[0020] The above and / or additional aspects and advantages of the present application will become apparent and easily understood from the following description of the embodiments in conjunction with the accompanying drawings, in which:

[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] In related technologies, in order to meet the needs of control and information transmission, computer communication systems often need to establish communications with external related systems and devices to achieve the purpose of sending and receiving control instructions. In actual application, a single computer communication system or device (such as an automotive electronic control unit ECU) often needs to deploy multiple functions or algorithms, and most of the above functions and algorithms are asynchronous and periodic, and generate a large number of control instructions (communication messages) of different types and different sending cycles.

[0026] Since the above communication messages need to be sent to the outside asynchronously and periodically, if they are not properly scheduled, it is easy to cause a short-term clustering of communication messages, and in extreme cases, even cause the loss of sent communication messages. For fields such as energy, transportation, security, industrial robots, etc. involving the safety of public life and property, the above problems are unacceptable, so it is necessary to take corresponding measures to prevent them.

[0027] Please refer to the accompanying drawings to describe the communication traffic balancing method, communication component, computer communication system, vehicle and storage medium of the embodiment of the present application. In view of the above-mentioned problem that it is easy to cause a short-term communication message clustering phenomenon without reasonable scheduling, and even cause the loss of sent communication messages in extreme cases, the present application provides a communication traffic balancing method, in which the message bias of each communication message is determined by a scheduling table, so that the sending time of each communication message can be reasonably arranged. As a result, the problems of short-term communication message clustering phenomenon, communication message loss, etc. are solved.

[0028] Specifically, Figure 1 A flow chart of a communication traffic balancing method provided in an embodiment of the present application.

[0029] See also Figure 1 , the communication traffic balancing method comprises the following steps:

[0030] Step S01: Acquire a communication configuration table, the communication configuration table including a basic cycle of a computer communication system and a message cycle of each communication message, wherein the message cycle of a communication message is a sending cycle of the communication message;

[0031] Step S02: Generate a scheduling table according to the communication configuration table, the scheduling table including the message offset of each communication message, wherein the message offset of the communication message is the number of basic cycles required to be offset after the communication message reaches the message cycle;

[0032] Step S03: periodically encapsulate communication messages according to the scheduling table and send the communication messages to the associated system.

[0033] The present application discloses a communication component, and the communication flow balancing method of the implementation mode of the present application can be implemented by the communication component of the implementation mode of the present application. That is to say, the communication component is used to: obtain a communication configuration table, the communication configuration table includes the basic cycle of the computer communication system and the message cycle of each communication message, wherein the message cycle of the communication message is the sending cycle of the communication message; generate a scheduling table according to the communication configuration table, the scheduling table includes the message offset of each communication message, wherein the message offset of the communication message is the number of basic cycles required for the communication message to be offset after the message cycle is reached; periodically encapsulate the communication message according to the scheduling table and send the communication message to the associated system.

[0034] The communication traffic balancing method and communication component of the implementation mode of the present application determine the message bias of each communication message through a scheduling table, so as to reasonably arrange the sending time of each communication message, avoid the phenomenon of communication message crowding, balance the communication load, and avoid the loss of communication messages.

[0035] See also Figure 2 In some implementations, a communication configuration table may be obtained. The communication configuration table may be obtained by parsing a configuration file and generating a communication configuration table, and then generating a scheduling table based on multiple information in the communication configuration table. The communication configuration table includes but is not limited to the basic cycle of the computer communication system and the message cycle of each communication message. The basic cycle can be expressed as T basic Indicates that T basic It can be a common divisor of all message cycles, such as the greatest common divisor, 1 / 2 of the greatest common divisor, 1 / 4 of the greatest common divisor, etc. The computer communication system will use this as a cycle to periodically scan the communication schedule and send the communication messages that need to be sent. The message cycle can be expressed as T tx Indicates that T tx The sending cycle of each communication message.

[0036] In some implementations, the communication configuration table also includes configuration items such as the communication message identifier, physical destination address, logical destination address, message size, system throughput, communication bandwidth, etc. It is worth mentioning that system performance parameters such as system throughput and communication bandwidth can be used to implement the load warning function.

[0037] It should be noted that the number of communication messages in the configuration file, the above-mentioned configuration items of each communication message, and the system performance parameters are strongly related to the specific application project requirements and the system's underlying software and hardware performance. Therefore, the configuration file can be generated by the application developer based on the actual project requirements.

