Description

  The present invention relates to a non-contact watching system, and more particularly to a non-contact watching system capable of comprehensively watching the biological information of a watched person and the environmental state of a living room.

Along with the declining birthrate and aging population, the number of elderly living alone has increased, and families living apart often cannot understand the status of the elderly while caring about the health status of the elderly living alone. For this reason, even if an elderly person falls down due to a sudden illness, the allowance may be delayed due to a lack of awareness or a lack of understanding of the situation.
For this reason, various watching methods have been studied.

Patent Document 1 is a system in which a plurality of vibration sensors are installed in the living space of a watched person to detect vibrations generated along with the activities of the watched person and watch whether the watched person is working properly. For example, when the watched person is quietly relaxing in one room, it is difficult to detect a clear vibration that detects the activity, so it is impossible to detect whether the person is simply resting or is in a bad condition.
Patent Document 2 discloses a technology that uses an infrared sensor to detect a movement of a person to be watched and can send an alarm to a family member when there is no movement for a certain period of time. For example, even if the watching target person lies down and stays still, it is impossible to identify whether the watching target person is sleeping or not.

  On the other hand, as a method of observing the biological information of the human body, the human body is irradiated with microwaves, the reflected wave reflected by the human body is detected, and the state of the human body's breathing and heartbeat is determined based on the phase difference signal between the irradiated wave and the reflected wave. Non-contact detection technology is also being studied. For example, Patent Document 3 uses this technology to acquire more information by measuring respiration and heart rate, and to detect sudden changes in health and apnea syndrome. A body information measuring apparatus that can detect body information more deeply is disclosed. By applying such technology for watching, Patent Document 3 describes that it is useful even when a home caregiver confirms the safety of a care recipient (care recipient) in a separate room at home or in a remote place when going out. Although there is a description, a specific method is not described.

In addition, each of the above prior arts focuses on grasping the situation of the target person, and does not consider the environmental state of the living room. For example, when the room temperature or humidity exceeds a predetermined value, there is a risk of heat stroke even in a living room, and when the room temperature is higher, there is a risk of fire. As described above, even if partial information of the target person who needs to be watched is obtained in the conventional technology, a mechanism for easily determining whether or not the situation requires a comprehensive countermeasure has not yet been realized.
Furthermore, even if some abnormality is detected and notified to the family in the conventional technology, the family who has received the notification cannot easily grasp how much the situation is problematic. Eventually, it may happen that the person who is watching over, such as a family member or helper, cannot confirm the situation correctly without actually visiting the site.

Japanese Patent Laying-Open No. 2015-060238 JP 2013-195374 A Japanese Patent Laid-Open No. 2014-210137

  The present invention has been made in view of the problems in the conventional monitoring system, and the object of the present invention is to comprehensively determine the biological information of the watched person and the environmental state of the living room, and easily monitor the situation. It is to provide a non-contact watching system that can grasp the situation.

  A non-contact watching system according to the present invention made to achieve the above object is a non-contact watching system including a watching device, an information management device and a watcher terminal connected via a network, wherein the watching device is watched over. Installed in each living space at the living base of the person, a biological information acquisition unit that acquires the biological information of the watched person by irradiating microwaves, an environmental information acquisition unit that acquires environmental information of each living space, and an abnormality An information acquisition unit that acquires an image of an installation location when the occurrence of the information, and the information management device manages information for each subject, such as daily biological information and medical history of a watched person to be watched over Living information including at least the biological information and the environmental information is acquired from the management unit and the watching device, and the living information of the watched person is based on the management information for each subject Comprehensively ranked according to the state of determination to abnormal, characterized in that it comprises a total determination unit for transmitting the icon corresponding to the ranks to the watcher terminal.

  The monitoring device includes a parent device and a plurality of child devices, and the child device further includes a communication unit that transmits the biological information and the environment information to the parent device, and the parent device acquires the parent device A living information management unit that manages the living body information and the environment information, and the living body information and the environment information received from the slave unit, and determines whether or not there is an abnormality based on a predetermined determination criterion; and the living information It is preferable to further include an input / output unit that transmits life information including the biological information and the environment information managed by the management unit and the determination result to the information management device.

