[0040] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0041] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The main solution of the embodiment of the present application is: parsing the data acquisition instruction to obtain the ID code of the electronic controller unit ECU, the DID code of the acquisition signal, the acquisition duration and the acquisition frequency; based on the DID code, the acquisition frequency and the acquisition duration, the ECU performs data acquisition to obtain the first acquisition data; analyzing the first acquisition data to obtain the acquisition rule, and based on the acquisition rule, the ECU performs data acquisition to obtain the second acquisition data. The ECU analyzes the DID code to obtain the acquisition signal value, and creates a data storage area based on the acquisition signal value; according to the acquisition frequency, the ECU performs data acquisition on the signal source corresponding to the acquisition signal value; when the acquisition duration is reached, the data acquisition is stopped to obtain the first acquisition data, and the first acquisition data is stored in the data storage area. The first acquisition data is analyzed to obtain data segmentation and segmentation value; based on the data segmentation and segmentation value, the acquisition rule is constructed; based on the acquisition rule, the ECU performs data acquisition on the signal source to obtain the second acquisition data. A data acquisition instruction is sent to the vehicle end, and the vehicle end performs data acquisition based on the data acquisition instruction to obtain a data acquisition result, wherein the data acquisition result includes first acquisition data, second acquisition data and acquisition rules; the data acquisition result sent by the vehicle end is received, and the second acquisition data is verified based on the first acquisition data and the acquisition rules to obtain transmission data. The acquisition rules are analyzed based on the first acquisition data to obtain data segmentation and segmentation value; the second acquisition data is data verified by the data segmentation and segmentation value to obtain a verification result; when the verification result is passed, the transmission data is obtained. Thus, the problem of ECU data interaction delay caused by large data transmission volume is solved, data transmission is realized, and the efficiency of data transmission is improved. Based on the scheme of the present invention, when the acquisition frequency is high and the time is long, there will be a large number of requests and replies. The vehicle bus is shared by all ECUs, which will cause a large amount of data transmission on the bus, which may cause delays in data interaction between each ECU, thereby inefficient. A data transmission method is designed, and the effectiveness of the data transmission method of the present invention is verified when data is transmitted. Finally, the efficiency of data transmission through the method of the present invention is significantly improved.

[0043] In this embodiment, for the convenience of description, the following description is made with the data transmission device as the execution subject.

[0044] In the prior art, when analyzing vehicle faults, it is necessary to collect vehicle data at certain intervals and determine the cause of the fault through changes in the data. For example, if the sensor value is collected once every 50 ms, then data needs to be collected 200 times in 10 minutes, and the collection device needs to communicate and interact with the ECU 200 times. This will cause excessive data transmission on the vehicle bus, which may cause transmission delays and affect the information interaction of each ECU on the bus.

[0045] The present application provides a solution. Since most ECU data change linearly and regularly, when collecting linearly changing data, the ECU can be specified to perform temporary storage and regular statistics inside the ECU according to the set frequency and collection duration. When the data collection is completed, only the segmentation mark data in the data change rule needs to be replied to the collection device. The collection device can calculate the data at other time points through these mark data. In this way, the data transmission volume of the vehicle bus during data collection can be greatly reduced, the bus load rate can be reduced, and the communication efficiency of each ECU on the vehicle bus will not be affected.

[0046] From the above embodiments, it can be seen that the present application receives user questions; analyzes the user questions to obtain key information, and matches the pre-built intention slot based on the key information to obtain a matching slot; confirms the intention of the user questions according to the matching slot to obtain data transmission results. Thus, corresponding data collection is performed when the data collection instruction of the data collection device is received, and data is synchronously extracted during the collection process for rule analysis to obtain corresponding data collection rules. When data is subsequently collected, data is collected according to the data collection rules, so that the amount of data subsequently transmitted becomes smaller, and the first collected data, the second collected data and the data collection rules are all sent to the data collection device so that the data collection device verifies the data, ensuring the accuracy of the data, solving the problem of ECU data interaction delay caused by large data transmission volume, and improving the efficiency of data transmission.

[0047] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, an intention device device, etc. that can realize the above functions. The following takes a data transmission device as an example to illustrate this embodiment and the following embodiments.

[0048] Based on this, the embodiment of the present application provides a data transmission method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the data transmission method of the present application.

[0049] In this embodiment, the data transmission method is applied to the vehicle side, and the method includes steps S01 to S02:

[0050] Step S01, receiving a data collection instruction sent by a data collection device, and performing data collection based on the data collection instruction to obtain a data collection result, wherein the data collection result includes first collection data, second collection data and a data collection rule;

[0051] It should be clear that ECU (Electronic Control Unit), also known as the car's "on-board computer", is used to control the car's driving status and realize its various functions. It mainly uses various sensors and bus data collection and exchange to judge the vehicle status and the driver's intention and control the car through actuators. Currently, vehicles are equipped with multiple ECUs, such as engine ECU, gearbox ECU, etc. When the collection frequency is high and the time is long, the ECU will have a large number of requests and replies. The vehicle bus is shared by all ECUs, which will cause a large amount of data transmission on the bus, which may cause delays in data interaction between ECUs.

