The dimensions of the parts in each drawing are enlarged or reduced as appropriate to facilitate understanding. Some parts that are not important for explaining the embodiments are omitted in each drawing.

[First embodiment]
Please refer to FIG. 1. The automatic door 100 mainly includes a door section 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 a person passing by, a drive unit 40 that generates power, and a power transmission unit 50 that transmits power to the door section 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 perpendicular 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 the installation direction is not limited to the following example. In the example of FIG. 1, an automatic door whose opening and closing method is a double-sliding type is shown, but this is not limited thereto, and the opening and closing method may be a single-sliding type, a swing door type, a folding door type, a rotating type, or the like. 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.

The door section 10 includes a first movable door 11L and a second movable door 11R that are each arranged to be movable in the horizontal direction, a first fixed door 12L and a second fixed door 12R that are arranged to overlap with the first movable door 11L and the second movable door 11R 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 section 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. When the door section 10 is driven to close, the first movable door 11L is driven to the right, and the second movable door 11R is driven to the left, which is the opposite of when the door section 10 is driven to open. The number and shape of the doors that make up the door section 10 are not limited to the above, and can be designed appropriately according to the needs of the installation location. Similarly, the movable direction of the door section 10 is not limited to the horizontal direction, but may be 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 in this embodiment is an example of a door.

The guide mechanism 13 includes a running rail 131, a door hanger 132, and a guide rail 133. The running rail 131 is a columnar rail member that extends horizontally above the first and second movable doors 11L, 11R over the entire range of their movement. The door hanger 132 attached to the upper part of the first and second movable doors 11L, 11R is suspended from the running 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 run on the running rail 131 while suspending each of the first and second movable doors 11L, 11R from the running rail 131. The guide rail 133 is a groove-shaped rail member that extends horizontally below the first and second movable doors 11L, 11R over the entire range of their movement. The guide rail 133 guides the first and second movable doors 11L and 11R in the opening and closing direction.

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 the set values of the travel speed, opening and closing strength, opening width, etc. The travel 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. In addition, the travel speed may be set to a different value during normal opening and closing and other times. For example, in the case of a so-called reversal in which the door section 10 is switched to an opening drive during normal closing drive to urgently avoid a passerby being pinched by the first and second movable doors 11L and 11R being closed, the speed of the first and second movable doors 11L and 11R during the opening drive may be set to a different value from the speed during normal opening drive.

The opening and closing strength is the magnitude of the force exerted when the first and second movable doors 11L, 11R are opened and closed, and is controlled by the torque value generated by the motor 41 of the drive unit 40 described below. As with the travel speed described above, it is preferable that the opening and closing strength of the first and second movable doors 11L, 11R is basically the same. Also, different opening and closing strengths may be set for normal opening and closing and other times. The opening width is the horizontal distance between the first movable door 11L and the second movable door 11R when the door unit 10 is fully open.

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 device implemented in a microcontroller, and is responsible for various information processing and control in the automatic door 100. The control device 21 controls the drive unit 40 to open and close the door unit 10 in response to the detection results of passersby and the like from the door sensor 30. The control device 21 can also 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 an operator's work terminal or a remote computer via the communication device 23.

The storage device 22 is a general-purpose memory that stores various data for the automatic door 100.

The communication device 23 exchanges various information with communication devices external to the automatic door 100 via wired or wireless connections. For example, the communication device 23 can communicate with a work terminal used by a worker who goes to the site to install or maintain the automatic door 100. This allows the worker to check information on each part of the automatic door 100 on the work terminal and input various data on the automatic door 100. If the communication device 23 has a communication function via a public information and communication network such as the Internet, it is possible to check information on the automatic door 100 and input data from a remote computer.

The door sensor 30 comprises 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 section 10. The activation sensor 31 comprises a light-emitting section that emits light such as infrared light toward the floor surface, and a light-receiving section that detects reflected light from the floor surface. When a person approaches the automatic door 100 and blocks the light, the amount of light received by the light-receiving section changes, making it possible to detect the person. When such detection information from the activation sensor 31 is input to the door controller 20, the motor 41 is driven to open the door section 10.

The auxiliary sensor 32 is a photoelectric sensor provided on the first fixed door 12L and the second fixed door 12R of the door section 10. The auxiliary sensor 32 has 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 section 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 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.

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 also be provided inside the door controller 20.

The drive unit 40 includes a motor 41 as a power source that generates rotational power, and a drive pulley 42 that is rotationally driven by the motor 41. The motor 41 can be configured as any of a variety of known motors, but in this embodiment, as an example, it is a brushless motor equipped with an encoder 41A that uses 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 drive voltage or drive current is applied to the motor 41 accordingly, thereby generating the desired rotational power. The drive 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 it.

