Description

Information processing apparatus, information processing method and program

[0001] The present invention relates to an information processing apparatus, an information processing method and a program.

[0002] Conventionally, there is a technology for issuing a heat stroke onset alarm when vital information of a worker exceeds a threshold (see, for example, Patent Document 1).

[0003] Japanese Unexamined Patent Application Publication No. 2023-44283

[0004] However, in recent years, importance has been placed on preventing heat stroke from occurring rather than responding after onset. Currently, for heat stroke prevention, a manager manually manages a wide variety of management items that differ for each worker, but improvements have been called for against the problem that operation is complicated, burdensome, and timely response is difficult. However, conventional technologies including the technology of Patent Document 1 cannot sufficiently meet such demands.

[0005] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a technology capable of reducing the burden on a manager and enabling timely response for heat stroke prevention.

[0006] In order to achieve the above object, an information processing apparatus according to one aspect of the present invention comprises: first reference value acquisition means for acquiring a first reference value at a site where workers are present, with a standard relating to work environment defined by a predetermined official standard-setting organization as a first reference; worker site information acquisition means for acquiring, as worker site information, information relating to a combination of one or more states among a plurality of types of physical states of the worker present at the site and a plurality of types of work states; second reference value calculation means for calculating a second reference value for the worker present at the site based on the worker site information, with a standard indicating the degree of tolerance to a person's work environment as a second reference; and third reference value calculation means for calculating a third reference value of the worker present at the site based on a difference value between the first reference value and the second reference value, with a standard indicating the degree of risk of heat stroke in a person as a third reference.

[0007] Each of the information processing method and program according to one aspect of the present invention corresponds to each of the information processing apparatus according to one aspect of the present invention.

[0008] According to the present invention, it becomes possible to reduce the burden on administrators regarding heatstroke prevention and to take timely action.

[0010] Embodiments of the present invention will be described below with reference to the drawings.

[0011] First, with reference to Figure 1, an overview of the service (hereinafter referred to as "the Service") that can be realized by an information processing system to which a server according to one embodiment of the information processing device of the present invention is applied (see Figure 2, which will be described later) will be explained. Figure 1 is a diagram showing an overview of the Service that can be realized by an information processing system to which a server according to one embodiment of the information processing device of the present invention is applied.

[0012] This service reduces the burden on administrators regarding heatstroke prevention and enables timely responses.

[0013] Specifically, Figure 1 shows the processing flow from step S1 to step S4 as an example of the service. This service is implemented at multiple work sites (work site A and work site B in Figure 1), centered around server 1. Server 1 is an information processing device that provides the heatstroke prevention support service, which is this service. At each work site, work site A and work site B, there is a foreman (manager F; only work site A is shown in the figure) and several workers SW. The foreman has a smartphone-shaped terminal as the manager terminal 2 (foreman terminal), and the workers SW wear smartwatch-shaped terminals as worker mobile terminals 3. A WBGT measuring device 4 is installed at each work site to measure the WBGT value of the work site. Gateway 5 is a device that converts Bluetooth® communication from the WBGT measuring device 4 and worker mobile terminals 3 into mobile communication. Cameras 6 are installed at each work site and capture images of the conditions at each work site. For example, the administrator terminal 2 (head office terminal) at the head office HO is shown in the form of a notebook PC and is used by the head office administrator F. In Figure 1, arrows are shown between server 1 and each of the above devices, and these arrows represent the flow of information. At the bottom of Figure 1, steps S1 to S4 are shown side by side as the processing flow of this service.

[0014] In step S1, Server 1 acquires attendance information and administers a short quiz. Specifically, the foreman uses Administrator Terminal 2 to interview each worker SW and inputs the interview information. The interview information includes physical condition, rest and hydration status, medical history, work intensity, clothing, heat acclimatization status, etc. Server 1 also administers a short quiz to the foreman regarding heatstroke prevention. The quiz is weighted by AI analysis, and high-risk questions are given priority. Server 1 manages the results of the quiz.

[0015] In step S2, server 1 collects information during the work. Specifically, server 1 obtains the WBGT value of the work site from the WBGT measuring device 4. Server 1 also obtains vital information such as heart rate, blood oxygen saturation, and activity level from the worker's mobile terminal 3. Furthermore, server 1 obtains images of the work site from camera 6. This information is collected in real time and transmitted to server 1.

[0016] In step S3, Server 1 calculates a reference value. Specifically, Server 1 uses AI analysis to calculate a corrected value by analyzing the interview information obtained in step S1 and the vital information obtained in step S2. Using this corrected value, Server 1 calculates an individual reference value (corrected WBGT reference value) for each worker. The individual worker reference value is a reference value that reflects each worker's physical condition, medical history, work intensity, clothing, heat acclimatization status, etc., in relation to the WBGT reference value. Furthermore, Server 1 calculates a heatstroke risk value from the difference between the WBGT value obtained in step S2 and the individual worker reference value (corrected WBGT reference value).

[0017] In step S4, server 1 performs alarm determination and transmission. Specifically, server 1 determines whether the heatstroke risk value calculated in step S3 exceeds a predetermined threshold. If the threshold is exceeded, server 1 outputs an alert. There are three types of alerts in this embodiment: a rest alarm, a yellow alarm, and a red alarm. A rest alarm is transmitted when the heatstroke risk value exceeds the first threshold, prompting worker SW to take a break. A yellow alarm is transmitted when the heatstroke risk value exceeds the second threshold, encouraging the suspension of work. A red alarm is transmitted when the heatstroke risk value exceeds the third threshold, encouraging the worker to seek medical attention. Server 1 transmits these alerts to the administrator terminal 2 and the worker's mobile terminal 3.

[0018] In this way, this service performs a series of processes from acquiring information upon arrival at work to collecting information during work, calculating standard values, and determining and issuing alarms, thereby reducing the burden on manager F regarding heatstroke prevention and enabling timely responses.

[0019] Regarding Server 1, it can acquire vital information from the wearable terminal, the worker's mobile terminal 3. As shown in Figure 1, each worker SW wears a smartwatch-shaped worker's mobile terminal 3, and vital information such as heart rate, blood oxygen saturation, and activity level is acquired in real time from these terminals. By acquiring vital information, Server 1 can calculate individual worker reference values ​​that reflect the physical condition of the worker SW in real time, enabling more accurate heatstroke prevention. At the timing when device information is collected periodically, Server 1 can perform real-time analysis of each worker SW's corrected WBGT reference value (the WBGT reference value corrected by a correction value (WBGT correction value)) and heatstroke risk value (the difference between the WBGT value and the corrected WBGT reference value).

[0020] Furthermore, Server 1 can acquire interview information obtained from interviewing Worker SW about at least some of the various physical conditions and work conditions of the Worker SW. As shown in Figure 1, the foreman at the work site carries a smartphone, which is the administrator terminal 2, and interviews each Worker SW about their condition upon arrival at work, inputs the information into the administrator terminal 2, and uploads it to Server 1. The interview information includes information about the worker's physical condition upon arrival at work, such as whether they drank alcohol the previous day or were sleep-deprived. Information about medical history includes whether the worker is over 65 years old, has a history of heart disease, has suffered from heatstroke in the past, suffers from heatstroke every year, experiences poor health in the summer, has high blood pressure, is obese or not exercises. Information about work intensity includes whether the worker is at rest, has a low metabolic rate, a moderate metabolic rate, a high metabolic rate, or a very high metabolic rate. Information about clothing includes work clothes, overalls, single-layer polyolefin, etc. Information about heat acclimatization includes whether the worker is accustomed to the heat. Server 1 can acquire information on the physical and work conditions of workers SW, and calculate individual worker reference values ​​(corrected WBGT reference values) that reflect the individual condition of each worker SW. The difference between this corrected WBGT reference value, which reflects the condition at the time of arrival at work, and the WBGT value can be managed as a heatstroke risk value. Specifically, for example, if the WBGT reference value is 32°C, the WBGT correction value is 5°C, and the WBGT value is 28°C, the corrected WBGT reference value becomes 27°C (WBGT reference value (32°C) - WBGT correction value (5°C) = 27°C), and the heatstroke risk value becomes WBGT value (28°C) - corrected WBGT reference value (27°C) = +1°C. In this example, since the heatstroke risk value is positive, it is managed as a high risk (if it is negative, the risk is low).

[0021] Furthermore, Server 1 can calculate a corrected value (WBGT corrected value) by AI-analyzing interview information and vital information. As shown in step S3 of Figure 1, Server 1 calculates the corrected value through AI analysis and calculates the individual worker standard value (corrected WBGT standard value). Specifically, Server 1 optimizes condition data such as thresholds, calculation formulas, and corrected values ​​by AI-analyzing the correlation between heatstroke risk values ​​and onset risk-related information based on information from multiple days and multiple work sites. Prevention risk-related information refers to interview information at the time of arrival at work, information on rest and fluid / salt replenishment during patrols, the value from the WBGT measuring device 4, and the value of steps, which is the activity level of the worker's mobile terminal 3. Onset risk-related information refers to the heart rate, blood oxygen saturation, activity level (steps), and physical condition information during patrols, all of which are from the worker's mobile terminal 3. By calculating the corrected value through AI analysis, it is possible to calculate a more accurate individual worker standard value, thereby improving the accuracy of heatstroke prevention. Server 1 can be optimized by modifying condition data such as thresholds, calculation formulas, and correction values, taking into account the risk of illness, in order to ensure a longer working time.

[0022] Furthermore, Server 1 can present one or more questions related to heatstroke prevention to the administrator terminal 2 of the foreman, who is Administrator F, and manage the foreman's answers. As shown in step S1 of Figure 1, Server 1 administers a short test to the foreman upon arrival at work. The short test questions are prioritized based on various acquired information, real-time analysis, and AI-analyzed information, ensuring that questions of importance to the foreman are presented. By presenting these questions, the knowledge and awareness of heatstroke prevention among the foreman, who is Administrator F, can be enhanced. Since the knowledge gained from the short test is likely to be effectively reflected in practical work, awareness of heatstroke prevention efforts will also increase.

