Description

  The present invention relates to a thermal index measuring device and a control method for the thermal index measuring device.

  When various activities such as sports and mowing are performed under high temperature and humidity, there is a risk that the activist will suffer from heat stroke. As a device for preventing such danger, Patent Documents 1 to 4 include a sensor that measures the temperature and relative humidity, and determines whether the measured temperature and relative humidity are at risk of causing heat stroke. However, when it is determined that there is a danger, a device is disclosed that warns an activist to that effect. In particular, the device disclosed in Patent Document 4 is a device that can be worn on the wrist of an activator.

(First embodiment)
The thermal index measuring apparatus 1 according to the first embodiment of the present invention measures a thermal index such as a heat index and a WBGT value, and notifies a preventive measure against heat stroke in a living body according to the thermal index. It has the function to do. In the description of the present embodiment, the case where the thermal index measurement device 1 is used for a human being (biological person) will be described as an example. Therefore, this thermal index measuring device 1 is configured in a size and form that allows a user (actor) to wear and act like a wristwatch, for example. Therefore, the user can wear the heat index measuring device 1 on the arm and perform various activities such as various sports and mowing, and the user can take heat stroke prevention measures according to the heat index of the environment in which he is active. Can be easily known. Hereinafter, a specific configuration of the heat index measuring apparatus 1 will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a circuit block diagram showing an electrical circuit configuration of the thermal index measuring device 1. FIG. 2 is an external view showing the configuration of the external appearance of the heat indicator measuring device 1, and FIGS. 2A, 2B, 2C, and 2D are respectively a plan view of the heat indicator measuring device 1, It is a bottom view, a left side view, and a front view.

  As shown in FIG. 1, the thermal index measuring device 1 includes a temperature sensor 2 as temperature measuring means, a humidity sensor 3 as humidity detecting means, a temperature sensor 2 and a detection unit 4 of the humidity sensor 3, and a temperature sensor 2. And a calculation circuit 5 as a thermal index calculation means for calculating a thermal index and a WBGT value based on an output signal from the humidity sensor 3, and a switch for inputting various instructions and information to the thermal index measuring device 1 Unit 6, a control IC 7 for controlling various operations of the thermal indicator measurement device 1, a liquid crystal display device 8 as a notification means, a piezoelectric buzzer 9 as a notification means, and a power source 10 constituted by a lithium battery or the like have.

  Further, as shown in FIG. 2, the heat index measuring apparatus 1 has a casing 11 as a holding unit, and the casing 11 is shown in FIG. 1 in addition to the temperature sensor 2 and the humidity sensor 3 described above. The constituent members of the thermal index measuring device 1 are held. The casing 11 is a flat rectangular parallelepiped as a whole, and band attaching portions 12 are provided at both ends in the longitudinal direction, and the heat index measuring device 1 is provided by a band 13 as an attaching means attached to the band attaching portion 12. Can be worn on the wrist. Note that the casing 11 is, for example, 4 cm long (longitudinal direction), 3 cm wide (short direction) 3 cm thick so that even if the user wears it on the wrist, the activity is not hindered. The size is 1 cm.

  Among the components shown in FIG. 1, the display unit 14 (see FIG. 2) of the liquid crystal display device 8, the switch unit 6, the temperature sensor 2, and the detection unit 4 of the humidity sensor 3 face the outside of the housing 11. It is incorporated in the housing 11. That is, the display unit 14 of the liquid crystal display device 8 is disposed so as to face the upper surface, which is one of the pair of wide surfaces in the flat direction of the housing 11. The detection unit 4 is disposed on the upper surface of the housing 11 between the periphery of the display unit 14 and the outer periphery of the housing 11. Further, on the pair of side surfaces 15R and 15L that are disposed along the flat direction of the casing 11 and along the longitudinal direction of the casing 11, four switches 6A, 6B, 6C, Two 6Ds are disposed on each of the side surfaces 15R and 15L. Switches 6A and 6B are disposed on the side surface 15R, and switches 6C and 6D are disposed on the side surface 15L.

  For example, a band gap temperature sensor is used as the temperature sensor 2. The humidity sensor 3 uses, for example, a capacitance type relative humidity sensor so as to detect the relative humidity as the humidity. In the present embodiment, the temperature sensor 2 and the humidity sensor 3 are integrated on a single chip, and the temperature and relative humidity of the air in contact with the detection unit 4 can be measured by one detection unit 4. Has been. When the user wears the thermal index measurement device 1 on the wrist, the display unit 14 faces upward (on the opposite side to the skin) so that the display unit 14 of the liquid crystal display device 8 can be seen. To be attached). Therefore, when the thermal index measuring device 1 is worn on the wrist, the detection unit 4 is arranged on the front side, that is, on the upper side with the thermal index measuring device 1 sandwiched between the human body. That is, the detection part 4 is arrange | positioned in the position which is hard to receive to the influence of a user's body temperature or sweat. Therefore, the temperature sensor 2 and the humidity sensor 3 can measure the temperature and the relative humidity in a state where the influence of moisture by the user's body temperature and sweat is small.

Signals related to the temperature and relative humidity output from the temperature sensor 2 and the humidity sensor 3 are amplified by the amplification circuits 16 and 17 and then input to the arithmetic circuit 5. The arithmetic circuit 5 calculates two heat indexes, an approximate value of a heat index and a WBGT value (hereinafter referred to as a WBGT approximate value), based on the detected temperature and relative humidity. The thermal index is a value calculated by the following calculation formula (1) proposed by the Australian Federal Bureau of Weights and Measures based on temperature and relative humidity, and is an index representing how hot a person feels.

Thermal index = Ta + 0.33 × E−0.70 × ws−4.00 (1)

E = (Rh / 100) × 6.105 × exp {17.27 × Ta / (237.7 + Ta)}

Ta = temperature (℃)
Rh = relative humidity (%)
ws = wind speed (m / s where 10 m is the height. Note that the heat index measuring device 1 according to the present embodiment calculates 0 m / s)

On the other hand, the approximate value of WBGT is also calculated from the temperature and relative humidity based on the following calculation formula (2) proposed by the Australian Federal Metrology Bureau.

WBGT approximate value = 0.567 × Ta + 0.393 × E + 3.94 (2)

E = (Rh / 100) × 6.105 × exp {17.27 × Ta / (237.7
+ Ta)}

Ta = temperature (℃)
Rh = relative humidity (%)

The WBGT value is a value calculated by the following calculation formula (3) based on the air temperature (dry bulb temperature), the wet bulb temperature, and the black bulb temperature (radiant heat).

WBGT value = 0.7 × (wet bulb temperature) + 0.2 × (black bulb temperature) +0.1 (dry bulb temperature) (3)

  The WBGT value is an index for determining the degree of risk associated with behavior in an extremely hot environment. The calculation of the WBGT value requires three measurement values of the air temperature, the wet bulb temperature, and the black bulb temperature, and a means for measuring these three measurement values is required, resulting in a large measuring device. Therefore, the above-described calculation formula (2) has been proposed by the Federal Bureau of Weights and Measures, which can easily calculate a WBGT approximate value that approximates the WBGT value from two measured values of temperature and relative humidity. The approximate value of WBGT is a value that is not related to the temperature of the black sphere, and can be obtained from measured values that can be measured relatively easily such as the ambient temperature and relative humidity of the user. Therefore, when the WBGT approximate value is obtained as the thermal index as in the thermal index measuring apparatus 1 of the present embodiment, it is not necessary to provide a means for measuring the black sphere temperature, and the temperature sensor 2 and the relative humidity The WBGT approximate value can be obtained as a heat index with a simple configuration including the sensor 3.

