[0004] The above-mentioned locking / unlocking control device 1 has the following points that need to be improved: The locking / unlocking control device 1 can automatically open and close the thumb turn, but it cannot manage people entering and leaving a room, in other words, it cannot function as an entrance / exit management device.

[0005] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide an entrance / exit management device that can accurately and simply manage the entrance / exit of people. Effect of the Invention

[0006] The means for solving the problems in the present invention and the effects of the invention are described below.

[0007] The entry and exit management device of the present invention has a human detection unit that detects a person in a specified human detection area and provides human detection status information indicating that the person has been detected, and includes a first passing area and a second passing area through which the person passes, which are arranged adjacent to and facing each other at a specified opening / closing section, with the opening / closing section as the boundary, a human detection unit that forms the human detection area in the first passing area, an open / close detection unit that detects the open and closed states of the opening / closing section and provides open / close detection status information indicating that the opening / closing section is in the open state or closed state, and a control unit that acquires the human detection information and the open / close detection status information and manages the entry and exit of the person into the space on the first area side or the space on the second area side.

[0008] This makes it possible to accurately and easily manage people entering and exiting a room simply by installing the human detection unit and the open / close detection unit.

[0009] In the entry and exit management device of the present invention, the control unit acquires the person detection status information before acquiring the open / close detection status information, and then acquires the open / close detection status information indicating the open state of the open / close section, and after acquiring the open / close detection status information indicating the open state, acquires the open / close detection status information indicating the closed state of the open / close section, and if the person detection status information is not acquired for a predetermined period of time after acquiring the open / close detection status information indicating the closed state, it determines that the person has exited from the space on the first area side to the space on the second area side.

[0010] This makes it possible to accurately and easily manage people entering and leaving the room by using the detection of people by the human detection unit and the opening and closing of the opening / closing unit by the opening / closing detection unit. In particular, it is possible to accurately and easily manage the exit of people from the room.

[0011] In the entry and exit management device of the present invention, the control unit acquires the person detection status information before acquiring the open / close detection status information, and then acquires the open / close detection status information indicating the open state of the open / close section, and after acquiring the open / close detection status information indicating the open state, acquires the open / close detection status information indicating the closed state of the open / close section, and when acquiring the person detection status information after acquiring the open / close detection status information indicating the closed state, it determines that the person did not exit from the space on the first area side to the space on the second area side.

[0012] This allows accurate and simple management of people entering and leaving the room by using the detection of people by the human detection unit and the opening and closing of the opening / closing unit by the opening / closing detection unit. In particular, it allows accurate and simple management of cases where people do not leave the room.

[0013] In the entry and exit management device of the present invention, the control unit is characterized in that before acquiring the human detection status information, it acquires the open / close detection status information indicating the open state of the opening / closing section, and then acquires the open / close detection status information indicating the closed state of the opening / closing section, and if it acquires the human detection information after acquiring the open / close detection status information indicating the closed state, it determines that the person has entered from the space on the second area side to the space on the first area side.

[0014] This makes it possible to accurately and easily manage people entering and leaving the room by using the detection of people by the human detection unit and the opening and closing of the opening / closing unit by the opening / closing detection unit. In particular, it is possible to accurately and easily manage the entry and exit of people.

[0015] In the entry and exit management device of the present invention, the control unit is characterized in that, before acquiring the human detection status information, it acquires the open / close detection status information indicating the open state of the opening / closing section, and then acquires the open / close detection status information indicating the closed state of the opening / closing section, and if it does not acquire the human detection status information for a predetermined period of time after acquiring the open / close detection status information indicating the closed state, it determines that the person did not enter the space on the second area side from the space on the first area side.

[0016] This allows accurate and simple management of people entering and leaving the room by using the detection of people by the human detection unit and the opening and closing of the opening / closing unit by the opening / closing detection unit. In particular, it allows accurate and simple management of cases where people do not enter the room.

[0017] In the entry / exit management device of the present invention, the control unit is characterized in that it disables the acquisition of the human detection status information from the time it acquires the opening / closing detection status information indicating the open state of the opening / closing section until it acquires the opening / closing detection status information indicating the closed state of the opening / closing section.

[0018] This makes it possible to manage people's entry and exit using only the necessary human detection status information.

[0019] In the entry and exit control device according to the present invention, the open / close detection unit detects the open state and the closed state of the open / close unit by a change in magnetic force.

[0020] This makes it possible to easily detect the open / closed state of the opening / closing section.

[0021] The entry and exit control device according to the present invention further includes a locking device for locking and unlocking the opening / closing unit, and a locking / unlocking detection unit for monitoring a locked / unlocked state of an operation unit that switches between a locked state and an unlocked state by human operation, the locking / unlocking detection unit monitoring the locked / unlocked state of the operation unit, the operation unit fluctuation range being a range in which the state of the operation unit fluctuates between the unlocked state and the locked state, the operation unit fluctuation range being a range in which the state of the operation unit fluctuates between the unlocked state and the locked state, the operation unit fluctuation range being a range in which the operation unit fluctuates between the unlocked state and the locked state, the operation unit fluctuation range being a range in which the operation unit fluctuates when the opening / closing unit is in the closed ... The lock / unlock detection unit receives reflected light and provides information of the received reflected light as lock / unlock state information, and the control unit executes a lock / unlock determination process to determine whether the state of the locking device in the detection information is locked and / or unlocked, using reference locking state information indicating the preset light receiving state in the locked state of the locking device and / or reference unlocking state information indicating the preset light receiving state in the unlocked state of the locking device.

[0022] This makes it easy to determine whether the lock / unlock unit is locked or unlocked.

