In a specific embodiment of the present application, the message names may be AmbCon, AT1IMG, TI1, CCVS, and the like. The CAN channel calibration amounts described above may be CAN1RX00, CAN2RX00, CAN3RX00, and the like.

It should be noted that the steps illustrated in the flowcharts of the figures 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 flowcharts, in some cases, the steps illustrated or described may be performed in an order different than here.
In order to more accurately determine the position information of the message information with the same CAN channel calibration amount in the first predetermined array, in an embodiment of the present application, determining the position information of each of the message information with the same CAN channel calibration amount in the first predetermined array according to the CAN channel calibration amount in each of the message information, so as to obtain target position information, including: comparing the CAN channel calibration quantity of each message information in the first preset array; and under the condition that the message information with the same standard quantity of at least two CAN channels exists, determining the position information of the at least two message information in the first preset array to obtain the target position information.

For example, for each message information in the first predetermined array, the CAN channel calibration amount of the first message information is compared with the CAN channel calibration amounts of all the message information located behind the first message information one by one, and the target position information of the two message information is determined under the condition that the CAN channel calibration amounts of the two message information are the same. After the comparison is completed in the current round, comparing the CAN channel calibration quantity of the second message information with the CAN channel calibration quantities of the message information behind the second message information one by one. And the rest is repeated until the comparison between the penultimate message information and the last message information in the first preset array is completed.
In order to determine target location information corresponding to each message information with the same CAN channel calibration amount more efficiently, in another embodiment of the present application, each of the message information in the first predetermined array has a first predetermined mark, and according to the CAN channel calibration amount in each of the message information, location information of each of the message information with the same CAN channel calibration amount in the first predetermined array is determined to obtain the target location information, including: comparing, namely comparing a target CAN channel standard quantity with other target CAN channel standard quantities one by one to obtain the target position information, wherein the target CAN channel standard quantity is the CAN channel standard quantity of the message information without a second preset mark; an updating step of updating the first predetermined flag of each of the message information corresponding to the target location information to the second predetermined flag according to the target location information; and repeating the comparing step and the updating step until the message information in the first preset array is completely compared.
Specifically, before comparing the CAN channel calibration amounts of the message messages in the first predetermined array, a first predetermined Flag is set for each message in the first predetermined array, for example, the first predetermined Flag = =0. And subsequently, updating the first predetermined Flag of the message information corresponding to the target position information to obtain a second predetermined Flag, for example, updating the first predetermined Flag of the message information with the same CAN channel calibration amount to the second predetermined Flag, that is, to Flag = =1, when there is the message information with the same CAN channel calibration amount.

