal Computer) and then upgraded to the device by means of an upgrade tool software such as TFTP (Trivial File Transfer Protocol).

[0049] One of the upgrade methods is to upgrade the devices in the SRB system one by one.

[0050] As shown in the figure, since the PC generally has only one network port, the port is first used to connect the PC and the device 1, and then the device 1 is upgraded. Figure 1 Then the connection between the PC and the device 1 is disconnected, the PC and the device 2 are connected, the device 2 is upgraded, and the above process is repeated until all the devices are upgraded.

[0051] The disadvantage of this upgrade method is that it cannot upgrade multiple devices at the same time, and each device needs to be upgraded one by one, and the network cable needs to be plugged and unplugged frequently, which is inconvenient to operate and takes a long time to upgrade.

[0052] The other upgrade method is to upgrade all the devices at one time.

[0053] As shown in the figure, the PC can be connected to multiple devices at the same time by means of a switch, and then each device is upgraded. Figure 2 Specifically, the PC and the devices 1, 2, … are connected by means of the switch, and then the devices are upgraded. This method can upgrade multiple devices at the same time, but it needs to use an external device such as a switch, and the upgrade data needs to be sent to each device for upgrade operation. When the number of devices to be upgraded is large, the upgrade data needs to be sent multiple times, and the upgrade process is complicated.

[0054] As can be seen from the above, when upgrading all the devices in the SRB system, either the devices are upgraded one by one, which is inconvenient to operate and takes a long time to upgrade, or an external device is needed and the operation is complicated, and sometimes there is no external device to use, which is inconvenient to upgrade.

[0055] Therefore, in the embodiments of the present application, in order to simplify the upgrade process, only the upgrade data packet needs to be sent to one of the devices in the SRB system, and then the communication mechanism of the SRB system is used to make each device in the SRB system receive the upgrade data packet and complete the upgrade operation, thereby improving the efficiency of device upgrade. Through the present application, all the devices in the system can be upgraded at the same time, and an external device is not needed, which is simple to operate and has high upgrade efficiency.

[0056] Based on the above content, an embodiment of the present invention provides a device upgrade method applied to an SRB system, which is applied to a target device in the SRB system. The target device is any device in the SRB system.

[0057] There is no limit on the number of devices and the connection method in the SRB system. Figure 3 As shown, the SRB system includes four devices, namely device 1, device 2, device 3, and device 4. The four devices are connected in a ring. In addition, the four devices can also adopt other topologies, such as linear topology or star topology.

[0058] For the four devices in the SRB system, one of them needs to be connected to the PC to receive the upgrade data message sent by the PC.

[0059] In actual scenarios, the specific device selected for connection to the PC can be determined based on the actual configuration. For example, a device can be randomly selected, the device with the highest or lowest serial number can be selected, or the device with the lowest operational burden can be connected to the PC. The device connected to the PC connects to the PC through its own Ethernet port. The SRB communication port of this device, such as the SRB service port, is connected to other devices in the SRB system. The SRB communication ports of other devices are also connected to the SRB communication ports of the corresponding device.

[0060] For example, for each device in the SRB system, two SRB communication ports are configured for it, namely port A and port B. Figure 4 As shown, if device 2 is connected to a PC, the Ethernet port of device 2 is connected to the PC, port A of device 2 is connected to port B of device 1, and port B of device 2 is connected to port A of device 3. The connection structure of the remaining ports is as follows. Figure 4 shown.

[0061] Based on the above connection structure, refer to Figure 5 A device upgrade method applied to an SRB system may include:

[0062] S11. Obtain upgrade data message.

[0063] In this embodiment, when upgrading all devices in an SRB system, the software to be upgraded must first be determined. The corresponding upgrade file must then be placed on a PC. The PC then triggers the upgrade process to upgrade the SRB system. Because upgrade files are typically large, the upgrade process can be split into multiple upgrade data packets, such as upgrade data packet 1, upgrade data packet 2, ..., and upgrade data packet 1000. Each upgrade data packet is then transmitted to each device in the SRB system to be upgraded.

[0064] Specifically, when transmitting the upgrade data message, the target device can receive the upgrade data message sent by the PC or other devices in the SRB system.

