摘要
电阻层析成像技术(Electrical Resistance Tomography,简称ERT)是一种可用于液—固,气—液两相流检测的一种高新测量技术。文中主要介绍ERT系统的概念与应用、ERT系统硬件构成、设计方案、器件选择、A/D转换以及如何利用单片机C8051F040实现对电路各模块的控制,从而实现ERT系统的微弱信号采集。
Electrical Resistance Tomography is a new technology which can be used in liquid/solid and gas/liquid measurement. This article introduces the basic concepts, application, hardware constitution, component choice and A/D conversion of the ERT system as well as how to control the procedure of every module using the single-chip integrated circuit C8051 F040, so that the device can accomplish the weak signal detection of the ERT system.