[0023] Furthermore, Server 1 can weight each problem based on the aforementioned preventive risk-related information and onset risk-related information, and prioritize presenting high-risk problems. As shown in step S1 of Figure 1, Server 1 weights the problems through AI analysis and presents them preferentially. Specifically, Server 1 has an algorithm that weights each problem based on the results of AI analysis using preventive risk-related information and onset risk-related information of workers SW supervised and managed by the foreman, and prioritizes presenting high-risk problems, prioritizing problems that have not been cleared. By reflecting AI analysis results of facts occurring at the worksite, such as information gathered at the time of arrival, device information, and corrected WBGT standard values, as well as organizational policies and focus points at the worksite, in the weighting, Server 1 can prioritize presenting problems that correspond to the risk situation at the worksite. This allows Server 1 to effectively enable the acquisition of practical knowledge.

[0024] Furthermore, Server 1 can acquire images that include workers SW present at each work site, obtained from images captured by cameras 6 installed at each work site, as worker site images. As shown in Figure 1, cameras 6 are installed at work site A and work site B (only work site B is shown), and capture images of the work site's condition. By installing cameras 6 at each work site, Server 1 can grasp the condition of the work site through images. By acquiring images of the work site including workers SW using camera 7, Server 1 can visually grasp the condition of the work site.

[0025] Furthermore, Server 1 can output an alert if the heatstroke risk value exceeds a predetermined threshold. As shown in step S4 of Figure 1, Server 1 determines whether the heatstroke risk value has exceeded the threshold and outputs an alert if it has. Specifically, Server 1 issues a rest alarm if the WBGT value exceeds the corrected WBGT standard value by a threshold or more. In addition, Server 1 issues a yellow alarm to prompt work to be stopped if it exceeds an even higher threshold, or if device information or interview information exceeds each threshold. Furthermore, Server 1 issues a red alarm to prompt medical attention if it exceeds the threshold at which it is determined that heatstroke has occurred based on device information or interview information. When the heatstroke risk value exceeds each threshold, Server 1 contacts the administrator terminal 2 and the worker's mobile terminal 3 with a rest alarm, a yellow alarm to prompt work to be stopped, or a red alarm to prompt medical attention. By outputting an alert when the heatstroke risk value exceeds the threshold, Server 1 can prompt timely attention from the administrator F and the worker SW.

[0026] Furthermore, Server 1 can send worker site images as an alert, or along with an alert, to the foreman's administrator terminal 2 and the head office administrator terminal 2. Specifically, if any alarm occurs with respect to a particular worker SW, an image of the work site where the worker SW is located will be displayed on the foreman's administrator terminal 2 and the head office administrator terminal 2. By sending worker site images when an alarm occurs, Server 1 enables foremen and others to instantly grasp the status of the work site and take appropriate action.

[0027] Next, with reference to Figure 2, we will describe the configuration of an information processing system to which a server according to one embodiment of the information processing device of the present invention is applied, which enables the provision of the service described above. Figure 2 is a diagram showing an example of the configuration of an information processing system to which a server according to one embodiment of the information processing device of the present invention is applied.

[0028] The information processing system shown in Figure 2 is configured to include a server 1, an administrator terminal 2, worker mobile terminals 3-1 to 3-n (where n is an integer value of 1 or more), a WBGT measuring device 4, a gateway 5, and a camera 6. The server 1, administrator terminal 2, gateway 5, and camera 6 are interconnected via a network N such as the Internet. When it is not necessary to distinguish between individual worker mobile terminals 3-1 to 3-n, they are collectively referred to as worker mobile terminal 3.

[0029] Server 1 is an information processing device managed by the service provider of this service (Figure 1). Server 1 is a server that provides heatstroke prevention support services and performs various processes to realize this service while communicating as appropriate with the administrator terminal 2, worker mobile terminal 3, WBGT measuring device 4, gateway 5, and camera 6. Specifically, Server 1 calculates individual worker reference values ​​(corrected WBGT reference value (second reference value)) and heatstroke risk values ​​(third reference value) based on the WBGT value (first reference value) obtained from the WBGT measuring device 4, vital information obtained from the worker mobile terminal 3, interview information obtained from the administrator terminal 2, etc., and outputs an alert when the calculated heatstroke risk value exceeds a predetermined threshold.

[0030] The administrator terminal 2 is an information processing device operated by the foreman at the work site (work site A and work site B in Figure 1) or the head office administrator F, and is composed of a smartphone, tablet, personal computer, etc. While the administrator terminal 2 operated by the foreman is shown as a smartphone, it is not limited to this. The administrator terminal 2 communicates directly with the server 1 via the network N. The foreman uses the administrator terminal 2 to input information gathered from each worker SW upon arrival at work or during patrols, such as their physical condition, medical history, work intensity, clothing, and heat acclimatization status, and transmits this information to the server 1. The administrator terminal 2 also receives and displays heatstroke risk values ​​and alert information for each worker transmitted from the server 1. Furthermore, the administrator terminal 2 displays short quiz questions on heatstroke prevention distributed from the server 1, accepts the foreman's answers, and transmits them to the server 1.

[0031] The worker's mobile terminal 3 is a wearable device worn by the worker SW, and is composed of a smartwatch or the like. The worker's mobile terminal 3 measures vital information such as the worker SW's heart rate, blood oxygen saturation, and activity level (steps), and transmits it to the server 1 via Bluetooth® communication through the gateway 5. The worker's mobile terminal 3 also receives alerts such as rest alarms, yellow alarms, and red alarms transmitted from the server 1 and notifies the worker SW. Furthermore, the worker's mobile terminal 3 receives and displays WBGT values ​​and heatstroke risk values ​​transmitted periodically from the server 1, enabling the worker SW to understand their own condition.

[0032] The WBGT measuring device 4 is a temperature measuring device installed at the work site that measures the WBGT value, which is a heat index (work site heat index) used to evaluate heat stress caused by a hot environment. The WBGT value is a standard for evaluating heat stress in the work environment as defined by the American Conference of Governmental Industrial Hygienists (ACGIH) and the Japanese Industrial Standard JIS Z 8504. The WBGT measuring device 4 transmits the measured WBGT value to the server 1 via Bluetooth® communication through the gateway 5. The server 1 acquires this WBGT value as the first reference value.

[0033] Gateway 5 is a device that converts between Bluetooth® communication and mobile communication or Wi-Fi communication. Gateway 5 receives data transmitted via Bluetooth® communication from the worker's mobile terminal 3 and the WBGT measuring device 4, converts it to mobile communication or Wi-Fi communication, and transmits it to Server 1 via Network N. This makes it possible for the worker's mobile terminal 3 and the WBGT measuring device 4, which only support Bluetooth® communication, to communicate with Server 1 via Network N. Conversely, Gateway 5 converts data received from Server 1 via Network N to Bluetooth® communication and transmits it to the worker's mobile terminal 3. Note that if one or more gateways 5 are installed, for example, if multiple gateways 5 detect the worker's mobile terminal 3 of a certain worker SW, Server 1 can determine that the worker SW is near the gateway 5 with the strongest Bluetooth® signal and pinpoint the location of the worker SW.

[0034] Camera 6 is a camera installed at the work site that captures images of the work site. Camera 6 transmits the captured images of the work site to Server 1 via the network N using mobile communication or Wi-Fi communication. When various alarms occur at a specific worker SW, Server 1 transmits images of the work site where the worker SW is located to the supervisor's administrator terminal 2 and the head office administrator terminal 2, enabling instantaneous understanding of the work site's status. Camera 6 is not particularly limited, but it captures subjects within a 360-degree omnidirectional range. Camera 6 is installed at a height of 1.8m to 2.5m from the ground or floor. Here, the images of the work site captured and generated by Camera 6 are acquired as image data from the perspective of the supervisor or worker SW.

[0035] As shown in Figure 2, in the information processing system, the worker's mobile terminal 3 and the WBGT measuring device 4 are connected to the gateway 5 via Bluetooth® communication, and the gateway 5 is connected to the network N via mobile communication or Wi-Fi communication. On the other hand, the administrator terminal 2 and the camera 6 are directly connected to the network N via mobile communication or Wi-Fi communication. With this configuration, various information transmitted from each device is aggregated to the server 1 via the network N, and the server 1 can then perform various processes for preventing heatstroke.

[0036] Next, with reference to Figure 3, the hardware configuration of Server 1 in the information processing system shown in Figure 2 will be described. Figure 3 is a block diagram showing an example of the hardware configuration of Server 1 in the information processing system shown in Figure 2.

[0037] Server 1 comprises a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an input unit 16, an output unit 17, a storage unit 18, a communication unit 19, and a drive 20.

[0038] The CPU 11 executes various processes according to the program recorded in the ROM 12 or the program loaded from the storage unit 18 into the RAM 13. The CPU 11 functions as a central processing unit and implements each of the functional blocks shown in Figure 4 (WBGT value acquisition unit 51, worker site information acquisition unit 52, correction value calculation unit 53, individual worker standard value calculation unit 54, heatstroke risk value calculation unit 55, problem management unit 56, worker site image acquisition unit 57, alert output unit 58, AI analysis unit 59, etc.) as software. The RAM 13 also appropriately stores data necessary for the CPU 11 to execute various processes.

[0039] The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14. An input unit 16, an output unit 17, a storage unit 18, a communication unit 19, and a drive 20 are connected to the input / output interface 15.