The power transmission unit 50 transmits the power generated by the drive unit 40 to the door unit 10, and drives 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 a circular timing belt with many teeth formed on its inner circumferential surface, and is wound around the drive pulley 42 on the right side of FIG. 1, and 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 is rotated by the motor 41, the driven pulley 52 rotates in conjunction with it via the power transmission belt 51.

The connecting member 53 connects the first and second movable doors 11L, 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, which is an opening operation, and 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, which is a closing operation.

Figure 3 is a block diagram that shows the outline of the functions of the door controller 20 of this embodiment. Each functional block shown in each of the following figures is realized in hardware terms by a computer having calculation functions, control functions, memory functions, input functions, and output functions, various electronic elements, mechanical parts, etc., and in software terms by a computer program, etc., but here, functional blocks realized by the cooperation of these are depicted. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms by combining hardware and software.

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 judgment unit 105, an output unit 106, and a memory unit 107. The command acquisition unit 101 acquires an open command or a close command for the movable door 11 from, for example, a worker's work terminal. The position information acquisition unit 102 acquires a pulse signal from the encoder 41A as position information indicating the rotation position (door position) of the motor 41. The opening/closing control unit 103 controls the opening/closing of the movable door 11 by controlling 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. The voltage information acquisition unit 104 acquires voltage information indicating the output voltage of the AC power supply input capacitor 72A when at least one of the opening operation or closing operation of the movable door 11 is executed by the opening/closing control unit 103. The judgment unit 105 judges the degree of deterioration of the AC power supply input capacitor 72A based on the voltage information. The output unit 106 outputs the result of the judgment of the degree of deterioration of the AC power supply input capacitor 72A. The memory unit 107 stores various data such as voltage information, various thresholds, and operation information of the automatic door 100 (e.g., the driving voltage, driving current, energization time, and number of openings and closings of the motor 41).

In the door controller 20, the AC power supply 81 is connected to the converter circuit 71, and the AC power supply input capacitor 72A, which is a smoothing capacitor, is connected to the output of the converter circuit 71. The AC power supply input capacitor 72A smooths the waveform of the voltage output from the AC power supply 81 through the converter circuit 71 to form a DC power supply. The opening/closing control unit 103 PWM controls the inverter circuit 73 using the DC power supply. The output of the inverter circuit 73 is supplied to the motor 41, which rotates and drives the motor 41. 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 drives and controls the motor 41 based on this position information.

The output terminal of the AC power input capacitor 72A is connected to the primary terminal of the transformer 75 via the power supply control unit 74. The power supply control unit 74 controls the on/off of the current flowing through the transformer 75 so that the voltage supplied to the transformer 75 becomes a predetermined voltage based on the detection voltage of the voltage detection unit 77 (the relative voltage between the terminals of the voltage detection unit). A smoothing capacitor, or transformer output capacitor 72B, is connected to the secondary terminal of the transformer 75 via the power supply generation unit 76. The power supply 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 supply 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.

The processing of the door controller 20 of this embodiment will be described with reference to FIG. 4. FIG. 4 is a flowchart showing processing S100 of the door controller 20 of this embodiment. Below, an excerpt of the processing for timing acquisition of an open command from a state in which the movable door 11 is fully closed is shown as an example. Processing S100 is repeatedly executed at regular intervals (e.g., 10 milliseconds).

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

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

In step S103, the voltage information acquisition unit 104 acquires voltage information when the movable door 11 is driven to open. In this embodiment, the voltage information acquisition unit 104 acquires the output voltage of the AC power supply input capacitor 72A as voltage information when the movable door 11 is in an acceleration control operation to accelerate to the first speed.

Here, the relationship between the traveling speed of the movable door 11 and the voltage of the capacitor in the door controller 20 will be described with reference to FIG. 5 and FIG. 6. First, the opening operation of the movable door 11 of this embodiment will be described with reference to FIG. 5. The opening operation of the movable door 11 of this embodiment includes an acceleration control operation for accelerating the movable door 11 stopped at the closed position to a predetermined first speed V1, a high-speed control operation for maintaining the first speed V1, a deceleration control operation for decelerating to a second speed V2, a low-speed control operation for maintaining the second speed V2, and a door contact operation for stopping the movable door 11 by contacting it with a stopper (not shown). In the acceleration control operation, when the traveling speed reaches the first speed V1, the operation is switched to a 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 a deceleration control operation. In the deceleration control operation, when the traveling speed reaches the second speed V2, the operation is switched to a 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, the door hits the stopper and stops.

The average voltage of the capacitor during the opening operation will be described with reference to FIG. 5. In FIG. 5, average voltage E2 indicates the average voltage for a capacitor with little deterioration, and average voltage E3 indicates the average voltage for a capacitor with much deterioration. The average voltage here is, for example, the average value of the capacitor voltage 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 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 average voltage E3 is smaller than the minimum value of average voltage E2.

