实用的压力传感信号检测与处理系统设计

介绍一种实用的传感信号检测与处理系统。详细介绍其中的耦合脉冲发生电路模块和信号采集、放大模块。耦合脉冲发生电路用于产生工程用的传感器启动脉冲,其突出的特点是产生的脉冲稳定,且具有良好的逆向阻隔效果。信号采集、放大模块采集传感器信号,用带通滤波器滤除其中的干扰脉冲,并将信号放大。整个系统以单片机为核心,实现对各模块的控制和传感信号采集、处理、存储,用液晶显示器显示结果,并与外界通信。

An Applied Design for Press Sensing Signal Detection and Process System

This text introduced a kind of detection and process system of press sensing signal, practically introduced the module for coupling pulse occurrence circuit and the module for signal collection and amplification.The former module made pulses to start up sensor.Its outstanding characteristic was stability,and good at contrary block.The latter module was used to collect signal,filtrate signal with band-pass filter and amplify it.The whole circuit took single chip microcomputer as a core to control each module of the system.It collected,processed and stored the sensing signal.Then,it displayed the information with liquid crystal display and communicated with environment.
