Description

  The present invention relates to an object information detection apparatus that detects the state of an object, and more particularly to an object information detection apparatus having an illumination function.

Nowadays, a built-in lamp with a built-in biological information detection system that detects an existence of a human body and biological information with a microwave sensor and transmits an alarm signal by simply replacing it with an incandescent lamp bulb as a lighting fixture is introduced.
As one of communication means for transmitting the alarm signal, communication means using power line carrier communication (PLC) is cited (for example, see Patent Document 1 below).

However, such an illumination module with a sensor is easy to install and the like, but there are not a few problems that occur depending on the installation location.
In places where it is easy to be exposed to steam, such as in a bathroom or kitchen, or where the temperature difference is likely to fluctuate, dew condensation occurs when the surface of the sensor-equipped lighting module is turned off (when the surface temperature decreases).
For example, if condensation forms on the surface of the microwave sensor and water droplets are generated, the flow may cause erroneous detection.

In addition, the method of performing various determinations using only the information detected by the microwave sensor involves a relatively difficult process for accurately separating and detecting information of a plurality of test objects, even if a single test object is used. Even so, the accuracy may be significantly inferior depending on the event to be led.
For example, although the presence or absence of movement can be accurately detected, it is relatively difficult to accurately detect the amount or degree of movement or the tendency of movement.
Therefore, there is a problem that the above-described conventional technique requires higher accuracy than that for accurately separating and detecting, for example, brain diseases or heart diseases, injuries, self-injurious behavior, or presence / absence of room.

In addition, since the above conventional method is based on the lighting function that is one of the elements that form the living environment, it is not allowed to neglect the lighting function with the function as a sensor-equipped lighting module. In order to maintain the lighting function, there is also a problem that collection information, analysis items, and transmission information are limited.
For example, a lighting device, which is a means for improving the living environment by brightening indoors and outdoors (life lighting means), has a different purpose of use from a lighting device for photographing to collect image information more clearly. It is not always easy to mount the image sensor integrally and achieve both the illumination function and the image capturing function.

  Even in the collection and management of detected information, an illumination module with multiple sensors can be used more easily to manage the sensor output collection timing and the information obtained from it as the information to be processed increases. It is necessary to equip a large-scale hardware resource, and there is a problem that control is likely to be complicated.

The present invention has been made in view of the above circumstances, and includes a base portion connected to a lighting base, and is intended for convenience of information collection, information analysis, and information transmission, and is used in accordance with the actual situation of the user. It is an object of the present invention to provide an object information detection apparatus that can realize the above system using image information.

  Further, in the former case, a power supply unit that periodically varies the luminance of the LED light emitter during lighting, and a control unit that operates the second sensor unit asynchronously with the luminance cycle of the LED light emitter or the LED A configuration may be provided that includes a control unit that operates the second sensor unit by randomly selecting the luminance of the light emitter, and an information selection unit that discards an image for which effective information sufficient to guide the event is not obtained, In the latter case, a power supply unit that periodically varies the luminance of the LED light emitter during lighting, and a control unit that operates the second sensor unit asynchronously with the luminance cycle of the LED light emitter or the LED light emitter It is possible to provide a control unit that operates the second sensor unit by randomly selecting the brightness and an information selection unit that discards an image for which effective information sufficient to guide the abnormality cannot be obtained.

  Condensation prevention means for controlling the brightness or blinking of the LED light emitter so that the surface of the first sensor unit or the lens of the second sensor unit or the temperature in the vicinity thereof does not fall below the saturated water vapor temperature (condensation prevention process). The communication unit may include a power line carrier communication unit, a communication unit using WiFi or Bluetooth (registered trademark), and the like.

According to the object information detection apparatus of the present invention, the microwave sensor, the imaging device, and the illumination are integrated, and the control unit that adjusts the operation timing of the second sensor unit is provided, thereby eliminating the influence of the light on the image. In addition, not only exercise data but also image data can be used for various purposes as effective information.
For example, a microwave sensor can detect motion data such as heartbeat, respiration or body movement regardless of whether it is a bright place or a dark place, and the image sensor can detect the state / situation of the test object. Thus, depending on the analysis process or the evaluation process, it is possible to detect a plurality of test objects separately.

