[Abstract]:The goal of this paper is to design a multi-function continuous casting machine roll gap measuring instrument with independent intellectual property. In the design, DSP chip TMS320F28335 is used as the processor of the roll gap measuring system, and the peripheral hardware circuit is designed with DSP as the core unit. The software design of the multifunction roll gap measuring instrument is completed on the uC/OS-II embedded real-time operating system platform. The data of display and display are analyzed by the software of upper computer, and the data transmission is realized by wireless way. The whole system is designed to measure the physical parameters of continuous casting machine. The data of roll gap value, angle value, guide roll rotation, nozzle spray and so on are collected by sensor, and these data are stored after preliminary processing. Then it is sent to the host computer by wireless transmission, and then analyzed and processed again in the software of the host computer, and then displayed in the form of chart. The maintainers of the caster judge the current condition of the CCM according to the final result. This paper introduces the measuring principle of each physical parameter of the continuous casting machine and the whole software and hardware design scheme of the system. The hardware design is based on DSP processor and internal and external ADC as A / D conversion unit. The hardware platform is composed of signal conditioning, level conversion, display, communication, power supply and other modules. The function of each hardware module circuit is analyzed, and the feasibility of the hardware circuit is verified. The software design is based on hardware and is implemented by embedded system. The transplant of uC/OS-II operating system is accomplished in CCS development environment. After the software design of the system is completed, it is necessary to test the whole system function with the software and hardware. The completion of the whole design has to go through many tests, mainly laboratory tests in the early stage. Some specific test methods are also given, which can only be tested in the field after the laboratory test. The host computer software is mainly used to display the measurement results, and some display methods of the measurement results are given in this paper. And briefly explain how to analyze these displayed data. Finally, the paper summarizes the main work and its existing problems, and puts forward some suggestions and improvement directions for future work, and also makes some discussions on the development of the roll gap meter. It is proved that the multifunctional roll gap meter designed in this paper is reasonable in design, accurate in detection, stable in work, simple in operation, and of high application value.
