Description

[Technical Field]

[0001] The present invention relates to an automatic door system, an automatic door switch, a control method for an automatic door switch, and a control program for an automatic door switch. [Background technology]

[0002] Automatic door systems are known that use non-contact switches to control the opening and closing operations of an opening / closing body. For example, Patent Document 1 describes a roller blind device that controls the opening and closing operations of a screen curtain in accordance with the detection state of a non-contact switch means (area sensor). This device includes an opening / closing means that opens and closes the opening, an area sensor that detects the approach of a finger in a non-contact manner, and an opening / closing control means that controls the opening and closing operations of the opening / closing means in accordance with the detection state of the area sensor. In this device, two or more area sensors are arranged adjacent to each other, and each sensor enters one of multiple detection states when a finger is held over one or both of the sensors. The control means controls the opening and closing operations in accordance with the multiple detection states. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-095940 Summary of the Invention [Problem to be solved by the invention]

[0004] In the device of Patent Document 1, there are four types of two area sensors: when both sensors are in a detection state, when one sensor is in a detection state, and when neither sensor is in a detection state. When both sensors are in a detection state, it corresponds to a stop operation, and when one sensor is in a detection state, it corresponds to an open operation and a close operation, respectively, to control the opening and closing stop operation.

[0005] The device of Patent Document 1 is controlled based on only two states: a detection state and a non-detection state of the sensor. However, there are various ways in which fingers are held over the two sensors, and the operation intended by the user cannot always be detected based on only two states: a detection state and a non-detection state of the sensor. Therefore, if the device is controlled based on only two states, there is a concern that the device may operate in a manner different from the user's intention. In other words, the device of Patent Document 1 is not sufficient from the viewpoint of reliably performing the operation intended by the user.

[0006] The present invention has been made in consideration of these problems, and one of its objects is to provide technology for an automatic door system that can increase the reliability of performing the operation intended by the user. [Means for solving the problem]

[0007] To solve the above problems, one aspect of the present invention provides an automatic door system that includes a non-contact door-opening switch that detects a user's action as a response amount, a non-contact door-closing switch that is located near the opening switch and also detects the user's action as a response amount, a determination unit that determines the control content for the door based on the response amounts of the opening switch and the closing switch, and a control unit that controls the opening and closing of the door based on the determination result of the determination unit. If the response amount of either the opening switch or the closing switch exceeds a threshold, the determination unit determines the control content associated with that switch as the control content, and if the response amounts of both the opening switch and the closing switch exceed the threshold, the determination unit determines the control content based on the difference between the response amounts of the two switches.

[0008] Any combination of the above, or mutual substitution of the components or expressions of the present invention among methods, devices, programs, temporary or non-temporary storage media on which programs are recorded, systems, etc., are also valid aspects of the present invention. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a technology for an automatic door system that can increase the reliability of the operation intended by the user being performed. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a front view schematically showing an automatic door system according to an embodiment of the present invention; [Figure 2] FIG. 2 is a block diagram showing the automatic door system of FIG. 1. [Figure 3] FIG. 10 is a diagram schematically showing a change in the reaction amount of the detection unit. [Figure 4] FIG. 2 is a diagram schematically illustrating a detection unit. [Figure 5] 4 is a flowchart showing an example of the operation of the automatic door switch according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0011] Among the embodiments disclosed in this specification, those that are comprised of multiple objects may be integrated, and conversely, those that are comprised of a single object may be separated into multiple objects. Regardless of whether they are integrated, it is sufficient that they are configured to achieve the object of the invention.

[0012] 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 integrated together, and conversely, those in which multiple functions are provided in a distributed manner may have some or all of the multiple functions integrated together. Regardless of whether the functions are integrated or distributed, it is sufficient that the configuration can achieve the object of the invention.

[0013] Furthermore, separate components that share something in common are distinguished by prefixing their names with "first," "second," etc., and these are omitted when referring to them collectively. Furthermore, terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and do not limit the components.