In addition, the object information detection apparatus according to the present invention can be used alone as an object information detection system, but can be connected to an external organization such as a nurse call system or an emergency call system in conjunction with a router. , You can contact the specified destination via a communication line.
In addition, since the initial setting and the change setting can be remotely performed using the communication line, the burden on the user can be reduced.
In particular, if a configuration is employed in which data is transmitted by PLC or wirelessly, the installation work of the device can be completed by simply attaching it to the lighting base like a light bulb without any wiring work, and it becomes easy to change specifications and add more. .

  Furthermore, the object information detection apparatus according to the present invention includes a power supply unit that periodically varies the luminance of the LED light emitter during lighting, and a control unit that operates the second sensor unit asynchronously with the luminance cycle of the LED light emitter. Alternatively, a configuration is provided that includes a control unit that operates the second sensor unit by randomly selecting the luminance of the LED light emitter, and an information selection unit that discards an image for which effective information sufficient to introduce the event or abnormality cannot be obtained. Therefore, it can be used for various purposes by changing the software without changing the hardware configuration, etc., and the specification change and the function addition are relatively easy.

  The object information detection apparatus according to the present invention controls the brightness or blinking of the LED light emitter so that the surface of the first sensor unit, the lens of the second sensor unit, or the temperature in the vicinity thereof does not fall below the saturated water vapor temperature. By adopting the configuration including the dew condensation prevention means, it is possible to eliminate the situation where the installation location is restricted to a place where there is no condensation, such as a place where the temperature difference is small, a place where the humidity is low, or a place where ventilation is good.

In this way, by using both the motion data detected by the microwave sensor and the image data detected by the image sensor, it is possible to detect the presence / absence of motion, the amount of motion, the degree of motion, and the tendency of motion, as well as the posture. Can be detected.

  Further, the control unit 7 performs each process performed by the control unit 7 or setting of the process in response to a request obtained through the communication unit 6, or voluntarily or in response to a request from outside the illumination base. In response, the motion data and the image data or related data (hereinafter referred to as “object information”) stored in the recording means of the control unit 7 are output to the communication unit 6.

The usage ratio of each attribute constituting the object information with respect to the transmission capability of the communication unit 6 may be set as appropriate according to the specifications of the object information detection apparatus.

FIG. 3 shows an example of the configuration of the object information detection apparatus according to the present invention, in which the LED luminous body is linked with the motion sensor (microwave Doppler sensor) or an image sensor.
This example takes the form of an incandescent lamp bulb. The base part 1 is the same as that of the incandescent lamp bulb, the body part following the base part 1, the module unit for sealing the opening part of the body part, and the module It is comprised with the fluorescent lid (lens of the said illumination part 3) 8 which covers the whole unit.

  The module unit of this example includes a disk-shaped circuit board, the illumination unit 3, a camera module (second sensor unit 5), a microwave Doppler sensor module (first sensor unit 4), and a communication module (communication). Part 6) and a control module (control part 7), and the body part is equipped with the power supply part 2 therein.

The illumination unit 3 includes a plurality of white LED light emitters and a plurality of red LED light emitters arranged concentrically on the surface of the circuit board with the white LED light emitters outside, and a camera module and a microwave Doppler sensor. Modules are arranged side by side in the center of the circuit board.
The communication module and the control module are arranged side by side on the back surface of the circuit board. In addition, arrangement | positioning of LED light-emitting body and various modules can be changed suitably.
The lens 9 of the camera module is exposed to the outside of the fluorescent lid 8 through a hole provided in a part of the fluorescent lid 8, and a non-translucent frame for blocking the light of the fluorescent lid 8 is provided around the lens 9. Prepare.

The illuminating unit 3 in this example employs a configuration in which a white LED illuminant and a red LED illuminant are used in combination, and either or both of them are lit or blinked according to a command from the control unit 7 (see FIG. 3). ).
As a method for obtaining the light emission and the emergency light emission as the life lighting means or the illuminating device for photographing, in addition to a method of realizing a white LED illuminant alone, red (R), green (G), blue (B ) The three primary color LED light emitters are placed in a single package in a well-balanced manner, all the LED light emitters are turned on to produce white light, and only the red (R) LED light emitting element is made to emit red light. May be taken.

The power supply unit 2 in this example includes a rectifier that converts an AC commercial power supply to a DC power supply, a dimmer (such as PWM dimming or phase control dimming) that adjusts power supply power supplied to the LED light emitter, A waveform shaper that periodically gives a fluctuation component that realizes both a luminance that functions as an illuminating device suitable for living lighting and a luminance as an illuminating device suitable for imaging to a power source that supplies the LED light emitter ( Including an integrating circuit).
The waveform of the fluctuation component may be appropriately selected from waveforms that can be employed, such as a triangular wave shape or a sine wave shape.

