Description

[Technical Field]

[0001] The present invention relates to a monitoring system that measures multiple monitoring items indoors for a person to be monitored, and more particularly to a monitoring system that displays a display image including monitoring item information for each of the multiple monitoring items on a screen. [Background technology]

[0002] Currently, it is desirable to provide nursing or care at an appropriate time to those who need nursing or care. In order to protect the privacy of those who need nursing or care and from the viewpoint of the need for manpower, it is preferable that the monitoring of those who need nursing or care does not involve human intervention. For this reason, those who need nursing or care (those who are being monitored) are sometimes monitored using sensors or the like.

[0003] For example, Patent Document 1 describes an information providing device that includes an acquisition unit that acquires detection information detected by sensors installed on building materials, furniture, devices, or equipment installed in a living space, a storage unit that stores the detection information acquired by the acquisition unit, and a generation unit that generates information to be provided regarding the status of residents living in the living space based on changes over time in the detection information stored in the storage unit. Patent Document 1 describes that information to be provided is generated for each type of behavior of the residents in their daily lives. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-18760 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, in Patent Document 1, provided information is generated for each type of movement of the resident in daily life. However, although provided information can be obtained for each type of movement of the resident in daily life in Patent Document 1, it is difficult to grasp the state of the resident.

[0006] Therefore, the present invention has been made in consideration of the above problems, and an object of the present invention is to provide a monitoring system that makes it easy to visually grasp the physical condition of a person being monitored. [Means for solving the problem]

[0007] The above problem is solved by the monitoring system of the present invention, which includes a measuring instrument that measures multiple monitoring items indoors for a monitored person and outputs signals corresponding to the measurement results of the multiple monitoring items, and an output device that outputs monitoring item information corresponding to the measurement results of the multiple monitoring items based on the signals corresponding to the measurement results of the multiple monitoring items, and the output device displays a display image on a screen that includes monitoring item information for each of the multiple monitoring items.

[0008] In the monitoring system of the present invention configured as described above, the physical condition of the person being monitored can be easily grasped visually.

[0009] In the above monitoring system, it is preferable that the output device displays, among the monitoring item information, a plurality of pieces of behavior information relating to the behavior of the monitoring target person using a common time axis. According to the above configuration, it becomes possible to visually and easily grasp what actions the person being monitored has taken in chronological order.

[0010] Furthermore, in the above monitoring system, it is more preferable that the output device provides a column for each piece of monitoring item information in the display image and displays a marker indicating the monitoring item information in each column. According to the above configuration, it becomes possible to visually and easily grasp, using the marker, what actions the person being monitored performed and when.

[0011] Furthermore, in the above-mentioned monitoring system, it is more preferable if the output device displays the presence information, which is one of the monitoring item information and indicates whether or not the monitored person is present in the room, in a color corresponding to the presence or absence of the person in the room as the background color of the column in the display image. According to the above configuration, it becomes possible to visually and easily grasp whether or not a person to be monitored is present in the room based on the background color.

[0012] Furthermore, in the above monitoring system, it is more preferable that the markers indicating the monitoring item information are color-coded for each piece of monitoring item information using a color that is displayed based on the value of the monitoring item information. According to the above configuration, it is possible to visually and easily grasp the state of each action of the person being monitored for each monitoring item.

[0013] In the above monitoring system, it is more preferable that the markers are rectangular, and each piece of behavioral information of the monitored person is displayed on the time axis by a marker having a width corresponding to the duration of the behavior. According to the above configuration, it is possible to visually and easily grasp not only when the monitored person performed a movement but also the state of each movement.

[0014] In the above monitoring system, it is more preferable that the measuring instrument includes a plurality of sensors arranged at different positions in the room, each of which measures a corresponding monitoring item. According to the above configuration, it is possible to measure each of a plurality of monitoring items of a person to be monitored. [Effects of the Invention]

[0015] According to the monitoring system of the present invention, by displaying on the screen a display image including monitoring item information for each of a plurality of monitoring items, it is easy to visually grasp the physical condition of the person being monitored. [Brief explanation of the drawings]

[0016] [Figure 1] 1 is a schematic diagram illustrating a first example of a monitoring system according to an embodiment of the present invention. [Figure 2] 1 is a schematic diagram showing an example of displaying monitoring item information in a first example of a monitoring system according to an embodiment of the present invention; [Figure 3] FIG. 2 is a schematic diagram showing a second example of a monitoring system according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] <<Regarding a monitoring system according to one embodiment of the present invention>> Hereinafter, one embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to the accompanying drawings. In the drawings, each component is shown somewhat simplified and schematic to make the explanation easier to understand, and the size (dimensions) of each component and the spacing between components shown in the drawings may differ from the actual ones.

