Description

지자기 센서{Terrestrial Magnetism Sensor} Geomagnetic Sensors {Terrestrial Magnetism Sensor}

본 발명은 지자기 센서에 관한 것으로, 더욱 상세하게는 안정화되고 정확한 피씨비(PCB : Printed Circuit Board) 패턴(Pattern) 방식으로 지자기 센서를 구현한 것으로서, 센서의 회전에 따른 반응속도 및 정확도를 높이고, 미소 전압의 변동을 증폭시켜 감지함으로써 감지능력을 상승시키며, 패턴방식에 의한 전자적인 검지방식으로 인해 기계적인 마모가 없어 불량률을 감소시키고, 패턴 방식으로 인한 생산이 자동화가 가능하여 생산성을 향상시키도록 한 것이다.The present invention relates to a geomagnetic sensor, and more particularly, to implementing a geomagnetic sensor in a stabilized and accurate PCB pattern (PCB) pattern method, to increase the reaction speed and accuracy according to the rotation of the sensor, Amplification of voltage fluctuation increases the detection capability, and the electronic detection method by the pattern method reduces mechanical failure due to the absence of mechanical wear, and the production by the pattern method can be automated to improve productivity. will be.

일반적으로, 항공기나 선박 등에 적용되는 항법시스템에서, 가장 중요한 것 중에 하나가 해당 항공기 또는 선박의 위치를 결정하는 것이며, 이러한 위치 결정을 위해 3군데 이상의 전파원으로부터 신호를 수신받아 전파의 도달 시간 등을 측정하여 위치를 결정하게 된다.In general, in the navigation system applied to an aircraft or a vessel, one of the most important is to determine the position of the aircraft or vessel, and to receive the signal from three or more radio sources to determine the position, the arrival time of the radio wave, etc. The position is determined by measuring.

여기서, 상기한 전파원으로는 가장 널리 알려진 지피에스(GPS : Global Positioning System)용 인공위성이 있으며, 상기 지피에스위성으로부터 전송되는 전파를 수신하는 수신기를 이용하여 위치를 결정하게 된다.Here, the radio wave source is the most widely known satellite for GPS (GPS), the position is determined by using a receiver for receiving the radio wave transmitted from the GPS satellite.

최근 들어, 상기와 같은 위치결정방법을 적용한 차량항법시스템(CNS : Car Navigation System)이 개발되어 보급되고 있으며, 위치결정을 위한 전파원으로부터 전송되는 전파를 수신하는 수신기가 차량에 탑재되어 있으며, 차량의 진행방향을 감지하는 지자기 센서 등의 부가적인 센서들을 추가로 탑재하여 차량항법시스템을 운용하고 있다.Recently, a car navigation system (CNS: Car Navigation System) applying the above positioning method has been developed and spread, and a receiver that receives radio waves transmitted from a radio source for positioning is mounted on a vehicle. The vehicle navigation system is operated by additionally installing additional sensors such as a geomagnetic sensor that detects the direction of travel.

여기서, 상기 지자기 센서는 도 3에 나타난 바와 같이, 강자성체인 링코어(Ring Core)(54)를 따라 드라이브코일(Drive Coil)(53)이 감겨져 있으며, 상기 링코어(54)의 중심에서 직교하는 엑스코일(X-coil)(51) 및 와이코일(Y-coil)(52)이 감겨져 구성된다.As shown in FIG. 3, the geomagnetic sensor has a drive coil 53 wound around a ring core 54, which is a ferromagnetic material, and is orthogonal to the center of the ring core 54. The X-coil 51 and the Y-coil 52 are wound.

상기한 구성에 의한 지자기 센서의 동작원리를 설명하면, 드라이브코일(53)에 전압을 인가하여 링코어(54)에 자력선을 발생시키면, 상기 링코어(54)에 발생되는 자력과 지자기가 합성된 유도전압이 엑스코일(51) 및 와이코일(52)을 통해 측정되며, 상기 측정되는 유도전압의 전위차에 의해 방향을 감지한다.Referring to the operation principle of the geomagnetic sensor according to the above configuration, if a magnetic force line is generated in the ring core 54 by applying a voltage to the drive coil 53, the magnetic force and geomagnetic generated in the ring core 54 is synthesized. Induced voltage is measured through the X coil 51 and the Wei coil 52, and senses the direction by the potential difference of the measured induced voltage.

그러나 상기와 같은 코일형 지자기 센서는 차량이 회전할 경우 그 방향을 감지하는 반응시간이 느리고, 엑스코일(51) 및 와이코일(52)의 직교율 오차로 인하여 감지 능력이 떨어지며, 사용되는 코일의 선경(두께)을 일정하게 유지시키지 못할 경우 지자기의 측정량이 달라짐으로써, 정확도가 떨어지게 되어 불량률이 높아지며, 코일의 사용으로 인하여 생산성이 저하되는 문제점이 있었다.However, the coil-type geomagnetic sensor as described above has a slow response time for detecting the direction when the vehicle rotates, and has a poor sensing capability due to the orthogonal error of the X-coil 51 and the Y-coil 52. If the wire diameter (thickness) is not kept constant, the measurement amount of the geomagnetism is changed, the accuracy is lowered, the defect rate is increased, there is a problem that the productivity is reduced due to the use of the coil.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점들을 해결하기 위한 것으로, 안정화되고 정확한 피씨비(PCB : Printed Circuit Board) 패턴(Pattern) 방식으로 지자기 센서를 구현함으로써, 센서의 회전에 따른 반응속도 및 정확도를 높이고, 미소 전압의 변동을 증폭시켜 감지함으로써 감지능력을 상승시킬 수 있는 지자기 센서를 제공함에 있다. Accordingly, an object of the present invention is to solve the conventional problems as described above, by implementing a geomagnetic sensor in a stabilized and accurate PCB pattern (PCB) pattern (Pattern) method, the reaction speed and accuracy according to the rotation of the sensor It is to provide a geomagnetic sensor that can increase the detection ability by increasing the detection, amplifying the fluctuation of the minute voltage.
