摘要
本文提出了新型录像机伺服/控制/定时功能一体化数字集成控制系统的设计思想,进行了相应软、硬件系统的设计,给出了软件伺服算法,所有设计功能均在单片微处理器μPD—78148上编程实现。经仿真调试,达到了预期的结果。该系统可以替换当前录像机伺服控制系统和定时器系统相分离的双微处理器系统结构,适应录像机高集成度、小型化与多功能的发展趋势。
This paper presents the design idea of digital integrated control system, which realizes servo, control and timing functions with only one MPU, for home VCRs. The related hardware and software system are developed. The software algorithm of servo system is given. All the functions are programmed and realized on signle chip microprocessor μPD78148.This system can replace the separate two MPU system of current VCRs. This technology satisfies the market trend to demand the VCR having a further size and weight reduction, multifunction and higher performance.
