Abstract

본 발명은 물결의 출렁임 또는 외부잡음의 영향을 받지 않고 수위의 상승 또는 하강을 정확하게 측정할 수 있도록 한 수위변화 측정 방법에 관한 것으로서, 이는 하드웨어적인 로직회로 구성으로서 바람 또는 외부잡음에 의해 물결의 출렁임에 의해 반복되는 신호의 출력으로 실제의 수위레벨변화를 정확하게 측정할 수 없는 종래기술의 문제점을 해소하고자 하는 것이다. 따라서 본 발명은 수위측정 대상의 일정부위마다 복수증으로 고정설치된 수위변화 감지센서로부터 출력되는 두 출력신호의 위상차에 대한 계수값을 증가 또는 감소하는 방법의 프로그램화 수행으로 수위변화를 측정토록 하므로서 외부의 잡음 내지느 물결의 출렁임에도 관계없이 실제 수위변화 측정에 대한 정확성을 꾀할 수가 있다.The present invention relates to a method of measuring a change in water level so that the rising or falling of the water level can be accurately measured without being affected by the wave rumble or external noise, which is a hardware logic circuit configuration and the wave ripple due to wind or external noise. It is to solve the problem of the prior art that can not accurately measure the actual water level change by the output of the signal repeated by. Therefore, the present invention is to measure the change in the water level by programming the method of increasing or decreasing the coefficient value for the phase difference between the two output signals output from the water level change detection sensor fixedly installed in a plurality of increments for each specific portion of the water level measurement target Regardless of the noise or ripple of the wave, the accuracy of the actual level change can be measured.
