<Outline of network system operation>

Heat stroke is said to be caused by an increase in the core temperature of the body (also called core body temperature). It is known that heat stroke damages the heart and brain, and when it becomes severe, it leads to death and sequelae. Core temperature and body surface temperature often do not correlate, making it difficult to predict heat stroke before the onset. However, the part where the core temperature correlates is equipped with a blood vessel for heat dissipation called AVA blood vessel (arteriovenous anastomosis), which is concentrated on the palm, sole, and face, and when these perform heat dissipation, other parts. It rises significantly from the surface temperature of. By observing this heat dissipation mechanism of the human body, it is possible to detect an increase in core body temperature.

Therefore, in the present embodiment, as shown in FIGS. 1 to 3, the measuring device 200 is attached to the body of the measurement target and correlates with the surface temperature of the measurement target and the core temperature of the measurement target. The temperature of the easy-to-use part, the ambient temperature, and the ambient humidity are measured and uploaded to the server 100. As a result, the server 100 detects that there is a high risk of heat stroke with higher accuracy than before, based on the surface temperature, the core temperature, the air temperature, and the humidity from the measuring device 200.

Hereinafter, the configuration of each device of the network system 1 for realizing such a function will be described in detail.

The CPU 210 stores the data in the memory 220.

In the present embodiment, the air temperature sensor 253 is fixed so as to be located at a position away from the surface of the body of the person to be measured in the frame 201.

The CPU 210 stores the data in the memory 220.

In the present embodiment, the humidity sensor 254 is fixed so as to be located at a position away from the surface of the body of the person to be measured in the frame 201. The humidity sensor 254 measures the humidity around the measuring device 200 according to the instruction of the CPU 210, and returns the data to the CPU 210. The CPU 210 stores the data in the memory 220.

The communication antenna 260 exchanges data with other devices such as the server 100 via a WiFi router, a carrier network, the Internet, and the like. For example, the CPU 210 periodically obtains data such as the surface temperature of the measurement target person, the temperature correlated with the core temperature of the measurement target person, the air temperature, the humidity, and the measurement date and time for a predetermined period of time. Upload to the server 100 via.

<Configuration of server 100>

Next, one aspect of the configuration of the server 100 will be described with reference to FIG. The server 100 according to the present embodiment includes a CPU 110, a memory 120, an operation unit 140, and a communication interface 160 as main components.

The CPU 110 controls each part of the server 100 by executing a program stored in the memory 120. For example, the CPU 110 executes a program stored in the memory 120 and executes various processes described later by referring to various data.

The memory 120 is realized by various RAMs, various ROMs, and the like, may be included in the server 100, may be detachable from various interfaces of the server 100, or may be detachable from the server 100. It may be a recording medium of another device accessible from. The memory 120 is core such as a program executed by the CPU 110, data generated by the execution of the program by the CPU 110, device information data 121 relating to a plurality of measuring devices 200, history information data 122 received from the plurality of measuring devices 200, and the like. Stores the data required for the temperature abnormality detection service.

With reference to FIG. 6, the device information data 121 includes the measuring device identification information, the user identification information, the user's age, the user's gender, and the user's height for each measuring device or user registered in the service. It stores the correspondence between the user's weight, the user's BMI (Body Mass Index), the user's disease, and the like.

With reference to FIG. 7, the history information data 122 includes surface temperature history information, core temperature history information, temperature history information, and humidity history for each measuring device or user registered in this service.

The CPU 110 receives measurement data of various sensors 251,252, 253, 254 and measurement date / time data from the measuring device 200 via the communication interface 160. On the contrary, the CPU 110 transmits voice data, text data, or the like of an alarm notifying the danger of heat stroke to the measuring device 200 via the communication interface 160.

By being configured in this way, the CPU 110 of the server 100 is enthusiastic about the measurement target person based on the transition of the surface temperature and the transition of the core temperature for each of the plurality of measuring devices 200, as shown in FIG. It determines whether or not the situation is prone to illness, and outputs a warning based on the determination result.
<Information processing of server 100>

Next, the information processing of the server 100 in the present embodiment will be described with reference to FIG. 9. The CPU 110 of the server 100 periodically or each time it receives data from the measuring device 200, executes the following processing according to the program of the memory 120.

First, the CPU 110 is transmitted from the measuring device 200 via the communication interface 160 to the surface temperature of the measurement target person, the temperature correlated with the core temperature of the measurement target person, the ambient temperature of the measuring device 200, and the ambient humidity of the measuring device 200. Is received (step S102).

The CPU 110 accumulates the surface temperature, the core temperature, the air temperature, and the humidity received from the measuring device 200 in the history information data 122 as one block in association with the measuring device 200 and the measurement date and time (step S104). ..

The CPU 110 calculates a score indicating the possibility of heat stroke regarding the block this time based on the surface temperature, the core temperature, the air temperature, and the humidity (step S106).

