[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] At present, some diagnostic software usually puts the configuration file on the server, downloads it when needed, and calls it to display the corresponding data stream when the data stream is running. However, the downloaded file is essentially an offline file, which is easy to be cracked and occupied by other companies. The downloaded file contains a lot of information. Once downloaded by others, all the configuration information of the entire ECU data stream will be leaked. To this end, the present application provides an online data stream display method. The target server side calculates the value of the data stream based on the command reply information corresponding to the data stream command and uses the preset data stream algorithm in the database. It can effectively realize the diagnostic software data stream that cannot be reverse cracked, prevent the occurrence of piracy and reverse engineering, and thus ensure the security of data stream information.

[0049] See also Figure 1 As shown, an embodiment of the present invention discloses an online data stream display method, including:

[0050] Step S11: sending the key information of the target vehicle model to the target server end with which a communication connection has been established in advance through a preset data transmission method, so that the target server end obtains corresponding data stream information from a database based on the received key information.

[0051] In this embodiment, before sending the key information of the target vehicle model to the target server end with which the communication connection has been pre-established through the preset data transmission method, the target server and the client end need to pre-establish a communication connection. Specifically, before sending the key information of the target vehicle model to the target server end with which the communication connection has been pre-established through the preset data transmission method, it also includes: after entering the data stream corresponding to the target vehicle model through the installed preset diagnostic tool, a connection request is initiated to the target server end based on the data stream and the preset full-duplex communication protocol, so that the target server end establishes a communication connection with the client end with the installed preset diagnostic tool based on the connection request.

[0052] It is understandable that after the target server establishes a communication connection with the client, the client sends the key information of the target vehicle model to the target server. Specifically, the key information of the target vehicle model is sent to the target server with which the communication connection has been established in advance through the preset data transmission method, including: sending the key information including the identity information, software version information, configuration information and electronic system configuration information of the target vehicle model to the target server with which the communication connection has been established in advance through the preset data transmission method, the preset full-duplex communication protocol and the first preset information transmission format.

[0053] In a specific implementation, the client and the target server are connected via WebSocket (a full-duplex communication protocol) for bidirectional data transmission. The client can send data to communicate with the target server via the WebSocket object. Similarly, when the target server sends a message to the client, the client triggers a preset data transmission event of the WebSocket object, thereby obtaining the data sent by the target server. When you want to close the connection, you can close the connection by calling the close() method of the WebSocket object.

[0054] In another specific implementation, after entering the data stream corresponding to the target vehicle model through the installed preset diagnostic tool, the client can initiate an HTTP request including additional HTTP (Hypertext Transfer Protocol) header information to the target server, wherein the additional HTTP header information can be a connection request for applying to upgrade the current HTTP protocol to the WebSocket protocol. If the target server can correctly interpret the additional HTTP header information, it indicates that the target server can understand and accept the upgrade of the current HTTP protocol to the WebSocket protocol. After the client obtains the upgrade response returned by the target server and confirms that the handshake information of the target server is correct, a WebSocket communication connection is established. During the handshake process, the target server returns an HTTP-based response message to the client. After receiving the response message, if the client verifies that the response message information is correct, the client and the target server can communicate through the WebSocket protocol. It should be pointed out that the client and the target server can establish a communication connection based on a protocol that meets actual needs, which is not specifically limited here.

[0055] In this embodiment, the first preset information transmission format can be serial transmission, and the identity identification information, software version information, configuration information and electronic system configuration information of the target vehicle model are transmitted in bit order, that is, they are sent one bit after another; the first preset information transmission format can also be parallel transmission, that is, multiple bits of data are sent at the same time, and the identity identification information, software version information, configuration information and electronic system configuration information of the target vehicle model are transmitted through multiple data lines. The preset information transmission format can be selected according to actual needs and is not specifically limited here.

