Description

Data processing method, system and related equipment

Technical Field

The present invention relates to the field of computer application programs, and in particular, to a data processing method, system and related device.

Background

Along with the development of society and the progress of scientific technology, technologies such as electronic technology, automation technology and electronic computer technology play an extremely important role in the design and production of automobiles, so on one hand, the automation degree of the automobiles is higher and higher, the performance is more superior, the operation is more convenient and flexible, but on the other hand, higher requirements are provided for automobile maintenance and detection, and the like, but the traditional manual monitoring cannot meet the maintenance requirements of novel automobiles, and in addition, the fault detection mode based on the traditional communication mode is increasingly exposed to more defects (for example, the reliability in the data transmission process cannot be guaranteed).

For example, when a vehicle has a fault, data exchange is generally performed between the diagnostic device and an Electronic Control Unit (ECU) of the vehicle based on a conventional communication manner to read a fault code stored in the ECU. However, before the diagnostic device acquires the fault code, the reliability of the diagnostic command sent by the diagnostic device in the data transmission process cannot be ensured. Since the ECU usually checks the parameter information carried in the diagnostic command by using redundancy check, when the diagnostic device transmits the parameter information (for example, 1110) carried in the diagnostic command to the ECU through the channel, distortion may exist, and the diagnostic command received by the ECU is a distorted diagnostic command (for example, 1101), since the values before and after redundancy check are equal, the ECU reads another fault code according to the distorted diagnostic command, and the reliability of the diagnostic command corresponding to the fault code in the transmission process is reduced.

In addition, in the process of data transmission, because the transmission rate of the transmission code element on the automobile bus has the maximum limit, when the transmission rate exceeds the maximum limit, the transmitted data is unstable, and further the data is damaged, so that the data is retransmitted, and the transmission efficiency of the data is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "including" and "having," and any variations thereof, in the description and claims of this invention and the above-described drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The following are detailed below.

Fig. 1 is a schematic flow chart of a data processing method according to an embodiment of the present invention. As shown in fig. 1, the method at least comprises:

step S101, a diagnosis device acquires a diagnosis command of a current vehicle;

the diagnosis device can comprise an upper computer and a lower computer; the upper computer and the lower computer can be connected in a wired or wireless network connection mode (for example, a connection mode such as Bluetooth and a wireless local area network (Wlan)); in addition, the upper computer can also acquire the equipment connection information of the lower computer through scanning forms such as two-dimensional codes.

The upper computer can be used for providing a corresponding function selection interface for a user (for example, the user can perform functions of speed measurement, fault detection and the like on the current vehicle on the upper computer), and can also be used for displaying a diagnosis result after receiving the diagnosis result transmitted by the lower computer.

The upper computer can comprise terminal equipment with a network connection function, such as a smart phone, a personal computer, a tablet personal computer and a notebook computer.

The lower computer is used for acquiring the instruction sent by the upper computer and reading corresponding data information (such as reading a data stream, reading a fault code and the like) from a vehicle-mounted device (namely a vehicle-mounted computer) according to the instruction.

Step S102, the diagnosis device extracts the diagnosis mode carried in the diagnosis command, processes the diagnosis command into a first diagnosis command and a second diagnosis command based on the diagnosis mode, and transmits the diagnosis commands to the vehicle-mounted device in a dual-channel transmission mode;

specifically, the diagnostic device may extract a diagnostic mode carried in the diagnostic command, and if the diagnostic mode is a reliability diagnostic mode, copy the diagnostic command into a first diagnostic command and a second diagnostic command carrying the same parameter content, and transmit the first diagnostic command and the second diagnostic command to the vehicle-mounted device through a dual-channel transmission manner; optionally, if the diagnosis mode is the efficiency diagnosis mode, the diagnosis command is split into a first diagnosis command and a second diagnosis command carrying different parameter contents, and the first diagnosis command and the second diagnosis command are transmitted to the vehicle-mounted device in a dual-channel communication manner.

