便携式信号采集在机器健康诊断系统中有较高的应用价值。机器健康诊断的信号特点是包括低频信号。本文研究是为了实现简易而且低成本的低频便携式信号采集。以MicroChIP公司单片机PIC18F1320为核心设计信号采集电路,实现了信号的采集和保存。系统采用串行电可擦除芯片24LC32A保存数据,经过有线通信,信号数据由串行口通过MAX232芯片输送到微型计算机接收和保存,最后绘制出信号波形。 微型计算机程序采用Visual Basic编程。研究成功采样频率为3 kHz的复杂信号,证明该方案符合设计要求。 Abstract: Portable signal acquisition is useful in machine health monitoring systems. The signal characteristics of machine health monitoring includes low frequency signals. The goal of this study is to realize simple, inexpensive and portable low frequency signal sampling. This paper provides the project of signal acquisition system design based on PIC18F1320 microcontroller manufactured by the MicroChIP Technology Incorporation to achieve signal sampling and storage. The system adopted EEPROM 24LC32A to store the signal data. The microcomputer received data via wired link with the MAX232 IC through the serial port. The microcomputer program, programmed in Visual Basic, received the data, stored it and plotted the signal. The study successfully samples 3kHz complicated signals and thus meets the design requirement.

Digitemp Junior – An RS-232 Port-Powered Digital Thermometer Digitemp Jr. is a device that is designed to measure and report ambient temperature. When connected to an RS-232 port on any PC, it will periodically measure and report in ASCII form the ambient temperature in degrees Celsius. These temperature readings can be monitored with any terminal program. If the terminal program supports capture to disk, the temperature readings can be saved to disk for further analysis with a spreadsheet program or other data analysis tool. The simple ASCII output format of Digitemp Jr. makes it rel- atively easy to write custom software for receiving, recording, and analyzing ambient temperature data. Best of all, Digitemp Jr. requires no external power sup- plies or batteries. It is powered directly by the RS-232 port.
