【摘要】：室內(nèi)通信線纜分布系統(tǒng)是針對室內(nèi)用戶群、用于改善建筑物內(nèi)移動(dòng)通信環(huán)境的一種成功的方案。在實(shí)際工程應(yīng)用中,室內(nèi)通信線纜分布圖紙一般都基于AutoCAD(Auto Computer Aided Design)系統(tǒng)平臺進(jìn)行繪制,由于AutoCAD只提供了基礎(chǔ)的CAD繪圖功能,對于室內(nèi)分布圖紙的一些特定需求存在操作繁瑣,效率低,準(zhǔn)確率低等缺點(diǎn)。為解決這些問題,本文對AutoCAD和ObjectARX的數(shù)據(jù)結(jié)構(gòu)進(jìn)行了詳細(xì)研究,并在此基礎(chǔ)上利用ObjectARX對AutoCAD進(jìn)行二次開發(fā),實(shí)現(xiàn)室內(nèi)通信線纜智能分布系統(tǒng)的設(shè)計(jì)。實(shí)現(xiàn)對室分系統(tǒng)的監(jiān)控與維護(hù),需在圖紙上批量插入RFID(Radio Frequency Identification,無線射頻識別)端子,以便監(jiān)控器件的狀態(tài),當(dāng)監(jiān)控到故障器件時(shí),可根據(jù)連線關(guān)系直接在系統(tǒng)圖上確定出故障器件,進(jìn)而通過屬性關(guān)聯(lián)在平面圖中定位到器件的位置,從而確定實(shí)際環(huán)境下故障器件的具體位置。主要工作概述如下:(1)設(shè)計(jì)了針對室內(nèi)通信線纜分布的圖塊批量操作模塊,同時(shí)適用于所有的AutoCAD圖塊。該模塊通過讀取圖塊名稱、屬性值等屬性信息和坐標(biāo)位置、比例、顏色等幾何信息來實(shí)現(xiàn)圖塊的“查”、“增”、“插”、“刪”、“改”等功能。所謂“查”是指查詢AutoCAD模型空間中所有的圖塊,并獲取這些圖塊的名稱及其屬性信息;所謂“增”是指在AutoCAD內(nèi)存空間上增加一個(gè)新的塊表記錄,并保存新圖塊的信息;所謂“插”是指在AutoCAD中與世界坐標(biāo)系相對的一系列位置上,插入圖紙自帶或用戶自定義的圖塊;所謂“刪”是指刪除AutoCAD上指定的圖塊信息;所謂“改”是指更改圖塊的屬性、顏色和幾何圖形等信息。通過大量的實(shí)驗(yàn),結(jié)果證明了該模塊的高效性與可行性。(2)設(shè)計(jì)了針對室內(nèi)通信線纜分布中器件的連接關(guān)系提取模塊,該模塊可實(shí)現(xiàn)系統(tǒng)圖上器件與器件之間連接關(guān)系的提取。首先需要獲得連線的端點(diǎn)位置和實(shí)際線纜長度信息,然后通過連線端點(diǎn)與器件的關(guān)系確定連線兩端的器件,并獲取器件的唯一屬性標(biāo)識,然后計(jì)算并獲取器件的所有端口,并按照一定的規(guī)則對端口進(jìn)行排序,最后將獲得的連接關(guān)系壓入到自定義的容器對象中,也可將容器對象中的數(shù)據(jù)以Excel表格或其他形式提取出來。通過大量的實(shí)驗(yàn),結(jié)果證明了該模塊的精確性與可行高效性。(3)設(shè)計(jì)了針對室內(nèi)通信線纜分布系統(tǒng)的器件屬性關(guān)聯(lián)模塊,目的是為了使平面圖與系統(tǒng)圖之間建立聯(lián)系。首先,選定系統(tǒng)圖上的一個(gè)器件,并讀取其唯一標(biāo)識屬性值,在AutoCAD中,室內(nèi)通信線纜分布中的器件都以圖塊的形式表示,且這些圖塊中都具有唯一標(biāo)識該器件的屬性。然后在平面圖上篩選出與器件屬性值相對應(yīng)的器件,從而實(shí)現(xiàn)器件的定位,最后將定位到的器件以兩種不同的方式顯示:1、在平面圖上定位到的器件加上外接矩形,同時(shí)將該器件作為視圖對象設(shè)置為當(dāng)前視圖,使得該器件在當(dāng)前視圖下可以突出顯示;2、創(chuàng)建一個(gè)新層,將定位到的器件放置到新層上,鎖定其他圖層,使得其上實(shí)體的亮度變暗,從而實(shí)現(xiàn)在新層上的器件高亮顯示在圖紙上。通過大量的實(shí)驗(yàn),結(jié)果證明了該模塊的高效性與可行性。
[Abstract]:The indoor communication cable distribution system is a successful scheme to improve the mobile communication environment in the building. In the practical engineering application, the distribution drawings of the indoor communication cable are generally based on the AutoCAD (Auto Computer Aided Design) system platform, because AutoCAD only provides the basis of the CAD drawing work. In order to solve these problems, this paper makes a detailed study of the data structure of AutoCAD and ObjectARX, and on this basis uses ObjectARX to open two times of AutoCAD to realize the design of the intelligent distribution system of the indoor communication cable. To monitor and maintain the chamber system, the RFID (Radio Frequency Identification, radio frequency identification) terminal should be inserted on the drawings to monitor the state of the device. When the fault device is monitored, the fault device can be determined directly on the system diagram according to the connection relationship, and then the attribute association is located in the plane map. To determine the location of the device in the actual environment. The main work is summarized as follows: (1) a block batch operation module for