Mode for Carrying Out the Invention

[0015] In the following embodiments and modifications, the same or equivalent components and members are denoted by the same reference numerals, and redundant explanations are omitted as appropriate. Also, the dimensions of the members in each drawing are enlarged or reduced as appropriate for easy understanding. Further, a part of the members that are not important in explaining the embodiment in each drawing is omitted and shown.

[0016] [First Embodiment] Refer to FIG. 1. The automatic door 100 mainly includes a door part 10 that is driven to open and close, a guide mechanism 13 that guides the horizontal movement of the first movable door 11L and the second movable door 11R, a door controller 20 that controls the entire automatic door 100, a door sensor 30 that detects passers-by, a driving part 40 that generates power, and a power transmission part 50 that transmits power to the door part 10. In the following description, the left - right direction in FIG. 1 is the horizontal direction (opening and closing direction), the up - down direction in FIG. 1 is the vertical direction, and the direction orthogonal to the left - right direction and the up - down direction in FIG. 1 is the depth direction. However, the automatic door 100 can be installed in any posture, and its installation direction is not limited to the following examples. In the example of FIG. 1, the opening and closing method shows a double - sliding automatic door, but it is not limited to this. The opening and closing method may be a single - sliding type, a hinged - door type, a folding - door type, a rotating type, etc. The automatic door 100 of this embodiment is an example of an automatic door device. The door controller 20 of this embodiment is an example of a door control device.

[0017] The door part 10 includes a first movable door 11L and a second movable door 11R that are movably provided in the horizontal direction respectively, a first fixed door 12L and a second fixed door 12R that are provided at positions overlapping with the first movable door 11L and the second movable door 11R respectively when the first movable door 11L and the second movable door 11R are in the open state, and a guide mechanism 13 that guides the horizontal movement of the first movable door 11L and the second movable door 11R. When the door part 10 is driven to open, the first movable door 11L shown on the left side in FIG. 1 is driven to the left, and the second movable door 11R shown on the right side in FIG. 1 is driven to the right. Also, when the door part 10 is driven to close, contrary to the opening drive, the first movable door 11L is driven to the right, and the second movable door 11R is driven to the left. Note that the number, shape, etc. of the doors constituting the door part 10 are not limited to the above, and can be appropriately designed according to the needs of the installation location. Similarly, the movable direction of the door part 10 is not limited to the horizontal direction, and may be a direction inclined from the horizontal direction. Hereinafter, the first movable door 11L and the second movable door 11R may be collectively referred to as the movable door 11. The movable door 11 of this embodiment is an example of a door.

[0018] The guide mechanism 13 includes a traveling rail 131, a door hanger 132, and a guide rail 133. The traveling rail 131 is a columnar rail member that extends horizontally above the first and second movable doors 11L and 11R over the entire movable range thereof. A door hanger 132 attached to the upper portions of the first and second movable doors 11L and 11R is suspended from the traveling rail 131. The door hanger 132 is attached to the movable door 11 so as to suspend the movable door 11. The door hanger 132 is configured to be able to travel on the traveling rail 131 while suspending the first and second movable doors 11L and 11R from the traveling rail 131. The guide rail 133 is a groove-shaped rail member that extends horizontally below the first and second movable doors 11L and 11R over the entire movable range thereof. The guide rail 133 guides the first and second movable doors 11L and 11R in the opening and closing directions.

[0019] The door controller 20 can set various parameters related to the opening and closing of the movable door 11. For example, the door controller 20 can adjust set values such as the traveling speed, the opening and closing strength, and the opening width. The traveling speed is the horizontal speed of the first movable door 11L and the second movable door 11R, and the directions of the speeds of both doors are opposite to each other. Also, different values may be set for the traveling speed during normal opening and closing and at other times. For example, in the case of so-called reversal in which, during normal closing drive of the door portion 10, switching to opening drive is performed to urgently avoid a passerby being pinched between the first and second movable doors 11L and 11R that are closing, the speeds of the first and second movable doors 11L and 11R during that opening drive may be set to values different from the speeds during normal opening drive.

[0020] The opening and closing strength is the magnitude of the force when the first and second movable doors 11L and 11R are opened and closed, and is controlled by the generated torque value of the motor 41 of the drive unit 40 described later. Similar to the above-described traveling speed, it is preferably basically the same opening and closing strength for the first and second movable doors 11L and 11R. Also, different opening and closing strengths may be set during normal opening and closing and at other times. The opening width is the horizontal interval between the first movable door 11L and the second movable door 11R when the door portion 10 is fully open.

[0021] Refer to FIG. 2. The door controller 20 includes a control device 21, a storage device 22, a communication device 23, and a detection device 24. The control device 21 is realized by an arithmetic processing unit mounted on a microcontroller and is in charge of various information processing and control in the automatic door 100. The control device 21 controls the drive unit 40 according to the detection results of passers-by and the like from the door sensor 30 to open and close the door portion 10. Further, the control device 21 can open and close the automatic door 100 in response to receiving an opening / closing command signal for opening and closing the automatic door 100 from the worker's work terminal or a remote computer via the communication device 23.

[0022] The storage device 22 is a general-purpose memory that stores various data of the automatic door 100.

[0023] The communication device 23 exchanges various information with external communication devices of the automatic door 100 through wired or wireless connections. For example, the communication device 23 can communicate with a work terminal used by a worker who has come to the site for the installation, maintenance, and inspection of the automatic door 100. Thereby, the worker can check the information of each part of the automatic door 100 on the work terminal and can also input various data of the automatic door 100. When the communication device 23 has a communication function via a public information communication network such as the Internet, information confirmation and data input of the automatic door 100 can be performed from a remote computer.

[0024] The door sensor 30 includes an activation sensor 31 and an auxiliary sensor 32. The activation sensor 31 is a photoelectric sensor provided on the surface of the blind 60 above the door portion 10. The activation sensor 31 includes a light projecting portion that projects light such as infrared rays toward the floor surface and a light receiving portion that detects the reflected light from the floor surface. When a passer-by approaches the automatic door 100 and blocks the light, the amount of light received by the light receiving portion changes, so that the passer-by can be detected. When the detection information by such an activation sensor 31 is input to the door controller 20, the motor 41 is driven to open the door portion 10.

