IoT Network for Industrial Machine Energy Monitoring

The need to reduce energy consumption and make industrial machines more efficient and the need to reduce energy cost by the optimization of industrial processes can be satisfied by the use of Internet of Things networks for energy monitoring. Internet of Things nodes are constrained devices with internet connectivity and limited computational resources. This paper presents an IPv6 wireless sensor network used to acquire electrical quantities related to the consumption of industrial machines. To test that system was measured the consumption of a hydraulic pump for the actuation of an MTS machine for tensile tests. The sensor node connected to the pump can be reached via its own IPv6 address, and the measured energy quantities are made available through CoAP server resources on the node itself or by the web application of the edge node. This system represent a first stage of the monitoring and control of energy consumption of Industry 4.0 processes for smart energy solutions.
