Vibration monitoring device
First Claim
1. A portable vibration monitoring device for use in connection with a base computer which stores data regarding the nature and parameters of vibration measurements to be made on preselected machines by such device, said device comprising:
- power supply means;
a vibration sensor which produces an analog signal representative of selected vibration of said machine upon mechanically connecting said sensor with said machine at preselected measurement points thereon;
signal conditioning means for conditioning said analog signal generated by said vibration sensor, said signal conditioning means including anti-aliasing means for filtering preselected frequencies from said signal generated by said sensor to enhance the accuracy of the data collected;
means connected with the output of said signal conditioning means including multiple modules which are selectively energized, one of said modules comprising high speed math processor means;
processing means for selectively energizing said modules for purposes of reducing power consumption, for loading and retrieving information and instructions, and for selectively employing said anti-aliasing means for analysing digital information concerning vibration data stored in said device and for selectively interfacing with an operator by causing information to be displayed, and for controlling the various operational modes of said device;
means operably connected to said processing means for entering and loading instructions and information for controlling the operation of said device;
first memory means for storing operating instructions for use by said processing means; and
further memory means for storing data collected by said device from preselected locations upon said machines.

Abstract
A portable vibration monitoring device (10) for use in connection with a base computer (11) which stores data regarding the nature and parameters of vibration measurements to be made on preselected machines for predictive maintenance purposes. The device includes a power module (36) which energizes the various components. A vibration sensor (14) produces an analog signal which is representative of selected vibration parameters. The signal generated by the vibration monitor is conditioned by a signal conditioning module (16) which includes anti-aliasing filters which enhance the accuracy of the data collected. A multiple function module (18) includes various selectively energized modules which enhance the speed and reliability of the data collected. This data is analyzed by a microprocessor and displayed as desired.
