The heat stroke risk management system according to the present embodiment grasps in real time the biological information at the time of work of the worker who is the target of the determination of the risk of developing heat stroke, and changes from the biological information obtained when the worker is at rest. Based on this, the worker determines and manages the risk of developing heat stroke. In particular, inform workers who work in workplaces that require physical labor under hot summer heat, such as the construction industry and transportation industry, when the risk of developing heat stroke exceeds a certain level. Can be warned to take a rest.

  FIG. 1 is an image diagram for explaining a schematic configuration of a heat stroke risk management system according to the present embodiment.

  FIG. 2 is a block diagram showing a configuration example of each part of the heat stroke risk management system according to the present embodiment.

  As shown in FIG. 1, an operator 10 working on a construction site as an example wears a data chip 11, which is a biological information acquisition unit that acquires biological information such as body temperature, heart rate, and sweating amount, on the chest, It has a smartphone 12 as a portable terminal that functions as a biological information transmission unit that transmits biological information obtained by the data chip 11 to the outside.

  The data chip 11 and the smartphone 12 are always connected by short-distance communication such as Bluetooth (registered trademark), and the biological information of the worker 10 acquired by the data chip 11 is sent to the smartphone 12 at any time. Yes.

  The smartphone 12 is always connected to the Internet 20 as a network environment by using a data reception unit 15 and a data transmission unit 16 included in the smartphone 12 using an information carrier of a wireless LAN or a mobile phone. Then, the smartphone 12 transmits the biological information of the worker 10 to the cloud server 21 that is a server provided with a heat stroke risk determination unit installed on the Internet 20.

  The cloud server 21 includes a data reception unit 23 and a data transmission unit 26 therein, can exchange information via the Internet 20, and includes a heat stroke risk determination unit 22, and includes a plurality of operations. The biometric information of each worker is received, the heat stroke onset risk for each worker is determined, and if the risk of developing heat stroke is increased, warning information is generated to warn the worker of that fact. In addition, the cloud server 21 includes a data recording unit 24, and can record biometric information of individual workers, creation history of warning information, and the like in time series.

  In addition, the cloud server 21 obtains weather information (25) from an information site that provides weather information via the Internet 20, and presents the current temperature, humidity, and amount of sunlight in the area where the worker 10 is working. It is possible to acquire weather forecasts that anticipate the weather conditions at the time and changes in the next few hours.

  The cloud server 21 is connected via the Internet 20 to a personal computer 31 as an information terminal used by a supervisor 30 who supervises the work of the worker 10 to be determined on site. For this reason, the supervisor 30 at the work site of the worker 10 determines whether or not the biometric information and warning information of the worker 10 transmitted from the cloud server 21 at any time is generated by the data receiving unit 33 of the personal computer 31. I can grasp it.

  The heat stroke risk determination unit 22 of the cloud server 21 can determine the risk that the worker 10 will develop heat stroke based on a change in biological information. Specifically, the heat stroke risk determination unit 22 generates a threshold value for determining whether or not the risk of developing heat stroke is increased based on resting data that is biological information acquired when the worker 10 is at rest. The risk of developing heat stroke of the worker 10 is determined by comparing the threshold value with the working data that is biological information during the work.

  In addition, the cloud server 21 includes the past history information of the determination target worker 10 recorded in the data recording unit 24, the weather information of the work area acquired by the weather information acquisition unit 25, and the determination target worker. Based on environmental information such as changes in biological information of other workers, the judgment result of the heat stroke occurrence risk of the worker 10 can be corrected to make it more realistic.

  The personal computer 31 of the supervisor 30 includes an information management unit 32 that manages whether biometric information and warning information about a worker belonging to a work site supervised by the supervisor 30 including the worker 10 is generated. ing. Based on the information transmitted from the cloud server 21, the information management unit 32 displays a list on the monitor whether or not biometric information or warning information of each worker has been generated. Enables centralized situation management for all workers working on site.

  The personal computer 31 of the supervisor 30 confirms whether or not the worker 10 has taken measures against heat stroke by receiving the biological information of the worker 10 after notification of the warning information and the receipt confirmation from the worker 10. When the worker 10 is not taking measures, the worker 10 can be alerted by repeatedly transmitting warning information.

  Further, the supervisor 30 can take measures against heat stroke at the work site to be executed and supervised as appropriate when means for improving the work environment at the work site can be taken.

