이하, 본 발명의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 블록도로, 일정시간 주기로 입력되는 주파수의 변화 및 레벨을 카운트하는 메인 타이머(10)와, 상기 메인 타이머(10)를 통한 주파수의 레벨을 감시하며 입력 캡츄어 및 인터럽트 기능이 없는 마이컴(11)과, 상기 마이컴(11)의 출력레벨에서 과전류를 제한하는 저항(R1)과, 상기 저항(R1)을 통하여 입력되는 신호레벨에 따라 스위칭 온/오프되는 트랜지스터(Q1)와, 상기 트랜지스터(Q1)의 콜렉터에 접속되어 일정전압 이상일 때 턴온되어 정전압을 유지시켜 주는 제너 다이오드(ZD1)와, 상기 제너 다이오드(ZD1)의 캐소우드에 접속되는 정전류의 다이오드(D1)와, 상기 다이오드(D1)와 전원단(VCC)사이에 접속되어 과속시 경고음을 발생시키는 부저(12)로 구성된 것이다.Figure 2 is a block diagram of the present invention, the main timer 10 for counting the change and the level of the frequency input at a predetermined time period, and monitors the level of the frequency through the main timer 10 and the input capture and interrupt function A microcomputer 11 without a resistor, a resistor R1 for limiting overcurrent at an output level of the microcomputer 11, a transistor Q1 switched on / off according to a signal level input through the resistor R1, A zener diode (ZD1) connected to the collector of the transistor (Q1) and turned on to maintain a constant voltage when the voltage is above a predetermined voltage, a diode (D1) of a constant current connected to the cathode of the zener diode (ZD1), and the diode A buzzer 12 is connected between the power supply terminal D1 and the power supply terminal VCC to generate a warning sound when overspeed.
이와같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
본 발명은 메인 타이머(10)에서 주파수의 변화 및 레벨을 카운트하여 일정시간동안 주파수의 레벨 변화가 없으면 마이컴(11)에서 저항(R1)을 통하여 트랜지스터(Q1)의 베이스단을 디세이블(Disable)시키므로 부저(12)가 동작하지 않아 경보음을 발생시키지 않게 된다.In the present invention, when the frequency change and the level are counted by the main timer 10 and there is no change in the level of the frequency for a predetermined time, the microcomputer 11 disables the base terminal of the transistor Q1 through the resistor R1. Therefore, the buzzer 12 does not operate and does not generate an alarm sound.
그러나 만일 주파수 변화가 있으면 마이컴(11)에서 입력 주파수를 소프트웨어적으로 필터링하고 속도가 과속이라고 설정된 속도에 이르면 트랜지스터(Q1)의 베이스단을 액티브시켜 트랜지스터(Q1)를 스위칭 온시키게 되고, 이에따라 부저(12)가 동작하여 경보음을 발생시키게 되는 것이다.However, if there is a frequency change, the microcomputer 11 filters the input frequency by software, and when the speed reaches a speed set to overspeed, the base terminal of the transistor Q1 is activated to switch on the transistor Q1. 12) is activated to generate an alarm sound.
즉, 본 발명은 자동차 계기판에 내장할 수 있는 형태의 속도계 PCB 또는 독자적인 PCB로 구성될 수 있으며, 입력 캡츄어와 입터럽트가 내장되지 않은 저가 및 저용량의 마이컴(11)을 이용하여 속도에 따라 발생되는 속도센서 등의 출력주파수의 레벨변화 및 변화량을 카운트하여 과속이라고 판단되는 지정된 임의의 지점에 도달하면 마이컴(11)의 출력단에 접속된 트랜지스터(Q1)의 베이스단을 도 3의 (B)와 같이 일정시간(500msec) 온시키는 한편 일정시간(688msec) 오프시켜 부저(12) 등의 경보장치를 통하여 경고음을 발생시키게 되는 것이다.That is, the present invention may be composed of a speedometer PCB or an independent PCB in a form that can be embedded in an automobile instrument panel, and is generated according to the speed by using a low-cost and low-capacity microcomputer 11 having no input capturing and interrupt interrupting. When the level change and the amount of change of the output frequency of the speed sensor or the like is reached and the specified random point determined to be overspeed is reached, the base end of the transistor Q1 connected to the output end of the microcomputer 11 is connected to (B) of FIG. As described above, a predetermined time (500 msec) is turned on and a predetermined time (688 msec) is turned off to generate a warning sound through an alarm device such as a buzzer 12.
또한, 본 발명은 일정시간동안 주파수 레벨 변화가 없으면 자동차가 정지하고 있음을 판단하도록 소프트웨어 알고리즘을 구성하여 레벨 카운트 방식에서 나타날 수 있는 경보음 오동작을 막을 수 있으며, 운전자가 경고음을 잘 인지할 수 있도록 경고음 온/오프 시간을 조정할 수 있다.In addition, the present invention can configure the software algorithm to determine that the vehicle is stopped if there is no change in the frequency level for a certain time to prevent the alarm sound malfunction that can appear in the level count method, so that the driver can recognize the warning sound well You can adjust the beep on / off time.
한편, 본 발명은 과속이라고 판단되는 지점에 도달하거나 경고음을 울려주는 속도 지점에서 왔다 갔다할 때 경고음 채터링(Chattering)을 방지시켜 도 3의 (A)와 같이 약 2km/h정도의 히스테리시스를 둔다.On the other hand, the present invention prevents the chattering chattering (Cattering) when reaching the point that is determined to be overspeed or at the speed point that sounds the beep, so that the hysteresis of about 2km / h as shown in Figure 3 (A) .
이상에서 설명한 바와같은 본 발명은 인터럽트 및 입력 캡츄어가 없는 저가용 마이컴을 사용하여 자동차의 과속주행시 이를 경고해 줄 수 있는 효과가 있는 것이다.As described above, the present invention has an effect of warning this when the vehicle is speeding by using a low-cost microcomputer without interrupts and input capturing.
