Description

  The present invention relates to a control device that performs opening control for opening an automatic door.

  Automatic doors are used in various buildings. When the passer tries to pass through the pass, the automatic door automatically opens the pass, so that the passer can pass through the pass smoothly.

  Patent document 1 proposes controlling an automatic door using two types of sensors. One sensor functions as an activation sensor that detects the contact of a passerby and activates the drive unit of the automatic door. The other sensor functions as a safety sensor that prevents the closing operation of the automatic door that closes the passage if the passer in front of the automatic door is optically detected after the drive unit is activated. According to Patent Document 1, unless the passer touches the sensor, the automatic door maintains a state where the pass door is closed. Thus, the automatic door does not react to a person passing in front of the automatic door. As a result, the automatic door does not unnecessarily open the entrance.

JP 2002-285755 A

  The control technique of Patent Document 1 is very vulnerable to a malfunction of the activation sensor. If a malfunction occurs in the activation sensor, the automatic door cannot open the doorway. If a malfunction occurs in the activation sensor of the automatic door provided in a room having only one entrance, a person existing in the room is confined in the room. In this way, the malfunction that occurs in the activation sensor results in the loss of the essential function of the automatic door.

  An object of the present invention is to provide a control device that can maintain an essential function of an automatic door even if a malfunction occurs in some of a plurality of detection elements used for detection of a passerby. To do.

  A control device according to one aspect of the present invention performs opening control for opening an automatic door. The control device includes a first detection unit and a second detection unit arranged to detect a passerby who passes the automatic door, a defect detection unit that detects a detection defect by the first detection unit, and the defect A switching unit that switches a detection mode from a first detection mode that uses the first detection unit to a second detection mode that uses the second detection unit based on the detection of the malfunction by the detection unit; .

  According to the above configuration, in a normal state (that is, in a state where no malfunction occurs), when the automatic door is completely closed, the signal from the first detection unit is treated as valid. The signal from the second detection unit is treated as invalid. When the defect detection unit detects that a defect has occurred in the detection of the passerby by the first detection unit, the switching unit detects from the first detection mode that uses the first detection unit to detect the passer-by to the second detection unit. Since the detection mode is switched to the second detection mode using, the essential function of the automatic door that performs the opening operation in accordance with the presence of the passerby is appropriately maintained. The term “problem” means a decrease in the detection function of the first detection unit (a decrease in the supply voltage to the first detection unit due to insufficient battery power or other causes, It may mean a decrease in signal intensity due to deterioration, poor communication due to disturbance noise, or contamination of the optical element of the first detection unit. In addition, the term “problem” means a deterioration in the detection function of the first detection unit or a failure of the first detection unit caused by mischief to the first detection unit or other inappropriate operation. May be.

  In the above configuration, the automatic door includes a door body that is displaced between an open position that opens a passage through which the passer-by passes and a closed position that closes the passage opening, and a drive unit that drives the door body, May be included. The first detection unit may function as a first activation sensor that activates the driving unit and generates a first activation signal for displacing the door body from the closed position to the open position. When the malfunction detection unit detects the malfunction, the second detection unit activates the drive unit and generates a second activation signal for displacing the door body from the closed position to the open position. You may function as 2 starting sensors.

  According to the above configuration, when the failure detection unit detects that a failure has occurred in detection of a passerby by the first detection unit, the second detection unit activates the drive unit and opens the door body from the closed position to the open position. Since it functions as the 2nd starting sensor which generates the 2nd starting signal for displacing to, the essential function of the automatic door which opens according to the existence of a passerby is maintained appropriately.

  In the above configuration, when the second detection unit detects the passerby when the door body is displaced toward the closed position, the second detection unit directs the door body to the open position. It may function as a safety sensor that generates a request signal for requesting displacement.

  According to the above configuration, when the second detection unit detects a passerby when the door body is displaced toward the closed position, the second detection unit displaces the door body toward the open position. Acting as a safety sensor that generates the required request signal, the passer can safely pass through the automatic door.

  In the above configuration, the first detection unit may be a mechanical sensor that generates the first activation signal in response to contact of the passerby. The second detection unit may be an optical sensor that generates the second activation signal in response to interruption of an optical path by the passerby.

  According to the above configuration, the automatic door can open the passage according to the passer's contact with the mechanical sensor under the first detection mode. In the second detection mode, the automatic door can open the passage according to the passage of the light path by the passerby. Therefore, the essential function of the automatic door that opens according to the presence of a passerby is appropriately maintained.

  In the above configuration, the first detection unit may be a first optical sensor that defines a first optical path. The second detection unit may be a second optical sensor that defines a second optical path different from the first optical path. When the passerby blocks the first optical path, the first detection unit may generate the first activation signal. When the passerby blocks the second optical path, the second detection unit may generate the second activation signal.

  According to the above configuration, the automatic door can open the passage according to the passage of the first optical path by the passer-by in the first detection mode. Under the second detection mode, the automatic door can open the passage according to the passage of the second optical path by the passerby.

  In the above configuration, the first optical sensor may have an optical axis defined along the first optical path. When the optical axis disappears, the defect detection unit may notify the switching unit of the occurrence of the defect.

  According to the above configuration, when the first optical sensor has a problem of losing the optical axis, the control device can detect a passerby and cause the automatic door to open the entrance in the second detection mode. it can.

  In the above configuration, the first detection unit may include a signal output unit that outputs the first activation signal. When the signal strength of the first activation signal falls below an intensity threshold, the failure detection unit may notify the switching unit of the occurrence of the failure.

  According to the above configuration, when the signal strength of the first activation signal falls below the strength threshold, the failure detection unit notifies the switching unit of the occurrence of the failure, so even when the signal strength of the first activation signal is insufficient. The automatic door can open the entrance in response to the second activation signal. Therefore, the essential function of the automatic door that opens according to the presence of a passerby is appropriately maintained.

  In the above configuration, the first detection unit may include a battery that supplies power to the signal output unit. When the battery remaining amount of the battery falls below a remaining amount threshold value, the defect detection unit may notify the switching unit of the occurrence of the defect.

  According to the above configuration, when the battery remaining amount falls below the remaining amount threshold value, the first detection unit notifies the switching unit of the occurrence of the failure, so even when the remaining battery level is insufficient, The door can open the entrance in response to the second activation signal. Therefore, the essential function of the automatic door that opens according to the presence of a passerby is appropriately maintained.

  The said structure WHEREIN: A said 2nd detection part may be arrange | positioned so that the said passer-by may be detected simultaneously with a said 1st detection part. The malfunction detection unit determines that the malfunction has occurred in the first detection unit when the second activation signal is output from the second detection unit in the absence of the output of the first activation signal. May be.

  According to the above configuration, the failure detection unit determines that a failure has occurred in the first detection unit when the second activation signal is output from the second detection unit in the absence of the output of the first activation signal. Therefore, the control device can switch the detection mode from the first detection mode to the second detection mode in response to various problems occurring in the first detection unit.

  The above-described control device makes it possible to maintain the essential function of the automatic door even if a malfunction occurs in a part of the plurality of detection elements used for detecting a passerby.

<First Embodiment>
The present inventors have developed a technique for maintaining the essential function of an automatic door that opens a passage according to the presence of a human even if some trouble occurs in some detection elements. In the first embodiment, a technical concept for maintaining the essential function of the automatic door is described.

  FIG. 1 is a conceptual diagram of a control device 100 according to the first embodiment. The control apparatus 100 is demonstrated with reference to FIG.

  The control device 100 executes an opening operation for opening the automatic door AMD. The control device 100 may additionally execute a closing operation for closing the automatic door AMD. Alternatively, the closing operation of the automatic door AMD may be controlled by other control structures. The principle of this embodiment is not limited at all depending on whether or not the control device 100 performs control related to the closing operation of the automatic door AMD.

  The control device 100 includes a first detection unit 200, a second detection unit 300, a defect detection unit 400, and a switching unit 500. The first detection unit 200 and the second detection unit 300 are arranged to detect a passerby PSR that passes through the automatic door AMD. When the passer-by PSR exists before the automatic door AMD, the first detection unit 200 generates a first detection signal indicating the presence of the passer-by PSR. The first detection signal is transmitted from the first detection unit 200 to the defect detection unit 400. Signal transmission from the first detection unit 200 to the failure detection unit 400 may be wireless or wired. The principle of this embodiment is not limited to a specific transmission method of the first detection signal.

  The defect detection unit 400 may detect a defect that has occurred in the first detection unit 200 using various methods. For example, the failure detection unit 400 may determine whether or not a failure has occurred in the first detection unit 200 with reference to information represented by the first detection signal. The first detection signal indicates not only the presence of the passer PSR in front of the automatic door AMD but also the remaining battery power (hereinafter referred to as “battery remaining amount”) incorporated in the first detection unit 200. The failure detection unit 400 may determine whether or not the first detection unit 200 has sufficient power to appropriately operate with reference to the information on the remaining battery level. If the first detection signal represents an insufficient remaining battery level, the malfunction detection unit 400 may generate malfunction information representing the malfunction of the first detection unit 200. Alternatively or additionally, the failure detection unit 400 may determine whether or not a failure has occurred in the first detection unit 200 by referring to the quality of the first detection signal. For example, if the signal strength of the first detection signal is excessively low, the malfunction detection unit 400 may generate malfunction information that represents the malfunction of the first detection unit 200.

