Description

[Technical field]

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

[0002] 2. Description of the Related Art In recent years, from the viewpoint of hygiene, technology for automatic door systems that use non-contact switches to detect operations by a user to open or close a door has become widespread (see, for example, Patent Document 1).

[0003] In the non-contact switch, a judgment time is set to judge whether or not a non-contact operation is performed by the user. The non-contact switch detects a non-contact operation by the user when the time elapsed since an object entered the detection area exceeds the judgment time. This prevents the non-contact switch 53 from erroneously detecting a passerby or a user nearby. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-075510 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, if the above-mentioned judgment time is too long, even if a user operates the non-contact switch, the non-contact switch does not immediately detect the non-contact operation, resulting in a delay in the opening and closing operation of the automatic door.On the other hand, if the above-mentioned judgment time is too short, the non-contact switch is more likely to erroneously detect an operation that is not intended to operate the non-contact switch, such as the hand or luggage of a user or passerby unintentionally entering the detection area of ​​the non-contact switch, and the door is more likely to be opened or closed by mistake.

[0006] In view of the above, an object of the present invention is to provide a technology that prevents unintended opening and closing of a door due to erroneous detection by a non-contact switch, while enabling the door to be opened and closed quickly when necessary.

[0021] The present invention will be described below based on preferred embodiments with reference to the drawings. In the embodiments and modified examples, the same or equivalent components and members are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. Some of the members that are not important for explaining the embodiments are omitted in each drawing.

[0022] (First embodiment) The automatic door system of the first embodiment will be described below.

[0023] Fig. 1 is a plan view showing the configuration of a multi-function toilet in which an automatic door device 5 of the first embodiment is installed. As shown in Fig. 1, the multi-function toilet 1 is a private room with one entrance 2, and a toilet 3 is installed in a large space to make it easy for people with disabilities and people with children to use. An automatic door device 5 is installed at the entrance 2 to drive and control a door 4 that opens and closes the entrance 2. The door 4 is a sliding door. The entrance 2 in this embodiment is an example of an opening.

[0024] An outer door operating device 30 that operates the opening and closing of the door 4 is installed on the outer (outside) wall of the multi-function toilet 1. An inner door operating device 40 that operates the opening and closing of the door 4 is installed on the inner (inside) wall of the multi-function toilet 1. An object detection sensor 12 that detects people and objects passing outside the entrance / exit 2 is installed on the outside of the entrance / exit 2. The object detection sensor 12 detects people and objects that are present in a detection area that is outside the entrance / exit 2 and is a predetermined range from the entrance / exit 2. The object detection sensor 12 outputs a detection signal when it detects a person or object. An auxiliary sensor 13 that detects people standing inside the entrance / exit 2 is installed on the inner wall of the entrance / exit 2. An occupancy sensor 15 that detects users in the private room is installed on the ceiling. The outer door operating device 30 and the inner door operating device 40 of this embodiment are each an example of a switch device.

[0025] 2 is a front view showing the configuration of the outer door operating device 30 and the inner door operating device 40 of the automatic door system 5 of the first embodiment. The outer door operating device 30 and the inner door operating device 40 have the same configuration. The outer door operating device 30 and the inner door operating device 40 are equipped with a contact switch 51 and a non-contact switch 53. The contact switch 51 outputs an opening / closing instruction to open / close the door 4 based on a contact operation of pressing a button switch. The non-contact switch 53 detects a user based on a non-contact operation that does not come into contact with the user and outputs an opening / closing instruction to open / close the door 4. The non-contact switch 53 is built into the outer door operating device 30 and the inner door operating device 40.

[0026] The contact switch 51 includes an open button switch 52a installed on the upper side of each of the outer door operating device 30 and the inner door operating device 40, and a close button switch 52b installed on the lower side of each of the outer door operating device 30 and the inner door operating device 40. "OPEN, ←→, OPEN" is written on the surface of the open button switch 52a. "CLOSED, →←, CLOSE" is written on the surface of the close button switch 52b.