[0056] It is understandable that the key information of the target vehicle model may need to be converted into a specific vehicle model data format, so that after the target server receives the key information in the specific vehicle model data format, it can obtain data stream information corresponding to the key information from the database based on the key information. In a specific implementation, the key information code of the target vehicle model is as follows:

[0057] {

[0058] "sn": "911111",

[0059] "version": "V34.20",

[0060] "vin": "11111111111111111",

[0061] "ecuId": "51224235"

[0062] }

[0063] Among them, the key information of the target vehicle model includes but is not limited to the device information sn (serial number), version, vehicle model vin (vehicle identification number) code of the target vehicle model and the ECU number corresponding to the target vehicle model (that is, "ecuId" in the aforementioned code). The key information of the corresponding target vehicle model can be determined according to actual needs and is not specifically limited here.

[0064] It can be understood that after the target server obtains the key information of the target vehicle model sent by the client, it obtains the data stream information corresponding to the key information from the database based on the key information. In a specific implementation, the code of the data stream information is as follows:

[0065] {

[0066] "data": {

[0067] "01": {

[0068] "group": "TYPE1",

[0069] "name": "vehicle speed",

[0070] "unit": "km / h",

[0071] "cmd": "03 22 F1 36"

[0072] },

[0073] "02": {

[0074] "group": "TYPE2",

[0075] "name": "Oil Temperature",

[0076] "unit": "Celsius",

[0077] "cmd": "03 22 F1 37"

[0078] }

[0079] }

[0080] }

[0081] The data field contains the data stream numbers 01 and 02, the group field is used to display the data stream group, name is the data stream command, unit is the unit of the data stream, and cmd is the data of the command sent. It should be pointed out that any information that can represent the current data of the target vehicle model can be used as data stream information, and will not be repeated here.

[0082] Step S12: After receiving the data flow information sent by the target server, execute a command based on the data flow command information in the data flow information to obtain corresponding command reply information.

[0083] In this embodiment, after receiving the data stream information sent by the target server, the data stream command information in the data stream information is executed to obtain different command reply information corresponding to the data stream command information. Specifically, after receiving the data stream information sent by the target server, the data stream command information in the data stream information is executed to obtain the corresponding command reply information, including: obtaining the data stream information including the data stream command information sent by the target server, and executing the data stream command information; in the process of executing the command, for the first data stream command that has been responded to normally, determining the first command reply information corresponding to the first data stream command based on the corresponding response result; wherein the first command reply information includes the corresponding character string information that satisfies the preset data system; for the second data stream command that has been negatively responded and does not have response information, determining the second command reply information corresponding to the second data stream command that represents the empty set; determining the corresponding command reply information based on the first command reply information, the second command reply information and the second preset information transmission format.

[0084] It can be understood that if there is corresponding command reply information after the data stream command is executed, in a specific implementation, for the 01 data stream, if the data stream command responds normally after execution, the corresponding command reply information is obtained, and the command reply information can be a hexadecimal string or other strings that can represent the data stream command information; and for the 02 data stream, if the data stream command has no reply or a 7F negative response (Negative Response), then its value is empty at this time, and the relevant code is as follows:

[0085] {

[0086] "data": [

[0087] "01": "62 F1 36 01 02 03",

[0088] "02": "-" ]

[0090] }

[0091] In a specific implementation, the negative response code (NRC) is a code used to indicate the specific reason for the negative response. For example, when NRC is 0x22, the negative response message should be accompanied by a specific cause code (i.e., Specific Cause Code). 0x00 is usually used to implement the negative response code judgment logic to indicate that a positive response is to be given, while 0x01 to 0x7F are negative response codes related to diagnostic communication, and 0x80 to 0xFF are negative response codes given due to certain conditions not meeting the requirements.

[0092] Step S13: sending the command reply information to the target server based on a preset data upload method, so that the target server determines corresponding data flow value information based on the command reply information and through a preset data flow algorithm in the database.