  The defect detection unit 400 may determine whether the battery remaining amount is insufficient or the signal strength is insufficient by using an appropriately set threshold value. If the remaining amount threshold is set to an appropriate value with respect to the remaining battery level, the defect detection unit 400 can generate defect information before the first detection unit 200 stops functioning completely. . If the intensity threshold is set to an appropriate value with respect to the signal intensity of the first detection signal, the failure detection is performed before the communication between the first detection unit 200 and the failure detection unit 400 is completely cut off. The unit 400 can generate defect information. Therefore, the term “problem of the first detection unit 200” means not only a problem that actually occurs in the first detection unit 200 but also a problem that is likely to occur in the first detection unit 200.

  The defect information is output from the defect detection unit 400 to the switching unit 500. The defect information may include only information indicating that a defect has occurred in the first detection unit 200. Alternatively, the defect information may represent the content of a defect that has occurred in the first detection unit 200. For example, if the malfunction detection unit 400 detects that the battery level of the first detection unit 200 is insufficient, the malfunction information may indicate that the battery level of the first detection unit 200 is insufficient. If the failure detection unit 400 detects a lack of signal strength of the first detection signal, the failure information may represent a lack of signal strength of the first detection signal. The principle of this embodiment is not limited to the specific content represented by the defect information.

  The term “failure” may represent various states that can affect the normal operation of the automatic door AMD, as well as insufficient battery power and signal strength. For example, the term “failure” may mean a communication failure of the first detection signal due to disturbance noise. Alternatively, if the first detection unit 200 is formed using an optical element such as a lens, a light-emitting element, or a light-receiving element, the term “defect” refers to contamination of some or all of these optical components. It may mean a malfunction caused by the problem. Further alternatively, the term “failure” may mean a failure of the first detection unit 200 caused by mischief or other inappropriate operation. The principle of this embodiment is not limited to a specific definition for the term “problem”. However, the above definitions may be applied to various embodiments described below.

  If the defect information represents the content of the defect that has occurred in the first detection unit 200, the defect information may be recorded in a storage medium (not shown). The worker can repair the first detection unit 200 appropriately and efficiently by referring to the defect information stored in the storage medium.

  Before the defect information is transmitted from the defect detection unit 400 to the switching unit 500 (that is, while the automatic door AMD is operating normally), the first detection signal is transmitted through the defect detection unit 400. 200 to the switching unit 500. At this time, the first detection signal is handled as a valid signal for starting the automatic door AMD, while the second detection signal is not handled as a valid signal for starting the automatic door AMD. The switching unit 500 generates an opening control signal for executing the opening control of the automatic door AMD according to the first detection signal. The opening control signal is output from the switching unit 500 to the automatic door AMD. The automatic door AMD opens in response to the opening control signal.

  When the defect information is transmitted from the defect detection unit 400 to the switching unit 500, the switching unit 500 starts from the first detection mode in which the first detection unit 200 is used to detect the passerby PSR according to the defect information. It switches to the 2nd detection mode which uses the 2nd detection part 300 for the detection of PSR. Similarly to the first detection unit 200, the second detection unit 300 is arranged to detect the passerby PSR in front of the automatic door AMD, so that the passerby PSR exists in front of the automatic door AMD. The second detection unit 300 generates a second detection signal indicating the presence of a passerby PSR in front of the automatic door AMD. The second detection signal is output from the second detection unit 300 to the switching unit 500. The switching unit 500 generates an open control signal according to the second detection signal. The opening control signal is output from the switching unit 500 to the automatic door AMD. The automatic door AMD opens in response to the opening control signal.

  The switching unit 500 may activate the second detection unit 300 in response to receiving the defect information. Alternatively, even before the first detection unit 200 fails, the second detection unit 300 is activated and generates a second detection signal according to the presence of the passerby PSR in front of the automatic door AMD. Also good. The principle of the present embodiment is not limited to the specific activation timing of the second detection unit 300.

  Detection of passerby PSR may depend on various known detection techniques. For example, the first detection unit 200 may have a function of a contact sensor that detects contact of a passerby PSR. Alternatively, the first detection unit 200 may be an optical sensor (a reflection type sensor and / or a transmission type sensor) or a capacitance sensor that detects blocking of an optical path by a passerby PSR. The second detection unit 300 may be an optical sensor (a reflection type sensor and / or a transmission type sensor) that detects blocking of an optical path by a passerby PSR. Alternatively, the second detection unit 300 may be a camera sensor that determines the presence of the passerby PSR based on the acquired image. The principle of the present embodiment is not limited to a specific detection element used for the first detection unit 200 and the second detection unit 300.

Second Embodiment
The failure detection unit described in relation to the first embodiment refers to the first detection signal and determines whether or not a failure has occurred in the first detection unit. Alternatively, the defect detection unit may use not only the first detection signal but also the second detection signal for determining the defect of the first detection unit. In 2nd Embodiment, the control apparatus which detects the malfunction which arose in the 1st detection part using the 1st detection signal and the 2nd detection signal is demonstrated.

  FIG. 2 is a conceptual diagram of a control device 100A according to the second embodiment. The control device 100A will be described with reference to FIG. The same code | symbol is attached | subjected with respect to the element which is functionally common in 1st Embodiment. The description of the first embodiment is applied to elements having the same reference numerals.

  Similarly to the first embodiment, the control device 100A includes a first detection unit 200 and a switching unit 500. The description of the first embodiment is incorporated in these elements.

  The control device 100A further includes a second detection unit 300A and a defect detection unit 400A. Similar to the first detection unit 200, the second detection unit 300A detects the presence of a passerby PSR in front of the automatic door AMD. If the passer-by PSR exists before the automatic door AMD, the second detection unit 300A generates a second detection signal indicating the presence of the passer-by PSR before the automatic door AMD. The second detection signal is output from the second detection unit 300A to the defect detection unit 400A.

  The detection of the passerby PSR by the second detection unit 300A is performed simultaneously with the detection of the passerby PSR by the first detection unit 200. Therefore, if the first detection unit 200 is functioning normally, the malfunction detection unit 400A receives the first detection signal and the second detection signal. In this case, the malfunction detection unit 400A preferentially outputs the first detection signal to the switching unit 500. The switching unit 500 generates an open control signal according to the first detection signal.

  If a failure occurs in the first detection unit 200, the failure detection unit 400A receives only the second detection signal. If there is reception of the second detection signal in the absence of reception of the first detection signal, the failure detection unit 400A determines that a failure has occurred in the first detection unit 200. In this case, the malfunction detection unit 400A outputs the second detection signal to the switching unit 500. The switching unit 500 generates an open control signal according to the second detection signal.

  Alternatively, the malfunction detection unit 400A may compare the signal strength between the first detection signal and the second detection signal. If the signal strength of the first detection signal is significantly lower than the signal strength of the second detection signal, the failure detection unit 400A may determine that a failure has occurred in the first detection unit 200. Also in this case, the malfunction detection unit 400A outputs the second detection signal to the switching unit 500. The switching unit 500 generates an open control signal according to the second detection signal.

  According to the control technique described above, the second detection signal is used as a reference signal for detecting a malfunction of the first detection unit 200 while the first detection unit 200 is operating normally. If a malfunction occurs in the first detection unit 200, the second detection signal is used to detect a passerby PSR in front of the automatic door AMD.

  The principle of this embodiment does not necessarily require analysis of the first detection signal. If a failure occurs in the first detection unit 200, the detection mode is switched from the first detection mode to the second detection mode regardless of the content of the failure and the cause of the failure. In addition, the control device 100 </ b> A does not automatically detect the contamination of the optical element used as the first detection unit 200, the malfunction due to inappropriate operation on the first detection unit 200 or component deterioration of the first detection unit 200. The door AMD can be appropriately controlled.

<Third Embodiment>
The designer can design various control devices based on the design principle described in relation to the first embodiment. In the third embodiment, an exemplary control device is described.

  FIG. 3 is a schematic block diagram of a control device 100B of the third embodiment. The control device 100B will be described with reference to FIGS. The same code | symbol is attached | subjected with respect to the element which is functionally common in 1st Embodiment. The description of the first embodiment is applied to elements having the same reference numerals.

  The control device 100B executes opening control for opening the automatic door AMD. The automatic door AMD includes a drive unit DRV and a door body DOR. The drive unit DRV receives a drive signal from the control device 100B. The drive unit DRV displaces the door body DOR to an open position that opens the passage PSG (see FIG. 1) in accordance with the drive signal. The drive signal transmitted from the control device 100B to the drive unit DRV corresponds to the open control signal described with reference to FIG.

