The present invention relates to a heat stroke risk evaluation method for evaluating the risk of heat stroke when a plurality of activists are active in a plurality of activity areas, and a heat stroke risk evaluation system.

Conventionally, as a method and system for determining the risk of developing heat stroke, heat stroke is used to determine the risk of heat stroke in a living body based on the measured activity amount of the living body and environmental information such as ambient temperature. A preventive system is known (see, for example, Patent Document 1).

=== This embodiment ===
The heat stroke risk evaluation method of the present embodiment is carried out using the heat stroke risk evaluation system.

<<< Heat Stroke Risk Assessment System >>>
As shown in FIG. 1, the heat stroke risk evaluation system 1 becomes an evaluation target when a plurality of workers M work in a plurality of work areas A (A1, A2, A3) having different environmental conditions. This is performed for each target worker Mt (Mt1, Mt2 ...). Here, the work area A (A1, A2, A3) corresponds to the activity area, the work corresponds to the activity, the worker M (M1, M2 ...) Corresponds to the activator, and the target worker Mt (Mt1, Mt1, Mt2 ...) corresponds to the target activist. In FIG. 1, ● indicates the worker M and the target worker Mt.

In this example, as a plurality of work areas A having different environmental conditions, as shown in FIG. 1, a sunshade area A1 that is outdoors and receives direct sunlight, and a sunshade area A2 that is outdoors and has a sunshade are constructed. The three work areas A of the building area A3 in the building under construction at the construction site are illustrated. However, it is not limited to this. For example, different floors on the ground floor in the building or the ground floor and the basement floor in the building may be used as a plurality of work areas having different environmental conditions, or even on the same floor of the building, they may be flat on each other. Areas with different positions may be used as multiple work areas with different environmental conditions, and in outdoor areas, areas are divided based on differences in ventilation, etc., and each area has different environmental conditions. It may be a plurality of different work areas.

Further, regarding the target worker Mt to be evaluated for the risk of heat stroke, all the worker Ms may be the target worker Mt, or as will be described later, all the worker Ms are predetermined. A part of the worker M satisfying the above conditions may be selected and used as the target worker Mt.

As shown in FIG. 1, the heat stroke risk assessment system 1 includes environmental sensors 3 (31, 32, 33) arranged in each of the work areas A1, A2, and A3, and target workers Mt (Mt1, Mt2 ... ), Activity sensors 4 (41, 42, 43, 44) attached to each), repeaters 5 (51 to 56) appropriately arranged in the work area A (A1, A2, A3), and heat stroke risk. It has a cloud system 10 that executes the evaluation of. Here, the repeater 5 (51-56) corresponds to the activity area device.

Each environment sensor 3 measures the environment state of each work area A1, A2, A3 to which it is arranged, and transmits the environment state data at all times or at an appropriate cycle. In this example, a thermal index is measured as an environmental state, and WBGT data (corresponding to thermal index data) including the thermal index (hereinafter, also referred to as WBGT) is output. Here, the WBGT is also referred to as a "wet-bulb globe temperature", a "heat index", and a "heat stroke index", and the WBGT has a wet-bulb temperature, a black globe temperature, and a dry-bulb temperature. In the case of indoors, it is calculated by the following formula 1, and in the case of outdoors, it is calculated by the following formula 2.

WBGT = 0.7 x wet-bulb temperature + 0.3 x black globe temperature ... Equation 1
WBGT = 0.7 x wet bulb temperature + 0.2 x black globe temperature + 0.1 x dry bulb temperature ... Equation 2
Therefore, each environmental sensor 3 has, for example, a wet-bulb thermometer for measuring the wet-bulb temperature, a black-bulb thermometer for measuring the black-bulb temperature, and a dry-bulb thermometer for measuring the dry-bulb temperature. There is. However, it is not limited to this. That is, if the WBGT can be calculated, a sensor having a configuration other than the above may be used as the environment sensor 3.

Further, in this example, among the above three work areas A1, A2, and A3 in FIG. 1, the environmental sensors 31 and 32 arranged in the outdoor sunbathing area A1 and the sunshade area A2 are outdoors. While the WBGT is calculated by the above formula 2, the environment sensor 33 arranged in the building area A3 in the building is indoors, so the WBGT is calculated by the above formula 1.

Each of the environment sensors 3 arranged in the three work areas A (A1, A2, A3) has a communication unit and a storage unit that can be connected to the cloud system 10 as shown in FIG. In each environment sensor 3, a work area identification ID for identifying work areas A1, A2, and A3 in which each environment sensor 3 is arranged is stored in a storage unit.

