Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of a communication method, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 2 is a communication method according to an embodiment of the present invention, which is applied to any one of the communication devices in the communication system as shown in fig. 3, 4 or 5. As shown in fig. 2, the method comprises the steps of:
step S202, a first target device receives target data transmitted by a second target device through a target communication loop, wherein the first target device and the second target device are positioned in the target communication loop, the second target device is a device adjacent to the first target device, and any two adjacent devices in the target communication loop are directly connected through a communication link;
it should be noted that the first target device may be any communication device in the target communication loop, and the second target device is a target device adjacent to the first target device in the target communication loop, where the adjacent to the first target device in this application means that the second target device and the third target device are directly connected through a communication line.
In some embodiments of the present application, three or more communication devices may be included in the target communication loop. Taking the number of communication devices included in the target communication loop as three as an example, it is assumed that the devices in the target communication loop are communication device a, communication device B, and communication device C, respectively, and that communication device a is directly connected to communication device B and communication device C through a communication line, and communication device B is also directly connected to communication device C through a communication line. At this time, any communication apparatus may be used as the first target communication apparatus in step S202 described above for the communication apparatus a, the communication apparatus B, and the communication apparatus C. For example, in the case where the communication device a is a first target communication device, the communication device B or the communication device C may be a second target communication device. The same applies to the communication device B or the communication device C as the first target communication device.
It should be noted that in the communication scheme provided in the present application, the second target communication device may also receive the target data transferred by the first target communication device, that is, in the communication scheme provided in the present application, the adjacent communication devices may transfer data to each other.
As an alternative implementation, the target communication loop may include a first target communication loop and a second target communication loop, and the first target communication loop and the second target communication loop include the same devices, except that the data transmission direction is opposite. For example, when the data transmission direction in the first destination communication loop is clockwise, the data transmission direction in the second destination communication loop is counterclockwise.
In some embodiments of the present application, for a communication system including a first target communication loop and a second target communication loop, when receiving target data transmitted by a second communication device, a first communication device in the communication system may determine a loop state of the first target communication loop, where the first target communication loop is a communication loop passing through the first target device, the second target device, and a third target device, a data transmission direction in the first target communication loop is a first transmission direction, and the first transmission direction is a transmission direction from the second target device to the first target device, and then from the first target device to the third target device; then when the loop state of the first target communication loop is determined to be a fault-free state, the first target device receives target data transmitted by the second target device through the first target communication loop; and when the loop state is determined to be the fault state, the first target communication device receives target data transmitted by a second target device through a second target communication loop, wherein the second target communication loop is a communication loop passing through the first target device, the second target device and a third target device, the data transmission direction in the second target communication loop is a second transmission direction, and the second transmission direction is transmitted to the first target device from the third target device and then transmitted to the second target device from the first target device.
As an alternative embodiment, the loop status of the first target communication loop may be determined by the following method; determining that a loop state of the first target communication loop is a non-fault state under the condition that the first communication device receives the target data within a preset time period; and determining that the loop state of the first target communication loop is a fault state under the condition that the first communication device does not receive the target data within the preset time period.
Specifically, after the first target device successfully receives the target data transmitted by the second target device, the first target device feeds back to the second target device an indication message for indicating successful reception of the target data. When the indication information fed back by the first target device is not received within the preset time period, it can be determined that the first target communication loop has a fault, and at this time, the second target device transmits target data to the first target device through the second target communication loop.
It should be noted that, at this time, the second target device does not directly transfer the target data to the first target device, but first transfers the target data to a device adjacent to the second target device except the first target device, and then the device transfers the target data to a next target device according to the data transfer direction in the second target communication loop until the target data is transferred to a third target device, and then the third target device transfers the target data to the first target device, wherein the third target device is another device adjacent to the first target device.
In some embodiments of the present application, in addition to the first target communication loop and the second target communication loop, a switch may be further provided in the communication network, wherein the switch is connected to each communication device, and the switch is in a dormant state when the first target communication loop or the second target communication loop can normally operate, and the switch can normally operate only when both the first target communication loop and the second target communication loop fail. Specifically, when the link states of a first target communication loop and a second target communication loop are both fault states, a first target communication device receives the target data transmitted by a second target device through a target switch, where the target switch is a switch connected to the first target communication device and the second target communication device.
Step S204, determining target equipment corresponding to the target data, wherein the target equipment is equipment for receiving and processing the target data;
in some embodiments of the present application, the target data includes first device identification information and second device identification information, where the first device identification information is device identification information of a device that generates the target data, and the second device identification information is device identification information of the destination device, and determining the destination device corresponding to the target data includes: determining the second device identification information in the target data; and determining the target equipment corresponding to the target data according to the second equipment identification information.