The control unit 7 in this example includes a CPU, a ROM, a RAM (recording unit), an input / output port, and a timer.
The control unit 7 includes a detection control unit that controls an operation timing and an operation time of the first sensor unit, an imaging timing and an imaging time of the second sensor unit, and sampling in cooperation with the hardware resource and the software. Imaging control means for controlling the cycle, an analysis unit for deriving one or more events from the output of the first sensor unit or the second sensor unit, and an evaluation unit for deriving anomalies from the single or plural events derived by the analysis unit And the lighting control means which adjusts the lighting timing and lighting time of the said LED is comprised, and there exists each function.

The lighting control means in this example includes a manual switch and switching means such as an illuminance sensor, a temperature sensor, the timer, and a relay that opens and closes by their outputs, and supplies and cuts off the output of the power supply unit 2 to the illumination unit 3 By controlling the light emission cycle or light emission timing, lighting time or extinguishing time of the LED light emitter.
In this example, the lighting control means performs a manual flashing control process, an automatic flashing control process, and a forced dimming control process, and also supplies power to the LED light emitter to the dimmer of the power supply unit 2. A voltage control process or a power control process is performed, and a waveform adjustment process of the fluctuation component is performed.

(Manual blinking control process)
The lighting control means detects a signal accompanying a manual operation such as a switch or a remote control button during the manual blinking control process, and supplies and shuts off power to the LED light emitter.

(Automatic flash control process)
The lighting control means controls the switching means with the timer or the like during the automatic blinking control process, so that the LED light emitter is supplied from the time set as the lighting start time to the time set as the lighting time. Supply power, and compare the output of the illuminance sensor with the threshold of illuminance, and when the illuminance exceeding the threshold is detected, such as on a sunny day, the power to the illumination unit 3 is shut off. When the illuminance lower than the threshold is detected, such as at night, power is supplied to the illumination unit 3.

(Forced dimming control processing)
The lighting control means, for example, detects a possibility of anomaly while photographing and supplying power to the illumination unit 3 in the manual mode or automatic mode during the forced dimming control process. Is necessary, when an abnormality should be detected and an alarm should be issued, when the lighting unit 3 is overheated due to lighting for a long time, or depending on the installation location, the sensor unit (the first sensor unit 4 and the second sensor unit). Sensor unit 5) When there is a possibility of dew condensation on the surface, a process of supplying power having a predetermined luminance to the white LED light emitter or red LED light emitter constituting the illumination unit 3 at a predetermined timing is performed.

When the lighting control means evaluates that there is a possibility of abnormality in the preliminary evaluation described later, the brightness of the LED light emitter is changed by the imaging element by changing the setting of the dimmer or the like of the power supply unit 2. The light can be automatically adjusted so that the brightness is suitable for imaging.
The lighting control means further adjusts the color or blinking mode of the LED luminous body by changing the setting of the switching means or the timer, etc., when it is evaluated as abnormal in the final evaluation described later. Various information can be provided only by flashing the light emitter.
For example, when an abnormality in heartbeat or breathing or an abnormality in stop or physical condition is detected, control such as blinking according to the heartbeat or breathing timing of the user is performed on the switching means as an alarm. Can do.

The lighting control means, for example, by controlling the operation of the switching means such as changing the setting of the timer when the temperature sensor detects overheating of the lighting unit 3 due to continuous lighting for a long time, The energization time of the LED emitter is controlled. At that time, considering the resolution of the human eye, if there is a certain period of extinction time that is not perceived during the period of continued lighting, LED light emission is not noticed by those who use living lighting Heat generation of the body can be suppressed.
As a result, not only a metal case such as aluminum but also a resin case can be used as the outer case, and costs can be reduced.

  In the lighting control means, for example, the temperature in the vicinity of the sensor unit surface is equal to or higher than the saturated water vapor temperature (the temperature at which a saturated water vapor amount equal to or higher than the water vapor contained in the atmosphere in the vicinity of the sensor unit surface in the installation chamber) can be obtained. Or less than the temperature at which the light is deformed) the power supplied to the LED light emitter or the LED light emitter in such a manner that the setting of the timer, the setting of the dimmer of the power supply unit 2 or the operation of the switching means is controlled. By controlling the blinking period or blinking period (hereinafter referred to as “residual heat control”), the surface of the first sensor unit 4 or the lens surface of the second sensor unit 5 in a bathroom or kitchen (hereinafter “sensor unit surface”) A dew condensation prevention means for preventing dew condensation).

