2. Configuration of the self-propelled unit 105 The appearance of the self-propelled unit 105 is shown in FIG. A configuration viewed from the outside of the self-running unit 105 will be described. Self-propelled unit 105 has electric power receiving part 105a, wheel 105c, wheel 105d, and case 105h.

  The power receiving unit 105 a receives power from the power supply device 107 by contacting a power supply unit 107 a (described later) of the power supply device 107. The wheels 105c and 105d move the self-propelled unit 105.

  The housing 105 h has a shape with a reduced thickness so as to be incorporated in the door 102. The housing 105h has a power receiving portion opening H1 and a near infrared sensor opening H3. The power receiving portion opening H1 is an opening for projecting the power receiving portion 105a to the outside. The near-infrared sensor opening H3 is an opening for irradiating the near-infrared rays from the near-infrared sensors 105b1 to 105b6 to the outside. Note that a total of two near-infrared sensor apertures H3 are provided at the left and right target positions. A cover is provided on the surface of the near-infrared sensor opening H3 in order to protect the internal near-infrared sensors 105b1 to 105b6 and to increase the near-infrared light projecting efficiency of the near-infrared sensors 105b1 to 105b6. It is attached.

  Next, a configuration viewed from the inside of the self-running unit 105 will be described with reference to FIG. The self-propelled unit 105 includes a power receiving unit 105a, near-infrared sensors 105b1 to 105b6, wheels 105c, wheels 105d, a DC motor 105e, a control unit 105f, and a battery 105g.

  The near-infrared sensors 105b1 to 105b6 sense whether or not there are passers-by or passersby in a predetermined area.

  The wheel 105c is connected to the DC motor 105e via a predetermined gear mechanism. Thereby, the driving force of the DC motor 105e is transmitted to the wheel 105c via the gear mechanism. That is, the wheel 105c becomes a drive wheel. On the other hand, the wheel 105d is an idle wheel.

  The DC motor 105e is connected to the control unit 105f. The control unit 105f opens and closes the door 102 by controlling the operation of the DC motor 105e.

  The control unit 105f is connected to the near infrared sensors 105b1 to 105b6. The near-infrared sensors 105b1 to 105b6 detect whether or not there is a passerby or a passing object in a predetermined area (hereinafter referred to as a detection area) from the door 102 toward the traveling direction a1.

  The battery 105g supplies power to the near-infrared sensors 105b1 to 105b6, the control unit 105f, and the like. The battery 105g is chargeable and stores the power received by the power receiving unit 105a.

  Here, the arrangement of the near infrared sensors 105b1 to 105b6 will be described with reference to FIG. As shown in FIG. 7A, the near-infrared sensors 105b1 to 105b3 are arranged so that near-infrared rays can be emitted from the surface P1 of the door 102 to the outside. Similarly, the near-infrared sensors 105b4 to 105b6 are arranged so that near-infrared rays can be emitted from the back surface P2 of the door 102 to the outside.

  Near-infrared sensor 105b1 forms detection region R1 from the corner formed by surface P1 and side surface P3 toward the closing direction (arrow a3close direction) of door 102 and the exit direction (arrow a1out direction). Further, as shown in FIG. 7B, the near-infrared sensor 105b2 forms a detection region R2 from the surface P1 toward the exit direction (arrow a1out direction). Furthermore, as shown in FIG. 7C, the near-infrared sensor 105b3 forms a detection region R3 from the surface P1 toward the opening direction (arrow a3open direction) of the door 102 and the exit direction (arrow a1out direction).

  The same applies to the near-infrared sensors 105b4 to 105b6 arranged on the back surface P2 side.

  In this manner, by forming different detection areas using the near-infrared sensors 105b1 to 105b6, the detection area can be changed according to the position of the door 102 with respect to the door frame 150 using the control unit 105f. Thereby, the automatic door 100 can pass a passerby etc. safely and smoothly. The detection area switching process according to the position of the door 102 with respect to the door frame 150 by the control unit 105f will be described later.

Configuration of Third Power Supply Device The hardware configuration of the power supply device 107 will be described with reference to FIG. The power supply apparatus 107 includes a power supply unit 107a and a power supply circuit 107b.