[0040] The input unit 16 is configured, for example, with a keyboard, and takes in various types of information. The output unit 17 is configured with a display such as an LCD or a speaker, and outputs various types of information as images or sounds. The storage unit 18 is configured with DRAM (Dynamic Random Access Memory) or the like, and stores various types of data. The storage unit 18 stores various databases shown in Figure 4, which will be described later (worker DB 71, WBGT information DB 72, interview information DB 73, vital information DB 74, correction value DB 75, standard value / risk value DB 76, problem / answer DB 77, worker site image DB 78, alert history DB 79, AI learning data DB 80, site / organization information DB 81, etc.). The communication unit 19 communicates with other devices (for example, the administrator terminal 2, gateway 5, and camera 6 in Figure 2) via a network N including the Internet.

[0041] A removable media 21, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately mounted on the drive 20. Programs read from the removable media 21 by the drive 20 are installed in the storage unit 18 as needed. The removable media 21 can also store various types of data stored in the storage unit 18, just like the storage unit 18.

[0042] Although not shown in the diagram, the administrator terminal 2, worker mobile terminal 3, WBGT measuring device 4, gateway 5, and camera 6 in Figure 2 can also have a configuration that is basically the same as the hardware configuration shown in Figure 3. However, the components of the worker mobile terminal 3 and WBGT measuring device 4 may be simplified in order to make them smaller and more power-efficient as wearable terminals and measuring devices. Therefore, a detailed explanation of the hardware configuration of the administrator terminal 2, worker mobile terminal 3, WBGT measuring device 4, gateway 5, and camera 6 will be omitted.

[0043] Through the cooperation of various types of hardware and various types of software that constitute the information processing system of FIG. 2 including the server 1 of FIG. 3, various types of processing for providing the service of FIG. 1 can be executed.

[0044] Next, the functional configuration of the server 1 of FIG. 3 in the information processing system of FIG. 2 will be described with reference to FIG. 4. FIG. 4 is a functional block diagram showing an example of the functional configuration of the server of FIG. 3 in the information processing system of FIG. 2.

[0045] As shown in FIG. 4, in the CPU 11 of the server 1, a WBGT value acquisition unit 51, a worker site information acquisition unit 52, a correction value calculation unit 53, an individual worker reference value calculation unit 54, a heat stroke risk value calculation unit 55, a problem management unit 56, a worker site image acquisition unit 57, an alert output unit 58, and an AI analysis unit 59 function. Furthermore, in one area of the storage unit 18 of the server 1, a worker DB 71, a WBGT information DB 72, an interview information DB 73, a vital information DB 74, a correction value DB 75, a reference value / risk value DB 76, a problem / answer DB 77, a worker site image DB 78, an alert history DB 79, an AI learning data DB 80, and a site / organization information DB 81 are provided.

[0046] The WBGT value acquisition unit 51 acquires a first reference value at a work site where a worker SW is present (work site A and work site B in FIG. 1), with a standard related to work environments defined by a predetermined official standard-setting organization used as a first reference. Specifically, the WBGT value acquisition unit 51 acquires the WBGT value measured by the WBGT measurement device 4 transmitted from the gateway 5 via the communication unit 19. The WBGT value is an official standard for evaluating heat stress in work environments defined by the American Conference of Governmental Industrial Hygienists (ACGIH) and Japanese Industrial Standard JIS Z 8504. The WBGT value acquisition unit 51 stores the acquired WBGT value in the WBGT information DB 72. This enables acquisition of an objective reference value related to the environmental temperature of the work site.

[0047] The worker on-site information acquisition unit 52 acquires, as worker on-site information, information related to a combination of one or more states among a plurality of types of physical states of a worker SW present at a work site and a plurality of types of work states. Specifically, the worker on-site information acquisition unit 52 acquires vital information such as heart rate, blood oxygen saturation, and activity amount (number of steps) acquired from a worker mobile terminal 3 (wearable terminal) worn by the worker SW. In addition, the worker on-site information acquisition unit 52 acquires interview information transmitted from the administrator terminal 2 via the communication unit 19, which is obtained as a result of the foreman conducting an interview with the worker SW. The interview information includes physical condition at the time of going to work, medical history, work intensity, clothing, heat acclimation status, and the like. The worker on-site information acquisition unit 52 stores information for uniquely identifying the worker SW in the worker DB 71, stores the acquired vital information in the vital information DB 74, and further stores the interview information in the interview information DB 73. This allows the server 1 to collect information on the individual physical state and work state of each worker SW.

[0048] The correction value calculation unit 53 performs AI analysis on the interview information and the vital information to calculate a correction value. Specifically, the correction value calculation unit 53 cooperates with the AI analysis unit 59 to perform AI analysis on the interview information stored in the interview information DB 73 and the vital information stored in the vital information DB 74, and calculates a correction value for the WBGT reference value (WBGT correction value). In addition, the correction value calculation unit 53 calculates a correction value (WBGT correction value) for correcting the WBGT reference value based on each factor such as physical condition at the time of going to work, medical history, work intensity, clothing, and heat acclimation status. In addition, the correction value calculation unit 53 optimizes the correction value by performing AI analysis on the correlation between the heat stroke risk value and the onset risk-related information based on a plurality of days of on-site information. The correction value calculation unit 53 stores the calculated correction value (WBGT correction value) in the correction value DB 75. This allows the server 1 to obtain a correction value (WBGT correction value) for calculating a more accurate individual worker reference value (corrected WBGT reference value).

[0049] The worker-specific standard value calculation unit 54 calculates a second standard value for worker SW present at the work site based on worker site information, using a standard indicating the degree of a person's tolerance to the work environment as the second standard. Specifically, the worker-specific standard value calculation unit 54 calculates a worker-specific standard value (corrected WBGT standard value) by performing a predetermined calculation on the WBGT standard value stored in the WBGT information DB 72 using the correction value (WBGT correction value) stored in the correction value DB 75. This worker-specific standard value is a standard value indicating the degree of tolerance to the work environment for each worker SW, reflecting their physical condition, medical history, work intensity, clothing, heat acclimatization status, etc. The worker-specific standard value calculation unit 54 stores the calculated worker-specific standard value in the standard value / risk value DB 76. This allows the server 1 to calculate a second standard value that reflects the individual status of each worker SW.

[0050] The heatstroke risk value calculation unit 55 uses a third criterion to indicate the degree of heatstroke risk for each worker SW present at the worksite, and calculates the third criterion value for each worker SW based on the difference between the first criterion value and the second criterion value. Specifically, the heatstroke risk value calculation unit 55 calculates the difference between the WBGT value (first criterion value) stored in the WBGT information DB 72 and the individual worker criterion value (corrected WBGT criterion value (second criterion value)) stored in the criterion value / risk value DB 76, and calculates this difference value as the heatstroke risk value (third criterion value). The heatstroke risk value serves as an indicator that quantitatively shows the degree of heatstroke risk for each worker SW at present. The heatstroke risk value calculation unit 55 stores the calculated heatstroke risk value in the criterion value / risk value DB 76. As a result, Server 1 can respond to complex heatstroke prevention measures that previously required considering various pieces of information, based on the heatstroke risk value (in other words, it can respond based on the heatstroke risk value), and consequently, it can respond more quickly.

[0051] The Problem Management Unit 56 presents one or more questions related to heatstroke prevention to the terminal (administrator terminal 2) of the administrator F (foreman) and manages the administrator F's answers. Specifically, the Problem Management Unit 56 presents a short test question on heatstroke prevention to the administrator terminal 2 via the communication unit 19, receives the foreman's answers transmitted from the administrator terminal 2, and stores and manages the answer results in the Question / Answer DB 77. In addition, the Problem Management Unit 56 works in cooperation with the AI ​​analysis unit 59 to weight each question based on prevention risk-related information and onset risk-related information, and prioritizes presenting questions with a high risk. Prevention risk-related information refers to interview information at the time of arrival at work, information on rest and fluid / salt replenishment during patrols, the value of the WBGT measuring device 4, and the value of steps taken, which is activity, from the worker's mobile terminal 3. Onset risk-related information refers to the heart rate, blood oxygen saturation, activity level (steps taken), and physical condition information during patrols from the worker's mobile terminal 3. This allows Server 1 to enhance the foreman's knowledge and awareness regarding heatstroke prevention, and to effectively enable the acquisition of practical knowledge by prioritizing questions that correspond to the risk situation at the work site.

[0052] The worker site image acquisition unit 57 acquires images that include workers SW present at the work site, obtained from images captured by the camera 6 installed at the work site, as worker site images. Specifically, the worker site image acquisition unit 57 acquires worker site images transmitted from the camera 6 via the communication unit 19 and stores them in the worker site image DB 78. This allows the server 1 to visually grasp the state of the work site.

[0053] The alert output unit 58 outputs an alert when the third reference value exceeds a predetermined threshold. Specifically, the alert output unit 58 determines whether the heatstroke risk value (third reference value) stored in the reference value / risk value DB 76 exceeds a predetermined threshold. If the WBGT value exceeds the corrected WBGT reference value by a first threshold or more, the alert output unit 58 issues a rest alarm. Furthermore, if the WBGT value exceeds an even higher second threshold, or if device information or interview information exceeds each threshold, the alert output unit 58 issues a yellow alarm to prompt work to be interrupted. In addition, if the device information or interview information exceeds a third threshold in which heatstroke is judged to have occurred, the alert output unit 58 issues a red alarm to prompt medical attention. The alert output unit 58 stores the issued alerts in the alert history DB 79. The alert output unit 58 also sends worker site images stored in the worker site image DB 78 to the administrator terminal 2 as an alert, or together with the alert. This allows server 1 to promptly alert administrator F (foreman) and worker SW, instantly grasp the status of the work site, and take appropriate action.

[0054] The AI ​​analysis unit 59 works in cooperation with the correction value calculation unit 53 and the problem management unit 56 to perform AI analysis. Specifically, the AI ​​analysis unit 59 stores information related to prevention risks and onset risks for multiple foremen and multiple workers (SW) at multiple work sites of multiple organizations in the AI ​​learning data DB 80. Then, by performing AI analysis on this data, the AI ​​analysis unit 59 modifies and optimizes condition data such as thresholds, calculation formulas, and correction values ​​that can secure longer working hours while taking onset risks into consideration. As a result, the server 1 can perform real-time analysis of the corrected WBGT standard value and heatstroke risk value for each worker (SW) at the timing when device information is collected periodically. The information regarding the multiple work sites of the multiple organizations mentioned above is stored in the site / organization information DB 81.