[0052] Therefore, the vehicle end in this embodiment receives the data collection instruction sent from the data collection device, and performs data collection based on the data collection instruction to obtain the data collection result. It should be clear that the data collection result includes at least the first collected data, the second collected data and the data collection rules, among which the first collected data can be understood as the specific collected data, and the data collection rules are obtained by analyzing the first collected data. It can clearly know the rules in the collected data, and then the subsequent data can be collected based on the data collection rules to obtain the second collected data with incomplete data volume but regularity.

[0053] Step S02: sending the data collection result to the data collection device, and the data collection device verifies the second collected data based on the first collected data and data collection rules to obtain transmission data.

[0054] After obtaining the data collection results, they can be sent to the data collection device, which verifies the second collected data based on the first collected data and the data collection rules to obtain specific transmission data. In the above embodiment, it has been explained that the second collected data is collected based on the data collection rules, so the data collection rules and the first collected data can be used for verification. After confirming the correctness of the data collection rules, the second collected data is analyzed and verified through the data collection rules to obtain the final transmission data.

[0055] Specifically, the above step S01, the step of performing data collection based on the data collection instruction to obtain the data collection result includes:

[0056] Step S011, parsing the data acquisition instruction to obtain the ID code of the electronic controller unit ECU, the DID code of the acquisition signal, the acquisition duration and the acquisition frequency;

[0057] Step S012, based on the DID code, the acquisition frequency and the acquisition duration, data is acquired through the ECU to obtain first acquired data;

[0058] Step S013: Analyze the first collected data to obtain a data collection rule, and based on the data collection rule, collect data through the ECU to obtain second collected data.

[0059] After receiving the data collection instruction, it is parsed to obtain the ID code of the electronic controller unit ECU for data collection, the DID code of the collection signal (data source), the collection duration and the collection frequency. The decentralized identity identifier (DID) is a new type of identity recognition standard that aims to allow individuals and entities to own and control their identity information without relying on a centralized identity provider.

[0060] Then, based on the DID code, the collection frequency and the collection duration, the corresponding ECU is controlled by the identity identifier ID code to collect data, and the first collected data is obtained;

[0061] In order to avoid excessive data collection and resulting in inefficient transmission, in this embodiment, the first collected data is analyzed to obtain a data collection rule, and subsequent data collection is performed based on the data collection rule to obtain the second collected data.

[0062] More specifically, in the above step S012, based on the DID code, the acquisition frequency and the acquisition duration, the step of acquiring the first acquisition data by the ECU includes:

[0063] Step S0121, analyzing the DID code by the ECU to obtain a collection signal value, and creating a data storage area based on the collection signal value;

[0064] Step S0122, collecting data on a signal source corresponding to the collected signal value through the ECU according to the collection frequency;

[0065] Step S0123, when the collection time is reached, stop data collection, obtain first collected data, and store the first collected data in the data storage area.

[0066] In order to collect data through the ECU, the signal source for collection must be known first. Therefore, in this embodiment, the ECU analyzes the DID code to obtain the collected signal value and simultaneously creates a data storage area;

[0067] In this embodiment, the engine ECU is taken as an example. The DID is 0x8001, which represents the speed signal value. The total acquisition time is 600s, and the acquisition frequency is 50ms. After the engine ECU receives it, a data storage area will be temporarily opened inside the ECU. The value of the signal to be read will be determined based on the DID, and then the speed data will be saved in the data storage area once every 50ms at the acquisition frequency until the total time of 600s is reached. At this time, the data obtained is the first acquisition data.

[0068] Furthermore, in the above step S013, the step of analyzing the first collected data to obtain a data collection rule, and based on the data collection rule, collecting data through the ECU to obtain the second collected data includes:

[0069] Step S0131, analyzing the first collected data to obtain data segments and segment values;

[0070] Step S0132, constructing data collection rules based on the data segments and segment values;

[0071] Step S0133: Based on the data collection rule, the ECU collects data from the signal source to obtain second collected data.

[0072] After the total time is reached, the engine ECU does not need to reply all the stored data to the data acquisition device because there is too much data. Rules can be summarized based on the collected data, because the changes in linear data are regular, and only the time and value of each segment point need to be replied to the data acquisition device. In this embodiment, the collected values ​​are as follows: Figure 2 As shown, (time1, value1), (time2, value2), (time3, value3), (time4, value4), (time5, value5) represent the relationship between data segments and segment values. For linear data, this has observable regularity, and the data collection rules can be constructed through data segments (time) and segment values ​​(value, value).