Under the condition that the message information with the same CAN channel standard quantity exists, a preset mark CAN be added to the corresponding message information, so that the message information with the same CAN channel standard quantity CAN be distinguished from other message information. In the application, only the message information corresponding to the target position information needs to be marked, and the actual method is not limited, so that the comparison of the CAN channel standard quantity in the message information is not needed in the subsequent comparison process, and the message information with the preset mark does not need to be compared, thereby further improving the efficiency of duplicate checking.
In a specific embodiment of the present application, comparing one target CAN channel calibration amount with other target CAN channel calibration amounts one by one to obtain the target location information includes: and under the condition that the target CAN channel calibration amount is the same as the other target CAN channel calibration amounts, determining the message information corresponding to the target CAN channel calibration amount and the other target CAN channel calibration amounts as target position information according to the position information in the first preset array.
In another specific embodiment of the present application, determining, according to the CAN channel scaling amount in each of the message information, position information of each of the message information having the same CAN channel scaling amount in the first predetermined array to obtain target position information, includes: a first comparison step of comparing the CAN channel calibration amount of the ith message information with the CAN channel calibration amounts of the respective message information located after the ith message information one by one to obtain the target position information; a marking step, adding a preset mark for each message information corresponding to the target position information according to the target position information; a determining step of determining whether the (i + 1) th message information adjacent to the (i) th message information has the predetermined flag; a second comparison step of comparing the CAN channel calibration amount of the i +1 th message information with the CAN channel calibration amount of each message information which is located after the i +1 th message information and does not have the predetermined mark one by one to obtain the target position information, in a case where the i +1 th message information does not have the predetermined mark; sequentially executing the marking step, the determining step and the second comparing step at least once until all the message information in the first preset array is compared, wherein the value of i is from 1 to N-1, N is the total number of the message information in the first preset array, and i is increased by 1 during each execution; and under the condition that the (i + 1) th message information has the preset mark, sequentially executing the determining step and the second comparing step at least once until all the message information in the first preset array is compared.
In order that those skilled in the art will clearly understand the above embodiments of the present application, the following description will be given with reference to a specific embodiment. For example, there are five message messages in the first predetermined array, and the CAN channel calibration amounts of the five message messages are sequentially represented as (a, B, a, C, a), where A, B, C is not an actual representation of the CAN channel calibration amounts of the message messages. Firstly, comparing the CAN channel standard quantity of the first message information (A) with the CAN channel standard quantities of the four message information (B, A, C, A) behind the first message information one by one, so that the situation that the CAN channel standard quantities of the first message information, the third message information and the fifth message information are the same in a first preset array CAN be known, preset marks are added to the first message information, the third message information and the fifth message information, and the obtained target position information is the position information of the first message information, the third message information and the fifth message information in the first preset array. And then, determining whether the second message information (B) has a preset mark, comparing the CAN channel standard quantity of the second message information with the CAN channel standard quantity of the message information which is behind the second message information and does not have the preset mark one by one because the second message information does not have the preset mark, namely comparing the CAN channel standard quantity of the second message information (B) with the CAN channel standard quantity of the fourth message information (C), and determining the target position information by comparing the CAN channel standard quantity of the second message information with the CAN channel standard quantity of the fourth message information because the CAN channel standard quantity of the second message information is different from the CAN channel standard quantity of the fourth message information. When determining whether the third message has the predetermined mark, sequentially determining whether the fourth message has the predetermined mark because the third message has the predetermined mark, but the CAN channel calibration amount of the fourth message is not compared with the CAN channel calibration amount of the fifth message because the fifth message has the predetermined mark. The finally obtained target position information is the position information of the first message information, the third message information and the fifth message information in the first preset array.
Specifically, the CAN channel calibration amount of the i-th message is compared with the CAN channel calibration amounts of the message messages located after the i-th message one by one, for example, the CAN channel calibration amount of the first message is compared with the CAN channel calibration amount of the second message, and the CAN channel calibration amount of the first message is compared with the CAN channel calibration amount of the third message. If the CAN channel scaling amount of the first message information is the same as the CAN channel scaling amount of the second message information, determining the position information of the first message information and the second message information as the target position, and if the CAN channel scaling amount of the first message information is also the same as the CAN channel scaling amount of the third message information, determining the position information of the first message information and the third message information as the target position information, which further causes the position information of a plurality of first message information to be stored in the second predetermined array, so as to avoid repeated target position information in the subsequent second predetermined array. Determining the position information of the ith message information which is the same as the first message information and the ith message information for the first time under the condition that the CAN channel calibration amount of the ith message information is the same as the CAN channel calibration amount of one message information for the first time, and obtaining the target position information; and under the condition that the CAN channel calibration amount of the ith message information is not the same as the CAN channel calibration amount of one message information for the first time, determining the position information of the message information which is the same as the ith message information to obtain the target position information.
In another embodiment of the present application, updating the plurality of message information into the first initial predetermined array to obtain the first predetermined array includes: replacing each first preset value in the first initial preset array one by adopting each message information to obtain the first preset array; updating the target position information and the target message name to a second initial predetermined array to obtain a second predetermined array, including: and replacing each second preset value in the second initial preset array one by adopting the target position information and the target message name to obtain the second preset array, so that the first preset array and the second preset array can be obtained relatively simply.
In a specific embodiment of the application, the data type of the second predetermined array is an enumeration type.
In an embodiment of the application, after the target location information and the target packet name are updated to a second initial predetermined array to obtain a second predetermined array, the duplicate checking method further includes: storing each target position information and each target message name in the second preset array to a target text document; and sending the target text document to an upper computer. Therefore, subsequent calibration personnel can observe the repeatedly calibrated message names and the corresponding position information on the display screen of the upper computer conveniently, and the calibration personnel can modify the message names and the corresponding position information timely.
In a specific embodiment of the present application, as shown in table one, the target text document is obtained by storing the position information and the message information of each target information in the second predetermined array. Because the data type of the second predetermined array is an enumeration type, the target message names corresponding to the target position information CAN be observed in the target text document, and the target text document is subsequently sent to the upper computer, so that calibration personnel CAN further know in time that the CAN channel calibration amount corresponding to the target message names is repeatedly calibrated.

In a specific embodiment of the present application, the CAN channel scaling amounts of each message information in the first predetermined array are compared, and in order to compare the CAN channel scaling amounts of any two message information, when the CAN channel scaling amounts of two message information are the same, the position information of the two message information in the first predetermined array is determined, so as to obtain the target position information. For example, for each message information in the first predetermined array, the CAN channel calibration amount of the first message information is compared with the CAN channel calibration amounts of all the message information located behind the first message information one by one, and the target position information of the two message information is determined under the condition that the CAN channel calibration amounts of the two message information are the same.

And subsequently, updating the first predetermined Flag of the message information corresponding to the target position information to obtain a second predetermined Flag, for example, updating the first predetermined Flag of the message information with the same CAN channel calibration amount to the second predetermined Flag, that is, to Flag = =1, when there is message information with the same CAN channel calibration amount.

Under the condition that the message information with the same CAN channel standard quantity exists, a preset mark CAN be added to the corresponding message information, so that the message information with the same CAN channel standard quantity is distinguished from other message information. In the application, only the message information corresponding to the target position information needs to be marked, and the actual method is not limited, so that the comparison of the CAN channel standard quantity in the message information is not needed in the subsequent comparison process, and the message information with the preset mark does not need to be compared, thereby further improving the efficiency of duplicate checking.