Figure 6 shows the change in capacitor voltage during a short time period R1 during acceleration control operation. Figure 6 shows the voltage during a time period R1 of 1.5 periods of the AC power supply voltage E6 of the AC power supply 81 during acceleration control operation. In Figure 6, voltage E1 shows the voltage when the automatic door 100 is not being driven, voltage E4 shows the voltage for a capacitor with little deterioration, and voltage E5 shows the voltage for a capacitor with much deterioration. E2 and E3 are as described above.

As shown by voltages E5 and E6, a large amount of power is suddenly required in the motor 41 during acceleration control operation, and the power stored in the capacitor is discharged to suppress the current change at this time, causing the capacitor voltage to drop. Here, if the capacity of the capacitor decreases due to its deterioration, the amount of stored power decreases, and the discharge cannot sufficiently suppress the sudden current change during acceleration control operation. As a result, the voltage E5 for a capacitor with a large degree of deterioration drops more than the voltage E4 for a capacitor with a small degree of deterioration. From the above, during 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 processing S100 proceeds to step S104.

In step S104, the determination unit 105 determines the degree of deterioration of the AC power input capacitor 72A based on the voltage information. In this embodiment, the memory unit 107 stores the voltage information acquired when the automatic door 100 is installed, and the determination unit 105 determines the degree of deterioration of the AC power input capacitor 72A based on the voltage information acquired when the automatic door 100 is installed. For example, the determination unit 105 calculates a value that is an index of the degree of deterioration of the AC power input capacitor 72A based on the degree of deviation (difference, ratio, etc.) between the minimum value of the average voltage of the AC power input capacitor 72A in the acceleration control operation in the voltage information acquired in step S103 and the minimum value of the average voltage of the AC power input capacitor 72A in the acceleration control operation in the voltage information acquired in step S103, and sets this as the determination result. The determination unit 105 supplies the determination result to the output unit 106.

In step S105, the output unit 106 outputs the judgment result. In this embodiment, the output unit 106 transmits the judgment result to, for example, the worker's work terminal via the communication device 23. As a result, the judgment result of the deterioration degree of the AC power supply input capacitor 72A is displayed on the display screen of the work terminal, etc., and can be used for the maintenance of the automatic door 100. For example, the worker can suggest the replacement of the door controller 20. After step S105, the process S100 ends.

The following describes the operation and effects of this embodiment.

A typical failure of the automatic door 100 is failure due to deterioration (drying up, etc.) of the AC power input capacitor 72A of the door controller 20. If deterioration of the AC power input capacitor 72A progresses, there are many cases where the door controller 20 will malfunction without warning and suddenly stop working.

In contrast, in this 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. This configuration makes it possible to appropriately determine the degree of deterioration of the AC power input capacitor 72A, thereby preventing the door controller 20 from suddenly failing and causing the automatic door 100 to become unusable.

In this embodiment, the voltage information acquisition unit 104 acquires the voltage of the AC power supply input capacitor 72A when the movable door 11 is in an acceleration control operation in which the movable door 11 accelerates to a first speed V1. With this configuration, the deterioration of the AC power supply input capacitor 72A during the acceleration control operation causes large fluctuations in the voltage of the AC power supply input capacitor 72A, making it possible to more accurately determine the degree of deterioration of the AC power supply input capacitor 72A.

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 when the automatic door 100 is installed. With this configuration, the degree of deterioration can be determined more accurately by using the voltage information obtained when the AC power input capacitor 72A is in a state where deterioration is extremely small when the automatic door 100 is installed as a reference.

In this embodiment, the output unit 106 outputs the result of the determination of the degree of deterioration of the AC power input capacitor 72A. With this configuration, it is possible to grasp the degree of deterioration of the AC power input capacitor 72A, making it possible to perform appropriate maintenance.

Below, we will explain some variations of this embodiment.

In the embodiment, the voltage information is acquired when the open drive is executed in response to the open command, but this is not limited to the above. For example, the voltage information may be acquired when the open drive is executed in response to the detection information of the activation sensor 31.

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 this is not limited to the above. 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. If the transformer output capacitor 72B deteriorates and malfunctions, the peripheral devices 82 such as the door sensor 30 will not function properly, and the automatic door 100 will not function properly. By determining the degree of deterioration of the transformer output capacitor 72B, it is possible to prevent the peripheral devices 82 from functioning properly and the automatic door 100 from functioning properly. Note that the voltage information of any capacitor may be used, not limited to the AC power input capacitor 72A and the transformer output capacitor 72B, as long as it is the voltage information of a capacitor provided in the door controller 20. Hereinafter, the capacitors provided in the door controller 20 may be collectively referred to as the capacitor 72.

In the embodiment, the voltage information is acquired when the open drive is performed, but this is not limited thereto, and the voltage information may be acquired when the close drive is performed.

