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

  FIG. 2 is a block diagram illustrating a configuration example of each unit of the heat stroke risk management system in which the physical condition evaluation system according to the present embodiment is mounted.

  As shown in FIG. 1, a worker 10 (evaluated person) who is a manager who works at a construction site obtains biological information such as body temperature (body surface temperature), heart rate, and sweating amount. And a smartphone 12 as a portable terminal that functions as a biological information transmission unit 13 that transmits biological 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 that acquires the biological information of the worker 10 is attached to the chest of an undershirt worn by the worker 10.

  FIG. 3 is a diagram illustrating a configuration example of an undershirt worn by an operator in the heat stroke risk management system according to the present embodiment. Fig.3 (a) has shown the surface of the undershirt with which the biometric information acquisition part was mounted | worn, and FIG.3 (b) has shown the back surface of the undershirt.

  As shown in FIG. 3, the data chip 11 is arranged on the chest of the undershirt 18 worn by the operator 10 in the heat stroke risk management system according to the present embodiment. More specifically, the data chip 11 is connected to the data acquisition / transmission unit 11a and the data acquisition / transmission unit 11a arranged in the chest central portion of the front surface 18a of the undershirt 18, and the back surface 18b of the undershirt 18 That is, it is comprised from the electrode part 11b arrange | positioned by extending in the left-right direction in the part in the side which touches skin.

  In the heat stroke risk management system described in the present embodiment, as a method of acquiring the biological 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. It is not limited to. For example, a method in which the data chip 11 is placed in a sheet-like mounting cover with high adhesiveness and this is directly attached to the chest, and work is performed using a stretchable mounting belt that can hold the data chip 11 in close contact with the body. For example, a method of placing on the chest of a person can be employed. However, in the method using the mounting cover or the mounting belt, the discomfort that the operator 10 feels by mounting the data chip 11 cannot be resolved. There is a risk of disengagement from the body surface or displacement of the wearing position.

  On the other hand, according to the method of fixing the data chip 11 to the undershirt 18 worn by the operator 10 as shown in FIG. Biological information can be acquired without being conscious. Even if the worker 10 sweats or the body twists during work, the data chip 11 fixed to the undershirt 18 is not completely detached from the body surface of the worker 10. Even if the electrode part 11b temporarily moves away from the chest surface of the operator 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 for detecting acceleration in two or three directions on the data chip 11 for obtaining the biological information of the worker 10, acceleration data indicating the movement of the worker 10's body 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. Also, when the posture of the worker 10 changes suddenly, such as when the worker 10 falls, the data chip 11 can detect the movement of the body.

  When the data chip 11 is used as a biometric information acquisition unit that acquires the biometric information of the worker 10, the data chip 11 is disposed at the waist, back, upper arm of the worker in addition to the chest of the worker as described above. In addition, it is possible to adopt a form that is arranged on the wrist or the leg. Even in these cases, the data chip 11 is fixedly fixed to the body surface of the worker by using a mounting cover or a mounting belt as well as a method of arranging the data chip on the inner surface of the underwear. Can be used. However, it is necessary to detect heartbeat data as biometric information, and in addition to accurately detecting the movement of the entire body as the movement 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 worker 10, and it is most preferable to use an 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 is constantly updated. It is sent to the smartphone 12. In addition, in the case where connection is possible with a signal line having a thickness that does not give the operator 10 a sense of incongruity, 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 a data reception unit 15 and a data transmission unit 16 included in the smartphone 12 using an information carrier of a wireless LAN or a mobile phone. Then, the smartphone 12 transmits the biological information of the worker 10 to the cloud server 21 that is a server provided with the data processing unit 22 installed on the Internet 20. The smartphone 12 includes an image display unit 17 as a display unit that displays the physical condition evaluation result of the person to be evaluated 10 evaluated by the physical condition evaluation system.

  The cloud server 21 includes a data reception unit 23 and a data transmission unit 26 therein, and can transmit and receive information via the Internet 20, and also includes a data processing unit 22, and includes a plurality of workers. The biometric information is received to determine the risk of developing heat stroke for each worker, and when the risk of developing heat stroke is increased, warning information is generated to warn the worker of that fact. In addition, the cloud server 21 includes a data recording unit 24, and can record the biometric information, warning information creation history, and the like of each of a plurality of workers in time series.

  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. Weather conditions at the current time, such as temperature, humidity, and amount of sunlight, and weather forecasts that anticipate changes within the next few hours can be acquired.

