Description

  The present invention relates to an outing determination system.

  In home care, there may be no response when the care staff visits and calls the care recipient. In some cases, the cared person has not responded because the cared person has gone out. However, the cared person cannot respond due to sudden illness or the like. In this case, since the care staff needs to respond quickly, it is necessary to check whether the care recipient (target person) is out or cannot respond due to sudden illness or the like. In order to cope with such a current situation, a system for determining whether or not the subject is out has been developed.

  As this system, a life watching system is known (Japanese Patent Laid-Open No. 2005-123727). In this system, a large number of human sensors are installed in a living area to determine whether a person has gone out. As a determination method, after a person is detected by a human sensor installed at the entrance, it is determined that the person has gone out when another human sensor in the living area does not detect the person within a certain period.

  However, in such a system, it is necessary to install human sensors at many places in the home of the care recipient, and the cost and labor for installation are required for each installation place. In addition, there is a possibility that false detection may occur depending on the flow line of the target person and the installation location of the sensor in the living area.

JP 2005-123727 A

  The present invention has been made in view of the circumstances as described above, and an object thereof is to provide an outing determination system that determines whether a subject has gone out without installing a large number of sensors and with few false detections. is there.

  The outing determination system of the present invention made to solve the above problems includes a door opening / closing detection unit that detects opening / closing of a door, a moving body detection unit that detects a moving body around the door, the door opening / closing detection unit, and a moving body detection. A processing unit that determines whether the person has gone out from the detection result of the unit, and when the moving unit is not detected inside the periphery of the door when the door is changed from the open state to the closed state, It is determined that the user has gone out.

  In the outing determination system, when the door is changed from the open state to the closed state, the target person has gone out in order to determine that the target person has gone out when no moving object is detected around the door. This can be determined with certainty. That is, when the door is changed from the open state to the closed state, the fact that no moving object is detected inside the periphery of the door means that the target person exists outside the other side of the periphery of the door. Therefore, it can be determined that the subject has gone out. In addition, the moving object detection unit that detects the moving object only needs to be able to detect the moving object around the door, and there is no need to provide a large number of detection units in consideration of the flow of the target person in the living area. Less is.

  Further, it is preferable that an operation unit is further provided, and the processing unit stops the determination of going out by an operation by the operation unit. As a result, when a third party other than the detection target person goes out, the third party other than the detection target person goes out of the door by operating the operation unit, and the moving object is not detected inside the door periphery. In addition, since it is determined that the subject has gone out, erroneous detection can be prevented.

  Furthermore, it is preferable to further include a storage unit that stores the detection result of the door opening / closing detection unit, the detection result of the moving object detection unit, and the determination result of the processing unit. Thereby, the past detection result and determination result can be confirmed, and a subject's action can be grasped.

  The outing determination system preferably further includes a stored information display unit that displays information stored in the storage unit. Thereby, a subject's action can be checked easily.

  In the above description, “around the door” means a location near the door where the subject is located when going out. “Inside the door” means the indoor side near the door.

  As described above, the outing determination system of the present invention can reliably determine whether the subject has gone out without providing a large number of detection units and with less risk of erroneous detection.

1 is a block diagram of an outing determination system according to a first embodiment of the present invention. It is the schematic of the going out determination system of FIG. 1, Comprising: (a) is the schematic when a subject does not go out, (b) is the schematic when the subject goes out. It is a block diagram of the going-out determination system of the second embodiment of the present invention.

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

[First embodiment]
<Outing determination system 1>
The going-out determination system 1 shown in FIG. 1 includes a door opening / closing detection unit 2, a moving object detection unit 3, and a processing unit 4, and the processing unit 4 based on detection results from the door opening / closing detection unit 2 and the moving object detection unit 3. However, it is determined whether the subject 5 has gone out.

  In the outing determination system 1, the door opening / closing detection unit 2 and the processing unit 4 are connected by wire or wirelessly, and information on opening / closing of the door 6 is transmitted. In addition, the moving object detection unit 3 and the processing unit 4 are also connected by wire or wirelessly, and information related to detection of the moving object is transmitted.

<Door open / close detection unit 2>
The door opening / closing detection unit 2 is a sensor that detects opening / closing of the door 6. The sensor is not particularly limited as long as the opening / closing of the door can be detected. As shown in FIG. 2, a sensor composed of a reed switch 2a and a magnet 2b can be employed. Thereby, it can install in the door 6 simply and cheaply.

  Further, the reed switch 2a and the magnet 2b are installed on the door frame 7 and the door 6, and specifically, the reed switch 2a and the magnet 2b are installed on the door frame 7 and an edge portion of the door 6 in contact with the door frame 7 ( 2), the reed switch 2a is turned on and off by the change in magnetic force from the magnet 2b due to the opening and closing of the door 6, and the opening and closing of the door 6 can be detected.

