Abstract

케이블공기압력감시주장치의 펄스신호와 감지기의 구동을 위한 원격급전 전압이 모국정합장치로 입력되면, 모국정합장치에서는 원격급전을 차단하고 펄스신호를 톤신호로 변환하여 이/엠유니트의 음성신호정합부로 송출하거나, 다른 구현 방법으로 펄스신호를 직접 이/엠유니트의 이/엠신호정합부로 송출한다.When the pulse signal of the cable air pressure monitoring device and the remote feed voltage for driving the detector are input to the mother station matching device, the mother station stops remote feeding and converts the pulse signal into a tone signal to match the voice signal of the E / M unit. Or a pulse signal directly to the E / M signal matching unit of the E / M unit.

이/엠유니트에 입력된 톤신호 또는 펄스신호는 피씨엠전송장비에서 피씨엠 신호로 다중화되어 송출되며, 피씨엠 신호는 다시 광다중화장치에서 광신호로 다중화되어 광선로를 거쳐 자국으로 전송된다. 자국의 광다중화장치에 입력된 광신호는 광다중화장치 내에서 역다중화되어 피씨엠 신호로 피씨엠전송장비에 입력되며, 피씨엠전송장비내에서 역다중화 되어 이/엠유니트를 통해 톤신호 또는 펄스신호로 복원되며, 자국정합장치에서는 다시 원격급전을 위한 회로를 구동하며 톤신호를 펄스신호로 다시 변환하거나, 펄스신호는 직접 감지기로 송출한다.The tone signal or pulse signal input to the E / M unit is multiplexed and transmitted to the PCM signal from the PC transmission equipment, and the PCM signal is multiplexed into the optical signal in the optical multiplexing device and transmitted to the local station through the optical path. The optical signal inputted to the optical multiplexer of the local station is demultiplexed in the optical multiplexer and input to the PCM transmission device as a PCM signal, and is demultiplexed in the PCM transmission device and is de-multiplexed in the PCM transmission device. It is restored to the signal, and the local matching device drives the circuit for remote power supply again and converts the tone signal back into the pulse signal or sends the pulse signal directly to the detector.

자국의 감지기로부터 모국의 케이블공기압력감시주장치까지의 케이블공기압력감시의 결과보고는 이의 역과정을 실행한다.The reporting of the results of the cable air pressure monitoring from the local station's detector to the cable air pressure monitoring unit in the home country carries out the reverse process.

본 고안은 모국과 자국의 각 국에 모국정합장치 및 자국정합장치를 새로이 설치하여 광선로를 이용할 수 있는 케이블공기압력감시주장치의 운용에 관한 것으로서, 보다 상세하게는 모국의 케이블공기압력감시주장치와 자국에 수용된 케이블루트 내의 감지기 간의 명령과 보고 등의 데이터의 송수신을 실선의 매체를 이용하지 않고, 광선로를 이용하여 케이블공기압력감시를 위한 데이터를 송수신할 수 있도록 광다중화장치 또는 피씨엠전송장비의 이/엠유니트에 정합 할 수 있는 모국정합장치 및 자국정합장치에 관한 것이다.The present invention relates to the operation of the cable air pressure monitoring device that can use the optical fiber by newly installing the home matching device and the local matching device in the home country and each country. More specifically, the cable air pressure monitoring device and the home country of the home country The data of the optical multiplexing device or PCM transmission equipment can transmit and receive data such as command and report between the sensors in the cable route, which are received in the cable route, without using the medium of a solid line, but transmit and receive data for monitoring the cable air pressure by using the optical fiber. It relates to the mother station matching device and the self matching device that can be matched with the M / M unit.

