Description

The present invention relates to an inspection management system used for inspecting desired inspection objects such as automobiles manufactured in an automobile factory.

An inspection management system of this type is disclosed in Patent Document 1, for example.
The inspection management system described in the document includes an inspection terminal (communication terminal) carried by an inspector who inspects an automobile manufactured in an automobile factory. This inspection terminal can display inspection items to be inspected by the inspector on the screen, and the inspector proceeds with the inspection according to this display. Therefore, it is possible to prevent inspection omissions.
In addition, the inspection management system described above is also equipped with a repair terminal. This repair terminal can display the inspection items on the screen when there is a defect as a result of the inspection by the inspector and it is necessary to repair (repair) it. This inspection terminal is used in the automobile repair work process, and is useful for smooth work.

However, the prior art has room for improvement as described below.

In other words, it is desirable to inspect whether or not the repairs have been performed appropriately after the inspection of the vehicle to be inspected indicates that there is a defect and the repairs have been performed. However, the above-mentioned conventional terminal for repair only displays the items for repair on the screen to be used in the repair work process, and is used for inspection after repair and input of inspection results. It has become difficult to use. On the other hand, the above-described conventional inspection terminal is capable of inputting inspection result data relating to a plurality of inspection items, but is not suitable for inspection after repair. Even if the inspection terminal is used for inspection after rework, it would be difficult to determine whether or not the data of the inspection result has undergone the rework. From various perspectives, such as increasing the productivity of the inspection target by verifying the inspection results to find out what kind of inspection items frequently have defects, and by improving the production process, As for the data, it is desired to be able to accurately determine whether or not the product has been reworked. On the other hand, the prior art described above cannot adequately meet such demands.

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

The inspection management system SY shown in FIG. 1 is installed as a final line in an automobile factory and applied to an inspection line L for inspecting automobiles 5 . The inspection line L includes an adjustment line and an instrument line for sequentially inspecting a plurality of predetermined inspection items, and a final inspection line is provided at the most downstream position.

This inspection management system SY includes, as its constituent devices, a plurality of communication terminals 1 for operation by a plurality of inspectors, an information management terminal 2 installed in a management office in a factory or near an inspection line L, and One or a plurality of large-sized displays 3 (called "andon") are installed at locations where each inspector can easily see the inspection line L. The display 3 is appropriately provided with a lamp 30 to be turned on in an emergency, an acoustic device 31 for generating an alarm sound, and the like.

The communication terminal 1 is a terminal for an inspector to operate on the inspection line L, and is a mobile terminal such as a smart phone or a tablet terminal, and has a program installed therein for performing data processing, which will be described later. . In FIG. 1, a communication terminal 1 (1a) as a smart phone that can be worn on the arm by an inspector using a belt, and a communication terminal 1 (1b) as a tablet terminal arranged near the inspection line L. Two types are shown. The communication terminal 1 may be any of these, or may be used in a mixed state.
A wireless LAN system is constructed in the inspection line L, and wireless communication is possible between the communication terminal 1 and the information management terminal 2 . A wireless LAN system is, for example, a Wi-Fi network system.

As shown in FIG. 2A, the communication terminal 1 includes a data processing unit 10 configured using a CPU or the like, a communication circuit 11 capable of wireless communication such as Wi-Fi, and a storage unit having a ROM, a RAM, and the like. 12, a display unit 13 using a liquid crystal display or the like, an operation unit 14, an imaging camera 15, and a speaker 16, which are connected to each other via a bus. The operation unit 14 employs a touch panel system and is combined with the display unit 13 .

The storage unit 12 stores inspection program data Da for proceeding with the inspection of the automobile 5 . Preferably, inspector authentication program data Db for authentication of an inspector who operates the communication terminal 1 is also stored.
The communication terminal 1 cannot be used for inspection unconditionally. It is a requirement that a login state with a communication connection is established. In this embodiment, as will be described later, valid access (login state) of the communication terminal 1 is permitted by transmitting imaging data for face authentication of the inspector from the communication terminal 1 to the information management terminal 2. It has become so. The inspector authentication program data Db is program data for executing data processing for such face authentication.
The program data Da and Db described above can be appropriately downloaded from the information management terminal 2 or a host computer (not shown) installed separately from the information management terminal 2 for managing data in the entire factory.

