Description

Detailed description of the invention

The present invention relates to a technical field for automatically confirming the safety of a single resident or an elderly person without installing any special operation or monitoring device, and in particular, an earlier opportunity for an abnormal condition or lonely death of a single resident. It relates to a safety confirmation system and method for detecting.

The number of elderly single residents is increasing with the aging of the population, and it is social to detect, treat, and respond to abnormal situations in daily life (illness, incident, accident, death, etc.) due to single life at an early stage. It is becoming important as an issue. It is necessary to detect the occurrence of an abnormal situation or its fear or possibility and confirm the safety of the single resident, not only to worry about the relatives and related persons of the single resident, but also to take early measures such as illness. , Avoid fatal situations by early detection of incidents and accidents, avoid lonely deaths as much as possible for single-resident resident lenders, and improve housing value by early response even in the unlikely event of death It is also needed to maintain.

Various techniques for confirming the safety of single residents and the elderly have been disclosed conventionally. For example, Patent Document 1 discloses a method of attaching a sensor to water services to detect lonely death at an early stage depending on the state of use of water services, and Patent Document 2 attaches a sensor to a door knob or the like used in daily life to connect a telephone line. A method for confirming the safety status at a safety confirmation center or the like is disclosed through the system.

Further, in Patent Document 3, the present inventor uses a vital sensor attached to an indoor lighting device or the like to detect the heartbeat, respiration, and body movement of a resident by microwaves from a distant place to confirm the safety. We are proposing a device. In addition, many methods and devices for confirming safety using a portable device have been proposed. For example, Patent Document 4 describes a method in which a safety confirmation message is transmitted from a monitoring center to a mobile terminal of a target person, and the target person taps the mobile terminal to confirm the safety. Discloses a method and a device for transmitting physical information of a subject to a portable device which is a master device by a slave unit incorporating a body sensor, and always relating the safety state of the subject.

Japanese Unexamined Patent Publication No. 2019-28554 Japanese Unexamined Patent Publication No. 2001-357475 W02018-074576 Gazette JP-A-2018-163549 Utility Model Registration No. 3131971

In the techniques disclosed in Patent Document 1 and Patent Document 2 described above, it is necessary to attach a sensor to a water supply or a doorknob that is used daily, and to install a device that sends and receives signals between the sensor and a communication device. Installation work and equipment development will be required to construct these systems.

Further, in the safety confirmation technique of Patent Document 3, although the vital information of the subject can be surely determined because the vital information of the subject can be determined, the device and system construction are complicated and the system is maintained. Combined with management costs and communication costs, the system will be expensive.

Further, in Patent Document 4, it is possible to confirm the safety at low cost by using a portable device, but since it is a method of notifying the safety by the user operating the mobile terminal in response to the inquiry of the safety confirmation, it depends on the elderly. Since the operation is unfamiliar, it may not be possible to accurately contact the safety. Similarly, in Patent Document 5, as a technique for confirming the safety with a mobile terminal, the mobile terminal is used as a master unit, a vital sensor is installed in the slave unit, and vitals such as body heartbeat, heart movement, breathing, and body movement acquired by the slave unit are obtained. In order to send information to the mobile terminal that is the master unit, send such information to the monitoring center, and confirm the safety, it is necessary to install and hold not only the master unit of the mobile terminal but also the slave unit that is a vital sensor. ..

With such conventional technology, it is inconvenient and complicated for the elderly who are not good at operation and the cost and maintenance cost are relatively high to confirm the safety of a single resident, especially an elderly person living alone. It was not convenient. The present invention has been made in view of such problems, and it is possible to solve these problems, (1) simplify the operation of the person to be watched (monitored person) as much as possible, and confirm the safety without operating as much as possible. The purpose is to provide a system and method that enables safety confirmation without the need for special device development or installation work such as sensor installation, and (3) safety confirmation at extremely low cost.

