[0033] In this embodiment, a method for processing repeated configuration of a message channel running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] Figure 2 1 is a flowchart of a method for processing repeated message channel configuration according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0035] Step S201, after the ECU upgrades the program, obtain the message names of all types of messages of the ECU;

[0036] Step S202, according to the message channel configuration result, the corresponding message channels are marked in sequence with each of the message names, wherein the message channel configuration result is the correspondence between the message names and the message channels;

[0037] Step S203, when multiple message channels are marked with the same message name or one message channel is marked with multiple message names, reconfigure the message channel so that one message name corresponds to one message channel and one message channel corresponds to one message name.

[0038] In the above-mentioned method for processing repeated message channel configuration, after the ECU upgrade program, the corresponding message channels are marked in sequence with each message name according to the message channel configuration result. If the message name corresponds to the message channel one-to-one, there is no configuration duplication. If multiple message channels are marked with the same message name or one message channel is marked with multiple message names, it indicates that the configuration is repeated. The message channel configuration is re-performed to ensure that one of the above-mentioned message names corresponds to one of the above-mentioned message channels and one of the above-mentioned message channels corresponds to one of the above-mentioned message names. This can solve the problem of repeated message channel configuration and solve the problem of large workload of manually checking the problem of repeated message channel configuration in the prior art.

[0039] In order to avoid repeated marking, in an optional implementation manner, the above step S202 includes:

[0040] Step S2021, numbering each of the above message names to obtain a number for each of the above message names;

[0041] Step S2022: in the order of the numbers, the message channels corresponding to the message names in the message channel configuration result are marked in sequence using the message names corresponding to the numbers.

[0042] In the above implementation, all message names are defined as different keywords 1, keyword 2, ... keyword N, and the message channels corresponding to the message names in the message channel configuration results are marked in sequence according to the order of keywords 1-N.

[0043] In order to check whether a message is configured with multiple message channels, in an optional implementation, before reconfiguring the message channels so that one of the message channels corresponds to one of the message channels and one of the message channels corresponds to one of the message channels, the method further includes:

[0044] Step S301, recording the number of times each of the message names is marked to obtain a plurality of marking times, wherein the marking times correspond to the message names one by one;

[0045] Step S302: when any of the marking times is greater than or equal to 2, determine the message names of the plurality of message channel marks that have the same mark.

[0046] In the above implementation, when a message is configured with multiple message channels, the message name will be marked multiple times according to the corresponding relationship in the message channel configuration result, and the number of times each message name is marked is recorded to obtain multiple marking times. Any of the above marking times is greater than or equal to 2, indicating that a message is configured with multiple message channels, thereby resulting in the presence of multiple message names with the same message channel mark.

[0047] In order to check for duplication of message channel configuration, in an optional implementation, as Figure 3 As shown, before reconfiguring the message channel so that one of the message channels corresponds to one of the message channels and one of the message channels corresponds to one of the message channels, the method further includes:

[0048] Step S401, obtaining the number of the message names marked by each of the message channels, and obtaining a plurality of message name numbers, wherein the message name numbers correspond one-to-one to the message channels;

[0049] Step S402: when the number of any of the message names is greater than or equal to 2, determine one of the message channels to mark multiple message names.

[0050] In the above implementation, the number of the above-mentioned message names marked by each of the above-mentioned message channels is obtained, and the number of multiple message names is obtained, so that it can be determined that a message channel is configured with several types of messages. If any number of the above-mentioned message names is greater than or equal to 2, it indicates that the message channel is configured with multiple messages and belongs to a repeated channel, so that one message channel is marked with multiple message names.

[0051] In order to avoid message communication failure, in an optional implementation, as Figure 4 As shown, in the case where the number of any of the message names is greater than or equal to 2, after determining that one of the message channels marks a plurality of the message names, the method further includes:

[0052] Step S501, determining the message channels corresponding to the number of message names greater than or equal to 2 as duplicate channels;

[0053] Step S502, issuing an alarm message and displaying the above-mentioned repeated channels.

[0054] In the above implementation, since duplicate configuration of the message channel may cause the message to fail to be received and sent normally, the duplicate channel is detected and an alarm is displayed to facilitate timely maintenance and avoid communication failures.

