Description

TECHNICAL FIELD The present invention relates to a room entry/exit detection device capable of reliably detecting a room entry state and a room exit state with a simple configuration.

2. Description of the Related Art In recent years, in many lodging facilities such as hotels, internal electric devices and electronic devices are operated according to the stay of guests. This is to realize a reduction in electricity charges and a reduction in global environmental load by keeping unnecessary electrical equipment and electronic devices in a stopped state or in a standby state when no guests are present.

Similarly, when a guest enters the room, it is also preferable to start up the necessary electrical and electronic devices without bothering the guest. This is because the level of service to guests can be improved. In addition, there are many foreign guests staying at lodging facilities, and it is sometimes difficult for them to immediately understand how to operate the electrical and electronic devices installed in the rooms. Also in this case, it is convenient for the guest that these are automatically activated when entering the room.

For the same reason, it is preferable that electrical and electronic devices such as lighting fixtures, air conditioners and televisions are deactivated when the guest leaves the room. This is because, as described above, a reduction in electricity charges and a reduction in the load on the global environment can be realized. Guests are often in a hurry when leaving their rooms. This is because he is preoccupied with things like going out for errands. Also, unlike in one's own home, people are less conscious of turning off electric devices and electronic devices. This is especially true for foreign guests who have difficulty understanding the language of operating electrical and electronic devices.

From this point of view, it is also preferable that the electrical equipment and electronic devices automatically stop when the guest leaves the room.

Starting electrical and electronic devices when a guest enters the room and shutting them down when the guest leaves the room is costly, the global environment, the benefit of the guest, and the performance of the accommodation facility. It is suitable in various aspects such as convenience. In particular, it is preferable to automatically start up when entering the room and stop when leaving the room.

At present, for example, by inserting a card key or the like used to enter a room into an insertion case near the entrance, it is determined whether a guest enters the room. Based on this room entry determination, electrical equipment 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 assumed that the guest has left the room, and the electrical equipment and electronic devices are stopped. In this manner, entry and exit of the room are electronically grasped according to the actions of the guest, and the electrical equipment and electronic devices are automatically started and stopped.

However, it is inconvenient for guests to insert and remove the card key from the insertion case. Foreigners who are unfamiliar with accommodation facilities in the country may not understand this mechanism and may think that the electrical and electronic equipment in the room is broken.

In addition, due to the mechanism of using a card key to unlock the door of the room, it is easy to cause problems such as leaving the card key in the insertion case when leaving the room, making it impossible to open the door. Occurrence of such an event is not desirable for the guests, and it is also undesirable for the accommodation facilities that have to deal with it.

Under these circumstances, there is a demand for automatic detection of the entry and exit of people from rooms in various facilities such as lodging facilities, offices, and public facilities. In this situation, several techniques have been proposed (see Patent Documents 1, 2, and 3, for example).

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

Japanese Patent Laid-Open No. 2002-200000 describes a detection area determination unit 200 that separates and identifies an imaging range of an imaging camera 100 into a plurality of areas and detects the movement of a monitored person in each area, and this detection area determination unit. Determination processing unit 300 for issuing a notification of abnormality when it is detected 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 communicating with the center device 20, which sets a predetermined state detected by the unit 300 as an optimized parameter P1 (or P2) for each monitored person, and a communication processing unit 400 for communicating with the network NT. A human body detecting device comprising a parameter storage section 410 that stores the parameter P1 (or P2) sent by the center device 200 via the processing section 400 is disclosed.

Patent Document 1 detects the human body by detecting the movement of the human body. Therefore, when the human body is not moving, it is detected that the human body does not exist. It is the same as turning off the lights in a toilet or the like if the user does not move.

With such a technology that detects the human body based on the movement of the human body, for example, even if it is possible to detect the entry of a guest entering a room of an accommodation facility, the guest stops moving. If you do, you may mistakenly think that you have left the room. In this case, even though there are guests in the room, the lighting equipment, air conditioning equipment, television, network equipment, etc. will stop, which is extremely inconvenient. In addition, there is also the problem that the movement of the human body outside the detection range of the sensor that detects the movement of the human body cannot be detected as entering the room or being unable to be detected as leaving the room. In particular, in facilities such as lodging facilities, the shape of the entrance from the door and the living room are different, so there is also the problem that it is not possible to detect the state of entering the room through the door.

