QQQQQQQPLC
- 可编程控制器PLC的应用绝大部分都是通过编写梯形图的方式实现程序控制的，但对于智能低压开关系统来讲，其分、断的控制往往要求由主控操作室远程控制来完成。按传统的方法，主控室要对某一个开关柜进行操作，须先发一个控制命令，PLC接收到该控制命令后，再由PLC程序执行该命令，该段程序必须用梯形图或逻辑指令编程，当开关柜数目巨大或要求多路设备同时控制时，PLC的程序编写就比较复杂，尤其是采用脉冲型输出控制而不是用电平保持型控制时更是如此。因为开关柜的分、合控制须两路继电器输出分别控制“分闸”和“合闸”，而

- 随着改革开放的进一步深入，人们的生活水平不断提高，公路交通工具日益先进，要求公路应该具备高速、舒适、安全、经济等要求，所以高速公路得意迅猛发展。同时随着高等级公路的迅速发展，对于路面平整度要求越来越高，路面平整度的合格率既反映了行车舒适程度，又反映了施工队伍的水平。在公路建设中，很多因素会影响到路面平整度，比如施工人员素质、路基施工质量、桥头涵洞两段及桥梁伸缩缝的处理、路面底基层及基层的施工、路面施工机械的选用及路面材料的质量等。由于在检测公路质量的指标中，一个很重要的指标就是平整度，它反映了道
