Description

[Technical Field]

[0001] The present invention relates to a monitoring system in which a manager monitors a person under management. [Background technology]

[0002] Japanese Patent No. 6993857 (Patent Document 1) discloses a health management system that enables a manager to manage the health of a person under management. In this health management system, as shown in

[0112] and Figure 9, the evaluation value of WBGT (Wet Bulb Globe Temperature), which is an evaluation value for the risk of developing heatstroke, is displayed on the administrator display screen.

[0003] Furthermore, Japanese Patent No. 7195115 (Patent Document 2) discloses a heatstroke monitoring system that increases and decreases an alarm value, which is a threshold value for determining whether or not to send an alarm related to heatstroke. In this heatstroke monitoring system, as described in

[0043] , the alarm value goes up or down depending on whether or not the personnel working there have acclimatized to the heat. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6993857 [Patent Document 2] Patent No. 7195115 Summary of the Invention [Problem to be solved by the invention]

[0005] The above health management system uses the WBGT value itself. The WBGT value is a strict value specified by JIS, and it is time-consuming to obtain it for each person under management. Furthermore, the above-mentioned health management system does not take into consideration the heat acclimatization of the supervised personnel, and therefore excessive management may be applied to the supervised personnel after they have acclimatized to the heat, causing them to leave work early, which could result in an unnecessary shortage of personnel. In the heatstroke monitoring system, it is disclosed that the warning value will rise or fall depending on whether or not the person has heat acclimatized, but no further details are disclosed, and it is unclear how specifically the presence or absence of heat acclimatization is determined and to what extent the warning value will be raised or lowered.

[0006] Therefore, one of the main objects of the present invention is to provide a less time-consuming monitoring system. Furthermore, another main object of the present invention is to provide a monitoring system that can effectively reflect heat acclimatization in the monitoring of managed individuals, thereby better balancing personnel deployment and management. [Means for solving the problem]

[0007] This specification discloses a monitoring system. This monitoring system may be a system that monitors workers who are under supervision. The monitoring system may include a server 4 as a computer. The server may include a server communication unit. The server may include a server control unit. The server communication unit may be capable of receiving temperature information indicating the temperature around the worker. The server communication unit may be capable of receiving humidity information indicating the humidity around the worker. The server control unit may calculate a heat index, which is a function of the temperature and humidity, from the temperature information and the humidity information. When the server control unit determines that a predetermined condition related to the heat index is satisfied, it may generate warning message information related to the possibility of heat stroke. [Effects of the Invention]

[0008] One of the main advantages of the present invention is that it provides a less labor-intensive monitoring system. Furthermore, another major effect of the present invention is that a monitoring system is provided that can effectively reflect heat acclimatization in the monitoring of individuals under supervision, thereby better balancing personnel deployment and management.

[0015] The housing 10 holds other parts of the mobile terminal 2 directly or indirectly. The size of the housing 10 is such that it can fit into an adult's pocket, although the size of the housing 10 does not have to be such that it can fit into an adult's pocket.

[0016] The mobile terminal storage unit 11 can store various types of information. For example, the mobile terminal storage unit 11 is a random access memory and / or a temporary or non-transitory computer-readable storage medium. A mobile terminal control program PP is stored in the mobile terminal storage unit 11.

Note that the mobile terminal control program PP may be stored in the mobile terminal storage unit 11 by a method other than being read from a non-transitory computer-readable storage medium. For example, the mobile terminal control program PP may be non-transitoryly formed in the mobile terminal storage unit 11 when the mobile terminal storage unit 11 is manufactured.

[0017] The position information acquisition unit 12 acquires position information relation information RI transmitted by radio waves from one or more positioning satellites. The position information relation information RI is information from which the position information PI can be calculated. Note that the position information acquisition unit 12 may also receive the position information PI directly from one or more positioning satellites. The position information PI is information relating to the position of the mobile terminal 2. The position information relation information RI is, for example, satellite identification information and radio wave transmission time. The positioning satellite is, for example, at least one of a GPS (Global Positioning System) and a Quasi-Zenith Satellite System (QZSS).

[0018] The temperature acquisition unit 14 is a sensor that acquires temperature information TI, which is information relating to the ambient temperature.

The temperature acquisition unit 14 and the humidity acquisition unit 16 may be a single sensor.

[0019] The acceleration acquisition unit 18 acquires acceleration information AI relating to the acceleration of the mobile terminal 2. The acceleration information AI includes information about three types of acceleration on three axes. The three axes are the X-axis, Y-axis, and Z-axis, which are perpendicular to each other. The three types of acceleration are the X-axis acceleration, the Y-axis acceleration, and the Z-axis acceleration. The acceleration acquisition unit 18 may acquire acceleration information AI on axes other than the X-axis, Y-axis, and Z-axis, or may acquire acceleration information AI on two or fewer axes or four or more axes.

The mobile terminal communication unit 20 is capable of communicating both outdoors and indoors. The mobile terminal communication unit 20 may be capable of communicating directly with the Internet IN, or may be capable of communicating via at least one of local area communication and short-range communication, or may be capable of communicating with other networks such as a dedicated network instead of or in addition to the Internet IN. The mobile terminal 2 may also be equipped with a communication strength display unit that displays the strength of the radio waves from the mobile communication network. Furthermore, the mobile terminal 2 may be divided into multiple devices. For example, the mobile terminal 2 may include an information acquisition device that has components other than the mobile terminal communication unit 20, and a communication device that is capable of short-range communication with the information acquisition device and performs the same functions as the mobile terminal communication unit 20. In addition, communication may be wireless or wired, and the same applies to various types of communication described below.

[0021] The battery 22 is a rechargeable secondary battery and is housed within the housing 10 . The battery 22 is charged by connecting a power line to a terminal (not shown). The battery 22 is a power source for each part of the mobile terminal 2 except for the housing 10 . The portable terminal 2 may be provided with a battery remaining capacity display unit that displays the remaining capacity of the battery 22. The battery remaining capacity display unit and the communication strength display unit may be included in a single portable terminal display unit. The battery 22 may be a primary battery, or may be detachable from a battery storage unit provided in the housing 10.