[0025] The auxiliary sensor 32 is a photoelectric sensor provided on the first fixed door 12L and the second fixed door 12R of the door unit 10. The auxiliary sensor 32 includes a light-emitting unit provided on one of the first fixed door 12L and the second fixed door 12R, and a light-receiving unit provided on the other. The light-emitting unit and the light-receiving unit are provided at the same height from the floor surface, and the light-receiving unit detects light such as infrared light emitted horizontally from the light-emitting unit. When the door unit 10 is open and a pedestrian passes through the opening and blocks the light, the amount of light received by the light-receiving unit changes, so that the pedestrian can be detected. The main purpose of the auxiliary sensor 32 is to protect against closure, and when the auxiliary sensor 32 detects a pedestrian during the closing operation of the first and second movable doors 11L and 11R, the control device 21 performs inversion control to stop the closing drive and switch to the opening drive. This makes it possible to prevent a pedestrian from being caught between the first and second movable doors 11L and 11R that are closing.

[0026] The detection device 33 detects operation information of the automatic door 100. The detection device 33 includes a voltage sensor 33a that detects the drive voltage of the motor 41, a current sensor 33b that detects the drive current of the motor 41, and a speed sensor 33c that detects the travel speed of the movable door 11 of the automatic door 100. The detection device 33 is provided outside the door controller 20, but may be provided inside the door controller 20.

[0027] The driving unit 40 includes a motor 41 as a power source that generates rotational power, and a driving pulley 42 that is rotationally driven by the motor 41. The motor 41 can be configured as various known motors, but in this embodiment, as an example, it is a brushless motor equipped with an encoder 41A using a Hall element. The position of the rotor of the motor 41 detected by the encoder 41A is input to the control device 21, and a driving voltage or driving current is applied to the motor 41 in response to the position, thereby generating a desired rotational power. The driving pulley 42 is connected to the rotor of the motor 41 via a gear mechanism or the like (not shown), and rotates in conjunction with the rotor.

[0028] The power transmission unit 50 transmits the power generated by the drive unit 40 to the door unit 10 to drive the first and second movable doors 11L and 11R to open and close. The power transmission unit 50 includes a power transmission belt 51, a driven pulley 52, and a connecting member 53. The power transmission belt 51 is an annular timing belt having a large number of teeth formed on its inner peripheral surface, which is wound around the drive pulley 42 on the right side of FIG. 1 and wound around the driven pulley 52 on the left side of FIG. 1. In this state, the horizontal dimension of the power transmission belt 51 is equal to the horizontal distance between the drive pulley 42 and the driven pulley 52, and is also approximately the same as the horizontal dimension of the movable range of the first and second movable doors 11L and 11R. When the drive pulley 42 rotates by the motor 41, the driven pulley 52 rotates in conjunction via the power transmission belt 51.

[0029] The connecting member 53 connects the first and second movable doors 11L and 11R to the power transmission belt 51 respectively to drive them to open and close. Here, one movable door 11 is connected to the upper side of the power transmission belt 51, and the other movable door 11 is connected to the lower side of the power transmission belt 51. In the example of FIG. 1, when the power transmission belt 51 rotates counterclockwise, the first movable door 11L moves to the left and the second movable door 11R moves to the right for the opening operation. When the power transmission belt 51 rotates clockwise, the first movable door 11L moves to the right and the second movable door 11R moves to the left for the closing operation.

[0030] FIG. 3 is a block diagram schematically showing the functions of the door controller 20 of the present embodiment. Each functional block shown in the following figures is realized by a computer having arithmetic functions, control functions, storage functions, input functions, output functions, various electronic elements, mechanical parts, etc. in terms of hardware, and is realized by a computer program or the like in terms of software. Here, however, functional blocks realized by their cooperation are depicted. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by combinations of hardware and software.

[0031] The door controller 20 includes a command acquisition unit 101, a position information acquisition unit 102, an opening / closing control unit 103, a voltage information acquisition unit 104, a determination unit 105, an output unit 106, and a storage unit 107. The command acquisition unit 101 acquires an opening command or a closing command for the movable door 11 from, for example, a worker's work terminal or the like. The position information acquisition unit 102 acquires a pulse signal from the encoder 41A as position information indicating the rotational position (door position) of the motor 41. The opening / closing control unit 103 controls the drive unit 40 based on the position information supplied from the position information acquisition unit 102 to move the movable door 11 in the opening / closing direction, thereby controlling the opening and closing of the movable door 11. The voltage information acquisition unit 104 acquires voltage information indicating the output voltage of the AC power input capacitor 72A when at least one of the opening operation or the closing operation of the movable door 11 is executed by the opening / closing control unit 103. The determination unit 105 determines the degree of deterioration of the AC power input capacitor 72A based on the voltage information. The output unit 106 outputs the determination result of the degree of deterioration of the AC power input capacitor 72A. The storage unit 107 stores various data such as voltage information, various threshold values, and operation information of the automatic door 100 (for example, drive voltage, drive current, energization time, opening / closing times of the motor 41).

[0032] In the door controller 20, the AC power supply 81 is connected to the converter circuit 71, and an AC power input capacitor 72A, which is a smoothing capacitor, is connected to the output of the converter circuit 71. A DC power supply is formed by smoothing the waveform of the voltage output from the AC power supply 81 via the converter circuit 71 by the AC power input capacitor 72A. The opening / closing control unit 103 performs PWM control on the inverter circuit 73 using the DC power supply. The output of the inverter circuit 73 is supplied to the motor 41, whereby the motor 41 is rotationally driven. The pulse signal of the encoder 41A of the motor 41 is supplied to the opening / closing control unit 103 via the position information acquisition unit 102 as position information indicating the rotational position (door position) of the motor 41. The opening / closing control unit 103 controls the driving of the motor 41 based on this position information.

[0033] Also, the output terminal of the AC power input capacitor 72A is connected to the primary side terminal of the transformer 75 via the power control unit 74. The power control unit 74 controls the on / off of the current flowing through the transformer 75 based on the detected voltage of the voltage detection unit 77 (the relative voltage between the terminals of the voltage detection unit) so that the voltage supplied to the transformer 75 becomes a predetermined voltage. A transformer output capacitor 72B, which is a smoothing capacitor, is connected to the secondary side terminal of the transformer 75 via the power generation unit 76. The power generation unit 76 generates a DC voltage from the voltage supplied from the transformer 75. The transformer output capacitor 72B smoothes the waveform of the DC voltage supplied from the transformer 75 via the power generation unit 76 and outputs the smoothed voltage to the peripheral device 82. The peripheral device 82 is, for example, various sensors such as the door sensor 30 and the detection device 33.

[0034] Using FIG. 4, the processing of the door controller 20 of the present embodiment will be described. FIG. 4 is a flowchart showing the processing S100 of the door controller 20 of the present embodiment. Hereinafter, the processing at the timing of acquiring an opening command from the state where the movable door 11 is fully closed will be exemplified by extraction. The processing S100 is repeatedly executed every fixed period (for example, 10 milliseconds).

