That is, when the main engine is not moving, the alternator 102 is operated to generate electricity. For example, when the battery voltage value sensed by the controller 202 falls below a set voltage value (that is, the battery voltage is constant due to an electric device or natural discharge that is normally used). When the voltage falls below the voltage) is operated under the control of the control unit 202, the battery 104 is charged by the electricity generated by the alternator 102 according to the operation to set the voltage value of the battery 104 When the voltage rises above the value, the operation is stopped under the control of the controller 202.
제어부(202)는 전압 체커(voltage checker)로 상기 배터리(104)의 전압을 감지하고, 상기 감지한 배터리(104) 전압 값과 설정 전압 값을 비교하여 상기 배터리(104)의 전압 값이 설정 전압 값 이하로 떨어지게 된 경우 상기 스위치(201)를 오프(OFF) 시키고 더불어 상기 서브 엔진(203)을 작동시켜 배터리(104) 방전을 방지하고, 상기 서브 엔진(203)의 작동에 따라 상기 알터네이터(102)에서 발생시킨 전기에 의해 상기 배터리(104)가 충전되어 상기 배터리(104)의 전압 값이 설정 전압 값 이상 상승하게 된 경우 상기 서브 엔진(203)의 작동을 정지시키는 것이다.The controller 202 senses the voltage of the battery 104 with a voltage checker, compares the detected battery 104 voltage value with a set voltage value, and sets the voltage value of the battery 104 to a set voltage. When the value falls below the value, the switch 201 is turned off and the sub-engine 203 is operated to prevent the battery 104 from being discharged, and the alternator 102 is operated according to the operation of the sub-engine 203. When the battery 104 is charged by the electricity generated by the battery and the voltage value of the battery 104 rises above the set voltage value, the operation of the sub-engine 203 is stopped.
이하, 도 1의 본 발명에 따른 건설 기계의 배터리 방전 방지 시스템의 동작을 설명한다.Hereinafter, the operation of the battery discharge prevention system of the construction machine according to the present invention of FIG.
참고로, 본 발명은 메인 엔진 풀리(101)에 의해 작동되는 알터네이터(102)를 독립적으로 작동시킬 수 있는 서브 엔진(203)을 이용해, 메인 엔진 정지시 배터리(104)를 재충전함으로써, 메인 엔진 미 기동시 또는 장비의 장시간 방치시 생길 수 있는 배터리(104)의 방전을 방지하고, 배터리(104)의 전압을 지속적으로 일정 전압 이상 유지할 수 있는 것이다.For reference, the present invention recharges the battery 104 when the main engine is stopped by using the sub-engine 203 capable of independently operating the alternator 102 operated by the main engine pulley 101. It is possible to prevent the discharge of the battery 104, which may occur during start-up or when the equipment is left for a long time, and the voltage of the battery 104 may be continuously maintained above a certain voltage.
즉, 메인 엔진이 정지되고, 배터리(104)의 전압이 일정 전압 이하로 떨어지게 된 경우, 배터리(104)에서 부하(103)로 흐르는 전기를 차단함과 더불어 상기 서브 엔진(203)을 작동시켜 배터리(104)를 재충전함으로써, 메인 엔진 미 기동시 또는 장비의 장시간 방치시 생길 수 있는 배터리(104)의 방전을 방지하고, 배터리(104)의 전압을 지속적으로 일정 전압 이상 유지할 수 있는 것이다.That is, when the main engine is stopped and the voltage of the battery 104 falls below a predetermined voltage, the battery 104 is interrupted and the sub engine 203 is operated to cut off the electricity flowing from the battery 103 to the load 103. By recharging 104, it is possible to prevent the discharge of the battery 104, which may occur when the main engine is not started or the equipment is left for a long time, and the voltage of the battery 104 can be continuously maintained above a certain voltage.
구체적인 동작은 다음과 같다.The specific operation is as follows.
먼저, 제어부(202)는 전압 체커(voltage checker)로 배터리(104)의 전압을 감지한다. First, the controller 202 senses the voltage of the battery 104 with a voltage checker.
다음, 상기 감지한 배터리(104) 전압 값과 설정 전압 값을 비교한다. Next, the detected battery 104 voltage value and the set voltage value are compared.
상기 비교 결과, 상기 감지한 배터리(104)의 전압 값이 설정 전압 값 이하로 떨어지게 된 경우(즉, 상시로 사용되는 전기장치 또는 자연적인 방전에 의해 배터리 전압이 일정 전압 이하로 떨어지게 된 경우), 상기 배터리(104)에서 부하로 흐르는 전기를 단속하는 스위치(201)를 오프(OFF) 시킨다.As a result of the comparison, when the detected voltage value of the battery 104 falls below a set voltage value (that is, when the battery voltage falls below a certain voltage by an electric device or a natural discharge that is always used), The switch 201 for interrupting electricity flowing from the battery 104 to the load is turned off.
그리고, 더불어 서브 엔진(203)의 작동을 개시시킨다.Then, the operation of the sub engine 203 is started.