[0022] The mobile terminal control unit 24 controls each unit in the mobile terminal 2. The mobile terminal control unit 24 is a CPU (Central Processing Unit). The mobile terminal control unit 24 executes a mobile terminal control program PP. Note that the mobile terminal control unit 24 may be something other than a CPU. The mobile terminal control unit 24 calculates the position information PI from the position information relation information RI and stores it in the mobile terminal storage unit 11. The position information PI is longitude and latitude. The position information PI may be calculated in the position information acquisition unit 12. The position information relation information RI may also be stored in the mobile terminal storage unit 11. Furthermore, the position information PI may be three-dimensional information that includes altitude information, or may be expressed in a format other than latitude and longitude. The mobile terminal control unit 24 stores the temperature information TI, humidity information HI, and acceleration information AI in the mobile terminal storage unit 11 in association with the acquisition time RT. The mobile terminal control unit 24 controls communication in the mobile terminal communication unit 20 . The mobile terminal control unit 24 grasps a value indicating the remaining capacity of the battery 22, generates battery remaining capacity information BI that is information indicating the remaining capacity of the battery 22, and stores the information in the mobile terminal storage unit 11. Note that the battery remaining capacity information BI may be the value indicating the remaining capacity of the battery 22 itself, or may be different from the value.

[0023] The server 4 is a server computer, and is communicably connected to the mobile terminals 2 and the management terminal 6 via the Internet IN. The server 4 is installed in the office of the organization that manages the mobile terminals 2. The server 4 has a server storage unit 30 as a computer storage unit, a server communication unit 32 as a computer communication unit, and a server control unit 34 as a computer control unit. The server 4 may be integrated with the management terminal 6. The server 4 may also be installed in the organization to which the administrator belongs, just like the management terminal 6. Furthermore, multiple servers 4 may be provided. The multiple servers 4 may be installed in the same office, in different offices, or in different organizations.

[0024] The server storage unit 30 can store various types of information. For example, server storage 30 may be a random access memory and / or a temporary or non-transitory computer-readable storage medium. A server control program SP is stored in the server storage unit 30. The server control program SP is formed in the server storage unit 30 by being read from a non-transitory computer-readable storage medium. The server control program SP is recorded in the non-transitory computer-readable storage medium. The server control program SP has a function of controlling the server 4. The server control program SP contains a set of instructions that cause the functions described below to be performed. Note that the server control program SP may be stored in the server storage unit 30 by a method other than reading from a non-transitory computer-readable storage medium.

[0028] The management terminal storage unit 40 can store various types of information. For example, the management terminal storage unit 40 is at least one of a random access memory and a temporary or non-temporary computer-readable storage medium. A management terminal control program MP is stored in the management terminal storage unit 40. The management terminal control program MP is formed in the management terminal storage unit 40 by being read from a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium has the management terminal control program MP recorded therein. The management terminal control program MP has the function of controlling the management terminal 6. The management terminal control program MP contains a set of instructions that cause the functions described below to be performed. Note that the management terminal control program MP may also be stored in the management terminal storage unit 40 by a method other than being read from a non-transitory computer-readable storage medium. For example, the management terminal control program MP may be non-transitoryly formed in the management terminal storage unit 40 when the management terminal storage unit 40 is manufactured.

[0029] The management terminal input unit 42 is a section for inputting various types of information. The management terminal input unit 42 is, for example, at least one of a keyboard, a pointing device, a microphone, and a switch.

[0030] The management terminal display unit 44 is a section that displays various types of information. The management terminal display unit 44 can be viewed by the administrator. The management terminal display unit 44 is, for example, at least one of a monitor, a printer, and a speaker. The management terminal input unit 42 and the management terminal display unit 44 may be integrated into one unit, such as a touch panel.

[0031] The management terminal communication unit 46 is capable of communicating with the Internet IN. Furthermore, the server communication unit 32 may be capable of communicating via at least one of local communication and short-range communication, and may be capable of communicating with other networks such as a dedicated network instead of or in addition to the Internet IN.

[0032] The management terminal control unit 48 controls each unit in the management terminal 6. The management terminal control unit 48 is a CPU.

Incidentally, a part or all of the server 4 may be integrated into the management terminal 6. A part or all of the server control program SP may be integrated into the management terminal control program MP.

[0033] An example of the operation of such a monitoring system 1 will be described below. The monitoring system 1 is capable of monitoring multiple people, including several dozen people. For simplicity of explanation, the following operation example will mainly describe the monitoring of one worker. Monitoring of multiple workers can be achieved by each mobile terminal 2 individually performing the same operations as those of the mobile terminal 2 described below. In this case, a unique mobile terminal identification information ID is assigned to each mobile terminal 2, and the following processing is performed for each mobile terminal identification information ID. The mobile terminal identification information ID is stored in the mobile terminal storage unit 11.

