激光测距系统中高速并行数据接口的研究

Study on High Speed Apposition Data Interface in the Laser Distance Measurement System

本文介绍了基于红外激光定位技术的矿井提升机位置跟踪系统和双口RAM在矿井测距系统中的应用,介绍了高性能双口RAM IDT7132芯片的工作原理;并针对其不同的工作方式,提出了硬件判优和软件判优两种实现方法,给出了利用双口RAM进行数据交换的软件设计流程.该系统具有无传递误差,无需辅助校正开关,能极其准确地显示提升机的实际位置,实现对提升机的数字化速度控制。

This paper introduces the study of mine hoister tracking system based on infra-red laser orientation technique, the application of dual-port RAM in the distance measurement system of mine hoister and gives an operation theory of dual-port RAM IDT7132. According to its different operation modes, the hardware arbitration and software arbitration are presented, and the flow chart of data exchange with IDT7132 is given. This measure has no transmission error and no need of assistant correcting switch. At the same time, it can show the actual location of mine hoister to realize controlling the digitized speed of the hoister.