[0055] In order to ensure normal message sending and receiving, in an optional implementation manner, the above step S203 includes:

[0056] Step S2031, in the case where the same message name is marked on a plurality of the message channels, the message name of one of the plurality of the message channels with the same message name is retained, and the message names of the other message channels are deleted;

[0057] Step S2032, when a plurality of message names are marked on one message channel, the message channel only retains one message name and marks the other message names as unconfigured channels;

[0058] Step S2033: forward the message contents of the message names of the unconfigured channels in sequence to the message channels that are not marked with the message names.

[0059] In the above implementation manner, when multiple message channels are marked with the same message name, the message name of one message channel is retained, so that the message name only marks one message channel, and the channel addresses of other message channels are marked as unused, and messages corresponding to other message names can also be configured; when one message channel is marked with multiple message names, the message channel only retains one message name, and the other message names are marked as unconfigured channels, and the message channel needs to be reconfigured, and the message contents of the message names of the unconfigured channels are forwarded in sequence to the message channels that are not marked with the message names, so as to avoid channel duplication and ensure normal message sending and receiving.

[0060] In order to ensure that one message channel is configured with one message, in an optional implementation, the above step S2033 includes:

[0061] Step S20331, obtaining the number of the message names marked by each of the message channels, and obtaining a plurality of message name numbers, wherein the message name numbers correspond one-to-one to the message channels;

[0062] Step S20332, determining the message channels corresponding to the number of message names greater than or equal to 2 as duplicate channels;

[0063] Step S20333, sorting the channel addresses of the plurality of repeated channels to obtain a first channel address sequence;

[0064] Step S20334, sorting the channel addresses of the message channels marked as unconfigured channels to obtain a second channel address sequence;

[0065] Step S20335: forward the message content on the channel address of the first channel address sequence to the corresponding channel address of the second channel address sequence, and the channel address of the first channel address sequence corresponds to the channel address of the second channel address sequence one by one.

[0066] In the above implementation, repeated channels are screened out, the channel addresses of the multiple repeated channels are sorted to obtain a first channel address sequence, and the channel addresses of the multiple message channels marked as unconfigured channels are sorted to obtain a second channel address sequence, and the message contents on the channel addresses of the first channel address sequence are forwarded to the channel addresses of the second channel address sequence one by one. For example, the K channel addresses of all repeated channels are sorted as D1, D2...DK and the L channel addresses of the unconfigured channels are sorted as d1, d2, d3...dL, and the message contents on the repeated channel addresses are forwarded to the channel addresses of the unconfigured channels D1->d1, D2->d2... in sequence for message sending and receiving.

[0067] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for processing repeated message channel configuration of the present application will be described in detail below in conjunction with specific embodiments.

[0068] This embodiment relates to a specific method for processing repeated message channel configurations, such as Figure 5 As shown, the following steps are included:

[0069] There are generally two communication CANs on the current vehicle CAN network, the first communication CAN and the second communication CAN. First, determine whether the message in the software is correctly configured on the first communication CAN or the second communication CAN. If so, check the message configuration on each communication CAN to see if there is a duplicate channel configuration; if there is an error in the message configuration of the first communication CAN and the second communication CAN, filter out the incorrectly configured messages and channels, correctly assign the messages to the first or second communication CAN, and process them together with the messages of the duplicately configured channels checked on the corresponding first communication CAN or second communication CAN.

[0070] The message channel checking method for the first CAN communication and the second CAN communication is as follows: define all message names as different keywords 1, keyword 2, ... keyword N, establish a database, take all channel address information into the database, and check the correspondence between all keywords and the information in the database according to a certain mapping relationship. Define two counters T and t, counter T is a counter for multiple keywords corresponding to one database information, and counter t is a counter for one keyword corresponding to multiple database information. Traverse all keywords and database information. If a keyword corresponds to n database information, counter t=n, n>=2, it means that a message is configured with multiple channels. At this time, the database information mapped to the first keyword is retained, and the remaining database information is marked as unused; if m keywords correspond to one database information, counter T=m, m>=2, it means that the channel configuration is repeated. At this time, the keyword mapped to the first database information is retained, and the remaining keyword information is marked as unconfigured channels, waiting for subsequent reconfiguration of channels. After traversing all keywords and database information, the values ​​of counters T and t are output and an alarm is displayed. If after checking the mapping of all keywords and the database, channels are repeated, the repeated channels are screened out, and the K channel addresses of all repeated channels are recorded and sorted as D1, D2...DK, and the L channel addresses of unconfigured channels are sorted as d1, d2, d3...dL, and the message content on the repeated channel address is forwarded to the channel address of the unconfigured channel D1->d1, D2->d2... in sequence for message sending and receiving.

