[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Figures 1 and 2 show an electric shutter device 1. The electric shutter device 1 is one embodiment of an electric opening / closing body device. In Figures 1 and 2, the electric shutter device 1 includes an electric shutter 2 that can open and close and shield an opening 12 for a window, a store or garage entrance, etc., formed in a wall 11 of a building 10, a control device 3 that controls the electric shutter 2, and an operation status information acquisition unit 4 that acquires operation status information of each part of the electric shutter device 1.

[0009] The electric shutter 2 comprises a winding-type shutter section 21 as an opening and closing body formed by connecting multiple slats, a winding section 22 capable of winding up and unwinding the shutter section 21, and a drive section 23 having a motor (not shown) that drives the winding section 22 to rotate.

[0010] The shutter unit 21 is wound up or down by the winding unit 22, which rotates by the drive unit 23, and the lower end moves upward or downward to open or close the opening 12. When moving from a closed state to an open state in the opening and closing operation of the electric shutter 2, the drive unit 23 drives the motor in the opening direction, causing the shutter unit 21 to be wound up by the winding unit 22. As a result, when the opening 12 is closed, the opening 12 opens from the bottom side. When moving from an open state to a closed state in the opening and closing operation of the electric shutter 2, the drive unit 23 drives the motor in the closing direction, causing the shutter unit 21 to be wound down by the winding unit 22. As a result, when the opening 12 is open, the opening 12 closes from the top side.

[0011] As shown in Fig. 2, the control device 3 includes functional units such as a control unit 31, a storage unit 32, and a communication unit 33. In Fig. 1, the control device 3 is shown separated from the electric shutter 2 so as to be disposed, for example, in a control box installed on an indoor wall, but the control device 3 may also be disposed, for example, in the housing of the electric shutter 2, near the rolled-up shutter unit 21.

[0012] The control unit 31 is configured with a CPU (Central Processing Unit) for controlling the electric shutter device 1, and controls the operation of each part of the electric shutter device 1. That is, the control unit 31 drives and controls the drive unit 23, thereby rotating the winding unit 22 and opening and closing the shutter unit 21. The control unit 31 controls the communication unit 33 to communicate with the external terminal 100. The external terminal 100 is associated with the electric shutter device 1, and is a terminal capable of wirelessly transmitting and receiving various information to and from the communication unit 33 of the control device 3, and is operated by a user or a maintenance person (hereinafter collectively referred to simply as "user"). The external terminal 100 is, for example, a remote control device, a mobile phone terminal, etc.

[0013] 3, the control unit 31 has a reception unit 311 and a switching unit 312. The reception unit 311 can receive various instruction requests to the electric shutter device 1 from a user operating the external terminal 100 via the communication unit 33. The control unit 31 has a normal operation mode 312a and an operation test mode 312b as control modes for the electric shutter device 1. The switching unit 312 can switch between operating the electric shutter device 1 in the normal operation mode 312a or the operation test mode 312b based on the instruction request from the user received by the reception unit 311.

[0014] The normal operation mode 312a is set as a default control mode in the switching unit 312. In the normal operation mode 312a, the control unit 31 controls the opening and closing operation of the shutter unit 21 of the electric shutter 2 in the vertical direction based on an operation instruction request from a user operating the external terminal 100. In this case, the operation instruction request includes operation instruction information for opening and closing the shutter unit 21. Specifically, the operation instruction request includes close instruction information for moving the shutter unit 21 in the closing direction, open instruction information for moving the shutter unit 21 in the opening direction, stop instruction information for stopping the opening and closing operation of the shutter unit 21 at any position, and the like.

[0015] The operation test mode 312b is a mode for diagnosing abnormalities by conducting an operation test of each part of the electric shutter device 1. The control unit 31 executes the operation test mode 312b by switching from the normal operation mode 312a to the operation test mode 312b using the switching unit 312, and performs abnormality diagnosis of the electric shutter device 1.

[0016] The switching unit 312 can switch from the normal operation mode 312a to the operation test mode 312b based on a predetermined timing preprogrammed in the storage unit 32 (described later) or based on a command request to execute the operation test mode 312b from a user operating the external terminal 100. Examples of the predetermined timing include timing at regular intervals after the electric shutter device 1 is installed and used, or timing after a certain number of opening and closing operations of the shutter unit 21. The period or number of opening and closing operations as the timing for automatically executing the operation test mode 312b can be changed by a setting operation performed by the user via the external terminal 100, for example. These timings can be detected by a timing device such as a timer (not shown) provided in the control device 3 or the like that measures the period from the start of use, or a counter (not shown) that counts the number of opening and closing operations of the shutter unit 21.

