Design of the device of auto-measuring radon continuously based on FPGA

介绍了基于FPGA的连续自动测氡仪的测量系统的设计。该系统核心是FPGA控制系统的设计,控制部分主要由预置模块、电子万年历模块和驱动模块等构成;实现了对氡浓度和氡析出率的连续自动测量,信息数据采用LCD显示,超高速微型打印机自动打印最后的测量结果。采用FPGA来设计连续自动测氡仪的测量系统,提高了系统的精度和稳定度。

This paper introduces the design of the device of auto-measuring radon continuously. The core of the system is the design of controlling system by FPGA, which consists of preset module, electrical calendar module and driving module. The system can automatically measure the consistence of the radon and the separating out rate of it. The information data is displayed by LCD. The high speed micro printer is used to print the measuring result. It adopts FPGA to design the measuring system of the device, which can improve the precision and stability of the system.
