一种新型微机转速测控装置设计

Design of singlechip-based rotate speed measuring and control device

转速测控装置是水电站机组自动控制保护的重要设备。介绍了一种基于单片机和可编程外围芯片(PSD)的双微机、双通道、带有大屏幕液晶显示器的微机转速测控装置的软、硬件设计及应用实效。通过双通道输入信号的采样分析,应用单片机C语言及PSDSoft软件编程。实践表明设计提高了装置运行的可靠性和交互性。

As an important automatic control and protection device in hydraulic power station,the software and hardware design of a rotate speed measuring and control device and its application are introduced. It is based on singlechip and PSD（Programmable System Device）,and equipped with dual- MCU,dual- channel and wide LCD（Liquid Crystal Display） screen. Signals are sampled and analyzed with two redundant channels,and the software is programmed with C and PSDSoft. Practices prove it more reliable and interactional.