[0017] The storage unit 32 is configured with a storage device such as a solid state drive (SSD) or a random access memory (RAM). The storage unit 32 stores operation programs for executing various functions of the electric shutter device 1 in the normal operation mode 312a and the operation test mode 312b. The storage unit 32 also stores information on the test results of the operation test obtained by executing the operation test mode 312b. The storage unit 32 accumulates information on the test results for each execution of the operation test mode 312b as history information of the test results. The accumulated history information of the test results can be transmitted to the external terminal 100 via the communication unit 33 under the control of the control unit 31 when a read instruction request is received from a user via the external terminal 100, for example.

[0018] 2, the communication unit 33 has a receiving unit 331 and a transmitting unit 332. The receiving unit 331 is capable of receiving various instruction requests from the user transmitted from the external terminal 100. Information on the instruction request received by the receiving unit 331 is input to the control unit 31 and accepted by the accepting unit 311.

[0019] The transmission unit 332 can transmit various types of information related to the electric shutter device 1 to the external terminal 100. The information transmitted from the transmission unit 332 to the external terminal 100 includes information on the test results of the operation test executed in the operation test mode 312b.

[0020] When the operation test mode 312b is executed, the operation status information acquisition unit 4 acquires the operation status of each predetermined unit of the electric shutter device 1. Regarding the electric shutter device 1, the operation status may be, for example, the voltage value of the primary voltage, the voltage value of the step-down voltage, and the current value of the electric shutter device 1. Regarding the motor, the operation status may be, for example, a load measurement value that measures the torque of the motor, the rotation speed, rotation direction, and rotation position of the motor. Specific examples of the operation status information acquisition unit 4 for acquiring these operation statuses include a voltmeter, an ammeter, a load measurement meter, and a rotation position sensor. Regarding the communication unit 33, the operation status may be, for example, the communication status of the communication unit 33. The operation status of the communication unit 33 can be acquired, for example, by monitoring whether the transmission of predetermined operation test data by the transmission unit 332 has been successfully completed under the control of the control unit 31.

[0021] In the operation test mode 312b, two or more of these operation states are set as test items. In the operation test mode 312b, an operation test is performed individually for each of the multiple test items under the control of the control unit 31, and the operation state of each unit at that time is acquired by the operation state information acquisition unit 4. The acquisition results of the operation state information acquisition unit 4 are input to the control unit 31.

[0022] Next, the processing operation by the control unit 31 when performing an abnormality diagnosis on the electric shutter device 1 will be described with reference to Fig. 4 and Fig. 5. Fig. 4 and Fig. 5 explain the processing by the control unit 31 to execute the operation test mode 312b when a command to execute an operation test is received from the user via the external terminal 100.

[0023] First, in the electric shutter device 1, the control unit 31 sets the normal operation mode 312a as the default control mode by the switching unit 312, and stops the shutter unit 21. In this state, as shown in Fig. 4, in step S1, the control unit 31 monitors whether or not there is a command request to execute an operation test from the user via the external terminal 100.

[0024] If it is determined in step S1 that there is a request to instruct the user to perform an operational test (step S1: YES), the process proceeds to step S2. If it is determined that there is no request to instruct the user to perform an operational test (step S1: NO), the control unit 31 continues to monitor whether there is a request to instruct the user to perform an operational test.

[0025] When an instruction request to execute an operational test is received, in step S2, the control unit 31 switches the control mode to be executed from the normal operation mode 312a to the operational test mode 312b using the switching unit 312. As a result, the control unit 31 immediately executes a predetermined operational test in accordance with a predetermined operational test program.

[0026] A flowchart of the operation test is shown in FIG. 5. In step S21, the control unit 31 executes a communication check. Specifically, the control unit 31 transmits predetermined operation test data to the external terminal 100 via the transmission unit 332. The operation status information acquisition unit 4 monitors whether transmission by the transmission unit 332, which indicates the operation status of the communication unit 33, has been completed, i.e., whether the transmission has ended normally. When the external terminal 100 receives the operation test data, it may transmit a response signal to the electric shutter device 1. In this case, the control unit 31 can determine whether the transmission has ended normally by checking whether a response signal has been received from the external terminal 100, thereby determining whether the operation status of the communication unit 33 is normal. The test results of these communication checks are input to the control unit 31. After the communication check is completed, the process proceeds to step S22.

