Description

Technical Field

[0001] The present invention relates to the technical field of heavy vehicle maintenance, and in particular to an intelligent maintenance system and method for heavy vehicles. Background Art

[0002] As the level of informationization and intelligence of heavy-duty vehicles continues to improve, people's awareness of vehicle safety operation is gradually increasing, and the requirements for maintenance of heavy-duty vehicles are also increasing. Since the engine, gearbox, transfer case, axle, drive shaft, tire, suspension, fuel line, brake, battery and other structures of heavy-duty vehicles will affect the safe operation of the vehicle, these parts must be maintained regularly.

[0003] Since most heavy-duty vehicle owners pay close attention to the use of their vehicles but are short on vehicle maintenance and ignore the timing of vehicle maintenance, the current vehicle maintenance methods are mostly passive maintenance, that is, the vehicle production unit trains and informs by phone whether the vehicle needs maintenance, which parts to maintain, when to maintain, how to maintain, etc.

[0004] The inventors have discovered that the above-mentioned passive maintenance method has the following problems: since the driving conditions of each vehicle are different, the vehicle production unit estimates the maintenance time through estimation methods that are not accurate enough, and the vehicle may have exceeded the maintenance time when the owner is notified. This can easily cause damage to the vehicle performance and affect the vehicle's operating safety. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent maintenance system and method for heavy-duty vehicles. By setting a maintenance setting selection module, a maintenance data acquisition module, a maintenance judgment module and a maintenance operation module, the system can automatically monitor, judge and select vehicle maintenance items, accurately and punctually remind the driver which maintenance items to perform, automatically guide the driver on how to perform and complete the maintenance operations, and accurately determine whether the maintenance results are true and effective; passive maintenance is changed to active maintenance to prevent damage to vehicle performance and affect vehicle operation safety.

[0033] The maintenance setting selection module is used to set the maintenance project related information, the start conditions and maintenance qualification threshold of each maintenance project, and set the maintenance list and corresponding video tutorial for each maintenance project;

[0034] The maintenance data acquisition module acquires the vehicle mileage and delivery time in real time and monitors the vehicle signal data; the maintenance data acquisition module includes a data acquisition processing module and a maintenance calculation module. The data acquisition processing module is used to monitor the vehicle signal data. The maintenance calculation module includes a vehicle mileage counting module and a vehicle delivery timing module, which are used to acquire the vehicle mileage and delivery time in real time.

[0035] The maintenance judgment module is used to compare the collected data with the start conditions of the maintenance project. When the start conditions are met, the maintenance reminder module is used to remind the maintenance project to be carried out;

[0036] The maintenance operation module performs maintenance according to the maintenance list and corresponding video tutorials popped up by the maintenance prompt module. The maintenance video is recorded through the maintenance video equipment during the maintenance process. The maintenance video equipment adopts a mobile magnetic auto-focus camera, which can be moved freely according to the position of the maintenance item on the vehicle. The mobile magnetic auto-focus camera base can be adsorbed on the metal body of the vehicle body after being powered on.

[0037] The maintenance completion reminder module compares the recorded maintenance video with the video tutorial, and analyzes and compares the monitored vehicle signal data with the maintenance qualification threshold. When the maintenance meets the standards, it prompts that the maintenance is completed.

[0038] In the maintenance setting selection module of the present embodiment, maintenance item information packages are established respectively according to the performance and usage requirements of each component of the vehicle, specifically, a corresponding maintenance item directory is set: each maintenance item records a corresponding maintenance video tutorial, and at the same time, each maintenance item name and the corresponding maintenance video tutorial are associated with a hyperlink. Set the maintenance mileage, maintenance cycle, maintenance item trigger start conditions, maintenance item maintenance qualification threshold, signal status abnormality threshold, vehicle maintenance cycle, vehicle maintenance mileage, vehicle fault type, fault troubleshooting sequence, fault judgment basis and other data, and establish a data record and exception alarm interface. The purpose of setting the corresponding qualified threshold is to compare with the data collected by the maintenance data acquisition module and provide a judgment standard, so that the maintenance judgment module can prompt the maintenance through the maintenance prompt module after judging that the judgment standard is met.

[0039] Through the maintenance setting selection module, you can also initialize the vehicle mileage counter, initialize the vehicle delivery time timer, set the maintenance person's portrait, fingerprint, and identity information, etc. By comparing the maintenance person's information, you can automatically retrieve the maintenance personnel's basic information to determine whether they are qualified for maintenance.

