종래에 있어서의 레일의 온도검지의 요령은, 제4도에 표시한 바와 같이, 측정자가 레일설치장소에 온도센서를 가지고 나가서, 열차가 왕래하는 사이를 누비고 레일의 온도를 측정하고, 그 측정결과를 운전사령부등에 보고하고 있었다. 또, 보고를 받고 운전사령부는 보고된 온도데이터를 기초로 레일의 온도분포 및 변형을 추정하고, 경보를 발하도록 하고 있었다.In the conventional method of detecting the temperature of the rail, as shown in FIG. 4, the measurer takes the temperature sensor to the rail installation place, walks between trains, and measures the temperature of the rail. Was reported to the headquarters. In addition, based on the reported temperature data, the operation command estimated the temperature distribution and deformation of the rail and issued an alarm.
그러나, 상기한 바와 같은 종래의 레일온도검지를 행함에 있어서는, 대상으로 하는 노선전체선로에 걸쳐서 광범위하게 다수의 측정자를 배치하지 않으면 안되었다. 또한, 측정포인트의 간격을 충분히 미세하게해서 연속적인 레일온도분포를 검지할려고 하는 경우에는, 다수의 측정자와 다대한 시간을 필요로 하고 있었다.However, in performing the conventional rail temperature detection as described above, it is necessary to arrange a large number of measuring instruments over the entire route line as a target. In addition, when trying to detect the continuous rail temperature distribution by making the space | interval of a measurement point fine enough, it requires a lot of time with a large number of measuring machines.
또, 레일의 온도측정을 열차가 주행하는 사이에 측정자가 행하지 않으면 안되기 때문에, 위험을 수반하는 것이었다.In addition, since the measuring person had to perform the rail temperature measurement while the train was running, it was accompanied by a danger.
본 발명은 상기과제를 해결하기 위하여 이루어진 것으로서, 그 목적은, 측정자를 현지(레일 설치장소)에 파견하지 않고 레일의 온도측정이 가능한 장치를 제공하는데 있다.The present invention has been made to solve the above problems, and an object thereof is to provide an apparatus capable of measuring a temperature of a rail without dispatching a measurer to a site (rail installation site).

And a control console which outputs one position information together with the alarm information and transmits it wirelessly, and a control console which is installed in a train driving command unit and receives the output signal of the processor to display the temperature distribution of the rail in real time. .
본 발명에 있어서는, 열차주행중에 레일의 온도를 측정하기 위하여, 고속의 샘플링이 가능한 적외선화상온도센서와 화상처리를 행하는 처리기를 열차에 탑재하고, 이에 의해 레일온도를 일정한 간격에서 순시간에 측정한다. 또, 레일온도를 측정한 위치를 표정(標定)하기 위하여, 열차에 GPS수신기 및/또는 자율항법장치를 장비하고, 온도측정과 동기한 위치정보를 검출한다.In the present invention, in order to measure the temperature of the rail while the train is running, an infrared image temperature sensor capable of high-speed sampling and a processor for performing image processing are mounted on the train, whereby the rail temperature is measured at regular intervals at regular intervals. . In addition, in order to express the position at which the rail temperature is measured, the train is equipped with a GPS receiver and / or an autonomous navigation device, and the position information synchronized with the temperature measurement is detected.
상기에 의해 얻어진 레일온도, 온도측정위치, 온도에 관한 경보정보는, 열차로부터 운전사령부의 제어콘솔에 열차무선시스템을 이용해서 전송한다. 그를 위해, 전체선로의 온도분포를 제어콘솔에 의해 표시할 수 있어 레일온도의 모니터가 가능하게 된다.The alarm information relating to the rail temperature, the temperature measurement position, and the temperature obtained as described above is transmitted from the train to the control console of the driving command unit using the train radio system. For that purpose, the temperature distribution of the entire line can be displayed by the control console, so that the rail temperature can be monitored.
또한, 위치정보의 검출은, 경우에 따라서 단독으로 설치된 GPS수신기 또는 자율항법장치가 행하는 일도 있고, 양자를 함께 배설해서, 상호간에 보완시켜서 행하여도 된다.In addition, detection of positional information may be performed by the GPS receiver or autonomous navigation apparatus installed independently in some cases, and may mutually complement and complement each other.
이하, 본 발명의 일실시예에 관한 레일온도검지장치에 대해서, 제1도 내지 제3도에 의해 설명한다. 제1도에 표시한 본 실시예의 장치는, 레일(1)위를 주행하는 열차(10)에 각각 설치된 GPS안테나(3)을 가진 GPS수신기(8), 자율향법장치(9), 적외선화상온도센서(2), 처리기(4) 및 열차무전기(5)와, 운전사령부(11)등에 설치된 제어콘솔(6)과, 상공에 쏘아올린 GPS위성(7)에 의해 구성되고 있다.Hereinafter, a rail temperature detecting device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The apparatus of the present embodiment shown in FIG. 1 includes a GPS receiver 8, an autonomous navigation apparatus 9, and an infrared image temperature each having a GPS antenna 3 installed in a train 10 traveling on a rail 1, respectively. It consists of a sensor 2, a processor 4 and a train radio 5, a control console 6 provided in the driver command unit 11 and the like, and a GPS satellite 7 launched in the air.