[0018] In the following explanation, the monitoring system will be described using a monitoring target person present in a room in a building such as a house as an example. However, the present invention is not particularly limited to a specific building structure as long as it is a room, and can also be applied to buildings other than houses, such as rooms in hospitals and nursing homes. Furthermore, in the monitoring system, the person to be monitored is not particularly limited in terms of gender, age, etc. Furthermore, the health condition of the person to be monitored is not particularly limited either, and the person to be monitored may be a sick person, an injured person, a person undergoing rehabilitation, a person under observation, a person requiring nursing care, or a person requiring care.

[0019] FIG. 1 is a schematic diagram showing a first example of a monitoring system according to an embodiment of the present invention. The monitoring system 10 shown in FIG. 1 monitors a monitoring target H who is present in a room 11a of a room 11, and includes an output device 12. The room 11 is a space where the person to be monitored H lives, but is not particularly limited thereto, and may be a room in one's own home, a room in a care facility, or a room in a hospital. The monitoring system 10 is provided in a room 11a with a bed 13, a toilet 14, and a door 15. Although not shown, a mattress, futon, or the like is laid on the bed 13. Although not shown, lighting is provided on the ceiling in the room 11. Although not shown, the room 11 is also provided with windows that allow light in and curtains that can adjust the amount of light coming in from the windows. By opening and closing the door 15, the person to be monitored H can enter and exit the room 11. The size of the room 11 is not particularly limited.

[0020] A measuring instrument 16 for measuring a plurality of monitoring items in the room 11a is provided in the room 11a of the room 11. The measuring instrument 16 outputs signals according to the measurement results of the plurality of monitoring items. The measuring instrument 16 includes a plurality of sensors arranged at different positions in the room 11a, and each sensor measures a corresponding monitoring item. The measuring instrument 16 has various sensors corresponding to the monitoring items. The type of sensor is not particularly limited as long as it measures the monitoring item, and a sensor corresponding to the monitoring item is used as appropriate. Measurements by the measuring instrument 16 also include human detection using the human presence sensor 16c described below. Measurements by the measuring instrument 16 include "the presence or absence of a person" and "whether a human body has passed through a specified location." The number of sensors is also not particularly limited, and a number of sensors corresponding to the monitoring items is used as appropriate.

[0021] The monitored items are the behavior of the monitored person H in the room 11a and the biological information of the monitored person H. Specifically, the monitored items include, but are not limited to, the below-described "turning over in bed," "sitting up," "standing up," "walking speed," and "blood pressure." Other monitored items include, for example, walking distance, time spent in front of the door, number of times the door is opened and closed, number of times moving from the bed to the toilet, pulse rate, respiratory rate, and body temperature. Among the monitoring items, items related to the behavior of the monitored person H are called behavior items. The behavior items include, for example, turning over in bed, getting up, standing up, walking, walking speed, walking distance, time spent in front of the door, number of times the door is opened and closed, and number of times the person moves from the bed to the toilet. The behavior items correspond to the behavior information described below.

[0022] As the measuring device 16, for example, a millimeter wave sensor 16a is provided in the room 11a. This makes it possible to measure the blood pressure of the person being monitored H. The millimeter wave sensor 16a can also identify the position of the person being monitored H in the room 11a. The millimeter wave sensor 16a can also measure the walking speed of the person being monitored H. This makes it possible to measure the position of the person being monitored H in the room 11a and the time that the person being monitored H stays at that position. The millimeter-wave sensor 16a uses millimeter waves to measure small movements of 0.1 to 0.5 millimeters that the heart exerts on the surface of the human body due to heart movement, and obtains the cardiac cycle or contraction time. The millimeter-wave sensor 16a then analyzes the data obtained by the millimeter waves, such as the cardiac cycle or contraction time, to obtain the systolic blood pressure and mean blood pressure.

[0023] Furthermore, a biological information sensor 16b is provided under the mattress (not shown) of the bed 13. The biological information sensor 16b measures the pulse rate and respiratory rate of the monitoring target person H lying on the bed 13, as well as body movements such as turning over in bed, the time when the monitoring target person H gets up from the bed 13, and the time when the monitoring target person H gets out of the bed 13. The biological information sensor 16b is in the form of a sheet, and a known sensor used in nursing care can be used. Since the biological information sensor 16b measures the monitoring target person H while he is lying on the mattress, it does not interfere with his daily life. Furthermore, a human presence sensor 16c is provided in the toilet 14. This makes it possible to identify whether or not the person to be monitored H is present in the toilet 14, and to measure the length of time the person to be monitored H has been in the toilet 14.