According to Patent Document 2, when the bed-leaving sensor 4b detects that the patient is leaving the bed, the first lighting device 2b and the second lighting device 3 specified by the lighting device identification information associated with the bed-leaving sensor 4b are turned on. After that, 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. Then, when it is detected that the patient has entered the room, the first lighting device 2b and the second lighting device 3 specified by the stored lighting device identification information are turned on. As a result, when the patient leaves the room after leaving the room, the lights are turned off and the position of lighting the path is memorized. An illuminated lighting system is disclosed.

Patent Document 2 uses a sensor for getting out of bed based on the patient's weight on the bed to detect the presence or absence of the patient. For this reason, it is difficult to apply in various facilities such as lodging facilities and general facilities. Rooms in lodging facilities are equipped with beds, but it is not always the case that guests are either sleeping on the bed or not. For this reason, there is a problem that it is not possible to detect entry and exit of a room only with a bed sensor, and the technology of Patent Document 2 cannot be applied to automatic detection of entry and exit in a room of a facility.

According to Patent Document 3, the entry/exit detection switch 1 has two types of human body detection sensors 20a and 30a that output two different types of signal waveforms of human body detection signals, arranged in series near the doorway of a room along the room entry/exit direction. A room entrance/exit direction determination unit 60 for determining the entrance/exit direction of a human body by detecting a difference in signal waveforms of different types of human body detection signals sequentially detected by the two types of human body detection sensors 20a and 30a. Disclose the switch.

In Patent Document 3, it is detected whether the user is entering or leaving the room from the change in the waveform in the direction of entering or leaving the room. However, the entrances and exits of lodging facilities and the like are narrow spaces that lead to rooms, and the movement range of people in the direction of entering and exiting the room is narrow, and the waveform often becomes such that entry and exit cannot be distinguished. Even if there is a difference in the waveforms, matching for distinguishing between entering and leaving the room becomes difficult, and there is a possibility that entering and leaving the room may be erroneously distinguished.

In particular, distinguishing between entering and exiting a room based on very complicated conditions such as differences in waveforms tends to cause errors and misjudgments.

In addition, the technique of Patent Document 3 also has the problem that it is not possible to continuously determine whether a person is in a room after entering the room, and it is not possible to maintain the start-up state of electrical equipment and electronic devices. In addition, waveform detection requires a large-scale and complicated device or software for analysis of waveform differences, and there are problems such as cost and difficulty in maintaining reliability. In addition, an erroneous judgment may occur due to back and forth movements of a person near the door. For example, the user moved to the door to leave the room, but then stopped leaving the room and returned to the main space of the living room. In this case, it is determined that the guest has left the room, and the guest staying in the room is adversely affected.

As described above, the conventional technologies disclosed in Patent Literatures 1 to 3 have the problem of being unable to automatically and accurately detect the entry and exit of users in rooms of facilities such as lodging facilities. In particular, there is 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 also a problem that the state of entering the room cannot be maintained after detection of entering the room.

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

In view of the above problems, the room entrance/exit detection device of the present invention includes a first sensor provided in a first area of the ceiling at the entrance of a living room and detecting a human body;
a second sensor provided in a second area of the ceiling at the entrance of the living room and detecting a human body;

In the case of the second detection order in which the human body is detected by the first sensor after the human body is detected by the second sensor, it is determined that the human body has left the room,
the detection range of the occupancy detection sensor, the detection range of the first sensor, and the detection range of the second sensor are separated ,
further comprising a room presence determination unit that determines whether the human body is in the room or not, based on the determination result of the determination unit;
When the determination unit determines that the user is in the room, the presence determination unit determines and maintains the state of being in the room for a predetermined time after the determination,
When the determination unit determines to leave the room, the room presence determination unit determines that the person is absent after a predetermined time has passed since the determination,

further comprising an operation detection unit that detects an operation detection that at least one of the electrical equipment and the electronic device provided in the living room is operated,
The operation detection unit outputs the detected operation detection to the presence determination unit,
Even if the determination unit determines that the human body has left the room, the presence detection unit detects the presence of the human body in the room and/or the operation detection unit detects the presence of the human body. retains the occupancy judgment,
If the occupancy determining unit determines that the user is in the room, the occupancy determining unit activates the electrical equipment and electronic devices provided in the occupant room,
If the room presence determination unit determines that the user is absent, the electric device and the electronic device are stopped,
Electrical and electronic equipment includes lighting equipment, air conditioning equipment, and video equipment,
When determining that the user is absent, the room occupancy determination unit performs control in the order of reducing the illuminance of the lighting equipment, stopping the video device, stopping the air conditioning equipment, and stopping the lighting equipment .