<Moving object detection unit 3>
The moving body detection unit 3 detects the presence or absence of a moving body within a predetermined range. Although the moving body detection part 3 is not specifically limited, It is sufficient if it can detect a moving body, and well-known sensors, such as a Doppler sensor, a thermo sensor, an image sensor, can be employ | adopted and a Doppler which can detect a moving body with high precision. A sensor is preferred.

  A well-known sensor can be used as the Doppler sensor, which emits a radio wave by microwaves or the like and detects the moving object based on the frequency of the radio wave reflected on the moving object. Further, the detection range of the Doppler sensor is the inside 8 around the door, and is a place where the subject is located in front of the door immediately before going out.

  The Doppler sensor may be installed at a location where the above-described detection range can be detected, and is not particularly limited. However, as shown in FIG. 2, the Doppler sensor can be installed on a wall surface 9 near the door.

  Moreover, in order to prevent the false detection by a small animal as an installation location of a Doppler sensor, an installation location can be adjusted according to the detection distance of a Doppler sensor. Furthermore, in order to prevent erroneous detection, the reflected wave received by the Doppler sensor may be filtered.

<Processing unit 4>
The processing unit 4 is a computer and determines whether or not the subject has gone out based on the detection results of the door opening / closing detection unit 2 and the moving object detection unit 3. As described above, the processing unit 4 is connected to the door opening / closing detection unit 2 and the moving object detection unit 3 in a wired or wireless manner, and receives detection results from the door opening / closing detection unit 2 and the moving object detection unit 3. The processing unit 4 is not particularly limited, but is stored in the same housing as the moving object detection unit 3.

  A processing method for determining whether or not the subject 5 has gone out will be described.

  When the door opening / closing detection unit 2 detects the opening / closing of the door 6, the door opening / closing detection unit 2 transmits a detection result to the processing unit 4. In addition, the moving object detection unit 3 (Doppler sensor) constantly emits radio waves and can detect moving objects, and transmits the detection result to the processing unit 4. When the processing unit 4 receives information that the detection result from the door opening / closing detection 2 is closed, the processing unit 4 checks the detection result of the moving object received from the moving object detection unit 3. When the moving object is detected (when detected in the state of FIG. 2A), the subject 5 is not determined to have gone out, while when the moving object is not detected (FIG. 2B). If it is detected in the state), it is determined that the subject 5 has gone out.

  The determination result by the processing unit 4 is not particularly limited, but can be displayed in a lamp on the casing in which the processing unit 3 is stored.

<Advantages>
In the outing determination system 1, when the door detection unit 2 detects the closing of the door 6, if the moving object detector 3 does not detect a moving object inside the door 8, the processing unit 4 Since it can be determined that 5 has moved to the outside of the door 6 and has gone out, it can be reliably determined that the subject 5 has gone out. In addition, the moving object detection unit 3 need only be installed near the door, and need not be installed at many other locations.

  Furthermore, since the moving object detection unit 3 is installed so that the inner side 8 around the door is a detection target, when the target person 5 returns home or when the target person opens or closes the door when visiting a third party, Since the subject 5 is detected on the inner side 8 of the object, there is little risk of erroneous detection.

[Second Embodiment]
Next, the outing determination system 11 as the second embodiment will be described. In the description of the second embodiment, the same reference numerals are used for those having the same configuration as the first embodiment, and the detailed description thereof may be omitted.

<Outing determination system 11>
3 includes a door opening / closing detection unit 2, a moving object detection unit 3, a processing unit 14, an operation unit 15, a storage unit 16, and a storage information display unit 17, and includes the door opening / closing detection unit 2 and the moving object detection unit. Based on the detection result from the unit 3, the processing unit 14 determines whether or not the subject has gone out. In the outing determination system 11, the processing unit 14 stops the determination of going out by operating the operation unit 15. Further, in the outing determination system 11, the detection result of the door opening / closing detection unit 2, the detection result of the moving object detection unit 3, and the determination result by the processing unit 14 are stored in the storage unit 16, and the stored information is stored by the storage information display unit 17. Is displayed.

  In the outing determination system 11, the door opening / closing detection unit 2 and the processing unit 14 are connected by wire or wirelessly, and information on opening / closing of the door is transmitted. In addition, the moving object detection unit 3 and the processing unit 14 are also connected by wire or wirelessly, and information related to detection of the moving object is transmitted. Further, the processing unit 14 and the operation unit 15 are connected by wire or wirelessly, and the information is transmitted to the processing unit 14 when the operation unit 15 is operated.

  In the outing determination system 11, the processing unit 14, the storage unit 16, and the stored information display unit 16 are connected, and the determination result by the processing unit 14 and the information stored in the storage unit 16 are transmitted.

<Processing unit 14>
The processing unit 14 is a computer, and determines whether or not the subject has gone out from the detection results of the door opening / closing detection unit 2 and the moving object detection unit 3. As described above, the processing unit 14 is connected to the door opening / closing detection unit 2 and the moving object detection unit 3 by wire or wirelessly, and receives detection results from the door opening / closing detection unit 2 and the moving object detection unit 3. The processing unit 14 is not particularly limited, but is stored in the same housing as the moving object detection unit 3 and the storage unit 16.