For example, the CPU 110 determines that the higher the surface temperature, the higher the possibility of heat stroke, and the lower the surface temperature, the lower the possibility of heat stroke. Further, the CPU 110 determines that the higher the core temperature, the higher the possibility of heat stroke, and the lower the core temperature, the lower the possibility of heat stroke. Further, the CPU 110 determines that the higher the temperature, the higher the possibility of heat stroke, and the lower the temperature, the lower the possibility of heat stroke. Further, the CPU 110 determines that the higher the humidity, the higher the possibility of heat stroke, and the lower the humidity, the lower the possibility of heat stroke.

Further, the CPU 110 determines that the longer the surface temperature is high, the higher the possibility of heat stroke, and the longer the core temperature is high, the higher the possibility of heat stroke is determined, and the time when the temperature is high is high. It is judged that the longer the time, the higher the possibility of heat stroke, and the longer the humidity is, the higher the possibility of heat stroke.

For example, specifically, first, in step S106, the CPU 110 receives the surface temperature of the measurement target, the core temperature of the measurement target, and the ambient temperature of the measurement device 200, which are received this time, based on the data in the table below. The number of block points corresponding to the ambient humidity of the measuring device 200 is calculated.

Then, based on the table below, the CPU 110 determines whether the situation is urgent, requires attention, or is normal, based on the total number of block points for the past several times. Determine (step S110).

When it is determined that the situation is highly urgent or the situation requires attention (YES in step S110), the CPU 110 urges the measuring device 200 via the communication interface 160. Information indicating that the situation is high or information indicating that the situation requires attention is transmitted (step S112).

As a result, when the CPU 210 of the measuring device 200 receives the information from the server 100 via the communication antenna 260, the information indicating that the situation is highly urgent or a situation requiring attention is required from the speaker 270. Information indicating that the above is output by voice. The measuring device 200 may have a display or a light, output the above information from the display, or turn on the light corresponding to the above information.

The CPU 110 waits for measurement data from the next measuring device 200.

As described above, in the present embodiment, the heat is based not only on the high surface temperature, the high core temperature, the high temperature, and the high humidity, but also on whether they continue to be high. Since the risk of the disease is judged, the possibility of heat stroke can be judged with higher accuracy than before. More specifically, in ordinary devices, "stress-induced hyperthermia" is often misjudged as fever or heat stroke. This is because "stress-induced hyperthermia" is caused by mental stress, such as being surprised or making mistakes, and behaves in the same way as a core temperature rise in the short term of a few seconds to a few minutes. be. In the network system 1 according to the present embodiment, since the score accumulation and the correction value by time are introduced, the influence of the high temperature due to the stress for a short time can be suppressed.
<Second embodiment>

In addition to the above-described embodiment, in the present embodiment, the parameters for determining the possibility of heat stroke are changed according to the physique and attributes of the person to be measured. For example, based on the height, weight, BMI, etc. of the measurement target, the measurement target who is prone to heat stroke is corrected so that the block score is calculated higher.

Specifically, in the present embodiment, in step S106, the CPU 110 receives the surface temperature of the measurement target person and the temperature correlated with the core temperature of the measurement target person, based on the data in the table below. The number of block points corresponding to the ambient temperature of the measuring device 200 and the ambient humidity of the measuring device 200 is corrected.

Alternatively, instead of making corrections based on BMI, or in accordance with BMI corrections, the parameters for determining the possibility of heat stroke may be changed depending on the time zone. By combining the body temperature rise rhythm (circadian rhythm) of the person to be measured and the time placed in a hot environment, it is possible to capture the rise in the core temperature with higher accuracy, which can be useful for detecting heat stroke and infectious diseases. .. Regarding the circadian rhythm of the subject to be measured, the body temperature is highest around 16:00 of the day, and the time of transportation due to heat stroke also peaks at 16:00. It is thought that this is a combination of changes in body temperature due to circadian rhythm, fatigue in a hot environment, and dehydration.

Therefore, in step S106, in order to take into account the increase in body temperature due to circadian rhythm, the CPU 110 adds 1 point when the block score is 9 or more from 13:00 to 15:00, and the block score is 9 or more from 15:00 to 18:00. In that case, add 1.5 points.

Alternatively, in step S106, when the surface temperature exceeds 37 ° C. for 5 blocks or more continuously, the CPU 110 is likely to be in a heat generation or fatigue state, so 5 points are added per block.

In addition, the CPU 110 has 3 blocks (9) in which the difference between the surface temperature and the surface temperature of the AVA blood vessel (arteriovenous anastomosis) is within 0.3 ° C or the temperature of the portion correlating with the deep body temperature is 37 ° C or higher. If the score is 5 or more in succession for minutes) or more, it may be determined that heat dissipation due to dilation of the AVA blood vessel (arteriovenous anastomosis) has started, and the measuring device 200 may be first alerted via the communication interface 160. Note that the alert means lighting, vibration, or mail transmission from the server 100 by the LED of the measuring device 200.

