Summary of the Invention

Problems to be Solved by the Invention

[0004] A non-contact switch enables the opening and closing of a door by a non-contact operation of a user using a non-contact sensor, and the need for it as an opening / closing switch for an automatic door is increasing due to hygienic requirements. However, a non-contact switch is more likely to cause malfunction due to the influence of electromagnetic noise or the like than a physical switch such as a push button switch, and depending on its sensitivity, the automatic door may open unnecessarily when a person or an object inadvertently enters the detection area of the sensor. Patent Document 1 does not provide sufficient disclosure from the viewpoint of optimizing the sensitivity of the non-contact switch.

[0005] This invention has been made in view of these problems, and one of its objectives is to provide a technology for an automatic door system that can optimize the sensitivity of a non-contact switch. [Means for solving the problem]

[0006] To solve the above problems, an automatic door device according to one aspect of the present invention comprises a door provided in the opening of a private room and controlled to open and close, a non-contact open switch provided outside the private room for opening the door, an entry detection unit for detecting whether or not someone has entered the private room, and a storage unit for storing the number of times the open switch has been turned on and the number of times the entry detection unit has detected an entry.

[0007] Furthermore, any combination of the above, or any substitution of the components or expressions of the present invention between methods, apparatus, programs, temporary or non-temporary storage media recording programs, systems, etc., are also valid embodiments of the present invention. [Effects of the Invention]

[0010] Among the embodiments disclosed herein, those composed of multiple objects may be integrated, and conversely, those composed of a single object may be divided into multiple objects. Whether or not they are integrated, the invention can be constructed in a way that achieves its objective.

[0011] In the embodiments disclosed herein, those in which multiple functions are provided in a distributed manner may have some or all of those multiple functions integrated into a single unit, and conversely, those in which multiple functions are integrated may have some or all of those functions provided in a distributed manner. Whether the functions are integrated or distributed, the configuration should be such that the objective of the invention can be achieved.

[0012] Furthermore, separate components that share common characteristics are distinguished by adding "1st," "2nd," etc., to the beginning of their names, and these are omitted when referring to them collectively. In addition, terms containing ordinal numbers such as "1st," "2nd," etc., are used to describe various components, but these terms are used solely for the purpose of distinguishing one component from others, and do not limit the components themselves.

[0013] Hereinafter, the present invention will be described with reference to the drawings based on preferred embodiments. In the embodiments and modifications, the same or equivalent components and members are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate. Also, the dimensions of the members in each drawing are shown enlarged or reduced as appropriate for easy understanding. Further, some of the members that are not important for describing the embodiments in each drawing are omitted from the display.

[0014] [First Embodiment] Hereinafter, the automatic door device 100 according to the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing the configuration of the private room 1 in which the automatic door device 100 of the present embodiment is installed. The private room 1 in this example is a private room having one opening 2 that functions as an entrance and exit, and is a multi-functional toilet in which a toilet 18 is installed in a large space so that it is easy for a person with a disability or a person with children to use. As shown in FIG. 1, an automatic door device 100 that drives and controls a door 4 for opening and closing the opening 2 is installed in the opening 2. The door 4 can use various known doors, and in this example, it is a sliding door.

[0015] In this specification, the operation of opening the door 4 and the operation of closing it are referred to as "opening operation" and "closing operation", respectively, and when these are summarized, they are referred to as "opening and closing operation". Also, the control for causing the opening operation and the control for causing the closing operation are referred to as "opening control" and "closing control", respectively, and when these are summarized, they are referred to as "opening and closing control".

[0016] An auxiliary sensor 13 is installed on the inner wall of the opening 2 to detect objects such as people passing through the opening 2. For example, the auxiliary sensor 13 may include a photoelectric sensor capable of detecting objects according to the blocking state of the light beam 13b. The auxiliary sensor 13 provides the information processing unit 16 with a detection signal indicating whether or not an object is being detected in the opening 2 using the photoelectric sensor. An occupancy sensor 15 is installed on the ceiling inside the private room 1 to detect the user inside the private room. For example, the occupancy sensor 15 is configured to include a pyroelectric element capable of detecting changes in infrared radiation emitted by a person and functions as a human presence sensor. The occupancy sensor 15 provides the information processing unit 16 with a detection signal indicating whether or not a person is being detected according to the signal from the pyroelectric element.

[0017] The automatic door device 100 includes a door 4 installed in the opening 2 of the private room 1 and controlled for opening and closing, an outer door operating device 30 installed outside the private room 1 for opening and closing the door 4, and an inner door operating device 40 installed inside the private room 1 for opening and closing the door 4. The outer door operating device 30 and the inner door operating device 40 are collectively referred to simply as the door operating device. The outer door operating device 30 is installed on the outer (outside) wall of the private room 1, and the user can open and close the door 4 using the outer door operating device 30. The inner door operating device 40 is installed on the inner (inside) wall of the private room 1, and the user can open and close the door 4 using the inner door operating device 40.

[0018] Figure 2 shows the door operating device of the automatic door system 100. Figure 3 is a cross-sectional view showing the door operating device of the automatic door system 100. Figure 2(A) shows the outer door operating device 30, Figure 2(B) shows the inner door operating device 40, and Figure 3 shows a cross-section of the outer door operating device 30 along line AA. The inner door operating device 40 has the same cross-section as the outer door operating device 30. The outer door operating device 30 and the inner door operating device 40 of this embodiment are equipped with switches for opening and closing the door 4. As an example, the outer door operating device 30 and the inner door operating device 40 have the same configuration.