Each environment sensor 3 transmits WBGT data to the cloud system 10. At this time, the work area identification ID stored in the storage unit is also transmitted together with the WBGT data. Here, the WBGT data transmitted by the environment sensor 3 and the work area identification ID correspond to the environment information data.

By transmitting the WBGT data and the work area identification ID from the environment sensor 3, the cloud system 10 uses the work area identification ID attached to the received WBGT data to display the received WBGT data in the environmental state of which work area. It is possible to quickly identify whether or not it indicates. It should be noted that the installation of each environmental sensor 3 at the construction site is performed at an appropriate time until the evaluation of the risk of heat stroke is started, for example, before the start of the construction work.

In this example, the case where the work area identification ID is stored in the storage unit of each environment sensor 3 is illustrated, but the case is not limited to this. For example, the environment sensor identification ID for identifying the environment sensor 3 is individually set for each environment sensor 3 without duplication, and the environment sensor identification ID of each environment sensor 3 and the environment are stored in the storage unit of the cloud system 10. When the environment sensor ID table associated with the work area A where the sensor 3 is arranged is stored, each environment sensor 3 transmits its own environment sensor identification ID stored together with the WBGT data, and the cloud system The WBGT data received based on the environment sensor identification ID received in 10 and the environment sensor ID table may be in a form of specifying which work area the environment state is indicated.

Each activity sensor 4 can measure the heart rate (corresponding to the active state) of each target worker Mt worn. Each activity sensor 4 measures the heart rate of each target worker Mt attached to the device, and transmits the heart rate data (corresponding to the activity data) at all times or at appropriate intervals. In this example, a bracelet type activity sensor 4 is used, and the activity sensor 4 is worn on the wrist so as to be in direct contact with the body of each target worker Mt.

As shown in FIG. 2, each activity sensor 4 has a communication unit capable of communicating with the repeater 5, a notification unit such as a speaker, and a storage unit. In the storage unit of each activity sensor 4, a worker identification ID for identifying the target worker Mt who wears each activity sensor 4 is stored.

The heart rate data transmitted from the activity sensor 4 is received by the repeater 5 and transmitted to the cloud system 10 via the repeater 5. The communication unit of the activity sensor 4 continuously transmits a low power consumption beacon signal (Bluetooth Low Energy), and includes the heart rate data and the worker identification ID in the beacon signal for transmission. Here, the heart rate data and the worker identification ID correspond to the activist information data. The beacon signal will be described in detail later.

Since each activity sensor 4 transmits the worker identification ID together with the heart rate data, the cloud system 10 has the worker identification ID attached to the received heart rate data and the worker ID stored in the cloud system 10. Based on the table, it is possible to quickly identify which target worker Mt's activity state the received heart rate data indicates.

Two repeaters 5 (51 to 56) are arranged in the sunbathing area A1, the awning area A2, and the building area A3 at intervals of two.

Each repeater 5 has a first communication unit capable of receiving a beacon signal, a second communication unit capable of connecting to the cloud system 10, and a storage unit. A work area identification ID capable of identifying the work area A in which the repeater 5 is arranged is stored in the storage unit.

Each repeater 5 transmits the received heart rate data and the worker identification ID as well as the work area identification ID stored in the storage unit to the cloud system 10 at all times or at appropriate intervals.

The activity sensor 4 continuously transmits a plurality of types of beacon signals having different reach distances by including heart rate data and worker identification ID information. For example, a beacon signal having a short reach (hereinafter referred to as a short-range beacon signal), a beacon signal having a medium reach (hereinafter referred to as a medium-range beacon signal), and a beacon signal having a long reach (hereinafter referred to as a long distance). Three types of reach distances (referred to as distance beacon signals) emit beacon signals that differ from each other. In FIG. 1, each reachable range (a predetermined range narrower than the work area A) of a plurality of types of beacon signals having different reachable distances is shown by a three-dot chain line.

In each repeater 5 (51-56), at least a long-distance beacon signal transmitted from any position of each work area A1, A2, A3 is arranged in the work area A where each repeater 5 is arranged. It is arranged at a position where it can be received by any of the repeaters 5. That is, the repeater 5 is arranged so that at least one of the repeaters 5 can receive the beacon signal transmitted from any position in each work area A.