  The driving unit DRV may include a motor and other devices that generate driving force for driving the door DOR. The drive unit DRV may include various mechanisms (for example, a combination of a pulley and a belt) for transmitting the drive force to the door body DOR. The principle of this embodiment is not limited to a specific structure of the drive unit DRV.

  The door body DOR may be displaced slidably or rotated by a driving force. The principle of the present embodiment is not limited to a specific operation of the door body DOR for opening the access port PSG.

  The control device 100B includes a first activation sensor 200B, a second activation sensor 300B, a malfunction detection unit 400B, and a switching unit 500B. The first activation sensor 200B corresponds to the first detection unit 200 described with reference to FIG. The second activation sensor 300B corresponds to the second detection unit 300 described with reference to FIG. The defect detection unit 400B corresponds to the defect detection unit 400 described with reference to FIG. The switching unit 500B corresponds to the switching unit 500 described with reference to FIG.

  If there is no malfunction in first activation sensor 200B, control device 100B generates a drive signal under the first detection mode. Under the first detection mode, the first activation sensor 200B is used to detect a passerby PSR (see FIG. 1) in front of the automatic door AMD. If a malfunction occurs in first activation sensor 200B, control device 100B generates a drive signal under the second detection mode. Under the second detection mode, the second activation sensor 300B is used to detect the passerby PSR in front of the automatic door AMD.

  The first activation sensor 200B is communicably connected to the defect detection unit 400B and the switching unit 500B. The connection between the first activation sensor 200B and the malfunction detection unit 400B and the connection between the first activation sensor 200B and the switching unit 500B may be wireless or wired. The principle of this embodiment is not limited to a specific system related to these connections.

  If the first activation sensor 200B detects the passerby PSR in front of the automatic door AMD while the control device 100B is operating in the first detection mode, the first activation sensor 200B generates a first activation signal. Generate. The first activation signal is output to the defect detection unit 400B and the switching unit 500B. The defect detection unit 400B refers to the first activation signal and determines whether or not a defect has occurred in the first activation sensor 200B. If the malfunction detection unit 400B does not find a malfunction that has occurred in the first activation sensor 200B, the switching unit 500B converts the first activation signal into a drive signal under the first detection mode. Therefore, the first activation signal is used to drive the drive unit DRV and displace the door body DOR from the closed position that closes the passage port PSG to the open position that opens the passage port PSG under the first detection mode.

  When the malfunction detection unit 400B finds a malfunction that has occurred in the first activation sensor 200B from the first activation signal, the malfunction detection unit 400B outputs malfunction information to the switching unit 500B. As a result, the detection mode of the control device 100B is switched from the first detection mode to the second detection mode. When the second activation sensor 300B detects the passerby PSR in front of the automatic door AMD while the control device 100B is operating in the second detection mode, the second activation sensor 300B generates a second activation signal. Generate. The second activation signal is output from the second activation sensor 300B to the switching unit 500B. The switching unit 500B converts the second activation signal into a drive signal under the second detection mode. Therefore, the second activation signal is used to drive the drive unit DRV and to displace the door body DOR from the closed position that closes the passage port PSG to the open position that opens the passage port PSG in the second detection mode.

  Switching unit 500B includes a mode determination unit 510, a signal selection unit 520, and a drive signal generation unit 530. The initial setting of the control device 100B or the setting immediately after the repair of the first activation sensor 200B specifies that the control device 100B operates in the first detection mode. Thereafter, when the mode determination unit 510 receives the defect information from the defect detection unit 400B, the mode determination unit 510 generates a switching request signal according to the defect information. The switching request signal is output from mode determination unit 510 to signal selection unit 520.

  The signal selection unit 520 selects one of the first activation signal and the second activation signal as an output signal output to the drive signal generation unit 530. Before the signal selection unit 520 receives the switching request signal, the signal selection unit 520 selects the first activation signal as the output signal. Accordingly, the first activation signal is output from the signal selection unit 520 to the drive signal generation unit 530. The drive signal generation unit 530 generates a drive signal according to the first activation signal. The drive signal is output from the drive signal generation unit 530 to the drive unit DRV. The drive unit DRV drives the door body DOR according to the drive signal. Accordingly, the automatic door AMD is activated by the first activation signal. During this time, the second activation signal is ignored.

  When the signal selection unit 520 receives the switching request signal, the signal selection unit 520 selects the second activation signal as the output signal. Therefore, the second activation signal is output from the signal selection unit 520 to the drive signal generation unit 530. The drive signal generation unit 530 generates a drive signal according to the second activation signal. The drive signal is output from the drive signal generation unit 530 to the drive unit DRV. The drive unit DRV drives the door body DOR according to the drive signal. Accordingly, the automatic door AMD is activated by the second activation signal. During this time, the first activation signal is ignored.

<Fourth embodiment>
When the passer is passing the entrance, if the door attempts to close the pass, the door may collide with the passer. The control device may execute safety control for preventing a collision between the door body and the passerby. In the fourth embodiment, an exemplary control device that executes safety control will be described.

  FIG. 4 is a schematic block diagram of a control device 100C according to the fourth embodiment. The control device 100C will be described with reference to FIGS. The same code | symbol is attached | subjected with respect to the element which is functionally common in 3rd Embodiment. The description of the third embodiment is applied to elements having the same reference numerals.

  Similar to the third embodiment, the control device 100C includes a first activation sensor 200B and a malfunction detection unit 400B. The description of the third embodiment is incorporated in these elements.

  The control device 100C further includes a safety sensor 300C and a switching unit 500C. The safety sensor 300C corresponds to the second detection unit 300 described with reference to FIG. The switching unit 500C corresponds to the switching unit 500 described with reference to FIG.

  Similar to the third embodiment, the switching unit 500C includes a mode determination unit 510 and a signal selection unit 520. The description of the third embodiment is incorporated in these elements.

  The safety sensor 300C defines a detection area near the traffic port PSG (see FIG. 1). If the passerby PSR (see FIG. 1) is present in the detection area, the safety sensor 300C generates a detection signal. The detection signal is output from the safety sensor 300C to the signal selection unit 520. The detection signal output from the safety sensor 300C to the signal selection unit 520 corresponds to the second activation signal described in relation to the third embodiment. Therefore, the signal selection unit 520 that has received the switching request signal from the mode determination unit 510 outputs the detection signal from the safety sensor 300C as an output signal.

  Switching unit 500C further includes a drive signal generation unit 530C. Drive signal generation unit 530 </ b> C includes an open signal generation unit 531, a closed signal generation unit 532, and a timer 533. Under the first detection mode, the first activation signal is output from the signal selection unit 520 to the open signal generation unit 531 as an output signal. Under the second detection mode, the detection signal is output from the signal selection unit 520 to the open signal generation unit 531 as an output signal. The open signal generator 531 generates an open signal according to the first activation signal or the detection signal. The open signal is output from the open signal generation unit 531 to the drive unit DRV. The drive unit DRV displaces the door body DOR from the closed position to the open position in response to the open signal. Therefore, the control device 100C can activate the automatic door AMD based on the same control principle as in the third embodiment.

  After the automatic door AMD is activated, the safety sensor 300C is used to prevent the door body DOR from being displaced from the open position to the closed position while the passer-by PSR is passing through the passport PSG. For this reason, the detection signal generated by the safety sensor 300C is output not only to the signal selection unit 520 but also to the timer 533. The timer 533 sets the time measurement value to “0” according to the detection signal.

  While the passer-by PSR exists in the detection area, the safety sensor 300C continues to output the detection signal. Therefore, until the passerby PSR leaves the detection area, the timer 533 maintains the time measurement value at “0”. The timer 533 starts timing (that is, increases the timing value) when no detection signal is received.

  The closed signal generation unit 532 refers to the time value of the timer 533. If the measured value exceeds the timer threshold value (> 0), the closed signal generation unit 532 generates a closed signal. The closing signal is output from the closing signal generation unit 532 to the driving unit DRV. The drive unit DRV displaces the door body DOR from the open position to the closed position in response to the close signal.

  The open signal generation unit 531 refers to the time value of the timer 533 after receiving the output signal. If the timed value is equal to or less than the timer threshold value and the door DOR has not reached the open position, the open signal generation unit 531 generates an open signal. If the time measured value is equal to or less than the timer threshold value and the door body DOR has reached the open position, the door body DOR is maintained in the open position. If the passerby PSR away from the detection area defined by the safety sensor 300C returns to the detection area after the door body DOR starts to move from the open position to the closed position, the time value of the timer 533 is the safety value. It becomes “0” by the detection signal from the sensor 300C. Therefore, at this time, the drive unit DRV receives the open signal instead of the close signal. As a result, the drive unit DRV displaces the door body DOR toward the open position. In the present embodiment, the request signal is exemplified by a detection signal output from the safety sensor 300C to the timer 533.