[0019] The exterior door operating device 30 includes a non-contact open switch 31, a non-contact close switch 32, a contact open switch 33, and a contact close switch 34. The interior door operating device 40 includes a non-contact open switch 41, a non-contact close switch 42, a contact open switch 43, and a contact close switch 44. The open switches 31, 32, 33, and 34 may be labeled with "inside" and "outside" to indicate the inside and outside of the individual room, respectively, or they may be labeled without "open" and "closed".

[0020] When referring to the non-contact open switch 31, close switch 32, open switch 41, and close switch 42 collectively, they are referred to as non-contact switches. The non-contact switches detect the user based on non-contact operation that does not involve physical contact with the user and provide an open / close instruction signal to the information processing unit 16 to open or close the door 4.

[0021] When referring to the contact-type open switch 33, close switch 34, open switch 43, and close switch 44 collectively, they are referred to as contact-type switches. Contact-type switches provide the information processing unit 16 with an open / close instruction signal to open or close the door 4 based on a contact operation by the user pressing a button switch. Non-contact-type switches are built into the outer door operating device 30 and the inner door operating device 40. The outer door operating device 30 and the inner door operating device 40 are examples of switches 3 for automatic door devices, which will be described later. When referring to non-contact-type switches and contact-type switches collectively, they are sometimes called "open / close switch group" or "switch group."

[0022] As shown in Figure 2, the open switches 31, 33, 41, and 43 are installed above the closed switches 32, 34, 42, and 44. The surface of the open switches 33 and 43 is marked "Open". The surface of the closed switches 34 and 44 is marked "Close". When the open switches 31 and 33 are grouped together, they are called the outer open switch 35. When the closed switches 32 and 34 are grouped together, they are called the outer closed switch 36. When the outer open switch 35 and the outer closed switch 36 are grouped together, they are called the outer on / off switch 37. When the open switches 41 and 43 are grouped together, they are called the inner open switch 45. When the closed switches 42 and 44 are grouped together, they are called the inner closed switch 46. When the inner open switch 45 and the inner closed switch 46 are grouped together, they are called the inner on / off switch 47.

[0023] As a non-contact switch, a non-contact sensor based on a known principle can be used, and the detection method is not limited. The non-contact switch in this embodiment uses a capacitive non-contact sensor that detects user operation using changes in capacitance. The non-contact switch in this example has an electrode part whose capacitance changes depending on the proximity of the user, that is, according to the distance from the user, and when the amount of change in the capacitance of the electrode part from a reference value remains above a threshold for a predetermined period of time, a signal indicating that user operation has been detected is provided to the information processing unit 16.

[0024] In this embodiment, as shown in Figure 3, the non-contact switch has a detection area R on the front side of the non-contact switch for detecting a user. When an object enters the detection area R, it enters a detection state, and when the object leaves the detection area R, it enters a non-detection state. Hereinafter, for both non-contact and contact switches, the switch is referred to as "on" when it is in a detection state, and "off" when it is in a non-detection state. Furthermore, the sensitivity of the non-contact switch can be changed by changing the detection area R. Specifically, increasing the sensitivity widens the detection area R, and decreasing the sensitivity narrows the detection area R.

[0025] As another example, a non-contact switch may be a reflected wave type that detects user operation based on the reflected waves after irradiating it with electromagnetic waves such as millimeter waves. As yet another example, a non-contact switch may be configured by combining multiple detection methods. For example, a capacitive method may be combined with a reflected wave method.

[0026] As a contact-type switch, a contact-type sensor based on a known principle can be used, and the detection method is not limited. The contact-type switch in this embodiment uses a button switch that opens and closes electrical contacts according to the amount the button is pressed. When the electrical contacts of the contact-type switch are opened, it provides a signal to the information processing unit 16 indicating that an operation has been detected.

[0027] In this embodiment, the non-contact switches are arranged to turn on when the contact switches are operated. Specifically, as shown in Figure 3, the non-contact switches are arranged in a layered manner on top of the contact switches. The non-contact switches include an operation detection area R for detecting non-contact operation, and the operation detection area R includes the installation location of the contact switches. Since the push button B of the contact switches is located within the detection area R of the non-contact switches, when a user operates the push button B with their hand, their hand enters the detection area R, and the non-contact switches turn on. For example, when a user presses the open switch 33, the operation detection area R is configured such that the user's hand enters the operation detection area R of the open switch 31.

[0028] Figure 4 is a block diagram showing the functional blocks of an automatic door system. Each functional block shown in Figure 4 can be implemented hardware-wise using components such as a computer processor, CPU, and memory, as well as electronic circuits and mechanical devices, and software-wise using computer programs, etc. However, this diagram depicts the functional blocks that are realized through the coordination of these components. Therefore, it will be understood by those skilled in the art that these functional blocks can be implemented in various ways through combinations of hardware and software.

[0029] The automatic door system 100 includes a door engine 14 for driving the door 4, an auxiliary sensor 13, an occupancy sensor 15, an outer door operating device 30, an inner door operating device 40, an extension operating unit 19, and an information processing unit 16 to which these devices are connected. The auxiliary sensor 13, the occupancy sensor 15, the outer door operating device 30, the inner door operating device 40, and the extension operating unit 19 are connected to the information processing unit 16 via an information transmission means 50 based on known principles. The information transmission means 50 may include CAN, which is a type of intra-area network.

[0030] The information processing unit 16 functions as a door controller that controls the opening and closing operation of the door 4. The information processing unit 16 includes, as functional blocks, an input unit 16a, an entry detection unit 5, a storage unit 6, a judgment unit 7, an adjustment unit 8, a fault diagnosis unit 9, a notification unit 10, a specific closing control unit 11, a long-term use management unit 12, a door control unit 16d, and a communication unit 16e. These functional blocks can communicate information with each other via a data bus 16b. Some of the functional blocks of the information processing unit 16 may be provided separately from the door controller, or they may be provided in external equipment or external systems of the automatic door device 100.

