A remote manufacturing monitoring system based on the Internet of Things

A remote manufacturing monitoring system based on sensors, RFID (Radio Frequency Identification) and network is designed for keeping track of information which industrial machines are evaluated with. Different sensors, such as, temperature transducer, pressure transducer, noise transducer, current sensor, revolution speed transducer, vibration frequency transducer and RFID tags, are employed in the system to collect information from the industrial machines. The lower-layer field data collection system is linked with the upper-layer monitoring and diagnosis application system via Zigbee, industry Ethernet and WiFi (Wireless Fidelity). The monitoring system is implemented on machine tools with a user friendly interface. The tests show that the system could check machine tool status efficiently. Both software and hardware implementation are demonstrated in this work.
