Further, the production management system 4 is further configured to, after performing an alarm on an assembly station corresponding to the primary reason point, prompt an incorrect unique part number + version number and a correct unique part number + version number on a display screen of a corresponding assembly station, slow down a production line running speed, and wait for a worker to make a decision: i.e. stop the production line or replace the correct part.
In the normal part assembling link, the image recognition device 3 is used for recording and recognizing part installation actions and part installation completion states of workers at each assembling station and feeding the part installation actions and the part installation completion states back to the production management system 4.
The production management system 4 is further configured to perform secondary comparison on the part installation actions and the part installation completion states of the workers at each assembly station and the part installation actions and the part installation completion states set by the system for each assembly station in sequence, and if any one secondary comparison result is inconsistent, display a secondary reason point with the inconsistent any one secondary comparison result on a display screen of the corresponding assembly station and the production management system 4, and perform assembly station alarm corresponding to the secondary reason point; and if all the secondary comparison results are consistent, entering a vehicle offline detection link. For example, the secondary points of cause include, but are not limited to, forgetting to torque the fastener with a torque setting tool or two part-match clearances not meeting set values. For example, when the secondary reason point is that a torque of a fastener is fixed by forgetting using a torque fixing tool, the alarm of the assembly station corresponding to the secondary reason point is executed as follows: and executing an assembly station corresponding to the secondary reason point to perform torque-fixing alarm on the fastener by using a torque-fixing tool. For another example, when the two part matching gaps do not satisfy the set value, the assembly station corresponding to the two part matching gaps is set as: and executing alarm of overlarge matching gap between two parts of the assembly station corresponding to the secondary reason point. Further, the production management system 4 is further configured to slow down the operation speed of the production line after performing the alarm of the assembly station corresponding to the secondary reason point, and wait for a worker to make a decision: namely stopping the production line, emergently making up errors or performing off-line post-treatment.
In the vehicle offline detection link, if the vehicle function is detected to be abnormal, the production management system 4 is also used for calling and analyzing a record file in the production management system 4 during part assembly according to the input vehicle identification code to determine whether the production is abnormal, and if the part assembly is not standard, the part is reassembled according to the assembly requirement; if the quality of the parts is abnormal, the enterprise resource management system 2 is used for tracing the ex-warehouse time and the inventory of the parts with abnormal quality, and the production management system 4 is also used for tracing the vehicles assembled by the parts with abnormal quality which are ex-warehouse; if the production is normal, the data management system 5 is used for calling out parts of the vehicle and judging whether part design problems exist or not, if the part design problems exist, the production management system 4 is also used for searching the vehicles with which vehicle identification codes the parts with the design problems are assembled on, and the enterprise resource management system 2 is also used for searching the inventory of the parts with the design problems and finishing the tracing.
Or, in the vehicle offline detection link, if the vehicle function is detected to be normal, selling the vehicle through a 4S store or a market, and if there is an after-sale problem after selling the vehicle, the production management system 4 is further configured to call and analyze a record file during component assembly in the production management system 4 according to the input vehicle identification code to determine whether production is abnormal, and if the component assembly is not standard, reassembling the component according to the assembly requirement; if the quality of the parts is abnormal, the enterprise resource management system 2 is used for tracing the ex-warehouse time and the inventory of the parts with abnormal quality, and the production management system 4 is also used for tracing the vehicles assembled by the parts with abnormal quality which are ex-warehouse; if the production is normal, the data management system 5 is used for calling out parts of the vehicle and judging whether part design problems exist or not, if the part design problems exist, the production management system is also used for searching the vehicles with which vehicle identification codes the parts with the design problems are assembled on, and the enterprise resource management system is also used for searching the inventory of the parts with the design problems and finishing the tracing.