  In addition, the cloud server 21 is a personal computer 31 as an administrator information terminal used by the site supervisor 30 who is an administrator who supervises the work of the worker 10 whose risk of developing heat stroke is determined at the construction site via the Internet 20. Connected with. Therefore, the site supervisor 30 at the work site of the worker 10 determines whether or not the biological information and warning information of the worker 10 transmitted from the cloud server 21 at any time are generated by the data receiving unit 33 of the personal computer 31. I can grasp it.

  The data processing unit 22 of the cloud server 21 functions as a risk determination unit that determines the risk that the worker 10 will develop 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 the risk of developing heat stroke is increased based on the resting data that is the biological information of the worker 10 at rest. The risk of developing heat stroke of the worker 10 can be determined by comparing the threshold value with the working data that is biometric information.

  Furthermore, 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. For this reason, the data processing unit 22 acquires the heart rate data and acceleration data of the evaluated person acquired by the data chip 11 via the biological information transmission unit 13 of the portable terminal 12 and evaluates the physical condition in the physical condition evaluation system. A reference heart rate value and a heart rate response value as a reference to be calculated are calculated. 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. Do.

  In addition, the cloud server 21 includes the past history information of the determination target worker 10 recorded in the data recording unit 24, the weather information of the work area acquired by the weather information acquisition unit 25, and 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, the judgment result of the risk of developing heat stroke of the worker 10 is corrected to be more realistic. Can be. Furthermore, also in the physical condition evaluation system, the data processing unit 22 functioning as an index calculation unit based on the evaluation result of the evaluation subject recorded in the data recording unit 24 can more accurately determine the reference heart rate value of the evaluation subject. And a heartbeat response value can be calculated.

  In the heat stroke risk management system equipped with the physical condition evaluation system described in the present embodiment, the data server 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 office. If the function can be realized, Any device is acceptable.

  The personal computer 31 of the site supervisor 30 (manager) as the manager information terminal has generated biometric information and warning information about workers belonging to the work site supervised by the site supervisor 30 including the worker 10. An information management unit 32 for managing the above is provided. Based on the information transmitted from the cloud server 21, the information management unit 32 always grasps the heat stroke onset risk information as to whether each worker's biological information and warning information have been generated as the latest information. In addition, the information management unit 32 outputs the acquired heat stroke risk information and other environmental information of each worker to the display image processing unit 35, and the display image processing unit 35 places the information on a display device 36 such as a liquid crystal monitor. The displayed screen content is adjusted. In this way, the on-site supervisor 30 can easily view the biological information and the risk of developing heat stroke of the worker 10 who works at the work site supervised as a whole or as detailed information for each worker. I can grasp it.

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

  As shown in FIG. 1, when the personal computer used by the field supervisor is a desktop type, the display device 36 is separate from the personal computer body. Thus, the administrator information terminal 31 including the information management unit 32 and the display device 36 that performs screen display for the administrator are not limited to physically integrated ones. For example, when confirming data by a plurality of people, a dedicated large-sized image display device may be used, or a display image may be enlarged and projected on a screen or a wall surface by a projector.

  Further, the personal computer 31 of the field supervisor 30 receives the biological information of the worker 10 after notifying the warning information and the receipt confirmation of the warning information from the worker 10, thereby preventing the worker 10 from developing heat stroke. If the worker 10 is not taking measures to prevent the onset of heat stroke, the warning information is repeatedly transmitted to the target worker 10. For example, the operator 10 can be alerted.

  In the above description, the warning information for notifying the worker 10 that the risk of developing heat stroke is increased is described in the data processing unit 22 of the cloud server 21, but the warning information is It can be generated by the information management unit 32 installed in the personal computer 31 of the field supervisor 30. It is also possible to set so that warning information is generated by both the data processing unit 22 and the information management unit 32. By doing in this way, warning information is generated prior to the determination result in the data processing unit 22 from the personal computer 31 of the site supervisor 30 who actually supervises the work site, and is transmitted to the symmetric worker 10. Thus, the risk of developing heat stroke may be further reduced depending on the actual situation at the work site.

  Warning information generated by the data processing unit 22 of the cloud server 21 or the personal computer 31 of the site supervisor 30 is sent from the data transmission unit 34 of the personal computer 31 of the site supervisor 30 to a local network such as a wireless LAN or an information carrier of a mobile phone. Is transmitted to the smartphone 12 equipped by the worker 10 via a network including Upon receiving the warning information, the warning notification unit 14 of the smartphone 12 develops heat stroke to the worker 10 by using various information transmission means such as voice, screen display, lamp lighting or blinking, 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 or the operation button of the smartphone 12 and performs measures such as interrupting the work and taking a rest.