[0055] Next, with reference to Figure 5, an example of the overall system implementation of the embodiment shown in Figures 1 to 4 will be described. Figure 5 is a representative drawing showing an example of the overall system implementation of the embodiment shown in Figures 1 to 4.

[0056] Figure 5 shows the internal configuration of Server 1, the arrangement of each device at multiple work sites (Work Site A, Work Site B, Work Site C), and the connection relationship with the administrator PC (Administrator Terminal 2) installed at the head office, etc. Functionally, Server 1 is shown as being divided into multiple CPUs and multiple memory units. Specifically, Server 1 comprises CPU 11-1, CPU 11-2, CPU 11-3, memory unit 18-1, memory unit 18-2, and memory unit 18-3.

[0057] CPU 11-1 includes functional units corresponding to the listening information monitoring unit, device information monitoring unit, real-time analysis unit, AI analysis unit, alarm activation unit, work IN / work in progress screen display unit, and dashboard (history) display unit. Storage unit 18-1 includes listening results / device information DB, real-time analysis / AI analysis results DB, alarm activation history DB, threshold / calculation formula / correction value condition data DB, worker DB, and site DB. CPU 11-2 includes a device information acquisition unit. Storage unit 18-2 includes a communication information DB and a communication pattern data DB. CPU 11-3 includes a skills (quiz at work) monitoring unit and an AI analysis unit for optimizing question presentation. Storage unit 18-3 includes a skills (quiz results) DB and a quiz material DB.

[0058] The above-mentioned listening information monitoring unit of the CPU 11-1 has the function of acquiring the listening results from the worker SW entered into the administrator terminal 2 in real time and storing them in the listening results / device information DB of the storage unit 18-1. The listening information includes information such as the worker's physical condition when coming to work (whether they drank alcohol yesterday, whether they were sleep-deprived, etc.), medical history (65 years of age or older, history of heart disease, past heatstroke, heatstroke every year, poor health in summer, high blood pressure, obesity or lack of exercise, etc.), work intensity and content (rest, low metabolic rate, moderate metabolic rate, high metabolic rate, extremely high metabolic rate, etc.), clothing (work clothes, overalls, single-layer polyolefin, etc.), and heat acclimatization (whether they are used to the heat, etc.).

[0059] The device information monitoring unit of CPU 11-1 periodically acquires information from the WBGT measuring device 4 and the worker's mobile terminal 3 approximately once every 10 minutes (this can be changed by setting), and stores it in the listening results / device information DB of the storage unit 18-1. Specifically, the device information monitoring unit acquires vital information such as heart rate, blood oxygen saturation, and activity level (steps) from the worker's mobile terminal 3. The device information monitoring unit also acquires the WBGT value of the work site from the WBGT measuring device 4. This information is transmitted to the server 1 via the gateway 5.

[0060] The real-time analysis unit of CPU 11-1 has the function of performing real-time analysis using the threshold, calculation formula, correction value, and other condition data stored in the threshold, calculation formula, and correction value condition data DB of the memory unit 18-1 based on the acquired information, and storing the results in the real-time analysis / AI analysis results DB. Specifically, the real-time analysis unit calculates the individual corrected WBGT standard value (individual worker standard value) for each worker from the interview information and device information. The real-time analysis unit also calculates the heatstroke risk value from the difference between the WBGT value at the work site and the corrected WBGT standard value.

[0061] The AI ​​analysis unit of CPU 11-1 has the function of analyzing the relationship between preventive risk-related information used for preventive measures and onset risk-related information treated as result information, and optimizing condition data such as thresholds, calculation formulas, and correction values ​​used for preventive risk measures. Specifically, the AI ​​analysis unit optimizes condition data such as thresholds, calculation formulas, and correction values ​​by performing AI analysis on the correlation between heatstroke risk values ​​and onset risk-related information based on information from multiple days and multiple sites. The preventive risk-related information here refers to interview information taken when employees arrive at work, information on rest and fluid / salt replenishment during patrols, WBGT values ​​obtained from the WBGT measuring device 4, and activity (step count) values ​​obtained from the worker's mobile terminal 3. The onset risk-related information refers to heart rate, blood oxygen saturation, activity level (step count) obtained from the worker's mobile terminal 3, and physical condition information during patrols. By calculating correction values ​​through AI analysis, more accurate individual worker standard values ​​can be calculated, improving the accuracy of heatstroke prevention.

[0062] The alarm emitter of CPU 11-1 has a function to output an alert when the heatstroke risk value exceeds a predetermined threshold. Specifically, the alarm emitter emits three types of alarms: a rest alarm, a yellow alarm, and a red alarm. The rest alarm is emitted when the WBGT value exceeds the first threshold above the corrected WBGT standard value, prompting the worker to take a break. The yellow alarm is emitted when it exceeds an even higher second threshold, or when device information or interview information exceeds each threshold, prompting the worker to stop working. The red alarm is emitted when it exceeds a third threshold, which is determined to indicate that heatstroke has occurred based on device information or interview information, prompting the worker to seek medical attention. These alarms are displayed on the administrator terminal 2 and the worker's mobile terminal 3.

[0063] The above-mentioned "Job In" and "Job In" screen display unit of CPU 11-1 has the function of displaying the "Job In" screen and "Job In" screen, which will be described later, on the administrator terminal 2. The "Job In" screen is a screen for the foreman to input interview information for each worker when they report to work (see Figure 7). The "Job In" screen is a screen for monitoring the status of each worker in real time while they are working (see Figures 10 and 11). The "Job In" screen displays the corrected WBGT standard value for each worker SW, the WBGT value of the work site, the heatstroke risk value, vital information, rest and hydration status, etc.

[0064] The dashboard (history) display unit of CPU 11-1 has the function of displaying past historical data in a dashboard format. Specifically, the dashboard (history) display unit displays data such as information acquired and calculated results at each work site, real-time analysis results, AI analysis results, corrected WBGT standard values ​​for each worker, the status of WBGT values ​​at the work site, the occurrence status of various alarms, and the knowledge and awareness status of the foreman on the administrator terminal 2. This allows multiple site managers to work towards optimizing each work site as a whole.

[0065] The device information acquisition and management unit of the CPU 11-2 has the function of managing the acquisition of device information transmitted from the worker's mobile terminal 3 and the WBGT measuring device 4. Specifically, the device information acquisition and management unit identifies and organizes the information from each device transmitted via the gateway 5. The device information acquisition and management unit also has the function of monitoring the connection status of devices and detecting communication errors and device malfunctions.

[0066] The Skill (Attendance Quiz) Monitoring Unit of CPU 11-3 has the function of issuing a short quiz on heatstroke prevention to the foreman and managing the answer results. Specifically, the Skill (Attendance Quiz) Monitoring Unit displays the quiz questions on the foreman's administrator terminal 2 when they arrive at work and accepts the foreman's answers. The quiz questions are selected from the quiz material DB in the memory unit 18-3. The Skill (Attendance Quiz) Monitoring Unit stores the foreman's answer results in the Skill (Quiz Results) DB in the memory unit 18-3 and analyzes the correct answer rate and level of understanding. The Skill (Attendance Quiz) Monitoring Unit also outputs the answer results to the administrator terminal 2 for each foreman in the form of tables and graphs. Furthermore, the Skill (Attendance Quiz) Monitoring Unit also outputs the average values ​​for the work site and the organization to the administrator terminal 2.

[0067] The AI ​​analysis unit for optimizing question presentation in CPU 11-3 has the function of weighting each question based on preventive risk-related information and onset risk-related information, and prioritizing the presentation of high-risk questions. Specifically, the AI ​​analysis unit for optimizing question presentation weights each question based on the results of AI analysis using preventive risk-related information and onset risk-related information of workers (SWs) supervised and managed by the foreman. The AI ​​analysis unit for optimizing question presentation has an algorithm that prioritizes the presentation of high-risk questions, and prioritizes questions that have not been answered correctly. The weighting reflects AI analysis results of facts occurring at the worksite, such as information gathered during attendance, device information, and corrected WBGT standard values, as well as organizational policies and focus points at the worksite. This makes it possible to prioritize the presentation of questions that correspond to the risk situation at the worksite, and to effectively acquire practical knowledge.

[0068] At work site A, a supervisor terminal 2 carried by the foreman, a gateway 5, a WBGT measuring device 4, and worker mobile terminals 3-1, 3-2, and 3-3 worn by multiple worker SWs are arranged. Worker mobile terminals 3-1, 3-2, and 3-3 are smartwatches worn by each worker SW, and acquire vital information such as heart rate, blood oxygen saturation, and activity level (steps). This vital information is transmitted to gateway 5 via Bluetooth® communication. The WBGT measuring device 4 measures the WBGT value (heat index) at work site A and transmits the measurement result to gateway 5 via Bluetooth® communication. Gateway 5 has the function of collecting information from multiple devices with a single unit, and converts the information received from worker mobile terminals 3-1, 3-2, 3-3 and the WBGT measuring device 4 from Bluetooth® communication to mobile communication or Wi-Fi and transmits it to server 1 via network N. Gateway 5 also has the function of sending alarms to each worker mobile terminal 3 and the function of determining the distance to the location of the device. One or more gateways 5 are installed, and for example, if multiple gateways 5 detect a worker SW's worker mobile terminal 3, server 1 can determine that the worker SW is near the gateway 5 with the strongest Bluetooth® signal strength and pinpoint the location of the worker SW.