Therefore, the beacon signal transmitted from each activity sensor 4 is received by each repeater 5 existing within the reach of the beacon signal. For example, in FIG. 1, the long-distance beacon signal among the beacon signals transmitted from the activity sensor 41 worn by the target worker Mt1 is among the two repeaters 51 and 52 arranged in the Hinata area A1. It is received only by one of the repeaters 52. Therefore, from the received repeater 52, the heart rate data of the target worker Mt1 wearing the activity sensor 41 and the activity information data consisting of the worker identification ID of the target worker Mt1 are added to the Hinata area A1. The work area identification ID of is attached and transmitted. Here, the activist information data and the work area identification ID correspond to the information data in the activity area.

Therefore, the cloud system 10 that has received the signal from the repeater 52 identifies that the target worker Mt1 is working in the Hinata area A1.

Further, in FIG. 1, among the beacon signals transmitted from the activity sensor 43 worn by the target worker Mt3, the long-distance beacon signal is sent to one of the repeaters 52 and the awning area A2 arranged in the Hinata area A1. The arranged repeater 53 and the medium-range beacon signal are received by the other repeater 54 arranged in the awning area A2. Therefore, from each of the received repeaters 52, 53, and 54, the heart rate data of the target worker Mt3 wearing the activity sensor 43 and the worker identification ID of the target worker Mt3 are added to the Hinata area A1. A beacon signal including the activity information data is transmitted with the work area identification ID or the work area identification ID of the awning area A2 attached.

The cloud system 10 that has received the signals from the repeaters 52, 53, 54 transmits a signal including the beacon signal having the shortest reach among the received signals based on the received beacon signal. The device 54 is specified, and the awning area A2 in which the specified repeater 54 is arranged is specified as the work area A in which the target worker Mt3 is working.

As shown in FIG. 2, the environment sensor 3 and the repeater 5 are connected to the cloud system 10, and can be accessed from the outside, for example, the administrator computer 11 of the construction management office 2, or a tablet. Is. In the present embodiment, the cloud system 10 corresponds to a network and a management terminal, but each environment sensor 3 and each repeater 5 are connected not only to the cloud system but also to a communicable network. A management terminal for performing heat stroke risk assessment may be connected to the network.

A program for executing the heat stroke risk evaluation process is stored in the cloud system 10 in advance, and the WBGT reference value and the heart rate reference value, which will be described later, are used for the evaluation process. The table shown is also recorded in advance. Further, the cloud system 10 stores a worker ID table as shown in FIG. 3 in which the name and age of each target worker Mt are associated with the worker identification ID assigned to each target worker Mt. Has been done. Then, the cloud system 10 executes the above program to execute the above evaluation process. This evaluation process will be described later.

The WBGT reference value is a reference value for evaluating the risk of heat stroke for each work area A1, A2, A3 based on the WBGT data transmitted from each environmental sensor 3. That is, the storage unit has a WBGT reference value table in which the WBGT reference value as shown in FIG. 4 is recorded. Then, in the WBGT reference value table, WBGT reference values unique to each of the three work areas A1, A2, and A3 are stored in association with each work area identification ID.

Therefore, the cloud system 10 refers to the WBGT reference value table using the work area identification ID attached to the WBGT data transmitted from each environment sensor 3 as a key, and acquires the WBGT reference value corresponding to the work area identification ID. Then, based on the acquired WBGT reference value and the WBGT data transmitted from each environmental sensor 3, it is possible to determine whether or not there is a risk of heat stroke in each of the work areas A1, A2, and A3.

The WBGT reference values of the work areas A1, A2, and A3 are set at appropriate times before the evaluation system is operated, while considering the work conditions in the work areas A1, A2, and A3. The WBGT standard value will be updated sequentially as the construction work progresses.

In addition, examples of the above-mentioned working conditions to be considered include "working strength", "clothing", "air flow", and "acclimation to heat". Here, the "work intensity" is the magnitude of the metabolic rate level, which is small for light manual work or desk work, but is large for intense hard work. In addition, for "clothing", the type of clothes to be worn when performing work (for example, work clothes, SMS polypropylene coveralls, etc.) is taken into consideration, and for "airflow", the presence or absence of airflow is taken into consideration, and "to heat". For "acclimation", the presence or absence of acclimatization to heat is considered.

The heart rate reference value is a reference value for evaluating the risk of heat stroke for each work area A1, A2, A3 based on the heart rate data transmitted from each activity sensor 4. That is, the storage unit has a heart rate reference value table in which the heart rate reference value as shown in FIG. 5 is recorded. Then, in the heart rate reference value table, the heart rate reference value associated with the age of the worker is stored in association with each work area identification ID.

