Intelligent Switching Operation Control System Based On Embedded System

In the coal mine, switching operation is using the operating status according to the ticketsstep by step, not only waste of time, inefficiency, but also a threat to the safe of personnel andthe produce lines. In this paper, from the practical problems in coal mine, make a study of anintelligent switch operating system, do the operation safely and quickly.This paper discusses ways of detection mine network parameters, the frequency of thecommon cycle frequency measurement, frequency measurement, etc. Discrete Fourier, phasedetection phase-time detection methods, a second-order interpolation measurements, correlationanalysis, based on the Fourier transform detection methods. And make a details of the process ofsolving these methods, comparing their advantages and disadvantages.Embedded technology applications in the power system has a long history, widely used fordata acquisition, automatic devices, instrumentation, distributed control and other fields, which ismore typical of the data collection and monitoring, computer protection, automatic devices, Inthis paper, the actual needs, make use of Samsung S3C2440processor as the core solution, builda hardware circuit, including the core circuit, data acquisition circuit, memory circuit,communication circuit. Do detail explanations of how to build the embedded Linux environment,make the cross-compiler environment to prepare the establishment of such links. And hardwarebased on the transplantation of embedded Linux, data analysis and processing, using Qt/e forthe system control interface development, the interface simple and intuitive, and powerful.Finally, build a simulation prototype in the lab to verify detection and control system’sstability, and gives the control system network interface and test data to verify switch operationto complete the design for basic needs, and can do the switching operation well.