[0023] In the entry and exit management device according to the present invention, the control unit, in the lock / unlock determination process, further notifies the determined locked state and / or unlocked state.

[0024] This makes it possible to easily inform the user of the locked or unlocked state of the locking / unlocking unit.

[0025] In the entry and exit management device of the present invention, the control unit executes the lock / unlock determination process when it determines that the person has exited from the space on the first area side to the space on the second area side.

[0026] This allows the locking / unlocking state of the locking / unlocking section to be notified when a person leaves the room.

[0027] In the entry and exit management device of the present invention, the control unit executes the lock / unlock determination process when it determines that the person has entered from a space on the second area side to a space on the first area side.

[0028] This allows the locking / unlocking state of the locking / unlocking section to be notified when a person enters the room.

[0029] In the entrance and exit control device according to the present invention, the opening and closing detection unit, the human detection unit, and the control unit are accommodated in the same housing.

[0030] This makes it possible to easily install the entrance and exit control device at the opening and closing section.

[0031] In the entry / exit management device of the present invention, the lock / unlock detection unit is housed in a housing different from the housing in which the human detection unit, the open / close detection unit, and the control unit are housed.

[0032] This makes it possible to easily install an entrance / exit management device having a lock / unlock monitoring function at a door.

[0033] In the entry / exit management device of the present invention, the housing that houses the lock / unlock detection unit is characterized in that it can be removed from the housing that houses the human detection unit, the open / close detection unit, and the control unit.

[0034] This makes it possible to easily install the human detection unit, open / close detection unit, and lock / unlock detection unit separately in an appropriate manner for each.

[0035] The entrance / exit management device according to the present invention further includes an operation unit that acquires an operation from outside; The control unit switches the detection states of the human detection unit, the open / close detection unit, and the lock / unlock detection unit in response to the external operation acquired via the operation unit.

[0036] This makes it possible to easily switch the detection state of each detection unit by external operation. [Brief description of the drawings]

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. EXAMPLES

[0039] An entrance / exit control device according to the present invention will be described below by taking an entrance / exit control device 100 as an example of an embodiment.

[0040] 1. Overview of the entrance and exit management device 100 As shown in FIG. 1, the entrance and exit control device 100 controls the entrance and exit of people by monitoring the presence of people around a door D, which is an opening and closing part, and the open and closed states of the door D.

[0041] Second Configuration of the Entrance and Exit Management Device 100 The configuration of the entrance and exit control device 100 will be described with reference to Fig. 1. The entrance and exit control device 100 has a human detection unit 101, an opening / closing detection unit 103, and a control unit 107.

[0042] The human detection unit 101 is a so-called human sensor that detects the presence of a human in a predetermined detection area using infrared rays. As shown in FIG. 2, in the entrance and exit management device 100, the human detection units 101 are arranged adjacent to the door D and facing each other with the door D as a boundary, and form a human detection area R101 that projects detection light such as infrared light on one side of a first passing area RP1 and a second passing area RP2 through which people pass. In FIG. 2, the first passing area RP1 side is set on the inside side, and the human detection unit 101 forms the human detection area R101 on the first passing area side on the inside side. The human detection unit 101 is arranged on the ceiling and forms the human detection area R101 along the vertical direction.

[0043] 1, the open / close detection unit 103 has a frame arrangement unit 103a and a door arrangement unit 103b. The frame arrangement unit 103a is arranged on a door frame F of the door D. The door arrangement unit 103b is arranged on the door D so as to face the frame arrangement unit 101a. The frame arrangement unit 103a detects the open / closed state of the door D, which is the opening / closing unit, by detecting the magnetic force between itself and the door arrangement unit 103b.

[0044] The hardware configuration of the frame arrangement unit 103a of the open / close detection unit 103 is shown in FIG. 15. The frame arrangement unit 103a has a magnetic force detection unit 103a1, a magnetic force detection control unit 103a2, and an interface unit 103a3. The magnetic force detection unit 103a1 detects the magnetic force generated by the door arrangement unit 103b (see FIG. 1) installed opposite to itself on the door D, which is the open / close unit, for example, the magnetic force generated by the magnet of the door arrangement unit 103b. The magnetic force detection control unit 103a2 judges the magnetic force detected by the magnetic force detection unit 103a1, and transmits open / close detection information indicating the same to the control unit 107 via the interface unit 103a3. For example, when the magnetic force detection control unit 103a2 detects a magnetic force larger than a predetermined magnitude, it judges that "the door D is in a closed state", and on the other hand, when it detects a magnetic force smaller than the predetermined magnitude, it judges that "the door D is in an open state".

[0045] The configuration of the control unit 107 will be described with reference to Fig. 4. The control unit 107 includes a CPU 107a, a memory 107b, an interface unit 107c, a communication unit 107d, and a power supply unit 107h.

[0046] The CPU 107a performs processing based on an operating system (OS), firmware, an entrance / exit management program, and other applications recorded in the memory 107b. The memory 107b provides a working area for the CPU 107a. The memory 107b records and holds the OS, the entrance / exit management program, and other applications, as well as various data.

[0047] The interface unit 107c is connected to the human detection unit 101 and the open / close detection unit 103. The CPU 107a acquires predetermined information from the human detection unit 101 and the open / close detection unit 103 via the interface unit 107c.

[0048] The communication unit 107d communicates with a predetermined communication device such as a cloud server using wireless LAN technology, and transmits and receives various information such as data on people entering and leaving the room.

[0049] The power supply unit 107h has a power supply such as a button battery, etc. The power supply unit 107h supplies a predetermined amount of power to each component.