[0038] In this way, application developers generate configuration files, and applications can transmit data from multiple applications to the communication component, which can configure parsing, schedule table generation, sending schedules, and load warnings. The communication message is then transmitted to the associated system through the network, which includes but is not limited to Ethernet, Controller Area Network (CAN), and Local Interconnect Network (LIN). For details on the composition of computer communication systems and their external connections, please refer to Figure 3 , the computer communication system 200 of the present application may be an embedded system.

[0039] Then, a scheduling table is generated based on the multiple information in the communication configuration table, and the scheduling table includes the message offset of each communication message. The message offset can be expressed by P offset Indicates that Poffset The number of basic cycles required to offset each communication message after the message cycle arrives. Finally, the communication message can be periodically encapsulated according to the scheduling table and sent to the associated system. In this way, the phenomenon of communication message clustering can be avoided, the communication load is balanced, and the loss of communication messages can be avoided.

[0040] It is worth mentioning that in related technologies, in order to meet the timeliness and security requirements of the control system, most of the upper-level applications and algorithms run periodically with time as the trigger condition. Therefore, they will also periodically generate various control instructions and package them into communication messages of a certain format and send them to external related systems. Usually, the upper-level applications and algorithms run asynchronously, and the operation cycles are different. If the sending of the communication messages they generate is not reasonably scheduled, the number of messages sent by the system at the lowest common multiple of all message cycles will reach a peak, and the number of communication messages required to be sent by the system at other times may be much lower than this. With the increase of system integrated functions, the amount of communication messages at peak times is most likely to exceed the system's throughput capacity and cause some communication messages to be lost.

[0041] In short, the uncontrolled asynchronous and periodic transmission of communication messages will cause load imbalance in the system, which can easily lead to the loss of communication messages and affect the system control function, which is unacceptable for embedded systems.

[0042] Please refer to Table 1 and Figure 4 Table 1 shows the distribution of communication messages sent by the ECU at each moment, taking the deployment of an automotive electronic control unit (SWC) as an example in the related art. Figure 4 It is a schematic diagram of communication load distribution in related technologies. Figure 4 It can be seen that the system load reaches the maximum at n*100ms (n is a non-negative integer), and the load is the smallest at n*100+10ms, n*100+30ms, n*100+70ms, n*100+90ms, etc., and the system load fluctuates greatly between peak and trough periods, resulting in load imbalance.

[0045] In one embodiment, the communication traffic balancing method of the embodiment of the present application can be applied to Ethernet. Therefore, the specific communication configuration table can be found in Table 2 below.

[0046] Table 2

[0047]

[0048] It can be seen from Table 2 above that the basic period is 10 ms. Table 2 includes 10 communication messages, each of which has a corresponding communication message identifier. Among them, the message period of the communication message with the communication message identifier 1001 is 10, the message period of the communication message with the communication message identifier 1101 is 20, the message period of the communication message with the communication message identifier 1102 is 20, the message period of the communication message with the communication message identifier 1201 is 50, the message period of the communication message with the communication message identifier 1202 is 50, the message period of the communication message with the communication message identifier 1205 is 50, the message period of the communication message with the communication message identifier 1204 is 50, the message period of the communication message with the communication message identifier 1301 is 100, the message period of the communication message with the communication message identifier 1302 is 100, and the message period of the communication message with the communication message identifier 1303 is 100.

[0049] Each communication message has a corresponding communication message identifier, and a scheduling table can be generated according to the communication configuration table, the scheduling table including the message offset of each communication message. The specific scheduling table can be found in Table 3 below.

