FIG. 4 (a) is an explanatory view of a detection operation when the rotating body is at the 0 ° position, and FIG. 4 (b) is when the rotating body is at the position rotated ± 180 °. 4 (c) is an explanatory view of the watching area of the human sensor at the time of normal rotation and reverse rotation, and FIG. 4 (d) is an explanation of the watching area of the temperature sensor at normal rotation and reverse rotation. FIG. FIG. 5A is an explanatory view of detection by a human sensor, and FIG. 5B is an explanatory view of detection by a temperature sensor. FIG. 1 is a system diagram of a wide area surveillance system including a surveillance system according to an embodiment of the present invention.

  Subsequently, a watching system and a wide area watching system according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the watching system 1 at least includes a watching apparatus 10 and a vital sign detection unit 20. Then, the vibration sensing device 30 and the door sensor 40 are provided according to the situation of the watching target.

  The watching system 1 watches a person (hereinafter referred to as a “watching target person”) who is in a preset area (hereinafter referred to as a “watching field”), and an abnormality (death, illness, injury or injury) of the watching target person. ) To discover early.

  The watching area is set, for example, in a single room in a single-family home or an apartment house where a watching target person lives. The watching target wears the vital sign detection unit 20. Moreover, in the present embodiment, the watching area can be set within a radius of 20 m centering on the watching apparatus 10. Note that the above is an example, and the watching area is not limited to this range, and may be a wider area or a narrow area.

  The watching target is, for example, an elderly person living alone, a disabled person, or a care recipient of a nursing home for the elderly. In the present specification, for the sake of concreteness of the explanation, the watching target is described as being an elderly person living alone. In the present specification, “normal” and “abnormal” are normal when the watching target is in a normal life condition, and are different from normal conditions such as death, illness and injury. It explains collectively as abnormality. And it is assumed that watching target person is normal at the start of watching.

  The watching apparatus 10 has a robot's face-like appearance (see FIG. 2) in order to make the watching target person more familiar. The watching apparatus 10 watches the state of the watching target in the watching area and detects it based on the temperature of the watching target.

  The vital sign detection unit 20 is for the watching target to wear. The vital sign detection unit 20 wirelessly transmits the signal to the monitoring apparatus 10 constantly by watching the vital sign related to the body of the watching target. A range in which the watching apparatus 10 can detect the vital sign detection unit 20 by radio is set within a radius of 20 m. In other words, this watching area is within a maximum radius of 20 m centering on the watching apparatus 10. When the watching target goes out of this watching area, the radio can not be communicated and it can be detected that the watching area has gone out. The data from the vital sign detection unit 20 may be registered in the smartphone, and the data may be sent to the watching apparatus 10 via the smartphone.

  The vital signs (vital signs) mean "signs that appear when maintaining life", and appear when the heart beats and blood pressure is kept above a certain value, and when breathing and maintaining body temperature. Specifically, they are the blood pressure, pulse rate, respiration rate, body temperature, and electrocardiogram of the person being watched over. Such a vital sign detection unit 20 is, for example, an electrocardiograph 20a, a clock 20b, a wrist band 20c or the like having a vital sign detection function.

  The electrocardiograph 20a detects an electrocardiogram and, after modulating the signal, constantly transmits the signal to the watching apparatus 10 by low power radio. The blood pressure other than the electrocardiogram, the pulse rate, the respiration rate, and the body temperature may be detected to be a vital sign including a plurality of pieces of information.

  The watch 20 b is a wristwatch type worn on the wrist, for example, detects blood pressure and pulse rate, and transmits constantly to the watching apparatus 10 by low power radio after modulation of a signal. Moreover, it is good also as a vital sign which detected a respiration rate other than a blood pressure and a pulse rate, and a body temperature, and contained several information.

  The wristband 20c is of a type worn on the wrist or ankle, detects blood pressure and pulse rate as vital signs, and constantly transmits the signal to the watching apparatus 10 by low power radio after modulation of the signal. Moreover, it is good also as a vital sign which detected a respiration rate other than a blood pressure and a pulse rate, and a body temperature, and contained several information. The wristband 20c is always worn on the ankle with a relatively small burden, especially for watching people who have symptoms of dementia, such as old people.