[0065] In a practical scenario, taking the target device as device 2, device 2 can receive an upgrade data message sent by the PC, such as receiving upgrade data message 1. In one implementation of the present application, in order for device 2 to subsequently use the upgrade data message to perform an upgrade operation, the upgrade data messages can be stored in the order in which they were received. If the currently received upgrade data message is upgrade data message 1, it is directly stored in the database. If the currently received upgrade data message is upgrade data message 2, it is stored in the database after the received upgrade data message 1.

[0066] In addition, based on the characteristics of the SRB bus (forwarding as long as the source of the message is not itself), device 2 can also receive the upgrade data message transmitted by device 1 and device 3.

[0067] If the target device is a device other than device 2, such as device 1, then according to the communication relationship between devices in the SRB system and the characteristics of the SRB bus, device 1 can receive the upgrade data message transmitted by device 2 and device 4.

[0068] S12. Determine whether the upgrade data message is received through a non-SRB communication port; if so, execute step S13; if not, execute step S14.

[0069] Specifically, the non-SRB communication port refers to a port other than the SRB communication port, and in this embodiment, refers to an Ethernet port connected to a PC.

[0070] If the upgrade data message is received through a non-SRB communication port, the target device is device 2 connected to the PC. If the upgrade data message is received through an SRB communication port, the target device is any device in the SRB system, which can be device 2 connected to the PC or devices 1, 3, and 4 not connected to the PC.

[0071] S13: Forward the upgrade data message to other devices connected to the target device through each SRB communication port.

[0072] Specifically, when the upgrade data message is received through a non-SRB communication port, it means that the target device at this time is device 2 connected to the PC, and the upgrade data message is the upgrade data message transmitted by the PC to device 2 through the Ethernet port, such as the PC transmits upgrade data message 1 to device 2 through the Ethernet port.

[0073] At this time, refer to Figure 4 Since Device 2 is the first device in the SRB system to receive Update Data Message 1, it needs to forward Update Data Message 1 to other devices in the SRB system. Since Port A of Device 2 is connected to Port B of Device 1, and Port B of Device 2 is connected to Port A of Device 3, Port A can be used to transmit Update Data Message 1 to Port B of Device 1, allowing Device 1 to receive Update Data Message 1 and perform the corresponding storage operation. Furthermore, Port B will also be used to transmit Update Data Message 1 to Port A of Device 3, allowing Device 3 to receive Update Data Message 1 and perform the corresponding storage operation.

[0074] After successfully sending upgrade data packet 1 to device 2, the PC can continue to transmit upgrade data packet 2 to device 2. After successfully sending upgrade data packet 2 to device 2, the PC can continue to transmit upgrade data packet 3 to device 2... until the upgrade data packet 1000 is successfully sent to device 2.

[0075] S14: Forward the upgrade data message to other devices connected to the target device through the target communication port.

[0076] The target communication port is another port among the SRB communication ports configured for the device except the port for receiving the upgrade data message.

[0077] Specifically, when the upgrade data message is not received through a non-SRB communication port, it means that the upgrade data message is received through an SRB communication port. In this case, the target device is any device in the SRB system, which can be device 2 connected to the PC, or devices 1, 3, and 4 not connected to the PC. However, the upgrade data message must be received through an SRB communication port.

[0078] For example, if the target device is device 1, according to the above example, port B of device 1 can receive upgrade data message 1 sent by port A of device 2. Port B of device 1 is an SRB communication port, which meets the requirement that the upgrade data message is received through the SRB communication port.

[0079] Since port A of device 1 is connected to port B of device 4, and port B of device 1 is connected to port A of device 2, and since device 2 already has upgrade data packet 1, device 1 no longer needs to send upgrade data packet 1 to device 2. Therefore, device 1 can use a port other than the port that receives the upgrade data packet, that is, port A, to send upgrade data packet 1 to port B of device 4. Port 4 receives the upgrade data packet 1 and stores it locally.

[0080] S15. Perform an upgrade operation based on the upgrade data message.

[0081] In this embodiment, the upgrade operation can be performed after all upgrade data messages sent by the PC are completely received.

[0082] In one implementation, if the upgrade data message is the last upgrade data message sent by the PC, that is, when it is determined that the upgrade data message is the last upgrade data message, the data to be upgraded is obtained based on all received upgrade data messages.