  In order to detect the possibility of condensation, a temperature sensor for detecting the surface of the sensor unit or the ambient temperature in the vicinity thereof (hereinafter referred to as “near temperature”) is integrally provided in the vicinity of the surface of the sensor unit. The dew condensation prevention means performs the residual heat control according to the sensor output or the vicinity temperature estimated from the output of the illuminance sensor, and individual residual heat control starts depending on the location where the object information detection device of this example is installed The temperature can be individually set via the communication unit 6 including communication means such as the PLC.

  In addition, the control unit 7 emits LED light for processing to prevent overheating of the illumination unit 3 at night (in the dark) (overheating prevention processing), for capturing images at night or for preventing condensation in a humid space. When performing the residual heat control of the body, the power supply time (lighting time) to the LED light emitter is set to be shorter (less than 100 ms, preferably less than about 50 ms) exceeding the resolution of the human eye when recognizing light emission. In addition, the power supply unit 2 can be controlled so as to blink at a cycle that is not perceived as being continuously lit (preferably a cycle equivalent to 50 cycles or more of the commercial power supply).

In this way, by controlling the blinking of the LED light emitter, even when the LED light emitter is turned on at night (dark place), it is possible to avoid disturbing the user's sleep as much as possible. If the sharp blinking of the edge is performed in a short time, the flash function of the camera can be achieved.
At that time, the imaging control means sets the imaging time of the imaging device within the lighting time that cannot be perceived by human eyes as described above in order to save the image data acquired by the imaging device.

The detection control means in this example normally operates the motion sensor of the first sensor unit 4 at a constant detection period given by the timer or continuously throughout the day.
The detection cycle is a cycle that can be detected once or a plurality of times in one cycle of the fluctuation component of the power supply voltage, and a multiplication frequency of the frequency of the fluctuation component of the power supply voltage so that motion data can be collected under the same environment as much as possible. It is desirable that the period be

The imaging control means of this example causes the second sensor unit 5 to perform imaging at a constant detection cycle given by the timer.
The detection cycle is a cycle that can be detected once or a plurality of times in one cycle of the fluctuation component of the power supply voltage of the LED light emitter, and particularly in the case of one detection, the illuminance is different under the different phases of the fluctuation component as much as possible. It is desirable that the period is difficult to synchronize with the fluctuation component of the power supply voltage so that image data can be collected below.

  The analysis unit in this example guides an event occurring in the test object from the motion data detected by the first sensor unit 4 and the image data detected by the second sensor unit 5, and attributes of the event And event detection means for storing event data including date and time in the RAM, and information sorting means for discarding the motion data or the image data when these events cannot be derived from the motion data and the image data.

As described above, the control unit 7 adopts a control method capable of photographing under various illuminances by the imaging control unit, and includes the information sorting unit, so that a valid image and an invalid image are sorted out by software. Only by the selection process, it is possible to avoid saving the image data that is unsuitable for analysis such as overexposure or underexposure while periodically saving an effective image.
As a result, it is no longer necessary to perform complicated processing assuming various situations, such as a method of actively performing phase control by detailed switching focusing on the time when an effective image is obtained, and the actual situation of the user It is possible to flexibly respond to the addition and update of functions according to the situation by only changing the software.

For example, when this example is used in a watch system for watching a user's living body, the analysis unit uses the motion data detected by the first sensor unit 4 as the event, such as a user's heartbeat, respiration, and The apparatus may include the event detection unit that guides the body movement and guides the posture of the user as the event from the image data detected by the second sensor unit 5.
Information storage in the analysis unit, if a method of storing the posture derived from the image calculation by posture calculation, etc., with numerical data indicating its attributes, etc., rather than storing the image data itself in the RAM as described above, The storage area is saved, and the equipment cost is also low.

If the object information detection apparatus is provided with the analysis unit, it is possible to save a storage area and a transmission amount to be secured for the object information detection apparatus as a device for detecting a specific event.
On the other hand, when the object information detection device includes the analysis unit in an external device such as a router that communicates with the object information detection device, a specific standard for separating valid images and invalid images from the object information detection device. Therefore, the versatility of the object information detection apparatus can be enhanced without limiting the events to be detected.