  In the above description, the warning information for notifying the worker 10 that the risk of developing heat stroke is high has been described by the heat stroke risk determination unit 22 of the cloud server 21. Can be generated by the information management unit 32 installed in the personal computer 31 of the supervisor 30. Moreover, it can also set so that warning information may be produced | generated by both the heat stroke risk determination part 22 and the information management part 32. FIG. Prior to the determination result in the heat stroke risk determination unit 22 from the personal computer 31 of the supervisor 30 who actually supervises the work site, warning information is generated and transmitted to the worker 10, so that the actual situation of the work site can be obtained. Accordingly, the risk of developing heat stroke may be further reduced.

  Warning information generated by the heat stroke risk determination unit 22 of the cloud server 21 or the personal computer 31 of the supervisor 30 is transmitted from the data transmission unit 34 of the personal computer 31 of the supervisor 30 to a local network such as a wireless LAN or a mobile phone. It transmits to the smart phone 12 with which the operator 10 is equipped via the network containing an information carrier. The warning notification unit 14 of the smartphone 12 that has received the warning information uses a variety of information transmission means such as voice, screen display, lighting or blinking of the lamp, vibration, etc. Notify that it is increasing. The worker 10 who has confirmed the warning information reports that the warning information has been received through the touch panel or the operation button of the smartphone 12 and performs measures such as interrupting the work and taking a rest.

  The smartphone 12 of the worker 10 transmits the fact that the worker 10 has confirmed the warning information and interrupted the work to the personal computer 31 of the supervisor 30, and the supervisor 30 takes measures against the heat stroke. Can be confirmed.

  The cloud server 21 is also connected to the management computer 41 in the company or office 40 to which the worker 10 belongs through the Internet 20, and the biological information of the worker 10 transmitted to the personal computer 31 of the supervisor 30 The cloud server 21 transmits various types of information used to determine the risk of developing heat stroke to the management computer 41 of the office 40 in real time. Since the management computer 41 of the business office 40 has its own data receiving unit 42 and data transmitting unit 43, it is also connected to the information terminal 31 of the supervisor 30 via the Internet. 10 can confirm information such as whether the warning information has been correctly transmitted or whether the worker 10 has taken measures against heat stroke, and can give a predetermined instruction as necessary. By doing in this way, also in the business office 40 to which the worker 10 belongs, the situation of the worker 10 and the response at the work site can be confirmed, and the avoidance of the heat stroke risk of the worker 10 is backed up. be able to.

  Although not explicitly shown in FIG. 1, the cloud server 21, the personal computer 31 of the supervisor 30, and the management computer 40 of the business office 40 are connected via the Internet 20. The cloud server 21 can be accessed from the side, the data processing content in the cloud server 21 is controlled, the determination program in the heat stroke risk determination unit 22 is updated, and the risk management of heat stroke from the cloud server 21 Necessary information can be taken out as appropriate.

  In the above description, a smartphone is illustrated as a portable terminal that an operator is equipped with, but the worker's portable terminal is not limited to a smartphone, and is specialized in a mobile phone, a tablet device, and further a heat stroke risk management system. Various devices capable of transmitting and receiving information can be used.

  In addition to the personal computers exemplified by the supervisor, especially the desktop personal computer illustrated in FIG. 1, information transmission / reception and data display via a network such as notebook personal computers, tablet personal computers, and small server devices are also possible. Various information devices capable of recording data can be employed.

  Furthermore, in the above description, the mode in which warning information is transmitted from the supervisor's information device to the worker's mobile terminal has been described. However, when the warning information is generated by the heat stroke risk determination unit of the cloud server, the cloud server The system can also be configured to send warning information directly to the worker's mobile terminal.

  Next, the operation | movement which manages the heat stroke onset risk of an operator in the heat stroke risk management system concerning this embodiment is demonstrated. In addition, in description of operation | movement, the code | symbol attached | subjected to the block which shows the component of the heat stroke risk management system concerning this embodiment shown in FIG. 2 suitably is quoted.

  FIG. 3 is a flowchart for explaining the operation of the mobile terminal equipped by the worker in the heat stroke risk management system according to the present embodiment.

  In addition, in the heat stroke risk management system according to the present embodiment as described above, the portable terminal 12 (smart phone) that the worker 10 is equipped with is the biological information acquisition unit 11 (data chip) that the worker 10 is wearing on the chest. ) Includes a biological information transmission unit 13 that transmits the biological information acquired to the cloud server 21 and a warning notification unit 14 that transmits warning information to the worker 10 when the risk of developing heat stroke increases. It fulfills two functions.