In order to solve such a problem, the present invention has the following features. In a monitoring system in which the monitored person's mobile communication terminal possessed by the monitored person and the monitored person's communication terminal possessed by the monitor are connected via a cloud network, the monitored person's mobile communication terminal is a body motion detection sensor. The body movement pattern including the body movement detection period and the non-detection period of the monitored person acquired by the body movement detection sensor, which has a transmission means, is constantly or periodically transmitted to the cloud server of the cloud network, and is described as described above. The observer communication terminal has a receiving means for acquiring the body movement pattern of the monitored person from the cloud server, and is monitored by using the body movement pattern of the monitored person grasped by the receiving means of the monitored person communication terminal. It is characterized by confirming the safety of the person.

Further, in the monitoring system according to the present invention, the monitored person's mobile communication terminal further has a timer means, and the body movement pattern is transmitted to the cloud server of the cloud network at intervals set by the timer means. It is characterized by being automatically transmitted.

Further, in the monitoring system according to the present invention, the body motion detection sensor is a gyro sensor, a compass sensor, an acceleration sensor, a GPS sensor, or a combination thereof.

Further, in the monitoring system of the present invention, when the non-detection period exceeds a set predetermined time, an alert signal is transmitted to the monitored person.

Further, in the monitoring system of the present invention, the body movement pattern of the monitored person is stored on the cloud server, and the non-detection period exceeding a predetermined time in the storage means is steady every day, one week, or one month. When it is detected as the target non-detection period, a message indicating that the constant non-detection period is in progress is transmitted to the observer and / or the destination of the monitored person together with the alert signal during the stationary non-detection period. It is characterized by that.

Further, in the safety confirmation method according to the present invention, a step of detecting a body movement pattern including a detection period and a non-detection period of the monitored person by a body movement detection sensor in the monitored person's mobile communication terminal device, and the above-mentioned body movement. A step of transmitting the pattern to the cloud server via the cloud network, a step of storing the transmitted body movement pattern of the monitored person in the cloud server, and a continuous integration of the stored non-detection period of the body movement pattern. When it is detected that the time has passed a predetermined reference value or more, it is characterized by including a step of transmitting an alert signal to the observer and the monitored person.

Further, in the safety confirmation method according to the present invention, the body movement pattern is memorized, and the non-detection period exceeding the stored predetermined time is detected as a steady non-detection period of one day, one week, or every month. In this case, it is characterized by including a step in which a message indicating that the stationary non-detection period is in progress is transmitted together with the alert signal to the observer's destination during the stationary non-detection period.

In the safety confirmation system and method of the present invention, a single resident or an elderly person living alone owns a mobile communication terminal, does not perform any special operation, and installs a monitoring device, a sensor, or the like. No construction work is required, and the body movement pattern of the monitored person is periodically and automatically transmitted to the monitor, and the safety of a single resident or the elderly living alone can be confirmed at low cost.

It is explanatory drawing of the body movement pattern acquired by this invention. It is a flow chart which shows the flow of the safety confirmation by the monitoring system which concerns on embodiment of this invention. It is explanatory drawing which shows the hardware configuration of the standard mobile terminal apparatus.

Mobile communication terminal devices (smartphones, etc.) have become extremely convenient and indispensable in daily life because their functions have increased from conversation and e-mail to many functions. In particular, in addition to the conventional functions, all functions such as Internet, breaking news, map / navigation, camera, video, money payment, healthcare, various measurements, and security are becoming possible in a miniaturized mobile terminal. .. For this reason, various sensors are incorporated as de facto in the mobile communication terminal device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description, all the drawings described in the examples are drawn as schematic schematic views for the purpose of explaining the present invention, and the means and configurations provided inevitably and naturally are omitted. .. Also, the dimensions and shape are not exact. Therefore, the dimensions, materials, shapes, relative arrangements, etc. of the components are not intended to limit the technical scope of the invention to those alone unless otherwise specified.

FIG. 4 is an explanatory diagram of the hardware configuration of the standard mobile communication terminal device 50. The main hardware components are a transmitter / receiver (communication section) 51 including an antenna, a modem section 52, an application processor (AP) 53, a D-RAM memory 54, a flash memory 55, a display 56, a camera / video 57, and an audio section. In addition to the basic configuration of 58, speaker / microphone 59, interface (I / O) unit 60, etc., various sensors including sensor unit 61 are equipped to achieve many additional functions. In addition, peripheral devices 62 are provided with functions such as GPS, navigation, various measurements (clock, timer, stopwatch, altitude, barometric pressure, etc.), various communications (W-LAN, Bluetooth, etc.), and power supply unit 63 as almost default. ing.