[0034] 2 and 3A are flowcharts relating to this operation example. The portable terminal 2 is carried by the worker. The manager keeps track of the correspondence between each worker and the portable terminal identification information ID of the portable terminal 2 carried by the worker. The manager obtains a profile of the worker corresponding to the mobile device identification information ID. The profile includes the worker's weight, the exercise intensity of the work performed by the worker, and the worker's heat acclimation status. The heat acclimation status indicates whether the worker has become accustomed to the heat. The heat acclimation status can be either "acclimatized" or "unacclimatized." If the worker has worked during the daytime with a maximum temperature of a predetermined temperature (e.g., 30°C) or higher for a predetermined number of days (e.g., 15 days) from late spring to early summer, the heat acclimation status is switched from "unacclimatized" to "acclimatized." Note that the profile may be a combination of these, and may also include, for example, the worker's medical history. The worker's medical history may include at least one of diabetes and heart disease, which are more closely related to the likelihood of heatstroke than other illnesses. Furthermore, at least one of the type of heat acclimation status and the switching condition may be other than those described above. For example, heat acclimation status may be expressed in three or more stages. The manager inputs the worker's profile into the management terminal input unit 42 of the management terminal 6. The management terminal control unit 48 generates profile information FI based on the input profile. The profile information FI includes weight information WE, which is information related to weight, exercise intensity information MT, which is information related to exercise intensity, and heat acclimatization information HA, which is information related to the worker's heat acclimatization status. Note that the profile information FI may be a combination of information other than these, and may also include, for example, medical history information, which is information related to the worker's medical history. Then, the management terminal control unit 48 transmits the profile information FI related to the mobile terminal identification information ID to the server 4 via the management terminal communication unit 46 (step S1). When the server control unit 34 recognizes that the server communication unit 32 has received the profile information FI, the server control unit 34 stores the profile information FI in the server storage unit 30 in association with the corresponding mobile terminal identification information ID (step S2). Steps S1 and S2 only need to be performed the first time if the same mobile device 2 is always provided to each worker and there are no changes to the profile. If at least one of the mobile device 2 provided to the worker and the profile is changed, the manager must redo steps S1 and S2 for at least the changed parts. The management terminal control unit 48 may store the profile information FI related to the mobile terminal identification information ID in the management terminal storage unit 40. The manager may also directly input the profile information FI. Furthermore, some or all of the input performed by the manager may be performed by someone else, such as a worker. Furthermore, the generation of the profile information FI from the profile may be performed by the server 4.

[0035] The worker or manager turns on the power of the mobile terminal 2 (step S3). The mobile terminal control unit 24 of the mobile terminal 2 executes the mobile terminal control program PP and performs initial settings.

[0036] Then, the mobile terminal control unit 24, which executes the mobile terminal control program PP, acquires worker information OI, which is various information related to the worker, at a predetermined timing (for example, every fixed time from when the power is turned on), and calculates position information PI from the position information relationship information RI (step S4-1). That is, the mobile terminal control unit 24 acquires position information relationship information RI from the position information acquisition unit 12 and calculates position information PI. The mobile terminal control unit 24 also acquires temperature information TI from the temperature acquisition unit 14. The mobile terminal control unit 24 also acquires humidity information HI from the humidity acquisition unit 16. The mobile terminal control unit 24 also acquires acceleration information AI from the acceleration acquisition unit 18. In addition, the mobile terminal control unit 24 acquires remaining battery information BI from the battery 22. The worker information OI includes position information relationship information RI, position information PI, temperature information TI, humidity information HI, acceleration information AI, and remaining battery information BI. Note that the worker information OI may not include some of this information, or may include other information. Hereinafter, a plurality of processes performed at predetermined timings may be collectively referred to as step S4. The predetermined timing may be every predetermined time (for example, 00, 10, 20, 30, 40, and 50 minutes past the hour). The predetermined timing may also differ depending on the type of information. For example, the location information relationship information RI may be acquired and the location information PI may be calculated every 5 minutes, and other information may be acquired every 10 minutes. Alternatively, the location information relationship information RI may be acquired and the location information PI may be calculated at regular intervals, and other information may be acquired when the difference in location from the previous location information PI is equal to or greater than a predetermined threshold.

[0037] Furthermore, an example of a predetermined timing for acquiring worker information OI will be described in detail. The predetermined timing can be specified in one-minute increments, for example, from every minute to every 24 hours. The more frequently the predetermined timing occurs, the higher the accuracy of the worker information OI and the accuracy of the calculation worker information CI and display information DI generated based on the worker information OI become, but the battery 22 becomes more drained. For example, if the specified timing is set to every minute, the worker information OI can be obtained in great detail, but the battery 22 needs to be charged every two days. If the specified timing is set to every hour, the accuracy of the worker information OI will be lower than when the specified timing is set to every minute, but the battery 22 will only need to be charged every 17 days.

[0038] Next, the mobile terminal control unit 24 associates the acquired or calculated worker information OI with the acquisition time RT and stores the information in the mobile terminal storage unit 11 (step S4-2). That is, the positional relationship information RI, the positional information PI, the temperature information TI, the humidity information HI, the acceleration information AI, and the remaining battery amount information BI are stored in the mobile terminal storage unit 11 for each acquisition time RT.

[0039] Next, the mobile terminal control unit 24 transmits the stored worker information OI, acquisition time RT, and mobile terminal identification information ID to the server 4 via the mobile terminal communication unit 20 and the Internet IN (step S4-3). That is, the positional relationship information RI, the positional information PI, the temperature information TI, the humidity information HI, the acceleration information AI, the remaining battery amount information BI, the acquisition time RT, and the mobile terminal identification information ID are transmitted to the server 4. The worker information OI may be transmitted in parallel with or prior to storage in the mobile device storage unit 11. The worker information OI may also be transmitted collectively for multiple sets of information related to multiple acquisition times RT. In this case, the frequency of transmission of the worker information OI is lower than the frequency of acquisition of the worker information OI. Alternatively, the worker information OI may be transmitted when a mobile device information transmission request signal is received from at least one of the server 4 and the management terminal 6. The mobile device information transmission request signal requests the mobile device 2 to transmit worker information OI related to the acquisition time RT that has not yet been transmitted to the server 4. In addition, the mobile device identification information ID may be stored together with the worker information OI for each acquisition time RT, or may be transmitted only when the worker information OI is transmitted at a specific timing, such as the first time. Furthermore, some or all of the transmitted information may be encrypted. Such encryption may also be performed for some or all other communications.

