In recent years, there has been a problem that there is a risk of an increase in the number of workers suffering from heatstroke due to working in high-temperature work places.
Patent Literature 1 describes an earplug-type heat stroke alarm device with a built-in device that issues a heat stroke alarm as a countermeasure against heat stroke (see Patent Literature 1).

JP 2010-131209 A

However, there is a problem that it is difficult to perceive the risk of heat stroke, especially in a noisy place, because the sound notification by the earplugs is based on auditory perception.

<Display processing>
Display processing executed by the CPU 251 of the management terminal 20 will now be described with reference to FIG.

Note that the display process is a process of displaying information about the physical strength of the worker on the display screen 21 of the management terminal 20 .
In S110, the CPU 251 determines whether or not the executed display process is the first display process.

The first display process in the present embodiment is applied to an example in which the first display process is started after the work start time of the work day.
When the CPU 251 determines in S110 that the executed display process is the first display process, the process proceeds to S120.

In S120, the CPU 251 executes initial acquisition processing.
Here, the initial acquisition process is a process of acquiring information used for calculating the initial physical strength value Ps and the maximum physical strength value Pmax for each worker wearing the wearable terminal 10 . Details of the initial acquisition process will be described later.

In S130, the CPU 251 executes initial arithmetic processing.
Here, the initial calculation processing is processing for calculating the initial physical strength value Ps and the maximum physical strength value Pmax for each worker wearing the wearable terminal 10 . The details of the initial calculation process will be described later.

On the other hand, when the CPU 251 determines in S110 that the executed display process is not the first display process, the process proceeds to S140.
In S140, the CPU 251 executes acquisition processing. The acquisition process acquires data used to calculate the current physical strength of the worker wearing the wearable terminal 10 from the wearable terminal 10 . Here, the data for calculating the physical strength of the worker is applied to, for example, the worker's body temperature, perspiration amount, heart rate, and data on the ambient temperature and humidity of the worker.

In S150, the CPU 251 executes arithmetic processing. The arithmetic processing is processing for calculating the current physical fitness value P of the worker wearing the wearable terminal 10 acquired by the acquisition processing in S140. The physical strength value P here is a value related to the physical strength of the worker wearing the wearable terminal 10 . The physical strength value P is applied to an example in which the smaller the physical strength value P is, the higher the risk of heat stroke is used. Details of the arithmetic processing will be described later. In addition, when there are a plurality of workers wearing the wearable terminal 10, the physical strength value P is calculated for each worker.

In S160, the CPU 251 executes notification processing, returns to S140, and executes subsequent processing. The notification processing includes display of calculation results. Specifically, as shown in FIG. 6, the calculation result may be displayed as a bar graph representing the physical strength value P for each worker. Each bar graph will be applied to an example showing the ratio of the physical strength value to the maximum physical strength value Pmax. In addition, the color of the notification portion of the bar graph may be classified according to the physical strength value P and displayed.

<Initial calculation processing>
Next, the details of the initial calculation process executed in S130 of the display process will be described with reference to FIG.

In S310, the CPU 251 calculates the maximum physical strength value Pmax. Here, as the maximum physical strength value Pmax, for example, an average physical strength value of a person having a profile similar to that of the worker wearing the wearable terminal 10 may be used. For the maximum physical strength value Pmax, for example, if the worker has average physical strength, a value corresponding to the physical strength of the worker in good physical condition may be set. A value from 500 to 1000 may be set as the value of the maximum physical strength Pmax.

The calculation of the maximum physical strength value Pmax based on the profile information will be described by applying an example of using a known method.
In S320, the CPU 251 calculates the initial physical strength value Ps. Here, the initial physical strength value Ps is the initial value of the physical strength of the day, in other words, the value of the physical strength at the start of work, or the value of the physical strength in a state where the physical strength is not exhausted by the work. For example, the initial physical strength value Ps may be set to a value corresponding to the maximum physical strength value Pmax and the sleep hours of the worker on that day. Specifically, when the sleep time is 6 hours or more, the maximum physical strength value Pmax is set as the initial physical strength value Ps, and when the sleep time is less than 6 hours, the coefficient 0. It may be multiplied by 8 and set as the initial physical strength value Ps. Furthermore, if the sleep time is less than 3 hours, the maximum physical strength Pmax may be multiplied by a coefficient of 0.5 and set as the initial physical strength Ps. Note that the coefficient corresponding to the sleep time may be set as appropriate.

After executing the processing in S320, the CPU 251 terminates the initial arithmetic processing.
<Acquisition processing>
Next, details of the acquisition process executed in S140 of the display process will be described with reference to FIG.

