Abstract
Industry 4.0 is leading the Fourth Industrial Revolution transforming traditional factories into smart factories governed by the Internet of Things (IoT). In order to assist smart factory employees, this paper introduces OperaBLE, a Bluetooth Low Energy (BLE) wearable proposal which is aimed at enhancing working conditions and efficiency in Industry 4.0 scenarios. We have developed two innovative algorithms for OperaBLE focused on power awareness as the key-enabling attribute towards success: Low-Frequency Movement Characterisation Algorithm (LoMoCA) and Adaptive Heart Rate Algorithm (AHRA). Novel experiments have been carried out using OperaBLE to determine its operability, reliability, and lifespan. Results obtained during experimentation demonstrate how OperaBLE empowers human-machine collaboration embedding workers in closed-loop performance and ensuring nonharmful working conditions by means of power-aware algorithms. OperaBLE is due to bring digitalisation into smart factories, playing an essential role in the emerging wearable revolution to arise in the following years towards smart production systems.
Highlights
The Fourth Industrial Revolution has arisen to transform the current industry model and to introduce digitalisation into traditional factories improving production rates and promoting collaboration
By the time OperaBLE identifies the beginning of a new movement, the subroutine acquires data from the accelerometer and gyroscope integrated in the inertial measurement unit (IMU) and stores them in the device until the end of the movement
Since several existing algorithms achieve highprecision measurements at the expense of low energy efficiency, we developed a proprietary algorithm which is able to adapt sampling frequency by performing flexible sleeping periods which does not affect the quality of measurements
Summary
The Fourth Industrial Revolution has arisen to transform the current industry model and to introduce digitalisation into traditional factories improving production rates and promoting collaboration This emerging revolution is the widely known Industry 4.0 [1]. Accelerometers are setting the beginning of a new IoT revolution enabling gesture-based systems to enable a better interaction between humans and machines These devices generate huge amounts of data which are due to be processed and filtered to extract specific information, which is a global challenge widely known as big data. OperaBLE is introduced in this paper in order to face the major challenges of Industry 4.0 This BLE-based prototype of work band is intended to bring digitalisation into smart factories and to enhance working conditions by immersing employees into CPS, taking into account human care services for workers.