[0024] An opening / closing sensor 16d is provided on the door 15. The opening / closing sensor 16d can determine whether the door 15 is open or closed. Meanwhile, as described above, the millimeter-wave sensor 16a can determine the position of the monitored person H in the room 11a, and therefore the millimeter-wave sensor 16a can determine whether the monitored person H has moved from the bed 13 to in front of the door 15. For this reason, for example, if the millimeter-wave sensor 16a determines that the monitored person H has moved from the bed 13 to in front of the door 15, the opening / closing sensor 16d detects that the door 15 has opened, and the millimeter-wave sensor 16a determines that the monitored person H is not in front of the door 15 after a predetermined time has elapsed, it is determined that the monitored person H has left the room 11. On the other hand, when the millimeter wave sensor 16a has determined that the monitored person H is not in front of the door 15, the opening of the door 15 is detected by the opening sensor 16d, and after a predetermined time has elapsed, the millimeter wave sensor 16a has determined that the monitored person H has moved from the door 15 toward the bed 13, it is determined that the monitored person H has entered the room 11. By combining the opening and closing sensor 16d and the millimeter wave sensor 16a in this way, it is possible to determine whether the monitored person H is present in the room, and also to determine the time the monitored person H is present in the room and the time the monitored person H is outside the room 11.

[0025] The measuring instrument 16 outputs signals corresponding to the measurement results of a plurality of monitoring items to the receiving unit 20 of the output device 12 via wired, wireless, or communication, or via the Internet. When a signal is output to the output device 12 wirelessly, a transmitter (not shown) is provided for each of the sensors of the measuring instrument 16, and the signal is output from the transmitter to the receiver 20 of the output device 12. The sensing interval of the measuring instrument 16 is not particularly limited, but is determined appropriately depending on whether it is necessary to frequently check the condition of the person being monitored H, the processing capabilities of the various sensors of the measuring instrument, and the information processing capabilities of the output device 12. Furthermore, the sensing interval of the measuring instrument 16 may be changed depending on the time of day.

[0026] The output device 12 outputs monitoring item information corresponding to the measurement results of the plurality of monitoring items based on signals corresponding to the measurement results of the plurality of monitoring items by the measuring instrument 16 . The output device 12 has a receiving unit 20, a processing unit 22, a memory 24 (storage unit), and a control unit 26, and further has a display unit 27 and an input unit 28. The receiving unit 20, the processing unit 22, and the memory 24 are controlled by the control unit 26. The output device 12 is a device into which a signal corresponding to the measurement results of a plurality of monitoring items by the measuring instrument 16 is input to the receiving unit 20. The output device 12 does not need to be adjacent to the room 11, and may be located in a building separate from the building in which the room 11 is located, or in a remote location, as long as the receiving unit 20 can receive signals corresponding to the measurement results of a plurality of monitoring items by the measuring instrument 16. For example, the output device 12 may be located in a remote location, such as in a different city or town from the room 11.

[0027] The receiving unit 20 receives signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16. The receiving unit 20 also records the time at which the signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16 are received. The receiving unit 20 is configured to receive signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16 via wired, wireless, communication, or internet output. If the output is wired, the receiving unit 20 receives the signals. If the output is wireless or via communication, the receiving unit 20 has a converter that receives radio waves containing information from the transmitted signals and converts them into signals. If the output is via the internet, the receiving unit 20 is connected to the internet, which allows the receiving unit 20 to receive signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16. Furthermore, in the case of internet output, as described above, the signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16 may be output to a server on the cloud, and then the receiving unit 20 may access the server on the cloud to receive the signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16. The signal corresponding to the measurement results of the plurality of monitoring items by the measuring instrument 16 received by the receiving unit 20 and the time of reception may be stored in the memory 24 .

