Abstract
Description
본 발명은 디프로스터 구동기간 자동설정 시스템에 관한 것으로, 동절기 운전자가 성애제거를 위해 디프로스터를 작동시킬 경우 수온 게이지 센서와 외부 온도 센서에서 감지된 두 센서의 온도차와 성애가 끼는 데이터 설정값을 비교하여 상기 두 센서의 온도차가 상기 데이터 설정값 보다 더 크게 되면 이를 에탁스 내의 마이콤이 감지하고 디프로스터 릴레이를 작동시켜 열선에 전원을 공급하여 성애를 제거하고, 열선 앞단에 미소저항을 설치하여 상기 마이콤에서 미소저항을 지나가는 전류량을 검출하여 이 전류량의 정도를 판단하고, 성애제거 완료시 디프로스터 릴레이를 오프시켜 주게 되어, 성애가 적은 경우에는 빨리 제거되어 나머지 시간동안 동력이 낭비되고, 성애가 많은 경우에는 시간이 모자라서 다시 스위치를 조작해야 하는 불편함을 해소하는데 있다.The present invention relates to a system for automatically setting the defroster driving period. When the winter driver operates the defroster to remove the defroster, the temperature difference between the two sensors detected by the water temperature gauge sensor and the external temperature sensor is compared with the data setting values of the defroster. When the temperature difference between the two sensors is greater than the data set value, the microcomputer in the etax detects this, operates the defroster relay, supplies power to the heating wire, removes frost, and installs a micro resistor in front of the heating wire. Detects the amount of current passing through the micro-resistance at, and determines the degree of this current, and turns off the defroster relay when the defrosting is completed.If the defrost is small, it is quickly removed and the power is wasted for the rest of the time. The inconvenience of having to operate the switch again It is to solve.
일반적으로 종래의 디프로스터 구동 시스템은 에탁스 내에 장착되어 있고, 디프로스터 스위치, 디프로스터 릴레이, 알터네이터 'L'단자 및 디프로스터로 구성되어 있다.In general, a conventional defroster drive system is mounted in an etax and consists of a defroster switch, a defroster relay, an alternator 'L' terminal and a defroster.
그 동작 상태를 보면, 운전자가 이그니션 1단 스위치(70)를 온시켜 차량이 시동되면 알터네이터(40)의 'L'단자는 12V 전압레벨로 상승하게 되고, 에탁스(20)의 'L'단자에 12V가 입력되어 상기 에탁스(20)는 열선(60)를 구동시킬 준비가 된다.In the operation state, when the driver turns on the ignition first switch 70 and the vehicle is started, the 'L' terminal of the alternator 40 rises to a 12V voltage level, and the 'L' terminal of the Etax 20. 12V is input to the ETAX 20 is ready to drive the heating wire (60).
다음에, 운전자가 디프로스터 스위치(10)를 온하면 상기 에탁스(20)는 디프로스터 릴레이(30)를 구동시키어 열선(60)에 전원(Batt+)이 공급되어 글라스의 성애를 제거하게 된다.Next, when the driver turns on the defroster switch 10, the etax 20 drives the defroster relay 30 to supply power Batt + to the heating wire 60 to remove the glass defrost.
이와 같이 작동하는 종래의 디프로스터 시스템은 운전자가 제 때에 스위치를 오프하지 않으면 성애 제거 정도에 관계없이 일정하게 정해진 시간동안(대개 15∼30분)만 동작한다.Conventional defroster systems operating in this way only operate for a fixed amount of time (usually 15-30 minutes), regardless of the degree of defrosting, unless the driver switches off in time.
따라서, 설정된 에탁스(20)의 타이머의 구동시간에 비해 성애가 적은 경우에는 성애가 빠리 제거하게 되므로 나머지 시간동안 동력이 낭비되고, 반대로 설정된 에탁스(20)의 타이머의 구동시간에 비해 성애가 많을 경우에는 타이머의 시간이 부족하게 되어 다시 스위치를 온시켜야 하는 불편함이 있으므로 이에 대한 개선이 필요하게 된다.Therefore, when the sex is less than the set driving time of the timer of the Etax 20, since the sex is removed quickly, power is wasted for the rest of the time, and the sex is compared with the driving time of the timer of the Etax 20 set. In many cases, there is an inconvenience of having to turn the switch on again because the timer runs out of time, and thus an improvement is required.
본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 동절기 운전자가 성애제거를 위해 디프로스터를 동작시킬 경우에 수온 게이지 센서와 외부 온도 센서에서 감지된 두 센서의 온도차와 성애가 끼는 데이터 설정값을 비교하여 상기 두 센서의 온도차가 상기 데이터 설정값 보다 더 크게 되면 이를 에탁스 내의 마이콤이 감지하고 디프로스터 릴레이를 작동시켜 열선에 전원을 공급하여 성애를 제거하고, 열선 앞단에 미소저항을 설치하여 상기 마이콤에서 미소저항을 지나가는 전류량을 검출하여 이 전류량의 정도를 판단하여 성애제거 완료시 디프로스터 릴레이를 오프시키도록 한 디프로스터 구동시간 자동설정 시스템을 제공하는데 그 목적이 있다.The present invention has been made in view of the above, when the winter driver operates the defroster for defrosting the temperature difference between the temperature difference between the two sensors detected by the water temperature gauge sensor and the external temperature sensor and the data set value affects the sex In comparison, if the temperature difference between the two sensors is greater than the data set value, the microcomputer in the etax detects this, operates the defroster relay, supplies power to the heating wire, removes frost, and installs a micro resistor in front of the heating wire. The purpose of the present invention is to provide a system for automatically setting the defroster driving time by detecting the amount of current passing through the micro resistor in the microcomputer and determining the degree of the current amount so that the defroster relay is turned off when the defrosting is completed.