  Similarly, if another passerby (not shown) tries to pass the passway PSG after the door body DOR starts to be displaced from the open position to the closed position, the safety sensor 300C will detect the passerby. The detection signal is output to the timer 533. As a result, the time value of the timer 533 becomes “0”. Therefore, at this time, the drive unit DRV receives the open signal instead of the close signal. As a result, the drive unit DRV displaces the door body DOR toward the open position.

<Fifth Embodiment>
The designer can design various control devices based on the design principle described in relation to the fourth embodiment. In the fifth embodiment, an exemplary control device is described.

  FIG. 5 is a schematic diagram of a control device 100D of the fifth embodiment. The control device 100D will be described with reference to FIGS.

  The control device 100D includes a touch switch 200D, an eyeless sensor 300D, and a control panel 600. The drive unit DRV is disposed in the seamless TSM. The door body DOR is disposed below the seamless TSM.

  The touch switch 200D is attached to the front surface of the door body DOR. The touch switch 200D is a mechanical sensor that generates a first activation signal in response to contact of a passerby (not shown). The touch switch 200D corresponds to the first activation sensor 200B described with reference to FIG. Various structures of known touch switches may be applied to the touch switch 200D. Therefore, the principle of the present embodiment is not limited to the specific structure of the touch switch 200D.

  The blind sensor 300D is attached to the blind TSM. The invisible sensor 300D is an optical sensor including a plurality of light emitting elements (not shown) and a plurality of light receiving elements (not shown). The eyeless sensor 300D emits detection light from a plurality of light emitting elements, and defines a detection region in front of the door body DOR. When the passerby enters the detection area, a part of the plurality of light receiving elements receives the reflected light from the detection area changed by the passerby or the like. As a result, the eyeless sensor 300D generates a detection signal. The invisible sensor 300D corresponds to the safety sensor 300C described with reference to FIG. Various techniques of known blind sensors may be applied to blind sensor 300D. For example, the eyeless sensor 300D may determine the traveling direction of the passerby from detection areas defined using a plurality of spot areas. In this case, the blind sensor 300D may generate the detection signal only when the passerby moves toward the door DOR. As a result, the eyeless sensor 300D can prevent an unnecessary opening / closing operation of the door DOR even when it is placed when a problem occurs in the touch switch 200D. The principle of the present embodiment is not limited to a specific structure of the invisible sensor 300D or a specific passer-by detection technique by the invisible sensor 300D.

  The control panel 600 is wirelessly connected to the touch switch 200D. The control panel 600 is connected to the eyeless sensor 300D in a wired manner. The control panel 600 controls the drive unit DRV according to the first activation signal from the touch switch 200D and the detection signal from the eyeless sensor 300D. The control of the drive unit DRV by the control panel 600 is based on the control principle described in relation to the fourth embodiment. In addition, the control panel 600 may control the light emission pattern of the eyeless sensor 300D.

  The control panel 600 may include a receiving element (not shown) that receives the first activation signal from the touch switch 200D. In addition, the control panel 600 may include a CPU (Central Processing Unit: not shown) and other arithmetic elements (not shown). The control panel 600 may further include a signal generation circuit (not shown).

  The CPU of the control panel 600 may execute a program that compares the signal strength of the first activation signal received from the touch switch 200D with the strength threshold value. The CPU may execute a program that selects one of the first activation signal and the detection signal based on a comparison result between the intensity threshold and the signal intensity of the first activation signal. The CPU may execute a timer program that starts timing in response to a change in the reception mode of the detection signal from reception to non-reception.

  The signal generation circuit of the control panel 600 may generate an open signal in response to the first activation signal or the detection signal. In addition, the signal generation circuit may generate a closed signal according to the result obtained from the execution of the timer program.

  FIG. 6 is a schematic flowchart showing processing executed by the control panel 600 under the first detection mode. With reference to FIGS. 5 and 6, the processing of the control panel 600 will be described.

(Step S105)
The control panel 600 (see FIG. 5) waits for a first activation signal from the touch switch 200D (see FIG. 5). During this time, the door body DOR (see FIG. 5) is in the closed position. When the control panel 600 receives the first activation signal, step S110 is executed.

(Step S110)
The control panel 600 compares the signal strength of the first activation signal with the strength threshold value. If the signal strength is greater than the strength threshold, step S115 is executed. In other cases, step S155 is executed.

(Step S115)
The control panel 600 generates an open signal. The open signal is output from the control panel 600 to the drive unit DRV (see FIG. 5). The drive unit DRV displaces the door body DOR from the closed position to the open position in response to the open signal. When the control panel 600 generates an open signal, step S120 is executed.

(Step S120)
The control panel 600 determines whether a detection signal is received from the eyeless sensor 300D. While the control panel 600 receives the detection signal, step S120 is continuously executed. When no detection signal is received, step S125 is executed.

(Step S125)
Control panel 600 starts timing. Thereafter, step S130 is executed.

(Step S130)
The control panel 600 compares the measured time value with a timer threshold value. If the timed value is greater than the timer threshold value, step S135 is executed. In other cases, step S150 is executed.

(Step S135)
The control panel 600 generates a close signal. The closing signal is output from the control panel 600 to the drive unit DRV. The drive unit DRV displaces the door body DOR toward the closed position in response to the close signal. When the control panel 600 generates a close signal, step S140 is executed.

(Step S140)
The control panel 600 determines whether a detection signal is received from the eyeless sensor 300D. If control panel 600 has received the detection signal, step S115 is executed. In other cases, step S145 is executed.

(Step S145)
The control panel 600 determines whether or not the door DOR has reached the closed position. For this determination, a position sensor that detects the position of the door body DOR, a total rotation amount of a motor used in the drive unit DRV, or other factors may be used. The principle of this embodiment is not limited to a specific method for determining whether the door DOR has reached the closed position.

(Step S150)
The control panel 600 determines whether a detection signal is received from the eyeless sensor 300D. If control panel 600 has received the detection signal, step S115 is executed. In other cases, step S130 is executed.

(Step S155)
The control panel 600 switches the detection mode from the first detection mode to the second detection mode. Thereafter, step S160 is executed.

(Step S160)
The control panel 600 determines whether a detection signal is received from the eyeless sensor 300D. If control panel 600 has received the detection signal, step S115 is executed. In other cases, step S165 is executed.

(Step S165)
The fact that the control panel 600 does not receive the detection signal at substantially the same time as the time when the first activation signal is received indicates that the touch switch 200D (see FIG. 5) detects the passerby while the blind sensor 300D. Means that no passers are detected. This means that some abnormality has occurred in the detection system for detecting a passerby. Therefore, the control panel 600 executes predetermined error processing. For example, the control panel 600 may process the first activation signal received in step S105 as an error signal.

  FIG. 7 is a schematic flowchart showing processing executed by the control panel 600 under the second detection mode. The processing of the control panel 600 will be described with reference to FIGS.

(Step S106)
The control panel 600 (see FIG. 5) waits for a detection signal from the blind sensor 300D (see FIG. 5). During this time, the door body DOR (see FIG. 5) is in the closed position. When control panel 600 receives the detection signal, step S115 is executed.

  The processing from step S115 to step S150 is common to the processing under the first detection mode (see FIG. 6).

<Sixth Embodiment>
The control device described in relation to the fifth embodiment detects that the signal intensity of the first activation signal from the touch switch is equal to or less than the intensity threshold value as a malfunction. Additionally or alternatively, the control device may detect that the remaining power level of the battery incorporated in the touch switch is equal to or less than the remaining threshold value as a problem. In the sixth embodiment, an exemplary control device that switches the detection mode according to the detected remaining battery level will be described.

  FIG. 8 is a schematic block diagram of a control device 100E according to the sixth embodiment. The control device 100E is described with reference to FIGS. 5 and 6 to 8. The same code | symbol is attached | subjected with respect to the element which is functionally common with 4th Embodiment. The description of the fourth embodiment is applied to elements having the same reference numerals.

  Control device 100E includes a touch switch 200E, an eyeless sensor 300E, and a control panel 600E. The touch switch 200E corresponds to the touch switch 200D described with reference to FIG. The eyeless sensor 300E corresponds to the eyeless sensor 300D described with reference to FIG. The control panel 600E corresponds to the control panel 600 described with reference to FIG.

  The touch switch 200E includes a battery 210 and an activation signal generation unit 220. The battery 210 supplies power to the activation signal generation unit 220. The activation signal generation unit 220 generates a first activation signal under power supply from the battery 210.

  The activation signal generation unit 220 includes a contact detection unit 221, a remaining amount detection unit 222, a signal generation unit 223, and a transmission unit 224. The contact detection unit 221 detects contact by a passerby (not shown) and generates a contact signal. The contact signal is output from the contact detection unit 221 to the remaining amount detection unit 222 and the signal generation unit 223.

