Description

속도 모니터링을 위한 방법 및 장치{METHOD AND DEVICE FOR MONITORING SPEED}METHOD AND DEVICE FOR MONITORING SPEED}

본 발명은 철도 차량의 속도를 모니터링하기 위한 방법 및 이와 관련한 장치에 관한 것이다.The present invention relates to a method for monitoring the speed of a railway vehicle and to a related device.

대체로 속도 모니터링 장치는 철도 차량의 속도를 설정값으로 제어하고 그리고/또는 최대 허용 속도를 초과하는 경우에 강제 제동을 개시하기 위해 사용된다. 통상적으로 최대 허용 속도는 예를 들어 경사진 트랙, 작은 반경을 갖는 트랙 만곡부, 종착 트랙(dead-end track) 또는 주행 방향 변환 설비에서뿐만 아니라, 오버랩 경로가 단축된 트랙에서의 트랙별 특유의 최대 속도이다. 이를 위해, 2개의 부분 기능들, 즉 트랙측 장치에서 철도 차량의 속도 근사치의 측정 및 분석과, 속도가 너무 빠를 때 철도 차량에 대한 제동 명령의 전송이 구현될 수 있다.In general, speed monitoring devices are used to control the speed of railroad cars to a set point and / or to initiate forced braking in the event of exceeding the maximum allowable speed. Typically the maximum permissible speed is a track-specific maximum speed, for example on sloped tracks, track curvatures with small radii, dead-end tracks or direction changes, as well as on tracks with shortened overlapping paths. to be. To this end, two partial functions can be implemented: the measurement and analysis of the speed approximation of the railway vehicle in the track side device and the transmission of a braking command for the railway vehicle when the speed is too fast.

도 1에는 이러한 문제를 해결하기 위한 공지된 설계 방식의 전형적인 구성이 도시되어 있다. 이 경우, 트랙측 장치는 예를 들어 유도성으로 작용하는 결합 코일을 기초로 하거나 자기식, 전기 기계식 또는 기계식으로 작용하는 접촉부를 기초로 한 주행 정지부(1)와, 예를 들어 유도성으로 작용하는 휠 센서를 기초로 한 2개의 측정점(3 및 4)을 갖는 사전 접속된 측정 트랙(2)으로 구성되어 있다. 철도 차량(5)에는 트랙측 주행 정지부(1)를 넘어갈 때 주행 정지부의 활성화 상태 또는 비활성화 상태를 인식하는 장치(6)가 제공된다. 기본 상태에서 주행 정지부(1)는 항상 활성화되어 있고, 이에 따라 이를 넘어가는 철도 차량의 강제 제동을 유도한다. 속도의 측정 및 분석은 2개의 측정점(3 및 4)의 설정 간격과, 측정점(3 및 4)으로부터 기록된 펄스들의 검출된 시간 간격에 기초한다. 검출된 속도는 최대 허용 구간 속도와 비교되며, 주행 정지부(1)는 검출된 속도가 최대 속도보다 느리거나 같은 속도일 때에만 비활성화된다. 최대 허용 속도를 초과할 때, 주행 정지부(1)는 활성화된 상태로 유지되고, 이에 따라 철도 차량측 장치(6)와 상호 작용하며 강제 제동을 유도한다. 이러한 공지된 속도 측정 장치에서의 단점은 센서 시스템을 위한 고비용 외에, 무엇보다도 간헐적인 측정의 원리를 갖는다는 것이다.Figure 1 shows a typical configuration of a known design approach to solve this problem. In this case, the track-side device is for example a traveling stop 1 based on a coupling coil acting inductively or based on a contact acting magnetically, electromechanically or mechanically, for example inductively. It consists of a pre-connected measuring track 2 with two measuring points 3 and 4 based on the acting wheel sensor. The railway vehicle 5 is provided with an apparatus 6 for recognizing the activated state or the deactivated state of the travel stop when crossing the track side travel stop 1. In the basic state, the driving stop 1 is always activated, thereby inducing forced braking of the railway vehicle beyond it. The measurement and analysis of the velocity is based on the set interval of the two measuring points 3 and 4 and the detected time interval of the pulses recorded from the measuring points 3 and 4. The detected speed is compared with the maximum allowable section speed, and the driving stop 1 is deactivated only when the detected speed is slower than or equal to the maximum speed. When the maximum allowable speed is exceeded, the travel stop 1 remains activated, thus interacting with the railway vehicle side device 6 and inducing forced braking. A disadvantage of this known speed measuring device is that, besides the high cost for the sensor system, it has above all the principle of intermittent measurement.