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

  Furthermore, 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 You can check the current status of heat stroke risk at the workplace where you work. For example, if it can be confirmed that the risk of developing heat stroke of workers other than themselves is high, each worker himself can take measures against heat stroke. In addition, if it is found that there is another worker who has received the warning information about the risk of developing heat stroke and has suspended the work, the worker 10 who has received the warning information from the field supervisor 30 can respond to the warning information more honestly. Can be expected.

  Furthermore, with the smartphone 12 owned by the worker 10, changes in the risk of developing heat stroke until the present time of the worker 10, own biological information numerical values acquired by the data chip 11, calorie consumption calculated from the biological information, etc. The related information can be displayed on the screen and can be referred to by the operator 10 himself.

  Moreover, in the heat stroke onset risk management system of this 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. For this reason, the image display unit 17 displays the physical condition evaluation result of the worker 10 as the person to be evaluated who is the holder of the smartphone 12 and the physical condition evaluation result in a form easy to understand for the worker 10. And an image data creation unit. In addition, 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 office 40 to which the worker 10 belongs through the Internet 20, and the biological information of the worker 10 transmitted to the personal computer 31 of the site supervisor 30, the cloud Various information used by the server 21 to determine the risk of developing heat stroke, as well as the reference heart rate value and the heart rate response value of the worker 10 calculated by the data processing unit 22, in real time. It is transmitted to 40 management computers 41. Since the management computer 41 of the business office 40 has 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. It is possible to confirm information such as whether the warning information has been correctly transmitted or whether the worker 10 has taken preventive measures against heat stroke, and can give predetermined instructions as necessary. By doing in this way, also in the business office 40 to which the worker 10 belongs, the situation of the worker 10 and the response at the work site can be confirmed, and the avoidance of the heat stroke risk of the worker 10 is backed up. be able to.

  Although not explicitly shown in FIG. 1, the cloud server 21, the personal computer 31 of the site supervisor 30, and the management computer 40 of the business office 40 are connected via the Internet 20. The cloud server 21 can be accessed from, and the data processing content in the cloud server 21 can be controlled, the data processing program in the data processing unit 22 can be updated, or heat stroke risk management can be performed from the cloud server 21. Information can be taken out as appropriate. Furthermore, the physical condition evaluation result of the worker 10 who is the person to be evaluated, which is evaluated by the physical condition evaluation system installed together, is displayed on the screen of the personal computer 31 of the site supervisor 30 and the management computer 40 of the business office 40. Thus, the physical condition evaluation result of each worker can be grasped.

  In the above description, a smartphone is exemplified as a mobile terminal equipped by an operator, but the worker's mobile terminal is not limited to a smartphone, and is specialized in a mobile phone, a tablet device, and further a heat stroke risk management system. Thus, it is possible to use a dedicated small terminal device capable of displaying information transmission / reception and physical condition evaluation results.

  The manager information terminal operated by the on-site supervisor is not limited to the exemplified personal computer, especially the desktop personal computer shown in FIG. 1, and other devices such as laptop computers, tablet computers, small server devices, etc. Various information devices capable of displaying data and recording data can be employed.

  Further, in the above description, the form in which the warning information is transmitted from the manager information terminal of the field supervisor to the portable terminal of the worker has been described. However, 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.

  In addition, when managing the onset risk of the heat stroke of the worker in a construction site with the heat stroke onset risk management system illustrated 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 transmission of the biometric information of each worker to the supervisory information terminal of the field supervisor is performed on the Internet. It can be performed within the LAN without intervention. In this case, by connecting to the Internet from an administrator information terminal or from an information device such as a server unit or another personal computer installed in the LAN, the risk determination unit in the cloud server can It is possible to make a determination or use the weather information acquired by the weather information acquisition unit. Moreover, the risk determination part which determines the onset risk of heat stroke can be provided in the server unit or personal computer connected to the LAN of the construction site.

To do.

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

  In FIG. 4, the vertical axis indicates the heart rate of the person to be evaluated, and the unit is (bpm). In addition, the horizontal axis represents acceleration representing the intensity of movement of the body of the measurement subject, and the unit is (G: gravity 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 that is a change in voltage at the electrode portion 11b. The number of peaks per minute of this heartbeat waveform is the heart rate (bpm) of the person to be evaluated 10. The heart rate is not limited to the method of directly counting the number of peaks of the heartbeat waveform for 1 minute. For example, the number of peaks for 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, 3 minutes, etc., is counted and converted to a heart rate per minute The heart rate (bpm) per unit time (1 minute) can be obtained using various methods such as adopting a method.

