Description

  The present invention relates to an action support system and a portable terminal that support, for example, the actions of workers in disaster activities.

  For example, when an earthquake or flood damage occurs in a snowy area in winter, the victims and disaster prevention personnel engaged in disaster response are exposed to a cold environment. The cold environment has various effects on the human body and mind. In particular, the impact on extremity activity and cognitive ability is very important because it is directly related to personal safety for disaster victims and disaster prevention personnel during disaster response activities. The physiological burden of the cold environment on the human body is called cold stress. For example, if an earthquake, tsunami, or storm surge occurs in Hokkaido during the snowy season, you have to work outdoors to respond to the disaster, or if you are in a situation where you are waiting for rescue indoors where the heating equipment does not function Moreover, disaster prevention personnel and victims are exposed to this cold stress.

  On the other hand, various environmental monitoring systems that measure information related to the natural environment such as air and water quality over a wide area and collect and use the measurement results at the center have been proposed (see, for example, Patent Document 1 or Patent Document 2). ). If measurement information obtained by such an environmental monitoring system is used, more efficient disaster relief activities can be expected in consideration of the state of the natural environment such as weather and temperature.

Japanese Patent Laid-Open No. 2004-155908

  However, all of the conventional environmental monitoring systems measure the natural environment over a wide area. For this reason, even if the measurement information is used for disaster response, it is limited to disaster relief activities for each wide area, for example, measures to reduce the activity efficiency due to the cold stress of each disaster victim or person in charge of disaster prevention, and measures to avoid the risk of continuing activities It is difficult to use it.

  The present invention has been made to solve such a problem, and the object of the present invention is to make it possible to predict and report environmental indicators related to the activities of disaster victims and disaster prevention personnel on an individual basis. It is providing the action support system and portable terminal which can avoid the fall of activity efficiency and activity continuation risk for every victim or disaster prevention person in advance.

  In general, it has occurred as a treatment to deal with changes in the natural environment of the person that individuals who act in a local environment encounter, especially dangerous events that may cause health damage or abnormalities in the living body It is important to detect in advance the events that could trigger these, and take preventive measures at the risk stage, rather than the subsequent measures to detect later dangerous events or the biotransformation itself. This is because, at the stage of preventive measures, simple countermeasures that can be carried out by the person himself / herself are often necessary, but once a dangerous event has occurred, a prompt and advanced response at a level that will compete for a moment. This is because there are many cases in which life-saving measures by a third party are necessary because self-help and self-supporting measures are no longer possible.

The first aspect of the present invention has been made in consideration of the above points, and is connected to a sensor for detecting a state quantity of an event occurring in the living body or the body due to the surrounding environment, and further information In an action support system comprising a portable terminal provided with the input means and the presenting means, and a management device capable of information communication with the portable terminal via a communication network,

On the other hand, the management device receives the information indicating the detection information and the activity state transmitted from the mobile terminal via the communication network, and based on the received detection information and the information indicating the activity state. A local environmental index related to the activity of the portable terminal holder is calculated. Then, the information representing the calculated local environment index is transmitted to the portable terminal which is the transmission source of the detection information and the information representing the activity state via the communication network, and is presented to the portable terminal holder. It is a thing.

  On the other hand, according to a second aspect of the present invention, in the mobile terminal, the detection information of the state quantity of the event that occurs in the living body or the body due to the surrounding environment is acquired from the sensor, and the activity state of the mobile terminal owner is determined. It is configured to accept input of information to be expressed, calculate a local environmental index related to the activity of the mobile terminal holder based on the acquired detection information and information indicating the activity state, and present it to the owner It is.

  Therefore, according to the first and second aspects of the present invention, on the basis of the state quantity of an event occurring in the living body or the body detected by the sensor for each portable terminal holder and the activity state of the owner, A local environmental index related to the owner's activity is calculated and presented to the owner. As a result, victims and people involved in disaster prevention can take appropriate measures against changes in the natural environment they encounter, especially cold stresses that can cause health damage. Therefore, it becomes possible to avoid the decrease in activity efficiency and the risk of continuation of activities for each disaster victim or person in charge of disaster prevention.

The first aspect of the present invention is characterized by comprising the following components.
In the first configuration, input format data in which an input item of information indicating an activity state of the portable terminal holder is transmitted from the management device to the portable terminal via the communication network, and the management is performed in the portable terminal.

Then, based on the calculated clothing heat retaining power and the maximum recommended stay time, a notification message indicating a condition for continuing the activity and a time limit thereof is generated.
If it does in this way, it will become possible to show an individual cold index as an activity index to a victim and a person in charge of disaster prevention.

