Description

Technical Field

[0001] The present invention relates to the technical field of vehicle management, and particularly relates to an intelligent management system and method for vehicle PDI repair. Background Art

[0002] With the rapid development of the global automotive industry, market competition has become increasingly fierce. Consumers' requirements for the quality and after-sales service of automotive products have reached an unprecedented level. Against this background, Pre-Delivery Inspection (PDI), as the last quality checkpoint before a new vehicle is delivered to consumers, has become increasingly important; PDI is related to the safety and reliability of vehicles, so research on vehicle PDI repair is of great significance.

[0003] At present, the full-process management of PDI repair is still in its infancy. Most factory terminals only have the actual passing point information of vehicles. Even though a whole-vehicle intelligent inspection management platform has been newly launched, for the specific location of vehicles in the PDI area, the management of repair destinations, the marking of batch defective repairs, and the repair status, etc., can only be manually managed by humans and cannot yet achieve digital monitoring management. Figure 1It is an existing full-process management system for PDI repair. The full-process management system for PDI repair includes: Quality entry: After the vehicle rolls off the production line and undergoes VQ inspection, quality non-conformity points are uniformly entered through the PC at the VQCHECK point; Mobile warehousing: The driver drives the vehicle to be repaired to the parking lot and parks it randomly in the vacant position; Finding the vehicle for repair: Send someone to the parking lot to drive the vehicle to be repaired back to the repair station for operation. If it is necessary to arrange priority repair for a specific vehicle, someone needs to be sent to search in each process area; Vehicle transfer: After a certain group completes the repair of problems in its field at the work station, it judges according to the fields to be repaired shown on the existing score card and drives the vehicle to the next group to be repaired. If there are no more fields to be repaired, it drives to the VQ re-inspection station; Inspection and departure: After all fields are repaired, VQ checks at the re-inspection parking space. If it is qualified, it drives onto the pallet chain and departs. If it is unqualified, write down the non-conformity points on the score card and send it to the parking lot in the responsible area. However, this system has the following disadvantages: First, this system only supports single-vehicle entry. When there are batch defects in vehicles, they can only be entered one by one, and it is impossible to batch mark the missing part information, that is, vehicles cannot be batch marked; Second, because the vehicles cannot be located and are parked randomly, if there are vehicles that need to be repaired and delivered with priority, this system cannot quickly locate the vehicles, and it is necessary to arrange personnel to search in places such as the workshop and the parking lot, that is, it is difficult to find the vehicle positions; Third, after a certain group finishes the repair, it is impossible to accurately know where this vehicle should be driven next, and it can only be judged by experience or driven to the re-inspection station for comprehensive judgment, increasing the flow distance, that is, the repair destination of the vehicle is unknown; Fourth, this system only enters problem points at the vehicle quality (Vehicle Quality, VQ) inspection post and marks it as completed when the vehicle quality inspection passes. There is no update for new problems and repair completion during the inspection process, resulting in the inability to determine the parking position of the vehicle during the vehicle flow process, causing the repair resources to be unable to be centrally arranged, that is, the repair process status cannot be monitored; Summary of the Invention

[0004] To solve the problems in the above-mentioned existing technologies, such as the inability to batch mark vehicles, difficult to find positions, unknown repair destinations, and inability to monitor the repair process status, resulting in low repair management efficiency, the present invention proposes a vehicle PDI repair intelligent management system and method, which can effectively batch mark vehicles, easily query vehicle position information in real time, realize automatic allocation of vehicle destinations, monitor the repair process status, and improve repair management efficiency.

