Vibration sensing for equipment's health monitoring in power substations using wireless sensors

Optimization of energy consumption of wireless sensor network for information transmission system of computer numerical control machine

“…Data on motor performance is transmitted to a computer and analyzed using the WirelessHART standard to identify early signs of bearing failure [2] ; ②the WiBeaM system, designed by an Indian research institute, is primarily used to detect the status of induction motor bearings and is designed to take into account the general conditions that arise during the operating duty cycle of a motor. The researchers used a monitoring node dormancy strategy to capture monitoring readings at least once a day and greatly reduce energy consumption [3] ; ③ Nasipuri et al used a WSN with 74 MICAz nodes to monitor the health of transformer fans and air compressors in substations based on vibration signals [4] ; ④Researchers at Tongji University in China transplanted the IEEE 802.15.4 protocol ported to GAINZ nodes, which allows the nodes to monitor low-frequency vibration more economically and efficiently [5] ; ⑤ Weiwei Cai et al designed a WSN node that enables mechanical vibration signal acquisition and on-chip processing, using a dual-core architecture consisting of an STM32 microcontroller and a TI2430 chip to pick up vibration signals using acceleration sensors [6] .…”

Online monitoring of power data through wireless sensor network

“…These nodes help to collect the data for various parameters of a system and co-operatively pass the collected data to the control station. These wireless sensor kits consist of small semiconductors, microcontrollers, radio transceivers and other smaller components all integrated on the kit to produce a single node [17]. These sensor nodes act as the tag, routers and gateway.…”
