BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a safety confirmation system according to an embodiment of the present invention will be described with reference to the drawings.

  This system is a system for confirming safety when a large-scale disaster such as an earthquake occurs, for example. As a preferred embodiment of this system, for example, a company or an organization can be used for confirming the safety of an employee or an employee, and this case will be described as an example in the following description.

  The system includes a safety confirmation server 1 and a mobile phone 3 carried by each employee 2 as shown in FIG. The mobile phone 3 may be replaced with a portable information communication device other than a mobile phone such as a PDA (Personal Digital Assistance). The safety confirmation server 1 and the mobile phone 3 are connected to each other via the mobile phone network 4.

  The safety confirmation server 1 is constituted by, for example, a general-purpose computer system, and individual components or functions in the safety confirmation server 1 described below are realized by executing a computer program, for example.

  The safety confirmation server 1 has, as its internal functions, a disaster information collection unit 101, a confirmation area identification unit 102, a location information collection unit 103, a target selection unit 104, a safety information collection unit 105, an employee database 106, A disaster information database 107, a safety database 108, a map database 109 storing map information, a safety confirmation unit 110, and a position history database 111 storing the displacement of the position of each mobile phone are provided.

  The disaster information collection unit 101 collects various information about the disaster when the disaster occurs and stores it in the disaster information database 107. The disaster information may be collected from, for example, an external system (not shown), or may be input from the input device 5 by an operator of the present system.

  For example, as shown in FIG. 2, the disaster information database 107 includes, as data items, a disaster type 171, a disaster occurrence date and time 172, a confirmation area 173 that requires confirmation of a disaster situation, and a disaster situation 174.

  The disaster type 171 indicates a disaster type such as an earthquake or a fire.

  The confirmation area 173 indicates an area that is highly likely to have been damaged by a disaster and that requires confirmation of employee safety. The confirmation area 173 may be received by the operator of the present system or may be specified by the confirmation area specifying unit 102 described below.

  The disaster situation 174 indicates information regarding the disaster that has occurred. For example, if it is an earthquake, it includes the epicenter, magnitude, seismic intensity of each place, the possibility of a tsunami, and its area, and if it is a fire, it includes the location where the fire occurred, weather, humidity, wind direction, wind force, and the like.

  Referring again to FIG. 1, the confirmation area specifying unit 102 specifies a confirmation area that needs to be confirmed based on the disaster situation stored in the disaster information database 107. Information indicating the identified confirmation area is stored in the disaster information database 107. For example, in the case of a fire, the confirmation area may be an area having a radius within a predetermined range from the place where the fire occurred. In that case, wind direction and humidity can be taken into consideration. Further, in the case of an earthquake, the prefecture to which the epicenter belongs and the prefectures adjacent thereto may be specified, or the seismic center, magnitude, seismic intensity information of each place, and the like may be specified.

  The position information collection unit 103 collects position information indicating the position where the mobile phone 3 is present. For example, the location information collection unit 103 refers to the employee database 106 and notifies the mobile phones 3 of all employees to transmit location information indicating the current location. This may use either a telephone or electronic mail function. The location information collection unit 103 receives the location information sent from each mobile phone 3 and stores it in the safety database 108.

  Here, the employee database 106 stores attribute information of all employees. For example, as shown in FIG. 3, the employee database 106 includes, as data items, an employee ID 161, a name 162, an affiliation 163, a mobile phone number 164, a mobile phone e-mail address 165, and an administrator phone number. 166 and an administrator email address 167.

  The employee ID 161 is employee identification information. The phone number and e-mail address 164, 165 of the mobile phone are the phone number and e-mail address of the mobile phone carried by each employee. The administrator's telephone number and e-mail address 166, 167 are the telephone number and e-mail address of the mobile phone carried by the administrator who manages each employee.

  The safety database 108 stores information for confirming the safety of each employee. For example, as shown in FIG. 4, the safety database 108 includes employee IDs 181, current position information 182, a confirmation area flag 183, and safety information 184 as data items.

