The vibration data to be inspected is compared with master vibration data to detect the occurrence of abnormal vibrations.

The master acoustic data is data for determining an abnormality based on the acoustic data during an acoustic inspection in the inspection process. The master sound data is a time change in sound detected from a game machine of the same type as the game machines 3 and 5, which is operating normally according to the test sequence, its envelope, and a master spectrum. The acoustic data to be inspected is compared with master acoustic data to detect the occurrence of abnormal sounds.

The master temperature time variation data is data for determining an abnormality based on temperature data during a temperature inspection in the inspection process. The master temperature temporal change data is the temporal change in temperature detected from gaming machines of the same type as the gaming machines 3 and 5, which are operating normally according to the inspection sequence. The temperature data to be inspected is compared with a pattern of fluctuations (actually measured temperature fluctuations over time) shown by the temperature data, and abnormal heat generation is detected.

FIG. 5 is a diagram showing a display example of the test result information 17C.

The test result information 17C includes, for example, a test target item 17D, a determination result 17E, and a details button 17F. The inspection target items 17D include, for example, items indicating inspection contents, such as "video inspection," "vibration inspection," "acoustic inspection," and "temperature inspection." In the determination result 17E, "OK" indicating that the item is determined to be normal or "NG" indicating that the item is determined to be abnormal is displayed as the inspection result corresponding to each item of the inspection target items 17D. The details button 17F is a button for inputting an instruction to display details of the examination. The details button 17F enables input operations for test items for which the test result is determined to be abnormal ("NG"), for example. In response to an operation on the display device 17, the CPU 11 causes the display device 17 to display detailed information indicating the content determined to be abnormal. Detailed information includes the installation position of the sensor that was determined to be abnormal (sensor identification information), the name of the part to which the sensor is installed, and a video or still image taken by the camera 29 showing the situation that was determined to be abnormal. and so on. When displaying a moving image or a still image, the moving image or still image at the same timing as the master image may be displayed so that the two can be compared.

Next, the inspection operation by the inspection apparatus 1 in this embodiment will be explained.

FIG. 6 is a flowchart showing the test preparation procedure before starting the testing process by the testing device 1, and FIG. 7 is a flowchart showing the testing process by the testing device 1 in this embodiment.

First, in preparation for inspection, the vibration sensor 23, temperature sensor 25, and microphone 27 are attached to each of the gaming machines 3 and 5 to be inspected (step S01). Further, the vibration sensor 23, the temperature sensor 25, and the microphone 27 are connected to the inspection device 1 via, for example, pickup terminals 23P, 25P, and 27P. It is assumed that the mounting position of the sensor (sensor identification information) or the name of the part to which the sensor is mounted is input by operating the input device 19, for example, and stored in the storage device 15 in advance. This information is referenced when an abnormality in operation is detected and the sensor that outputs the inspection data in which the abnormality in operation is detected or the component to which the sensor is attached is identified.

Next, the gaming machines 3 and 5 each equipped with each sensor are set on an inspection table as shown in FIG. 3 (step S02). In front of the examination table, a camera 29 is arranged so that the photographing range includes the gaming machines 3 and 5 set on the examination table.

Next, the sequence device 21 of the inspection device 1 is connected to each control unit (not shown) of the gaming machines 3 and 5 (step S03). That is, the control signal cable is connected between the interface (I/F) 22 of the inspection device 1 and the control units of the gaming machines 3 and 5. The control units of the gaming machines 3 and 5 can operate each part according to a control signal input through the control signal cable.

Next, inspection processing by the inspection device 1 will be explained.

After the inspection preparations have been made as described above, the inspection apparatus 1 starts inspection processing based on the inspection program code in response to input of an instruction to execute inspection processing.

The CPU 11 causes the gaming machines 3 and 5 to start a preset series of operations through the sequence device 21 based on the test sequence data. Further, while the gaming machines 3 and 5 are being operated according to the inspection sequence, the CPU 11 causes the storage device 15 to store video data of a moving image shot by the camera 29, and also causes the vibration sensors attached to the gaming machines 3 and 5 to be stored in the storage device 15. 23. The test data (vibration data, temperature data, acoustic data) input from the temperature sensor 25 and microphone 27 is stored in the storage device 15 (step S04).

