JP 2001-268202 A Japanese Patent Application No. 5-332794

  Conventionally, when inspecting the display screen transition and display contents in the navigation device, it is inspected whether or not a screen (reference screen) expected when a specific switch is operated is displayed. In this case, a reference screen for the display screen corresponding to the operation of the operation switch must be created and stored. A large number of reference screens are required according to the order of operation of each operation switch. For example, a reference screen exceeding 30000 screens is required, and a storage unit having a large storage capacity is required as a data storage unit. In addition, the reference screen has a substantial amount while confirming the operation switch operation procedure designed at the beginning of development, the order of screen transitions related to this operation procedure, and the display screen contents for each screen change. Must be created and is extremely troublesome. In particular, at the beginning of development, there are many design changes (screen transition order change and screen display content change), and each time the reference screen is tediously changed.

  In addition, in the conventional display inspection system, it is possible to inspect a specific display screen instead of inspecting the entire display screen. In this case, a reference screen corresponding to the display screen to be inspected is created. . However, there is also a problem that when there is a defective screen on the way until the display screen to be inspected appears, there is no reference screen corresponding to the screen and it cannot be detected. In this case, a reference screen is created by predicting that a problem will occur, but it is difficult to predict which screen will cause a problem.

  The present invention has been made in view of the above circumstances, and its purpose is that it is not necessary to create a troublesome reference screen, no storage means for storing the reference screen is required, and any screen at any operation stage is arbitrary. It is an object of the present invention to provide a display inspection system that can be inspected.

  According to the invention of claim 1, a plurality of electric devices are arranged side by side by the arranging means, and a plurality of operation switches of the same kind of the plurality of electric devices are pressed and operated almost simultaneously in a predetermined order by the switch operating means. The means acquires the display image of the display device of each electric device every time the operation switch of the electric device is operated, and compares the acquired display images to inspect the transition and display contents of each display screen. From the above, if the transition patterns of the display images of a plurality of electrical devices match and the display contents match, it can be determined that the display transitions and display contents of both electrical devices are normal, and if they do not match, either It can be determined that there is an abnormality in the electrical equipment.

  Thus, according to the invention of claim 1, since the display screen transition and the display content can be inspected by the coincidence / non-coincidence of the display screens of a plurality of electric devices, it is not necessary to create a reference screen for each operation of the operation switch. In addition, it is possible to eliminate the trouble of creating the reference screen, no storage means for storing the reference screen is required, and any screen at any operation stage can be inspected arbitrarily.

  In this case, the switch operating means may be configured to include a pressing member configured to include fingers having the same interval as the arrangement interval of the plurality of electric devices, and an actuator that operates the pressing member. Invention of 2). In this way, the same kind of operation switches of a plurality of electric devices can be pushed in synchronism without making a mistake.

  In this case, the actuator may be a robot (invention of claim 3). In this way, the plurality of operation switches can be pushed well in a predetermined order, and even if the operation order is changed, the change can be quickly handled.

  Moreover, it is good also as a structure provided with two or more attachment parts for attaching the said finger selectively to the said pressing member (invention of Claim 4). If it does in this way, while being able to change the attachment position of a finger, a plurality of fingers of different forms, such as a finger for horizontal pushing and a finger for vertical pushing, can be attached, and it can respond to various pushing operation forms. .

  Further, the electric device to be inspected may be a car navigation device (invention of claim 5). Although the car navigation device has a large number of display screen transitions and the display inspection is considerably troublesome, the car navigation device can easily and simply perform the display inspection of the car navigation device.

  A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an overall schematic configuration of the display inspection system 1.

The base plate 13 is attached to an appropriate support base (not shown). As shown in FIGS. 3 and 5, the two navigation devices 2A and 2B are arranged at a predetermined arrangement interval P, for example. A large number of screw insertion holes 13a and 13b are formed in a predetermined arrangement on both sides of the arrangement centers 13c and 13c, respectively.

  As shown in FIG. 3, the holding plate 14 is used to hold the navigation devices 2A and 2B from above, and has a predetermined arrangement (the screw insertion holes 13a) on both sides of the arrangement centers 14c and 14c of the navigation devices 2A and 2B. , 13b), a large number of screw insertion holes 14a, 14b are formed.

  The two navigation devices 2A and 2B are arranged on the base plate 13 and are held by the holding plates 14 and 14, and the long screw 15 is inserted into appropriate screw insertion holes 13a, 13b, 14a and 14b. By being inserted and tightened with nuts, they are arranged in a fixed state in the same direction.

