본 발명은 ATS 차상장치 오동작 방지 시스템에 관한 것으로서, 보다 상세하게는, ATS 차상장치의 오동작을 방지하기 위해 차량에서 상시 발진하는 주파수와 동일하게 변주할 수 있는 장치를 오동작 발생지점에 설치하여 오동작을 방지하는 시스템 및 그를 이용한 방법에 관한 것이다.The present invention relates to an ATS onboard device malfunction prevention system. More specifically, in order to prevent a malfunction of the ATS onboard device, a device capable of shifting at the same frequency as the oscillation at all times in a vehicle is installed at the point of occurrence of a malfunction. A system for preventing and a method using the same.

철도의 선로 변에는 비상시 철도 차량의 속도를 제어하기 위해 ATS 차상장치 (ATS: Automatic Train Stop)가 구비된다. Rail tracks are equipped with ATS (Automatic Train Stop) to control the speed of rail vehicles in emergencies.

진행하는 철도차량의 속도를 제어하고 비상시에 정지를 시키는 역할을 하는 ATS차상장치는 지상자로부터 약속된 발진주파수를 수신받아 상기 발진 주파수에 따라 제한속도를 인지하고 계전기의 동작을 제어하여 차량의 속도를 제어한다.The ATS on-vehicle device, which controls the speed of the ongoing railway vehicle and stops in an emergency, receives the oscillation frequency promised by the grounder, recognizes the speed limit according to the oscillation frequency, and controls the operation of the relay to speed up the vehicle. To control.

예를 들면, 다음과 같이 차량의 속도가 제어된다. 진행시에는 98KHz의 발진주파수를 지상자로부터 수신받아 이를 인지하여 차량의 속도를 제어한다. 이와 동일한 개념으로 106KHz는 45Km/h의 제한 속도로 "주의"에 해당함을 인지하여 차량의 속도를 제어하고, 114KHz는 25Km/h의 제한 속도로 "경계"에 해당함을 인지하여 차량의 속도를 제어하며, 122KHz는 "정지"에 해당함을 인지하여 차량을 정지시킨다.For example, the speed of the vehicle is controlled as follows. In progress, it receives 98KHz oscillation frequency from the ground and recognizes it to control the speed of the vehicle. In the same concept, 106KHz controls the speed of the vehicle by recognizing that it is "attention" at the speed limit of 45Km / h, and 114KHz controls the speed of the vehicle by recognizing that it is "boundary" at the speed of 25Km / h. And 122 KHz recognizes that it corresponds to "stop" and stops the vehicle.

그러나 상기와 같은 지상자와 ATS차상장치 간의 주파수 송수신 방식에 의한 속도 제어는 각종 전력, 통신장비 설치 확대 추세로 유도장애 발생하는바, 상기 유도 장애에 의한 이상주파수가 ATS 차상장치의 오동작을 일으켜 차량이 급정거를 하게 되거나 그로 인하여 열차의 운행에 지장을 초래할 수 있다.However, the speed control by the frequency transmission / reception method between the above-mentioned ground and the ATS onboard device causes induction obstacles due to the expansion of various power and communication equipment installations, and the abnormal frequency caused by the inductive interference causes the ATS onboard device to malfunction. This can cause a sudden stop or it can interfere with the operation of the train.

상기와 같은 문제점을 해결하고자 기존 오동작 발생 개소에는 차폐 또는 필터회로를 부착하여 ATS차상장치를 개선하여 사용하고 있다. In order to solve the above problems, the existing malfunctioning point is attached to a shielding or filter circuit to improve the ATS onboard device.

그러나 오동작 발생 개소의 차폐 하는 방법은 발생원(특히 통신선로)이 다른 기기(예를 들면, 무선통신기기)에 이용되는 유용한 주파수일 경우 오동작 차폐의 목적을 넘어 정상기능까지 막아버리는 문제점과 차폐시설을 하는 비용이 많이 소요되며, 작업이 용이하지 않다는 문제점이 있다.However, the method of shielding the malfunction occurrence point is to prevent the malfunction and shielding facilities beyond the purpose of malfunction shielding when the source (especially the communication line) is a useful frequency used for other equipment (for example, wireless communication equipment). It takes a lot of money, and there is a problem that the operation is not easy.