[0050] Third, operation of control unit 107

[0051] The entrance / exit management process executed by the CPU 107a of the control unit 107 will be described with reference to FIGS.

[0052] 1. Overview of Entrance and Exit Management Processing An overview of the entrance and exit management process will be described with reference to Fig. 5. The entrance and exit management device 100 manages the entrance and exit of people using the detection of people by the person detection unit 101 and the order of opening and closing of the door D by the open / close detection unit 103.

[0053] As shown in FIG. 5A, when the human detection unit 101 is formed in the first passage area RP1, the human detection unit 101 reacts first when a person moves from the first passage area RP1 side toward the door D. After that, the person opens the door D, that is, opens the door D, so the open / close detection unit 103 detects the door D from its closed state to its open state. Then, when the person passes through the door D from the first passage area RP1 toward the second passage area RP2 and closes the door D, the open / close detection unit 103 detects the door D from its open state to its closed state. If nothing is detected by the human detection unit 101 or the open / close detection unit 103 after that, it can be determined that the person has left the room. This case corresponds to, for example, a case where a person goes out.

[0054] 5B, if the human detection unit 101 first detects a person, then the open / close detection unit 103 detects door D changing from a closed state to an open state, and then the open / close detection unit 103 detects door D changing from an open state to a closed state, and then the human detection unit 101 detects a person, it can be determined that the person has opened and closed door D and then re-entered. This case corresponds to, for example, a case in which a person is responding to a visitor near door D.

[0055] Furthermore, as shown in FIG. 5C, when the human detection unit 101 is formed in the first passage area RP1, when a person approaches the door D from the second passage area RP2 side, the person first opens the door D, that is, opens the door D, and the open / close detection unit 103 detects the door D from its closed state to its open state. Then, when the person passes through the door D from the second passage area RP2 to the first passage area RP1 and closes the door D, the open / close detection unit 103 detects the door D from its open state to its closed state. If the human detection unit 101 detects a person thereafter, it can be determined that the person has entered the first passage area RP1 side from the second passage area RP2 side. This case corresponds to, for example, a case where a person is returning home.

[0056] 2. Entrance and exit management processing The entrance / exit management process executed by the CPU 107a of the control unit 107 based on the entrance / exit management program stored in the memory 107b will be described with reference to the flowcharts of FIG. 6 and FIG.

[0057] 6, when the power is turned on, the CPU 107a transmits human detection start information to the human detection unit 101 and open / close detection start information to the open / close detection unit 103 (S701), and operates the human detection unit 101 and the open / close detection unit 103. Then, the CPU 107a enters a state of waiting for acquisition of human detection status information from the human detection unit 101 and open / close detection status information from the open / close detection unit 103 (S703, S805 (see FIG. 7)).

[0058] When the human detection unit 101 acquires the human detection start information, it detects the presence of a person in a predetermined human detection range using infrared rays, etc. When the human detection unit 101 detects a person, it transmits the person detection status information to the control unit 107.

[0059] Furthermore, when the open / close detection unit 103 acquires the open / close detection start information, the magnetic force detection control unit 103a2 of the frame arrangement unit 103a executes an open / close state determination process to determine whether the door D is open or closed. When the magnetic force detection control unit 103a2 acquires the magnitude of the magnetic force via the magnetic force detection unit 103a1, it determines whether the door D is open or closed based on the magnetic force. For example, if the magnetic force is greater than a predetermined value, the magnetic force detection control unit 103a2 determines that the door D is in a closed state, and if the magnetic force is less than the predetermined value, it determines that the door D is in an open state. The magnetic force detection control unit 103a2 transmits the determined state of the door D as open / close detection state information to the control unit 107 via the interface unit 103a3.

[0060] When the CPU 107a acquires human detection state information from the human detection unit 101 before acquiring the open / close detection state information from the open / close detection unit 103 (S703), the CPU 107a enters a state of waiting for acquisition of the open / close detection state information from the open / close detection unit 103 (S705). When the CPU 107a acquires an open / close detection state indicating "open information" of the door D from the open / close detection unit 103 (S705), the CPU 107a temporarily disables detection by the human detection unit 101 (S707). Then, the CPU 107a enters a state of waiting for acquisition of the open / close detection state information from the open / close detection unit 103 (S709).

[0061] Thereafter, when the CPU 107a acquires an opening / closing detection status indicating "closed information" for door D from the opening / closing detection unit 103 (S709), it enables detection by the human detection unit 101 (S711) and enters a state of waiting for acquisition of human detection status information from the human detection unit 101 (S713).

[0062] When the CPU 107a acquires human detection state information from the human detection unit 101 (S713), it determines that the person detected in step S703 opened the door D, closed it, and returned inside the room, that is, did not leave the room (S715).

[0063] Furthermore, if the CPU 107a determines that a predetermined time has elapsed without acquiring person detection status information after acquiring open / close detection status information indicating the closed state of door D in step S709 (S713, S717), it determines that the person detected in step S703 opened and closed door D and then left the room (S719).

[0064] In addition, if the CPU 107a determines that a predetermined time has elapsed without acquiring open / close detection state information indicating the closed state of the door D after acquiring the person detection state information in step S703 (S705, S721), the CPU 107a determines that the person detected in step S703 did not open or close the door D, and therefore did not leave the room (S715).

[0065] 8, when the CPU 107a acquires open / close detection state information indicating the “open state” of the door D from the open / close detection unit 103 before acquiring the human detection state information from the human detection unit 101 (S805), the CPU 107a temporarily disables detection by the human detection unit 101 (S807). Then, the CPU 107a enters a state of waiting for acquisition of the open / close detection state information from the open / close detection unit 103.