[0028] The processing unit 22 obtains monitoring item information corresponding to the measurement results from signals corresponding to the measurement results of a plurality of monitoring items by the measuring instrument 16. Specifically, the blood pressure of the monitoring target H and the walking speed of the monitoring target H can be obtained from the signal of the millimeter-wave sensor 16a. In addition, the position of the monitoring target H in the room 11a and the time spent at that position can be measured from the signal of the millimeter-wave sensor 16a. From the signal of the biological information sensor 16b, the pulse rate and respiratory rate of the monitoring target person H lying in bed 13, as well as the time when he / she got up from bed 13 and the time when he / she left bed 13 can be obtained. From the signal of the human sensor 16c, whether or not the person to be monitored H is present in the toilet 14 and the time spent by the person to be monitored H in the toilet 14 can be obtained. From the signal of the open / close sensor 16d, whether or not the person to be monitored H is present in the room, the time the person to be monitored H is present in the room, and the time the person to be monitored H is outside the room 11 can be obtained. Among the monitoring item information, information relating to the behavior of the monitored person H is called behavior information. Among the monitoring item information, behavior information relating to the behavior of the monitored person H includes turning over in bed, getting up, standing up, walking, walking speed, time spent in front of the door, number of times the door is opened and closed, number of times moving from the bed to the toilet, etc.

[0029] The processing unit 22 performs signal processing according to signals from the various sensors of the measuring instrument 16 to obtain multiple pieces of monitoring item information for the monitoring target H. Furthermore, the multiple pieces of monitoring item information for the monitoring target H are stored in the memory 24, for example, for each monitoring target H. This allows the multiple pieces of monitoring item information for the monitoring target H to be organized into a database, which is stored in the memory 24 as a library. The output device 12 (processing unit 22) causes the display unit 27 to display a display image including multiple pieces of monitoring item information of the monitoring target H stored as a library from the memory 24. At this time, the output device 12 (processing unit 22) causes the screen (not shown) of the display unit 27 to display a display image including monitoring item information for each of the multiple monitoring items of the monitoring target H. Note that the method for displaying the monitoring item information in the display image is not particularly limited, and for example, it may be displayed as in a display image 30 shown in FIG. 2, which will be described later.

[0030] As a display format for displaying the display image including the monitoring item information for each of the multiple monitoring items on the screen, it is preferable that the display image be displayed on the same screen, in order to make it easier to grasp the monitoring items. Here, "the same screen" means that it is displayed on one display. Display in one display area (window) within one display also corresponds to "display on the same screen." Display in each of multiple display areas within one display also corresponds to "display on the same screen." In addition, when there are multiple displays, display on each of the multiple displays also corresponds to "display on the same screen," and when multiple displays are combined into one display, display images including monitoring item information displayed on the multiple displays also corresponds to "display on the same screen." The display unit 27 is not limited to displaying a display image including monitoring item information for each of the above-mentioned multiple monitoring items, but also displays information that is displayed on a general personal computer, such as information input to the output device 12.

[0031] As described above, the memory 24 stores signals corresponding to the measurement results of multiple monitoring items by the measuring instrument 16 and the time of reception. It also stores multiple monitoring item information for the monitoring subject H. As a result, as described above, the multiple monitoring item information for the monitoring subject H is compiled into a database and stored in the memory 24 as a library. In addition to this, for example, average values ​​by age and average values ​​by gender for each monitoring item may also be stored. Furthermore, the memory 24 also stores various information used by the processing unit 22, such as signal processing algorithms corresponding to signals from various sensors. The memory 24 also stores color information set depending on whether or not a person is present in the room, as described below. The configuration of memory 24 is not particularly limited as long as it is capable of storing the above-mentioned data, and may be configured to include various storage media such as DRAM (Dynamic Random Access Memory), HDD (Hard Disk Drive), and SSD (Solid State Drive).

[0032] The display unit 27 displays, for example, a display image including monitoring item information, and various known displays are used. The number of displays is not particularly limited, and may be one or more, or may be a so-called multi-display. The display unit 27 also includes a device such as a printer for displaying various information on an output medium. The input unit 28 is an input device such as a mouse and a keyboard for inputting various information according to instructions from an operator. A smartphone can also be used as the input unit 28. In this case, an application that functions as a keyboard or the like can be installed in the smartphone.

[0033] The output device 12 executes a program (computer software) stored in a storage medium such as a ROM using the control unit 26, thereby functionally forming the processing unit 22. As described above, the output device 12 may be configured by a computer in which each part functions as a result of the program being executed, or may be a dedicated device in which each part is configured with a dedicated circuit, or may be configured by a server to be executed on the cloud.

