DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fault diagnosis system according to the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to the embodiment.

[0013] 1 is a perspective view showing a fault diagnosis system 10 according to an embodiment of the present invention and a lift-up gate (outdoor structure) 12. The fault diagnosis system 10 is applied to the lift-up gate 12.

[0014] The lift-up gate 12 is installed on the front side of the garage, for example, to separate the garage on the house side from the front road, etc. Figure 1 shows the lift-up gate 12 in a closed state. In the closed state, the door body 20 is lowered vertically. Although not shown, in the open state, the door body 20 is raised horizontally.

[0015] The lift-up gate 12 comprises two upright pillars 14a, 14b, a rotation support mechanism 16 provided on each of the pillars 14a, 14b, arms (movable parts) 18 connected to the rotation support mechanisms 16, and a door body 20 attached to the tip of the arm 18. The pillars 14a, 14b are fixed to a foundation 22. Each arm 18 is made up of a main arm 18a and a sub-arm 18b. The tips of the pair of left and right arms 18 are connected and reinforced by a connecting rod 19.

[0016] Fig. 2 is a partially enlarged perspective view of the support post 14a of the lift-up gate 12. In Fig. 2, some covers have been removed so that the internal mechanism can be seen. The lift-up gate 12 can be opened and closed automatically, and the support post 14a is provided with a control unit 24, a motor 26, and an angle sensor (angle detection means) 28 for automatic opening and closing. For simplicity, a limit switch (angle detection means) may be used instead of the angle sensor 28.

[0017] The motor 26 rotates the arm 18 via the rotary support mechanism 16. The angle sensor 28 detects the rotation angle of the arm 18. The control unit 24 reads the detected angle (detection result) of the angle sensor 28 and controls the motor 26. The control unit 24 has a functional section for fault diagnosis, etc., which will be described later. The lift-up gate 12 is of a remote control type, and a receiving section 32 that receives a signal from a remote control operation section 30 (see FIG. 1) is provided on the support post 14a. The control unit 24 can control the motor 26 based on the operation of the remote control operation section 30 via the receiving section 32. The receiving section 32 is provided near the top of the support post 14a. The motor 26 and the angle sensor 28 are provided near the rotary support mechanism 16. The control unit 24 is provided slightly below the motor 26.

[0018] FIG. 3 is a perspective view of the control unit 24 as seen from the front side. In FIG. 3, a cover covering the front side of the control unit 24 has been removed. The control unit 24 is provided with a power switch 34, a power lamp 36, two limit lamps 37, a mode changeover switch 38, an up switch 40, a down switch 42, a stop switch 44, and a connector 46. The limit lamp 37 is a lamp that lights up when the arm 18 moves to the upper limit and when it moves to the lower limit. The mode changeover switch 38 is a switch for switching between manual mode and automatic mode. The up switch 40 and the down switch 42 are switches for driving the motor 26 to raise / lower the arm 18. The stop switch 44 is a switch for stopping the up and down movement of the arm 18. A roof 46a is provided on the connector 46.

[0019] Next, the fault diagnosis system 10 will be described. Fig. 4 is a block diagram of the fault diagnosis system 10. Some of the components of the fault diagnosis system 10 are included in the lift-up gate 12. In this embodiment, the target to be diagnosed by the fault diagnosis system 10 is the lift-up gate 12, but the system can also be applied to other outdoor structures equipped with moving parts, such as shutters and electric lock gates. Furthermore, fault diagnosis in this application is defined in a broad sense and may also include a function of fault estimation.

[0020] The fault diagnosis system 10 includes the electrical components of the lift gate 12, namely, the control unit 24, the motor 26, the angle sensor 28, the receiving unit 32, and the switches 48. The switches 48 representatively show the above-mentioned power switch 34, the mode change switch 38, the up switch 40, the down switch 42, and the stop switch 44. The remote control operation unit 30 is also included in the fault diagnosis system 10. The fault diagnosis system 10 further includes a tablet terminal 50.