  In this example, the evaluation unit includes an abnormality detection unit that derives an abnormality from the event derived by the analysis unit, and an abnormality history storage unit that stores abnormality data including the abnormality attribute and date and time derived by the abnormality detection unit in the RAM. Is provided.

  For example, when this example is used in a monitoring system for watching a living body of a user, the evaluation unit may detect heart disease, brain disease from events such as heartbeat, breathing or body movement or posture guided by the analysis unit. Alternatively, it may be configured to include an abnormality detecting means for introducing an abnormality such as a fall or injury, an abnormal or stopped heartbeat or breathing, or an abnormal posture or movement.

The evaluation unit performs preliminary evaluation that leads to the possibility of abnormality by a relatively simple process, and determination of abnormality that evaluates whether or not the abnormality is more precise by processing only when the possibility of abnormality is detected. Do.
The preliminary evaluation method is a first method for detecting a possibility of abnormality from any of the events obtained by the first sensor unit 4 (for example, heart rate, respiratory rate or body movement) or a combination thereof, Furthermore, the 2nd method etc. which detect the possibility of abnormality from any of the event which added the event (for example, attitude | position etc.) detected by the 2nd sensor part 5, or those combinations are mentioned.

In the first method, sampling for preliminary evaluation is always performed in the first sensor unit 4, and the numerical value of each event obtained there, the numerical value indicating the degree of each event, or a numerical value combining them, When the threshold value is exceeded or the threshold value is not reached, it is evaluated that there is a possibility of abnormality.
In the second method, the first sensor unit 4 and the second sensor unit 5 always perform the preliminary evaluation sampling, and the numerical value of each event obtained there, the numerical value indicating the degree of each event, or A numerical value obtained by combining them, and when the threshold value is exceeded or the threshold value is not reached, it is evaluated that there is a possibility of abnormality.

The second sensor unit 5 at the time of preliminary evaluation in the second method performs sampling with a relatively low resolution and a relatively long period.
For example, when evaluating the posture, the abnormality detection means of this example, from the image data detected at a relatively low resolution by the image sensor in the preliminary evaluation, from the user's vertex, base and center of gravity, A posture composed of a standing position, a sitting position, a forward bending position, a prone position, and a supine position is derived, and the image data that can be derived from the posture is stored in the RAM as an effective image, and an abnormality or normality of the detected position is determined.
For example, it is determined that there is a possibility of abnormality when the posture of the user is not common sense as the posture at the detected position, such as detecting the supine position in a bathroom or bathroom.
When the posture cannot be derived from the image data, the information classification unit discards the image as invalid image data.

The second sensor unit 5 at the time of the definitive evaluation in the first method performs the sampling of the image data at the resolution or period required for the application, thereby confirming the authenticity of the abnormality detected in the preliminary evaluation. Validate.
On the other hand, the second sensor unit 5 at the time of definitive evaluation in the second method performs the preliminary evaluation by sampling the image data at a higher resolution or shorter cycle than the preliminary evaluation in the second method. The authenticity of the possibility of abnormality detected in step 1 is verified.

At that time, referring to the output of the illuminance sensor, when the illuminating unit 3 is in an underexposed state in a dark place, it switches to the forced dimming control process, and the DC power source is switched on to the LED light emitter. Supply or further change the setting of the dimmer to adjust the LED luminous body to a brightness suitable for imaging.
In the definite evaluation, a method of sampling the motion data by the first sensor unit 4 at a cycle shorter than the preliminary evaluation can be adopted.

For example, in the preliminary evaluation, when there is a possibility of abnormality from any one of heart rate, respiration rate, body movement or posture, or a combination thereof, the abnormality detection means uses the image sensor as the definite evaluation. Based on the image data detected under preferable illuminance and the image data detected by shooting at a higher resolution, the posture and orientation of the user is reconfirmed, and the posture changes from the effective image before and after the effective image. The presence or absence and the facial expression of the user are guided to determine whether it is abnormal or normal.
The abnormal data as abnormalities in the definitive evaluation when a physically difficult posture for the user, a posture that is impossible at the detection location, a constant posture over a long period of time or a constant motion, or an expression of convulsions or bitterness is detected. Is output.

The analysis unit and the evaluation unit may be configured not to function as the function of the object information detection device, depending on the configuration of a system using the object information detection device.
For example, when the object information detection device has a system configuration that outputs the abnormal data independently and further outputs an alarm corresponding thereto (see FIG. 4A), as described above, It is set as the structure which comprises both the said evaluation parts (refer FIG. 1 or FIG. 3).

