본 발명은 유압장치의 작동유나 자동차의 엔진오일과 같이 장시간 순환 사용 하는 오일의 교환시기를 체크할 수 있는 장치에 관한 것으로, 보다 상세하게는 오일의 교환시기를 결정하는 요소인 오일의 오염도와 열화정도 및 사용시간 등을 종합적으로 점검할 수 있는 수단을 제공하는 것에 관한 것이다.The present invention relates to a device that can check the replacement time of the oil that is circulated for a long time, such as the hydraulic oil of the hydraulic system or the engine oil of the automobile, and more specifically, the pollution and deterioration of the oil which is a factor that determines the oil replacement time The present invention relates to providing a means for comprehensively checking the degree and use time.

오일의 교환주기는 통상 매뉴얼에 명기되어 있는 사용시간 또는 주행거리에 따라 실시하도록 되어 있으나, 이는 표준적인 기준일뿐 기계의 노후상태나 사용환경 등에 따라서는 오일의 오염 정도나 열화 정도에 차이가 발생하므로 사용자가 이를 감안하여 교환시기를 결정하고 있었다.The oil replacement cycle is usually performed according to the usage time or mileage specified in the manual. However, this is only a standard standard. Therefore, the degree of oil contamination or deterioration may vary depending on the age of the machine or the environment of use. The user was considering the timing of the exchange.

그러나 오일의 상태를 점검하는 것은 사용자의 경험에 의존하는 것이므로 그 상태를 정확하게 판단할 수 없어 적정교환주기를 지나쳐 기계의 내구성을 저하시키거나 필요 이상 빈번한 교환으로 부담을 가중시키는 경우가 발생하였다.However, checking the condition of oil depends on the user's experience, so it is impossible to determine the condition accurately, which results in a decrease in the durability of the machine beyond the proper replacement period or an increase in the burden by frequent replacement.

종래 오일의 교환시기를 점검하기 위한 장치로는 오일 내에 절연저항체를 중심으로 그 양측에 부착된 전극에 전원을 연결하여 저항의 변화에 의해 검출되는 전류로부터 오일의 열화 정도를 감지하여 오일교환시기를 검지하는 장치가 공지되어 있었고, 또 다른 교환시기 점검장치로는 오일탱크 외부의 감시창 양면에 설치되어 적외선을 오일의 감시창으로 발사하고 이때 수신되는 광신호를 센싱하는 오일투명도 감지부와 오일의 투명도에 따라 변하는 미소한 전기적 신호를 상기 오일 투명도 감지부로부터 입력하여 이를 일정 기준값과 비교하는 비교기와 상기 비교기의 출력신호를 디지탈 신호로 변화하는 A/D 변환기와 상기 A/D 변환기에 의해 거출된 오일의 투명도에 따라 오일의 교환시점을 사용자에게 인지시키는 알람부로 구성된 것이 실용신안 등록공고 실1994-0008117호로 공지된 바 있었다.Conventional equipment for checking the oil replacement time is to connect the power supply to the electrodes attached to both sides of the insulation resistor in the oil and detect the degree of oil deterioration from the current detected by the resistance change. The detection device is known, and another replacement time check device is installed on both sides of the monitoring window outside the oil tank, and emits infrared rays to the monitoring window of the oil and senses the optical signal received at this time. A comparator for inputting a minute electrical signal varying according to the transparency from the oil transparency detector and comparing it with a predetermined reference value and an A / D converter and an A / D converter for converting the output signal of the comparator into a digital signal are collected. The utility model consists of an alarm unit that notifies the user of the point of oil change depending on the transparency of the oil. Rock Fenugreek announcement 1994-0008117 room had been known.

그러나 상기와 같은 구성은 전류의 저항변화로 오일의 열화정도만 감지하거나 적외선의 투광도를 기준으로 오일의 오염도만 감지할 수 있을 뿐 오일의 종합적인 상태를 판단할 수 없었다.However, the above configuration can only detect the degree of deterioration of the oil by the resistance change of the current or only the degree of contamination of the oil based on the infrared light transmittance could not determine the overall state of the oil.