The room entrance/exit detector of the present invention can more accurately detect entering a room by opening the door of the living room and leaving the room. Also, when the state of entering the room is maintained, it is possible to prevent erroneous detection that the user has left the room instead of being in the room.

Moreover, since it can be configured using simple and low-cost members, it can be easily installed in each room of an accommodation facility. Moreover, since it is easy to spread, automatic detection is preferable for those who aim to reduce power consumption and global environmental load.

By detecting the entry and exit of the room, it is possible to automatically start and stop the electrical equipment and electronic devices in the living room, so it is possible to reduce power consumption and global environmental load. If it is a lodging facility, it will be more convenient for the lodger, and it is also suitable for the lodger who has problems with language and operation. Of course, the burden on the accommodation facility side can also be reduced, which is a favorable result for both parties.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)

(Analysis by inventor)
A room in an accommodation facility is equipped with a device for inserting a card key or the like at the entrance of the room in order to save power or save energy or to reduce the management effort of the operator. By inserting the card key, which is shared with the room key, into the device, the electrical and electronic devices in the room can be activated or operable. When entering the room, the guest inserts the card key into the device to enable the use of electrical equipment, and when leaving the room, the guest removes the card key to stop the electrical equipment.

However, it is very inconvenient for guests to insert the room key one by one. Alternatively, there is a concern that the user may forget the key while it is still inserted in the device when leaving the room. Also, if you have more than one key, you may leave the room with the card key inserted into the device, leaving the electrical equipment in the room running, which is not desirable from an energy-saving point of view. there were.

In other words, we analyzed that using a key such as a card key to detect entry and exit by user's work often fails to achieve the goals of energy saving and management reduction, and has the problem of increasing the trouble of the user. .

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

However, the inventors have analyzed that such conventionally proposed detection techniques have the following inadequacies.

(1) A user may leave the room without entering the room immediately after entering the room. In such a case, the electrical equipment and electronic devices are in operation even though there is no user in the room. There may be a case where the user returns immediately afterward, or a case where the user does not enter the room after opening the door and closing the door after all.

(2) The user may return to the room immediately after leaving the room and stop leaving the room. Although he tried to leave the room by opening the door, he remembered something to do and closed the door and returned to the room, or returned immediately after leaving the room. In this case, although the user remains in the room, the electrical equipment in the room stops, which is inconvenient.

(3) If there are multiple users, it is possible that one person will stay in the room and the other person will leave. In this case as well, it is determined that the user has left the room, and the electrical equipment in the room is stopped, which is inconvenient.

(4) If a human sensor or door opening/closing is used, entry and exit of a room are detected confusedly, and it is mistaken whether the person is in the room or not. If you make a mistake, the electrical equipment in your room will stop when you need it, or start up when you don't need it.

(5) (1) to (4) are particularly difficult for users of languages other than their mother tongue, where lodging facilities are available, and cause inconvenience and trouble.

The inventors have analyzed that conventional technologies and proposed (or assumed) technologies still have such inconveniences and inadequacies in various facilities including lodging facilities. In other words, we analyzed that it is necessary to distinguish between entry and exit and to detect human behavior that may occur when entering and exiting a room.

(overall overview)
First, an overview 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 room entry/exit detection device 1 is used in a living room 101 , the room entry/exit detection device 1 is shown superimposed on the living room 101 . The actual room entry/exit detector 1 may be installed in the living room 101 or may be installed at a distance. Alternatively, it may be partially in the room 101 and the rest outside the room. In addition, the living room 101 is equipped with electric devices and electronic devices such as a television, an air conditioner, and a lighting device. Of course, there are devices and devices other than these.

The living room 101 is a living room provided in various facilities such as lodging facilities, offices, factories, workplaces, public facilities, and residences. 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 that leads from the door to the inside. The structure of the living room 101 in FIG. 1 can be regarded as showing the structure of a living room in an accommodation facility.