일반적으로, 자국의 케이블루트내의 케이블공기압력을 감시하기 위하여 종래의 케이블공기압력감시주장치의 운용 구성은 도 1에 도시한 바와 같이, 케이블공기압력감시주장치(2)에서 모국(1)내의 엠디에프(MDF)(3)까지 실선으로 연결되고, 다시 모국(1)의 엠디에프(3)에서 자국(5)내의 엠디에프(6)까지 실선(4)으로 연결되며, 자국(5)의 엠디에프(6)에서 케이블루트(8) 내에 내장된 감지기(7)들의 선로들이 실선 병렬방식으로 연결되어 운용되고 있다. 이와 같이, 종래의 케이블공기압력감시주장치(2)와 감지기(7)까지의 모든 구간은 실선으로 연결되어 운용되고 있다.In general, the operation configuration of the conventional cable air pressure monitoring device for monitoring the cable air pressure in the cable route of its own country is shown in FIG. 1, in the cable air pressure monitoring device 2, the MFC in the mother station (1). (MDF) (3) is connected by a solid line, and from the MDF (3) of the mother station (1) to the MDF (6) in the mark (5) is connected by the solid line (4), the MDF of the mark (5) In (6), the lines of the sensors 7 embedded in the cable route 8 are connected and operated in a solid line parallel manner. In this way, all sections from the conventional cable air pressure monitoring apparatus 2 and the detector 7 are connected by a solid line and operated.

따라서, 모국(1)과 자국(5)간의 광선로화로 인하여 실선(4)을 광선로(17)로 대체하면 종래의 케이블공기압력감시주장치(2)는 자국(5)의 케이블루트(8) 내의 케이블공기압력을 감시할 수 있는 데이터를 송수신하는 전달 매체의 단절로 인하여 도면에 나타낸 바와 같이, 종래의 운용 구성도로는 케이블공기압력을 감시 할 수 없는 실정이다.Therefore, when the solid line 4 is replaced with the light path 17 due to the light path between the mother station 1 and the track 5, the conventional cable air pressure monitoring device 2 is in the cable route 8 of the track 5. Due to the disconnection of the transmission medium for transmitting and receiving data capable of monitoring the cable air pressure, as shown in the drawings, the cable air pressure cannot be monitored in the conventional operation configuration diagram.

본 고안은 상기 종래 기술의 문제점을 감안하여 이루어 진 것으로서, 본 고안의 목적은 모국과 자국의 실선구간이 광선로로 대체되어도, 모국의 케이블공기압력감시주장치와 자국의 케이블루트 내의 감지기와의 정상적인 운용환경을 제공함을 목적으로 한다.The present invention has been made in view of the problems of the prior art, and the object of the present invention is to operate the cable air pressure monitoring device of the home country and the sensor in the cable route of the home country even if the solid line section of the home country and the country is replaced by the optical path. To provide an environment.

상기 본 고안의 목적을 달성하기 위하여, 본 고안에서는 모국과 자국의 실선구간의 광선로 대체시 모국정합장치 및 자국정합장치를 새로이 추가 설치한다.In order to achieve the object of the present invention, in the present invention, when replacing the light beam between the mother line and the country's solid line, the mother station matching device and the national matching device are newly installed.

도 1은 종래의 케이블공기압력감시주장치의 운용구성도.1 is a configuration diagram of a conventional cable air pressure monitoring apparatus.

도 2는 본 고안에 따른 케이블공기압력감시주장치의 운용구성도.2 is an operational configuration of the cable air pressure monitoring apparatus according to the present invention.

도 3은 본 고안의 실시예에 따른 세부 구조도.3 is a detailed structural diagram according to an embodiment of the present invention.