  The vibration-sensing device 30 has a function of detecting a vibration, and after the modulation of the vibration signal, transmits constantly to the watching device 10 by low power radio. The vibration sensing device 30 is attached to the equipment 30 a in the watching area. The equipment 30a is, for example, a bed, a table, a chair, furniture and the like. When the monitoring device 10 senses an abnormal vibration, the monitoring device 10 determines that the person to be watched over falls in the vicinity of the facility 30a or collides with the facility 30a.

  The door sensor 40 has, for example, a function of detecting opening and closing of a room door, and constantly transmits the monitoring signal to the monitoring device 10 by low power radio after modulation of the opening and closing signal. For example, it is detected whether the user has entered or left the room. As described later, if there is no change for a long time after leaving the room, it is judged as abnormal. In addition, the door sensor which detects opening and closing of a toilet door and opening and closing of a bath door can also be set, and it detects whether it entered into a toilet or a bath, or it pulled out from a toilet or a bath. When the watching target person detects the opening and closing of the door when entering and leaving the toilet or bath within a predetermined time, the watching target person can be determined as normal.

  Subsequently, the detail of the watching apparatus 10 will be described. The watching apparatus 10 is provided with a base portion 10a, a rotating body 10b, a human sensor 10c, a temperature sensor 10d, and an antenna 10e as a mechanical system, as shown in the external view of FIG. As an electric system, as shown by the block diagram in FIG. 3, a human sensor 10c, a temperature sensor 10d, an antenna 10e, a memory unit 10f, a speaker 10g, an external communication unit 10h, a display unit 10i, a wireless unit 10j, a motor drive The controller 10 includes a unit 10k, a motor 10l with an angle sensor, and a control processing unit 10m.

  The base portion 10a is a mechanical base, and is formed to be stable at an appropriate weight when installed on, for example, a top plate of a furniture, as a position that can overlook the watching area.

  The rotating body 10 b is configured to rotate with respect to the base portion 10 a by a rotation support mechanism (not shown). For example, the antenna 10e is configured to double as a rotation support shaft of the rotating body 10b.

  The human sensor 10c is connected to the control processing unit 10m, and more specifically, is a pyroelectric infrared sensor. When a pyroelectric infrared sensor receives infrared light emitted from a watching target, it absorbs thermal energy, causing a change in spontaneous polarization, and charge is induced on the surface in proportion to the amount of change (pyroelectric infrared sensor Effect) to sense infrared rays. This feature is used to detect the movement of the watching target (see the change). By using a pyroelectric infrared sensor, it is possible to detect watching subjects even in the dark. In addition, since the pyroelectric type senses the change of infrared rays, if there is no change, it does not output even if there is a heat source. The human sensor 10c outputs a detection signal to the control processor 10m. This detection signal is used for watching processing described later.

  The temperature sensor 10d is connected to the control processing unit 10m, and performs detection of a person by infrared rays. For example, it is thermography which analyzes the infrared rays emitted from the object and expresses the heat distribution as an image represented as a figure. The temperature sensor 10d outputs a detection signal including an image to the control processing unit 10m. This detection signal is used for watching processing described later.

  The antenna 10 e is an antenna for wirelessly communicating with the vital sign detection unit 20 (electrocardiograph 20 a, watch 20 b, wrist band 20 c), the vibration sensing device 30, and the door sensor 40. The antenna is configured to protrude from the top of the rotating body 10b. The antenna 10 e wirelessly receives detection signals from the vital sign detection unit 20 of the watching target person, the vibration sensing device 30, and the door sensor 40 in the watching area set in advance. Communication between the watching apparatus 10 and the vibration sensing apparatus 30 and the door sensor 40 is wired, and only communication between the watching apparatus 10 and the vital sign detection unit 20 attached to the watching target is wireless communication. good.

  The memory unit 10f is connected to the control processing unit 10m, and registers voice data of an inquiry by the family of the watching target and image data of the family of the watching target and the like. Note that moving image data in which image data and audio data are integrated may be used. In this case, audio data extracted from the moving image data is output from the speaker 10g, and image data of the moving image extracted from the moving image data is displayed on the display unit 10i.

