Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the prior art as described above, there is a risk that a sensor for measuring the respiratory rate or the like of the person to be confirmed for safety may misdetect the measurement target. In addition, when the sensor attempts to measure the respiratory rate or the like even when there is no target person in the detection range, there is a problem that the processing load of the system increases.

[0006] One aspect of the present invention has been made in view of the above-mentioned problems, and aims to suppress false detections and increased processing load in a system for confirming the safety of a person. [Means for solving the problem]

[0007] To solve the above problems, a safety confirmation system according to one aspect of the present invention comprises: a first sensor that non-contactly senses the biological information of a target person within a predetermined detection range; a second sensor that non-contactly detects a target person within the detection range of the first sensor; and a control unit that controls the first sensor and the second sensor, which, when the second sensor detects that the target person is present in the detection range, causes the first sensor to measure the biological information of the target person. The control unit, when the second sensor corresponding to the first detection range and the second sensor corresponding to the second detection range detect that the target person has moved from the first detection range to a second detection range adjacent to the first detection range, combines the biological information data of the target person measured by the first sensor corresponding to the first detection range and the biological information data of the target person measured by the first sensor corresponding to the second detection range into a continuous series of data.

[0008] Each aspect of the present invention may be implemented by a computer, in which case a control program for the safety confirmation system that implements the safety confirmation system by a computer by operating the computer as each part (software element) of the safety confirmation system, and a computer-readable recording medium on which the control program is recorded also fall within the scope of the present invention. [Effects of the Invention]

[0009] According to one aspect of the present invention, it is possible to suppress false detections and increased processing load in a system for confirming the safety of a person. [Brief explanation of the drawing]

[Figure 2] This diagram shows an overview of the safety confirmation system. [Figure 3] This figure shows an example of the installation of the first and second sensors.

[Figure 6] This is a flowchart showing the processing flow in the safety confirmation system. [Figure 7] This figure shows an example of a threshold value that is compared with the measurement results of the second sensor. [Modes for carrying out the invention]

[0011] [Embodiment] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. While the embodiments described below include various technically preferred limitations for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0012] [Overview] First, an overview of the safety confirmation system 1 according to this embodiment will be described with reference to Figure 1. Figure 1 is a diagram showing an overview of the safety confirmation system 1. As shown in Figure 1, safety confirmation The recognition system 1 is a system that checks whether there are any abnormalities in the heart rate, etc., of residents in the living room 10 within the house, and if an abnormality is found, it sends an alert to an external device, for example, operated by an operator.

[0013] Hereinafter, the safety confirmation system 1 will be described assuming it is installed in the living room 10, but it is not limited to this, and part or all of the system may be installed in a facility such as a hospital, or in any space of your choice.Hereinafter, the person whose safety is confirmed by the safety confirmation system 1 may be referred to as the person concerned.

[0014] FIG. 2 is a diagram showing an overall overview of the safety confirmation system 1. As shown in FIG. 2, the safety confirmation system 1 includes a first sensor 41, a second sensor 42, a control unit 30, a storage unit 50, and a communication unit 43.

[0015] The first sensor 41 non - contact senses the biometric information of the subject within the detection range and acquires the biometric information. Specifically, at least one of the heart rate, respiratory rate, body temperature, and blood pressure of the subject is non - contact sensed. In the present embodiment, an example will be described in which the first sensor 41 non - contact senses at least one of the heartbeat and respiration of the subject within the detection range and measures at least one of the heart rate and respiratory rate of the subject. However, the configuration in which the first sensor 41 non - contact senses and measures other biometric information is also included in the present disclosure. Hereinafter, the first sensor 41 will be described as a Doppler sensor, but it is not limited to the Doppler sensor. For example, an infrared array sensor, an FMCW radar (Frequency Modulated Continuous Wave radar), or the like may be used.

[0016] The second sensor 42 non - contact detects the number of subjects within the detection range. Hereinafter, the second sensor 42 will be described as a pyroelectric sensor, but it is not limited thereto, and other sensors capable of performing the above - described detection may be used. When the second sensor 42 is a pyroelectric sensor, the subject is detected by sensing the infrared rays radiated from the subject.

[0017] Also, at least a part of the detection range of the first sensor 41 and the detection range of the second sensor 42 may overlap, and one may be included in the other. For example, the detection range of the second sensor 42 may be wider than the detection range of the first sensor 41. Also, one being included in the other includes the case where they are the same.

