  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, configurations denoted by the same reference numerals indicate the same configurations, and the description thereof will be omitted.

  FIG. 1 is a block diagram showing a configuration of a display system 1 according to an embodiment of the present invention. FIG. 2 is a diagram showing a helmet 6 which is an example of a wearable device worn by a user U who is a user of the display system 1. FIG. 3 is a cross-sectional view, and FIG. 3 is a block diagram showing a specific configuration of the acquisition unit 2, the portable information terminal 3, and the like.

  The display system 1 according to the present embodiment detects, as an example of user information, which is information of the user U, data on biological information and environmental information on heat stroke, and on an example of analysis information calculated from the user information data. This is for calculating a determination result regarding heat stroke. That is, the display system 1 according to the present embodiment is used as a heat stroke risk calculation system, and by using the display system 1, the possibility of occurrence of heat stroke in the user U can be predicted. The display system 1 may be used for other purposes such as health management and state management of the user U in addition to calculating the risk of heat stroke by selecting user information or changing the calculation method of analysis information. Can be used.

  As shown in FIG. 1, the display system 1 can communicate with a helmet 6, which is an example of a wearable device worn by the user U, and a transmitter 4 included in the helmet 6, and a portable information terminal 3 carried by the user U. And a management server 5 such as a Web server connected to the portable information terminal 3 via a communication line 50 such as the Internet or an intranet. The helmet 6 includes the acquisition unit 2 which is various sensors for detecting user information as information of the user U, and uses the user information to prevent the user U from suffering from heat stroke. In the present embodiment, the acquisition unit 2 acquires data relating to biological information and environmental information as an example of user information. The transmitter 4 transmits the data acquired by the acquiring unit 2 to the portable information terminal 3. The management server 5 is connected to the client terminal 7 via a communication line 50. The client terminal 7 is, for example, an information device terminal of an administrator who manages each user U, and is a display terminal according to the present invention. Note that the configuration of the display system 1 is not limited to the above embodiment.

  The display system 1 according to the present invention includes an acquisition unit 2, a portable information terminal 3, a transmitter 4, a management unit 2, a management server 5, and an application program (management program) installed in the client terminal 7 and the like. It controls the server 5 and the client terminal 7 and performs a predetermined calculation. The management program is stored in a storage unit included in each component. In addition to downloading the management program via the Internet, the management program can be recorded on a computer-readable recording medium such as an optical disk, a DVD, an SD card, and a USB flash memory. The display system 1 does not need to have an application installed in all of the portable information terminal 3, the management server 5, the client terminal 7, and the like. For example, the display system 1 can be constructed by installing an application on the portable information terminal 3 and the management server 5 and accessing the management server 5 via the communication line 50 by the client terminal 7.

  The acquisition unit 2 includes a biological information acquisition unit 21 and an environment information acquisition unit 22, as shown in FIG. As shown in FIG. 2, the biological information acquiring unit 21 and the environmental information acquiring unit 22 are provided on a helmet 6 worn by a user U such as a worker who works in a factory, a construction site, a forest, or the like. Note that the biometric information acquisition unit 21 and the environment information acquisition unit 22 can be provided on another wearable device different from the helmet 6 (for example, a jacket or a belt worn by the user U).

  In the present embodiment, the biological information acquisition unit 21 is provided on the headband 61 of the helmet 6 and acquires the biological information of the user U at every predetermined measurement time. The biological information acquisition unit 21 in the present embodiment is a skin surface temperature sensor having an electrode that comes into contact with the user U, and acquires biological information on the temperature of the user U every minute.

  Note that the biological information acquisition unit 21 acquires a temperature such as a skin contact temperature or a body temperature at a location other than the place where the user U touches, and acquires various other information such as the pulse wave, brain wave, or blood flow of the user U. Alternatively, by combining them, it is also possible to use them as biological information. However, when the display system 1 is used for preventive management of heat stroke, a configuration in which the body temperature of the user U is acquired as biological information using a temperature sensor is preferable because of high correlation with the onset of heat stroke. In addition, for a worker who performs dangerous work, a skin surface temperature sensor is provided on a wearable device worn by the user U from a viewpoint of safety that there is no need to insert an instrument into the body and a viewpoint of easiness of measurement. It is more preferable to provide the temperature of the user U by providing it. In addition, from the viewpoint of measuring biological information in a portion near the brain where the influence of heat stroke is greatest, the configuration of measuring the skin contact temperature by providing a contact temperature sensor on the helmet 6 where the body temperature of the user U is provided is provided. preferable.

  Further, the predetermined measurement time interval may be other than one minute. However, at the site where the display system 1 is adopted, the break time is often several minutes to several tens of minutes, so that the predetermined measurement time interval is preferably set between 1 minute and 10 minutes. Note that the measurement time interval can be set smaller than 1 minute. For example, it is also possible to adopt a configuration in which measurement is always performed with a measurement time interval of 1 second. However, when the measurement is performed frequently as in the case of the constant measurement, the frequency of the measurement and the transmission increases, and the battery consumption increases. For this reason, in the present embodiment, the measurement time interval is set to one minute or more, so that the frequency of measurement and transmission is reduced as compared with the case where measurement is performed frequently, so that battery consumption is suppressed.