본 발명의 목적은 더 간단하면서도 지속적인 속도 측정을 가능하게 하는 방법 및 장치를 제공하는 것이다.It is an object of the present invention to provide a method and apparatus which allow for simpler and more continuous speed measurement.

본원의 방법에 따라, 상기 목적은 철도 차량이 신호를 방출하고, 트랙측에서 신호의 전파 시간이 속도와 관련하여 분석되며, 분석된 신호가 철도 차량에 재전송됨으로써 달성된다.According to the method herein, this object is achieved by the railway vehicle emitting a signal, the propagation time of the signal on the track side being analyzed in relation to the speed, and the analyzed signal being retransmitted to the railway vehicle.

이를 위해 청구범위 제4항에 따른, 상기 방법을 실행하기 위한 장치는 송수신 모듈을 구비한 차량 장비 및 송수신 모듈을 구비한 트랙측 장치를 포함하며, 트랙측 장치는 차량 장비의 송수신 모듈로부터 수신된 신호의 속도 분석을 위한 분석 유닛을 포함한다.To this end, the apparatus for carrying out the method according to claim 4 comprises a vehicle equipment with a transmission / reception module and a track side apparatus with a transmission / reception module, the track-side device being received from a transmission / reception module of the vehicle equipment. An analysis unit for speed analysis of the signal.

이러한 방식으로, 많은 비용이 소모되는 종래의 트랙측 센서를 사용하지 않고도 속도 모니터링이 가능하다. 고정된 측정점 및 이와 관련한 케이블 연결부는 생략된다. 양방향 신호 전송의 가능성을 통해, 관련 케이블 연결부를 구비한 주행 정지부도 필요하지 않다. 기계적, 기후적 그리고 생물학적/화학적 환경 조건에 의해 특히 마모가 발생하기 쉬운 트랙측 구성 요소가 사실상 거의 필요하지 않다.In this way, speed monitoring is possible without using costly conventional track-side sensors. Fixed measuring points and associated cable connections are omitted. With the possibility of bidirectional signal transmission, no travel stops with associated cable connections are required. Due to mechanical, climatic and biological / chemical environmental conditions virtually fewer track-side components are required, especially those which are prone to wear.

청구범위 제2항에 따라, RFID(Radio-Frequency Identification) 신호가 방출되고 분석되며 재전송된다. 간격에 대한 수치와, 시간적 변화에 있어서 이에 따른 속도 수치를 나타내는 RFID 신호의 전파 시간은 매우 높은 정확성으로 손쉽게 검출된다. 따라서, 지속적인 속도 측정뿐만 아니라, 모니터링될 철도 차량으로의 응답 신호의 지속적인 재전송도 가능하다. 또한, 정규적인 열차 운행과 더불어, 예를 들어 비정규적으로 트랙 위에서 운행되는 건설 공사용 차량의 특수한 주행을 위해서도 RFID 차량 장비가 사용될 수 있다는 것이 장점이다. 차량 장비가 휴대 가능하게 형성됨으로써, 작은 유닛을 통해서도 동반 가능하다. 또한, 차량 장비의 휴대 가능성에 의해, 속도 초과에 대해 모니터링될 트랙 구간으로의 접근 이전에 이러한 장비를 부여하고, 이러한 트랙 구간의 끝에서 회수하거나 비활성화시킬 수도 있다. 또한, 대체 시스템(fall back)으로서 본선(main line)에서 또는 예를 들어 공사 작업에 따른 일시적 트랙 차단으로 인해 오직 한쪽 트랙만 주행할 수 있는 경우의 사용도 고려할 수 있다. 이 경우, 트랙측 장치도 위치 변화 가능하게 형성될 수 있다는 것도 장점이다. 차량측 RFID 구성 요소 및 트랙측 RFID 구성 요소의 위치 설정은 철도 차량의 RFID 송수신 모듈과 트랙의 RFID 송수신 모듈 사이의 정확한 배향이 필요 없다. 또한, RFID 구성 요소에 의한 속도 측정시의 장점은 구성 요소의 견고성 및 작은 크기이며, 이로 인해 필요에 따라 결정되는 일시적 사용이 훨씬 용이해진다.According to claim 2, a Radio-Frequency Identification (RFID) signal is emitted, analyzed and retransmitted. The propagation time of the RFID signal indicating the value for the interval and the speed value according to the change in time is easily detected with very high accuracy. Thus, not only continuous speed measurement but also continuous retransmission of the response signal to the railway vehicle to be monitored. In addition to the regular train operation, it is an advantage that RFID vehicle equipment can be used, for example, for special driving of construction vehicles that run on track irregularly. Since the vehicle equipment is formed to be portable, it can be accompanied by a small unit. In addition, due to the portability of the vehicle equipment, such equipment may be given prior to access to the track section to be monitored for overspeed and may be withdrawn or deactivated at the end of such track section. It is also conceivable to use the fall back as a fall back where only one track can travel on the main line or due to, for example, temporary track interruptions due to construction work. In this case, it is also advantageous that the track-side device can also be formed to be changeable in position. Positioning of the vehicle-side RFID component and the track-side RFID component does not require accurate orientation between the RFID transceiver module of the railway vehicle and the RFID transceiver module of the track. In addition, the advantages of the speed measurement by the RFID component are the robustness and small size of the component, which makes the temporary use determined as needed much easier.

