And equipment data 4
No. 2 of the child data 43 on the right side of 2. Are compared, and the equipment data 41 is the key number of the child data 43. If it is larger than that, the equipment data 41 moves to the left side of the child data 43, and if smaller, moves to the child data on the right side of the child data 43. In the case of the example shown in FIG. Is child data 4
Key No. 3 Is smaller than the child data descent process 4
Due to D, the equipment data 41 moves to the child data 44 on the right side of the child data 43. Next, the key No. of the equipment data 41. And the key number of the child data 44. And are compared, equipment data 4
Key No. 1 Is the key number of the child data 44. Therefore, the child data descending process 4E moves to the child data on the left side of the child data 44, and moves to the child data 45 on the left side of the child data 44. Next, the key No. of the equipment data 41. And the key number of the child data 45. And the key No. of the equipment data 41 are compared. Is the key number of the child data 45. Therefore, the equipment data 41 is moved to the child data 46 on the right side of the child data 45 by the child data descending process 4F. Here, since the child data 46 is NULL, that is, empty data, the facility data 41 is input to the child data 46 as a tree. By the above operation, the additional data tree is input.

Key No. 1 Is read out and the key No. of connection 1 or connection 2 of the electric wire 52 is read. (Electric pole No.) is compared with the equipment tree. Key No. of the equipment data 61.
Is the key number of the equipment data 62 at the top of the tree. And the key No. of the equipment data 61. Is the key number of the equipment data 62. If it is larger, the equipment data 61 is the child data on the left side of the equipment data 62, and the key No. of the equipment data 61.
Is the key number of the equipment data 62. If it is smaller, the equipment data 61 moves to the child data on the right side of the equipment data 62. In FIG. 9, the key No. of the equipment data 61 is displayed. 105 is a key No. of the equipment data 62. Since it is smaller than 100, the child data descending process 6A moves to the child data 63 on the left side of the equipment data 62. Next, the key No. of the equipment data 61. And equipment data 63 key No. Is compared and the equipment data 6
Key No. 1 Is the key number of the equipment data 63. If it is larger, the equipment data 61 is the child data on the left side and the key No. of the equipment data 61. Is the key number of the equipment data 63. If it is smaller, the equipment data 61 moves to the child data on the right side. In FIG. 9, the key No. of the equipment data 61 is displayed. 100 is the key number of the child data 63. Since it is smaller than 110, the equipment data 61 moves to the child data 64 on the right side of the child data 63. Key No. of the child data 64. 105 is equipment data 61
Key No. Since it matches 105, the data of the child data 64 is read. The electric wire 52 is determined by the child data 64, and the electric pole 53 which is the other equipment connected to the electric wire 52 can be confirmed.