[0035] In step S101, the command acquisition unit 101 determines whether an opening command for the movable door 11 has been acquired. In the present embodiment, the command acquisition unit 101 receives an opening command from an external device such as a worker's work terminal (not shown). If the opening command has not been acquired (N in step S101), the processing S100 ends. If the opening command has been acquired (Y in step S101), the command acquisition unit 101 supplies the opening command to the opening / closing control unit 103, and the processing S100 proceeds to step S102.

[0036] In step S102, the opening / closing control unit 103 drives the movable door 11 to open in response to the opening command. The opening / closing control unit 103 supplies a voltage information acquisition command to the voltage information acquisition unit 104, and the processing S100 proceeds to step S103.

[0037] In step S103, the voltage information acquisition unit 104 acquires voltage information when the opening drive of the movable door 11 is executed. In the present embodiment, the voltage information acquisition unit 104 acquires, as voltage information, the output voltage of the AC power input capacitor 72A when the movable door 11 is in an acceleration control operation of accelerating to the first speed.

[0038] Here, with reference to FIGS. 5 and 6, the relationship between the running speed of the movable door 11 and the voltage of the capacitor in the door controller 20 will be described. First, the opening operation of the movable door 11 of the present embodiment will be described with reference to FIG. 5. The opening operation of the movable door 11 of the present embodiment includes an acceleration control operation of accelerating the movable door 11 stopped at the closed position to a predetermined first speed V1, a high-speed control operation of maintaining the first speed V1, a deceleration control operation of decelerating to a second speed V2, a low-speed control operation of maintaining the second speed V2, and a door hitting operation of bringing the movable door 11 into contact with a stopper (not shown) to stop it. In the acceleration control operation, when the running speed reaches the first speed V1, the operation is switched to the high-speed mode operation. In the high-speed control operation, when the stroke value of the movable door 11 reaches a predetermined value, the operation is switched to the deceleration control operation. In the deceleration control operation, when the running speed reaches the second speed V2, the operation is switched to the low-speed control operation. In the low-speed control operation, the movable door 11 is moved to the open position. When the movable door 11 reaches the open position, by the door hitting operation, the movable door 11 comes into contact with the stopper and stops.

[0039] With reference to FIG. 5, the average voltage of the capacitor during the opening operation will be described. In FIG. 5, the average voltage E2 indicates the average voltage of a capacitor with less deterioration, and the average voltage E3 indicates the average voltage of a capacitor with greater deterioration. The average voltage here is, for example, the average value of the voltage of the capacitor over a predetermined period (for example, a half cycle of the AC power supply voltage). In the acceleration control operation in which the movable door 11 accelerates to the first speed V1, as shown by the average voltages E2 and E3 in FIG. 5, the average voltage of the capacitor temporarily decreases to a minimum value and then increases to a predetermined value. In the acceleration control operation, the minimum value of the average voltage E3 is smaller than the minimum value of the average voltage E2.

[0040] FIG. 6 shows the voltage change of the capacitor in a minute time interval R1 during the acceleration control operation. FIG. 6 shows the voltage in the time interval R1 corresponding to 1.5 cycles of the AC power supply voltage E6 of the AC power supply 81 during the acceleration control operation. In FIG. 6, the voltage E1 indicates the voltage in a state where the automatic door 100 is not being driven, the voltage E4 indicates the voltage for a capacitor with little deterioration, and the voltage E5 indicates the voltage for a capacitor with significant deterioration. E2 and E3 are as described above.

[0041] As shown by the voltages E5 and E6, during the acceleration control operation, a large amount of power is suddenly required in the motor 41, and the power stored in the capacitor is discharged to suppress the current change at this time, causing the voltage of the capacitor to drop. Here, when the capacitance of the capacitor decreases due to its deterioration, its power storage capacity decreases, so that the sudden current change during the acceleration control operation cannot be sufficiently suppressed by the discharge. As a result, the degree of voltage drop of the voltage E5 for a capacitor with significant deterioration is greater than that of the voltage E4 for a capacitor with little deterioration. From the above, in the acceleration control operation, the average voltage E3 is smaller than the average voltage E2. The voltage information acquisition unit 104 supplies the acquired voltage information to the determination unit 105, and the process S100 proceeds to step S104.

[0042] In step S104, the determination unit 105 determines the degree of deterioration of the AC power supply input capacitor 72A based on the voltage information. In the present embodiment, the storage unit 107 stores the voltage information acquired at the time of installation of the automatic door 100, and the determination unit 105 determines the degree of deterioration of the AC power supply input capacitor 72A based on the voltage information acquired at the time of installation of the automatic door 100. For example, the determination unit 105 calculates a value serving as an index of the degree of deterioration of the AC power supply input capacitor 72A based on the degree of deviation (such as difference or ratio) of the minimum value of the average voltage of the AC power supply input capacitor 72A in the acceleration control operation in the voltage information acquired in step S103 with respect to the minimum value of the average voltage of the AC power supply input capacitor 72A in the acceleration control operation in the voltage information acquired at the time of installation of the automatic door 100, and uses this as the determination result. The determination unit 105 supplies the determination result to the output unit 106.

[0043] In step S105, the output unit 106 outputs the determination result. In the present embodiment, the output unit 106 transmits the determination result to, for example, the worker's work terminal via the communication device 23. As a result, the determination result of the degree of deterioration of the AC power input capacitor 72A can be presented on the display screen of the work terminal or the like and can be utilized for the maintenance of the automatic door 100. For example, the worker can propose the replacement recommendation of the door controller 20 and the like. After step S105, the process S100 ends.

[0044] Hereinafter, the operation and effects of the present embodiment will be described.

[0045] As a typical failure of the automatic door 100, there is a failure due to the deterioration (such as drying up) of the AC power input capacitor 72A of the door controller 20. When the deterioration of the AC power input capacitor 72A progresses, there are many cases where the door controller 20 fails without warning and suddenly stops operating.

[0046] On the contrary, in the present embodiment, based on the voltage information of the AC power input capacitor 72A, the degree of deterioration of the AC power input capacitor 72A is determined. According to this configuration, since it is possible to appropriately determine the degree of deterioration of the AC power input capacitor 72A, it is possible to suppress the occurrence of a situation where the door controller 20 suddenly fails and the automatic door 100 cannot be used.

