基于VME总线的高精度温度测量板卡FPGA设计

Design of High Precision Temperature Measurement Board FPGA Based on VME Bus

在现代大型环境控制系统中,高精度温度测量是实施精确控制的前提。而高精度温度测量单元也对本身的控制提出了较高的要求。本文给出了一种利用FPGA来实现测量板卡整个工作流程和VME总线接口的控制方式,与传统采用微控器相比,此控制方案具有设计性能更优、设计思路更清晰、周期短、成本低等优点。

In modern large- scale environmental control system, high precision temperature measurement is the prerequisite for the implementation of precise control. The high precision temperature measurement unit also puts forward higher requirements for the control of its own. This paper presented a way to control the whole working process of the card and the VME bus interface by using FPGA. Compared with the traditional microcontroller, the control scheme has the advantages of better design performance, clearer design idea,shorter cycle time and lower cost.