[0027] The non-contact switch 53 includes an open non-contact switch 54a and a close non-contact switch 54b. The open non-contact switch 54a is installed on the upper side of each of the outer door operating device 30 and the inner door operating device 40. The close non-contact switch 54b is installed on the lower side of each of the outer door operating device 30 and the inner door operating device 40. The non-contact switch of this embodiment detects a user based on a reflected wave of an output detection wave. The detection wave here is, for example, an electric wave, a light wave, a sound wave, an infrared ray, or the like. Without being limited thereto, the non-contact switch may include an electrode part whose capacitance changes depending on the proximity of an object, i.e., the distance between the object and the non-contact switch, and may detect a user based on a change in the capacitance of the electrode part 54c. In addition, the non-contact switch may detect a user when a specific posture or action of the user (for example, a posture facing the non-contact switch 53 or an action of putting up a thumb) is detected by image recognition of a detected image. The non-contact switch 53 of this embodiment is an example of a detection part.

[0028] Fig. 3 is a functional block diagram of the automatic door system 5 of the first embodiment. Each functional block shown in Fig. 3 can be realized in hardware terms by computer processors, CPUs, memory and other elements, electronic circuits, and mechanical devices, and in software terms by computer programs, etc., but the functional blocks shown here are realized by the cooperation of these. Therefore, those skilled in the art will understand that these functional blocks can be realized in various ways by combining hardware and software. The same applies to Fig. 5 described below.

[0029] The automatic door device 5 includes a door engine 11 for driving the door 4, an auxiliary sensor 13, an electric lock 14, a door controller 10 to which these devices are connected, an object detection sensor 12, a room occupancy sensor 15, an outer door operating device 30, and an inner door operating device 40. The door controller 10, the object detection sensor 12, and the room occupancy sensor 15 are connected to a CAN 50. The auxiliary sensor 13 transmits a detection signal to the door controller 10 upon detection. The object detection sensor 12 and the room occupancy sensor 15 transmit a detection signal to the door controller 10 via the CAN 50 upon detection. The door controller 10 controls the driving of the door engine 11 according to the detection results of the object detection sensor 12, the auxiliary sensor 13, and the room occupancy sensor 15. The door controller 10 includes a door control unit 10A for controlling the opening and closing of the door 4 based on an open command or a close command.

[0030] Each of the outer door operating device 30 and the inner door operating device 40 further includes a position acquisition unit 56 , a determination unit 57 , an operation determination unit 58 , and an instruction output unit 59 .

[0031] When the open button switch 52a of each of the outer door operating device 30 and the inner door operating device 40 detects a contact operation by the user, it outputs a contact open detection signal to the instruction output unit 59. When the close button switch 52b of each of the outer door operating device 30 and the inner door operating device 40 detects a contact operation by the user, it outputs a contact close detection signal to the instruction output unit 59. In the contact switch 51, a push operation corresponds to a contact operation by the user.

[0032] The open non-contact switch 54a of each of the outer door operating device 30 and the inner door operating device 40 outputs a non-contact open detection signal to the operation determination unit 58 in a state in which a user is detected (hereinafter referred to as a detection state). The close non-contact switch 54b of each of the outer door operating device 30 and the inner door operating device 40 outputs a non-contact close detection signal to the operation determination unit 58 in the detection state.

[0033] The position acquisition unit 56 acquires position information of the door 4. For example, the position acquisition unit 56 can acquire information of an encoder (not shown) of a motor provided in the door engine 11 as position information of the door 4 through the door controller 10.

[0034] The determination unit 57 determines a judgment time for determining whether or not a non-contact operation has been performed by a user based on the door position information. The determination unit 57 of this embodiment sets the judgment time to a first time and a second time that is smaller than the first time. A method for determining the judgment time will be described later.

[0035] The operation determination unit 58 determines whether or not a non-contact operation has been performed by the user based on the detection result of the non-contact switch 53. In this embodiment, the operation determination unit 58 determines that a non-contact operation has been performed by the user when the detection state of the non-contact switch 53 continues for a determination time described below, that is, when a state in which a non-contact open detection signal or a non-contact close detection signal is input from the open non-contact switch 54a or the closed non-contact switch 54b continues for a determination time described below. In the case of the non-contact switch 53, an operation of bringing a part of the user's body or an object close to the switch corresponds to the non-contact operation by the user.