본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로, 오일탱크 또는 오일순환 통로상에 구비되는 오일의 열화정도를 측정할 수 있는 비저항 측정 검류계와 발광다이오드와 수광부로 구성되는 오일 오염도 측정 센서로부터 입력되는 데이터와 기계의 가동에 따른 사용시간을 적산하는 타이머 또는 주행거리계로부터의 데이터를 기초로 오일의 교환시기를 판단하는 마이크로 프로세서로 구성된다.The present invention has been made to solve the above-mentioned problems, the oil resistance measuring sensor consisting of a resistivity measuring galvanometer and a light emitting diode and a light receiving unit that can measure the degree of degradation of the oil provided on the oil tank or the oil circulation passage It is composed of a microprocessor for determining the oil replacement time based on the data input from the timer and the data from the odometer or integrating the use time according to the operation of the machine.

또한 본 발명은 측정데이터의 신뢰성을 제고할 수 있도록 오일의 열화정도 및 오염도 측정은 오일이 일정한 온도에 도달한 경우에 작동할 수 있게 구성된다.In addition, the present invention is configured to measure the degree of degradation of the oil and the degree of contamination so that the reliability of the measurement data can be operated when the oil reaches a certain temperature.

또한, 오일교환시기 점검장치로부터 출력되는 데이터는 기계장치의 오퍼레이팅 판넬 또는 자동차의 계기판에 경고등표시, 알람 또는 음성으로 출력될 수 있게 구성할 수도 있다.In addition, the data output from the oil change timing check device may be configured to be output to the operating panel of the mechanical device or the instrument panel of the vehicle as a warning light indication, an alarm or a voice.

본 발명의 바람직한 실시 예에 대하여 첨부한 도면을 참조하여 보다 상세하게 설명하기로 한다.Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명 오일 비저항 측정 검류계의 개략도이며, 도 3은 본 발명 오일 오염도 측정계의 개략도이고, 도 4는 본 발명의 회로 구성도이다.Figure 2 is a schematic diagram of the oil resistivity measurement galvanometer of the present invention, Figure 3 is a schematic diagram of the oil contamination degree measuring system of the present invention, Figure 4 is a circuit diagram of the present invention.

도 2에 도시된 바와 같이 오일 비저항 특정 검류계(10)는 절연저항체(11)와 일정거리를 이격하여 구비되는 전극(12, 12')으로 구성되고 전원(13)에 연결된다.As shown in FIG. 2, the oil resistivity-specific galvanometer 10 is composed of electrodes 12 and 12 ′ provided to be spaced apart from the insulation resistor 11 and connected to the power source 13.

오일은 통상적으로 열화가 진행됨에 따라 저항이 증가되는 특성을 가지고 있으므로 오일열화의 진행에 비례하여 검출전류가 감소한다.Since oil generally has a property of increasing resistance as the deterioration progresses, the detection current decreases in proportion to the progress of the oil deterioration.

저항에 걸리는 전압은 전류와 저항의 곱으로 표시되고 전원이 일정할 때 저항은 오일열화에 따라 변하므로 이를 검출하고 일정 기준값과 비교하면 오일의 열화정도를 측정할 수 있다.The voltage across the resistor is expressed as the product of the current and the resistance. When the power is constant, the resistance changes according to the oil deterioration. Therefore, the degree of oil deterioration can be measured by detecting it and comparing it with a predetermined reference value.

오일은 열화가 진행됨에 따라 저항이 증가되는 특성을 가지고 있으나 오일중에 불순물, 즉 금속분말이나 수분 등이 혼입될 경우 오일의 열화에도 부구하고 검출되는 전류가 증가되는 경우가 발생할 수 있다.The oil has a property of increasing resistance as the deterioration progresses, but when impurities, ie metal powder or moisture, are mixed in the oil, the oil may deteriorate and the detected current may increase.

따라서, 오일의 교환시기는 비저항계측에 의한 결과만을 기준으로 할때에는 적정교환시기를 놓칠 수 있다.Therefore, the replacement time of the oil may miss the proper replacement time when only the results of the resistivity measurement are used as a reference.

도 3의 오일오염도 측정계(21)는 레이저 다이오드(22)와 레이저 다이오드(22)에서 발광되는 빛을 수광하는 수광부(23)를 레이저 다이오드(22)로부터 일정거리를 이격하여 구비하고 전원(13)으로 연결하는 구성으로 형성된다.The oil pollution degree measuring system 21 of FIG. 3 includes a laser diode 22 and a light receiving unit 23 receiving light emitted from the laser diode 22 spaced apart from the laser diode 22 by a predetermined distance. It is formed in a configuration that connects.