In recent years, with the progress of MEMS (Micro Electro Mechanical System) technology, the functions of smartphones have been expanded, and additional functions such as GSP, map search, navigation, games, pedestrian meters, altimeters, barometers, compasses, accelerometers, and up and down smartphones have been expanded. -A motion sensor unit 61 as a hardware device compatible with a vertical / horizontal display switching function is incorporated as a standard. In particular, gyro sensors, geomagnetic compass sensors, acceleration sensors, GPS sensors, etc. are motion sensors that are indispensable for achieving these functions, and these sensors should be used to detect the body movements and behaviors of smartphone users with high sensitivity. Can be done. Therefore, these sensors provided in the motion sensor unit 61 automatically determine the user's body movements such as up / down, left / right movement, rotational movement, movement speed, movement direction, movement location, etc. just by being owned by the user. Can be obtained in.

Such various sensors of the motion sensor unit 61 are used to achieve functions such as navigation, games, and compass in cooperation with a cloud server via a communication network, and operate software applications stored on the cloud side. This makes it possible to acquire and store various sensor outputs.

In the present invention, the safety confirmation application software based on the present invention is incorporated in the mobile communication terminal device (smartphone) owned by the monitored person who is a single resident or an elderly person living alone, and various default motion sensor units are incorporated. The body movement of the monitored person is detected using any of the motion sensors of 61, and the monitoring person periodically and automatically acquires the body movement pattern to constantly confirm the safety state of the monitored person.

A specific configuration of the system for monitoring the safety of the monitored person according to the present embodiment will be described with reference to FIG. FIG. 1 is an explanatory diagram showing a main configuration of a safety monitoring system according to an embodiment of the present invention. The mobile communication terminal device (monitored terminal) 1 owned by the monitored person and the communication terminal device (monitored terminal) 2 owned by the monitor are connected to the cloud server 3 via a network. As the monitored person terminal 1, a smartphone having a configuration as shown in FIG. 4 can be used. The monitored person terminal 1 has a transmission / reception unit 11 with a communication network, a body motion detection sensor 12, and a display unit 13, all of which are provided in a standard smartphone. The body motion detection sensor 12 used in the present invention is the sensor of the sensor unit 61 in FIG. 4, and any one or a combination of the above-mentioned gyro sensor, geomagnetic compass sensor, acceleration sensor, and GPS sensor is used for body motion detection. ..

When a gyro sensor is used as the body motion detection sensor 12, for example, an example of the gyro sensor is to detect the movement of the X-axis, the Y-axis, and the Z-axis in the three-dimensional direction, and has a drive circuit for vibrating the MEMS element unit. The capacitance signal obtained from each of the X-axis, Y-axis, and Z-axis collior forces is converted into a voltage and output. The detection circuit block captures the change in capacitance (charge) generated by the Coriolis force and converts it into a voltage value to provide an output signal proportional to the change in distance between the electrodes. Therefore, when the monitored person moves up and down or left and right, a voltage signal is generated from the drive circuit and can be detected as a sensor output. In the present invention, it is important to detect the presence or absence of body movement, and information such as up / down, left / right directions, moving speed, and moving distance is not particularly required.

The output of the body motion detection sensor 12 differs depending on the type of the detection sensor and the OS (Operating System) of the terminal, but is automatically transmitted from the sequential transmission / reception unit 11 to the cloud server 3 via the communication network at all times or at any time, and is automatically transmitted to the cloud server. It is memorized and accumulated in. Any detection sensor or OS may be used to detect the presence or absence of body movement, which is the object of the present invention.