The information management device receives an image transmission request from the watcher terminal, and acquires the image from the watch device when the life information of a target watcher is in an abnormal state of a predetermined rank or higher. It is preferable to transmit to the watcher terminal.
Preferably, the information management device further includes an MDM management unit that manages an MDM (Mobile Device Management) that deletes personal information stored in the watcher terminal.
It is preferable that the monitoring device further includes an alarm generation unit for notifying the watched person of an abnormality that has occurred in the living room space where the watched person is present or in another living room space.

According to the non-contact watching system according to the present invention, since a sensor capable of grasping biological information and environmental information is installed in each living space of the watched person's living base, the watched person is grasped in what place and in what state. Cheap. In addition, if there is an abnormality in the watched person or living space, the watcher such as a family member or helper is notified with an icon display corresponding to the degree of abnormality, so the watcher needs to respond to the watched person. It can be easily judged.
Furthermore, according to the non-contact watching system according to the present invention, if there is an abnormality at a level that requires immediate action, the watcher can confirm the situation of the watched person with the camera at an early stage. There is also an effect that appropriate measures can be taken.

It is a block diagram showing roughly composition of a non-contact watching system by an embodiment of the present invention. It is a block diagram which shows roughly the structure of the monitoring apparatus by embodiment of this invention. It is the schematic which shows the attachment state to the living room of the monitoring apparatus by embodiment of this invention. It is a flowchart for demonstrating the processing flow of the monitoring apparatus (master) of the non-contact monitoring system by embodiment of this invention. It is a flowchart for demonstrating the processing flow of the information management apparatus of the non-contact watching system by embodiment of this invention.

Next, a specific example of a mode for carrying out the liquid crystal display non-contact watching system according to the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram schematically showing the configuration of a non-contact watching system according to an embodiment of the present invention.
Referring to FIG. 1, the non-contact watching system 1 includes a watching device 10, an information management device 20, and a watcher terminal 30 connected via a network 5.

The watching device 10 is a device that determines whether there is any abnormality while acquiring data on the living situation of a watched person such as an elderly person living alone or a bedridden sick person who needs to be watched in a non-contact manner. It is installed in the person's living base. When an abnormality occurs, information on the abnormality is transmitted to the watcher's terminal via the information management device 20 described later, and the person concerned with the watcher, such as the watcher's family and the helper in charge, quickly knows the occurrence of the trouble. be able to. Although FIG. 1 shows a case where there is a single watching device 10, when there are a plurality of watched persons, a plurality of watched apparatuses 10 are installed for each watched person.
As shown in FIG. 1, the watching device 10 includes a life information management unit 110, a biological information acquisition unit 120, an environment information acquisition unit 130, an image acquisition unit 140, an input / output unit 150, a storage unit 160, and a control unit 170.

  The biological information acquisition unit 120 is an element for acquiring the biological information of the watched person without contact. Here, the biological information refers to information related to biological activities such as breathing, heart rate, and movement of the watched person. In order to acquire such biological information in a non-contact manner, the biological information acquisition unit 120 includes a transmission unit that irradiates microwaves and a reception unit that receives microwaves reflected by the watched person. Since a phase difference is caused by the Doppler effect between the microwave irradiated by the watched person's movement and the received microwave, the operation can be detected. Biological activities that are not conscious of movement such as breathing and heartbeat can be detected from slight movements that occur on the body surface due to breathing and heartbeat. Microwaves are emitted from the transmission unit at an irradiation angle of about 180 °, and biological information within a distance range of about 10 m from the transmission unit can be detected. For this reason, in a general Japanese house, it is possible to watch over the person being watched with one watch device per room.

The biometric information acquisition unit 120 further includes an analysis unit that detects a temporal change in the phase difference associated with transmission / reception of microwaves and extracts a frequency component from the temporal change to obtain a respiration rate and a heart rate. The analysis unit keeps pets such as dogs and cats, and even if they are in the same room as the watcher, the watcher's Respiratory rate and heart rate can be identified and extracted.
The biological information acquisition unit 120 can acquire the biological information of the watched person for 24 hours by continuously irradiating the microwave from the transmission unit.

The environment information acquisition unit 130 acquires environment information of the space where the watching device 10 is installed. Here, environmental information refers to information about living space such as room temperature and humidity. In one embodiment, the environment information acquisition unit 130 includes a temperature sensor and a humidity sensor. In other embodiments, a smoke sensor or a sensor that detects gas leakage may be provided. The temperature sensor may be one using a thermistor, one using a resistance temperature detector, or another type. The humidity sensor may be one using a polymer resistor, one using a polymer capacitor, or another method, but an electric sensor that can be taken out as an electric signal is used.
Although temperature sensors and humidity sensors can continuously measure room temperature and room humidity, in general, these environmental information rarely changes rapidly in a short time, so they are intermittent at predetermined time intervals. Alternatively, the configuration may be such that environmental information is acquired.

The image acquisition unit 140 acquires an image of a place where the watching device 10 is installed. For this reason, the image acquisition unit 140 includes a lens, an image sensor, and a control unit. The living state of the watcher can be roughly grasped from the biological information and the environmental information, but it is difficult to judge whether the watcher's movement is unmovable or unmovable, for example, when the watcher's movement is not detected for a long time. .
In such a case, by confirming the image, it is possible to grasp the more accurate state of the watched person. However, unlike biometric information, the image is a factor that causes the mental distress that the watchee always sees the image. In order to avoid such a privacy problem, the image acquisition unit 140 is locked on the control program so that it does not operate at normal times. When an abnormality of a predetermined level or higher is detected, the lock is released and the image acquisition is performed. Is controlled to be possible.

  The image acquired by the image acquisition unit 140 is acquired from the watcher terminal 30 in response to an image transmission request and transmitted from the input / output unit 150. In one embodiment, an image at the time when an abnormality is detected may be acquired and temporarily stored. Furthermore, images may be acquired and stored at regular time intervals. By doing so, the watcher can compare the time point when the abnormality is detected and the time point when the image transmission request is transmitted, or confirm the change over time up to that point in the image. Here, the image has been described on the premise of a still image, but the image acquired by the image acquisition unit 140 may be a moving image. In the case of a moving image, if the acquisition is started from the time when an abnormality is detected, a continuous progress can be confirmed.

The life information management unit 110 acquires and manages the biological information acquired by the biological information acquisition unit 120 and the environmental information acquired by the environment information acquisition unit 130, and determines whether there is an abnormality according to a preset abnormality determination criterion. To do. When an abnormality is detected by the determination, the life information management unit 110 inputs / outputs life information including the biological information, the environment information, and the determination result when the abnormality is detected, together with the abnormality notification signal for notifying that the abnormality has occurred. The information is transmitted from the unit 150 to the information management apparatus 20.
In addition, when an abnormality is detected by the determination, the life information management unit 110 sends an unlock signal to the image acquisition unit 140 so as to shift to a standby state in which image acquisition is unlocked and image acquisition is possible.

If no abnormality is detected, the acquired biological information and environmental information are determined as normal data and stored in the storage unit 160. Since the capacity of the storage unit 160 is limited, the normal data may be stored so that the passage of time can be understood by converting the spot data at a constant time interval into a numerical value, or a numerical value obtained by averaging interval data at a fixed time interval. You may make it preserve | save as data. In addition, data that has passed for a certain period of time may be overwritten and saved on the latest data, and only the latest fixed time may be always saved, so that an increase in storage capacity may be suppressed.
When no abnormality is detected, the life information management unit 110 transmits the latest life information including biological information and environment information from the input / output unit 150 to the information management device 20 at a set time interval or set time. This is because it is used as a part of the reference data when the information management apparatus 20 described later comprehensively determines abnormality.

The storage unit 160 stores biometric information and environmental information, and stores a determination criterion for determining an abnormality, a set time for transmitting life information to the information management apparatus 20, and the like.
The input / output unit 150 is connected to the network 5 and transmits life information and an abnormality notification signal to the information management apparatus 20 and receives an image transmission request. The connection to the network 5 may be wireless or wired, and is provided with a wired LAN connection terminal and a wireless LAN card so that both can be supported. In addition, a SIM card insertion terminal is provided so that communication is possible without performing Internet connection work when the watcher's living base does not have an Internet connection environment. By inserting the SIM card, it becomes possible to connect to the information management apparatus 20 via the wireless communication network of the mobile phone.
The control unit 170 controls the overall operation of the monitoring apparatus 10 and controls each component to perform the above function.