[0046] The drawings are only for illustrative purposes and should not be construed as a limitation of this patent;

[0047] For those skilled in the art, it is understandable that some well-known content descriptions in the drawings may be omitted;

[0048] The technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0049] Embodiment 1

[0050] As Figure 2 shown, this embodiment proposes an intelligent management system for vehicle PDI repair, aiming to monitor the real-time location of PDI vehicles in the automobile factory, the quality problem points to be repaired, and the responsible departments, realizing the visualization of management indicators, thereby improving the vehicle delivery efficiency. The system includes:

[0051] An RFID vehicle tag for storing vehicle unique identification code information; among them, radio frequency identification, that is, radio frequency identification technology (RFID), is a type of automatic identification technology. It performs non-contact two-way data communication through radio frequency, and reads and writes the recording medium (electronic tag or radio frequency card) through radio frequency, so as to achieve the purpose of identifying the target and data exchange.

[0052] Refer to Figure 3 , the RFID vehicle tag is provided with a transceiver antenna, a demodulation circuit, a logic control circuit, a modulation circuit, a memory, and an AC / DC circuit;

[0053] The output end of the transceiver antenna is connected to the input end of the demodulation circuit, the output end of the demodulation circuit is connected to the first input end of the logic circuit, the second input end of the logic circuit is connected to the output end of the AC / DC circuit, the third input end of the logic circuit is connected to the output end of the memory, the output end of the logic circuit is connected to the input end of the modulation circuit, and the output end of the modulation circuit is connected to the input end of the transceiver antenna;

[0054] An RFID reader for reading the vehicle unique identification code information stored in the RFID vehicle tag and feeding back the vehicle unique identification code information and the location information of the RFID reader to the PDI repair intelligent system;

[0055] See Figure 4 , the RFID reader includes a radar, a controller, and an RFID antenna. The output end of the radar is connected to the input end of the controller. The controller is bidirectionally connected to the RFID antenna, and the controller is connected to an external power supply, which powers the controller; the RFID reader further includes traffic lights, and the input end of the traffic lights is connected to the output end of the controller; the controller controls the display of the traffic lights to indicate whether a vehicle can pass through the preset range of the radar in the RFID reader; wherein the RFID reader is installed at each parking lot entrance and exit, and at the entrance and exit of the workshop building. Each RFID reader is set with a unique number. See Figure 5 , the RFID reader is installed on a pillar. More specifically, the pillar is a Γ-shaped pillar, the radar and the antenna are installed on the top beam of the Γ-shaped pillar, and the controller and the traffic lights are respectively installed on the side beams of the Γ-shaped pillar;

[0056] The RFID reader reads the vehicle unique identification code information in the RFID vehicle tag, including:

[0057] When the radar detects that a vehicle is within the preset range, it transmits a detection signal to the controller. The controller receives the detection signal and activates the RFID antenna. The RFID antenna is used to send a first radio frequency signal to the RFID vehicle tag. The RFID vehicle tag receives the first radio frequency signal and converts the stored vehicle unique identification code information into a second radio frequency signal. The second radio frequency signal is transmitted to the controller through the RFID antenna. The controller converts the second radio frequency signal into an electrical signal for reading and writing to obtain the vehicle unique identification code information.

[0058] The signal receiving and transmitting principle of the RFID vehicle tag is:

[0059] The connection of the AC / DC circuit and the logic circuit provides the required DC power supply for the RFID tag to work; the receiving and transmitting antenna in the RFID vehicle tag receives the first radio frequency signal and transmits the first radio frequency signal to the demodulation circuit. The demodulation circuit receives the first radio frequency signal and demodulates the first radio frequency signal into an electrical signal and transmits it to the logic control circuit. The logic control circuit receives the electrical signal and converts the vehicle unique identification code information stored in the memory into a digital signal and transmits it to the modulation circuit. The modulation circuit modulates the digital signal into a second radio frequency signal and transmits it to the receiving and transmitting antenna. The receiving and transmitting antenna sends the second radio frequency signal to the RFID antenna.