[0073] Then, when collecting data, it is no longer necessary to obtain all the data, but rather to obtain data with regularity to obtain the second collected data.

[0074] This embodiment adopts the above scheme, specifically by receiving the data acquisition instruction sent by the data acquisition device, performing data acquisition based on the data acquisition instruction to obtain the data acquisition result, the data acquisition result includes the first acquisition data, the second acquisition data and the acquisition rule; the data acquisition result is sent to the data acquisition device, and the data acquisition device verifies the second acquisition data based on the first acquisition data and the acquisition rule to obtain the transmission data. Thus, when the data acquisition instruction of the data acquisition device is received, the corresponding data acquisition is performed, and during the acquisition process, the data is synchronously extracted for rule analysis to obtain the corresponding acquisition rule, and the data acquisition is performed according to the acquisition rule when the data is subsequently acquired, so that the amount of data subsequently transmitted becomes smaller, and the first acquisition data, the second acquisition data and the acquisition rule are all sent to the data acquisition device, so that the data acquisition device verifies the data, ensures the accuracy of the data, solves the problem of ECU data interaction delay caused by large data transmission volume, and improves the efficiency of data transmission.

[0075] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 The data transmission method is also applied to data acquisition equipment, and the method includes steps S03 to S04:

[0076] Step S03, sending a data collection instruction to the vehicle end, and the vehicle end performs data collection based on the data collection instruction to obtain a data collection result, wherein the data collection result includes first collected data, second collected data and data collection rules;

[0077] Step S04, receiving the data collection result sent by the vehicle end, verifying the second collected data based on the first collected data and data collection rules, and obtaining transmission data.

[0078] This embodiment provides a specific solution of a data acquisition device. In this embodiment, the data acquisition device can be a diagnostic device for performing vehicle diagnosis. When the vehicle engine is detected, the data acquisition device can send a data acquisition instruction to the vehicle end. The vehicle end performs data acquisition based on the data acquisition instruction to obtain a data acquisition result, and sends the data acquisition result back to the data acquisition device.

[0079] It is clear in the above embodiments that the data collection results include the first collected data, the second collected data and the collection rules. Therefore, after receiving the data collection results sent back by the vehicle end, the second collected data can be verified by the first collected data and the collection rules to obtain the transmission data. It should be clear that the final transmission data can be obtained by splicing the first collected data after verifying the second collected data, and the specific setting should be based on actual business needs.

[0080] Specifically, the above step S04, receiving the data collection result sent by the vehicle end, and calculating the second collected data based on the first collected data and the data collection rule to obtain the final data collection result, includes:

[0081] Step S041, analyzing the data collection rule based on the first collected data to obtain data segments and segment values;

[0082] Step S042, performing data verification on the second collected data through the data segmentation and segmentation value to obtain a verification result;

[0083] Step S043, when the verification result is passed, obtain the transmission data.

[0084] After the data acquisition device receives the time and value of each segmentation point replied by the engine ECU, the value corresponding to any time point can be calculated by an algorithm. For example, to calculate the value of time point timeX, first determine that the segmentation points before and after timeX are (time3, value3) and (time4, value4), respectively. Then, according to the calculation formula valueX=value3+(value4-value3) / (time4-time3)*(timeX-time3), the value of the second collected data can be obtained. In order to verify whether the result is correct, in this embodiment, the data acquisition rules are analyzed based on the first collected data to obtain data segmentation and segmentation values, and whether the data acquisition rules are reasonable are judged. Subsequently, data verification is performed on the second collected data through data segmentation and segmentation values ​​to verify whether the second collected data complies with the data acquisition rules. If the verification is passed, the transmission data can be output based on the second collected data alone, or the first collected data and the second collected data can be combined to obtain the transmission data.

[0085] This embodiment uses the above scheme, specifically by sending a data collection instruction to the vehicle end, and the vehicle end performs data collection based on the data collection instruction to obtain a data collection result, and the data collection result includes the first collection data, the second collection data and the collection rule; the data collection result sent by the vehicle end is received, and the second collection data is verified based on the first collection data and the collection rule to obtain the transmission data. Therefore, when the data collection instruction of the collection device is received, the corresponding data collection is performed, and during the collection process, the data is synchronously extracted for rule analysis to obtain the corresponding collection rule, and the data is collected according to the collection rule when the data is subsequently collected, so that the amount of data subsequently transmitted becomes smaller, and the first collection data, the second collection data and the collection rule are all sent to the collection device, so that the collection device verifies the data, ensures the accuracy of the data, solves the problem of ECU data interaction delay caused by large data transmission volume, and improves the efficiency of data transmission.

[0086] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the data transmission method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
