[System overview]
FIG. 1 is an image diagram for explaining a schematic configuration of a heat stroke risk management system equipped with the physical condition evaluation system described in the present embodiment.

Further, FIG. 2 is a block diagram showing a configuration example of each part of the heat stroke risk management system equipped with the physical condition evaluation system according to the present embodiment.

As shown in FIG. 1, a worker 10 (evaluated person) who is a managed person working at a construction site is a biological information acquisition unit that acquires biological information such as body temperature (body surface temperature), heart rate, and sweating amount. The data chip 11 is attached to the chest and possesses a smartphone 12 as a portable terminal that functions as a biometric information transmitting unit 13 that transmits the biometric information obtained by the data chip 11 to the outside.

In the heat stroke risk management system described in the present embodiment, the data chip 11 for acquiring the biological information of the worker 10 is attached to the chest of the undershirt worn by the worker 10.

FIG. 3 is a diagram showing a configuration example of an undershirt worn by an operator in the heat stroke risk management system according to the present embodiment. FIG. 3A shows the front surface of the undershirt to which the biological information acquisition unit is attached, and FIG. 3B shows the back surface of the undershirt.

As shown in FIG. 3, a data chip 11 is arranged on the chest of the undershirt 18 worn by the worker 10 in the heat stroke risk management system according to the present embodiment. More specifically, the data chip 11 is connected to a data acquisition transmission unit 11a arranged in the central portion of the chest of the surface 18a of the undershirt 18 and the data acquisition transmission unit 11a, and is connected to the back surface 18b of the undershirt 18. That is, it is composed of an electrode portion 11b extending in the left-right direction on the portion in contact with the skin.

In the heat stroke risk management system described in the present embodiment, as a method of acquiring the biometric information of the worker 10 with the data chip 11 arranged on the chest, a method of fixing the data chip 11 to the undershirt 18 shown in FIG. Not limited to. For example, a method in which the data chip 11 is placed in a highly adhesive sheet-shaped mounting cover and directly attached to the chest, or a work using an elastic mounting belt capable of holding the data chip 11 in close contact with the body. It is possible to adopt a method of placing it on the chest of a person. However, in the method using the mounting cover or the mounting belt, the discomfort felt by the worker 10 by mounting the data chip 11 cannot be eliminated, and when the data chip 11 is worn for a long time, the data chip 11 is caused by sweat or the like. There is a risk that it will come off the surface of the body or the mounting position will shift.

On the other hand, according to the method of fixing the data chip 11 to the undershirt 18 worn by the worker 10 as shown in FIG. 3, it is special to the fact that the data chip 11 is attached to the worker 10. Biological information can be acquired without making people aware of it. Further, even if the worker 10 sweats or the body is twisted during the work, the data chip 11 fixed to the undershirt 18 does not completely come off from the body surface of the worker 10. Even if the electrode portion 11b is temporarily separated from the chest surface of the worker 10, it can immediately return to the original state and maintain a state in which the mounting position does not substantially change.

Further, by arranging a sensor that detects acceleration in two or three directions on the data chip 11 that acquires the biological information of the worker 10, acceleration data indicating the movement of the body of the worker 10 is detected in three dimensions. It can be used as a three-dimensional acceleration sensor. As a result, the intensity of the work operation performed by the worker 10 can be acquired as acceleration data. Further, when the posture of the worker 10 suddenly changes, such as when the worker 10 falls down, the movement of the body can be detected by the data chip 11.

When the data chip 11 is used as the biological information acquisition unit for acquiring the biological information of the worker 10, the data chip 11 is arranged in the waist, back, and upper arm of the worker in addition to the chest of the worker described above. , It is possible to adopt a form arranged on the wrist or leg. Even in these cases, as a method of closely fixing the data chip 11 to the body surface of the worker, in addition to the method of arranging the data chip on the inner surface of the underwear, the data chip is fixed by using a mounting cover or a mounting belt. Can be adopted. However, it is necessary to detect heartbeat data as biometric information, and in order to accurately detect the movement of the entire body as the movement of the body of the worker 10, it is close to the trunk of the worker and the upper body. Since it is preferable to acquire acceleration data, it is preferable to place the data chip 11 on the chest of the operator 10, and it is most preferable to use the undershirt 18 as shown in FIG.

The data chip 11 and the smartphone 12 possessed by the worker 11 are always connected by short-distance communication such as Bluetooth (registered trademark), and the biometric information of the worker 10 acquired by the data chip 11 can be obtained at any time. It is sent to the smartphone 12. Further, if it is possible to connect with a signal line having a thickness that does not give a sense of discomfort to the worker 10, the data chip 11 and the smartphone 12 may be connected by wire.

The smartphone 12 is always connected to the Internet 20 as a network environment by using its own data receiving unit 15 and data transmitting unit 16 using a wireless LAN or an information carrier of a mobile phone. Then, the smartphone 12 transmits the biometric information of the worker 10 to the cloud server 21, which is a server provided with the data processing unit 22 installed on the Internet 20. Further, the smartphone 12 includes an image display unit 17 as a display unit for displaying the physical condition evaluation result of the evaluated person 10 evaluated by the physical condition evaluation system.

The cloud server 21 internally includes a data receiving unit 23 and a data transmitting unit 26, can exchange information via the Internet 20, and also includes a data processing unit 22, and has a plurality of workers. It receives biometric information, determines the risk of developing heat stroke for each worker, and creates warning information to warn the worker if the risk of developing heat stroke is increasing. Further, the cloud server 21 includes a data recording unit 24, and can record biometric information, warning information creation history, and the like of each of a plurality of workers in chronological order.

Further, the cloud server 21 has a weather information acquisition unit 25, acquires weather information (25) from an information site that provides weather information via the Internet 20, and is an area where the worker 10 is working. It is possible to obtain weather conditions at the current time such as temperature, humidity, and amount of sunshine, and weather forecasts that anticipate changes within the next few hours.

