본 고안은 회전기기의 속도 그라픽 표시장치에 관한 것으로 특히 자동차의 속도표시장치를 발광다이오드로 표시하도록 하는 것이다.The present invention relates to a speed graphic display device of a rotating device, in particular to display the speed display device of the vehicle with a light emitting diode.
모든 회전기기는 최대 허용 회전수가 있으며 이와같은 허용 최대 회전수가 계속되거나 또는 회전수가 초과되는 경우 회전 기기가 마모 되어 위험하다.All rotating machines have maximum allowable revolutions and if such allowable maximum revolutions continue or the revolutions are exceeded, it is dangerous to wear the rotating machines.
따라서 자동차 엔진의 경우2000r.p.m에서 최고 8,000r.p.m까지 있으며 위험수치에 가까우면 경고하도록 되고, 이와같은 표시는 아나로그방식에 의해 경고하도록 되어 있으나 오차가 많고, 직TL하려면 밤인 경우 램프를 켜야만 볼수가 있는 불편이 있었다.Therefore, in the case of car engine, it is up to 8,000rpm at 2000r.pm and it warns if it is close to the dangerous value, and this indication is warned by analog method, but there is a lot of error. There was a inconvenience.
또한 회전기기의 마모등으로 인한 수명 단축을 사전에 미연 방지하기 위하여 종래의 아나로그 방식보다 정확도가 높고, 기기의 마모되는 일이 없이 반영구적이며 특히 자동차와 같이 연료를 사용하는 회전기기를 경고등에 의하여 가속DMF 미연에 방지할수 있는 장치를 제공코자 하는 것이 본 고안의 목적이다.In addition, it is more accurate than the conventional analog method in order to prevent the shortening of the service life due to the wear of the rotating device in advance, and it is semi-permanent without the wear of the device. It is an object of the present invention to provide a device that can prevent acceleration DMF.
상기와같은 목적을 달성하기 위하여 본 고안에서는 종래와는 달리 바늘침에 의해 표시되는 것을 전자로 콘트롤할수 있는 타코미터 집적회로를 사용하여 그래픽으로 표시하도록 했다.In order to achieve the above object, in the present invention, unlike the conventional method, a tachometer integrated circuit capable of electronically controlling what is displayed by the needle needle is displayed graphically.
즉, 자동차의 구동축의 회전에 따라 얻어지는 속도센서에 의해 발생되는 펄스출력을 타고미터집적회로에 입력시켜 입력되는 펄스신호의 수량에 따라 아나로그 신호로 바꾸고 다시 발광다이오드 드라이브 집적회로에 입력시켜서 출력측에 연결되는 발광다이오드를 순차적으로 점등시키도록 한 것이다.That is, the pulse output generated by the speed sensor obtained according to the rotation of the driving shaft of the vehicle is input to the meter integrated circuit, and then converted into an analog signal according to the number of input pulse signals, and then input to the light emitting diode drive integrated circuit again to the output side. The light emitting diodes to be connected are sequentially turned on.
그러나 제2도에 A로 표시되는 곡선도에서 볼수 있는 바와같이 타코미터집적회로의 출력전압이 곡선으로 나타나기 때문에 발광다이오드에 점등되는 신호는 최고속도에 가까울수록 판독하기 어려울 정도로 조밀한 그라픽이 되므로 한정된 숫자의 발광다이오드가 정확하게 표시될수가 없다.However, since the output voltage of the tachometer integrated circuit is shown as a curve as shown in the curve indicated by A in FIG. 2, the signal lit on the light emitting diode becomes a dense graphic that is difficult to read near the maximum speed. The light emitting diode of cannot be displayed correctly.
따라서 본 고안에서는 터코미터 집적회로에서 나오는 곡선 아나로그 신호를 발광다이오드드라이브 집적회로내의 리피턴스 전압을 교정하여 제2도(C)로 도시한 바와 같이 타코미터 집적회로의 출력곡선(A)과는 반대의 곡선을 만들어줌으로써 발광다이오드드라이브 집적회로의 출력신호는 제2도의(B)로 표시되는 바와같이 직선이 되어 결국은 저속으로부터 최대에 이르기까지 같은 간격으로 표시가 될수 있도록 한 것의 특징이다.Therefore, in the present invention, as shown in FIG. 2 (C), the curve analog signal from the tachometer integrated circuit is corrected for the repeater voltage in the light emitting diode drive integrated circuit, and is opposite to the output curve A of the tachometer integrated circuit. By making the curve of the output signal of the LED drive integrated circuit is a straight line as shown in (B) of Fig. 2 is characterized in that it can be displayed at the same interval from the low speed to the maximum.
