In this paper we will present the development and implementation of automation, regulation and measurement of heating energy consumption in the University auditorium, which could be used for training and education in different engineering fields (civil engineering, control engineering, process engineering and software engineering). Using a real remotely controlled system, educators are able to demonstrate the real-world principles of thermodynamics, fluid mechanics, and controls as well as to compare data from real systems and from models and software simulations. The presented system is in use at the Faculty of Mechanical Engineering in Kragujevac.

The development of a digital laboratory based on the Internet can be very beneficial, as these systems are inexpensive, easy to install, and allow communication of video and data in real time with a remote computer. We here report the design and construction of experimental equipment which allows remote monitoring of the thermodynamic variables of a cross flow air-water heat exchanger. The experimental equipment and the principal parts are described. Water flow rate is measured with a rotameter; temperatures are measured for both the cold fluid (water) and the hot fluid (air) with thermocuples, and transmitted via internet, in real time to each remote client linked to the digital lab. For this project a commercial graphical programming language, using the USB port for communication between computer and experimental equipment, was used. Programs were implemented to linearize the thermocouple readings, and filters were placed to remove noise from temperature sensors. The front panel of the system, showing important data of the heat exchanger, plots the measured fluids temperature. From these data, the heat transfer coefficient can be calculated. Moreover, the system displays the experiment (video) and the front panel data from a web page to every computer that is linked to the laboratory, so that the remote client can take control, partial or total, of the experiment in real time from any computer. Finally, some conclusions are presented.
Remote Lab Experiments: Measuring and Monitoring of Temperature Changes
International Journal of Online and Biomedical Engineering (iJOE), 2020
The physical training education systems of the faculties of science focus on practical manipulations. Remote Labs are a recent approach used for educating experimental manipulations by using the performance of information and communication technologies. This article presents a real remote laboratory using low-cost embedded systems addressed to engineering and undergraduate students. The manipulation is based on the electronic control system to change the temperature with a plate-form, which is developed to permit students and teacher access to this manipulation. Our purpose of this study is the development of a control system to improve current educational systems in Moroccan universities by managing practical manipulations for a large number of students, based on a web from anywhere and anytime. Measuring and Monitoring of Temperature changes is a new experience of a remote monitoring system that will be allowed the users to access the experiment thought a specific web site.
Computer Aided Laboratory Internal Air, Lighting and Network Control
2016
In this study, Afyon Kocatepe University Dazkırı Vocational School in indoor air of the laboratory is provided lighting and computer-aided control of the outlet. Two temperature sensors to measure the internal and external temperatures of the laboratory to measure the moisture inside and outside the two humidity sensors are used. The data from the sensors are monitored in real time from the computer and can be controlled. Design made with interfaces can be done manually or automatically. Laboratory heating and heating process is also determined as the best temperature for laboratory research in the laboratory with in20OC in automatic mode to maintain a constant. In manual mode set in the heating process is carried out by heating degree. When the media is too hot and the fan stops working and the ambient temperature reaches the desired value. The system is also used in one motion sensor. If breathing is understood that the use of students in 5 minutes when the internal environment re...
Development of a low cost thermal feedback system for basic control education
2011
Temperature is a very important industrial parameter and there is a lot of literature available on temperature control. In this paper, we have presented an experimental setup for temperature control of thermal systems. The electronics includes the firing - angle control circuitry to control the AC power to the filament bulb acting as a heating element. The system is identified as first order using the step response method. Different experiments like on-off control, PID control and digital control have been performed on this setup and the experimental results match with the simulation results. This experimental setup is interfaced with the MATLAB using the DAQ card. A GUI is developed in the MATLAB to make this setup user friendly, providing option like gain setting, anti-windup compensator enable/disable, selection of controller type, selection of sampling time etc. The purpose of this paper is to develop a low cost setup to demonstrate control concepts on a thermal system.

Thermal processes are one of the most common systems in the industry, making its understanding a mandatory skill for control engineers. So, multiple efforts are focused on developing low-cost and portable experimental training rigs recreating the thermal process dynamics and controls, usually limited to SISO or low order 2x2 MIMO systems. This paper presents PHELP, a low-cost, portable, and high order MIMO educational platform for uniformity temperature control training. The platform is composed of an array of 16 Peltier modules as heating elements, with a lower heating and cooling times, resulting in a 16x16 high order MIMO system. A low-cost realtime infrared thermal camera is employed as a temperature feedback sensor instead of a standard thermal sensor, ideal for high order MIMO system sensing and temperature distribution tracking. The control algorithm is developed in Matlab/Simulink and employs an Arduino board in hardware in the loop configuration to apply the control action to each Peltier module in the array. A temperature control experiment is performed, showing that the platform is suitable for teaching and training experiences not only in the classroom but also for engineers in the industry. Furthermore, various abnormal conditions can be introduced so that smart control engineering features can be tested.