[0031] The input unit 16a receives signals from the auxiliary sensor 13, the occupancy sensor 15, the outer door operating device 30, the inner door operating device 40, and the extension operating unit 19 via the information transmission means 50. The communication unit 16e transmits predetermined information to the outside.

[0032] The entry detection unit 5 detects whether or not someone has entered the private room 1. The entry detection unit 5 can be configured to include one or more detection means capable of detecting whether or not a person or object has entered the private room 1. In this embodiment, the entry detection unit 5 includes an auxiliary sensor 13 and an occupancy sensor 15 as detection means, and determines that there has been an entry if either the auxiliary sensor 13 or the occupancy sensor 15 detects the entry of a person or object into the private room 1.

[0033] The specific closing control unit 11 will now be explained. Door 4 may remain open for an extended period due to the user forgetting to close it when leaving private room 1 or due to a malfunction of the outside open switch 31. In this case, it is desirable for the automatic door device 100 to automatically control the closing of door 4. Therefore, the automatic door device 100 of this embodiment is equipped with a specific closing control unit 11 to prevent the door 4 from being forgotten to be closed.

[0034] The specific closing control unit 11 determines that the door has been "forgotten to close" if the door 4 is opened based on the signal from the outside open switch 31 but is not closed after a predetermined period of time has elapsed, and controls the door 4 to open regardless of user operation. The specific closing control unit 11 functions as a door-forgetting prevention device.

[0035] Specifically, the specific closing control unit 11 closes the door 4 after the door control unit 16d has opened the door 4 based on the signal from the outer open switch 31, regardless of the signals from the inner close switch 42 and the outer close switch 32 (hereinafter referred to as "specific closing control"). The predetermined period for specific closing control can be set by experiment or simulation from the viewpoint of convenience of using the private room 1, and may be, for example, 20 to 120 seconds.

[0036] The specific closing control unit 11 performs specific closing control even when the auxiliary sensor 13 or the occupancy sensor 15 is turned on in a detection state.

[0037] The storage unit 6 functions as a memory for storing various information and control programs P100, P200, P300, and P400. The storage unit 6 also stores the number of times the open switch 31, close switch 32, open switch 33, close switch 34, open switch 41, close switch 42, open switch 43 and close switch 44, and the extension operation unit 19 are turned on. The storage unit 6 also stores the number of detections by the entry detection unit 5. The storage unit 6 also stores the number of times a specific closing control has been executed (hereinafter referred to as the "number of specific closing controls"). The storage unit 6 may also store the judgment result of the judgment unit 7.

[0038] In Figure 4, the memory unit 6 may be provided in the information processing unit 16, in the door operating device, in an external device of the automatic door device 100, or in an external system of the private room 1 via a communication means.

[0039] The determination unit 7 determines that unnecessary opening and closing of the door 4 has occurred when the predetermined conditions described later are met. The determination unit 7 also determines that the object being judged is malfunctioning when the predetermined conditions described later are met. The determination unit 7 may be provided in the information processing unit 16, in the door operating device, in an external device of the automatic door device 100, or in an external system.

[0040] The adjustment unit 8 changes the sensitivity of the non-contact switches 31, 32, 41, and 42 when predetermined conditions described later are met, adjusting the sensitivity to increase or decrease. The adjustment unit 8 may be provided in the information processing unit 16, in the door operating device, in an external device of the automatic door device 100, or in an external system.

[0041] The fault diagnosis unit 9 determines that the object under evaluation is faulty when it meets the predetermined conditions described later. The fault diagnosis unit 9 may be provided in the information processing unit 16, in an external device of the automatic door device 100, or in an external system.

[0042] The notification unit 10 notifies in either the case when the fault diagnosis unit 9 determines that there is a fault, or when the judgment unit 7 determines that unnecessary opening and closing has occurred, or both. For example, the notification unit 10 transmits a control signal to the notification unit 60 to activate the notification unit 60, which outputs warnings that can be perceived by humans, such as light, sound, and vibration. For example, the notification unit 10 may transmit notification information to a work terminal 70 carried by an operator via the communication unit 16e, or it may display the notification information on the display of the work terminal 70. The notification unit 10 may be provided integrally with the door operating device, or it may be provided in an external device or external system of the automatic door device 100.

[0043] The notification unit 60 in this embodiment includes a light-emitting device such as an LED, which lights up to indicate that a contactless operation has been detected. The notification unit 60 may include a speaker that generates a buzzer sound or the like, or it may include both a light-emitting device and a speaker. The notification unit 60 may be provided on the outer door operating device 30 and the inner door operating device 40, respectively, on the surrounding wall of the private room 1, or at any other location.

[0044] The door control unit 16d transmits control signals to the door engine 14 to drive the door 4 to open and close, based on signals from the auxiliary sensor 13, the occupancy sensor 15, the outer door operating device 30, and the inner door operating device 40, and drives the door engine 14. The door control unit 16d may also control the opening and closing of the door 4 based on signals from the inner open switch 41, the inner close switch 42, the outer open switch 31, and the outer close switch 32.

[0045] Figure 5 is a block diagram showing the external work terminal 70 of the automatic door device 100. The automatic door device 100 is configured to communicate with the external work terminal 70 via a communication unit 57. In Figure 5, an example is shown in which the communication unit 57 is provided in the outer door operating device 30 and the inner door operating device 40, but it is not limited to this and may be provided in other components such as the information processing unit 16.