[0021] The control unit 24 has a control unit 24a, a fault diagnosis unit 24b, a construction state confirmation unit 24c, a report creation unit 24d, a monitoring unit 24e, an abnormality determination unit 24f, a communication unit 24g, and a storage unit 51. Of these functional units, the storage unit 51 is configured with hardware, and the other functional units may be realized, for example, by causing a processor such as a CPU (Central Processing Unit) to execute a program, that is, by software, or may be realized by hardware such as an IC (Integrated Circuit), or may be realized by a combination of software and hardware.

[0022] The fault diagnosis method according to the embodiment of the present invention is a method in which the processor of the control unit 24 executes the control unit 24a, the fault diagnosis unit 24b, the construction state confirmation unit 24c, the report creation unit 24d, the monitoring unit 24e, the abnormality determination unit 24f, and the communication unit 24g. Also, the fault diagnosis program according to the embodiment of the present invention causes the processor of the control unit 24 to execute the functions of the control unit 24a, the fault diagnosis unit 24b, the construction state confirmation unit 24c, the report creation unit 24d, the monitoring unit 24e, the abnormality determination unit 24f, and the communication unit 24g.

[0023] The control unit 24a controls the drive of the motor 26 while referring to the angle detected by the angle sensor 28 based on the operation of the remote control operation unit 30 or the switches 48. The fault diagnosis unit 24b is a functional unit that performs fault diagnosis and the like in cooperation with the tablet terminal 50. The construction state confirmation unit 24c is a functional unit that mainly confirms the construction state of the lift-up gate 12. The construction state confirmation unit 24c compares the input construction state with a predetermined reference state. The monitoring unit 24e is a functional unit that monitors the detected angle of the angle sensor 28 and stores the operation history in the memory unit 51. The abnormality determination unit 24f is a functional unit that determines the presence or absence of an abnormality based on the monitoring result by the monitoring unit 24e and stores the detected abnormality in the memory unit 51. The communication unit 24g is a functional unit that communicates with the tablet terminal 50. The memory unit 51 is a part that stores data and programs.

[0024] The tablet terminal 50 has a touch panel display 52, and input and output are possible through the display 52. ​​Input is possible through the display 52, for example, by tapping or dragging on the screen, or by using a software keyboard. An external physical keyboard or mouse may also be used for input from the tablet terminal 50.

[0025] The tablet terminal 50 can communicate with the control unit 24 by connecting the connector 54 via the harness 54a to the connector 46. The tablet terminal 50 has an input / output unit 50a that cooperates with the control unit 24 to input and output data to and from the display 52, and a communication unit 50b that communicates with the control unit 24. The input / output unit 52a and the communication unit 52b are functional units configured by software, hardware, or a combination of these. The tablet terminal 50 can store data in a memory card 56. The memory card 56 is detachable from a specified port. The tablet terminal 50 is of a size suitable for carrying by an operator. The tablet terminal 50 may be replaced by a notebook computer or a smartphone. The communication between the tablet terminal 50 and the control unit 24 may be wireless.

[0026] Next, the operation of the fault diagnosis system 10 will be described. The fault diagnosis system 10 operates both during normal operation and during maintenance. Maintenance includes periodic maintenance and repair of faults that occur during operation.

[0027] Normally, the tablet terminal 50 is not connected to the control unit 24. Normally, the control unit 24a controls the drive of the motor 26 while referring to the angle detected by the angle sensor 28, as described above, based on the operation of the remote control operation unit 30. In addition, the monitoring unit 24e and the abnormality determination unit 24f monitor the angle detected by the angle sensor 28, perform abnormality determination, and store the operation history and the number of abnormalities in the storage unit 51.

[0028] On the other hand, in the fault diagnosis system 10, during maintenance, the connector 46 and the connector 54 are connected, and the control unit 24 and the tablet terminal 50 are connected and are in a state in which they can communicate with each other. When the control unit 24 and the tablet terminal 50 are connected, they recognize that they are connected to each other automatically or by a predetermined operation and start communication. During maintenance, the tablet terminal 50 mainly acts as an input / output terminal of the control unit 24. During maintenance, the fault diagnosis unit 24b, the construction state confirmation unit 24c, and the report creation unit 24d act independently or cooperatively. In summary, during maintenance, history confirmation, construction state confirmation, fault diagnosis, and report creation are performed in this order. In addition, data stored in the memory unit 51 by the monitoring unit 24e and the abnormality determination unit 24f are appropriately referred to.