When the monitored person holds the monitored person terminal 1 and an output is generated from the body motion detection sensor 12, the output is sequentially transmitted to the cloud server 3 and held as a body motion detection signal for a predetermined time from the time of body motion detection. , The detection period (referred to as the on period). If the next body motion signal is detected within such a holding time, the holding period will continue as a detection period (on period) from that point. When the on signal is interrupted, the non-detection period (referred to as the off period) in which body movement is not detected is counted. The body motion detection signal may be uploaded to the cloud server 3 as it is at all times, but it is uploaded to the cloud server 3 at a predetermined interval (for example, every 15 minutes) by a timer means in the monitored terminal 1 and the predetermined interval. If body movement is detected within the interval, a method of transmitting to the cloud server 3 as an on period may be used. Such an on period and an off period can be grasped as a body movement pattern in chronological order by repeating simple on / off as shown in FIG. In the present invention, the on-period in which the body movement and heart movement of the monitored person is detected is referred to as a body movement detection period, and the off period in which the on-period is interrupted and the body movement signal is not detected is referred to as a body movement non-detection period. The pattern consists of a detection period and a non-detection period regarding the body movement of the monitored person.

The body motion information transmitted (uploaded) to and stored in the cloud server 3 from the transmission / reception unit 11 of the monitored terminal 1 is transmitted on the monitor terminal 2 by the observer terminal 2 accessing the cloud server 3. Can be grasped. The observer terminal 2 can be owned or accessed by a plurality of observers such as relatives and related persons of the monitored person (single resident, elderly person living alone, etc.), a security company, and a renter. The observer terminal 2 receives (downloads) the body movement information transmitted / stored in the cloud server 3 at all times or at any time by the transmission / reception unit 21, and displays the body movement pattern on the display unit 22. The display on the display unit 22 displays the body movement detection status (for example, "I'm fine") during the on period as the body movement pattern at the time of monitoring, and the body movement non-detection status (for example, "○○ minute body") during the off period. It is motion non-detection "), and if necessary, the record of past body movement patterns can be displayed. The safety monitoring by the access for detecting the body movement pattern from the monitor terminal 2 to the cloud server 3 may be performed either constantly or periodically according to the needs of the monitor.

The display method of the body movement pattern on the monitor terminal 2 is performed by any method such as video display of the body movement pattern, short message, e-mail, voice, etc. on the display unit 22 of the monitor terminal 2 of the monitor set in advance. Be told. The monitor terminal 2 may be any terminal device such as a smartphone, tablet, or PC as long as it can receive (download) the body movement pattern signal or message of the cloud server 3 and display it. Since these series of operations are basically controlled on the cloud side by a software program using the functions of the storage means 31, timer means 32, arithmetic control means 33, etc. possessed by the cloud server 3, the monitored person terminal 1 Can be achieved by simply uploading the body movement pattern of the monitored person acquired by the body movement sensor 12.

The on signal (body motion detection signal) is maintained for a certain period of time, the off signal (body motion non-detection signal) starts counting from the point of interruption, and this off signal period (body motion non-detection period) is for a certain period of time (for example, 12). If it continues for more than a certain amount of time, the first alert signal (alert 1 signal) is transmitted to the monitored person terminal 1. The timing of the alert 1 signal and the transmission command are transmitted to the monitored person terminal 1 using the push communication function by setting a program on the cloud server side. This alert 1 signal indicates that the body movement signal has not been detected for a certain period of time (for example, 12 hours), and a message requesting the monitored person to confirm the abnormality or some kind of reply (for example, "non-movement"). It has been detected for 12 hours or more, but how are you? Please hold your smartphone. ") In the present invention, the alert signal is a warning signal for alerting the monitored person and / or the observer, and this alert 1 signal is automatically transmitted by a program set in advance on the cloud server 3 side. A message is displayed on the display unit 13 of the monitored person terminal 1 owned by the monitored person, and a voice alert, a blinking light, or the like is contacted. Further, this alert 1 signal is simultaneously transmitted from the cloud server 3 side to the display unit 22 of the monitor terminal 2.

If the monitored person who received the alert 1 signal has no particular abnormality and simply does not have the monitored person terminal 1 (smartphone), the monitored person simply holds the smartphone and the body motion sensor reappears. It operates, the on state (body movement detection state) is secured, it reacts, and it replies.

However, if there is no response from the monitored person to the alert 1 signal, it means that the monitored person's body movement has not been detected by the smartphone for a predetermined time (for example, 12 hours) or more. It is conceivable that some abnormal situation has occurred in the monitored person, or that the smartphone is not possessed. At this point, the observer may send a message or call to the monitored person from the input unit 23 of the monitor terminal 2 according to the situation of the monitored person, or send a watcher to the monitored person in consideration of the necessity or the possibility of abnormality. You may take measures to confirm the status directly by means such as dispatching.