  On the other hand, when positioning the object information detection device, for example, as a sensor for detecting a user's bitile sign such as a user's heartbeat, respiration, or body motion, or a sensor for detecting a signal for guiding those events, Connected to a router that communicates with the object information detection device, a local network such as LAN or Bluetooth (see FIG. 4B), or a global network via them (see FIG. 4C) The terminal or the information management center can share the functions of the analysis unit or the evaluation unit (see FIG. 2).

If the control unit 7 adopts a configuration in which the setting of the timer, the dimmer or the switching means can be appropriately changed from the outside via the communication unit 6, the function of the timer or the like can be achieved. The operating cycle and operating time of the first sensor unit 4 and the second sensor unit 5 can be changed from the outside through the detection control unit and the imaging control unit to be used.
In a system using a plurality of object information detection devices, if an ID is assigned to each control unit 7 for each object information detection device, the first sensor unit 4 and the second sensor unit 5 are operated according to the installation location. Different settings can be made for the ratio.

The communication unit 6 in this example includes a communication modem such as a PLC module that performs power line carrier communication, and a wireless communication interface such as WIFI and Bluetooth (registered trademark).
For example, the PLC module is a signal capable of communicating data stored in the RAM of the control unit 7 in accordance with a command of the control unit 7 or in accordance with a period (for example, 10 kHz to 450 kHz) generated by the timer. And processing for demodulating the received data from the power line so that the control unit 7 can process it.
The communication unit 6 places the image data on the power line mainly when the LED light emitter is turned on, and places the motion data on the power line mainly when the LED light emitter is turned off.

FIG. 2 shows an example in which the object information detection apparatus (“illumination sensor” in the figure) is watched over and adopted in the system.
In this example, a sensor installed in a residence where a monitoring target (user) resides detects the biological information of the monitoring target and surrounding environmental information, and receives and obtains information from the sensor to analyze and store the information. And a router that performs output according to the analysis result and an alarm device that operates according to the output (see FIG. 2).

The alarm device in this example includes an audio device such as a speaker, a buzzer, an indicator lamp, a nurse call, and an emergency notification device that notifies various specialized institutions.

  The router in this example includes a CPU 1 for function update support, a CPU 2 for data analysis / storage, a PLC modem, a serial port, an audio output, a contact input, a contact output, a wired / wireless LAN port, a USB port, and a wireless communication interface. These are used to perform data communication with an external terminal device or an information management center.

The object information detection apparatus according to the present invention is not limited to the watching system, but can be used in various ways using the motion data and the image data only by changing the specifications of the analysis unit and the evaluation unit as desired by the user. It can be realized as a system (see FIG. 4B).
For example, when used in a system linked with a router or various networks using the motion data and the image data output from the object information detection device, the router or terminal device detects the desired event and symptom. By simply changing the specifications of the analysis unit and the evaluation unit, the same object information detection apparatus can be realized as a system for other uses desired by the user.

  If the object information detection device is used as a remote system that can cooperate with an external organization using a router and the Internet, a remote setting system for control content, a remote monitor system for detection content, or a history data storage / viewing system thereof, It can be used as a global system in which user information can be shared by various organizations permitted to use it in the form of an emergency call system that automatically detects related risks and automatically notifies relevant organizations (FIG. 4). (See (C)).

  At that time, the image data is subjected to internal processing by the object information detection device or router, and the ID and the abnormal data other than the outside data are designed to be outside (images and the like are not outside). The communication between the object information detection device and the router is also preferably performed using an encrypted signal or data.

The object information detection device according to the present invention can be configured to notify the possibility of abnormality or the presence of an abnormality, and is configured to notify the possibility of abnormality or the absence of an abnormality (hereinafter referred to as “normal”). You can also
In the latter case, for example, in addition to the normality, the basis thereof (the object information detection device installed in the accommodation facility, the nursing facility, the hospital, or the like has not detected a fear or abnormality) It can be set as the structure which always alert | reports to an internal or external organization etc. through the part 6.

By adopting this method, for example, even if the report is reset before the disappearance of the abnormality or the arrival of the rescuer, it does not immediately cancel the abnormality, and transmission of the normal basis is interrupted. The alarm state to the related organizations will be maintained.
In other words, the procedure does not require a cancellation procedure.