Therefore, the cloud system 10 refers to the heart rate reference value table using the worker identification ID attached to the heart rate data transmitted from each activity sensor 4 via the repeater 5 as a key, and corresponds to the worker identification ID. The heart rate reference value corresponding to the age of the attached target worker Mt is acquired. Then, based on the acquired heart rate reference value and the heart rate data transmitted from each activity sensor 4, whether or not there is a risk of heat stroke for the target worker Mt working in the work areas A1, A2, and A3 is determined. Can be determined.

<<< Heat stroke risk evaluation method >>>
Next, a heat stroke risk evaluation method using the above heat stroke risk evaluation system will be described.

First, each worker who works at a work site having a plurality of work areas (three work areas in this embodiment) A1, A2, and A3 is at the construction management office 2 before the start of work on the work day. Appear in. Then, the manager determines whether or not the appearing workers M1, M2 ... Are the above-mentioned target workers Mt1, Mt2 ... That is, the target workers Mt1, Mt2 ... For the evaluation target of the risk of heat stroke. To do. For example, when the ages of workers M1, M2 ... Are within a predetermined age range in which heat stroke is likely to occur, and in the case of a job type that wears highly airtight work clothes such as dustproof clothes, the experience of the corresponding work. If the number of years is short, or if the blood pressure value measured at the morning assembly is higher than the predetermined value, it is determined that the target worker Mt1, Mt2 ...

Then, when it is determined that the target workers are Mt1, Mt2 ..., The administrator accesses the cloud system 10 and identifies the target workers Mt1, Mt2 ... and the workers given to the workers on the cloud. Enter in association with the ID. For example, when the target worker Mt1 is ○ △ Ichiro, “M00001” is assigned to the worker identification ID, and the worker name “○ △ Ichiro” and the worker identification ID “M00001” of ○ △ Ichiro are used. Is associated and input. By inputting the data of each target worker Mt1, Mt2 ..., The worker ID table is stored in the cloud system 10. Here, the worker information does not necessarily have to be input before the start of the work on the work day, and may be collectively registered before the work day.

Simultaneously with or after the process of inputting the data of each target worker Mt1, Mt2 ..., the administrator prepares one activity sensor 4 for each target worker Mt1, Mt2 ... It is passed to the target workers Mt1, Mt2 ... Each activity sensor 4 is dedicated to, for example, each target worker Mt1, Mt2 ..., And the worker identification ID of the corresponding target worker Mt1, Mt2 ... Is recorded in the storage unit of the activity sensor 4 in advance. Has been done. For example, in the case of ○ △ Ichiro, since the worker identification ID is “M00001”, the storage unit of the activity sensor 41 prepared for ○ △ Ichiro has “M00001” as the worker identification ID. Is recorded.

The prepared activity sensor 4 is attached to each target worker Mt on the wrist and starts each work at the work site. During the work of the target worker Mt, as shown in FIG. 6, the attached activity sensor 4 attaches the worker identification ID to the heart rate data indicating the measured heart rate of the target worker Mt1, Mt2 ... Person information data is included in three types of beacon signals having different reach and transmitted (activist information data transmission step S1).

The activity information data transmitted from the activity sensor 4 is received by the repeater 5 arranged within the reach of the beacon signal. Therefore, the repeater 5 to be received differs depending on the position where the target worker Mt is working. In addition, the activist information data transmitted from the activity sensor 4 is received by all the repeaters 5 located within the reach of the beacon signal. From each of the received repeaters 5, the activity area information data in which the received activity information data is accompanied by the work area identification ID stored in the storage unit of the repeater 5 is transmitted to the cloud system 10 ( Information data transmission step S2) in the activity area.

On the other hand, each of the environment sensors 3 of the work areas A1, A2, and A3 adds the work area identification ID stored in the storage unit of each environment sensor 3 to the WBGT data of each work area in the cloud system 10. (Environmental information data transmission step S3).

During the work of the target worker Mt, the risk of heat stroke is evaluated for each target worker Mt as follows.

The cloud system 10 receives WBGT data from the environmental sensors 31, 32, 33 of the work areas A1, A2, and A3, respectively, and is attached to each of the target workers Mt1, Mt2 ... From each repeater 5 (51 to 56). The heart rate data transmitted from each activity sensor 4 (41 to 44) is received. At this time, the work area identification ID is attached to each WBGT data, and the worker identification ID and the work area identification ID are attached to the heart rate data.