즉, 메인 엔진이 움직이지 않을 때, 알터네이터(102)를 독립적으로 작동시키는 서브 엔진(203)의 작동을 개시시킨다. That is, when the main engine is not moving, the operation of the sub-engine 203 for independently operating the alternator 102 is started.
그러면, 상기 스위치(201)는 상기 제어부(202)의 제어하에 오프(OFF) 되어 상기 배터리(104)에서 부하(103)로 흐르는 전기를 차단시키게 된다.Then, the switch 201 is turned off under the control of the controller 202 to cut off the electricity flowing from the battery 104 to the load 103.
그리고, 상기 서브 엔진(203)의 작동에 의해 상기 알터네이터(102)가 전기를 발생시켜 배터리(104)를 충전시키게 된다.In addition, the alternator 102 generates electricity to charge the battery 104 by the operation of the sub-engine 203.
그렇게 하여, 배터리(104)의 방전을 방지하게 된다.In this way, discharge of the battery 104 is prevented.
즉, 메인 엔진 미 기동시 또는 장비의 장시간 방치시 생길 수 있는 배터리(104)의 방전을 방지하게 된다.That is, the discharge of the battery 104 may be prevented when the main engine is not started or when the equipment is left for a long time.
상기 스위치(201)는 상기 배터리(104)와 상기 부하(Load)(103) 사이에 설치되어 상기 제어부(202)의 제어하에 온(ON) 또는 오프(OFF) 되어 상기 배터리(104)에서 부하(103)로 흐르는 전기를 단속하는 것이다. The switch 201 is installed between the battery 104 and the load 103 to be turned on or off under the control of the controller 202 so that the load from the battery 104 It is to control the electricity flowing to 103).
그리고, 상기 서브 엔진(203)은 상기 메인 엔진 정지시, 상기 메인 엔진 풀리(101)에 의해 작동되는 상기 알터네이터(102)를 독립적으로 작동시키는 미니(mini) 엔진이다. In addition, the sub-engine 203 is a mini engine that independently operates the alternator 102 operated by the main engine pulley 101 when the main engine is stopped.
한편, 상기 서브 엔진(203)의 작동에 따라 상기 알터네이터(102)에서 발생시킨 전기에 의해 배터리(104)가 충전되게 된다.Meanwhile, the battery 104 is charged by electricity generated by the alternator 102 according to the operation of the sub engine 203.
이때, 상기 제어부(202)는 이렇게 충전되는 배터리(104)의 전압을 감지하여, 감지한 배터리(104)의 전압 값이 설정 전압 값 이상 상승하게 된 경우 상기 서브 엔진(202)의 작동을 정지시킨다.At this time, the controller 202 detects the voltage of the battery 104 thus charged, and stops the operation of the sub-engine 202 when the detected voltage value of the battery 104 rises above the set voltage value. .
그러면, 서브 엔진(203)은 상기 제어부(202)의 제어하에 작동이 정지된다.Then, the sub engine 203 is stopped under the control of the control unit 202.
즉, 상기 제어부(202)의 제어하에 상기 배터리(104)의 전압 값이 설정 전압 값 이상 상승하게 된 경우, 작동이 정지된다.That is, when the voltage value of the battery 104 rises above the set voltage value under the control of the controller 202, the operation is stopped.
그 결과, 배터리(104)의 전압을 지속적으로 일정 전압 이상 유지할 수 있게 된다.As a result, the voltage of the battery 104 can be continuously maintained above a certain voltage.
그로 인해, 배터리의 방전에 따른 재시동 불가를 방지하고, 배터리의 교체 주기를 늘려주는 효과를 가져 오게 된다. As a result, it is possible to prevent restart due to the discharge of the battery and to increase the replacement cycle of the battery.
이상과 같이, 본 발명은 메인 엔진 풀리에 의해 작동되는 알터네이터를 독립적으로 작동시킬 수 있는 서브 엔진을 이용해, 메인 엔진 정지시 배터리를 재충전함으로써, 메인 엔진 미 기동시 또는 장비의 장시간 방치시 생길 수 있는 배터리의 방전을 방지하고, 배터리의 전압을 지속적으로 일정 전압 이상 유지할 수 있게 된다.As described above, the present invention may occur when the main engine is not started or when the equipment is left for a long time by recharging the battery when the main engine is stopped using a sub-engine capable of independently operating the alternator operated by the main engine pulley. The battery can be prevented from being discharged and the voltage of the battery can be continuously maintained above a certain voltage.
즉, 메인 엔진이 정지되고, 배터리의 전압이 일정 전압 이하로 떨어지게 된 경우, 배터리에서 부하로 흐르는 전기를 차단함과 더불어 상기 서브 엔진을 작동시켜 배터리를 재충전함으로써, 메인 엔진 미 기동시 또는 장비의 장시간 방치시 생길 수 있는 배터리의 방전을 방지하고, 배터리의 전압을 지속적으로 일정 전압 이상 유지할 수 있게 된다.That is, when the main engine is stopped and the voltage of the battery falls below a certain voltage, the electricity flowing from the battery to the load is cut off, and the sub engine is operated to recharge the battery. It prevents the discharge of the battery that can occur when left for a long time, and the voltage of the battery can be continuously maintained above a certain voltage.