Further, if there is no reaction to the alert 1 signal, a second alert signal (alert 2 signal) may be transmitted after a further predetermined time (for example, 24 hours). In this case, for the monitored person, the alert 2 signal is sent to the monitored person terminal 1 by a message, voice, lighting, etc. by the push communication function in the same way as the alert 1 signal is transmitted by the setting programmed on the cloud server 3 side. To do. In addition, an alert 2 signal is also transmitted from the cloud server 3 side to the monitor terminal 2 to the monitor.

If there is no particular abnormality in the monitored person due to the alert 2 signal and the monitored person simply does not have the monitored person terminal 1 (smartphone), the monitored person simply holds the smartphone and the body motion sensor operates again. The on state (body movement detection state) is secured, and it responds and replies. However, if no response is obtained from the monitored person even with the alert 2 signal, it means that the body movement signal has not been detected for a further predetermined time (for example, 24 hours) or more, and the observer. Since it is necessary to confirm the situation more reliably than in the case of the alert 1 signal, you can directly confirm the status of the monitored person by telephone or message, or visit directly to check the status of the monitored person, or watch over the administrator. Check the status by means such as dispatching personnel. The repetition interval and the number of times of such an alert signal can be changed by setting whether it is once or twice or more according to the situation and the environment.

The body movement information transmission of the monitored person according to the present invention is constantly or at any time, periodically and automatically transmitted to the monitor, but the interval can be changed by setting. FIG. 2 shows an example of time-series transition of the on-signal period (body motion detection period) and the off-signal period (stationary period) acquired by the body motion detection sensor 12 per day. In FIG. 2, T1, T2, T3, and T4 are examples of the off period, and this time is an abnormal state in which the smartphone is not possessed by the monitored person, or even if it is possessed, no body movement occurs. Is it? During this off period, the monitored person may be in bed or unable to operate the smartphone due to bedtime, charging, running out of battery, forgetting to carry, illness, or the like.

If the monitored person does not have the smartphone and leaves it unattended, or if it is installed in a charger and does not carry it, the monitored person can react by simply holding the smartphone if it is nearby. Also, if you forget to carry it and go out, you will be able to react in some way when you come home from the outing. However, the most problematic problem in the off period is at bedtime when the off period continues for a long time (for example, 6 hours or more), or when the smartphone is not carried or cannot be carried for a long time. At bedtime, it is not necessary to periodically acquire body motion information (for example, every 60 minutes) and transmit body motion information during that period, and alert signals and the like are monitored during that period. Since the monitored person cannot respond even if the message is sent to the person, the time point at which the alert signal is transmitted is shifted, and the body movement information is acquired (transmitted) and the alert signal is transmitted during the time period when the monitored person can respond. Is desirable. Therefore, in the present invention, a stationary non-detection period, which is estimated to always have an off period every day, every week, or every month for a long period of time, is set as an exclusion condition by learning the body movement pattern of the monitored person.

As for the exclusion condition of the constant non-detection period, which is the long non-carrying time of the smartphone such as the bedtime by the monitored person, the exclusion time can be set by the manual input unit 23 of the monitor terminal 2, but it is daily. By continuously acquiring and learning the routine of the body movement pattern of, it is possible to set it almost automatically in the cloud server 3 by the operation from the monitor terminal 2. In the monitored person terminal 1 according to the present invention, the output signal of the body motion signal is always stored in the cloud server 3, and the average bedtime and length in routine units of one day, one week, and in some cases one month. Estimate the smartphone non-carrying time zone over time. This daily, weekly, or monthly body movement routine is pattern-accumulated, and is constantly accumulated and learned.