[0040] The server control unit 34 of the server 4 executes the server control program SP, and when the server communication unit 32 receives the worker information OI, acquisition time RT, and mobile terminal identification information ID, it stores these in the server memory unit 30 for each mobile terminal identification information ID (step S4-4). That is, the location information relation information RI, location information PI, temperature information TI, humidity information HI, acceleration information AI, and remaining battery information BI are stored in the server storage unit 30 for each mobile terminal identification information ID and for each acquisition time RT. Furthermore, when the mobile terminal identification information ID is transmitted from the mobile terminal 2 only at specific times, the server control unit 34 may refer to the communication records of the destination, etc. in the server communication unit 32 and store the received information as related to the corresponding mobile terminal identification information ID.

[0041] Furthermore, as will be described in detail later, when an information processing condition, which is a predetermined condition related to the processing of the worker information OI, is satisfied, the server control unit 34 processes the worker information OI (step S5). The information processing condition is, for example, at least one of when a predetermined number of sets of worker information OI relating to different acquisition times RT are obtained and when a predetermined time such as the end of work time arrives. Note that the information processing condition may or may not depend on the type of worker information OI. The processing of the worker information OI also includes generating display information DI, which is information for displaying the worker information on the management terminal display unit 44 of the management terminal 6. The display information DI includes, for example, at least one of graph information GI, which is information related to the graph GR for the worker information OI, and warning message information WI, which is information related to the warning message WM issued when a predetermined warning condition is met. The server control unit 34 stores the generated display information DI in the server storage unit 30. The processing of the worker information OI also includes generating calculation worker information CI using the predetermined worker information OI. The server control unit 34 stores the generated calculation worker information CI in the server storage unit 30. The calculation worker information CI is, for example, a heat index WB calculated from temperature information TI and humidity information HI. The calculation worker information CI is, for example, a reference value RAL for determining metabolic heat before heat acclimation and a reference value REL for determining metabolic heat after heat acclimation, which are calculated from at least one of weight information WE and exercise intensity information MT. The weight information WE indicates the weight of the worker. The exercise intensity information MT indicates the intensity of the exercise performed by the worker. For example, if the work involves sitting at a desk, the value is 2, and if the work involves light exercise, such as walking, the value is 3. Note that some or all of the display information DI may be generated when a server-side information display request signal, which is a signal requesting the display of information, is received from the management terminal 6. For example, when a server-side worker information display request signal, which is a signal requesting the display of worker information OI specifying at least one of one or more mobile terminal identification information IDs and the type of worker information OI, is received from the management terminal 6, the designated worker information OI may be generated. Furthermore, when the display information DI is immediately sent to the management terminal 6, the display information DI does not need to be stored in the server storage unit 30. Furthermore, at least one of the generation and storage of the calculation worker information CI may be omitted. Furthermore, at least one of the reference value RAL for determining metabolic heat before heat acclimation and the reference value REL for determining metabolic heat after heat acclimation may be generated from medical history information instead of or in addition to at least one of the weight information WE and the exercise intensity information MT.

[0042] Furthermore, the server control unit 34 transmits the display information DI to the management terminal 6 (step S6). The display information DI may include only either the graph information GI or the warning message information WI. The display information DI may also include, instead of or in addition to the graph information GI and the warning message information WI, information such as a table relating to the numerical values ​​of the worker information OI and the acquisition time RT.

[0043] The management terminal control unit 48 of the management terminal 6 executes the management terminal control program MP, and when the management terminal communication unit 46 receives the display information DI, it displays on the management terminal display unit 44 based on the display information DI (step S7). The management terminal control unit 48 generates a graph GR based on the graph information GI, stores the generated graph GR for each mobile terminal identification information ID in the management terminal storage unit 40, and displays it on the management terminal display unit 44. In addition, the management terminal control unit 48 generates a warning message WM based on the warning message information WI, stores the generated warning message WM in the management terminal memory unit 40 for each mobile terminal identification information ID, and displays it on the management terminal display unit 44. The management terminal control unit 48 may store at least one of the graph information GI and the warning message information WI in the management terminal storage unit 40.

[0044] For example, the graph information GI is a numerical sequence related to the worker information OI, and the graph GR is drawn based on the numerical sequence. Note that the graph information GI and the graph GR may be the same. Moreover, the warning message information WI is message identification information such as a numerical value, and the warning message WM is generated in accordance with the message identification information in the management terminal 6. Note that the warning message information WI and the warning message WM may be the same.

[0045] Note that part or all of the generation of the display information DI based on the worker information OI may be performed by the management terminal 6. For example, the management terminal 6 may receive the worker information OI as is, generate and store graph information GI based on the worker information OI, and obtain a graph GR from the graph information GI in response to a display request. Furthermore, based on a predetermined input from the management terminal input unit 42 by the administrator, content based on only a portion of the display information DI may be displayed, or the display content based on the displayed display information DI may be switched. For example, only a portion of the worker information OI may be displayed, or only a specific mobile terminal identification information ID, i.e., worker information OI related to a specific worker, may be displayed. The type of information in the display information DI that is the basis for the display content may differ for each mobile terminal identification information ID or its group. Furthermore, the above-mentioned server information display request signal may include one or more mobile terminal identification information IDs for specifying the type of mobile terminal 2 carried by the worker, and a display related to the mobile terminal identification information IDs may be displayed on the management terminal 6. Furthermore, the server information display request signal may include a specification of the type of worker information OI, and a display related to the type may be displayed on the management terminal 6. On the other hand, the server 4 may generate at least one of the graph GR from the graph information GI and the warning message WM from the warning message information WI. When both of these are generated, for example, the server control unit 34 transmits the graph GR and the warning message WM to the management terminal 6. The management terminal 6 displays the received graph GR and warning message WM directly on the management terminal display unit 44.

[0046] Step S5 relating to the processing of worker information OI will be described in detail below. Note that the information processing condition determination timing, which is the timing for determining whether or not the information processing condition is satisfied, and the information processing execution timing, which is the timing for executing processing when the information processing condition is satisfied, may be in the order described below, or may be in a different order, or may be performed in parallel. Fig. 4 is a flowchart showing the details of step S5. Fig. 5 is a schematic diagram of the management terminal display unit 44 displaying a graph GR in step S7 based on various graph information GI generated based on the worker information OI processed in step S5. In Figure 5, various types of graph information GI relating to three worker information OI are displayed in a list. Note that the list may be displayed for two or fewer workers or for four or more workers, and the types of worker information OI may be displayed in a combination other than that shown in the figure. The combination of types of worker information OI in the list may be different for each worker.

