| With the rapid development of computer software and hardware technology, based on thecomputer analysis system of remote, online, real-time measurement is the future measurement(detection, monitoring) development direction. Especially the innovation research ofcomputer test system of optical, electric field based on the physics principle is extremelyimportant and the development of measurement technology to improve.Based on the basic electromagnetic instrument in detail (ballistic galvanometer,oscillograph) measuring principle, design and Research on the basis of such instrumentationsystem creatively, using the technology of embedded system, a CCD imaging system,computer image processing combined, to overcome the traditional impact galvanometeroscillograph, end system observation link great error (by human judgment), theelectromagnetic parameters (voltage, current, capacitance, high resistance) test processing,design out an efficient, fast, dynamic testing system based on the coil of the electromagneticvibration optical amplification.The design of the overall system mainly consists of the following four parts:electromagnetic vibration system, SCM system, optical system, computer program. The mainelectromagnetic vibration system comprises an oscillating coil radial magnet, with mirror;SCM system is the smallest single-chip system, analog to digital to analog converter, liquidcrystal display screen; the light path system consists of semiconductor laser, a parallel lighttube, light, high speed industrial CCD machine; computer program is composed of interfaceprogram of VC6.0development the analysis of motion information, complete the CCDacquisition images focused spot extraction, processing, measurement, electrical relatedquantities.Finally, two kinds of hardware platform is built and tested, the functional operation ofthe system’s normal, achieved the expected design requirements, has a certain practicalapplication value. |
