JP 2003-51079 A

  However, in the conventional deaf person detection system, the detection accuracy of the door detection device is low, and there is a possibility that the deaf person cannot be detected with good accuracy.

  For example, when an acceleration sensor that detects the movement of the door is used as the door detection device, there is a possibility that the movement of the door cannot be detected when a person with weak physical strength opens the door slowly.

  In addition, when a magnetic sensor that detects the position of the door is used for the door detection device, there is a risk that the movement of the door may be detected by mistake when the door opens due to vibration or wind. .

  Therefore, according to the first aspect of the present invention, in the deception detection system in which a signal transmitted from the door detection device for detecting that the door has been opened is received by the management device and the deception is detected, the door detection is performed. The device decided to detect the opening of the door using multiple types of sensors.

  Further, in the present invention according to claim 2, in the present invention according to claim 1, the door detection device uses a sensor for detecting the movement of the door and a sensor for detecting the position of the door.

  Further, in the present invention according to claim 3, in the present invention according to claim 2, an acceleration sensor is used as a sensor for detecting the movement of the door, and a geomagnetic sensor is used as a sensor for detecting the position of the door. .

  And in this invention, there exists an effect described below.

  That is, in the present invention, in the deception detection system for detecting a deaf person by receiving a signal transmitted from the door detection apparatus for detecting that the door has been opened by the management apparatus, the door detection apparatus has a plurality of types. Because the sensor is used to detect that the door has been opened, multiple types of sensors can function in a complementary manner to detect that the door has been opened. It can be carried out with good accuracy.

  In particular, as a door detection device, when a sensor for detecting the movement of the door and a sensor for detecting the position of the door are used, different states (movement and position) of the door can be detected. The detection of the deaf person can be performed with good accuracy and goodness.

  In addition, when an acceleration sensor is used as a sensor for detecting the movement of the door and a geomagnetic sensor is used as a sensor for detecting the position of the door, even when a person with weak physical strength opens the door slowly or Even when the door is opened due to the influence of vibration, wind, or the like, it is possible to satisfactorily determine whether or not the door has been opened by a deaf person.

Explanatory drawing which shows the deaf person detection system which concerns on this invention.

  The specific configuration of the deception detection system according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a deaf person detection system 1 includes a door detection device 2 that is installed on a door provided indoors or outdoors such as a home or a facility and detects that the door has been opened, and its door detection. It is comprised with the management apparatus 3 for receiving the signal transmitted from the apparatus 2 by radio | wireless or a wire, and detecting a deaf person. Here, the door detection device 2 is installed for each different door, and the respective signals from the plurality of door detection devices 2 are collectively received and managed by the management device 3.

  In the door detection device 2, a plurality of types (here, two types) of sensors 5 and 6 are connected to the controller 4, and a transmitter 7 is connected to the controller 4.

  The controller 4 controls the sensors 5, 6 and the transmitter 7, and transmits the physical values detected by the sensors 5, 6 to the management device 3 by the transmitter 7.

  The sensors 5 and 6 may be a plurality of types of sensors having different physical values to be detected. For example, a sensor that detects the movement of the door or a sensor that detects the position of the door can be used. Here, the sensor that detects the movement of the door corresponds to a sensor that detects a physical value such as the movement speed, rotation speed, movement acceleration, or rotation acceleration of the door when the door is opened. Etc. can be used. In addition, the sensor that detects the position of the door is a sensor that detects a physical value such as the absolute position or relative position of the door when the door is opened, or that the door is not in the closed position. However, a geomagnetic sensor, a magnetic sensor, an optical sensor, or the like can be used. Here, an acceleration sensor that is a sensor that detects the movement of the door is used as the sensor 5, and a geomagnetic sensor that is a sensor that detects the position of the door is used as the sensor 6.

  The transmitter 7 may be any device as long as it can transmit a signal to the management device 3 in a predetermined format. The transmitter 7 may receive not only the signal but also a signal for controlling the controller 4.

  The door detection device 2 is attached to a portion that moves when the door is opened, and detects whether the door has been opened using a plurality of types of sensors 5 and 6 simultaneously or sequentially, and uses the signal as a signal for the transmitter 7. To the management device 3.

  On the other hand, the management device 3 connects the receiver 9 to the controller 8, connects the input device 10 and the output device 11 to the controller 8, and further connects the transmitter 12 to the controller 8.