그리고 필터회로를 구비하는 방법은 필터회로가 사용되는 각 회로에서 필터 회로의 작동이 정상적으로 작동하는가 여부에 대한 검토와 필터회로의 안정성 확인에 많은 비용과 시간이 소요된다는 문제점이 있다.In addition, the method including the filter circuit has a problem in that it takes a lot of cost and time to examine whether the operation of the filter circuit is normally operated in each circuit in which the filter circuit is used and to check the stability of the filter circuit.

이하에는 첨부한 도면을 참조하여 본 발명의 구성을 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration of the present invention.

도 1은 본 발명에 따른 ATS 차상장치 오동작 방지시스템의 개념을 설명하기 위한 개념도이다.1 is a conceptual diagram illustrating the concept of an ATS onboard device malfunction prevention system according to the present invention.

ATS 차상장치는 다변주 방식을 이용한다. 여기서 다변주 방식이라 함은 열차의 여러가지 속도를 검사하기 위해 다수의 공진주파수를 가진 지상자를 차상자가 공진시키는 방식이며, 차상자 역시 상기 다수의 공진주파수를 선별하여 수신하고 이를 이용하여 차량의 속도를 제어하는 방식을 말한다.The ATS onboard vehicle uses a multivariate system. Here, the multi-variation method is a method in which a vehicle box resonates a grounder having a plurality of resonant frequencies to check various speeds of a train, and the car box also receives and selects the plurality of resonant frequencies and uses the speed of the vehicle. Say how to control.

이러한 다변주 방식의 예를 들면, 진행시에는 98KHz의 발진주파수를 지상자로부터 수신받아 이를 인지하여 차량의 속도를 제어한다. 이와 동일한 개념으로 106KHz는 45Km/h의 제한 속도로 "주의"에 해당함을 인지하여 차량의 속도를 제어하고, 114KHz는 25Km/h의 제한 속도로 "경계"에 해당함을 인지하여 차량의 속도를 제어하며, 122KHz는 "정지"에 해당함을 인지하여 차량을 정지시킨다. 그리고 차량이 정상적으로 진행할 수 있음을 인식하는 주파수는 ATS 차상장치의 발진부에서 상시 발진하는 78KHz이다.For example, the multivariate system receives an oscillation frequency of 98 KHz from a ground person and controls the speed of the vehicle. In the same concept, 106KHz controls the speed of the vehicle by recognizing that it is "attention" at the speed limit of 45Km / h, and 114KHz controls the speed of the vehicle by recognizing that it is "boundary" at the speed of 25Km / h. And 122 KHz recognizes that it corresponds to "stop" and stops the vehicle. And the frequency that recognizes that the vehicle can proceed normally is 78KHz oscillating at the oscillator of the ATS onboard device.

이러한 ATS 차상장치를 이용함에 있어서, 도 1과 같이 선로 변에 통신케이블 등의 매설 부근에 유도장애를 일으키는 오동작 구간이 존재한다. 이러한 오동작 구간에 본 발명에 따른 오동작방지장치(100)를 설치한다. In using the ATS onboard device, there is a malfunctioning section that causes induction obstacles in the vicinity of a buried communication cable or the like as shown in FIG. 1. The malfunction prevention device 100 according to the present invention is installed in such a malfunctioning section.

이렇게 설치된 오동작방지장치(100)는 차량에 부착된 속도제어장치(200)와 기하학적으로 접근 함에 따라 상기 속도 제어장치의 발진부(201)와의 상호 작용에 의해 속도제어장치(200)의 주파수가 결정된다. 즉 상기 오동작방지장치(100)에 설정된 주파수의 영향을 받게 된다. The malfunction prevention device 100 installed as described above is geometrically approached with the speed control device 200 attached to the vehicle, and the frequency of the speed control device 200 is determined by the interaction with the oscillator 201 of the speed control device. . In other words, it is affected by the frequency set in the malfunction prevention device 100.