  The remaining amount detection unit 222 detects the remaining battery level in response to receiving the contact signal. The detection of the remaining battery level may be various detection techniques for detecting the power remaining in the battery. The principle of this embodiment is not limited to a specific detection technique for obtaining the remaining battery level.

  The remaining amount detection unit 222 generates remaining amount information indicating the detected remaining battery level. The remaining amount information is output from the remaining amount detection unit 222 to the signal generation unit 223.

  The signal generation unit 223 generates a first activation signal according to the contact signal. At this time, the signal generation unit 223 incorporates the remaining amount information into the first activation signal. Therefore, the first activation signal represents not only that the passerby touched the touch switch 200E but also the remaining battery level. The first activation signal is output from the signal generation unit 223 to the transmission unit 224. The transmission unit 224 transmits the first activation signal as a radio signal to the control panel 600E. The transmission unit 224 may transmit the first activation signal a plurality of times in response to one pass of the passerby to the touch switch 200E. Alternatively, the transmission unit 224 may transmit the first activation signal with another transmission pattern. The principle of the present embodiment is not limited to a specific transmission pattern of the first activation signal. In the present embodiment, the signal output unit is exemplified by the transmission unit 224.

  The control panel 600E includes the switching unit 500C described in relation to the fourth embodiment. The description of the fourth embodiment is incorporated in the switching unit 500C.

  Control panel 600E further includes a receiving unit 610 and a failure detecting unit 400E. The receiving unit 610 receives the first activation signal as a radio signal from the transmitting unit 224 (corresponding to step S105 in FIG. 6). The receiving unit 610 converts the first activation signal from a radio signal to an electrical signal. Thereafter, the first activation signal is output from the reception unit 610 to the defect detection unit 400E and the signal selection unit 520.

  The defect detection unit 400E includes an intensity comparison unit 410 and a remaining amount comparison unit 420. The intensity comparison unit 410 compares the signal intensity of the first activation signal with an intensity threshold (corresponding to step S110 in FIG. 6). If the transmission unit 224 transmits the first activation signal a plurality of times, the intensity comparison unit 410 may count the number of times the first activation signal having a signal intensity lower than the intensity threshold is output. If the count number exceeds a predetermined value, the intensity comparison unit 410 may generate defect information resulting from a decrease in signal intensity. In step S110 described with reference to FIG. 6, the remaining amount comparison unit 420 refers to the first activation signal and reads the remaining amount information incorporated in the first activation signal. If the remaining amount information is below the remaining amount threshold value, the remaining amount comparing unit 420 generates defect information resulting from a shortage of the remaining battery level. The defect information is output from the defect detection unit 400E to the mode determination unit 510.

  When the passerby enters the detection area, the eyeless sensor 300E generates a detection signal. The detection signal is output from the eyeless sensor 300E to the signal selection unit 520 and the timer 533.

  The switching unit 500C performs the processing of steps S115 to S165 described with reference to FIG. 6 under the first detection mode, and generates an open signal and a close signal. The switching unit 500C performs the process described with reference to FIG. 7 under the second detection mode, and generates an open signal and a close signal.

<Seventh embodiment>
The control device may have a plurality of touch switches. In this case, the control device can control an automatic door that opens and closes the passageway by interlocking a plurality of door bodies. In the seventh embodiment, an exemplary control device having a plurality of touch switches is described.

  FIG. 9 is a schematic diagram of a control device 100F of the seventh embodiment. The control device 100F will be described with reference to FIG. The same code | symbol is attached | subjected with respect to the element which is functionally common with 5th Embodiment. The description of the fifth embodiment is applied to elements having the same reference numerals.

  Control device 100F controls automatic door AME provided with left door LDR and right door RDR. Under the control of the control device 100F, the left door LDR is displaced to the left below the invisible TSM and opens a passage (not shown). The left door LDR is displaced to the right below the seamless TSM under the control of the control device 100F, and closes the passageway. The right door RDR is displaced to the right below the seamless TSM under the control of the control device 100F, and opens the passage. The right door RDR is displaced to the left under the silent TSM under the control of the control device 100F, and closes the entrance.

  Similar to the fifth embodiment, the control device 100F includes an eyeless sensor 300D. The invisible sensor 300D irradiates the detection light in front of the left door LDR and the right door RDR to define a detection area. When a passerby (not shown) enters the detection area, the invisible sensor 300D detects the presence of the passerby. The description of the fifth embodiment is applied to the invisible sensor 300D.

  Control device 100F includes a left touch switch 201, a right touch switch 202, and a control panel 600F. The left touch switch 201 is attached to the left door LDR. The right touch switch 202 is attached to the right door RDR. When a passerby contacts one of the left touch switch 201 and the right touch switch 202, the drive unit DRV is activated under the control of the control panel 600F arranged in the invisible TSM. As a result, the left door LDR is displaced leftward and the right door RDR is displaced rightward. Thereafter, the invisible sensor 300D functions as a safety sensor.

  FIG. 10 is a schematic block diagram illustrating an exemplary functional configuration of the control device 100F. The control device 100F will be further described with reference to FIGS. The same code | symbol is attached | subjected with respect to the element which is functionally common with 6th Embodiment. The description of the sixth embodiment is applied to elements having the same reference numerals.

  Similar to the touch switch 200 </ b> E described with reference to FIG. 8, the left touch switch 201 includes a battery 210 and an activation signal generation unit 220. Therefore, similarly to the touch switch 200E, when the contact detection unit 221 detects a passerby's contact, the transmission unit 224 transmits a first activation signal. As described in relation to the sixth embodiment, the first activation signal includes remaining amount information.

  Similar to the touch switch 200 </ b> E described with reference to FIG. 8, the right touch switch 202 includes a battery 210 and an activation signal generation unit 220. Therefore, similarly to the touch switch 200E, when the contact detection unit 221 detects a passerby's contact, the transmission unit 224 transmits a first activation signal. As described in relation to the sixth embodiment, the first activation signal includes remaining amount information.

  Similar to the sixth embodiment, the control panel 600F includes a failure detection unit 400E and a switching unit 500C. The description of the sixth embodiment is incorporated in these elements.

  Control panel 600F further includes a receiving unit 610F. When the passerby touches the left touch switch 201, the receiving unit 610F receives the first activation signal from the left touch switch 201 as a radio signal. When the passerby contacts the right touch switch 202, the receiving unit 610F receives the first activation signal from the right touch switch 202 as a wireless signal. The receiving unit 610F converts the first activation signal from a radio signal to an electrical signal. Thereafter, the reception unit 610F outputs the first activation signal to the defect detection unit 400E and the signal selection unit 520.

  The control panel 600F executes the processing described with reference to FIGS. 6 and 7 and controls the automatic door AME. When the defect detection unit 400E detects at least one defect (for example, a decrease in signal strength or a shortage of remaining battery power) of the left touch switch 201 and the right touch switch 202, the control panel 600F detects the detection mode as the first detection mode. Switch from mode to second detection mode. The second detection mode may be maintained until an operator who repairs the control device 100F solves the problem.

<Eighth Embodiment>
The automatic door partitions the space into two spaces (hereinafter referred to as “front space” and “rear space”). The control device may detect both passers-by from the front space to the back space and passers-by from the back space to the front space. In the eighth embodiment, an exemplary control device capable of detecting a plurality of passersby that are different in the moving direction will be described.

  FIG. 11 is a schematic diagram of a control device 100G of the eighth embodiment. The control device 100G will be described with reference to FIG. The same code | symbol is attached | subjected with respect to the element which is functionally common with 5th Embodiment. The description of the fifth embodiment is applied to elements having the same reference numerals.

  The control device 100G includes a front touch switch 203, a rear touch switch 204, a front blind sensor 301, a rear blind sensor 302, and a control panel 600G. Door body DOR includes a front surface DRF and a rear surface DRR. The front DRF faces the front space. The rear surface DRR opposite to the front surface DRF faces the rear space. The front touch switch 203 is attached to the front surface DRF. The rear touch switch 204 is attached to the rear surface DRR. The eyeless TSM includes a front surface TMF and a rear surface TMR. The front TMF faces the front space. The rear surface TMR opposite to the front surface TMF faces the rear space. The front blind sensor 301 is attached to the front TMF. The rear blind sensor 302 is attached to the rear surface TMR. The control panel 600G and the drive unit DRV are disposed between the front surface TMF and the rear surface TMR.

  A passerby (not shown) moving from the front space toward the rear space touches the front touch switch 203. As a result, the front touch switch 203 communicates with the control panel 600G. Control panel 600G activates drive unit DRV in response to communication with front touch switch 203. As a result, the door body DOR opens a passage (not shown).

  The front seamless sensor 301 and the rear seamless sensor 302 function as safety sensors after the drive unit DRV is activated. The front blind sensor 301 emits detection light in the front space and defines a front detection region. The rear blind sensor 302 emits detection light in the rear space and defines a rear detection region.