[0093] In this embodiment, after the target server receives the command reply information uploaded by the client based on the preset data upload method, the command reply information is calculated by the preset data flow algorithm configured in the database of the target server to obtain the data flow value information corresponding to the command reply information. Wherein, the preset data upload method can be OBS Browser+ (Object Storage Service, i.e., access and management of object storage services). If the size of the command reply information is less than 500GB, OBS Browser+ can be used to send the command reply information to the target server; if the size of the command reply information is greater than 500GB, the command line tool OBSUtil (Object Storage Service Utility, i.e., object storage service tool) can be used. The command line tool obsutil can not only upload file information with a large data volume (file size exceeds 500GB), but also perform batch processing and automation tasks as needed, and supports the use of the three major platforms of Windows, Linux, and macOS; if the command reply information needs to be transmitted in time, data express can be used to send the command reply information to the server. Data express provides a fast and efficient data upload method that can ensure the timeliness of data transmission. It should be pointed out that the data upload method should be selected according to the specific situation and actual needs, and is not limited here.

[0094] In this embodiment, the preset data flow algorithms in the database of the target server side include but are not limited to data-driven methods and demand-driven methods, wherein the data-driven method triggers the calculation operation based on the command reply information received by the target server side, while the demand-driven method is based on obtaining the corresponding data flow value information, thereby triggering the calculation operation of the command reply information through the preset data flow algorithm in the database. These two methods are suitable for different data processing needs. Which algorithm to choose depends on the specific situation and is not specifically limited here.

[0095] Step S14: after receiving the data stream value information sent by the target server, use the data stream value information and the data stream information to complete the online data stream display operation corresponding to the target vehicle model.

[0096] In this embodiment, the data flow value information and the data flow information are displayed, so that the working status information of various electronic systems and actuators in the target vehicle model can be understood in real time. In a specific implementation manner, the client receives the data flow value information code sent by the target server as follows:

[0097] {

[0098] "data": [

[0099] "01": "value": "25.6",

[0100] "02": "value": "-" ]

[0102] }

[0103] Among them, 01 and 02 correspond to the numbers of the data flow command information in the data flow information. The data flow value information obtained at this time is a specific numerical value. Since the command reply information of the data flow command information corresponding to 02 is an empty set, the 02 data flow value information finally calculated based on the command reply information is also an empty set.

[0104] It can be understood that after receiving the data stream value information sent by the target server, the data stream value information and the data stream information are used to complete the online data stream display operation corresponding to the target vehicle model, including: after receiving the data stream value information sent by the target server based on the third preset transmission format, based on the data stream value information and the data stream name information and data stream unit information in the data stream information and through a preset display interface, the online data stream display operation corresponding to the target vehicle model is completed.

[0105] Furthermore, after receiving the data flow value information sent by the target server based on the third preset transmission format, the data flow value information can be parsed using the corresponding preset parsing library or preset parsing tool. If the data of the data flow value information exceeds the preset data range, it may indicate the existence of a fault; preset rules can be used to verify the correctness of the data flow value information to ensure that the received data flow value information complies with the predetermined standards and format, thereby ensuring data consistency.

[0106] It should be pointed out that if the data obtained first is data flow information, the data flow name information and data flow unit information in the data flow information can be displayed on the data flow display interface based on the preset display interface, until the data flow value information is obtained, and then the data flow value information can be displayed on the data flow display interface based on the preset display interface, wherein the data flow group information can be selected and displayed as needed, and no specific limitation is made here.

[0107] It can be seen from the above that before sending the key information of the target vehicle model to the target server end with which a communication connection has been established in advance through a preset data transmission method, the client and the target server end first establish a communication connection so that data flow information can be transmitted between the client and the target server end. The client determines the corresponding command reply information based on the data flow command information in the data flow information sent by the target server end, so that the target server end completes the calculation of the data flow value based on the command reply information and using the preset data flow algorithm in the database. In this way, it is possible to effectively realize a diagnostic software data flow that cannot be reverse cracked, prevent the occurrence of piracy and reverse engineering, and thus ensure the security of the data flow information.

[0108] See also Figure 2 As shown, the present invention discloses a specific online data stream display method, which is applied to a target server, wherein the target server has pre-established a communication connection with a corresponding client that has installed a preset diagnostic tool; the method comprises:

[0109] Step S21: receiving key information of the target vehicle model sent by the client through a preset data transmission method, and acquiring corresponding data stream information from a database based on the key information.