The diagnosis mode may be preset to a reliability diagnosis mode, or may be preset to an efficiency diagnosis mode.

Optionally, the diagnosis mode may be any one of a reliability diagnosis mode and an efficiency diagnosis mode, that is, the diagnosis device may automatically select the diagnosis mode according to the type of the diagnosis parameter. For example, when a user needs to write data in an on-board computer (ECU, electronic control unit), that is, the diagnostic parameter type is a parameter write type, the diagnostic apparatus may set the diagnostic mode to a reliability diagnostic mode, or may set the diagnostic mode to an efficiency diagnostic mode. When the diagnosis mode is a reliability diagnosis mode, the correctness of the written data can be checked to improve the reliability of data transmission. Optionally, if the diagnosis mode is the efficiency diagnosis mode, the diagnosis device may transmit the data to be written into the on-board computer to the on-board computer more quickly, so as to improve the efficiency of data transmission from the diagnosis device to the on-board computer.

The dual-channel communication mode mainly refers to the fact that double physical connecting lines are used for connecting the diagnosis device and the vehicle-mounted device on a communication layer, so that data (diagnosis commands and diagnosis results) to be transmitted are scattered on a plurality of communication channels to be transmitted, the baud rate of the current vehicle bus is prevented from exceeding a preset maximum threshold, the problem that data are unstable in a single-channel transmission mode in the prior art is further solved, and the transmission efficiency of the data to be transmitted can be improved.

Step S103, the vehicle-mounted device processes the acquired first diagnosis command and the acquired second diagnosis command, obtains and executes a target command, and generates a diagnosis result corresponding to the target command;

specifically, if the diagnosis mode is a reliability diagnosis mode, checking whether parameter contents carried in the acquired first diagnosis command and second diagnosis command are consistent based on the reliability diagnosis mode, if so, determining the first diagnosis command as a target command after checking, executing the target command after checking, and generating a diagnosis result corresponding to the target command; optionally, if the first diagnostic command and the second diagnostic command are not consistent, the first diagnostic command and the second diagnostic command sent by the diagnostic device are re-acquired.

For example, when the diagnostic mode is the reliability diagnostic mode, the on-board device may perform a verification process on a first diagnostic command and a second diagnostic command acquired from a dual channel (a first communication channel and a second communication channel) to compare whether parameter contents carried in the first diagnostic command and the second diagnostic command are consistent, and if so, may continue to execute the diagnostic command; if the data transmission rate is inconsistent, the distortion phenomenon in the data transmission process can be detected more accurately, so that the reliability of the data in the data transmission process can be improved. For example, the first diagnostic command and the second diagnostic command may each be in the form 1110 prior to data transmission, but after data transmission, since there may be distortion in the data during transmission through the channel, the first diagnostic command may be in the form of 1110, the second diagnostic command may be in the form of 1101 at which time, the in-vehicle device will determine that the data verification failed, namely, the data distortion exists in the data transmission process, so the first diagnosis command and the second diagnosis command transmitted by the diagnosis device based on the dual-channel communication mode can be obtained again until the on-board device determines that the data verification is successful, therefore, compared with the original redundancy check, based on the dual-channel communication mode, the vehicle-mounted device can acquire two paths of data, and by comparing the parameter contents carried in the two paths of data, the reliability of the data in the data transmission process can be effectively improved.

Optionally, if the diagnosis mode is an efficiency diagnosis mode, combining the acquired first diagnosis command and the acquired second diagnosis command based on the efficiency diagnosis mode to obtain a target command after combined processing, executing the target command after combined processing, and generating a diagnosis result corresponding to the target command.

For example, taking the case that the user needs to modify the parameter value of the transmitter as an example, in this case, the modification command (i.e., the diagnostic command) corresponding to the modification of the parameter value of the transmitter is AABB. When the diagnosis mode is the efficiency diagnosis mode, the on-board device may acquire a first diagnosis command (for example, AA) and a second diagnosis command (BB) corresponding to the modification command based on the dual-channel communication manner, and before data transmission, the diagnosis device may split the diagnosis command (AABB) into two diagnosis commands of AA and BB in advance based on the efficiency diagnosis mode, and distribute the two diagnosis commands on two channels for synchronous transmission, so that the data diagnosis device may acquire the target command corresponding to the modification of the parameter value of the engine more quickly, that is, at this time, the data diagnosis device may combine the acquired first diagnosis command and the acquired second diagnosis command to obtain the combined target command (AABB), execute the target command to modify the parameter value of the transmitter, and generate a diagnosis result corresponding to the target command after modification (for example, the parameters of the engine have been successfully modified).

Step S104, the vehicle-mounted device returns the diagnosis result to the diagnosis device through the dual-channel transmission mode;

specifically, if the diagnosis mode is the reliability diagnosis mode, the in-vehicle device may copy the diagnosis result into a first diagnosis result and a second diagnosis result, and return the first diagnosis result and the second diagnosis result to the diagnosis device based on the dual-channel communication manner;

when the diagnosis mode is the reliability diagnosis mode, the method for copying and sending the diagnosis result by the vehicle-mounted device may refer to the description of the method for copying and sending the diagnosis command by the diagnosis device, and will not be described herein again.

Optionally, if the diagnosis mode is the efficiency diagnosis mode, the on-board device may further split the diagnosis result into a first diagnosis result and a second diagnosis result, and return the first diagnosis result and the second diagnosis result to the diagnosis device based on the dual-channel communication manner;

when the diagnosis mode is the efficiency diagnosis mode, the manner in which the on-board device splits and transmits the diagnosis result may refer to the description of the manner in which the diagnosis device splits and transmits the diagnosis command, which will not be described herein again.

Step S105, the diagnostic device performs data processing on the diagnostic result based on the diagnostic mode.

Specifically, the diagnostic device processes the acquired first diagnostic result and the acquired second diagnostic result based on the diagnostic mode to obtain a processed target result, and controls a display to display the processed target result;

and if the diagnosis mode is a reliability diagnosis mode, verifying the acquired first diagnosis result and the second diagnosis result, obtaining a target result after verification when verification is successful, and controlling a display to display the target result after verification.

For example, taking the obtaining of the vehicle speed of the current vehicle as an example, when the diagnostic mode is the reliability diagnostic mode, the diagnostic device may obtain a speed value corresponding to the vehicle speed of the current vehicle (for example, the speed value in the first diagnostic result may be CCDD), and if the speed value in the second diagnostic result obtained by the diagnostic device is also CCDD, the diagnostic device may further determine that the verification is successful, that is, may use the speed value in the first diagnostic result as the target result corresponding to the vehicle speed of the current vehicle, and display the speed value CCDD of the current vehicle on the display.

If the diagnosis mode is an efficiency diagnosis mode, combining the acquired first diagnosis result and the acquired second diagnosis result to obtain a target result after combined processing, and controlling a display to display the target result after combined processing.

For example, taking the obtaining of the vehicle speed of the current vehicle as an example, when the diagnostic mode is the efficiency diagnostic mode, the diagnostic device may obtain a speed value corresponding to the vehicle speed of the current vehicle (for example, the speed code value in the first diagnostic result may be CC, and the speed code value in the second diagnostic result is DD), and at this time, the diagnostic device may further combine the first diagnostic result and the second diagnostic result to obtain a target result corresponding to the vehicle speed of the current vehicle (for example, the speed value corresponding to the combined CCDD code is 30 kilometers per hour), and display the speed value of the current vehicle on the display at 30 kilometers per hour.