[0047] FIG. 6 is a schematic diagram of the management terminal display unit 44 displaying a graph GR relating to battery remaining capacity information BI for one worker. In step S5, the server control unit 34 refers to the battery remaining amount information BI and generates graph information GI of the battery remaining amount information BI as a type of display information DI (step S5-1). 6, the horizontal axis of the graph GR based on the graph information GI represents the date and time, spanning approximately 10 days. The vertical axis of the graph GR based on the graph information GI represents the remaining charge of the battery 22, with 3 indicating a high remaining charge, 1 indicating a low remaining charge, 2 indicating a state between 1 and 3, 0 indicating no remaining charge, and -1 indicating the charging state. Note that when the battery remaining charge information DI is 0, the mobile terminal 2 becomes inoperable, and immediately thereafter worker information OI and the like cannot be recorded. The graph GR of the battery remaining capacity information BI in Figure 6 shows that the worker basically operates the portable terminal 2 with a large amount of remaining capacity in the battery 22, and also charges the battery 22 when returning home each day.

[0048] FIG. 7 is a schematic diagram of the management terminal display unit 44 displaying a graph GR relating to temperature information TI and humidity information HI for one worker. In step S5, the server control unit 34 references the temperature information TI and the humidity information HI and generates graph information GI of the temperature information TI and the humidity information HI as a type of display information DI (step S5-2). Note that the graph information GI of the temperature information TI and the graph information GI of the humidity information HI may be generated separately. Alternatively, the graph information GI may be generated by combining any information related to the worker information OI. 7, the horizontal axis of the graph GR based on the graph information GI represents the date and time, and spans approximately half a day, corresponding to the daytime when workers are working. The vertical axis of the graph GR based on the graph information GI represents the temperature (°C) and humidity (%). In the graph GR in Figure 7, the temperature information TI is indicated by the lower broken line. The temperature begins to rise after 8:15, when the worker takes the mobile terminal 2 out of its storage location and carries it with him. The worker carries the mobile terminal 2, for example, by putting it in the breast pocket of his clothes. The temperature also reaches its highest point of the day, 36°C, around 1:00 PM. On the other hand, the humidity information HI is shown by the upper broken line. The humidity on this day was generally high at over 70%, but there were sudden drops at around 1:15 PM and 2:30 PM. These drops in humidity correspond to workers finishing their outdoor work, getting into their cars, and turning on their car air conditioners.

[0049] FIG. 8 is a schematic diagram of the management terminal display unit 44 displaying a graph GR relating to acceleration information AI of one worker. In step S5, the server control unit 34 refers to the acceleration information AI and generates graph information GI relating to the acceleration information AI as a type of display information DI (step S5-3). In the case of Figure 8, the horizontal axis of the graph GR based on the graph information GI represents the date and time, spanning approximately two days. The vertical axis of the graph GR based on the graph information GI represents the displacement of acceleration (cm per second). Since the acceleration of gravity is 980 cm per second, when the absolute value of the acceleration displacement is 1000 cm per second or less, that is, when the acceleration displacement is within the range of -1000 to 1000, it can be said that this is the acceleration displacement that typically occurs to workers. In Fig. 8, the acceleration displacement is plotted for each of the three axes, i.e., the X-axis, Y-axis, and Z-axis. For the time period from 6:00 to 9:00 in Fig. 8, the upper broken line corresponds to the Y-axis, the middle broken line corresponds to the X-axis, and the lower broken line corresponds to the Z-axis. Note that the acceleration displacement may be plotted in a format other than for each of the three axes, such as being shown as the sum or average of the three axes. Furthermore, the acceleration acquisition unit 18 of the mobile terminal 2 may acquire acceleration displacement information related to the acceleration displacement. In Figure 8, the acceleration displacement is generally within the range of -1000 to 1000, but at around 1:30 PM on August 23rd, it reaches a maximum value of approximately 3000 on the X-axis. This maximum value corresponds to the impact when the worker gets into the car. Also, at around 2:30 PM on August 24th, it reaches a minimum value of approximately -8000 on the X-axis. This minimum value corresponds to the impact when the worker climbs over the fence.

[0050] Figure 9 is a schematic diagram of the management terminal display unit 44 displaying a graph GR relating to the heat index WG for one worker, as well as the reference value RAL for determining metabolic heat before heat acclimatization and the reference value REL for determining metabolic heat after heat acclimatization. In step S5, the server control unit 34 refers to the temperature information TI and the humidity information HI and calculates the heat index WG (step S5-4). The heat index WG is a simplified version of the WBGT, i.e., a simplified WGBT. The WGBT is calculated by multiplying the wet bulb temperature T w , black bulb temperature T g , dry bulb temperature T n is a function of and is expressed by the following equation (1). WGBT=0.7T w +0.2T g +0.1T n ··(1) In contrast, the simplified WGBT is a function of temperature T and humidity H. Here, it is obtained by applying temperature T and humidity H to the simplified indoor WBGT estimation chart Ver. 4 (Japanese Society of Biometeorology: Guidelines for Preventing Heatstroke in Daily Life Ver. 4, 2022, table format), which is a simplified estimation of WBGT for indoor spaces without solar radiation, and then multiplying the value of the simplified indoor WBGT using a specified formula. By using this formula, the simplified indoor WBGT value can be used with a margin of error even when working outdoors or in sunlight. The specified formula is, for example, the following formula (2), where the simplified indoor WBGT value is multiplied by a specified factor greater than 1 (e.g., 1.05). The simplified WGBT is in °C, similar to the WGBT. Simple WGBT = Simple WBGT for indoor use × specified magnification (2) Here, the temperature T is acquired as temperature information TI by the temperature acquisition unit 14, and the wet-bulb temperature T w Instead, the black globe temperature T g Not the dry bulb temperature T n The temperature acquisition unit 14 acquires the temperature information TI in a dry manner. w The measurement of the dry-bulb temperature T n Compared to the measurement of the black globe temperature T, the humidity of the temperature measurement area must be kept high, which is time-consuming. g The measurement of the dry-bulb temperature Tn Compared to the measurement of temperature, the temperature measurement part must be covered with a black film, which is more time-consuming. The simplified WGBT may be a function of temperature T and humidity H other than those described above, and the indoor simplified WBGT need not be used. The indoor simplified WBGT may be in a format other than a table. The predetermined formula for increasing the value of the indoor simplified WBGT may be one that adds a predetermined value, etc. Furthermore, the heat index WG may be a value other than the simplified WGBT.