  In the present embodiment, as shown in FIGS. 2 and 3, the environment information acquisition unit 22 is housed in a housing member 40 that is detachably attached to the rear part of the helmet 6 or the headband 61 or the like. Is acquired at predetermined measurement times. The environment information acquisition unit 22 in the present embodiment includes a temperature sensor that acquires the outside air temperature every minute, a humidity sensor that acquires the outside humidity every minute, and the like.

  The environment information acquisition unit 22 calculates an approximate value of a WBGT index known as a heat index (hereinafter simply referred to as “WBGT”) every minute from the acquired outside temperature and outside humidity. . The WBGT index is an index obtained by taking into consideration the temperature, humidity, wind speed, and radiant heat of the magnitude of the thermal stress applied to the human body, and when this value is large, it is desirable to stop work or sports. It has been. In addition, the environment information acquisition unit 22 acquires insolation intensity, weather, illuminance, and the like in addition to the outside temperature and the outside humidity, acquires various information such as time and position information, or combines them to obtain an environment. It can also be used as information. However, from the viewpoint of simplicity of measurement, it is preferable that the environmental information is calculated based on the temperature and humidity around the user U.

  The transmitter 4 is a short-range wireless transmitter that transmits the data of the biological information and the environment information, which are the user information data acquired by the acquisition unit 2, to the portable information terminal 3 carried by the user U at every measurement time. And it is housed in the housing member 40 as shown in FIG. As the short-range wireless transmitter, for example, a wireless PAN defined by the Bluetooth (registered trademark) or ZigBee (registered trademark) standard, a wireless MAN defined by the WiMAX (registered trademark) standard, or the like is used. .

  As shown in FIG. 3, a battery 41 is housed in the housing member 40 in addition to the environment information acquisition unit 22 and the transmitter 4. The battery 41 supplies power to the terminal operation unit 30, the transmitter 4, and the like. As the battery 41, for example, various batteries including a disposable lithium battery, an alkaline battery, a rechargeable lithium battery, and the like can be used. In particular, as the battery 41 disposed on the helmet 6, a small button-type battery, a coin-type battery, or the like is suitably used because it is space-saving and lightweight.

  The transmitter 4 transmits the biometric information and the environmental information, which are the user information data of the user U acquired by the acquisition unit 2, to the portable information terminal 3 at every measurement time. The mobile information terminal 3 is configured by a smartphone, a tablet, a portable wireless device, a portable personal computer, or the like carried by each user U. In the present embodiment, the helmet 6 as a wearable device and the portable information terminal 3 are separately configured, but the portable information terminal 3 may be integrally configured with the wearable device. As shown in FIG. 3, the portable information terminal 3 includes a terminal operation unit 30, a transmitter 4 and a management server 5, a communication device 31 for transmitting and receiving biological information and environmental information data as user information data, a touch panel and the like. , And a terminal display unit 33 such as a liquid crystal display panel.

  As shown in FIG. 3, the terminal calculation unit 30 includes a user score calculation unit 301, a determination score calculation unit 302, and a determination unit 303, and each unit is a storage unit (such as a memory) (not shown) and a calculation unit (such as a CPU). ). Hereinafter, each unit will be specifically described.

  The user score calculation unit 301 includes the user information data received by the communication device 31, the biometric information of the user U acquired by the biometric information acquisition unit 21 (in this embodiment, the temperature that the user U wants), and the environmental information. Based on the environment information (WBGT around the user U in the present embodiment) acquired by the acquisition unit 22, the number of users is calculated for each measurement time (1 minute).

  Specifically, as shown in FIG. 4A, the storage unit of the user score calculation unit 301 is set in advance in accordance with the biological information data (the temperature that the user U wants) acquired by the biological information acquisition unit 21. (Hereinafter, referred to as “biological score”) are stored. Also, as shown in FIG. 4B, the storage unit of the user score calculation unit 301 stores a preset score (hereinafter, referred to as “WBGT”) corresponding to the environment information data (WBGT) acquired by the environment information acquisition unit 22. Environmental score) is stored. Then, the calculation unit of the user score calculation unit 301 adds the biometric score corresponding to the received biometric information data and the environmental score corresponding to the received environment information data, thereby calculating the user score for each measurement time. Is calculated.

  For example, when the temperature of the user U acquired by the biometric information acquisition unit 21 is 36 ° C., the biometric score is 6, as shown in FIG. When the WBGT acquired by the environment information acquiring unit 22 is 29 ° C., the environmental score is 5, as shown in FIG. In this case, the user score is 6 + 5 = 11.