  When the watched person resides in a nursing home, the main living space is often a single room, and the watch device 10 can be watched by being installed in one place. However, when a watched person lives in an individual living base such as a condominium or a detached house, the living space is often divided into a plurality of rooms such as a living room and a bedroom, and watching in each room is required. In this case, the watching device can be composed of a plurality of elements.

FIG. 2 is a block diagram schematically showing the configuration of the monitoring apparatus according to the embodiment of the present invention, and shows an embodiment constituted by a plurality of elements.
Referring to FIG. 2, the watching device 11 includes one parent device 12 and a plurality of child devices 13. Although FIG. 2 shows an example of three slave units (13-1, 13-2, 13-3), the number of slave units is not limited to this.
The configuration of the parent device 12 is the same as the configuration of the watching device 10 shown in the embodiment of FIG. However, the life information management unit 110 of the parent device 12 receives the biological information transmitted from the child device 13 in addition to the biological information acquired by the biological information acquisition unit 120 of the parent device 12 and the environmental information acquired by the environmental information acquisition unit 130. Information and environmental information are managed together, and the presence / absence of an abnormality is determined according to preset abnormality determination criteria.

Since there is no identification of which slave unit the biometric information and environment information transmitted when there are a plurality of slave units 13, each slave unit is given a unique ID number, and the biometric information and the environment information are transmitted. In such a case, it is transmitted in association with a unique ID number.
Similar to the parent device, the child device 13 includes a biological information acquisition unit 120, an environment information acquisition unit 130, an image acquisition unit 140, a storage unit 160, and a control unit 170. Moreover, the subunit | mobile_unit 13 is provided with the communication part 180 for transmitting the biological information which the own biological information acquisition part 120 acquired, and the environmental information which the environmental information acquisition part 130 acquired to the main | base station 12. FIG. Since the transmission of the information from the slave unit 13 to the master unit 12 is performed using a wireless LAN, the slave unit can be installed at a free position within a wireless reach. When terminals for wired LAN in the house are installed in each room, they may be connected by wired LAN.

  In the embodiment of FIG. 2, the handset 13 does not include an element corresponding to the life information management unit 110. This is because life information management and abnormality determination are performed by the parent device 12, whereby the child device 13 can be reduced in size. In addition, a slave unit installed in a place where privacy is particularly required such as a toilet or a bathroom may be configured without the image acquisition unit. Thus, you may mix the subunit | mobile_unit from which a structure differs with the place where a subunit | mobile_unit is installed. Also, the mounting location and shape may be changed according to the installation location. For example, a slave set installed in the bedroom of a watched person who has been sleeping on the bed may be placed under the bed in order to obtain biological information with high accuracy.

FIG. 3 is a schematic view showing a state in which the watching device according to the embodiment of the present invention is attached to a living room.
The master unit 12 is installed in the bedroom a and continuously acquires the temperature and humidity, which are the environmental information of the bedroom a, and the slave unit 13 is installed in the living room b and continuously acquires the temperature and humidity of the living room. . When the watched person is in the living room, the biological information acquisition unit 120 of the child device 13 acquires the biological information of the watched person. Therefore, the parent device that has received the biological information from the child device is in any state ( Whether breathing rate, heart rate, and presence or absence of motion).
When the watched person is in the bedroom, the handset 13 does not receive the reflected wave that senses the movement, and therefore, the biological information is transmitted to the base unit 12 as a flat signal with no change. On the other hand, since the biometric information acquisition unit 120 of the master unit 12 acquires the biometric information of the watched person, the parent machine 12 analyzes what state the watched person is in the bedroom (respiration rate, heart rate, and presence / absence of motion). be able to.

  Moreover, the monitoring apparatus (10, 11) can set a specific biological information observation area at the time of installation. For example, when the watched person is almost bedridden and spends most of the day on the bed, the biological information observation area is set to be the area c around the bed as shown in the parent device 12 of FIG. be able to. When a biometric information observation area is set, the master unit 12 is abnormal when the watched person leaves the biometric information observation area by setting a criterion for making an abnormality when no breathing or heartbeat is observed in this area. Can be detected as By setting the living body information observation area in this way, it is possible to detect a fallen person from the bed or a heel of the watched person. Since the watching devices (10, 11) include the image acquisition unit 140, the biological information observation area can be easily provided by providing means for displaying a marker indicating the biological information observation area on the image acquired by the image acquisition unit. It can also be set as the structure which can be set.

  The watching devices (10, 11) are not shown in FIGS. 1 and 2, but may include an alarm generating unit that issues an alarm to the watched person with sound, light, or voice. As a result, the monitoring device (10, 11) alerts the operation of the air conditioner or the use of the fan because there is a risk of heat stroke if the temperature or humidity of the living room where the watched person currently exceeds a preset reference value. Can be issued. In addition, when it is detected that the living room space where the watched person is present and a different living room space are abnormally high, it is possible to notify the watched person that there is a risk of fire.

Although the watching devices (10, 11) are not shown in FIGS. 1 and 2, they may include a calling unit including a microphone and a speaker. Thereby, when abnormality occurs, a call can be made to the watched person from the watcher terminal 30. Conversely, it is possible to transmit a support request from the watched person to the watcher terminal 30 as a voice.
Furthermore, the watching devices (10, 11) may include a receiving unit for receiving a radio signal from a portable terminal that issues a support request signal that the watched person wears and carries. The monitoring device focuses on detecting the abnormality of the watcher through the biological information and environmental information and notifying the watcher, but when the watcher himself needs assistance due to a fall, the watcher By detecting that the mobile terminal that issues the support request signal is operated with the intention of the user and notifying the watcher, a more appropriate response can be made.

  Referring to FIG. 1 again, the network 5 is a communication network for the monitoring device 10, the information management device 20, and the watcher terminal 30 to transmit and receive life information and image transmission requests, and is a wide-area communication network such as the Internet. . If the watched person is in a nursing home, the information management device 20 may be installed in the nursing home. In that case, the monitoring device 10 and the information management device 20 are connected by a LAN in the nursing home, and information management is performed. The apparatus 20 and the watcher terminal 30 may be connected via an Internet line. Thus, the network 5 may be configured by connecting different types of communication means.

The information management device 20 acquires life information from the monitoring device 10, determines whether there is a general abnormality with reference to personal information such as the medical history of each watched person, and watchers related to the watched person This is a device for notifying an easy-to-understand icon of the status of the watcher who falls under.
Referring to FIG. 1, the information management apparatus 20 includes an information management unit 210, a comprehensive determination unit 220, an MDM management unit 230, an input / output unit 240, a storage unit 250, and a control unit 260.

The information management unit 210 manages management information for each subject such as daily biological information and medical history of the watched person who is the subject of watching. The management information by subject includes basic information such as the address, name, and age of the watched person, medical history information including the history of the disease that the watched person has developed in the past, and the daily breathing rate and heart rate of the watched person. It includes track record information, abnormality history information including life information when an abnormality is detected, and contact information including a list of watchers who notify the status of the watchee.
In the initial state, the performance information registers the daily respiratory rate and heart rate values included in the application from the watched person or the watcher in advance, but after starting the watch, the information management device 20 is transmitted from the watch device 10. Normal time data is received and stored in time series so that changes with time can be extracted.
Since the information management device 20 handles personal information, the information management unit 210 issues individual IDs to the watched person and the watcher at the time of initial registration of the management information for each target person, and accepts a password for each ID. The separate management information is managed in association with the ID and password.

The comprehensive determination unit 220 acquires life information including at least biometric information and environmental information from the monitoring device 10, and comprehensively determines the life information of the watched person based on the management information for each person managed by the information management unit 210. Rank according to the abnormal state, watch the icon corresponding to the rank and send it to the terminal.
As described above, the monitoring device 10 determines the presence or absence of an abnormality in accordance with a preset abnormality determination criterion, and when an abnormality is detected, the living body when the abnormality is detected together with an abnormality notification signal for notifying that an abnormality has occurred. Living information including information, environmental information, and determination results is transmitted to the information management apparatus 20.