[0110] Step S22: Send the data flow information to the client so that the client can execute commands based on the data flow command information in the data flow information to obtain corresponding command reply information.

[0111] Step S23: after receiving the command reply information sent by the client based on the preset data upload method, determine the corresponding data flow value information based on the command reply information and through the preset data flow algorithm in the database.

[0112] Step S24: Send the data stream value information to the client so that the client can use the data stream value information and the data stream information to complete the online data stream display operation corresponding to the target vehicle model.

[0113] Among them, for more specific working processes of the above steps, reference can be made to the corresponding contents disclosed in the aforementioned embodiments, which will not be repeated here.

[0114] As can be seen from the above, the target server side obtains the data flow information corresponding to the key information from the database by receiving the key information of the target vehicle model sent by the client, so that the client can execute the command based on the data flow command information in the data flow information sent by the target server to obtain the command reply information corresponding to the data flow command information. After the target server side receives the command reply information uploaded by the client, it uses the preset data flow algorithm in the database to calculate the command reply information to obtain the data flow value information corresponding to the command reply information. In this way, placing the data flow algorithm on the target server side can avoid the leakage of the data flow algorithm and effectively improve the data protection of the software data flow.

[0115] Accordingly, see Figure 3 As shown, the present application also provides an online data stream display device, which is applied to a client that has installed a preset diagnostic tool, including:

[0116] The key information sending module 11 is used to send the key information of the target vehicle model to the target server end with which the communication connection has been established in advance through a preset data transmission method, so that the target server end obtains the corresponding data stream information from the database based on the received key information;

[0117] A command execution module 12 is used to execute a command based on the data flow command information in the data flow information after receiving the data flow information sent by the target server, so as to obtain corresponding command reply information;

[0118] A reply information sending module 13 is used to send the command reply information to the target server end based on a preset data upload method, so that the target server end determines the corresponding data flow value information based on the command reply information and through a preset data flow algorithm in the database;

[0119] The data stream display module 14 is used to complete the online data stream display operation corresponding to the target vehicle model by using the data stream value information and the data stream information after receiving the data stream value information sent by the target server.

[0120] It can be seen from the above that before sending the key information of the target vehicle model to the target server end with which a communication connection has been established in advance through a preset data transmission method, the client and the target server end first establish a communication connection so that data flow information can be transmitted between the client and the target server end. The client determines the corresponding command reply information based on the data flow command information in the data flow information sent by the target server end, so that the target server end completes the calculation of the data flow value based on the command reply information and using the preset data flow algorithm in the database. In this way, it is possible to effectively realize a diagnostic software data flow that cannot be reverse cracked, prevent the occurrence of piracy and reverse engineering, and thus ensure the security of the data flow information.

[0121] In some specific implementations, the online data stream display device may further include:

[0122] A connection request sending unit is used to initiate a connection request to the target server based on the data stream and a preset full-duplex communication protocol after entering the data stream corresponding to the target vehicle model through the installed preset diagnostic tool, so that the target server can establish a communication connection with the client of the installed preset diagnostic tool based on the connection request.

[0123] In some specific implementations, the key information sending module 11 may specifically include:

[0124] The key information sending completion unit is used to send key information including the identity identification information, software version information, configuration information and electronic system configuration information of the target vehicle model to the target server end with which a communication connection has been established in advance through a preset data transmission method, the preset full-duplex communication protocol and the first preset information transmission format.

[0125] In some specific implementations, the command execution module 12 may specifically include:

[0126] A data flow information acquisition unit, used to acquire the data flow information including the data flow command information sent by the target server, and execute the data flow command information;

[0127] A first reply information determining unit, configured to determine, during the process of executing a command, for a first data stream command that has been normally responded to, first command reply information corresponding to the first data stream command based on a corresponding response result;

[0128] A second reply information determining unit, configured to determine, for a second data stream command to which a negative response has been given and to which no response information exists, second command reply information representing an empty set corresponding to the second data stream command;

[0129] A command reply information determining unit is used to determine corresponding command reply information based on the first command reply information, the second command reply information and a second preset information transmission format.

[0130] In some specific implementations, the data stream display module 14 may specifically include:
