Description

Technical Field

[0001] The present invention relates to the technical field of vehicle information entry and function detection, and particularly to an information entry system and function detection method for an on-vehicle information collection terminal of a heavy truck. Background Art

[0002] During the cab assembly process, after various terminals such as a vehicle positioning terminal and an emission terminal are assembled to designated positions, a paper strip with terminal number information in the accessories carried by the terminal is placed at a designated position in the cab. After the cab is assembled, when the whole vehicle comes off the production line, the vehicle identification code VIN or vehicle serial number and terminal number information are successively entered using a computer or an in-line industrial computer, and the vehicle information is bound to the terminal information in the background; the existing entry method is manual operation to enter vehicle information and vehicle information collection terminal information, so the cycle time is long, and it is impossible to ensure that the entered vehicle information is completely correct. There are situations such as the paper strip with terminal number information being placed incorrectly, manual entry errors, and the paper strip with terminal number information being damaged and unable to be entered.

[0003] At the same time, before the vehicle is warehoused, it is necessary to detect the working conditions of the vehicle terminal. The operation process is that the driver makes a manual judgment on the terminal according to the performance of the vehicle terminal after being installed; if the vehicle has a loan, it is necessary to continue to activate the vehicle locking function on the detection computer. The debugging driver goes to the locked vehicle and tries to start the vehicle by ignition. If the ignition is successful, he returns to the detection office to unlock the vehicle locking function of the vehicle, and then returns to the vehicle and tries to start the vehicle by ignition again. If the ignition is successful, it is determined that this function is normal and the detection process ends. Therefore, it can be seen that the detection process requires the debugging staff to travel back and forth between the vehicle and the detection office, lengthening the debugging cycle; the vehicle locking function and other functions are manually tested, and there are situations of misjudgment. Summary of the Invention

[0004] The present invention provides an information entry and function detection method for an on-vehicle information collection terminal of a heavy truck, which solves the problems of cumbersome transmission process of terminal information using paper strips and manual entry errors during the entry and detection of existing vehicle information collection terminals; at the same time, it solves the problems of easy errors and cumbersome detection during the detection process after the terminal comes off the production line through manual detection.

[0005] In order to solve the problems in the above background art, the present invention is realized through the following technical solutions:

[0006] An information entry system for an on-vehicle information collection terminal of a heavy truck includes a product design platform, a vehicle information collection terminal management platform, and a production diagnosis device;

[0007] The product design platform generates a design part product structure data file of the vehicle, and extracts the vehicle configuration information in the design part product structure data file and converts it into a vehicle configuration code;

[0008] The vehicle information collection terminal management platform requests the vehicle configuration code from the product design platform, transfers the vehicle configuration code, enters and transfers the vehicle configuration information to the information management platform, and transfers the entered vehicle configuration information to the production diagnostic device, receives the vehicle information of the production vehicle returned by the production diagnostic device, determines whether the vehicle terminal is working properly, and feeds back the determination result of the vehicle information collection terminal management platform to the production diagnostic device;

[0009] The production diagnostic device is connected to the in-vehicle diagnostic system interface of the production vehicle, receives the vehicle configuration information transferred by the vehicle information collection terminal management platform, and transmits the vehicle information collected from the in-vehicle diagnostic system interface of the production vehicle back to the vehicle information collection terminal management platform, and displays the feedback determination result of the vehicle information collection terminal management platform to the operator or the debugging staff, and the operator or the debugging staff determines whether the production vehicle is working properly based on the displayed detection result.

[0010] Furthermore, the design part product structure data file of the vehicle includes the vehicle-level details, the system-level details, and the details of each part; the details of each part form the system-level details, and the system-level details form the vehicle-level details; the vehicle-level details, the system-level details, and the details of each part are all identified using letters, numbers, or a combination of letters and numbers; the vehicle configuration code is maintained in the system-level details or the details of each part.

[0011] Furthermore, the vehicle configuration code is maintained in the system-level details, and the system-level details transfer the vehicle configuration code to the vehicle-level details, making the vehicle configuration code an attribute of the vehicle-level details; the vehicle configuration code is maintained in the details of each part, and the details of each part transfer the vehicle configuration code to the vehicle-level details through the system-level details, making the vehicle configuration code an attribute of the vehicle-level details.

[0012] Furthermore, the definition rule of the vehicle configuration code is as follows: First, sort out the vehicle configuration types required by the vehicle information collection terminal platform. According to the number of configurations, define the length of the configuration code in combination with the configuration code form for each configuration type. After determining the length of the configuration code, then define the position and representation method of each configuration type in the total configuration code to form a configuration code definition table. The configuration code definition table is a file for the vehicle information collection terminal input platform to parse the configuration code; the configuration code is in binary or hexadecimal.

[0013] Further, the vehicle information collection terminal management platform requests a configuration code from the product design platform using the vehicle identification number VIN or the vehicle indication section VIS and the vehicle factory production serial number; the product design platform produces the vehicle identification number VIN after the vehicle order is determined and enters the production plan; when the vehicle rolls off the production line, the production diagnostic device can also request and transmit vehicle configuration information from the vehicle information collection terminal management platform through the vehicle indication section VIS in the vehicle identification number VIN.

[0014] Further, the production diagnostic device reads the vehicle on-board diagnostic system network message information through the vehicle's on-board diagnostic system OBD. The production diagnostic device is equipped with a display screen, an operating system, and diagnostic software. The operating system is any one of the windows operating system, the linux operating system, or the android operating system. The production diagnostic device is connected to the on-board diagnostic system OBD through the diagnostic software to read the vehicle on-board diagnostic system network message information.

[0015] Further, after receiving the vehicle configuration code information, the production diagnostic device sends a request for obtaining the terminal number in the on-board diagnostic system network for the vehicle configuration type described in the vehicle configuration information. After receiving the request, the vehicle information collection terminal management platform sends the vehicle information collection terminal signal to the on-board diagnostic system network. The production diagnostic device captures and records it and sends it to the vehicle information collection terminal management platform together with the vehicle identification number VIN information. After the vehicle information collection terminal management platform returns the vehicle information collection terminal input result, the result is displayed to the operator or the debugging staff through the display screen.

[0016] A method for detecting the functions of a heavy truck on-board information collection terminal, which is applied to the heavy truck on-board information collection terminal information input system described in any one of the above. The detection method for the vehicle information collection terminal management platform to judge whether the vehicle terminal is working properly includes a vehicle signal automatic detection method and a vehicle function automatic detection method;

[0017] The vehicle signal automatic detection method is as follows: It is agreed that 20 minutes after the vehicle entry is completed, the vehicle completes the off-line work and enters the vehicle debugging process. After the vehicle information collection terminal goes online, the vehicle information collection terminal management platform collects the vehicle information collection terminal signal through active collection or passive collection;

[0018] The active collection is as follows: The vehicle information collection terminal management platform sends a detection instruction to the vehicle information collection terminal. When the vehicle information collection terminal is powered on and working, it continuously sends the data stream required for detection to the vehicle information collection terminal management platform. When the vehicle information collection terminal management platform receives sufficient data and determines that the vehicle information collection terminal is working properly, the vehicle information collection terminal management platform sends an instruction to end the detection to the vehicle information collection terminal, and the vehicle information collection terminal ends the signal detection process and resumes the normal working state;

[0019] The passive collection is as follows: When the vehicle information collection terminal is powered on and working, it normally sends a data stream to the vehicle information collection terminal. The vehicle information collection terminal management platform selects the data signals to be detected from the sent data stream for detection;

[0020] The vehicle function automatic detection method is that the vehicle information collection terminal management platform detects the functions to be detected according to the vehicle configuration coding information, and the detection process includes active detection and passive detection;

[0021] The active detection is as follows: The vehicle information collection terminal management platform sends an instruction to the vehicle information collection terminal. After the operator operates the vehicle according to the defined process, the vehicle information collection terminal obtains the operation message and the response message of the vehicle to the operation message during the operator's operation in the on-vehicle diagnostic system network, and transmits the response message to the vehicle information collection terminal management platform. The vehicle information collection terminal management platform judges the vehicle function according to the content of the response message;

[0022] The passive detection is as follows: The debugging staff uses the functions of the vehicle according to the defined operation specifications. The vehicle information collection terminal collects the characterization messages of each function execution in the on-vehicle diagnostic system network, sends the messages to the vehicle information collection terminal management platform to check the characterization messages of each function execution in the on-vehicle diagnostic system network, so as to judge whether the functions of the vehicle are working properly;

[0023] During the active detection or passive detection process, the debugging staff can view whether the detection items are qualified in real time through the production diagnostic equipment or by using a computer to log in to the vehicle information collection terminal management platform, and repair the unqualified items. After the repair, continue the operation for detection.

[0024] Compared with the prior art, the present invention has the following beneficial technical effects:

[0025] 1. In the process of terminal information entry, no longer use a note with terminal number information to transmit the terminal number information. The production diagnostic equipment directly reads the vehicle terminal information assembled on the vehicle in real time, solving the problem of incorrect vehicle information entry caused by misplacing or losing the note with terminal number information.

[0026] 2. The information input by the vehicle information collection terminal is changed from manual input to automatic transmission by the background, which solves the problem of incorrect manual input of vehicle configuration information.

[0027] 3. The function detection of the vehicle information collection terminal is judged by the vehicle information collection terminal management platform and displayed by the production diagnostic equipment. During the warehousing detection process, there is no need for the debugging workers to shuttle back and forth between the detection office and the vehicle to be detected, reducing the process of manual judgment and ensuring the quality of the vehicle warehousing.

[0028] 4. The process of information input and function detection of the vehicle information collection terminal is automated detection, saving more than 50% of the time. Description of the Drawings

[0029] Figure 1 It is a flow schematic diagram of the present invention;

[0030] Figure 2 It is a formation process diagram of maintaining the vehicle configuration code in the details of each component of the present invention;

[0031] Figure 3 It is a formation process diagram of maintaining the vehicle configuration code in the system-level details of the present invention. Detailed Embodiment

[0032] As Figure 1 shown, the information input system of the on-vehicle information collection terminal of a heavy truck includes a product design platform, a vehicle information collection terminal management platform, and a production diagnostic equipment;

[0033] The product design platform generates a design component product structure data file of the vehicle, and extracts the vehicle configuration information in the design component product structure data file and converts it into a vehicle configuration code;

[0034] The vehicle information collection terminal management platform requests the vehicle configuration code from the product design platform, transmits the vehicle configuration code, inputs and transmits the vehicle configuration information to the information management platform, and transmits the already input vehicle configuration information to the production diagnostic equipment, receives the vehicle information of the production vehicle returned by the production diagnostic equipment, judges whether the vehicle terminal is working properly, and feeds back the judgment result of the vehicle information collection terminal management platform to the production diagnostic equipment;

[0035] The production diagnostic equipment is connected to the on-vehicle diagnostic system interface of the production vehicle, receives the vehicle configuration information transmitted by the vehicle information collection terminal management platform, and transmits the vehicle information collected from the on-vehicle diagnostic system interface of the production vehicle back to the vehicle information collection terminal management platform, and displays the feedback judgment result of the vehicle information collection terminal management platform to the operator or the debugging worker, and the operator or the debugging worker judges whether the production vehicle is working properly through the displayed detection result.

[0036] The design details of the vehicle include vehicle-level details, system-level details, and details of each component; the details of each component form the system-level details, and the system-level details form the vehicle-level details; the vehicle-level details, system-level details, and details of each component are all identified using letters, numbers, or a combination of letters and numbers; the vehicle configuration code is maintained in the system-level details or the details of each component.

[0037] For example, the letter A is used before the vehicle details, the letter B is used before the system details, and the letter C is used before the component details. Since multiple system details are required to be included under one vehicle detail, when differentiating each system detail, special fields are often defined for distinction. For example, the 2-4 digits after the first letter are defined as special fields representing the system type. The A system is defined as 001, the B system is defined as 002, and other system names are defined analogously. Then the detail form of the A system is B*001*, the detail form of the B system is B*002*, and the method of differentiating the part numbers of the special parts of each system in the components is the same as the system differentiation method. The detail form of the components of the A system is C*001*, and the detail form of the components of the B system is C*002*.

[0038] Such as Figure 2 shown, it is a process diagram for maintaining the vehicle configuration code in the details of each component;

[0039] Such as Figure 3 shown, it is a process diagram for maintaining the vehicle configuration code in the system-level details;

[0040] The vehicle configuration code is maintained in the system-level details, and the system-level details transfer the vehicle configuration code to the vehicle-level details, making the vehicle configuration code an attribute of the vehicle-level details; the vehicle configuration code is maintained in the details of each component level, and the details of each component level transfer the vehicle configuration code to the vehicle-level details through the system-level details, making the vehicle configuration code an attribute of the vehicle-level details.

[0041] There are mainly two advantages in using the vehicle configuration code to transfer vehicle configuration information. 1. The vehicle information collection terminal management platform is an Internet platform for communicating with the outside world, and the product design platform is an internal network platform of the enterprise. If the two platforms are one platform, it is easy to cause the risk of design information leakage. After using the code transfer, only the defined configuration information is transferred, which is safe and reliable. 2. Generally, the enterprise's design platform is established earlier than the vehicle information collection terminal management platform. The design platform does not have the vehicle information collection terminal information management ability at the beginning of the design. If it is costly to transform the design platform, it is better to build a new platform with lower management cost and higher efficiency.

[0042] The definition rules for vehicle configuration codes are as follows: First, sort out the types of vehicle configurations required by the vehicle information collection terminal platform. According to the number of configurations, combine the configuration type with the configuration code form to define the length of the configuration code. After determining the length of the configuration code, define the position and representation method of each configuration type in the total configuration code to form a configuration code definition table. The configuration code definition table is a file for the vehicle information collection terminal input platform to parse the configuration code; the configuration code is in binary or hexadecimal.

[0043] Taking the maintenance of the configuration code in each parts detail as an example, the process of forming the configuration code is as follows: Define the length of the vehicle configuration code as 4 and use the binary parsing method. Then each bit in the code has only two states, 0 or 1. If 0 is defined as the configuration does not exist and 1 is defined as the configuration exists, the first and second bits in the configuration code correspond to attributes A and B in system A, and the third and fourth bits in the configuration code correspond to attributes C and D in system B. In the parts detail of A in the system details, the maintained attribute is 1, and the maintained attribute of parts detail B is 0. In the parts detail of B in the system details, the maintained attribute of parts detail C is 1, and the maintained attribute of parts detail D is 0. The finally formed vehicle configuration code is 0101 (the rightmost bit is defined as the first bit during the code definition process). After corresponding to the definition table, the translated vehicle configuration is that for system A, configuration A exists and configuration B does not exist; for system B, configuration C exists and configuration D does not exist.

[0044] The vehicle information collection terminal management platform requests the configuration code from the product design platform using the vehicle identification number VIN or the vehicle indication part VIS and the production serial number of the vehicle factory; the product design platform generates the vehicle identification number VIN after the vehicle order is determined and enters the production plan; when the vehicle rolls off the production line, the production diagnostic device can also request and transfer the vehicle configuration information to the vehicle information collection terminal management platform through the vehicle indication part VIS in the vehicle identification number VIN.

[0045] The production diagnostic device reads the vehicle on-board diagnostic system network message information through the vehicle's on-board diagnostic system OBD. The production diagnostic device is equipped with a display screen, an operating system, and diagnostic software. The operating system is any one of the Windows operating system, the Linux operating system, or the Android operating system. The production diagnostic device connects to the on-board diagnostic system OBD through the diagnostic software to read the vehicle on-board diagnostic system network message information.

[0046] The vehicle identification number VIN information can also be directly obtained from the vehicle engine ECU controller in the on-board diagnostic system network because after the national IV vehicles, the ECU information contains the vehicle identification number VIN information.

[0047] After receiving the configuration coding information of the vehicle, the production diagnostic device sends a request to obtain the terminal number in the on-vehicle diagnostic system network for the vehicle configuration type described in the vehicle configuration information. After receiving the request, the vehicle information collection terminal installed on the vehicle sends the vehicle information collection terminal number signal into the on-vehicle diagnostic system network. The production diagnostic device captures and records it and sends it to the vehicle information collection terminal management platform together with the vehicle identification code VIN information. After the vehicle information collection terminal management platform returns the input result of the vehicle information collection terminal, the result is displayed to the operator through the display screen.

[0048] A method for detecting the functions of a heavy truck vehicle information collection terminal, which is applied to the heavy truck vehicle information collection terminal information input system described in any one of the above. The detection method for the vehicle information collection terminal management platform to judge whether the vehicle terminal is working properly includes a vehicle signal automatic detection method and a vehicle function automatic detection method;

[0049] The vehicle signal automatic detection method is as follows: It is agreed that 20 minutes after the vehicle input is completed, the vehicle completes the off-line work and enters the vehicle debugging process. After the vehicle information collection terminal goes online, the vehicle information collection terminal management platform collects the vehicle information collection terminal signal through active collection or passive collection;

[0050] Active collection: The vehicle information collection terminal management platform sends a detection instruction to the vehicle information collection terminal. When the vehicle information collection terminal is powered on and working, it always sends the data stream required for detection to the vehicle information collection terminal management platform. When the vehicle information collection terminal management platform receives sufficient data and judges that the vehicle information collection terminal is working properly, the vehicle information collection terminal management platform sends an instruction to end the detection to the vehicle information collection terminal, and the vehicle information collection terminal ends the signal detection process and returns to the normal working state

[0051] Passive collection: When the vehicle information collection terminal is powered on and working, it normally sends a data stream to the vehicle information collection terminal. The vehicle information collection terminal management platform selects the data signals to be detected from the sent data stream for detection;

[0052] The vehicle function automatic detection method: The vehicle information collection terminal management platform detects the functions to be detected according to the vehicle configuration coding information, and the detection process includes active detection and passive detection;

[0053] Active detection is as follows: The vehicle information collection terminal management platform sends an instruction to the vehicle information collection terminal. After the operator operates the vehicle according to the defined technological process, the vehicle information collection terminal obtains the operation message during the operator's operation and the response message of the vehicle to the operation message in the on-vehicle diagnostic system network, and transfers the response message to the vehicle information collection terminal management platform. The vehicle information collection terminal management platform judges the vehicle function according to the content of the response message;

[0054] For example, for the detection of the vehicle remote locking function, it is agreed to detect this function 20 minutes after the vehicle information collection terminal is entered. When the debugging operator powers on the vehicle again, wait for 10 seconds and then perform an ignition operation on the vehicle (during this period, the vehicle information collection terminal sends an online notification to the vehicle information collection terminal management platform, and the vehicle information collection terminal management platform sends a locking instruction to the vehicle). The debugging operator performs three ignition operations on the vehicle, with an interval of 3 seconds each time. If the ignition is not successful each time, wait for 20 seconds and then the debugging operator performs an ignition again. If the ignition is successful this time, it indicates that the vehicle remote locking function is normal. During the ignition process, the vehicle information collection terminal collects the ignition signal and the feedback signal of engine ignition refusal in the vehicle on-vehicle diagnostic system network and feeds the signals back to the vehicle information collection terminal management platform. The debugging operator performs three ignitions as required to avoid error phenomena caused by packet loss during signal collection and transmission. 15 seconds after the vehicle information collection terminal management platform receives a complete detection message and judges that the vehicle remote locking function is normal, it sends an unlocking signal to the vehicle. At this time, after the vehicle is normally ignited, it sends a signal of normal vehicle ignition to the vehicle information collection terminal management platform. At this time, the vehicle information collection terminal management platform judges that this function is normal.

[0055] Passive detection is as follows: The debugging operator uses the functions of the vehicle according to the defined operation specifications. The vehicle information collection terminal checks the execution representation messages of each function in the on-vehicle diagnostic system network by collecting them and sending the messages to the vehicle information collection terminal management platform, so as to judge whether the functions of the vehicle are working properly;

[0056] During the active detection or passive detection process, the debugging operator can view whether the detection items are qualified in real time through the production diagnostic equipment or by using a computer to log in to the vehicle information collection terminal management platform, and repair the unqualified items. After the repair, continue the operation for detection.