[0047] In the present embodiment, the voltage information acquisition unit 104 acquires the voltage of the AC power input capacitor 72A when the movable door 11 is in the acceleration control operation of accelerating to the first speed V1. According to this configuration, in the acceleration control operation, since the voltage fluctuation of the AC power input capacitor 72A appears significantly due to the deterioration of the AC power input capacitor 72A, it is possible to more accurately determine the degree of deterioration of the AC power input capacitor 72A.

[0048] In this embodiment, the determination unit 105 determines the degree of deterioration of the AC power input capacitor 72A based on the voltage information acquired during the installation of the automatic door 100. According to this configuration, by using the voltage information in a state where the deterioration of the AC power input capacitor 72A is extremely small during the installation of the automatic door 100 as a reference, the degree of deterioration can be determined more accurately.

[0049] In this embodiment, the output unit 106 outputs the determination result of the degree of deterioration of the AC power input capacitor 72A. According to this configuration, since the degree of deterioration of the AC power input capacitor 72A can be grasped, appropriate maintenance can be performed.

[0050] Hereinafter, a modification example of this embodiment will be described.

[0051] In the embodiment, voltage information is acquired when the opening drive is executed in response to an opening command, but it is not limited to this. For example, voltage information may be acquired when the opening drive is executed in response to the detection information of the activation sensor 31.

[0052] In the embodiment, the degree of deterioration of the AC power input capacitor 72A is determined based on the voltage information of the AC power input capacitor 72A, but it is not limited to this. For example, the degree of deterioration of the transformer output capacitor 72B may be determined based on the voltage information of the transformer output capacitor 72B. When the transformer output capacitor 72B deteriorates and malfunctions, peripheral devices 82 such as the door sensor 30 do not function properly, and as a result, the automatic door 100 does not function properly. By determining the degree of deterioration of the transformer output capacitor 72B, it is possible to suppress the situation where the peripheral devices 82 do not function properly and the automatic door 100 does not function properly. Note that it is not limited to the AC power input capacitor 72A and the transformer output capacitor 72B, and any capacitor voltage information provided in the door controller 20 may be used. Hereinafter, the capacitors provided in the door controller 20 may be collectively referred to as the capacitor 72.

[0053] In the embodiment, voltage information is acquired when the opening drive is executed, but the present invention is not limited to this, and voltage information may be acquired when the closing drive is executed.

[0054] In the embodiment, voltage information during the acceleration control operation is acquired, but the present invention is not limited to this, and voltage information during the deceleration control operation (see FIG. 5) in which the movable door 11 is decelerated to a second speed V2 lower than the first speed V1 may be acquired. Refer to FIGS. 5 and 7. As shown in FIGS. 5 and 7, in the deceleration control operation, the maximum value of the average voltage E3 is larger than the maximum value of the average voltage E2. In the deceleration control operation, regenerative power is generated in the motor 41 as the deceleration occurs and is supplied to the capacitor 72. Here, when the capacitance of the capacitor 72 decreases due to its deterioration, the stored charge decreases. As a result, the degree of voltage increase of the voltage E5 for the capacitor with large deterioration is greater than that of the voltage E4 for the capacitor with small deterioration. From the above, in the deceleration control operation, the average voltage E3 becomes smaller than the average voltage E2. Therefore, it is possible to determine the degree of deterioration of the capacitor 72 by obtaining the above deviation degree using the voltage information acquired in the deceleration control operation.

[0055] In the embodiment, the determination unit 105 determines the degree of deterioration based on the degree of deviation between the voltage information acquired in step S103 and the voltage information at the time of installation of the automatic door 100, but the present invention is not limited to this. For example, the determination unit 105 may determine the degree of deterioration based on the degree of deviation between the voltage information acquired in step S103 and a predetermined reference value or the voltage information at the time of safety inspection of the automatic door 100.

[0056] In the embodiment, voltage information when the movable door 11 is actually driven to open is acquired by driving the movable door 11 to open, but the present invention is not limited to this. For example, the voltage information may be acquired by reading from the storage unit 107 the voltage information when the movable door 11 was driven most recently without driving the movable door 11. Further, in the above-described door contact operation, control may be performed to continuously drive and press the movable door 11 in the closing direction so that the movable door 11 does not open due to some factor even when the movable door 11 is stopped at the fully closed position. Also in this pressing control, the voltage of the AC power input capacitor 72A decreases, and thus the degradation of the AC power input capacitor 72A may be determined using the voltage information during this pressing control.

[0057] Refer to FIG. 8. An operation information acquisition unit 108 that acquires operation information of the automatic door 100 may be provided. In this case, the determination unit 105 may further determine the degree of degradation of the capacitor based on the operation information. The operation information of the automatic door 100 here is, for example, the drive voltage, drive current, energization time per drive, and number of opening and closing operations of the motor 41. When the AC power input capacitor 72A of the automatic door 100 is degraded, the expected opening and closing drive cannot be performed with the normal drive voltage or drive current, so the drive voltage or drive current becomes excessive or too small through a control loop or the like, and the degradation of the AC power input capacitor 72A can be detected. Also, when the AC power input capacitor 72A of the automatic door 100 is degraded, the expected opening and closing drive cannot be performed, so the energization time of the motor 41 per drive becomes longer than normal, and the degradation of the AC power input capacitor 72A can be detected. Further, the greater the number of opening and closing operations, the greater the load on the AC power input capacitor 72A, so the AC power input capacitor 72A is more likely to degrade, and thus the degradation of the AC power input capacitor 72A can also be detected based on the number of opening and closing operations.

[0058] In addition, the operation information acquisition unit 108 may acquire the operation information of the peripheral device 82 that is connected to the automatic door 100 and powered by the automatic door 100. The operation information of the peripheral device 82 here is, for example, the number of operations of the peripheral device 82. When the peripheral device 82 is various sensors 33a to 33c of the door sensor 30 or the detection device 33, it is the detection intensity of the sensor (in the case of a photoelectric sensor, it is the amount of received light), the energization time of the sensor per detection, and the like. The more the number of operations of the peripheral device 82, the greater the load on the transformer output capacitor 72B, and the easier it is for the transformer output capacitor 72B to deteriorate. Therefore, the deterioration of the transformer output capacitor 72B can also be detected based on the number of operations. When the transformer output capacitor 72B is deteriorated, the voltage supplied to the sensor (peripheral device 82) becomes unstable and the sensor cannot perform the intended detection operation. Therefore, the energization time of the sensor per detection becomes longer than normal, and the deterioration of the transformer output capacitor 72B can be detected.

[0059] In summary, the operation information acquisition unit 108 may acquire the operation information of at least one of the automatic door 100 and the peripheral device 82 that is connected to the automatic door 100 and powered by the automatic door 100. According to this configuration, since the degree of deterioration of the capacitor also varies depending on the operation status of the automatic door 100 and the peripheral device 82, the degree of deterioration can be determined more accurately based on the operation information.