The CPU 11 executes a video test, a vibration test, an acoustic test, and a temperature test in parallel on the test data stored in the storage device 15 (steps S05 to S08).

Here, an example of a video test in this embodiment will be described.

FIG. 8 is a diagram schematically showing an inspection sequence preset for the gaming machines 3 and 5. As shown in FIG. As shown in FIG. 8, in the inspection sequence, the operation state at the timing when time t1, t2,..., tm,...,t end has elapsed with reference to the operation (start operation) at the inspection start timing (t start). Defined. (t end) indicates the timing at which the test ends. That is, by executing the operation to be inspected at times t1, t2, ..., tm, ..., it is determined whether the still images extracted at times t1, t2, ..., tm, ... are in a normal operating state. judge.

As the operating state at each timing, for example, lighting/blinking of the lamps C (3C1, 3C2, 3C3), operation of the electric accessory 3B, display contents on the display 3A, etc. are defined. In addition, if a component that is a heat generation source takes a relatively long time to rise in temperature, the inspection sequence shown in Figure 8 may be one that is operated continuously over multiple periods of time. shall be. Note that the times t1, t2, . . . , tm may be at regular intervals, or may be different times depending on the content of the inspection operation.

FIG. 9 is a diagram for explaining the flow of video inspection in this embodiment.

The CPU 11 samples images from the video data at intervals shorter than times t1, t2, . . . , tm, and generates a sampled still image 40. The CPU 11 searches for a sampled still image 40 based on master image data indicating a start image corresponding to the timing (t start) in order to detect the timing (t start) of starting the inspection of the moving image data. When a sampling still image corresponding to the start image is retrieved, the CPU 11 sets the retrieved sampling still image as the start timing (t start) of the inspection sequence.

The CPU 11 extracts inspection target still images 41 corresponding to times t1, t2, . The still image 41 to be inspected includes a start image I (t start), an image I (t1), an image I (t2), ..., an image I (tm), ..., an end image I (t end).

The CPU 11 sequentially sets images I(tn) 42 to be inspected from the still image 41 to be inspected, and creates master image data (master image ( tn)) to detect operational abnormalities.

As shown in FIG. 9, the image I(tn) 42 to be inspected includes images corresponding to the two gaming machines 3 and 5. Therefore, the CPU 11 selects an image corresponding to the gaming machine 3 (hereinafter referred to as the left image IL(tn)) and an image corresponding to the gaming machine 5 (hereinafter referred to as the right image IR(tn)) from the image I(tn) 42. Execute separation processing to separate.

Next, the CPU 11 performs malfunction determinations 43 and 44 on the left image IL (tn) and the right image IR (tn), respectively.

In malfunction determination 43, the CPU 11 executes a difference process to extract a difference image representing the difference between the left image IL (tn) and the master image (tn) corresponding to the time (tn).

That is, the CPU 11 counts the number of remaining pixels NRP(tn) having a pixel value equal to or greater than a preset threshold for pixel value determination, for the left side difference image at time (tn) generated by the difference processing. Then, the CPU 11 executes a comparison process to compare the number of remaining pixels NRP (tn) with a preset threshold for determining malfunction. As a result, if the number of remaining pixels NRP (tn) is equal to or greater than the threshold, the CPU 11 determines that an abnormality has occurred in the operation at the timing (tn), and the number of remaining pixels NRP (tn) is less than the threshold. If so, it is determined that the operation at timing (tn) is normal.

When it is determined that there is an operational abnormality in the video test, the CPU 11 stores data for displaying the details of the examination in the storage device 15 together with data indicating the operational abnormality as a determination result (step S09). The data for displaying the details of the examination includes, for example, the timing (tn) when the abnormal operation occurred, the left image IL (tn) at the timing (tn), and a preset time period (for example, 10 minutes) including the timing (tn). Contains video data including seconds). That is, in the test result information 17C shown in FIG. 4, when detailed display of the test is instructed by operating the details button 17F, a still image determined to be an abnormal movement (left image IL(tn)) or a still image of the abnormal movement is displayed. Enable to display videos including before and after the occurrence.

Similarly, in the malfunction determination 44, the CPU 11 executes the same process as the above-mentioned left image IL (tn) based on the right image IR (tn) and the master image (tn) corresponding to the time (tn). do. A detailed explanation will be omitted.

