闭路电视监控系统 CCTV 在建筑工程中的应用越来越多， 南昌监控. 闭路电视监控系统中传输信号的类型主要有两类 一类是模拟视频信号，传输路径由摄像机到矩阵，从矩阵再到显示器或录像机 一类是数字 信号包括矩阵与摄像机之间的控制信息传输，矩阵中计算机部分的数字信号。 在弱电系统工程中数字信号的传输通常指长线传输，常见的方式有 通过调制、解调方法在电力线或视频线上传输数字信号 通过工业标准的通信网络进行传输，比如 RS422、RS845、RS485 自行开发的自动式传输。 问题往往出现在以下几个方面 第一网络拓扑不合理，未按照总线型网络拓扑布线，成为事宜上的星型拓扑 传输线与接收和发送端设备连接不正确，削弱了平衡线的抗干扰能力 第三公用双绞线，未进一步采取抗干扰措施，比如采用屏蔽双绞线。 根据电磁理论，减少长线上信号反射的唯一途径是阻抗匹配，若通信风格拓扑为总线型，阻抗匹配比较容易实现，但若是星型网 络拓扑，根据工程经验则可按图 1方式进行匹配，在发送端串上与传输线特征阻抗相同的电阻RO，在接收端按图所示进行连接，其中R1 R2，R R1 R２ Ｒ１ Ｒ２ Ｒ０。

3 考虑电缆寿命 软性电缆优于普通电缆，细缆优于粗缆 还有一个最易被忽视的问题 电缆各层间的粘合力，即当电缆各层之间纵向相反方向受力时，是否会发生相对滑动，高层电梯缆长可达100米垂直布线，电缆外护套固定在随行电缆上，这是一种软固定，固定时不允许电缆变形 破坏同轴性 ，这样一来，在电梯反复运动中电缆内部层，在重力作用下，会逐渐下滑，慢慢拉断编织网或芯线，表现为信号逐步减弱，干扰越来越大 目前还没有这项电缆技术标准，简单检查方法是取一米电缆，在一头剥开各层，一人用手握住电缆两端，另一人用钳子拉电缆的内层 依次拉芯线，绝缘层，编织网，体验粘合力的大小，做出合理估计，粘合力差、易滑动的尽量不选用。 与天线接收原理相同，同轴电缆也会接收这些干扰，即干扰电磁场在电缆上产生干扰感应电流，这个干扰感应电流也就会在电缆外导体 编织网 纵向电阻上产生干扰感应电压 电动势 ，这个干扰感应电压刚好串联在视频信号传输回路长长的地线中，形成干扰. 1 常用铜轴电缆 不管是多层高编铜编网电缆、铝箔-编网的双屏蔽电缆、还是铝箔-编网- 铝箔-编网的四屏蔽电缆，电气上都属于一个屏蔽层。