  The control IC 7 includes an input port 18, a memory 19, a ROM 20 (Read Only Memory), a CPU 21 (Central Processing Unit), a RAM 22 (Random Access Memory), an output port 23, and the like. The temperature sensor 2 and the humidity sensor 3 are connected to the input port 18 via the arithmetic circuit 5, and the switches 6A to 6D are further connected. Further, the liquid crystal display device 8 is connected to the output port 23 via the display drive circuit 24, and the piezoelectric buzzer 9 is connected via the buzzer drive circuit 25.

  Signals from the switches 6A to 6D and signals related to the heat index (heat index and WBGT approximate value) output from the arithmetic circuit 5 are input to the input port 18, and information related to the heat index and input from the switches 6A to 6D The information is stored in the memory 19.

  The ROM 20 stores a table (1) shown in FIG. 3 and a table (2) shown in FIG. 4 as a data table (hereinafter referred to as a notification content data table), and the ROM 20 functions as a notification content storage means. In Tables (1) and (2), notification contents for instructing the user to take preventive measures for heat stroke corresponding to the approximate value of WBGT and the exercise level are defined. Table (1) corresponds to a user with strong physical strength, and Table (2) corresponds to a user with weak physical strength. In this embodiment, in each table, the exercise levels are “slow exercise (maximum oxygen consumption 50 to 70%)”, “medium exercise (maximum oxygen consumption 50 to 90%)”, “violent exercise”. (Maximum oxygen consumption 75 to 100%) ”, and the WBGT approximate value as a degree of risk of heat stroke, 5 levels from 1 to 5 (hereinafter, this level is referred to as WBGT level). ). That is, in Tables (1) and (2), the notification content for instructing the user as a heat stroke prevention measure is defined according to the WBGT level and the exercise level. Therefore, by specifying the WBGT approximate value and the exercise level in the table (1) or the table (2), it is possible to specify a preventive measure against heat stroke corresponding to the designated WBGT approximate value and the exercise level.

  The heat index measuring device 1 is configured to notify the user of heat stroke prevention measures by the liquid crystal display device 8 and the piezoelectric buzzer 9. Therefore, the notification contents include an instruction message to the user for display on the liquid crystal display device 8, a sound generation pattern of the piezoelectric buzzer 9 to be sounded in conjunction with the display of the instruction message, display of the instruction message and sound of the buzzer sound. And the length of time during which the instruction message is displayed and the buzzer is sounded.

  For example, in Table (1), when the exercise level is a moderate exercise and the WBGT approximate value is “1”, the notification content is liquid crystal of hydration (“Drink”, see FIG. 8B). A display on the display device 8 and a continuous buzzer sound generated by the piezoelectric buzzer 9 performed in conjunction with the display, and the display and the sound generation are performed simultaneously at a timing of 20 minutes for 20 seconds. It has become.

  Similarly, in Table (1), when the exercise level is a gentle exercise and the approximate value of WBGT is “3”, the notification content at this time is hydration performed for 20 seconds at a timing of every 20 minutes. In addition to the display on the liquid crystal display device 8 ("DLINK", see FIG. 8C) and the continuous buzzer sound generated by the piezoelectric buzzer 9 performed in conjunction with this display, timing every 30 minutes The display on the liquid crystal display device 8 of a break (for example, “REST-20”, see FIG. 8D) performed for 20 seconds, and the sound generation of a short buzzer sound in the piezoelectric buzzer 9 performed in conjunction with this display It has become.

  Furthermore, in Table (1), when the exercise level is a moderate exercise and the WBGT approximate value is “5”, the notification content at this time is the exercise stop (“DANGER”, see FIG. 8E). ) On the liquid crystal display device 8 and the continuous buzzer sound generated by the piezoelectric buzzer 9 performed in conjunction with this display.

  As described above, Table (1) corresponds to a user with strong physical strength, and Table (2) corresponds to a user with weak physical strength. In other words, it is preferable that a user with weak physical strength is allowed to take a heat stroke prevention measure of the same content with a lower WBGT approximate value than a user with strong physical strength. Therefore, the table (2) of the present embodiment is set to the approximate value of WBGT, which is lower in the preventive measures against heat stroke with the same content as compared with the table (1). Specifically, for example, the preventive measure taken at the WBGT level “5” at the exercise level “slow exercise” in Table (1) is the preventive measure at the WBGT level “4” in Table (2). .

  The CPU 21 controls various operations of the thermal index measuring device 1 in addition to driving the liquid crystal display device 8 and the piezoelectric buzzer 9. The CPU 21 also functions as notification content determination means. That is, the CPU 21 stores in the RAM 22 the WBGT approximate value stored in the memory 19, the information input by the switches 6 </ b> A to 6 </ b> D, and the notification content data table (table (1) or (2)) stored in the ROM 20. The notification content corresponding to the information read from the read WBGT and the switches 6A to 6D is determined from the notification content data table. In accordance with the determined notification content, the CPU 21 displays a predetermined instruction message on the liquid crystal display device 8 and causes the piezoelectric buzzer 9 to generate a buzzer sound having a predetermined sound generation pattern.

  Next, the usage method of the heat | fever parameter | index measuring apparatus 1 is demonstrated, referring FIG. 5 and FIG. FIG. 5 is a flowchart of the operation setting of the heat index measuring device 1, and FIG. 6 shows the contents of the display screen of the liquid crystal display device 8 in each step of the flowchart shown in FIG.

  The heat index measurement device 1 of the present embodiment functions as a wristwatch and a stopwatch with a configuration that omits the description, in addition to the functions as a heat index measurement device such as the above-described heat index measurement and notification of heat stroke prevention measures. It is comprised so that it may have the function of. The switch 6D is a switch for selecting the above three functions. Each time the switch 6D is pressed, the CPU 21 sets the operation mode of the thermal index measuring device 1 as a thermal index measuring mode that functions as a thermal index measuring device, a wristwatch mode that can be used as a wristwatch, and a stopwatch. Change to a timekeeping mode that can be used cyclically. Here, the operation when the heat index measurement mode is selected as the operation mode of the heat index measurement apparatus 1 and the heat index measurement apparatus 1 functions as the heat index measurement apparatus will be described.

  When the heat index measurement mode is selected by the switch 6D, the heat index measurement device 1 is in the initial state (step S10) when functioning as the heat index measurement device. In this initial state (step S10), the liquid crystal display device 8 displays an initial screen 26 shown in FIG. “SPORTS” in the display 27 on the initial screen 26 is a display indicating that the mode of the thermal index measuring device 1 is the thermal index measuring mode. The display 28 is a display indicating whether the table (1) or the table (2) is read into the RAM 22, and “HIGH” is displayed when the table (1) is read. When the table (2) is read, “LOW” is displayed on the display 28.

  The display 29 is a display that indicates which exercise level is specified to specify the preventive measure when the CPU 21 specifies the preventive measure against heat stroke based on the table (1) or the table (2). When the exercise level is “slow exercise”, the display shown in FIG. 7A is performed. When the exercise level is “medium exercise”, the display shown in FIG. 7B is performed. In the case of “violent exercise”, the display shown in FIG. 7C is performed. In the initial state (step S10), as a default operation, the CPU 21 reads the data of Table (1) into the RAM 22 and designates the exercise level as “slow exercise”. Accordingly, on the initial screen 26, as shown in FIG. 6A, “HIGH” is displayed on the display 28, and the display 29 of FIG. 7A is displayed on the display 29.