A living room 101 is provided with an entrance portion 102 . A user enters or leaves the living room 101 through this entrance portion 102 . In the living room 101, the entrance part 102 is also provided with a ceiling.

The room entry/exit detector 1 includes a first sensor 2 , a second sensor 3 , a receiver 4 and a determination unit 5 .

A first sensor 2 is provided in a first area 21 of the ceiling of the entrance section 102 . It is provided in the first area 21 and detects a human body vertically from the ceiling. Of course, it may be provided in the first area 21 of the wall instead of the ceiling, and the human body may be detected laterally from the wall.

A second sensor 3 is provided in a second area 31 of the ceiling of the entrance section 102 . It is provided in the second area 31 and detects a human body vertically from the ceiling. Of course, it may be provided in the second region 31 of the wall instead of the ceiling, and the human body may be detected laterally from the wall.

Here, the first region 21 is the entrance side of the entrance portion 102 and the second region 31 is the 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 the human body without overlapping with the second sensor 3 on the entrance side. The second sensor 3 detects the human body without overlapping with the first sensor 2 on the living room side. They are detected 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) detection results to the receiver 4 . Only the detection result may be transmitted, or it may be transmitted all the time and the transmitted signal may include the presence or absence of detection. As a result, the receiving unit 4 receives 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 receiver 4 may be electrically or electronically connected wirelessly or by wire so that they can transmit and receive electrical signals.

Based on the reception result of the receiving unit 4, the determining unit 5 determines whether the human body enters the room or leaves the room.

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

That is, depending on the order of detection by the first sensor 2 and the second sensor 3, whether the human body has entered the living room 101 or left the living room 101 can be discriminated. At this time, the first sensor 2 and the second sensor 3 detect separately, and are divided into the entrance side and the living room side, so that when entering the room, the human body moves from the entrance side to the living room side and leaves the room. In this case, the movement of the human body from the living room side to the entrance side can be detected in the first detection order or the second detection order.

In this first detection order, the human body is entering from the outside of the room 101 and can be determined as entering the room. On the other hand, in the case of the second detection order, the human body is moving out of the room 101, and it can be determined that the user has left the room. In this manner, the room entry/exit detector 1 of Embodiment 1 can detect whether the human body is entering or exiting the room.

By being able to distinguish and detect, the level of automatic control of electrical equipment and electronic devices in the living room 101 is improved, and energy saving, convenience for users, and ease of management by administrators 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 a first sensor and a second sensor according to Embodiment 1 of the present invention. A first sensor 2 is provided in the first area 21 and a second sensor 3 is provided in the 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 from the ceiling can be detected. This is because the detection from above ensures the detection of the human body 200 moving through the entrance.

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

The irradiation ranges of the first sensor 2 and 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 ranges of the first sensor 2 and the second sensor 3 may be separated by the separation member 22 shown in FIG. As shown on the right side of FIG. 2, in the case of the first detection order, which is the order of the first sensor 2 and the second sensor 3, the human body 200 moves in the direction of entering the living room from the entrance. Conversely, in the case of the second detection order, which is the order of the second sensor 3 and the first sensor 2, the human body 200 moves in the direction of leaving the living room through 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 the room. By being able to distinguish between entering and leaving the room, it is possible to control the human body 200 by entering the room or by leaving the room. Furthermore, as will be described later, it is possible to accurately determine whether or not the human body 200 is in the room. can be realized.

(judgment of room presence)
FIG. 3 is a block diagram of the room entry/exit detector according to Embodiment 1 of the present invention. As in FIG. 1, it is shown in such a state that the relationship with the room 101 is clarified. The room entry/exit detection device 1 of FIG.

Based on the determination result of the determination unit 5, the room presence determination unit 6 determines whether the human body 200 is in the room or not. The determination unit 5 outputs the determination result to the presence determination unit 6 . Here, when the determination unit 5 determines that the person has entered the room as a determination result, the room presence determination unit 6 determines that the person is in the room for a predetermined period of time after the determination. In other words, when the determination unit 5 outputs the result of determination that the person is in the room to the room presence determination unit 6, the room presence determination unit 6 determines that the person is in the room. Furthermore, this determination of the state of being in the room is maintained for a predetermined period of time from the time of determination.