[0069] Administrator terminal 2 is an information processing terminal such as a smartphone used by the foreman. The foreman inputs information gathered from workers, such as their physical condition upon arrival at work, medical history, work intensity, clothing, and heat acclimatization, and transmits it to server 1 via network N through mobile communication or Wi-Fi. Administrator terminal 2 also receives and displays various screen data from server 1, such as the "Job IN" screen and the "Job In" screen. Furthermore, administrator terminal 2 displays quiz questions for the foreman and transmits the foreman's answers to server 1.

[0070] Work sites B and C have the same configuration as work site A. Specifically, work site B is equipped with a gateway 5, a WBGT measuring device 4, and a worker's portable terminal 3 worn by the worker SW. Work site C is also equipped with a gateway 5, a WBGT measuring device 4, and a worker's portable terminal 3 worn by the worker SW.

[0071] The service provider's PC (administrator terminal 2) and the administrator's PC (administrator terminal 2), shown on the right side of Figure 5, are installed at the head office or other locations and are connected to server 1 via a network N such as the internet. They comprehensively manage various information from multiple work sites A, B, and C. Administrator terminal 2 displays data such as information acquired and calculated results from each work site, real-time analysis results, AI analysis results, corrected WBGT reference values ​​for each worker SW, the status of WBGT values ​​at the work site, the occurrence status of various alarms, and the knowledge and awareness status of foremen. This allows multiple site managers (foremen) to take steps to optimize each work site as a whole.

[0072] As shown in Figure 5, this service is implemented by a system in which multiple work sites A, B, and C and an administrator terminal 2 are connected via a network N, with server 1 at the center. Within each work site A, B, and C, worker mobile terminals 3 and WBGT measuring devices 4 are connected to gateway 5 via Bluetooth® communication, and gateway 5 is connected to network N via mobile communication or Wi-Fi.

[0073] With this configuration, using the CPU 11-1 of server 1 as a representative example, the listening information monitoring unit of the CPU 11-1 stores the listening results / device information DB of the storage unit 18-1 as needed, based on the listening results from the worker SW input to the administrator terminal 2. In addition, the device information monitoring unit of the CPU 11-1 periodically acquires information from the WBGT measuring device 4 and the worker's mobile terminal 3 approximately once every 10 minutes (this can be changed by setting) and stores it in the listening results / device information DB of the storage unit 18-1.

[0074] Simultaneously, the real-time analysis unit of the CPU 11-1 performs real-time analysis based on the acquired information, using the threshold, calculation formula, correction value, and other condition data stored in the threshold, calculation formula, and correction value condition data DB of the memory unit 18-1, and stores the results in the real-time analysis / AI analysis DB. Then, the job IN / job in progress screen display unit displays the job in progress screen and dashboard (history) screen on the administrator terminal 2.

[0075] Furthermore, the AI ​​analysis unit of CPU 11-1 analyzes the relationship between preventive risk-related information used for preventive measures and onset risk-related information treated as result information, and optimizes condition data such as thresholds, calculation formulas, and correction values ​​used for preventive risk measures. Here, preventive risk-related information refers to interview information taken when employees arrive at work, information on breaks and fluid / salt intake during patrols, WBGT values ​​obtained from WBGT measuring device 4, and activity (step count) values ​​obtained from worker mobile terminal 3. Onset risk-related information refers to heart rate, blood oxygen saturation, activity level (step count), and physical condition information during patrols obtained from worker mobile terminal 3.

[0076] Furthermore, the alarm emitter of CPU 11-1 emits break alarms, yellow alarms, and red alarms. These alarms are displayed on the administrator terminal 2 and the worker's mobile terminal 3.

[0077] In this way, the system configuration shown in Figure 5 makes it possible to realize the service flow shown in Figure 1.

[0078] Next, with reference to Figure 6, the Top screen and the screen displayed when an alarm occurs on the administrator terminal 2 will be explained. Figure 6 is a diagram showing the Top screen and the screen displayed when an alarm occurs on the administrator terminal according to the embodiment shown in Figures 1 to 5.

[0079] Of the three screens shown in Figure 6, the leftmost screen displays the normal Top screen. The center screen displays the Top screen when a break alarm is triggered, and the rightmost screen displays the Top screen when a yellow alarm or red alarm is triggered. When the foreman (administrator F) arrives at work, he logs into the dedicated application software (app) on administrator terminal 2 and opens the Top screen. The Top screen is displayed on the display (output unit, display unit) of administrator terminal 2 and is the starting point for the foreman to use this service. On the left Top screen, the date and time (for example, "February 1, 2025 (Saturday)" and "10:06") are displayed at the top of the screen. Below that, the name of the work site (for example, "Yokohama No. 1 Site") and the user name (for example, "Taro Sato") are displayed.

[0080] Multiple buttons are located in the center of the screen. Specifically, there are buttons for "Start Work," "Currently Working," and "5-Minute e-Learning Material." The "Start Work" button also displays the start time (for example, "07:30"). By pressing the "Start Work" button on the Top screen, the foreman transitions to the "Start Work" screen shown in Figure 7 (described later), where they can check the work status of each worker SW and input information such as their physical condition upon arrival, medical history, work intensity, clothing, and heat acclimatization status into their smartphone (administrator terminal 2). By pressing the "Currently Working" button, the foreman transitions to the "Currently Working" screen shown in Figure 10 (described later), where they can monitor the status of each worker SW during work.

[0081] The central screen shows the Top screen when a break alarm occurs. In addition to the normal Top screen, this screen displays "Break Alarm 1 Activated" in the center. The break alarm is an alarm issued by the alarm emitter of CPU 11-1 in Figure 5, and occurs when the WBGT value shown in Figure 17 exceeds a predetermined threshold (e.g., about 1°C) from the corrected WBGT reference value, and the period without a break continues for a predetermined time (e.g., 15 minutes) or longer. The display of this break alarm allows the foreman to instruct the worker SW in question to take a break immediately. The break alarm is displayed in a different color from the normal display (e.g., light pink), making it easy for the foreman to recognize it visually.

[0082] The screen on the right shows the top screen when a yellow alarm or red alarm occurs. On this screen, multiple alarm displays such as "Yellow Alarm 1 Activated," "Yellow Alarm 2 Activated," and "Red Alarm 1 Activated" are added. A yellow alarm is an alarm activated by the alarm emitter of CPU 11-1 in Figure 5, and is activated when the WBGT value shown in Figures 17 and 18 exceeds a high threshold (e.g., 4°C or higher) from the corrected WBGT standard value, or when vital information (heart rate, blood oxygen saturation) obtained from the worker's mobile terminal 3 exceeds a predetermined threshold, or when signs of poor health (dizziness, fainting, headache, nausea, fatigue, etc.) are confirmed in the information gathered during patrols. A yellow alarm is an alarm that prompts the interruption of work. A red alarm, as shown in Figure 5, is an alarm issued by the alarm emitter of CPU 11-1. It is triggered when the blood oxygen saturation level obtained from the worker's portable terminal 3 shown in Figure 18 is extremely low (for example, below 79%), or when signs of serious illness (impaired consciousness, convulsions, motor impairment) are confirmed in the information gathered during patrols. The red alarm is an alarm that prompts the worker to seek medical attention.

[0083] Yellow and red alarms are displayed in different colors (for example, yellow for yellow alarms and red for red alarms), allowing supervisors to easily visually recognize the type and urgency of the alarm. If all three types of alarms (break alarm, yellow alarm, and red alarm) occur simultaneously, they will be issued and displayed in the following order of priority: break alarm < yellow alarm < red alarm.

[0084] As shown in Figure 6, the Top screen and the screen displayed when an alarm occurs allow the foreman to access various functions of this service and to easily recognize the alarm that has occurred visually and take appropriate action. This service reduces the burden on administrator F regarding heatstroke prevention and enables timely responses.

[0085] While the above uses the app user as the foreman, this definition is not limited to this; it also includes supervisors, head office managers, and remote site managers.

[0086] Next, the Job IN screen displayed on the administrator terminal 2 will be explained with reference to Figure 7. Figure 7 is a diagram showing the Job IN screen displayed on the administrator terminal in the embodiment shown in Figures 1 to 6.

[0087] The foreman (manager F) presses the "Job IN" button on the Top screen in Figure 6, which transitions to the Job IN screen in Figure 7. On the Job IN screen, the foreman confirms the work status of each worker SW and also gathers information on their physical condition upon arrival at work, medical history, work intensity, clothing, heat acclimatization, etc., and inputs this information into the manager terminal 2. This information is sent to the server 11-1 in Figure 5 and stored in the interview results / device information DB of the storage unit 18-1.

[0088] Next, referring to Figure 8, we will explain the selection items for health condition and medical history at the time of arrival at work, which are entered on the Job IN screen in Figure 7. Figure 8 is a diagram showing the selection items for health condition and medical history at the time of arrival at work, which are entered on the Job IN screen in Figure 7.

[0089] In Figure 8, the top section shows a table of options for selecting one's physical condition upon arrival at work. The options include columns for No., physical condition (working, not attending work, no consideration needed, consideration needed, feeling unwell), self-awareness (not aware, hangover, upset stomach, feeling feverish, feeling unwell), and alcohol consumption (did not drink yesterday, drank yesterday, drank too much, slept less than 5 hours, did not consume fluids or salt at breakfast). On the right side of Figure 8, a numbered list shows options for selecting one's medical history. These options include (1) being 65 years of age or older, (2) having a history of heart disease, (3) having suffered from heatstroke in the past, (4) suffering from heatstroke every year, (5) feeling unwell during the summer, (6) having high blood pressure, and (7) being obese or not exercising. The bottom section of Figure 8 shows a table of options for selecting one's work content, with columns for No., work intensity, clothing, and heat acclimatization. The interview information entered based on these selections will be used to calculate the second baseline (adjusted WBGT baseline).

