Description

  The present invention relates to an entry / exit detection device that can reliably detect a state of entering and exiting a living room with a simple configuration.

  2. Description of the Related Art In recent years, in many accommodation facilities such as hotels, internal electric devices and electronic devices are operated in accordance with stays of guests. This is because, in a case where the guest is absent, unnecessary electrical and electronic devices and electronic devices are put into a stopped state or a standby state, thereby realizing a reduction in electricity costs and a reduction in global environmental load.

  Similarly, when the guest enters the room, it is also preferable to activate necessary electric and electronic devices without bothering the guest. This is because the service level to the guest can be improved. In addition, in accommodation facilities, there are many foreign guests, and the operation of the electric and electronic devices provided in the room may not be immediately understood. Also in this case, it is convenient for the guest that these are automatically activated when entering the room.

  For the same reason, when the guest leaves the room, it is preferable that the operation of electric devices and electronic devices such as lighting fixtures, air conditioners, and televisions be stopped. This is because, as described above, the reduction of the electricity rate and the reduction of the burden on the global environment are realized. Hotel guests are often in a hurry when leaving a room. This is because they are distracted by going out for business. Also, unlike their own homes, their awareness of stopping electrical and electronic devices is low. This is even more so for foreign guests, whose operation of electrical and electronic devices is difficult to understand linguistically.

  From such a viewpoint, it is also preferable that the electrical equipment and the electronic device automatically stop when the guest leaves the room.

  When such a guest enters the room, the electric equipment or electronic device starts up, and when the guest leaves the room, the electric device or electronic device stops, which is a cost, global environment, guest benefit, accommodation facility. It is suitable in various aspects such as convenience. In particular, it is preferable that the start according to the entry and the stop according to the exit are automatically performed.

  At present, for example, a guest entering a room is determined by inserting a card key or the like used for entering a living room into an insertion case near an entrance. Based on the entry determination, electric devices and electronic devices such as a lighting device and an air conditioner are activated. Alternatively, when the card key is removed from the insertion case, it is considered that the guest has left the room, and the electric and electronic devices are stopped. As described above, the entry and exit of the room are electronically grasped by the operation of the guest, and the electric device and the electronic device are automatically started and stopped.

  However, inserting and removing the card key from the insertion case is inconvenient for guests. Foreigners who are not accustomed to accommodations in the country may not understand this mechanism and may think that the electrical and electronic devices in the room are broken.

  In addition, the mechanism that uses a card key or the like for unlocking the door of the living room easily leads to a problem that the card key is left in the insertion case when leaving the room and the door cannot be opened. Such an occurrence of an event is not preferable for a guest, nor is it preferable for an accommodation facility that must deal with it.

  In such a situation, in various facilities such as accommodation facilities, offices, and public facilities, it is required to automatically detect entry and exit of a person into and from a living room. In this situation, several techniques have been proposed (for example, see Patent Documents 1, 2, and 3).

JP-A-2002-373388 JP 2011-138645 A JP 2015-122217 A

  Patent Document 1 discloses that a human body detection device 11 or 12 separates and identifies an imaging range of an imaging camera 100 into a plurality of regions, and detects a movement of a monitored person in each region, and a detection region determination unit. A determination processing unit that issues a notification of an abnormality when detecting that the monitored person is in a predetermined state in a predetermined area based on the detection result regarding the movement of the monitored person in 200; A communication processing unit 400 for performing communication with the center device 20 that sets a predetermined state detected by the unit 300 as a parameter P1 (or P2) optimized for each monitored person, and communicates via the network NT. A human body detection device including a parameter storage unit 410 that stores a parameter P1 (or P2) transmitted by the center device 200 via the processing unit 400 is disclosed.

  Patent Literature 1 detects a human body by detecting a motion of the human body. Therefore, when the human body is not moving, it is detected that the human body does not exist. In a toilet or the like, if the operation of the user is stopped, this is the same as turning off the lighting.