In the embodiment, the voltage information during the acceleration control operation is acquired, but the present invention is not limited to this. The voltage information during the deceleration control operation (see FIG. 5) in which the movable door 11 is decelerated to the second speed V2, which is slower than the first speed V1, may be acquired. See FIG. 5 and FIG. 7. As shown in FIG. 5 and FIG. 7, in the deceleration control operation, the maximum value of the average voltage E3 is greater 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 proceeds and is supplied to the capacitor 72. Here, when the capacity of the capacitor 72 decreases due to its deterioration, the amount of stored electricity decreases. As a result, the voltage E5 for the capacitor with greater deterioration increases to a greater extent than the voltage E4 for the capacitor with less deterioration. From the above, in the deceleration control operation, the average voltage E3 is smaller than the average voltage E2. Therefore, it is possible to determine the degree of deterioration of the capacitor 72 by calculating the degree of deviation using the voltage information acquired in the deceleration control operation.

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 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 a security inspection of the automatic door 100.

In the embodiment, the voltage information when the movable door 11 is actually driven to open is acquired by driving the movable door 11 to open, but this is not limited to the above. For example, the voltage information may be acquired by reading from the memory unit 107 the voltage information when the movable door 11 was driven most recently, without driving the movable door 11. Also, in the above-mentioned door hitting operation, even when the movable door 11 is stopped in the fully closed position, control may be performed to continue driving and pressing the movable door 11 in the closing direction so that the movable door 11 does not open due to some factor. Even in this pressing control, the voltage of the AC power input capacitor 72A decreases, so the deterioration of the AC power input capacitor 72A may be determined using the voltage information during this pressing control.

Refer to FIG. 8. The automatic door 100 may be provided with an operation information acquisition unit 108 that acquires operation information of the automatic door 100. In this case, the judgment unit 105 may further judge the degree of deterioration of the capacitor based on the operation information. The operation information of the automatic door 100 here is, for example, the driving voltage, driving current, current flow time per drive, and number of opening and closing operations of the motor 41. If the AC power input capacitor 72A of the automatic door 100 is deteriorated, the automatic door 100 cannot be opened or closed as intended with a normal driving voltage or driving current, so the driving voltage or driving current becomes excessive or insufficient through a control loop, etc., and the deterioration of the AC power input capacitor 72A can be detected. Also, if the AC power input capacitor 72A of the automatic door 100 is deteriorated, the automatic door 100 cannot be opened or closed as intended, so the current flow time of the motor 41 per drive becomes longer than normal, and the deterioration of the AC power input capacitor 72A can be detected. In addition, the more the number of openings and closings, the greater the load on the AC power input capacitor 72A, making the AC power input capacitor 72A more susceptible to deterioration, so the deterioration of the AC power input capacitor 72A can also be detected by the number of openings and closings.

The operation information acquisition unit 108 may also acquire operation information of the peripheral device 82 connected to the automatic door 100 and receiving power from the automatic door 100. The operation information of the peripheral device 82 here is, for example, the number of times the peripheral device 82 has been operated, and if the peripheral device 82 is the door sensor 30 or one of the various sensors 33a to 33c of the detection device 33, the detection information is the detection strength of the sensor (the amount of light received in the case of a photoelectric sensor), the power supply time of the sensor per detection, etc. The more the peripheral device 82 is operated, the greater the load on the transformer output capacitor 72B becomes, and the more likely the transformer output capacitor 72B is to deteriorate, so that the deterioration of the transformer output capacitor 72B can be detected by the number of times it is operated. If 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, so the power supply time of the sensor per detection becomes longer than usual, and the deterioration of the transformer output capacitor 72B can be detected.

In summary, the operation information acquisition unit 108 may acquire operation information of at least one of the automatic door 100 and the peripheral device 82 connected to the automatic door 100 and receiving power from the automatic door 100. With this configuration, the degree of deterioration of the capacitor differs depending on the operating status of the automatic door 100 and the peripheral device 82, so the degree of deterioration can be determined more accurately based on the operation information.

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 further determine the degree of deterioration of the capacitor 72 based 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 memory unit 107 stores a score assigned to 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 a temperature of 0.9 to 1 atmosphere, and 11 points for a temperature of 1 to 1.1 atmosphere). For example, if the score assigned to the range corresponding to the average value of the environmental information from the time of construction of the automatic door 100 to the present exceeds a predetermined standard, the determination unit 105 may weight the voltage information by multiplying it by a predetermined constant greater than 1 so as to increase the absolute value of the voltage information. The capacitor 72 is also affected by the temperature, humidity, and air pressure around the automatic door 100. For example, the higher the temperature and humidity or the lower the air pressure in the environment around the automatic door 100, the greater the degree of deterioration of the capacitor 72. By further basing the determination on the environmental information, it becomes possible to accurately determine the degree of deterioration of the capacitor 72.

