[Abstract]:In coal mine, the current situation of operation is to use operation ticket step by step, waste time, low efficiency, and also pose a threat to the safety of production and personnel. Based on the practical problems of coal mine, this paper studies a kind of intelligent switching operating system, which is intelligent and fast. This paper discusses the detection methods of coal mine power network parameters, frequency measurement, discrete Fourier frequency measurement and FFT algorithm, phase time detection method, first and second order interpolation measurement, correlation analysis, etc. The detection method based on the fast Fu Li transform and so on. The process of solving these methods is given in detail, and their advantages and disadvantages are compared. Embedded system has been widely used in various fields in recent years, and has great potential for development. He was found in mobile devices, medical devices, and industrial and mining controls. Embedded systems are also widely used in power system devices. Inverter, active filter, etc. It is also applied in data acquisition control, automation device and microcomputer protection. In this paper, the solution of using Samsung S3C2440 as the core processor is proposed, and the hardware circuit is built, including the core circuit, data acquisition circuit, storage circuit, communication circuit and so on. The embedded Linux environment is built, and the cross compiling environment is built. On the basis of hardware, the embedded Linux system is transplanted to realize the analysis and processing of the data. At the same time, the system control interface is developed with Qt/e. The control display interface is intuitive and simple, and the function is powerful. Finally, a prototype is built in the laboratory to simulate. The stability of the test and control system is tested. The interface of the control system and the data of the test bus are given to verify the feasibility of the switching operation control system. Basic completion of the design needs, can complete the switch task.
