工频测量系统,至今仍没脱离模拟方法。因此,测量过程占用设备多、时间长、效率低、实时性差、精度低,远远不能适应现代实时自动测控系统的需要。然而,采用廉价、高性能的单片机却可使这一传统测量方法发生大的变革和突破,下面就常用且急待解决的几种智能工频参数测量方案作一概貌分析。 Frequency measurement system, still not out of the simulation method. Therefore, the measurement process takes more equipment, a long time, low efficiency, poor real-time, low accuracy, far from being able to adapt to the needs of modern real-time automatic measurement and control system. However, the use of low-cost, high-performance single-chip microcomputer can make this traditional measurement methods great changes and breakthroughs, the following commonly used and urgent to address several intelligent frequency parameters measurement program for a profile analysis.