[0060] The whole vehicle intelligent inspection management platform is used to query and record the problem points of vehicle quality when the vehicle passes through the RFID reader, allocate and guide the vehicle's destination according to the problem points, and share data with the PDI repair intelligent system; as a newly developed paperless quality inspection system based on RFID, the whole vehicle intelligent inspection management platform can realize that when the vehicle passes through a certain RFID point, the vehicle configuration content is automatically retrieved and displayed. Inspectors can directly mark the quality problem points on the whole vehicle intelligent inspection management platform to achieve data sharing. The whole vehicle intelligent inspection management platform can be used to record the quality problem points and responsible departments of each vehicle, query the repair completion and card cancellation status of each problem point of the vehicle in real time, and can also re-enter new defective problem points, connecting the whole vehicle intelligent inspection management platform with the PDI repair intelligent system to achieve data sharing;

[0061] See Figure 6 , the whole vehicle intelligent inspection management platform includes a defective entry module, a defective repair registration module, a defective reinspection confirmation module, and a repair station allocation and guidance module;

[0062] The defective entry module is used to query the problem points of vehicle quality defects and enter the problem points of vehicle quality defects; after the quality inspector checks, enter the problem points of vehicle quality defects. The problem points of vehicle quality defects can be queried by drop-down selection or keyword search to quickly enter the problems of vehicle quality defects.

[0063] The defective repair registration module is used to register the problem points of vehicle quality defects; in the defective repair registration module, the operator scans the vehicle number to obtain the problem points of vehicle quality defects in this field. After completing the repair of each problem point of vehicle quality defects, click the repair completion confirmation in the defective repair registration module.

[0064] The defective reinspection confirmation module is used to reinspect and confirm the problem points of vehicle quality defects; in the defective reinspection confirmation module, after the VQ reinspection personnel receive the vehicle, scan the vehicle number, and all the problem points of vehicle quality defects will pop up. Check each problem point that has been repaired on the actual vehicle one by one. Click confirm on the platform for OK, and click return for repair for NG.

[0065] The repair station allocation and guidance module is used to enter the corresponding responsible department according to the problem points of vehicle quality defects, and allocate and guide the vehicle to the repair station responsible by the responsible department for repair or reinspection and vehicle release; in the repair station allocation and guidance module, the destination of the vehicle that has passed through VQ is automatically allocated to guide the vehicle to flow to where to repair or reinspect and release the vehicle. After the vehicle enters the VQ CHECK point, the system will follow the set fixed process, combined with the responsible department entered for the defective problem points, allocate the repair station of the vehicle, and guide the vehicle's flow direction. This allocation and guidance is not mandatory, and can be manually allocated or the fixed process order can be adjusted.

[0066] The vehicle intelligent inspection management platform also includes a user login module. The user login module logs in to the personal account through a PAD adapted to the intranet, associates the corresponding function modules according to the position, and realizes position and permission identification.

[0067] The PDI repair intelligent system is used to receive the vehicle unique identification code information and the location information of the RFID reader, batch manage the PDI repair process of the vehicle, and transmit the PDI repair data to the main monitoring management platform.

[0068] See Figure 7 , the PDI repair intelligent system can be logged in and operated on the web page and the factory MES system, including a parallel basic data maintenance module and a business operation module. The basic data maintenance module and the business operation module are used to batch manage the PDI repair process of the vehicle, including:

[0069] Maintain the repair station sequence, vehicle location information, special vehicle parking guidance, vehicle quality in-stock reference number, departure rate number correction, and departure rate number correction through the basic data maintenance module;

[0070] In the basic data maintenance module, maintaining the repair station sequence specifically refers to adding or deleting stations and adjusting the allocation order;

[0071] Maintaining the vehicle location information specifically refers to adding or deleting RFID identification points and modifying the description of the existing repair stations;

[0072] Maintaining the special vehicle parking guidance specifically refers to manually adjusting the allocation of some batch defective or type vehicles to the designated parking area;

[0073] Maintaining the vehicle quality in-stock reference number specifically refers to setting the vehicle quantity reference for each area to identify the alarm over-standard and explosion-proof warehouse areas;

[0074] The departure rate number correction maintenance specifically refers to excluding and correcting the vehicles not included in the daily departure rate index; maintaining the parking area reference number specifically refers to adjusting the storage capacity reference of each area and displaying the remaining storage positions;

[0075] The business operation module is used for marking special delivery vehicles, counting the in-stock repair stations, counting the in-stock vehicle positions, online querying the problem point intervals of the vehicles, counting the responsible departments of the repaired vehicles, and querying the defective repaired vehicles.