[Second embodiment]
A second embodiment of the present invention will be described below. In the drawings and description of the second embodiment, the same or equivalent components and members as those of the first embodiment are denoted by the same reference numerals. Explanations that overlap with the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the first embodiment.

In the first embodiment, the result of the deterioration degree determination was a value that was an index of the deterioration degree of the AC power input capacitor 72A, but is not limited to this. In the second embodiment, the result of the deterioration degree determination indicates whether or not the AC power input capacitor 72A has deteriorated.

The process of the door controller 20 of the second embodiment will be described with reference to FIG. 10. FIG. 10 is a flowchart showing the process S200 of the door controller 20 of the second embodiment. Steps S201 to S203 in process S200 are similar to steps S101 to S103 in process S100, and therefore will not be described.

After executing steps S201 to S203, in step S204, the judgment unit 105 judges whether or not the AC power supply input capacitor 72A has deteriorated based on the voltage information. For example, the judgment unit 105 judges whether or not the degree of deterioration judged based on the voltage information exceeds a predetermined reference value, and judges that the capacitor 72 has deteriorated if it exceeds the predetermined reference value. If the capacitor 72 has not deteriorated (N in step S204), the process S200 ends. If the capacitor 72 has deteriorated (Y in step S204), the judgment unit 105 supplies the judgment result indicating that the capacitor 72 has deteriorated to the opening/closing control unit 103, and the process S200 proceeds to step S205.

In step S205, the opening/closing control unit 103 changes the travel speed of the movable door 11 in the opening/closing control to a travel speed slower than the travel speed of the movable door 11 in the normal opening/closing control. By making the travel speed of the movable door 11 slower than normal, it is possible to make the fluctuation in the voltage applied to the AC power input capacitor 72A of the door controller 20 smaller than normal. This makes it possible to suppress deterioration of the AC power input capacitor 72A, and thereby suppress failure of the door controller 20. After step S205, the process S200 ends.

In the second embodiment, in step S205, the opening/closing control unit 103 changes the travel speed of the movable door 11 in the opening/closing control of the movable door 11 to a travel speed slower than the travel speed of the movable door 11 in normal opening/closing control, but this is not limited to the above. 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 normal opening/closing control.

If it is determined that the capacitor 72 is degraded, the output unit 106 may transmit the result of the degradation determination to the worker's work terminal, or may notify the worker that the capacitor 72 is degraded by flashing an LED (such as an LED used in the door sensor 30) mounted on the automatic door 100 in a specific pattern. The output unit 106 may also generate a buzzer sound from a sound source device (not shown) mounted on the automatic door 100.

[Third embodiment]
A third embodiment of the present invention will be described below. In the drawings and description of the third embodiment, the same or equivalent components and members as those of the first embodiment are denoted by the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from those of the first embodiment.

In the first embodiment, the degree of deterioration of the capacitor 72 is determined based on voltage information, but this is not limited to the above. 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.

Figure 11 is a block diagram that shows the outline of the functions of the door controller 20 of the second embodiment. The door controller 20 of the second embodiment includes a temperature transition information acquisition unit 110 instead of the voltage information acquisition unit 104 of the first embodiment.

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 this embodiment, temperature transition information related to the transformer output capacitor 72B is acquired. In this embodiment, the temperature sensor 83 measures the temperature of the transformer output capacitor 72B. The memory unit 107 stores the measurement 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 out the temperature of the transformer output capacitor 72B stored in the memory unit 107 in association with the measurement time. The judgment unit 105 judges the degree of deterioration of the transformer output capacitor 72B based on the temperature transition information.

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

The processing of the door controller 20 in 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 in the third embodiment.

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

In step S302, the temperature transition information acquisition unit 110 acquires temperature transition information indicating the transition of the temperature of the transformer output capacitor 72B over a predetermined period of time. This predetermined period can be, for example, the period from the 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 transition information acquisition unit 110 supplies the acquired temperature transition information to the determination unit 105, and processing S300 proceeds to step S303.

In step S303, the determination unit 105 determines the degree of deterioration of the transformer output capacitor 72B based on the temperature transition information. The specific determination process of step S303 will be described with reference to FIG. 14.

In step S311, the determination unit 105 calculates the average temperature for a specified time period (e.g., an hourly time period such as 1:00 to 2:00) for each day based on the temperature transition information. For example, in the example shown in Figures 15 and 16, the average temperature for each hour from 1:00 to 24:00 is calculated. Note that, for simplicity, Figures 15 and 16 show an example in which the specified period is one day, but in reality, the average temperature for each time period for the number of days corresponding to the specified period, such as one month, half a year, or one year, is calculated.