  With such a technology for detecting a human body based on the movement of the human body, for example, even if the operation of a guest entering a room of an accommodation facility can be detected and the entrance can be detected, the guest stops operating. If you do, you may misunderstand that you have left the room. In this case, the lighting equipment, the air conditioner, the television, the network equipment, etc. are stopped even though there are guests in the living room, which is extremely inconvenient. In addition, there is also a problem that the movement of the human body outside the detection range of the sensor for detecting the movement of the human body cannot detect entry into the room or detect exit from the room. Particularly, in a facility such as an accommodation facility, there is a problem that the state of entry through the door cannot be detected because the shape of the entrance part from the door and the shape of the living room are different and separated.

  In Patent Literature 2, when the leaving-bed sensor 4b detects leaving the patient, the first lighting device 2b and the second lighting device 3 specified by the lighting device identification information associated with the leaving sensor 4b are turned on. Thereafter, when the exit of the patient is detected, the first lighting device 2b and the second lighting device 3 are turned off. At this time, the lighting device identification information of the first lighting device 2b is stored. When the entrance of the patient is detected, the first lighting device 2b and the second lighting device 3 specified by the stored lighting device identification information are turned on. With this, when the patient leaves the room after leaving the bed, the lighting is turned off and the position illuminating the path is stored, so when the patient returns to the room, the feet near the patient's bed and the feet near the entrance and exit are separated. An illumination system to be illuminated is disclosed.

  Patent Literature 2 detects an occupancy or exit from a bed using a bed exit sensor based on the weight of the patient in the bed. Therefore, it is difficult to apply to various facilities such as accommodation facilities and general facilities. Beds are provided in the accommodation rooms, but guests do not always take the alternative action of sleeping or not. For this reason, there is a problem that it is not possible to detect entry and exit with only a bed leaving sensor, and there is a problem that the technology of Patent Document 2 cannot be applied to automatic detection of entry and exit in a room in a facility.

  Patent Document 3 discloses that the entry / exit detection switch 1 includes two types of human body detection sensors 20a and 30a that output two different types of human body detection signal waveforms arranged in series near the entrance of a room along the entrance / exit direction. An entry / exit detection unit 60 includes an entry / exit direction determination unit 60 that detects a difference between signal waveforms of different types of human body detection signals sequentially detected by the two types of human body detection sensors 20a and 30a and determines an entry / exit direction of a human body. Disclose a switch.

  Patent Literature 3 detects whether or not the user has entered the room based on a change in the waveform in the direction of entering and leaving the room. However, the entrance of an accommodation facility or the like is a narrow space connected to a room, the range of movement of a person in the direction of entry and the direction of exit is narrow, and a waveform often cannot be distinguished between entry and exit. Even if there is a difference in waveforms, it is difficult to perform matching for distinguishing between entry and exit, and there is a possibility that the distinction between entry and exit is erroneous.

  In particular, distinguishing entry and exit under very complicated conditions, such as a difference in waveforms, has a problem that can easily cause an error or a mistake.

  Further, in the technique of Patent Document 3, there is a problem that the occupancy state after entering the room cannot be continuously determined, and the activation state of the electric device or the electronic device cannot be maintained. In addition, large and complicated devices or software are required to detect waveforms, such as analysis of waveform differences, and there are also problems such as cost and difficulty in maintaining reliability. Further, an erroneous determination due to the back and forth movement of a person near the door may occur. For example, there is a case where the user moves to the door to leave the room but then stops leaving the room and returns to the main space of the room. In this case, it is determined that the user has left the room and adversely affects the guest who remains in the room.

  As described above, in the related arts disclosed in Patent Literatures 1 to 3, there is a problem that it is not possible to automatically and accurately detect a user entering and leaving a room in a facility such as an accommodation facility. In particular, there has been a problem that detection cannot be performed according to various aspects such as the structure of the living room and the behavior of the user. In addition, there is a problem that the state of entry cannot be maintained after the entry is detected.

  In view of these problems, an object of the present invention is to provide an entry / exit detection device that can automatically and reliably detect entry and exit from a room such as an accommodation facility.

In view of the above problem, an entrance / exit detection device of the present invention is provided in a first region of a ceiling of an entrance portion in a living room, and a first sensor that detects a human body,
A second sensor for detecting a human body, provided in a second area of the ceiling,
A receiving unit that receives a human body detection result from the first sensor and the second sensor;
Based on the reception result of the receiving unit, a determination unit that determines whether to enter the human body or exit the human body,
The first region is on the entrance side at the entrance portion, the second region is on the living room side at the entrance portion,
The judgment unit is
In the case of the first detection order in which the first sensor detects the human body after the second sensor detects the human body, it is determined that the human body is in the room,
In the case of the second detection order in which the first sensor detects the human body after the second sensor detects the human body, it is determined that the human body has left the room,
The detection range of the first sensor and the detection range of the second sensor are separated.