상기에 있어서, 주행중의 열차(10)에 탑재된 적외선온도센서(2)는 레일(1)을 검지하고, 그 적외선화상을 형성하고, 그것을 적당한 샘플링간격으로 처리기(4)에 전송하고, 처리기(4)는 화상처리를 행하여, 레일(1)의 온도를 산출한다.In the above, the infrared temperature sensor 2 mounted on the traveling train 10 detects the rail 1, forms the infrared image, and transmits it to the processor 4 at an appropriate sampling interval. 4 performs image processing to calculate the temperature of the rail 1.
상기 처리기(4)에 입력되는 제2도에 표시한 적외선화상(12)는, 계조(gradation)가 참조온도(13)에 따르게하고, 참조온도(13)은 계조가 부여된 온도범위에서 온도분해능과 동일스텝으로 변화하고, 온도는, 계조의 함수로 되어 있다. 적외선화상(12)에 비쳐져 있는 레일(1a)는, 참조온도(13)에 따라 계조가 다르게 되어 있다.The infrared image 12 shown in FIG. 2 input to the processor 4 causes the gradation to conform to the reference temperature 13, and the reference temperature 13 has a temperature resolution in the temperature range to which the gradation is applied. The temperature changes as a function of gradation. The rail 1a reflected on the infrared image 12 has a different gradation depending on the reference temperature 13.
상기 처리기(4)는, 적외선화상(12)가 처리기(4)에 보내지는 샘플링간격내에 다음의 처리를 행한다. 레일(1a)를 포함하는 화상(pixel)을 판독해 넣고(공정 14참조), 각화소의 계조를 판정한다(공정 15참조). 레일(1a)를 비쳐내는 화소중에서부터 가장 고온을 표시한 계조의 화소를 선택하고, 선택된 화소의 계조와 참조온도 13의 계조를 비교해서 레일(1a)의 온도를 검출한다(공정 16참조). 상기의 처리는 적외선화상(12)가 처리기(14)로 보내질때마다 행하여진다.The processor 4 performs the following processing within the sampling interval at which the infrared image 12 is sent to the processor 4. An image containing the rail 1a is read out (see step 14), and the gradation of each pixel is determined (see step 15). From the pixels illuminating the rail 1a, a pixel of the highest gradation level is selected, and the temperature of the rail 1a is detected by comparing the gradation of the selected pixel with the gradation of the reference temperature 13 (see step 16). The above process is performed every time the infrared image 12 is sent to the processor 14.
또, 상기 처리기(4)는, GPS송신기(8), 자율항법장치(9)로부터 레일(1a)의 위치를 입력하고, 레일온도측정과 동기해서 표정한 위치를 레일(1a)의 온도와 함께 열차무전기(5)에 보내고, 동무전기(5)는 디지털·데이터전송에 의해 운전사령부등(11)의 제어콘솔(6)으로 보낸다.In addition, the processor 4 inputs the position of the rail 1a from the GPS transmitter 8 and the autonomous navigation device 9, and displays the position expressed in synchronization with the rail temperature measurement together with the temperature of the rail 1a. The radio is sent to the train radio 5, and the radio 5 is sent to the control console 6 of the driving command unit 11 by digital data transmission.
또한, 상기 처리기(4)는, GPS위성(7)로부터의 전파가 도달하는 곳에서는, GPS안테나(3)이 설치된 GPS수신기(8)로부터 위치정보를 입력하고, 고정밀도의 위치표정을 행하고, 전파가 도달하지 않는 터널내부등에서는, 자율항법장치(9)에 의해 위치표정을 행한다. 본 실시예는 위치정보로서, GPS수신기(8)과 자율항법장치(9)를 상호보완하는 관계에서 사용하고 있으나, 이에 한정되는 것이 아니라, 경우에 따라서는 GPS수신기(8) 및 자율항법장치(9)중의 어느쪽이든 한쪽만을 단독으로 사용해도 된다.Further, the processor 4 inputs position information from the GPS receiver 8 in which the GPS antenna 3 is installed, where radio waves from the GPS satellites 7 arrive, and performs high-precision positioning. In tunnels and the like where radio waves do not reach, positioning is performed by the autonomous navigation device 9. In the present embodiment, as the position information, the GPS receiver 8 and the autonomous navigation device 9 are used to complement each other. However, the present invention is not limited thereto. In some cases, the GPS receiver 8 and the autonomous navigation device ( Either one of 9) may be used alone.
상기 운전사령부(11)등에 설치된 제어콘솔(6)은, 열차(10)으로부터 보내지는 레일(1)의 온도정보, 위치정보 및 경보정보등에 의거해서 제3도에 표시한 바와 같은 화면을 형성하고, 리얼타임으로 레일(1)의 온도분포를 모니터한다.The control console 6 installed in the driving command unit 11 or the like forms a screen as shown in FIG. 3 based on temperature information, position information, alarm information, etc. of the rail 1 sent from the train 10, and the like. The temperature distribution of the rail 1 is monitored in real time.
