| Abstract: | The paper introduces the basic circuit configuration and working program of the data recorder for low frequency vibration waveform, describes especially the PCMCIA memory card, points out that by using PCMCIA memory card, the transmission time for data transmitted to microcomputer may be saved, and the working efficiency is extremely raised. This provides a route to extend the data memory capacity hereafter. The PCMCIA memory card containing 8 chips of NV SRAM DCM8512B has 4 megabytes. The recorder with working frequency 0～90Hz is available for low frequency vibration measurements, it can record up to 128 times, for each time it records 1 min at least(i.e. one page)with total recording time more than 2 hours. |