[0050] Table 3

[0051] Communication message identification Belonging to SWC Message cycle (ms) Message interval Message offset P1(1001) SWC1 10 1 0 P2(1101) SWC2 20 2 0 P3(1102) SWC2 20 2 1 P4(1201) SWC3 50 5 0 P5(1202) SWC3 50 5 1 P6(1203) SWC3 50 5 2 P7(1204) SWC3 50 5 3 P8(1301) SWC4 100 10 0 P9(1302) SWC4 100 10 1 P10(1303) SWC4 100 10 2

[0052] As can be seen from Table 3 above, Table 3 includes 10 communication messages and message offsets of 10 communication messages. Among them, the communication message with the communication message identifier 1001 can be P1, and the message offset of P1 is 0; the communication message with the communication message identifier 1101 can be P2, and the message offset of P2 is 0; the communication message with the communication message identifier 1102 can be P3, and the message offset of P3 is 1; the communication message with the communication message identifier 1201 can be P4, and the message offset of P4 is 0; the communication message with the communication message identifier 1202 can be P5, and the message offset of P5 is 1 ; The communication message with the communication message identifier 1205 can be P6, and the message bias of P6 is 2; the communication message with the communication message identifier 1204 can be P7, and the message bias of P7 is 3; the communication message with the communication message identifier 1301 can be P8, and the message bias of P8 is 0; the communication message with the communication message identifier 1302 can be P9, and the message bias of P9 is 1; the communication message with the communication message identifier 1303 can be P10, and the message bias of P10 is 2.

[0053] The message bias of each communication message can be determined according to the scheduling table in Table 3. For example, the message bias of P1 (1001) is determined to be 0, the message bias of P2 (1101) is determined to be 0, the message bias of communication message P3 (1102) is determined to be 1, and so on. In this way, the sending time of each communication message can be reasonably arranged to avoid the phenomenon of communication message crowding, balance the communication load, and avoid the loss of communication messages.

[0054] Please also read Figure 4 and 5 It can be understood that after using the communication traffic balancing method of the embodiment of the present application, the distribution of the communication messages sent by the ECU at each moment is as follows: Figure 5 As shown, the load peak and load valley are 4 and 2 respectively, and no load balancing is performed (such as Figure 4 As shown in Figure 2, the load peak and load valley are 10 and 1 respectively, and the optimization effect is more obvious.

[0055] See also Figure 6 In some embodiments, step S02 includes:

[0056] Step S021: traverse the communication configuration table;

[0057] Step S022: obtaining the current message period of the current communication message from the communication configuration table;

[0058] Step S023: determining the number of communication messages whose message period is currently counted in the process of traversing the communication configuration table as the current statistical number;

[0059] Step S024: Calculate the ratio of the current message period to the basic period as the current message interval;

[0060] Step S025: Calculate the remainder of the current statistical quantity divided by the current message interval as the current message offset;

[0061] Step S026: Write the current message interval and the current message offset into the scheduling table.

[0062] The communication flow balancing method of the embodiment of the present application can be implemented by the communication component of the embodiment of the present application. That is, the communication component is used to: traverse the communication configuration table; obtain the current message period of the current communication message from the communication configuration table; determine the number of communication messages whose message period is currently counted as the current message period in the process of traversing the communication configuration table as the current statistical quantity; calculate the ratio of the current message period to the basic period as the current message interval; calculate the remainder of the current statistical quantity and the current message interval as the current message offset; write the current message interval and the current message offset into the scheduling table.

[0063] Please also read Figure 7 And Table 2, Table 2 is a communication configuration table, and the current message period of the current communication message can be obtained in Table 2. In one embodiment, the communication message identified as P6 (1203) in Table 2 is used as the current communication message. The message period of the communication message identified as P6 (1203) is the current message period. It can be known that the current message period is 50 and the basic period is 10ms. The ratio of the current message period and the basic period is calculated as the current message interval, and the current message interval is 5. In the process of traversing the communication configuration table, for example, the message period of the communication message identified as P4 (1201) and P5 (1202) is the same as P6 (1203), so the current statistical quantity is calculated to be 2. The remainder of dividing the current statistical quantity of 2 by the current message interval of 5 is 2, and 2 is the current message offset. In this way, the current message interval 5 and the current message offset 2 of the communication message with the communication message identifier P6 (1203) can be written into the scheduling table.

[0064] The communication configuration table can be traversed to calculate the message interval and message offset of each communication message, so that the sending time of each communication message can be reasonably arranged to avoid the phenomenon of communication message crowding, balance the communication load, and avoid communication message loss.

[0065] The above embodiments are combined with Figure 7 It can be seen that the communication message with the communication message identifier P6 (1203) is the current communication message, that is, Figure 7 In the i-th communication message, i is equal to 6. interval is the current message interval, where P interval =T tx / T basic The current message interval is the number of basic cycles required for each communication message to be sent twice, and is also the number of basic cycles that can be evenly divided into by the communication messages of the same period in each message period. offset is the message offset, the number of basic cycles required for each communication message to be offset after the message cycle arrives, P offse t∈[0, 1, 2, …, P interval -1].