[0060] Refer to FIG. 9. The door controller 20 may include an environmental information acquisition unit 109 that acquires environmental information including at least one of the temperature, humidity, and atmospheric pressure around the automatic door 100. In this case, the determination unit 105 may determine the degree of deterioration of the capacitor 72 based further on the environmental information. For example, the environmental information acquisition unit 109 acquires environmental information from a temperature sensor, a humidity sensor, and an atmospheric pressure sensor provided around the automatic door 100. For example, the storage unit 107 stores scores assigned for each range of the temperature, humidity, and atmospheric pressure around the automatic door 100 (for example, 10 points for a temperature of 10°C to 15°C, 11 points for a temperature of 15°C to 20°C, 10 points for a humidity of 50% to 60%, 11 points for a humidity of 60% to 70%, 10 points for an atmospheric pressure of 0.9 to 1 atm, 11 points for an atmospheric pressure of 1 atm to 1.1 atm, etc.). For example, when the score assigned to the range corresponding to the average value of the environmental information from the time of installation of the automatic door 100 to the present exceeds a predetermined standard, the determination unit 105 may multiply the voltage information by a predetermined constant greater than 1 to increase the absolute value of the voltage information and weight it. The capacitor 72 is also affected by the temperature, humidity, and atmospheric pressure around the automatic door 100. For example, the greater the temperature and humidity in the environment around the automatic door 100, or the smaller the atmospheric pressure, the greater the degree of deterioration of the capacitor 72. By further basing on the environmental information, it becomes possible to accurately determine the degree of deterioration of the capacitor 72.

[0061] [Second Embodiment] Hereinafter, a second embodiment of the present invention will be described. In the drawings and description of the second embodiment, the same or equivalent components and members as those in the first embodiment are denoted by the same reference numerals. Descriptions overlapping with those of the first embodiment are appropriately omitted, and the configurations different from those of the first embodiment will be mainly described.

[0062] In the first embodiment, the determination result of the degree of deterioration was a value serving as an index of the degree of deterioration of the AC power input capacitor 72A, but it is not limited thereto. In the second embodiment, the determination result of the degree of deterioration indicates whether the AC power input capacitor 72A is deteriorated.

[0063] Using FIG. 10, the processing of the door controller 20 of the second embodiment will be described. FIG. 10 is a flowchart showing the processing S200 of the door controller 20 of the second embodiment. Since steps S201 to S203 in processing S200 are the same as S101 to S103 in processing S100, their descriptions will be omitted.

[0064] After executing steps S201 to S203, in step S204, the determination unit 105 determines whether the AC power input capacitor 72A is deteriorated based on the voltage information. For example, the determination unit 105 determines whether the degree of deterioration determined based on the voltage information exceeds a predetermined reference value, and determines that the capacitor 72 is deteriorated when it exceeds the predetermined reference value. If the capacitor 72 is not deteriorated (N in step S204), the processing S200 ends. If the capacitor 72 is deteriorated (Y in step S204), the determination unit 105 supplies the determination result indicating deterioration to the opening / closing control unit 103, and the processing S200 proceeds to step S205.

[0065] In step S205, the opening / closing control unit 103 changes the traveling speed of the movable door 11 in the opening / closing control to a traveling speed lower than the traveling speed of the movable door 11 in the normal opening / closing control. By making the traveling speed of the movable door 11 lower than normal, it becomes possible to make the voltage fluctuation applied to the AC power input capacitor 72A of the door controller 20 smaller than normal. Therefore, it is possible to suppress the deterioration of the AC power input capacitor 72A and thereby suppress the failure of the door controller 20. After step S205, the processing S200 ends.

[0066] In the second embodiment, in step S205, the opening / closing control unit 103 changes the traveling speed of the movable door 11 in the opening / closing control of the movable door 11 to a traveling speed lower than the traveling speed of the movable door 11 in the normal opening / closing control, but it is not limited to this. The opening / closing control unit 103 may change the driving force in the opening / closing control of the movable door 11 to a driving force smaller than the driving force in the normal opening / closing control.

[0067] In addition, when it is determined that the capacitor 72 is deteriorated, the output unit 106 may transmit the deterioration determination result to the worker's work terminal, or may notify that the capacitor 72 is deteriorated by causing an LED (such as the LED used in the door sensor 30) mounted on the automatic door 100 to blink in a specific pattern. Further, the output unit 106 may generate a buzzer sound from a sound source device (not shown) mounted on the automatic door 100.

[0068] [Third Embodiment] Hereinafter, a third embodiment of the present invention will be described. In the drawings and description of the third embodiment, the same or equivalent components and members as those in the first embodiment are denoted by the same reference numerals. Descriptions overlapping with those in the first embodiment are omitted as appropriate, and configurations different from those in the first embodiment will be mainly described.

[0069] In the first embodiment, the degree of deterioration of the capacitor 72 is determined based on voltage information, but the present invention is not limited to this. In the second embodiment, the degree of deterioration of the capacitor 72 is determined based on temperature transition information indicating the transition of the temperature of the capacitor 72.

[0070] FIG. 11 is a block diagram schematically showing the functions of the door controller 20 according to the second embodiment. The door controller 20 according to the second embodiment includes a temperature transition information acquisition unit 110 instead of the voltage information acquisition unit 104 in the first embodiment.

[0071] The temperature transition information acquisition unit 110 acquires temperature transition information indicating the transition of the temperature of the capacitor 72 included in the door controller 20. In the present embodiment, temperature transition information regarding the transformer output capacitor 72B is acquired. The temperature sensor 83 in the present embodiment measures the temperature of the transformer output capacitor 72B. The storage unit 107 stores the measured value of the temperature sensor 83 in association with the measurement time. The temperature transition information acquisition unit 110 acquires the temperature transition information by reading the temperature of the transformer output capacitor 72B stored in the storage unit 107 in association with the measurement time. The determination unit 105 determines the degree of deterioration of the transformer output capacitor 72B based on the temperature transition information.

