Description
본 발명은 위치제어장치에 관한 것으로서, 특히 기존의 단순한 스위치 기능을 갖는 마그네틱(magnetic) 근접스위치와는 다르게 자기센서를 위치검출구간 내에 어레이(array)로 설치하고 이동하는 물체에 자석을 부착하여 자기센서 어레이 중 온/오프(on/off) 되는 자기센서의 상태에 따라 이동물체의 현재위치 및 정지위치를 제어할 수 있도록 하는 마그네틱 비접촉 근접센서어레이를 이용한 위치제어장치에 관한 것이다.The present invention relates to a position control apparatus. In particular, unlike a conventional magnetic proximity switch having a simple switch function, a magnetic sensor is installed in an array within a position detection section and an magnet is attached to a moving object. The present invention relates to a position control apparatus using a magnetic non-contact proximity sensor array for controlling a current position and a stop position of a moving object according to a state of a magnetic sensor on / off of a sensor array.
일반적인 마그네틱(magnetic) 근접스위치는 이동하는 물체상에 자석을 설치하고 자기센서를 내장한 마그네틱스위치에서 자기센서가 자석이 접근할 때 발생하는 자장의 세기를 검출하여 자석이 자기센서에 일정거리 이상 접근하여 자장의 값이 설정치보다 커지면 온/오프 동작을 하는 단순한 기능을 갖는 것이다. 이러한 기능을 갖는 기본적인 마그네틱 근접스위치의 동작원리를 도 1에 나타냈다. 도 1에서 도면부호 1은 이동물체, 2는 자석, 3은 자기센서, 4는 전원장치, 5는 출력회로를 각각 나타낸다.A general magnetic proximity switch installs a magnet on a moving object and detects the strength of the magnetic field generated when the magnet approaches the magnetic sensor in a magnetic switch with a built-in magnetic sensor, and the magnet approaches the magnetic sensor over a certain distance. If the value of the magnetic field is larger than the set value, it has a simple function of on / off operation. The operation principle of a basic magnetic proximity switch having such a function is shown in FIG. In FIG. 1, reference numeral 1 denotes a moving object, 2 a magnet, 3 a magnetic sensor, 4 a power supply device, and 5 an output circuit.
그러나 이러한 마그네틱 근접스위치는 동작원리상 외부로 노출되어 있는 부분이 없으며 초음파 및 광센서등과 같이 검출하여야 하는 공간의 먼지, 연기와 같은 부유물 및 온도, 습도 등의 환경요인의 영향을 적게 받으므로 열악한 환경조건에서의 사용성이 높다는 장점을 갖는 것으로 실제 제철소와 같은 열악한 동작환경에서 가장 안정적인 동작을 나타내고 있으며, 기타 센서에 비해 수명이 길고 가격이 저렴하다는 특징이 있다. 그러나 종래 마그네틱 근접스위치는 동작시 정확한 위치를 검출하는 응용분야 및 위치제어를 필요로 하는 분야에서는 사용성이 떨어지는데 이는 이동 물체상에 부착된 자석에 의해 자기센서가 반응하는 방식에서 자기센서에 가장 큰 영향을 미치는 자장의 세기가 거리의 변화에 따라 선형적인 증가 또는 감소의 특성을 나타내지 못하고 지수함수적인 변화를 지니는데 기인한다.However, these magnetic proximity switches are not exposed to the outside due to the principle of operation, and are poor because they are less affected by the environmental factors such as dust, smoke, suspended matter such as dust and smoke, and temperature and humidity. It has the advantage of high usability under environmental conditions and shows the most stable operation in harsh operating environments such as steel mills. It has a long life and low price compared to other sensors. However, the conventional magnetic proximity switch has low usability in applications that require accurate position detection during operation and in areas requiring position control. This is due to the fact that the intensity of the magnetic field does not show a linear increase or decrease with the change of the distance and has an exponential change.
즉, 이동물체에 부착된 자석에서 발생하는 자장의 크기가 자기센서에 접근할수록 급격히 증가하게 되어 자기센서의 출력이 온/오프를 나타내는 시점의 예측이 어려우므로 정밀한 이동물체의 위치검출이 어렵다고 하는 문제점이 있었다.In other words, the magnitude of the magnetic field generated by the magnet attached to the moving object increases rapidly as the magnetic sensor approaches the magnetic sensor. Therefore, it is difficult to accurately detect the position of the moving object because it is difficult to predict when the output of the magnetic sensor indicates on / off. There was this.
본 발명은 상기한 실정을 감안하여 종래 마그네틱 근접스위치가 갖는 문제점을 해결하고자 발명한 것으로서, 종래 마그네틱 근접스위치와는 다르게 검출용 자기센서를 일렬로 여러개를 어레이 배치하여 블록화 하고 자기센서 각각의 출력을 검출회로와 연결하여 이동물체에 설치한 자석의 움직임에 따라 각 자기센서의 온/오프 출력을 검출하여 이동물체의 현재위치를 정확히 읽을 수 있도록 하는 마그네틱 비접촉 근접센서어레이를 이용한 위치제어장치를 제공함에 그 목적이 있다.The present invention has been invented to solve the problems of the conventional magnetic proximity switch in view of the above situation, and unlike the conventional magnetic proximity switch, a plurality of magnetic sensors for detection are arranged and arranged in a row to block the output of each magnetic sensor. Provides a position control device using a magnetic non-contact proximity sensor array that detects the on / off output of each magnetic sensor according to the movement of a magnet installed on the moving object and accurately reads the current position of the moving object by connecting to a detection circuit. The purpose is.