  When the thermal index measurement mode is selected by the switch 6D, the thermal index measuring device 1 starts measuring the WBGT approximate value and the thermal index. Then, the numerical value of the WGBT level in Table (1) corresponding to the measured WBGT approximate value is displayed as a display 30. That is, the CPU 21 determines the WGBT level of the table (1) corresponding to the measured WBGT approximate value based on the measured WBGT approximate value and the table (1) read into the RAM 22 by default, and this WGBT level. Is displayed as a display 30. This display 30 allows the user to know numerically the risk of suffering from heat stroke in the current situation. The measured heat index is displayed as a display 31. This display 31 allows the user to know the heat index. The display 32 is a timer display described later.

  Every time the switch 6A is pressed from the above-described initial state (step S10), the operation setting mode shown in steps S20, S30, S40, and S50 is sequentially shifted. Then, predetermined operation settings described later are performed in each operation setting mode.

  When the switch 6A is pressed once in the initial state (step S10), the table selection mode is selected to select which notification content data table of the table (1) or (2) is read into the RAM 22 (step S20). In the table selection mode (step S20), the liquid crystal display device 8 displays a table selection screen 33 shown in FIG. In the table selection mode (step S20), the notification content data table (tables (1) and (2)) to be read into the RAM 22 can be selected by the switch 6B. On the table selection screen 33, each time the switch 6B is pressed, the display 34 (“FIT / HIGT”) shown in FIG. 6B and the display 35 (“FIT / LOW”) shown in FIG. 8B alternate. Is displayed. When the display 34 is displayed, the notification content data table of the table (1) is read into the RAM 22, and when the display 35 is displayed, the notification content data of the table (2) is displayed in the RAM 22. The table is being read. As described above, Table (1) shows the contents of countermeasures for people with strong physical strength, and Table (2) shows the contents of countermeasures for people with weak physical strength. That is, the user presses the switch 6B and selects the notification content data table (tables (1) and (2)) to input user data indicating whether the user's physical strength is strong or weak. That is, the switch 6B functions as a biometric (user) data input means, and the user reads the notification content data table corresponding to either the table (1) or the table (2) into the RAM 22 according to his / her physical strength. Instructs the CPU 21. Here, the notification content data tables (tables (1) and (2)) correspond to the strength of the user's physical strength, but the notification content corresponding to the type of user such as an elderly person, a child, or an athlete. You may make it hold | maintain a data table for every kind of user.

  After selecting the notification content data table (table (1) or table (2)) (step S20), pressing the switch 6A once confirms the selection (step S20) and sets the exercise level. The setting mode (step S30) is entered. In this exercise level setting mode (step S30), the exercise level setting screen 36 shown in FIG. In the exercise level setting screen 36, each time the switch 6B is pressed, the display 37 (“FIT / HIGT / LIGHT”) and the display 38 (“FIT / HIG”) shown in FIGS. 6D, 6E, and 6F, respectively. HIGH / MIDIUM ") and display 39 (" FIT / HIGT / HARD ") are cyclically displayed. When the table (2) is selected as the notification content data table in step S20, the display 40 (“FIT” shown in FIGS. 6G, 6H, and 6I is displayed in the exercise level setting mode (step S30). / LOW / LIGHT "), display 41 (" FIT / LOW / MIDIUM "), and display 42 (" FIT / LOW / HARD ") are cyclically displayed. In this exercise level setting mode (step S30), by pressing the switch 6B as described above, the exercise levels (“slow exercise”, “medium” in the notification content data tables (tables (1) and (2)) are selected. "Exercise exercise", "Exercise exercise") can be selected. When the displays 37 and 40 are displayed, “slow movement” is selected. When the displays 38 and 41 are displayed, “medium movement” is selected, and the displays 39 and 42 are displayed. When displayed, “Intense Exercise” is selected. In this way, when the user presses the switch 6B and selects an exercise level ("gentle exercise", "medium exercise", "severe exercise"), the user is going to perform an exercise that he or she is about to perform or is currently performing The exercise level of the current exercise is input as user data. That is, the switch 6B functions as a living body (user) data input means, and the user inputs the exercise level of the exercise that he or she is going to perform from now on to the heat indicator measuring device 1 from the switch 6B.

  When the exercise level is set and then the switch 6A is pressed once, the exercise level selection (step S30) is confirmed and the timer time method setting mode (step S40) for setting the timer time method is entered. In the timer timing method setting mode (step S40), the timer timing method setting screen 43 shown in FIG. 6 (J) is displayed on the liquid crystal display device 8. Then, a time measured by a timer mechanism (not shown) is displayed. The timer timing method can be selected from a subtraction type (countdown) and an addition type (elapsed time counting). Each time the switch 6B is pressed, a display 44 ("COUNTDOWN") shown in FIG. Display 45 (“ELAPSED TIME”) shown in FIG. 6K is alternately displayed. When the display 44 is displayed, the subtraction mode is selected, and when the display 45 is displayed, the addition mode is selected. The timer timing method setting screen 43 displays a display 28 corresponding to the selection contents in the table selection mode (step S20) and a display 29 corresponding to the selection contents in the exercise level setting mode (step S30). .

  When the switch 6A is pressed once after setting the timer counting method described above, the timer timing method selection (step S40) is confirmed, and the thermal index measuring device 1 operates in steps S20 to S40. The process proceeds to a preventive measure notification mode (step S50) in which an operation for notifying a preventive measure against heat stroke is executed according to the setting.

  Here, for example, in step S20, the table (1) intended for a user having strong physical strength is selected, and in step S30, “slow exercise” is selected as the exercise level. Assuming that the addition formula is selected as the timekeeping method, the notification operation of the preventive measure for heat stroke of the heat index measuring apparatus 1 will be described. In the preventive measure notification mode (step S50), as shown in FIG. 8A, the preventive measure notification screen 47 having a display area 46 in which an instruction message corresponding to the content of the preventive measure is displayed on the liquid crystal display device 8. Is displayed.

  In the preventive measure notification mode (step S50), the CPU 21 determines which WBGT level in Table (1) corresponds to the measured WBGT approximate value, and performs notification according to the notification content at the WBGT level. For example, when the temperature measured by the temperature sensor 2 is 24 ° C. and the relative humidity measured by the humidity sensor 3 is 25%, the thermal index calculation means 5 calculates the approximate WBGT value as about 20 ° C. The CPU 21 determines that the calculated WBGT level of the approximate WBGT value is “1” based on the table (1). Here, since the exercise level set in step S30 is “slow exercise”, the notification content when the WBGT level in the table (1) is “1” is displayed together with the hydration message display and this message display. Both the continuous single buzzer sounds are generated every 20 minutes for 20 seconds. That is, as shown in FIG. 8B, the CPU 21 displays a display 48 (“Drink”), which is a message for instructing the user to supply water, at the position of the display area 46 shown in FIG. This is repeated for 20 seconds every minute, and a continuous single buzzer sound is generated for 20 seconds every 20 minutes in accordance with the display timing and display time of the display 48.

  By viewing the display 48 displayed on the liquid crystal display device 8, the user can know that hydration is necessary as a heat stroke prevention measure. In addition, since the piezoelectric buzzer 9 is sounded in conjunction with the display 48, the user can know that the instruction message is displayed by the buzzer sound, and thus the oversight of the instruction message can be prevented. The CPU 21 is configured to stop the buzzer sound when both the switch 6A and the switch 6C are pressed. That is, until the user recognizes that the heat stroke countermeasure has been notified and presses the switch 6A and the switch 6C to stop the buzzer sound, the CPU 21 causes the piezoelectric buzzer 9 to continue sounding. In other words, the buzzer sound can be continued until the user recognizes that the preventive measure has been notified, and the user can be surely recognized the preventive measure notification. Note that a display 49 shown in FIG. 9 is displayed in the display area 46 until the display 48 is displayed. This display 49 is a display that repeatedly moves from left to right, and this display allows the user to know that the heat indicator measuring device 1 is operating in the preventive measure notification mode. In the display 50 which is a timer display, the time since the start of time measurement is displayed. The user can know the time until hydration from the display 50.