  The front blind sensor 301 detects a passerby before a passerby (not shown) moving from the front space toward the rear space passes through a passport (not shown). Therefore, the door body DOR does not close the passage before the passerby passes through the passage. Passers who have passed through the entrance enter the post-detection area. Therefore, the rear blind sensor 302 can detect a passerby. As a result, the door body DOR does not close the passageway until the passerby escapes from the rear detection area.

  Before a passerby (not shown) moving from the rear space toward the front space passes through the passway, the rear blind sensor 302 detects the passerby. Therefore, the door body DOR does not close the passage before the passerby passes through the passage. A passerby who has passed through the entrance enters the pre-detection area. Therefore, the front blind sensor 301 can detect a passerby. As a result, the door DOR does not close the passageway until the passerby escapes from the previous detection area.

  FIG. 12 is a schematic block diagram illustrating an exemplary functional configuration of the control device 100G. The control device 100G will be further described with reference to FIGS. 6 and 10 to 12. The same code | symbol is attached | subjected with respect to the element which is functionally common with 7th Embodiment. The description of the seventh embodiment is applied to elements having the same reference numerals.

  Similar to the left touch switch 201 described with reference to FIG. 10, the front touch switch 203 includes a battery 210. The front touch switch 203 generates an activation signal FAS under power supply from the battery 210. The description of the seventh embodiment is applied to the battery 210.

  The front touch switch 203 further includes an activation signal generation unit 230. Similar to the activation signal generation unit 220 described with reference to FIG. 10, the activation signal generation unit 230 includes a contact detection unit 221 and a remaining amount detection unit 222. The description of the seventh embodiment is incorporated in these elements.

  The activation signal generation unit 230 further includes a signal generation unit 233 and a transmission unit 234. When the contact detection unit 221 detects the contact of a passerby moving from the front space to the rear space, the signal generation unit 233 generates an activation signal FAS. Similar to the signal generation unit 223 described with reference to FIG. 10, the signal generation unit 233 acquires the remaining amount information from the remaining amount detection unit 222. The signal generation unit 233 incorporates the remaining amount information into the activation signal FAS. Therefore, the activation signal FAS includes remaining amount information. The signal generator 233 gives unique identification information to the activation signal FAS. As a result, it is determined that the activation signal FAS is a signal output from the front touch switch 203. Activation signal FAS is transmitted to control panel 600G by transmission unit 234.

  Similar to the right touch switch 202 described with reference to FIG. 10, the rear touch switch 204 includes a battery 210. The rear touch switch 204 generates an activation signal RAS under power supply from the battery 210. The description of the seventh embodiment is applied to the battery 210.

  The rear touch switch 204 further includes an activation signal generation unit 240. Similar to the activation signal generation unit 220 described with reference to FIG. 10, the activation signal generation unit 240 includes a contact detection unit 221 and a remaining amount detection unit 222. The description of the seventh embodiment is incorporated in these elements.

  Activation signal generation unit 240 further includes a signal generation unit 243 and a transmission unit 244. When the contact detection unit 221 detects the contact of a passerby moving from the rear space to the front space, the signal generation unit 243 generates an activation signal RAS. Similar to the signal generation unit 223 described with reference to FIG. 10, the signal generation unit 243 acquires the remaining amount information from the remaining amount detection unit 222. The signal generation unit 243 incorporates the remaining amount information into the activation signal RAS. Therefore, the activation signal RAS includes remaining amount information. The signal generation unit 243 gives unique identification information to the activation signal RAS. As a result, it is determined that the activation signal RAS is a signal output from the rear touch switch 204. Activation signal RAS is transmitted to control panel 600G by transmission unit 244.

  Control panel 600G includes a defect detection unit 400G, a switching unit 500G, and a reception unit 610G. When the passerby touches the front touch switch 203, the reception unit 610G receives the activation signal FAS from the transmission unit 234 as a radio signal. The receiving unit 610G converts the activation signal FAS from a radio signal to an electrical signal. Thereafter, the reception unit 610G outputs the activation signal FAS to the defect detection unit 400G and the switching unit 500G. When the passerby touches the rear touch switch 204, the reception unit 610G receives the activation signal RAS as a radio signal from the transmission unit 244. The receiving unit 610G converts the activation signal RAS from a radio signal to an electrical signal. Thereafter, the reception unit 610G outputs the activation signal RAS to the failure detection unit 400G and the switching unit 500G.

  Similar to the seventh embodiment, the defect detection unit 400G includes an intensity comparison unit 410 and a remaining amount comparison unit 420. The description of the seventh embodiment is incorporated in these elements.

  The defect detection unit 400G further includes a signal identification unit 430.

If the signal received from the reception unit 610G includes the identification information provided by the signal generation unit 233 of the front touch switch 203, the signal identification unit 430 identifies that the target of failure analysis is the activation signal FAS. If the signal received from the reception unit 610G includes the identification information provided by the signal generation unit 243 of the rear touch switch 204, the signal identification unit 430 identifies that the target of the failure analysis is the activation signal RAS.

  Switching unit 500G includes a mode determination unit 510G, a signal selection unit 520G, and a drive signal generation unit 530G. If the failure information indicates that a failure has occurred in the front touch switch 203, the mode determination unit 510G determines to switch the detection mode from the first detection mode to the second detection mode for the front touch switch 203. . In this case, mode determination unit 510G generates a switching request signal for requesting switching from the first detection mode to the second detection mode for front touch switch 203.

In this case, the signal identification unit 521 outputs the activation signal FAS to the output signal generation unit 522. The output signal generation unit 522 generates an output signal in response to receiving the activation signal FAS.

  When a failure occurs in the front touch switch 203, a switch request signal for requesting switching from the first detection mode to the second detection mode is output from the mode determination unit 510G to the signal identification unit 521, and then the passer-by When entering the detection region, the detection signal generated by the front blind sensor 301 is output from the signal identification unit 521 to the output signal generation unit 522. The output signal generation unit 522 generates an output signal in response to reception of the detection signal.

  When the passerby touches the touch switch 204 after no malfunction occurs, the signal identification unit 521 receives the activation signal RAS from the reception unit 610G and receives the detection signal from the rear blind sensor 302. In this case, the signal identification unit 521 outputs the activation signal RAS to the output signal generation unit 522. The output signal generation unit 522 generates an output signal in response to receiving the activation signal RAS.

  When a malfunction occurs in the rear touch switch 204, a switch request signal for requesting switching from the first detection mode to the second detection mode is output from the mode determination unit 510G to the signal identification unit 521, and then a passer-by When entering the detection region, the detection signal generated by the rear blind sensor 302 is output from the signal identification unit 521 to the output signal generation unit 522. The output signal generation unit 522 generates an output signal in response to reception of the detection signal.

  The output signal is output from the output signal generation unit 522 to the drive signal generation unit 530G. The drive signal generation unit 530G converts the output signal into an open signal. The open signal is output from the drive signal generation unit 530G to the drive unit DRV. The drive unit DRV drives the door body DOR according to the open signal. As a result, the door body DOR is displaced from the closed position to the open position.

  Similar to the seventh embodiment, the drive signal generation unit 530G includes an open signal generation unit 531 and a closed signal generation unit 532. The description of the seventh embodiment is incorporated in these elements.

  Drive signal generation unit 530G further includes a timer 533G. Each detection signal generated by the front eyeless sensor 301 and the rear eyeless sensor 302 is output to the timer 533G. When the timer 533G receives one of the detection signals generated by the front seamless sensor 301 and the rear seamless sensor 302, the timer 533G sets the time measurement value to “0”. The drive signal generation unit 530G executes the processing of steps S115 to S150 described with reference to FIG. 6 to generate an open signal and a close signal.

<Ninth Embodiment>
According to the control principle described in connection with the eighth embodiment, each of the plurality of touch switches communicates with the control panel.

The control panel 600H communicates with the front touch switch 203H, but does not communicate with the rear touch switch 204H. When a passerby (not shown) moving from the rear space to the front space touches the rear touch switch 204H, the rear touch switch 204 uses the communication function of the front touch switch 203H so that the passerby can use the rear touch switch 204H.

Similarly to the eighth embodiment, the battery 210H supplies power to the activation signal generation unit 220H. In addition, the battery 210H supplies power to the rear touch switch 204H. The rear touch switch 204H operates under power supply from the battery 210H.

  Similarly to the sixth embodiment, the activation signal generation unit 220H includes a remaining amount detection unit 222, a signal generation unit 223, and a transmission unit 224. The description of the sixth embodiment is incorporated in these elements.

Before the switching request signal is output from the mode determination unit 510 to the signal selection unit 520H, the signal selection unit 520H selects the first activation signal as an output signal. Since the rear touch switch 204H uses the transmission unit 224 of the front touch switch 203H, if a failure occurs in at least one of the front touch switch 203H and the rear touch switch 204H, the switching request signal is selected from the mode determination unit 510.