  The power supply unit 107 a supplies power to the power receiving unit 105 a of the self-running unit 105. Specifically, the power supply unit 107a has a power supply electrode that contacts the power receiving electrode of the power receiving unit. The power supply device 107 supplies power to the self-running unit 105 when the power receiving electrode and the power supply electrode of the power receiving unit come into contact with each other.

  The power supply circuit 107b is connected to electrical wiring. The electric power acquired from the electric wiring is subjected to a predetermined process such as voltage conversion to be electric power that can be supplied to the self-running unit 105.

Fourth Power Supply An outline of power supply will be described with reference to FIG. 9A. The power receiving unit 105 a of the self-running unit 105 receives power supply by contacting the power supply circuit 107 b of the power supply device 107. In this way, when supplying and receiving power, it is very effective in an automatic door system to supply power by contact between the power receiving unit 105a and the power supply unit 107a. In the automatic door system, the door 102 always opens and closes. That is, there always exists a closed state in which the door 102 is closed as shown in FIG. 9A. Therefore, in the closed state of the door 102, the power supply unit 107a and the power receiving unit 105a are brought into contact to supply power to the self-propelled unit 105, and the battery 105g is charged. It can be opened and closed by self-propelled. Further, the battery 105g of the self-propelled unit 105 can have a capacity capable of maintaining only power necessary for opening and closing the door 102 for one round trip. That is, the battery 105g can be reduced in size and capacity.

5th operation | movement The operation | movement of the control part 105f is demonstrated using the flowchart shown in FIG. When the CPU 191 of the control unit 105f determines that the power supply unit 107a and the power supply unit 107b are in contact, that is, the door 102 is closed (S901), the CPU 191 detects a human body or the like from the near-infrared sensors 105b3 and 105b6. It is determined whether or not to acquire human detection sensor information, which is sensor information indicating that it has been made (S903) (see FIG. 9A).

  When the CPU 191 acquires the human detection sensor information from the near-infrared sensors 105b3 and 105b6, the CPU 191 operates the DC motor 105e to operate the self-running unit 105 in the opening direction (FIG. 9A: arrow a3open direction) (S905).

  When the CPU 191 determines that the door 102 has been opened (S907), the CPU 191 determines whether a predetermined time has elapsed (S909). The determination of the elapse of the predetermined time in step S909 is for maintaining the open state for a predetermined time after the door 102 is opened. The person detected by the near-infrared sensors 105b3 and 105b6 passes through the door 102 during the time that this open state is maintained. Whether the door 102 has been opened or not is determined by acquiring the rotational speed of the DC motor 5 or the rotational speed of the wheel 105 using an encoder or the like, and calculating the position of the door 102. For example, a method of opening the door when it stops moving further, a method of arranging a position sensor for detecting the position of the door 102 at a predetermined position, and the like are used as appropriate.

  When determining that the predetermined time has elapsed, the CPU 191 determines whether or not to acquire human detection sensor information from the near infrared sensors 105b1 and 105b4 (S911) (see FIG. 9B). When the CPU 191 determines that the human detection sensor information has been acquired from the near infrared sensors 105b1 and 105b4, the CPU 191 maintains the open state of the door 102 (S913).

  If the CPU 191 determines that the predetermined time has elapsed without acquiring the human detection sensor information from the near infrared sensors 105b1 and 105b4 (S915), the DC motor 105e is driven to close the door 102 (FIG. 9C: arrow a3close direction). ) (S917).

  When the CPU 191 determines that the door 102 has reached a predetermined position while moving in the flat direction (S919), the CPU 191 determines whether to acquire human detection sensor information from the near-infrared sensors 105b2 and 105b5 (S921) (FIG. 9). 9C). When CPU 191 determines that the human detection sensor information has been acquired from near-infrared sensors 105b2 and 105b5, CPU 191 moves door 102 in the opening direction (FIG. 9C: arrow a3open direction) (S923). On the other hand, if the CPU 191 does not acquire the human detection sensor information from the near-infrared sensors 105b2 and 105b5, it closes the door 102 as it is (S925).

  In this way, by changing the detection direction of the person depending on the position of the door 102, a passerby or the like can be detected in an appropriate detection area corresponding to the position of the door 102. For example, when the door 102 is in the closed state, it is an appropriate detection region in the closed state, and when it is in the open state, it is an appropriate detection region in the open state. It is possible to detect a passerby or the like in the appropriate value detection area during the movement.