  In the display system 1 according to the present embodiment, the user score calculation unit 301 is set so as to calculate the user score higher as the values of the biometric information and the environment information are farther from the preset values. More specifically, as shown in FIG. 4A, the storage unit of the user score calculation unit 301 is set so that the biometric score increases as the biometric information data (the temperature to be measured) increases. In the present embodiment, the set value of the biological information data is set to 30 ° C. Further, as shown in FIG. 4B, the storage unit of the user score calculation unit 301 is set so that the environment score increases as the environment information data (WBGT) increases. In the present embodiment, the set value of the environment information data is set to 10 ° C.

  In the present embodiment, the user score is calculated by the sum of the living body score and the environmental score, but the method of calculating the user score is not limited to this. For example, the user score can be calculated by a method using only one of the biometric score and the environmental score, and a method of substituting the biometric score and the environmental score into a predetermined arithmetic expression.

  The judgment score calculation unit 302 accumulates values calculated from the user score calculated by the user score calculation unit 301 and a time coefficient set for each elapsed time from the present to the past, and accumulates a value of the analysis information. An example determination point is calculated for each measurement time.

  Specifically, as shown in FIG. 4C, the storage unit of the determination score calculating unit 302 stores a coefficient (hereinafter, referred to as a “time coefficient”) corresponding to an elapsed time that is retroactive from the present to the past. Is stored. Then, in the calculation unit of the determination point calculation unit 302, the determination point is calculated for each measurement time by accumulating the product of the user score calculated by the user score calculation unit 301 and the time coefficient set for each elapsed time. It is calculated.

  For example, when both the living body score and the environmental score are the highest value of 12 in all of the past 240 minutes, the user score is always 24. Therefore, the maximum value of the theoretical determination points is 24 × 0.5 × 60 minutes + 24 × 1.0 × 60 minutes + 24 × 1.5 × 60 minutes + 24 × 2.0 × 60 minutes = 7200.

  In the display system 1 according to the present embodiment, the time coefficient used in the determination point calculation unit 302 is set so that the elapsed time becomes smaller as it goes back in the past. More specifically, as shown in FIG. 4C, if the elapsed time is less than 60 minutes, the time coefficient is set to 2.0 in the storage unit of the determination score calculating unit 302, and similarly, if the elapsed time is less than 120 minutes. It is set to be 1.0 for less than 1.5 and 180 minutes, 0.5 for less than 240 minutes, and 0 for more than 240 minutes.

  In the present embodiment, the determination score, which is the analysis information, is calculated as the cumulative value of the product of the user score and the time coefficient, but the method of calculating the determination score is not limited to this. For example, it is also possible to calculate the judgment score by accumulating the values obtained by substituting the user score and the time coefficient into a predetermined arithmetic expression.

  The determination unit 303 determines whether or not the determination score calculated by the determination score calculation unit 302 exceeds a preset threshold. Specifically, if the judgment point is less than the threshold, it is determined as “safe”, and if the judgment point is equal to or more than the threshold, it is judged as “dangerous”. In the present embodiment, the first threshold value and the second threshold value are set to 4000 and 5000, respectively, and if the judgment point is less than the first threshold value (less than 4000), it is “safe”, and the judgment point is If the value is equal to or more than the threshold value and less than the second threshold value (4000 or more and less than 5000), it is determined to be "Caution", and if the score is equal to or more than the second threshold value (5000 or more), it is determined to be "Dangerous".

  As shown in FIG. 1, the communication device 31 of the portable information terminal 3 has a two-way communication function of exchanging data with the management server 5 via the communication line 50. In addition, on the terminal display unit 33 of the portable information terminal 3, the determination score calculated by the determination score calculation unit 302 and the determination result determined by the determination unit 303 are displayed. Note that the terminal display unit 33 may be configured to display only one of the determination score and the determination result.

  More specifically, as shown in FIGS. 7A and 7B, the judgment score, which is the analysis information, is displayed on the judgment score display section 33a of the terminal display section 33, and the judgment score is represented by a bar graph on the terminal display section. The result is displayed on the graph display unit 33b in 33, and the result of the determination in the determination unit 303 is displayed as a symbol and characters on the determination result display unit 33c in the terminal display unit 33. In the present embodiment, “〇” is displayed when the determination result is “safe”, “△” is displayed when the result is “caution”, and “x” is displayed when the result is “danger”. The display method on the terminal display unit 33 may be, as described above, in addition to numerical values, bar graphs, symbols, and characters, as well as pie charts, images such as icons representing human expressions and dangers, and the like. good. Further, the terminal display unit 33 may be configured to notify a manager or a family using a warning sound, a warning light, an e-mail notification, or the like.

  When displaying various types of information on the terminal display unit 33, if the display colors on the display units 33a to 33c are changed from green to yellow and red in accordance with the degree of danger of the user U, the user U It is possible to effectively notify the degree of danger.

  From the portable information terminal 3 to the management server 5, biometric information and environment information data, which are user information data received from the transmitter 4 of the helmet 6, are transmitted via the communication device 31 and the communication line 50. As shown in FIG. 1, the management server 5 includes a management calculation unit 500 and a watching control unit 51 which is a control unit according to the present invention, and each unit is a storage unit (memory and the like) and a calculation unit (CPU and the like, not shown). ). As shown in FIG. 1, the watching controller 51 of the management server 5 can communicate with the helmet 6 via the communication line 50.