Further, the cloud server 21 is a personal computer 31 as an administrator information terminal used by the site supervisor 30, who is the administrator who supervises the work of the worker 10 whose risk of heat stroke is determined at the construction site, via the Internet 20. Is connected to. Therefore, the site supervisor 30 at the work site of the worker 10 determines whether or not the biometric information of the worker 10 and the warning information transmitted from the cloud server 21 at any time are generated by the data receiving unit 33 of the personal computer 31. Can be grasped.

The data processing unit 22 of the cloud server 21 functions as a risk determination unit for determining the risk of the worker 10 developing heat stroke based on changes in biological information. As an example of the determination, the data processing unit 22 generates a threshold value for determining whether or not the risk of developing heat stroke has increased based on the resting data, which is the biometric information of the worker 10 at rest, and is working. By comparing the working data, which is biometric information, with the threshold value, the risk of developing heat stroke of the worker 10 can be determined.

Further, in the heat stroke risk management system according to the present embodiment, the data processing unit 22 of the cloud server 21 functions to calculate an index used for evaluation in the physical condition evaluation system. Therefore, the data processing unit 22 acquires the heartbeat data and the acceleration data of the evaluated person acquired by the data chip 11 via the biological information transmission unit 13 of the mobile terminal 12, and evaluates the physical condition in the physical condition evaluation system. Calculate the reference heart rate value and the heart rate response value as the reference. As will be described later, when the physical condition evaluation value is used as an index for evaluating the physical condition of the evaluated person, the data processing unit 22 calculates the physical condition evaluation value based on the reference heart rate value and the heart rate response value. conduct.

Further, the cloud server 21 includes past history information of the determination target worker 10 recorded in the data recording unit 24, weather information of the work area acquired by the weather information acquisition unit 25, and further, the determination target worker. Based on environmental information such as changes in biological information of workers other than the worker to be judged who are working at the same site as the above, the judgment result of the heat stroke onset risk of the worker 10 is corrected to be more realistic. Can be assumed to be. Further, in the physical condition evaluation system, the data processing unit 22 that functions as an index calculation unit based on the past evaluation results of the evaluated person recorded in the data recording unit 24 more accurately determines the reference heart rate value of the evaluated person. And the heart rate response value can be calculated.

In the heat stroke onset risk management system equipped with the physical condition evaluation system described in the present embodiment, the data processing unit 22 is not limited to the cloud server 21. For example, various functions of the cloud server 21 including the data processing unit 22 may be mounted on the administrator information terminal 31 or the management computer 41 of the business establishment. The device does not matter.

Whether or not the personal computer 31 of the site supervisor 30 (administrator) as the administrator information terminal has generated biometric information and warning information about the workers belonging to the work site supervised by the site supervisor 30 including the worker 10. It is provided with an information management unit 32 that manages the information. The information management unit 32 always keeps track of the heat stroke onset risk information as to whether or not the biometric information and warning information of each worker are generated based on the information transmitted from the cloud server 21. Further, the information management unit 32 outputs the acquired heat stroke onset risk information and other environmental information of each worker to the display image processing unit 35, and the display image processing unit 35 outputs the acquired information to the display device 36 such as a liquid crystal monitor. The displayed screen content is adjusted. In this way, the on-site supervisor 30 can see the biometric information of the worker 10 working at the work site he supervises, the risk of developing heat stroke, etc. as a whole centrally or on a screen that is easy to see as detailed information of each worker. Can be grasped.

Further, the information management unit grasps the physical condition evaluation result of each worker 10 calculated by 32 and the data processing unit 22 as a reference heart rate value, a heart rate response value, and / or a physical condition evaluation value, and displays image processing unit. The physical condition evaluation result can be displayed on the display device 36 which is a display unit via the 35.

As shown in FIG. 1, when the personal computer used by the on-site supervisor is a desktop type, the display device 36 is a separate body from the personal computer main body. As described above, the administrator information terminal 31 having the information management unit 32 and the like and the display device 36 for displaying the screen for the administrator are not limited to being physically integrated. Further, for example, when the data is confirmed by a plurality of people, it is conceivable to use a dedicated large-sized image display device or to enlarge and project the displayed image on a screen, a wall surface, or the like by a projector.

Further, on the personal computer 31 of the on-site supervisor 30, the worker 10 prevents the onset of heat stroke by receiving the biological information of the worker 10 after notifying the warning information and the confirmation of receipt of the warning information from the worker 10. It is possible to confirm whether or not measures have been taken to prevent heat stroke, and if the worker 10 has not taken measures to prevent the onset of heat stroke, the warning information is repeatedly transmitted to the target worker 10. It is possible to call the worker 10's attention.

In the above description, an example in which the data processing unit 22 of the cloud server 21 generates warning information notifying the worker 10 that the risk of developing heat stroke is high has been described. It can be generated by the information management unit 32 installed in the personal computer 31 of the site supervisor 30. Further, both the data processing unit 22 and the information management unit 32 can be set to generate warning information. By doing so, the personal computer 31 of the site supervisor 30 who actually supervises the work site generates warning information prior to the determination result in the data processing unit 22 and transmits it to the symmetrical worker 10. Therefore, it may be possible to further reduce the risk of developing heat stroke depending on the actual situation at the work site.

The warning information generated by the data processing unit 22 of the cloud server 21 or the personal computer 31 of the on-site supervisor 30 is transmitted from the data transmission unit 34 of the personal computer 31 of the on-site supervisor 30 to an information carrier of a local network such as a wireless LAN or a mobile phone. It is transmitted to the smartphone 12 equipped by the worker 10 via the network including the above. Upon receiving the warning information, the warning notification unit 14 of the smartphone 12 develops heat stroke for the worker 10 by using various information transmission means such as voice, screen display, lighting / blinking of the lamp, and vibration. Notify that the risk of doing so is increasing. The worker 10 who has confirmed the warning information reports that the warning information has been received through the touch panel of the smartphone 12 or an operation button, and takes measures such as interrupting the work and taking a rest.

The smartphone 12 of the worker 10 confirms the warning information and transmits the interruption of the work to the personal computer 31 of the supervisor 30, and the supervisor 30 confirms that the worker 10 has taken measures. can.