[0072] In addition, the storage unit 107 of the present embodiment stores the standard value of the lifetime of the capacitor 72 in a specific temperature range of the capacitor 72 (hereinafter referred to as the standard lifetime), and the standard value of the lifetime consumption per unit time (for example, per hour) of the capacitor 72 for each temperature range of the capacitor 72 calculated from the standard lifetime (hereinafter referred to as the standard lifetime consumption). The standard lifetime is determined by the specifications of the capacitor 72. For example, as shown in FIG. 12, for a certain type of capacitor C1, the standard lifetime is set to 5000 hours at 105° C. When 1 hour has elapsed at 105° C., 1 / 5000 of the standard lifetime is consumed. Also, for another type of capacitor C2, the standard lifetime is set to 2000 h at 85° C. When 1 hour has elapsed at 85° C., 1 / 2000 of the standard lifetime is consumed. The storage unit 107 stores a data table showing the relationship between the standard lifetime and the standard lifetime consumption for each temperature range of the capacitor as shown in FIG. 12.

[0073] The processing of the door controller 20 of the second embodiment will be described with reference to FIG. 13. FIG. 13 is a flowchart showing the processing S300 of the door controller 20 of the third embodiment.

[0074] In step S301, the command acquisition unit 101 acquires a determination command for the degree of deterioration of the transformer output capacitor 72B of the door controller 20. In the present embodiment, the command acquisition unit 101 receives a determination command from an external device such as a worker's work terminal. If the determination command has not been acquired (N in step S301), the process S100 ends. If the determination command has been acquired (Y in step S301), the command acquisition unit 101 supplies the acquired command to the temperature transition information acquisition unit 110, and the process S300 proceeds to step S302.

[0075] In step S302, the temperature change information acquisition unit 110 acquires temperature change information indicating the change in the temperature of the transformer output capacitor 72B over a predetermined period. This predetermined period can be, for example, the period from the time of installation of the automatic door 100 to the present, or the period from the completion of the security inspection of the automatic door 100 to the present. The temperature change information acquisition unit 110 supplies the acquired temperature change information to the determination unit 105, and the process S300 proceeds to step S303.

[0076] In step S303, the determination unit 105 determines the degree of degradation of the transformer output capacitor 72B based on the temperature change information. Using FIG. 14, the specific determination process of step S303 will be described.

[0077] In step S311, the determination unit 105 calculates the average temperature for each time zone (for example, a one-hour time zone such as 1:00 to 2:00) for each day based on the temperature change information. For example, in the examples shown in FIGS. 15 and 16, the average temperature for each hour from 1:00 to 24:00 is calculated. Note that in FIGS. 15 and 16, for the sake of simplicity, an example where the above-mentioned predetermined period is one day is shown, but in actuality, the average temperature for each time zone corresponding to the number of days of the above-mentioned predetermined period, such as one month, half a year, or one year, is calculated.

[0078] In step S312, the determination unit 105 applies the temperature range corresponding to the average temperature to each time zone of each day. As shown in FIG. 16, for example, in the time zone from 1:00 to 2:00, since the average temperature is 30°C, the temperature range of 26 to 30°C is assigned. Also, for example, in the time zone from 10:00 to 11:00, since the average temperature is 41°C, the temperature range of 41 to 45°C is assigned. This applied temperature range is an example of the temperature of the capacitor 72 specified by the determination unit 105.

[0079] In step S313, the determination unit 105 specifies the life consumption amount for each time zone of each day based on the applied temperature range. For example, the determination unit 105 reads out the standard life consumption amount for each temperature range of the transformer output capacitor 72B from the storage unit 107, and specifies the life consumption amount corresponding to the applied temperature range. In the example of FIG. 16, since the temperature range of 26 to 30 °C is assigned to the time zone from 1:00 to 2:00, the determination unit 105 specifies 1 / 960000 of the standard life time as the life consumption amount, and since the temperature range of 41 to 45 °C is assigned to the time zone from 10:00 to 11:00, the determination unit 105 specifies 1 / 320000 of the standard life time as the life consumption amount.

[0080] In step S314, the determination unit 105 calculates the cumulative value of the life consumption amount for the entire predetermined period by integrating the life consumption amount for each time zone of each day. For example, in the example of FIG. 16, the life consumption amount per hour from 24:00 to 4:00 and from 21:00 to 24:00 is 1 / 960000 respectively, the life consumption amount per hour from 4:00 to 7:00 and from 18:00 to 21:00 is 1 / 640000 respectively, the life consumption amount per hour from 7:00 to 10:00 and from 16:00 to 18:00 is 1 / 480000 respectively, and the life consumption amount per hour from 10:00 to 16:00 is 1 / 320000 respectively. Therefore, the cumulative value of the life consumption amount in the example of FIG. 16 is (1 / 960000×7)+(1 / 640000×6)+(1 / 480000×5)+(1 / 320000×6)=11 / 240000. Therefore, in the example of FIG. 16, the cumulative value of the life consumption amount for the entire predetermined period is 11 / 240000 of the standard life time.

[0081] In step S315, the determination unit 105 determines the degree of degradation of the transformer output capacitor 72B based on the cumulative value of the life consumption amount over the entire predetermined period. The determination unit 105 may generate a determination result using the numerical value itself calculated as the cumulative value of the life consumption amount over the entire predetermined period as an index indicating the degree of degradation of the transformer output capacitor 72B, or may generate a determination result indicating whether the transformer output capacitor 72B is degraded based on the comparison result between the numerical value calculated as the cumulative value and a threshold value. The determination unit 105 supplies the determination result of the degree of degradation of the transformer output capacitor 72B to the output unit 106.

[0082] Returning to FIG. 13, in step S304, the output unit 106 outputs the determination result of the degree of degradation of the transformer output capacitor 72B. Since step S304 is basically the same as step S105, the description thereof is omitted. After step S304, the process S300 ends.

[0083] As described above, in the third embodiment, the degree of degradation of the transformer output capacitor 72B is determined based on the temperature transition information of the transformer output capacitor 72B. According to this configuration, since the consumption amount of the life time of the transformer output capacitor 72B can be grasped based on the transition of the temperature, the degree of degradation of the transformer output capacitor 72B can be accurately determined.

[0084] Also, in the third embodiment, the determination unit calculates the cumulative value of the consumption amount of the life time of the capacitor 72 based on the temperature transition information and the standard life consumption amount for each temperature of the capacitor 72, and determines the degree of degradation of the capacitor 72 based on this cumulative value. According to this configuration, since the transition of the temperature of the capacitor 72 can be appropriately reflected in the degree of degradation of the capacitor 72, the degree of degradation of the transformer output capacitor 72B can be accurately determined.

[0085] In the third embodiment, the degree of deterioration of the transformer output capacitor 72B is determined based on the temperature transition information of the transformer output capacitor 72B, but it is not limited thereto. The degree of deterioration of the other capacitor 72 such as the AC power input capacitor 72A may be determined based on the temperature transition information of the other capacitor 72. In this case, the temperature sensor may detect the temperature of the capacitor 72 to be determined.