[0040] The data acquisition and processing module is used to collect relevant vehicle driving status information in real time, collect the data of heavy vehicle monitoring signals, and convert the collected signal data according to the format required by the system. The collected data information includes: vehicle speed, air pressure, oil pressure, water temperature, oil temperature, shaft speed, flow, oil volume, voltage, current, height, angle, acceleration, etc. The monitoring and acquisition signal data obtained by the data acquisition and processing module is used to provide to the maintenance judgment module to determine whether maintenance is needed.

[0041] The maintenance calculation module includes a vehicle mileage counting module and a vehicle delivery timing module, which specifically configures corresponding counters and timers to count the vehicle mileage and vehicle delivery time in real time, and send them to the maintenance judgment module to determine whether maintenance is needed.

[0042] The maintenance judgment module is used to receive the monitoring signal data, vehicle real-time mileage and vehicle delivery time collected by the data collection and processing module and the maintenance calculation module, and set the qualified threshold value of the maintenance items through the maintenance setting selection module. When the vehicle is maintained, the maintenance judgment module analyzes and compares the collected vehicle status information with the set qualified threshold value of the maintenance items, and the system automatically determines whether the maintenance is up to standard (qualified) and whether the maintenance results are valid.

[0043] like Figure 3 As shown, the data collected by the data acquisition and processing module and the maintenance calculation module are sent to the maintenance judgment module for comparison and judgment to determine whether the real-time mileage of the vehicle reaches the mileage of the maintenance project, whether the vehicle delivery time reaches the maintenance project cycle, and whether the monitoring collection signal data obtained by the data acquisition and processing module is abnormal; thereby determining whether maintenance is required for the corresponding project. When any one of the three is met, the maintenance project can be triggered. After the maintenance is triggered, the maintenance setting selection module automatically selects the required maintenance project and prompts it through the maintenance prompt module.

[0044] The real-time vehicle mileage count, the real-time vehicle delivery time, and the judgment conditions set for the maintenance items selected by the system (vehicle mileage ≥ maintenance item set mileage or vehicle delivery time ≥ maintenance item set period) are compared to determine whether to start the corresponding maintenance item.

[0045] If maintenance is required, the maintenance reminder module will be used to give a reminder. The maintenance setting selection module will select the corresponding maintenance items and automatically pop up the items required for maintenance on the system operation display interface. The maintenance reminder module will remind the driver to perform maintenance on the corresponding items of the vehicle.

[0046] The maintenance reminder module uses interface display and voice prompts to remind the vehicle that maintenance is required, and also displays the maintenance items to be performed.

[0047] At the same time, maintenance operations are performed through the maintenance operation module. The system operation display interface prompts the driver to click the "maintenance operation" button.

The maintenance operation module mainly completes the operation functions such as viewing, retrieving, flipping through, returning maintenance items, and real-time recording of the maintenance process.

[0048] The maintenance completion reminder module, after the maintenance is completed, calls the vehicle status information related to the maintenance project collected in real time in the system, compares it with the set qualified threshold of the maintenance project, compares the recorded maintenance process video with the maintenance video tutorial, determines whether the vehicle maintenance is qualified, and identifies whether the maintenance result is valid. If the maintenance process video is true and valid and the vehicle status information after maintenance meets the standard, the system display interface will automatically pop up the "Maintenance Completed" text prompt. Click the "Maintenance Completed" button, and the system will automatically enter the next maintenance tracking and monitoring of the project.

[0049] Maintenance generation and viewing module: The maintenance generation and viewing module is used to collect the maintenance personnel information and real-time maintenance video after the maintenance is completed, and fill in the maintenance process information and maintenance results according to the maintenance information record form format; when the maintenance project is determined to be "maintenance completed", the maintenance generation and viewing module will collect the maintenance personnel information and real-time maintenance video, and fill in the maintenance process information and maintenance results according to the maintenance information record form format.

[0050] The data storage and recording module is used to store or export electronic maintenance information records and recorded maintenance videos. When the maintenance information record sheet for the maintenance project is generated, the system will automatically store the maintenance information record sheet and the real-time video of the maintenance process in the form of a package file. The system defines the package file name as "Maintenance sheet on XX / XX / XXXX". Click the "View Policy" button on the display interface to view, upload and download maintenance information.