  As shown in FIG. 3, the mobile terminal 12 is turned on and the operation is started by the operator 10 operating at the time of wearing or by a timer set at a predetermined time. When a smartphone owned by the worker 10 is caused to function as a mobile terminal by installing a predetermined application, the power supply is normally always on.

  The portable terminal 12 acquires resting data that is biological information such as body temperature, heart rate, and sweating amount of the worker 10 at rest from the biological information acquisition unit 11 (step S101). The resting data is obtained when the worker 10 is engaged in the work, such as when the worker changes into work clothes in the changing room and wears the portable terminal 12 or is attending a morning meeting at a work site. It can be acquired in a state where a large physical load is not applied. Moreover, resting data can be estimated from the biological information of the worker 10 during normal work. Furthermore, in the case of the worker 10 whose risk of developing heat stroke has been managed by the heat stroke risk management system shown in the present embodiment, resting data recorded as a past history can be used.

  The portable terminal 12 transmits the resting data transmitted from the biometric information acquisition unit 11 to the cloud server 21 on the Internet 20 via a wireless LAN or the like (step S102).

  Subsequently, the portable terminal 12 acquires the biological information at the time of work of the worker 10 transmitted from the biological information acquisition unit 11 as work time data (step S103). Moreover, the portable terminal 12 transmits the work time data of the worker 10 to the cloud server 21 (step S104). Actually, the biological information acquisition unit 11 automatically acquires the biological information of the worker 10 at intervals of several seconds to several minutes and sequentially transmits the acquired data to the mobile terminal 12. The biometric information received at 12 is not distinguished from “resting data” and “working data”. Whether the biometric information acquired by the mobile terminal 12 is acquired when the worker 10 is resting. Whether it was acquired when engaged in work or not is distinguished in consideration of biometric information itself and data acquisition information such as acquisition time.

  In addition, in order to reliably acquire resting data serving as a reference for determining the risk of developing heat stroke, the operator operates the mobile terminal 12 before starting work, and the biometric information acquired at that time is resting. It can be clarified that it is time data.

  Thus, the mobile terminal 12 transmits the biological information of the worker 10 acquired by the biological information acquisition unit 11 to the cloud server 21 as needed. Thereby, the cloud server 21 can always determine the risk of developing heat stroke by grasping the biological information of the worker 10.

  Note that the heat stroke risk management system of the present invention needs to specify and record / manage which worker's biological information is the received biological information in order to manage the biological information of a plurality of workers. . For this reason, you may provide the mechanism which manages biometric information based on ID provided to the worker individual. For example, an ID card equipped with a QR code (registered trademark) or an IC chip may be issued for each worker, and the portable terminal 12 may read the ID card before starting the work. By registering the read ID information in the cloud server 21 or adding it to the biometric information and transmitting it, the mobile terminal 12 can identify and manage who the biometric information sent is on the cloud server 21 side. This method is effective when the worker does not always use the same portable terminal every day, such as lending a portable terminal to the worker. This is especially effective when there are frequent changes of people, such as at construction sites.

  Although the portable terminal 12 includes the warning notification unit 14, in a state where warning information is not received (in the case of “No” in Step S105), the work end of the worker 10 is not detected (“ In the case of “No”), the function of the biometric information transmitting unit 13 that transmits the biometric information acquired by the biometric information acquiring unit 11 to the cloud server 21 is executed by repeating the operation of each step described above.

  On the other hand, it is detected that the worker 10 has finished the work by the operation of the worker 10 himself / herself or from various information such as the current position information and biological information of the worker 10 and the elapse of the work end time that has been grasped in advance. If it is possible (if “Yes” in step S106), the portable terminal 12 stops the function of transferring the biological information and the function as the warning notification unit. In addition, when the portable terminal 12 is the smart phone etc. which the worker 10 owns, the function as a smart phone will be continued.

  As described with reference to FIGS. 1 and 2, in the heat stroke risk management system according to the present embodiment, when it is determined from the biological information of the worker 10 that the worker 10 has an increased risk of developing heat stroke. , Warning information is issued, and the mobile terminal 12 receives this via the network.

  When the mobile terminal 12 receives the warning information (in the case of “Yes” in step S105), the mobile terminal 12 performs a function as a warning notification unit, such as voice, screen display, lamp lighting / flashing, Using means such as vibration, the worker 10 is notified that the risk of developing heat stroke is increasing (step S107).

