Thermal Energy Harvesting based Novel Wireless Sensor Node with Wired Measurement for Condition Monitoring of Gearbox
الملخص
Abstract: during operation processes, industrial rotating machines revolve at variable speed under different loads. Under such operating conditions a heat would be generated within the internal components. Yet, temperature may increase within the machines when a fault is developing inside them. Therefore, the temperature of machines can be used effectively to monitor the condition of industrial equipment. This comparative study investigates the use of a novel wireless temperature node and compares the results obtained by wired measurement one. Both nodes are used to monitor the condition a gearbox transmission system under different operating circumstances. That is, the wireless temperature node was fabricated with a novel feature in that it is supplied by a thermoelectric generator module. The module is mounted on the gearbox without the need of using a wired power source or the requirement for recharging, or changing, batteries. Data collected by the node is transferred via a Low Energy Bluetooth and received by CC2540. The collected data is then analysed using a portable monitoring device, such as a PC. Results obtained show that the system can provides reliable monitoring information about the temperature of the monitored gearboxes. Experiments performed demonstrate an outstanding performance of the proposed system which make it suitable for wireless and wired condition monitoring purposes.