Further, please refer to fig. 2, which is a flowchart of another data processing method according to an embodiment of the present invention, and as shown in fig. 2, the method may include:

step S201, a diagnosis device identifies parameter diagnosis types of a current vehicle, wherein the parameter diagnosis types comprise a parameter writing type and a parameter reading type;

the parameter writing type refers to that a parameter diagnosis function selected by a user in a selection interface belongs to a function which needs to modify the parameters of the current vehicle;

the parameter writing type refers to that a parameter diagnosis function selected by a user in a selection interface belongs to a function of reading the parameter of the current vehicle;

the diagnosis device may include an upper computer and a lower computer, wherein the description of the upper computer and the lower computer refers to the description of the upper computer and the lower computer in the embodiment corresponding to fig. 1, which will not be described herein again.

Step S202, if the parameter diagnosis type is a parameter write-in type, acquiring a first parameter packet in a preset parameter configuration table, and adding the first parameter packet to a diagnosis command of the current vehicle;

and the first parameter packet comprises a diagnosis mode and a diagnosis protocol corresponding to the parameter writing type.

The parameter configuration table comprises parameters such as baud rate of data transmission, a diagnosis protocol, pins, a diagnosis mode, diagnosis parameter types and the like;

the diagnostic protocol may be a keyword communication protocol (KWP2000) based on a K line or a keyword communication protocol of a Controller Area Network (CAN) bus, so that the diagnostic device and the in-vehicle device CAN transmit data based on the diagnostic protocol.

Among them, a Controller Area Network (CAN) is a serial communication protocol bus for real-time applications, which CAN use twisted pair wires to transmit signals, and is one of the most widely used field buses in the world. The features of the CAN protocol may include serial data communication for integrity, real-time support, transmission rates up to 1Mb/s, and 11-bit addressing and error detection capabilities.

The diagnosis mode may be a reliability diagnosis mode or an efficiency diagnosis mode.

For example, when a user needs to modify a value of a current vehicle transmitter, the diagnostic device may select a function of modifying the value of the transmitter in a selection interface according to the user, that is, at this time, the diagnostic device may recognize that the parameter diagnosis type is a parameter writing type, and further may find each parameter corresponding to the parameter writing type in a parameter configuration table for modifying the engine value. Specifically, see table 1 for a statistical table of the first parameter package according to the embodiment of the present invention.

TABLE 1

As shown in table 1, when the diagnostic parameter type is a parameter write type, the first parameter packet may include a maximum baud rate of data transmission, a diagnostic protocol, a pin, and a diagnostic mode; the diagnostic protocol may be a K-line protocol or a CAN-line protocol, which is mainly based on current settings of the vehicle when leaving the factory. However, the a pin corresponding to the transmitter system is determined by a free pin on the OBD connected to the diagnostic apparatus, for example, if the space pin of the current OBD is a pin 7, the diagnostic apparatus may use the pin 7 and the default pin 9 to connect to the pin 7 and the pin 9 of the OBD in the dual channel, respectively, for data transmission and communication.

Therefore, the diagnostic device can encapsulate each parameter in the first parameter packet and add the encapsulated data to the diagnostic command of the current vehicle, so that the subsequent on-board device can modify the parameter of the current transmitter after receiving the target command corresponding to the diagnostic command.

Similarly, for the process of acquiring the first parameter packet of other parameters of the current vehicle, the above description of the process of acquiring the first parameter packet of the transmitter parameter may also be referred to, and details will not be further described here.

Optionally, in step S203, if the parameter diagnosis type is a parameter reading type, a second parameter packet is obtained from a preset parameter configuration table, and the second parameter packet is added to the diagnosis command of the current vehicle;

the second parameter packet comprises a diagnosis mode and a diagnosis protocol corresponding to the parameter reading type;

the specific implementation process of step S203 can refer to step S202 above, except that the diagnosis command is used to read various items of data of the current vehicle, such as the vehicle speed of the current vehicle, the tire pressure of the current vehicle, and the fault code of the current vehicle.