However, for example, even if the respiratory rate exceeds a preset abnormality criterion, it may not be a serious abnormality for a watcher who normally has a high respiratory rate. On the contrary, even if the watched person's heart rate fluctuates, if it is within the abnormality determination standard of the watching device 10, it is transmitted as normal data from the watching device 10, but it is abnormal for the watched person who has heart disease history information. It may happen that it should be determined.
Thus, in judging the situation of the watched person, it becomes possible to judge more accurately by referring to the daily performance information and medical history information of the watched person. The comprehensive determination unit 220 realizes an accurate determination by comprehensively determining an abnormality based on the management information for each person with respect to the life information transmitted from the monitoring device 10.

As a result of comprehensively determining the abnormality, the overall determination unit 220 performs ranking according to the state of the abnormality. For example, in one embodiment, ranking is performed in three levels: a normal level, a level that does not require an emergency but requires confirmation, and an emergency level that requires immediate treatment.
In addition, the comprehensive determination unit 220 extracts icons registered in advance corresponding to the rank classification and transmits the extracted icons to the watcher terminal 30. It is preferable to change the shape and color of the icon so that the received watcher can judge the urgency level at a glance. For example, the normal level is green, the level that does not require emergency but the level that requires confirmation is displayed in yellow, and the level that requires immediate action is displayed in red, so that the watcher can grasp the situation intuitively . The ranking is performed for each of the biometric information and the environment information, and each is displayed with an icon and transmitted to the watcher terminal 30. Thereby, the watcher can easily determine what kind of abnormality has occurred.

The MDM management unit 230 manages software that can remotely operate a mobile device called a mobile device management. If the watcher loses the watcher terminal 30 and personal information may be leaked, the watcher terminal 30 is managed. Delete your personal information.
In FIG. 1, the MDM management unit 230 is shown to be included in the information management apparatus 20, but in another embodiment, a server is connected to the network 5 separately from the information management apparatus 20, and the server is provided with the MDM management unit. May be.

The input / output unit 240 receives life information from the watching device 10 and transmits an icon indicating the status of the watched person to the watcher terminal 30. Also, an image transmission request to be described later is received from the watcher terminal 30, received by the watcher device 10, received from the watcher device 10 corresponding to this, and transmitted to the watcher terminal 30.
The storage unit 250 stores the management information for each subject managed by the information management unit 210, the icon information for each rank, and the like.
The control unit 260 controls the operation of the information management apparatus 20 and manages each component so as to perform the above function.

The watcher terminal 30 displays an icon indicating the status of the watched person from the information management device 20 and notifies the watcher. Although FIG. 1 shows the case where there is one watcher terminal 30, there are often a plurality of watchers such as family members and helpers. In that case, there are a plurality of watcher terminals according to the number of watchers. Moreover, when there are a plurality of watchers, a plurality of configurations are provided.
Referring to FIG. 1, the watcher terminal 30 includes an input / output unit 310, a storage unit 320, a control unit 330, and a display unit 340.

The watcher terminal 30 is embodied by a smartphone, a tablet PC, a notebook PC, or the like. The icon indicating the status of the watched person transmitted from the information management device 20 is displayed on the display unit 340 separately for the biological information and the environmental information.
When the watcher terminal 30 selects an icon with a mouse or a tap, the watcher terminal 30 displays detailed information regarding the icon. For example, when the biometric information is an icon indicating an emergency level that requires urgent treatment, the watcher terminal 30 displays the specific values of the respiratory rate and the heart rate that are the biometric information of the watched person when the icon is selected. . At this time, normal data may be displayed together so that they can be compared.

  When the icon indicates an emergency level that requires immediate treatment, the watcher terminal 30 displays an image transmission request button on the display unit 340. When an image transmission request button is selected by the watcher, an image transmission request signal is transmitted to the information management apparatus 20. When the information management device 20 confirms that the image transmission request has been transmitted from the watcher terminal 30, the target watcher is identified from the management information for each subject, and the current state of the watcher is immediately treated. When it is at a necessary emergency level, the image transmission request is transmitted to the watching device 10 to acquire an image from the watching device 10 and transmitted to the watcher terminal 30. The watcher terminal 30 displays the received image on the display unit 340, whereby the watcher can grasp a more accurate status of the watched person, so that appropriate processing can be quickly performed.