Further, in the heat stroke risk management system described in the present embodiment, the heat stroke onset risk data at the work site grasped by the site supervisor 30 is transmitted to the smartphone 12 of the worker 10, and the worker 10 receives the heat stroke risk data. You can check the current risk of heat stroke at the work site where you work. For example, if it can be confirmed that the risk of heat stroke of workers other than oneself is high, each worker can take measures against heat stroke by himself / herself. In addition, if it is found that there is another worker who has received the warning information of the risk of developing heat stroke and interrupted the work, the worker 10 to whom the warning information has been transmitted from the site supervisor 30 responds to the warning information more obediently. Can be expected.

Further, on the smartphone 12 owned by the worker 10, the change in the risk of developing heat stroke of the worker 10 up to now, the numerical value of his / her own biometric information acquired by the data chip 11, the calorie consumption calculated from the biometric information, etc. The related information of can be displayed on the screen and can be referred to by the worker 10 himself.

Further, in the heat stroke risk management system of the present embodiment, information on the physical condition of the evaluated person evaluated by the physical condition evaluation system is displayed on the image display unit 17 of the smartphone 12 owned by the worker 10. Therefore, the image display unit 17 displays a display screen for displaying the physical condition evaluation result of the worker 10 as the evaluated person who is the holder of the smartphone 12 and the physical condition evaluation result in an easy-to-understand format for the worker 10. It has an image data creation unit. The physical condition evaluation result displayed on the display screen of the smartphone 12 possessed by the worker 10 will be described in detail later.

The cloud server 21 is also connected to the management computer 41 in the company or business establishment 40 to which the worker 10 belongs via the Internet 20, and the biometric information of the worker 10 transmitted to the personal computer 31 of the site supervisor 30 and the cloud. Various information used by the server 21 to determine the risk of developing heat stroke, and the values of the reference heart rate value and heart rate response value of the worker 10 calculated by the data processing unit 22 are displayed in real time at the business establishment. It is transmitted to the management computer 41 of 40. Since the management computer 41 of the business establishment 40 includes its own data receiving unit 42 and data transmitting unit 43, it is also connected to the personal computer 31 of the site supervisor 30 via the Internet, and the site supervisor 30 to the worker 10 It is possible to confirm information such as whether the warning information is correctly transmitted to the user and whether the worker 10 has taken preventive measures against heat stroke, and give a predetermined instruction as necessary. By doing so, it is possible to confirm the situation of the worker 10 and the response at the work site even at the business office 40 to which the worker 10 belongs, and back up the avoidance of the risk of heat stroke of the worker 10. be able to.

Further, although not explicitly shown in FIG. 1, since the cloud server 21, the personal computer 31 of the site supervisor 30, and the management computer 40 of the office 40 are connected by the Internet 20, the personal computer 31 and the management computer 40 are on the side. It is possible to access the cloud server 21 from the cloud server 21, control the data processing contents in the cloud server 21, update the data processing program in the data processing unit 22, and need for heat stroke risk management from the cloud server 21. Information can be retrieved as appropriate. Further, the physical condition evaluation result of the worker 10 who is the evaluated person, which is evaluated by the physical condition evaluation system installed at the same time, is displayed on the screen of the personal computer 31 of the site supervisor 30 and the management computer 40 of the office 40. Therefore, it is possible to grasp the physical condition evaluation result of each worker.

In the above explanation, a smartphone is exemplified as a mobile terminal equipped by a worker, but the mobile terminal of a worker is not limited to a smartphone, and is specialized in mobile phones, tablet devices, and heat stroke risk management systems. It is possible to use a dedicated small terminal device capable of transmitting / receiving information and displaying the result of physical condition evaluation.

In addition, as the administrator information terminal operated by the on-site supervisor, in addition to the illustrated personal computer, especially the desktop personal computer shown in FIG. 1, information transmission / reception via a network such as a notebook personal computer, a tablet personal computer, and a small server device can be performed. Various information devices capable of displaying and recording data can be adopted.

Further, in the above explanation, the form of transmitting the warning information from the manager information terminal of the site supervisor to the mobile terminal of the worker has been described, but when the warning information is generated by the risk determination unit of the cloud server, the cloud server. The system can also be configured to send warning information directly to the worker's mobile terminal.

When the risk of heat stroke onset of a worker at a construction site is managed by the heat stroke onset risk management system exemplified in this embodiment, the position of the worker to be managed is limited to the construction site. In addition, since the work period extends over a certain number of days, it is possible to construct a wireless LAN at the construction site. In this way, when the person to be managed exists only within a certain range, a unique wireless LAN is constructed, and the biometric information of each worker is transmitted to the manager information terminal of the on-site supervisor via the Internet. It can be done in the LAN without going through. In this case, by connecting to the Internet from the administrator information terminal or from an information device such as a server unit installed in the LAN or another personal computer, the risk of heat stroke in the risk determination section in the cloud server It is possible to make a judgment and use the weather information acquired by the weather information acquisition unit. Further, a risk determination unit for determining the risk of developing heat stroke can be provided in a server unit or a personal computer connected to a LAN at a construction site.

FIG. 4 is a diagram showing a graph for obtaining a reference heart rate value and a heart rate response value from the correlation between the heart rate data and the acceleration data of the evaluated person.

In FIG. 4, the vertical axis represents the heartbeat of the evaluated person, and the unit is (bpm). Further, the horizontal axis represents an acceleration representing the intensity of the movement of the body of the subject, and the unit is (G: gravitational acceleration).

In the physical condition evaluation system according to the present embodiment, the heartbeat of the evaluated person 10 is detected at the timing of the heartbeat of the evaluated person 10 by the electrode portion 11b arranged on the back surface 18b of the undershirt 18 worn by the evaluated person 10. It is detected as a heartbeat waveform which is a change in voltage at the electrode portion 11b. The peak number per minute of this heart rate waveform is the heart rate (bpm) of the evaluated person 10. The heart rate is not limited to the method of counting the peak number of the heart rate waveform for one minute as it is. For example, the number of peaks in a period shorter than 1 minute such as 15 seconds, 20 seconds, 30 seconds, or a period longer than 1 minute such as 2 minutes or 3 minutes is counted and converted into a heart rate per minute. It can be obtained as the heart rate (bpm) per unit time (1 minute) by using various methods such as adopting the method.