[0046] The work terminal 70 is a smartphone or tablet used by workers who go to the site to install or maintain the automatic door device 100. The work terminal 70 is configured to send user input to the automatic door device 100 to change the sensitivity of the contactless switch by launching a dedicated application for the contactless switch.

[0047] The communication unit 57 is configured to communicate with the work terminal 70. The transmission path for communication between the communication unit 57 and the work terminal 70 may be a wireless communication transmission path, a wired communication transmission path, or a combination of a wireless communication transmission path and a wired communication transmission path. The communication unit 57 receives various user inputs from the work terminal 70.

[0048] Since the non-contact switches 31, 32, 41, and 42 operate similarly, the operation of the open switch 31 will be explained as a representative example. Figure 6 is a schematic diagram showing the operation of the non-contact open switch 31. In Figure 6, the horizontal axis represents elapsed time, and graph g1 shows the capacitance of the open switch 31. Graph g2 is the output signal of the open switch 31.

[0049] In the first state, when the object to be detected, such as the user's hand, is sufficiently far from the switch, the capacitance g1 of the open switch 31 is at the reference value S0. In the second state, when the object to be detected approaches the switch, the capacitance g1 becomes greater than the reference value S0, and the capacitance g1 is at its maximum when the object to be detected is closest. As the object to be detected moves away from the switch, the capacitance g1 gradually decreases, and in the third state, when it is sufficiently far away, the capacitance g1 returns to the reference value S0.

[0050] In Figure 6, graph g2 represents the output signal of the open switch 31. When the capacitance g1 is less than the threshold Th, the open switch 31 is off, and the output signal g2 is low level. When the capacitance g1 is greater than or equal to the threshold Th, the open switch 31 is on, and the output signal g2 is high level.

[0051] The memory unit 6 stores the history of the reference value S0 and threshold Th of each of the non-contact switches 31, 32, 41, and 42 in chronological order, and the work terminal 70 can retrieve and display the history of the reference value S0 and threshold Th of the non-contact switches 31, 32, 41, and 42 from the memory unit 6.

[0052] The work terminal 70 can adjust the sensitivity of switches 31, 32, 41, and 42. For example, this sensitivity adjustment can be performed by changing either the reference value or the threshold value, or both, of switches 31, 32, 41, and 42. The sensitivity can be decreased by increasing the difference between the reference value and the threshold value, and the sensitivity can be increased by decreasing the difference between the reference value and the threshold value. The adjustment unit 8 automatically adjusts the sensitivity of switches 31, 32, 41, and 42 in predetermined cases, regardless of operation of the work terminal 70.

[0053] The maintenance information screen of the work terminal 70 will be explained with reference to Figures 7 and 8. Figures 7 and 8 are schematic diagrams illustrating the maintenance information screen of the work terminal 70. In this embodiment, the maintenance worker can check the following information on the work terminal 70 using the maintenance information screen shown in Figure 7. (1) Unnecessary number of on / off cycles due to non-contact switches (2) Number of times open and closed by contact switch (3) Number of open and close controls using a non-contact switch (4) Number of calibrations performed (excluding calibration after power-on) (5) Average value of the reference value of capacitance Maintenance managers can refer to these values ​​to check the operational status of contactless switches and the real-time detection status.

[0054] Calibration is triggered by changes in capacitance values ​​due to rapid changes in the surrounding environment, or by noise. These surrounding environment factors include temperature, humidity, and the continuous approach of objects to be detected.

[0055] Furthermore, the maintenance worker can check the following information on the reference screen of the work terminal 70 shown in Figure 8. (6) Current capacitance reference value (The value can be viewed in real time as a bar graph) (7) Change from the current capacitance reference value (the value can be viewed in real time) Maintenance personnel can check the operating status of the contactless switch and the real-time detection status by referring to the information on the screens shown in Figures 7 and 8 of the work terminal 70.

[0056] For example, in situations where calibration is performed an extremely large number of times, we can recommend adding noise suppression components. Also, if the average value of the capacitance reference value in Figure 7 is significantly different from the current capacitance reference value of the switch in Figure 8, or if the displayed values ​​of the non-contact open switch and closed switch in Figure 8 differ significantly, we can infer that there is a malfunction in the non-contact function and recommend replacement.

[0057] Furthermore, if the number of times the switch is opened and closed by the contact switch is greater than the number of times it is opened and closed by the non-contact switch, as shown in the information in Figure 7, it may indicate that the non-contact sensor is not functioning, or that there was a period in the past when this function was not working. By accumulating data for both the internal and external opening and closing switches, it is possible to identify switches that may be malfunctioning.

[0058] Furthermore, the display information in Figure 8 allows for real-time confirmation of the detection status, including the current capacitance reference value and the change in the current capacitance, making it possible to determine whether the non-contact sensor is functioning correctly. Additionally, the display information in Figure 8 allows for confirmation of the detection area.

[0059] Furthermore, by checking the number of unnecessary openings and closings by the non-contact switch shown in Figure 7, it is possible to determine the number of times the door was opened by the non-contact switch but the individual room was not used. As a result, it is possible to determine the number of times the door may have been opened or closed due to a malfunction of the non-contact switch.

[0060] It is desirable to manage the prolonged use of individual stall 1, which is a multi-functional toilet, to prompt those who use individual stall 1 for an extended period of time for purposes other than its intended use to leave, or to facilitate early detection if a person using individual stall 1 for its intended use becomes ill. Therefore, the automatic door device 100 of this embodiment is equipped with a prolonged use management unit 12 for managing the prolonged use of individual stall 1. As an example, the prolonged use management unit 12 measures the period of time a user is in individual stall 1, and if that period exceeds a standard period, it performs internal notification control to notify the user of the usage period inside individual stall 1 with sound or light, external notification control to notify the user of the usage period outside individual stall 1 with sound or light, unlocking control to unlock the electric lock (not shown) installed on door 4, and forced opening control of door 4.