  In the first embodiment described above, power is supplied to the self-propelled unit 105 by contact between the power receiving unit 105a and the power supply circuit 107b when the door 102 is closed. On the other hand, the automatic door in the present embodiment receives power from the self-propelled unit 105 by magnetic resonance. In the following, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.

First Configuration The automatic door system according to the present embodiment basically has the same configuration as the automatic door 100 according to the first embodiment. However, the configurations of the power receiving unit 105a and the power supply device 107 are different. In the first embodiment, the power supply unit 105a and the power supply unit 107a of the power supply apparatus 107 have connector shapes that are in contact with each other. However, the power reception unit 105a and the power supply unit 107a according to the present embodiment are mutually connected. The power is supplied and received by utilizing the resonance of the magnetic field formed by the electromagnetic wave without directly contacting the. Below, the structure of the electric power receiving part 105a and the electric power supply apparatus 107 is demonstrated.

1. Configuration of Power Receiving Unit 105a and Power Supply Device 107 The configuration of the power receiving unit 105a according to the present embodiment will be described with reference to FIG. The power receiving unit 105 a includes a control circuit 311, a memory 312, a power receiving circuit 313, and a communication circuit 317.

  The control circuit 311 performs control such as reception of electromagnetic waves by the power receiving circuit 313. The memory 312 records and holds various temporary data. The power receiving circuit 313 includes a resonator 315. The power reception circuit 213 transmits power to and from a power transmission circuit 215 (described later) of the power supply unit 107a using resonance of a magnetic field formed by electromagnetic waves.

  Next, a hardware configuration of the power supply apparatus 107 according to the present embodiment will be described with reference to FIG. The power supply apparatus 107 includes a control circuit 211, a memory 212, a power transmission circuit 213, and a communication circuit 217. The control circuit 211 controls transmission of electromagnetic waves by the power transmission circuit 213, wireless communication by the communication circuit 217, and the like. The memory 212 records and holds various temporary data. The power transmission circuit 213 includes a resonator 215. The power transmission circuit 213 transmits power to and from a power reception circuit 315 (described later) of the power reception device 31 using resonance of a magnetic field formed by electromagnetic waves.

  An example of a technique for transmitting power using resonance of a magnetic field formed by electromagnetic waves is a power transmission system 500 shown in FIG. The power transmission system 500 includes an AC power source 501, a coil 503, a coil 505, and an incandescent lamp 507.

  The AC power source 501 is a Colpitts oscillation circuit, and generates AC continuously. The coil 503 and the coil 505 are made of copper wire. The coil 503 and the coil 505 both have a coil radius of about 30 cm. The coil 503 and the coil 505 function as an LC resonator. Here, although no external capacitor exists in the coil 503 and the coil 505, the diameter of the copper wire is set to 6 mm in order to form a parasitic capacitance.

  The resonance characteristics of the coil 503 as a single unit are a resonance frequency of about 10 MHz, a theoretical Q value of about 2300, and a measured Q value of about 950. The coil 505 is the same as the coil 103. The inter-coil distance L between the coil 503 and the coil 505 is about 200 cm. In this manner, the AC power source 501, the coil 503, the coil 505, and the incandescent lamp 507 are arranged, and a current is supplied using the AC power source 501. As a result, electromagnetic induction current flows through the coil 503 due to electromagnetic induction between the AC power source 501 and the coil 503. A magnetic field is formed around the coil 503 by the electromagnetic induction current. A predetermined current flows through the coil 505 due to local resonance. An electromagnetic induction current flows through the incandescent lamp 507 by electromagnetic induction between the coil 505, the incandescent lamp 507, and the coil 505, and the incandescent lamp 507 disposed away from the AC power source 501 can be turned on. In other words, the power supply system 500 enables remote power transmission (Marin Soljacic et. Al., “Developing a technology to wirelessly transmit power / lighting a 60 W light bulb through experiments”, Nikkei Electronics, 3.12. 2007, p.117-p.128).

  In this way, power can be supplied to the self-running unit 105 at all times by supplying and receiving power by utilizing the resonance of the magnetic field formed by the electromagnetic waves. Therefore, the automatic door 100 can be operated at any time.

  In the above-described first embodiment, the door 102 of the automatic door 100 is suitable for a sliding door whose opening / closing direction is an intersection direction in which the door 102 intersects the passing direction of the passerby. The automatic door 300 according to the present embodiment is suitable for a hinged door whose opening / closing direction is a direction in which the door is along the traveling direction of the passerby.