[0029] 5 is an initial screen that appears on the display 52 during maintenance such as abnormality diagnosis. In the following description of the display screens of the display 52, basically, buttons, areas, etc. on one screen are denoted with the same numbers and distinguished by alphabetical subscripts, but even in other screens, those with the same functions are denoted with the same reference numerals and detailed descriptions thereof are omitted.

[0030] On the initial screen of FIG. 5, buttons 60a and 60b are displayed. Button 60a is a status check button, and when tapped, the screen changes to that of FIG. 6(a). Button 60b is a specification / installation status defect diagnosis button, and when tapped, the screen changes to that of FIG. 7. On this initial screen, time 60c and time setting button 60d are displayed. By tapping the time setting button 60d and performing a predetermined operation, it is possible to adjust the time in the control unit 24 and correct the display of time 60c.

[0031] 6 shows the history / abnormality confirmation screen, where (a) is the first screen and (b) is the second screen. On this screen, the operation history monitored by the monitoring unit 24e and stored in the memory unit 51, and the abnormality judged by the abnormality judgement unit 24f and stored in the memory unit 51 are displayed.

[0032] 6(a) area 62a displays the number of times of ascent, descent, and obstacle detection obtained by the monitoring unit 24e monitoring the angle detected by the angle sensor 28. Obstacle detection indicates that the angle detected by the angle sensor 28 did not change at an appropriate speed while the motor 26 was being driven to rotate, and is displayed separately for ascent and descent.

[0033] The abnormality count area 62b is an area that displays the abnormalities and their number of times that the abnormality determination unit 24f determines by associating the angle detected by the angle sensor 28 with the operating state of the motor 26, and specifically displays the number of times that the arm 18 or the door body 20 was forced up or down and that the motor control was abnormal. A forced up is when the angle detected by the angle sensor 28 indicates an increase when the motor 26 is not being rotated, and a forced down is the opposite. A motor control abnormality is recognized and counted when the control unit 24 detects that the motor 26 has continued to move for a predetermined time or more while the motor 26 is being rotated and forcibly stops the motor 26. This is because, if the motor is normal, the upper and lower limit positions can be authenticated within the predetermined time. Button 62c is a button for returning to the initial screen of Fig. 5. Button 62d is a button for moving to the screen of Fig. 7. Button 62e is a button for moving to the second screen of the history / abnormality confirmation screen of Fig. 6(b). The operation history and the number of abnormalities can be reset by tapping the corresponding reset button.

[0034] Area 64a in Fig. 6(b) shows the cumulative power-on time. Area 64b shows the cumulative motor operation time. Area 64c shows the number of times the angle detected by angle sensor 28 has exceeded a specified limit value, with upper and lower limits displayed separately. Button 64d is a button for switching to the screen in Fig. 6(a).

[0035] Fig. 7 is a confirmation screen for the control unit 24. Buttons 66a and 66b are the sections that show the product specifications for a two-unit specification. Depending on the specifications of the lift-up gate 12, the control unit 24 may be a one-unit specification, in which case buttons 66a and 66b display the product specifications for a one-unit specification. On this screen, the maintenance target and specifications are selected. Button 66c is a button that returns to the initial screen of Fig. 5. Button 66d is a button that moves to the next screen of Fig. 8.

[0036] Each screen in Fig. 8A to Fig. 8C is a screen for checking the construction state performed by the construction state checking unit 24c. The construction state check in Fig. 8A to Fig. 8C is basically performed every time maintenance is performed, but may be omitted when the maintenance interval is short and it is clear that there will be no change in the state. In each screen in Fig. 8A to Fig. 8C, the construction state of the inputted lift-up gate 12 is compared with a predetermined reference state, and the judgment result is displayed as "OK" or "NG" adjacent to the input section. In Fig. 8A to Fig. 8C, mainly the construction is checked, and abnormality diagnosis of electrical equipment is performed in each screen in Fig. 9.

[0037] Fig. 8A shows the construction status confirmation screen, (a) being the first screen and (b) being the second screen. Area 68a in Fig. 8A(a) is an area for inputting the dimensions and weight of door body 20. Area 68b is an area for inputting the product color of posts 14a, 14b. Area 68c is an area for inputting the lot number. Button 68d is a button for moving to the screen of Fig. 8A(b).