  The controller 8 controls the receiver 9, the input / output devices 10 and 11, and the transmitter 12. The controller 8 receives the signal transmitted from the door detection device 2 and receives the input device 10 as necessary. Is received, and output to the output device 11 and transmission from the transmitter 12 is performed.

  The receiver 9 only needs to be able to receive a signal of a predetermined format transmitted from the door detection device 2, and may be able to transmit not only a signal but also a signal for controlling the door detection device 2. .

  The input device 10 may be a device that accepts an input from a user as necessary, and may be a single switch such as an operation start button or a reset button, or a key switch such as a numeric keypad or a keyboard.

  The output device 11 may be any device that can notify the user as necessary, and may display only numbers such as a 7-segment LED, or may display characters such as a liquid crystal display, Further, it may be one that emits a single sound such as a buzzer or one that emits sound such as a speaker.

  The transmitter 12 only needs to be able to transmit to a portable terminal such as a user in a remote place as necessary, and may be able to receive a signal or the like for enabling remote operation.

  The management device 3 analyzes the signal transmitted from the door detection device 2 with the controller 8 and, when determining that the door has been opened, outputs the output device 11 to notify the user. At that time, a specific remote person may be notified from the transmitter 12.

  Then, the management device 3 uses the physical values detected by the plurality of types of sensors 5 and 6 provided in the door detection device 2 to determine whether the door provided with the door detection device 2 has been opened or not (in the middle of Presence or absence).

  For example, when the physical value detected by the sensor (acceleration sensor (sensor 5)) that detects the movement of the door is equal to or greater than a predetermined value, the management device 3 immediately determines that the door has been opened. If the physical value detected by the sensor that detects the movement of the door (acceleration sensor (sensor 5)) is less than a predetermined value, the door position is detected without immediately determining that the door has been opened. It is determined that the door is opened only when the physical value detected by the sensor (geomagnetic sensor (sensor 6)) is a predetermined value or more. Thereby, even if a person with weak physical strength opens the door slowly, it can be detected with high accuracy.

  In addition, when the physical value detected by the sensor (geomagnetic sensor (sensor 6)) that detects the position of the door is less than a predetermined value, the management device 3 immediately determines that the door is not opened. If the physical value detected by the door position sensor (geomagnetic sensor (sensor 6)) is greater than or equal to a predetermined value, the door movement is detected without immediately determining that the door has been opened. It is determined that the door is opened only when the physical value detected by the sensor (acceleration sensor (sensor 5)) is within a predetermined range (a range of values considered to be human). Thereby, even when the door is opened due to the influence of vibration or wind, it can be accurately detected.

  As described above, the management apparatus 3 can perform detection with high accuracy by using a plurality of types of sensors.

  Further, the management device 3 asks the subject who may become a deaf person to actually open and close the door to which the door detection device 2 is attached, and at that time the physical value (one time Value, a plurality of average values, or a value (range) having a certain range may be stored in advance as the characteristic value of the subject, and the characteristic value of the subject and the door detection device 2 It is also possible to determine whether or not the door has been opened by the subject by comparing with the signal transmitted from. In addition, characteristic values of persons other than the target person are stored in advance, and these characteristic values are compared with the signal transmitted from the door detection device 2 to determine whether the door is opened or not. You can also identify who opened. Also in this case, detection can be performed with high accuracy by using a plurality of types of sensors in the management device 3.

  As described above, the deaf person detection system 1 is a system that receives a signal transmitted from the door detection device 2 for detecting that the door is opened by the management apparatus 3 and detects the deaf person. Thus, the door detection device 2 uses a plurality of types of sensors 5 and 6 to detect that the door has been opened.

  Therefore, in the deception detection system 1 configured as described above, the plurality of types of sensors 5 and 6 can function complementarily to detect that the door has been opened, and the deception of the deception can be accurately and satisfactorily performed. Can do.

  In particular, the deaf person detection system 1 has a configuration using a sensor 5 for detecting the movement of the door and a sensor 6 for detecting the position of the door as the door detection device 2.

  Therefore, the deaf person detection system 1 having the above-described configuration can detect different states (movement and position) of the door, and can detect the deaf person with higher accuracy and better.

  In addition, the deaf person detection system 1 uses an acceleration sensor as the sensor 5 that detects the movement of the door, and uses a geomagnetic sensor as the sensor 6 that detects the position of the door.

  Therefore, in the deaf person detection system 1 configured as described above, even when a person with weak physical strength opens the door slowly or when the door is opened due to the influence of vibration, wind, etc., It can be determined well whether or not the door has been opened.