1. Overall Configuration The overall configuration of the automatic door 300 according to the present embodiment will be described with reference to FIG. FIG. 15 shows a state where the automatic door 300 is installed in the passage.

  The automatic door 300 is a so-called hinged door that opens and closes in a rotational direction a33 with respect to a passer-by direction a31. The automatic door 300 rotates about a hinge 309 that connects the door frame 350 and the door 302 arranged along the periphery of the passage as a rotation axis. In addition, in FIG. 15, description is abbreviate | omitted about the latch which goes in and out by rotation of a doorknob and a doorknob.

  The automatic door 300 includes a door 302, a self-running unit 305, and a power supply device 307. The door 302 is fixed to the door frame 350 by a hinge 309. The door 302 is opened and closed by the self-propelled unit 305. A sensor hole 302 a for irradiating detection light of a near infrared sensor 305 b (described later) is formed in the lower portion of the door 302.

  The door 302 has a self-propelled unit 305 inside. On the side edge 350s side of the door 302 on the door frame 350 side, a power receiving unit 305a is disposed.

  A power supply device 307 is arranged inside the side edge 350 s of the door frame 350. Further, the side edge 350s of the door frame 350 is provided with an opening 350a that fits into the power receiving unit 305a. The power supply device 307 supplies and receives power to and from the power receiving unit 305a through the opening 350a.

  Next, a sectional view of the automatic door 300 and the door frame 350 shown in FIG. 15 in the closed state is shown in FIG. A self-propelled unit 305 is disposed inside and below the door 302. The self-propelled unit 305 has a power receiving unit 305 a on the side edge 350 s side of the door frame 350. The internal configuration of the self-running unit 305 will be described later.

  The power supply device 307 includes a power supply unit 307a. The power supply device 307 supplies and receives power with the power receiving unit 305a via the power supply unit 307a. The power supply unit 307a and the power reception unit 305a are connected by a predetermined connector.

  Next, an appearance of the door 302 is shown in FIG. 17A. The door 302 has a sensor hole 302a in the lower part of the door frame 350 on the side edge 350s side. The sensor holes 302a are respectively formed on both the front surface P31 and the back surface P32 of the door 302. Further, the door 302 has an opening 302b in the lower portion of the side surface P33. The power receiving unit 305a of the self-running unit 305 is inserted into the opening 302b. The tip of the power receiving unit 305 a inserted into the opening 302 b is located outside the door 302. Accordingly, the power receiving unit 305a supplies and receives power with the power supply device 307 disposed outside.

  A cross-sectional view of the door 102 is shown in FIG. 17B. The door 302 has a self-propelled unit arrangement space 302s for accommodating the self-propelled unit 305 therein. Note that the self-running unit arrangement space 302s communicates with the sensor hole 302a and the opening 302b.

2. Configuration of the self-propelled unit 305 FIG. The self-propelled unit 305 includes a power receiving unit 305a, a drive wheel unit 305c, and a housing 305h. The power receiving unit 305a and the housing 305h are the same as the power receiving unit 105a and the housing 105h in the self-propelled unit 105, respectively.

  On the other hand, the drive wheel unit 305c is disposed below the self-running unit 305. An appearance of the drive wheel unit 305c is shown in FIG. The drive wheel unit 305c is driven by itself to open and close the door 302.

  The drive wheel unit 305c has wheels 305c1, a fixed plate 305c3, a drive device 305c5 (not shown), a gyro sensor 305c7 (not shown), and a connector 305c9. The wheel 305c1 rotates in the arrow a18 direction around the axis J1. Further, the wheel 305c1 freely rotates in the direction of the arrow a28 around the axis J3. Thereby, the wheel 305c1 can rotate appropriately according to the moving direction of the door 302.

  The fixed plate 305c3 fixes the drive wheel unit 305c to the housing 305h of the self-running unit 305.

  The drive device 305c5 is disposed inside the drive wheel unit 305c. The drive wheel unit 305c drives the wheel 305c1 based on a control signal from a control unit 305f (described later). The driving device 305c5 is connected to the wheel 305c1 through a predetermined gear mechanism. As a result, the driving force of the driving device 305c5 is transmitted to the wheel 305c via the gear mechanism. The driving device 305c5 is connected to the control unit 305f via the connector 305c9. The control unit 305f opens and closes the door 302 by controlling the operation of the driving device 305c5.