[0018] In addition, the detection range of the first sensor 41 and the detection range of the second sensor 42 may be ranges in the same direction starting from each sensor. In other words, the first sensor 41 and the second sensor 42 may be provided on the same wall surface, ceiling or floor, built-in shelves, furniture, etc., and may be configured to radiate in the same direction. In addition to the above configurations, there are configurations in which one sensor is provided on the ceiling facing the floor direction and the other sensor is provided on the floor surface facing the ceiling direction.

[0019] Figures 3 to 5 are diagrams showing installation examples of the first sensor 41 and the second sensor 42. However, in Figure 5, for the convenience of reference in the following description, each of the first sensors 41 is illustrated as first sensors 41a to 41d, and each of the second sensors 42 is illustrated as second sensors 42a to 42d.

[0020] Figures 3 to 5 illustrate a configuration in which the first sensor 41 and the second sensor 42 are installed on the ceiling and radiate toward the floor surface. Also, in Figures 3 to 5, each sensor is provided in the vicinity and radiates in the same direction, and the detection range of the first sensor 41 and the sensing range of the second sensor 42 are the same.

[0021] In addition, at least one of the first sensor 41 and the second sensor 42 included in the safety confirmation system 1 may be plural as shown in Figure 1 and the like. The same applies to other components of the safety confirmation system 1. Also, the detection ranges of the plurality of first sensors 41 or the detection ranges of the plurality of second sensors 42 may partially overlap each other.

[0022] Figures 4 and 5 illustrate a configuration in which a plurality of the first sensor 41 and the second sensor 42 are provided in the same room of the living room 10. In the case of such a configuration, by the cooperation of the plurality of each sensor, it is possible to cope with the case where the body of the target person straddles a plurality of detection ranges (detection ranges).

[0023] The control unit 30 controls the first sensor 41 and the second sensor 42, etc., and is a control device that oversees the entire safety confirmation system 1, and also functions as a determination unit 31, an alarm unit 32, and a communication control unit 33.

[0024] Furthermore, when the control unit 30 detects that the subject is within the detection range of the first sensor 41, it controls the first sensor 41 to measure at least one of the subject's heart rate and respiratory rate.

[0025] The determination unit 31 makes a determination regarding the detection results of the first sensor 41 and the second sensor 42. Details of this determination will be described later.

[0026] When the determination unit 31 determines that an abnormality has occurred with the subject, the notification unit 32 sends information to the reception management unit (external device) 25 via the communication unit 43. Here, the external device may be, for example, a terminal device operated by an operator as shown in Figure 1, or a mobile device owned by a family member of the subject. The reception management unit 25 may be operated by an operator, but some or all of the operator's work may be replaced by machine learning such as AI. Since the amount of data related to reception handled by the operator is large, it is also useful to generate judgment information using machine learning such as AI. The communication control unit 33 controls the communication processing performed by the communication unit 43.

[0027] The memory unit 50 is a storage device that stores at least a threshold 51 which is compared with the measurement result of the first sensor 41. The memory unit 50 may also store the subject's normal biological information (data related to physical characteristics such as age, gender, height, and weight, and data such as heart rate), behavioral information (information on behavioral patterns by day of the week, time of day, etc.), etc. The threshold 51 may also be calculated by the control unit 30 by referring to at least one of the subject's biological information and behavioral information. In addition, information indicating the subject's heart rate or respiratory rate measured by the first sensor 41 is stored in the memory unit 50 by the control unit 30. The communication unit 43 is an interface for communication with external devices.

[0028] In addition, in a configuration different from that shown in Figure 2, at least one of the control unit 30, the storage unit 50, and the communication unit 43 may be configured to include at least one of the first sensor 41 and the second sensor 42. Furthermore, the safety confirmation system 1 may also include, for example, an input unit (not shown) that receives user input of information stored in the storage unit 50, which may be implemented as buttons on a keyboard or a touch panel. Alternatively, the information stored in the storage unit 50 may be information entered via a mobile terminal such as a smartphone and acquired by the control unit 30 via the communication unit 43.

[0029] [Processing flow in Safety Confirmation System 1] Next, the processing flow in the safety confirmation system 1 will be explained with reference to Figures 5 to 7.

[0030] First, let's elaborate on Figure 5. In the living room 10 shown in Figure 5, the detection range of the first sensor 41a and the second sensor 42a is region A. The detection range of the first sensor 41b and the second sensor 42b is region B. The detection range of the first sensor 41c and the second sensor 42c is region C. The detection range of the first sensor 41d and the second sensor 42d is region D. When the first sensors 41a to 41d are not specifically distinguished, some or all of them may be referred to as the first sensor 41. Similarly, when the second sensors 42a to 42d are not specifically distinguished, some or all of them may be referred to as the second sensor 42.