Further, when such a state is continuous for 6 blocks or more, the CPU 110 transmits information indicating that the situation is highly urgent to the measuring device 200, and outputs the information.

Further, the CPU 110 may determine that it is in a heat exhaustion state and call attention when more than half of the past 60 minutes (20 blocks) represent a heat exhaustion state even if it is not continuous.

Further, since the CPU 110 is suspected of generating heat when the temperature and humidity are low and both the surface temperature and the core temperature are equal to or higher than a predetermined value, the CPU 110 measures the heat generation alert when the state continues for 20 blocks or more. To output the information.
<Third embodiment>

In the above embodiment, as shown in Table 1, based on the block score for each measurement timing, as shown in Table 2, by calculating the total score in a predetermined length period, the total score is calculated. It was to determine the possibility of heat stroke. However, it is not limited to such a form.

For example, as shown in FIG. 8, the server 100 may determine that the possibility of heat stroke is high when the time when the core temperature exceeds the predetermined value exceeds the predetermined period. Alternatively, the server 100 may determine that when the temperature is equal to or higher than a predetermined value and the time when the core temperature exceeds the predetermined value exceeds the predetermined period, the possibility of heat stroke is high.

Alternatively, as shown in FIG. 8, the server 100 may determine that the possibility of heat stroke is high when the time when the core temperature exceeds the surface temperature exceeds a predetermined period. Alternatively, the server 100 may determine that when the air temperature is equal to or higher than a predetermined value and the time when the core temperature exceeds the surface temperature exceeds a predetermined period, the possibility of heat stroke is high.

More specifically, the information processing of the server 100 in the present embodiment will be described with reference to FIG. 10. The CPU 110 of the server 100 periodically or each time it receives data from the measuring device 200, executes the following processing according to the program of the memory 120.

First, the CPU 110 receives the surface temperature of the measurement target person, the core temperature of the measurement target person, the temperature around the measurement device 200, and the humidity around the measurement device 200 from the measurement device 200 via the communication interface 160 ( Step S102).

The CPU 110 associates the surface temperature, the core temperature, the air temperature, and the humidity received from the measuring device 200 with the measuring device 200 and stores them in the history information data 122 (step S104).

Specifically, the CPU 110 determines whether or not the core temperature exceeds the surface temperature (step S206).

When the core temperature exceeds the surface temperature (YES in step S206), the CPU 110 increments the temperature reversal count of the memory 120 by +1 (step S208).

The CPU 110 determines whether or not the temperature reversal count exceeds a predetermined value, for example, "5" (step S210).

When the reversal count exceeds a predetermined value (YES in step S210), the CPU 110 informs the measuring device 200 via the communication interface 160 of information indicating that the risk of heat stroke is high. Transmit (step S212).

As a result, when the CPU 210 of the measuring device 200 receives the information from the server 100 via the communication antenna 260, the speaker 270 outputs information indicating that the risk of heat stroke is high by voice.

If the core temperature does not exceed the surface temperature (NO in step S206), the CPU 110 resets the temperature reversal count of the memory 120 to 0 (step S214).

As described above, also in the present embodiment, since the risk of heat stroke is determined based not only on the high surface temperature and the high core temperature but also on whether they continue to be high, the risk of heat stroke is determined as compared with the conventional case. It is possible to judge the possibility of heat stroke with high accuracy.
<Fourth Embodiment>

In the above embodiment, the server 100 transmits an alarm to the effect that there is a high possibility of heat stroke to the measuring device 200. In the present embodiment, as shown in FIG. 11, the server 100 sends the information to the communication terminal 300 used by the administrator of the measurement target or the like in place of the measuring device 200 or in addition to the measuring device 200. Is to send.

That is, in FIG. 9, when it is determined that the situation is highly urgent or the situation requires attention (YES in step S110), the CPU 110 passes through the communication interface 160. Information indicating that the situation is highly urgent or information indicating that the situation requires attention is transmitted to the measuring device 200 or the communication terminal 300 associated with the measurement target person (step S112). ).

As a result, when the CPU of the communication terminal 300 receives the information from the server 100, the information indicating that the situation is highly urgent or the information indicating that the situation needs to be alerted from the display or the speaker. Is displayed or output as audio.
<Fifth Embodiment>

In the above embodiment, the surface temperature is measured near the shoulder of the measurement target person, and the temperature correlated with the core temperature is measured near the neck of the measurement target person. However, it is not limited to such a form.

For example, the measuring device 200 may measure the temperature of the mouth, rectum, eardrum, peripheral limbs, pinna, earlobe, and nose as the temperature that correlates with the core temperature.

Further, for example, the measuring device 200 may measure the temperature of the armpits, arms, legs, etc. as the surface temperature.