[0090] Next, with reference to Figure 9, the quiz questions and answer screens displayed on the administrator terminal 2 will be explained. Figure 9 shows the quiz questions and answer screens displayed on the administrator terminal for the embodiment shown in Figures 1 to 8.

[0091] The foreman (manager F) moves to the quiz screen in Figure 9 by pressing the "Next" button on the Job IN screen in Figure 7. The quiz consists of short sentences like a quiz, and explanations are displayed even if the answer is incorrect. In Figure 9, the question screen is shown on the left and the answer screen is shown on the right. The number of questions in the quiz can be changed in the settings, but about three questions is appropriate. After the test is completed, the user returns to the Top screen in Figure 6. Note that the settings can be configured so that the user does not proceed to the next Job In progress screen unless this quiz is completed, in which case the foreman will always complete the quiz.

[0092] Next, the "Work in Progress" screen displayed on the administrator terminal 2 will be described with reference to Figures 10 and 11. Figure 10 is a diagram showing the "Work in Progress" screen displayed on the administrator terminal according to the embodiment shown in Figures 1 to 9. Figure 11 is a detailed enlarged view of the upper left part of the "Work in Progress" screen in Figure 10.

[0093] When work begins, the foreman (manager F) presses the "Working" button on the manager terminal 2 to display the "Working" screen shown in Figure 10. The "Working" screen displays the WBGT value for each work site, the location of each worker SW, and the heatstroke risk value (third reference value) for each worker SW at regular intervals. If an alarm is triggered, the alarm status is also displayed in color. The "Working" screen is structured in a table format and displays records of worker No., Name, work site, physical condition, and rest / hydration for each patrol time (physical condition: heat syncope such as pale face, dehydration, nausea, dizziness, lightheadedness, acute muscle pain, and muscle cramps; heat exhaustion such as dry mouth, dizziness, headache, irritability, and fatigue; heatstroke such as unconsciousness, seizures, and feeling hot). In addition, the WBGT value obtained from the WBGT measuring device 4 is automatically entered. The foreman interviews each worker (SW) about their physical condition during work, as well as their rest, hydration, and salt intake, and enters this information into administrator terminal 2. The screen displays "CSV output" and "Check sheet PDF output" buttons.

[0094] Figure 11 shows worker information (No., Name, Site), patrol time, WBGT value obtained from WBGT measuring device 4, corrected WBGT reference value, alarm occurrence status, physical condition selection items, and rest / hydration / salt replenishment selection items. In addition, the detailed data display area that appears when clicked shows the corrected WBGT reference value, heart rate, blood oxygen, exercise level, physical condition at the time of arrival at work, medical history, work intensity, clothing, and heat acclimatization obtained from worker's mobile terminal 3.

[0095] Next, referring to Figure 12, we will explain the implementation details for preventing heatstroke as outlined in the "Basic Guidelines for Preventing Heatstroke in the Workplace" formulated by the Ministry of Health, Labour and Welfare. Figure 12 is a diagram showing the implementation details for preventing heatstroke as outlined in the "Basic Guidelines for Preventing Heatstroke in the Workplace" formulated by the Ministry of Health, Labour and Welfare. This service supports the implementation of the details shown in Figure 12 so that the supervisor (manager F) can carry them out in a timely and efficient manner.

[0096] Next, referring to Figure 13, we will explain the relationship between the measures taken to prevent heatstroke and the support provided by the heatstroke prevention support service. Figure 13 is a diagram showing the relationship between the measures taken to prevent heatstroke and the support provided by the heatstroke prevention support service in this embodiment shown in Figures 1 to 12.

[0097] As shown in Figure 13, the implementation details for heatstroke prevention measures and the content of the heatstroke prevention support service are organized into three steps (1st, 2nd, and 3rd). In the 1st step, occupational health education is conducted as part of the implementation details for heatstroke prevention measures. As part of the heatstroke prevention support service, Server 1 stores visualization information on foreman skills. On the foreman (administrator F) side, using administrator terminal 2, foremen improve their "knowledge" and "awareness" by taking a short test on heatstroke prevention upon arrival at work.

[0098] In the second step, as part of the measures to prevent heatstroke, the condition of workers (SWs) will be checked before work begins. Specifically, the following items will be checked: a. physical condition upon arrival at work, b. medical history, c. work intensity, f. clothing, and g. heat acclimatization. In addition, the WBGT value of each work area will be determined, and improvements to the work area and revisions to the work content will be made. Furthermore, work time management will be implemented in accordance with the WBGT value and the condition of each worker (SW). In addition, patrols will be continuously conducted during work to check the condition of the workers. Specifically, their physical condition (health status (heat syncope such as pale face, dehydration, nausea, dizziness, lightheadedness, acute muscle pain, and cramps; heat exhaustion such as dry mouth, dizziness, headache, irritability, and fatigue; heatstroke such as unconsciousness, seizures, and feeling hot)), and rest and hydration status will be checked.

[0099] The heatstroke prevention support service includes the following steps: On the foreman's side, using administrator terminal 2, the foreman checks each worker's medical history and physical condition during the morning meeting and inputs the information into administrator terminal 2. A WBGT measuring device 4 is installed at each work site, and the WBGT value is automatically displayed on the foreman's administrator terminal 2. The foreman periodically speaks to each worker SW and inputs the results into administrator terminal 2. The input includes physical condition, rest and hydration status, and the results of the foreman's verbal checks. On the worker SW side, all workers wear worker mobile terminals 3 to collect vital information during work. This vital information includes heart rate, blood oxygen, and activity (steps) values. Furthermore, on the server side, WBGT correction calculations are performed as real-time analysis, and rest alarms are generated. Also, the results of the foreman's verbal checks are saved.

[0100] In the third step, as part of the heatstroke prevention measures, appropriate action will be taken if symptoms suggestive of heatstroke appear. As part of the heatstroke prevention support service, a yellow alarm will be issued for workers whose prevention risk value has worsened, and this will be displayed on the supervisor's terminal 2 and the worker's mobile terminal 3. The yellow alarm is intended to prompt workers to stop work or take a break.

[0101] In this way, the relationship between the heatstroke prevention measures implemented by the foreman and the content of the heatstroke prevention support service becomes clear. It can be seen that the service processes information from the administrator terminal 2, the WBGT measuring device 4, and the worker's mobile terminal 3 at each of the 1st to 3rd stages and distributes alarms. This information and action results are stored on server 1. Furthermore, the service allows for the output of daily heatstroke prevention check sheet information in CSV format, enabling objective understanding and comparison of the situation at all work sites, thus facilitating operational optimization and continuous improvement of the quality of countermeasures. Moreover, by using this service, the heatstroke prevention check sheet, which was previously handwritten, can be output as a PDF, reducing the burden on the foreman.

[0102] Next, we will explain the heatstroke prevention checklist with reference to Figure 14. Figure 14 is a diagram showing an example of the heatstroke prevention checklist for the embodiment shown in Figures 1 to 13.

[0103] The heatstroke prevention checklist is displayed and printed on administrator terminal 2. The upper section of the heatstroke prevention checklist is a worker self-check called "Morning Meeting Check," which is divided into "Medical History, etc.," "Alcohol Consumption, etc.," and "Self-Awareness." The symbols in the upper right of the diagram are used for these check items. For example, in check No. 1, it is written as "Are you 65 years of age or older (Under 65: ○ 65 years or older: ×)." Also, for example, in check No. 7, it is written as "Did you drink alcohol yesterday (No: ○ Yes: ×)." Furthermore, for example, in check No. 11, it is written as "Am I aware of having a hangover (No: ○ Yes: ×)." The middle to lower section of the heatstroke prevention checklist is a worker self-check called "Foreman Questions and Confirmations During Work and Rest," which is divided into work hours such as "9am," "10am," ... "5pm." The symbols in the upper right of the diagram are also used for these check items. For example, under "10 o'clock hour," the WBGT value (°C) at the work site, a check of physical condition, and whether or not a break of 10 minutes or more was taken are recorded. In this way, this service automatically generates a heatstroke prevention checklist based on various information stored on server 1, and it can be displayed and output as a PDF on administrator terminal 2.

[0104] Next, the flow of devices and information will be explained with reference to Figure 15. Figure 15 is a diagram showing the overall flow of devices and information in this embodiment shown in Figures 1 to 14.

[0105] The overall system configuration shown in Figure 15 consists of a cloud server at the top, various devices for the work sites (work locations in Figure 15) located in the middle and lower sections, and the headquarters / administrator's equipment located on the right. Figure 15 shows multiple work sites (for example, work location A, work location B, and work location C). Each work site is equipped with an administrator terminal (foreman's smartphone), multiple worker mobile terminals (smartwatches), a WBGT measuring device, and a gateway. Cameras are also installed, although they are not shown in the diagram (see server 1, administrator terminal 2, worker mobile terminal 3, WBGT measuring device 4, gateway 5, and camera 6 in Figures 1 and 5).

[0106] The worker's mobile terminal and the WBGT measuring device are connected to the gateway via Bluetooth® communication. Gateway 5 converts the information received via Bluetooth® communication to mobile communication (4G or 5G) or Wi-Fi communication and transmits it to the cloud server via the internet, etc. The administrator terminal and camera communicate directly with the cloud server via mobile communication or Wi-Fi communication. The cloud server provides a heatstroke prevention support service as a cloud service. The cloud server collects various information transmitted from each work site, performs real-time analysis and AI analysis, calculates corrected WBGT standard values, heatstroke risk values, various alarms, etc., and distributes them to the administrator terminal and the worker's mobile terminal.

[0107] At headquarters and among administrators, administrator terminals (PCs or smartphones) are installed, allowing for remote monitoring of the situation at each work site. The heatstroke prevention support service visualizes the actual situation at each work site, enabling safety and health managers to optimize their efforts. Furthermore, it allows for information sharing with industrial physicians. Due to the equipment used and the flow of information, the heatstroke prevention support service does not require the installation of large-scale equipment for implementation, and can be implemented without significant burden on foremen and workers. In addition, it is possible to track the location information of each worker, as it is possible to see which gateway they are working near.