  In the present embodiment, the management calculation unit 500 has the same function as the terminal calculation unit 30 in the portable information terminal 3. More specifically, as shown in FIG. 1, the management calculation unit 500 includes a user score calculation unit 501, a determination score calculation unit 502, and a determination unit 503.

  The user score calculation unit 501 receives the biological information of the user U (in this embodiment, the temperature that the user U wants to receive) and the environment information (the WBGT around the user U in this embodiment) received from the transmitter 4. , The number of users is calculated for each measurement time (1 minute).

  Specifically, similarly to the user score calculation unit 301 in the terminal calculation unit 30, the storage unit of the user score calculation unit 501 stores a score set in advance corresponding to the biological information data (the temperature that the user U wants to hit). (Hereinafter, referred to as “biological score”) (see FIG. 4A). In addition, the storage unit of the user score calculation unit 501 stores a score (hereinafter, referred to as “environment score”) set in advance corresponding to the environment information data (WBGT) (FIG. 4B). )). Then, the calculation unit of the user score calculation unit 501 adds the biometric score corresponding to the received biometric information data and the environmental score corresponding to the received environmental information data, thereby calculating the user score for each measurement time. Is calculated.

  The determination score calculation unit 502 accumulates values calculated from the user score calculated by the user score calculation unit 501 and a time coefficient set for each elapsed time that is retroactive from the present to the past. An example determination point is calculated for each measurement time.

  Specifically, similarly to the judgment point calculation unit 302 in the terminal operation unit 30, the storage unit of the judgment point calculation unit 502 stores a coefficient (hereinafter, referred to as “coefficient”) corresponding to the elapsed time that is retroactive from the present to the past. (Referred to as "time coefficient") (see FIG. 4C). Then, in the calculation unit of the determination score calculation unit 502, the determination score is calculated for each measurement time by accumulating the product of the user score calculated by the user score calculation unit 501 and the time coefficient set for each elapsed time. It is calculated.

  Note that, in the present embodiment, the determination points are calculated by the same method in the terminal calculation unit 30 and the management calculation unit 500. However, the processes for calculating the determination points may not be exactly the same. good. That is, it is also possible to adopt a configuration in which the determination score, which is the analysis information, is calculated by a different method, for example, the calculation order in the middle is changed.

  The determination unit 503 determines whether or not the determination score calculated by the determination score calculation unit 502 exceeds a preset threshold value, similarly to the determination score calculation unit 303 in the terminal calculation unit 30. Specifically, if the judgment point is less than the threshold, it is determined as “safe”, and if the judgment point is equal to or more than the threshold, it is judged as “dangerous”. In the present embodiment, the first threshold value and the second threshold value are set to 4000 and 5000, respectively, and if the judgment point is less than the first threshold value (less than 4000), it is “safe”, and the judgment point is If the value is equal to or more than the threshold value and less than the second threshold value (4000 or more and less than 5000), it is determined to be "Caution", and if the score is equal to or more than the second threshold value (5000 or more), it is determined to be "Dangerous". The biological information and environmental information data, which is user information data received from the portable information terminal 3 of each user U, and the determination score and the determination result, which are analysis information calculated based on the user information data, are monitored and controlled. This is recorded in the storage unit of the unit 51.

  In the storage unit of the watching control unit 51, a user map UM is recorded in advance as user data in which each user U is classified. In the user map UM, as shown in FIG. In the column M, the number Mn of the portable information terminal 3 carried by each user U is recorded. The name Un of each user U is recorded in the name column N of the user map UM. In FIG. 8, for convenience, the name Un of the user U is described as "user U (number)".

  In the present embodiment, the user map UM records three types of categories: a first category, a second category, and a third category. Specifically, as shown in FIG. 8, for the first category “business unit name”, a plurality of first attributes, “business headquarters”, “manufacturing business unit”,. The business unit name P1 is recorded. Similarly, as for the second category "department name", in the department name column C2, there are a plurality of second attributes provided for each business division, "legal department", "first manufacturing department", and so on. Are recorded. Similarly, for the third category “section name”, in the section name column C3, a plurality of third attributes provided for each copy, such as “intellectual property section”, “manufacturing section 3”, and so on. Is recorded.

  For example, in the user map UM shown in FIG. 8, the name of the user U who carries the portable information terminal 3 of “terminal number 1” is “user U161”. It records that the second category belongs to the Legal Department and the third category belongs to the Intellectual Property Department. That is, in the user map UM, all the users U are classified into any one of a plurality of attributes in each of the above categories. Note that, in the present embodiment, a case will be described in which three types of categories of “division name”, “department name”, and “section name” are recorded in the user map UM, but the number of categories is one, Two or four or more types may be used. Further, the number of attributes classified in each category is not limited. It is also possible to adopt a category other than the affiliation, such as the company to which the user U belongs, or the post, gender, age, weight, etc., as the category. When the company to which the user U belongs is used as the category, the analysis information can be used for a credit check of the company. It is also possible to adopt a configuration in which the user U is classified into two or more of a plurality of attributes. That is, the user U may be of any type as long as the user U is classified into at least one of a plurality of attributes.