Further, particularly when the movement of the evaluated person 10 is intense, not all heartbeat waveforms within a predetermined measurement period can be detected by the electrode portion 11b of the data chip 11, so one heartbeat waveform and the next one. It is also possible to adopt a method of calculating the heart rate per minute from the time difference between the peaks and the heart rate waveform detected in. When the heart rate is obtained from the peak interval of the heart rate waveform in this way, the calculated heart rate is extremely small if the heart rate waveform corresponding to the continuous heart rate is not detected. Therefore, the electrode portion 11b is based on the characteristic of the pulse of the human body that the numerical value is about 70 to 110, and that the numerical value does not change by 20 to 30% or more within a few seconds. It is preferable to determine the certainty of the heart rate obtained from the interval of the obtained heart rate waveforms, and if the data is inaccurate, perform a sifting process such that the data does not work.

Further, if the ratio of the number of cases determined to be inaccurate data as a result of the above sieving in a predetermined period such as 1 minute exceeds the threshold set as 50% as an example, the data It is determined that an abnormality has occurred in the attachment of the chip 11, and the evaluated person is confirmed whether the data chip 11 is in correct contact with the chest, and the undershirt 18 is corrected in the wearing state. It is possible to confirm whether or not an abnormal situation such as a dead battery of the chip 11 has occurred.

If such a data chip mounting abnormality or battery exhaustion occurs, the heat stroke risk management system will not operate properly, so work will be done directly to the worker 10 or through the on-site supervisor 30. It is preferable to notify the person 10 to that effect and instruct the person 10 to be in a state where the biological information can be correctly acquired.

When the heart rate data is detected by counting the actual pulse signal in a predetermined period, it is necessary to continuously measure the pulse in any of the methods of calculating the pulse rate from the interval between two consecutive pulse signals. In particular, when the movement of the body of the person to be measured is small, the heart rate and the acceleration data described later can be acquired intermittently.

The acceleration data is detected in units of gravity acceleration G as a measured value by a three-dimensional acceleration sensor mounted on, for example, a data acquisition / transmission unit 11a of the data chip 11 worn by the evaluated person.

In the physical condition evaluation system according to the present embodiment, since the body movement of the evaluated person 10 is detected by the three-dimensional acceleration sensor, acceleration data in the x-axis direction, the y-axis direction, and the z-axis direction is output. For these data, after excluding the overall noise component by using a statistical method such as the exponential moving average method, the magnitude of the acceleration in each axial direction for a predetermined period is obtained. After that, the sum of squares for the acceleration values in the three-axis directions is obtained, divided by the number of data to obtain the mean square value of the acceleration, and the acceleration data of the evaluated person is calculated from the square root.

The above statistical processing method of heart rate data and acceleration data is only an example. For example, considering the intensity of the body movement of the evaluated person, the heart rate data and acceleration data obtained from the data chip at any time are used. , Various methods can be adopted that can accurately grasp the heart rate of the evaluated person and the acceleration indicating the movement of the body.

Using the regression line for the correlation between the heart rate data indicating the heart rate of the evaluated person and the acceleration data indicating the movement of the body at the time when the heart rate data is obtained, the reference heart rate is used. Calculate the value and the heart rate response value.

FIG. 4 is a graph showing the correlation between the heart rate data and the acceleration data acquired from the evaluated person in the physical condition evaluation system according to the present embodiment.

As shown in FIG. 4, the heart rate (bpm) and the acceleration (G) obtained from the evaluated person at the same timing are plotted on a graph, and the regression line 51 of the data is obtained based on the plot points. Various statistical processing methods can be used to obtain the regression line. For example, the area of the graph is divided according to the numerical value of acceleration, and the median value of the heart rate and acceleration of each division is obtained. A method of fitting a regression line to the coordinates of the obtained median can be used.

The y-axis section of the regression line thus obtained, that is, the section 52 on the heart rate side represents the reference heart rate value of the evaluated person. This reference heart rate value estimates the evaluator's heart rate when the acceleration is 0, that is, in a resting state. Therefore, the reference heart rate value can be referred to as a resting heart rate, a heart rate index, or the like.

Further, the slope of the regression line 51 indicates the degree of increase in the heart rate of the evaluated person with respect to the intensity of body movement. In the physical condition evaluation system of the present embodiment, in order to eliminate individual differences in the numerical values of the slope of the regression line, the slope αi of the regression line at the time of evaluation of the subject is used as a reference as shown in the following equation (1). The numerical value α divided by the slope α0 of the regression line of the data is used as the heart rate response value of the evaluated person.

Heart rate response value α = αi / α0 (1)
Here, as the reference data α0, the value of the slope of the regression line calculated based on the data of a large number of people, which is called big data, can be used. In addition, when evaluating the change in physical condition of the evaluated person with respect to the normal physical condition, the slope of the regression line obtained from all or part of the past measurement data of the evaluated person is used as the reference data α0. The value of can be used. For example, α0 may be obtained from the acquired data of the evaluated person on the previous day. In this way, the heart rate response value α is data normalized so that the slope αi of the regression line at the time of evaluation of the evaluated person becomes 1 when the slope αi is at the same level as the reference value (α0). Is preferable.

The heart rate response value thus obtained is a value obtained by normalizing the degree of increase in heart rate due to the body movement of the evaluated person at the time of measurement with standardized data, and the heart rate response value is 1.0 or more. If it is large, it indicates that the degree of increase in heart rate with respect to the movement of the body is larger than the standard. Therefore, the heart rate response value can be referred to as a mental ability evaluation value, a physical fitness index, or the like.

In the physical condition evaluation system according to the present embodiment, the physical condition at the time of measurement of the evaluated person is shown by using the reference heart rate value thus obtained and the heart rate response value.

