Abstract


Centrifuge is a kind of instrument that be widely used in separation of sample analysis. With the economic development rapidly, the market demand for centrifuge more and more, moreover the relevant sectors require the performance higher and higher. The traditional "workshop mode", "bench mode" have the low-level work repeat continually, also extended the development cycle greatly. To this end, building a universal platform to develop centrifuge is necessary, it will simplify the develop process and improve the develop efficiency; also provide the developers with a useful references of selection.Firstly, the paper overall plan the projects about the development platform, and analysis of the issues should be paid attention to and the steps, the principle should be follow in the development process. Followed,aim at the functional structure for the centrifuge, discussing in detail the selection and modular of hardware and software resources, focused on the MCU selectuon, the motors control, the velocity measurement and the digital PID algorithm. Finally, take the medical intelligence centrifuge development as a specific study object to achieve a common development platform. With the wave simulation device debugging, this system completed the TGL series of centrifuge development, production and application.This universal development platform has been used, the trial proof, compared to the traditional "bench" development pattern, it achieve the product development with shorter cycle, lower cost. The modular hardware and software design improve the overall stability of the centrifuges greatly. Digital PWM and PID regulator will make the measurement parameters more accurate and control the process is more reliable; also, automatic identification of rotor system and remote monitoring system enables users to set a higher operational safety.