In this way, in the video inspection, it is possible to detect an operational abnormality that can be determined from the appearance based on the video taken by the camera 29. The inspection device 1 inspects the plurality of gaming machines 3 and 5 whose videos have been taken within a single angle of view by the camera 29, based on the corresponding left image IL (tn) and right image IR (tn), respectively. Malfunction determinations 43 and 44 can be performed individually. Therefore, the test preparation work can be performed on the plurality of gaming machines 3 and 5 all at once, and then the test process can be started, so that the work load can be reduced and the test time can be shortened.

Next, an example of a vibration test in this embodiment will be described.

FIG. 10(A) is a diagram showing the concept of master vibration data stored in advance in the storage device 15 for vibration testing. The master vibration data is data indicating vibrations that occur when the gaming machines 3 and 5 are operating normally. FIG. 10(A) shows a master vibration time change representing the amplitude change of vibration detected from the gaming machines 3 and 5 when operating normally according to the inspection sequence, and a master vibration envelope corresponding to the master vibration time change. There is. FIG. 10(B) is a diagram showing a master vibration spectrum generated based on the master vibration envelope.

FIG. 11(A) shows the measured vibration time change representing the vibration amplitude change indicated by the vibration data input from the vibration sensor 23 while the game machines 3 and 5 are controlled according to the inspection sequence, and the measured vibration time change. The corresponding measured vibration envelope is shown. FIG. 11(B) is a diagram showing a measured vibration spectrum generated based on a measured vibration envelope.

The CPU 11 compares the master vibration spectrum and the actually measured spectrum, and determines that an abnormal operation has occurred when the difference is greater than or equal to a preset threshold. That is, by using the master vibration spectrum and the actually measured vibration spectrum, it is possible to detect an abnormality based on the overall change while being controlled by the inspection sequence to be inspected.

When it is determined that there is an operational abnormality in the vibration test, the CPU 11 causes the storage device 15 to store data for displaying the details of the examination together with data indicating the operational abnormality as a determination result (step S10). The data for displaying the details of the inspection includes, for example, the mounting position (sensor identification information) of the vibration sensor 23 that outputs the vibration data determined to be abnormal in operation, or the name of the part to which the sensor is mounted. Also good.

Furthermore, the CPU 11 may not only detect an abnormality based on the overall change during the inspection target, but also perform vibration calculation that can identify the timing of abnormal operation. That is, the CPU 11 compares the master vibration envelope and the actual measurement envelope at each preset time, for example, and if the difference is greater than or equal to a preset threshold, the CPU 11 determines that an abnormal operation has occurred at the time to be compared. It is determined that the When determining that an abnormal operation has occurred, the CPU 11 causes the storage device 15 to store data indicating the time at which the abnormality occurred as data for displaying details of the inspection. Further, the CPU 11 stores vibration data for a preset time (for example, 10 seconds) including the time when it is determined that an abnormality has occurred.

In addition, in the above explanation, a vibration test for vibration data input from one vibration sensor 23 is explained, but when a plurality of vibration sensors 23 are installed in each of the gaming machines 3 and 5, performs similar processing on the vibration data input from each vibration sensor 23.

Further, the CPU 11 may determine the presence or absence of abnormal operation based on a combination of determination results of vibration data input from the plurality of vibration sensors 23. For example, the determination result for vibration data input from one vibration sensor 23 alone does not determine abnormal operation, but the determination result for vibration data input from adjacent vibration sensors 23 simultaneously determines abnormal operation. If so, it is determined that an abnormal operation has occurred.

In this way, in the vibration test, it is possible to detect abnormal operation based on the vibration data input by the vibration sensor 23.

Next, acoustic testing in this embodiment will be explained.

The acoustic test is performed in the same manner as the vibration test described above, and a detailed description thereof will be omitted. In the acoustic test, the CPU 11 uses master acoustic data (master acoustic envelope, master acoustic spectrum) indicating the acoustic changes that occur when the gaming machines 3, 5 are operating normally, and the gaming machines 3, 5 according to the inspection sequence. Abnormal operation is detected by comparison with acoustic data (actually measured acoustic envelope, measured acoustic spectrum) input from the microphone 27 while being controlled.