The information management terminal 2 is configured using a personal computer, for example, and its basic hardware configuration itself is the same as that of the communication terminal 1 except that the imaging camera 15 is not provided. Specifically, as shown in FIG. 2B, the information management terminal 2 includes a data processing unit 20, a communication circuit 21, a storage unit 22, a display unit 23, an operation unit 24, and a speaker 25. there is As will be described later, the information management terminal 2 can receive data relating to inspection results from the communication terminal 1, store them in the storage unit 22, and complete inspection report C (see FIG. 1) showing the inspection results of the automobile 5. can be printed out using the printer 26 . The information management terminal 2 also drives the display 3, the lamp 30, and the sound device 31 to display predetermined information, such as the display of the inspector who performs the inspection work on the inspection line L, and to report an abnormality. It also has functions.

Installed in the storage unit 22 are data Dc regarding inspectors, data Dd of inspection item lists, and data De for creating inspection items after repair.
Here, the data Dc regarding inspectors includes, for example, the names, employee numbers, and face authentication data of each of a plurality of inspectors. Various inspections in the inspection line L include those that require certain qualifications (e.g., automobile inspector qualification) and those that do not. It also includes data such as the existence and content of qualifications, attendance history of automobile inspector training, and years of practical experience.
Such data Dc relating to the inspector is transmitted from, for example, the above-described host computer, and its contents are updated as appropriate. However, in order to prevent the content of data from being illegally rewritten, only a limited number of persons with certain responsibilities and authorities are allowed to rewrite the data Dc.

The inspection item list data Dd is data in which items to be inspected in the inspection of the automobile 5 are listed, and the contents thereof differ according to the vehicle type. This inspection item list data Db is transmitted to a plurality of communication terminals 1, and in these communication terminals 1, is converted into process-specific inspection item data to be executed in a plurality of inspection processes in the inspection line L, and each The content suitable for the inspection process is displayed on the screen.

The post-repair inspection item creation data De is created as a post-repair inspection item when there is an inspection item that is determined to be defective in the inspection of the automobile 5 and has undergone the repair (correction). , are program data for distinguishing from other inspection items. In the inspection of the automobile 5, there is a defect, and after the repair is made, it is necessary to inspect whether the defect has been properly resolved. This data is also transmitted from the information management terminal 2 to the communication terminal 1 . In the communication terminal 1, it is possible to perform the inspection by displaying the inspection items after the repair on the screen under predetermined conditions described later, and to input the inspection result data.

Next, an example of the operation processing procedure in the inspection management system SY will be described with reference to the flow charts shown in FIGS. 3 and 4. FIG.

First, for example, on the startup screen of the communication terminal 1, an icon for selecting inspection of the automobile 5 is displayed. When the inspector touches the icon, selects to inspect the automobile 5, and performs an authentication operation for confirming who the inspector is, the data corresponding to this operation is sent to the information management terminal. 2 (S1: YES, S2: YES, S3). The authentication operation is an operation for face authentication. Specifically, the inspector uses the imaging camera 15 of the communication terminal 1 to capture an image of his or her own face. When the imaging is completed, the imaging data is transmitted to the information management terminal 2 under the control of the data processing section 10 .

On the other hand, the information management terminal 2 judges whether or not the inspector is a valid inspector, transmits the judgment result to the communication terminal 1, and recognizes that the inspector is valid. In this case, the data of the inspection items that this inspector can take charge of are also transmitted to the communication terminal 1 (S51). These data are stored in the storage unit 22 of the information management terminal 2 . In determining whether or not the inspector is a legitimate inspector, the identity of the inspector is specified based on the imaging data for face authentication received from the communication terminal 1, and then stored in the storage unit 22. It is determined whether or not the specified inspector is a valid inspector by referring to the stored data Dc regarding the inspector. For example, a person not included in the inspector list of data Dc (unregistered person) is not recognized as a legitimate inspector.

If the result of the judgment in the information management terminal 2 is that the inspector is not valid, and data to that effect is transmitted to the communication terminal 1, the inspector is in charge at the communication terminal 1. A screen is displayed indicating that there is no inspection that can be performed or that the inspector is not authorized (S4: NO, S13). In this case, the communication terminal 1 is in a state in which it is not possible to input data regarding examinations. Therefore, if the inspector is not a valid inspector, it is appropriately prevented from proceeding with the inspection of the automobile 5 using the communication terminal 1 .

On the other hand, unlike the above, if the result of the judgment is that the inspector is legitimate, the communication terminal 1 is in a logged-in state in which communication is connected to the information management terminal 2, and its display section 13 shows: A screen is displayed for the inspector to proceed with the predetermined inspection, that is, data of inspection items that the inspector can take charge of is displayed (S4: YES, S5).
The screen display of the communication terminal 1 is, for example, as shown in FIG. 5, in which an image Ia of inspection items, an image Ib showing information about an inspector, and the like are displayed. The image Ib is for allowing the inspector to confirm his/her own information.