[0076] In the business operation module, marking special delivery vehicles specifically refers to marking the delivery date requirements of special vehicles, marking the batch quality defect information, marking the batch missing parts information. After the repaired vehicles with batch defects or missing parts are completed, the repair status of the vehicles can be batch processed by importing the list according to the template;

[0077] The in - warehouse repair site statistics specifically refer to the statistics of the residence time of vehicles at a certain repair site (calculated from the completion of the previous repair site to the end at the next repair site). For vehicles with overdue time, the responsible department is reminded to reply with the delivery plan (pushed to relevant system personnel via enterprise WeChat);

[0078] The in - warehouse vehicle position statistics specifically refer to storing and statistically analyzing the real - time position information of vehicles. According to the latest position number of the vehicle returned by the RFID reader, the vehicle position is calculated in combination with the following set logic: When the vehicle first passes through a set of readers from the entrance, it is regarded as entering the production - stop site where the set of equipment is located, and the location information of the site is recorded; When the vehicle passes through the set of readers for the second time from the exit, it is regarded as moving out of the site, and the location information of the site is cleared; If the vehicle does not pass through the exit and directly passes through the readers of other sites, it is regarded as the vehicle entering other sites, the location information of the previous site is cleared, and the location information of the entered site is recorded;

[0079] The online query of vehicle problem - point intervals specifically refers to querying the positions, defective problem records, and repair completion status of all undelivered vehicles between two certain sites.

[0080] The statistics of the responsible departments for repaired vehicles specifically refer to statistically analyzing the total number of defective points, the number of repaired points completed, and the number of points to be repaired in each department according to vehicle models and responsible departments for defective problems, so as to guide the arrangement of repair resources;

[0081] The query of defective repaired vehicles specifically refers to querying the repair status of defective problem points for a specific vehicle, a specific derivative, a specific vehicle model, etc., which problem points have been repaired and which are to be repaired.

[0082] The main monitoring and management platform is used to monitor and manage the PDI repair data.

[0083] The main monitoring and management platform is a platform for guiding managers to conduct repair operations, including a comprehensive management display module and a repair control management display module. The PDI repair data is monitored and managed by using the comprehensive management display module and the repair control management display module, including: classifying and summarizing the PDI repair data to obtain a classification and summary result, and displaying the classification and summary result on the comprehensive management display module and the repair control management display module respectively;

[0084] The classification and summary result includes the vehicle delivery situation, vehicle position distribution map, in - warehouse statistics of each repair site, in - warehouse defective situation, and key vehicle delivery situation for display on the comprehensive management display module;

[0085] Among them, the vehicle delivery situation specifically refers to the number of vehicles in the warehouse, the number of vehicles delivered, the 8 - hour vehicle delivery rate on the current day, as well as the number of vehicles of each model in the warehouse, the number of returned vehicles, and the number of exceptional vehicles;

[0086] The vehicle location distribution map specifically shows the actual number of vehicles in each area. When the number exceeds the benchmark number, it will alarm with red flashing.

[0087] The in - warehouse statistics of each repair site specifically shows the number of vehicles at each site. When it exceeds the standard of this department, it will alarm with red flashing.

[0088] The in - warehouse defective situation specifically shows the number of vehicles to be repaired in each department currently, the number of vehicles with long storage age detained by each section chief, and the top 10 items of the current defective number.

[0089] The delivery situation of key vehicles specifically shows, for the vehicles marked as key, the number of vehicles that have expired and are about to expire in each department, and the details of the top 10 vehicles with the most urgent delivery dates.