The photoelectric sensor 700 emits a detection light beam that propagates along the optical axis to form an optical path. When the passerby blocks the optical path, the photoelectric sensor 700 generates a detection signal. The detection signal is output from the photoelectric sensor 700 to the control device 100I. Upon receiving the detection signal from the photoelectric sensor 700, the control device 100I displaces the door body DOR to the open position. If the door body DOR is in the open position when the detection light is output from the photoelectric sensor 700 to the control device 100I, the control device 100I performs control for keeping the door body DOR in the open position.

When the timer 533I receives one of the detection signals generated by the front seamless sensor 301 and the rear seamless sensor 302, the timer 533I sets the time measurement value to “0”. In addition, the detection signal generated by the photoelectric sensor 700 is also output to the timer 533I. Upon receiving the detection signal generated by the photoelectric sensor 700, the timer 533I sets the time measurement value to “0”. The drive signal generation unit 530I executes the processes of steps S115 to S150 described with reference to FIG. 6 to generate an open signal and a close signal.

The drive unit DRV displaces the door body DOR toward the closed position in response to the close signal.

<Eleventh embodiment>
According to the control principle described in relation to the fourth to tenth embodiments, the safety sensor (eyeless sensor) functions as an activation sensor under the second detection mode. In this case, when a human who does not intend to pass through the passage closed by the door body is detected by the safety sensor, the passage is opened. That is, the door body unnecessarily opens the passage. In the eleventh embodiment, an exemplary control device that performs control that makes it difficult to cause unnecessary opening of the passageway will be described.

  FIG. 19 is a schematic block diagram of a control device 100J of the eleventh embodiment. The control device 100J will be described with reference to FIG.

  Control device 100J further includes a control panel 600J. Similar to the sixth embodiment, the control panel 600J includes a receiving unit 610 and a failure detecting unit 400E. The description of the sixth embodiment is incorporated in these elements.

  Control panel 600J further includes a switching unit 500J. Similar to the sixth embodiment, the switching unit 500J includes a mode determination unit 510 and a drive signal generation unit 530C. The description of the sixth embodiment is incorporated in these elements.

  Switching unit 500J further includes a signal selection unit 520J. Similar to the sixth embodiment, the signal selection unit 520 </ b> J receives the first activation signal from the reception unit 610. The signal selection unit 520J receives the switching request signal from the mode determination unit 510. The first activation signal is output from the signal selection unit 520J to the open signal generation unit 531 as an output signal under the first detection mode. The description of the sixth embodiment is applied to the signal selection processing of the signal selection unit 520J under the first detection mode.

  The control device 100J further includes an invisible sensor 300J. As in the sixth embodiment, the eyeless sensor 300J outputs a detection signal to the timer 533. Unlike the sixth embodiment, the eyeless sensor 300J does not output to the signal selection unit 520J. The invisible sensor 300J functions exclusively as a safety sensor through the first detection mode and the second detection mode.

  The control device 100J further includes a preliminary activation element 710. The preliminary activation element 710 generates the second activation signal described with reference to FIG. The second activation signal is output from the preliminary activation element 710 to the signal selection unit 520J. The second activation signal is output from the signal selection unit 520J to the open signal generation unit 531 as an output signal under the second detection mode.

  FIG. 20 is a schematic diagram of the control device 101. The control device 101 is constructed based on the design principle of the control device 100J described with reference to FIG. The control apparatus 101 is demonstrated with reference to FIG.19 and FIG.20.

  Similar to the control device 100J, the control device 101 includes a touch switch 200E, an invisible sensor 300J, and a control panel 600J. The touch switch 200E is attached to the door body DOR. The blind sensor 300J is attached to the blind TSM. The eyeless sensor 300J emits detection light downward to define a detection area. The control panel 600J and the drive unit DRV are arranged in the seamless TSM.

  The control device 101 further includes a light emitting element 721 and a light receiving element 722. A set of the light emitting element 721 and the light receiving element 722 corresponds to the preliminary activation element 710 described with reference to FIG.

  The light emitting element 721 and the light receiving element 722 define an optical axis OAX that extends substantially horizontally. The optical axis OAX is three-dimensionally overlapped with the touch switch 200E. The light emitting element 721 emits a detection light beam that propagates along the optical axis OAX. If there is no obstacle between the light emitting element 721 and the light receiving element 722, the light receiving element 722 receives the detection light beam.

  A passerby who tries to open the door body DOR tries to touch the touch switch 200E. As a result, the passerby blocks the optical path of the detection light beam. At this time, the light receiving element 722 does not receive the detection light beam.

  The light receiving element 722 may generate a second activation signal that differs in voltage level depending on whether or not the detection light beam is received. For example, the light receiving element 722 that receives the detection light beam can generate a high voltage level signal. While no detection light is received, the light receiving element 722 can generate a low voltage level signal. After the switching request signal is output from the mode determination unit 510 (see FIG. 19) to the signal selection unit 520J (see FIG. 19), the signal selection unit 520J receives the low voltage level signal from the light receiving element 722. In response, an output signal may be generated. Since the output signal is output to the drive signal generation unit 530C in a timely manner, the door body DOR can be appropriately displaced toward the open position in accordance with a passer's action intended to open the door body DOR. it can. In many cases, a person who does not intend to open the door body DOR does not block the optical axis OAX, and therefore the door body DOR is not displaced unnecessarily toward the open position.

  FIG. 21 is a schematic diagram of the control device 102. The control device 102 is constructed based on the design principle of the control device 100J described with reference to FIG. The control apparatus 102 is demonstrated with reference to FIG.19 and FIG.21.

  Similar to the control device 100J, the control device 102 includes a touch switch 200E, an invisible sensor 300J, and a control panel 600J. The touch switch 200E is attached to the door body DOR. The blind sensor 300J is attached to the blind TSM. The eyeless sensor 300J emits detection light downward to define a first detection area. The control panel 600J and the drive unit DRV are arranged in the seamless TSM.

  The control device 102 further includes an optical sensor 730. The optical sensor 730 corresponds to the preliminary activation element 710 described with reference to FIG. The optical sensor 730 can also function as a safety sensor. In this case, the detection range of the safety sensor extends to the vicinity of the closed door DOR. Therefore, the passer-by can pass through the passport safely.

  Similar to the eyeless sensor 300J, the optical sensor 730 is attached to the eyeless TSM. The optical sensor 730 emits detection light downward and defines a second detection area that is narrower than the first detection area. The optical sensor 730 can detect a passerby who has entered the second detection region using a detection technique similar to that of the eyeless sensor 300J.

  The second detection area three-dimensionally overlaps with the touch switch 200E. A passerby who tries to open the door body DOR tries to touch the touch switch 200E. As a result, the passerby enters the second detection area. Therefore, the optical sensor 730 can detect a passerby who intends to open the door DOR. As a result, the optical sensor 730 can generate the second activation signal (see FIG. 19) in a timely manner. In many cases, a person who does not intend to open the door body DOR does not enter the second detection region. Accordingly, the door body DOR is difficult to open unnecessarily.

  The eyeless sensor 300J may detect a passerby using various known detection techniques. For example, the eyeless sensor 300J may determine the traveling direction of the passerby from detection areas defined using a plurality of spot areas. In this case, the blind sensor 300J may generate the detection signal only when the passerby moves toward the door DOR. As a result, the invisible sensor 300J can prevent an unnecessary opening / closing operation of the door DOR even when the touch switch 200E has a problem. The principle of this embodiment is not limited to the specific passer-by detection technique used by the eyeless sensor 300J.

  The touch switch 200K further includes a contact detection unit 221K and a signal generation unit 223K. The contact detection unit 221K detects contact by a passerby (not shown) and generates a contact signal. The contact signal is output from the contact detection unit 221 to the signal generation unit 223K. The signal generation unit 223K generates a first activation signal according to the contact signal. Unlike the eleventh embodiment, the first activation signal may not include the remaining amount information. The first activation signal is transmitted by the transmission unit 224.

  The control device 100K further includes a control panel 600K. Similar to the eleventh embodiment, the control panel 600K includes a drive signal generator 530C. The description of the eleventh embodiment is incorporated in the drive signal generation unit 530C.

The output signal generation unit 630 receives the second activation signal from the preliminary activation element 710.

  The output signal generation unit 630 includes a determination processing unit 631 and a signal generation unit 632. The determination processing unit 631 determines whether there is a problem with the touch switch 200K based on the first activation signal and the second activation signal. The signal generation unit 632 changes the output signal generation pattern based on the determination result of the determination processing unit 631. The output signal is output from the output signal generator 630 to the open signal generator 531.

<13th Embodiment>
An invisible sensor used as a safety sensor may have a function as a preliminary activation element described in relation to the eleventh embodiment and the twelfth embodiment. In the thirteenth embodiment, an exemplary control device having an invisible sensor that functions as a preliminary activation element is described.

  FIG. 24 is a schematic block diagram of a control device 100L of the thirteenth embodiment. The control device 100L will be described with reference to FIGS. Elements that are functionally common to the twelfth embodiment are denoted by the same reference numerals. The description of the twelfth embodiment is applied to elements having the same reference numerals.