[0066] Thereafter, when the CPU 107a acquires an opening / closing detection status indicating “closed information” for door D from the opening / closing detection unit 103 (S809), it enables detection by the human detection unit 101 (S811) and enters a state of waiting for acquisition of human detection status information from the human detection unit 101.

[0067] When the CPU 107a acquires human detection state information from the human detection unit 101 (S813), it determines that the person detected in step S813 opened and closed the door D and then entered the room (S815).

[0068] Furthermore, if the CPU 107a determines that a predetermined time has elapsed without acquiring person detection state information after acquiring open / close detection state information indicating the "closed state" of door D in step S809 (S813, S817), it determines that the person who opened door D in step S805 closed door D and did not enter the room (S819).

[0069] As shown in FIG. 7, the CPU 107a repeats the processes of steps S701 to S819 until the operation ends (S723).

[0070] In this manner, in the entrance and exit management device 100, by simply using the human detection unit 101 and the open / close detection unit 103, it is possible to easily manage the entrance and exit of people.

[0071] Also, entry and exit can be managed simply by installing the human detection unit 101 so as to monitor an area on one side of the door D, which is an opening and closing part, as a boundary. EXAMPLES

[0072] The entrance / exit control device 100 according to the first embodiment described above uses the human detection unit 101 and the open / close detection unit 103 to control the entrance / exit of people. On the other hand, the entrance / exit control device 200, which is another embodiment of the entrance / exit control device according to the present invention, also uses a lock / unlock detection unit 205 that detects the locked / unlocked state of the locking / unlocking device of the door D to control the entrance / exit of people. In the following, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0073] First, configuration of the entrance and exit management device 200 As shown in FIG. 8, the entrance and exit control device 200 includes a human detection unit 101, an open / close detection unit 103, a lock / unlock detection unit 205, and a control unit 207.

[0074] 1. Configuration of the lock / unlock detection unit 205 The lock / unlock detection unit 205 monitors the locked / unlocked state of the lock / unlock device L attached to the door D, which is the opening and closing part. The lock / unlock detection unit 205 is installed at a position a predetermined distance away from the door D on a wall W that is arranged perpendicular to the door D.

[0075] In addition, the lock / unlock detection unit 205 projects a predetermined detection light from its installation position toward the locking / unlocking device L diagonally from the front in Figure 8, receives reflected light from the locking / unlocking device L, and monitors the locked / unlocked state of the locking / unlocking device L.

[0076] In addition, in Figure 8, the locking / unlocking device L monitored by the locking / unlocking detection unit 205 has a handle portion LH, which is a throne that operates the latch when grasped and turned, and a thumb turn LS, which is located on the handle portion LH and is an operating part that operates the deadbolt.

[0077] The thumb turn LS changes its state between a locked state (see FIG. 12) and an unlocked state (see FIG. 13) within an operating part movement range formed by rotation around a predetermined axis. The user operates the thumb turn LS to change the state, thereby switching the locking / unlocking device L between the locked state and the unlocked state.

[0078] This makes it possible to easily monitor the locking and unlocking states and network the devices without modifying the locking and unlocking devices that are already installed.

[0079] The configuration of the locking / unlocking detection unit 205 will be described with reference to Fig. 9, which is a perspective view of the locking / unlocking detection unit 205. The locking / unlocking detection unit 205 has a housing unit 2051, a detection unit 2053, a notification transmission communication unit 2055, a control unit 2057, and an angle adjustment unit 2059. The housing unit 2051 accommodates the detection unit 2053, the notification transmission communication unit 2055, and the control unit 2057 inside. The housing unit 2051 also has a light projection / reception opening A2051 so that a light projection unit 2053a of the detection unit 2053 (described later) arranged inside can project detection light toward the outside, and so that a light reception unit 2053b (described later) can receive reflected light of the detection light from the outside.

[0080] The detection unit 2053 is configured using a distance measuring area image sensor using the TOF (Time-Of-Flight) method. The detection unit 2053 projects near-infrared laser light, which is detection light, into a state change range ALS (described later) in which the state of the thumb turn LS of the locking / unlocking device L changes between an unlocked state and a locked state, and measures the distance to the thumb turn LS.

[0081] The hardware configuration of the detection unit 2053 is shown in FIG. 10. The detection unit 2053 has a light projecting unit 2053a, a light receiving unit 2053b, a detection control unit 2053c, and an interface unit 2053d. The light projecting unit 2053a projects red laser light, which is detection light. The light receiving unit 2053b is composed of a light receiving lens that receives and collects reflected light of the detection light, and photodiodes arranged in a two-dimensional matrix. Each of the photodiodes arranged in the two-dimensional matrix forms a partial light receiving area, and one detection area is formed as a collection of the partial light receiving areas.

[0082] The detection control unit 2053c controls the timing of light projection and reception by the light projection unit 2053a and the light reception unit 2053b. The detection control unit 2053c also measures the time from projecting the detection light to receiving the reflected light of the detection light, and calculates the distance to the object that reflected the detection light. Furthermore, the detection control unit 2053c transmits the calculated distance to the control unit 2057 as detection information.

[0083] The configuration of the control unit 207 will be described with reference to Fig. 11. The control unit 207 has a CPU 107a, a memory 207b, an interface unit 207c, a notification transmission communication unit 207d, an alarm sound generating unit 207e, and a power supply unit 107h.