  For example, when the temperature measured by the temperature sensor 2 is 27 ° C. and the relative humidity measured by the humidity sensor 3 is 50%, the thermal index calculation means 5 calculates the approximate value of WBGT as about 26 ° C. The CPU 21 determines that the calculated WBGT level of the approximate WBGT value is “3” based on the table (1). Here, as described above, since the exercise level set in step S30 is “slow exercise”, the notification content when the WBGT level in the table (1) is “3” includes the hydration message display and this message display. In addition to the continuous buzzer sound, which is performed in conjunction with the sound, the sound is generated every 20 minutes for 20 seconds, and both the break acquisition message display and the short buzzer sound generated in conjunction with this message display are both performed for 30 minutes. Every 20 seconds. That is, as shown in FIG. 8C, the CPU 21 displays a display 51 (“Drink”), which is a message for instructing the user to supply water, at the position of the display area 46 shown in FIG. While repeating for 20 seconds every minute, in addition to the display timing and display time of the display 51, the piezoelectric buzzer 9 is caused to generate a continuous single buzzer sound every 20 minutes for 20 seconds.

  Further, as shown in FIG. 8D, the CPU 21 displays a message 52 (“REST−”) instructing the user to take a break for a predetermined time at the position of the display area 46 shown in FIG. 20 ") is repeated every 30 minutes for 20 seconds, and a short buzzer sound is generated for 20 seconds every 20 minutes in accordance with the display timing and display time of the display 52. Note that “20” in the display 52 means the length of the break time, and here, “20” is displayed in the sense of 20 minutes. By displaying the break time in this way, the user can be prompted to take the displayed break time. Therefore, it is possible to prompt the user to take this necessary break time by displaying the break time as a break time necessary for preventing heat stroke. Although the break time is displayed as “20” here, an appropriate time is displayed as a break time necessary to prevent heat stroke.

  By seeing the display 51 and the display 52 displayed on the liquid crystal display device 8, the user knows that hydration is necessary as a heat stroke prevention measure and that it is necessary to take a break in addition to this. Can do. In addition, since the piezoelectric buzzer 9 is sounded together with the display 51 and the display 52, the user's instruction message can be prevented from being overlooked. Further, since the sound pattern of the buzzer sound is changed between the contents of the instruction message, that is, the display 51 (“DLINK”) and the display 52 (“REST-20”), the user can also prevent the contents of the preventive measures by the buzzer sound. Can know. The buzzer sound can be stopped by pressing both the switch 6A and the switch 6C.

  In addition, when notification of hydration performed every 20 minutes and notification of break acquisition performed every 30 minutes are performed at the same time, a message display (“REST” instructing break acquisition is given prior to hydration notification. -20 ") and a buzzer sound may be generated (a short sound for 20 seconds). Alternatively, a message display (“Drink”) for instructing hydration and a message display (“REST-20”) for instructing to acquire a break are alternately performed, and a buzzer sound is acquired as a continuous short sound or a break for notification of hydration. One of the short tones that are notifications may be pronounced.

  Further, for example, when the temperature measured by the temperature sensor 2 is 31 ° C. and the relative humidity measured by the humidity sensor 3 is 70%, the thermal index calculation means 5 calculates the approximate WBGT value as about 34 ° C. The The CPU 21 determines that the calculated WBGT level of the approximate WBGT value is “5” based on the table (1). Here, since the exercise level set in step S30 is “slow exercise”, the notification contents when the WBGT level is “5” in Table (1) are the exercise / work stop message and the continuous buzzer sound. It is to pronounce. As shown in FIG. 8E, the CPU 21 displays a display 53 (“DANGER”), which is a message instructing the user to stop exercise / activity, at the position of the display area 46 shown in FIG. Do. In addition to the display 53, the piezoelectric buzzer 9 generates a continuous buzzer sound. By viewing the display 53 displayed on the liquid crystal display device 8, the user can know that it is necessary to stop the exercise or work being performed as a heat stroke prevention measure. Moreover, since the piezoelectric buzzer 9 is sounded in conjunction with the display 53, it is possible to prevent the user from overlooking the message. The display 53, which is an exercise / work stop message, and the sounding of the buzzer sound associated therewith are immediately performed when the WBGT level of the WBGT approximate value is determined to be “5”. Therefore, the user can immediately know that it is dangerous to continue exercise / work in the environment. Note that the buzzer sound at this time is set to a louder volume than the buzzer sound used when instructing hydration or a break, so that the user can be surely notified that the current situation is in a dangerous state. The display 53 and the continuous buzzer sound of the piezoelectric buzzer 9 are continuously generated until both the switch 6A and the switch 6C are pressed.

  As described above, in the heat indicator measurement device 1, the user selects an appropriate notification content data table (table (1) or table (2)) according to the physical strength of the user in step S20, and step S30. By selecting an exercise level that matches the level of exercise performed by the user, the user can be notified of appropriate preventive measures against heat stroke according to the measured WBGT approximate value.

  That is, the magnitude of the risk of developing heat stroke during exercise varies greatly depending on the level of exercise performed by the user and the strength of the user's physical strength. The difference in the risk of developing heat stroke during exercise due to differences in the level of exercise performed by the user and the strength of the user's physical strength is dependent on individual differences such as age differences in the risk of developing heat stroke in daily life. Much larger than the difference due to. Therefore, in order to effectively prevent the onset of heat stroke during exercise, it is necessary to accurately grasp the difference between the exercise level performed by the user and the strength of the user's physical strength, and the exercise level performed by the user and the strength of the user's physical strength. It is necessary to take preventive measures according to the situation. For this reason, the user data for determining the notification content includes data on the level of exercise performed by the user and the strength of the user's physical strength, so that the notification content indicating heat stroke prevention measures during exercise can be It can be suitable for the prevention of heat stroke at times.

  In the present embodiment, the notification content includes a specific instruction message for preventing heat stroke, a buzzer sound generation pattern that is sounded in conjunction with the display of the instruction message, and the instruction message and buzzer sound. The timing of sound generation and the length of time during which the instruction message display and buzzer sound are generated are set, but only the instruction message display is set to be performed at a predetermined time for a predetermined time. Also good. Note that the notification contents shown in this embodiment are exemplary, and the contents of the instruction message, the timing of displaying the instruction message, the timing of generating the buzzer sound, etc. are the physical strength of the user, the WBGT level, and the exercise. Depending on the level, each is set to appropriately prevent heat stroke.

  The calculation of the WBGT approximate value is performed based on an average temperature and an average relative humidity for a predetermined time, for example, 2 minutes. In this way, by calculating the WBGT approximate value based on the average temperature and the average relative humidity for a predetermined time, it is possible to notify a countermeasure corresponding to the actual environment (temperature, relative humidity) around the user. . On the other hand, if the notification content is determined based on the real-time WBGT approximate value, for example, when direct sunlight hits the detection unit 4 instantaneously and the detected temperature instantaneously increases, Although the actual temperature is not high, the WBGT approximate value is calculated at a high temperature. Also, for example, when working with food jars in a well-ventilated room, the location where the hood is working is high relative humidity with water vapor, but the relative humidity is not so high in other locations. It becomes. In such an environment, when the user spends only a little time working on the paddle and the other time is working in a place where the relative humidity is not high, the time for the user to work under high relative humidity (boil processing) The time spent on work is short, so there is little risk of getting heat stroke. However, if the notification content is judged based on the real-time WBGT approximate value, even in such a case, the WBGT approximate value is calculated on the basis of the measured relative humidity for only a short time engaged in the battering work. End up. As a result, there arises a problem that appropriate preventive measures are not notified to the user, such as a measure to stop exercise / work is notified where originally a preventive measure for hydration is sufficient. As described above, by calculating the WBGT approximate value based on the average temperature and the average relative humidity for a predetermined time, the occurrence of the above problem can be eliminated. The average temperature and the average relative humidity may be based on the measurement result of a predetermined time, or may be an average value of the temperature and the relative humidity measured a predetermined number of times at a predetermined time interval.