[0027] In step S22, the control unit 31 executes a voltage value check. Specifically, the control unit 31 detects and acquires the primary voltage, step-down voltage, and other internal operating conditions of the electric shutter device 1 supplied from the commercial power source using a voltmeter, which is the operating condition information acquisition unit 4. The control unit 31 compares the acquired voltage value with a preset threshold value for determining whether or not the voltage value is abnormal. If the comparison shows that the acquired voltage value is outside the predetermined threshold range, the control unit 31 determines that the voltage value is abnormal, and if the acquired voltage value is within the predetermined threshold range, the control unit 31 determines that the voltage value is normal. After the voltage value check is completed, the process proceeds to step S23.

[0028] In step S23, the control unit 31 detects the rotational position of the winding unit 22 using a rotational position sensor or the like, and acquires position information of the shutter unit 21 in the opening / closing direction. Based on the acquired position information of the shutter unit 21 in the opening / closing direction, the control unit 31 determines whether the shutter unit 21 is located in the opening direction or the closing direction relative to the intermediate position of the opening 12 in the vertical opening / closing direction. If the determination result shows that the shutter unit 21 is located in the opening direction relative to the intermediate position of the opening 12 in the opening / closing direction (step S23: YES), the process proceeds to step S24. If the shutter unit 21 is located in the closing direction relative to the intermediate position of the opening 12 in the opening / closing direction (step S23: NO), the process proceeds to step S25. If the shutter unit 21 is located in the intermediate position of the opening 12 in the opening / closing direction in step S23, the process may proceed to a predetermined one of step S24 and step S25.

[0029] In step S24, the control unit 31 controls the drive unit 23 to operate the stopped shutter unit 21 in the closing direction. In step S25, the control unit 31 controls the drive unit 23 to operate the stopped shutter unit 21 in the opening direction. The opening and closing operations of the shutter unit 21 in steps S24 and S25 move the shutter unit 21 in the closing or opening direction by a predetermined distance that is set in advance for the operation test. After opening and closing the shutter unit 21 by the predetermined distance, in step S26, the control unit 31 controls the drive unit 23 to stop the motor, and the process proceeds to step S27.

[0030] In step S27, the control unit 31 executes a current value check. Specifically, the control unit 31 uses the ammeter, which is the operating state information acquisition unit 4, to detect and acquire the current value, which represents the internal operating state of the electric shutter device 1, when the motor is driven to rotate in step S24 or step S25. In step S27, the control unit 31 compares the acquired current value with a preset threshold value for determining whether or not the current value is abnormal. If the comparison result shows that the acquired current value is outside the predetermined threshold range, the control unit 31 determines that the current value is abnormal, and if the acquired current value is within the predetermined threshold range, the control unit 31 determines that the current value is normal. After the current value check is completed, the process proceeds to step S28.

[0031] In step S28, control unit 31 executes a motor check. Specifically, control unit 31 detects and acquires information on the motor's operating state, such as the motor torque, motor rotation speed, rotation direction, and rotation position, when the motor is rotated in step S24 or step S25, using the load meter, rotation position sensor, and other components of operation state information acquisition unit 4. In step S28, control unit 31 performs an abnormality diagnosis on the acquired motor operating state. For example, in the case of abnormality diagnosis of motor torque, control unit 31 compares the acquired torque with a preset torque threshold. If the acquired torque is outside the predetermined threshold range, the control unit 31 determines that the motor is abnormal. If the acquired torque is within the predetermined threshold range, the control unit 31 determines that the motor is normal. Upon completion of the motor check, the operation test process in step S2 ends, and the process proceeds to step S3 in FIG. 6.

[0032] In step S3, the control unit 31 stores the test results of the communication check, voltage value check, current value check, and motor check together with detailed data information such as the date and time when the operation test was performed in the storage unit 32. Thereafter, the process proceeds to step S4.

[0033] In step S4, the control unit 31 controls the communication unit 33 to transmit the test results of the communication check, voltage value check, current value check, and motor check from the transmission unit 332 to the external terminal 100, and notifies the user of the test results.

[0034] Next, with reference to FIG. 6, a process in which the control unit 31 automatically executes the operation test mode 312b when the electric shutter 2 has performed a predetermined number of opening and closing operations will be described.

[0035] In step S101, the control unit 31 counts the number of times the shutter unit 21 of the electric shutter 2 has opened and closed using a counter (not shown). The control unit 31 compares the count value with a specified number of opening and closing operations to determine whether the opening and closing operations of the shutter unit 21 have reached the specified number of opening and closing operations. If it is determined in step S101 that the specified number of opening and closing operations has been reached (step S101: YES), the process proceeds to step S102. If it is determined in step S101 that the specified number of opening and closing operations has not been reached (step S101: NO), the control unit 31 continues counting the number of opening and closing operations of the shutter unit 21.