이하, 본 고안의 바람직한 실시예를 도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

본 고안의 구성에 대해서 광선로(17)를 이용하여 케이블공기압력감시를 위한 데이터의 송수신하는 과정을 도 2에 따라 설명하면, 케이블공기압력감시주장치(2)의 펄스신호와 감지기(7)의 구동을 위한 원격급전 전압이 모국정합장치(9)로 입력되면, 모국정합장치(9)에서는 원격급전을 차단하고 펄스신호를 톤신호로 변환하여 이/엠 유니트(11)의 음성신호정합부로 송출하거나, 다른 구현 방법으로 펄스신호를 직접 이/엠유니트(11)의 이/엠신호정합부로 송출한다. 이/엠유니트(11)에 입력된 톤신호 또는 펄스신호는 피씨엠전송장비(10)에서 피씨엠 신호로 다중화되어 송출되며, 피씨엠 신호는 다시 광다중화장치(12)에서 광신호로 다중화되어 광선로(17)를 거쳐 자국(5)으로 전송된다. 자국(5)의 광다중화장치(13)에 입력된 광신호는 광다중화장치(13)내에서 역다중화되어 피씨엠 신호로 피씨엠전송장비(15)에 입력되며, 피씨엠전송장비(15)내에서 역다중화 되어 이/엠유니트(14)를 통해 톤신호 또는 펄스신호로 복원되며, 자국정합장치(16)에서는 다시 원격급전을 위한 회로를 구동하며 톤신호를 펄스신호로 다시 변환하거나, 펄스신호는 직접 감지기(7)로 송출한다. 자국(5)의 감지기(7)로부터 모국(1)의 케이블공기압력감시주장치(2)까지의 케이블공기압력감시의 결과보고는 이의 역과정을 실행한다.The process of transmitting and receiving data for the cable air pressure monitoring using the optical path 17 with respect to the configuration of the present invention will be described with reference to FIG. 2, the pulse signal of the cable air pressure monitoring main apparatus 2 and the detector 7 When the remote power supply voltage for driving is input to the mother station matching device 9, the mother station matching device 9 cuts off the remote power supply, converts the pulse signal into a tone signal, and sends it to the voice signal matching unit of the E / M unit 11. Alternatively, the pulse signal is directly sent to the E / M signal matching unit of the E / M unit 11 by another implementation method. The tone signal or pulse signal input to the E / M unit 11 is multiplexed and transmitted to the PC signal from the PC transmission device 10, and the PC signal is multiplexed into an optical signal by the optical multiplexer 12 again. It is transmitted to the mark 5 via the optical path 17. The optical signal input to the optical multiplexing device 13 of the mark 5 is demultiplexed in the optical multiplexing device 13 and input to the PCM transmission equipment 15 as a PCM signal, and the PCM transmission equipment 15 It is demultiplexed within and restored to tone signal or pulse signal through E / M unit 14, and local matching device 16 drives circuit for remote power supply again and converts tone signal back into pulse signal, or pulses. The signal is sent directly to the detector (7). The result report of the cable air pressure monitoring from the sensor 7 of the station 5 to the cable air pressure monitoring host 2 of the mother station 1 performs the reverse process thereof.

이와 같이, 간단하고 저렴하게 구현되는 모국정합장치(9)와 자국정합장치(16)를 부가 설치함으로써 광선로를 이용한 케이블 공기압력감시주장치(2)의 운용환경을 경제적으로 개선할 수 있다.In this way, the operation environment of the cable air pressure monitoring apparatus 2 using the optical path can be economically improved by additionally installing the mother station matching device 9 and the local matching device 16 which are simply and inexpensively implemented.

모국정합장치(9)와 자국정합장치(16)에 대해 좀더 자세히 도 3에 따라 설명하면, 모국정합장치(9)에서는 케이블공기압력감시주장치 정합부(18)로 입력되는 펄스신호와 원격급전을 원격급전제어부(19)에서 원격급전을 차단하고 펄스신호만을 신호처리부(20)로 보낸다. 이때, 신호처리부(20)에서는 입력되는 펄스신호를 조정하여 톤발생부(21)로 송출하면 톤발생부(21)에서는 음성급의 톤을 이/엠유니트와 정합할 수 있는 음성신호정합부(23)로 송출한다.The mother station matching device 9 and the home station matching device 16 will be described in more detail with reference to FIG. 3. In the mother station matching device 9, a pulse signal and a remote power supply input to the cable air pressure monitoring host device matching unit 18 will be described. The remote power supply control unit 19 blocks the remote power supply and sends only a pulse signal to the signal processing unit 20. At this time, the signal processing unit 20 adjusts the input pulse signal and sends it to the tone generating unit 21, the tone generating unit 21, the voice signal matching unit 23 that can match the tone of the voice level with the E / M unit 23 To be sent.

다른 구현 방법으로, 신호처리부(20)에 입력되는 펄스신호를 직접 이/엠유니트와 정합할 수 있는 이/엠신호정합부(24)로 송출한다.In another implementation, the pulse signal input to the signal processing unit 20 may be sent to the E / M signal matching unit 24 which may directly match with the E / M unit.