[0061] In this embodiment, as shown in Figure 1, an extension operation unit 19 for extending the usage period is provided near the toilet bowl 18. When the extension operation unit 19 is operated, the long-term use management unit 12 extends the standard period. For example, the extension operation unit 19 may be a button switch. If the extension operation unit 19 is operated frequently, the standard period may be considered shorter than an appropriate period for those using the individual room 1 for its intended purpose. Therefore, in the automatic door device 100 of this embodiment, the number of times the extension operation unit 19 has been operated is stored in the memory unit 6. Alternatively, the number of consecutive uses in which the user has operated the extension operation unit 19 to extend the usage time may also be stored. In this case, the memory unit 6 can be used to optimize the standard period for long-term use.

[0062] The long-term use management unit 12, for example, extends the standard period when the number of operations of the extension operation unit 19 during a predetermined period exceeds a standard number. The predetermined period of the long-term use management unit 12 can be set by experiment or simulation as a period during which the validity of the standard period can be judged, and may be, for example, 1 day, 10 days, 30 days, 90 days, 180 days, etc. The standard number of operations of the long-term use management unit 12 can be set by experiment or simulation as a number during which the validity of the standard number can be judged, and may be, for example, 1 time, 10 times, 100 times, etc.

[0063] The automatic door device 100 of this embodiment can selectively or overlappingly perform the following operations, and which operations to perform can be set, for example, in the information processing unit 16. These settings may be switched according to the time of day, season, surrounding environment, occupancy status of the private room, etc., or they may be switched based on the operation of the person who installed the private room.

[0064] [1st action] The first operation for changing the sensitivity of the switch 31 of the automatic door device 100 of this embodiment will be described. Figure 9 is a flowchart illustrating the process S110 of the first operation. When process S110 starts, in step S111, the memory unit 6 stores the number of times the open switch 31 has been turned on N11 and the number of times the entry detection unit 5 has detected the entry of an object or person into the private room 1 N12. When a user uses the private room 1, they pass through the opening 2 and are detected by the entry detection unit 5, so this can be used to estimate the actual number of times the private room 1 has been used.

[0065] In step S112, the information processing unit 16 determines whether a predetermined period T11 has elapsed. Whether a predetermined period T11 has elapsed can be determined using a timer. If the predetermined period T11 has elapsed (Y in step S112), processing S110 proceeds to step S113. If the predetermined period T11 has not elapsed (N in step S112), processing S110 returns to step S111 and repeats steps S111-S112. The predetermined period T11 can be set by experiment or simulation as a period during which unnecessary opening and closing can be determined, and may be, for example, 1 day, 10 days, 30 days, 90 days, 180 days, etc.

[0066] In step S113, the determination unit 7 determines whether the number of times the open switch 31 is turned on N11 is greater than or equal to a certain number of times the entry detection unit 5 detects an entry N12. The certain number of times in this step can be set by experiment or simulation to ensure the validity of the determination, and may be, for example, 1 time, 10 times, 100 times, etc.

[0067] If the number of ON counts N11 is greater than or equal to the number of detection counts N12 of the entry detection unit 5 (Y in step S113), process S110 proceeds to step S114. If the condition that the number of ON counts N11 is greater than or equal to the number of detection counts N12 of the entry detection unit 5 is not met (N in step S113), process S110 proceeds to step S116.

[0068] In step S114, the determination unit 7 determines that unnecessary opening and closing is occurring, and processing S110 proceeds to step S115. In this case, the sensitivity of the open switch 31 is higher than the appropriate level, and it is considered that the automatic door device 100 is being opened and closed by factors other than the user's opening operation. Therefore, it is desirable to lower the sensitivity in order to reduce such unnecessary opening and closing.

[0069] In step S116, the determination unit 7 determines whether the number of times the open switch 31 is turned on N11 is less than or equal to a certain number of times the entry detection unit 5 detects an entry N12. The certain number of times in this step can be set by experiment or simulation to ensure the validity of the determination, and may be, for example, 1 time, 10 times, 100 times, etc.

[0070] If the number of times the open switch 31 is turned on N11 is less than or equal to the number of times the entry detection unit 5 is detected N12 (Y in step S116), then process S110 proceeds to step S117. In this case, the sensitivity of the open switch 31 is considered to be lower than the appropriate level, so it is desirable to increase the sensitivity.

[0071] If the number of times the open switch 31 is turned on N11 is less than or equal to the number of times the entry detection unit 5 is detected N12, the condition (N in step S116) is not met, then process S110 proceeds to step S118. In this case, the sensitivity of the open switch 31 is considered to be at an appropriate level, so it is desirable not to change the sensitivity.

[0072] In step S117, the adjustment unit 8 is modified to increase the sensitivity of the open switch 31, and the process S110 proceeds to step S118.

[0073] In step S115, the adjustment unit 8 is modified to lower the sensitivity of the open switch 31, and the process S110 proceeds to step S118.

[0074] In step S118, the memory unit 6 resets the number of times the open switch 31 is turned on N11 and the number of times the entry detection unit 5 detects an entry N12. The information processing unit 16 also resets a predetermined period T11. After step S118, process S110 ends. Process S110 may be executed repeatedly. Each step of process S110 is illustrative and various modifications are possible.

[0075] According to the first operation, the determination unit 7 can be used to determine whether or not unnecessary opening and closing has occurred. Furthermore, the adjustment unit 8 can be used to automatically change the sensitivity of the open switch 31 to prevent frequent unnecessary opening and closing.