[0036] In step S102, the control unit 31 controls the communication unit 33 to send information from the transmission unit 332 to the external terminal 100 indicating that an operation test will begin because the shutter unit 21 has been opened and closed a predetermined number of times, and notifies the user of the start of the operation test. This allows the user to recognize that the electric shutter device 1 is in operation test mode. After the notification, the process proceeds to step S103.

[0037] In step S103, the control unit 31 switches the control mode to be executed from the normal operation mode 312a to the operation test mode 312b using the switching unit 312. As a result, the control unit 31 performs the predetermined operation test shown in Fig. 5 in accordance with the predetermined operation test program. The details of the operation test in step S103 are as described above, and therefore will not be described here. After the operation test is completed, the process proceeds to step S104.

[0038] In step S104, the control unit 31 stores the test results of the communication check, voltage value check, current value check, and motor check together with detailed data information such as the date and time when the operation test was performed in the storage unit 32. Thereafter, the process proceeds to step S105.

[0039] In step S105, the control unit 31 controls the communication unit 33 to transmit the test results of the communication check, voltage value check, current value check, and motor check from the transmission unit 332 to the external terminal 100, and notifies the user of the test results. After notifying the user of the test results, the control unit 31 resets the count value of the number of opening and closing operations of the shutter unit 21.

[0040] In this way, when the control unit 31 automatically executes the operation test mode 312b, the operation test may start at a timing not intended by the user. In this case, the user can recognize the execution information of the operation test mode 312b from the operation test start notification sent to the external terminal 100 in step S102 shown in Fig. 6. Therefore, a case where the user issues an operation instruction request for the electric shutter 2 from the external terminal 100 while the control unit 31 is executing the operation test mode 312b shown in Fig. 6, thereby performing a normal opening and closing operation of the shutter unit 21, will be described with reference to Fig. 7.

[0041] When the receiving unit 331 receives a user's operation instruction request for the electric shutter 2 from the external terminal 100, the control unit 201 determines in step S201 whether the operation test mode 312b is being executed. If it is determined in step S201 that the operation test mode 312b is not being executed (step S201: NO), the process proceeds to step S202. If it is determined in step S201 that the operation test mode 312b is being executed (step S201: YES), the process proceeds to step S203.

[0042] In step S202, the electric shutter device 1 is set to the normal operation mode 312a. Therefore, the control unit 31 controls the drive unit 23 based on the content of the operation instruction request from the user received by the receiving unit 331 to perform the operation. That is, if the operation instruction request is an instruction to open the shutter unit 21, the control unit 31 controls the drive unit 23 to operate the shutter unit 21 in the opening direction. If the operation instruction request is an instruction to close the shutter unit 21, the control unit 31 controls the drive unit 23 to operate the shutter unit 21 in the closing direction. After the operation based on the operation instruction request is completed, the processing ends.

[0043] In step S203, the electric shutter device 1 is set to the operation test mode 312b. Therefore, the control unit 31 performs an operation test interruption process. Specifically, the control unit 31 temporarily switches the control mode from the operation test mode 312b to the normal operation mode 312a in the switching unit 312. At this time, the operation state information of the electric shutter device 1, such as the voltage value and current value, which has been acquired in the operation test mode 312b, is temporarily stored in the memory unit 32, etc. After the operation test interruption process, the process proceeds to step S204.

[0044] In step S204, the control unit 31 controls the driving unit 23 based on the content of the operation instruction request from the user received by the receiving unit 331, in the same manner as in step S202, to perform the operation.

[0045] After starting the execution of the operation in step S204, the control unit 31 determines in step S205 whether the operation has ended. If it is determined in step S205 that the operation has ended (step S205: YES), the process proceeds to step 206. If it is determined in step S205 that the operation has not ended (step S205: NO), the process waits in step 205 until the operation has ended.

[0046] In step S206, the control unit 31 performs an operation test restart process. Specifically, the control unit 31 switches the control mode from the normal operation mode 312a to the operation test mode 312b again in the switching unit 312. Thereafter, the operation test of step S103 shown in Fig. 6 is restarted, and the remaining operation test interrupted in step S203 is carried out.

[0047] According to this embodiment, the following effects are achieved. The electric shutter device 1 of this embodiment is an electric shutter device 1 including a shutter unit 21 that is capable of opening and closing the opening 12, a drive unit 23 that drives the shutter unit 21, a communication unit 33 that communicates with the external terminal 100, and a control unit 31 that controls the drive unit 23 and the communication unit 33. The control unit 31 is configured to execute an operation test mode 312b as a control mode, and in the operation test mode 312b, an operation test is performed for each of a plurality of test items to diagnose an abnormality. This makes it possible to diagnose an abnormality at any timing to determine whether the functions of each part of the electric shutter device 1 are normal. When performing the operation test, there is no need to consider on-site influences such as vibrations caused by an overload on the motor, making it easy to determine an abnormality caused by the product.