If the nap time, outing time, consultation time, bathing time, etc. over a predetermined time set in advance are the body movement routines of the person to be monitored who do not carry a smartphone, these are accumulated and this period is excluded. , Exclusion condition Set the correspondence during the period. For example, during the exclusion condition period, (1) the body movement information is not transmitted to the monitor terminal 2, but is transmitted with the exclusion condition (for example, sleeping, going out, etc.), and (2) the alert signal is transmitted. Even if it is necessary, the alert is not sent, and it is set to be sent before or after the start or end of the exclusion condition period, or a condition message so that the monitored person responds after the end of the exclusion condition period (sleeping, etc.). Send an alert with. By doing so, it is possible to confirm the safety more efficiently and conveniently. However, during this exclusion condition period, there is a possibility that an abnormal situation has occurred in the monitored person even during the exclusion condition period (steady non-detection period) such as at bedtime, so it is natural to calculate the off period. These bedtime are also accumulated as an off period (non-detection period). In addition, the time setting for how many hours or more this exclusion condition should be set can be arbitrarily set in consideration of the behavior pattern and lifestyle of the monitored person.

In this exclusion condition setting, the estimated time is manually set or changed by the input unit 23 of the monitor terminal 2 when the mobile communication terminal is not carried for a long period of time (for example, 6 hours or more) at the beginning of use. However, the off period (steady non-detection period) in the routine information is set more accurately by accumulating and learning while normally being stored in the cloud server 2 and automatically acquiring the body movement information. .. The physical activity routine information of the monitored person based on such exclusion condition setting shows the living condition of the monitored person, and it is necessary for the family / related persons, managers, and housing lenders who are the observers to watch over. It will be extremely useful information, so it is desirable to be able to provide it to the observer as well.

FIG. 3 is a flowchart showing the main flow of the safety confirmation method in the terminal of the monitored person according to the present invention. When the monitored person turns on the communication mobile terminal and the safety confirmation application, the safety confirmation monitoring starts. Whenever the terminal is in operation, the body motion signal of the monitored person is acquired by a motion sensor such as a gyro sensor and is constantly or periodically transmitted (uploaded) to the cloud server 3 (step 1; abbreviated as S1). The same applies below). The body movement signal uploaded to the cloud server 3 determines the presence or absence of body movement (S2). If body movement is detected (S2, Yes), a message with body movement (for example, "energetic message") is automatically sent to the observer (S4), and the system returns to the start and continues monitoring. If no body movement is detected during the period (S2, No), it is determined whether or not a predetermined time (for example, 12 hours) for transmitting the first alert has elapsed (S4). If the first alert set time has not passed (S4, No), a message to that effect (for example, "No body movement detection for XX minutes") is sent to the observer (S5), and the system returns to the start for monitoring. To continue. In this case, the time without body movement detection is continuously accumulated unless body movement is detected.

If the state in which the body motion signal is not detected continues even after a predetermined time (for example, 12 hours or more) has elapsed (S4, Yes), it is determined whether or not the exclusion condition (steady non-detection period) is met. Proceed to step (S6). This exclusion condition may be manually input as described above, but the presence or absence of the body motion signal detected in S1 is stored by the storage means together with the elapsed time (S7), and the body motion signal is constantly accumulated and learned. The body movement routine for one day, one week, and one month is analyzed (S8), and the exclusion conditions are set / updated (S9), which are used as the criteria for determining whether the exclusion conditions are applicable or not. Therefore, the criteria for this exclusion condition are constantly updated due to changes in the body movement routine.

If the exclusion condition (steady non-detection period) is met in step S6 (S6, Yes), a conditional message is sent to the observer (for example, "○○ no body movement detection, exclusion condition: sleeping", etc.) Is transmitted (S10), and the system returns to the start to continue monitoring. In this case as well, the time without body motion detection is continuously accumulated. If the exclusion condition is not met in step S6 (S6, No), the body movement of the monitored person is not detected for more than the reference time (for example, 12 hours) for sending the first alert, and the exclusion condition is also met. Will not. This means that an abnormal situation has occurred in the monitored person, or that the monitored person continues to leave the terminal unattended. Therefore, the terminal automatically sends a first alert signal (alert 1 signal) to the monitored person and the observer (for example, "There is no body movement detection for 12 hours or more, how are you? Please hold your smartphone." ") Or by voice, buzzer, blinking light, etc. (S11). The message of alert 1 is a status inquiry to the monitored person, and requests some kind of reply / reaction (S12).