[0038] Area 70a in Figure 8A(b) is an area for checking and inputting whether there have been any modifications to the door body 20 or the support pillars 14a, 14b. Area 70b is an area for checking and inputting the attachment position of the arm 18. Area 70c is an area for checking and inputting the connection state between the connecting rod 19 and the left and right main arms 18a. Area 70d is an area for measuring and inputting the floating width of a specified support fitting. Area 70e is an area for checking and inputting the connection state of the bolts and nuts of the main arm 18a and sub-arm 18b. Button 70f is a button that moves to the screen of Figure 8B(a).

[0039] Fig. 8B shows a construction status confirmation screen, (a) being its third screen, and (b) being its fourth screen. In Fig. 8B(a) and (b), the construction status of the pillars 14a and 14b is input. Areas 72a and 72b in Fig. 8B(a) are used to input the distance between the pillars 14a and 14b for the upper and lower ends, respectively. Area 72a is used to measure and input the distance on the house side, and area 72b is used to measure and input the distance on the road side. Area 72c is used to input the difference in dimensions input in areas 72a and 72b. Button 72d is used to move to the screen in Fig. 8B(b).

[0040] Fig. 8B(b) is a screen for inputting the inclination of the pillars 14a, 14b. Area 74a is an area for inputting the difference in position between the ends of the pillars 14a, 14b in the width direction. Area 74b is an area for inputting the difference in position between the ends of the pillars 14a, 14b in the depth direction. Button 74c is a button for switching to the screen of Fig. 8C(a).

[0041] Fig. 8C shows the construction status confirmation screen, (a) being the fifth screen, and (b) being the sixth screen. Area 76a in Fig. 8C(a) is an area for measuring and inputting the height of the two supports 14a, 14b. Area 76b is an area for inputting the difference in height between the two supports 14a, 14b input in area 76a. The height of the supports 14a, 14b is measured using a water tube or laser. When using a water tube such as a hose, water is poured in and one side is used as a reference, and the water on the other side is displaced, allowing the height to be measured. On the left side of the screen in Fig. 8C(a), a guide for measuring the height of the supports 14a and 14b is shown. A button 76c is a button for switching to the screen in Fig. 8C(b).

[0042] Fig. 8C(b) is a screen for diagnosing the suitability of the construction state inputted in the first to fifth screens and displaying the results. That is, if the interval between the pillars 14a, 14b, the inclination of the pillars 14a, 14b in the frontage direction, the inclination of the pillars 14a, 14b in the depth direction, the height of the pillars 14a, 14b, the mounting position of the arm 18, the presence or absence of modifications to the door body 20 and the pillars 14a, 14b, the connection state of the bolts and nuts of the connecting rod 19 and the main arm 18a, and the connection state of the bolts and nuts of the main arm 18a and the sub-arm 18b are appropriate, "OK" is displayed, and if they are inappropriate, "NG" is displayed. Also, if the data has not been inputted, a message to that effect is displayed. The button 77a is a button for moving to the screen of Fig. 9A(a).

[0043] 9A to 9E are screens related to fault diagnosis. Fault diagnosis on each of these screens is mainly performed under the action of fault diagnosis unit 24b. The fault diagnosis in Figs. 9A to 9E is basically performed when a fault occurs. The fault diagnosis in Figs. 9A to 9E mainly involves diagnosis of electrical equipment.

[0044] In the fault diagnosis in the fault diagnosis unit 24b, generally, first, it is confirmed whether the arm 18 operates at a normal speed by operating the remote control operation unit 30, the up switch 40, and the down switch 42 according to the display screens of Figs. 9A-9B. This confirms the presence or absence of an abnormality, and distinguishes whether the cause of the abnormality is in the command system (i.e., the remote control operation unit 30 and the receiving unit 32) or the drive system (i.e., the angle sensor 28 and the motor 26). Then, on the screen of Fig. 9C, the detected angle of the angle sensor 28 according to the operation is input, and the presence or absence of an abnormality in the angle sensor 28 is judged. Furthermore, the resistance value of the motor 26 is input on the screen of Fig. 9D, and the presence or absence of an abnormality in the motor 26 is judged, and a fault diagnosis is performed based on the input contents.