  The speaker 10 g is connected to the control processing unit 10 m. The control processing unit 10m generates a drive signal based on the audio data read from the memory unit 10f, and causes the speaker 10g to output an audio.

  The external communication unit 10 h is connected to the control processing unit 10 m. The external communication unit 10 h is a communication unit for connecting to the network 200 shown in FIG. For example, it is a circuit device for connecting to the Internet line. The control processing unit 10m performs data communication with an external device via the network 200 via the external communication unit 10h.

  The display unit 10i is connected to the control processing unit 10m. The control processing unit 10m generates a drive signal based on the image data read from the memory unit 10f, and causes the display unit 10i to display and output.

  The wireless unit 10 j is connected to the control processing unit 10 m. The wireless unit 10j is a wireless signal transmitted from the vital sign detection unit 20 (electrocardiograph 20a, clock 20b, wristband 20c), the vibration sensing device 30, and the door sensor 40 by the small power wireless, which are within the watching area set in advance. The signal is received through the antenna 10e and then demodulated to generate a detection signal, and the detection signal is transmitted to the control processing unit 10m. The control processing unit 10m performs a watching process as described later from these detection signals.

  The motor drive unit 10k is connected to the control processing unit 10m and the motor 10l with an angle sensor. The motor drive unit 10k rotationally drives the angle sensor-equipped motor 10l based on the control from the control processing unit 10m. Further, the motor drive unit 10k outputs angle data from the motor with angle sensor 10l to the control processing unit 10m.

  The angle sensor attached motor 10 l applies a rotational force to the rotating body 10 b supported by the rotation support mechanism. The control processing unit 10m performs angle control based on angle data output from the angle sensor-equipped motor 10l, and acquires position information of the person to be watched from the angle data.

  The control processing unit 10m extracts various data from the signals from the vital sign detection unit 20, the vibration sensing device 30, the door sensor 40, the human sensor 10c, and the temperature sensor 10d, and based on these data, a determination method to be described later. The watching target judges "normal" or "abnormal". For example, when the detection signal is detected from the human sensor 10c, the watching target person is moving, and it may be determined that the watching target person is normal. The whole structure of the watching system 1 is such.

  Subsequently, the watching by the watching system 1 will be described. First, the point of detecting the state of the watching target person in the watching area defined in advance by the human sensor 10c and the temperature sensor 10d which are the state detecting unit will be described. For example, when the watching area is one room, the watching apparatus 10 is arranged at a position where the whole room can be seen, for example, on furniture.

  The control processing unit 10m controls the motor drive unit 10k to rotate the angle sensor-equipped motor 10l. The rotating body 10b rotates 180 ° forward from the 0 ° position in FIG. 4 (a) and rotates to the position in FIG. 4 (b), and then reversely returns to the 0 ° position in FIG. 4 (a) . In this case, the human sensor 10c detects the human feeling area during normal rotation as shown in FIG. 4C, and the temperature sensor 10d detects the temperature during normal rotation as shown in FIG. 4D. Detect detection area.

  Then, the rotating body 10b is rotated 180 ° reversely from the position of 0 ° in FIG. 4A to the position of FIG. 4B, and is rotated forward from here to the position of 0 ° in FIG. 4A. Back to In this case, the human sensor 10c detects a human feeling area at the time of reverse rotation as shown in FIG. 4C, and the temperature sensor 10d detects a temperature detection area at the time of reverse rotation as shown in FIG. To detect The rotating body 10a repeats the same operation thereafter. As a result, the temperature of the watching target present in a predetermined watching area is detected.

  During this watching, as shown in FIG. 5 (a), the motion sensor 10c detects the movement of infrared rays generated from the watching target 50, and as shown in FIG. 5 (b), from the watching target 50 The temperature sensor 10d detects the infrared rays generated. The control processing unit 10m specifies the presence or absence of the operation of the watching target and the temperature of the watching target based on the detection signal. The watching apparatus 10 records the presence / absence of the watching target person's motion and the angle data θ when the temperature is detected, and specifies the position of the watching target person 50. If the same angle is detected at the time of repeated detection, it can be determined that the watching target 50 is located at the same position.