  The gyro sensor 305c7 detects the angular velocity due to its movement and transmits it to the control unit 305f. The control unit 305f calculates an angle at which the gyro sensor 3057c has moved, that is, an angle at which the door 302 has moved, by an integral calculation process based on the angular velocity acquired from the gyro sensor 305c7.

  The connector 305c9 mediates transmission / reception of signals between the drive unit 305c7 and the gyro sensor 305c7 and the control unit 305f.

  Next, the internal configuration of the self-running unit 305 will be described with reference to FIG. The self-propelled unit 305 includes a power receiving unit 305a, near infrared sensors 305b1 to 305b6, a control unit 305f, a battery 305g, and a connector 305h.

  The near-infrared sensors 305b1 to 305b6 sense whether or not there are passersby or objects to pass in a predetermined area.

  The control unit 305f is connected to the near infrared sensors 305b1 to 305b6. Moreover, it is connected with the drive device 305c5 and the gyro sensor 305c7 of the drive wheel unit 305c via the connector 305h.

  The near-infrared sensors 305b1 to 305b6 detect whether or not a passerby or a passing object is present in a detection region from the door 302 toward the passage direction (the direction of arrow a31: see FIG. 15).

  The battery 305g supplies power to the near infrared sensors 305b1 to 305b6, the control unit 305f, the driving device 305c5 of the driving wheel unit 305c, and the gyro sensor 305c7. The battery 305g can be charged and stores the power received by the power receiving unit 305a.

  Here, the arrangement of the near-infrared sensors 305b1 to 305b6 will be described with reference to FIG. FIG. 21A shows a closed state in which the door 302 is completely closed. As shown in FIG. 21A, the near-infrared sensors 305b1 to 305b3 are arranged so that near-infrared rays can be emitted from the surface P31 of the door 302 toward the outside. Similarly, the near-infrared sensors 305b4 to 305b6 are arranged so that near-infrared rays can be emitted from the back surface P32 of the door 302 to the outside.

  Near-infrared sensor 305b1 forms detection region R31 that covers the width of the passage from surface P31 toward the opening direction (arrow a33open direction) of door 302 in the closed state. The detection region R31 extends farther than the tip position of the door 302 in the open state. Thereby, a passerby is prevented from passing or being hit by the door 302 due to the opening operation of the door 302.

  On the other hand, the near-infrared sensor 305b5 forms a detection region R35 that covers the width of the passage from the surface P32 toward the closing direction (arrow a31close direction) of the door 302 in the closed state.

  FIG. 21B shows a state (state 1) where the door 302 is opened from the closed state by an angle θ1. State 1 shows a state in which the detection region R31 formed by the near-infrared sensor 305b1 begins to overlap with the wall of the passage. When the detection region R31 overlaps with the wall, the near infrared sensor 305b1 detects the wall as an object, and the automatic door 300 malfunctions. Therefore, from the closed state to the state 1, the near infrared sensor 305b1 and the near infrared sensor 305b5 are operated. Before the detection region R31 overlaps the side wall of the passage, the control unit 305f switches the near infrared sensor 305b1 to the near infrared sensor 305b2. The same applies to the near infrared sensor 305b5.

  FIG. 22A shows a state (state 2) in which the door 302 is opened by an angle θ2 from the closed state. State 2 shows a state in which the detection region R32 formed by the near-infrared sensor 305b2 starts to overlap with the wall of the passage. The near-infrared sensor 305b2 forms a detection region R32 from the direction perpendicular to the surface P31 (arrow a33open direction) toward the direction closer to the door 302.

  From state 1 to state 2, the near infrared sensor 305b2 and the near infrared sensor 305b6 are operated. By operating the near-infrared sensor 305b2, in the closing operation of the door 302, a person or an object between the door 302 and the wall of the passage can be detected. Thereby, the accident by the collision with the door 302, a person, etc. can be prevented. The detection region R32 is formed so that it can be detected farther than the detection region R33.

  On the other hand, the near-infrared sensor 305b6 forms a detection region R36 from the direction perpendicular to the surface P32 (arrow a33close direction) toward the direction closer to the door 302.

