First, the cable closest to the search start facility through which all upstream routes pass is specified (step S160), and it is determined whether or not there is an upstream route (step S161). If there is no upstream route, all searched routes are extracted as downstream routes (step S162).

On the other hand, if there is an upstream route, the first cable of all upstream routes is acquired (step S1).
63) All routes whose first cable does not match the cable acquired in step S are extracted as downstream routes (step S164).

Here, the search for the downstream route will be described with reference to FIGS. 10 (a) and 10 (b). For example,
When the search start equipment is other than the loop, as shown in FIG. 10A, if the search start equipment is C1, for example, C
1, R4, C4, R2, C2, R3, C3, R5, C5
Is the downstream route. When the search start facility is R2, R2, C2, R3, C3, R5, and C5 are downstream routes.

Next, when the search start facility is in the branch destination loop and the search start facility is a line facility, all routes that do not pass through the cable connected to the upstream side are regarded as downstream. . As shown in FIG. 10B, if the search start facility is R7, for example, C4, R6, C
5, R7, C6, R8, R9, C8, R10, C7 are the downstream routes. If the search start facility is a point facility, the route branching out of the loop (the first cable does not match any upstream route) is regarded as the downstream. Therefore, if the search start equipment is C5, R
9, C8 is the downstream route.

Next, the search start facility is the main loop (starting point FT
When M is in a loop existing therein, and the search start facility is a line facility, all routes that are graphically connected are regarded as downstream. Therefore, as shown in FIG. 10B, when the search start facility is R3, all the facilities are downstream routes. If the search start facility is a point facility, the route branching out of the loop (the first cable does not match any upstream route) is regarded as the downstream. Therefore, if the search start equipment is C2,
R4 and C3 are the downstream routes.

B-3-7. Search Result Display FIG. 25 is a flow chart for explaining the operation of displaying the search result in the route search (downstream search). First, the equipment (the memory information internal number of the equipment) included in the obtained plurality of routes is acquired (duplication is omitted: step S17).
0). Next, an SIS list is created by extracting only the equipment acquired in step S from the SIS list for all target equipment created in the search target equipment information acquisition processing (step S171). Next, a phase overlay for displaying the search result is created at the top of the drawing, and the display color and the like are set (step S172). Next, the overlay filter is set so that all the figures in the SIS list created in step S171 are displayed (step S).
173). Depending on the overlay settings, equipment on the downstream route will be displayed in blue color.

Is selected and selected (step S180). Next, a menu is displayed by right-clicking and selecting "route search / connection search" (step S181). Next, the equipment ID of the selected equipment is acquired (step S182),
Search for all routes that are graphically connected (step S1
84) and display the search result (step S185). Hereinafter, each process will be described in detail.

B-4-1. Acquisition of Retrieval Target Equipment Information FIG. 27 is a flowchart for explaining the operation of acquiring the retrieval target equipment information in the route search (connection search). If the existing search result is being displayed, it is cleared (the search result display overlay is deleted) (step S19).
0). Next, search for all equipment on the equipment map that is the target of route search from the equipment drawing or equipment registration drawing, and
It is saved in the IS list (step S191). Next, the graphic information of all the equipment in the list is divided into line equipment and point equipment and stored in the memory (step S19).
2). The stored information includes a facility ID, a SIS list number, a feature code, an arrangement point X / Y coordinate (point facility) or a start / end point X / Y coordinate (line facility). And
Proceed to the route search shown in FIG.

B-4-2. Route Search FIG. 28 is a flowchart for explaining the route search operation in the route search (connection search). First,
The type and information of the search start facility is acquired from the data in the memory based on the facility ID of the search start facility (step S20).
0). Next, it is determined whether it is line equipment or point equipment (step S201). Then, in the case of line equipment, a connection search corresponding to the end point direction of the search start equipment is executed to obtain the search result (step S202). Next, the connection start search is performed for the search start facility in the direction of the start point to obtain the search result (step S203), and then the process proceeds to the search result display shown in FIG.

On the other hand, in the case of point equipment, the line equipment whose start point or end point coincides with the arrangement point of the search start equipment is acquired from the data in the memory (step S20).
4). Next, for all the acquired cables, a connection search in the direction opposite to the search start equipment and the opposite end is executed to acquire the search result (step S205), and then the process proceeds to the search result display shown in FIG.

B-4-3. Connection Search FIGS. 29 and 30 are flowcharts for explaining the operation of the connection search in the route search (connection search). First, the cable to be searched and its direction are added to the route information being searched (step S210). next,
From the data in the memory, the point equipment in which the end point in the search direction of the target cable and the arrangement point match is acquired (step S
211). Next, it is determined whether or not the matching point equipment has been earned (step S212).

If the matching point equipment can be acquired, that is, if there is no open end, the point equipment is added to the route information being searched (step S2).
13). Next, it is determined whether or not the point equipment is included in the route that is already being searched, that is, whether or not the point equipment is not searched (step S214). Next, if not searched, the type of point equipment is determined (step S21).
5).

If it is other than FTM, the cable equipment whose start point or end point coincides with the arrangement point of the point equipment and which is not included in the route under search is acquired from the data in the memory (step S216). . Next, it is determined whether or not the corresponding cable equipment has been acquired, that is, whether or not the cable equipment is at the end (step S217). Then, when the corresponding cable equipment can be acquired, a connection search in the direction of the opposite end to the point equipment is executed for all the acquired cables (recursive call: step S218). Then, the route information being searched is returned to the state before the target cable was saved, and the process returns to the calling source (step S220).

On the other hand, in step S212, if there is no matching point equipment, that is, if it is an open end, or if it is searched (loop) in step S214, or in step S215, the point equipment is FMT. If, or in step S217, there is no corresponding cable equipment (end), the end of the route has been reached, so the route information up to this point is stored in memory (step S219), and the route information being searched is then stored. It returns to the state before saving the target cable and returns to the calling source (step S220).

B-4-4. Search Result Display FIG. 31 is a flowchart for explaining the operation of displaying the search result in the route search (connection search). First, the equipment (the memory information internal number of the equipment) included in the obtained plurality of routes is acquired (duplication is omitted: step S23).
0). Next, an SIS list is created by extracting only the equipment acquired in step S from the SIS list for all target equipment created in the search target equipment information acquisition processing (step S231). Next, a phase overlay for displaying the search result is created at the top of the drawing, and the display color and the like are set (step S232). Next, the overlay filter is set so that all the figures in the SIS list created in step S are displayed (step S23).