  In particular, when the operation 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, and therefore one heartbeat waveform and the next It is also possible to employ a method of calculating the heart rate per minute from the time difference between the peaks of the detected heartbeat waveform. As described above, when the heart rate is obtained from the peak interval of the heart rate waveform, the calculated heart rate becomes an extremely small value if the heart rate waveform corresponding to the continuous heart rate is not detected. For this reason, based on the characteristics of the pulse of the human body that the numerical value does not change to about 70 to 110, and the numerical value does not change by more than 20 to 30% within a few seconds, the electrode portion 11b It is preferable to determine the likelihood of the heart rate obtained from the interval between the obtained heartbeat waveforms, and to perform a process of sieving such that the data does not work if the data is inaccurate.

  In addition, when the ratio of the number of cases determined to be inaccurate data as a result of sieving in a predetermined period such as 1 minute exceeds a threshold value set as 50% as an example, data It is judged that the attachment abnormality of the chip 11 has occurred, and the subject is checked whether the data chip 11 is correctly in contact with the chest, and the wearing state of the undershirt 18 is corrected, It can be confirmed whether or not an abnormal situation such as a battery running out of the chip 11 has occurred.

  If such a data chip attachment abnormality or battery exhaustion occurs, the heat stroke risk management system will not operate properly, so the operator 10 works directly or through the field 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 acquired correctly.

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

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

  In the physical condition evaluation system according to the present embodiment, since the body movement of the person to be evaluated 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 in three directions. For these data, for example, a statistical method such as an exponential moving average method is used to exclude the entire noise component, and then the magnitude of acceleration in each axis direction for a predetermined period is obtained. Thereafter, the sum of squares of acceleration values in the three-axis directions is obtained, and the mean square value of acceleration is obtained by dividing by the number of data, and further, acceleration data of the evaluated person is calculated from the square root.

  Note that the above-described statistical processing method of the heart rate data and acceleration data is merely an example. For example, taking into account the intensity of movement of the body of the person to be evaluated, the heart rate data and acceleration data obtained from the data chip from time to time are used. Various methods that can accurately grasp the heart rate and body acceleration of the person to be evaluated can be employed.

  By using a regression line for the correlation between the heart rate data indicating the heart rate of the person to be evaluated and the acceleration data indicating the body movement at the time when the heart rate data was obtained, Value and heart rate response value are calculated.

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

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

  The y-axis intercept of the regression line thus obtained, that is, the heartbeat-side intercept 52 represents the reference heart rate value of the subject. This reference heart rate value estimates the heart rate of the evaluator 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 or a heart rate index.

  In addition, the slope of the regression line 51 indicates the degree of increase in the heart rate of the person to be evaluated with respect to the intensity of body movement. In the physical condition evaluation system of this embodiment, in order to eliminate the individual difference in the numerical value of the slope of the regression line, the slope αi of the regression line at the time of evaluation of the measured person is used as a reference, as in the following formula (1). The numerical value α obtained by dividing the regression line slope α0 of the obtained data as the heart rate response value of the person to be evaluated.

Heartbeat response value α = αi / α0 (1)
Here, as the reference data α0, the slope value of the regression line calculated based on the data of a large number of people called big data can be used. In addition, when evaluating the physical condition change with respect to the normal physical condition of the evaluator, the slope of the regression line obtained from all or part of the past measurement data of the evaluator as α0 which is the reference data Can be used. For example, α0 may be obtained from the acquired data on the previous day of the evaluated person. As described above, the heartbeat response value α is data normalized so that the slope αi of the regression line at the time of evaluation of the subject is 1 when the slope αi is at the same level as the reference value (α0). Is preferred.

  The heartbeat response value obtained in this way is a value obtained by normalizing the degree of increase in heart rate due to the body movement of the person being evaluated at the time of measurement with standardized data. If it is large, it indicates that the rate of increase of the heart rate with respect to body movement is larger than the standard. For this reason, the heartbeat response value can be referred to as a cardiac performance evaluation value or a fitness index.

  The physical condition evaluation system according to the present embodiment indicates the physical condition at the time of measurement of the evaluated person using the reference heart rate value and the heart rate response value obtained in this way.