이하 본 고안을 첨부된 도면에 따라 상술하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안을 설명키위한 전기적회로도로 공지의 속도센서(NS)는 예를 들어 자동차 엔진의 출력축에 연결되어 출력축이 회전하는데 따라 한정된 수의 펄스가 발생되도록되어 있음은 공지와 같다.1 is an electrical circuit diagram for explaining the present invention, a known speed sensor NS is connected to an output shaft of an automobile engine, for example, and a limited number of pulses are generated as the output shaft rotates.
즉, 센서의 회전축에는 4개의 영구자석이 원형으로 부착되어 센서의 회전축이 회전하는데 따라 영구자석의 자력선에 의해 홀 IC가 스위칭 역활을 하도록 되어 있기 때문에 이와같은 홀 IC의 출력펄스가 카프링용 콘덴서(C1)를 통해 파형보정용 저항(R1,R2)과 콘덴서(C2)거쳐 타코미터집적회로(IC1)에 입력되도록 되어 있다.That is, four permanent magnets are circularly attached to the rotating shaft of the sensor, and as the rotating shaft of the sensor rotates, the Hall IC plays a switching role by the magnetic lines of the permanent magnet. C 1 ) is input to the tachometer integrated circuit (IC 1 ) through the waveform correction resistor (R 1, R 2 ) and the capacitor (C 2 ).
이때 저항(R3)은 타코미터집적회로(IC1)의 출력전압을 조정하는 역활을 하도록 되어 있다.At this time, the resistor R 3 serves to adjust the output voltage of the tachometer integrated circuit IC 1 .
즉, 저항(R3)의 갑시 높으면 출력이 커지고, 저항치가 낮으면 낮은 출력을 얻도록 되어 있다.In other words, if the resistance R 3 is suddenly high, the output is large. If the resistance value is low, the output is low.
또 다이오드(D1)와 저항(R1-R5)은 타코미터집적회로(IC1)내의 정전원으로 연결되고 저항(R6)은 타코미터집적회로에 대한 부하 저항으로 연결되어 있다.In addition, the diode D 1 and the resistors R 1 -R 5 are connected to the electrostatic source in the tachometer integrated circuit IC 1 , and the resistor R 6 is connected to the load resistance to the tachometer integrated circuit.
이와같이 된 타코미터집적회로의 아나로그 출력이 발광다이오드 드라이브 집적회로(IC2 ,IC3)에 연결되어 그와같은 출력신호는 각 출력단자에 연결되는 임의 숫자의 발광다이오드(LED1,LED2....LEDn)에 연결되어 회전속도에 따라 순차적으로 점등되도록 되어 있다.The analog output of the tachometer integrated circuit thus connected is connected to the light emitting diode drive integrated circuits (IC 2, IC 3 ) so that the output signal is connected to each output terminal of any number of light emitting diodes (LED 1 , LED 2 .. ..LED n ) is turned on sequentially according to the rotation speed.
이때는 속도센서(SN)에서 나오는 펄스신호는 타코미터 집적회로(IC1')를 거쳐 아나로그 신호로 바뀌는 과정에서 아나로그 신호가 높은 전압쪽의 부분이 제2도(A)로 도시된 바와같이 약30%정도가 곡선을 이루어지므로 본 고안에서는 반고정저항(R1)과 저항(R7)을 LED 드라이브 집적회로(IC3)의 리퍼런스소스단자에 연결함으로써 제2도(C)와 같은 반대곡선을 만들어 아나로그 신호와의 합으로 보정되어 원하는 제2도(B)와 같은 직선을 구함으로써 LED드라이브 집적회로의 수에 따라 발광다이오드(LED1-LEDn)로 눈금을 표시할수 있게 되어 발광다이오드(LED1-LEDn)간의 속도를 50r.p.m으로 부터 200r.p.m의 간격으로 임의 구성할수가 있게 되는 것이다.At this time, the pulse signal from the speed sensor SN is changed to the analog signal through the tachometer integrated circuit IC 1 ′, and the portion of the voltage higher than the analog signal is shown in FIG. Since about 30% is curved, in the present invention, the semi-fixed resistor (R 1 ) and resistor (R 7 ) are connected to the reference source terminal of the LED drive integrated circuit (IC 3 ) so that the opposite curve as shown in FIG. By correcting with the sum of the analog signal and obtaining a straight line as shown in FIG. 2 (B), the scale can be displayed by the LEDs (LED 1 -LED n ) according to the number of LED drive integrated circuits. The speed between (LED 1 -LED n ) can be arbitrarily configured at intervals of 50r.pm to 200r.pm.
따라서 발광다이오드(LED1-LEDn)1개마다의 평균속도 범위가 저속에서 고속에 이르기까지 균일하게 표시할수가 있어서 자동차등에도 사용할수 있는 실용적인 고안인 것이다.Therefore, since the average speed range of each light emitting diode (LED 1 -LED n ) can be displayed uniformly from low speed to high speed, it is a practical design that can be used in automobiles and the like.