[0051] Furthermore, the server control unit 34 refers to the weight information WE and the exercise intensity information MT to calculate the reference value for metabolic heat, and stores it in the server storage unit 30 as a type of calculation worker information CI (step S5-5).

[0052] Among the reference values ​​for metabolic heat, the reference value for metabolic heat before heat acclimation, RAL, is calculated using the following formulas (3) and (4). Note that exercise intensity has no unit, body weight is measured in kg, and RAL is measured in °C because it is an index for comparison with the simplified WGBT. M=exercise intensity x body weight (3) RAL = 59.9 - 14.1 × log 10 M (4) For example, if the exercise intensity is 3.0 and the body weight is 70 kg, the RAL is given by the following formula (5). RAL = 59.9 - 14.1 × log 10 (3.0×70)=27.157 (5)

[0053] On the other hand, the reference value REL for metabolic heat after heat acclimation is calculated using formula (3) and the following formula (6). REL=56.7-11.5×log 10 M (6) For example, when the exercise intensity is 3.0 and the body weight is 70 kg, REL is given by the following formula (7). REL=56.7-11.5×log 10 (3.0×70)=29.994 (7) The server control unit 34 may calculate only one of the RAL and the REL based on the heat acclimation information HA. Alternatively, at least one of the RAL and the REL may be calculated by further taking into account medical history information. For example, weighting, i.e., points, may be assigned depending on the type of medical history information, and at least one of the RAL and the REL may be reduced depending on the total value of the points. Such reduction may be achieved by multiplying the RAL, etc. before taking into account the medical history information, by a predetermined value less than 1, by subtracting a specific value, or by a combination of these.

[0054] Then, the server control unit 34 generates graph information GI relating to the heat index WG and RAL and REL as a type of display information DI (step S5-6). 9, the horizontal axis of the graph GR based on the graph information GI is the date and time, covering approximately four and a half hours in the evening, and the vertical axis of the graph GR based on the graph information GI is the value of the simplified WGBT, or RAL, REL. 9 shows the metabolic heat reference value RAL before heat acclimation (horizontal line at 27.157), the metabolic heat reference value REL after heat acclimation (horizontal line at 29.994), and the heat index WG (broken line). Note that depending on the heat acclimation information HA, only one of RAL and REL may be plotted. In FIG. 9, the metabolic heat after heat acclimation exceeds the reference value during the period from 17:10 to 17:54.

[0055] FIG. 10 is a schematic diagram of the management terminal display unit 44 displaying a graph GR relating to position information PI relating to one worker. In step S5, the server control unit 34 refers to the position information PI and generates graph information GI related to the position information PI as a type of display information DI (step S5-7). In the case of Fig. 10, a map is displayed as the background of a graph GR based on graph information GI, and the position information PI is indicated by a marker on the map. Here, the marker is a filled circle. In the case of Fig. 10, there is a plurality of pieces of position information PI at different acquisition times RT, and therefore, in Fig. 10, a plurality of markers are displayed as the history of the position information PI. Note that the markers may be shapes other than filled circles, such as unfilled polygons.

[0056] Although FIG. 10 is grayscaled, the marker color is actually blue (black circles in FIG. 10) or red (white circles in FIG. 10). When the humidity indicated by the humidity information HI related to the same acquisition time RT as the position information PI is less than a predetermined value (e.g., 80%), the marker color is blue. On the other hand, when the humidity indicated by the humidity information HI related to the same acquisition time RT as the position information PI is equal to or greater than a predetermined value, the marker color is red. Note that the marker color may be other than blue or red, and three or more colors may be used to indicate three or more levels of humidity. The size of the marker is displayed according to the temperature indicated by the temperature information TI. These changes in the color and size of the markers make it easier for workers to understand the temperature and humidity in their environment. Temperature and humidity are important factors that affect the likelihood of heatstroke, and the higher both the temperature and humidity, the higher the likelihood of heatstroke. In the case of Figure 10, the appearance of the eye-catching, large red marker makes it easier to understand the increased likelihood of heatstroke. Note that different temperatures may be indicated by different colors of the markers, and different humidity levels may be indicated by different sizes of the markers. Different temperatures or humidity levels may be indicated by changing the type of shape of the markers. Different markers may also indicate differences in factors other than temperature and humidity, such as differences in workers (mobile terminal identification information IDs).

[0057] Furthermore, the server control unit 34 determines whether the following several types of warning conditions are met, and generates warning message information WI when the conditions are met. The warning conditions and warning message information WI are not limited to those listed below. The order in which various warning conditions are determined is also not limited to those listed below. Determination of multiple warning conditions may be performed simultaneously.