When one of the inspection item images Ia described above is selected by tapping, the display is switched to a screen display for proceeding with the inspection. This screen display shows, for example, an image as shown in FIG. 6, and includes a plurality of inspection item display columns C2, an inspection result entry column C3, and the like, in addition to an inspector's signature column C1. There is also a vehicle information display column C4 for identifying the vehicle 5 to be inspected. Vehicle information is obtained by imaging a two-dimensional barcode (for example, QR code (registered trademark)) of an inspection specification 50 attached to each automobile 5 (see FIG. 1) using the imaging camera 15 of the communication terminal 1. It can be read by doing

The inspection of the vehicle 5 is carried out by reading the above-described vehicle information of the vehicle 5 into the communication terminal 1, and entering data indicating whether or not there is a defect for each inspection item in the inspection result entry column C3 (S6). . Data input as to whether or not there is a defect can be performed by tapping, for example, the display portion of the desired inspection item in the inspection item display field C2. It is also possible to enter the contents in the test result entry field C3 by handwriting. If there is a problem, it is necessary to make repairs and reinspect before sending the automobile 5 to the final inspection. (S7: YES, S8). Furthermore, a selection process is performed to determine whether or not line inspection is necessary again (S9). These processes are performed by an inspector operating the communication terminal 1, for example. It can also be configured to run automatically by 10.

As the inspection proceeds as described above, the data is recorded in the communication terminal 1 each time inspection result data is entered (S10). When all inspections for the inspection items in charge are completed, the inspection result data is transmitted to the information management terminal 2 (S11: YES, S12), and then the communication terminal 1 is logged out.
Although omitted in the flow chart, the transmission of inspection result data is, for example, on the condition that the authentication operation (imaging operation for face authentication) for confirming that the inspector is a valid inspector is performed again. It can be configured to run

In response, the information management terminal 2 records the test result data transmitted from the communication terminal 1 (S52). The inspection result data is transmitted from the communication terminal 1 used by each of the inspectors on the inspection line L to the information management terminal 2, so based on these data, the inspection results for all of the inspection items can be obtained. It is possible to create data for the filled-in completion inspection report C and output it using the printer 26 or the like.

However, the inspection result data may include an inspection item that is determined to be defective. In this case, the department in charge of the manufacturing line corresponding to the inspection item is requested to correct the defect. An instruction to the effect is given (S53). This instruction is preferably performed by automatically transmitting data from the information management terminal 2 to an information processing device (not shown) managed by the department in charge, but is not limited to this, and various means may be used. It is possible to adopt.
If there is a report to the effect that the repair has been completed in response to the instruction to the department in charge, that effect is recorded in the information management terminal 2 (S54). In this case, related information such as the name of the person in charge of repair and the method of repair is also recorded in the information management terminal 2 .

The communication terminal 1 can be used as an inspection terminal after repair. This point will be described below.

First, the communication terminal 1 is capable of a selection operation to perform an inspection after repair. When this operation is performed and vehicle information specifying the vehicle to be inspected is input, these data are transmitted to the information management terminal 2 (S21: YES, S22: YES, S23). As a prerequisite for these operations, a configuration may be adopted in which face authentication of the inspector or the like is required.

When the information management terminal 2 receives the above data, it reads the information about the current inspection of the vehicle 5 to be inspected from the repaired inspection item creation data De in the storage unit 22 and transmits it to the communication terminal 1 . When such a response is received, the communication terminal 1 enters a login state and stores the information transmitted from the information management terminal 2 (S24).

When a predetermined operation is performed on the communication terminal 1 in the above-described state, a screen display indicating the item of the problem and the presence/absence of repair is performed (S25: YES, S26).
This screen display is, for example, as shown in FIG. 7(a). Specifically, in addition to the vehicle information display column C4, a display column C5 for inspection items determined to be defective in the previous inspection is displayed. contains. In the display column C5 in the same figure, "head lamp" and "hazard lamp" are listed as examples of inspection items (parts) determined to be defective, and their parts (positions), defect phenomena (details) are listed. ), and whether or not the inspection after rework has been completed is shown.
Preferably, when one of the items in the display column C5 is tapped and selected, the route (history) related to this selected item is displayed. FIG. 7(b) shows an example when the hazard lamp item in FIG. 7(a) is selected. It is configured to display the name of the person in charge of the initial inspection, the name of the person who performed the rework, and the like. After completing the inspection after the repair, which will be described later, the name of the person in charge of the inspection after the repair is displayed, for example, as indicated by reference numeral Na in FIG. 7(c).

