Description

Technical Field

[0001] This invention relates to the field of automotive production line management technology, specifically to a method, system, and storage medium for processing maintenance work orders on an automotive production line. Background Technology

[0002] Because automobile production lines involve complex processes, a wide variety of equipment, and collaborative operations, the process sections occupy a large area. Equipment failures can have a significant impact on production. Due to the close interrelationship between the equipment, it is difficult to quickly and accurately resolve faults by relying solely on the fault information output by the individual equipment itself. Most faults are reported manually, and then professional personnel make judgments and manually report the faults. This process delays the transmission of fault information and increases the time required to resolve the faults.

[0003] Alternatively, an information system management mechanism can be established by triggering work orders based on fault signals. For example, CN109862048A discloses a factory equipment processing system, equipment database server, and method. This system includes: a field operator terminal for receiving fault signals and information about the equipment to be repaired when a fault occurs; after receiving a repair request command input by the field operator, sending the fault signals and information to the equipment database server; and an equipment database server for generating a repair work order based on the fault signals and information; and generating a fault solution for the equipment to be repaired based on the fault signals and the relationship between the fault signals and fault solutions, and then sending the repair work order and the information about the equipment to be repaired to the relevant equipment. The fault solution is sent to the maintenance personnel's terminal. The maintenance personnel's terminal is used to display the maintenance work order and the fault solution for the equipment to be repaired. The processing method is as follows: when the equipment malfunctions, the system receives the fault signal and information of the equipment to be repaired; after receiving the repair request instruction input by the on-site operator, the system sends out the fault signal and information of the equipment to be repaired; the system receives the fault signal and information of the equipment to be repaired, and generates a maintenance work order based on the fault signal and information of the equipment to be repaired; the system generates a fault solution for the equipment to be repaired based on the fault signal and the relationship between the equipment fault signal and the fault solution, and sends out the maintenance work order and the fault solution for the equipment to be repaired; the system receives and displays the maintenance work order and the fault solution for the equipment to be repaired. However, due to the large number of fault signals involved in the production line equipment, the recovery of a fault signal does not necessarily mean that the equipment has returned to normal. There are repeated triggering situations when the equipment has not returned to normal, and often a chain of fault signals are triggered at the same time as one fault signal. This results in a large number of invalid and duplicate work orders being dispatched, increasing the management cost of work order processing. In order to reduce invalid work orders, the number of fault signals has been reduced, but this results in missing and inaccurate fault information. At the same time, this method cannot solve the problem of duplicate work orders, and the generated work order information is insufficient to guide the maintenance personnel's maintenance work, resulting in limited improvement in maintenance efficiency.

[0004] CN113516340A discloses a method, apparatus, computer device, and storage medium for pushing intelligent work orders. By acquiring work order information to be pushed, a pre-trained fault identification model is processed using the input values ​​of the work order information. Based on the processing result, the corresponding fault type is determined. Then, based on the correspondence between fault types and clients, a list of target clients corresponding to the fault types is obtained, and the intelligent work order information to be pushed is sent to the clients in the target client list. This method pushes work orders to selected clients, improving the efficiency and accuracy of work order information push and further enhancing the efficiency of fault response. It represents a valuable attempt in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a method, system, and storage medium for processing maintenance work orders on an automotive production line, which can effectively reduce the number of invalid and repetitive work orders on the production line, reduce information loss, and increase the effectiveness of maintenance guidance.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention discloses a method for processing maintenance work orders on an automobile production line, which includes task work order generation and task work order termination. The process of generating a task work order includes the following steps: S11, Divide the production line into multiple areas and number each area; preferably, divide the production line into multiple areas according to the principle of ensuring personal safety and the relationship between equipment and number each area, and classify the equipment that must stop at the same time when the equipment fails into the same area. S12, After the work order generation module obtains the fault information, it caches it in the storage module; S13, Traverse the fault information in the storage module, identify whether there is any unmarked fault information, if so, execute S14; otherwise, return to S12; S14, determine the area corresponding to the unmarked fault information, traverse the corresponding area in the storage module to see if there are any unfinished task orders, if yes, then execute S15; otherwise, execute S16. S15, record the fault information in the unfinished task work order to the dynamic information storage unit of the storage module and mark the fault information in the unfinished task work order, and mark the unfinished task work order. S16, the work order generation module generates a task work order based on the fault information obtained in S12, and marks the fault information obtained in S12; Furthermore, the completion of a task order includes the following steps: S21: The security integration signal of a certain area is obtained by the security integration signal generation module. If the security integration signal is the first set value, no operation is performed; if the security integration signal is the second set value, S22 is executed. S22 marks the task orders within the area as completed and clears the cached data.

[0007] Furthermore, in S21, the safety integrated signal is obtained by fitting the fault signal, drive enable signal, safety equipment signal, emergency stop signal, and equipment status signal of a certain area through the safety integrated signal generation module.

[0008] Furthermore, the fitting of the security integration signal for a certain area specifically includes the following steps: S31, acquire fault signals, analyze whether the acquired fault signal data are all the third set value. If yes, proceed to the next step; if no, reacquire the fault signals of the area and analyze the acquired fault signal data and output the safety integrated signal as the first set value. S32, acquire the drive enable signal, analyze whether the acquired drive enable signal data are all the fourth set value. If yes, proceed to the next step; if no, return to S31 and output the safety integration signal as the first set value. S33: Acquire safety device signals and analyze whether the collected safety device signal data are all the fifth set value. If yes, proceed to the next step; otherwise, return to S31 and output the safety integration signal as the first set value. S34, acquire emergency stop signal, analyze whether the acquired emergency stop signal data are all the sixth set value. If yes, proceed to the next step; if no, return to S31 and output the safety integrated signal as the first set value. S35: Acquire device status signals and analyze whether the collected device status signal data are all the seventh set value. If yes, proceed to the next step; otherwise, return to S31 and output the safety integration signal as the first set value. S36 outputs a safety integrated signal to the second set value.