[0045] Fig. 9A shows a fault diagnosis screen, (a) being its first screen, and (b) being its second screen. Fig. 9A(a) is a screen for checking whether the power lamp 36 (see Fig. 3) is on, and if it is on, tap the button 78a displaying "YES" to move to the screen of Fig. 9A(b). If the power lamp 36 is off, tap the button 78b displaying "NO" to move to the screen of Fig. 9A(b).

[0046] Fig. 9A(b) is a screen for confirming whether the limit lamp 37 (see Fig. 3) lights up properly in response to the movement of the arm 18. If it lights up properly, tap the button 80a displaying "YES" to move to the screen of Fig. 9B(a). If the limit lamp 37 does not light up in response to the movement of the arm 18, tap the button 80b displaying "NO" to move to the screen of Fig. 9B(a).

[0047] FIG. 9B shows a fault diagnosis screen, where (a) is the third screen, (b) is the fourth screen, and (c) is the fifth screen. The screen in FIG. 9B(a) is a screen for confirming the opening / closing and stopping operations performed by the remote control operation unit 30. If the operation is normal, tap the button 82a displaying "YES", omit the display of the screen in FIG. 9B(b), and move to the screen in FIG. 9B(c). This is because no particular abnormality is found in the remote control operation unit 30, the receiving unit 32, the motor 26, etc. On the other hand, if the operation does not occur, there is an abnormality in one of the locations and diagnosis is required, so tap the button 82b displaying "NO" and move to the screen in FIG. 9B(b).

[0048] The screen in Fig. 9B(b) is a screen for confirming the opening / closing operation and stopping operation by operating another remote control operation unit 30, and if the operation is normal, it is confirmed that there is an abnormality in the original remote control operation unit 30. In this case, tap button 84a displaying "YES" to move to the screen in Fig. 9B(c). On the other hand, if there is no operation, it is diagnosed that the cause is something other than the remote control operation unit 30. In this case, tap button 84b displaying "NO" to move to the screen in Fig. 9B(c).

[0049] The screen of FIG. 9B(c) is a screen for confirming the opening and closing operation in the manual mode. If the operation is normal, tap the button 86a displaying "YES". In this case, the motor 26 and the angle sensor 28 are diagnosed as normal. On the other hand, if the operation is not normal, tap the button 86b displaying "NO". In this case, it is considered that there is an abnormality in the motor 26 or the angle sensor 28. In this case, the screen moves to the screen of FIG. 9C regardless of whether the button 86a or 86b is tapped. Note that even if the screen of FIG. 9B(a) is omitted and the screen of FIG. 9B(c) is displayed, the screen moves to the screen of FIG. 9B(b) by tapping the button 62c. This allows another remote control operation unit 30 to be operated on a trial basis.

[0050] In this way, in the fault diagnosis by the fault diagnosis unit 24b, the display 52 is displayed multiple times to input the status of the electrical equipment related to the lift-up gate 12, and fault diagnosis is performed based on the input content of the input display. In addition, when the "YES" button 82a is tapped on the input display screen of FIG. 9B(a) and when the "NO" button 82b is tapped, the case is distinguished and different displays are performed thereafter. In other words, the worker makes a selection input regarding the status of the lift-up gate 12, and the fault diagnosis unit 24b selectively displays in sequence on the display 52 the screens of FIG. 9B(a), (b), and (c) that guide the worker to identify the fault location, so that the worker does not need to determine the method himself to find the fault location, and can easily perform maintenance such as fault diagnosis. Furthermore, while necessary diagnostic work is performed, unnecessary diagnostic work is eliminated, making it possible to perform efficient and accurate diagnosis. In addition, in the screen of FIG. 9B, input is basically performed by selecting "YES" and "NO", making operation easy.

[0051] Fig. 9C is a sixth screen of the fault diagnosis screen, specifically, a screen for checking the angle sensor 28. In the case of the lift-up gate 12, an angle sensor 28 may be provided for each of the two posts 14a, 14b. In the screen of Fig. 9C, when there are two such angle sensors 28, two systems are displayed independently. When there is one angle sensor 28, only one system is displayed.