[0076] [Second action] A second operation for changing the sensitivity of the switch 31 of the automatic door device 100 of this embodiment will be described. Figure 10 is a flowchart illustrating the process S210 of the second operation. When process S210 starts, in step S211, the storage unit 6 stores the number of times the contact-type open switch 33 is turned on N21 and the number of times the non-contact-type open switch 31 is turned on N22. If the sensitivity of the switch 31 is appropriate, when the user presses the contact-type open switch 33, the open switch 33 will also be turned on at the same time.

[0077] In step S212, the information processing unit 16 determines whether a predetermined period T21 has elapsed. Whether a predetermined period T21 has elapsed can be determined using a timer. If the predetermined period T21 has elapsed (Y in step S212), processing S210 proceeds to step S213. If the predetermined period T21 has not elapsed (N in step S212), processing S210 returns to step S211 and repeats steps S211-S212. The predetermined period T21 can be set by experiment or simulation to ensure the validity of the judgment, and may be, for example, 1 day, 10 days, 30 days, 90 days, 180 days, etc.

[0078] In step S213, the determination unit 7 determines whether the number of times the contact-type open switch 33 is turned on N21 is greater than or equal to a certain number of times the non-contact-type open switch 31 is turned on N22. The certain number of times in this step can be set by experiment or simulation to ensure the validity of the determination, and may be, for example, 1 time, 10 times, 100 times, etc.

[0079] If the number of ONs N21 is greater than or equal to the reference number of ONs N22 (Y in step S213), process S210 proceeds to step S214. In this case, the sensitivity of the open switch 31 is considered to be lower than the appropriate level, so it is desirable to increase the sensitivity.

[0080] If the number of ON counts N21 is not greater than or equal to the number of ON counts N22 of the intrusion detection unit 5 (N in step S213), the process S210 proceeds to step S215. In this case, the sensitivity of the open switch 31 is considered to be within the appropriate range, so it is desirable not to change the sensitivity.

[0081] In step S214, the adjustment unit 8 is modified to increase the sensitivity of the open switch 31, and the process S210 proceeds to step S215.

[0082] In step S215, the storage unit 6 resets the ON counts N21 and N22. The information processing unit 16 also resets the predetermined period T21. After step S215, process S210 ends. Process S210 may be executed repeatedly. Each step of process S210 is illustrative and various modifications are possible.

[0083] According to the second operation, the sensitivity of the open switch 31 can be determined using the determination unit 7. Furthermore, the sensitivity of the open switch 31 can be automatically changed using the adjustment unit 8.

[0084] [Third action] A third operation for diagnosing the switch 31 of the automatic door device 100 of this embodiment will be described. Figure 11 is a flowchart illustrating the process S310 of the third operation. When process S310 starts, in step S311, the storage unit 6 stores the number of times the non-contact open switch 31 is turned on N31 and the number of times the entry detection unit 5 detects an intrusion N32.

[0085] In step S312, the information processing unit 16 determines whether a predetermined period T31 has elapsed. Whether a predetermined period T31 has elapsed can be determined using a timer. If the predetermined period T31 has elapsed (Y in step S312), processing S310 proceeds to step S313. If the predetermined period T31 has not elapsed (N in step S312), processing S310 returns to step S311 and repeats steps S311-S312. The predetermined period T31 can be set by experiment or simulation to ensure the validity of the judgment, and may be, for example, 1 day, 10 days, 30 days, 90 days, 180 days, etc.

[0086] In step S313, the determination unit 7 determines whether the number of times the non-contact open switch 31 is turned on N31 is less than or equal to a certain number of times the entry detection unit 5 detects an entry N32. The certain number of times in this step can be set by experiment or simulation to ensure the validity of the determination, and may be, for example, 1 time, 10 times, 100 times, etc.

[0087] If the ON count N31 is less than or equal to the detection count N32 by a certain number (Y in step S313), process S310 proceeds to step S314. In this case, it is considered that the non-contact open switch 31 is malfunctioning, and therefore it is desirable to provide notification.

[0088] In step S314, the fault diagnosis unit 9 determines that the non-contact open switch 31 is faulty, and process S310 proceeds to step S317.

[0089] If the condition that the ON count N31 is less than or equal to the detection count N32 is not met (N in step S313), then process S310 proceeds to step S315. In this case, the open switch 31 is considered not to be faulty.

[0090] In step S315, the determination unit 7 determines whether a predetermined condition is met. For example, the predetermined condition in step S315 is that the ON count N31 is at least a certain number greater than the detection count N32. If the predetermined condition is met (Y in step S315), the determination unit 7 determines that unnecessary opening and closing has occurred, and process S310 proceeds to step S317. If the predetermined condition is not met (N in step S315), process S310 proceeds to step S318.

[0091] In step S317, the notification unit 10 performs the aforementioned notification, and processing S310 proceeds to step S318. In other words, in processing S310, the notification unit 10 performs a notification when the determination unit 7 determines that unnecessary opening and closing is occurring, or when the fault diagnosis unit 9 determines that there is a fault.

[0092] In step S318, the memory unit 6 resets the number of times the non-contact open switch 31 is turned on N31 and the number of times the entry detection unit 5 is detected N32. The information processing unit 16 also resets a predetermined period T31. After step S318, process S310 ends. Process S310 may be executed repeatedly. Each step of process S310 is illustrative and various modifications are possible.

[0093] According to the third operation, the determination unit 7 can be used to determine whether unnecessary opening and closing has occurred, and the fault diagnosis unit 9 can be used to determine if the open switch 31 is faulty. In addition, the notification unit 10 can be used to notify that unnecessary opening and closing has occurred and that the open switch 31 is faulty.