[0014] An automatic door system according to one embodiment includes a non-contact door-opening switch that detects a user's action as a response amount; a non-contact door-closing switch located adjacent to the opening switch that also detects the user's action as a response amount; a determination unit that determines a control action for the door based on the response amounts of the opening switch and the closing switch; and a control unit that controls the opening and closing of the door based on the determination result of the determination unit. If the response amount of either the opening switch or the closing switch exceeds a threshold, the determination unit determines the control action associated with that switch as the control action; and if the response amounts of both the opening switch and the closing switch exceed the threshold, the determination unit determines the control action based on the difference between the response amounts of the two switches. Note that, in this specification, "threshold" means a preset value, "below the threshold" means "below a predetermined value" or "within a predetermined range," "above the threshold" means "above a predetermined value," and "exceeding the threshold" means "exceeding a predetermined value."

[0015] According to this configuration, the control content of the door is determined based on the amount of both reactions, so the user's intention can be predicted from the amount of both reactions, and the control content can be determined according to the prediction result.

[0016] For example, when the reaction amounts of both the open switch and the close switch exceed a threshold and the difference between the reaction amounts of the open switch and the close switch is equal to or greater than a threshold, the determination unit may determine the control content to be the content associated with the switch with the larger reaction amount. In this case, the control is performed using the content associated with the detector with the larger reaction amount, thereby realizing door operation in line with the user's intention.

[0017] For example, when the reaction amounts of both the open switch and the close switch exceed a threshold and the difference between the reaction amounts of the open switch and the close switch is equal to or less than the threshold, the determination unit may invalidate the determination of the control content based on the reaction amounts of the open switch and the close switch. In this case, invalidating the detection result can prevent the door from operating in a manner that is not in line with the user's intention.

[0018] For example, the automatic door system may further include a notification unit that notifies the user when the determination unit invalidates the control content determination. In this case, feedback can be provided to the user that the control content determination has been invalidated.

[0019] An automatic door switch in one embodiment includes a plurality of detectors located close to each other and each detecting a user's action as a response amount, a determination unit that determines the control content for the door of the automatic door driving device based on the response amounts of the plurality of detectors, and an output unit that outputs the control content determined by the determination unit to the automatic door driving device. When the response amounts of two or more of the plurality of detectors exceed a threshold and the difference between the response amounts of the two or more detectors is equal to or greater than the threshold, the determination unit determines the control content based on the difference between the response amounts of the two or more detectors.

[0020] According to this configuration, the control content of the door is determined based on the response amount of each detection unit, so the user's intention can be predicted from each response amount, and the control content can be determined according to the prediction result.

[0021] For example, when the reaction amounts of two or more detectors exceed a threshold and the difference between the reaction amounts of the two or more detectors is equal to or greater than a threshold, the determination unit of the switch may determine the control content to be the content associated with the detector with the larger reaction amount among the two or more detectors. In this case, the control is performed using the content associated with the detector with the larger reaction amount, thereby realizing door operation in line with the user's intention.

[0022] For example, when the reaction amounts of two or more detectors exceed a threshold and the difference between the reaction amounts of the two or more detectors is equal to or less than the threshold, the determination unit of the switch may invalidate the determination of the control content based on the reaction amounts of the two or more detectors. In this case, invalidating the detection result can prevent the door from operating in a manner that is not in line with the user's intention.

[0023] For example, the plurality of detectors of the switch may be door open / close switches, in which case an automatic door switch can be constructed inexpensively.

[0024] The present invention will be described below based on preferred embodiments with reference to the drawings. In the embodiments and modifications, identical or equivalent components and members are designated by the same reference numerals, and redundant explanations will be omitted where appropriate. The dimensions of the members in the drawings are enlarged or reduced as appropriate for ease of understanding. Some members that are not important for explaining the embodiments will be omitted from the drawings.

[0025] [First embodiment] An automatic door system 100 according to a first embodiment of the present invention will now be described with reference to the drawings. As an example, the automatic door system 100 is a device that opens and closes doors to open or close entrances to walls or other structures that separate spaces in various facilities such as train stations, hotels, department stores, hospitals, and elderly care facilities. Figure 1 is a front view showing a schematic view of the automatic door system 100 according to this embodiment. This figure shows the automatic door system 100 applied to a toilet room used as a multi-function toilet.

[0026] Figure 2 is a block diagram showing the automatic door system 100 according to the present invention. Each block shown in Figure 2 can be realized in terms of hardware using computer processors, CPUs, memory, and other elements, electronic circuits, and mechanical devices, and in terms of software using computer programs, etc. However, the diagram shows functional blocks realized by the cooperation of these elements. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various ways by combining hardware and software.