According to a third configuration, in the management device, wide-area weather information including an activity area of the portable terminal holder is acquired from a weather information server, and a local environment index is obtained based on the acquired weather information and current time information. The correction process is further performed.
In this way, not only the local environment information of disaster victims and disaster prevention personnel themselves, but also a wide range of weather information, that is, taking into account expected changes in weather, temperature, etc. It is possible to guess and present more accurately.

  In short, according to the present invention, it becomes possible to predict and notify the occurrence of a dangerous event or biotransformation of a disaster victim or disaster prevention person in a situation where a disaster has occurred. It is possible to provide an action support system and a portable terminal capable of avoiding a decrease in activity efficiency for each person in charge and an activity continuation risk in advance.

  The database 16 includes a plurality of worker management data for managing addresses and the like of portable terminals MSa possessed by workers such as disaster victims and disaster prevention personnel, and a plurality of activities indicating the activity state to the owner of the portable terminal MSa. An electronic document file for inputting these items and information representing an activity index calculated for each worker by an activity index calculation program described later are stored.

  The program memory 13 stores a page generation / distribution program 131, a worker management program 132, and an activity index calculation program 133 as application programs necessary for carrying out the present invention. The data memory 14 is used for temporarily storing data generated during the execution of each program, data transmitted / received by the communication I / F 15, and the like.

  The page generation / distribution program 131 causes the CPU 11 to execute the following processing. That is, input format data for allowing the owner of the portable terminal MSa to input information indicating the activity state by item is HTML (HyperText Markup Language) or XHTML (eXtensible HyperText Markup Language) (hereinafter, both are collectively HTML). (Denoted as (XHTML)) is generated, and the generated electronic document file is stored in the database 16. When the access request transmitted from the web browser of the mobile terminal MSa is received by the communication I / F 15, the electronic document file in the input format is read from the database 16, and the communication I / O is sent to the requesting mobile terminal MSa. / F15 to deliver. At the same time, http response data input to the electronic document file by the Web browser of the portable terminal MSa is received via the communication I / F 15.

  The worker management program 132 manages information indicating the activity index calculated for each worker by the activity index calculation program 133 by managing the address and the like of the mobile terminal MSa possessed by the worker. The CPU 11 is caused to execute a process of storing in the database 16 in association with the identification information.

  The activity index calculation program 133 calculates the activity index of the worker based on the information indicating the activity state of the worker and the measurement data of the sensor sent from the web browser of the mobile terminal MSa, and further calculates the calculation The CPU 11 is caused to execute processing for generating a warning message based on the result.

On the other hand, the mobile terminal MSa is composed of, for example, a mobile phone or a PDA (Personal Digital Assistant) and is configured as follows. FIG. 3 is a block diagram showing the hardware configuration.
That is, the mobile terminal MSa includes a mobile terminal body 20 and an air temperature sensor 26, a humidity sensor 27, and an anemometer 28 connected to the mobile terminal body 20 via a serial interface 29. The temperature sensor 26, the humidity sensor 27, and the anemometer 28 measure the temperature, humidity, and wind speed around the portable terminal MSa, respectively, and output the measurement data.

  The mobile terminal body 20 includes an information processing unit 21, a communication interface 22, an information storage unit 23, a display unit 24 including, for example, a liquid crystal display, and an input interface 25 including a dial keypad and a function key group. I have. The communication interface 22 transmits and receives information data wirelessly with the management server SVa under the control of the information processing unit 21. The information storage unit 23 stores a URL (Uniform Resource Locator) of the management server SVa together with telephone directory data arbitrarily created by the owner. The information storage unit 23 stores measurement data obtained by the sensors 26, 27, and 28, information representing the activity state of the owner input by the owner, and information representing an activity index sent from the management server SVa. Is also used.

  The information processing unit 21 includes a CPU such as a microprocessor and a program memory. In the program memory, as an application program necessary for carrying out the present invention, a sensor information processing program 211 for fetching each measurement data of the sensors 26, 27, 28 via the serial interface 29, a Web browser 212, and a management A program for displaying information representing the activity index sent from the server SVa on the display unit 24 is stored.

  Among them, the Web browser accesses the management server SVa in response to an input of an access request through the input interface 25, receives an electronic document file downloaded from the management server SVa in response to this access, and receives the input format data. It is displayed on the display unit 24. Then, according to the displayed input format, a process of transmitting information indicating the activity state input by the holder via the input interface 25 and each measurement data captured from the sensors 26, 27, and 28 to the management server SVa. The CPU is executed.