[0058] That is, first, the server control unit 34 determines whether a warning condition regarding the heat index WB exists (step S5-8). The warning condition for the heat index WB is that the heat index WG remains equal to or greater than the metabolic heat reference value for a predetermined time (e.g., 30 minutes). Here, the metabolic heat reference value is determined based on the heat acclimation information HA, and is either the metabolic heat reference value RAL before heat acclimation or the metabolic heat reference value REL after heat acclimation. The warning condition for the heat index WB may also vary based on medical history information. For example, the predetermined time period related to continuity may be shortened based on the total number of points in the medical history information. The shortening of the time period may involve multiplying the predetermined time period before taking into account the medical history information by a predetermined value less than 1, subtracting a specific time period, or a combination of these. If the answer to step S5-8 is Yes, the server control unit 34 determines that the warning condition regarding the heat index WB is satisfied, and generates warning message information WI regarding the possibility of heatstroke, indicating that the risk of heatstroke occurring to the worker is high and that the possibility of heatstroke occurring is relatively high (step S5-9).The server control unit 34 then proceeds to step S5-10. On the other hand, if the answer is No in step S5-8, the server control unit 34 skips step S5-9 and proceeds to step S5-10.

[0059] Next, the server control unit 34 determines whether a warning condition regarding the possibility of immobility is met (step S5-10). The warning condition for the possibility of immobility has the following two elements. That is, the first element of the warning condition is that the absolute value of the acceleration displacement indicated by the acceleration information AI exceeds a predetermined value (e.g., 1000 cm per second). The second element of the warning condition is that the positions indicated by each piece of position information PI fall within a predetermined range (e.g., 100 m square) for a specific period of time (e.g., 20 minutes) or more. The warning condition is satisfied when the second element is satisfied during the period from when the first element is satisfied until the predetermined period of time (e.g., one hour) has elapsed. If the answer is Yes in step S5-10, the server control unit 34 determines that the warning condition regarding the possibility of immobility is satisfied, and generates warning message information WI regarding the possibility of immobility, assuming that there is a high risk that the worker will be unable to move due to a fall, injury, slip, getting stuck, etc. (step S5-11).The server control unit 34 then proceeds to step S6. On the other hand, if the answer is No in step S5-10, the server control unit 34 skips step S5-11 and proceeds to step S6.

[0060] The graph information GI and warning message information WI thus generated are transmitted to the management terminal 6 in step S6, and are displayed as a graph GR and a warning message WM on the management terminal display unit 44 in step S7. Managers can monitor workers by viewing the graph GR and the warning message WM. For example, if a manager sees a warning message WM indicating a possible heatstroke, the manager can contact the worker and urge them to take a break, replenish with fluids, or have a nearby worker or manager check on the worker. Furthermore, if a manager sees a warning message WM indicating a possible immobility, the manager can contact the worker and ask whether they have experienced a fall, injury, slip, get stuck, become ill, or have a nearby worker or manager check on the worker. Furthermore, the manager can grasp the worker's risk of heatstroke by viewing the marker on the graph GR related to the location information PI. The above-mentioned contact with the worker may be made via a mobile phone separately carried by the worker, or via at least one of the above-mentioned communication unit, text information communication unit, and alarm unit that the mobile terminal 2 may be equipped with. For example, if the mobile terminal 2 has a lamp-related alarm unit, the manager inputs, via the management terminal input unit 42, a command to issue a warning to the mobile terminal 2 that has issued the warning message WM regarding the possibility of heatstroke. Upon receiving this input, the management terminal control unit 48 transmits a warning information notification command to the corresponding mobile terminal 2 via the Internet IN. Upon receiving the warning information notification command via the mobile terminal communication unit 20, the mobile terminal control unit 24 turns on the lamp in a predetermined manner. The worker carrying the mobile terminal 2 can recognize the increased risk of heatstroke by receiving the warning information, i.e., the lamp being lit. The transmission of the warning information notification command may be performed via the server 4.

[0061] Note that the warning condition for the possibility of immobility may not take into account the first element related to the acceleration displacement, and may only take into account the second element related to the continuation of the position information PI being within a predetermined range for a specific period of time or more. That is, the server control unit 34 may determine that the warning condition for the possibility of immobility is satisfied when the state in which the position information PI is within a predetermined range continues for a specific period of time or more. Furthermore, warning message information WI regarding the possibility of sudden acceleration may be generated based on the satisfaction of a warning condition including only the first element related to acceleration displacement. That is, when the absolute value of the acceleration displacement indicated by the acceleration information AI exceeds a predetermined value, the server control unit 34 may determine that the warning condition regarding the possibility of sudden acceleration is satisfied and generate warning message information WI regarding the possibility of sudden acceleration. Furthermore, if the location information PI indicates that the location is outside a specific range at a predetermined time or within a predetermined period of time including that time, the server control unit 34 may generate a warning message WI regarding the worker's whereabouts being unknown, assuming that the warning condition regarding the worker's whereabouts being unknown is satisfied. For example, if the location information PI indicates that the location is outside a specific range including the office at a time determined by the organization to which the worker belongs or within a predetermined period of time including that time, the server control unit 34 may generate a warning message WI regarding the worker's whereabouts being unknown, assuming that the worker has not returned. By visually checking the warning message WM regarding the worker's whereabouts being unknown on the management terminal display unit 44 based on the warning message WI regarding the worker's whereabouts being unknown, the manager can understand that the worker is not where he or she should be at the predetermined time and can take action, such as contacting the worker, nearby workers, and nearby managers.

[0062] The above-described monitoring system 1 is a system for monitoring workers as persons under management, and includes a server 4 as a computer. The server 4 has a server communication unit 32 and a server control unit 34. The server communication unit 32 is capable of receiving temperature information TI indicating the temperature around the worker and humidity information HI indicating the humidity around the worker. The server control unit 34 calculates a heat index WG, which is a function of the temperature and humidity, from the temperature information TI and the humidity information HI. When the server control unit 34 determines that a predetermined condition related to the heat index WG is satisfied, it generates warning message information WI, which is information related to the warning message WM, and which indicates the possibility of heat stroke. Therefore, the manager watching over the workers can take appropriate measures such as displaying a warning message WM about the possibility of heat stroke based on the warning message information WI. Therefore, a monitoring system 1 that requires less effort from the manager is provided.

