본 발명은 교통장해, 교통신호기 및 교통사고 등에 의하여 도로상에서 차량이 정체되어 있는 상태에서, 전방측 차량이 일정거리 이상으로 이동될때 운전자에게 이를 경보케 하므로써 차량을 주행토록 하기 위한 것으로, 더욱 상세하게 설명하면, 사용자 차량내에 초음파 또는 적외선 송신장치 및 초음파 또는 적외선 수신장치를 설치하여 전방측 차량이 일정거리 이내에 정지되어 있을 경우에는 경보음이 발생되지 않도록 하고, 전방측 차량에 일정거리 이상 이동될 때에는 경보음이 발생되도록 하여 운전자가 잠시 피로하여 휴식을 취하는 도중 상기 경보음에 의하여 즉각적으로 운전자세를 취하고 전방차량을 따라 주행할 수 있도록 하거나 또는 전방 차량과의 간격을 좁힐 수 있도록 하므로써 교통이 빈번하 도로에서의 신호대기시 정체현상이 갖은 도로에서 운전자가 잠시잠시 눈을 감고 편안하게 휴식을 취할 수 있도록 하여 운전자의 피로 회복에 도움을 줄 수 있도록 하는 전방차량 이동 경보장치에 관한 것이다.The present invention is to allow the vehicle to run by alerting the driver when the vehicle on the road is congested on the road due to traffic obstacles, traffic signals and traffic accidents, more specifically, In other words, if an ultrasonic or infrared transmitter and an ultrasonic or infrared receiver are installed in the user's vehicle, an alarm sound is not generated when the front vehicle is stopped within a certain distance. The warning sound is generated so that the driver can immediately take the driver's posture and drive along the vehicle ahead, or close the distance with the vehicle ahead while the driver is tired and resting. Congestion in waiting for traffic on the road As related to the forward vehicle movement alarm system that enables by allowing the driver to take a moment, close your eyes while resting comfortably could help the fatigue of the operator.

주지하는 바와 같이 우리나라 뿐 아니라 전세계적으로 기하급수적으로 증가하는 차량에 의하여 대부분의 차량이 좁은 도로상에서 매우 심한 정체현상을 일으켜 교통난이 매우 심각하게 받아들여지고 있다. 특히, 러쉬아워나, 산업도로 또는 명절과 같은 시기에는 도로상에서 적으면 10~20분 심하면 1시간 이상 그대로 차량이 정지된 상태가 지속되거나, 시속 2km~3km 정도로 이동될 수 밖에 없는 사태가 곳곳에서 벌어지고 있다.As it is well known, traffic problems are very seriously received because most vehicles cause very congestion on narrow roads due to the exponential growth of vehicles not only in Korea but also worldwide. In particular, during times of rush hour, industrial roads, or holidays, if the road is small, 10 to 20 minutes or more, the vehicle will remain stationary for more than an hour, or it may be forced to move about 2km to 3km per hour. It's happening.

이와 같은 상태에서는 차량을 운전하는 운전자는 매우 심각한 정서 불안감이 초래되기 마련이어서 피로감이 쉽게 찾아오게 되고, 따라서 대부분의 운전자는 운전대에서 잠시 눈을 감거나, 멍한 상태에서 휴식을 취하게 된다.In such a state, a driver driving a vehicle may cause very serious emotional anxiety, and thus fatigue may be easily found. Therefore, most drivers may close their eyes at the steering wheel or take a rest in a blunt state.

그러나, 차량의 정제시간이 지남에 따라 차량을 조금씩 이동될때, 피로감이 있는 운전자는 순간적으로 전방차량의 이동을 감지할 수 없게 되고, 이에 따라 후방차량의 경적이 아니면 이를 알 수 없어 차량의 정체현상을 더욱 가중시키는 요인이 되고 있을 뿐 아니라, 옆차량의 끼어들기에 의해 더욱 심화되고 있는 실정이다.However, when the vehicle is moved little by little as the refining time of the vehicle passes, the fatigued driver cannot immediately sense the movement of the front vehicle, and thus cannot know this unless the horn of the rear vehicle is congested. Not only has it become a factor to further increase the situation, but the situation is further deepened by the interruption of the next vehicle.

본 발명자는 통상 도시 도로 상에서 신호등에 의해 차량이 정체될 경우에도 쉽게 휴식을 취하게 되고, 이에 따라 후방차량의 경적에 의해 차량을 이동시키는 경우가 매우 빈번한 경험을 하게 되었던바, 전방차량이 임의의 간격이상으로 이동되어 멀어지게 되면 자동적으로 운전자에게 경보음을 고치게 하면 차량의 정체현상을 조금이나마 해소시킬 수 있고, 이에 따라 교통의 원활성을 기할 수 있다는 점에서 본 발명을 창안하게 되었다.The present inventors usually easily rest even when the vehicle is congested by a traffic light on an urban road, and thus, the vehicle is moved very often by the horn of the rear vehicle. The present invention has been conceived in that if a driver moves the alarm sound more than a distance away and automatically corrects an alarm sound, the vehicle can be congested little by little and thus the traffic can be smoothed.