Next, operations of the management server SVa and the mobile terminal MSa configured as described above will be described. FIG. 4 is a flowchart showing the processing procedure and processing contents.
It is assumed that the owner (worker) of the mobile terminal MSa activates the Web browser 212 and designates and inputs a URL corresponding to the required page when starting the restoration work. Then, the Web browser 212 transmits an input electronic document file download request to the management server SVa by an HTTP (HyperText Transfer Protocol) request.

  On the other hand, when an HTTP request arrives from the mobile terminal MSa, the management server SVa activates the page generation / distribution program 311 in step S41. Then, an electronic document file in which input format data is described in HTML (XHTML) code is read from the database 16 or the data memory 14, and the read electronic document file is downloaded toward the requesting mobile terminal MSa.

  When the electronic document file is downloaded, the web browser 212 of the portable terminal MSa displays the electronic document file on the display unit 24. At this time, in the electronic document file, a sensor information processing program 211 that operates on the web browser 212 of the mobile terminal MSa, together with code information for generating and displaying a web page on the web browser 212, is, for example, Java (registered trademark). ) It is written in Script. Therefore, for example, as shown in FIG. 6, a selection button B <b> 1 for inputting a plurality of items representing an active state and a button B <b> 2 for starting sensor measurement are displayed on the display unit 24 of the mobile terminal MSa. .

  In this state, the worker first selects and inputs his / her own activity state by item by sequentially pressing the selection button B1 displayed in the input format. In step S42, the Web browser 212 takes in information on each input item selected by the selection button B1. Thus, the amount of clothes, the walking speed, and the exercise form are selected and input, respectively.

  Next, the worker sequentially presses the sensor measurement start button B2. Then, in step S43, the sensor information processing program 211 described by Java (registered trademark) Script is activated. As a result, in step S44, the measurement data of the temperature, humidity, and wind speed respectively measured by the temperature sensor 26, the humidity sensor 27, and the wind speed sensor 28 are taken in via the serial interface 29.

  When the acquisition of each measurement data is completed, the Web browser 212, in step S45, the information indicating the acquired activity state of the worker, that is, the information indicating the amount of clothes, the walking speed, and the exercise form, the sensor 26, Each measurement data of temperature, humidity and wind speed taken in from 27 and 28 is transmitted to the management server SVa as an http response.

  On the other hand, when the management server SVa receives the information representing the activity state of the worker and the measurement data of each sensor from the portable terminal MSa, the activity index calculation program 133 is activated in step S46, and the received information Based on the above, an activity index (here, a cold index) of the worker is calculated.

FIG. 5 is a flowchart showing the cold index calculation processing procedure and processing contents. In the flowchart, steps S51 and S52 are steps executed in the mobile terminal MSa.
One index related to cold is Wind Chill Temperature (WCT). This represents the coolness of the air temperature, taking into account the effect of the wind speed, in terms of the air temperature in a calm state (wind speed 4.2km / h).
WCT = 13.12 + 0.6215 × Ta−11.37 × V ^0.16 + 0.3965 × Ta × V ^0.16 ……… (1)
Here, WCT: [° C.], Ta: Air temperature [° C.], V: Wind speed [km / h] at a ground height of 10 m. WCT does not consider the effects of heat from the sun. In addition, it is the equivalent temperature in walking state at 3mph (about 1.34m / s).

Examples of indicators based on various conditions of the cold environment and the heat balance of the human body include IREQ (required clothing insulation) and DLE (duration limited exposure) defined in ISO 11079 (2007). IREQ is defined as the warming power of clothing necessary to keep body temperature and skin temperature at an acceptable level in activities in cold environments, and heat production and heat radiation to the environment (the environment brings to the body) It is calculated by the balance of (cooling power). The basic definition formula of IREQ is as follows.
IREQ = (Tsk−Tcl) / R + C (2)
However, the following ranges are recommended as environmental conditions. Ta ≦ 10 ° C., 0.4 m / s ≦ Va ≦ 18 m / s, Icl> 0.078 m ² K / W (0.5 clo). Where IREQ: [m ² K / W], Tsk: average skin temperature [° C], Tcl: clothing surface temperature [° C], R: radiant heat exchange [W / m ² ], C: convective heat transfer [W / m ² ], Va: relative wind speed [m / s], Icl: thermal resistance of clothes [m ² K / W].
When IREQ is expressed as a clo value, it is converted according to the following formula.
1clo = 0.155 m ² K / W.