[0083] Specifically, all upgrade data messages can be parsed to obtain message content, and based on the message content, the data to be upgraded, such as the aforementioned files to be upgraded, can be combined to perform the upgrade operation. During the upgrade, the local files to be upgraded can be deleted and the newly received files to be upgraded can be stored locally to complete the upgrade operation.

[0084] In this embodiment, an upgrade data message is obtained. When the upgrade data message is received through a non-SRB communication port, the upgrade data message is forwarded to other devices connected to the target device through each SRB communication port. When the upgrade data message is received through an SRB communication port, the upgrade data message is forwarded to other devices connected to the target device through a target communication port. The target communication port is an SRB communication port configured for the device other than the port for receiving the upgrade data message. Through this method of forwarding the upgrade data message, the present invention only needs to send the upgrade data message to one of the devices in the SRB system, and each device in the SRB system can receive the upgrade data message through the above-mentioned communication method, complete the upgrade operation, and improve the efficiency of device upgrades.

[0085] In another implementation of this application, Figure 4Taking the upgrade data packet as an example, let's describe the entire upgrade data packet transmission process. After receiving the upgrade data packet, device 2 obtains and saves a copy, then forwards it through the SRB ports (Port A and Port B). After receiving the upgrade data packet, devices 1 and 3 also obtain and save a copy. Then, leveraging the characteristics of the SRB bus (forwarding the packet as long as it is not from their own source), they forward it through another port (Device 1 forwards it through Port A, and Device 3 forwards it through Port B).

[0086] Since both devices 1 and 3 forwarded the upgrade data message to device 4, device 4 now receives two identical upgrade data messages. To avoid duplicate message processing, in one implementation of the present application, if it is determined that multiple identical upgrade data messages have been received, the other upgrade data messages that follow the first of the multiple identical upgrade data messages are discarded.

[0087] Specifically, if the target device is device 4, after receiving the same upgrade data message sent by devices 1 and 3, the SRB bus feature (same message filtering mechanism) is used to retain the upgrade data message received earlier and discard the upgrade data message received later.

[0088] After receiving the upgrade data message, device 4 forwards it to device 1 via port B, which then forwards it to device 3 via port A. Device 1 then forwards it to device 2 via port B. Similarly, device 3 forwards it to device 2 via port A, and device 2 receives the same upgrade data message again. Based on the identical message filtering mechanism, only the upgrade data message received earlier is retained. At this point, since device 2 has already forwarded the message, continuing to forward the message will result in duplicate forwarding of the message. Therefore, in one implementation of the present application, if it is determined that the upgrade data message has already been forwarded by the target device, the upgrade data message is discarded.

[0089] Specifically, if device 2 determines that the upgrade data message has been forwarded to device 1 and device 3, device 2 directly discards the upgrade data message, and forwarding of the upgrade data message ends.

[0090] For the next upgrade data message, the above process is repeated until all messages are received (messages 1-1000 to be upgraded are received), forming a complete file to be upgraded. The device then automatically replaces the latest file to complete the upgrade.

[0091] Through the above steps, as long as any device in the SRB system is connected to at least one other device, the PC only needs to send the upgrade message once. Through the above forwarding operation, all devices in the SRB system (device 2, device 1, device 3, and device 4) can receive the sent message, improving the efficiency and convenience of the upgrade and simplifying the upgrade process, making it simple, convenient, and efficient for all devices in the SRB system to upgrade. In addition, during the upgrade process, devices 1, 3, and 4 receive two copies of the same message. This redundant message forwarding avoids the problem of failed message reception due to a communication anomaly, which could lead to an upgrade failure, thereby improving upgrade reliability.

[0092] It should be noted that for the same topology structure, such as a linear topology and a star topology, the device upgrade method applied to the SRB system in the embodiment of the present invention can still be adopted.

[0093] In another implementation of the present application, for an SRB system, to avoid conflicts caused by centralized message transmission, devices within the SRB system have different message transmission times. Therefore, in this embodiment, when forwarding the upgrade data message to other devices connected to the target device via each SRB communication port, a message transmission time period for the target device may be determined, and the upgrade data message may be forwarded to the other devices connected to the target device via each SRB communication port during the message transmission time period.