[0084] The CPU 107a performs processing based on an operating system (OS) or firmware, and other applications such as an entrance / exit management program related to the entrance / exit management device 200, which are recorded in the memory 207b. The memory 207b provides a working area for the CPU 107a. The memory 207b records and holds the OS or firmware, and other applications such as an entrance / exit management program related to the entrance / exit management device 200, and various data.

[0085] The interface unit 207c is connected to the human detection unit 101, the open / close detection unit 103, and the lock / unlock detection unit 205. The CPU 107a transmits and receives predetermined information to and from each component via the interface unit 207c.

[0086] The warning sound generating unit 207e generates a predetermined warning sound.

[0087] The notification transmission communication unit 207d connects to a predetermined communication device (not shown) such as a cloud server to transmit information regarding entry and exit, and connects to a predetermined communication terminal HP to transmit lock / unlock information indicating the locking and unlocking states of the locking / unlocking device L. The notification transmission communication unit 207d connects to the communication terminal HP, etc., via a wireless communication device in the room where the door D is located, using, for example, wireless LAN (Local Area Network) technology. Note that an address that uniquely identifies the notification transmission communication unit 207d, such as a MAC address or an IP address, is set in advance.

[0088] The power supply unit 107h has a power supply such as a button battery housed therein, and supplies a predetermined amount of power to each of the components.

[0089] 9, the angle adjustment unit 2059 adjusts the angle of the light projecting and receiving opening A2051 of the housing unit 2051 with respect to the detection target, that is, the angle of the detection light projected by the light projecting unit 2053a and the angle of the reflected light received by the light receiving unit 2053b. The angle adjustment unit 109 has a triangular prism shape and is disposed along the back surface of the housing unit 2051. By using the angle adjustment unit 2059 that adjusts the angle between the housing unit 2051 of the entry and exit management device 100 and the wall W, the detection area can be appropriately set.

[0090] Operation of the third control unit 2057 1. Overview An overview of the locking / unlocking determination process in the control unit 2057 will be described with reference to Fig. 12 and Fig. 13. Fig. 12 shows the detection state of the locking / unlocking device L in the locked state as seen by the locking / unlocking detection unit 205. Similarly, Fig. 13 shows the detection state of the locking / unlocking device L in the unlocked state as seen by the locking / unlocking detection unit 205.

[0091] Here, the detection control unit 2053c of the detection unit 2053 of the locking / unlocking detection unit 205 projects detection light through the light projecting unit 2053a to a detection area A2053 including a state change range ALS, which is a range in which the thumb turn LS of the locking / unlocking device L operates. The detection control unit 2053c receives reflected light of the projected detection light through the light receiving unit 2053b. The light receiving unit 2053b has partial light receiving areas divided into 10×10. The detection control unit 2053c calculates the time from light projection to light reception for each partial light receiving area, and then calculates the distance to a reflecting object using the calculated time. Note that each partial light receiving area of ​​the light receiving unit 2053b corresponds to a partial detection area A2053[x, y] (x is the value on the horizontal axis, y is the value on the vertical axis, and x and y are natural numbers from 1 to 10) obtained by dividing the detection area A2053 into 10×10.

[0092] As shown in FIG. 12, when the locking / unlocking device L is in the locked state, the thumb turn LS is present in the partial detection area A2053[2,5] to A2053[7,5], and therefore the distance to the reflective object calculated by the detection unit 2053 for the partial detection area A2053[2,5] to A2053[7,5] is smaller than the values ​​for the other partial detection areas.

[0093] On the other hand, as shown in FIG. 13, when the locking / unlocking device L is in the unlocked state, the thumb turn LS is present in the partial detection areas A2053[4,3] to A2053[4,7] and A2053[5,3] to A2053[5,7], so the distance to the reflective object calculated by the detection unit 2053 is smaller in the partial detection areas A2053[4,3] to A2053[4,7] and A2053[5,3] to A2053[5,7] than in the other partial detection areas.

[0094] Therefore, the distance values ​​change significantly between the locked and unlocked states of the locking / unlocking device L in the partial detection areas A2053[2,5] to A2053[3,5], A2053[4,3] to A2053[4,4], A2053[5,3] to A2053[5,4], A2053[6,5] to A2053[7,5], A2053[4,6] to A2053[4,7], and A2053[5,6] to A2053[5,7].

[0095] After installing the lock / unlock detection unit 205 in the control unit 2057, the user calculates the distance to each partial detection area in the locked state and the unlocked state of the locking / unlocking device L during setup, and stores and holds in the memory 2057b the partial detection area between which the distance changes significantly. The user also stores and holds in the control unit 2057 the values ​​of the target partial detection area in the locked state and the unlocked state as reference locked state information and reference unlocked state information, respectively.

[0096] When the control unit 2057 acquires received light information from the detection unit 2053, it extracts the distance value of the target portion detection area and compares it with the reference locked state information and the reference unlocked state information to determine whether the locking / unlocking device L is in a locked state or an unlocked state.

[0097] Operation of the third control unit 207 1. Overview of lock / unlock decisions An overview of the locking / unlocking determination process in the control unit 207 will be described with reference to Fig. 15 and Fig. 16. Fig. 15 shows the detection state of the locking / unlocking device L in the locked state as seen by the entry / exit control device 200. Similarly, Fig. 16 shows the detection state of the locking / unlocking device L in the unlocked state as seen by the entry / exit control device 200.