[0027] As shown in FIG. 2, the automatic door system 100 includes an automatic door switch 10 and an automatic door drive device 90 that drives the door 9 to open and close. The automatic door switch 10 detects the user's actions and transmits control information determined based on the detection results to the automatic door drive device 90. The automatic door drive device 90 includes a control unit 91 and a door engine 92. The control unit 91 controls the door engine 92 to open and close the door 9 based on the control information from the automatic door switch 10. There are no limitations on the transmission path 96 that transmits the control information from the automatic door switch 10, but the transmission path 96 in this example includes an internal device bus. The door engine 92 rotates a drive motor (not shown) to open and close the door 9 based on the control of the control unit 91.

[0028] First, the automatic door switch 10 will be described. The automatic door switch 10 has an information processing unit 20, multiple detection units 4, and push button switches 22 and 23. The information processing unit 20 is equipped with a determination unit 5, an output unit 8, a memory unit 3, and an input unit 25. The memory unit 3 can store acquired information and intermediate processed information in chronological order. The memory unit 3 can also store a control program P100, which will be described later. The input unit 25 acquires the reaction amounts of the first detection unit 11 and the second detection unit 12. The input unit 25 acquires the operation results of the push button switches 22 and 23. The first detection unit 11 is exemplified as a non-contact door open switch, and the second detection unit 12 is exemplified as a non-contact door close switch.

[0029] The pushbutton switches 22, 23 include an open pushbutton switch 22 and a close pushbutton switch 23. When the open pushbutton switch 22 is pressed, the information processing unit 20 outputs control information to the control unit 91, the control content of which is to open the door 9, and when the close pushbutton switch 23 is pressed, the information processing unit 20 outputs control information to the control unit 91, the control content of which is to close the door 9. In other words, the user can open and close the door 9 using the pushbutton switches 22, 23.

[0030] The multiple detectors 4 are provided separately from the pushbutton switches 22 and 23 to detect instructions from the user to open or close the door 9. The multiple detectors 4 are provided close to each other and each detects the user's movement as a response. The detectors 4 being arranged close to each other include a state in which the detectors 4 are arranged within a range where the user can operate them without changing their standing position, or a state in which the detectors 4 are arranged within the length of the user's hand (e.g., 18 cm). In this example, the detectors 4 are arranged on a single control panel. As an example, the detectors 4 may be non-contact switches that detect the user's movement based on a known detection principle. Examples of such detection principles include capacitance, ultrasound, microwaves, and light (e.g., infrared rays). The response of the detector 4 is a physical quantity generated depending on the distance from the user's finger when the user approaches the detector. This may be analog information such as a voltage value, or digital information corresponding to the physical quantity. Below, an example in which the response quantity is analog information is described.

[0031] Each of the multiple detectors 4 is associated with a preset control content related to the operation of the door 9. In other words, a control content is defined in advance for each detector 4. In the example of FIG. 2, the multiple detectors 4 include a first detector 11 and a second detector 12. In this example, the first detector 11 is associated with a control content including a control for opening the door 9, and the second detector 12 is associated with a control content including a control for closing the door 9.

[0032] The multiple detectors 4 may include three or more detectors. For example, the multiple detectors 4 may include detectors associated with control content including control to stop the door 9 during an opening or closing operation.

[0033] Changes in the reaction amount of the detection unit 4 will be described with reference to FIG. 3. FIG. 3 is a diagram schematically illustrating changes in the reaction amount of the detection unit 4. The horizontal axis of FIG. 3 represents the elapsed time when a finger approaches, and the vertical axis represents the reaction amount g1. In this diagram, the reaction amount g1 represents the change relative to a reference value. As shown in this diagram, the reaction amount g1 not only exhibits monotonous changes but also exhibits diverse fluctuations. When the reaction amount g1 is near a threshold, chattering may occur, in which the reaction amount g1 alternates between an ON state in which the reaction amount g1 exceeds the threshold and an OFF state in which the reaction amount g1 does not exceed the threshold. In this specification, the "state exceeding the threshold" refers to a state in which the chattering converges and the reaction amount continues to exceed the threshold. For example, the state in which the reaction amount continues to exceed the threshold for a predetermined period (e.g., 10 ms to 100 ms). The threshold and the predetermined period can be experimentally set so that the effect of chattering is below a desired level. Hereinafter, the state in which the reaction amount exceeds the threshold may be referred to as the "detection state," and the state in which the reaction amount does not exceed the threshold may be referred to as the "detection state." An example in which the plurality of detectors 4 are first detector 11 and second detector 12 will be described below.