  When the worker 10 confirms the warning information, the operator 10 operates the input means such as the touch panel and various operation buttons of the portable terminal 12 to intentionally display the fact. When an input indicating that the warning information has been confirmed is received from the worker 10 (in the case of “Yes” in step S108), the operation of the mobile terminal 12 as the warning notification unit is ended. At this time, since the worker 10 moves to a rest room and takes a rest in order to avoid the risk of developing heat stroke, the function as the biological information transmitting unit of the portable terminal 12 is also terminated. When the operator 10 recovers the physical condition by interrupting the work and taking a rest, and again engaging in the work, the operation shown in the flowchart of FIG. 3 is repeated from the start.

  In addition, although illustration is abbreviate | omitted, even after the operator 10 interrupted work, the portable terminal 12 transmits the biometric information of the operator 10 to the cloud server 21, and the operator 10 has taken an appropriate rest. Monitoring can be enabled.

  Moreover, although illustration is abbreviate | omitted, when the operator 10 takes measures to avoid the risk of developing heat stroke, the mobile terminal 12 is set to notify the information device 31 of the supervisor 30 directly. Can do. In this way, the supervisor 30 can immediately confirm that the worker 10 has taken correct measures to avoid the onset of heat stroke.

  On the other hand, if the operator 10 has not performed an operation to confirm the warning information (“No” in step S108), the mobile terminal 12 notifies the information device 31 of the supervisor 30 to that effect. (Step S109). Moreover, the portable terminal 12 alert | reports warning information with respect to the operator 10 anew (step S107).

  By doing in this way, supervisor 30 can confirm serious situations, such as a case where worker 10 has already developed heat stroke and cannot perform predetermined check operation at an early stage. Although illustration is omitted, the mobile terminal 12 is configured so as to transmit the fact to the cloud server 21 when the confirmation operation for the warning information by the worker 10 is not performed. It can be transmitted from the server 21 to not only the supervisor 30 but also the monitoring staff of the office 40 of the operator 10 via the Internet 20, and communication between the portable terminal 12 and the information device 31 of the supervisor 30. An unexpected situation where the operator 10 has not confirmed the warning information even if the emergency situation is such that the operator has been disconnected or the supervisor 30 has been faced with an unexpected trouble and cannot respond immediately. Can be understood.

  Next, the operation of determining the risk of developing heat stroke in the heat stroke risk management system according to the present embodiment will be described.

  FIG. 4 is a flowchart for explaining the operation of determining the risk of developing heat stroke, particularly in the cloud server and the supervisor's information device.

  Although the cloud server 21 is always in an operating state on the Internet environment, the operation from the start to the end of the operation as the heat stroke risk management system according to the present embodiment will be described.

  As illustrated in FIG. 4, the cloud server 21 acquires resting data that is biometric information of the worker 10 at rest transmitted from the mobile terminal 12 that the worker 10 is equipped with (step S201). The cloud server 21 records the received resting data in the data recording unit 24 and transmits it to the information device 31 of the supervisor 30 who supervises the work site and the management computer 41 of the office 40 through the Internet 20 (step S202). ).

  Subsequently, the cloud server 21 receives work-time data, which is biological information at the time of work, from the portable terminal 12 of the worker 10 (step S203), records this in the data recording unit 24, and the information device of the supervisor 30 31 and transmit to the management computer 41 of the office 40 (step S204).

  Since the resting data and the working data of the worker 10 are obtained, the heat stroke risk determination unit 22 of the cloud server 21 determines the heat stroke occurrence risk of the worker 10 based on two pieces of biological information.

  In the heat stroke risk management system according to the present embodiment, the body temperature, heart rate, sweating amount, etc. at the time of work of the same worker are grasped as work time data, and compared with the biological information at rest before the work starts. Then, the fluctuation value is calculated (step S205a). For example, when there is a physical change such as a sudden increase in body temperature, heart rate, or perspiration, the magnitude of the change amount, The risk of developing heat stroke is determined based on the tendency of increase / decrease in the rate of change. In addition, the heat stroke risk determination unit 22 compares the biological information as a general index value recognized as having a high risk of developing heat stroke with the numerical value of the actual biological information of the worker 10. Thus, the risk of developing heat stroke can be determined in a complex manner.