In step S312, the determination unit 105 assigns a temperature range to each time period on each day, based on the average temperature. As shown in FIG. 16, for example, the average temperature in the time period from 1:00 to 2:00 is 30°C, so a temperature range of 26 to 30°C is assigned. Also, for example, the average temperature in the time period from 10:00 to 11:00 is 41°C, so a temperature range of 41 to 45°C is assigned. This assigned temperature range is an example of the temperature of the capacitor 72 identified by the determination unit 105.

In step S313, the determination unit 105 determines the life consumption for each time period on each day based on the applied temperature range. For example, the determination unit 105 reads out the standard life consumption for each temperature range of the transformer output capacitor 72B from the memory unit 107, and determines the life consumption corresponding to the applied temperature range. In the example of FIG. 16, the determination unit 105 determines that the life consumption is 1/960,000 of the standard life time because the temperature range of 26 to 30°C is assigned to the time period from 1:00 to 2:00, and that the temperature range of 41 to 45°C is assigned to the time period from 10:00 to 11:00, so determines that the life consumption is 1/320,000 of the standard life time.

In step S314, the determination unit 105 calculates the cumulative value of the life consumption for the entire specified period by integrating the life consumption for each time period on each day. For example, in the example of Fig. 16, the hourly life consumption from 24:00 to 4:00 and 21:00 to 24:00 is 1/960000, the hourly life consumption from 4:00 to 7:00 and 18:00 to 21:00 is 1/640000, the hourly life consumption from 7:00 to 10:00 and 16:00 to 28:00 is 1/480000, and the hourly life consumption from 10:00 to 16:00 is 1/320000. Therefore, the cumulative value of life consumption in the example of Figure 16 is (1/960000 x 7) + (1/640000 x 6) + (1/480000 x 5) + (1/320000 x 6) = 11/240000. Therefore, in the example of Figure 16, the cumulative value of life consumption over the entire specified period is 11/240000 of the standard life time.

In step S315, the determination unit 105 determines the degree of deterioration of the transformer output capacitor 72B based on the cumulative value of the life consumption over the entire specified period. The determination unit 105 may generate a determination result in which the numerical value calculated as the cumulative value of the life consumption over the entire specified period is itself an index showing the degree of deterioration of the transformer output capacitor 72B, or may generate a determination result showing whether the transformer output capacitor 72B has deteriorated based on the result of comparing the numerical value calculated as the cumulative value with a threshold value. The determination unit 105 supplies the determination result of the degree of deterioration of the transformer output capacitor 72B to the output unit 106.

Returning to FIG. 13, in step S304, the output unit 106 outputs the result of the determination of the degree of deterioration of the transformer output capacitor 72B. Step S304 is basically the same as step S105, so its description is omitted. After step S304, the process S300 ends.

In this way, 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. With this configuration, the consumed life time of the transformer output capacitor 72B can be grasped based on the temperature transition, so that the degree of deterioration of the transformer output capacitor 72B can be accurately determined.

In addition, in the third embodiment, the determination unit calculates a cumulative value of the consumption of the lifetime of the capacitor 72 based on the temperature transition information and the standard lifetime consumption for each temperature of the capacitor 72, and determines the degree of deterioration of the capacitor 72 based on this cumulative value. With this configuration, the temperature transition of the capacitor 72 can be appropriately reflected in the degree of deterioration of the capacitor 72, so that the degree of deterioration of the transformer output capacitor 72B can be accurately determined.

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 this is not limited to the above. The degree of deterioration of another 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 only needs to detect the temperature of the capacitor 72 to be determined.

In the third embodiment, the average temperature of the capacitor 72 is calculated for each time period, but this is not limiting. For example, the average temperature of the capacitor 72 over the entire specified period may be calculated, and the lifetime consumption may be calculated based on this average temperature. In the third embodiment, the determination unit 105 identifies the applied temperature range as the temperature of the capacitor 72, but this is not limiting. For example, the determination unit 105 may identify the average temperature of the capacitor 72 over the entire specified period as the temperature of the capacitor 72.

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 openings and closings or the number of operations exceeds a predetermined number, the determination unit 105 weights the life consumption by multiplying it by a predetermined coefficient so as to increase the life consumption, and determines the degree of deterioration of the capacitor using the weighted life consumption.

Similarly, in the third embodiment, the environmental information acquisition unit 109 shown in FIG. 9 may be provided. In this case, for example, when the score obtained based on the environmental information exceeds a predetermined standard, the determination unit 105 weights the lifetime consumption by multiplying it by a predetermined coefficient so as to increase the lifetime consumption, and uses the weighted lifetime consumption to determine the degree of deterioration of the capacitor.

