Design of embedded-based ceramic tile linear thermal expansion testing system

In order to realise the automatic determination of linear thermal expansion of ceramic tiles, this paper designs the overall solution of the ceramic tile linear thermal expansion testing system. The upper computer software was designed using C# language and the STC8H8K64U microcontroller was used to implement the linear temperature rise control of the electric heater using a fuzzy adaptive PID control algorithm. The upper computer software is operated online with the controller to achieve the acquisition, storage, analysis and real-time curve plotting of temperature and displacement data to meet the testing requirements of ceramic tile production for linear thermal expansion index of ceramic tiles.
