A Measurement and Analyze System for the KY231 Material Strain Tester Base on STM8S207 and Virtual Instrument

Abstract:

A measurement and analysis system is designed base on the requirement of digital upgrade to the KY231 Material strain tester. This system is made up of two parts :The analyze system based on the LABWINDOWS and the measurement system based on STM8S207. The physical quantities (such as stress, pressure, deformation, etc.) of the metal specimen are acquired, displayed and analyzed digitally in this system, meanwhile the experimental data and curves can be stored in the systerm and compared to the historical data saved in the previous files. Because the USB interface is too complex to the MCU systerm form the aspart of the programming and circuit design, the PL2303 is used to simulate USB interface as virtual RS232 for the communication between the measurement system and the analyze system.