The memory unit 107 may store a trained model for determining the degree of deterioration of the capacitor 72. In this case, the determination unit 105 may use this trained model to determine the degree of deterioration of the capacitor 72. This trained model is an AI model generated by machine learning based on actual measurement 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, actual measurement data of the degree of deterioration of the capacitor 72 obtained from the actual measurement value of the capacitance of the capacitor 72). This trained model can be generated using a known machine learning method such as a support vector machine, a neural network (including deep learning), or a random forest. Based on the input data, this trained model outputs the degree of deterioration of the capacitor 72 corresponding to the input data as output data. For example, this trained model includes at least one of voltage information and temperature transition information as input data, and further includes at least one of standard life time, standard life consumption, temperature, humidity, air pressure, drive voltage and drive current of motor 41, current flow time and number of openings and closings per drive, number of operations of peripheral device 82, and, if peripheral device 82 is door sensor 30 or the like, the detection strength of the sensor and current flow time per detection as input data. Using a trained model is advantageous for speeding up data processing and achieving high determination accuracy.

[Fourth embodiment]
A fourth embodiment of the present invention will be described below. In the drawings and description of the fourth embodiment, the same or equivalent components and members as those of the first embodiment are denoted by the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from those of the first embodiment.

The door management system 1 will be described with reference to FIG. 17. FIG. 17 is a functional block diagram of the door controller 20 and door management device 200 of the automatic door 100 of this embodiment. The door management system 1 includes the door management device 200 and multiple automatic doors 100. The door management device 200 is connected to the multiple 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 command to each automatic door 100 to obtain voltage information. The door controller 20 of each automatic door 100 can transmit voltage information, etc. to the door management device 200.

The door controller 20 includes a command acquisition unit 101, a voltage information acquisition unit 104, an output unit 106, and a memory 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 operating condition memory 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 multiple automatic doors 100.

The operating conditions storage unit 206 records the operating conditions of the multiple automatic doors 100A to 100N in a unified manner. While the above-mentioned "operating information" is information related to the actual operation of the door controller 20 of the automatic door 100, the "operating conditions" are information related to the prerequisites for operating the automatic door 100. The data that constitutes the operating conditions is broadly divided into the following four types.
(1) Installation environment data (2) Unique data (3) Configuration data (4) Operation history data

The installation environment data includes data on the area where the automatic door 100 is installed, data on the building or facility where the automatic door 100 is installed, and other data on the installation environment of the automatic door 100. Examples of data on the installation area include meteorological data on the weather, climate, and climate of the area, such as temperature, humidity, temperature difference between day and night, wind speed, wind direction, precipitation, and sunshine, as well as data on the damage history and risk of natural disasters such as typhoons and earthquakes, and data on geography and topography, such as proximity to the sea or mountains. Examples of data on the building or facility where the automatic door 100 is installed include the construction method and structure of the building, the number of floors on which the automatic door is installed, the floor plan of the floor on which the automatic door is installed, the materials of the floor, wall, and ceiling surfaces where the automatic door is installed, the air conditioning and sunlight conditions of the automatic door installation location, and the type of facility (hospital, school, etc.).

The unique data includes data on the model number and specifications of the automatic door 100 or its parts, data on the timing and method of installation of the automatic door, etc. The specifications of the automatic door 100 include a variety of data, but the weight, dimensions, shape, and material of the door are particularly important. The timing of installation of the automatic door 100 can record not only the date of initial installation, but also the date of replacement or repair. Data on the installation method of the automatic door 100 can record the installation direction of the automatic door 100, and the mounting height from the floor of the activation sensor 31 and auxiliary sensor 32, etc.

The setting data includes setting values related to the opening and closing drive of the automatic door 100, setting values related to the detection of passers-by by the automatic door 100, etc. Examples of setting 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, an example of a setting value related to the detection of passers-by by the automatic door is the detection sensitivity of the activation sensor 31 and auxiliary sensor 32. Here, the detection sensitivity is set as a threshold value for the amount of received light that determines that a passer-by has been detected. When the threshold value is small, the detection sensitivity is high, and even a small amount of received light is determined to have been detected. Conversely, when the threshold value is large, the detection sensitivity is low, and even a small amount of received light is not determined to have been detected.

The operation history data includes 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 period of time in the past. It is also preferable to distinguish and record the number of normal opening and closing operations from the number of times the door has been reversed to open operation during the closing operation. This is because a reversal operation places a greater burden on the automatic door 100 than a normal opening and closing operation, and an automatic door that has a large number of reversals needs to be given priority in maintenance and inspection. The past operation rate can be recorded, for example, as the number of opening and closing operations per day.