[0094] Specifically, SRB is based on Ethernet technology and is modified for communication determinism and real-time performance. Its principle is as follows: Figure 6 As shown:

[0095] First, divide the communication time into several consecutive equal-length time segments, called macrocycles. Each macrocycle is divided into two parts: cycle time and aperiodic time. Cycle time is used to send periodic data, while aperiodic time is used to send non-periodic data, such as emergency data.

[0096] Furthermore, the cycle time is divided into a corresponding number of time slices based on the number of devices in the SRB system, with each device assigned a time slice. Depending on the amount of data a device needs to send, the time slice length can be set to different values ​​for each device. The larger the amount of data sent, the longer the time slice allocated.

[0097] like Figure 7 As shown, the SRB scheduling principle is as follows:

[0098] Suppose there are four devices in the SRB system, namely device 1, 2, 3, and 4. The cycle time is divided into four time slices. The lengths of the four time slices can be different but cannot overlap. They are allocated to the four devices. For example, if Tm is the start time of the macro cycle, the time slice lengths of device 1, device 2, device 3, and device 4 are t1, t2, t3, and t4 respectively. Then the start time of device 1's time slice can be configured as Tm, the start time of device 2's time slice can be set to Tm+t1, the start time of device 3's time slice can be set to Tm+t1+t2, and the start time of device 4's time slice can be set to Tm+t1+t2+t3.

[0099] When the sending start time of device 1 arrives, if device 1 has periodic data to send, it can send the periodic data. If it does not send it in its own time slice, it must wait until its own time slice of the next macro cycle to send it. If it has non-periodic data to send, it sends a non-periodic data declaration message. Devices 2, 3 and 4 follow the same rule: each device can only send periodic data in its own sending time slice.

[0100] During the non-periodic time period, based on the priorities in the non-periodic data declaration messages sent by devices 1, 2, 3, and 4, the device with a higher priority preferentially uses the non-periodic time to send data, for example, to send urgent data.

[0101] Therefore, in this embodiment, when sending the upgrade data message, the target device can send the corresponding upgrade data message within the corresponding time slice, or send the corresponding upgrade data message within the non-periodic time and within the time period corresponding to the assigned priority order.

[0102] In actual scenarios, a device may need to send two upgrade data packets simultaneously. If these two upgrade data packets need to be output from the same port, for example, for device 1, two upgrade data packets need to be output from port A, then one upgrade data packet can be sent in one macrocycle and the next upgrade data packet can be sent in the next macrocycle. In addition, if these two upgrade data packets need to be output from different ports, each port can send data according to its corresponding time slice.

[0103] In this embodiment, different devices send data within corresponding time slices, which can avoid message conflicts caused by centralized data transmission.

[0104] Based on the embodiment of the device upgrade method described above, another embodiment of the present application provides a device upgrade apparatus applied to an SRB system, which is applied to a target device in the SRB system, wherein the target device is any device in the SRB system. Figure 8, the equipment upgrade device applied to the SRB system includes:

[0105] The message acquisition module 11 is used to obtain the upgrade data message;

[0106] A first forwarding module 12 is configured to forward the upgrade data message to other devices connected to the target device through each SRB communication port when the upgrade data message is received through a non-SRB communication port;

[0107] A second forwarding module 13 is configured to forward the upgrade data message to other devices connected to the target device through a target communication port when the upgrade data message is received through an SRB communication port; the target communication port is another port among the SRB communication ports configured for the device except the port for receiving the upgrade data message;

[0118] In the case that it is determined that the upgrade data message is the last upgrade data message, data to be upgraded is obtained based on all received upgrade data messages, and an upgrade operation is performed using the data to be upgraded.

[0119] In this embodiment, an upgrade data message is obtained. When the upgrade data message is received through a non-SRB communication port, the upgrade data message is forwarded to other devices connected to the target device through each SRB communication port. When the upgrade data message is received through an SRB communication port, the upgrade data message is forwarded to other devices connected to the target device through a target communication port. The target communication port is an SRB communication port configured for the device other than the port for receiving the upgrade data message. Through this method of forwarding the upgrade data message, the present invention only needs to send the upgrade data message to one of the devices in the SRB system, and each device in the SRB system can receive the upgrade data message through the above-mentioned communication method, complete the upgrade operation, and improve the efficiency of device upgrades.