  When the user changes or the exercise level performed by the user changes, the operation setting is changed back to steps S20 and S30. By continuously pressing the switch 6D for 2 seconds, the thermal index measuring device 1 returns to the initial state (step S10) and can newly set the operation. When the switch 6D is pressed in the initial state (step S10), each time the switch 6D is pressed, the operation mode of the thermal index measurement device 1 is cyclically changed to the clock mode, the stopwatch mode, and the thermal index measurement mode.

  The contents of Tables (1) and (2), that is, the WBGT level, the exercise level, and the notification contents are examples, and these can be set as appropriate. For example, the heat stroke prevention described in the “Health Disease Prevention Guidebook during Sports Activities” issued on April 26, 1999 by the Japan Physical Education Association (revised on June 30, 2006) The content of notification for prevention of heat stroke may be determined corresponding to the WBGT level and the exercise level with reference to the exercise guidelines for the exercise.

  The thermal index measurement device 1 described above is an embodiment of the present invention. As another embodiment, for example, the thermal index measurement device 1 measures biological data such as a user's body temperature, pulse or blood pressure as measurement user data. Notification to prevent heat stroke from three viewpoints of WBGT approximate value, exercise level, and biological data, instead of the notification content data table of Tables (1) and (2). You may provide the notification content data table which can specify the content. By comprising in this way, the notification content for the heat stroke prevention based on the biometric data of the user output from a biometric sensor can be notified to a user. When the thermal index measurement device 1 includes a biosensor, the thermal index measurement device 1 is disposed on the bottom side of the thermal index measurement device 1, that is, on the surface facing the front side surface on which the detection unit 4 is disposed. When the apparatus 1 is worn on the wrist, the biosensor can be brought into close contact with the user's skin, and the biometric data of the user can be acquired accurately. In addition to measuring biometric data with a biometric sensor, the user may input the biometric data into the heat index measuring apparatus 1 himself / herself.

  Further, although the thermal index measuring device 1 has been described as a wristwatch-shaped configuration that is worn on the wrist, for example, a pendant configuration may be provided from the neck. In addition to the liquid crystal display device 8 and the piezoelectric buzzer 9, any one of the notification means may be provided. Moreover, it is good also as a structure which uses a vibration motor as a notification means, performs notification by vibration, or emits the content of notification as a voice instead of the sound of the piezoelectric buzzer 9.

  As the notification content storage means for storing the notification content data table, a replaceable memory such as an SD memory card may be used instead of the ROM 20. In this case, a notification content data table of contents corresponding to the types of users such as athletes, elderly people, children, etc., work in the coal mine, work in the bathroom, marathon, soccer, etc. is stored. By preparing the prepared SD memory card in advance, a wide and appropriate notification of heat stroke prevention can be performed according to the type of user and the activity content. Further, the ROM 20 may be a rewritable ROM, and a notification content data table or the like may be taken in from another device (for example, a personal computer) by wireless / wired communication.

(Second Embodiment)
The notification content defined in the notification content data table (table (1), table (2)) in the heat index measuring apparatus 1 described above is the second of the present invention described below with reference to FIGS. Like the thermal index measurement device 1 according to the embodiment, the liquid crystal display device 8 that is a notification means using the preventive measure notification program that is a program for controlling the operation of the liquid crystal display device 8 and the piezoelectric buzzer 9 and You may make it notify from the piezoelectric buzzer 9. FIG. In addition, about the control method of the heat | fever parameter | index measuring apparatus 1, it shall be demonstrated together with operation | movement of the heat | fever parameter | index measuring apparatus 1. FIG.

  The preventive measure notification program is stored in the ROM 20 that functions as a storage unit. Then, based on the preventive measure notification program, the CPU 21 controls the operations of the liquid crystal display device 8 and the piezoelectric buzzer 9. That is, the CPU 21 functions as a notification unit control unit.

  In the thermal index measuring apparatus 1 described as the second embodiment, the preventive measure notification program is stored in the ROM 20, and the CPU 21 uses the liquid crystal display device 8 and the piezoelectric buzzer 9 based on the preventive measure notification program. The configuration is the same as that of the thermal index measurement device 1 according to the first embodiment except that the operation is controlled. That is, as shown in the flowchart of FIG. 5, the thermal index measurement device 1 described as the second embodiment is the type of the notification content data table (table (1) or table (2) in the table selection mode (step S20). )) Is selected, and the exercise level setting mode is selected in the exercise level setting mode (step S30), the selected notification content data table and the exercise level are measured in the preventive measure notification mode (step S50). The preventive measure notification program is executed based on the WBGT level determined from the WBGT approximate value. That is, when the CPU 21 obtains the notification content data table type selected in the table selection mode (step S20) and the exercise level set in the exercise level setting mode (step S30), the preventive measure is taken. In the notification mode (step 50), the CPU 21 controls the operations of the liquid crystal display device 8 and the piezoelectric buzzer 9 based on the preventive measure notification program. By this control, the liquid crystal display device 8 and the piezoelectric buzzer 9 notify the user of heat stroke prevention measures.

  The operation of the liquid crystal display device 8 and the piezoelectric buzzer 9 according to the preventive measure notification program will be described with reference to FIGS.

  The preventive measure notification program includes a program A that executes the process of the flowchart A shown in FIG. 10, a program B that executes the process of the flowchart B shown in FIG. 11, and a program C that executes the process of the flowchart C shown in FIG. Have. In the preventive measure notification mode (step 50), the program A that executes the process of the flowchart A, the program B that executes the process of the flowchart B, and the program C that executes the process of the flowchart C are executed.

  The process shown in the flowchart A (hereinafter referred to as “flow A”) is for controlling the overall operation of the liquid crystal display device 8 and the piezoelectric buzzer 9. On the other hand, the process shown in the flowchart B (hereinafter referred to as flow B) and the process shown in the flowchart C (hereinafter referred to as flow C) control specific operations of the liquid crystal display device 8 and the piezoelectric buzzer 9. belongs to.

  That is, in the flow B, the liquid crystal display device 8 and the piezoelectric buzzer 9 can be used to give instructions to the user for hydration and a break so that the user can continue exercise and activities safely. This is for controlling the operation of the display device 8 and the piezoelectric buzzer 9 (see FIG. 11). The flow C informs the user that it is dangerous to continue the exercise / activity, and the liquid crystal display device 8 and the piezoelectric buzzer 9 can instruct the user to stop the exercise / activity. This is for controlling the operation of the display device 8 and the piezoelectric buzzer 9 (see FIG. 12).

  First, the processing content of the flow A (program A) will be described with reference to FIG.