레이저 다이오드(22)에서 발광되는 빛은 오일을 통과하여 수광부(23)에 도달하고 수광부(23)에 도달하는 빛의 밝기는 오일의 오염도에 따라 변하므로 빛의 밝기를 전기적 신호로 변환하고 이를 일정 기준값과 비교하여 오염도를 환산 출력한 다.The light emitted from the laser diode 22 passes through the oil to reach the light receiving unit 23 and the brightness of the light reaching the light receiving unit 23 varies depending on the contamination of the oil, thereby converting the brightness of the light into an electrical signal. Compared with the reference value, the pollution degree is converted and output.

상기 오일 비저항 측정 검류계(10)와 오일 오염도 측정계(21)는 하나의 구조로 일체화하여 컴펙트하게 할 수도 있다.The oil resistivity measuring galvanometer 10 and the oil pollution degree measuring system 21 may be integrated into one structure to make it compact.

즉, 레이저 다이오드(22)와 인접하여 하나의 전극(12)을 구비하고 일정거리를 이격하여 수광부923)와 다른 하나의 전극(12')을 구비하면 하나의 일체화된 센서로 오일의 열화정도와 오염도를 측정할 수 있다.That is, if one electrode 12 is provided adjacent to the laser diode 22 and the light receiving unit 923 and the other electrode 12 'are spaced apart from each other by a distance, the degree of deterioration of the oil may be reduced by one integrated sensor. The degree of contamination can be measured.

또한 오일의 전기저항이나 투광성은 오일의 온도에 따라 변할 수 있으므로 도시되지 않는 온도센서에 의하여 오일의 온도가 일정 기준에 도달한 경우에만 계측되게 하는 것이 바람직하다.In addition, since the electrical resistance or light transmittance of the oil may change depending on the temperature of the oil, it is preferable to measure the oil only when the temperature of the oil reaches a predetermined standard by a temperature sensor (not shown).

또한 오일의 교환주기는 오일의 열화정도 및 오염도외에 사용시간이나 주행거리와의 관계도 고려할 필요가 있으므로 일정기준의 최대 가동시간이나 최대주행거리등을 설정하여 교환주기를 결정하는 것이 바람직하다.In addition, the oil replacement cycle needs to consider the relationship between the use time and the mileage, in addition to the degree of oil deterioration and contamination, and it is desirable to determine the replacement cycle by setting the maximum operating time or the maximum driving distance according to a certain standard.

가동시간을 체크하기 위한 타이머(30)는 CNC에 내장되는 것을 이용하는 것이 가능하며 주행거리는 자동차의 계기판에 구비되는 적산 주행거리계로부터 데이터를 출력받아 이용하는 것이 바람직하다.Timer 30 for checking the operation time can be used that is built in the CNC, the mileage is preferably used to receive data from the integrated odometer provided in the instrument panel of the vehicle.

상기의 오일 교환시기에 대한 정보는 CNC장치의 오퍼레이팅 판넬이나 계기판상에 발광경고 신호나 알람 또는 음성으로 출력할 수 있게 구성하여 사용자로 하여금 오일교환시기를 최적화 하게 할 수 있다.The information on the oil change time can be configured to output the light emitting warning signal, alarm or voice on the operating panel or the instrument panel of the CNC machine to allow the user to optimize the oil change time.

이상에서 설명한 바와 같이 본 발명은 오일의 열화상태와 오염도를 간편한 구성으로 계측하고 이를 사용자에게 경고함으로써 불필요한 오일교환으로 인한 자원의 낭비를 줄일 수 있게 하고 또한 부주의로 오일교환시기를 놓쳐 장비의 내구성을 단축하게 하는 일이 발생하지 않게 하는 효과가 있다.As described above, the present invention can reduce the waste of resources due to unnecessary oil change by measuring the deterioration state and pollution degree of the oil in a simple configuration and warning the user, and also inadvertently misses the oil change time to improve the durability of the equipment. This has the effect of avoiding shortening.