[0098] Here, the detection control unit 2053c of the locking / unlocking detection unit 205 of the entry / exit management device 200 projects detection light via the light projecting unit 2053a to a detection area A2053 including a state change range ALS, which is a range in which the thumb turn LS of the locking / unlocking device L operates. The detection control unit 2053c receives reflected light of the projected detection light via the light receiving unit 2053b. The light receiving unit 2053b has partial light receiving areas divided into 10×10. The detection control unit 2053c calculates the time from light projection to light reception for each partial light receiving area, and then calculates the distance to the reflective object using the calculated time. Each partial light receiving area of ​​the light receiving unit 2053b corresponds to a partial detection area A2053[x, y] (x is the horizontal axis value, y is the vertical axis value, and x and y are natural numbers from 1 to 10) obtained by dividing the detection area A2053 into 10×10 areas.

[0099] As shown in FIG. 12, when the locking / unlocking device L is in the locked state, the thumb turn LS is present in the partial detection area A2053[2,5] to A2053[7,5], so the distance to the reflective object calculated by the locking / unlocking detection unit 205 is smaller for the partial detection area A2053[2,5] to A2053[7,5] than for the other partial detection areas.

[0100] On the other hand, as shown in FIG. 13, when the locking / unlocking device L is in the unlocked state, the thumb turn LS is present in the partial detection areas A2053[4,3] to A2053[4,7] and A2053[5,3] to A2053[5,7], so the distance to the reflective object calculated by the locking / unlocking detection unit 205 for the partial detection areas A2053[4,3] to A2053[4,7] and A2053[5,3] to A2053[5,7] is smaller than the values ​​for the other partial detection areas.

[0101] Therefore, the distance values ​​change significantly between the locked and unlocked states of the locking / unlocking device L in the partial detection areas A2053[2,5] to A2053[3,5], A2053[4,3] to A2053[4,4], A2053[5,3] to A2053[5,4], A2053[6,5] to A2053[7,5], A2053[4,6] to A2053[4,7], and A2053[5,6] to A2053[5,7].

[0102] After installing the entry / exit management device 200, the user calculates the distance to each partial detection area in the locked state and the unlocked state of the locking / unlocking device L during setup in the control unit 207, and stores and retains in the memory 207b the partial detection area between which the distance changes significantly. The user also stores and retains in the control unit 207 the values ​​of the target partial detection area in the locked state and the unlocked state as reference locked state information and reference unlocked state information, respectively.

[0103] When the control unit 207 acquires light reception information from the lock / unlock detection unit 205, it extracts the distance value of the target portion detection area, compares it with the reference locked state information and the reference unlocked state information, and determines whether the lock / unlock device L is in a locked state or an unlocked state.

[0104] 2. Entrance and exit management processing The entrance / exit management process executed by the CPU 107a of the control unit 207 will be described with reference to the flowcharts shown in FIGS.

[0105] 14, when the CPU 107a acquires an open / close detection state indicating "open information" of the door D from the open / close detection unit 103 in step S705, it determines that the door D has changed from a closed state to an open state, and generates an open / close unit open warning sound to warn that the door D has changed to an open state (S1401). After that, the CPU 107a temporarily disables detection by the human detection unit 101 (S707).

[0106] Furthermore, when the CPU 107a acquires the human detection state information from the human detection unit 101 in step S713, the CPU 107a executes a lock / unlock monitoring process (S1403). The lock / unlock monitoring process will be described later. The CPU 107a then determines that the person detected in step S703 once opened the door D, closed it, and returned inside the room, that is, did not leave the room (S715).

[0107] Furthermore, if the CPU 107a determines in step S717 that a predetermined time has elapsed without acquiring human detection state information after acquiring open / close detection state information indicating the closed state of the door D, the CPU 107a executes a lock / unlock monitoring process (S1405).Then, the CPU 107a determines that the person detected in step S703 opened and closed the door D and then left the room (S719).

[0108] 15, in step S805, when the CPU 107a acquires from the open / close detection unit 103 information indicating the "open state" of the door D before acquiring the human detection state information from the human detection unit 101, the CPU 107a generates an open / close unit warning sound to warn that the door D is now in the open state (S1501). After that, the CPU 107a temporarily disables the detection by the human detection unit 101 (S807).

[0109] Furthermore, in step S813, the CPU 107a executes a lock / unlock monitoring process (S1503) when acquiring human detection state information from the human detection unit 101. Then, the CPU 107a determines that the person detected in step S813 opened and closed the door D and then entered the room (S815).

[0110] Furthermore, if the CPU 107a determines in step S817 that a predetermined time has elapsed without acquiring human detection state information after acquiring open / close detection state information indicating the closed state of the door D, the CPU 107a executes a lock / unlock monitoring process (S1505).Then, the CPU 107a determines that the person who opened the door D in step S805 closed the door D and did not enter the room (S819).

[0111] Here, the lock / unlock monitoring process in steps S1403, S1405, S1503, and S1505 will be described with reference to Fig. 16. The CPU 107a starts timing the unlocked state time (S1603). The CPU 107a also transmits lock / unlock detection start information to the lock / unlock detection unit 205 to determine the locked / unlocked state of the thumb turn LS (S1603). The CPU 107a then enters a state of waiting for acquisition of locked / unlocked state information from the lock / unlock detection unit 205 (S1605).

[0112] When the lock / unlock detection unit 205 acquires the lock / unlock detection start information, it projects detection light from the light projecting unit 2053a onto the detection area A2053. When the lock / unlock detection unit 205 receives the reflected light of the projected detection light with the light receiving unit 2053b, it calculates the distance to the object that reflected the detection light from the time from when the light was projected to when the light was received for each partial light receiving area of ​​the light receiving unit 2053b. When the lock / unlock detection unit 2053 finishes calculating the distance for all partial light receiving detection areas, it transmits lock / unlock detection information to the control unit 207, in which the calculated distance for each partial light receiving area is set as the distance for the corresponding partial detection area A2053[x,y].