[0031] Furthermore, the entrance / exit 60 for entering and exiting the living room 10 in Figure 5 is provided only on the outside of area A. As a result, in order to go from outside the living room 10 to areas B to D, it is necessary to go through area A. In addition, although not required, a second sensor 42e (not shown) is provided separately near the entrance / exit 60.

[0032] Figure 6 is a flowchart showing the processing flow in the safety confirmation system 1. The processing shown in the flowchart of Figure 6 is initiated when the second sensor 42e, or another second sensor 42, detects a person entering the room 10.

[0033] The first sensors 41a to 41d begin the process of irradiating with microwaves and sensing the reflected microwaves (S101). Here, the frequency of the reflected microwaves is Doppler-shifted according to the movement of the irradiated object. Note that it is not mandatory to perform the microwave irradiation process in this step, and it may be performed immediately before the process in step S103, which will be described later.

[0034] Next, the determination unit 31 determines whether or not any of the second sensors 42 has detected the presence of a subject within the detection range of the first sensor 41 (S102). If the determination unit 31 determines that any of the second sensors 42 has made the above detection (YES in S102, detection step), the first sensor 41 then executes the process in step S103. If the determination unit 31 determines that none of the second sensors 42 have made the above detection (NO in S102), the process in step S102 continues until any of the second sensors 42 detect a subject.

[0035] However, although not limited to this, if any of the second sensors 42 detect multiple subjects within their detection range, the transition to step S103 may not occur, and the processing in step S102 may continue. This is because, if multiple subjects are in close proximity, it can be assumed that they will be able to notice each other that an anomaly has occurred. Furthermore, this can suppress erroneous measurements caused by interference from other people being located near a subject being measured. However, even if multiple subjects are present in the room 10, if these multiple subjects are detected in different detection ranges of the multiple second sensors 42, the first sensor 41 may then proceed to perform the processing in step S103. This configuration is particularly advantageous when the room 10 is sufficiently large and the second sensors 42 that detected each subject are far apart.

[0036] Next, the first sensor 41 corresponding to the second sensor 42 that performed the above detection starts measuring the heart rate and respiratory rate of the subject by referring to the reflected microwaves mentioned above (S103, measurement step). Here, the first sensor 41 corresponding to the second sensor 42 means the first sensor 41 having the same detection range as the target second sensor 42. For example, if the second sensor 42a detects that there is only one subject within the detection range of the first sensor 41a, the first sensor 41a starts measuring the heart rate and respiratory rate of that subject. However, the first sensor 41a may also start the measurement if the second sensor 42a detects that there are multiple subjects within the detection range. In these cases, the first sensors 41b to 41d, which do not have subjects within their detection range, do not measure heart rate and respiratory rate.

[0037] Next, the determination unit 31 determines whether the second sensor 42 has detected that the subject has moved into an adjacent detection range (area) while the first sensor 41 is measuring heart rate and respiratory rate (S104). If the determination unit 31 determines that the second sensor 42 has detected that the subject has moved into an adjacent detection range (YES in S104), the process in step S105 is then executed. If the determination unit 31 determines that the second sensor 42 has not made the above detection (NO in S104), the process in step S106 is then executed.

[0038] Next, the first sensor 41 corresponding to the detection range from which the subject moved ends measuring heart rate and respiratory rate, and the first sensor 41 corresponding to the detection range to which the subject moved begins measuring the heart rate and respiratory rate of that subject (S105). For example, if the subject moves from area A to area B, the first sensor 41a ends measuring the subject's heart rate and respiratory rate, and the first sensor 41b takes over and performs the above measurements. The data measured by these first sensors 41 are treated as a series of data.

[0039] In other words, when the second sensor 42 corresponding to the first detection range and the second sensor 42 corresponding to the second detection range detect that the subject has moved from the first detection range to the second detection range adjacent to the first detection range of the first sensor 41, the control unit 30 stores the data of the subject's heart rate and respiratory rate measured by the first sensor 41 corresponding to the first detection range and the data of the subject's heart rate and respiratory rate measured by the first sensor 41 corresponding to the second detection range as a continuous series of data in the storage unit 50.

[0040] Furthermore, steps S104 and S105 can be executed multiple times. That is, each time the subject moves into an adjacent detection range of the second sensor 42, the first sensor 41 that measures heart rate and respiratory rate switches to the one corresponding to the second sensor 42. In addition, each measurement data is stored in the storage unit 50 as a series of data.