[0066] It can be understood that i is the index of the message configuration item in the configuration table (for example, in P6, i=6), C txi The message period currently counted during the configuration table traversal is T txi The number of communication messages, expressed as C txi %P interval As the message offset P of the i-th message offset .

[0067] Please also read Figure 2 and Figure 8 In some implementations, the communication traffic balancing method further includes:

[0068] Step S04: traverse the scheduling table to perform load detection;

[0069] Step S05: judging whether there is overload according to the load detection result;

[0070] Step S06: In the event of overload, an alarm is issued.

[0071] The communication flow balancing method of the embodiment of the present application can be implemented by the communication component of the embodiment of the present application. That is, the communication component is used to: traverse the scheduling table to perform load detection; determine whether there is an overload according to the load detection result; and issue an alarm in the case of overload.

[0072] In one embodiment, the configuration file may include system performance parameters such as system throughput and communication bandwidth, parse the configuration file and generate a communication configuration table, and then generate a scheduling table based on the communication configuration table. In this way, the number of communication messages and the sending flow can be obtained by traversing the scheduling table, and then load detection can be performed. The load detection result can be used to determine whether there is an overload, and an alarm can be issued if there is an overload. In this way, the load early warning function can be realized.

[0073] Please also read Fig. 9 and Fig.10 In some embodiments, step S04 includes:

[0074] Step S041: Calculate the number of sent messages in each basic period within a characteristic period, where the characteristic period is the least common multiple of the message periods;

[0075] Step S05 includes:

[0076] Step S051: when the number of sent messages is greater than the system throughput, it is determined that there is an overload;

[0077] Step S052: When the number of sent messages is less than the system throughput, it is determined that there is no overload.

[0078] The communication flow balancing method of the embodiment of the present application can be implemented by the communication component of the embodiment of the present application. That is, the communication component is used to: calculate the number of sent messages in each basic period within a characteristic period, the characteristic period being the lowest common multiple of the message period; when the number of sent messages is greater than the system throughput, determine that there is an overload; when the number of sent messages is less than the system throughput, determine that there is no overload.

[0079] In one embodiment, a characteristic period can be 0-100ms, and the basic period is 10ms. Figure 5, the number of sent messages in the first basic cycle is 4. The characteristic cycle can be understood as the lowest common multiple of all message cycles. When the number of sent messages is greater than the system throughput, it is determined that there is an overload. The system throughput can be a preset value of the number of communication messages preset in advance, that is, when the number of sent messages is greater than the preset value, it is determined that there is an overload and an alarm is issued. When the number of sent messages is less than the preset value, it is determined that there is no overload.

[0080] See also Fig.10 , i is the serial number of the basic period within the characteristic period, L pkgi is the number of messages that need to be sent in the i-th basic cycle, L flowi is the sending traffic of the ith basic cycle.

[0081] See also Fig.11 and Fig.12 In some implementations, the scheduling table includes message intervals of each communication message, and step S041 includes:

[0082] Step S0411: determining whether the remainder of the first sequence number of the current basic cycle divided by the message interval of the current communication message is the message offset of the current communication message, wherein the first sequence number of the current basic cycle is the sequence number of the current basic cycle within the characteristic cycle;

[0083] Step S0412: when the remainder of the first sequence number of the current basic cycle divided by the message interval of the current communication message is the message offset of the current communication message, the number of sent messages is cumulatively increased by 1;

[0084] Step S0413: traverse all communication messages to determine the number of sent messages.

[0085] The communication flow balancing method of the embodiment of the present application can be implemented by the communication component of the embodiment of the present application. That is to say, the communication component is used to: determine whether the remainder of the first sequence number of the current basic cycle and the message interval of the current communication message is the message offset of the current communication message, wherein the first sequence number of the current basic cycle is the sequence number of the current basic cycle within the characteristic cycle; when the remainder of the first sequence number of the current basic cycle and the message interval of the current communication message is the message offset of the current communication message, the number of sent messages is cumulatively added by 1; and traverse all communication messages to determine the number of sent messages.

