Next, the operation of the route search means 126 will be described in detail with reference to FIG.
First, a search request including the latitude and longitude of the current position of the worker, the target utility pole number, and weather information is received (S101). Then, the position number of the nearest utility pole is extracted from the equipment position DB 62 based on the received latitude and longitude of the current position (S102). Next, based on the utility pole number or address of the target utility pole, the position number of the nearest utility pole is extracted from the equipment position DB (S103). A route code, required time, distance, moving means, and map information are extracted from the route information table based on the location number of the utility pole closest to the current location and the location number of the destination utility pole (S104). Next, the required time extracted by referring to the required time correction table based on the received weather information is corrected (S105). Then, the route code, distance, moving means, map information extracted in step S104 and the required time corrected in step S105 are transmitted to the mobile personal computer 2 (S106).

  FIG. 9 is a required time correction table referred to in step S105. The required time extracted in step S104 is corrected by information such as weather and moving means transmitted from the mobile personal computer 2.

  In this figure, for example, when the weather is rainy or snowy and the railway is used as a moving means, this means that the required time is increased by 5% compared to a “sunny” day. The required time is corrected by the combination of the weather when the route search is executed and the moving means of the search route.

  The route search result transmitted from the transmission / reception unit 11 of the map information system 1 is received by the mobile personal computer 2 and displayed to workers from the current location to the target utility pole.

  FIG. 10 shows a route search screen after route search. In this figure, the location information of the current location and the location information of the destination are displayed, and information such as the moving means from the current location to the destination (electric pole), required time, distance, map information, and comments on the location on the route are displayed.