  ADVANTAGE OF THE INVENTION The entrance / exit detection apparatus of this invention can detect the entrance which opens a door of a room, and enters a room, and the constitution which leaves a room more correctly. In addition, when the entry state is maintained, it is possible to prevent erroneous detection that the room has been exited instead of being in the room.

  In addition, since it can be configured using simple and low-cost members, it can be easily installed in each room of the accommodation facility. In addition, since it is easy to spread, it is preferable for an introducer who aims to reduce power consumption and global environmental burden by automatic detection.

  Detecting entry / exit can automatically start and stop electric and electronic devices in the living room, thereby reducing power consumption and global environmental burden. If it is an accommodation facility, the benefit of the guest increases and it is suitable for the guest who has a problem in language and operation. Of course, the load on the accommodation facility can be reduced, which is a favorable result for both parties.

(Embodiment 1)

(Analysis by the inventor)
In a room of an accommodation facility, a device for inserting a card key or the like at the entrance of the room is provided to save power and save energy, and to reduce the time and effort of management of an operator. By inserting a card key that is shared with the room key into the device, the electrical and electronic devices in the room are activated or operable. When entering the room, the guest inserts the card key into the device to enable use of the electric device, and when leaving the room, removes the card key and stops the electric device and the like.

  However, the guest feels very inconvenient by inserting the room key one by one. Alternatively, there is a concern that the user may forget the key inserted into the device when leaving the room. Also, if you have more than one key, you may leave the room with the card key inserted in the device and leave the electrical equipment in your room operating, which is not desirable in terms of energy saving. there were.

  In other words, it was analyzed that the use of a key such as a card key to detect entry / exit by a user's work often failed to achieve the objectives of energy saving and management reduction, and the problem that the user's labor was increased was analyzed. .

  On the other hand, a technology has been proposed in which a motion sensor is installed at the entrance of a living room to detect entry or exit. Alternatively, there has been proposed a technique of detecting opening and closing of a door to detect entry and exit.

  However, the inventor has analyzed that such a conventionally proposed detection technique has the following inadequacy.

  (1) There is a case where the user leaves the room without entering the room immediately after entering the room. In such a case, the electric device or the electronic device is operated even though there is no user in the room. There may be a case of returning immediately after, or a case of once opening the door and approaching the room, and eventually closing the door and not entering the room.

  (2) The user may return to the room immediately after leaving the room and stop leaving the room. There are cases where the door is opened and the user tries to leave the room. In this case, although the user remains in the room, the electric devices in the room are stopped, which is inconvenient.

  (3) When there are a plurality of users, one may stay in the room and the other may leave. Also in this case, it is inconvenient because it is determined that the user has left the room, and the electric devices in the living room are stopped.

  (4) When viewing with a motion sensor or opening / closing of a door, entry and exit are confused and detected, and it is erroneously determined whether or not the person is present in the living room. If you make a mistake, the electrical equipment in your room will be stopped when it is needed, or will be activated when it is not needed.

  (5) Items (1) to (4) are particularly difficult for a user of a language other than the native language where the accommodation facility is located to grasp the situation, causing inconvenience and trouble.

  The inventor has analyzed that the conventional technology and the proposed (or assumed) technology still have such inconvenience and inadequacy in various facilities including accommodation facilities. That is, it was analyzed that it is necessary to distinguish between entering and leaving, and to perform detection corresponding to human behavior that may occur when entering and leaving.

(Overview)
First, an overall outline of the present invention will be described. FIG. 1 is a block diagram of a living room and an entrance / exit detection device according to Embodiment 1 of the present invention. In order to imagine that the entrance / exit detection device 1 is used in the living room 101, the entrance / exit detection device 1 is shown overlapping the living room 101. The actual entry / exit detection device 1 may be installed in the living room 101 or may be installed separately. Alternatively, it may be partially in the living room 101 and the rest may be outside the living room. Further, the living room 101 is provided with electric devices and electronic devices such as a television, an air conditioner, and a lighting device. Of course, there are other devices and devices.