[0034] Next, a specific example of the display of monitoring item information will be described. The output device 12 (processing unit 22) preferably displays multiple pieces of behavioral information related to the behavior of the monitored person among the monitoring item information using a common time axis, which allows the user to visually and easily grasp the behavior of the monitored person over time. Furthermore, it is preferable that the output device 12 (processing unit 22) provide a column for each monitoring item information in the display image and display a marker indicating the monitoring item information in each column. This makes it easy to visually grasp what behavior the monitored person performed and when using the marker. Furthermore, it is preferable that the markers are rectangular, and each piece of activity information of the monitored person is displayed on the time axis by a marker with a width corresponding to the duration of the activity, which makes it easy to visually grasp not only when the monitored person performed the activity but also the status of each activity.

[0035] Fig. 2 is a schematic diagram showing an example of the display of monitoring item information in a first example of a monitoring system according to an embodiment of the present invention. Fig. 2 shows a state in which a display image 30 showing multiple pieces of monitoring item information for monitoring target person H, as described above, is displayed on the screen (not shown) of display unit 27. Display image 30 may be a still image or a moving image, and is not particularly limited, and may be one in which the monitoring item information is updated and displayed.

[0036] FIG. 2 shows an example in which "turning over," "sitting up," "standing up," "walking speed," and "blood pressure" are set as multiple monitoring items. The display image 30 shown in FIG. 2 shows "turning over," "sitting up," "standing up," "walking speed," and "blood pressure" as multiple pieces of monitoring item information corresponding to the multiple monitoring items. Of these, "turning over," "sitting up," "standing up," and "walking speed" are multiple pieces of behavioral information related to the behavior of the person being monitored. "Blood pressure" is biological information of the person being monitored. The display image 30 has a column for each monitoring item information, and for example, a column 31a for "turning over," a column 31b for "sitting up," a column 31c for "standing up," a column 31c for "walking speed," and a column 31e for "blood pressure" are arranged in parallel. In addition, a time axis 32 common to columns 31a to 31e is displayed next to column 31a. When multiple pieces of behavioral information related to the behavior of the person being monitored H are displayed using the common time axis 32, it is easy to visually grasp what behavior the person being monitored H has performed over time. It is preferable that the output device 12 displays markers 33 indicating the monitoring item information in each of the columns 31a to 31e. This makes it easy to visually understand what behavior the monitoring target person H performed and when, based on the display position of the markers 33.

[0037] In the display image 30 shown in FIG. 2, for example, the marker 33 in the "turning over" column 31a indicates that the monitored person H is turning over in his / her sleep. Here, the marker 33 is, for example, rectangular, and the width d1 of the marker 33 on the time axis 32 indicates the time spent tossing and turning. A wider marker 33 indicates a longer time spent tossing and turning, and the width of the marker 33 can be used to visually grasp the time spent tossing and turning. Similar to "tossing and turning," other items such as "sitting up," "standing up," "walking speed," and "blood pressure" can also be visually grasped from the marker 33 and the width of the marker 33. For example, the width d2 of the "standing up" marker 33 is wider than the width d1 of the "turning over" marker 33, and it is easy to visually understand that the behavior time of "standing up" is longer than that of "turning over."

[0038] In addition, in the output device 12, among the monitoring item information, the presence information indicating whether or not the monitored person H is present in the room is set in a color corresponding to whether or not the monitored person H is present in the room, and the color information set in the presence information according to whether or not the monitored person H is present in the room is stored in memory 24. Since it is possible to visually easily grasp whether or not the person to be monitored H is present in the room, it is preferable that the background color of the fields 31a to 31e be displayed in a color corresponding to the presence or absence of the person to be monitored H in the display image. For example, in the fields 31a to 31e, the background color of the area 34 from midnight to 11:00 is gray, and the background color of the area 35 from 11:00 to 15:00 is transparent. Therefore, it is visually easy to grasp that the person to be monitored H was present in the room 11 from midnight to 11:00, but was outside the room 11 from 11:00 to 15:00.

[0039] Furthermore, the markers 33 indicating the monitoring item information are preferably color-coded based on the value of the monitoring item information for each monitoring item. This allows the status of each behavior of the monitoring subject to be visually and easily grasped for each monitoring item, and, for example, the risk status of the monitoring subject H for each monitoring item to be visually and easily grasped. In this case, a color corresponding to the value of each monitoring item is preset for each monitoring item, and the value and color of the monitoring item information are stored in the memory 24. When outputting the monitoring item information, the processing unit 22 refers to the memory 24 and determines the color corresponding to the value of the monitoring item information for each monitoring item. The color of the markers 33 is set to the determined color and displayed. The color of the markers 33 is not particularly limited as long as it can identify the value of the monitoring item information. However, it is preferable to use a common color for each monitoring item, such as a color indicating a high value or a color indicating a low value. This allows the value of the monitoring item information to be visually and easily grasped based on the color of the markers 33.