[0063] The server communication unit 32 can also receive weight information WE indicating the weight of the worker and exercise intensity information MT indicating the exercise intensity of the work. The server control unit 34 calculates the worker's metabolic heat determination reference values ​​RAL, REL from the weight information WE and the exercise intensity information MT. The server control unit 34 determines that a predetermined condition related to the heat index WG is met when the heat index WG remains equal to or greater than the metabolic heat determination reference values ​​RAL, REL for a predetermined period of time or longer. This allows the server 4 to generate more accurate warning message information WI regarding the possibility of heatstroke. Furthermore, the server communication unit 32 can receive heat acclimation information HA, which indicates the worker's heat acclimation status. The server control unit 34 calculates the metabolic heat determination reference value RAL before heat acclimation or the metabolic heat determination reference value REL after heat acclimation based on the heat acclimation information HA. This improves the accuracy of determining warning conditions related to the possibility of heat stroke, reflecting heat acclimation. This provides a monitoring system 1 that effectively reflects heat acclimation in worker monitoring and can better balance personnel allocation and management. Furthermore, the calculation of the metabolic heat determination reference values ​​RAL and REL includes the product of the weight information WE and the exercise intensity information MT. Therefore, the amount of calculation can be reduced while maintaining sufficient accuracy in determining whether a warning condition related to the possibility of heatstroke is met.

[0064] Furthermore, the monitoring system 1 includes a portable terminal 2 that can be carried by the worker. The portable terminal 2 includes a temperature acquisition unit 14 that acquires temperature information TI and a humidity acquisition unit 16 that acquires humidity information HI. Therefore, the temperature information TI and humidity information HI, which are necessary for determining whether a warning condition related to the possibility of heatstroke is met, can be more easily obtained by the portable terminal 2. The temperature acquisition unit 14 acquires the temperature information TI in a dry manner. This allows the temperature information TI to be obtained more easily than in a wet manner or using a black ball, while still ensuring sufficient accuracy in determining whether a warning condition related to the possibility of heatstroke has occurred.

[0065] Furthermore, the monitoring system 1 is equipped with a management terminal 6. The management terminal 6 has a management terminal display unit 44 that can be viewed by the manager who monitors the workers, and a management terminal communication unit 46. The server communication unit 32 transmits warning message information WI to the management terminal 6. When the management terminal 6 receives the warning message information WI at the management terminal communication unit 46, it displays a warning message WM related to the warning message information WI regarding the possibility of heatstroke on the management terminal display unit 44. Therefore, the warning message WM regarding the possibility of heatstroke can be displayed through simple processing and is easily recognized by the manager. Furthermore, processing of the management terminals 6 provided in multiple offices is performed collectively by the server 4. The heat index WG can be obtained by increasing the value of the simple indoor WBGT. Therefore, the heat index WG can be obtained more easily while still maintaining sufficient accuracy in determining the warning conditions related to the possibility of heatstroke.

[0066] On the other hand, the monitoring system 1 is a system that monitors workers as persons under management, and includes a server 4 as a computer. The server 4 has a server communication unit 32 and a server control unit 34. The server communication unit 32 is capable of receiving at least one of position information PI indicating the position of the worker and position information relationship information RI, which is information related to the position information PI, and acceleration information AI indicating the acceleration of the worker. When the server control unit 34 determines that a predetermined condition related to at least one of the position information PI and the acceleration information AI is satisfied, it generates warning message information WI, which is information related to a warning message WM, indicating the possibility that the worker may be unable to move. Therefore, the manager watching over the worker can take action in response to the display of the warning message WM about the possibility of being unable to move based on the warning message information WI, etc. Therefore, a watching system 1 that requires less effort from the manager is provided.

[0067] Furthermore, the server control unit 34 determines that a predetermined condition related to at least one of the position information PI and the acceleration information AI is satisfied when the position related to the position information PI remains within a predetermined range for a specific period of time from when the absolute value of the acceleration displacement related to the acceleration information AI exceeds a predetermined value until a predetermined period of time has elapsed. Thus, the server 4 can generate more accurate warning message information WI related to the possibility of immobility.

[0068] Furthermore, the monitoring system 1 includes a portable terminal 2 that can be carried by the worker. The portable terminal 2 includes a position information acquisition unit 12 that acquires at least one of position information PI and position information relationship information RI, which is information related to the position information PI, and an acceleration acquisition unit 18 that acquires acceleration information AI. Therefore, the position information PI, position information relationship information RI, and acceleration information AI, which are necessary for determining whether a warning condition related to the possibility of immobility exists, can be more easily obtained by the portable terminal 2.

[0069] Furthermore, the monitoring system 1 is equipped with a management terminal 6. The management terminal 6 has a management terminal display unit 44 that can be seen by the manager who monitors the workers, and a management terminal communication unit 46. The server communication unit 32 transmits warning message information WI to the management terminal 6. When the management terminal communication unit 46 receives the warning message information WI, the management terminal 6 displays a warning message WM related to the warning message information WI regarding the possibility of being unable to move on the management terminal display unit 44. Therefore, the warning message WM regarding the possibility of being unable to move can be displayed by simple processing and is easily recognized by the manager. Furthermore, processing of the management terminals 6 provided in each of multiple offices is performed collectively by the server 4.

[0070] 3B, the processing of the worker information OI, including the generation of the display information DI, in the server 4 may be performed in each mobile terminal 2 (edge ​​processing type). That is, steps S2, S4-4, S5, and S6 may be performed in the mobile terminal 2. In this case, compared to processing on the server 4 described above (cloud processing type), the processing volume on each mobile terminal 2 increases, and the mobile terminal 2 becomes larger to accommodate that processing volume, but the worker information OI remains on the mobile terminal 2, and the amount of communication between the mobile terminal 2 and the server 4 is reduced. The display information DI may or may not be stored in the server storage unit 30. Furthermore, the mobile terminal 2 may directly transmit the display information DI to the management terminal 6. In this case, the server 4 can be omitted. [Explanation of symbols]
