基于单片机的主机测速系统设计

传统船舶主机测速采用带相敏元件的异步测速发电机测速,坚固耐用,缺点是精度不高,存在一定的误差。文章基于AT89C52单片机平台对主机磁脉冲测速系统的硬件部分和软件部分进行设计。通过PROTEUS仿真软件,检测了系统的可靠性与合理性,使该测速系统能利用高效的方法对船舶主机转速进行测量和显示。

The asynchronous speed measuring generator with phase sensitive elements is used to measure the speed of the traditional ship main engine,which is sturdy and durable,but the disadvantage is that the accuracy is not high and there are some errors. In view of these irrationality,the hardware and software parts of the mainframe magnetic pulse velocipede system are designed based on AT89 S52 single chip microcomputer platform. The reliability and rationality of the system are tested by PROTEUS simulation software,so that the speed measurement system can measure and display the rotating speed of the main engine of the ship by using the efficient method.
