【摘要】：室内通信线缆分布系统是针对室内用户群、用于改善建筑物内移动通信环境的一种成功的方案。在实际工程应用中,室内通信线缆分布图纸一般都基于AutoCAD(Auto Computer Aided Design)系统平台进行绘制,由于AutoCAD只提供了基础的CAD绘图功能,对于室内分布图纸的一些特定需求存在操作繁琐,效率低,准确率低等缺点。为解决这些问题,本文对AutoCAD和ObjectARX的数据结构进行了详细研究,并在此基础上利用ObjectARX对AutoCAD进行二次开发,实现室内通信线缆智能分布系统的设计。实现对室分系统的监控与维护,需在图纸上批量插入RFID(Radio Frequency Identification,无线射频识别)端子,以便监控器件的状态,当监控到故障器件时,可根据连线关系直接在系统图上确定出故障器件,进而通过属性关联在平面图中定位到器件的位置,从而确定实际环境下故障器件的具体位置。主要工作概述如下:(1)设计了针对室内通信线缆分布的图块批量操作模块,同时适用于所有的AutoCAD图块。该模块通过读取图块名称、属性值等属性信息和坐标位置、比例、颜色等几何信息来实现图块的“查”、“增”、“插”、“删”、“改”等功能。所谓“查”是指查询AutoCAD模型空间中所有的图块,并获取这些图块的名称及其属性信息;所谓“增”是指在AutoCAD内存空间上增加一个新的块表记录,并保存新图块的信息;所谓“插”是指在AutoCAD中与世界坐标系相对的一系列位置上,插入图纸自带或用户自定义的图块;所谓“删”是指删除AutoCAD上指定的图块信息;所谓“改”是指更改图块的属性、颜色和几何图形等信息。通过大量的实验,结果证明了该模块的高效性与可行性。(2)设计了针对室内通信线缆分布中器件的连接关系提取模块,该模块可实现系统图上器件与器件之间连接关系的提取。首先需要获得连线的端点位置和实际线缆长度信息,然后通过连线端点与器件的关系确定连线两端的器件,并获取器件的唯一属性标识,然后计算并获取器件的所有端口,并按照一定的规则对端口进行排序,最后将获得的连接关系压入到自定义的容器对象中,也可将容器对象中的数据以Excel表格或其他形式提取出来。通过大量的实验,结果证明了该模块的精确性与可行高效性。(3)设计了针对室内通信线缆分布系统的器件属性关联模块,目的是为了使平面图与系统图之间建立联系。首先,选定系统图上的一个器件,并读取其唯一标识属性值,在AutoCAD中,室内通信线缆分布中的器件都以图块的形式表示,且这些图块中都具有唯一标识该器件的属性。然后在平面图上筛选出与器件属性值相对应的器件,从而实现器件的定位,最后将定位到的器件以两种不同的方式显示:1、在平面图上定位到的器件加上外接矩形,同时将该器件作为视图对象设置为当前视图,使得该器件在当前视图下可以突出显示;2、创建一个新层,将定位到的器件放置到新层上,锁定其他图层,使得其上实体的亮度变暗,从而实现在新层上的器件高亮显示在图纸上。通过大量的实验,结果证明了该模块的高效性与可行性。
[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.
