Abstract


The data logger can collect pressure, strain , vibration signal , debugging and fault diagnosis of mechanical , hydraulic system plays an important role . In recent years , micro-electronics technology , computer technology , measurement and control technology and digital communication technologies to flourish , asked the high requirements of the existing data collection : portable , low-power , easy to use , with a variety of optional sampling rate and accuracy, a large storage capacity , and a wealth of possible arithmetic processing function . Microcontroller - based data acquisition is limited by core chip processing speed and computing power , can not meet the performance needs. Therefore , the paper focuses on the problem to conduct research and development of a Portable Data Acquisition Based on DSP and SD card . The paper gives a the collector specific hardware and software design . First, establish the overall function of the collector module design : DSP as the core processor , high - speed data processing and control functions ; using a large -capacity memory card (SD card ) temporarily store collected data ; portable lithium battery power supply ; collector communication with the host computer using the serial communication bus (USB) . Secondly, the hardware circuit design of the collector . The completion of the work , including : chip selection of functional modules , specific circuit design , acquisition the overall PCB board map production , chip installation and commissioning . Then logger software design . The CCS2000 development environment to write a DSP device initialization , AD sampling control , SD card data storage , and the establishment of the FAT16 file system module program . Finally, experimental data acquisition collector to complete 16-channel 50 K / S sampling rate of data acquisition , processing and storage , and use of Matlab tools complete waveform playback . The experiments show that the good performance of the data acquisition processor to achieve the design requirements .