In this way, since it is possible to accurately determine whether the person is entering or leaving the room by the first sensor 2 and the second sensor 3, the human body 200 is in the living room 101 when the room is entered. Therefore, the room presence determination unit 6 can determine that the room is in the presence state.

If it can be judged as being in the room, it can lead 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 state of being in the room can be maintained for a predetermined time after the determination of entering the room, even when the human body 200 leaves the room immediately after entering the room, it is possible to prevent sudden stoppage of electrical equipment and electronic devices (as will be described later). When it is determined that the user is absent, the electrical equipment and electronic devices in the living room 101 are stopped. Such inconvenience can be prevented by maintaining the determination of the room presence state for a predetermined period of time).

The determination unit 5 also outputs the determination result of leaving the room to the presence determination unit 6 . Upon receipt of the result of the determination of leaving the room, the occupancy determining unit 6 determines that the user is absent after a predetermined period of time has elapsed from the time of the determination. That is, after a predetermined period of time has elapsed after receiving the room leaving determination result, it is determined that the user is absent.

Inconvenience due to the processing based on the determination of the absence state can be prevented by not immediately determining the absence state when leaving the room. As described above, when it is determined that the user is absent, the electrical equipment and electronic devices in the living room 101 are stopped. For example, the lighting device and the television provided in the living room 101 are turned off, and the air conditioner is stopped. This is for saving energy and ensuring management. In addition, the automatic stop leads to convenience for the user.

However, it may be inconvenient for the user that the electric device or electronic device is immediately stopped at the moment when the room leaving determination is made. For example, if the lighting device is turned off at the moment of leaving the room, the unfamiliar user may become worried that some sort of failure or accident has occurred. If you are a foreign user, it is even more so. There are also users who, after leaving the room, leave the door open and check again whether there is anything left inside the living room 101 . In this case as well, it is inconvenient for the electrical equipment or electronic device to stop immediately after the room exit determination.

In consideration of such points, the room presence determination unit 6 determines the absence state after a predetermined period of time has passed after the room leaving determination. By doing so, it is possible to prevent the above-described problems immediately after leaving the room.

In this way, the room presence determination unit 6 can determine whether the human body 100 is in the room 101 or not. As will be described later, when it can be determined that the user is in the room, the electrical equipment and electronic devices installed in the room 101 can be automatically activated. In addition, when it can be determined that the person is absent, the electrical equipment and electronic devices installed in the living room 101 can be automatically stopped. Being able to stop the operation can improve energy saving and ease of management.

(Improvement of room presence judgment)
FIG. 4 is a block diagram of the room entry/exit detector according to Embodiment 1 of the present invention. FIG. 4 is shown in the same manner as FIGS. 1 and 3. FIG. The room entry/exit detection device 1 of FIG. 4 further includes a room presence detection sensor 7 .

The room detection sensor 7 is provided in the living room 101 . The presence detection sensor 7 detects that the human body 200 exists 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 the human body 200 is detected within the irradiation range, the human body is detected as being in the room. The room presence detection sensor 7 outputs the detection result to the room presence determination unit 6 .

When the presence detection sensor 7 detects that the human body 200 is in the room, the room presence determination unit 6 determines that the human body 200 is in the room (holds the determination). That is, the room presence determination unit 6 determines the room presence state based on the room entry determination. Furthermore, if the human body 200 is found to be in the room by the room presence detection sensor 7, the determination of the room presence state is maintained. As a result, if the human body 200 is in the living room 101 after entering the room, it is possible to maintain the start-up state of the electric appliance or the like while keeping the determination of the state of being in the room.

Moreover, when a plurality of users use the living room 101, the remaining users may remain in the living room 101 even if one person leaves the room. At this time, the determination unit 5 determines that one person has left the room. If the room presence determination unit 6 is based only on this room leaving determination, the absence state is determined. In this case, even if the rest of the users remain in the living room 101, there arises a problem that the electrical equipment in the living room 101 stops.

On the other hand, the presence detection sensor 7 provided in the living room 101 can detect remaining users. Based on this 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 operating state of electrical equipment and the like. As a result, even if there is a user who has left the room, it is possible to deal with the presence of other users.