[0113] When the CPU 107a acquires the lock / unlock state information in step S1605, it judges whether or not the lock / unlock device L is in a locked state (S1607). The CPU 107a judges whether or not the lock / unlock device L is in a locked state based on a lock / unlock judgment process. The lock / unlock judgment process will be described later.

[0114] When the CPU 107a determines in step S1607 that the locking / unlocking device L is in the locked state, it generates a locking completion sound indicating that the locking / unlocking device L has been locked (S1609).

[0115] If the CPU 107a determines in step S1607 that the locking / unlocking device L is not in a locked state, that is, in an unlocked state, it determines whether or not the unlocked state time has elapsed a predetermined time (S1611). The predetermined time is set to, for example, one minute.

[0116] When the CPU 107a judges that the unlocked state time has elapsed the predetermined time, it judges that the unlocked state continues for the unlocked state time or more, and generates an unlocked state warning sound (S1613). In addition, the CPU 107a transmits lock / unlock information indicating that the unlocked state of the locking / unlocking device L continues to be in the unlocked state to a predetermined communication terminal HP via the notification transmission communication unit 207d (S1615).

[0117] Here, the locking / unlocking determination process in the entry / exit management device 200 will be described with reference to Fig. 17. The CPU 107a acquires reference locking state information and reference unlocking state information from the memory 107b (S1701). The CPU 107a determines whether the acquired values ​​of each target portion detection area match or are similar to the reference locking state information (S1703). If the CPU 107a determines that the acquired values ​​of each target portion detection area match or are similar to the reference locking state information, it determines that the locking / unlocking device L is in a locked state (S1705).

[0118] The CPU 107a judges whether the acquired value of each target portion detection area matches or is similar to the reference unlocked state information (S1707). If the CPU 107a judges that the acquired value of each target portion detection area matches or is similar to the reference unlocked state information, it judges that the locking / unlocking device L is in the unlocked state (S1709).

[0119] In this manner, the entry and exit control device 200 can easily determine the locked or unlocked state of the lock / unlock unit.

[0120] In addition, when a person leaves a room, the locked / unlocked state of the locking / unlocking unit can be easily notified.In addition, when a person enters a room, the locked / unlocked state of the locking / unlocking unit can be easily notified. EXAMPLES

[0121] The entrance and exit control device 100 according to the first embodiment described above manages the entrance and exit of people using the human detection unit 101, the open / close detection unit 103, and the control unit 107, which are independent of each other. On the other hand, the entrance and exit control device according to the present invention easily manages the entrance and exit of people using the entrance and exit control device 300 which integrates the human detection unit 301, the open / close detection unit 303, and the control unit 307. In the following, the same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0122] First, an overview of the entrance and exit management device 300 18, the entrance and exit control device 300 controls the entrance and exit of people who are passing through door D, which is an opening and closing section. The entrance and exit control device 300 is installed on a predetermined surface of the door D, at a predetermined distance away from the door frame F of the door D. The entrance and exit control device 300 is disposed parallel to the door frame F.

[0123] Further, a magnet M is disposed on the door frame F at a position corresponding to the open / close detection unit 303 of the entry / exit control device 300. Note that the magnet M is disposed on the door frame F by the magnetic force of the magnet M if the door frame F is made of metal, or by using an adhesive such as double-sided tape. Note that the magnet M corresponds to the door arrangement unit 103b of the open / close detection unit 103 in the entry / exit control device 100.

[0124] This makes it possible to easily manage people's entry and exit by simply installing the entry and exit management device 300.

[0125] Second Configuration of the Entrance and Exit Management Device 300 The configuration of the entrance and exit control device 300 will be described with reference to FIG. 19, which is a perspective view of the entrance and exit control device 300. The entrance and exit control device 300 has a human detection unit 301, an open / close detection unit 303, a control unit 307, and a housing unit 309.

[0126] The housing unit 309 accommodates the human detection unit 301, the open / close detection unit 303, and the control unit 307 inside. The housing unit 309 has a rectangular parallelepiped shape. The housing unit 309 has an attachment surface P309B for attaching the housing unit 309 to a predetermined position, such as a predetermined surface of the door D. The housing unit 309 has a human detection opening A309 on a surface P309F located opposite the attachment surface P309B.

[0127] The human detection unit 301 has a similar configuration to the human detection unit 101 of the entrance and exit control device 100. The human detection unit 301 projects detection light for human detection through a human detection opening A309 of a housing unit 309 and receives reflected light. In Fig. 18, the human detection unit 301 is disposed on one side of the door D, and therefore forms a human detection region R301 of the human detection unit 301 along a direction perpendicular to the door D on the first passing region side on the inside side.

[0128] The open / close detection unit 303 has the same configuration as the frame arrangement unit 103a of the open / close detection unit 103 of the entry / exit management device 100 (see FIG. 3). The open / close detection unit 303 is arranged corresponding to the surface P309S perpendicular to the mounting surface P309B of the housing unit 309 and the surface (not shown) facing the surface P309S so as to detect magnetic force from the surface P309S toward the outside, and the surface facing the surface P309S. This allows an appropriate mounting position to be selected depending on the specifications of the door D, such as the opening direction of the door D, the position of the handle, and the position of the thumb turn LS.

[0129] The configuration of the control unit 307 will be described with reference to Fig. 20. The control unit 307 has a CPU 107a, a memory 307b, an interface unit 207c, a notification transmission communication unit 207d, a power supply unit 107h, and an operation unit 307f.