자세한 설명은 도 2를 참조하여 설명하기로 하고, 개략적인 동작을 설명하면, ATS차상장치는 정상적인 진행을 의미하는 정상작동 주파수인 상시 발진주파수 를 갖는바, 일반적으로 78Khz에 해당하는 주파수를 상시 발진주파수로 이용한다.A detailed description will be made with reference to FIG. 2, and when the schematic operation is described, the ATS on-vehicle device has an always oscillating frequency, which is a normal operating frequency, which means normal progress, and generally oscillates at a frequency corresponding to 78 kHz. Use it as a frequency.

따라서 오동작방지장치(100)의 주파수를 차량에서 상시 발진하고 있는 주파수인 78KHz(A)로 설정하면, 치엔원리(Ziehen's theory)에 의해 상기 속도제어장치(200)의 발진부(201)는 오동작을 일으키는 유도장애주파수(B)부근에서 치엔원리(Ziehen's theory)에 의해 상기 오동작방지장치(100)의 주파수인 78KHz(C)로 변주되어, 결국 속도제어장치는 78KHz에 해당하는 설정된 동작을 하게 된다. Therefore, when the frequency of the malfunction prevention device 100 is set to 78 KHz (A), which is a frequency that is always oscillated in a vehicle, the oscillator 201 of the speed control device 200 causes malfunction due to Ziehen's theory. In the vicinity of the induced disturbance frequency (B) is shifted to 78KHz (C), which is the frequency of the malfunction prevention device 100 by Ziehen's theory, and eventually the speed controller performs a set operation corresponding to 78KHz.

상기 치엔원리라 함은 원래의 발진주파수를 공진주파수를 가진 회로에 결합시키면 발진주파수가 공진주파수에 가까운 값으로 변화하는 것을 말한다.The chien won means that when the original oscillation frequency is coupled to a circuit having a resonance frequency, the oscillation frequency changes to a value close to the resonance frequency.

그리고 상기 78KHz에 해당되는 설정된 동작은 차량에서 상시 발진하는 주파수와 동일하며, 이는 차량이 현재 정상적으로 진행할 수 있음을 의미한다.And the set operation corresponding to the 78KHz is the same as the frequency that is always started in the vehicle, which means that the vehicle can proceed normally now.

도 2는 본 발명에 따른 ATS 차상장치 오동작 방지시스템의 구성요소를 보다 자세히 설명하기 위한 블럭도이다.2 is a block diagram illustrating in more detail the components of the ATS onboard apparatus malfunction prevention system according to the present invention.

오동작방지장치(100)는 코일과 콘덴서의 조합으로 이루어진 공진회로를 이용한다.The malfunction prevention apparatus 100 uses a resonance circuit composed of a combination of a coil and a capacitor.

상기 공진회로는 동조회로라고도 하며, 코일과 콘덴서로 된 전기회로에서는 코일과 콘덴서의 값으로 결정되는 특정 주파수에서 전기적으로 공명하고, 코일과 콘덴서의 전기적 성질이 외관상 소멸하여 약간의 양자 고유 전기저항분만의 회로가 된다. The resonant circuit is also referred to as a tuning circuit. In an electric circuit consisting of a coil and a condenser, the resonance is electrically resonated at a specific frequency determined by the values of the coil and the condenser, and the electrical properties of the coil and the condenser disappear. Becomes the circuit of.

보통은 콘덴서의 정전 에너지와 인덕턴스의 전자기 에너지가 자유로이 변환될 수 있도록 이어진 회로를 말하며, C 와 L이 직렬접속된 직렬공진회로와 이들이 병렬접속된 병렬공진회로가 기본이 된다. Usually, it refers to a circuit that can be freely converted between the electrostatic energy of the capacitor and the electromagnetic energy of the inductance, and is based on a series resonant circuit in which C and L are connected in series, and a parallel resonant circuit in which they are connected in parallel.

본 발명에서는 병렬공진회로를 이용하며, 공진주파수 f0는 다음의 수학식1 과 같다. In the present invention, a parallel resonant circuit is used, and the resonance frequency f 0 is expressed by the following Equation 1.

