[Abstract]:Cement is an important building material, its application is very extensive. Cement bending testing machine is an important instrument for bending strength of cement samples. With the development of society, the original cement bending tester has been difficult to meet the needs of users in control, accuracy, data processing and so on. Therefore, a bending tester based on embedded Linux platform is proposed to improve the data processing ability and control accuracy of the system. The purpose of this paper is to design a measurement and control system which can collect signals with high precision and display them in real time. Based on the composition and development of cement bending tester, the advantages, disadvantages and development trend of bending tester are studied in this paper. In the process of system design, it is divided into two parts: hardware design and software design. The hardware design part, including power module, LCD module, USB module and so on, introduces the method of hardware system construction. Through the sensor to achieve the collection of measurement data, so as to analyze, process and display the data. In the process of software design, the installation process of Linux and the design of serial port driver are introduced. The man-machine interface uses Qt, to display the test results. In this paper, the measurement and control system of cement bending tester is designed based on ARM, the hardware selection and measurement and control circuit design are completed, the measurement and control software based on Linux system is compiled, and the whole system is tested. The measurement and control system designed in this paper, through modular design, realizes the purpose of measuring, processing and displaying the bending strength of cement, the accuracy of the measured data meets the requirements, the data processing ability is strong, and the accurate automatic control is realized, which has good real-time performance and achieves the expected effect.