[0086] In the third embodiment, the average temperature of the capacitor 72 is calculated for each time period, but it is not limited thereto. For example, the average temperature of the capacitor 72 over the entire predetermined period may be calculated, and the life consumption amount may be calculated based on this average temperature. In the third embodiment, the determination unit 105 specifies the applied temperature range as the temperature of the capacitor 72, but it is not limited thereto. For example, the determination unit 105 may specify the average temperature of the capacitor 72 over the entire predetermined period as the temperature of the capacitor 72.

[0087] In the third embodiment, the operation information acquisition unit 108 shown in FIG. 8 may be provided. In this case, for example, when the operation information exceeds a predetermined standard, such as when the number of opening and closing operations or the number of operating times exceeds a predetermined number, the determination unit 105 multiplies by a predetermined coefficient to weight so as to increase the life consumption amount, and determines the degree of deterioration of the capacitor using the weighted life consumption amount.

[0088] Similarly, in the third embodiment, the environment information acquisition unit 109 shown in FIG. 9 may be provided. In this case, for example, when the score obtained based on the environment information exceeds a predetermined standard, the determination unit 105 multiplies by a predetermined coefficient to weight so as to increase the life consumption amount, and determines the degree of deterioration of the capacitor using the weighted life consumption amount.

[0089] The memory unit 107 may store a learned model for determining the degree of deterioration of the capacitor 72. In this case, the determination unit 105 may determine the degree of deterioration of the capacitor 72 using this learned model. This learned model is an AI model generated by machine learning based on the measured data of the degree of deterioration of the capacitor 72 corresponding to at least one of the voltage information and temperature transition information acquired in advance (for example, the measured data of the degree of deterioration of the capacitor 72 obtained from the measured value of the capacitance of the capacitor 72). This learned model can be generated using known machine learning methods such as support vector machines, neural networks (including deep learning), and random forests. This learned model outputs, as output data, the degree of deterioration of the capacitor 72 corresponding to the input data based on the input data. For example, this learned model includes at least one of the voltage information and temperature transition information as input data, and further includes at least one of the standard life time, standard life consumption, air temperature, humidity, atmospheric pressure, drive voltage of the motor 41, drive current, energization time per drive, number of opening and closing operations, number of operation times of the peripheral device 82, and when the peripheral device 82 is a door sensor 30 or the like, the detection intensity of the sensor and the energization time per detection as input data. By using the learned model, it is advantageous for speeding up data processing and high determination accuracy can be obtained.

[0090] [Fourth Embodiment] Hereinafter, a fourth embodiment of the present invention will be described. In the drawings and description of the fourth embodiment, the same or equivalent components and members as those in the first embodiment are denoted by the same reference numerals. Descriptions overlapping with those of the first embodiment are appropriately omitted, and the configurations different from those of the first embodiment will be mainly described.

[0091] Referring to FIG. 17, the door management system 1 will be described. FIG. 17 is a functional block diagram of the door controller 20 of the automatic door 100 and the door management device 200 according to the present embodiment. The door management system 1 includes a door management device 200 and a plurality of automatic doors 100. The door management device 200 is connected to the plurality of automatic doors 100. The door management device 200 and each automatic door 100 can communicate with each other. For example, the door management device 200 transmits a voltage information acquisition command to each automatic door 100. The door controller 20 of each automatic door 100 can transmit voltage information and the like to the door management device 200.

[0092] The door controller 20 includes a command acquisition unit 101, a voltage information acquisition unit 104, an output unit 106, and a storage unit 107. The door management device 200 includes a command transmission unit 201, a reception unit 202, a door identification unit 203, a determination unit 204, an output unit 205, and an operation condition storage unit 206. The determination unit 204 of the door management device 200 determines the degree of deterioration of the capacitor based on the voltage information of the plurality of automatic doors 100.

[0093] The operation condition storage unit 206 centrally records the operation conditions of the plurality of automatic doors 100A to 100N. The above-mentioned "operation information" is information associated with the actual operation of the door controller 20 of the automatic door 100, etc., while the "operation conditions" are information regarding the prerequisite conditions when operating the automatic door 100. The data constituting the operation conditions are roughly classified into the following four types. (1) Installation environment data (2) Unique data (3) Setting data (4) Operation history data

[0094] The installation environment data refers to data related to the area where the automatic door 100 is installed, data related to the building or facility where the automatic door 100 is installed, and other data related to the installation environment of the automatic door 100. The data related to the installation area includes, for example, meteorological data such as the temperature, humidity, temperature difference between day and night, wind speed, wind direction, precipitation, and sunshine in that area, data on the disaster history and risk of natural disasters such as typhoons and earthquakes, and data on geography and terrain such as being close to the sea or mountains. Also, the data related to the building or facility where the automatic door 100 is installed includes, for example, the construction method and structure of the building, the installation floor number of the automatic door, the floor plan of the floor where the automatic door is installed, the materials of the floor, wall, and ceiling surfaces at the automatic door installation location, the air conditioning and sunshine conditions at the automatic door installation location, and the type of facility (hospital, school, etc.).

[0095] The unique data refers to data related to the model number and specifications of the automatic door 100 or its components, data related to the installation time and method of the automatic door, etc. The specifications of the automatic door 100 include various data, but the weight, dimensions, shape, and material of the door are particularly important. As for the installation time of the automatic door 100, in addition to the date of first installation, the dates of replacement and repair can also be recorded. As for the data related to the installation method of the automatic door 100, the installation direction of the automatic door 100, the mounting height from the floor of the activation sensor 31 and the auxiliary sensor 32, etc. can be recorded.

[0096] The setting data refers to the set values related to the opening and closing drive of the automatic door 100, the set values related to the detection of pedestrians by the automatic door 100, etc. Examples of the set values related to the opening and closing drive include the opening and closing speed, opening and closing strength, and opening width of the movable door 11 described above. Also, examples of the set values related to the detection of pedestrians by the automatic door include the detection sensitivities of the activation sensor 31 and the auxiliary sensor 32. Here, the detection sensitivity is set by the threshold value of the received light amount for determining that a pedestrian has been detected. When the threshold value is small, the detection sensitivity is high, and it is determined that detection has occurred even with a small received light amount. Conversely, when the threshold value is large, the detection sensitivity is low, and it is not determined that detection has occurred with a small received light amount.