Specifically, the target data may be transmitted in the form of a data packet in the target communication loop, wherein the first device identification information and the second device identification information may be carried by a packet header of the data packet.
As an alternative implementation, a corresponding data area may be set in a data packet in a customized manner for each device in the target communication loop, and each data area includes a source end identifier, a destination end identifier and valid data to be transmitted. For example, as shown in the following table, assuming that four devices are included in the target communication loop, corresponding labels 0x00, 0x01, 0x02, and 0x03 may be set in the data packet for each device, and the data in the data packet may be divided into 4 regions, each region being 1024 bytes, where the first byte represents the source end label, that is, the device label of the data transmitting end of the region; the second byte is the destination label, i.e. the device label at the receiving end of the region data, and the last 1022 bytes are the valid data of the region, i.e. the valid data to be transmitted by the device to the destination device.
| Address | Source end label | Destination end number | Valid data |
| 0-1023 | 0x00 | 0x02 | |
| 1024-2047 | 0x01 | 0x03 | |
| 2048-3071 | 0x02 | 0x00 | |
| 3072-4095 | 0x03 | 0x01 |
In some embodiments of the present application, when determining a destination device corresponding to the target data, in order to improve communication efficiency, the target data may be copied to obtain mirror image data of the target data, and the target data is sent to the third target communication device; and determining the target equipment corresponding to the target data according to the mirror image data.
In addition, in some embodiments of the present application, the target communication loop may also be constructed between different processors in the same device, in which case, each processor may be regarded as an independent device, thereby implementing the communication method provided in the present application in a device including multiple processors. For example, if a video processing device internally includes a first processor responsible for acquiring images, a second processor responsible for optimizing the images, and a third processor responsible for editing the images, the target communication loop can be established among the three processors, so as to realize mutual communication among different processors.
Step S206, under the condition that the first target device is the target device, processing the target data; and in the event that the target data is not the destination device, communicating the target data to a third target device, wherein the third target device is a device in the target communication loop other than the second target device and adjacent to the first target device.
In some embodiments of the present application, in the case where the first target device is the destination device, processing the target data comprises: determining and recording the first device identification information in the target data; and determining first valid data carried in the target data, wherein the first valid data comprises at least one of the following data: device control instructions, multimedia data.
In some embodiments of the present application, after determining valid data carried in the target data, the first target device may further write second valid data in the target data, and update the first device identification information and the second device identification information in the target data; and sending the target data to the third target equipment.
Optionally, in a case that the destination device of the target data is not a third target device, the target data is transferred by the third target device to a fourth target device, and the fourth target device is a device in the target communication loop, except for the first target device, and adjacent to the third target device.
Specifically, the target data is transmitted in the form of data packets in the communication loop. The packet may divide a plurality of data storage areas within the packet according to the number of devices in the communication loop. For example, if the total number of bytes of data that can be accommodated by the data packet is 4096 bytes and the number of devices in the communication circuit is four, the 0 th to 1023 th bytes in the data packet may correspond to the data generated by the first device, the 1024 th to 2047 th bytes may correspond to the data generated by the second device, the 2048 th to 3071 th bytes may correspond to the data generated by the third device, and the 3072 th to 4095 th bytes may correspond to the data generated by the fourth device. After each device in the communication loop receives a data packet corresponding to target data, when it is determined that new data needs to be written in the data packet, the newly generated data is written in a storage area corresponding to each device in the data packet, and the newly generated data is written to cover original old data in the storage area. In this way, the time consumed by the device in generating the data packet can be reduced, thereby improving the overall communication efficiency.
In some embodiments of the present application, updating the first device identification information and the second device identification information in the target data comprises: determining third device identification information corresponding to the first target device and fourth device identification information of the target device corresponding to the second valid data; determining that the third device identification information is the first device identification information, and determining that the fourth device identification information is the second device identification information.
Receiving target data transmitted by a second target device through a target communication loop by using a first target device, wherein the first target device and the second target device are positioned in the target communication loop, the second target device is a device adjacent to the first target device, and any two adjacent devices in the target communication loop are directly connected through a communication link; determining target equipment corresponding to the target data, wherein the target equipment is equipment for receiving and processing the target data; under the condition that the first target device is the target device, the target data is processed in a mode that a communication loop comprising a plurality of target devices is established and adjacent devices in the communication loop are directly connected through a communication link, so that the aim of avoiding the devices from communicating only through a switch is fulfilled, the technical effect of avoiding the breakdown of the whole communication network under the condition that the switch breaks down is achieved, and the technical problem of low stability of the communication network caused by the communication network adopting a star-type topological structure in the related technology is solved.