[0034] The determination unit 5 determines the control content for the door based on the reaction amounts of the first detection unit 11 and the second detection unit 12. The output unit 8 outputs the control content determined by the determination unit 5 to the control unit 91 of the automatic door driving device 90.

[0035] In this embodiment, when the reaction amount of one of the first detection unit 11 and the second detection unit 12 exceeds the threshold and the reaction amount of the other detection unit does not exceed the threshold, the determination unit 5 determines the control content associated with one of the detection units. In other words, when the reaction amount of the first detection unit 11 exceeds the threshold as the user's finger approaches, the door 9 opens, and when the reaction amount of the second detection unit 12 exceeds the threshold as the user's finger approaches, the door 9 closes.

[0036] The detection unit 4 will be described with reference to FIG. 4. FIG. 4 is a schematic diagram of the detection unit 4. This diagram is a side view of a state in which a user approaches the first detection unit 11 with the intention of opening the door. As shown in this diagram, when the user approaches the first detection unit 11, the user's finger also approaches the second detection unit 12. At this time, the first detection unit 11 and the second detection unit 12 detect reaction amounts according to the approach state, and both reaction amounts may exceed a threshold. Therefore, in this embodiment, when the reaction amounts of both the first detection unit 11 and the second detection unit 12 exceed a threshold, the determination unit 5 determines the control content of the door 9 based on the difference between the reaction amounts. Here, determining the control content based on the difference between the reaction amounts includes determining the control content based on the difference between the two reaction amounts, as well as determining the control content based on the result obtained by performing a predetermined calculation on both, such as the ratio between the two. When the reaction amounts of two or more detection units among the multiple detection units 4 exceed a threshold, the determination unit 5 determines the control content based on the reaction amounts of the two or more detection units.

[0037] Although there are no limitations on the processing of the determination unit 5, in the case where the reaction amounts of both the first detection unit 11 and the second detection unit 12 exceed the threshold and the difference between the reaction amounts of the first detection unit 11 and the second detection unit 12 is equal to or greater than the second threshold, the determination unit 5 of this embodiment determines the control content associated with the detection unit with the larger reaction amount, either the first detection unit 11 or the second detection unit 12. That is, in the case of Fig. 4, the reaction amount of the first detection unit 11 is larger than the reaction amount of the second detection unit 12, so the determination unit 5 determines the door-opening operation associated with the first detection unit 11 as the control content.

[0038] Even if one of the reaction amounts is large, if the difference between the two reaction amounts is small, it is possible that a part of the user's body, such as the shoulder, or clothing may have unintentionally approached the detection unit. In such a case, it is desirable to prevent the door from malfunctioning. Therefore, in this embodiment, when the reaction amounts of both the first detection unit 11 and the second detection unit 12 exceed the threshold, if the difference between the reaction amounts of the first detection unit 11 and the second detection unit 12 is within a predetermined range, i.e., if the difference is equal to or less than the second threshold, the determination unit 5 invalidates the determination of the control content based on the reaction amounts of the first detection unit 11 and the second detection unit 12.

[0039] Here, "invalidating the determination of the control content" means that even if the reaction amount of a detection unit exceeds the threshold, the determination unit 5 does not output the control content based on the detection result of that detection unit. For example, when the determination of the control content based on the detection results of the first detection unit 11 and the second detection unit 12 is invalidated, even if the reaction amount of one or both of these units exceeds the threshold, the determination unit 5 does not control the operation of the door 9 associated with them. The operation of invalidating the determination of the control content continues until the difference in the reaction amount between the first detection unit 11 and the second detection unit 12 exceeds the second threshold.