  As described above, in order to calculate the reference heart rate value and the heart rate response value, a plurality of combinations of heart rate data and acceleration data are required. For this reason, in the physical condition evaluation system concerning this embodiment, a physical condition evaluation of a to-be-evaluated person is performed based on the measurement result in a fixed period. As this fixed period, it is considered that data of several tens of minutes to several hours is necessary. Therefore, when displaying the measurement result on time, for example, the measurement result is updated every two hours from the display time point. May be. Moreover, the tendency of the to-be-evaluated person's overall physical condition can be evaluated by setting the fixed period, which is the measurement period, to half a day or one day. Further, by making the measurement period short, for example, in units of 30 minutes, it is possible to finely check the physical condition change of the person to be evaluated.

[Display physical condition evaluation results]
FIG. 5 is a diagram illustrating an example of a display screen of a smartphone that is a portable terminal possessed by the person to be evaluated in the physical condition evaluation system according to the present embodiment.

  As shown in FIG. 5, the display screen 60 shown as an example includes a first display area 61 that shows general information, a second display area 62 that displays the physical condition evaluation result of the possessed worker, and additional information. Is composed of three display areas including a third display area 63 for displaying the.

  At the top of the first display area 81, there is a belt-like portion for displaying general information of the smartphone such as the current time, battery remaining amount display, operation mode display, and other resident application software operation display.

  Below this belt-shaped part is a display part for displaying basic information in the physical condition evaluation system described in this embodiment. In the example shown in FIG. 5, the company name of the worker who is the person to be evaluated, the worker In addition to specific information related to the person being evaluated, such as the name of the construction site where the work works, buttons for displaying related information such as weather forecasts, past alert history, display screen setting change buttons, and forced Various operation buttons such as a button for updating data are arranged. In addition, although illustration is abbreviate | omitted, since the physical condition evaluation system concerning this embodiment is mounted in the heat stroke onset risk management system, the information in a heat stroke onset risk management system, for example, the heat stroke onset risk of a to-be-evaluated person An operation button for switching display contents can be arranged on a screen for displaying numerical values.

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

  In addition, in the lower part of the display screen 60 of the smartphone carried by the worker, as a third display area 63, various information relating to the operation of the physical condition evaluation system, and further, the evaluated person before starting the work Operation buttons for registering the group to which you belong, or changing the display of your own information to a 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, A button or the like that is operated at the start of work or at the start of work and switches management ON / OFF in the system is arranged.

  In addition, the display example of the smart phone 12 which is the 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 in an easy-to-understand manner for the worker 10. In addition, the worker 10 can select relevant information such as his / her calorie consumption and the progress of construction, and display the relevant information as appropriate. Further, it goes without saying that the display contents in the respective regions other than the region of the strip-like portion at the top of the first display region 61 shown in FIG. 5 can be appropriately changed in the display order in the vertical direction.

  In FIG. 6, the display content of the 2nd area | region of the display screen of the portable terminal which an operator possesses is expanded and shown.

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

  In this two-dimensional map 70, the vertical axis indicates the reference heart rate value and the horizontal axis indicates 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). It is a general standard value. In addition, a general standard value here shows the average value of the data of many people divided | segmented by big divisions, such as age, sex, etc., for example, the whole Japanese 40s man. Note that the average value of the data of the large number of people can be obtained as an actual measurement value based on the actual value of the entire actual users of the physical condition evaluation system shown in the present embodiment, which is called so-called big data. Moreover, about the data acquired by the various methods regarding the conventional physical condition and a health index, it can also obtain as a calculated value obtained by converting into the evaluation value at the time of using the physical condition evaluation system shown in this embodiment.

  Further, as shown in FIG. 6, the two-dimensional map displayed on the portable terminal of the person to be evaluated in the physical condition evaluation system according to the present embodiment is a stepwise difference between the standard value of the reference heart rate value and the heart rate response value. The expressed background image is displayed. Specifically, the area 71 is determined to be in the “normal” state, the area 72 is determined to be in the “somewhat caution” state, and the area 73 is determined to be in the “caution” state outside the area 72. ing. In addition, a plot 74 showing the position based on the latest reference heart rate value and heart rate response value (for example, the past two hours) is displayed as the current physical condition evaluation result of the subject. In addition, by changing the color of each area | region of the background image of a two-dimensional map, the difference with a standard value can be appealed visually to a to-be-evaluated person. In this case, for example, the “normal” region is colored with a blue or green color, “slightly caution” is colored with yellow or orange, and “caution” is colored with a red color. On the other hand, the difference from the standard value can be displayed in an easy-to-understand manner.