Example 2
According to an embodiment of the present invention, an embodiment of a communication system is provided. Fig. 3 is a schematic structural diagram of a communication system provided according to an embodiment of the present invention. As shown in fig. 3, the communication system is composed of a plurality of communication devices 30, each communication device 30 of the plurality of communication devices 30 is operable to execute the communication method described in embodiment 1, and each communication device 30 constitutes a first communication loop and a second communication loop with the communication device 30 adjacent to each communication device 30 through a communication link, wherein the data transmission directions in the first communication loop and the second communication loop are different
According to an embodiment of the present invention, another embodiment of a communication system is provided. Fig. 4 is a schematic structural diagram of a communication system provided according to an embodiment of the present invention. As shown in fig. 4, the communication system includes: a plurality of communication devices 30, a switch 32, wherein, like the communication system shown in fig. 3, each communication device 30 of the plurality of communication devices 30 within the communication system shown in fig. 4 is operable to execute the communication method described in embodiment 1, and each communication device 30 constitutes a first communication loop and a second communication loop with the communication device 30 adjacent to each communication device 30 through a communication link, wherein the data transmission directions in the first communication loop and the second communication loop are different; a switch connected to each of the plurality of communication devices 30.
In some embodiments of the present application, the communication link may further include a converter corresponding to a data interface of the communication device, and the connection and data interaction between the communication link of the first interface type and the data interface of the communication device of the second interface type may be implemented.
As can be seen from fig. 4, since the embodiment of the present application includes two ring communication loops and one switch, the communication system provided by the embodiment of the present application has higher stability compared to the related art. Specifically, when a first communication loop fails, the communication system can continue communication through a second communication loop. When the first communication loop and the second communication loop both fail, communication between different devices can be realized through the switch.
When the communication devices 30 in the communication system communicate through the switch, each communication device 30 is connected to the network switch by taking the network switch as a center, the MAC address and the IP address of each communication device 30 are determined, and each communication device 30 sends and receives a corresponding data packet through a network communication protocol. For example, when the first communication device needs to send command data to the second communication device, the first communication device may package, according to the UDP protocol, the source MAC address and the IP address of the first communication device, and the destination MAC address and the IP address of the second communication device, fill the command data to be sent in valid data bits of the UDP protocol, and send the command data to the network switch after the network packet is formed. When the second communication device detects that the destination MAC and IP of the UDP packet received by the RX end are the MAC and IP of the second communication device, the second communication device receives the packet data and analyzes the source MAC and IP at the same time, thereby judging which communication device the data packet comes from. And the effective data bit of the UDP packet is analyzed to be command data sent to the second communication equipment by the first communication equipment, and the packet data transmission is finished.
Specifically, taking the communication system shown in fig. 5 as an example, the FPGA and the MCU are bridged by the network transceiver and the converter, so that the ARM and the MCU can receive and transmit network signals, and the FPGA and the ARM are directly connected by the RGMII bus. Therefore, annular communication links in the clockwise direction and the anticlockwise direction are formed among the three devices, one communication link is a main communication link, the other communication link is a backup link, when the main communication link fails, the backup link can be started, and the stability of the system is high.
Taking a clockwise communication loop as an example, the TX end of the FPGA sends a data packet to the ARM, and the RX end receives the data packet sent by the MCU; the TX end of the ARM sends the data packet to the MCU, and the RX end receives the data packet sent by the FPGA; and the TX end of the MCU sends the data packet to the FPGA, and the RX end receives the data packet sent by the ARM. Each device analyzes the data information sent to itself from the received data packet, and fills the data information to be sent into the data packet and sends the data information to the next level. Therefore, the three devices can realize arbitrary communication in pairs without participation of a network switch. And when a clockwise communication link fails, the same functionality can be achieved using a counterclockwise communication loop.
And when the two communication loops are in failure, the FPGA, the ARM and the MCU can use the network switching chip as the center of the communication structure. Specifically, the three devices are connected to the switch after being bridged by the network transceiver chip. The three devices respectively send the data packets to the network switching chip and receive the data packets from the network switching chip, so that the three devices can communicate with each other arbitrarily.
It should be noted that the communication system shown in fig. 5 may also be a communication system formed by connecting different processing modules in the same device, in this case, the communication device in the communication method described in embodiment 1 is identical to the processing module in fig. 5, that is, any processing module in fig. 5 may execute the communication method in embodiment 1.
It should be noted that, since the communication system provided in this embodiment can be used to execute the communication method in embodiment 1, the explanation about the communication method in embodiment 1 is also applicable to this embodiment, and is not described herein again.
