可计数

Base on the analysis of the grating linear displacement measurement theory,t he measure errors especially the subdivision error of the grating scale,this paper focuses on the theory of switch and merge of dual grating scales'signals,builds the design criteria of high speed high precision displacement measurement by using dual grating sales,designs the switch picking reference with high precision and fast switch and merge method,analyses the errors brought in by switch and merge of the duals grating scales.

针对光栅尺的电子细分信号具有细分误差的特性，本文提出了对莫尔条纹信号不细分的方法以提高双光栅尺信号切换合成值的精度。经过对双光栅计数切换基准、切换与合成特征和规律的探讨，本文设计了实现双光栅尺双重测量、计数值切换合成法的硬件电路，主要通过可编程芯片FPGA，设计了双光栅尺信号处理的各电路模块，如双光栅尺信号四倍频辨向模块、速度判断模块、切换模块、计数值合成处理模块。

In the design of the system, one method of intelligent control is used which combines the Programmable Logical Controller and the Sensor, uses the shaft-type sensor to gather vehicles pulse and the high speed counter of the PLC to count the number of the pulse, uses certain principles of intelligent control to adjust the length of traffic lights automatically according to the data obtained, reduces the phenomenon of the vehicles stranded in a large scale, solves the problems of not equilibrium and unstable traffic flow magnitude well.

在系统的设计中，主要使用了PLC可编程序控制器和传感器相结合的一种智能控制方法，使用压轴式传感器采集车辆脉冲，用PLC高速计数器时脉冲进行计数，根据取得的数据运用一定的智能控制原则自动调节红绿灯的时间长度，最大限度地减少车辆滞留现象，较好地解决了车流量不均衡、不稳定问题。