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

Furthermore, the detection range of the presence 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 the irradiation sensor, the irradiation range of the room presence detection sensor, the irradiation range of the first sensor 2 and the irradiation range of the second sensor 3 are separated from each other. This separation state eliminates erroneous detection of entry, exit, and presence in the room.

In this manner, the first sensor 2 and the second sensor 3 are separated, and the human body 200 can be detected by distinguishing between entering and leaving the room. In addition, since the detection range of the room presence detection sensor 7 is separated from the detection ranges of the first sensor 2 and the second sensor 3, there is no problem of adversely affecting the determination of entering or leaving the room.

In this way, it is possible to determine whether a person is in a room or not, based not only on the determination of whether or not a person is in the room by entering or leaving the room, but also based on the result of detection of the presence in the room 101 . As a result, it is possible to accurately determine whether the user is in the room or not, even when the users enter and leave the room immediately after each other, or when there are a plurality of users.

(operation detection)
FIG. 5 is a block diagram of the room entry/exit detector according to Embodiment 1 of the present invention. The room entry/exit detector 1 of FIG. 5 further includes an operation detector 8 . The operation detection unit 8 detects operation detection that at least one of the electrical equipment and the electronic device provided in the living room 101 is operated. For example, the operation detection unit 8 detects various operations that are considered to be performed by the user in the living room 101, such as changing the TV channel, changing the set temperature of the air conditioner, turning on the switch of the lighting device, and the like. is detected as operation detection.

The operation detection unit 8 outputs the detected operation detection to the room presence determination unit 6 . When the operation detection unit 8 detects the operation detection, the presence determination unit 6 determines that the human body 200 is present in the living room 101 . This is because the fact that an electrical device or electronic device is being operated indicates that the user is in the room.

If the room presence determination unit 6 determines that the user is in the room presence state, or if the presence state is maintained, the electrical equipment, the electronic device, and the like can maintain the operating state. In this way, it becomes possible to determine that the human body 200 is in the room based on a wider range of detection contents. As a result, it is possible to improve the accuracy of determining whether a person is in the room or not. In particular, the decision is based on the actual use of the living room 101 by the actual user, and is suitable for use in an actual situation.

(exit and stay)
Based on the detection results of the first sensor 2 and the second sensor 3, the determination unit 5 determines whether to enter or leave the room. At this time, in the case of the second detection order in which the second sensor 3 detects the human body 200 and then the first sensor 2 detects the human body 200, the determination unit 5 determines that the human body 200 has left the room.

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

In such a case, it indicates a situation where there are multiple users or a user returns immediately after leaving the room. In such a situation, it is preferable to maintain the judgment as being in the room.

In this way, by judging whether the person is in the room or not, in combination with the detection results of the room presence sensor 7 and the operation detection unit 8, it is possible to make a decision that corresponds to reality.

The room entrance/exit detector 1 of Embodiment 1 can determine whether a person is in a room or not, based on the determination of room entry and room exit by the first sensor 2 and the second sensor 3 . In addition, it is possible to determine whether a person is in a room or not, using the entry or exit of a room as a temporal starting point. As a result, automatic start-up and automatic stop of the electrical equipment and electronic devices in the living room 101 can be performed at optimum timing.

In addition, the room presence detection sensor 7 and the operation detection unit 8 can determine whether the user is in the room or not, according to the user's realistic behavior. By being able to make highly accurate judgments that correspond to realistic actions, it is possible to accurately perform automatic startup, automatic shutdown, and maintenance of the startup state of electrical and electronic devices.

(Embodiment 2)

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

When determining that the person is in the room, the presence-in-room determination unit 6 activates the electrical equipment and the electronic device provided in the room 101 . For example, a lighting device is turned on. Or turn on your TV. Alternatively, the air conditioner is operated. When the occupancy determining unit 6 determines that the user is in the room, it is automatically activated so that the user can use these electric devices and electronic devices at the same time as entering the room, which is very convenient. is.

Unlike the prior art, there is no need to insert a card key or the like into the device, and it is preferable in terms of reducing labor and understanding. In addition, since there is no need to insert or take out a card key or the like, problems such as leaving the room while forgetting the key are less likely to occur. In addition, even for foreigners who do not understand the language, it is very convenient to start up electrical equipment at the same time as they enter the room.