As described above, in order to calculate the reference heart rate value and the heart rate response value, a plurality of combinations of the heart rate data and the acceleration data are required. Therefore, in the physical condition evaluation system according to the present embodiment, the physical condition of the evaluated person is evaluated based on the measurement results in a certain period. Since it is considered that data of several tens of minutes to several hours is required for this fixed period, when the measurement result is displayed on-time, for example, the measurement result is updated every two hours from the display time. You may. In addition, by setting a fixed period, which is a measurement period, to half a day or one day, it is possible to evaluate the tendency of the overall physical condition of the evaluated person. In addition, by shortening the measurement period, for example, in units of 30 minutes, changes in the physical condition of the evaluated person can be checked in detail.

[Display of physical condition evaluation results]
FIG. 5 is a diagram showing an example of a display screen of a smartphone, which is a mobile terminal possessed by the evaluated person, in the physical condition evaluation system according to the present embodiment.

As shown in FIG. 5, the display screen 60 shown as an example has a first display area 61 showing general information, a second display area 62 displaying the physical condition evaluation result of a possessed worker, and additional information. It is composed of three display areas with a third display area 63 for displaying.

At the top of the first display area 81, there is a band-shaped portion on which general information of the smartphone such as the current time, the remaining battery level display, the operation mode display, and the operation display of other resident application software is displayed.

Below this band-shaped portion, there is a display portion that displays basic information in the physical condition evaluation system described in the present embodiment. In the example shown in FIG. 5, the name of the company to which the worker who is the evaluated person belongs and the worker In addition to the unique information related to the evaluated person such as the name of the construction site where the company works, the display of related information such as the weather forecast, the button for displaying the past alert history, the setting change button on the display screen, and the compulsory Various operation buttons such as a button for updating data are arranged in. Although not shown, since the physical condition evaluation system according to this embodiment is installed in the heat stroke onset risk management system, information on the heat stroke onset risk management system, for example, the heat stroke onset risk of the evaluated person. An operation button for switching the display contents can be arranged on the screen that displays the numerical value.

In the central portion of the display screen 60 of the smartphone carried by the worker, a two-dimensional map 70 of the physical condition evaluation result of the worker by the physical condition evaluation system is displayed as a second display area 62. The evaluation contents of the second region will be described in detail later with reference to FIG.

Further, in the lower part of the display screen 60 of the smartphone carried by the worker, as a third display area 63, various information regarding the operation of the physical condition evaluation system, and further, the evaluated person himself / herself before starting the work. Operation buttons for registering the group to which you belong, or changing from the display showing your own information to the screen that displays the status of the entire group to which you belong in the physical condition evaluation system or heat stroke risk management system. Buttons for switching ON / OFF of management in the system by operating at the start of work or at the start of work are arranged.

The display example of the smartphone 12, which is a mobile terminal possessed by the worker 10 who is the evaluated person, shown in FIG. 5 is merely an example, and in particular, the display of the first display area 61 and the third display area 63. The contents are appropriately changed so that necessary information can be displayed to the worker 10 in an easy-to-understand manner. Further, the worker 10 can select and appropriately display related information such as his / her own calorie consumption and the progress of construction. Further, it goes without saying that the display order of the display contents of each area other than the area of the upper strip portion of the first display area 61 shown in FIG. 5 can be appropriately changed in the vertical direction.

FIG. 6 shows an enlarged display content of the second area of the display screen of the mobile terminal owned by the operator.

As shown in FIG. 6, in the physical condition evaluation system of the present embodiment, a two-dimensional map 70 showing the current physical condition of the evaluated person is displayed.

In this two-dimensional map 70, the vertical axis shows the reference heart rate value and the horizontal axis shows the heart rate response value. As an example, the center of the map is the reference heart rate value (= 100) and the heart rate response value (= 1.0), respectively. It is a general standard value of. Here, the general standard value indicates the average value of data of a large number of people divided into large categories such as age and gender, such as the whole of Japanese men in their 40s. The average value of the data of a large number of people can be obtained as an actually measured value based on the actual value of all the actual users of the physical condition evaluation system shown in the present embodiment, which is so-called big data. In addition, data acquired by various methods related to conventional physical condition and health index can be obtained as a calculated value obtained by converting into an evaluation value when the physical condition evaluation system shown in the present embodiment is used.

Further, as shown in FIG. 6, in the two-dimensional map displayed on the mobile terminal of the evaluated person in the physical condition evaluation system according to the present embodiment, the difference from the standard value of the reference heart rate value and the heart rate response value is stepwise. The expressed background image is displayed. Specifically, it is divided into an area 71 determined to be in the "normal" state, an area 72 determined to be in the "slightly careful" state, and an area 73 determined to be in the "attention" state outside the area 72. ing. Moreover, as the current physical condition evaluation result of the evaluated person, a plot 74 showing the position based on the latest (for example, the past 2 hours) reference heart rate value and heart rate response value is displayed. By changing the color of each area of the background image of the two-dimensional map, it is possible to visually appeal the difference from the standard value to the evaluated person. In this case, for example, the "normal" area is colored with a blue or green color, the "slightly careful" is colored with a yellow or orange color, and the "attention" is colored with a reddish color. On the other hand, the difference from the standard value can be displayed in an easy-to-understand manner.

As described above, in the physical condition evaluation system according to the present embodiment, the physical condition evaluation result 74 is shown on the two-dimensional map 70 displaying the background images 71 to 73 that gradually express the difference from the standard value. The evaluated person can easily confirm whether the current physical condition is "normal", "slightly careful", or "attention". Further, in the case shown in FIG. 6, since it can be grasped at a glance that both the reference heart rate value and the heart rate response value are higher than the standard value, the boundary portion between the "slightly careful" and "attention" states of one's own physical condition. You can grasp at a glance the reason why it was evaluated as being in.

In the example shown in FIG. 6, the background image showing the rank of the physical condition evaluation result displayed on the two-dimensional map is centered on the standard value (1.0, 100). In the physical condition evaluation system according to the above, the center position of the background image displayed on the two-dimensional map can be changed based on a more appropriate criterion for evaluating the current physical condition. For example, if the average value of the past physical condition evaluation results of the evaluated person can be used as a standard value, and the standard value in this case is 105 for the reference heart rate and 0.9 for the heart rate response value, the background image. By setting the center of the "normal" area and the "slightly careful" area displayed as coordinates (0.9, 105), the center of each area is displayed deviated from the center of the map. As a result, the evaluated person can grasp the personal characteristics of the index (reference heart rate value and heart rate response value) related to his / her physical condition evaluation by looking at the two-dimensional map.