  Further, when the watching target person 50 is located at the same place but the operation is stopped, the detection signal is detected from the temperature sensor 10d, but the detection signal is not detected from the human sensor 10c. When the watching target person 50 is moving, a detection signal is detected from the temperature sensor 10d, a detection signal is also detected from the human sensor 10c, and the angle data θ changes. The guard by the state detection unit is such.

  Subsequently, watching by the watching device 10 using the detection signals from the state detecting unit (the human sensor 10c and the temperature sensor 10d) and the vital sign detecting unit 20 will be described.

  First, the determination at the normal time will be described. The state detection unit (the human sensor 10c and the temperature sensor 10d) and the vital sign detection unit 20 output a detection signal. The control processing unit 10m inputs these detection signals. The control processing unit 10m determines that a watching target person is present in the watching area based on detection signals from the state detection unit (the human sensor 10c and the temperature sensor 10d). For example, when the temperature sensor 10d detects the temperature equivalent to the normal heat of the watching target and the motion sensor 10c detects the operation of the watching target, it is determined that the watching target is present and moving. At this temperature detection time, in addition to the temperature equivalent to the normal heat of the watching target person, the watching target person is also present and moving when ordinary special living temperatures such as smoking, meals, drinks are detected in the watching area I will judge.

  Moreover, although a change may not be detected from the human sensor 10c, for example, an old man may not move at all even if he is not sleeping and may not move at all, and the control processing unit 10m generates a temperature equivalent to a flat heat from the temperature sensor 10d. If there is a detection signal of (1), it is determined that a watching target is present and in a normal state. The determination criteria can be determined by investigating the characteristics of the watching target when the watching apparatus 10 is installed. This increases the accuracy of the judgment.

  Subsequently, based on the detection signal from the vital sign detection unit 20, the control processing unit 10 m determines whether the vital sign of the watching target is normal or not. The vital sign of the watching target person acquired in advance is registered, and it is determined that the vital sign is normal when there is no remarkable change from the normal value as compared with the vital sign.

  Based on the detection signals from the state detection unit (the human sensor 10c and the temperature sensor 10d) and the vital sign detection unit 20, the control processing unit 10m determines that a watching target is present and the vital sign is normal. When it can be judged, it is judged that the watching target is normal, and the judgment is ended. In addition, the watching system 1 determines that this non-normal state is abnormal as described later.

  Subsequently, the determination at the time of abnormality will be described. First, we will judge about life abnormalities. In the control processing unit 10m, it is determined that there is a person to be watched over in the watching area based on the detection signal from the state detecting unit (the human sensor 10c and the temperature sensor 10d). If you do not detect the presence of the watch target person in the same area of the watch area (the position data is almost the same) (if the movement disappears and the temperature decreases), vital sign detection Based on the detection signal from the unit 20, the health condition of the watching target is confirmed. Here, if the health condition of the person being watched over is good, “blood pressure, pulse rate, respiration rate, temperature, electrocardiogram” is normal with no noticeable change from the normal value compared to the registered vital signs. If the vital sign of the watched person is in the same place, that is, “blood pressure, pulse rate, respiratory rate, body temperature, electrocardiogram” is out of the usual value compared to the registered vital sign. If it shows an outlier with a change, it is determined that the life of the watching target is abnormal (that is, it has died). The control processing unit 10m communicates the abnormality to the outside through the external communication unit 10h. In this way, it is possible to judge the death and to promptly detect and notify.

  Then, it judges about the abnormality by the eyelid. The control processing unit 10m detects a state in which there is no watching target person (no movement, no temperature) in the watching area based on detection signals from the state detection unit (the human sensor 10c and the temperature sensor 10d). When the detection signal can not be continuously received from the vital sign detection unit 20 for a predetermined period, it is determined that the watching target has left the watching area (that is, it is overwhelmed). At this time, the first time when reception is interrupted from the vital sign detection unit 20 is determined as the leaving time. For example, when T minutes have passed since the leaving time, that is, the heel start time, it is estimated that the watching target is within the radius aT [m], assuming that the watching target walks at a minute per minute [a / m]. It has the advantage of being able to narrow down the search range of The control processing unit 10m communicates with the outside via the external communication unit 10h about the abnormality and the leaving time. In this way, it is possible to determine the range of search and search.