IREQ has two levels, IREQ neutral and IREQ min. IREQ neutral is defined as the garment heat retention necessary to maintain a thermal neutral state where the average body temperature is maintained at a normal level. IREQ min is defined as the minimum garment heat retention necessary to maintain the average body temperature slightly below normal. If the thermal insulation of the garment is less than the calculated IREQ, it is considered that there is a risk of progressive body cooling and the stay (exposure) time in the cold environment must be limited to prevent the cooling from proceeding There is. DLE (Dlim) is defined as the recommended maximum stay time. The basic definition of Dlim is as follows:
Dlim = Qlim / S ……… (3)
Here, Dlim: [h], Qlim: heat loss limit value [kJ / m ² ], and S: heat storage amount [W / m ² ].
The above calculation of IREQ, comparison of IREQ with Icl, R, and calculation of Dlim are performed in steps S54 to S58 in the flowchart shown in FIG.

  For the evaluation method of the cold environment described above, see International Organization for Standardization (2007), “ISO 11079 Ergonomics of the thermal environment-Determination and interpretation of cold stress when using required clothing insulation (IREQ) and local cooling effects”. It is described in detail.

  When the activity index (cold index) in the cold environment, that is, the required clothing amount (IREQ min) and the maximum recommended stay time (DLE min) are calculated, the management server SVa, in step S47, calculates the calculated required clothing amount ( IREQ min) and warning message for workers based on the maximum recommended stay time (DLE min). As the warning message, for example, an easily understandable message such as “allowable continuous work time outdoors: 35 minutes” is used.

  Then, the generated warning message is transmitted from the communication I / F 15 to the mobile terminal MSa. As a transmission method, a method of displaying on the web browser 212 of the mobile terminal MSa may be used, or an e-mail may be used. Note that the calculated necessary amount of clothes (IREQ min) and maximum recommended stay time (DLE min) may be transmitted together with the warning message.

  In step S48, the management server SVa obtains the calculated required clothing amount (IREQ min) and the maximum recommended stay time (DLE min) from the telephone number of the portable terminal MSa or the worker who owns the portable terminal MSa. It is stored in the database 16 in association with unique information that can identify a worker such as an ID.

On the other hand, when the warning message is transmitted from the management server SVa and received via the communication interface 22, the information processing unit 21 of the portable terminal MSa displays the received warning message on the display unit in step S49. 24. In addition, when the necessary clothes amount (IREQ min) and the maximum recommended stay time (DLE min) are sent together with the warning message from the management server SVa, in addition to the warning message, the necessary clothes amount (IREQ min) and the maximum stay The recommended time (DLE min) may be displayed together.
Thus, a warning message based on the cold index of the individual worker who is the owner is displayed on the portable terminal MSa. FIG. 7 shows a specific example from the calculation of the cold index described above to the display of a warning message based on the calculation result.

  As described above, in the first embodiment, the information indicating the activity state of the worker who is input on the web browser 212 in the mobile terminal MSa, that is, the information indicating the amount of clothes, the walking speed, and the exercise form, and the sensor 26. , 27, 28, each measurement data of temperature, humidity and wind speed is transmitted as an http response to the management server SVa. In the management server SVa, the information indicating the activity state of the worker is sent from the mobile terminal MSa. In addition, an activity index (cold index) of the worker is calculated based on each measurement data of each sensor, and a warning message based on the calculation result is transmitted to the mobile terminal MSa for display.

  Therefore, it is possible for workers to take appropriate measures in advance for cold stresses that may cause their own health damage in a cold environment. It becomes possible to avoid the decrease in activity efficiency and the risk of continuing activities in advance.

  In the management server SVa, an electronic document file in which input format data is described in HTML (XHTML) is generated, transmitted to the mobile terminal MSa, displayed on the Web browser 212, and an activity state input on the input format is displayed. Information to be expressed and measurement data of each sensor 26, 27, 28 are transmitted as an http response to the management server SVa. Therefore, the holder of the portable terminal MSa can input necessary information quickly without omission.

When a measurement request for the surrounding environment is input through the input interface 25, the measurement data of the sensors 26, 27, and 28 are transmitted via the serial interface 29. The CPU of the information processing unit 21 executes the capturing process.

  The activity index calculation program 213 generates input format data and causes the display unit 24 to display the data. The activity index calculation program 213 captures information representing the activity state input on the input format via the input interface 25, and the captured activity state. The CPU 11 executes a process of calculating an activity index of the worker based on the information indicating the information and the measurement data of the sensors 26, 27, and 28 taken in by the sensor information processing program 211 and causing the display unit 24 to display the activity index. Let