이하 첨부 도면을 참조하여 본 발명의 작용을 상세하게 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
도 2 및 도 3은 본 발명 마그네틱 비접촉 근접센서어레이를 이용한 위치제어장치의 구성도로서, 이러한 구성의 마그네틱 비접촉 근접센서어레이를 이용한 위치제어장치는 이동물체(1)에 설치한 자석에 근접한 자기센서(3)가 자장을 검출하여 검출된 자장의 량으로 센서온/오프검출부(13)가 온/오프상태를 검출하여 즉, 검출된 자장의 량이 일정량을 넘으면 온상태, 그렇지 않으면 오프상태로 검출하여 제어용 PC를 통해 이동물체(1)의 위치를 파악하고, 이동물체(1)의 이동을 제어하게 된다.2 and 3 is a configuration diagram of the position control device using the magnetic non-contact proximity sensor array of the present invention, the position control device using the magnetic non-contact proximity sensor array of this configuration is a magnetic sensor close to the magnet installed in the moving object (1) (3) The magnetic field is detected and the sensor on / off detection unit 13 detects the on / off state with the detected amount of magnetic field. The position of the moving object 1 is determined through the control PC, and the movement of the moving object 1 is controlled.
따라서 종래의 마그네틱 비접촉 근접센서를 이용한 위치제어장치 보다 정밀한 위치판단을 할 수 있다. 결과적으로 정지위치의 정밀한 판단이나 이동물체의 정지위치에서의 이동경향성을 판단하는데 적용할 수 있으므로 종래 하나의 자기센서로 이루어진 근접스위치의 기능을 대폭 강화 할 수 있게 된다.Therefore, it is possible to make a precise position determination than a position control apparatus using a conventional magnetic non-contact proximity sensor. As a result, it can be applied to the precise determination of the stop position or to determine the movement tendency at the stop position of the moving object, thereby greatly enhancing the function of the conventional proximity switch composed of one magnetic sensor.
이러한 마그네틱 비접촉 근접센서어레이를 이용한 위치제어장치의 기능을 보다 안정시키기 위하여 이동물체(1)가 각 자기센서(3)에 접근하는 경우와 멀어지는 경우를 판정하고 각각의 경우에 몇 개의 자기센서가 온/오프 반응을 나타내는지를 보다 손쉽게 알 수 있도록 하기 위한 구성이 도 3에 도시한 구성인 바, 이동물체(1)가 최초로 접근하게 되는 셋트/리셋트용 센서(3')에는 셋트/리셋트용 플립플롭(F0)을 연결하여 최초로 이동물체(1)의 자석(2)이 셋트/리셋트용 센서(3')에 접근할 때 셋트되고, 다시 셋트/리셋트용 센서(3')에서 자석이 멀어지는 경우에는 리셋트 되도록 구성하여 이동물체(1)의 접근시와 이탈시의 판정신호를 발생시킨다. 이후 자기센서(3) 각각의 출력에는 플립플롭(F1, F2,ㆍㆍㆍ,Fn)을 각각 연결하여 이동물체(1)가 지나가는 경우의 자기센서의 온 또는 오프상태를 판단하여 그 결과를 유지하도록 함으로써 제어용 PC(14)에서 보다 간편하게 자기센서의 검출신호로부터 이동물체(1)의 위치, 접근 및 멀어지는 상태를 정확하게 판단하여 이동물체(1)의 이동을 확실하게 제어할 수 있게 된다.In order to stabilize the function of the position control apparatus using the magnetic non-contact proximity sensor array, it is determined that the moving object 1 is far from the approach of each magnetic sensor 3, and in each case, several magnetic sensors are turned on. The configuration for making it easier to know whether the on / off reaction is shown in FIG. 3 is the set / reset sensor 3 'to which the moving object 1 first approaches. It is set when the magnet 2 of the moving object 1 approaches the set / reset sensor 3 'by first connecting the flip-flop F0, and again the magnet in the set / reset sensor 3'. In the case of a long distance, it is set so that it may reset and generate | occur | produce the determination signal at the time of approaching and leaving of the moving object 1, and so on. After that, flip-flops F1, F2, ..., Fn are respectively connected to the outputs of the magnetic sensors 3 to determine the on or off state of the magnetic sensor when the moving object 1 passes, and the result is maintained. By doing so, the control PC 14 can more accurately determine the position, approach and distance of the moving object 1 from the detection signal of the magnetic sensor so that the movement of the moving object 1 can be reliably controlled.
상기한 바와 같이 작용하는 본 발명 마그네틱 비접촉 근접센서어레이를 이용한 위치제어장치에 의하면 종래 하나의 자기센서에 의한 위치제어장치에 비해 자기센서의 내환경성 및 동작의 안정성을 유지하면서 보다 정밀한 이동물체의 위치를 파악할 수 있고, 이동물체의 정지 및 이동위치를 정밀하게 제어할 수 있는 장점이 있다.According to the position control apparatus using the magnetic non-contact proximity sensor array of the present invention that acts as described above, the position of the moving object is more precise while maintaining the environmental resistance and the stability of the operation of the magnetic sensor than the position control apparatus using the conventional one magnetic sensor. Can grasp, there is an advantage that can precisely control the stop and moving position of the moving object.