[0036] The instruction output unit 59 outputs an open instruction or a close instruction for the door provided at the opening of the private room when the non-contact switch 53 detects a user. For example, when the operation determination unit 58 determines that a non-contact operation has been performed by the user, the instruction output unit 59 outputs an open instruction or a close instruction to the door control unit 10A. In addition, the instruction output unit 59 outputs an open instruction or a close instruction to the door control unit 10A in response to an open contact detection signal or a close contact detection signal from the contact switch 51.

[0037] FIG. 4 is a flowchart illustrating a process S100 of the door operating device of the first embodiment.

[0038] In step S101 , the position acquisition unit 56 acquires the position information of the door 4 .

[0039] In step S102, the determination unit 57 determines whether the door 4 is in the fully closed position. If the door 4 is in the fully closed position (Y in step S102), the process S100 proceeds to step S103. If the door 4 is not in the fully closed position (N in step S102), the process S100 proceeds to step S104.

[0040] In step S103, the determination unit 57 sets the judgment time to a first time. The first time is, for example, 1 second. After step S103, the process S100 proceeds to step S105.

[0041] In step S104, the determination unit 57 sets the judgment time to the second time. The second time is, for example, 0.5 seconds. After step S104, the process S100 proceeds to step S105.

[0042] In step S105, the operation determination unit 58 determines whether the detection state of the non-contact switch 53 has continued for the determination time determined in step S103 or S104. If it has continued (Y in step S105), the process S100 proceeds to step S106. If it has not continued (N in step S105), the process S100 ends.

[0043] In step S106, the instruction output unit 59 determines whether or not the signal input from the non-contact switch 53 is a non-contact open detection signal. If the input signal is a non-contact open detection signal (Y in step S106), the process S100 proceeds to step S107. If the input signal is not a non-contact open detection signal, i.e., a non-contact close detection signal (N in step S106), the process S100 proceeds to step S108.

[0044] In step S107, the instruction output unit 59 outputs an open instruction to the door control unit 10A in response to the non-contact open detection signal. As a result, the door 4 is opened by the door control unit 10A.

[0045] In step S108, the instruction output unit 59 outputs a close instruction to the door control unit 10A in response to the first close detection signal. As a result, the door 4 is closed by the door control unit 10A.

[0046] After step S108, the process S100 ends.

[0047] As described above, in the first embodiment, each of the outer door operating device 30 and the inner door operating device 40 includes the non-contact switch 53 that detects a user without contacting the user, the position acquisition unit 56 that acquires the position of the door 4, the determination unit 57 that determines a judgment time based on the position of the door 4, and the instruction output unit 59 that outputs an open instruction or a close instruction when the state in which the user is detected by the non-contact switch 53 continues for the determined judgment time. According to this configuration, whether to output an open instruction or a close instruction is determined based on the judgment time determined based on the position of the door 4, so that it is possible to quickly open and close the door 4 when necessary while suppressing unintended opening and closing of the door due to erroneous detection by the non-contact switch 53.

[0048] In the first embodiment, the determination unit 57 sets the determination time to be longer when the door 4 is in the fully closed position than when the door 4 is not in the fully closed position. Here, when the door 4 is in the fully closed position, the multi-function toilet 1 is in use or in standby for use. Therefore, when the multi-function toilet 1 is in use, it is necessary to prevent the open non-contact switch 54a of the inner door operating device 40 from erroneously detecting the user's body or luggage, causing the door 4 to open undesirably, and when the multi-function toilet 1 is in standby for use, it is necessary to prevent the open non-contact switch 54a of the outer door operating device 30 from erroneously detecting a pedestrian passing nearby, causing the door 4 to open unnecessarily. On the other hand, when the door 4 is in a position other than the fully closed position, it is appropriate to improve the response of the non-contact switch 53, for example, when the user operates the non-contact switch 53. According to this configuration, it is possible to further suppress erroneous detection when the door 4 is in the fully closed position, and it is possible to quickly operate the door 4 when the door 4 is in a position other than the fully closed position. Therefore, it is possible to effectively improve the convenience of the user with respect to the non-contact switch 53.