  In the storage unit of the watching control unit 51, attributes of each category are recorded in advance as a category map. Specifically, as shown in FIG. 9A, the “business unit name” which is the first category is recorded as a business unit map MC0. The business unit map MC0 includes the business unit No. as four attributes. “Business Headquarters (Pn1)”, “Manufacturing Business Department (Pn2)”, “Management Business Department (Pn3)”, and “Sales Business Department (Pn4)” are recorded as 1-4.

  In addition, a department map is also recorded for each business division for the “category name” which is the second category. For example, as shown in FIG. 9B, in the manufacturing division map MC2 relating to the manufacturing division Pn2, the division No. As “21 to 23”, “first manufacturing unit (Pn21)”, “second manufacturing unit (Pn22)”, and “third manufacturing unit (Pn23)” are respectively recorded. A division map is similarly recorded for other divisions.

  In addition, a section map is also recorded for each section for the third category “section name”. For example, as shown in FIG. 9C, in the first manufacturing department map MC21 relating to the first manufacturing department Pn21, the section No. “Manufacturing first section (Pn211)”, “manufacturing second section (Pn212)”, “manufacturing third section (Pn213)”, and “manufacturing fourth section (Pn214)” are recorded as 211 to 214, respectively.

  As described above, as shown in FIGS. 10 to 12, the watching control unit 51 executes the display control for totalizing and displaying the analysis information for one selected category for each attribute based on the user data. . As a result, the analysis information obtained by analyzing the user information can be compared and analyzed at predetermined time intervals for the attribute of the user U. In the present embodiment, by using the user information and the analysis information as information relating to heat stroke, the possibility of heat stroke of the user U can be compared and analyzed for each attribute of the user. Specifically, in each category (division, division, or section), at what date and time, and for any attribute (individual division, division, or division), analysis information (in this embodiment, heat stroke risk level) ) Can be compared and analyzed to see if there is a large number of people with high numbers. It should be noted that a plurality of selection display sections may be displayed to select a plurality of categories.

  In the present embodiment, the “business division name”, the “department name”, and the “section name” to which the user U belongs are adopted as the first category, the second category, and the third category. ing. Thus, the analysis information can be compared and analyzed for each affiliation which is the attribute of the user U.

  In the present embodiment, biometric information of the user U and environmental information around the user U are adopted as user information. Thus, the possibility of heat stroke of the user U can be compared and analyzed for each attribute (affiliation) of the user U.

  In addition, the watching control unit 51 tallies the number of users U for each attribute (in the present embodiment, the number of members belonging to each attribute) as a parameter based on the user data, and The display control for performing the batch display on the display unit NM is executed. This makes it possible to compare and analyze the tendency of the analysis information (such as the ratio of the dangerous person to the number of members belonging) for each attribute of the user U.

  In addition, the watching control unit 51 can also execute display control in which the number of operating portable information terminals 3 is totaled as a parameter and displayed collectively on the operating personnel display unit NR. This makes it possible to compare and analyze the actual tendency of the analysis information (the ratio of the dangerous person to the number of operators, etc.) for each attribute of the user U. As described above, in the present embodiment, display control is performed in which the number of users U and the number of operating portable information terminals 3 are totaled and displayed collectively as parameters. This makes it possible to compare and analyze more practical trends in the analysis information for each attribute of the user U.

And execute display control for batch display. This makes it possible to analyze the correlation between the date and the category with respect to the analysis information.

  In addition, as described above, in response to access from the client terminal 7, the watching control unit 51 summarizes the analysis information for each of the selected categories based on the user data and displays the analysis information on the management display unit 71. The display control for collectively displaying on the screen 71a is executed. Thereby, even from a place remote from the management server 5, the administrator can confirm the management data including the analysis information, and perform the analysis by comparing each attribute of the user.

  In the watching control unit 51, at least one of the management data including information such as the biological information of the user U, the environment information, the determination score calculated by the determination score calculation unit 502, and the determination result determined by the determination unit 503 is: The information is acquired for each user U and stored in the storage unit. In this manner, in the display system 1, by collecting and storing both real-time information and past information, it is possible to use the display system 1 in accordance with the usage scene of the user. For example, by comparing past heat stroke data with real-time data, it is possible to estimate the incidence of accidents due to heat stroke and to estimate changes in work efficiency.

  Note that the watching control unit 51 may be configured to display the acquired management data on a display unit such as a Web screen. In addition, the watching control unit 51 may be configured to display at least one of the acquired management data such as the biological information of the user U and the environmental information on the management display unit 71 or the like.

