In addition to the utility pole 30 shown in the figure, location information of other power transmission / distribution facilities such as a steel tower 40, a transformer, and a switch may be registered. Moreover, you may provide the flag which identifies terminal ID etc. which correspond to the place where the disaster or the accident of the power transmission / distribution facility generate | occur | produced by the information received from the monitoring control apparatus 100, the information notified from the Meteorological Agency, etc.

  In the above case, the location identification device 200 acquires the employee ID and the terminal ID from the communication terminal 15 via the slave station 20 and the like, and registers various types of information shown in FIG. Specifically, a terminal ID, a safety confirmation flag, and an emergency countermeasure response availability flag are registered in association with each employee ID. Note that the safety confirmation flag is assigned a “○” mark when the terminal ID is registered in association with the employee ID (when there is a contact from the corresponding employee), and the terminal is associated with the employee ID. When the ID is not registered (when there is no contact from the corresponding employee), the flag is assigned with an “x” mark. In addition, the emergency countermeasure response availability flag is registered with the location information (in the case of the present embodiment, the area of the terminal ID (n1)) where the disaster or the transmission / distribution facility accident has been acquired in advance. In contrast to the terminal ID, the flag is used to identify the location where the disaster or accident occurred and the employees located therearound, that is, the employees who can request emergency measures. In addition, in the case of employees who can request emergency countermeasures, “○” mark is given, and in the case of employees who cannot request emergency countermeasures (when located in a place far away from where the disaster or accident occurred) “X” mark is given.

  Further, the location identifying device 200 is based on the registration contents of the location confirmation database 207 shown in FIG. 9 and the registration contents of the employee information database 205 shown in FIG. 208 is generated. Specifically, in response to the identification of employees who can request emergency countermeasures from the location confirmation database 207, it is possible to build a team structure of inspection teams and recovery teams as shown in FIG.