  Thus, in the physical condition evaluation system according to the present embodiment, the physical condition evaluation result 74 is displayed on the two-dimensional map 70 displaying the background images 71 to 73 expressing the difference from the standard value step by step. The evaluator can easily confirm whether the current physical condition is “normal”, “a little caution”, or “attention”. In addition, in the case shown in FIG. 6, since it is possible to grasp 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 physical condition of “somewhat attention” and “attention” It is possible to grasp at a glance the reason why it was evaluated to be.

  In the example illustrated in FIG. 6, the background image indicating the rank of the physical condition evaluation result displayed superimposed 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 superimposed on the two-dimensional map can be changed based on a more appropriate standard for evaluating the current physical condition. For example, an average value of past physical condition evaluation results of the person to be evaluated can be used as a standard value. In this case, if the standard value 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 caution” area displayed as the coordinates (0.9, 105), the center of each area is displayed shifted from the center of the map. Thereby, the to-be-evaluated person can grasp the personal characteristics of the indexes (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 caution” areas of the background image are both displayed in a substantially square shape centered on the standard value. Not limited. As a shape showing at least one of “normal” and “slightly caution”, it should be a vertically long or horizontally long rectangular shape with different display widths of the reference heart rate value and heart rate response value on the map Can do. It is also possible to make the centers of the two regions different.

  The size of each area determined by the threshold value for classifying each state (normal, slightly caution, caution) may be a predetermined value determined in advance, or determined by feedback of the past data of the person being evaluated. May be. For example, the fluctuation of the reference heart rate and the heart rate response value obtained from the past data of the person to be evaluated may be reflected in the size of the region.

  In the physical condition evaluation system according to the present embodiment, as the standard value, as described above, the past average value of the person to be evaluated is used, and for example, when there is no accumulation of the past data of the person to be evaluated, a predetermined predetermined value is used. A value may be used, or a numerical value obtained based on a physical condition evaluation result for a larger group accumulated as big data may be used as a standard value. In addition, an average value of evaluation results obtained for workers who work in the same environment as the person to be evaluated can be used as a standard value. Thus, 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.

  Note that the numerical ranges of the indices 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. In addition, since the area outside each axis is the “attention” area, the numerical value range for each axis is displayed so that at least the range of the “attention” state defined based on the difference from the standard value is displayed. If it is 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 worker in the physical condition evaluation system according to the present embodiment.

  As shown in FIG. 7, the modified two-dimensional map 80 includes a vertical value, a horizontal axis index, a numerical range of the two-dimensional map, a standard value and a region range for ranking physical condition evaluation results displayed on the two-dimensional map. Are all the same as the two-dimensional map 70 shown in FIG. 6, but the area 81 indicating the “normal” state and the area 82 indicating the “somewhat attention” state of the background image displayed on the two-dimensional map 80 However, it is different from the two-dimensional map 70 shown in FIG. 6 in that it is circular or oval.

  By doing this, 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 part where the difference from the standard value is the next rank, the overall stricter rank Therefore, the person to be evaluated can be encouraged to pay attention to his / her physical condition, and the physical condition can be evaluated more safely. In the background image showing the circular area illustrated in FIG. 7, the shape, center position, and the like of the two areas “normal” and “somewhat attention” may be different. This is the same as the background image showing the area on the indicated rectangle.

  As described above, in the physical condition evaluation system according to the present embodiment, a two-dimensional map is created with the reference heart rate value and the heart rate response value, which are indices for evaluating the physical condition of the evaluated person, as axes, respectively. The background image ranked according to the difference from a predetermined standard value on the map is displayed, and the evaluation value of the person to be evaluated is plotted. For this reason, the person being evaluated can grasp at a glance the evaluation level of each of the two indicators and the overall physical condition evaluation result of his / her physical condition evaluation result, and take measures such as taking a break as necessary. You can manage your physical condition.

  In addition, in the physical condition evaluation system according to the present embodiment, the display indicating the physical condition evaluation result displayed on the portable terminal possessed by the worker 10 who is the person to be evaluated is the rank of the physical condition evaluation result shown in FIGS. It is not limited to a two-dimensional map in which the area is divided based on Hereinafter, the display example which shows the to-be-evaluated person's physical condition evaluation result in the physical condition evaluation system concerning this embodiment is demonstrated.

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

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

  As described above, with respect to the physical condition evaluation, the evaluation result is shown as the plot 92 on the gradient gradually changing from the center 91 serving as the reference value, so that the evaluated person can evaluate the physical condition evaluation result with respect to the physical condition evaluation result. As in the two-dimensional maps of FIGS. 6 and 7 in which the regions that are ranked are shown, it is possible to visually understand the magnitude of the difference from the standard value and the direction of deviation. In this way, the method of expressing the difference from the standard value in stages includes such gradation display.