따라서, 본 발명은 초음파 또는 적외선의 송수신기에 의한 전자적 장치에 의해 전방차량의 이동을 감지함과 동시에 경보음을 발하게 하면 본 발명의 목적을 달성할 수 있고, 또 하나는 전방차량과 현차량과의 거리가 일정간격 유지하고 있을 때에는 경보음이 발하지 않도록 하여 차량이 신호등 또는 교통지연에 의해 정체될때 운전자가 잠시 수면하거나 휴식을 취할 수 있도록 하므로써 운전중 피로감을 해소시킬 수 있도록 하는 것이다.Accordingly, the present invention can achieve the object of the present invention by detecting the movement of the front vehicle by the electronic device by the transceiver of the ultrasonic wave or infrared ray and at the same time, the other is the difference between the front vehicle and the current vehicle When the distance is maintained at a certain interval, the alarm sound does not occur so that the driver can sleep or rest for a while when the vehicle is congested by traffic lights or traffic delays, thereby relieving fatigue during driving.

이하, 첨부도면에 의한 실시예를 통해 본 발명을 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제 1 도는 본 발명의 회로블럭도로서, 초음파 송신센서의 공진주파수와 정합되는 주파수 발진회로(1)로부터의 발진주파수는 펄스콘트롤회로(2)에 인가하여 초음파 송신센서를 일정시간 동안 구동시켜 승압회로(3)에 의해 센서의 출력을 증가시킨 다음 센서송신부(4)에서 초음파를 발사케 하는 송신회로부(A)와 전방차량(C)으로부터 반사되어 되돌아오는 초음파를 초음파 수신센서부(5)에서 검출하고, 이 검출된 신호를 증폭회로(6)에서 일정레벨의 신호로 증폭케하며, 이 증폭된 신호중 신호파만 검파회로(7)에서 검출하고, 파형정형회로(8)에서 일정파형으로 정형시킨다음 신호처리회로(9)에서 신호를 하이레벨 또는 저레벨로 출력시켜 지연회로(10)에서 일정시간동안 상기 신호를 출력케 하고, 신호발생회로(11)에서 신호음을 발생케 하는 수신회로부(B)를 갖추어서 되는 것이다.1 is a circuit block diagram of the present invention, in which the oscillation frequency from the frequency oscillation circuit 1 matched with the resonance frequency of the ultrasonic transmission sensor is applied to the pulse control circuit 2 to drive the ultrasonic transmission sensor for a predetermined time. Ultrasonic waves reflected from the front circuit vehicle C and the transmitting circuit unit A for causing the ultrasonic wave to be emitted by the sensor transmitter 4 after increasing the output of the sensor by the circuit 3 are received by the ultrasonic receiving sensor unit 5. The amplified circuit 6 amplifies the detected signal into a signal of a predetermined level, and detects only a signal wave of the amplified signal by the detection circuit 7 and shapes it into a constant waveform by the waveform shaping circuit 8. Then, the signal processing circuit 9 outputs a signal at a high level or a low level so that the delay circuit 10 outputs the signal for a predetermined time and the signal generating circuit 11 generates a signal sound (B). ) It is done by being cold.

제 2 도는 본 발명의 상세회로도로서, 주파수 발진회로(1)는 40KHZ의 신호를 발생시켜 펄스콘트롤회로(2)에서 10HZ의 신호로 콘트롤되게 되고, 트랜지스터(Q1~Q3)로 구성된 승압회로(3)에서 콘트롤된 신호를 승압시켜 센서송신부(4)에서 초음파신호를 방사하도록 한다.2 is a detailed circuit diagram of the present invention, wherein the frequency oscillation circuit 1 generates a signal of 40 KHZ and is controlled by a pulse control circuit 2 with a signal of 10 HZ, and a boost circuit composed of transistors Q 1 to Q 3 . The signal controlled in (3) is boosted to radiate the ultrasonic signal from the sensor transmitter (4).

그리고 수신회로부(B)의 증폭회로(6)는 OP앰프(OP1)(OP2)로 구성하여 수신된 신호를 증폭케 하고, 콘덴서(C1)(C2), 다이오드(D1)(D2)로 구성된 검파 및 파형정형회로(7)(8)에 의해 증폭시킨 신호를 파형정형시키고, 인버터(I)로 구성된 신호처리회로(9)에 입력되게 구성한다.The amplifying circuit 6 of the receiving circuit unit B is composed of an OP amplifier OP 1 (OP 2 ) to amplify the received signal, and a capacitor C 1 (C 2 ), a diode D 1 ( The signal amplified by the detection and waveform shaping circuits 7 and 8 composed of D 2 ) is waveform shaped and configured to be input to the signal processing circuit 9 composed of the inverter I.