이하, 첨부 도면을 참조하여 본 발명의 구성에 대하여 살펴보면 다음과 같다.Hereinafter, the configuration of the present invention with reference to the accompanying drawings.
차량의 내부와 외부 온도를 감지하는 수온 게이지 센서(140)와 외부 온도 센서(150)가 에탁스(ETACS)(80)의 마이콤(90)의 입력단에 연결된 비교기(180')에 연결되고, 상기 비교기(180')에서 비교된 비교값을 입력신호로 상기 마이콤(90)의 제어를 받아 릴레이 작동으로 밧데리 전원이 열선으로 공급되어 성애 제거가 이루어지도록 구성되어 있되, 상기 밧데리(Batt+)와 열선(130) 사이에 미소저항이 연결되어 그 양단의 전압차를 감지하여 이를 전류량으로 환산하여(미도시) 계속 전류량을 비교하여 마이콤(90)의 제어로 밧데리(Batt+) 전원의 공급/차단 시기를 결정하고, 이 열선(130)에는 상기 미소저항(110)의 온도를 일정하게 유지시켜 주는 히터(120)가 구비되어 있는 것을 특징으로 한다.The water temperature gauge sensor 140 and the external temperature sensor 150 for detecting the inside and outside temperature of the vehicle are connected to a comparator 180 'connected to the input terminal of the microcomputer 90 of the Etax 80. Under the control of the microcomputer 90 using the comparison value compared in the comparator 180 ′, the battery power is supplied to the heating wire by the relay operation, and the defrosting is performed, but the battery (Batt +) and the heating wire ( The micro-resistance is connected between 130 and senses the voltage difference between both ends and converts it to the amount of current (not shown), and compares the amount of current continuously to determine the timing of supply / discharge of battery (Batt +) power under the control of the microcomputer 90. In addition, the heating wire 130 is characterized in that the heater 120 for maintaining a constant temperature of the micro-resistance 110 is provided.
한편, 상기 비교기(180')는 상기 수온 게이지 센서(140)와 상기 외부 온도 센서(150)에서 감지된 두 센서의 온도차가 성애가 끼는 데이타 설정값과 비교되는 것을 특징으로 한다.On the other hand, the comparator 180 'is characterized in that the temperature difference between the two sensors sensed by the water temperature gauge sensor 140 and the external temperature sensor 150 is compared with the data set value of the sex.
또한, 상기 미소저항(110)은 상기 밧데리(Batt+) 전원이 열선으로 공급될 때 상기 열선(130) 앞에 설치된 상기 미소저항(110) 양단의 전압을 감지하여 이를 전류량으로 환산하여 계속 전류량의 변화를 상기 비교기(180)에서 비교하여 상기 마이콤(90)의 제어로 밧데리 전원의 공급/차단 시기를 결정하는 것을 특징으로 한다.In addition, when the battery (Batt +) power is supplied to the heating wire, the micro resistor 110 senses the voltage across the micro resistor 110 installed in front of the heating wire 130 and converts it into the amount of current to continuously change the amount of current. Compared with the comparator 180, it is characterized in that the control of the microcomputer 90 determines the supply / interruption time of the battery power.
이를 첨부도면을 참조하여 작동 상태를 보다 상세하게 설명하면 다음과 같다.Referring to the accompanying drawings in more detail the operating state as follows.
먼저, 상기 수온 게이지 센서(140)는 차안의 온도를 감지하고 상기 외부 온도 센서(150)는 차밖의 온도를 감지하여, 상기 비교기(180')에서 상기 두 센서에서 감지된 온도의 차와 성애가 끼는 데이터 설정값과 비교를 한다.First, the water temperature gauge sensor 140 detects a temperature inside the car and the external temperature sensor 150 detects a temperature outside the car, so that the difference between the temperatures detected by the two sensors in the comparator 180 ' Compare with the set data.
비교 결과, 상기 두 센서에서 감지된 온도의 차가 데이터 설정값보다 더 크게 되면, 상기 마이콤(90)은 이를 성애가 낀 것으로 판단하고 디프로스터 릴레이(100)을 구동하여 밧데리(Batt+) 전원을 열선(130)에 공급하여 성애를 제거한다.As a result of the comparison, when the difference in temperature detected by the two sensors is greater than the data set value, the microcomputer 90 determines that it is depressed and drives the defroster relay 100 to heat the battery (Batt +) power. 130 to remove the erotica.