  Further, as described above, since the cloud server 21 records the biometric information obtained in the data recording unit 24 each time the biometric information of the worker 10 is received, the past biometric information of the worker 10 is stored. Owned as history information. When determining the risk of developing heat stroke, the cloud server 21 may call history information that is a change in past biological information of the worker 10 to be determined (step S205b) and correct the determination result of the risk of developing heat stroke. it can. More specifically, the cloud server 21 may consider whether or not the worker 10 is likely to develop heat stroke based on the history information of the determination target worker 10 in the onset risk determination. it can. In addition, by confirming whether the resting data on the day of the judgment is not significantly different from the resting data in the history information, it is possible to estimate the physical condition of the worker 10 at the time of judgment. The determination unit 22 can correct the risk of developing heat stroke in consideration of the physical condition of the operator 10 on the day.

  Furthermore, the cloud server 21 is installed on the Internet 20 by the weather information acquisition unit 25 in the vicinity of the work site where the worker 10 is working from the website of the Japan Meteorological Agency or each weather information provider. Weather information can be obtained as environmental information (step S205c). Because the risk of developing heat stroke changes depending on the weather environment such as whether the work site is at a particularly high temperature and humidity, the wind direction and the wind speed, etc., the weather information is obtained as environmental information and the risk of developing heat stroke It is useful to use it for judgment.

  Moreover, in the heat stroke risk management system of this embodiment, since the cloud server 21 determines the heat stroke risk of the worker 10, biometric information of a large number of workers is obtained at the same time, and the heat stroke risk is determined. The risk of onset can be determined. For this reason, the cloud server 21 obtains other workers' biological information, heat stroke risk determination results, and the like as environmental information (step S205c), and correction in the determination of the heat stroke risk of the worker 10 to be determined. It can be performed. In particular, since the history information of each worker is also stored, it is possible to make a more accurate heat stroke risk assessment in consideration of the tendency of the risk of developing heat stroke at the time of judgment. it can.

  When the cloud server 21 determines that the worker 10 to be determined has a low risk of developing heat stroke and it is not necessary to take measures at this time (in the case of “No” in step S206), the worker 10 performs the work. It is confirmed whether or not the process has been completed (step S207). If the work is completed (“Yes” in step S207), the biological information of the worker 10 of the day is organized and the history data is collected (step S208). End the operation. Although not shown, the history data of the operator 10 can be backed up by transmitting the history data to the information device 31 of the supervisor 30 or the management computer 41 of the business office 40.

  If it is not possible to confirm that the worker 10 has finished the work (in the case of “No” in step S207), the process returns to step S203 to continuously receive the work-time data of the worker 10 and perform the above-described operation. repeat.

  On the other hand, when the cloud server 21 determines in step S206 that it should warn that the worker 10 to be determined has a high risk of developing heat stroke and should take countermeasures (“Yes” in step S206). ), Warning information for notifying the worker that the risk of developing heat stroke is increasing is generated and transmitted to the information device 31 of the supervisor 30 (step S209).

  Hereinafter, the operation steps from step S209 to step S211 are operations performed by the supervisor 30 on the information device 31.

  When receiving the warning information from the cloud server 21, the information device 31 of the supervisor 30 transmits the warning information to the mobile terminal 12 of the worker 10 (step S209).

  The information device 31 of the supervisor 30 determines whether or not an operation indicating that the warning information has been confirmed is performed by the worker 10 (step S210). If the confirmation operation of the worker 10 is permitted (" In the case of “Yes”), the series of operations for determining the risk of developing heat stroke ends.

  In addition, although illustration is abbreviate | omitted, the cloud server 21 notifies the worker 10 that the countermeasure of heat stroke was taken from at least any one of the portable terminal 12 of the worker 10 and the information device 31 of the supervisor 30. In response, the operation of determining the risk of developing heat stroke can be terminated. The cloud server 21 determines that the heat stroke risk should be taken, and then detects that the biological information of the worker 10 has returned to a resting state, thereby determining the risk of developing heat stroke. Can be terminated.

  On the other hand, if the information device 31 of the supervisor 30 has not performed an operation to the effect that the worker 10 has confirmed the alarm information (“No” in step S210), the information device 31 notifies the mobile terminal 12 of the alarm information again. Is instructed to do so (step S211). This operation is repeated until an operation that the worker 10 confirms the alarm information is performed (“Yes” in step S210).