  FIG. 22B shows a state (state 3) in which the door 302 is opened by an angle θ3 from the closed state. State 3 shows a state in which the detection region R33 formed by the near-infrared sensor 305b3 begins to overlap the passage wall. The near-infrared sensor 305b3 forms a detection region R33 from the direction perpendicular to the surface P31 (arrow a33open direction) toward the direction closer to the door 302 than the detection region R32. Before the detection region R32 overlaps the side wall of the passage, the control unit 305f switches the near infrared sensor 305b2 to the near infrared sensor 305b3.

  FIG. 22C shows the door 302 fully open. When the door 302 is opened, the control unit 305f switches to the near-infrared sensors 305b4 and 305b6. Note that the near-infrared sensor 305b4 forms a detection region R34 from the direction perpendicular to the surface P32 (arrow a33close direction) toward the power receiving unit 305a. In the open state, the detection region R36 by the near-infrared sensor 305b6 is formed from the direction perpendicular to the surface P32 (arrow a33close direction) toward the door 302. By the detection areas R34 and R36, a person or an object can be detected in advance so that a passerby is not obstructed by the operation of the door 302 from the open state to the closed state when the passerby passes.

  In this way, by forming different detection areas using the near-infrared sensors 305b1 to 305b6, the detection area can be changed according to the position of the door 302 using the control unit 305f. Thereby, the automatic door 300 can pass a passerby etc. safely and smoothly. The detection area switching process according to the position of the door 302 by the control unit 305f will be described later.

Configuration of Third Power Supply Device and Supply / Reception of Power The hardware configuration of the power supply device 307 is the same as that of the power supply device 107 in the first embodiment. The power supply method using the self-running unit 305 and the power supply device 307 is the same as in the first embodiment.

Fourth Operation The operation of the control unit 305f will be described using the flowchart shown in FIG. When the power supply unit 307a and the power supply unit 307b are in contact with each other, that is, when the door 302 is closed, the CPU 391 of the control unit 305f uses sensor information indicating that a human body has been detected from the near infrared sensors 305b1 and 105b5. It is determined whether or not certain human detection sensor information is acquired (S2303) (see FIG. 21A).

  When the CPU 391 acquires human detection sensor information from the near-infrared sensors 305b1 and 305b5, the CPU 391 transmits a control signal for operating the driving device 305c5 to operate the self-running unit 305 (S2305). When the CPU 391 is currently closed, the CPU 391 operates the self-running unit 305 so as to be in the open state.

  When the CPU 391 acquires the angular velocity signal from the gyro sensor 305c7 (S2307), the CPU 391 calculates the angle at which the door 302 has moved (S2309). When the CPU 391 determines that the calculated angle is a predetermined switching angle (see FIG. 22: θ1 to θ4) (S2311), the near-infrared sensor currently operating is switched to a predetermined near-infrared sensor (S2313). The relationship between the angle at which the door 302 has moved and the near infrared sensor to be operated is stored in advance in a storage device such as a predetermined memory.

  If the CPU 391 determines that the door 302 has been opened from the calculated angle (S2315), it acquires human detection sensor information that is sensor information indicating that a human body has been detected from the near infrared sensors 305b4 and 305b6 (see FIG. 22C). It is determined whether or not to perform (S2317). When the CPU 391 acquires the human detection sensor information from the near infrared sensors 305b4 and 305b6, the CPU 391 maintains the open state of the door 302 (S2319).

  When the CPU 391 determines that a predetermined time has elapsed without acquiring human detection sensor information from the near infrared sensors 305b4 and 305b6 (S2321), the CPU 391 transmits a control signal for operating the driving device 305c5 to operate the self-running unit 305. (S2305). Note that the CPU 391 operates the self-running unit 305 so as to be in the closed state when it is currently in the open state.

  The determination of the elapse of the predetermined time in step S2321 is to maintain the open state for a predetermined time after the door 302 is opened. The passers-by detected by the near-infrared sensors 305b1 to 305b6 pass through the door 302 during the time that this open state is maintained.

  If the CPU 391 determines in step S2315 that it is not in the open state, and further determines that it is not in the closed state (S2323), it determines that the door 302 is in operation, and repeats the processing in steps S2307 to S2315.

  If it is determined in step S2317 that it is in the closed state, if there is no end of operation such as power-off (S2325), the processing in steps S2303 to S2325 is repeated.

