一般大型發光二極體(LED)顯示器的安裝建立可分成三大階段，規劃、施工及運行。在規劃階段會需要先產出設計圖面讓設計師可以跟相關技師溝通，讓使用者或是審核單位能了解設計細節。在施工階段需要繪製施工圖讓營建單位照圖施作。運行階段需要製作測試圖檔方便維護人員觀察運作狀況。各階段都需要專業人員使用不同工具以應付使用者需求。
在本研究中針對電力系統部分，將三個階段所需要的圖面整合成一個程式，建立好需要的規格，輸入少量數據就可以獲得規劃階段所需的電力單線圖、施工階段的電力佈線圖及運行階段的位置定位圖。本研究以此為目標，利用Python運算相關參數，進而產生繪圖文檔讓ImageMagick繪製所設計的圖面。輸入介面使用Tkinter設計人機介面，讓使用者輸入相關參數。利用這個程式，可以快速產生相關圖檔，幫助使用者節省運算及繪製圖面的時間，加快工程討論及設計文件產出。
本研究製作規劃階段的電力單線圖時，定義一個迴路使用耐流30 A的5.5 mm²電纜，同時兼顧規格統一及施工難易的平衡。使用者輸入LED箱體的長、寬數量，程式就可進一步計算出總耗電、總開關大小、總電纜耐流及尺寸、接地線尺寸、總迴路數及總顯示器尺寸。使用者可以隨時快速調整箱體的長、寬數量，找出適合的尺寸規格。
以此計算結果為基準，繪製出規劃階段的電力單線圖。因為最大耐流的關係，一個迴路最多並聯6個LED箱體，依使用者輸入的LED箱體數量，分配出最適合的組態，進而規劃出施工階段的電力佈線圖。運行階段的位置定位圖重點在於提高使用者的辨識方便度，設計每5個LED箱體就做一個標示，目的是要讓使用者在大面積的範圍內，快速定位任一處異常的座標位置。

The installation and establishment of general large splicing displays can be divided into three major stages: planning, construction and operation. In the planning stage, it is necessary to produce the design surface first so that designers can communicate with relevant technicians. This process allows users or review units to understand design details. In the construction stage, construction drawings need to be drawn for construction units to implement according to the drawings. During the operation phase, test chart files need to be made to facilitate maintenance personnel to observe the operation status. Each stage requires professionals to use different tools in order to meet user needs.
In this study, for the power system part, the drawings required in the three stages are integrated into a single computer program. By establishing required specifications and inputting a small amount of data, the program can generate the power single-line diagrams required in the planning stage, the power wiring diagrams in the construction stage, and the location positioning diagrams in the operation stage. The goal of this is to develop the program, which can facilitate the power planning automation of large-scale LED displays, where the software Python is used to calculate related parameters in order to generate a drawing document, which is used in the software ImageMagick to draw the designed surfaces. The input interface is obtained by using the software Tkinter to design a human-machine interface, which allows users to enter relevant parameters. By using this program, users can quickly generate related graphics files, and the program helps users to save calculation and drawing time, which can speed up engineering discussions and design document outputs.
When this study produces the power single-line diagram at the planning stage, one defines an electric circuit using 5.5-mm² cable with 30-A current resistance. At the same time, both of the uniform specifications and the balance of difficulty in construction are taken into account. User inputs the lengths and widths of the LED cabinets, and then the program can further calculate the total power consumptions, total switch sizes, total cable current resistances and sizes, ground wire sizes, total circuit numbers, and total display sizes. Users can quickly adjust the lengths and widths of the boxes at any time to find out the suitable sizes and specifications.
Based on this calculation results, the program draws a single-line diagram of electric power in the planning stage. Because of the maximum current resistances, a circuit can connect up to 6 LED cabinets in parallel. According to the numbers of LED cabinets input by users, the most suitable configurations are assigned, and then the power wiring diagrams are planned in the construction stage. The position location maps of the operation stage focus on improving users’ identification conveniences, where the design is made by adding a mark every 5 LED boxes. The purpose is to allow users to quickly locate any abnormal coordinate positions within large areas.