Further, after entering the room and being activated, the function of the room presence detection sensor 7, the operation detection unit 8, and the like maintains the determination of the room presence state. Due to this holding, the activated electric device or electronic device will not be stopped except by the user's operation. In this respect as well, the user is not inconvenienced.

In addition, when the room presence determination unit 6 determines that the user is absent, the electric device and the electronic device are stopped. For example, turn off the lighting device. Stop the air conditioner. The occupancy determination unit 6 performs such as turning off the television. Alternatively, network devices may be disconnected.

In this manner, the automatic shutdown by the presence-in-room determining unit 6 stops the electrical equipment and electronic devices without the user having to perform work such as shutdown himself. As a result, energy saving can be achieved without requiring the user's trouble. In addition, it is possible to save energy by omitting the trouble of the administrator. There are advantages for both users and administrators in terms of cost and environment.

At this time, since it is determined that the user is absent after a predetermined time has passed since the determination of leaving the room, the electrical equipment and the like are stopped after a short period of time after the user has left the room. By not stopping immediately, it is possible to prevent the user from being surprised or embarrassed. In particular, if you are a foreigner who speaks a different language, you do not have to worry about malfunctions. In addition, even when the user wants to check for an item left behind in the room immediately after leaving the room, the system does not stop immediately, which is convenient for the user.

Even when it is determined that the user is to leave the room, as described in the first embodiment, the presence detection sensor 7 and the operation detection unit 8 detect that the user is in the room and that the human body 200 is in the room. judgment is made. In this regard, if a user is actually present, the electrical equipment or the like is kept activated. As a result, there is no inconvenience for the user.

Of course, as described above, if it is determined that the user is absent after taking these factors into consideration, the electrical equipment and the like are stopped. Users can save energy without extra effort.

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

Electric devices and electronic devices provided in the living room 101 are automatically started when the user is in the room and automatically stopped when the user is not in the room.

(Control via control unit)
As described above, the occupancy determination unit 6 processes automatic start-up and automatic stop of electrical equipment and electronic devices. Alternatively, as shown in FIG. 6, the room entrance/exit detection device 1 further includes a control unit 9, and upon receiving the determination result of the room presence determination unit 6, the control unit 9 controls automatic start and stop. It's okay.

The control unit 9 can perform detailed control and centralized control by controlling the automatic start and stop of the electrical equipment and the electronic device. In addition, since the control unit 9 is configured integrally with the electrical equipment and the electronic device, it is possible to perform control corresponding to replacement of the electrical equipment and the electronic device. Alternatively, control accuracy can be increased.

In this way, the control unit 9 may control automatic activation and automatic stop.

(Suspension procedure in absence)
In the absence state, the presence-in-room determining unit 6 or the control unit 9 automatically stops the electrical equipment and electronic devices provided inside the living room 101 . At this time, the occupancy determination unit 6 or the control unit 9 preferably performs automatic stop control in the order of illuminance reduction of the lighting equipment, stop of the video device, stop of the air conditioning equipment, and stop of the lighting equipment.

By performing stop control in this order, when the user leaves the room, the control is friendly to the user. When you leave the room, you can sense that the illuminance of the lighting device is going down, and you will be automatically stopped. In addition, since the lights do not turn off immediately, there is no inconvenience in checking for forgotten items when leaving the room. In addition, by turning off the video device and then turning off the air conditioner, it is possible to prevent the user from feeling hot or cold due to the air conditioner not working when leaving the room.

In particular, when leaving the room, it may take some time to actually leave the room after passing through the first sensor 2 and the second sensor 3 . In this case, it is possible to use the necessary electrical equipment for the work and time required for leaving the room. For this reason, it is possible to prevent the user from being inconvenienced when leaving the room, and it is possible to achieve both energy saving and convenience.

In this way, it is also preferable that the order of automatic stop is appropriately controlled.

As described above, the room entrance/exit detection device 1 according to Embodiment 2 can automatically start and stop the electric devices and electronic devices in the living room 101 according to whether the room is present or absent. As a result, energy saving and convenience for users or administrators can be enhanced. Of course, there are also effects such as cost reduction.

The entrance/exit detector described in Embodiments 1 and 2 is an example for explaining the gist of the present invention, and includes modifications and alterations within the scope of the gist of the present invention.
