High Flux Isotope Reactor: cooling fans

摘要

Oak Ridge National Laboratory has started monitoring HFIR cooling fans with wireless vibration sensors. The sensors are conventional accelerometers that are connected with a few feet of wire to a wireless hub. At each 6-hour interval, 30 seconds of real-time vibration data is collected from each of the three sensors per motor (there are four motors for the four cooling tower fans). The data is then transmitted wirelessly from the remote data acquisition unit at the cooling towers to the HFIR server, around 250 feet away. Each time that data is collected, vibration statistics are calculated and on-going trends are updated. The server software application provides a "Green - Yellow - Red" visual alert for each motor.