  The current position information 182 is information indicating the current position of the mobile phone 3 carried by each employee. The confirmation area flag 183 is a flag indicating whether each employee's mobile phone is present in the confirmation area. The safety information 184 is information regarding the safety of each employee. The safety information 184 stores, for example, safety information transmitted from each mobile phone 3 as described later.

  Referring again to FIG. 1, as another mode of collecting position information, the position information collecting unit 103 may receive position information sent from the mobile phone 3 regularly or irregularly. In this case, the received location information is stored in the location history database 111 that stores the history of location information for each mobile phone.

  The target selection unit 104 identifies the mobile phone 3 existing in the confirmation area, and sets the employee 2 who uses the mobile phone 3 as a safety confirmation target. For example, the target selection unit 104 refers to the safety database 106 to acquire the current position of the mobile phone carried by each employee, and refers to the disaster information database 107 to acquire the confirmation area. Then, it is determined whether the cellular phone 3 of each employee 2 exists in the confirmation area. Here, the object selection unit 104 sets the in-area flag 183 of the safety database 108 to “in area” for the employee 2 in the confirmation area.

  The safety information collection unit 105 sends a safety confirmation notification to the mobile phone 3 of the employee 2 in the confirmation area, and collects safety information of the employee in the confirmation area. For example, the safety information collection unit 105 refers to the in-area flag 183 of the safety database 108, identifies the employee ID of the employee who is “in area”, and obtains the telephone number of the employee's mobile phone 3 from the employee database 106. Acquire and send a safety confirmation notification. The safety information collection unit 105 receives the safety information input in response to the safety confirmation notification transmitted from each mobile phone 3 and stores it in the safety database 108.

  The safety confirmation unit 110 confirms whether the safety confirmation of all employees has been completed. For example, the safety database 18 is referred to, an employee whose safety has not been confirmed is extracted, and a screen for prompting safety confirmation is displayed on the display device 6 or the manager of the employee is notified. These detailed processes will be described later.

  When the history of position information is accumulated in the position history database 111, the safety confirmation unit 110 refers to the position history database 111 and the map database 109 to display the trajectory of each employee on the map. May be. The employee whose trajectory is displayed may be an employee whose safety has not been confirmed, or an employee designated by the operator. Thereby, the location of the employee in the vicinity of the time when the disaster occurred can be known.

  Next, the mobile phone 3 will be described. The mobile phone 3 carried by each employee 2 includes a display unit 31 such as a liquid crystal panel. The mobile phone 3 has, for example, an electronic mail function, an Internet access function, and a function for specifying a position using a GPS (Global Positioning System) in addition to a normal call function. The cellular phone 3 specifies the current position (for example, latitude and longitude) of its own device using this GPS function, and notifies the safety confirmation server 1 of the position information.

  When the mobile phone 3 receives the notification of the position information transmission request from the server 1, it may return the current position information to the server 1. In order to realize this function, the mobile phone 3 activates a so-called standby application and receives an incoming call from a predetermined telephone number indicating the safety confirmation server 1 or a mail from a predetermined e-mail address. You may make it reply.

  Further, the mobile phone 3 may transmit the position information of its own device regularly or irregularly even if there is no request from the safety confirmation server 1.

  Further, the mobile phone 3 receives a safety confirmation notification from the safety confirmation server 1. At this time, a safety application input screen is displayed on the display unit 31 by using a standby application that is activated upon receipt of an incoming call or an e-mail, and receives an input from an employee.

  An example of the safety information input screen 100 is shown in FIG. The input screen 100 may be acquired from a predetermined URL, for example. Each employee inputs safety information on the input screen 100. The safety information input on the input screen 100 is transmitted to the safety confirmation server 1 when the input completion button 110 is pressed. After the safety information is transmitted, the mobile phone 3 returns to the standby state.