In the example shown in FIG. 6, the "normal" and "slightly careful" areas of the background image are both displayed as a substantially square centered on the standard value, but the area displayed as the background image is not included in this area. Not limited. The shape indicating at least one of "normal" and "slightly careful" should be a vertically long or horizontally long rectangular shape with different display widths of the reference heart rate value and the heart rate response value on the map. Can be done. It is also possible to make the centers of the two areas different.

Further, the size of each area determined by the threshold value for classifying each state (normal, slightly careful, caution) may be determined by using a predetermined predetermined value or by feeding back the past data of the evaluated person. You may. For example, fluctuations in the reference heart rate and the heart rate response value obtained from the past data of the evaluated person may be reflected in the size of the region.

In the physical condition evaluation system according to the present embodiment, the standard value uses the past average value of the evaluated person as described above, and for example, if the past data of the evaluated person is not accumulated, a predetermined predetermined value is determined in advance. The value may be used, or the numerical value obtained based on the physical condition evaluation result for a larger group accumulated as big data can be used as the standard value. It is also possible to use the average value of the evaluation results obtained for workers working in the same environment as the evaluated person as the standard value. As described above, in the physical condition evaluation system according to the present embodiment, a more preferable standard value can be selected so that more accurate physical condition evaluation can be performed.

The numerical ranges of the indicators on the vertical and horizontal axes of the two-dimensional map shown in FIG. 6 are the upper and lower limits of the reference heart rate value and the heart rate response value that may be calculated in the physical condition evaluation system according to the present embodiment. Can be set between. Also, since the area outside each axis is the "attention" area, at least the numerical range of each axis is displayed so that the range of the "attention" state defined based on the difference from the standard value is displayed. Should be decided.

FIG. 7 is a second display example of the two-dimensional map displayed in the second display area of the display screen of the smartphone possessed by the operator in the physical condition evaluation system according to the present embodiment.

As shown in FIG. 7, the 2D map 80 of the modified example has the vertical axis of the 2D map, the index of the horizontal axis, the numerical range, and the standard value and the area range of the ranking of the physical condition evaluation results displayed on the 2D map. Are all the same as the two-dimensional map 70 shown in FIG. 6, but the area 81 showing the "normal" state and the area 82 showing the "slightly careful" state of the background image displayed on the two-dimensional map 80. However, it is different in that it is circular or oval instead of rectangular as shown in the two-dimensional map 70 shown in FIG.

By doing so, when both the reference heart rate value and the heart rate response value, which are indicators of physical condition evaluation, are close to the boundary where the difference from the standard value becomes the next rank, the rank is stricter as a whole. Since it can be displayed as being in, it is possible to encourage the evaluated person to be careful about his / her physical condition, and it is possible to evaluate the physical condition on the safer side. It should be noted that even in the background image showing the circular region illustrated in FIG. 7, the points that the shapes, center positions, etc. of the two regions "normal" and "slightly careful" may be different are shown in FIG. It is the same as the background image showing the area on the shown rectangle.

As described above, in the physical condition evaluation system according to the present embodiment, a two-dimensional map centered on the reference heart rate value and the heart rate response value, which are indexes for evaluating the physical condition of the evaluated person, is created, and the two-dimensional map is created. A background image ranked on the map according to the difference from a predetermined standard value is displayed, and the evaluation value of the evaluated person is plotted. For this reason, the evaluated person can grasp at a glance the evaluation degree of each of the two indicators and the comprehensive physical condition evaluation result of his / her physical condition evaluation result, and take a break if necessary. You can manage your own physical condition by doing.

In the physical condition evaluation system according to the present embodiment, the display showing the physical condition evaluation result displayed on the mobile terminal possessed by the worker 10 as the evaluated person is the rank of the physical condition evaluation result shown in FIGS. 6 and 7. It is not limited to a two-dimensional map in which areas are divided based on. Hereinafter, a display example showing the physical condition evaluation result of the evaluated person in the physical condition evaluation system according to the present embodiment will be described.

FIG. 8 is a diagram showing a third display example of a two-dimensional map showing a physical condition evaluation result.

In FIG. 8, similarly to FIGS. 6 and 7, the physical condition evaluation result of the evaluated person is shown on a two-dimensional map in which the reference heart rate value and the heart rate response value are represented by two axes. The difference is that the background image of the map 90 is not classified into ranks representing the physical condition evaluation results. In FIG. 8, instead of the area for ranking the physical condition evaluation results, a circular gradation figure whose density or color gradually changes from the central portion 91 to the peripheral portion is shown, and a circular gradation figure whose color changes gradually is shown on the gradation figure. The evaluation result of the evaluator is displayed as a plot 92.

In this way, regarding the physical condition evaluation, the evaluation result of oneself is shown as a plot 92 on the dimension gradually changing from the center 91 which is the reference value, so that the evaluated person can evaluate the evaluation result of his / her physical condition. Similar to the two-dimensional maps of FIGS. 6 and 7 in which the ranked regions are shown, the magnitude of the difference from the standard value and the direction of deviation can be visually understood. In this way, the method of expressing the difference from the standard value step by step includes the display by such a gradation.

In FIG. 8, the shape of the gradation is circular, but it can also be represented by other figures such as an oval, an ellipse, a rectangle, and a polygon. Further, in FIG. 8, the standard value portion, which is the center 91 of the two-dimensional map 90, is shown as a gradation in which the center portion is the darkest and the periphery is thin. Needless to say.

FIG. 9 is a diagram showing a fourth display example of a two-dimensional map showing a physical condition evaluation result.

FIG. 9 shows the physical condition evaluation result of the subject on a two-dimensional map in which the reference heart rate value and the heart rate response value are represented by two axes, as in FIGS. 6 to 8. On the map 100, only the mark (star shape: 101) indicating the standard value of the physical condition evaluation result and the dot (dot: 102) indicating the own evaluation result are displayed.