Although illustration and explanation are omitted, the communication terminal 1 can input the data of the inspection result when the inspection item for which the defect has been repaired and the inspection after the repair has not yet been performed is inspected. It is said that Each time such an inspection after repair is performed, the inspection result is recorded in the communication terminal 1 (S27: YES, S28). When the inspection after the repair is completed and, for example, the inspector performs face authentication, the data of the inspection result after the repair is sent to the information management terminal 2 (S29: YES, S30). After that, the communication terminal 1 is in a logout state.

On the other hand, in the information management terminal 2, the inspection result data after the repair transmitted from the communication terminal 1 is recorded in association with other inspection result data, such as being integrated (S62). This updates the information regarding the inspection of the vehicle 5 . If it is determined that the defect has not been properly resolved in the inspection result after the repair, the department in charge is instructed to perform the repair again (S63).

In this inspection management system SY, the two-dimensional code of the inspection specification 50 of the vehicle 5 is read by the communication terminal 1 to specify the vehicle 5 to be inspected. It is possible to cause the communication terminal 1 to appropriately transmit information regarding the inspection of the automobile 5 . As a result, the communication terminal 1 can display the defect list of the automobile 5 on the screen, for example, in the manner shown in FIG. 8(a). In the screen display shown in the figure, in addition to the vehicle information display column C4, a display column C6 indicating whether or not inspection of all inspection items for the automobile 5 has been completed (whether there are any omissions), and a display column C6 after repair. There are a display column C7 for indicating whether or not there is any remaining inspection (omission), and a display column C8 for indicating the name of the inspection process in which the defect was detected, the number of defects, and the like. In FIG. 8A, the display column C7 indicates that the inspection after the repair has not been completed, but the inspection after the repair has been performed without omission, and all defects have been resolved. If it is determined that there are no leftovers (omissions) in the post-repair inspection, the display column C7 displays that the post-repair inspection is complete, as shown in FIG. 8B, for example. . When there is no remaining (omission) in the inspection after the repair, the setting for canceling the final inspection on the inspection line L set in step S8 is canceled.

The vehicle 5 to be inspected is finally sent to the inspection line L for the final inspection process. In this final inspection process, whether or not all the inspections of the automobile 5 have been properly completed is checked by displaying the defect list screens shown in FIGS. 8A and 8B on the communication terminal 1. can be easily and quickly confirmed. Further, by performing a predetermined operation on the communication terminal 1, it is possible to display the screen as shown in FIG. 7(c) as appropriate. Also convenient.

The invention is not limited to the content of the embodiments described above. The specific configuration of each part of the inspection management system according to the present invention can be modified in various ways within the intended scope of the present invention.

The "communication terminal" as used in the present invention has, as its basic function, a display of a plurality of predetermined inspection items relating to an inspection object, and a failure detection for each of the plurality of inspection items as inspection result data relating to the inspection object. Data indicating the presence or absence or data corresponding thereto may be input. Here, "corresponding data" corresponds to data indirectly indicating the presence or absence of a defect, not data directly indicating the presence or absence of a defect.
In addition, the "communication terminal" can be used as a terminal for inspection after rework. The specific input method of the resulting data is not limited.
The "communication terminal" is preferably a portable terminal such as a smart phone or a tablet terminal, but alternatively or additionally, a small notebook computer or the like may be used. Similarly, the specific type of information management terminal is not limited, and various information processing apparatuses can be used as the information management terminal of the present invention.

In the above-described embodiment, the inspector is configured to undergo face authentication as a precondition for appropriately proceeding with the inspection using the communication terminal 1. However, as a method for the inspector to undergo authentication, Biometric authentication other than face authentication (for example, authentication using fingerprints, irises, veins, palms, voiceprints, auricles, etc.) can also be adopted. In addition, it is determined whether an inspector is a legitimate inspector by means other than biometric authentication (means using a password known only to a legitimate inspector, or simply entering the inspector's name or ID). It can also be configured to However, in the present invention, it is possible to omit such a thing.

The "inspection object" as used in the present invention is not limited to automobiles, and can, of course, be inspection objects for vehicles other than automobiles, and can also be inspection objects for various other products.
