Comparison of Workbenchs for Telecontrol Systems over the Internet Using Embedded Systems Such as Data Acquisition Cards

Abstract

The objective of this paper is to compare the performance of the workbenches developed in the client-server architecture for internet telecontrol systems using embedded systems as a data acquisition card, with the purpose of determining which of the embedded systems used ( Myrio, CompactRio, Arduino Nano Board) has a better performance considering the transmission, reception and execution times involved in the communication between the controlled system and the controller system. To achieve this objective, a telecontrol client-server communication system was implemented to apply a proportional control action to an unstable system of first order emulated with operational amplifiers and the times involved were measured using an embedded computing system (Raspberry PI) . This in order to characterize the times involved in the telecontrol process using descriptive measures like the ordinary first-order moment (arithmetic average) and the central second-order moment (variance or dispersion) and to determine from the analysis of processing times which had the best result.