At this time, as described above, a plurality of heart rate data with the same worker identification ID may be received. Therefore, the cloud system 10 detects data including a beacon signal having a shorter reach from the information indicating the reach of the beacon signal including the heart rate data with the same worker identification ID. That is, the target worker Mt identifies that he / she is working at a position close to the repeater 5 that has received the beacon signal having a shorter reach. Therefore, the cloud system 10 identifies the heart rate and work area of the target worker Mt from the heart rate data and the work area identification ID transmitted from the repeater 5 that has received the beacon signal having a shorter reach.

The cloud system 10 determines the risk of heat stroke for each target worker Mt based on the specified heart rate data and worker identification ID of each target worker Mt and the stored heart rate reference value table. Evaluate (risk evaluation step S4).

Further, at this time, the work area identification ID transmitted from the repeater 5 of the work area A specified that each target worker Mt is working and the same work area identification ID as the work area identification ID are attached. Based on the WBGT data and the WBGT reference value table stored in the cloud system 10, the risk of heat stroke in the work area A where the target worker is working is evaluated (risk evaluation step S4). ..

If the result of the heat stroke risk evaluation based on the heart rate data and the result of the heat stroke risk evaluation based on the WBGT data are both evaluated as "no risk of heat stroke", the work and evaluation are continued. To. On the other hand, when it is evaluated that there is a risk of heat stroke, the cloud system 10 transmits alarm data indicating that fact to, for example, the activity sensor 41 of the target worker Mt1 of the worker identification ID "M00001". To do. Then, the notification unit of the activity sensor 41 of the target worker Mt1 gives a warning to that effect to the target worker Mt1 “○ △ Ichiro”. At this time, if the result of the heat stroke risk evaluation based on the heart rate data and the result of the heat stroke risk evaluation based on the WBGT data are both evaluated as "there is a risk of heat stroke", it indicates that fact. The alarm data may be transmitted to the activity sensor 41 of the target worker Mt1.

According to the heat stroke risk evaluation method of the present embodiment, the working state of the target worker Mt is measured by the activity sensor 4 worn by the target worker Mt, so that a more accurate working state can be grasped. It is possible, and the environmental state of each work area A1, A2, A3 is measured by the environmental sensors 3 arranged in each work area A1, A2, A3, so that a more accurate environmental state can be grasped. Is possible.

Further, the activity data indicating the work state measured by the activity sensor 4 is received by the repeater 5 existing in the work areas A1, A2, and A3 where the target worker Mt is working, together with the worker identification ID. Since it is transmitted together with the work area identification IDs of the work areas A1, A2 and A3 in which the repeater 5 is arranged, it is possible to accurately detect the work areas A1, A2 and A3 in which the target worker Mt is working. Is. Therefore, when the target worker Mt moves to different work areas A1, A2, A3, the target worker Mt is moved from the repeater 5 arranged in the work areas A1, A2, A3 after the movement. The work data and the worker identification ID are transmitted together with the work area identification ID indicating the work areas A1, A2, and A3 after the movement. Therefore, even if the target worker Mt moves to different work areas A1, A2, A3, it is possible to accurately detect the work areas A1, A2, A3 in which the target worker Mt is working.

The risk of heat stroke for each target worker Mt is determined by the work area identification ID transmitted together with the WBGT data indicating the environmental state of the work areas A1, A2, and A3 measured by the environment sensor 3 and the activity sensor 4. The evaluation is performed based on the WBGT data and the heart rate data associated with the measured heart rate data and the work area identification ID transmitted together with the worker identification ID. Therefore, the work areas A1, A2, and A3 in which the target worker Mt is working can be more reliably identified, and the risk of heat stroke for each target worker Mt can be further increased by using more accurate WBTG data and heart rate data. It is possible to evaluate accurately.

Further, since a plurality of repeaters 5 for receiving the data transmitted from the activity sensor 4 are provided for each predetermined area in the work areas A1, A2, and A3, the output of the activity sensor 4 can be kept small. Therefore, the power consumption of the activity sensor 4 can be suppressed to a small value, and the activity sensor 4 can be miniaturized.

Further, since the work areas A1, A2, and A3 of the target worker Mt are detected by the beacon signal, the power consumption of the activity sensor 4 can be suppressed to a small value, and the activity sensor 4 can be easily miniaturized. As described above, by reducing the size of the activity sensor 4, it is unlikely to interfere with the work of the target worker Mt, so that it is possible to ensure good workability of the target worker Mt. It is also possible to specify the position of the target worker Mt in the work areas A1, A2, and A3 in a narrower range.