  The robot 6 corresponds to an actuator, and is composed of a 6-axis robot. A push member 16 is attached to the tip flange. As shown in FIGS. 3, 6, and 7, the pressing member 16 has a horizontal portion 16 a, one columnar portion 16 b, and the other columnar portion 16 c continuously, and has a substantially U shape as a whole. . The interval between the one columnar portion 16b and the other columnar portion 16c is set to be equal to the arrangement interval of the navigation devices 2A and 2B.

  A plurality of mounting holes 17a and 17b corresponding to mounting portions are formed in the horizontal portion 16a, one columnar portion 16b, and the other columnar portion 16c. The mounting holes 17a and 17b have different diameters so that they can be mounted satisfactorily even if the diameter of the mounted portion 18a of the fingers 18A and 18B described later is changed. Further, a screw insertion hole portion 16d for connection with a flange and a positioning portion 16e are formed in the central portion of the horizontal portion 16a.

  The attached portions 18a of the fingers 18A and 18B are detachably inserted and attached to the mounting holes 17a and 17a at the uppermost position of the one columnar portion 16b and the other columnar portion 16c of the pressing member 16, for example. As shown in FIGS. 6B and 7, the fingers 18 </ b> A and 18 </ b> B are configured by inserting and arranging a root portion of the push rod portion 18 b in a cylindrical attached portion 18 a. A spring (not shown) for biasing the push rod portion 18b in the pushing direction is provided inside the attached portion 18a. The push rod portion 18b is made of an elastic member such as an elastomer.

The robot 6 and the pushing member 16 constitute a switch operating device 19 serving as a switch operating means.
The camera 7 captures a front image of the navigation device 2A to obtain switch coordinates. In this case, the camera 7 images the navigation device 2A so that the push member 16 does not enter the camera frame of the camera 7. . An image captured by the camera 7 is input to the system control device 9. In this case, since the navigation device 2A and the navigation device 2B have the same configuration, the navigation device 2B may be imaged.

  The image capturing devices 8A and 8B steal video signal lines connected to the display device 3 from the drawing units in the navigation devices 2A and 2B, and chapter the images. Controlled by.

  The system control device 9 is composed of a computer, and is composed of a computer main body 9a, a display 9b, and a keyboard (operation unit) 9c. As is well known, the computer main body 9a includes a CPU, a ROM, a RAM, a mass storage device (for example, a hard disk drive), etc., which are not shown. The system control device 9 corresponds to inspection means.

The robot control interface 10 is a communication interface between the system controller 9 and the robot controller 11.
The teaching pendant 12 teaches (sets) the target position to which the robot's hand (tool such as a hand) moves, and moves by inputting each operation in turn or creating the operation sequence as a program. Can be operated. The robot 6 can be operated independently by the robot controller 11 and the teaching pendant 12.

Now, the display inspection operation in the above-described display inspection system 1 will be described.
[Step 1]
The system control device 9 first operates the camera 7 to image the navigation device 2A. This captured image is captured by the system control device 9 and displayed on the display 9b as coordinates (see FIG. 8). On the coordinate screen D displayed on the display 9b, the coordinate ranges Za to Zh of the operation switches 4a to 4h are designated, and the switch types and switch arrangement positions of the operation switches 4a to 4h are defined by the coordinate ranges Za to Zh. .

[Step 2]
Next, each operation switch defined in step 1 is associated with the same operation switch position of the navigation devices 2A and 2B to be inspected. This association is an association for causing the robot 6 to press the corresponding operation switch when the switch position (coordinate range Za to Zh) of the camera image captured in the display 9b shape is clicked with the mouse in the next step 3. is there. At this time, the teaching pendant 12 is used to set the direction and movement method of the robot 6.

[Step 3]
An operator inputs an arbitrary switch operation procedure for inspection to the system controller 9. At this time, when the switch position (coordinate range Za to Zh) of the camera image on the display 9b is clicked by the above-mentioned arbitrary procedure, the switch operation procedure is created and stored. Each clicked switch position is associated with the operation of the robot 6 pressing the target operation switch as described above.

[Step 4]
When an inspection start command is input to the system control device 9, the system control device 9 issues a switch operation command to the robot 6 via the robot control interface 10 according to the switch operation procedure created in step 3. Thereby, the robot 6 pushes the same type of target switches among the operation switches 4a to 4h of the navigation devices 2A and 2B by the fingers 18A and 18B of the push member 16. Thereby, the display screens of the display devices 3 of the car navigation devices 2A and 2B transition. At the timing after this transition, the system control device 9 gives a steal command to the image capturing devices 8A and 8B. The image capturing devices 8A and 8B steal the video signal lines, chapter the images, and the system control device 9 To enter.