  In addition, it may be considered that the watching target person enters the toilet or bath and leaves the watching area. In this case, if the watch target person is no longer watched at the specific position (predetermined angle data) in front of the toilet or bath (there is no movement. There is no temperature. It can be determined that you have taken a bath. Such determination logic may be added.

  Subsequently, another judgment method will be described with respect to the abnormality judgment by the habit. Here, a door sensor 40 that detects the opening and closing of the door that goes out of the watching area is also used. After detecting that the door 40a (FIG. 1) is opened and closed based on the detection signal from the door sensor 40, the control processing unit 10m is based on the detection signal from the state detection unit (the human sensor 10c and the temperature sensor 10d). When the presence of the person being watched can not be detected in the watching area (no movement and no temperature) and the detection signal can not be continuously received from the vital sign detection unit 20 for a predetermined period, the person being watched Judges that he has left the watch area (that is, hesitation). The control processing unit 10m communicates with the outside via the external communication unit 10h about the abnormality and the leaving time. Also in this case, the time when the detection signal from the door sensor 40 is received or the first time when the reception from the vital sign detection unit 20 is stopped is determined as the leaving time. In this way, it is possible to determine the range of search and search.

  In addition, it may be considered that the watching target person enters the toilet or bath and leaves the watching area. Therefore, a door sensor 40 is also installed to detect the opening and closing of the toilet or bath door. The control processing unit 10m detects that the toilet or bath door has been opened or closed based on a detection signal from the door sensor 40 of the toilet or bath, and the watch target person watches over at the specific position before the toilet or bath If it does not exist (no movement, there is no temperature), it is judged that you have entered the toilet or bath rather than a whistle. Such determination logic may be added.

  Then, judge about the abnormality of health. The control processing unit 10m determines that there is a person to be watched over in the watching area based on the detection signal from the state detection unit (the human sensor 10c and the temperature sensor 10d) (there is movement and there is temperature). And the vital sign of the person being watched over is poor based on the detection signal from the vital sign detection unit 20 (blood pressure, pulse rate, respiratory rate, body temperature, and electrocardiogram compared with the registered vital sign. There is a marked change from the value. For example, when it is judged that the blood pressure or body temperature is high, the pulse rate or the respiration rate is high, the watching target is ill or injured and the health is abnormal. I will judge. The control processing unit 10m communicates the abnormality to the outside through the external communication unit 10h. In this way, health abnormalities can be determined and detection and notification can be made quickly.

  Then, judge about the abnormality of health. Here, it is an abnormality determination which also uses the vibration sensing device 30 which detects the vibration of the installation 30a. The control processing unit 10m determines that the watching target falls or collides when it senses an abnormal vibration based on the detection signal from the vibration sensing device 30, and the state detection unit (the human sensor 10c and the temperature sensor 10d) It is judged that there is a target person to be watched in the watching area based on the detection signal from (the movement is present and there is a temperature), and based on the detection signal from vital sign detection unit 20 When it is determined that the vital sign is poor, it is determined that the watching target is injured and the health is abnormal. The control processing unit 10m communicates the abnormality to the outside through the external communication unit 10h. In this way, health abnormalities can be determined and detection and notification can be made quickly.

  In addition, it is made to call from the watching apparatus 10 at the time of abnormality. The voice data of the family or the like of the person being watched over is read from the memory unit 10f, and for example, a content such as "Are you OK?" Is output from the speaker 10g. Further, at this time, the display unit 10i displays the face of the watching subject's family or the like to give a sense of closeness. If it is detected that the human sensor 10c has moved in response to the call, it is determined that it is not abnormal but normal, and normal watching continues. If it does not move, it communicates to the outside through the external communication unit 10 h. In addition, it is connected communicably with the television in the watching area, and this watching television displays the face of the watching subject's family etc. and outputs contents such as "Is it all right?" From the speaker of the television You may

  And although this is an appeal, it may be performed immediately when the vibration sensing device 30 detects a vibration by hitting furniture such as a bed, a table, a chair, etc. In addition, when the door sensor 40 detects opening and closing It may be done immediately. The watching system 1 is like this.