[0009] Furthermore, the task order generated in S16 includes the location of the faulty equipment, fault code information, and the area number corresponding to the faulty equipment.

[0010] Furthermore, the task order generated in S16 is transmitted to the display module, which then displays the task order information.

[0011] Secondly, the present invention also discloses an automotive production line maintenance work order processing system, which can realize the automotive production line maintenance work order processing method described in the present invention. The system includes a work order generation module, a safety integrated signal generation module, and a storage module. The work order generation module is used to acquire fault information, parse and determine the region corresponding to the fault information, generate and / or terminate task work orders, and store dynamic work order information. The safety integrated signal generation module divides the production line into multiple regions and numbers each region, and obtains a safety integrated signal for a certain region based on the acquired signal fitting. The storage module is used to store the acquired fault information, the task work orders generated based on the acquired fault information, and dynamic information, i.e., fault information within unfinished task work orders.

[0012] Furthermore, the work order generation module includes a fault signal acquisition unit, a fault signal interface and equipment location relationship parsing unit, a fault information generation and caching unit, a region and equipment location relationship parsing unit, a safety integration information acquisition and caching unit, and a work order generation unit. The fault signal acquisition unit is used to acquire fault code information from the fault signal interface. The fault signal interface and equipment location relationship parsing unit is used to obtain the equipment location information corresponding to the fault signal interface. The fault information generation and caching unit is used to cache the fault code information and the equipment location information corresponding to the fault signal interface as fault information and transmit the fault information to the storage module. The region and equipment location relationship parsing unit is used to obtain the region number corresponding to the fault signal interface. The safety integration information acquisition and caching unit is used to acquire the safety integration signal output by the safety integration signal generation module. The work order generation unit is used to generate a maintenance task work order and transmit the task work order to the storage module.

[0013] Furthermore, the safety integrated signal generation module includes a fault signal acquisition unit, a drive enable signal acquisition unit, a safety equipment signal acquisition unit, an emergency stop signal acquisition unit, an equipment status signal acquisition unit, and a safety integrated signal generation unit. The fault signal acquisition unit is used to acquire fault signal data; the drive enable signal acquisition unit is used to acquire drive enable signal data; the safety equipment signal acquisition unit is used to acquire safety equipment signal data; the emergency stop signal acquisition unit is used to acquire emergency stop signals; the equipment status signal acquisition unit is used to acquire equipment status signals; and the safety integrated signal generation unit is used to receive the acquired fault signals, drive enable signals, safety equipment signals, emergency stop signals, and equipment status signals, fit them to obtain a safety integrated signal, and transmit the safety integrated signal to the work order generation module.

[0014] Furthermore, the storage module includes a fault signal interface and equipment location relationship storage unit, a region and equipment location relationship storage unit, a safety integrated signal interface and region relationship storage unit, a work order information storage unit, and a dynamic information storage unit. The fault signal interface and equipment location relationship storage unit stores the correspondence between fault signal interfaces and equipment locations. The region and equipment location relationship storage unit stores the correspondence between region numbers and equipment locations. The safety integrated signal interface and region relationship storage unit stores the correspondence between safety integrated signals and region numbers. The work order information storage unit stores task work order information. The dynamic information storage unit stores process fault information and status information generated during maintenance.

[0015] Furthermore, it also includes a display module, which is used to display task work order information.

[0016] Furthermore, the display module includes a work order information display unit and a dynamic information display unit connected to the work order generation module. The work order information display unit displays task work order information, including the location of the faulty equipment, fault code information, and the area number corresponding to the faulty equipment. The dynamic information display unit displays process fault information and status information generated during maintenance.

[0017] Thirdly, the present invention also discloses a storage medium storing a computer-readable program, which, when invoked, can execute the steps of the automobile production line maintenance work order processing method described in the present invention.

[0018] The beneficial effects of this invention are as follows: This invention acquires fault information and caches it in the storage module. First, it iterates through the fault information in the storage module to identify any unmarked fault information. That is, it first confirms whether there is any unprocessed fault information in the storage module. If there is no unprocessed fault information, the next loop begins. If there is unprocessed fault information, it determines the region corresponding to the unmarked fault information and iterates through the corresponding region in the storage module to check for any unfinished task orders. If there are unfinished task orders, the fault information within these unfinished task orders is recorded in the dynamic information storage unit of the storage module and marked. This separates task order generation from dynamic fault information and marks unfinished task orders for easy later review. If there are no unfinished task orders, task orders are automatically generated based on the acquired fault information. When a task order ends, the safety integration signal generation module acquires the safety integration signal for a certain region. If the safety integration signal is a first preset value, no operation is performed; if the safety integration signal is a second preset value, the task order within that region is marked as finished, and the cached data is cleared. By integrating security signals to isolate subsequent invalid and duplicate work orders, the number of invalid and duplicate work orders is effectively reduced. Furthermore, by storing dynamic work order information, information loss is reduced, thereby increasing the effectiveness of maintenance guidance. Attached Figure Description

In this embodiment, the sixth preset value is set to "false". If yes, that is, the acquired safety equipment signal data are all false, then the next step is executed; if no, that is, the acquired safety equipment signal data are not all false, then return to S31 and the safety integrated signal is output as the first preset value through the safety integrated signal generation unit 25.

In this embodiment, the seventh set value is set to "true". If yes, that is, the acquired device status signal data are all true, then the next step is executed; if no, that is, the acquired device status signal data are not all true, then return to S31 and the safety integration signal is output by the safety integration signal generation unit 25 as the first set value.
