摘要
就微机调速器的测频方式、测频的冗余、数字测频硬件选择、测频分辨率与测频采样周期、PLC调速器测频方法、PCC调速器测频、齿盘测速回路等方面展开分析,希望能对微机调速器的研发、设计、验收、标准制定等相关部门提供参考性的意见和建议。
This paper analyzes the frequency measurement modes, frequency measurement redundancy, hardware selection for digital frequency measurement, frequency measurement resolution and sampling cycle of microcomputer speed governor, and PLC speed governor's frequency measurement method, PCC speed governor's frequency measurement, frequency measurement loop by gear and so on. It is hoped that it could provide reference opinions and suggestions for the departments concerned on development, design, acceptance and standard establishment.