[0052] Area 88a in FIG. 9C is an area for displaying the angle detected by angle sensor 28 in real time. Area 88b is an area for inputting the value of angle sensor 28 when door body 20 is fully open. Area 88c is an area for inputting the value of angle sensor 28 when door body 20 is at about 45 degrees. Area 88d is an area for inputting the value of angle sensor 28 when door body 20 is fully closed. In this case, door body 20 is opened and closed in manual mode. Also, when fully open or fully closed, it is fixed with a specified lock pin. These steps are shown on the screen in FIG. 9C.

[0053] Area 88e is an area that automatically displays the angle detected by angle sensor 28 relative to the fully closed state. Area 88f is an area that judges whether the numerical value calculated in area 88e is appropriate and displays the judgment result. Button 88g is a button for switching to the screen in Fig. 9D. If there is an abnormality in the operation of the lift-up gate 12 and the angle detected by angle sensor 28 does not satisfy the judgment criterion, it can be determined that the cause of the abnormality is angle sensor 28.

[0054] Fig. 9D is the seventh screen of the fault diagnosis screen, specifically, a screen for checking the motor 26. In the case of the lift-up gate 12, a motor 26 may be provided for each of the two posts 14a, 14b. In the screen of Fig. 9D, when there are two such motors 26, two systems are displayed independently. When there is only one motor 26, only one system is displayed.

[0055] Area 90a in FIG. 9D is an area for measuring and inputting the resistance value between specified terminals of motor 26. This measurement is performed by connecting a test harness to the motor connector and using a tester. The upper right corner of the screen in FIG. 9D shows instructions for this type of measurement. Area 90b is an area for displaying suitability and measures based on the measured resistance value. Button 90c is a button for moving to the screen in FIG. 9E. If there is an abnormality in the operation of the lift gate 12 and the resistance value between the terminals of motor 26 does not meet the judgment criteria, it can be determined that the cause of the abnormality is motor 26.

[0056] Fig. 9E is an eighth screen of the fault diagnosis screen, specifically, a screen showing the final diagnosis result. An area 92a in Fig. 9E displays the diagnosis results obtained in the first to seventh screens. A button 92b is a button for storing such diagnosis results in the memory card 56. A button 92c is a button for returning to the initial screen of Fig. 5.

[0057] The operation history (including the number of abnormalities, etc.) detected by the monitoring unit 24e and the abnormality judgment unit 24f, and the failure diagnosed by the failure diagnosis unit 24b are output as data in a predetermined format by the report creation unit 24d. The predetermined format is a report format, and includes the data shown in FIG. 8C(b) and FIG. 9E, as well as the work date and time, the worker, the date of failure occurrence, the failure phenomenon, the model number, and the like. The predetermined format is set, for example, by a button 94a in FIG. 10, which will be described next. This data may be created separately for a stage before the failure diagnosis is performed and a stage after the failure diagnosis and the specified repair are performed. The output destination of this data is possible to store and output to the memory card 56 based on the screen operation in FIG. 9E, as well as to store and output to the memory unit 51 of the control unit 24, to display and output to the display 52, to print and output to a printer, and to transmit and output via a network.

[0058] 10 shows a screen for report processing. This screen can be displayed and operated even when the tablet terminal 50 is not connected to the control unit 24. In other words, the report creation unit 24d may be provided inside the tablet terminal 50.

[0059] Button 94a in FIG. 10 is a button for setting a report template, and by tapping it, a report in a format based on the selected template can be created. Button 94b is a button for selecting data, and by tapping it, the data to be operated on can be selected from the multiple accumulated data. Button 94c is a button for setting the save destination, and by tapping it, data can be stored in any storage unit other than memory card 56. Button 94d is a button for issuing an instruction to create a report based on the selected data. Box 94e is a section for checking the operation log.

[0060] In this way, reports of operation history and fault diagnosis are automatically created, so there is no need for handwritten notes, terminal input, clean copies, data conversion, etc., and there are no mistakes or omissions during creation, reducing the burden on workers. Reports can basically be created in a standardized prescribed format and submitted to a prescribed management department, making them easy to manage in that department.