  In the safety confirmation system having the above-described configuration, the procedure of safety information collection processing at the time of disaster will be described with reference to the flowchart of FIG.

  First, when a disaster occurs, the disaster information collection unit 101 collects disaster information and stores it in the disaster information database 107 (S11). When the confirmation area identifying unit 102 identifies a confirmation area that needs to be confirmed based on the disaster information or acquired from the outside, the location information collecting unit 103 notifies all employees of the mobile phones 3 of the occurrence of the disaster. (S12).

  Each mobile phone 3 that has received this notification confirms its current location (S21). At this time, for example, if the mobile phone has a position confirmation function using GPS, the current position is specified using this function. Then, the current position information is transmitted to the safety confirmation server 1 (S22).

  When the location information collection unit 103 acquires the current location information from each mobile phone 3, the safety confirmation server 1 stores this in the safety database 108. Then, the target selection unit 104 refers to the disaster information database 107 and the safety database 108 to determine whether each mobile phone 3 is within the confirmation area (S13). Mobile phones outside the confirmation area are not subject to safety confirmation (S13: No). The safety information collection unit 105 transmits a safety confirmation notification to the mobile phone 3 in the confirmation area (S14).

  In the mobile phone 3 that has received the safety confirmation notification, the safety information input screen (see FIG. 5) is displayed on the display unit 31, and predetermined safety information is input (S23). The safety information input here is transmitted to the safety confirmation server 1 and stored in the safety database 108.

  As a result, it is possible to collect the safety information of employees in the area where the disaster is expected when a disaster occurs. Note that the location information of the mobile phone may be obtained by a method other than using the GPS function of each mobile phone. For example, a range specified from the position of the base station in which each mobile phone is accommodated may be acquired as position information.

  The employee's safety can be confirmed by referring to the safety information database 108 storing the safety information acquired as described above. For example, the administrator can check the safety information of the subordinate employees managed by him / her by referring to the safety information stored in the safety information database 108. Moreover, you may make it the safety confirmation server 1 notify the safety information of the employee of a subordinate to an administrator. Further, the employee's family can also access the safety information database 108 and confirm the safety. When an administrator or family member accesses the safety information database 108, access to information other than necessary information may be restricted.

  Through the above-described processing, the location information of the mobile phone and the safety information of employees in the confirmation area can be collected. However, there are cases where location information of mobile phones cannot be collected and safety information cannot be collected due to various reasons. At this time, the above-described processing may be retried at a predetermined time interval to try to collect safety information. Nevertheless, when the safety information cannot be collected, the system performs processing such as the flowchart shown in FIG.

  First, the safety confirmation unit 110 refers to the safety database 108 and extracts employees for which the current position 182 is not set (S31). Furthermore, the safety confirmation unit 110 extracts employees whose in-area flag 183 is “in area” and for which safety information 184 is not set (S32).

  Then, a predetermined screen is displayed on the display device 6 in order to notify the presence of the employee whose safety has not been extracted extracted in steps S21 and S22 (S33). For example, the safety confirmation unit 110 acquires attribute information of employees whose safety has not been confirmed from the employee database 16 and displays the list screen on the display device 6. In addition, for employees who have the position information 182 but not the safety information 184, the safety confirmation unit 110 refers to the map database 109 and displays its position on the map as shown in FIG. X) may be displayed.

  In addition, the safety confirmation unit 110 notifies the manager of the employee whose safety has not been confirmed (S34). At this time, the safety confirmation unit 110 acquires the telephone number 166 or e-mail address 167 of the manager of the employee whose safety has not been confirmed from the employee database 16 and notifies it by telephone or e-mail.

  Here, the employee extracted in step S32, that is, the employee for whom safety information has not been input even though it is confirmed that he / she is in the confirmation area, is very likely to be damaged. For this reason, this employee may be highlighted or the priority of notification to the administrator may be increased.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to those embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.