  Although illustration is omitted, when the confirmation operation in which the worker 10 has received the warning information is not performed, the information device 31 of the supervisor 30 displays a large warning on the screen or the like. In addition to notifying the supervisor 30, it can be set to notify the management computer 41 of the office 40 of the situation, and there is a possibility that a situation that cannot be handled only by the work site including the supervisor 30 has occurred. The manager of the business office 40 can be notified.

  In the above description, the cloud server 21 has been described based on an example of creating warning information. However, as described above, a system in which the information device 31 of the supervisor 30 creates warning information can be used. In this case, the operation in step S209 is the operation in the information device 31 of the supervisor 30.

  As described above, in the heat stroke risk management system according to the present embodiment, the risk of developing heat stroke for the worker is determined based on the worker's rest and biological information at the time of work. For this reason, compared to the conventional risk assessment of heat stroke, which is based on the fact that biological information such as body temperature, heart rate, and sweating amount exceeds a predetermined threshold, the constitution of the person to be judged and Taking into account changes in physical condition such as poor health, it is possible to judge the risk of developing heat stroke with higher accuracy, and as a result, it is possible to effectively prevent the worker from developing heat stroke. .

  In FIG. 5, the structural example of the biometric information acquisition part which acquires the worker's biometric information in the heat stroke risk management system concerning this embodiment is shown. Fig.5 (a) has shown the surface of the undershirt with which the biometric information acquisition part was mounted | worn, and FIG.5 (b) has shown the back surface of the undershirt.

  As shown in FIG. 5, the data chip 11 can be disposed on the chest of an undershirt 17 worn by an operator as a biological information acquisition unit in the heat stroke risk management system according to the present embodiment. More specifically, the data chip 11 is connected to the data acquisition / transmission unit 11a and the data acquisition / transmission unit 11a disposed in the chest central portion of the front surface 17a of the undershirt 17, and is connected to the back surface 17b of the undershirt 17. It is comprised from the electrode part 11b arrange | positioned extending in the left-right direction.

  In the heat stroke risk management system of the present embodiment, as a method for acquiring the biological information of the worker 10 with the data chip 11 arranged on the chest, a method of fixing the data chip 11 to the undershirt 17 shown in FIG. It is not limited to. For example, a method in which the data chip 11 is placed in a sheet-like mounting cover with high adhesiveness and this is directly attached to the chest, and work is performed using a stretchable mounting belt that can hold the data chip 11 in close contact with the body. For example, a method of placing on the chest of a person can be employed. However, in the method using the mounting cover or the mounting belt, the discomfort that the operator 10 feels by mounting the data chip 11 cannot be resolved. There is a risk of disengagement from the body surface or displacement of the wearing position.

  On the other hand, according to the method of fixing the data chip 11 to the undershirt 17 worn by the operator 10 as shown in FIG. 5, the operator 10 has a special awareness of wearing the data chip 11. Biological information can be acquired with relaxation. Even if the worker 10 sweats or the body twists during the work, the data chip 11 fixed to the undershirt 17 is not detached from the body surface of the worker 10, and the wearer It is possible to maintain a state in which the position is not substantially changed.

  It should be noted that the movement of the worker's body can be detected in three dimensions by arranging a two-direction or three-direction acceleration sensor on the data chip 11 that acquires the biological information of the worker 10. As a result, for example, when the posture of the worker 10 changes suddenly, for example, when the worker 10 falls, the data chip 11 can detect the movement of the body.

  When the data chip 11 is used as a biometric information acquisition unit that acquires the biometric information of the worker 10, the data chip 11 is disposed at the waist, back, upper arm of the worker in addition to the chest of the worker as described above. The form arrange | positioned to a leg part etc. is employable. Even in these cases, the data chip 11 is fixedly fixed to the body surface of the worker by using a mounting cover or a mounting belt as well as a method of arranging the data chip on the inner surface of the underwear. Can be used.

  Furthermore, in recent years, a wristwatch type data chip, which has been put into practical use as a representative example of a wearable terminal, can be employed as the biological information acquisition unit. In the case of a wristwatch type data chip, for example, there is an advantage that the operator is less likely to feel uncomfortable at the time of wearing, compared with a method of wearing a data chip by winding an elastic mounting belt around the chest. However, in the case of a wristwatch-type data chip, the area of the electrode that contacts the body surface of the operator is reduced, and since it is not always in close contact with the wrist, there is a risk that the acquisition accuracy of biological information may be inferior. is there. In addition, when a wristwatch-type data chip is used, the worker may forget to reattach the data chip with the data chip removed during a break, etc., and return to work. There is a risk that it will not be possible.