[0041] Next, the determination unit 31 determines whether the measurement result of the first sensor 41 is within the range of values ​​defined by the threshold 51 stored in the memory unit 50 (hereinafter sometimes simply referred to as "within the range of values") (S106). Figure 7 is a diagram showing an example of the threshold 51. Here, "BPM (Beats Per Minute)" in Figure 7 refers to the number of beats, etc., per minute. For example, in the case of heart rate as exemplified in Figure 7, the determination unit 31 determines that the measurement result of the first sensor 41 is within the range of values ​​if the subject's heart rate per minute is 40 or more and 130 or less, and otherwise determines that it is outside the range of values ​​defined by the threshold 51 stored in the memory unit 50 (hereinafter sometimes simply referred to as "outside the range of values"). In the case of respiratory rate, the determination unit 31 determines that the measurement result of the first sensor 41 is within the range of values ​​if the subject's respiratory rate per minute is 8 or more and 30 or less, and otherwise determines that it is outside the range of values.

[0042] Furthermore, as described above, the threshold 51 compared with the measurement result of the second sensor 42 may correspond to at least one of the subject's normal biological information and behavioral information. That is, although Figure 7 illustrates a simplified configuration of the threshold 51, it is not limited to this, and the determination unit 31 may use different thresholds 51 for determination depending on the subject's age or gender, or attributes such as exercise habits.

[0043] If the determination unit 31 determines that the measurement result of the first sensor 41 is outside the range of values ​​(YES in S106), the alarm unit 32 then executes the process in step S107. If the determination unit 31 determines that the measurement result of the first sensor 41 is within the range of values ​​(NO in S106), the process in step S102 is executed again.

[0044] In addition, as an alternative to step S106, the determination unit 31 may refer to a plurality of measurement results from the first sensor 41 within the most recent predetermined time and determine whether the proportion of measurement results that are determined to be outside the range of values ​​for at least one of the subject's heart rate and respiratory rate is greater than or equal to a predetermined proportion. In the above configuration, if the determination unit 31 determines that the proportion of the plurality of measurement results that are determined to be outside the range of values ​​is greater than or equal to a predetermined proportion (YES in S106), the alarm unit 32 then executes the process in step S107. If the determination unit 31 determines that the proportion is less than the predetermined proportion (NO in S106), the process in step S102 is executed again.

[0045] Next, the notification unit 32 sends information indicating that an abnormality has occurred with the target person to the reception management unit (external device) 25 via the communication unit 43 (S107). Subsequently, the reception management unit 25 may automatically make inquiries, for example, to the residence having the room 10 where the safety confirmation system 1 is installed, regarding the safety of the target person.

[0046] Furthermore, the process shown in the flowchart of Figure 6 may be performed until the second sensor 42e and the second sensors 42a to 42d detect that all subjects have left the room 10. Also, once it is detected that all subjects have left the room 10, the first sensor 41 may terminate the process of irradiating with microwaves and sensing the reflected microwaves.

[0047] According to the method described above with reference to the flowchart in Figure 6, false positives and increased processing load in the method for confirming the safety of the subject can be suppressed. Furthermore, if no abnormality occurs with the subject, it is possible to understand the subject's daily routine, such as which room in the house the subject spends the most time in.

[0048] <Additional Notes> It is not necessarily required that the safety confirmation system 1 includes a communication unit 43 and that the control unit 30 functions as an alarm unit 32. For example, the control unit 30 may be configured to notify the person concerned by sounding a buzzer or the like when it determines that an abnormality has occurred.

[0049] Furthermore, the measurement by the first sensor 41 and the determination based on the measurement results may be configured to perform only one of either heart rate or respiratory rate.

[0050] Furthermore, if the measurement result of the first sensor 41 is equal to the threshold value 51 described above, the system may be configured to determine that the measurement result is within the range of values, or it may be configured to determine that it is outside the range.

[0051] Furthermore, the living room 10 may be equipped with a switch that enables or disables the function of at least one of the first sensor 41 and the second sensor 42 installed in the living room 10. For example, when the person exercises in the living room 10, operating the switch to temporarily disable the function of each sensor can prevent the safety confirmation system 1 from mistakenly determining that there is an abnormality in the person's heart rate or respiratory rate.

