Design of electronic programmable board with user-friendly touch screen interface for management and control of thermosolar plant parameters

This paper describes a programmable electronic unit for controlling the environmental parameters and managing the electrical functions of a civil/industrial thermo-solar plant. The control unit acquires data from five analog temperature sensors, processes this informations and, on the basis of them, commands a series of external equipments (pumps, electric valves and power supllies) with dedicated relay outputs. In addition to, the designed electronic system has a display for graphical interface with users in order to ensure simple programming and managing and lastly it’s manageable even remotely. The electronic board, integrated with the display embedded system, allows the optimization of plant performances in order to maximize efficiency and energy saving; obviously, the system is designed in general purpose concept and, being widely programmable, its functionalities can be simply and quickly modified by user through the touch screen display.