이의 역으로 음성신호정합부(23)로 입력되는 음성급의 톤은 톤검출부(22)에서 검출되어 신호처리부(20)에서 펄스신호로 변환된 후, 원격급전제어부(19)와 케이블공기압력감시주장치 정합부(18)를 거쳐서 케이블공기압력감시주장치(2)로 보내진다.On the contrary, the tone of the voice level input to the voice signal matching unit 23 is detected by the tone detector 22 and converted into a pulse signal by the signal processing unit 20, and then the remote power supply control unit 19 and the cable air pressure monitoring device. The cable is sent to the cable air pressure monitoring device 2 via the matching unit 18.

다른 구현 방법으로, 이/엠신호정합부(24)로 입력된 펄스신호를 직접 신호처리부(20)로 보내서 원격급전제어부(19)와 케이블공기압력감시주장치 정합부(18)를 거쳐서 케이블공기압력감시주장치(2)로 송출한다.In another embodiment, the cable air pressure monitoring via the remote power supply control unit 19 and the cable air pressure monitoring host matching unit 18 by sending the pulse signal input to the E / M signal matching unit 24 directly to the signal processing unit 20. It sends to the main apparatus (2).

자국정합장치(16)에서는 음성신호정합부(25)를 통해 입력되는 모국(1)의 음성급의 톤을 톤검출부(28)에서 검출하여 신호처리부(29)로 보낸다. 신호처리부(29)에서는 상기 모국(1)의 음성급의 톤을 펄스신호로 변환하여 원격급전제어부(30)와 감지기선로정합부(31)를 거쳐 외부로 송출한다.In the home station matching device 16, the tone detection unit 28 detects the tone of the voice level of the mother station 1 input through the voice signal matching unit 25 and sends it to the signal processing unit 29. The signal processing unit 29 converts the tone of the voice level of the mother station 1 into a pulse signal and transmits it to the outside via the remote power supply control unit 30 and the sensor line matching unit 31.

다른 구현 방법으로, 이/엠신호정합부(26)에 입력되는 펄스신호를 직접 신호처리부(29)로 보내서 원격급전제어부(30)와 감지기선로정합부(31)를 거쳐 외부로 송출한다.In another implementation method, the pulse signal input to the E / M signal matching unit 26 is directly sent to the signal processing unit 29 and transmitted to the outside via the remote power supply control unit 30 and the sensor line matching unit 31.

한편, 감지기선로정합부(31)로 입력되는 펄스신호의 케이블공기압력감시의 결과보고는 원격급전제어부(30)를 거쳐 신호처리부(29)에 입력되면 신호처리부(29)에서는 입력되는 펄스신호를 조정하여 톤발생부(27)로 송출하고, 톤발생부(27)에서는 톤신호로 변환하여 음성신호정합부(25)로 송출한다.On the other hand, when the result of the cable air pressure monitoring of the pulse signal input to the detector line matching unit 31 is input to the signal processing unit 29 via the remote power supply control unit 30, the signal processing unit 29 receives the input pulse signal The tone generator 27 converts the tone signal to the tone generator 27, and converts the tone signal into a tone signal to the voice signal matching unit 25.

다른 구현 방법으로, 신호처리부(29)로 입력된 펄스신호를 직접 이/엠신호정합부(26)로 송출하여 이/엠유니트와 정합한다.In another implementation, the pulse signal input to the signal processing unit 29 is directly sent to the E / M signal matching unit 26 to match with the E / M unit.

모국과 자국간의 실선 구간이 광선로로 대체되어도 저렴하게 구현되는 모국정합장치 및 자국정합장치를 부가 설치하면 광선로를 이용해서 정상적인 운용을 할 수 있기 때문에, 종래의 케이블공기압력감시주장치와 감지기를 새로이 개발하거나 교체하지 않고 종래의 시설을 활용할 수 있는 경제적인 효과가 있으며, 운용환경을지속적으로 활용하는 것이 가능하게 된다.If a mother line matching device and its own matching device are installed at low cost even if the solid line section between the mother country and the local station is replaced by the optical line, normal operation can be performed using the optical line. There is an economic effect that can utilize the existing facilities without replacement or replacement, it is possible to continue to use the operating environment.