[0049] A modification of the first embodiment will now be described.

[0050] In the embodiment, the outer door operating device 30 and the inner door operating device 40 are provided with the contact switch 51, but are not limited thereto and may not be provided with the contact switch 51.

[0051] In the embodiment, the determination unit 57 sets the duration of the detection state of the non-contact switch 53 as the judgment time and changes this depending on the position of the door 4, but the judgment time may be the time until it is determined that the non-contact switch 53 is in a state in which it is detecting a user and change this depending on the position of the door 4. In this case, the non-contact switch 53 determines that it is in a detection state when a state in which the reflection amount of the detection wave is equal to or greater than a reference value continues for a reference time, and the determination unit 57 changes the reference time depending on the position of the door 4.

[0052] In the embodiment, in step S102, the determination unit 57 determines whether the door 4 is in the fully closed position, but this is not limiting, and the determination unit 57 may determine whether the door 4 is moving. At this time, if the door 4 is not moving, the process S100 proceeds to step S103, and if the door 4 is moving, the process S100 proceeds to step S104. That is, if the door 4 is moving, the determination unit 57 shortens the determination time compared to when the door 4 is not moving. With this configuration, it is possible to quickly reverse the door 4 in the opposite direction during the opening or closing operation using the non-contact switch 53.

[0053] Further, the operation determination unit 58 may have a reference determination time in advance, and the decision unit 57 may change the reference determination time depending on the position of the door 4.

[0054] 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.

[0055] 5 is a functional block diagram of the automatic door device 5 of the second embodiment. Each of the outer door operating device 30 and the inner door operating device 40 of the second embodiment includes an image acquiring unit 60 and a congestion level estimating unit 61 instead of the position acquiring unit 56 of the first embodiment. The image acquiring unit 60 acquires images of the surroundings of the automatic door device 5. The congestion level estimating unit 61 estimates the congestion level of the surroundings of the automatic door device 5.

[0056] Fig. 6 is a flow chart illustrating the process S200 of the door operating device of the first embodiment. Steps S204 to S209 of the process S200 in Fig. 6 are similar to steps S103 to S108, and therefore the description thereof will be omitted.

[0057] In step S201, the image acquisition unit 60 acquires an image in front of the exterior door 4 of the multi-function toilet 1. The image acquisition unit 60 acquires an image, for example, from a camera (not shown) attached to the automatic door device 5 or its periphery outside the multi-function toilet 1.

[0058] In step S202, the congestion degree estimation unit 61 estimates the congestion degree in front of the exterior door 4 of the multi-function toilet 1 based on the acquired image. The congestion degree estimation unit 61 of this embodiment calculates the density of people in front of the exterior door 4 of the multi-function toilet 1 by, for example, executing image recognition processing on the acquired image, and estimates the congestion degree based on this density.

[0059] In step S203, the determination unit 57 determines whether the congestion degree is greater than a predetermined congestion reference value. If the congestion degree is greater than the predetermined congestion reference value (Y in step S203), the process S200 proceeds to step S204. If the congestion degree is not greater than the predetermined congestion reference value (N in step S203), the process S100 proceeds to step S205.

[0060] Here, when the area around the automatic door device 5 is crowded, many pedestrians pass near the non-contact switch 53, which makes it easier for the non-contact switch 53 to erroneously detect the same. In contrast, in the second embodiment, the outer door operating device 30 includes a congestion degree estimation unit 61 that estimates the congestion degree of the area around the automatic door device 5, a determination unit 57 that determines a judgment time based on the congestion degree, and an instruction output unit 59 that outputs an open instruction or a close instruction when the state in which the non-contact switch 53 detects a user continues for the determined judgment time. According to this configuration, whether to output an open instruction or a close instruction is determined based on the judgment time determined based on the congestion degree, so that it is possible to quickly open and close the door 4 when necessary while suppressing erroneous detection of an operation that is not intended to operate the non-contact switch 53, such as detection of a pedestrian by the non-contact switch 53.