In S410, the CPU 251 acquires environment information. The environmental information referred to here is information about the environment around the wearable terminal 10 , and for example, an example including the temperature and humidity around the wearable terminal 10 will be described. The temperature and humidity information will be described by applying an example of measurement by the temperature/humidity sensor 117 provided in the wearable terminal 10 . The temperature and humidity information acquired here will be described by applying an example in which the temperature and humidity are average values within a predetermined unit time.

In S420, the CPU 251 acquires body temperature information. The body temperature information here is information on the body temperature of the worker wearing the wearable terminal 10 . Body temperature information may be measured by a body temperature sensor 111 arranged on the wearable terminal 10 . The body temperature represented by the body temperature information acquired here is applied to an example in which the body temperature is an average value within a predetermined unit time.

In S430, the CPU 251 acquires perspiration amount information. The perspiration amount information here is information relating to the perspiration amount of the worker wearing the wearable terminal 10 . The perspiration amount information is applied to an example in which information measured by the perspiration amount sensor 113 arranged in the wearable terminal 10 is used. The sweating amount represented by the sweating amount information acquired here will be described by applying an example in which the sweating amount is the total amount of sweating within a predetermined unit time.

In S440, the CPU 251 acquires heart rate information and terminates the acquisition process. The heart rate information here is information on the heart rate of the worker wearing the wearable terminal 10 . The heart rate information will be described by applying an example in which the information measured by the heart rate sensor 115 arranged on the wearable terminal 10 is used.

<Calculation processing>
Next, details of the arithmetic processing executed in S150 of the display processing will be described with reference to FIG.

In S510, the CPU 251 sets the physical strength value P. For the physical strength P set here, the initial physical strength Ps calculated in S320 is set for the first time. Also, from the second time onwards, the physical strength value P calculated in S520 of the most recent calculation process is set.

In S520, the CPU 251 calculates the physical strength value P. Here, the physical strength value P is calculated by subtracting based on the work time. The details of the calculation of the physical strength value P will be described later.
In S530, the CPU 251 determines whether or not a warning condition is satisfied. The warning condition here is a condition for determining whether or not it is a situation in which work should be interrupted and a break should be made.

Specifically, for example, it may be determined that the warning condition is satisfied when the physical fitness value P calculated in S520 is less than a predetermined threshold value.
When the CPU 251 determines in S530 that the warning condition is satisfied, the process proceeds to S540.

In S540, the CPU 251 sets the warning to ON.
On the other hand, when the CPU 251 determines in S530 that the warning condition is not satisfied, it ends the arithmetic processing. In other words, the arithmetic processing ends while the warning is turned off.

<Physical strength value calculation>
Calculation of the physical fitness value P will be described by applying it to an example of calculation as follows, for example.
Physical fitness value P=past physical fitness value Pp-10*unit work time T*work coefficient Here, the work coefficient is set based on body temperature, perspiration amount, heart rate, and temperature/humidity data. The work coefficient may be calculated by setting 1 as an initial value and multiplying it according to the data of body temperature, perspiration amount, heart rate, and temperature/humidity.

For example, if the body temperature is 36.9° C. or less, the work coefficient is multiplied by 1, and if the body temperature is 37.0° C. or more and 37.9° C. or less, the work coefficient is multiplied by 1.5. Multiply the work factor by 2.0 above 38.0°C.

If the perspiration is less than 1 liter per hour, the work factor is multiplied by 1; if it is 1 liter or more and less than 2 liters per hour, the work factor is multiplied by 1.5. Also, if it is 2 liters or more per hour, the work factor is multiplied by 2.0.

If the heart rate is less than 60 beats per minute, multiply the work factor by 1; if it is greater than or equal to 60 beats per minute and less than 90 beats per minute, multiply the work factor by 1.5. Also, if the number is 90 or more per minute, the work coefficient is multiplied by 2.0.

If the air temperature is less than 25°C, the work factor is multiplied by 1.0; Also, if the air temperature is 30° C. or higher, the work coefficient is multiplied by 2.0.

The unit work time T may be set, for example, to a time corresponding to the period in which the physical fitness value P is updated, and may be set to 1, for example, 10 minutes. That is, for example, when the work count is 1, the physical strength value P may be calculated to decrease by 10 every 10 minutes.

<Notification processing>
Next, details of the arithmetic processing executed in S150 of the display processing will be described with reference to FIG.

In S610, the CPU 251 determines whether or not warning is set to ON. Here, the warning is ON means that the warning setting is ON in S540 of the arithmetic processing.

When the CPU 251 determines in S610 that the warning is not ON, in other words, the warning is set OFF, the process proceeds to S620.
In S620, the CPU 251 sets the display mode for displaying the physical strength value P in S630, which will be described later. Here, the display mode of the physical strength value P will be described by applying an example that is set according to the ratio of the physical strength value P to the maximum physical strength value Pmax. Specifically, the physical strength value P may be set to be color-coded such that red is less than 30%, yellow is 30% or more and less than 50%, and green is 50% or more.