[0108] Next, we will describe examples of equipment used with reference to Figure 16. Figure 16 is a diagram showing examples of equipment used in the embodiment of Figures 1 to 15.

[0109] Figure 16 shows the specifications of the equipment used in a table format. For three types of equipment—WBGT measuring device, worker mobile terminal (smartwatch), and gateway—the following items are listed: appearance, model number, function, usage location, Bluetooth® LE compatibility, external communication interface, power supply, operating temperature, and dimensions.

[0110] The WBGT measuring device has the function of measuring black globe temperature, wet bulb temperature, and dry bulb temperature and outputting the WBGT value. It is used at the work site. The worker's portable terminal has the function of outputting heart rate, blood oxygen saturation, and activity level (steps). It is used by workers. It is also effective to use a smartwatch that outputs stress index, wrist surface temperature, core body temperature, stress assessment, and blood pressure. The gateway has the function of converting between Bluetooth® communication and mobile communication. The gateway should be one that can collect information from multiple devices, send alarms, and detect the presence of devices. In this way, equipment suitable for the system of this embodiment can be selected according to the specifications of the equipment used as shown in Figure 16.

[0111] Next, with reference to Figure 17, the types and content of alarms associated with exceeding the corrected WBGT reference value will be explained. Figure 17 is a diagram showing the types and content of alarms associated with exceeding the corrected WBGT reference value in the embodiment shown in Figures 1 to 16.

[0112] As shown in Figure 17, if the temperature exceeds the corrected WBGT standard value by approximately 1°C, and the period without a break continues for 15 minutes or more, and the count time is within 75 minutes, a break alarm will be issued with the message "Take a break for 15 minutes or more." Similarly, if the temperature exceeds the standard value by approximately 2°C, an alarm will be issued for a break of 30 minutes or more, and if it exceeds the standard value by approximately 3°C, an alarm will be issued for a break of 45 minutes or more. If the temperature exceeds the corrected WBGT standard value by 4°C or more, it is desirable to stop work, and a yellow alarm will be issued with the message "Stop work." In this case, no break alarm will be issued. Note that the period without a break here refers to the period during which the step count equivalent value is 15 steps or less in 10 minutes. These standard values ​​are calculated based on the permissible limits of the American Conference of Governmental Industrial Hygienists (ACGIH). In this way, this service can encourage breaks at the appropriate time and help prevent heatstroke by using the types and content of alarms that accompany exceeding the corrected WBGT standard value as shown in Figure 17.

[0113] Next, the thresholds for information types and the types and content of alarms will be explained with reference to Figure 18. Figure 18 is a diagram showing the thresholds for information types and the types and content of alarms in the embodiment shown in Figures 1 to 17.

[0114] Figure 18 shows, in tabular format, the following items: type of information, threshold for alarm generation, type of alarm, content of the alarm, and remarks. The types of information are classified into vital information (heart rate, blood oxygen saturation) and information gathered during patrols (physical condition, rest / hydration / salt intake). Based on the thresholds, alarm types, and content for each type of information shown in Figure 18, appropriate alarms can be issued based on the vital information acquired from the worker's mobile terminal 3 and the information gathered during patrols acquired from the administrator's terminal 2. This allows the service to implement heatstroke prevention measures tailored to the physical condition of the workers.

[0115] Next, with reference to Figure 19, we will explain the WBGT reference values ​​according to the intensity of physical work. Figure 19 is a diagram showing the WBGT reference values ​​according to the intensity of physical work for the embodiments shown in Figures 1 to 18.

[0116] Figure 19 shows, in a table format, each item: classification, example of physical work intensity (metabolic rate level), and WBGT reference value (WBGT reference value for heat-acclimatized individuals, WBGT reference value for heat-unacclimatized individuals). The classification is divided into five stages: 0 (rest), 1 (low metabolic rate), 2 (moderate metabolic rate), 3 (high metabolic rate), and 4 (extremely high metabolic rate). The WBGT reference values ​​based on work intensity shown in Figure 19 allow for setting an appropriate WBGT reference value according to the physical work intensity (metabolic rate level) of the work. In addition, different reference values ​​are set for heat-acclimatized and heat-unacclimatized individuals, allowing for the application of a reference value according to the heat acclimatization status of the worker (SW).

[0117] Next, with reference to Figure 20, the corrective values ​​for clothing that should be added to the WBGT standard value based on the combination of clothing will be explained. Figure 20 is a diagram showing the corrective values ​​for clothing that should be added to the WBGT standard value based on the combination of clothing according to the embodiment shown in Figures 1 to 19.

[0118] As shown in Figure 20, the WBGT standard value can be corrected according to the type of clothing worn by the worker (SW). This allows for the calculation of a more accurate heatstroke risk value that takes into account the increased heat stress caused by clothing.

[0119] Next, with reference to Figure 21, the corrected values ​​(WBGT corrected values) based on physical condition and medical history at the time of commuting will be explained. Figure 21 is a diagram showing the WBGT corrected values ​​based on physical condition and medical history at the time of commuting for the embodiments shown in Figures 1 to 20.

[0120] Figure 21 shows the adjustment items and adjustment values ​​in a table format. The adjustment items are classified into two categories: physical condition at the time of arrival at work (self-awareness, alcohol consumption, etc.) and medical history. Regarding physical condition at the time of arrival at work, for self-awareness, the adjustment value is 0 if there is no self-awareness, 1 if there is a hangover, 0.8 if there is an upset stomach, 1 if there is a slight cold or fever, and 1 if there is poor physical condition. For alcohol consumption, the adjustment value is 0 if there was no alcohol yesterday, 0.2 if there was alcohol yesterday, 0.7 if there was too much alcohol, 0.5 if the sleep duration was less than 5 hours, and 0.5 if no fluids or salt were consumed at breakfast. Regarding medical history, the adjustment values ​​are as follows: 0.5 if the individual is 65 years of age or older, 0.7 if they have a history of heart disease, 0.5 if they have had heatstroke in the past, 1 if they experience heatstroke every year, 0.5 if they feel unwell during the summer, 0.7 if they have high blood pressure, and 0.5 if they are obese or not physically active.

[0121] As shown in Figure 21, the WBGT standard value can be adjusted according to the worker's physical condition and medical history at the time of arrival at work. These adjustment values ​​are determined based on the advice of an industrial physician, etc., and by combining them with the WBGT standard value based on work intensity in Figure 19 and the WBGT adjustment value based on clothing in Figure 20, an individual adjusted WBGT standard value (second standard value) can be calculated for each worker. Then, the heatstroke prevention risk value (third standard value) can be calculated as the difference between this adjusted WBGT standard value and the WBGT value (first standard value).

[0122] Figure 22 shows another example of the Job IN screen. In the Job IN screen of Figure 22, inputs for the worker's work and physical condition include name, watch status, work status, self-awareness / not awareness, alcohol consumption, medical history, work intensity, clothing, etc., mitigation measures, heat acclimatization, WBGT correction value, date of birth, and mobile phone number. In the work status field, inputs include attendance, absence, attendance without special consideration, absence with special consideration. In the self-awareness / not awareness field, inputs include no awareness, hangover, lack of sleep, upset stomach, feeling under the weather / feverish, feeling unwell, etc. In the alcohol consumption / not awareness field, inputs include no alcohol yesterday, drank yesterday, drank too much, less than 5 hours of sleep, no breakfast / water / salt intake, etc. In the medical history field, inputs include being over 65 years old, history of heart disease, past history of heatstroke, history of heatstroke every year, feeling unwell in summer, high blood pressure, obesity or lack of exercise, etc. In addition, the work intensity column is used to input rest, low metabolic rate, moderate metabolic rate, high metabolic rate, and extremely high metabolic rate. In the clothing column, inputs include work clothes, overalls, single-layer polyolefin nonwoven fabric overalls, single-layer SMS nonwoven fabric overalls, wearing two layers of woven clothing, wearing a long-sleeved, long-length, breathable apron over overalls, single-layer breathable overalls without a hood, single-layer breathable overalls with a hood, and breathable overalls without a hood worn over clothing. Note that medical history, work intensity, clothing, mitigation measures, and heat acclimatization are often the same as the previous day, so it is preferable to set the default settings of the checklist to be the same as the previous day. This makes the daily checks upon arrival at work mainly about self-awareness and alcohol consumption, and only requires attention to changes in other areas, thus allowing for the data collection of the worker's SW status with minimal effort, and enabling adjustments to work arrangements based on the obtained WBGT correction values.

[0123] Figure 23 shows another example of the "Work in Progress" screen. When work begins, the foreman's (administrator F) administrator terminal 2 displays a "Work in Progress" screen similar to Figure 23, not just Figure 10.

[0124] Figure 24 shows an example of setting correction values. The correction values ​​in this embodiment are divided as shown in Figure 24. That is, correction values ​​based on the Ministry of Health, Labour and Welfare guidelines and correction values ​​based on the company's own standards. In Figure 19 mentioned above, since there is no proportional relationship between heat acclimatization and work intensity, the WBGT standard value is calculated using a quadratic equation or matrix, and then plus or minus the correction values ​​in Figures 20 and 24. It is preferable to analyze the cause, focusing on the person who triggered the alarm, and revise the values ​​to optimize them. The standards for correction values ​​can be organized into public standards (first standard stipulated by the national and local governments) and company-specific standards (second standard). Public standards are described in the Ministry of Health, Labour and Welfare's "Basic Guidelines for Preventing Heatstroke in the Workplace" (see Figures 19 and 20). The WBGT standard value changes depending on the work intensity and heat acclimatization. If the WBGT temperature of the work environment exceeds this standard value, it is judged that the risk of heatstroke has increased, and the risk of heatstroke is expressed as a plus or minus. The WBGT correction value in Figure 20 adjusts the baseline value according to the type of clothing worn. Since a higher risk requires a larger correction value, the correction value is added to the baseline value in Figure 19 to determine the corrected baseline value. This value is then compared to the WBGT temperature of the work environment to display the risk of heatstroke. In actual work environments, there are many factors that increase the risk of heatstroke besides the clothing shown in Figure 20, as well as measures to reduce the risk. Therefore, by setting correction values ​​for each of these factors and measures (see Figure 24), it is possible to calculate a WBGT correction value that reflects a wide range of factors and measures.

