由上图可看出初期交通隧道的设计都偏重于现场总线与以太网混合的复杂通讯结构设计，一方面程序设计人员在现场有较大的软硬件调试工作量，一方面也增加了整个系统数据的采集难度。在中控室中并未设计到其它子系统与实时监控系统之间的整合问题，相互之间都是独立的。将车检器与LED大屏都考虑至现场以PLC的通讯来解决数据采集与控制问题，实际所得到的验证是不可靠、不灵活的，车检数据的采集、转发与存储利用PLC的通讯方式很难取到较为准确的统计数据，以及LED大屏显示常常要以ASCII码的方式写一些天气或致词方面的汉字，由目前的常用的PLC是不能实现的，只能以调用已经建立好的文字列表，以通讯协议方式来切换内容的列表号，而不能灵活的进行汉字的输入。

2）初始硬件通讯结构设计决定了上位软件所发挥的作用较为有限，随着实际工程的验证后，目前的通讯网络结构已经有了较大提升。

由上图可看出硬件通讯结构及系统集成方案都是全以太网的通讯结构，由上位软件通过定制的驱动接口程序直接对车检器及LED进行访问，PLC硬件的逻辑编写与调试也全都在中控室直接下载或上传TV由矩阵的通讯接口与上位软件通讯，紧急电话与消防系统可用API、ODBC等数据访问方式获取数据，这样由客户端操控的就是所有的隧道监控子系统，使得系统的整合较为 。