Further, since the risk evaluation step S4 is executed in the cloud system 10 to which the repeater 51 and the environment sensor 31 are connected, it is evaluated by a mobile terminal or the like, and the state of the target worker Mt is recognized. It is possible. Therefore, the degree of freedom is high, and it is possible to evaluate the risk of heat stroke of the target worker who works in a wider work area at a lower cost.

In the above embodiment, an example in which the environment sensor 3 is connected to the cloud system and transmits WBGT data to the cloud system 10 has been described, but the present invention is not limited to this. For example, as shown in FIG. 7, the environment sensor 3 may be connected to the cloud system 10 via the repeater 5 in the same manner as the activity sensor 41.

In this case, as shown in FIG. 8, the activity sensor 4 transmits the activity information data (activist information data transmission step S11), and the environment sensor 3 transmits the environment data (environmental information data transmission). Step S12), the transmitted environmental data is received by the repeater 5, and is transmitted from the repeater 5 with the received environmental data and the activist information data and the work area identification ID of the repeater 5 (active area). In the information data transmission step S13), the risk of heat stroke for each target worker Mt is evaluated by the cloud system 10 (risk evaluation step S14).

Further, at this time, the work area identification ID transmitted from the repeater 5 of the work area A specified that each target worker Mt is working and the same work area identification ID as the work area identification ID are attached. Based on the WBGT data and the WBGT reference value table stored in the cloud system 10, the risk of heat stroke in the work area A where the target worker is working is evaluated (risk evaluation step S4). .. Here, the environmental data, the activist information data, and the work area identification ID correspond to the information data in the activity area.

By receiving the environmental data transmitted from the environmental sensor 3 by the repeater 5, the output of the environmental sensor 3 can be suppressed to a small value. Therefore, the power consumption of the environmental sensor 3 can be suppressed to a small value, and the environmental sensor 3 can also be miniaturized. At this time, by including the activist information data and the environmental data in the beacon signal and transmitting them from the activity sensor 4 and the environmental sensor 3, the power consumption of the environmental sensor 3 can be suppressed to a small value and the environmental sensor 3 can be made smaller. It is possible to change.

Further, according to the heat stroke risk evaluation system 1 of the present embodiment, the work areas A1, A2, and A3 of the target worker Mt are detected more accurately by the repeater 5 that receives the activist information data from the activity sensor 4. Then, more accurate activity data measured by the activity sensor 4 worn by the target worker Mt, which is transmitted from the repeater 5, and measured by the environment sensors 3 arranged in each work area A1, A2, A3. It is also possible to more accurately evaluate the risk of heat stroke for each target worker Mt based on more accurate environmental data.

Further, the repeater 5 that receives the activity information data from the activity sensor 4 more accurately detects the work areas A1, A2, and A3 of the target worker Mt, and the target worker Mt transmitted from the repeater 5 For each target worker Mt based on the more accurate activity data measured by the attached activity sensor 4 and the more accurate environmental data measured by the environmental sensors 3 arranged in each work area A1, A2, A3. It is also possible to more accurately assess the risk of heat stroke.

In the above embodiment, when the result of the heat stroke risk evaluation based on the heart rate data and the result of the heat stroke risk evaluation based on the WBGT data are evaluated as "there is a risk of heat stroke", the target work An example of transmitting warning information to that effect to the activity sensor 4 of the person Mt has been described, but the present invention is not limited to this. For example, in addition to the activity sensor 4 of the target worker Mt, warning information may be transmitted to the mobile terminal 6 carried by the site manager of the work site where the target worker Mt is working.

Further, at the construction site as shown in FIG. 1, the states of the work areas A1, A2, and A3 change as the construction work progresses. That is, the work areas having different environments from the work areas A1, A2 and A3 may increase, or the work areas A1, A2 and A3 may expand or narrow. In this case, it is possible to more accurately evaluate the risk of heat stroke for each target worker Mt by appropriately arranging an environmental sensor and a repeater corresponding to each changing work area.

In the above embodiment, an example in which the heart rate reference value used for evaluating the risk of heat stroke is stored in the cloud system as a heart rate reference value table has been described, but the present invention is not limited to this. For example, the heart rate reference value may be calculated by a predetermined calculation formula stored in the cloud system based on the input information of the target worker or the like.
