Reference numeral 21 is a utility pole subject to automatic equipment placement, and 22 is the utility pole number (210). ), (220), and (230). In addition, 51 to 54 indicate placement position candidates 1 to 4 of the device automatic placement area centered on the target telephone pole, and 23 indicates a device symbol created by automatic placement.

Next, the operation will be described. First, an equipment drawing in which equipment information is written is input by the drawing reading device 11 and stored in the drawing input data storage magnetic disk 14 through the control unit 18. Further, the equipment data held by the host computer 17 is taken into the control unit 18 by the transmission device 16 as needed. Next, after determining all the positions of the electric poles based on the drawing information data stored in the drawing input data storage magnetic disk 14, the equipment of the host computer 17 previously loaded into the control unit 18 via the transmission device 16 Referring to the data, draw an electric wire between the utility pole symbols, and then perform the following procedure to automatically arrange facility equipment symbols such as transformers and switches mounted on the utility pole around the utility pole.

The arranging method will be described with reference to FIG. First,
Inspect the blank area around the target utility pole 21 in the control unit 18,
The placement candidate order is determined in descending order of the central angle of the fan-shaped area of the placement area. In addition, from a plurality of device symbols obtained from the host computer 17, layout candidates are determined in descending order of area of the circumscribing rectangle defined by each symbol. The device symbols are automatically arranged one after another around the target telephone pole in the order determined by the above procedure. These series of processes are executed for all the target utility pole facilities by the software process preset in the control unit 18. The execution result is displayed on the graphic display unit 12, and the operator can proceed with the work only by confirming the displayed result.

The drawing data thus confirmed and corrected is stored in the completed data storage disk 15 as completed data. If necessary, this data can be output as a drawing by the plotter device 19 and can be confirmed. In the present embodiment, the host data held by the host computer 17 has been described as being loaded into the control unit 18 by the transmission device 16, but the loading of host data is not dependent on the transmission device, but may be based on a data medium such as a magnetic tape.

As a result of automatically arranging equipment equipment symbols, the relative positions of the symbols and the symbols and the symbol and the character information. There is a possibility that the intervals may approach or overlap. In such a case, the rearrangement may be automatically performed while finely adjusting the arrangement position in the radial direction around the symbol of the target telephone pole ([Claim 2]).

Further, when the situation described in the above-mentioned other embodiment 1 occurs, it is not rational to perform fine adjustment within an infinite range in the drawing space. Therefore, the radius of the fine adjustment in the radial direction can be changed. A maximum value is set in advance, and if the fine adjustment does not converge even if the maximum value is exceeded, a warning message can be output on the screen to inform the screen operator of the situation. In this case, the image can be drawn at an appropriate position according to the judgment of the screen operator ([Claim 3]).

Further, in general, a distribution equipment drawing has equipment symbols and character information written in high density, and when the equipment symbols are automatically arranged by the above-mentioned method, even if the drawing space is small, the electricity pole equipment can be installed on the electricity pole equipment. It is necessary to write necessary information as close to the telephone pole symbol as possible on the drawing. Therefore, as the method of determining the size of the device symbol to be drawn as described in the embodiment, the contour shape of the device symbol can be used as another means of using the circumscribed rectangle of the symbol. This method does not provide the merit of shortening the processing time of the method that uses the circumscribed rectangle, but it expands the range to automate the drawing of device symbols even in a limited drawing space, and makes the work as manual as possible. A reduction effect can be obtained ([Claim 4]).