[0061] In the second embodiment, when the degree of congestion on the outside of the multi-function toilet 1 is greater than a predetermined congestion standard value, the decision unit 57 makes the judgment time longer than when the degree of congestion on the outside of the multi-function toilet 1 is equal to or less than the predetermined congestion standard value. With this configuration, it is possible to further reduce false positives when the area around the automatic door device 5 is crowded, and to quickly operate the door 4 when the area around the automatic door device 5 is not crowded. This makes it possible to effectively improve the convenience of the non-contact switch 53 for users.

[0062] A modification of the second embodiment will now be described.

[0063] In the second embodiment, the degree of congestion in front of the door 4 on the exterior side of the multi-function toilet 1 is estimated, but this is not limited to this. For example, the degree of congestion in front of the door 4 on the interior side may be estimated by a sensor provided on the interior side of the multi-function toilet 1, such as the presence sensor 15. In this case, the detection method and original use of the sensor are not limited. In this case, the determination unit 57 makes the judgment time longer when the degree of congestion in the interior of the multi-function toilet 1 is greater than a predetermined congestion standard value than when the degree of congestion in the interior of the multi-function toilet 1 is equal to or less than the predetermined congestion standard value.

[0064] In this case, the crowdedness estimation unit 61 may determine the number of people in the multi-function toilet 1 and estimate the crowdedness based on the number of people, and the determination unit 57 may make the determination time longer when there are multiple people in the multi-function toilet 1 than when there are no multiple people in the multi-function toilet 1. For example, the crowdedness estimation unit 61 may determine that there are multiple people in the multi-function toilet 1 when a presence sensor having a detection area consisting of multiple detection spots is in a detection state at multiple detection spots. In addition, the number of people in the multi-function toilet 1 can be determined by performing image recognition processing on an image when a user enters the multi-function toilet 1. Here, when multiple people, such as a parent and child, enter the multi-function toilet 1, the hands or luggage of the person who entered the multi-function toilet 1 are more likely to unintentionally enter the detection area of ​​the non-contact switch 53, making it more likely that erroneous detection will occur in the non-contact switch 53. According to this configuration, even when there are multiple people in the multi-function toilet 1, erroneous detection of the non-contact switch 53 can be effectively suppressed.

[0065] Also, for example, the crowdedness estimation unit 61 may estimate the crowdedness based on the size and amount of luggage of the person in the multi-function toilet 1, and the determination unit 57 may make the judgment time longer when the size and amount of luggage are larger than the standard than when they are equal to or smaller than the standard. For example, the crowdedness estimation unit 61 can determine that the size and amount of luggage are larger than the standard when the range of the spots of the detection state of the presence sensor is equal to or larger than a certain range. Also, the crowdedness estimation unit 61 can determine the size and amount of luggage by performing image recognition processing on the image of the user entering the toilet. Here, for example, if a person who enters the multi-function toilet 1 is carrying large luggage or multiple luggage, the luggage is more likely to unintentionally enter the detection area of ​​the non-contact switch 53, and therefore erroneous detection of the non-contact switch 53 is more likely to occur. According to this configuration, even if a person who enters the multi-function toilet 1 is carrying large luggage or multiple luggage, erroneous detection of the non-contact switch 53 can be effectively suppressed.

[0066] In the second embodiment, the congestion degree is estimated based on the actual situation in front of the exterior door 4 of the multi-function toilet 1, but is not limited to this. For example, the congestion degree estimation unit 61 may estimate the congestion degree to be higher during times when the facility in which the automatic door device 5 is installed is crowded than during times when it is not crowded. For example, if the multi-function toilet 1 is provided near an airplane boarding lounge at an airport, the congestion degree estimation unit 61 may estimate the congestion degree to be higher during times when airplanes arrive. Also, if the multi-function toilet 1 is provided in a train station, the congestion degree estimation unit 61 may estimate the congestion degree to be higher during train rush hours.