  In the flow A, first, the temperature and humidity are measured, the WBGT approximate value is calculated based on the measured temperature and humidity, and the CPU 21 determines the WBGT level of the calculated WBGT approximate value (step). S110). The WBGT level is stored in the RAM 22 (step S120), and the flow B shown in FIG. 11 described later or the flow C shown in FIG. 12 described later is executed according to the WBGT level (step S130). The relationship between the approximate WBGT value and the WBGT level is the same as that shown in the notification content data table (1) shown in FIG. 5 or the notification content data table (2) shown in FIG.

  For example, the notification content data table (1) is selected in the table selection mode (step S20), and a moderate exercise is selected in the exercise level setting mode (step S30), and the WBGT level is “1”. "Is within the range of" 3 ", the execution of the process of flow B is started in step S130. On the other hand, for example, when the notification content data table (1) is selected in the table selection mode (step S20) and the middle level exercise is selected in the exercise level setting mode (step S30), the WBGT level is In the case of “4” or more, the process of flow C is executed.

  When the process of flow B is executed (No in step S132), the process of flow A is executed in parallel. In other words, while the flow B is being executed, the processing from step S140 to step S200 of the flow A described later is being executed. On the other hand, when the process of flow C is executed (Yes in step S132), the process of flow A is terminated (step S135).

  In the flow C (program C), as shown in FIG. 12, a process for instructing the user that it is dangerous to continue the exercise / activity and instructing the user to stop the exercise / activity is executed. (Step S500). Specifically, as shown in FIG. 8, the display 53 (“DANGER”) is displayed on the liquid crystal display device 8, and at the same time, the piezoelectric buzzer 9 generates a continuous buzzer sound. Then, both the switch 6A and the switch 6C are pressed, and it is determined whether or not the operation of stopping the display of the display 53 and the continuous buzzer sound of the piezoelectric buzzer 9 has been performed (step S510). The display 53 (“DANGER”) on the liquid crystal display device 8 and the continuous sound of the piezoelectric buzzer 9 are continuously generated (No in step S510). When the stop operation is performed (Yes in step S510), the process (S500) for instructing to stop the exercise / activity is ended, and the flow C is ended.

  Flow C is a process for causing the user to stop exercise / activity. Therefore, after the process of flow C is executed, it is necessary to prevent the user from instructing hydration or resting on the premise of continuation of exercise / activity. Therefore, when the flow C is executed, the processing of the flow A is ended (step S135).

  When both the switch 6A and the switch 6C are pressed, the display 53 and the buzzer sound of the continuous sound of the piezoelectric buzzer 9 are stopped (Yes in step S510), and after the process of the flow C is completed, a time is left. There are cases where the temperature, humidity, etc. are suitable for exercise / activity, and the user wants to resume exercise / activity. In this case, the switch 6D is pressed to set the operation mode of the heat index measuring device 1 to the heat index measurement mode, and then a predetermined operation setting is performed in the operation setting mode (step S10 to step S40), thereby preventing preventive measures. The mode (step S50) can be executed.

  On the other hand, when the process of the flow B is executed in step S130, the flow A starts measuring a measurement interval timer which is a timer for controlling the time interval of the measurement of the WBGT approximate value (step S140). This measurement interval timer is functionally realized in the CPU 21.

  The measurement interval timer measures a predetermined time, for example, 5 minutes (step S150). When the measurement interval timer measures 5 minutes (Yes in step S150), the WBGT approximate value is calculated again, and the WBGT level is determined based on the calculated WBGT approximate value (step S160). It is determined whether the determined WBGT level has changed with respect to the WBGT level stored in the RAM 22 in step S120 (step S170). The change in the WBGT level is performed by the CPU 21. That is, the CPU 21 also functions as a heat index change determination unit.

  In the present embodiment, the CPU 21 determines the presence or absence of a predetermined change in the heat index as the presence or absence of a change in the WBGT level defined in the notification content data table tables (1) and (2). The WBGT level is not limited to those specified in the notification content data table (1) and (2), but the range (numerical range) of the heat index corresponding to each level is narrowed or widened. Also good. Further, when the WBGT level changes in two or more steps, it may be determined that there is a predetermined change in the WBGT level. Furthermore, in this embodiment, the CPU 21 determines the change of the WBGT level over time at intervals of 5 minutes. However, the CPU 21 is not limited to this time interval, and may be a shorter time interval or a longer time interval. Good. By shortening the time interval, it is possible to effectively prevent heat stroke according to changes in the WBGT level.

  If it is determined in step S170 that the WBGT level has changed (Yes in step S170), the WBGT level after the change is stored in the RAM 22 in place of the previously stored WBGT level in step S120 (step S120). Step S180). In step S180, the time after the start of time measurement of a hydration timer (step S305) and a break timer (step S405) in the flow B described later is also stored. In addition, the time after starting the time measurement of the hydration timer and break timer memorize | stored here is in the flow B already performed. Subsequently, execution of flow B or flow C is selected according to the changed WBGT level (step S190). If the flow B is selected in step S190, the flow B that has already been executed is terminated, and the processing of the flow B based on the changed WBGT level is executed again.

  After execution of the process of flow B (step S190) is started, or when it is determined in step S170 that the WBGT level has not changed (No in step S170), the measurement interval timer is reset (step S200). After that, the measurement interval timer starts again (step S140), and the processing from step S150 to step S200 is repeated. That is, the flow A is executed in parallel with the execution of the flow B executed in step S130 or step S190. On the other hand, when the flow C is selected in step S190, the currently executed flow B is terminated and the process of the flow C is executed. When the process of the flow C is executed (Yes in step S192), the process of the flow A is finished so that the user is not instructed to rehydrate or take a break on the premise of continuing exercise / activity ( Step S195).

  As described above, in the preventive measure notification mode (step 50), by executing the flow A while executing the flow B, the WBGT approximate value is measured at a predetermined time interval (5 minutes in the present embodiment). Then, the WBGT level is determined. When the WBGT level changes, the flow B is executed with contents corresponding to the changed WBGT level. When the WBGT level after the change is to stop the user's exercise / activity, it is possible to prevent the user from falling into heat stroke by executing the flow C.

  Next, the processing content of the flow B (program B) executed in step S130 and step S190 will be described with reference to the flowchart shown in FIG. In the flow B, it is possible to execute a hydration flow BD that is a processing flow for instructing the user to supply hydration and a rest flow BR that is a processing flow for instructing the user to take a break. ing.

  In the flow B, first, the notification content data table (table (1) or table (2)) selected in the table selection mode (step S20), the exercise level set in the exercise level setting mode (step S30), and the step Based on the WBGT level measured and determined in S110 or S160, it is determined whether or not to start processing of the hydration flow BD (step S300), and whether or not to start processing of the break flow BR (step S400). ) Is performed.

  Here, for example, the notification content data table (1) is selected in the table selection mode (step S20), the moderate exercise is selected in the exercise level setting mode (step S30), and the WBGT level is selected in step S110 or step S160. A case where is determined to be 2 will be described. In this case, as can be seen from the notification content data table (1), “Drink” is displayed on the liquid crystal display device 8 and the continuous buzzer sound of the piezoelectric buzzer 9 is generated every 20 minutes for 20 seconds. Only a hydration instruction is given to the user. The user is not instructed to take a break. Therefore, in the flow B, in step S300, it is determined whether to start the process of the hydration flow BD (Yes in step S300). In Step B400, it is determined in Step S400 that the rest flow BR is not processed (No in Step S400), and the rest flow BR is maintained in a stopped state (Step S402).

  In the hydration flow BD, following the determination to start the processing of the hydration flow BD (Yes in step S300), the hydration timer for measuring the time of the hydration instruction timing is started. (Step S305). The hydration timer is functionally realized in the CPU 21.

