DIGITAL DIAGNOSTI VIDEO SYSTEM FOR MANUFACTURING AND INDUSTRIAL PROCESS

摘要

A diagnostic system for assisting in the diagnosis of a malfunction and other errors in manufacturing machinery is disclosed wherein a plurality of sensors are associated with the machinery at monitoring zones for detecting errors and generating sensor signals representing the errors. The system includes a central control unit having a computer processor in communication with a computer readable medium with a permanent memory. A temporary computer memory communicates with the processor, and a plurality of video cameras are located at the monitoring zones associated with specific sensors. The processor is in communication with the cameras for receiving video output depicting the operation of the manufacturing process continuously in real time. A set of computer readable instructions are embodied within the computer readable medium executable by the processor including set-up instructions for receiving input selecting a first preset duration for a pre-event video and a second preset duration for a post-event video from said video cameras, receiving input selecting machine sensors and cameras triggering and producing the pre-event and post-event videos for the trigger signals, Operating instructions executable by the processor are embodied in computer readable code in the computer medium for continuously storing video output in the temporary memory, continuously receiving available sensor signals, processing the sensor signals to determine if a trigger signal is required, and continuing the preceding operating instructions if a trigger signal is not required. Upon occurrence of a trigger signal the processor executes instructions copying video from the temporary memory into the permanent memory to provide the pre-event video, and begin the recording of the post-event video and storing the post-event video in the permanent memory after completion.