[0125] Figure 25 shows an example of alarm types and content. The alarm types and content are not limited to those shown in Figure 18; they may include messages, alarm conditions, background color change items, etc., as shown in Figure 25.

[0126] Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiments described above, and any modifications, improvements, etc. that can achieve the objectives of the present invention are considered to be included in the present invention.

[0127] Up to this point, we have explained the heatstroke prevention support service for preventing heatstroke. This is a measure for the hot season from June to September. From October to May of the following year, measures to prevent physical abnormalities are desired. In this case, rather than risk management based on WBGT values, management based on physical abnormality risk values ​​based on activity levels is effective. Activity levels here refer to cases where the time without rest within a certain counting period is below a threshold, and where the activity time (for example, 100 steps or more per 10 minutes) is below a threshold. The alarms include a rest alarm for time without rest and an activity promotion alarm that encourages physical activity because the activity time is short. Other alarms are the same as those for heatstroke prevention.

[0128] In the above embodiment, the logic for calculating risk from the WBGT value and the corrected WBGT reference value was (basically the difference). However, it is also possible to create a correction value that changes from fluctuating vital values ​​(heart rate and blood oxygen, etc.) and display the risk after correcting with this correction value. In addition, in the above embodiment, the foreman patrols around the workers (SW) regardless of order or priority and checks on them by talking to them. However, it is possible to talk to people at high risk first by referring to accumulated daily information, for example (the order of talking to them is displayed, etc.). Furthermore, by using AI analysis, the correlation between input information and output information can be analyzed and the correction value can be optimized. For example, if the input information is activity level and heatstroke risk, and the output information is heart rate and blood oxygen, the correlation between these and the check items at the time of work entry can be used to optimize the correction value.

[0129] In the above-described embodiment, the focus is on managing heatstroke risk, but during the off-season for heatstroke, health management can be promoted focusing on blood oxygen concentration. Since the information from this service in the above-described embodiment is continuous information during work, it can be combined with, for example, temporary medical information managed for employees within the company to improve the accuracy of internal medical information. A more accurate WBGT correction value can be set from the internal medical information to manage heatstroke risk values. The information from this service in the above-described embodiment can be treated as big data, and trends in job-specific risks, work-site-specific risks, and work-content-specific risks can be digitized and treated as preventive data.

[0130] Furthermore, the system configuration shown in Figure 2 and the hardware configuration of Server 1 shown in Figure 3 are merely illustrative examples for achieving the objectives of the present invention and are not particularly limited.

[0131] Furthermore, the functional block diagram shown in Figure 4 is merely illustrative and not particularly limiting. In other words, it is sufficient that the information processing system in Figure 2 has the functionality to execute the various processes described above as a whole, and the functional blocks and databases used to realize this functionality are not particularly limited to the example in Figure 4.

[0132] Furthermore, the location of the functional blocks and database is not limited to Figure 4 and can be any location. For example, at least a portion of the functional blocks and database located on the server 1 side may be provided on the administrator terminal 2 side, the worker's mobile terminal 3 side, the WBGT measuring device 4 side, the gateway 5 side, the camera 6 side, or other information processing devices not shown.

[0133] Furthermore, the series of processes described above can be executed by hardware or by software. Also, a single functional block may consist of hardware alone, software alone, or a combination of both.

[0134] When a series of processes are executed by software, the programs that make up that software are installed on a computer or other device from a network or storage medium. The computer may be a computer built into dedicated hardware. Alternatively, the computer may be a computer capable of performing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0135] Such recording media containing programs may consist not only of removable media (not shown) distributed separately from the main unit of the device to provide the program to the user, but also of recording media provided to the user in a state where they are pre-installed in the main unit of the device.

[0136] In this specification, the step of describing a program to be recorded on a recording medium includes not only processes that are performed chronologically in that order, but also processes that are not necessarily performed chronologically, but are executed in parallel or individually.

[0137] In summary, the information processing device to which the present invention applies only needs to have the following configuration, and can take various forms. That is, the information processing device to which the present invention applies (for example, Server 1 in Figures 1 to 4) includes a first reference value acquisition means (for example, WBGT value acquisition unit 51 in Figure 4) that acquires a first reference value (for example, the WBGT value shown above) at a work site (for example, work site A and work site B in Figure 1) where a worker (for example, field worker SW in Figure 1) is present, using a standard for the work environment (for example, the WBGT value in Figure 1) defined by a predetermined public standard setting organization (for example, Japanese Industrial Standards), and A worker site information acquisition means (for example, the worker site information acquisition unit 52 in Figure 4) acquires information as worker site information, which is a combination of one or more of the physical conditions of the worker present at the site (for example, physical condition, medical history, and heat acclimatization status at the time of arrival at work as shown in Figures 1, 7, and 8, vital information as shown in Figures 1, 10, and 11, physical condition information during rounds as shown in Figures 10 and 11, and rest / hydration / salt intake information as shown in Figures 10 and 11) and one or more of the work conditions (for example, work intensity as shown in Figures 1, 7, and 8, clothing, etc.), and a second standard value calculation means (for example, the individual worker standard value calculation unit 54 in Figure 4) calculates a second standard value (for example, the corrected WBGT standard value described above) for the worker present at the site based on the worker site information, using a standard indicating the degree of tolerance of a person to the work environment as the second standard, It is sufficient to have a third standard value calculation means (for example, the heatstroke risk value calculation unit 55 in Figure 4) that calculates the third standard value (heatstroke risk value of worker SW) for the workers present at the site based on the difference between the first standard value and the second standard value, with the third standard value being a standard that indicates the degree of risk of heatstroke in people.

[0138] In this way, it becomes possible to reduce the burden on administrators regarding heatstroke prevention and to take timely action.

[0139] Furthermore, the worker site information acquisition means can acquire vital information (for example, heart rate, blood oxygen saturation, and activity level shown in Figures 1, 10, 11, and 18) obtained from a wearable terminal worn by the worker (for example, worker mobile terminal 3 in Figures 1, 2, and 5) as at least part of the worker site information.

[0140] This makes it possible to calculate a second baseline value that reflects the physical condition of the workers in real time.

[0141] Furthermore, the worker site information acquisition means can acquire, as at least part of the worker site information, interview information obtained as a result of interviewing the worker about at least some of the above-mentioned physical conditions and work conditions of the worker (for example, physical condition at the time of arrival at work, medical history, work intensity, clothing, heat acclimatization as shown in Figures 1, 7, and 8, and physical condition information during patrols, and information on rest and fluid / salt replenishment as shown in Figures 10 and 11).

[0142] This makes it possible to calculate a second baseline value that reflects the individual condition of each worker.

[0143] Furthermore, the second reference value calculation means may further include a correction value calculation means (for example, the correction WBGT reference value in Figure 11) which calculates the second reference value (for example, the corrected WBGT reference value in Figure 11) by performing a predetermined calculation on the first reference value (for example, the WBGT value in Figures 11 and 19) using correction values ​​based on the worker's on-site information (for example, the WBGT correction value based on work intensity in Figures 19, 20, and 21, the WBGT correction value based on clothing, and the WBGT correction value based on the worker's physical condition and medical history at the time of arrival at work), and a correction value calculation means (for example, the correction value calculation unit 53 and AI analysis unit 59 in Figure 4) which calculates the correction value by AI analysis of the interview information and the vital information.

[0144] This allows for the calculation of a more accurate second reference value, thereby improving the accuracy of heatstroke prevention.

[0145] Furthermore, the system can be further equipped with a question management means (for example, the question management unit 56 in Figure 4) that can present one or more questions related to heatstroke prevention (for example, the questions in the quiz in Figure 9) to the terminal of an administrator (for example, administrator F (foreman) in Figure 1) (for example, administrator terminal 2 in Figures 1, 2, and 5) and manage the administrator's answers.

[0146] This will make it possible to raise the knowledge and awareness of managers regarding heatstroke prevention.

[0147] Furthermore, the problem management means can weight each problem based on the interview information (for example, interview information at the time of arrival at work, information on rest and fluid / salt replenishment during patrols, the value from the WBGT measuring device 4, and the value of steps, which is activity, from the worker's mobile terminal 3) and the vital information (for example, heart rate, blood oxygen saturation, step count, which is activity level, and physical condition information during patrols from the worker's mobile terminal 3), and can prioritize presenting problems with a high risk.

[0148] This allows for the effective acquisition of practical knowledge by prioritizing questions that are relevant to the risk situation on-site.

[0149] Furthermore, the system may be further equipped with worker site image acquisition means for acquiring images that include the workers present at the site as subjects, obtained from images captured by a camera installed at the site (for example, camera 6 in Figures 1, 2, and 5), as worker site images.

[0150] This makes it possible to visually understand the situation on site.

[0151] Furthermore, the system may be further equipped with an alert output means (for example, the alert output unit 58 in Figure 4) that outputs an alert (for example, the rest alarm, yellow alarm, and red alarm shown in Figures 6, 17, and 18) when the third reference value (the heatstroke risk value for worker SW) exceeds a predetermined threshold.

[0152] This makes it possible to alert managers and workers in a timely manner.

[0153] Furthermore, the alert output means can transmit the worker site image (for example, an image captured by the camera 6 in Figures 1, 2, and 4) to the administrator's terminal as an alert or together with the alert.

[0154] This allows for an instant assessment of the situation on-site and enables appropriate responses.