  The living room 101 is a living room provided in various facilities such as an accommodation facility, an office, a factory, a business place, a public facility, and a residence. In the case of an accommodation facility, the living room 101 in FIG. 1 is the living room 101 of the accommodation facility. At this time, the entrance portion 102 is a portion connected from the door to the inside. The structure of the living room 101 in FIG. 1 may be regarded as showing the structure of the living room of the accommodation facility.

  The living room 101 is provided with an entrance portion 102. The user enters or leaves the room 101 from the entrance portion 102. In the living room 101, the entrance 102 also has a ceiling.

  The entry / exit detection device 1 includes a first sensor 2, a second sensor 3, a receiving unit 4, and a determination unit 5.

  The first sensor 2 is provided in the first area 21 of the ceiling of the entrance part 102. It is provided in the first area 21 and detects a human body from the ceiling in the vertical direction. Of course, a human body may be provided not in the ceiling but in the first area 21 of the wall, and the human body may be detected in the lateral direction from the wall.

  The second sensor 3 is provided in the second area 31 of the ceiling of the entrance part 102. It is provided in the second area 31 and detects a human body from the ceiling in the vertical direction. Of course, it may be provided not in the ceiling but in the second area 31 of the wall, and the human body may be detected from the wall in the lateral direction.

  Here, the first region 21 is on the entrance side of the entrance portion 102, and the second region 31 is on the living room 101 side of the entrance portion 102. At this time, the detection range of the second sensor 2 and the detection range of the second sensor 3 are separated. That is, the first sensor 2 detects a human body at the entrance side without overlapping with the second sensor 3. The second sensor 3 detects a human body in the living room without overlapping with the first sensor 2. Detection is performed in separate and independent detection ranges. As a result, the first sensor 2 and the second sensor 3 do not perform detection in the overlapping range.

  The first sensor 2 and the second sensor transmit (output) a detection result to the receiving unit 4. Only the detected result may be transmitted, or the signal may be transmitted constantly, and the signal to be transmitted may include the presence or absence of the detection. As a result, the receiving unit 4 receives the human body detection results from the first sensor 2 and the second sensor 3. The first sensor 2 and the second sensor 3 and the receiving unit 4 may be electrically or electronically connected wirelessly or wiredly so that an electric signal can be transmitted and received.

  The determining unit 5 distinguishes between entering a human body or leaving a human body based on the reception result of the receiving unit 4.

The determination unit 5
In the case of the first detection order in which the human body is detected by the second sensor 3 after the human body is detected by the first sensor 2, it is determined that the human body is in the room,
In the case of the second detection order in which the first sensor 2 detects the human body after the second sensor 3 detects the human body, it is determined that the human body has left the room.

  That is, according to the detection order of the first sensor 2 and the second sensor 3, it is possible to distinguish and determine whether the human body has entered the room 101 or has exited the room 101. At this time, since the first sensor 2 and the second sensor 3 are separately detected and separated into the entrance side and the living room side, when entering the room, the human body moves from the entrance side to the living room side and exits. In this case, the movement of the human body from the room to the entrance can be detected in the first detection order or the second detection order.

  In the first detection order, the human body enters the room 101 from the outside, and it can be determined that the person enters the room. On the other hand, in the case of the second detection order, the human body goes out of the living room 101 to the outside, and it can be determined that the user has left the room. As described above, the entry / exit detection device 1 of the first embodiment can detect whether a human body is an entry or an exit.

  By being able to be detected separately, the automatic control level of the electric and electronic devices in the living room 101 is improved, and energy saving, convenience for the user, and ease of management for the manager are improved.

(Details and variations of each element)
Next, details and variations of each element will be described.

(First sensor, second sensor)
FIG. 2 is a schematic diagram illustrating detection of a human body by the first sensor and the second sensor according to Embodiment 1 of the present invention. The first sensor 2 is provided in a first area 21, and the second sensor 3 is provided in a second area 31. Here, each of the first sensor 2 and the second sensor 3 may be provided on the ceiling of the entrance portion 102. By being provided on the ceiling, the human body 200 below the ceiling can be detected. This is because the detection from above can reliably detect the human body 200 moving at the entrance.