[0048] In this embodiment, in operation test mode 312b, control unit 31 controls drive unit 23 to operate shutter unit 21 in the closing direction when shutter unit 21 is located in a position closer to the opening direction than the intermediate position of opening 12 in the opening / closing direction, and to operate shutter unit 21 in the opening direction when shutter unit 21 is located in a position closer to the closing direction than the intermediate position of opening 12 in the opening / closing direction. This makes it possible to prevent erroneous determination of an abnormality due to an overload on the motor when shutter unit 21 is opened in a fully open state or closed in a fully closed state.

[0049] In this embodiment, the control unit 31 controls the communication unit 33 to transmit the test results of the operation test mode 312b to the external terminal 100. This allows the user to check the test results of the operation test.

[0050] In this embodiment, a memory unit 32 is provided that accumulates the test results of the operation test mode 312b. This allows the user to use the accumulated test results to predict failures in the electric shutter device 1, for example, by comparing the current test results with past test results.

[0051] In this embodiment, the control unit 31 has a reception unit 311 that receives an execution instruction request for the operation test mode 312b from the external terminal 100. This allows the user to perform an abnormality diagnosis of the electric shutter device 1 at any timing desired by the user.

[0052] In this embodiment, the control unit 31 executes the operation test mode 312b at predetermined intervals or after a predetermined number of opening and closing operations of the shutter unit 21. This allows the operation test to be performed automatically and periodically to diagnose abnormalities, eliminating the need for user operation.

[0053] In this embodiment, the period and the number of opening and closing operations can be changed by the user, which allows the operation test to be carried out according to the user's preference and in accordance with the usage status of the electric shutter device 1, thereby further improving convenience.

[0054] In this embodiment, when starting execution of the operational test mode 312b, the control unit 31 controls the communication unit 33 to notify the external terminal 100 that the operational test mode 312b is being executed. This allows the user to confirm that an automatically executed operational test is being executed.

[0055] In this embodiment, when the control unit 31 receives an operation instruction request for the opening and closing operation of the shutter unit 21 from the user via the reception unit 311 while the operation test mode 312b is being executed, the control unit 31 suspends the operation test and drives the drive unit 23 in accordance with the operation instruction request to open and close the shutter unit 21. This allows the opening and closing operation of the shutter unit 21 even while the operation test mode 312b is being executed, thereby improving convenience.

[0056] The method for diagnosing an abnormality in an electric shutter device of this embodiment is a method for diagnosing an abnormality in an electric shutter device 1 that includes a shutter unit 21 that is capable of opening and closing the opening 12 by being driven by a drive unit 23, and a communication unit 33 that communicates with an external terminal 100, and by executing an operation test mode 312b as a control mode, an operation test is performed for each of a plurality of test items. This makes it possible to perform an abnormality diagnosis at any timing to determine whether the functions of each part of the electric shutter device 1 are normal. When performing the operation test, there is no need to consider effects caused by the field, such as vibrations caused by an overload on the motor, and therefore it is possible to easily determine abnormalities caused by the product.

[0057] In this embodiment, in operation test mode 312b, if the shutter unit 21 is located in a position in the opening direction that is closer to the center of the opening 12 along the opening / closing direction, the shutter unit 21 is operated in the closing direction, and if the shutter unit 21 is located in a position in the closing direction that is closer to the center of the opening 12 along the opening / closing direction, the shutter unit 21 is operated in the opening direction. This makes it possible to prevent an erroneous determination of an abnormality due to an overload on the motor when the shutter unit 21 is opened in a fully open state or closed in a fully closed state.

[0058] In this embodiment, the test results of the operation test mode 312b are transmitted to the external terminal 100. This allows the user to check the test results of the operation test.

[0059] In this embodiment, the electric shutter device 1 is provided with a memory unit 32, and the test results of the operation test mode 312b are stored in the memory unit 32. This allows the user to use the stored test results to predict failures in the electric shutter device 1, for example, by comparing the current test results with past test results.

[0060] In this embodiment, the operation test mode 312b is executed in response to an execution instruction request received from the external terminal 100. This allows the abnormality diagnosis of the electric shutter device 1 to be performed at any timing according to the user's desire.

[0061] In this embodiment, the operation test mode 312b is executed at predetermined intervals or after a predetermined number of opening and closing operations of the shutter unit 21. This allows the operation test to be performed automatically at regular intervals to diagnose abnormalities, eliminating the need for user operation.