At S630, the CPU 251 displays the physical strength value P on the display screen 21 of the management terminal 20 according to the display mode set at S620. Here, when there are a plurality of wearable terminals 10 , data for each wearable terminal 10 , that is, for each worker wearing the wearable terminal 10 is displayed on the display screen 21 . After S630, the CPU 251 ends the notification process.

Returning to S610, when the CPU 251 determines in S610 that the warning is set to ON, the process proceeds to S640.
In S<b>640 , the CPU 251 displays a warning on the display screen 21 of the management terminal 20 . The warning display here is a display indicating that there is a high possibility that the worker will suffer from heat stroke. Note that in S640, together with the highlight display, the data of the worker who triggered the turning-on of the warning may be highlighted so that it is easy to see. Specifically, if there is data on multiple workers, and there is data on a worker with a high possibility of suffering from heat stroke, it is possible to identify the worker with a high possibility of suffering from heat stroke. may be highlighted in the display.

In S650, the CPU 251 communicates with the wearable terminal 10 to issue a warning. The warning notification is notification for notifying the worker wearing the wearable terminal 10 that there is a risk of heat stroke.

After the processing in S650, the CPU 251 shifts the processing to S620 and executes subsequent processing.
[3. effect]
The notification system 1 of this embodiment includes an acquisition unit, a calculation unit, and a notification unit. The acquisition unit acquires at least one of dehydration state information and body temperature information for each worker. The computing unit computes the physical fitness value of the worker based on at least one of the dehydration state information and the body temperature information of each worker acquired by the acquiring unit. The notification unit performs notification by displaying the physical strength value of the worker calculated by the calculation unit.

According to such a configuration, the risk of heat stroke can be determined from the displayed physical fitness value of the worker.
An aspect of the present disclosure may include an alarm notification unit that issues an alarm when a predetermined alarm condition is satisfied. The warning condition may include that the worker's physical fitness value calculated by the calculation unit is less than a predetermined threshold.

According to such a configuration, the warning is issued when the warning condition is satisfied, so that it can be determined that the physical strength value of the worker is equal to or less than the threshold value upon receiving the warning. Risk can be determined.

In one aspect of the present disclosure, the calculation unit may calculate the physical strength value by subtracting the initial physical strength value, which is the initial physical strength value of the worker, as the working time elapses.
According to such a configuration, since notification based on the calculated physical fitness value is given as the working time elapses, it is possible to confirm the change in the worker's risk of heat stroke as the working time elapses.

In one aspect of the present disclosure, the calculation unit may calculate the physical strength value by subtracting the physical strength value each time a predetermined unit time elapses.
According to such a configuration, since the physical strength value is calculated by subtracting the physical strength value every predetermined unit time, it is possible to check the change in the physical strength value each time the unit time passes.

In one aspect of the present disclosure, the calculation unit, in the subtraction of the physical strength value per unit time, increases the amount of subtraction of the physical strength value per unit time as the amount of perspiration in the unit time increases. may be configured.

According to such a configuration, the amount of subtraction from the physical strength value increases as the amount of perspiration per unit time increases. Therefore, it can be confirmed that the risk of heat stroke is high when the amount of perspiration is large.

According to such a configuration, the amount of subtraction from the physical strength value increases as the body temperature per unit time increases. Therefore, it can be confirmed that the risk of heat stroke is high when the body temperature is high.

[4. Other embodiments]
(1) In the above embodiment, it is determined that the warning condition is satisfied when the physical strength value P is equal to or less than a predetermined threshold value. However, the warning conditions are not limited to those based on the physical fitness value P. For example, it may be determined that the warning condition is satisfied when the temperature represented by the acquired environmental information is equal to or higher than the temperature at which work can be continued. Further, when the values obtained from the body temperature sensor 111, the perspiration sensor 113, the heartbeat sensor 115, etc. are determined to be the premonitory symptoms of heat stroke, it may be determined that the warning conditions are met. For example, it may be determined that the warning condition is satisfied when the worker's body temperature acquired by the body temperature sensor 111 is equal to or higher than a predetermined threshold such as 37° C. or higher.

(2) Moreover, among the sensors 11 arranged in the wearable terminal 10, a plurality of sensors may be used to determine whether or not the warning conditions are satisfied. For example, it may be determined that the warning condition is satisfied when the amount of perspiration measured by the perspiration amount sensor 113 has decreased and the temperature indicated by the temperature/humidity sensor 117 has not decreased. That is, since a symptom of a decrease in the amount of perspiration can occur as a sign of heat stroke, a warning condition corresponding to such a symptom may be set.