Step S204, the diagnosis device obtains the diagnosis protocol, sets parameters of a first transceiver and a second transceiver according to the diagnosis protocol, and establishes a physical connection relation between the first transceiver and the second transceiver and a first channel and a second channel in a dual-channel communication mode respectively based on the parameters of the first transceiver and the second transceiver, so as to transmit a first diagnosis command and a second diagnosis command according to the physical connection relation subsequently.

Wherein the first transceiver and the second transceiver each provide a network interface for receiving and transmitting data related to the current vehicle, that is, the first transceiver and the second transceiver are operable to connect to corresponding pins (e.g., pin 9 and pin 7 of an automobile transmitter) in an automobile diagnostic system (OBD) in dual channel to establish a physical connection relationship between the first transceiver and the second transceiver and a first channel and a second channel in a dual channel communication manner, respectively, so that the diagnostic device can transmit and receive data to an on-board device of the current vehicle based on the physical connection relationship.

It can be seen that the first transceiver and the second transceiver each include a receiver and a transmitter, where the receiver is used for implementing the function of receiving the first diagnostic result and the second diagnostic result related to the current vehicle returned by the vehicle-mounted device in step S208, and the transmitter is used for implementing the function of sending the first diagnostic command and the second diagnostic command related to the current vehicle in step S206.

Step S205, the diagnosis device acquires a diagnosis command for the current vehicle;

for a specific implementation manner of step S205, reference may be made to the description of step S101 in the embodiment corresponding to fig. 1, and details will not be further described here.

Step S206, the diagnosis device extracts the diagnosis mode carried in the diagnosis command, processes the diagnosis command into a first diagnosis command and a second diagnosis command based on the diagnosis mode, and transmits the diagnosis commands to the vehicle-mounted device in a dual-channel transmission mode;

specifically, the diagnostic device may extract a diagnostic mode carried in the diagnostic command, copy the diagnostic command into a first diagnostic command and a second diagnostic command if the diagnostic mode is a reliability diagnostic mode, allocate the first diagnostic command to a first transceiver, synchronously allocate the second diagnostic command to a second transceiver, and transmit the first diagnostic command and the second diagnostic command to the vehicle-mounted device through the first transceiver and the second transceiver based on the physical connection relationship in the dual-channel communication mode, respectively; the first diagnosis command and the second diagnosis command are diagnosis commands carrying the same parameter content; optionally, if the diagnostic mode is the efficiency diagnostic mode, splitting the diagnostic command into a first diagnostic command and a second diagnostic command, allocating the first diagnostic command to the first transceiver, synchronously allocating the second diagnostic command to the second transceiver, and transmitting the first diagnostic command and the second diagnostic command to the vehicle-mounted device through the first transceiver and the second transceiver based on a physical connection relationship in a dual-channel communication manner; the first diagnosis command and the second diagnosis command are diagnosis commands which carry different parameter contents and are equal in size.

For example, taking the case that a user needs to read the tire pressure of the current vehicle from the vehicle-mounted device through the diagnosis device, the diagnosis device may acquire a diagnosis command (11111100) related to the tire pressure of the current vehicle, and if the diagnosis mode of the diagnosis device is the reliability diagnosis mode, the diagnosis device may copy the diagnosis command into a first diagnosis command (11111100) and a second diagnosis command (11111100), where the first diagnosis command and the second diagnosis command both carry a second parameter packet corresponding to the tire pressure of the current vehicle. Subsequently, the diagnostic device assigns the first diagnostic command (11111100) to a first transceiver and synchronously assigns the second diagnostic command (11111100) to a second transceiver, and further transmits the first and second diagnostic commands to an on-board device through the first and second transceivers.

Optionally, if the diagnostic mode of the diagnostic apparatus is the efficiency diagnostic mode, the diagnostic apparatus may split the diagnostic command into a first diagnostic command (1111) and a second diagnostic command (1100), where the first diagnostic command and the second diagnostic command are diagnostic commands with the same size but different parameter contents. Subsequently, the diagnostic device assigns the first diagnostic command (1111) to a first transceiver and synchronously assigns the second diagnostic command (1100) to a second transceiver, and further transmits the first diagnostic command and the second diagnostic command to an in-vehicle device through the first transceiver and the second transceiver.

