Claim 0:
1. A system for collecting predictive maintenance (PdM) data to establish a condition of equipment in industrial plants or civil structures and to detect at least one suspect condition therein that obtains at least one measurement of motion of the civil structure, equipment or a portion thereof using at least one video acquisition device with an adjustable frame rate that acquires data of the at least one measurement in a video recording of the equipment or civil structure in motion, the video recording comprising video images of the civil structure, equipment or portion thereof which are divisible into individual video image frames, with each individual video image frame being divisible into a plurality of pixels, the system comprising:
a PdM database communicatively coupled to a mobile data acquisition unit (DAU), the PdM database defining the civil structure or equipment under test and a monitoring protocol identifying the at least one measurement to be obtained and a manner for obtaining the at least one measurement;
a data acquisition unit that collects data including the at least one measurement and is positioned to perform surveys within one or more spatial areas containing distinct equipment with an onboard processor and a memory that stores the individual video image frames; and
a first computer program operating in said processor,
wherein the at least one video acquisition device acquires the video images at a sampling rate that captures a plurality of frequencies present in the motion of the equipment or civil structure, and the first computer program operating in said processor adjusts at least one of focus, aperture, and supplemental lighting; automatically locates one or more spatial areas where the motion of the equipment or civil structure is evaluated for the at least one suspect condition; and
transmits the collected data to a PdM server configured with a second computer program that screens the at least one measurement using methods as defined in the PdM database; automatically determines if the at least one suspect condition is present based on the at least one measurement; and reduces an amount of video data archived in the PdM database.