  The system control device 9 performs image processing (for example, edge processing) on both input images, compares both processed images, and determines (inspects) whether or not they are the same screen. This determination is performed for each operation of the operation switch. If the contents of both screens are the same every time the screen is switched (screen switching), the screen transition is normal and the screen content is also normal. The determination result is stored in a mass storage device provided in the system control device 9. Since the two screens are compared in this way, the system control device 9 does not require a reference screen.

  In the display inspection system 1 of this embodiment, the navigation devices 2A and 2B are arranged side by side by the navigation arrangement device 5, and a plurality of operation switches of the same kind of the plurality of navigation devices 2A and 2B are arranged by the switch operation device 19. Are pressed almost simultaneously in a predetermined order, and each time the operation switches 4a to 4h of the navigation devices 2A and 2B are operated by the system control device 9, the display images of the display devices 3 of the navigation devices 2A and 2B are displayed. And the obtained display images are compared to inspect the transition of each display screen and the display contents.

  According to such a present Example, if the transition pattern of the display image of navigation apparatus 2A, 2B corresponds, and the display content also corresponds, the display transition and display content of both navigation apparatus 2A, 2B are normal. If there is a mismatch, it can be determined that one of the electrical devices is abnormal.

  As described above, according to the present embodiment, the display screen transition and the display content can be inspected with the coincidence / non-coincidence of the display screens of the navigation devices 2A and 2B. Therefore, it is possible to eliminate the hassle of creating a reference screen, no storage means for storing the reference screen in advance is required, and any screen at any operation stage can be arbitrarily inspected.

  Furthermore, since it is not necessary to create a reference screen, the preparation for the inspection only needs to be performed by the system control device 9 for screen transition procedure work. In this case, there is no need to associate the reference screen capture with the determination, and this procedural work does not need to use the entire display inspection system, and the procedural work is performed by easily operating only the system controller 9 in another place. obtain. In addition, even with a navigation device having a different specification to be inspected (a navigation device of another model), if a plurality of navigation devices having the specification are prepared, a display inspection can be easily performed.

  Further, according to the present embodiment, the switch operating device 19 is operated by pressing the pressing member 16 configured to include the fingers 18A and 18B having the same interval as the arrangement interval of the navigation devices 2A and 2B. Since the configuration includes the robot 6 (actuator) to be operated, the same kind of operation switches of the navigation devices 2A and 2B can be pushed and operated simultaneously without making a mistake. In this case, it is sufficient that the pushing operation can be performed almost simultaneously, even if not completely simultaneously.

Also, since two inspection results can be obtained by operating two navigation devices at the same time, the data for the two devices can be obtained when checking the reproducibility of defects that occur less frequently and checking the effectiveness of the countermeasure software. Obtainable.
In this case, according to the present embodiment, since the actuator is composed of the robot 6, the plurality of operation switches 4a to 4h can be favorably pushed in a predetermined order, and even if the operation order is changed, Respond quickly to changes.

  In addition, since the navigation device is the target electrical device as the electrical device to be inspected, the navigation device is in a situation where the number of display screen transitions is large and the display inspection is considerably troublesome. It can be done easily and easily.

  Moreover, since it is set as the structure provided with multiple attachment holes 17a and 17b for selectively attaching the said fingers 18A and 18B to the said pushing member 16, while being able to change the attachment position of the fingers 18A and 18B, FIG. As shown in FIGS. 9 and 10, a plurality of fingers having different forms can be attached. 9 and 10 show a second embodiment of the present invention. In this case, for example, a plurality of fingers having different forms such as a finger 20 for horizontal pressing and a finger 21 for vertical pressing can be attached. In this case, as the navigation device, a navigation device 24 having an audio device (or map data reading device) 23 on the back side of the display device 22 is suitable as an inspection object. In this device, the display device 22 is movable by an operation switch 25a, and when the display device 22 slides downward and forward by turning on the operation switch 25a, a DVD-ROM or the like can be taken in and out of the display device 22 accommodating portion. . The eject switch of the DVD-ROM is an operation switch 25b.

  In this case, from the state shown in FIG. 9, the operation switch 25a is pushed by the horizontal pushing finger 20 to pull the display device 22 forward (see FIG. 10), and the operation switch 25b is pushed by the vertical pushing finger 21. The push operation can be performed, so that various push operation forms can be supported.

In addition, this invention is not limited to the said Example, You may implement as changed as follows.
The electric device to be inspected is not limited to the navigation device, and may be a mobile phone or the like. Further, the number of electrical devices to be inspected is not limited to two and may be more.
Further, instead of the image capturing device, a camera that captures display screens of a plurality of electrical devices may be used.
The operation switch may be a touch input switch formed on the display screen.