FIG. 4 is a flowchart for explaining the processing flow of the watching device (master unit) of the non-contact watching system according to the embodiment of the present invention.
Referring to FIG. 4, parent device 12 of monitoring device 11 acquires biological information by irradiating microwaves with biological information acquisition unit 120 (step S <b> 100). Next, environmental information including room temperature and humidity is acquired by the environmental information acquisition unit 130 (step S110). The order of obtaining the biological information and the environment information may be reversed, or both pieces of information may be obtained simultaneously.

  The master unit 12 receives the biological information from the slave unit (step S120), and subsequently acquires the environment information (step S130). In this case as well, the order of the biological information and the environmental information received from the child device may be reversed, or the biological information and the environmental information may be received together. If there are a plurality of slave units, information on all slave units is received. At this time, the ID given to each of the slave units is transmitted together with the biometric information and the environment information so that the master unit can identify the data transmitted from which slave unit.

  The base unit 12 manages the biological information and environment information acquired in steps S100 and S110, and the biological information and environment information received in steps S120 and S130 as life information at that time, and stores them in the storage unit 160 (step S140). ). Base unit 12 determines whether or not there is an abnormality in accordance with an abnormality determination criterion set in advance for the life information in step S140 (step S150). When it is determined that there is an abnormality, the base unit 12 enters the life information including the biological information, the environmental information, and the determination result when the abnormality is detected, together with the abnormality notification signal for notifying that the abnormality has occurred, as abnormal data. The information is transmitted from the output unit 150 to the information management apparatus 20 (step S160). Further, the lock for image acquisition is released, and a transition is made to a standby state in which image acquisition is possible (step S170). At this time, unlocking of image acquisition may be performed only for the image acquisition unit of the parent device or the child device installed in the place determined to be abnormal, or for all image acquisition units of the parent device and the child device You may go.

  If it is determined in step S150 that there is no abnormality, it is determined whether it is a set time in which the time for transmitting life information to the information management apparatus 20 is set in advance (step S180). Information is transmitted to the information management apparatus 20 as normal data (step S190), and the process returns to step S100 to repeat the process. If it is determined in step S180 that the set time has not been reached, the process returns to step S100 and the process is repeated.

FIG. 5 is a flowchart for explaining the processing flow of the information management device of the non-contact watching system according to the embodiment of the present invention. Processing for receiving life information from the watching device, making a comprehensive judgment and notifying the watcher Indicates.
Referring to FIG. 5, the information management device 20 receives life information from the monitoring devices (10, 11) (step S200). In addition, when there are a plurality of watchers and there are also a plurality of watch devices, the information management device 20 issues a unique ID to each watch device at the initial registration, and the management information for each target person The ID of the monitoring device is managed in association with each other, and the monitoring device can identify the information from which monitoring device by transmitting together with the unique ID when transmitting the life information.

  Based on the ID transmitted from the watching device (10, 11), the information management device 20 extracts management information for each subject associated with this ID (step S210). The information management device 20 comprehensively determines the life information transmitted from the monitoring devices (10, 11) based on the extracted management information by subject, and what is the current state of the watched person? Is determined (step S220). The state is specified by ranking according to a pre-defined ranking. When the ranking is completed, the information management apparatus 20 extracts an icon corresponding to the corresponding rank from the icon correspondence table set and stored for each rank in advance (step S230).

  Next, the information management device 20 determines whether or not the determined rank is abnormal (step S240), and if it is a rank corresponding to the presence of abnormality, the monitor is identified from the management information for each target person, and the watcher of the watcher An icon is transmitted to the terminal 30 (step S250). At this time, the life information determined to be abnormal is transmitted together with the icon. Thereby, it can comprise so that a watcher can select the icon displayed on the watcher terminal 30 and can confirm concrete life information.

  When it is determined in step S240 that there is no abnormality, the information management apparatus 20 updates the normal data managed by the information management unit 210 assuming that the acquired life information is normal data (step S260). Since the normal data is not urgent, the icon and life information to be transmitted to the watcher terminal 30 are transmitted at a preset time. Therefore, the information management apparatus 20 determines whether or not it is the set time in step S270, and transmits the icon and life information to the watcher terminal 30 in step S280 if it is the set time. If the set time has not been reached in step S270, reception of life information from the watching device is awaited.

  As mentioned above, although embodiment of this invention was described referring drawings, this invention is not limited to the above-mentioned embodiment, It can change variously within the range which does not deviate from the technical scope of this invention. Is possible.