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

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

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

  Even in this way, the person to be evaluated can visually grasp the difference and the direction of deviation from the physical condition evaluation result numerical value with respect to the standard value that is the reference for the physical condition evaluation from the positional relationship of the two points of the plot. The physical condition evaluation result can be visually understood in the same manner as the two-dimensional maps of FIGS.

  In order to help the person to be evaluated, a two-dimensional map is displayed such as “standard value” in the vicinity of the mark 101 indicating the standard value and “measured value” or “you” in the vicinity of the dot 102 indicating the own evaluation result. More preferably, the contents can be surely understood.

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

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

  In the fifth display example shown in FIG. 10, the physical condition evaluation result is displayed on a horizontal bar 111 in which “normal” is displayed on one end and “caution” is displayed on the other end. ●: 112).

  In FIG. 10, it is not the two indices of the reference heart rate value and the heart rate response value that are 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 indices. The position of the graphic 112 on the horizontal bar 111 is determined according to the physical condition evaluation value.

  By doing in this way, the worker 10 who is the person to be evaluated is in a state close to “normal” that does not change with respect to his / her physical condition evaluation result, or changes in his / her physical condition compared to his / her normal physical condition. It is possible to visually grasp whether the state is close to “caution” and to take measures such as taking an appropriate break to try 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 on the two-dimensional map and the coordinates indicating the standard value 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 formula ( 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 illustrating a sixth display example illustrating the physical condition evaluation result of the person to be evaluated in the physical condition evaluation system according to the present embodiment.

  In FIG. 11, for each of the two indicators for evaluating the physical condition of the person to be evaluated, each of the bars 121 and 122 divided into three areas of “normal”, “somewhat attention”, and “caution” is “normal”. The bar graphs 123 and 124 extend from the “” area side toward the “caution” area.

  The map shown in FIG. 11 is not a two-dimensional map as shown in FIG. 6 to FIG. 9, but for each index for evaluating the physical condition of the person being evaluated, the evaluation result is different from the standard value. It can be grasped from the positions of the tips of the bar graphs 123 and 124 how they are evaluated. In the example shown in FIG. 11, only the evaluation results for the reference heart rate value and the heart rate response value are shown. However, the physical condition evaluation value, which is the comprehensive physical condition evaluation index described with reference to FIG. 10, is also displayed. By doing this, the person to be evaluated can grasp the overall evaluation result of his / her physical condition.

  FIG. 12 is a diagram illustrating a seventh display example indicating the physical condition evaluation result of the person to be evaluated 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. The horizontal bar 131 indicates the reference heart rate value, and the horizontal bar indicates the heart rate response value. 132, the standard value of each index is shown in the center, and the evaluation results of the person to be evaluated are plotted 133 and 134 in black. With the map shown in FIG. 12, the person to be evaluated is the difference between the evaluation result numerical value of the standard value which is lower (left side in the figure) or higher (right side in the figure) and the standard value. The size can be grasped visually.

  In addition, in FIG. 10, the example which displays a physical condition evaluation result in the state which does not distinguish in an area | region is shown, and in FIG. 11, the example which displays the physical condition evaluation result using the area | region defined by the deviation degree from a standard value was shown. . FIG. 12 shows an example in which the standard value is clearly shown on the horizontal bar which is a one-dimensional map so that the direction and the size of the difference from the standard value can be understood. Thus, the display of the display screen of the smartphone possessed by the person to be evaluated 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 grasped visually.

  In addition, although the evaluation result of the evaluated person is shown by dots in FIGS. 10 and 12 and the position of the tip of the bar graph in FIG. 11, the physical condition evaluation result of the evaluated person can be visually viewed using either display form. Needless to say, it can be displayed by a method different from the method exemplified in each example.

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

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

  Moreover, as a display method of the physical condition evaluation result in the physical condition evaluation system according to the present embodiment, in addition to the index displayed using the two-dimensional or one-dimensional map described with reference to FIGS. It is possible to adopt a method of displaying as it is, a method of displaying the evaluation result rank (“normal”, “slightly caution”, “caution”) in characters. When displaying physical condition evaluation results without using these figures, by coloring the color surrounding the area where the numerical values and characters are displayed, based on the evaluation result rank, In the case where a state requiring attention is indicated in the physical condition evaluation result, it is preferable to be able to appeal to the evaluation person's vision more strongly.