  Further, when at least one of the determination unit 303 and the determination unit 503 determines that the determination score for one user U exceeds the threshold, the transmitter 4 transmits the information through the portable information terminal 3 and the communication line 50, It is also possible to adopt a configuration in which the above determination result is transmitted to the client terminal 7 of the administrator. Thus, when the risk of heat stroke increases for the user U, the administrator can immediately recognize the risk.

  The watching control unit 51 is provided when a client registered in advance, for example, a client terminal 7 such as a personal computer owned by the company to which the user U belongs is connected to the management server 5 via the communication line 50. Is provided to the client terminal 7.

Also, the judgment points are displayed in the judgment gauge display section PG or in a color gradation. Further, the management data (judgment result) of the user U generated by the watching control unit 51 is displayed by not only characters but also symbols on the judgment result display unit JR. As a result, it is possible to intuitively grasp the point at which the specific user U is dangerous. Furthermore, by changing the color of the display in the judgment result display part JR, the judgment gauge display part PG, and the judgment result display part JR of the individual result display part 74r from green to yellow and red according to the degree of danger, It can also be expressed so that the degree of danger can be grasped intuitively.

  As an example of a management method performed in the display system 1 configured as described above, a heat stroke risk calculation method will be specifically described using the first embodiment data shown in FIG. The data of the present embodiment relates to the user U1 as an example, and FIG. 7A illustrates the portable information terminal 3 of the user U.

  First, the living body information acquiring unit 21 acquires, every minute, a temperature of the user U, which is the living body information of the user U measured by the helmet 6 worn by the user U (biological information acquiring step, step in FIG. 5). S01). In this embodiment, for convenience of explanation, as shown in FIG. 6A, it is assumed that the temperature to be applied within the past 60 minutes is constant at 36 ° C. Then, similarly, 37 ° C. in the past 60 minutes or more and less than 120 minutes, 37 ° C. in the past 120 minutes or more but less than 180 minutes, 36 ° C. in the past 180 minutes or more and less than 240 minutes, and 36 ° C. in the time zone of the past 240 minutes or more It is assumed that certain data has been acquired in.

  In parallel with the biological information acquisition step, the environment information acquisition unit 22 acquires a WBGT, which is environment information around the user U, every minute (environment information acquisition step, step S02 in FIG. 5). In this embodiment, for convenience of explanation, it is assumed that the WBGT within the past 60 minutes is constant at 28 ° C. as shown in FIG. Then, similarly, 33 ° C. in the past 60 minutes or more and less than 120 minutes, 32 ° C. in the past 120 minutes or more and less than 180 minutes, 31 ° C. in the past 180 minutes or more and less than 240 minutes, and 29 ° C. in the time zone after the past 240 minutes or more. It is assumed that certain WBGT data has been acquired.

  Next, in the user score calculation units 301 and 501, the user score is calculated every minute based on the temperature and the WBGT (user score calculation process, step S03 in FIG. 5). More specifically, as shown in FIG. 6A, the user score is obtained by adding the biometric score corresponding to the temperature that is the biometric information data and the environmental score corresponding to the WBGT that is the environmental information data. Calculated for each measurement time. In the present embodiment, the number of users within the past 60 minutes is 10 per minute, and similarly, 14 in the past 60 minutes to less than 120 minutes, 13 in the past 120 minutes to less than 180 minutes, and 180 in the past 180 minutes to 240 minutes. The value is 12 when the time is less than minute, and 11 when the time is 240 minutes or more.

  Next, in the judgment point calculation units 302 and 502, the judgment points are calculated every minute by accumulating the values calculated from the user points and the time coefficient set for each elapsed time from the present to the past. It is calculated (determination point calculation step, step S04 in FIG. 5). Specifically, the product of the user score calculated by the user score calculation unit 301 and the time coefficient set for each elapsed time is accumulated. In the present embodiment, the time coefficient of the elapsed time of less than 60 minutes is set to 2.0, and similarly 1.5 for less than 120 minutes, 1.0 for less than 180 minutes, 0.5, 240 for less than 240 minutes. It is set to be 0 in minutes or more. For this reason, as shown in FIG. 6A, the product of the number of users per minute and the time coefficient in each time zone is 20 within the past 60 minutes, 21 from the past 60 minutes to less than 120 minutes, and the past 120 minutes or more. The value is 13 when the period is less than 180 minutes, 6 when the period is 180 minutes or more and less than 240 minutes, and is 0 when the period is 240 minutes or more. Then, the cumulative value for 60 minutes in each time zone is 1200, 1260, 780, 360, and 0 in this order, so that the total judgment score is 3600.

  Next, the determination units 303 and 503 determine whether or not the determination points calculated by the determination point calculation units 302 and 502 exceed a preset threshold value (heat stroke risk determination step, step S05 in FIG. 5). ). Specifically, if the number of judgment points is less than the first threshold value (less than 4000), it is "safe". If the number of judgment points is more than the first threshold value and less than the second threshold value (more than 4000 and less than 5000), "Caution" If the number of determination points is equal to or greater than the second threshold (5000 or more), it is determined to be "dangerous." In the present embodiment, since the number of determination points is 3600, the determination units 303 and 503 determine “safe”.