  Similar to the twelfth embodiment, the control device 100L includes a touch switch 200K and a control panel 600K. The description of the twelfth embodiment is incorporated by these elements.

  The control device 100L further includes an invisible sensor 300L. The eyeless sensor 300L includes a main sensor element 310 and a sub sensor element 320. Similar to the twelfth embodiment, the main sensor element 310 functions as a safety sensor. Therefore, when main sensor element 310 detects a passerby, a detection signal generated by main sensor element 310 is output to timer 533. The secondary sensor element 320 functions as the preliminary activation element 710 described with reference to FIG. Accordingly, the sub sensor element 320 that detects the passerby generates the second activation signal. The second activation signal is output from the sub sensor element 320 to the output signal generation unit 630.

  FIG. 25 is a schematic diagram of the control device 100L. The control device 100L will be further described with reference to FIGS. 24 and 25. FIG.

To do. The invisible sensor 300L emits detection light from the light emitting element used for the sub sensor element 320 and defines the second detection region. The second detection area three-dimensionally overlaps with the touch switch 200K. A passerby who tries to touch the touch switch 200K enters the second detection area. Therefore, the eyeless sensor 300L can detect a passerby in the second detection area.

  As described in relation to the twelfth embodiment, the control panel 600K can displace the door body DOR to the open position in response to the second activation signal under the second detection mode. Therefore, even if a malfunction (for example, mechanical failure) occurs in the touch switch 200K and the first activation signal is not output, the passerby performs a contact operation similar to the contact operation with respect to the normal touch switch 200K, and the door body. DOR can be opened.

<Fourteenth embodiment>
The control principle described in relation to the fifth to thirteenth embodiments uses a mechanical sensor that receives a force from a passerby for generating the first activation signal. Instead of the mechanical sensor, an optical sensor may generate the first activation signal. In the fourteenth embodiment, an exemplary control device that generates a first activation signal using an optical sensor will be described.

  FIG. 26 is a schematic diagram of a control device 100M according to the fourteenth embodiment. The control device 100M will be described with reference to FIGS. 19 to 21 and FIG.

On the display board GDP, a message or a mark for prompting the passerby to contact is drawn. Therefore, a passerby who tries to open the door body DOR tries to touch the display panel GDP. Unlike the touch switch 200E, the display panel GDP does not generate the first activation signal.

  FIG. 26 shows a light emitting element 721, a light receiving element 722, and an optical sensor 730. As described with reference to FIG. 20, the set of the light receiving element 722 and the light emitting element 721 defines an optical path extending substantially horizontally. As described with reference to FIG. 21, the optical sensor 730 defines an optical path extending substantially vertically. That is, the optical sensor 730 defines an optical path that is different in direction from the optical path defined by the set of the light receiving element 722 and the light emitting element 721.

  When the passerby blocks the optical path of the optical sensor 730, the optical sensor 730 may generate the first activation signal instead of the touch switch 200E described with reference to FIG. In this case, the set of the light receiving element 722 and the light emitting element 721 is used as the preliminary activation element 710 described with reference to FIG.

  Alternatively, when the passerby blocks the optical path defined between the light receiving element 722 and the light emitting element 721, the combination of the light receiving element 722 and the light emitting element 721 is the touch switch described with reference to FIG. Instead of 200E, a first activation signal may be generated. In this case, the optical sensor 730 is used as the preliminary activation element 710 described with reference to FIG.

  In the present embodiment, the first optical sensor is exemplified by one of the optical sensor 730 and the set of the light receiving element 722 and the light emitting element 721. The second optical sensor is exemplified by the other of the set of the optical sensor 730 and the light receiving element 722 and the light emitting element 721.

Each of the plurality of light emitting elements is associated with each of the plurality of light receiving elements. Part of the plurality of sets of light emitting elements and light receiving elements is used to define the second detection region. The other set is used to define the first detection area. When the passerby enters the second detection area, the set of the light emitting element and the light receiving element that defines the second detection area generates a second activation signal. When one of the light emitting element and the light receiving element defining the second detection area fails, the light emitting element or the light receiving element defining the first detection area may be used to define an alternative second detection area. Good. In the fifteenth embodiment, an exemplary controller having an invisible sensor that defines an alternative second detection region is described.

The light emitting element group 330 includes a plurality of light emitting elements (not shown). Each of the plurality of light emitting elements emits detection light. The light receiving element group 340 includes a plurality of light receiving elements (not shown). Each of the plurality of light receiving elements is associated with each of the plurality of light emitting elements.

  Similar to the thirteenth embodiment, the control panel 600N includes a drive signal generator 530C. The description of the thirteenth embodiment is incorporated in the drive signal generation unit 530C.

  The control panel 600N includes a sensor control unit 640. The sensor control unit 640 includes a signal analysis unit 641 and a pattern storage unit 642. The light emitting element group 330 and the light receiving element group 340 define a detection region. The light receiving element group 340 generates a detection signal indicating whether or not a passerby exists in the detection area. The detection signal is output from the light receiving element group 340 to the signal analysis unit 641.

  The detection area includes a first detection area and a second detection area. The first detection region is defined in order for the invisible sensor 300N to function as a safety sensor. The second detection area is defined in order for the invisible sensor 300N to function as an activation sensor. The signal analysis unit 641 analyzes the detection signal from the light receiving element group 340 and determines whether or not a passerby exists in the first detection area and the second detection area.

  If the passerby is detected in the second detection area, the signal analysis unit 641 generates a notification signal for notifying that the passerby exists in the second detection area. This notification signal is output from the signal analysis unit 641 to the open signal generation unit 531. The open signal generation unit 531 generates an open signal in response to the notification signal. The open signal is output from the open signal generation unit 531 to the drive unit DRV. The drive unit DRV displaces the door DOR toward the open position in response to the open signal.

  If the passerby is detected in the first detection area, the signal analysis unit 641 generates a notification signal for notifying that the passerby exists in the first detection area. This notification signal is output from the signal analysis unit 641 to the timer 533. The timer 533 sets the time measurement value to “0” according to the notification signal. If the notification signal is not received from the signal analysis unit 641, the timer 533 increases the time measurement value. The closing signal generation unit 532 refers to the timer 533, and generates a closing signal if the measured value exceeds the timer threshold value. The closing signal is output from the closing signal generation unit 532 to the driving unit DRV. The drive unit DRV displaces the door body DOR toward the closed position in response to the close signal.

  FIG. 28 is a table showing exemplary data stored in the pattern storage unit 642. The control device 100N is described with reference to FIG. 27 and FIG.

For example, if the signal from the light receiving element is lost, the signal analyzing unit 641 may determine that a defect has occurred in the light receiving element. Alternatively, if the signal analysis unit 641 analyzes signal changes of a plurality of sets of light emitting elements and light receiving elements and finds that a detection signal related to a specific light emitting element has a specific signal change, The analysis unit 641 may determine that a defect has occurred in the specific light emitting element. The principle of this embodiment is not limited to a specific detection method for detecting a malfunction.

  The pattern storage unit 642 stores a combination pattern of a light emitting element and a light receiving element that can define a detection area that can be used as the second detection area. As shown in FIG. 28, in the initial setting (first pattern), the set of the light emitting element A and the light receiving element A is used to define the second detection region. During this time, the light emitting elements B and C are used as a safety sensor together with other light receiving elements. The light receiving element B is used as a safety sensor together with other light emitting elements. When the signal analysis unit 641 detects a malfunction of the light emitting element A, the signal analysis unit 641 refers to the pattern storage unit 642, and uses the detection area defined by the light emitting element B and the light receiving element A as the second detection area. Use (second pattern). When the signal analysis unit 641 detects a malfunction of the light receiving element A, the signal analysis unit 641 refers to the pattern storage unit 642, and uses the detection area defined by the light emitting element C and the light receiving element B as the second detection area. Use (third pattern).

  FIG. 29 shows the display panel GDP, the light receiving area of the light receiving element A, and the irradiation areas of the light emitting elements A and B. The overlapping area between the light receiving area of the light receiving element A and the irradiation area of the light emitting element A is three-dimensionally overlapped with the display panel GDP. Similarly, the overlapping area between the light receiving area of the light receiving element A and the irradiation area of the light emitting element B is three-dimensionally overlapped with the display panel GDP. A passerby who wants to touch the display panel GDP enters these overlapping regions.

  In the initial setting (first pattern), the signal analysis unit 641 uses the overlapping region between the light receiving region of the light receiving element A and the irradiation region of the light emitting element A as the second detection region. If a failure occurs in the light emitting element A, the signal analyzing unit 641 uses the overlapping area between the light receiving area of the light receiving element A and the irradiation area of the light emitting element B as the second detection area. Therefore, even after the optical axis defined between the light receiving element A and the light emitting element A disappears, the signal analysis unit 641 can continue to detect a passerby who tries to touch the display panel GDP.