  On the other hand, the advantages of the watch-type data chip are that the data chip itself is exposed and that the data chip has a certain thickness, so that the discomfort given to the operator is small. It is possible to adopt a mode in which the biometric information can be transmitted to the cloud server by directly connecting to the Internet without going through the biometric information transmitting unit.

  In the heat stroke risk management system of the present embodiment, the data chip attached to the undershirt is made smaller and lighter to eliminate the operator's uncomfortable feeling, and by using a stretchable material as the undershirt, the worker The electrode of the data chip is kept away from the surface of the operator's body even when the pose is bent forward. On the other hand, since priority was given to reducing the discomfort of the worker with respect to the mounting of the data chip in this way, as a result, the data chip is limited to short distance data transmission such as Bluetooth, and the transmission unit and the operating power source are reduced in size and weight. On the other hand, it is necessary for the worker to attach a portable terminal as a biological information transmitting unit in addition to the data chip.

  As described above, in the heat stroke risk management system according to the present embodiment, in addition to the function as a biological information transmitting unit that transmits the biological information obtained from the data chip, the portable terminal worn by the worker, By combining the functions of a warning notification unit that must be possessed by the operator, the number of devices held by the operator is reduced, and the burden during work is reduced.

  As described above, in the heat stroke risk management system according to the present embodiment, it has been described that a smartphone is used as a biological information transmission unit that transmits the biological data of the worker acquired by the biological information acquisition unit to the cloud server. . Smartphones can achieve more than a certain level of complexity by installing applications, and have the functions of smartphones that connect to the Internet to send and receive data. This is because the warning information can be easily notified through vibration or the like.

  Furthermore, when using a smartphone as a device that the worker equips in the heat stroke risk management system according to the present embodiment, it is also used as a means for the worker to grasp his / her health condition by displaying the biological information of the worker. be able to.

  FIG. 6 is a diagram showing a display example of the display screen of the mobile terminal equipped by the worker in the heat stroke risk management system according to the present embodiment.

  As shown in FIG. 6, the heart rate, body temperature (body surface temperature), sweating amount, etc. acquired by the data chip are displayed in real time as personal data of the worker (Mr. AAA) on the smartphone 12 which is a portable terminal. At the same time, whether each numerical value is rising or falling can be represented by an arrow. In addition, based on the resting data of the day, by displaying whether the basic physical condition is good or bad, the remaining battery level of the data chip and smartphone, and the cycle of biometric information update, You can keep track of your physical condition and the operating status of the heat stroke risk management system.

  In addition, for example, by displaying the determination result of the risk of developing heat stroke, it is possible to expect an effect of prompting the worker to actively manage his / her physical condition.

  Note that the display screen example of the smartphone shown in FIG. 6 is merely an example. For example, the amount of sweating is indicated by specific numerical values instead of ranks such as “high”, “medium”, and “low”. Needless to say, the contents and the title item itself can be changed as appropriate. Of course, there is no problem even if it is set not to display its own biometric information shown in FIG. 6 but to display a normal standby screen when warning display is not performed.

  Next, the screen display contents of the information equipment of the supervisor at the work site will be described.

  FIG. 7 is a diagram showing an example of a display screen of a notebook personal computer as an information terminal owned by the supervisor.

  As described above, in the heat stroke risk management system according to the present embodiment, the information terminal such as the laptop computer or tablet terminal of the site supervisor at the work site serves as an information management unit that generates warning information for the worker. Fulfills the function.

  The supervisor's information terminal is connected to a cloud server equipped with a heat stroke risk determination unit via the Internet, and can acquire biological information of a plurality of workers in real time.

  Utilizing this fact, as shown in FIG. 7, a list of workers (AAA, BBB, CCC, etc.) arranged at the site to be supervised is displayed, and the gender, age, etc. of each worker are displayed. In addition to the basic information, biological information such as body temperature (body surface temperature), heart rate, and sweating amount is displayed. In addition, by displaying special notes in the biometric information of individual workers and warning necessity information that is the basis for determining whether warning information should be issued in conjunction with an increased risk of developing heat stroke, Supervisors who have a strong responsibility for safety management can easily make decisions such as interrupting work as necessary.

