In general, deployments of Wireless Sensors Networks in industrial rigs face several constrains, especially those concerning power supply of scattered devices: cabling is expensive and takes a long time, and, on the hand, batteries are sensitive to both current peaks and high temperatures, thus requiring periodic replacement. This work presents a low power router which, by gathering energy from a...
An autonomous, wireless multi-variable smart sensor is presented able to gather, validate, and locally process data on both position alignment and temperature in remotely-operated high-voltage disconnect switches, as part of an instrumentation system which, integrating small, smart, and deeply embedded “field” devices in large numbers, may address the data requirements placed by new sophisticated...
A multi-variable smart sensor is presented able to gather, validate, and locally process data on both temperature and tri-axial vibration, as part of an instrumentation system which, integrating small, smart, and deeply embedded ‘field’ devices in large numbers, may address the data requirements placed by new sophisticated Predictive Maintenance criteria applied to industrial rotating machinery.
This work addresses the integration of wireless nodes organized in meshed Zigbee networks with other nodes linked together over CANbus, which required a special purpose gateway. This solution allowed for transparent flows of information originating in both sensors and actuators in heavy industrial applications, encompassing different requirements regarding data rate and power source, especially in...
In this demo we address an application of a Predictive Maintenance Industrial system, for the monitoring of rotating machinery, which integrates both wired and wireless sensors, which comprise a triaxial acceleration sensor and a temperature sensor, in an Hybrid Network of sensors. The emphasis of the demonstration will be in this dual existence of networks, all integrated in one monitoring system...