the distribution of the indoor communication cable is designed and applied to all AutoCAD blocks. The module is used to read the block name, attribute value and other attribute information and coordinate position, proportion, color and so on. Geometric information to realize the "check", "add", "insert", "insert", "delete", "change" and other functions. The so-called "check" refers to all the blocks in the AutoCAD model space, and obtain the name and attribute information of these blocks; the so-called "increase" means to add a new block table record on the AutoCAD memory space and save the new block. Information; the so-called "plug" refers to the insertion of a drawing or user defined block in a series of positions relative to the world coordinate system in AutoCAD; the so-called "deleting" refers to the deletion of the specified block information on the AutoCAD; the so-called "modification" refers to the changes of the attributes, colors and geometric figures of the block, through a large number of experiments, and results. The efficiency and feasibility of the module are proved. (2) the connection relation extraction module is designed for the device in the distribution of the indoor communication cable. The module can extract the connection between the devices and the devices on the system diagram. First, the end point position and the actual cable length information need to be obtained, and then the connection end point and the device are used. The relationship determines the devices at both ends and obtains the unique attribute identity of the device, then calculates and gets all the ports of the device, and sorts the ports according to certain rules. Finally, the obtained connection relationship is pressed into the custom container object, and the container can be extracted from the image data in Excel form or other form. Through a large number of experiments, the accuracy and feasibility of the module are proved. (3) a device attribute association module is designed for the indoor communication cable distribution system. The purpose is to establish a connection between the plane diagram and the system diagram. First, a device on the system diagram is selected and its unique identification value is read, at AutoCA In D, all the devices in the distribution of the indoor communication cable are represented in the form of a block, and all of these blocks have the only attributes that identify the device. Then, the device is screened out on the plane map that corresponds to the attribute value of the device, thus the device is located. Finally, the positioning device is displayed in two different ways: 1, on the plane diagram. The localed device is added to the rectangle, and the device is set to the view object as the current view, so that the device can be highlighted in the current view; 2, a new layer is created, the localed device is placed on the new layer, the other layer is locked, the brightness of the entity is darkened, so that the device on the new layer is high. A lot of experiments show that the module is efficient and feasible.