  Further, by displaying information including information on the worker who is absent from work on the day or the worker who has been instructed to take a break due to an increased risk of heat stroke, the personnel management at the work site can be easily performed.

  In addition, for example, by displaying a list of each worker's data chip, smartphone battery capacity, and radio wave reception status, normal operation of the heat stroke risk management system, such as whether battery replacement is necessary or smartphone online / offline display, etc. Can grasp necessary information.

  The display screen of the supervisor's information terminal shown in FIG. 7 is merely an example. Also, on the management computer used by the administrator at the operator's office, for example, by displaying the same screen in a state that can be switched for each of the plurality of work sites, You can easily know if you are in good health.

  Hereinafter, modifications of the heat stroke risk management system of the present embodiment will be described.

  In the above-described embodiment, in the heat stroke risk management system disclosed in the present application, the worker exemplifies a configuration equipped with a biological information acquisition unit and a portable terminal including both a biological information transmission unit and a warning notification unit. However, this is not an essential requirement in the heat stroke risk management system disclosed in the present application.

  For example, when the above-described wristwatch type data chip is used, the biological information acquisition unit and the biological information transmission unit are provided in the wristwatch type data chip, and the warning notification unit is separately provided on the collar of the work clothes or the chest of the work clothes. It can be comprised with the member which can be arrange | positioned in the position which is easy to catch an operator's eyes, such as a pocket. Even in the case where the data chip as the biometric information acquisition unit is fixed to the undershirt, for example, the biometric information transmission unit is loaded on the buckle portion of the belt of the work pants, thereby giving a special burden to the worker. It is possible to realize a biometric data acquisition / transmission unit that can acquire biometric information and transmit it to the server without any problem. In this case, it is possible to connect the data chip attached to the undershirt and the biometric information transmitter built in the buckle of the belt by wire, and the data chip can be further reduced in thickness and weight. In these cases, it is preferable that the warning notification unit is arranged at a position where the operator can easily touch the operator's eyes on the surface of the work clothes such as the neck and the chest pocket portion of the work clothes as described above.

  Moreover, in the said embodiment, the example with which the heat stroke risk determination part was equipped with the server arrange | positioned on the internet as a network environment was shown. As described above, by arranging the heat stroke risk determination unit in the Internet environment, it is possible to simultaneously receive biological information of a plurality of workers and determine the risk of developing heat stroke for each worker. it can. By doing in this way, as above-mentioned, the information of many workers can always be acquired and it can utilize as the newest environmental data in the heat stroke onset risk judgment of each worker.

  In addition, by concentrating data on a server on the Internet, there is no problem regarding the actual location of the worker in an environment connected to the Internet. For this reason, it is particularly suitable when the worker's work position changes as in the transportation industry, or when managing workers at several different work sites at once.

  Also, by gathering the worker's biometric information centrally on a server on the Internet, the data of each worker can be easily utilized as so-called big data. For this reason, the obtained individual worker data can be used as worker information related to heat stroke as valuable data for heat stroke research in a medical institution or administrative organization.

  However, the heat stroke risk determination unit in the heat stroke risk management system disclosed in the present application is to determine the worker's risk of developing heat stroke based on the biological information at rest of the worker and the biological information at work. As long as there is no restriction on the location, it is not an essential requirement to be installed in a server located on the Internet.

  For this reason, according to the smallest system system, the heat stroke risk determination unit can be arranged in the portable terminal owned by the worker. In this case, since the biometric information acquisition unit and the heat stroke risk determination unit can be arranged at close positions, for example, by arranging a fine microcomputer chip in the wristwatch type biometric information acquisition unit, An integrated wearable device that also has a disease onset risk determination unit can be realized.

  When the heat stroke risk determination unit is realized as a wearable device worn by an operator, it may be difficult to arrange a data recording unit having a sufficient capacity due to the size restriction of the device. In this case, by making the wearable device connectable to the Internet, the worker's biometric information is stored in other information devices such as the supervisor's information device and the office data server via the Internet each time data is acquired. In addition, history information, weather information, biological information of other workers, and the like that are referred to when determining the risk of developing heat stroke can be acquired via the Internet. In this way, the determination accuracy in the heat stroke risk determination unit can be improved.

  In this case, a warning notification unit that notifies the worker of the warning information can also be arranged in the wearable device attached to the worker. As described above, in the ultimate case, the entire heat stroke risk management system disclosed in the present application can be physically arranged and formed in one device.