  When the CPU 391 acquires detection information indicating that an object has been detected from the currently operating near-infrared sensor, the CPU 391 executes a predetermined safety measure such as stopping the door 302.

  In this way, by changing the detection direction of the person depending on the position of the door 302, a passerby or the like can be detected in an appropriate detection area corresponding to the position of the door 302. For example, when the door 302 is in the closed state, it is an appropriate detection region in the closed state, and when it is in the open state, it is an appropriate detection region in the open state. It is possible to detect a passerby or the like in an appropriate detection area during the movement.

  Note that the position information of the door 302 may be acquired by using an encoder or the like built in the hinge 309 or attached near the hinge 309 to obtain angle information indicating the door position. Or you may make it utilize a limit switch for judgment of an open state and a closed state.

[Other Examples]
(1) Near-infrared sensor: In the above-described first embodiment, the near-infrared sensors 105b1 to 105b6 are used as the passer-by detection means. However, the present invention is not limited to the example as long as the passer-by can be detected. For example, light rays other than near infrared rays and sound waves may be used.

  Further, the number of near infrared sensors to be arranged is not limited to the example as long as a passerby can be detected appropriately. A large number of sensors may be added, and the detection area may be changed more finely based on the movement position of the door 102. Furthermore, the position where the near-infrared sensor is arranged is not limited to the example as long as a passerby can be detected appropriately.

  Furthermore, although the near-infrared sensors 105b1 to 105b6 irradiate near-infrared rays in parallel with the floor, the near-infrared sensors 105b1 to 105b6 are not limited to the examples as long as they can appropriately detect passers-by.

  The same applies to the near-infrared sensors 305b1 to 305b6 in the third embodiment.

  (2) Shapes of power receiving unit and power supplying unit: In the above-described first embodiment, the power receiving unit 105a and the power supplying unit 107a have connector shapes that come into contact with each other. It doesn't matter. For example, it may be in the form of an outlet plug as installed in a general household.

  The same applies to the power receiving unit 305a and the power supply unit 307a in the third embodiment.

  (3) Coupling of power receiving unit and power supplying unit: In the above-described first embodiment, the power receiving unit 105a and the power supplying unit 107a are further provided with attracting means such as magnets for attracting each other, and adhesion at the time of coupling You may make it raise.

  The same applies to the power receiving unit 305a and the power supply unit 307a in the third embodiment.

  (4) Arrangement position of power supply unit: In the first embodiment, power is supplied to the battery 105g in the closed state, but power is supplied to the battery 105g even in the open state. It may be. In this case, as shown in FIG. 14, the power supply unit 105a ′ is disposed at a position opposite to the position where the power receiving unit 105a of the self-running unit 105 is disposed, and further corresponds to the power supply unit 105a ′. What is necessary is just to arrange | position the electric power supply part 107a 'to the side edge of the door frame 150 to perform. Thereby, even when the open state is maintained for a very long time, the discharge of the battery 105g can be prevented, and the closing operation cannot be prevented due to the discharge.

  (4) Power receiving unit, power supplying unit: In the above-described second embodiment, the power receiving unit 105a and the power supplying unit 107a supply and receive power without contact with each other. Although resonance is used, the power receiving unit 105a and the power supply unit 107a are not limited to the examples as long as they can supply and receive power without contacting each other.

  In addition, the power supply unit 305a and the power supply unit 307a in the above-described third embodiment use the resonance of the magnetic field formed by the electromagnetic wave. For example, the power supply unit 305a and the power supply unit 307a supply and receive power without contacting each other. It is good also as what performs.

  (5) Power supply device: In the above-described first embodiment, the power supply device 107 is disposed inside the side edge 150s of the door frame 150. However, the power supply device 107 is configured to supply power to the power receiving unit 105a. The position is not limited to the example as long as it can be received. For example, a non-contact method using an electromagnetic induction power feeding method may be used. In the case of the electromagnetic induction power feeding method, unlike the magnetic field resonance technique of the second embodiment, since it reaches only a short distance (about 0 to 10 mm), the power supply unit 107a and the power receiving unit are in a closed state (when power is supplied). 105a is brought close to each other.

  The same applies to the power supply device 307 in the third embodiment.