Step S207, the vehicle-mounted device processes the acquired first diagnosis command and the acquired second diagnosis command, obtains and executes a target command, and generates a diagnosis result corresponding to the target command;

the on-board device can receive the first diagnosis command and the second diagnosis command transmitted by the diagnosis device through the dual-channel transmission mode through a third transceiver and a fourth transceiver.

Wherein the functions of the third transceiver and the fourth transceiver are similar to those of the first transceiver and the second transceiver, that is, the two transceivers in the vehicle-mounted device also include a receiver and a transmitter, wherein the receiver is used for realizing the function of receiving the first diagnostic command and the second diagnostic command related to the current vehicle sent by the diagnostic device in step S206, and the transmitter is used for realizing the function of sending the first diagnostic result and the second diagnostic result related to the current vehicle in step S208.

For a specific implementation manner of step S207, reference may be made to the description of step S103 in the embodiment corresponding to fig. 1, and details will not be further described here.

Step S208, the vehicle-mounted device processes the diagnosis result into a first diagnosis result and a second diagnosis result, and returns the first diagnosis result and the second diagnosis result to the diagnosis device through the dual-channel transmission mode;

specifically, if the diagnosis mode is a reliability diagnosis mode, the on-board device duplicates the diagnosis result into a first diagnosis result and a second diagnosis result, sends the first diagnosis result to a third transceiver, synchronously sends the second diagnosis result to a fourth transceiver, and returns the first diagnosis result and the second diagnosis result to the diagnosis device through the third transceiver and the fourth transceiver based on the dual-channel communication mode;

optionally, if the diagnostic mode is an efficiency diagnostic mode, splitting the diagnostic result into a first diagnostic result and a second diagnostic result, and sending the first diagnostic result to a third transceiver, and synchronously sending a second diagnostic result to a fourth transceiver, and returning the first diagnostic result and the second diagnostic result to the diagnostic apparatus through the third transceiver and the fourth transceiver based on the dual-channel communication manner;

wherein the third transceiver is connected to a first channel in the dual-channel communication mode; the fourth transceiver is connected to a second channel of the dual-channel communication scheme.

It can be seen that two transceivers are also present in the on-board device, which can provide a network interface for synchronously receiving and transmitting data related to the current vehicle. In addition, pins of the two transceivers (the third transceiver and the fourth transceiver) are connected with pins of the OBD in the dual-channel, so that the on-board device can realize reliable data transmission or shorten data transmission time between the on-board device and the diagnosis device in the dual-channel communication mode, and the data transmission efficiency is improved.

For example, the diagnostic mode is taken as the speed transmission mode, and the diagnostic result is used for representing that the tire pressure acquired to the current vehicle is 0.15 mpa. The on-board device can divide the diagnosis result into a first diagnosis result and a second diagnosis result so that the first diagnosis result and the second diagnosis result can be returned to the diagnosis device more quickly.

Step S209, the diagnostic device performs data processing on the first diagnostic result and the second diagnostic result based on the diagnostic mode.

Specifically, if the diagnosis mode is a reliability diagnosis mode, the diagnosis device checks whether the parameter contents carried in the acquired first diagnosis result and the second diagnosis result are consistent based on the reliability diagnosis mode, and if so, determines the first diagnosis result as a target result after checking processing, and controls a display to display the target result after checking processing;

optionally, if the diagnosis mode is an efficiency diagnosis mode, the diagnosis device combines the acquired first diagnosis result and the second diagnosis result based on the efficiency diagnosis mode to obtain a target result after combined processing, and controls a display to display the target result after verification processing;

in step S209, for a specific process of checking or combining the first diagnostic result and the second diagnostic result by the diagnostic apparatus, reference may be made to the specific description of the first diagnostic command and the second diagnostic command by the vehicle-mounted apparatus, which will not be further described here.