[0097] The operation history data refers to the number of past opening and closing operations of the automatic door 100, the past operation rate of the automatic door 100, etc. The number of past opening and closing operations may be the cumulative number since installation, or the cumulative number within a certain past period. Also, it is preferable to record separately the number of normal opening and closing operations and the number of times of inversion to opening drive during closing drive. This is because the inversion operation places a greater burden on the automatic door 100 compared to normal opening and closing operations, and automatic doors with a large number of inversion times need to be preferentially maintained and inspected. The past operation rate can be recorded, for example, as the number of opening and closing operations per day.

[0098] The recording of the operation conditions of each automatic door 100 as described above is performed, for example, as follows. Since "installation environment data" and "unique data" are often data that basically do not change after the automatic door 100 is installed, these data are collectively recorded in the operation condition storage unit 206 of the door management device 200 at the time of installation of the automatic door 100. The recording work may be performed manually via, for example, the operator's work terminal, or may be automatically input without human intervention depending on the item. Data that changes after installation, such as weather data included in the installation environment data, disaster history data of natural disasters, and risk data, are updated as needed. Since these are data not directly related to the automatic door, they can be easily obtained through the Internet or the like. Also, when the unique data changes due to, for example, replacement of parts or adjustment of the installation method, it can be updated as appropriate.

[0099] The "setting data" is recorded by an operator or the like as the initial setting data at the time of installation of the automatic door. When the setting data is changed after installation, the operation conditions are updated based on it. The "operation history data" is recorded in the operation condition storage unit 206 by being provided to the door management device 200 via the output unit 106 of each automatic door 100.

[0100] The door identification unit 203 identifies a plurality of automatic doors 100 under approximate operating conditions based on the operating conditions of each automatic door 100 stored in the operating condition storage unit 206. Specifically, it identifies the automatic door 100 subject to deterioration determination specified via a user input unit (not shown) of the door management device 200, a work terminal, etc., and other automatic doors 100 under approximate operating conditions thereof.

[0101] FIG. 18 is a sequence diagram of the process S400 by the door controller 20 and the door management device 200 of the present embodiment.

[0102] In step S401, the command transmission unit 201 of the door management device 200 transmits an acquisition command for voltage information to each door controller 20. In the present embodiment, for example, in response to receiving a user input for designating the automatic door 100 subject to deterioration determination via the user input unit (not shown) of the door management device 200 from a worker, the command transmission unit 201 of the door management device 200 transmits an acquisition command to each door controller 20.

[0103] In step S402, the command acquisition unit 101 of the door controller 20 receives the acquisition command. The command acquisition unit 101 supplies the received acquisition command to the voltage information acquisition unit 104, and the process S400 proceeds to step S403.

[0104] In step S403, the voltage information acquisition unit 104 of the door controller 20 acquires voltage information respectively. The voltage information acquisition unit 104 supplies the acquired voltage information to the output unit 106, and the process S400 proceeds to step S404.

[0105] In step S404, the output unit 106 of the door controller 20 outputs (transmits) the voltage information to the door management device 200.

[0106] In step S405, the reception unit 202 of the door management device 200 receives voltage information from a plurality of automatic doors 100. The reception unit 202 supplies the received voltage information to the determination unit 204 and supplies a door identification command to the door identification unit 203, and the process S400 proceeds to step S406.

[0107] In step S406, the door identification unit 203 of the door management device 200 identifies a plurality of automatic doors 100 under approximate operating conditions where the operating conditions are similar. For example, among the above data constituting the operating conditions, for data that can be calculated (for example, climate-related numerical values such as temperature and humidity, the weight and dimensions of the automatic door, various setting values of the automatic door 100, the past operating rate and number of operating times of the automatic door 100), the difference value from the automatic door 100 to be determined for deterioration is calculated, and it can be determined that the automatic door 100 whose difference value is smaller than a predetermined threshold is under approximate operating conditions. At this time, if the priorities of each data are different in the determination of approximate operating conditions, the difference in priorities can be reflected by weighting the difference values of each data.

[0108] Also, among the above data constituting the operating conditions, for data that cannot be calculated (for example, data related to the geography and topography of the installation area of the automatic door, data related to the building where the automatic door is installed, the model number of the automatic door or its parts, the installation method of the automatic door), criteria for approximate determination without calculation can be set in advance. For example, for the model number, not only products with the same model number but also products with different model numbers belonging to the same product series can be regarded as approximate, and products belonging to different product series can be regarded as non-approximate.

[0109] The criteria for approximate determination as described above may be set in advance, or the user may set them each time according to needs.

[0110] By setting arbitrary criteria for approximate determination in this way, the door identification unit 203 can extract a plurality of automatic doors 100 under approximate operating conditions from a desired perspective. In this embodiment, when the door identification unit 203 identifies a plurality of automatic doors 100 from among a plurality of automatic doors 100, the automatic door to be determined for deterioration specified via the user input unit or the work terminal of the door management device 200 and one or more automatic doors under approximate operating conditions with it are identified. The door identification unit 203 supplies the identification result of the automatic door to the determination unit 204 of the door management device 200, and process S400 proceeds to step S407.

[0111] In step S407, the determination unit 204 of the door management device 200 determines the degree of deterioration of the AC power input capacitor 72A based on the voltage information of the identified automatic doors. For example, the determination unit 204 calculates a value serving as an index of the degree of deterioration of the AC power input capacitor 72A based on the degree of deviation of the minimum value of the average voltage of the AC power input capacitor 72A in the acceleration control operation in the voltage information of the automatic door 100 whose deterioration is to be determined with respect to the minimum value of the average voltage of the AC power input capacitor 72A in the acceleration control operation in the voltage information of the other identified automatic door 100, and uses this as the determination result. The determination unit 204 supplies the determination result of the degree of deterioration of the AC power input capacitor 72A to the output unit 106 of the door management device 200, and process S400 proceeds to step S408.

[0112] In step S408, the output unit 205 of the door management device 200 outputs the determination result of the degree of deterioration of the AC power input capacitor 72A. After step S408, process S400 ends.

[0113] As described above, in the fourth embodiment, the degree of deterioration of the capacitor 72 is determined based on the comparison of the voltage information of the identified multiple automatic doors 100. According to this configuration, voltage information is collected from multiple automatic doors 100, and the voltage information of the capacitors 72 of the automatic doors 100 under approximate operating conditions with similar operating conditions such as the installation location and usage status of the automatic doors 100 is compared to determine the degree of deterioration of the capacitors 72. By comparing the voltage information of the capacitors 72 of the automatic doors 100 under approximate operating conditions, when the capacitor 72 is deteriorated, the difference in voltage information clearly appears, so it becomes possible to more accurately determine the degree of deterioration of the capacitor 72.

Conversely, for those in which multiple functions are provided in an aggregated manner, some or all of the multiple functions may be provided in a dispersed manner.