만일, 상기 파형정형된 신호가 인버터(I)에 레벨의 신호가 출력되도록 하여 부저(Buzzer)에 경고등이 발생치 않도록 하고, 인버터(I) 입력단에 저레벨의 신호가 입력되면 지연회로(10)가 가지는 시간동안 인버터(I) 출력단에 높은 레벨의 신호가 출력되도록 하여 상기 지연회로(10)가 가지는 시간동안 경보음이 발하도록 구성한다.If the waveform-formed signal outputs a level signal to the inverter I so that a warning lamp does not occur in the buzzer, and a low level signal is input to the input terminal of the inverter I, the delay circuit 10 It is configured to output a high level signal to the output terminal of the inverter (I) for a period of time so that the alarm sounds during the time that the delay circuit 10 has.

즉, 현차량과 전방차량이 정지된 상태에서는 초음파신호가 수신회로(B)에 수신되더라도 부저에서 경보음이 발생하지 않도록 하고, 전방차량이 현차량으로부터 일정간격 이상 멀어지면 일정시간동안 경보음이 발생하도록 하는 신호처리를 인버터(I)로 구성된 신호처리회로(9)에서 실행하도록 한다.That is, in the state where the current vehicle and the front vehicle are stopped, the buzzer does not generate the buzzer even when the ultrasonic signal is received by the receiving circuit B. When the front vehicle moves away from the current vehicle by a predetermined distance or more, the alarm sounds for a predetermined time. The signal processing to be generated is executed in the signal processing circuit 9 composed of the inverter I.

상기에 있어서 초음파 송신 대신에 적외선을 이용할 수도 있다.In the above, infrared rays may be used instead of ultrasonic transmission.

이와 같은 본 발명은 일정 주파수를 발진시켜 펄스콘트롤회로(2)에서 일정시간 동안 센서송신부(4)내의 초음파 송신센서를 구동케 하여 수신센서에 수신케 하므로써 전방차량과 현차량과의 간격이 일정한 간격을 유지할 경우에만 센서송신부(4)에서 초음파가 송신되도록 할 수 있고, 이에 따라 현차량이 일정간격 이상으로 주행중에 있거나, 전방차량측으로 근접하고 있는 도중에는 경보음이 발생되지 않도록 하는 것이다.The present invention as described above oscillates a predetermined frequency to drive the ultrasonic transmitting sensor in the sensor transmitter 4 for a predetermined time in the pulse control circuit (2) to receive the receiving sensor by the interval between the front vehicle and the current vehicle constant interval Ultrasonic waves can be transmitted from the sensor transmitter 4 only when the vehicle is maintained, so that an alarm sound is not generated while the current vehicle is running over a predetermined interval or close to the front vehicle side.

즉, 발사된 초음파가 정지된 전방차량에 의해 반사되어 수신회로부(B)내의 수광센서부(5)에 수신된다 하더라도 신호처리회로(9) 출력단에서 저레벨의 신호를 발생하게 되므로 전방차량과 현차량과의 간격이 일정간격 유지될 경우에는 경보음이 발생되지 않도록 되며, 전방차량이 현차량으로부터 일정간격이상 벌어져 이동될 경우에는 신호처리회로(9)에서 신호음을 발하기 위한 하이레벨의 신호를 출력케 하므로써 현차량의 운전자에게 경보음을 일정시간동안 고지케 할 수 있는 것이다. 따라서, 현차량의 운전자는 현차량이 전방차량과 일정간격 유지된 상태로 정지한 경우에는 잠시 수면 및 휴식을 취할 수 있게 되어 교통난이 심각한 도시에 있어서의 정체시간 또는 장거리 운행중 정체된 지점에서 운전에 도움을 줄 수 있는 피로를 풀수 있는 것이다. 이와 같은 본 발명은 잠시 동안의 휴식에 의해 차량의 안전사고를 미연에 방지할 수 있게 됨은 물론 전방차량과 현차량과의 간격을 필요이상 벌어지지 않게 할 수 있으므로 정체가 심한 경우 교통체중을 원활하게 소통될 수 있는 특징이 있다.That is, even if the emitted ultrasonic wave is reflected by the stationary front vehicle and received by the light receiving sensor unit 5 in the receiving circuit unit B, a low level signal is generated at the output terminal of the signal processing circuit 9, so that the front vehicle and the current vehicle The alarm sound is not generated when the interval between the vehicle and the vehicle is maintained at a constant interval. When the front vehicle is moved away from the current vehicle by a predetermined interval, the signal processing circuit 9 outputs a high level signal to emit a beep. In this way, the driver of the current vehicle can be notified for a certain time. Therefore, the driver of the current vehicle can sleep and rest for a while when the current vehicle stops at a constant interval from the vehicle ahead of time and stop driving in a traffic jam in a serious traffic city or at a point of congestion during long distance operation. It will help you to release your fatigue. The present invention can prevent the safety accident of the vehicle by a short break in advance, and also can prevent the gap between the front vehicle and the current vehicle more than necessary, so that the traffic weight smoothly in case of heavy traffic. There are features that can be communicated.