  (6) Battery: In the above-described second embodiment, the self-propelled unit 105 has the battery 105g, but may not have the battery 105g. Since electric power can be supplied and received at any time by magnetic field resonance, the self-propelled unit 105 may be able to self-propell the door 102 without having the battery 105g.

  (7) Selection of near-infrared sensor: In the above-described first embodiment, the control unit 105f controls the operation of the near-infrared sensors 105b1 to 105b6 according to the flowchart shown in FIG. If it can select and operate | move appropriately, it will not be limited to the thing of illustration.

  The same applies to the near-infrared sensors 305b1 to 305b6 in the third embodiment.

  (8) Addition of near-infrared sensors in the moving direction: In the first embodiment, the near-infrared sensors 105b1 to 105b3 and the near-infrared sensors 105b4 to 105b6 are arranged on the front surface P1 and the back surface P2 of the door 102 of the door 102, respectively. However, a near-infrared sensor may be disposed on the side surface P3 of the door 102 on the side where the power supply unit 105a is disposed (see FIG. 7). Thereby, the closing direction of the door 102 (arrow a3close direction), that is, the traveling direction of the door 102, the person stationary on the traveling part of the door 102 can be detected, and the collision between the person and the door can be prevented. In this case, a reflecting plate may be disposed on the side edge 150s of the door frame 150, and a light receiving portion of the near infrared sensor may be disposed on the side surface P3 of the door 102. Since it is possible to immediately detect the interruption of infrared rays by an object such as a person, the movement of the door 102 can be reversed or the open state can be maintained.

  Alternatively, without a reflector, the fluctuation amount of the received light amount of the near-infrared sensor during the opening / closing operation is measured in advance and held as a reference state, and the received light amount actually obtained from the near-infrared sensor during the opening / closing operation is measured. It may be determined whether a person, an object, or the like exists in the traveling direction of the door 102 by comparing the fluctuation and the quantity reference state.

  The same applies to the near-infrared sensors 305b1 to 305b6 in the third embodiment.

  (9) Configuration of near-infrared sensor: In the first embodiment, the near-infrared sensors 105b1 to 105b6 may be removable as a unit. Thereby, a suitable near-infrared sensor can be easily selected according to the place where the automatic door 100 is disposed and the use situation.

  For example, the near-infrared sensors 105b1 to 105b6 may be formed as one unit, and the near-infrared sensors 105b4 to 105b6 may be formed as one unit without using all the near-infrared sensors 105b1 to 105b6 as one unit. . Furthermore, you may make it form a unit by another combination. Thereby, a more suitable near-infrared sensor can be selected according to an installation place or use condition.

  The same applies to the near-infrared sensors 305b1 to 305b6 in the third embodiment.

Further, a near-infrared sensor may be disposed on the handle portion of the door 102. Thereby, when a person reaches for the door with a natural motion, the near-infrared sensor can detect the hand and start the door opening operation. Furthermore, you may make it attach to the upper part of the door 102. FIG. Thereby, it becomes possible to detect a person close to the door 102 from a place 1 to 2 m away, and the opening operation of the door 102 can be started at a timing at which the person can pass naturally. In any example, a near infrared sensor may be attached to both sides or one side of the door 102 depending on the application. Further, instead of the near-infrared sensor disposed at the handle portion of the door 102, a simple push button, a touch switch, or the like may be disposed. In this case, you may use together the near-infrared sensor arrange | positioned in another position.

  (12) Configuration of Wheel 105c and Wheel 105d: In the first embodiment described above, the wheel 105c is a driving wheel and the wheel 105d is an idle wheel, but the wheel 105d may be a driving wheel in order to ensure that the door travels. Moreover, you may add the 3rd and 4th wheel as needed.

(13) Arrangement position of the power supply device 107: In the first embodiment, the power supply device 107 is arranged inside the side edge 150s of the door frame 150 with which the door 102 contacts in the closed state so that the power supply device 107 can receive power supply in the closed state. Although the power supply / demand unit 105a is disposed in the door 102, when the door 102 is in a fully opened state for a long time, the door 102 is placed inside the side edge of the door frame 150 that is in contact with the door 102 so that power is received in the opened state. The power supply / demand unit 105a may be arranged. Further, the power supply / demand unit 105a may be arranged on both side edges of the door frame 150 that are in contact with each other so that power can be supplied in either the closed state or the open state of the door 102. It may be provided.

The present invention can be used in an automatic door system.