상기 수학식 1에서 단위 L은 H(헨리), C는 F(패럿), π는 상수이다. In Equation 1, the unit L is H (Henry), C is F (farad), and π is a constant.

본 발명에서의 오동작방지장치(100)의 공진주파수 f0는 상시 발진주파수와 동일한 78KHz가 되도록 설정한다.The resonance frequency f 0 of the malfunction prevention device 100 in the present invention is set to be 78 KHz equal to the regular oscillation frequency.

발진부(201)는 오실레이터와 증폭소자 및 피드백을 이용하는 일반적으로 발진회로를 이용함으로써, 특정한 주파수의 전류만이 회로에 흐르게 한 것이다. The oscillator 201 generally uses an oscillator circuit using an oscillator, an amplification element, and feedback, so that only a current of a specific frequency flows in the circuit.

본 발명에서는 히스테리시스 특성을 이용한 발진회로를 이용하며, 발진 주파수는 ＣＲ의 값과 사용되는 소자의 히스테리시스 특성에 따라 결정된다. In the present invention, the oscillation circuit using the hysteresis characteristics is used, and the oscillation frequency is determined according to the value of the CR and the hysteresis characteristics of the device used.

상기 발진부(201)에서는 ATS차상장치에 상시 발진주파수를 공급하여 차량이 정상운행 중임 인지하도록 하며, 상기 오동작방지장치(100)와 기하학적으로 접근함 에 따라 치엔원리에 의해 상기 오동작방지장치(100)가 갖는 공진주파수로 변주된다.The oscillation unit 201 supplies the oscillation frequency at all times to the ATS on-vehicle device to recognize that the vehicle is in normal operation. As the geometry approaches the malfunction prevention device 100, the malfunction prevention device 100 is controlled by the Chien principle. Is shifted to the resonance frequency of

필터부(203)는 상기 발진부(201)로부터의 변주된 주파수신호에 잡음(노이즈)을 제거하는 역할을 한다. 일반적으로 사용되는 노이즈필터를 이용하면 되므로 자세한 설명은 생략하기로 한다.The filter unit 203 removes noise (noise) from the shifted frequency signal from the oscillator 201. Since a noise filter generally used may be used, a detailed description thereof will be omitted.

속도조사부(205)는 상기 필터부(203)에서 제공되는 주파수 신호를 이용하여, 주파수신호에 대응되는 기 설정된 속도를 메모리로부터 독출하여 매칭시키고, 그에 해당되는 계전기를 작동시킨다. 상기 계전기는 계전기부(207)에 병렬로 구비된다.The speed research unit 205 reads and matches a predetermined speed corresponding to the frequency signal from the memory using the frequency signal provided from the filter unit 203, and operates the corresponding relay. The relay is provided in parallel with the relay unit 207.

계전기부(207)는 전기적 접점을 이용하는 스위칭 소자를 포함하여 구성되며, 주파수에 해당되는 속도를 차량의 모터 속도를 제어하는 역할을 한다. The relay unit 207 is configured to include a switching element using an electrical contact, and serves to control the motor speed of the vehicle speed corresponding to the frequency.

It receives an input (S301).

다음으로 상기 차상자에 입력된 상기 공진주파수에 해당되는 주파수로 발진주파수가 치엔현상에 의하여 변주된다(S303).Next, the oscillation frequency is varied by the Chien phenomenon at a frequency corresponding to the resonance frequency input to the vehicle box (S303).

그리고 상기 변주된 주파수를 이용하여 그에 해당되는 설정된 동작을 하도록차량의 속도를 감시하는 동작을 수행한다(S305).In operation S305, the speed of the vehicle is monitored to perform the set operation corresponding to the shifted frequency.

상기와 같은 과정을 거치면, 결국 상시 발진주파수와 동일한 주파수로 변주된 주파수에 해당되는 동작을 하므로, 오동작 개소를 통과하는 차량은 정상적인 진행을 하게 된다.After the process as described above, since the operation corresponding to the frequency shifted to the same frequency as the usual oscillation frequency, the vehicle passing through the malfunctioning point will normally proceed.