  In this case, as shown in FIG. 2, each of the first sensor 2 and the second sensor 3 may have an irradiation sensor and irradiate from the ceiling for detection. From above, the first sensor 2 and the second sensor 3 illuminate the human body 200 moving below. The irradiation ensures the detection of the human body 200.

  The irradiation range of the first sensor 2 and the irradiation range of the second sensor 3 are separated as shown in FIG. By being separated, the first sensor 2 detects the human body 200 without overlapping with the second sensor 3, and the second sensor 3 detects the human body 200 without overlapping with the first sensor 2.

  For example, the irradiation range of the first sensor 2 and the second sensor 3 may be separated by the separation member 22 of FIG. As shown on the right side of FIG. 2, when the first detection order is the order of the first sensor 2 and the second sensor 3, the human body 200 moves from the entrance to the room in the entry direction. Conversely, in the case of the second detection order, which is the order of the second sensor 3 and the first sensor 2, the movement of the human body 200 in the exit direction in which the human body exits from the living room via the entrance.

  Based on the first detection order and the second detection order by the first sensor 2 and the second sensor 3, the determination unit 5 determines whether the human body 200 enters or leaves. By being able to distinguish between entering and leaving the room, it is possible to execute control by entering the human body 200 into the living room and control by leaving the room. Furthermore, as will be described later, the presence or absence of the human body 200 can be accurately determined, which also enables appropriate control of electric and electronic devices provided in the living room 101 (energy saving, management, user convenience). Can be realized.

(Judgment of occupancy)
FIG. 3 is a block diagram of the entry / exit detection device according to Embodiment 1 of the present invention. Like FIG. 1, it is shown in a state where the relationship with the living room 101 is clarified. The entry / exit detection device 1 in FIG. 3 further includes an occupancy determination unit 6.

  The occupancy determination unit 6 receives the determination result of the determination unit 5 and determines the occupancy state or the absence state of the human body 200. The determining unit 5 outputs the determination result to the occupancy determining unit 6. Here, when the determination unit 5 determines entry as a determination result, the occupancy determination unit 6 determines the occupancy state for a predetermined time after the determination. In other words, when the determination unit 5 outputs the determination result of entering the room to the occupancy determination unit 6, the occupancy determination unit 6 determines that the room is present. Further, the determination of the occupancy state is maintained for a predetermined time from the time of the determination.

  As described above, the first sensor 2 and the second sensor 3 can accurately determine whether the user is entering or leaving the room. Therefore, the occupancy determination unit 6 can determine the occupancy status.

  If it can be determined that the user is in the room, the operation can be linked to an operation such as activating an electric device or an electronic device provided in the room 101. In addition, since the determination of the occupancy state can be maintained for a predetermined time after the entry determination, even when the human body 200 leaves the room immediately after entering the room, it is possible to prevent the electric device or the electronic device from suddenly stopping (as described later). Then, when it is determined that the state is absent by the exit determination, a process of stopping the electric device or the electronic device in the living room 101 is performed. The user may be surprised or inconvenienced. Such inconvenience can be prevented by maintaining the determination of the occupancy state for a predetermined time).

  The determination unit 5 also outputs the determination result of the exit to the occupancy determination unit 6. Upon receipt of the determination result of the exit, the occupancy determination unit 6 determines the absence status after a lapse of a predetermined time from the determination. That is, when a predetermined time has passed after receiving the room exit determination result, the absence state is determined.

  By not immediately determining the absence state at the time of the exit determination, inconvenience due to the processing based on the determination of the absence state can be prevented. As described above, when it is determined that the user is in the absence state, a process of stopping the electric and electronic devices in the living room 101 is performed. For example, the lighting device and the television provided in the living room 101 are turned off, and the air conditioners are stopped. This is to save energy and ensure management. In addition, the automatic stop also leads to convenience for the user.