Firstly, comparing the CAN channel standard quantity of the first message information (A) with the CAN channel standard quantities of the four message information (B, A, C, A) behind the first message information one by one, so that the situation that the CAN channel standard quantities of the first message information, the third message information and the fifth message information are the same in a first preset array CAN be known, preset marks are added to the first message information, the third message information and the fifth message information, and the obtained target position information is the position information of the first message information, the third message information and the fifth message information in the first preset array. And then, determining whether the second message information (B) has a preset mark, comparing the CAN channel standard quantity of the second message information with the CAN channel standard quantity of the message information which is positioned behind the second message information and does not have the preset mark one by one because the second message information does not have the preset mark, namely comparing the CAN channel standard quantity of the second message information (B) with the CAN channel standard quantity of the fourth message information (C), and determining the target position information in the round because the CAN channel standard quantity of the second message information is different from the CAN channel standard quantity of the fourth message information. When determining whether the third message has the predetermined mark, sequentially determining whether the fourth message has the predetermined mark because the third message has the predetermined mark, but not comparing the CAN channel calibration amount of the fourth message with the CAN channel calibration amount of the fifth message because the fifth message has the predetermined mark. The finally obtained target position information is the position information of the first message information, the third message information and the fifth message information in the first preset array.
Specifically, the CAN channel calibration amount of the i-th message is compared with the CAN channel calibration amounts of the message messages located after the i-th message one by one, for example, the CAN channel calibration amount of the first message is compared with the CAN channel calibration amount of the second message, and the CAN channel calibration amount of the first message is compared with the CAN channel calibration amount of the third message. If the CAN channel calibration amount of the first message information is the same as the CAN channel calibration amount of the second message information, determining the position information of the first message information and the second message information as a target position, and if the CAN channel calibration amount of the first message information is also the same as the CAN channel calibration amount of the third message information, determining the position information of the first message information and the third message information as target position information, which further causes the position information of a plurality of first message information to be stored in a second predetermined array, so as to avoid repeated target position information in a subsequent second predetermined array.

Examples
As shown in fig. 3 and 4, each message information consists of a message name 100 and a CAN channel calibration amount 101, and the first initial predetermined array is updated through each message information to obtain a first predetermined array 102 (i.e., a Port array). After the first predetermined array 102 is obtained, a first predetermined Flag is set for each message information in the first predetermined array 102, for example, the first predetermined Flag of each message information is set to Flag = =0. Then, determining the position information of each message information with the same CAN channel calibration quantity in the first preset array to obtain target position information; and updating the target position information and the target message name to a second initial preset array to obtain a second preset array.
The specific process of determining the position information of each message information with the same CAN channel calibration quantity in the first predetermined array to obtain the target position information is as follows:
as shown in fig. 4, the CAN channel calibration amount of the first message information is compared with the CAN channel calibration amounts of the message information located after the first message information one by one. Before comparing one by one, firstly, judging whether the first preset Flag [ m ] of the first message information is 0 or not. In the case where Flag [ m ] = =0 for the first message information, the CAN channel index amount of the first message information (i.e., m =0 for the first message information) is compared with the CAN channel index amount of the second message information (i.e., n = m +1=1 for the second message information) to determine whether Port [ m ] = = Port [ n ] & & Flag [ n ] = =0 is satisfied, where Port [ m ] is used for the CAN channel index amount of the mth message information, port [ n ] is used for the CAN channel index amount of the nth message information, and Flag [ n ] is used for the first predetermined Flag of the nth message information. If the above condition is not satisfied, n is sequentially incremented by 1 (i.e., n + +, as shown in fig. 4), that is, the first message information is compared with the third message information again. When the above condition is satisfied, the location information index [ m ] of Port [ m ] and the location information index [ n ] of Port [ n ] are recorded, that is, the location information of the first packet information and the second packet information in the first predetermined array is recorded, so as to obtain the target location information. Because the CAN channel calibration amount of the first message information is the same as that of the second message information, both Flag [ m ] and Flag [ n ] are set to 1, that is, the predetermined Flag of the first message information and the first predetermined Flag of the second message information are updated to obtain the second predetermined Flag. And then, judging whether N is larger than N again, wherein N is the total amount of the message information in the first preset array. And under the condition that N is less than or equal to N, the CAN channel calibration quantity of the first message information is not compared with the CAN channel calibration quantity behind the first message information one by one, so that the current N is gradually increased by 1 and is compared again. If N is larger than N, the CAN channel calibration quantity of the first message information is compared with the CAN channel calibration quantity behind the first message information one by one. Thereafter, m is gradually increased by 1 (i.e., m + +, shown in FIG. 4), and it is determined whether m is smaller than N. In the case where m is smaller than N, since the predetermined Flag of the message information has been updated before, it needs to be determined again whether the predetermined Flag of the second message information satisfies Flag [ m ] = =0. If the comparison result is satisfied, the CAN channel scaling quantity of the second packet information is compared with the CAN channel scaling quantity of the respective packet information that follows the second packet information and that does not have the predefined Flag = =0, i.e., it is determined again whether Port [ m ] = = Port [ n ] & & Flag [ n ] = =0 is satisfied, until the packet information in the first predefined array is compared completely, and the second predefined array is output.