  Next, it is determined whether or not there is a hydration flag DF or a break flag RF set in a hydration flow BD or a break flow BR that has been executed before the WBGT level described later changes (step S310). Here, first, the case where neither the hydration flag DF nor the break flag RF is set before the WBGT level is changed will be described, and the determination of No is made in step S310. Then, it is determined whether or not 20 minutes have passed as a predetermined time interval from the start of timing of the hydration timer (step S305) (step S315), and it is determined whether or not to instruct the user to supply hydration (step S315). Step S320).

  When 20 minutes have elapsed from the start of the hydration timer (step S305) (Yes in step S315) and it is determined that the user is instructed to hydrate (Yes in step S320), the user is hydrated As an instruction, “Drink” is displayed on the liquid crystal display device 8 and the continuous buzzer sound of the piezoelectric buzzer 9 is generated for 20 seconds (step S325).

  On the other hand, for example, when there is a situation such as a break instruction (step S425, step S460) and a hydration instruction (step S325) in the break flow BR, which will be described later, the break instruction is given priority in step S320. Even if No is determined and 20 minutes have elapsed since the start of time measurement of the hydration timer (step S305), the user is not instructed to hydrate.

  After the hydration instruction (step S325) is given to the user, or following the determination that the hydration instruction is not given in step S320 (No in step S320), the determination is made in step S310. The setting of the hydration flag DF and the break flag RF before the change of the WBGT level is canceled (step S330). Here, since it is determined in step S310 that neither the hydration flag DF (pre-change flag) nor the break flag RF (pre-change flag) exists before the WBGT level changes, the flag release processing in step S330 is performed. I will not.

  Subsequently, a flag indicating that the user has been instructed to supply water in step S325 is set as the water supply flag DF (step S335). Even when it is determined in step S320 that the instruction for hydration is not given (No in step S320), the hydration flag DF is set (step S335). Then, the hydration timer is reset (step S340), the process returns to step S305, and until it is determined in step S170 that there is a change in the WBGT level, “Drink” to the liquid crystal display device 8 is performed every 20 minutes. In addition to the display and the sound of the continuous short buzzer sound of the piezoelectric buzzer 9, the operation of updating the previously set water supply flag DF is repeated (steps S310 to S330). The hydration flag DF is also updated when it is determined in step S320 that the hydration instruction is not given (No in step 320).

  As described above, the hydration instruction is given every 20 minutes as a preventive measure against heat stroke, so that heat stroke can be prevented. Note that the 20 minute interval at which the hydration instruction is given is a predetermined time interval at which heat stroke can be effectively prevented, and is not limited to 20 minutes. Can be set.

  When the hydration flag DF is set (step S335), the WBGT level of the environment in which the hydration flow BD is executed is given to the hydration flag DF as an identifier. In other words, the WBGT level determined in step S110 or step S160 is assigned to the hydration flag DF as an identifier. Therefore, in step S310, by determining the identifier relating to the WBGT level given to the hydration flag DF, whether the hydration flag DF is related to the currently executed hydration flow BD or before the WBGT level changes. It is possible to determine whether the hydration flag DF is set in the hydration flow BD or the break flow BR that has been executed.

  Note that the processing when it is determined in step S310 that there is a hydration flag DF or a break flag RF before the WBGT level changes (Yes in step S310) will be described later.

  Next, for example, the notification content data table (1) is selected in the table selection mode (step S20), the moderate exercise is selected in the exercise level setting mode (step S30), and the WBGT level is selected in step S110 or step S160. A case where is determined to be 3 will be described. In this case, as can be seen from the notification content data table (1), “Drink” is displayed on the liquid crystal display device 8 and the continuous buzzer sound of the piezoelectric buzzer 9 is generated every 20 minutes for 20 seconds. A hydration instruction and a break instruction are given to the user.

  The instruction to take a break is to display “REST-20” on the liquid crystal display device 8 and generate a short buzzer sound of the piezoelectric buzzer 9 every 30 minutes for 20 seconds. The hydration instruction is performed by executing the above-described hydration flow BD following the determination of the start of the hydration flow BD processing in step S300 (Yes in step S300). Further, the instruction for the break is made by executing the processes after step S405 described later, following the determination to start the process of the break flow BR in step S400 in flow B (Yes in step S400).

  In the break flow BR, following the determination to start the process of the break flow BR (Yes in step S400), timing of a break timer for measuring the time of the break instruction timing is started (step S405). . The break timer is functionally realized in the CPU 21.

  Next, it is determined whether or not there is a hydration flag DF or a break flag RF set in a hydration flow BD or a break flow BR that was executed before the WBGT level described later changes (step S410). Here, first, a case will be described in which neither the hydration flag DF nor the break flag RF is set before the WBGT level is changed, and the determination of No is made in step S410. Then, it is determined whether or not 30 minutes have elapsed from the start of timing of the break timer (step S405) (step S415), and it is determined whether or not to give a break instruction to the user (step S420).

  When 30 minutes have elapsed from the start of timing of the break timer (step S405) (Yes in step S415) and it is determined to give a break instruction to the user (Yes in step S420), as a break instruction to the user Then, “REST-20” is displayed on the liquid crystal display device 8 and a short buzzer sound of the piezoelectric buzzer 9 is generated for 20 seconds (step S425).

  On the other hand, for example, when the timing for taking a break such as half time is determined during the match time, and there is a situation where this timing and the timing of the break instruction in step S425 overlap, No in step S420. Even if 30 minutes have elapsed since the start of the timing of the break timer (step S405), the user is not instructed to take a break. It should be noted that the timing at which the half-time arrives is previously stored in the RAM 22 or the like in advance in the operation setting mode (any stage from step S10 to step 40).

  After the instruction for the break (step S425) is given to the user or following the determination that the instruction for the break is not given in step S420 (No in step S420), the instruction for the break is given to the user in step S425. A flag indicating that it has been performed is set as a break flag RF (step S430). Even when it is determined in step S420 not to give a break instruction (No in step 420), the break flag RF is set (step S430).

  Then, the break timer is reset (step S435), the process returns to step S405, and “REST-20” to the liquid crystal display device 8 is performed every 30 minutes until it is determined in step S170 that the WBGT level has changed. And the operation of updating the break flag RF set in advance is repeated (steps S410 to S430). The break flag RF is also updated when it is determined in step S420 that a break instruction is not given (No in step 420).

  Thus, as a preventive measure against heat stroke, a break is instructed every 30 minutes, so that heat stroke can be prevented. The 30-minute interval at which a break instruction is given is a predetermined time interval that can effectively prevent heat stroke, and is not limited to 30 minutes. Can be set.

  When the break flag RF is set (step S430), the WBGT level of the environment in which the break flow BR is executed is given to the break flag RF as an identifier. That is, the break flag RF is given the WBGT level determined in step S110 or step S160 as an identifier. Therefore, in step S410, by determining the identifier related to the WBGT level given to the break flag RF, whether the break flag RF is related to the currently executed break flow BR or before the WBGT level is changed is executed. It can be determined whether the rest flag RF is set in the hydration flow BD or the rest flow BR.

  Note that the processing in the case where it is determined in step S410 that the hydration flag DF or the break flag RF before the WBGT level is changed (Yes in step S410) will be described later.

  By the way, as described above, in the flow A, it is determined whether or not the WBGT level has changed at an interval of 5 minutes, and if it is determined that the WBGT level has changed, the flow B or Execution of flow C is selected (step S190). When the flow B is selected, the flow B that has already been executed is terminated, and the process of the flow B based on the changed WBGT level is executed again. Accordingly, the hydration flow BD and the break flow BR of the flow B start the hydration timer and the break timer when starting the processing, so the time interval for giving the hydration instruction and the time interval for giving the break instruction are from the beginning. It will be timed.