[0040] For example, in Figure 2, the color of the marker 33 is displayed by the pattern of the marker 33. A marker 33 with no pattern is blue, a hatched marker 33 is yellow, and a cross-hatched marker 33 is red. For example, for "standing up," the marker 33 is color-coded, for example, blue, yellow, or red, depending on the time required to stand up. Blue indicates that the time is within the set time, yellow indicates that the time has exceeded the set time but is within the allowable range, and red indicates that the time has exceeded the allowable range. Similarly, for "blood pressure," the marker 33 is color-coded, for example, blue, yellow, or red, depending on the value of systolic blood pressure. Blue indicates that the systolic blood pressure value is within the normal range, yellow indicates that the systolic blood pressure value exceeds the normal range but is within the allowable range, and red indicates that the systolic blood pressure value exceeds the allowable range. In this way, by color-coding the marker 33 with colors displayed based on the values ​​of the monitoring item information, it is possible to visually easily grasp the state of each standing up action, in addition to knowing when the above-mentioned standing up action occurred.

[0041] As with "standing up," other actions such as "rolling over," "sitting up," and "walking speed" can be visually and easily grasped, using marker 33 and the color of marker 33, not only when the action was performed but also the status of each action. For example, the risk and other status of monitored person H can be visually and easily grasped for each monitoring item. Regarding "blood pressure," the time of blood pressure measurement can be determined from the position of the marker 33, and the state of blood pressure can be determined from the color of the marker 33, so the state of blood pressure, such as when blood pressure is high, can be easily visually determined.

[0042] Furthermore, by displaying a display image containing monitoring item information for each of a plurality of monitoring items on the screen, it is easy to visually grasp the physical condition of the person being monitored, and in the display image 30 of Fig. 2, for example, it can be seen that in time period Q1 from 3 o'clock, the person being monitored H is standing up and walking fast, which makes it possible to infer, for example, that walking assistance is required. Also, for example, during the time period Q2 starting at 7 o'clock, the blood pressure of the monitored person H is high, and there is a possibility that he has early morning hypertension. Furthermore, for example, during the time period Q3 from 9 pm, it is estimated that the monitored person H turns over a lot in his / her sleep and that his / her daytime activity level is insufficient. In this way, the state of the monitored person H can be easily grasped.

[0043] Furthermore, by displaying a display image containing monitoring item information for each of a plurality of monitoring items on the screen, it is easy to visually grasp the physical condition of the person being monitored, making it easier to understand their behavioral patterns and provide nursing care or care at the appropriate time.It is also easy for the person being monitored to understand their own behavior. Furthermore, if the behavioral patterns are the same or similar, the same response can be given regardless of the person being monitored, thereby making the work of nurses or caregivers more efficient.

[0044] <<Other embodiments>> Fig. 3 is a schematic diagram showing a second example of a monitoring system according to an embodiment of the present invention. In Fig. 3, the same components as those shown in Fig. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted. The monitoring system 10a shown in Fig. 3 differs from the monitoring system 10 shown in Fig. 1 in that it targets a building 19 with multiple rooms 11, that there is one monitored person H (see Fig. 1) in each room 11, and that the display unit 27 has multiple display areas 40 on one screen, and displays display images 30 corresponding to the number of monitored people H. Other configurations are the same as those of the monitoring system 10 shown in Fig. 1.

[0045] 3, there are eight rooms 11, eight monitoring targets H, eight display areas 40 on one screen of the display unit 27, and a display image 30 for each monitoring target H is displayed in each of the eight display areas 40. In other words, eight display areas 40 are simultaneously provided on the same screen. In this way, the monitoring target H is not limited to one person, but can be multiple, and by displaying a display image including each monitoring item information of multiple monitoring targets H on one screen, it is possible to visually and easily grasp what actions each monitoring target H took at the same time and what actions they took in chronological order. In addition to when an action was taken, the status of each action can be visually and easily grasped. Furthermore, it is easy to visually know whether each person to be monitored H is present in the room.

[0046] Although an embodiment of the monitoring system of the present invention has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and does not limit the present invention. In other words, the present invention can be modified and improved without departing from the spirit of the present invention. Furthermore, it goes without saying that the present invention includes equivalents thereof. [Explanation of symbols]