이 때, 상기 열선(130) 앞단에 설치된 상기 미소저항(110)에서 상기 미소저항(110) 양단의 전압을 상기 비교기(180)에 입력하고 상기 비교기(180)에서 양단의 전압값을 전류량으로 환산하여 상기 전류량의 변화를 가지고 상기 마이콤(90)은 성애가 있는지 없는지를 판별하게 된다.At this time, the voltage of both ends of the micro-resistance 110 is input to the comparator 180 in the micro-resistance 110 installed at the front end of the heating wire 130, and the voltage values of both ends of the comparator 180 are converted into current amounts. Thus, the microcomputer 90 determines whether there is sexual love with the change in the amount of current.
즉, 온도가 낮으면 저항을 통과하는 전류량은 증가하게 되고 반대로 온도가 높으면 전류량은 감소하게 된다.In other words, when the temperature is low, the amount of current passing through the resistor increases. On the contrary, when the temperature is high, the amount of current decreases.
상기 마이콤(90)에서 전류량의 변화 정도로 판단하여 성애가 없다고 인식되면 상기 디프로스터 릴레이(100) 접점을 오프시켜 상기 열선(130)으로의 밧데리(Batt+) 전원 공급을 차단하여 더 이상 성애를 제거하지 않게 된다.If it is determined that the degree of change in the amount of current in the microcomputer 90 is not sexually active, turn off the defroster relay 100 contact to cut off the battery (Batt +) power supply to the heating wire 130 so as not to remove the sexual love anymore. Will not.
일반적으로 부하(실시예, 열선)에 흐르는 전류량은 그 부하의 상태, 부하 증감, 주위 환경 변화 등의 다양한 정보를 가지게 되고, 본 발명에서는 상기와 같은 정보를 이용하여 차량의 디프로스터의 효율적인 동작에 응용하고자 하는 것이다.In general, the amount of current flowing through a load (example, hot wire) has a variety of information, such as the state of the load, load increase and decrease, environmental changes, etc. In the present invention, the above information is used to effectively operate the defroster of the vehicle. It is to be applied.
본 발명의 실시예로 본 발명을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.
도 3은 본 발명의 실시예에 따른 실험예를 도시한 그래프이다.3 is a graph showing an experimental example according to an embodiment of the present invention.
디프로스터 동작시 뒷유리, 열선의 온도 증가에 의해 통전 전류는 계속 감소하게 되고 성애가 완전히 제거되는 경우에는 전류의 감소 속도는 상당히 느려지게 된다.During the defroster operation, the conduction current continues to decrease due to the increase in the temperature of the rear glass and hot wire, and the rate of decrease of the current decreases considerably when the defrost is completely removed.
도 3에서 뒷유리 열선 전류량에 따른 시스템 판단예를 보여준다.3 shows a system determination example according to the amount of rear glass hot wire current.
상기 도 3에서 ①은 가장 일반적인 경우로서 성애 제거 속도에 따라서 적당한 전류 감소량을 보이며 전류 증감이 둔화된 시점에서 디프로스터는 오프되는 것을 보여준다.In FIG. 3, ① is the most common case, and the defroster is turned off at a time when the current increase or decrease is slowed down according to the rate of defrosting.
②는 늦가을 정도의 날씨에서 성애는 많으나 감소속도가 빠르므로 외기 온도는 높지 않으므로 최종 전류량이 작아지고운행중에 재가동할 필요가 없게 된다.② in late autumn weather is a lot of sexuality, but the rate of deceleration is fast, so the outside temperature is not high, the final amount of current is small, there is no need to restart during operation.
③은 온도가 상당히 낮은 날씨를 나타내고 따라서 성애의 양은 적게 되며 상기의 조건에서는 성애가 녹아서 다시 얼어붙은 상태이고 얼마후 재가동이 필요하게 된다.③ indicates the weather is quite low temperature, therefore the amount of sex is less, and under the above conditions, the sex is melted and frozen again, and after a while, it needs to be restarted.
이상에서 본 바와 같이 본 발명은 수온센서와 외부 온도센서에서 감지된 두 온도차를 비교하여 성애가 끼는 것을 감지하여 이를 마이콤이 인식하고 디프로스터 릴레이를 작동시켜 열선에 전원을 공급하여 성애를 제거하고, 열선 앞단에 미소저항을 설치하여 상기 마이콤에서 미소저항을 지나가는 전류량을 검출하여 이 전류량의 정도를 판단하여 성애제거 완료시 디프로스터 릴레이를 오프시켜 주게 되어, 성애의 존재여부에 따라 자동으로 성애를 제거시켜주는 효과가 있다.As described above, the present invention compares the two temperature differences sensed by the water temperature sensor and the external temperature sensor, detects that the sex is stuck, recognizes this by the microcomputer, operates the defroster relay, removes the sex by supplying power to the heating wire, The micro resistor is installed in front of the heating wire to detect the amount of current passing through the micro resistor in the microcomputer to judge the degree of the amount of current, and when the defrosting is completed, the defroster relay is turned off. It is effective.