[0094] [4th action] A fourth operation for adjusting the sensitivity of the switch 31 of the automatic door device 100 of this embodiment will be described. Figure 12 is a flowchart illustrating the process S410 of the fourth operation. When process S410 starts, in step S411, the storage unit 6 stores the number of specific closing control operations N41 in which specific closing control has been performed.

[0095] In step S412, the information processing unit 16 determines whether a predetermined period T41 has elapsed. Whether or not the predetermined period T41 has elapsed can be determined using a timer. If the predetermined period T41 has elapsed (Y in step S412), processing S410 proceeds to step S413. If the predetermined period T41 has not elapsed (N in step S412), processing S410 returns to step S411 and repeats steps S411-S412. The predetermined period T41 can be set by experiment or simulation from the viewpoint of ensuring the validity of the judgment, and may be, for example, 1 day, 10 days, 30 days, 90 days, 180 days, etc.

[0096] In step S413, the determination unit 7 determines whether the number of specific closing control operations N41 is greater than or equal to a reference number. The reference number in this step can be set by experiment or simulation from the viewpoint of ensuring the validity of the determination, and may be, for example, 1, 10, 100, etc.

[0097] If the number of specific closing control operations N41 is greater than or equal to the reference number (Y in step S413), process S410 proceeds to step S414. In this case, the sensitivity of the non-contact open switch 31 is considered to be higher than the appropriate level.

[0098] In step S414, the determination unit 7 determines that unnecessary opening and closing has occurred, and processing S410 proceeds to step S415.

[0099] If the number of specific closing control operations N41 does not satisfy the condition that it is greater than or equal to the reference number (N in step S413), process S410 proceeds to step S418. In this case, the sensitivity of the open switch 31 is considered to be within the appropriate range.

[0100] In step S415, the adjustment unit 8 is modified to lower the sensitivity of the open switch 31, and the process S410 proceeds to step S416.

[0101] In step S416, the fault diagnosis unit 9 determines that the open switch 31 has failed. In other words, through the processing in steps S413 and S416, the fault diagnosis unit 9 determines that the open switch 31 has failed based on the information in the memory unit 6.

[0102] In step S417, the notification unit 10 performs the aforementioned notification, and processing S410 proceeds to step S418. In other words, in processing S410, the notification unit 10 performs a notification when the determination unit 7 determines that unnecessary opening and closing is occurring, or when the fault diagnosis unit 9 determines that there is a fault.

[0103] In step S418, the storage unit 6 resets the specified closing control count N41. The information processing unit 16 also resets the predetermined period T41. After step S418, process S410 ends. Process S410 may be executed repeatedly. Each step of process S410 is illustrative and various modifications are possible.

[0104] According to the fourth operation, the determination unit 7 can determine whether or not unnecessary opening and closing has occurred based on the number of specific closing control operations. Furthermore, the adjustment unit 8 can automatically change the sensitivity of the open switch 31 to prevent frequent unnecessary opening and closing. In addition, the fault diagnosis unit 9 can diagnose a fault in the open switch 31. Furthermore, the determination unit 7 can determine whether or not unnecessary opening and closing has occurred. In addition, the notification unit 10 can notify that unnecessary opening and closing has occurred and that the open switch 31 has failed.

[0105] [5th ​​action] A fifth operation for diagnosing the automatic door device 100 of this embodiment will now be described. Figure 13 is a flowchart illustrating the process S510 of the fifth operation. When process S510 is started, the storage unit 6 stores the number of times the non-contact open switch 31 is turned on N51 and the number of times the inner close switch 46 is turned on N52 in step S511. When a user uses the private room 1, they need to operate the inner close switch 46 to open the door 4 and go outside, so this can be used to estimate the actual number of times the private room 1 has been used. The number of times N52 is turned on refers to the number of times either one or both of the close switches 42 and 44 are turned on by a single operation by the operator, and if both are turned on, it is counted as one time.

[0106] In step S512, the information processing unit 16 determines whether a predetermined period T51 has elapsed. Whether or not the predetermined period T51 has elapsed can be determined using a timer. If the predetermined period T51 has elapsed (Y in step S512), processing S510 proceeds to step S513. If the predetermined period T51 has not elapsed (N in step S512), processing S510 returns to step S511 and repeats steps S511-S512. The predetermined period T51 can be set by experiment or simulation to ensure the validity of the judgment, and may be, for example, 1 day, 10 days, 30 days, 90 days, 180 days, etc.

[0107] In step S513, the determination unit 7 determines whether or not unnecessary opening and closing has occurred based on the information from the storage unit 6. In this embodiment, the determination unit 7 determines whether the number of times the open switch 31 is turned on N51 is greater than or equal to a reference number of times the inner close switch 46 is turned on N52. The reference number in this step can be set by experiment or simulation from the viewpoint of ensuring the validity of the determination, and may be, for example, 1 time, 10 times, 100 times, etc.

[0108] If the number of times the non-contact open switch 31 is turned on N51 is greater than the standard number (Y in step S513), process S510 proceeds to step S514. In this case, it is considered that the sensitivity of the non-contact open switch 31 is higher than the appropriate level, resulting in unnecessary opening and closing.

[0109] In step S514, the determination unit 7 determines that unnecessary opening and closing has occurred, and processing S510 proceeds to step S515.

[0110] If the number of times the open switch 31 is turned on N51 does not meet the condition that it is greater than or equal to the reference number (N in step S513), process S510 proceeds to step S516. In this case, the sensitivity of the open switch 31 is considered to be within the appropriate range.