[0130] The CPU 107a performs processing based on an operating system (OS) or firmware recorded in the memory 307b, and other applications such as an entrance / exit management program related to the entrance / exit management device 300. The memory 307b provides a working area for the CPU 107a. The memory 207b records and holds the OS or firmware, and other applications such as an entrance / exit management program related to the entrance / exit management device 300, and various data.

[0131] The operation unit 307f receives input from the outside. The user can perform predetermined settings on the control unit 307 by operating the operation unit 307f.

[0132] In this way, by forming the entrance / exit control device 300 by integrating a plurality of components, the entrance / exit control device 300 can be easily installed.

[0133] Third, installation of the entrance / exit management device 300 The installation of the entry and exit control device 300 will be described with reference to Fig. 18. The user places the entry and exit control device 300 so that the mounting surface P309B of the housing part 309 of the entry and exit control device 300 is along one side of the door D to which it is to be attached, and so that the surface P309S of the housing part 309 is along the side edge of the door D, that is, along the door frame F. Note that a predetermined gap is left between the door D and the surface P309S of the housing part 309 so that a magnet M that generates a magnetic force can be placed.

[0134] The user fixes the position of the housing unit 309. Each part is fixed using double-sided tape or a predetermined fixing screw.

[0135] In this way, by forming the entrance / exit control device 300 by integrating a plurality of components, the entrance / exit control device 300 can be easily installed. EXAMPLES

[0136] The entrance / exit control device 200 according to the second embodiment described above controls the entrance / exit of people using the human detection unit 101, the open / close detection unit 103, the lock / unlock detection unit 205, and the control unit 207, which are independent of each other. On the other hand, the entrance / exit control device according to the present invention uses the entrance / exit control device 400, which integrates the human detection unit 301, the open / close detection unit 303, the lock / unlock detection unit 405, and the control unit 407, to easily control the entrance / exit of people and the lock / unlock state of the lock / unlock device L. In the following, the same components as those in the first to third embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0137] First, an overview of the entrance and exit management device 400 21, the entrance / exit control device 400 controls the entrance / exit of people passing through door D, which is an opening / closing section, and also monitors the locking / unlocking state of a locking / unlocking device L arranged on the door D. The entrance / exit control device 400 is installed on a predetermined surface of the door D, at a predetermined distance from the door frame F of the door D. The entrance / exit control device 300 is arranged parallel to the door frame F.

[0138] In addition, the locking / unlocking detection unit 405 (see Figure 22) of the entry / exit management device 400 projects a predetermined detection light from its installation position toward the locking / unlocking device L diagonally from the front (Figure 21), receives the reflected light from the locking / unlocking device L, and monitors the locked / unlocked state of the locking / unlocking device L.

[0139] In this way, by forming the entrance / exit control device 400 by integrating a plurality of components, the entrance / exit control device 400 can be easily installed.

[0140] Second Configuration of Entrance and Exit Management Device 400 The configuration of the entrance and exit control device 400 will be described with reference to FIG. 22, which is a perspective view of the entrance and exit control device 400. The entrance and exit control device 400 has a human detection unit 301, an open / close detection unit 303, a lock / unlock detection unit 405, a control unit 407, and a housing unit 409.

[0141] The housing unit 401 has a main housing unit 409a and a lock / unlock detection housing unit 409b. The main housing unit 409a has the same configuration as the housing unit 309 in the entry / exit management device 300, except for a connection structure (described later) that connects the lock / unlock detection unit 405. The main housing unit 409a houses the human detection unit 301, the open / close detection unit 303, and the control unit 407 inside.

[0142] The locking / unlocking detection housing 409b is disposed at one end of the main housing 409a. The locking / unlocking detection housing 409b has a first detection direction adjustment housing 409b1 and a second detection direction adjustment housing 409b3. The first detection direction adjustment housing 409b1 has a rectangular parallelepiped shape with a semi-cylindrical shape at one end. The first detection direction adjustment housing 409b1 has a rotation axis J409b1 perpendicular to the mounting surface P309B. The first detection direction adjustment housing 409b1 is attached to the main housing 409a so as to be rotatable about the rotation axis J409b1. This allows the detection range A2053 of the detection light of the locking / unlocking detection unit 405 to be rotated and adjusted about the rotation axis J409b1 (see FIG. 21).

[0143] The second detection direction adjustment housing part 409b3 is attached so as to be housed in one end of the first detection direction adjustment housing part 409b1. The second detection direction adjustment housing part 409b3 is attached to the main housing part 409a so as to be rotatable about the rotation axis J409b3 relative to the main housing part 409a. This allows the detection range A2053 of the detection light of the lock / unlock detection part 405 to be rotated and adjusted about the rotation axis J409b3.

[0144] The second detection direction adjustment housing part 409b3 houses therein a light projecting part 2053a and a light receiving part 2053b (see FIG. 10) of a detection part 2053 of a lock / unlock detection part 405 (described later). The second detection direction adjustment housing part 409b3 is configured so that the light projecting part 2053a of the lock / unlock detection part 405 arranged therein can project detection light toward the outside from an end face P409b3, and so that the light receiving part 2053b can receive reflected light of the detection light from the outside.

[0145] The lock / unlock detection unit 405 has a similar configuration to the detection unit 2053 of the lock / unlock detection unit 205 of the entry / exit management device 200 (see FIG. 10).

[0146] The configuration of the control unit 407 will be described with reference to Fig. 23. The control unit 407 has a CPU 107a, a memory 407b, an interface unit 207c, a notification transmission communication unit 207d, an alarm sound generating unit 207e, a power supply unit 107h, and an operation unit 307f.