[0090] It is used to display the achievement situation of VQ in - warehouse - repair site indicators, VQ long - storage - age vehicles, and VQ in - warehouse - vehicle location distribution situation in the repair control management display module. The achievement situation of VQ in - warehouse - repair site indicators is used to display the benchmark number, actual number, and achievement evaluation of each repair site. A ○ is marked within the benchmark, a × is marked when exceeding the benchmark, and the number of vehicles classified by vehicle type in each site.

[0091] The VQ long - storage - age vehicles is used to display the number of vehicles with long storage age in the responsible department of each repair, and set an indicator evaluation, which is divided into three sections. A ○ is marked when the detention duration N ≤ 6 days, a △ is marked when 7 days < N ≤ 13 days, and a × is marked when N > 14 days.

[0092] The VQ in - warehouse - vehicle location distribution situation is used to display the vehicle parking benchmark, actual parking number, beneficial - warehouse alarm, and the number of vehicles belonging to each site in each area.

[0093] Through the main monitoring and management platform, abnormal sites and storage areas can be quickly identified, so as to quickly dispatch resources and optimize vehicle parking and flow.

[0094] In this embodiment, a vehicle PDI repair intelligent management system is proposed. This system has the function of judging the vehicle position by reading vehicle information through RFID, has the function of automatically allocating the vehicle's destination guidance, has the function of inventory monitoring and alarm, has the function of warehouse location early warning management, and has the function of predicting the trend of production indicators. Further, the existing vehicle PDI repair intelligent management system has the following disadvantages: no vehicle position information, no vehicle flow destination guidance, no statistics and alarm for vehicles to be repaired, no statistics and early warning for warehouse locations, and no production indicator statistics function.

[0095] Compared with the existing vehicle PDI repair intelligent management system, the vehicle PDI repair intelligent management system proposed in this embodiment has the following advantages: an RFID reader reads the vehicle position area information; automatically assigns the next destination of the vehicle; can display the pending repair inventory of each repair department and alarm for departments exceeding the standard; when the storage capacity of the parking area exceeds the benchmark, gives an overstock reminder to newly parked vehicles; can predict the achievement of the monthly production target;

[0096] It should also be specifically stated that, firstly, by adopting RFID vehicle tags in this system, the RFID reader can quickly read and identify the unique vehicle identification code information of each vehicle, avoiding the drawback of unable to batch label vehicles, and significantly improving the vehicle identification and management efficiency; secondly, by installing RFID readers at each parking entrance and exit, when a vehicle with an RFID vehicle tag passes through the RFID reader, the vehicle position information can be obtained through the position information of the RFID reader, and the position information of the RFID reader is also real-time fed back to the repair intelligent system, enabling the management personnel to quickly locate the vehicle position information through the position information of the RFID reader, solving the problem of difficult vehicle location and enhancing the flexibility of vehicle scheduling and management; then, a set of rules for automatically assigning destinations is added to the vehicle intelligent inspection management platform. When a vehicle completes the operation at a certain station, the next destination to flow is automatically popped up. The vehicle intelligent inspection management platform intelligently assigns the vehicle destination according to the problem points of the vehicle quality, and through data sharing with the repair intelligent system, ensures that there is evidence to follow and the destination is clear for each repair operation of the vehicle destination, effectively avoiding chaos and delays in the repair process and improving the transparency of repair management; finally, the PDI repair intelligent system not only manages the repair process of vehicles in batches, but also can transmit the repair data to the main monitoring management platform for real-time monitoring. By statistically summarizing the underlying data of each vehicle, real-time inventory data is formed, and an alarm reminder is given when exceeding the benchmark. Then, combined with the subsequent plan trend, the future inventory and the achievement of the target are predicted and judged, ensuring that every detail in the repair process is accurately recorded and tracked, and any abnormality or delay can be discovered and processed in time, thus greatly improving the efficiency and quality of repair management.