  A processing method for determining whether or not the subject has gone out will be described.

  When the door opening / closing detection unit 2 detects the opening / closing of the door, the door opening / closing detection unit 2 transmits a detection result to the processing unit 14. In addition, the moving object detection unit 3 is in a state in which a radio wave is constantly emitted and a moving object can be detected, and the detection result is transmitted to the processing unit 14. The processing unit 14 confirms the detection result of the moving object received from the moving object detection unit 3 when the detection result regarding the opening / closing of the door from the door opening / closing detection 2 is closed, and there is no detection of the moving object. It is determined that the subject has gone out.

  On the other hand, when an operation unit 15 described later is operated and the information is transmitted to the processing unit 14, the processing unit 14 stops determining whether or not the user has gone out. Therefore, when the processing unit 14 receives the information indicating that the detection result regarding the opening / closing of the door transmitted from the door opening / closing detection 2 is closed, the detection result of the moving object received from the moving object detection unit 3 does not detect the moving object. Even in the case of the result, when the operation unit 15 is operated, it is not determined that the subject is out.

  The processing unit 14 stores information on whether or not the subject has gone out in the storage unit 16 described later. As the information to be stored, in addition to the determination result of whether or not the user has gone out, the detection result of the door opening / closing detection unit 2 and the moving object detection unit 3 and information regarding the determined date and time can also be stored. In addition, as a timing memorize | stored in the memory | storage part 16, you may memorize | store in the memory | storage part 16 not only when it determines with going out but for every opening / closing timing of a door.

<Operation unit 15>
The operation unit 15 is used to stop the determination of going out, and to prevent the target person from being determined to have gone out when a third party other than the target person goes out of the door. When a third party other than the target person goes out of the door, in order to prevent a third party other than the target person from being determined to be out of the target person, a third party other than the target person or the like operates the operation unit 16. The judgment of going out is stopped by operating.

  The operation unit 15 is not particularly limited, but an operation button can be employed. A signal is transmitted to the processing unit 14 by the operation of the operation unit 15. Thereby, the processing unit 14 stops the determination of going out.

  Further, the installation location of the operation unit 15 is not particularly limited, but it is preferably installed near the door. Thereby, operation to the operation part 15 becomes easy when a third party other than the target person goes out. In addition, the operation unit 15 is not particularly limited, but may be disposed in the same casing as the processing unit 14 or may be disposed in different places in different casings.

<Storage unit 16>
The storage unit 16 is a memory and stores information on whether or not the subject has gone out. Although it does not specifically limit as the memory | storage part 16, A well-known thing is employable.

  The information stored in the storage unit 16 includes the determination result of whether or not the subject has gone out as described above, the detection results of the door opening / closing detection unit 2 and the moving object detection unit 3, and the determined date and time. The open / closed state of the door can be stored. Furthermore, the history of past determination information can be stored in the storage unit 16.

  The storage unit 16 is not particularly limited, but can be stored in the same housing as the processing unit 14.

<Storage information display unit 17>
The stored information display unit 17 displays information stored in the storage unit 16 via the processing unit 14. The stored information display unit 17 is not particularly limited, but a terminal device connected to the processing unit 14 and the storage unit 16 via wireless can be employed.

  Although it does not specifically limit as a terminal device, A mobile telephone and a portable information terminal are employable. Thereby, the information of the memory | storage part 16 can be confirmed easily. Moreover, the connection from the terminal device to the storage unit 17 can use a known security technique from the viewpoint of crime prevention.

  In addition, the structure of the door opening / closing detection part 2 and the moving body detection 3 can employ | adopt the thing similar to said 1st embodiment.

<Advantages>
In the outing determination system 11, when the door opening / closing detection unit 2 detects the closed state of the door, if the moving body detection unit 3 does not detect a moving body inside the periphery of the door, the processing unit 14 Since it can be determined that the user has moved out of the door and has gone out, it is possible to reliably determine whether the subject has gone out. In addition, the moving object detection unit 3 need only be installed near the door, and need not be installed at many other locations.

  Furthermore, since the moving object detection unit 3 is installed so that the inside of the periphery of the door becomes a detection target, when the target person returns home or when the target person opens or closes the door when visiting a third party, the inside of the door periphery Therefore, there is little risk of false detection.

  Further, in the outing determination system 11, since the storage unit 16 stores the detection result, the determination result, and the like, even if the time has elapsed since opening and closing of the door, the subject can go out by checking the information in the storage unit 16. It can be confirmed whether or not. The stored information display unit 17 can easily store the information.

  In addition, since the determination of going out is stopped when operated by the operation unit 15, a third party other than the target person operates the operation unit 15 when going out, so that the third party other than the target person goes out. It is possible to prevent erroneous detection without determining that the user has gone out.