Even in this way, the evaluated person can visually grasp the difference and the direction of deviation from the value of his / her physical condition evaluation result with respect to the standard value which is the standard of physical condition evaluation from the positional relationship of the two-point plot. As a result, it is possible to visually understand one's own physical condition evaluation result as in the two-dimensional map of FIGS. 6 to 8 in which the area in which the evaluation result is ranked is shown.

In order to help the evaluated person's understanding, a two-dimensional map such as "standard value" near the mark 101 indicating the standard value and "measured value" or "you" near the dot 102 indicating the evaluation result is displayed. It is more preferable to ensure that the content is understandable.

Further, in the physical condition evaluation system according to the present embodiment, the map showing the physical condition evaluation result of the evaluated person shows the evaluation result with the reference heart rate value and the heart rate response value as two axes as shown in FIGS. 6 to 9. It is not limited to a two-dimensional map.

FIG. 10 is a diagram showing a fifth display example showing the physical condition evaluation result of the evaluated person in the physical condition evaluation system according to the present embodiment.

In the fifth display example shown in FIG. 10, the evaluation result of the evaluated person is displayed on a horizontal bar 111 having the characters "normal" at one end and "caution" at the other end. ●: Shown by 112).

In FIG. 10, it is not the two indexes of the reference heart rate value and the heart rate response value represented as the axes of the two-dimensional map, but is a comprehensive index obtained by the data processing unit 22 in consideration of these two indexes. The position of the figure 112 on the horizontal bar 111 is determined according to the physical condition evaluation value.

By doing so, the worker 10 who is the evaluated person is in a state close to "normal", which is the same as usual, or the physical condition of the worker 10 is changed from the usual physical condition. It is possible to visually grasp whether the condition is close to the "attention" that is being taken, and take appropriate measures such as taking breaks to recover the physical condition.

The data processing unit 22 may calculate the Euclidean distance between the coordinates indicating the reference heart rate value and the heart rate response value acquired from the evaluated person and the coordinates indicating the standard value on the two-dimensional map as the physical condition evaluation value. For example, on the two-dimensional map of FIG. 9, when the coordinates of the dot 102 indicating its own evaluation result are (Mx, My) and the coordinates of the mark 101 indicating the standard value are (Sx, Sy), the following equation ( The physical condition evaluation value P can be calculated using 2).

P = √ {(Sx-Mx) ² + (Sy-My) ² } (2)
Of course, the method of calculating the physical condition evaluation value is not limited to the above formula, and the physical condition evaluation value can also be obtained as a linear sum obtained by multiplying the reference heart rate value and the heart rate response value by a predetermined coefficient.

FIG. 11 is a diagram showing a sixth display example showing the physical condition evaluation result of the evaluated person in the physical condition evaluation system according to the present embodiment.

In FIG. 11, each of the two indexes for evaluating the physical condition of the evaluated person is "normal" on the bars 121 and 122 divided into three areas of "normal", "slightly careful", and "attention". It is shown by bar graphs 123 and 124 extending from the area side of "" toward the area of "attention".

The map shown in FIG. 11 is not a two-dimensional map as shown in FIGS. 6 to 9, but the evaluation result of each index for evaluating the physical condition of the evaluated person is based on the degree of deviation from the standard value. How it is evaluated can be grasped from the position of the tip of the bar graphs 123 and 124. In the example shown in FIG. 11, only the evaluation results of the reference heart rate value and the heart rate response value are shown, but the physical condition evaluation value, which is a comprehensive physical condition evaluation index described with reference to FIG. 10, is also displayed. By doing so, the evaluated person can grasp the overall evaluation result of his / her physical condition.

FIG. 12 is a diagram showing a seventh display example showing the physical condition evaluation result of the evaluated person in the physical condition evaluation system according to the present embodiment.

Similar to the map shown in FIG. 11, the map shown in FIG. 12 represents each of the two indexes for evaluating the physical condition of the evaluated person, and the horizontal bar 131 showing the reference heart rate value and the horizontal bar showing the heart rate response value. In 132, the standard value of each index is shown in the center, and the evaluation results of the evaluated persons are plotted by ● in plots 133 and 134. According to the map shown in FIG. 12, the evaluated person has a difference between the standard value, which is the degree of the evaluation result value, which is lower (left side in the figure) or higher (right side in the figure) than the standard value. The size can be visually grasped.

In addition, FIG. 10 shows an example of displaying the physical condition evaluation result in a state where the area is not distinguished, and FIG. 11 shows an example of displaying the physical condition evaluation result using the area determined by the degree of deviation from the standard value. .. Further, in FIG. 12, an example is shown in which the standard value is clearly shown on the horizontal bar, which is a one-dimensional map, and the direction of the difference from the standard value and its magnitude are displayed so as to be understood. As described above, the display of the display screen of the smartphone possessed by the evaluated person in the physical condition evaluation system according to the present embodiment can adopt various forms in which the physical condition evaluation result can be easily visually grasped.

Further, the evaluation results of the evaluated person are shown by dots in FIGS. 10 and 12, and at the position of the tip of the bar graph in FIG. 11, but the physical condition evaluation result of the evaluated person is visually observed regardless of which display form is used. Needless to say, it can be displayed by a method different from the methods illustrated respectively.

In the example showing the physical condition display result of the evaluated person on the one-dimensional map (horizontal bar) shown in FIGS. 10, 11, and 12, the method of showing the position of the evaluation result shown in FIG. 10 with dots. In addition to the method of showing the position of the evaluation result shown at the tip of the graph shown in FIG. 11, a method of showing the position of the evaluation result using a plurality of segments, a method of showing the position of the evaluation result using a figure such as an arrow, and the like are predetermined. Various conventionally known methods can be used as a method for displaying the relative position of the numerical value of.

Further, the method of showing the physical condition evaluation result on the one-dimensional map is not limited to the method shown on the horizontal bar used in FIGS. 10 to 12, and the coloring shown on the figure such as the cylinder shown in the horizontal direction is not limited. Change the size of the colored area in the figure showing the size of the area, the method shown on the vertical bar, and the figure symbolizing the good or bad of the physical condition, for example, the figure such as the fuel tank or the flame showing the amount of energy. It can also be displayed.