  However, it may be inconvenient for the user that the electric device or the electronic device is immediately stopped at the moment when the exit determination is made. For example, if the lighting device is turned off at the moment of leaving the room, an unfamiliar user may be worried that something has gone wrong or an accident. This is especially true for foreign users. In addition, there is a user who has left the room but again checks whether there is any forgotten thing inside the living room 101 with the door open. Also in this case, it is inconvenient that the electric device or the electronic device stops immediately after the exit determination.

  In consideration of such points, the occupancy determination unit 6 determines the absence status after a predetermined time has elapsed after the exit determination. By doing so, the above-described problem immediately after leaving the room can be prevented.

  As described above, the occupancy determination unit 6 can determine the occupancy status and the absence status of the human body 100 in the living room 101. As will be described later, when it can be determined that the occupied state is the occupied state, the electric devices and electronic devices provided in the living room 101 can be automatically activated. Further, when it can be determined that the state is absent, the electric devices and electronic devices provided in the living room 101 can be automatically stopped. By being able to be in the stop state, energy saving and easiness of management can be improved.

(Improvement of occupancy judgment)
FIG. 4 is a block diagram of the entry / exit detection device according to Embodiment 1 of the present invention. FIG. 4 is shown in the same manner as FIG. 1 and FIG. The entrance / exit detection device 1 of FIG. 4 further includes an occupancy detection sensor 7.

  The occupancy detection sensor 7 is provided in the living room 101. The occupancy detection sensor 7 detects that the human body 200 is present in the living room 101. For example, the occupancy detection sensor 7 has an irradiation sensor provided in the living room 101 and irradiates the inside of the living room 101 to detect the human body 200. When detecting the human body 200 in the irradiation range, it is detected that the human body is in the room. The occupancy detection sensor 7 outputs a detection result to the occupancy determination unit 6.

  When the occupancy detection sensor 7 detects the occupancy of the human body 200, the occupancy determination unit 6 determines that the occupant is in the occupancy state (holds the determination). That is, the occupancy determination unit 6 determines the occupancy status by the entry determination. Further, when the human body 200 is occupied by the occupancy detection sensor 7, the determination of the occupancy state is held. As a result, if the human body 200 is in the living room 101 after entering the room, the activation state of the electric appliance or the like can be maintained while the occupancy state is being determined.

  In addition, when a plurality of users use the room 101, the remaining users may remain in the room 101 even if one person leaves the room. At this time, the determination unit 5 determines that the person has left the room. If the occupancy determination unit 6 is based solely on the exit determination, it determines the absence state. In this case, even when the remaining users remain in the room 101, there is a problem that the electric devices and the like in the room 101 are stopped.

  On the other hand, the occupancy detection sensor 7 provided in the living room 101 can detect the remaining user. Based on the detection result, the occupancy determination unit 6 can maintain the determination that the human body 200 is in the occupancy state, and can maintain the operation state of the electric device or the like. As a result, even if there is a user who has left the room, it is possible to respond to the fact that another user remains.

  As described above, the occupancy detection sensor 7 can detect the human body 200 by irradiating a wide area of the living room 101 or the like. Therefore, it can be detected with high accuracy that the user is inside the living room 101. For example, the occupancy detection sensor 7 includes an irradiation sensor having a wide irradiation range and is installed on a ceiling. As a result, the human body 200 can be detected in a wide range of the living room 101. Alternatively, an irradiation sensor having a wide directivity on a horizontal plane may be installed on a wall to reliably detect the human body 200 on the horizontal plane.

  Further, the detection range of the occupancy detection sensor 7, the detection range of the first sensor 2, and the detection range of the second sensor 3 are separated from each other. In the case of an irradiation sensor, the irradiation range of the occupancy detection sensor, the irradiation range of the first sensor 2, and the irradiation range of the second sensor 3 are separated. This is because the separated state prevents entry, exit, and occupancy detection by mistake.

  As described above, the first sensor 2 and the second sensor 3 are separated from each other, and it is possible to detect the human body 200 by distinguishing between entering and leaving the room. Further, since the detection range of the occupancy detection sensor 7 is separated from the detection ranges of the first sensor 2 and the second sensor 3, there is no problem that adversely affects the determination of entering / leaving.

  As described above, it is possible to determine the occupied state or the absent state based on the occupancy detection result in the living room 101 as well as the occupancy state or the absent state due to the entry / exit. As a result, it is possible to accurately determine the occupied state and the absent state even when entry and exit are performed immediately after being switched, or when there are a plurality of users.

