Abstract

본 발명의 귀영자석이 구비된 교차 코일형 계기의 지시값 보상회로는 귀영자석을 구비하고 있는 코일 교차형 계기에서 귀영자석에 의해 지시값이 비선형적으로 변화되는 것을 보상하여 선형적으로 변화되게 하는 것이다.The indication value compensating circuit of the cross coil type gauge provided with the tattoo magnet of the present invention compensates the non-linear change of the indication value by the tattoo magnet in the coil cross type gauge having the tattoo magnet so that it changes linearly. will be.

본 발명은 입력되는 측정신호를 파형 정형기(21)로 파형 정형하고, 이를 주파수/전압 변환기(22)에서 전압으로 변환하여, 함수발생기(23)에서 sin코일 및 cos코일에 각기 인가할 sin함수신호 및 cos함수신호로 변환하며, 이 sin함수신호 및 cos함수신호에 귀영코일(13)에 의한 지시 변화값을 보상한 후 sin코일(11) 및 cos코일(12)에 인가함으로써 지시침의 지시값이 선형적으로 변화되어 표시판의 눈금을 균등하게 분할 및 표시할 수 있다.According to the present invention, the waveform signal is input to the waveform shaper 21, the waveform is converted into a voltage in the frequency / voltage converter 22, and the sin function signal to be applied to the sin coil and the cos coil in the function generator 23, respectively. And the cos function signal, and the sin function signal and the cos function signal are compensated for the change indicated by the tattoo coil 13 and then applied to the sin coil 11 and the cos coil 12 to indicate the indication value of the indicator hand. This linear change can be made to divide and display the scale of the display panel evenly.