Further, as a method of displaying the physical condition evaluation result in the physical condition evaluation system in the present embodiment, in addition to the index to be displayed using the two-dimensional or one-dimensional map described with reference to FIGS. 6 to 12, the evaluation result numerical value is displayed. It is possible to adopt a method of displaying as it is, a method of displaying the rank of the evaluation result (“normal”, “slightly careful”, “caution”) in characters, and the like. When displaying the physical condition evaluation result without using these figures, by coloring the color of the numerical value or the character itself or the figure surrounding the area where the numerical value or the character is displayed based on the rank of the evaluation result, in particular. It is preferable to be able to appeal to the eyes of the evaluated person more strongly when the physical condition evaluation result indicates a state requiring attention.

FIG. 13 is a diagram showing an eighth display example showing the physical condition evaluation result of the evaluated person in the physical condition evaluation system according to the present embodiment.

FIG. 13 is an example showing the transition of the physical condition evaluation value of the evaluated person with the passage of time. More specifically, the transition 141 of the physical condition evaluation value of the evaluated person from the start of the work on the day of evaluation is shown. In the example shown in FIG. 13, the physical condition evaluation value in the morning shown on the left side of the figure is average. It is high, especially before noon, it is close to the value ranked as "attention", but in the afternoon, the physical condition evaluation value 141 becomes close to "normal" and continues until dot 142 indicating the current time. ing.

In this way, by displaying the transition of the numerical value indicating the physical condition evaluation result of the evaluated person, the evaluated person can grasp the change in his / her physical condition. As shown in FIG. 13, there is no problem when the physical condition evaluation result is approaching the state of being ranked as "normal", but conversely, when the evaluation result is approaching the area of being ranked as "caution". It is necessary for the evaluated person to pay attention to the change in his / her physical condition.

In addition, although FIG. 13 shows an example showing the transition of the physical condition evaluation value which is an overall index of the physical condition evaluation of the evaluated person, the transition of the reference heart rate value and the heart rate response value which are the criteria of the physical condition evaluation is shown. It can also be displayed together, and it is also possible to display only the transition between the reference heart rate value and the heart rate response value without displaying the transition of the physical condition evaluation value.

In addition to showing the transition of the physical condition evaluation result by time on the evaluation day, for example, the transition of the physical condition evaluation result for each evaluation day for the last week or so is appropriately preferable for the period showing the transition. Can be set to.

FIG. 14 is a diagram showing a ninth display example showing the physical condition evaluation result of the evaluated person in the physical condition evaluation system according to the present embodiment.

FIG. 14 shows an example of a display image on the manager information terminal 31 used by the on-site supervisor 30 who is the manager in the heat stroke onset risk management system equipped with the physical condition evaluation system of the present embodiment. As shown in FIG. 14, by displaying the physical condition evaluation results of the plurality of workers 10 managed by the site supervisor as a list on the display device 36 of the administrator information terminal 31, the site supervisor 30 is each person. You can easily grasp your physical condition.

It should be noted that FIG. 14 illustrates a state in which "normal", "slightly careful", and "caution" are shown as the physical condition evaluation results according to the ranks classified by the difference from the predetermined standard value. The physical condition evaluation value can be expressed as a numerical value, and the reference heart rate value and the heart rate response value can be added to the physical condition evaluation value or can be displayed without displaying the physical condition evaluation value. In this case, the color of the displayed characters and numerical values, or the color of the entire corresponding frame or column of the displayed table is different depending on the evaluation result, and in particular, the work evaluated as being in the "Caution" state. It is more preferable to make the person stand out.

The list of physical condition evaluation results of the evaluated person to be managed shown in FIG. 14 can be displayed on the management computer 41 at the business establishment 40 in addition to the manager information terminal 31 of the site supervisor 30. It is preferable that the person in charge at the place 40 can support the physical condition management of the worker 10 by the on-site supervisor.

Further, if necessary, the physical condition evaluation results of the members of the group to which the worker 10 belongs can be displayed as a list on the display screen of the smartphone 11 possessed by each worker 10.

In addition, in FIG. 13, an example showing a list of the physical condition evaluation results of the worker 10 displayed on the manager information terminal 31 of the site supervisor 30 as a list has been described. However, the method of displaying the list of the physical condition evaluation results of all the workers to be managed is not limited to the format of the list. For example, the two-dimensional evaluation map shown in FIG. 6 has a plurality of objects. The physical condition evaluation result of the evaluator can be displayed as dots, and in this way, the on-site supervisor who is the manager can grasp the overall tendency of the physical condition evaluation result of the worker to be managed. It is also possible to display the name and management ID so that the worker can be identified in the vicinity of the dot indicating the evaluation result of each evaluated person.

As described above, in the physical condition evaluation system according to the present embodiment, the reference heart rate value and the heart rate of the evaluated person are based on the heart rate data and the acceleration data acquired by the biological information acquisition unit worn by the evaluated person. The response value and the physical condition can be evaluated. Then, by displaying the physical condition evaluation result based on the reference heart rate value and the heart rate response value on the display screen, the evaluated person can visually grasp his / her physical condition evaluation result, and it is necessary to pay attention to the physical condition change. If you are evaluated, you can manage your physical condition by taking measures such as resting your body.

In the above embodiment, it has been explained that when the physical condition evaluation results are ranked according to the difference from a predetermined standard value, they are divided into three ranks, "normal", "slightly careful", and "caution". .. However, this ranking is just an example, and it is possible to divide it into two or four or more ranks instead of three ranks, and the name of each rank is limited to those that are good. Needless to say, there isn't.

The physical condition evaluation system disclosed in this application is installed together with a system in which the manager manages the risk of heat stroke of workers who work in a state where the physical load and the heat load are large, such as construction sites and transportation industries, and various types are installed. It is possible to evaluate the physical condition of the managed person under various circumstances. In addition, the physical condition evaluation system disclosed in this application is used for a wide range of purposes such as physical condition management of workers at construction sites and factories, physical condition management of residents of sports gyms and facilities for the elderly, and physical condition management of athletes during training. It is useful as a physical condition management system that enables the evaluated person to visually understand the result of his / her physical condition evaluation.