[0071] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0072] The embodiment of the present application also provides a kind of processing device of message channel configuration duplication, it should be noted that the processing device of message channel configuration duplication of the embodiment of the present application can be used to execute the processing method for message channel configuration duplication provided by the embodiment of the present application. The device is used to implement the above-mentioned embodiment and preferred implementation mode, and the description has been made no more. As used below, the term "module" can implement the combination of software and / or hardware of the predetermined function. Although the device described in the following embodiments is preferably implemented with software, the implementation of hardware, or the combination of software and hardware is also possible and conceived.

[0073] The following introduces a device for processing repeated message channel configurations provided in an embodiment of the present application.

[0077] The configuration unit 30 is used to reconfigure the message channel when multiple message channels are marked with the same message name or one message channel is marked with multiple message names, so that one message name corresponds to one message channel and one message channel corresponds to one message name.

[0078] In the above-mentioned processing device for repeated message channel configuration, after the ECU upgrade program, the corresponding message channels are marked in sequence with each message name according to the message channel configuration result. If the message name corresponds to the message channel one-to-one, there is no configuration duplication. If multiple message channels are marked with the same message name or one message channel is marked with multiple message names, it indicates that the configuration is repeated. The message channel configuration is re-performed to ensure that one of the above-mentioned message names corresponds to one of the above-mentioned message channels and one of the above-mentioned message channels corresponds to one of the above-mentioned message names. This can solve the problem of repeated message channel configuration and solve the problem of large workload of manually checking the problem of repeated message channel configuration in the prior art.

[0084] A first recording unit is used to record the number of times each of the message names is marked before reconfiguring the message channels so that one of the message channels corresponds to one of the message channels and one of the message channels corresponds to one of the message channels, to obtain a plurality of marking times, wherein the marking times correspond to the message names one by one;

[0085] The first determining unit is used to determine the message names having the same message channel mark when any of the marking times is greater than or equal to 2.

[0086] In the above implementation, when a message is configured with multiple message channels, the message name will be marked multiple times according to the corresponding relationship in the message channel configuration result, and the number of times each message name is marked is recorded to obtain multiple marking times. Any of the above marking times is greater than or equal to 2, indicating that a message is configured with multiple message channels, thereby resulting in the presence of multiple message names with the same message channel mark.

[0087] In order to check for duplication of message channel configuration, in an optional implementation, as Figure 3 As shown, the above device also includes:

[0088] A second recording unit is used to obtain the number of the message names marked by each of the message channels before reconfiguring the message channels so that one of the message channels corresponds to one of the message channels and one of the message channels corresponds to one of the message channels, so as to obtain a plurality of message name numbers, wherein the message name numbers correspond to the message channels one by one;

[0089] The second determining unit is used to determine that one of the message channels marks multiple message names when the number of any of the message names is greater than or equal to 2.

[0090] In the above implementation, the number of the above-mentioned message names marked by each of the above-mentioned message channels is obtained, and the number of multiple message names is obtained, so that it can be determined that a message channel is configured with several types of messages. If any number of the above-mentioned message names is greater than or equal to 2, it indicates that the message channel is configured with multiple messages and belongs to a repeated channel, so that one message channel is marked with multiple message names.

[0091] In order to avoid message communication failure, in an optional implementation, as Figure 4 As shown, the above device also includes:

[0093] The alarm unit is used to issue an alarm message and display the above-mentioned repeated channels.

[0094] In the above implementation, since duplicate configuration of the message channel may cause the message to fail to be received and sent normally, the duplicate channel is detected and an alarm is displayed to facilitate timely maintenance and avoid communication failures.

[0095] In order to ensure normal message sending and receiving, in an optional implementation manner, the above configuration unit includes:

[0097] A second processing module is used for, when a plurality of message names are marked on one message channel, retaining only one message name on the message channel and marking the other message names as unconfigured channels;

[0098] The forwarding module is used to sequentially forward the message contents of the message names of the unconfigured channels to the message channels that are not marked with the message names.
