Toward Wide Area Remote Sensor Calibrations: Applications and Approaches

Remote sensor calibration has emerged as a promising technology in the field of smart grids, enabling reliable calibration of measurement tasks for power sensors. Wide area remote sensor calibration applications require synchronization between the client and server sides for processing dynamic calibration tasks. However, this challenge has not been adequately addressed in prior research. In this article, we first demonstrate a prototype system for remote sensor calibration. Second, based on this system, we address the problem of task synchronization and scheduling in remote sensor calibration systems in an innovative manner. This problem considers both synchronization requirements and the dynamic nature of remote sensor calibration. Subsequently, we propose a novel wide area adaptive synchronous scheduling algorithm called the dynamic synchronous scheduling (DSS) algorithm. This algorithm combines stringent model constraints with dynamic priority adjustments to achieve synchronized collaboration between the calibration clients and servers. Finally, through comprehensive simulation experiments, we validate the effectiveness of the proposed method and its superior performance in terms of overall execution time.