(Operation detection)
FIG. 5 is a block diagram of the entry / exit detection device according to Embodiment 1 of the present invention. The entry / exit detection device 1 of FIG. 5 further includes an operation detection unit 8. The operation detection unit 8 detects operation detection of operation of at least one of an electric device and an electronic device provided in the living room 101. For example, the operation detection unit 8 performs various operations that the user may operate in the living room 101, such as a change in the channel of the television, a change in the set temperature of the air conditioner, or a switch on the lighting device. Is detected as operation detection.

  The operation detection unit 8 outputs the detected operation detection to the occupancy determination unit 6. When the operation detection unit 8 detects the operation detection, the occupancy determination unit 6 determines that the human body 200 is present in the living room 101. This is because the operation of the electric device or the electronic device indicates that the user is in the room.

  If the occupancy determination unit 6 determines that the occupancy is in the occupancy state or holds the occupancy state, the electric devices and the electronic devices can maintain the operation state. As described above, it is possible to determine that the human body 200 is in the room from a wider detection content. As a result, it is possible to improve the accuracy of determining the occupied state and the absent state. In particular, the judgment is based on the actual use of the living room 101 by the actual user, and is suitable for use in a real situation.

(Leave and stay)
The determination unit 5 determines entry and exit based on the detection results of the first sensor 2 and the second sensor 3. At this time, in the case of the second detection order in which the human body 200 is detected by the second sensor 3 and then the human body 200 is detected by the first sensor 2, the determination unit 5 determines that the human body 200 has left the room.

  The occupancy determination unit 6 receiving the result of the exit from the determination unit 5 determines that the state is absent after a predetermined time has elapsed. However, as described above, in at least one of the case where the occupancy detection sensor 7 detects the occupancy of the human body 200 and the case where the operation detection unit 8 detects the operation detection, the occupancy determination unit 6 sets The judgment of the room state is maintained.

  In such a case, there are a plurality of users or a situation where the users return immediately after leaving the room. In such a situation, it is preferable to maintain the determination as the occupancy state.

  As described above, by judging the occupied state and the absent state together with the detection results of the occupancy sensor 7 and the operation detection unit 8, it is possible to make a more realistic determination.

  The entry / exit detection device 1 of the first embodiment can determine the occupied state and the absent state based on the entry / exit determination by the first sensor 2 and the second sensor 3. In addition, it is possible to determine the occupied state and the absent state by using the entry or exit as a time starting point. As a result, it is possible to automatically start and stop the electric and electronic devices in the living room 101 at the optimal timing.

  In addition, the occupancy detection sensor 7 and the operation detection unit 8 can determine the occupancy status or the absence status in accordance with the realistic behavior of the user. The ability to make highly accurate judgments that correspond to realistic actions enables automatic starting, automatic stopping, and maintaining the starting state of electrical and electronic devices.

  (Embodiment 2)

  Next, a second embodiment will be described. In the second embodiment, control in living room 101 based on the determination of the occupied state and the absence state will be described. FIG. 6 is a block diagram of an entry / exit detection device according to Embodiment 2 of the present invention.

  When the occupancy determination unit 6 determines that the occupancy is in the occupancy state, the occupancy determination unit 6 activates the electric and electronic devices provided in the living room 101. For example, the lighting device is turned on. Alternatively, start the television. Alternatively, the air conditioner is operated. When the occupancy determination unit 6 determines that the user is in the occupancy state, it is automatically activated, so that the user can use these electric and electronic devices at the same time as entering the room, which is very convenient. It is.

  Unlike the prior art, there is no need to insert a card key or the like into the device, which is preferable in terms of reducing the effort and understanding. In addition, since there is no need to insert or remove a card key or the like, problems such as leaving the room with the key forgotten are less likely to occur. In addition, even for foreigners whose language is difficult to understand, it is very convenient to start up electrical equipment at the same time as entering the room.

  In addition, after being activated by entering the room, the functions such as the occupancy detection sensor 7 and the operation detection unit 8 maintain the occupancy determination. Due to this holding, the activated electric device or electronic device does not stop except for the operation of the user. Also in this respect, it does not cause inconvenience to the user.