On the mobile communication terminal side of the monitored person, it is determined whether or not there is a reaction or a reply message from the monitored person (S13). When the monitored person simply holds his / her own terminal again in response to the first alert, the body movement is detected again and it is determined that there is a reaction from the monitored person (S13, Yes), and the system returns to the start and continues monitoring. In this case, the accumulation during the off period is reset. In response to the first alert, the monitored person may be set to automatically send a message (for example, "I'm fine") without any abnormality instead of holding the terminal again (S14).

If there is no response to the first alert and no reply message is received (S13, No), the accumulation of the off period is further continued. Next, it is determined whether or not this off-period state has elapsed the set time (for example, 24 hours) of the second alert (S15). If the second alert setting time has not passed (S15, No), a monitoring continuation message (for example, "○○ no body movement detection, monitoring is continuing") is sent to the observer (S16), and the start is started. Return and continue monitoring. In this case, the accumulation during the off period is not reset and continues. If no body movement continues even after the second alert set time has elapsed and the second alert set time (for example, 24 hours) has passed (S15, Yes), the terminal automatically performs the second alert signal (alert 2). A signal) is sent by a message (for example, "There is no body movement detection for 24 hours or more, is there any abnormality? Please hold your smartphone immediately") or by voice, buzzer, blinking light, etc. (S17). Unlike the alert 1 signal, the alert 2 signal message is a state inquiry that draws the attention of the monitored person, and is a transmission that urgently requests some kind of reply / reaction (S18).

Whether or not there is a response to the emergency status inquiry to the monitored person by the alert 2 signal is determined (S19). When the monitored person leaves the terminal unattended, the body movement is detected again just by holding the terminal again as in the response to the alert 1 message, and it is determined that there is a reaction from the monitored person. (S19, Yes), return to the start and continue monitoring. In this case, the accumulation during the off period is reset. Further, in response to the alert 2 signal, the monitored person may be set to automatically send a message (for example, "I'm fine") without any abnormality instead of holding the terminal again (S16).

However, if there is no response from the monitored person to the alert 2 signal and no reply message is received (S19, No), the monitored person may be in a more serious state, and the monitored person may be in a more serious state. An abnormal signal is transmitted (S21), and the observer who receives the abnormal signal directly confirms the safety of a single resident or an elderly person living alone by notifying the manager, landlord, or related persons or dispatching a person in charge. (S22).

Each step of the above-mentioned flow is a process by exchanging between the monitored person terminal, the watcher terminal, and the cloud server, and the first body motion signal acquisition / transmission step (S1) is owned by the monitored person. It is processed by the monitored terminal, but the other steps are mainly executed as software processing on the cloud server side. Therefore, the burden on the monitored person terminal and the monitored person terminal is reduced, and the software can be changed in a centralized manner according to the situation for confirming the safety, which is excellent in terms of management convenience.

In the above-described embodiment, each step processing of the safety confirmation method in the present invention has been mainly described as software processing on the cloud side, but these processing steps are incorporated into the monitored person terminal 1 and the monitoring person terminal 2 side and executed. Or you may share the execution with each other. Further, in the description of the embodiment, a smartphone, which is the most versatile mobile communication terminal as a monitored person terminal, is taken into consideration, but it does not necessarily have to be a smartphone. The present invention can be implemented by configuring an extremely miniaturized monitored person terminal by using at least a body motion detection sensor, a transmission / reception unit, and a buzzer or the like as a substitute for the display unit.

The safety confirmation step based on the above flow can be achieved by downloading the safety confirmation application software embedded in the cloud to a commercially available monitored person terminal 1 or monitored person terminal 2, and is monitored. If a person holds the monitored person's terminal device that has downloaded these software, the person to be watched over, such as a single resident or an elderly person living alone, and the relatives, related persons, caretakers, and residences of those resident. An observer such as a lender can automatically and regularly confirm the safety without any special operation. This is extremely convenient especially for elderly people who have difficulty in operating mobile terminal devices, and since no special monitoring equipment or equipment work is required for landlords and lenders, it is possible to confirm the safety of residents at low cost. It will be possible.

The present invention has been described as an example of application to a single resident or an elderly person living alone, but the present invention is not limited to this, and can be applied to various indoor and outdoor safety confirmations of children and families within the scope of the gist of the invention. It is possible and has high industrial applicability.