The operating conditions of each automatic door 100 as described above are recorded, for example, as follows. Since much of the "installation environment data" and "unique data" does not change after the automatic door 100 is installed, these data are recorded together in the operating condition storage unit 206 of the door management device 200 when the automatic door 100 is installed. The recording work may be performed manually, for example, via an operator's work terminal, or, depending on the item, may be automatically entered without human intervention. Data that changes after installation, such as weather data included in the installation environment data, and data on damage history and risks of natural disasters, is updated as needed. Since these data are not directly related to the automatic door, they can be easily obtained via the Internet, etc. Furthermore, if the unique data changes due to parts replacement or adjustments to the installation method, it can also be updated as appropriate.

The "setting data" is the initial setting data recorded by workers when the automatic doors are installed. If the setting data is changed after installation, the operating conditions are updated based on the changed setting data. The "operating history data" is provided to the door management device 200 via the output unit 106 of each automatic door 100 and is recorded in the operating conditions memory unit 206.

The door identification unit 203 identifies multiple automatic doors 100 that are in similar 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 to be subjected to deterioration judgment, which is specified via a user input unit (not shown) of the door management device 200 or a work terminal, etc., and other automatic doors 100 that are in similar operating conditions.

Figure 18 is a sequence diagram of processing S400 by the door controller 20 and door management device 200 of this embodiment.

In step S401, the command transmission unit 201 of the door management device 200 transmits a command to acquire voltage information to each door controller 20. In this embodiment, for example, the command transmission unit 201 of the door management device 200 transmits the acquisition command to each door controller 20 in response to receiving a user input from an operator via a user input unit (not shown) of the door management device 200 specifying the automatic door 100 to be subjected to deterioration judgment.

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.

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

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

In step S405, the receiving unit 202 of the door management device 200 receives voltage information from the multiple automatic doors 100. The receiving unit 202 supplies the received voltage information to the determination unit 204 and also supplies a door identification command to the door identification unit 203, and processing S400 proceeds to step S406.

In step S406, the door identification unit 203 of the door management device 200 identifies multiple automatic doors 100 that are in approximate operating conditions. For example, for the above data constituting the operating conditions that can be calculated (e.g., climate-related values such as temperature and humidity, the weight and dimensions of the automatic door, various settings of the automatic door 100, and the past operating rate and number of times the automatic door 100 has been operated), the difference value with the automatic door 100 that is the subject of deterioration judgment is calculated, and an automatic door 100 whose difference value is smaller than a predetermined threshold value can be judged to be in approximate operating conditions. At this time, if the priority of each data differs in the judgment of the approximate operating conditions, the difference in priority can be reflected by weighting the difference value of each data.

Furthermore, for data that cannot be calculated from among the above data constituting the operating conditions (for example, data related to the geography and topography of the area in which the automatic doors are installed, data related to the building in which the automatic doors are installed, model numbers of the automatic doors or their parts, and installation methods), criteria for determining similarity without calculation can be set in advance. For example, with regard to model numbers, not only products with the same model number but also products with different model numbers that belong to the same product series can be considered similar, and products that belong to different product series can be considered non-approximate.

The criteria for determining similarity as described above may be set in advance, or may be set by the user on an ad-hoc basis according to needs.

By setting arbitrary criteria for the approximate judgment in this manner, the door identification unit 203 can extract multiple automatic doors 100 that are in approximate operating conditions from the desired viewpoint. In this embodiment, when the door identification unit 203 identifies multiple automatic doors 100 from among multiple automatic doors 100, it identifies the automatic door to be judged for deterioration, which is specified via the user input unit or work terminal of the door management device 200, and one or more automatic doors that are in approximate operating conditions to the automatic door. The door identification unit 203 supplies the automatic door identification result to the judgment unit 204 of the door management device 200, and processing S400 proceeds to step S407.

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 between the identified automatic doors. For example, the determination unit 204 calculates a value that is an index of the deterioration degree of the AC power input capacitor 72A based on the degree of deviation between 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 to be subjected to deterioration determination from 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 identified other automatic doors 100, and sets this as the determination result. The determination unit 204 supplies the determination result of the deterioration degree of the AC power input capacitor 72A to the output unit 106 of the door management device 200, and the process S400 proceeds to step S408.

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

As described above, in the fourth embodiment, the degree of deterioration of the capacitor 72 is determined based on a 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 capacitor 72 of automatic doors 100 that are in similar operating conditions, such as the installation location and usage conditions of the automatic doors 100, is compared to determine the degree of deterioration of the capacitor 72. By comparing the voltage information of the capacitor 72 of automatic doors 100 that are in similar operating conditions, the difference in voltage information becomes clear if the capacitor 72 is deteriorated, making it possible to more accurately determine the degree of deterioration of the capacitor 72.

Among the embodiments disclosed in this specification, those in which multiple functions are provided in a distributed manner may have some or all of the multiple functions consolidated, and conversely, those in which multiple functions are provided in a consolidated manner may have some or all of the multiple functions distributed. Regardless of whether the functions are consolidated or distributed, it is sufficient that the configuration is such that the object of the invention can be achieved.