  In addition, when it is determined that the room is absent, the occupancy determining unit 6 stops the electric device or the electronic device. For example, the lighting device is turned off. Stop the air conditioner. The occupancy determination unit 6 turns off the television. Alternatively, disconnection of a network device may be performed.

  As described above, by the automatic stop by the occupancy determination unit 6, the electric device and the electronic device are stopped without the user performing the operation such as the stop. As a result, energy saving can be achieved without requiring the user. In addition, energy saving can be realized without the labor of the administrator. In terms of cost and environment, there are benefits for both users and administrators.

  At this time, the absence state is determined after a lapse of a predetermined time from the room exit determination, so that the electric devices and the like are stopped a little after the user leaves the room. By not being stopped immediately, the user can be prevented from being surprised or troubled. In particular, foreigners with different languages do not have any concerns about breakdowns. In addition, even if the user wants to confirm a lost item in the room immediately after leaving the room, the user does not stop immediately, which is convenient for the user.

  In addition, even when the exit is determined, as described in the first embodiment, if the user is in the room by the in-room detection sensor 7 and the operation detection unit 8, the human body 200 is in the in-room state. A decision is made. At this point, if the user is actually present, the activation state of the electric device or the like is maintained. As a result, there is no inconvenience for the user.

  Of course, as described above, in the case where it is determined that the state is absent in consideration of the above, the electric device and the like are stopped. The user can save energy without extra work.

  As shown in FIG. 6, the electrical devices and electronic devices provided in the living room 101 are at least one of a lighting device, a lighting device, an air conditioner, a video device (such as a television or a video), and a network device. Of course, these are examples, and other devices and devices may be used.

  The electric and electronic devices provided in the living room 101 are automatically started in the occupied state and automatically stopped in the absent state, so that they are suitable for energy saving and environmental consideration, and can reduce the labor of the user and the administrator.

(Control via control unit)
As described above, the occupancy determination unit 6 processes the automatic start and automatic stop of the electric and electronic devices. Alternatively, as shown in FIG. 6, the entry / exit detection device 1 further includes a control unit 9, and in response to the determination result of the occupancy determination unit 6, the control unit 9 controls automatic start and automatic stop. It may be.

  The control unit 9 controls the automatic start and the automatic stop of the electric device or the electronic device, so that fine control or intensive control can be performed. In addition, since the control unit 9 is formed integrally with the electric device or the electronic device, control can be performed in response to replacement of the electric device or the electronic device. Alternatively, control accuracy can be improved.

  As described above, the control of the automatic start and the automatic stop by the control unit 9 may be performed.

(Stop procedure in absence state)
In the absent state, the occupancy determination unit 6 or the control unit 9 automatically stops electric and electronic devices provided in the living room 101. At this time, it is also preferable that the occupancy determining unit 6 or the control unit 9 controls the automatic stop in the order of the reduction of the illuminance of the lighting device, the stop of the video device, the stop of the air conditioner, and the stop of the lighting device.

  By performing the stop control in this order, when the user leaves the room, the control is gentle to the user. At the time of leaving the room, it is possible to feel that the illuminance of the lighting device is reduced and the automatic stop is started. In addition, since the light does not turn off immediately, there is no inconvenience in checking forgotten items when leaving the room. Further, since the video device disappears and the air conditioner subsequently disappears, it is possible to prevent the air conditioner from operating and feeling hot or cold when the user leaves the room.

  In particular, in leaving the room, after passing through the first sensor 2 and the second sensor 3, it may take time until the room actually leaves. In this case, it is possible to use necessary electric devices and the like in the work and time required when leaving the room. Therefore, inconvenience when the user leaves the room can be prevented, and both energy saving and convenience can be achieved.

  Thus, it is preferable that the order of the automatic stop is appropriately controlled.

  As described above, the entry / exit detection device 1 according to the second embodiment can automatically start and stop electric devices and electronic devices in the living room 101 in accordance with the occupied state and the absent state. As a result, energy saving and convenience for the user or administrator can be improved. Of course, effects such as cost reduction also occur.

  The entry / exit detection devices described in the first and second embodiments are examples for explaining the purpose of the present invention, and include modifications and alterations without departing from the spirit of the present invention.