[0111] In step S515, the notification unit 10 performs the aforementioned notification, and processing S510 proceeds to step S516. In other words, in processing S510, the notification unit 10 performs a notification when the determination unit 7 determines that an unnecessary opening or closing has occurred.

[0112] In step S516, the storage unit 6 resets the ON counts N51 and N52. The information processing unit 16 also resets the predetermined period T51. After step S516, process S510 ends. Process S510 may be executed repeatedly. Each step of process S510 is illustrative and various modifications are possible.

[0113] According to the fifth operation, the determination unit 7 can be used to determine whether or not unnecessary opening and closing has occurred. In addition, the notification unit 10 can be used to notify that unnecessary opening and closing has occurred.

[0114] The features of the automatic door device 100 of this embodiment will now be described. The automatic door device 100 includes a door 4 provided in the opening 2 of a private room 1 and controlled to open and close, a non-contact open switch 31 provided outside the private room 1 for opening the door 4, an entry detection unit 5 for detecting whether or not someone has entered the private room 1, and a storage unit 6 for storing the number of times the open switch 31 has been turned on and the number of times the entry detection unit 5 has detected an entry.

[0115] This configuration allows for the optimization of the sensitivity of the non-contact open switch 31 using the information from the memory unit 6.

[0116] The automatic door device 100 may also be configured to include a door 4 installed in the opening 2 of the private room 1 and controlled to open and close, a contact-type open switch 33 for opening the door 4, a non-contact open switch 31 positioned to turn on when the contact-type open switch 33 is operated and for opening the door 4, and a storage unit 6 that stores the number of times the contact-type open switch 33 is turned on and the number of times the non-contact open switch 31 is turned on.

[0117] This configuration allows for the optimization of the sensitivity of the non-contact open switch 31 using the information from the memory unit 6.

[0118] Furthermore, the automatic door device 100 may also be configured to include: a door 4 provided in the opening 2 of the private room 1 and controlled to open and close; a non-contact type inner open switch 41 and inner close switch 42 provided on the inside of the private room 1 for opening and closing the door 4; a non-contact type outer open switch 31 and outer close switch 32 provided on the outside of the private room 1 for opening and closing the door 4; a door control unit 16d that controls the opening and closing of the door 4 based on signals from the inner open switch 41, the inner close switch 42, the outer open switch 31 and the outer close switch 32; and a storage unit 6 that stores a specific number of times the door control unit 16d has controlled the door 4 to close after opening the door 4 based on the signal from the outer open switch 31, without relying on signals from the inner close switch 42 and the outer close switch 32.

[0119] This configuration allows for the optimization of the sensitivity of the non-contact open switch 31 using the information from the memory unit 6.

[0120] Furthermore, the automatic door device 100 includes a door 4 provided in the opening 2 of the private room 1 and controlled to open and close, an external open switch 35 provided outside the private room 1 for opening the door 4, an internal close switch 46 provided inside the private room 1 for closing the door 4, and a storage unit 6. The external open switch 35 may include a contact-type open switch 33 and a non-contact-type open switch 31, and the storage unit 6 may be configured to store the number of times the non-contact-type open switch 31 is turned on and the number of times the internal close switch 46 is turned on.

[0121] This configuration allows for the optimization of the sensitivity of the non-contact open switch 31 using the information from the memory unit 6.

[0122] The second to eleventh embodiments of the present invention will be described below. In the drawings and descriptions of the second to eleventh embodiments, the same reference numerals are used for components and members that are the same as or equivalent to those in the first embodiment. Descriptions that overlap with the first embodiment will be omitted as appropriate, and the descriptions will focus on the configurations that differ from the first embodiment.

[0123] [Second Embodiment] A switch 3 for an automatic door device according to a second embodiment of the present invention will now be described. As mentioned above, it is desirable that the sensitivity of the open switches 31 and 41 be appropriately maintained. Therefore, the switch 3 for an automatic door device according to the second embodiment includes contact-type open switches 33 and 43 for opening a door 4 provided in the opening 2 of a private room 1, non-contact-type open switches 31 and 41 for opening the door 4, and a storage unit 6 that stores the number of times the contact-type open switches 33 and 43 are turned on N61 and the number of times the non-contact-type open switches 31 and 41 are turned on N62. In other words, the switch 3 for an automatic door device can also be described as including an open switch for opening a door 4 provided in the opening of a private room and controlled to open and close, which includes a contact-type switch and a non-contact-type switch arranged to be in an operating state simultaneously when at least the contact-type switch is operated, and a storage unit that stores the number of times the contact-type switch is turned on and the number of times the non-contact switch is turned on.

[0124] If the sensitivity of the non-contact switches 31 and 41 is appropriate, the non-contact switches 31 and 41 will turn on before the contact switches 33 and 43 are operated, so the contact switches 33 and 43 will not be operated, and the number of times they are turned on N62 will be greater than the number of times they are turned on N61. Therefore, by comparing the number of times they are turned on N62 and the number of times they are turned on N61 stored in the memory unit 6 during a predetermined period, it is possible to determine whether the sensitivity is appropriate, and if it is determined that it is not appropriate, the sensitivity of the non-contact switches 31 and 41 can be adjusted to an appropriate state. In addition, the automatic door device switch 3 may be equipped with an adjustment unit 8 that increases the sensitivity of the non-contact switches when the number of times the contact switches are turned on exceeds the number of times the non-contact switches are turned on by a certain number or more during a predetermined period.

[0125] As mentioned above, the detection method for the non-contact open switches 31 and 41 is not limited. The automatic door device switch 3 may include all or part of the functional block of the information processing unit 16 in addition to the memory unit 6.

[0126] According to the switch 3 for the automatic door device of the second embodiment, it is possible to diagnose non-contact switches 31 and 41.