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

  FIG. 13 is an example showing a transition of the physical condition evaluation value of the person to be evaluated with the passage of time. More specifically, the transition 141 from the start of work on the evaluation day of the evaluation subject's physical condition evaluation value is shown. In the example shown in FIG. 13, the morning physical condition evaluation value shown on the left side of the figure is an average. Especially in the afternoon, it is close to the numerical value ranked as “attention”, but in the afternoon, the physical condition evaluation value 141 becomes a value close to “normal” and continues until the dot 142 indicating the current time point. ing.

  Thus, by displaying the transition of the numerical value indicating the physical condition evaluation result of the evaluated person, the evaluated person can grasp his / her physical condition change. As shown in FIG. 13, there is no problem when the physical condition evaluation result is approaching a state that is ranked as “normal”, but conversely, when the evaluation result is approaching an area that is ranked as “attention”. It is necessary for the person being evaluated to be aware of changes in their physical condition.

  Note that FIG. 13 illustrates an example of the transition of the physical condition evaluation value, which is an overall index of the physical condition evaluation of the person to be evaluated, but the transition of the reference heart rate value and the heart rate response value, which are the reference for the physical condition evaluation, is illustrated. It is also possible to display them together, and it is also possible to display only the transition of the reference heart rate value and the heart rate response value without displaying the transition of the physical condition evaluation value.

  Moreover, as a display of the transition of the physical condition evaluation result, in addition to showing the transition according to the time of the evaluation day, for example, showing the transition of the physical condition evaluation result for each evaluation day of the latest one week, etc. Can be set to

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

  FIG. 14 shows an example of a display image on the administrator information terminal 31 used by the site supervisor 30 who is an administrator in the heat stroke risk management system equipped with the physical condition evaluation system of the present embodiment. As shown in FIG. 14, the site supervisor 30 displays 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 manager information terminal 31. The physical condition of can be easily grasped.

  In FIG. 14, as the physical condition evaluation result, “normal”, “slightly caution”, and “caution” are illustrated by ranks that are classified according to a difference from a predetermined standard value. The physical condition evaluation value can be expressed as a numerical value, and the reference heartbeat value and the heartbeat response value can be displayed in addition to the physical condition evaluation value or without displaying the physical condition evaluation value. In this case, the color of the displayed characters and numerical values, or the color of the corresponding frame or the entire column of the displayed table will vary depending on the evaluation result, and in particular, work that has been evaluated as being in a caution state. It is more preferable that the person stands out.

  The physical condition evaluation result list of the person to be evaluated shown in FIG. 14 can be displayed on the management computer 41 at the business office 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 field supervisor.

  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, the example which shows the list | wrist of the physical condition evaluation result of the worker 10 displayed on the manager information terminal 31 of the site supervisor 30 as a list was demonstrated. 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 list format. For example, the two-dimensional evaluation map shown in FIG. The physical condition evaluation result of the evaluator can be displayed with dots, and in this way, the on-site supervisor who is the administrator can grasp the overall tendency of the physical condition evaluation result of the worker to be managed. Moreover, it is also possible to display a name and management ID in the vicinity of the dot indicating the evaluation result of each person to be evaluated so that the worker can be identified.

  As described above, in the physical condition evaluation system according to the present embodiment, based on the heart rate data and acceleration data acquired by the biological information acquisition unit worn by the evaluator, the subject's reference heart rate value and heart rate The response value can be calculated and its physical condition can be evaluated. The physical condition evaluation result based on the reference heart rate value and the heart rate response value is displayed on the display screen, so that the person to be evaluated can visually grasp the physical condition evaluation result, and attention to the change in the physical condition is required. When it is evaluated, physical condition management can be performed by taking measures such as resting the body.

  In the embodiment described above, when the physical condition evaluation result is ranked according to the difference from the predetermined standard value, it is described that the physical condition evaluation result is divided into three ranks of “normal”, “slight attention”, and “caution”. . However, this rank division is merely an example, and it is possible to divide into two ranks or four or more ranks instead of three ranks, and the names of the respective ranks are limited to those that have been raised. It goes without saying that there is nothing.

  The physical condition evaluation system disclosed in the present application is installed together with a system for managing the risk of developing heat stroke of a worker who is working in a state where physical and thermal loads are large, such as construction sites and transportation industries. It is possible to evaluate the physical condition of a managed person under various circumstances. In addition, as a physical condition evaluation system disclosed in this application alone, it is used for a wide range of applications such as physical condition management of workers in construction sites and factories, physical condition management of residents in sports gyms and elderly facilities, physical condition management of athletes during training, etc. Therefore, it is useful as a physical condition management system that allows the person to be evaluated to visually understand his / her physical condition evaluation result.