[0086] In one embodiment, the current basic cycle can be understood as the basic cycle for which the number of messages to be sent is to be determined. When the current basic cycle is the first basic cycle, the first sequence number may be 0; when the current basic cycle is the second basic cycle, the first sequence number may be 1; when the current basic cycle is the third basic cycle, the first sequence number may be 2; when the current basic cycle is the fourth basic cycle, the first sequence number may be 3; when the current basic cycle is the fifth basic cycle, the first sequence number may be 4.

[0087] It is determined whether a remainder obtained by dividing the first sequence number of the current basic cycle by the message interval of the current communication message is a message offset of the current communication message.

[0088] For example: the current basic cycle is the 6th basic cycle, the first sequence number can be 5, and the current communication message can be a communication message with a communication message identifier of P4 (1201). The ratio of the current message cycle to the basic cycle is calculated as the message interval, so the current message cycle 50 is divided by the basic cycle 10, and the message interval is 5. The remainder of the first sequence number 5 divided by the message interval 5 of P4 (1201) is 0, and the message offset of P4 (1201) is 0. Obviously, the remainder is the message offset of the current communication message, and the number of sent messages is accumulated and added by 1. In this way, all communication messages are traversed to determine the number of messages sent in the current basic cycle.

[0089] For another example: the current basic cycle is the fifth basic cycle, the first sequence number may be 4, and the current communication message may be a communication message with a communication message identifier of P6 (1203). The ratio of the current message cycle to the basic cycle is calculated as the message interval, so the current message cycle 50 is divided by the basic cycle 10, and the message interval is 5. The remainder of the first sequence number 4 divided by the message interval 5 of P6 (1203) is 4, and the message offset of P6 (1203) is 2. Obviously, the remainder is not the message offset of the current communication message, and it can be not counted. In this way, all communication messages are traversed to determine the number of messages sent in the current basic cycle.

[0092] Step S042: Calculate the sending flow of each basic period within a characteristic period, where the characteristic period is the least common multiple of the message period;

[0093] Step S05 includes:

[0095] Step S054: When the sending traffic is less than the communication bandwidth, it is determined that there is no overload.

[0096] The communication flow balancing method of the embodiment of the present application can be implemented by the communication component of the embodiment of the present application. That is, the communication component is used to: calculate the sending flow of each basic cycle within a characteristic period, the characteristic period is the lowest common multiple of the message period; when the sending flow is greater than the communication bandwidth, determine that there is an overload; when the sending flow is less than the communication bandwidth, determine that there is no overload.

Figure 5 , the number of sent messages in the first basic cycle is 4, and the sent communication messages are P1, P2, P4 and P8 respectively. The sending flow of each sent communication message can be understood as the message size of each sent communication message. The sending flow of the first basic cycle is 800 (100+100+200+400=800). The characteristic cycle can be understood as the lowest common multiple of all message cycles. When the sending flow is greater than the communication bandwidth, it is determined that there is an overload and an alarm is issued. When the sending flow is less than the communication bandwidth, it is determined that there is no overload.

[0103] In one embodiment, the current basic cycle is the sixth basic cycle, the first sequence number may be 5, and the current communication message may be a communication message with a communication message identifier of P4 (1201). The ratio of the current message cycle to the basic cycle is calculated as the message interval, so that the current message cycle 50 is divided by the basic cycle 10, and the message interval is 5. The remainder of the first sequence number 5 divided by the message interval 5 of P4 (1201) is 0, and the message offset of P4 (1201) is 0. Obviously, the remainder is the message offset of the current communication message, and the message size of the current communication message is accumulated and added to the sending flow. In this way, all communication messages are traversed to determine the sending flow.

The ratio of the current message cycle to the basic cycle is calculated as the message interval, so that the current message cycle 50 is divided by the basic cycle 10, and the message interval is 5. The remainder of the first sequence number 4 divided by the message interval 5 of P6 (1203) is 4, and the message offset of P6 (1203) is 2. Obviously, the remainder is not the message offset of the current communication message, and the message size of the current communication message is not accumulated and added to the sending flow. In this way, all communication messages are traversed to determine the sending flow.

The remainder of the second sequence number 100 divided by the message interval 5 of P4 (1201) is 0, and the message offset of P4 (1201) is 0. Obviously, the remainder is the message offset of the current communication message, and the current communication message can be encapsulated and sent.