  Next, the determination score and the determination result are displayed on the terminal display unit 33 of the portable information terminal 3 and the management display unit 71 of the client terminal 7 (a determination result display step, step S06 in FIG. 5). Specifically, as shown in the column of the user U1 in FIG. 7A, the judgment score "3600" is displayed on the judgment score display section 33a, and the judgment score is displayed as a bar graph on the graph display section 33b, and the judgment result display is performed. The determination result is displayed in the section 33c with the symbol “〇” and the character “safe”.

  Next, data of the second embodiment shown in FIG. 6B will be described. This example data relates to a user U, which is another example, and FIG. 7B illustrates the portable information terminal 3A of the user U. Note that the determination procedure in the following example data is the same as that in the above-described first example data, and therefore, detailed procedures such as various data calculation methods will not be described.

  In the biological information acquisition step in the present embodiment, as shown in FIG. 6B, it is assumed that the temperature to be applied within the past 60 minutes has been constant at 39 ° C. Then, similarly, 39 ° C. in the past 60 minutes or more and less than 120 minutes, 38 ° C. in the past 120 minutes or more and less than 180 minutes, 36 ° C. in the past 180 minutes or more and less than 240 minutes, and 36 ° C. in the time zone of the past 240 minutes or more It is assumed that certain data has been acquired in. That is, in the present embodiment, it is assumed that the temperature to be drawn tends to increase from the past to the present.

  In the environment information acquiring step, it is assumed that the WBGT within the past 60 minutes has been constant at 38 ° C. as shown in FIG. 6B. Then, similarly, 37 ° C. in the past 60 minutes or more and less than 120 minutes, 35 ° C. in the past 120 minutes or more but less than 180 minutes, 31 ° C. in the past 180 minutes or more and less than 240 minutes, and 29 ° C. in the time zone after the past 240 minutes or more It is assumed that certain WBGT data has been acquired. That is, in the present embodiment, it is assumed that the WBGT tends to increase from the past to the present.

  Next, in the user score calculation step, as shown in FIG. 6B, the number of users within the past 60 minutes is 18 per minute. The value is 16 for minutes or more and less than 180 minutes, 12 for 180 minutes or more and less than 240 minutes, and 11 for a time zone where the past 240 minutes or more have elapsed.

The value is 6 when the time is less than minute, and becomes 0 when the time period has passed 240 minutes or more. Then, the cumulative value for 60 minutes in each time zone is 2160, 1620, 960, 360, and 0 in this order, and the total judgment score is 5100.

  Next, in the heat stroke risk determination step, the determination point of this embodiment is 5100, so that the determination unit 303 determines “danger”.

  Next, in the display step, in the terminal display section 33 of the portable information terminal 3 and the management display section 71 of the client terminal 7, as shown in the column of the user U3 in FIG. The judgment point "5100" is displayed, the judgment point is displayed as a bar graph on the graph display section 33b, and the judgment result is displayed on the judgment result display section 33c as a symbol "x" and the character "danger".

  Next, the third embodiment data shown in FIG. 6C will be described. The present embodiment data relates to a user U different from the first embodiment and the second embodiment. The data of the present embodiment is obtained by reversing the time series of the data of the second embodiment. That is, in the data of the second embodiment, the temperature and the WBGT tend to increase from the past to the present, whereas in the data of the embodiment, the temperature and the WBGT tend to decrease from the past to the present. Shall be.

  In the biological information acquisition step in the present embodiment, as shown in FIG. 6C, it is assumed that the temperature within the past 60 minutes has been constant at 36 ° C. Then, similarly, 36 ° C. in the past 60 minutes or more and less than 120 minutes, 38 ° C. in the past 120 minutes or more and less than 180 minutes, 39 ° C. in the past 180 minutes or more and less than 240 minutes, and 39 ° C. in the time zone of the past 240 minutes or more It is assumed that certain data has been acquired in. That is, in the present embodiment, it is assumed that the temperature to be drawn tends to decrease from the past to the present.

  In the environment information acquiring step, it is assumed that the WBGT within the past 60 minutes has been constant at 29 ° C. as shown in FIG. 6C. Then, similarly, 31 ° C. in the past 60 minutes or more and less than 120 minutes, 35 ° C. in the past 120 minutes or more but less than 180 minutes, 37 ° C. in the past 180 minutes or more and less than 240 minutes, and 38 ° C. in the time zone of the past 240 minutes or more It is assumed that certain WBGT data has been acquired. That is, in the present embodiment, it is assumed that the WBGT has a downward trend from the past to the present.

  Next, in the user score calculation step, as shown in FIG. 6C, the user score within the past 60 minutes is 11 per minute, and similarly, 12 in the past 60 minutes or more and less than 120 minutes, and 120 in the past. The value is 16 for minutes or more and less than 180 minutes, 18 for 180 minutes or more and less than 240 minutes, and 18 for a time period of 240 minutes or more.

It is provided with judgment point calculation units 302 and 502 for calculating judgment points, which are analysis information, for each measurement time by accumulating values calculated from the time coefficients.