If it is determined that there is an operational abnormality in the acoustic test, the CPU 11 causes the storage device 15 to store data for displaying the details of the examination together with data indicating the operational abnormality as a determination result (step S11).

Next, a temperature test in this embodiment will be explained.

FIG. 12 shows master temperature time fluctuation data stored in advance in the storage device 15 for temperature inspection, and actual temperature time fluctuation data inputted from the temperature sensor 25 while the gaming machines 3 and 5 are being controlled according to the test sequence. FIG. 2 is a diagram showing the concept of data.

The CPU 11 compares the master temperature temporal fluctuation data and the measured temperature temporal fluctuation data, for example, at each preset time, and if the difference is greater than or equal to a preset threshold, the CPU 11 determines that there is an abnormality at the time to be compared. It is determined that an action is occurring. When the CPU 11 determines that an abnormal operation has occurred, the CPU 11 causes the storage device 15 to store data indicating the time when the abnormality occurred as data for displaying details of the examination (step S12). Furthermore, the CPU 11 stores temperature data for a preset time (for example, 10 seconds) including the time when it is determined that an abnormality has occurred.

In this way, when the CPU 11 finishes the video test, vibration test, acoustic test, and temperature test for the test data stored in the storage device 15 (Step S13, Yes), the CPU 11 displays the test results on the display device 17 (Step S10). .

The CPU 11 displays a test result screen, as shown in FIG. 4, for example. For example, the CPU 11 determines that the gaming machines 3 and 5 to be inspected pass the inspection if no abnormal operation is detected in any of the video inspection, vibration inspection, acoustic inspection, and temperature inspection.

In addition, when an abnormal operation is detected in any of the video test, vibration test, acoustic test, and temperature test, the CPU 11 displays "" in the test result information 17C (17C1, 17C2) indicating that it has been determined that there is an abnormality. NG” is displayed. Further, when the detailed button 17F corresponding to an inspection item determined to have an abnormality ("NG") as an inspection result is operated, the CPU 11 stores the information in the storage device 15 at the time of each inspection (steps S09 to S12). Display details based on the data.

Thereby, it is possible to easily confirm not only which operation test detected an abnormality, but also what kind of operation abnormality it is (the location where the abnormality occurs, the situation when the abnormality occurs, etc.).

Note that in the above explanation, operational abnormalities are detected individually for each video test, vibration test, acoustic test, and temperature test, but abnormalities can be detected based on the test results of any combination of multiple tests. You may also do this. In this case, it is assumed that the storage device 15 stores in advance data for determining abnormal operation based on a combination of a plurality of tests.

FIG. 13 is a diagram showing a correspondence relationship between times when an abnormality in operation is detected by a video test, a vibration test, an acoustic test, and a temperature test. For example, in FIG. 13, an operational abnormality E11 detected by an operational test, an operational abnormality E21 detected by a vibration test, and an operational abnormality E31 detected by an acoustic test occur at the same timing. Further, while the operational abnormality E41 is detected by the temperature test, the operational abnormality E22 occurs by the vibration test. Furthermore, the operational abnormality E23 detected by the vibration test and the operational abnormality E32 detected by the acoustic test occur at the same timing.

In this way, when an abnormality is detected in multiple operational tests at the same time, the CPU 11 determines the timing of the test sequence in which the operational abnormality was detected (which part is being driven), and the timing of the abnormal operation. Based on the detected combination of inspection processes, etc., the location of the abnormality is estimated by referring to the data for determining abnormal operation based on the combination of a plurality of inspections stored in the storage device 15, and the inspection result screen is displayed. to be displayed.

Thereby, it is possible to easily confirm in more detail what kind of operational abnormality is occurring (the location where the abnormality occurs, the situation when the abnormality occurs, etc.).

Note that in the above description, the video test, vibration test, acoustic test, and temperature test are performed in parallel, but each test may be performed in any order. In this case, by storing the test results of each test in association with the timing of the test sequence, the test results of each test can be associated as shown in FIG. 13.

The inspection device 1 in this embodiment performs highly accurate operation inspection and design quality by performing operation abnormality detection using moving images as well as operation abnormality detection using vibration, sound, and heat. It can lead to improvement.

The inspection apparatus 1 according to an embodiment of the present invention has been described above based on a specific example.