[0052] 〔summary〕 The safety confirmation system according to Embodiment 1 of the present invention comprises: a first sensor that non-contactly senses the biometric information of a target person within a predetermined detection range; a second sensor that non-contactly detects the number of target people within the detection range of the first sensor; and a control unit that controls the first sensor and the second sensor, which, when the second sensor detects that only one target person is present within the detection range, causes the first sensor to measure the biometric information of the target person.

[0053] With the above configuration, the first sensor only performs a measurement when the second sensor detects that only one person is within the detection range of the first sensor. This suppresses false detections and increased processing load in the system for confirming the safety of the person.

[0054] In the safety confirmation system according to aspect 2 of the present invention, in aspect 1 described above, if the second sensor detects that the subject, who was the only person present in the detection range, has left the detection range, the first sensor may terminate the measurement of the subject's biometric information.

[0055] With the above configuration, measurement by the first sensor ends when the target person is no longer within the detection range, which helps to suppress false detections and increases in processing load.

[0056] In the safety confirmation system according to aspect 3 of the present invention, in aspect 1 or 2 described above, when a second sensor corresponding to the first detection range and a second sensor corresponding to the second detection range detect that the subject, who was the only person present, has moved from the first detection range to a second detection range adjacent to the first detection range, the system may be configured to combine the biometric information data of the subject measured by the first sensor corresponding to the first detection range and the biometric information data of the subject measured by the first sensor corresponding to the second detection range into a continuous series of data.

[0057] With the above configuration, the series of measurements by the first sensor can continue even when the user moves between multiple detection ranges.

[0058] In the safety confirmation system according to aspect 4 of the present invention, in any of the above aspects 1 to 3, the detection range of the second sensor may be configured to be wider than the detection range of the first sensor.

[0059] According to the above configuration, a system can be implemented using a second sensor with a number equal to or less than the first sensor, in which the biological information of a subject is measured when the user is within the detection range of the first sensor.

[0060] In the safety confirmation system according to aspect 5 of the present invention, in any of the above aspects 1 to 4, the first sensor may be configured to measure at least one of the heart rate and respiratory rate of the subject.

[0061] According to the above configuration, it is possible to check the safety of the subject based on their heart rate or respiratory rate.

[0062] A control device according to embodiment 6 of the present invention controls a first sensor that non-contactly senses the biological information of a subject within a predetermined detection range, and a second sensor that non-contactly detects the number of subjects within the detection range of the first sensor. When the second sensor detects that only one subject is present within the detection range, the first sensor is configured to measure the biological information of the subject.

[0063] The above configuration contributes to the realization of the safety confirmation system described above.

[0064] A living room according to embodiment 7 of the present invention is a living room comprising: a first sensor that non-contactly senses the biological information of a subject within a predetermined detection range in the living room; a second sensor that non-contactly detects the number of subjects within the detection range of the first sensor; and a control device that controls the first sensor and the second sensor, which, when the second sensor detects that only one subject is present within the detection range, causes the first sensor to measure the biological information of the subject.

[0065] With the above configuration, it is possible to create a living space that has the same effect as the safety confirmation system described above.

[0066] A method for confirming the safety of a person according to aspect 8 of the present invention includes: a sensing step using a first sensor installed in a living room that non-contactly senses the biometric information of a person within a predetermined detection range in the living room; a detection step using a second sensor installed in the living room that non-contactly detects the number of people within the detection range of the first sensor; and a measurement step in which, if the second sensor detects that only one person is present within the detection range, the first sensor measures the biometric information of the person.

[0067] The above configuration will produce the same effect as the safety confirmation system described above.

[0068] [Examples of implementation using software] The control blocks included in the safety confirmation system 1 (particularly the determination unit 31, alarm unit 32, and communication control unit 33 of the control unit 30) may be implemented by logic circuits (hardware) formed on an integrated circuit (IC chip) or the like, or by software.

[0069] In the latter case, the safety confirmation system 1 includes a computer that executes instructions for a program, which is software that implements each function. This computer includes, for example, one or more processors and a computer-readable recording medium that stores the program. The objective of the present invention is achieved when the processor reads the program from the recording medium and executes it in the computer. For example, a CPU (Central Processing Unit) can be used as the processor. As the recording medium, a "tangible medium that is not temporary," such as ROM (Read Only Memory), can be used, as well as tape, disk, card, semiconductor memory, programmable logic circuit, etc. It may also further include RAM (Random Access Memory) for deploying the program. Furthermore, the program may be supplied to the computer via any transmission medium capable of transmitting the program (such as a communication network or broadcast waves). In one aspect of the present invention, the program can also be realized in the form of a data signal embedded in a carrier wave, which is embodied by electronic transmission.

[0070] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