  As described above, in the display system 1, since information data is not transmitted from the management server 5 to the portable information terminal 3, the data communication amount can be suppressed as compared with the bidirectional communication system. Further, according to the display system 1, the mobile information terminal 3 calculates the judgment score and displays it on the terminal display unit 33. Therefore, the display system 1 compares the judgment score calculated by the management server and displays it on the terminal display unit. Thus, the time required from the acquisition of the user information to the display of the score on the terminal display unit 33 can be shortened, and the time lag can be reduced.

  Further, according to the display system 1, since the mobile information terminal 3 calculates the judgment score and displays it on the terminal display unit 33, even if a failure occurs in the management server 5 or the communication line 50, the judgment is made on the terminal display unit 33. The score can be displayed. In addition, according to the display system 1, the management server 5 can store data relating to the user information by recording the biometric information and the environment information as the user information and the determination score as the analysis information in the storage unit. .

  Further, in the display system 1, the user information transmitted from the portable information terminal 3 to the management server 5 is the biometric information and the environment information of the user U, and includes the determination score, which is the analysis information calculated by the terminal calculation unit 30, and the like. Absent. As described above, since the analysis information whose data amount is larger than the user information is not transmitted from the mobile information terminal 3 to the management server 5, the communication between the mobile information terminal 3 and the management server 5 via the communication line 50 is not performed. It is possible to suppress the amount of data to be communicated with the device.

  In the display system 1, the user score calculation units 301 and 501 are set so that the user score is calculated to be higher as the values of the biological information and the environment information are farther from the preset values. As a result, the higher the biometric information and environmental information, the higher the user score is calculated, and the risk of heat stroke can be calculated appropriately.

  Further, in the display system 1, the time coefficient used in the determination point calculation units 302 and 502 is set so that the elapsed time goes back in the past and becomes smaller. This makes it possible for the display system 1 to appropriately calculate the risk of heat stroke. That is, by increasing the time coefficient of the most recent past information within the predetermined calculation time, the importance is determined to be greater than the information having a certain time elapsed within the predetermined calculation time.

  That is, in the present embodiment, since the size of the latest user score is regarded as important, even when the total value of the user scores is the same as in the second example and the third example, as in the second example. If the user score is on the rise, it is determined to be dangerous, and if the user score is on the decline as in the third embodiment, it is determined to be safe. That is, in the case where the risk of heat stroke is higher than when the user score is constant, such as when the user score is rising, it is possible to reduce the possibility of underestimating the risk. it can. Conversely, to reduce the possibility of overestimating the risk in cases where the risk of heat stroke is lower than when the user score is constant, such as when the user score is falling. Can be.

  As described above, according to the display system 1 according to the present embodiment, the risk of heat stroke can be comprehensively determined in consideration of the cumulative time of exposure to high temperatures, the risk reduction due to the elapsed time, and the like. That is, the display system 1 can more appropriately calculate the risk of heat stroke as compared with a configuration in which a determination is made based only on a real-time measurement value or simply a value obtained by accumulating information within a calculation time. It is.

  In the display system 1 according to the present embodiment, the user score calculation units 301 and 501 are configured to set the user score to a minus value when the biological information data and the environment information data are close to preset values. Is set. Specifically, as shown in FIG. 4A, the storage unit of the user score calculation unit 301 stores the biological information data (the temperature to be sought) of less than 32 ° C., the biological score of −6, and the biological score of −32 ° C. to less than 33 ° C. The living body score is set to -3. As shown in FIG. 4B, the storage unit of the user score calculation unit 301 stores the environment information data (WBGT) at a temperature of less than 17 ° C., the environmental score is −6, and the environmental score is 17 ° C. or more and less than 19 ° C. −4, the environment score is set to −2 at 19 ° C. or higher and lower than 21 ° C. As described above, when the biological information data and the environment information data are close to the set values, it is determined that the user U has performed cooling or rest of the body, and the user score is reduced. The time coefficient can be arbitrarily set by a manager who manages the user U using the display system 1 (for example, a manager of a company that employs the user U).

  Further, in the display system 1 according to the present embodiment, the time coefficient used in the determination score calculation units 302 and 502 is set to be 0 when the elapsed time exceeds a predetermined time of 240 minutes. This makes it possible to more appropriately calculate the risk of heat stroke by not considering the influence of past information after a predetermined time has elapsed. In the present embodiment, since the work is performed every four hours at the construction site or the like, the predetermined time is set to 240 minutes. However, the predetermined time can be set to another numerical value.

  In the display system 1, the environment information acquisition unit 22 can be provided not at the helmet 6 but at the portable information terminal 3 used by the user U or a work site. It is also possible to adopt a configuration in which the management server 5 acquires information on the Web as environment information. Further, by configuring the portable information terminal 3 integrally with the helmet 6, the terminal calculation unit 30 including the user score calculation unit 301, the determination score calculation unit 302, and the determination unit 303 is provided in the housing member 40. It is also possible.