  Therefore, for example, when the WBGT level changes from “3” to “2”, the instruction of the preventive measures for heat stroke that was last performed before this change is the hydration that was performed 10 minutes before the change. It may be an instruction. However, in the flow B, a hydration instruction is given at intervals of 20 minutes. For this reason, after the WBGT level has changed from “3” to “2”, the hydration instruction is given 20 minutes after the start of the timing in step S305 of the flow B. There will be no instructions for hydration for minutes, which is not appropriate for preventing heat stroke.

  Therefore, in step S310 and step S410, the presence or absence of the hydration flag DF or the break flag RF set in the flow B that was executed before the WBGT level changed was determined, and it was determined that either flag was present. In such a case (Yes in step S310, Yes in step S410), predetermined processing (step S312 and step S450) is performed.

  Specifically, for example, when the WBGT level changes from “3” to “2”, in the flow B that is executed when the WBGT level before the change is “3”, the hydration flag DF is set in step S335. Is set, and the break flag RF is set in step S430. Accordingly, in step S310 of the hydration flow BD of the flow B executed after the WBGT level is changed from “3” to “2”, there is a hydration flag DF or a break flag RF before the WBGT level is changed. (Yes in step S310).

  In this case (Yes in step S310), after the instruction for the preventive measure against heat stroke performed at the end before the WBGT level is changed, the moisture of the flow B executed after the WBGT level is changed. The time until the time for the replenishment timer is started is added to the time for the water replenishment timer to be timed in step S305 (step S312). As a result, after the WBGT level has changed from “3” to “2”, the first hydration instruction is given as a predetermined time from the hydration or break instruction that was made before the WBGT level changed. It will be done after 20 minutes. That is, it is possible to prevent missed timing of hydration necessary for preventing heat stroke. The predetermined time of 20 minutes is the same as the time set in step S315, and thus heat stroke can be effectively prevented. Note that the predetermined time may be shorter or longer than the time set in step S315 if the heat stroke can be effectively prevented.

  Here, the shorter one of the time since the start of the timing of the hydration timer and the break timer of the flow B, which is stored before the WBGT level is changed, which is stored in the step S180 of the flow A, is expressed as the WBGT level. It is the time from the instruction of the preventive measures for heat stroke performed at the end before the change is made to the start of timing of the hydration timer of the flow B executed after the change of the WBGT level.

  For example, when the WBGT level changes from 2 to 3, in the flow B that was executed when the WBGT level before the change was 2, the hydration flag DF is set in step S335. Therefore, in step S310 of the hydration flow BD of the flow B and step S410 of the rest flow BR executed after the WBGT level is changed from 2 to 3, the hydration flag DF set before the WBGT level is changed is set. It is determined that it is present (Yes in step S310, Yes in step S410).

  In this case, in the hydration flow BD, the same processing as that in the case where the WBGT level is changed from 3 to 2 is executed, and after the WBGT level is changed from 2 to 3, the instruction of the hydration performed first is , 20 minutes after the instruction of hydration or break that is performed before the WBGT level changes.

  On the other hand, in the break flow BR, after the instruction of the preventive measures for heat stroke performed at the end before the WBGT level is changed, the timing of the break timer of the flow B executed after the change of the WBGT level is started. The time until it is added is added to the time measured by the break timer, which is timed in step S405 (step S450). Then, the break timer determines whether or not 30 minutes have been counted including the added time (step S455), and when 30 minutes have been counted (Yes in step S455), a break instruction is given to the user. Then, “REST-20” is displayed on the liquid crystal display device 8 and a short buzzer sound of the piezoelectric buzzer 9 is generated for 20 seconds (step S460). Thus, after the WBGT level has changed from 2 to 3, the first break instruction is given 30 minutes after the hydration instruction given before the WBGT level changes. Become. That is, it is possible to prevent missing a break timing necessary for preventing heat stroke. In addition, hydration is generally performed at the time of a break. Therefore, the hydration is effectively instructed, and heat stroke is effectively prevented from the viewpoint of hydration. By the way, the predetermined time of 30 minutes is the same as the time set in step S415, and thus heat stroke can be effectively prevented. Note that the predetermined time may be shorter or longer than the time set in step S415 as long as heat stroke can be effectively prevented.

  Similarly, in the break flow BR, the time stored in Step S180 of Flow A that is executed before the WBGT level is changed, which is executed before the time of the hydration timer and the break timer of Flow B, is short. This is the time from when the instruction of preventive measures for heat stroke performed at the end before the WBGT level is changed to the start of timing of the break timer of the flow B executed after the change of the WBGT level.

  Then, the setting of the hydration flag DF before the WBGT level is changed is canceled (step S465), the break timer is reset (step S470), and then the break timer is started again (step S405). In step S410, since the setting of the hydration flag DF before the change of the WBGT level in step S465 is cancelled, it is determined that there is no hydration flag DF (No in step S410), and the processing from step S410 to step S440 is performed. Is repeated, and a break instruction is given by the liquid crystal display device 8 and the piezoelectric buzzer 9 every 30 minutes.

  In the above description of the second embodiment, the case where the WBGT level changes from “2” to “3” and the case where the WBGT level changes from “3” to “2” have been described. Alternatively, in the case of changing from “2” to “1” or the like, similarly, based on the hydration flag DF and the break flag RF before the WBGT level is changed, the instruction of the preventive measures for heat stroke after the WBGT level is changed is Performed at the appropriate time.

  In the break flow BR in the thermal index measurement device 1 according to the second embodiment, in step S410, it is determined whether or not the hydration flag DF or the break flag RF is present, so that there is too much time until the break instruction. I am trying not to. However, only the presence or absence of the break flag RF may be determined in step S410. In this case, the addition of time to the break timer performed in step S450 is performed only when a break instruction is given before the WBGT level changes. That is, after the last break instruction before the change of the WBGT level, the time until the start of the break timer of the break flow BR executed after the change of the WBGT level is started in step S405. It will be added to the time measured by the break timer. Even in this case, the instruction of hydration is performed after a predetermined time (20 minutes) from the instruction of hydration performed before the WBGT level is changed in the hydration flow BD. Preventive measures are taken appropriately.

  Further, in the program B in the heat index measuring apparatus 1 according to the second embodiment, when only the process of instructing hydration (hydration replenishment flow BD) is performed, and the process of instructing hydration (hydration replenishment flow) BD) and a process of instructing a break (break flow BR) are combined, and a process of instructing only a break may be performed according to the WBGT level. In this case, in determining whether to start the process of the hydration flow BD in step S300 of the flow B, a determination is made not to perform the process of the hydration flow BD (No in step S300), and the hydration flow The BD process is maintained in a stopped state (step S302). On the other hand, in step S400 of the flow B, a determination to start the processing of the break flow BR (Yes in step S400) is performed, and only the break flow BR is executed, so that only the break instruction is performed.

  In addition, the timing of giving instructions for hydration or break is not limited to the above 20 minutes or 30 minutes, and is enthusiastic considering the user's physical strength, gender, age, user type, exercise and activity level, activity location, etc. A predetermined time interval that can effectively prevent the illness is set.

By doing in this way, notification of heat stroke prevention appropriate widely can be performed. Further, the ROM 20 may be a rewritable ROM, and a notification content data table or the like may be taken in from another device (for example, a personal computer) by wireless / wired communication.

However, other instruction contents, for example, instructions for hydration and rest are given. Or a program for instructing replenishment of minerals, cooling of the head, etc., and an appropriate program may be executed according to the contents of user data and the heat index. .