바람직하게, 최대 허용 속도를 초과하는 경우에는 청구범위 제3항에 따라 강제 제동을 개시하는 신호가 철도 차량에 재전송된다. 속도가 너무 빠를 때만 안전상의 이유로 강제 제동이 필요하므로, 적정 속도에서는 신호 재전송이 생략될 수 있다.Preferably, when the maximum allowable speed is exceeded, a signal for initiating forced braking according to claim 3 is retransmitted to the railway vehicle. Forced braking is only necessary for safety reasons when the speed is too fast, so signal retransmission can be omitted at an appropriate speed.

본 발명은 하기에 도면에 의한 설명에서 더 상세히 설명된다.The invention is explained in more detail in the following description by the figures.

도 1은 공지된 설계 방식의 속도 모니터링 장치를 도시한 도면이다.
도 2는 본 발명에 따른 속도 모니터링 장치를 도시한 도면이다.1 is a view showing a speed monitoring device of a known design scheme.
2 is a diagram illustrating a speed monitoring apparatus according to the present invention.

도 2에서, 도 1에 도시되어 상기에 설명된 공지된 속도 모니터링 장치에서와 동일한 기계 부품들은 동일한 도면 부호로 표시되어 있다. 트랙측에서 고정 측정점[3 및 4(도 1)]을 통해 설치되고 주행 정지부[1(도 1)]와 케이블 연결된 측정 트랙[2(도 1)]이 생략된 상태가 도시되어 있다. 대신에, 트랜스폰더/리더 시스템의 송수신 모듈을 구비한 차량 장비(7)가 제공되며, 이러한 차량 장비는 트랜스폰더/리더 시스템의 송수신 모듈을 구비한 트랙측 장치(9)에 의해 수신되어 차량 속도에 대해 분석되는 RFID 신호(8)를 방출한다. 상기 분석은 신호(8)의 전파 시간으로부터 도출되는 속도가 최대 허용 속도와 비교되는 방식으로 실행된다. 이를 위해, 트랙측 장치(9)의 분석 유닛(10)이 사용된다. 최대 허용 속도를 초과하는 경우에는, 강제 제동의 개시를 위한 명령을 포함하는 RFID 응답 신호(11)가 생성되어 차량 장비(7)로 전송된다.In Fig. 2, the same mechanical parts as in the known speed monitoring apparatus shown in Fig. 1 and described above are denoted by the same reference numerals. The state where the measuring track 2 (FIG. 1) installed on the track side via fixed measuring points 3 and 4 (FIG. 1) and cabled with the travel stop 1 (FIG. 1) is shown. Instead, there is provided a vehicle equipment 7 with a transmit / receive module of a transponder / reader system, which vehicle equipment is received by a trackside device 9 with a transmit / receive module of a transponder / reader system to speed up the vehicle. Emits an RFID signal 8 which is analyzed for. The analysis is carried out in such a way that the speed derived from the propagation time of the signal 8 is compared with the maximum allowable speed. For this purpose, the analysis unit 10 of the track side device 9 is used. In the case of exceeding the maximum allowable speed, an RFID response signal 11 is generated and transmitted to the vehicle equipment 7 including a command for initiating forced braking.

현재 속도의 측정은 이러한 방식으로, 도 1에 따른 속도 모니터링 장치에서와 같이 간헐적으로만 실행되는 것이 아니라 지속적으로 실행된다. 강제 제동을 위한 명령을 철도 차량(5)에 전송하는 것도 지속적으로 실행되며, 단지 주행 정지부[1(도 1)]를 넘어갈 때만 실행되는 것이 아니다. 이에 의해, 시스템 구성 요소의 수량 축소 및 간소화와 더불어, 속도 모니터링을 위한 전체 시스템의 신뢰도도 향상된다.The measurement of the current speed is carried out in this way continuously, not only intermittently, as in the speed monitoring device according to FIG. 1. The transmission of the command for the forced braking to the railway vehicle 5 is also executed continuously, and is not executed only when crossing the driving stop 1 (FIG. 1). This improves the reliability of the overall system for speed monitoring, as well as reducing and simplifying the quantity of system components.
