Abstract: The paper introduced basic principle of capacitive sensing touch technology, proposed a design scheme of control panel of collector based on PSoC chip CY8C24794, and introduced design methods of capacitive touch button and slider, monitoring module and USB communication interface between the control panel and computer module in details. The application in a novel RAID collector showed that measuring error of environmental parameters of the control panel is less than 3%, the measuring error of touching button is less than 2%, and the fault ratio is 0.