(3) Further, as shown in FIG. 12, the notification system 1 of the above embodiment may be further provided with a server 30 capable of communicating with the management terminal 20 . The server 30 may store, for example, information necessary for determining whether or not there is a high possibility of suffering from heat stroke. Specifically, the server 30 may store information such as past cases of heat stroke. For example, in past cases of heat stroke, body temperature information and perspiration amount information, which are precursors of heat stroke, may be stored. Also, environmental information that is considered to be highly likely to cause heatstroke may be stored.

(4) The server 30 may also be configured to share information related to heat stroke with other servers 30 owned by the notification system 1 . Specifically, it may be configured to transmit and receive information through a network such as the Internet.

(5) The server 30 may have a configuration that learns the data values in the case of heat stroke from the sensor data when the worker had heat stroke in the past.
(6) Furthermore, the server 30 may execute at least part of the processing executed by the wearable terminal 10 or the management terminal 20 in the above embodiments. Specifically, the processing load on the management terminal 20 may be reduced by executing the arithmetic processing on the server 30 . In such a case, data necessary for arithmetic processing may be transmitted from the wearable terminal 10 or the management terminal 20 to the server 30 .

(7) In the above-described embodiment, an example in which the physical strength value P is subtracted by performing work has been described. The physical strength value P may be added by resting. The addition of the physical strength value P due to the break may be added according to the length of the break time and the surrounding environment of the worker during the break. That is, the physical strength value P may be increased as the break time is longer, or the physical strength value P may be increased as the ambient temperature of the worker during the break is more appropriate. The start of the rest period may be set by operating the management terminal 20 . The amount of addition of the physical fitness value P during the rest period may be set according to information acquired by the sensors 11 of the wearable terminal 10 . Alternatively, the physical strength value P may be increased by a certain amount by operating the terminal of the management terminal 20 .

(8) In the above embodiment, the physical strength value P is displayed like a bar graph, but the physical strength value P is not limited to being displayed like a bar graph. 13 may be represented by a circular graph. This circular graph may be displayed so that the area of the circular graph increases according to the magnitude of the physical fitness value P, as shown in FIG. 14 . Further, similarly to the case where the physical strength value P is represented by a bar graph, the display mode of the graph representing the physical strength value P may be changed according to the ratio of the physical strength value P to the maximum physical strength value Pmax.

(9) In the above embodiment, an example was described in which the wearable terminal 10 and the management terminal 20 communicate via the Internet. However, the wearable terminal 10 and the management terminal 20 are not limited to direct communication. For example, communication may be performed via a communication terminal such as a smart phone owned by the worker.

(10) In acquiring profile information in the initial acquisition process of the above embodiment, the water content in the body may be acquired.
The water content in the body may be calculated from muscle mass. The muscle mass obtained from a body composition meter or the like may be used.

Moreover, it may be configured such that it is difficult to determine that a person with a high moisture content in the body is suffering from heat stroke.
Specifically, for example, in the initial calculation process, the basic physical strength value or the maximum physical strength value may be set high. Further, in the calculation of the physical strength value in the arithmetic processing, the reduction width of the physical strength value may be reduced.

(11) Body fat percentage may be acquired in the acquisition of profile information in the initial acquisition process of the above embodiment.
The body fat percentage obtained by communication from a body composition meter or the like may be used.

For a person with a high body fat percentage, there is a lot of subcutaneous fat and the skin temperature does not rise easily, so it is difficult to dissipate heat.
Specifically, for example, in the initial calculation process, the basic physical strength value or maximum physical strength value may be set low. Further, in the calculation of the physical strength value in the arithmetic processing, the physical strength value may be configured to decrease by a large amount.

(12) In the acquisition process of the above embodiment, information on the amount of perspiration is acquired, and the physical strength value is decreased as the amount of perspiration increases. However, the physical strength value may be decreased according to not only the amount of perspiration but also the amount of urination.

(13) Further, the amount of perspiration and the amount of urination may be measured using information on body weight or body water content and water content.
(14) In the above embodiment, the amount of perspiration and the amount of urination are not limited to being calculated directly, and may be calculated according to the perspiration ability or urination ability of the worker.

(15) In the arithmetic processing of the above embodiment, the warning is turned on when the warning condition is satisfied, but the warning condition may include the case where the blood pressure is lower than a predetermined value. When the risk of heat stroke is high, skin blood vessels dilate and blood pressure drops due to an increase in body temperature. Therefore, with such a configuration, it is possible to issue a warning when the risk of heat stroke is high.

(16) In the initial acquisition process and the acquisition process of the above embodiments, the worker information and the like may be acquired from other devices.