[0040] See FIGS. 1 and 2. A possible example of a case in which the determination of the control content is invalidated is when, for example, a user holds their hand over the first detection unit 11 intending to open the door, but the second detection unit 12 also produces a similar amount of response due to clothing or other factors, resulting in the process being invalid. In this case, it is desirable to provide feedback to the user that the process has been invalidated due to simultaneous input to both detection units. Therefore, this embodiment further includes an alarm unit 7 that notifies the determination unit 5 of the invalidation of the determination of the control content of the first detection unit 11 and the second detection unit 12 when the determination unit 5 invalidates the determination of the control content of the first detection unit 11 and the second detection unit 12. The alarm unit 7 may output a signal, such as light, sound, or a screen display, that can be noticed by an outside person. In this embodiment, the alarm unit 7 causes the light-emitting device 72 to emit light in response to the notification result. Furthermore, the determination of the control content may be invalidated due to a malfunction of the detection unit, and in this case, the administrator can be prompted to take action.

[0041] The automatic door switch 10 may include multiple detection units 4. In the case where multiple detection units 4 are included, the determination unit 5 may determine the control content based on the reaction amounts of two or more of the multiple detection units 4 when the reaction amounts of two or more of the multiple detection units 4 exceed a threshold. Furthermore, when the reaction amounts of two or more of the multiple detection units 4 exceed a threshold, the determination unit 5 may determine the control content associated with the detection unit with the largest reaction amount among the two or more detection units. Furthermore, when the reaction amounts of two or more of the multiple detection units 4 exceed a threshold, the determination unit 5 may invalidate the determination of the control content of the multiple detection units 4 when the difference in the reaction amounts of the two or more detection units is within a predetermined range.

[0042] An example of the operation of the automatic door switch 10 of this embodiment will be described below. Figure 5 is a flowchart showing the operation S110 of the automatic door switch 10.

[0043] When the operation S110 is started, the determination unit 5 acquires the reaction amounts of the plurality of detection units 4 (step S111).

[0044] Next, the determination unit 5 determines whether one or more of the reaction amounts of the multiple detection units 4 exceeds the threshold (step S112). If none of the reaction amounts exceeds the threshold (N in step S112), the determination unit 5 returns the process to the beginning of step S111 and repeats steps S111 to S112.

[0045] If one or more reaction amounts exceed the threshold (Y in step S112), the determination unit 5 determines whether a predetermined time has elapsed (step S113). If the predetermined time (e.g., 100 ms-1 s) has not elapsed (N in step S113), the determination unit 5 returns the process to the beginning of step S113 and repeats step S113. If the predetermined time has elapsed (Y in step S113), the determination unit 5 determines whether two or more of the reaction amounts of the multiple detection units 4 exceed the threshold (step S114).

[0046] If the judgment condition of step S114 is not satisfied, that is, if the reaction amount of only one detector 4 exceeds the threshold (N in step S114), the determination unit 5 determines the control content to be the content associated with the detector 4 whose reaction amount exceeds the threshold (step S115). After executing this step, the process proceeds to step S119.

[0047] If two or more of the reaction amounts exceed the threshold (Y in step S114), the determination unit 5 determines whether the difference in the reaction amounts of the two or more detection units is within a predetermined range (step S116).

[0048] If the difference in reaction amount is within a predetermined range (Y in step S116), the decision unit 5 invalidates the decision on the control content of the plurality of detection units 4 (step S117). After this step is executed, operation S110 ends.

[0049] If the difference in reaction amount is large and the judgment condition of step S116 is not satisfied (N in step S116), the determination unit 5 determines the control content to be the content associated with the detection unit 4 with the largest reaction amount among the two or more detection units 4 (step S118). After executing this step, the process proceeds to step S119.

[0050] In step S119, the output unit 8 outputs the control content determined by the determination unit 5 to the automatic door driving device 90 (step S119). After this step is executed, operation S110 ends. Operation S110 may be executed repeatedly. The above steps are merely examples, and various modifications are possible.

[0051] The above is the description of the first embodiment.

[0056] These functions of the program P100 may be installed in the storage (e.g., memory unit 3) of the automatic door switch 10 as an application program that implements multiple modules corresponding to the functional blocks of the automatic door switch 10. The program P100 may be read into the main memory of a processor (e.g., CPU) of a computer incorporated in the automatic door switch 10 and executed.
