전동차의 무선시스템시험장치Wireless system test apparatus of electric vehicle

본 고안은 전동차와 지상 중앙제어실 사이에 통신을 교환하기 위한 열차무선시스템의 시험장치에 관한 것으로서, 보다 상세하게는 통신을 위한 시스템의 무선 송·수신상태와 안테나의 절환상태, 근거리통신망의 구동장치와 단자대로서 상기 무선통신시스템을 시험 점검하고, 무선시스템의 기록과 이력 등을 관리할 수 있도록 하는 전동차의 무선시스템 시험장치에 관한 것이다.The present invention relates to a test apparatus for a train radio system for exchanging communication between an electric vehicle and a ground central control room, and more particularly, a wireless transmission / reception state of a system for communication, a switching state of an antenna, a driving device of a local area network. And a terminal block for testing and checking the wireless communication system and managing a record and history of the wireless system.

일반적으로 전동차의 무선시스템은 지상 중앙제어실에서 총괄 관리하도록 되어 있고, 지상 중앙제어실과 전동차간의 긴밀한 통신에 따라 선행열차의 개통관계, 전동차의 이상유무 상태 등을 종합 관리하도록 되어 있으며, 상기 전동차가 이동물체이므로 이동하는 전동차와의 교신은 무선시스템에 의해 이루어지고 있으며, 상기 무선시스템에 의한 통신망 구축은 전동차의 운영에 매우 중요한 시스템이다.In general, the wireless system of the electric vehicle is to be managed in the ground central control room as a whole, and the overall control of the opening relations of the preceding trains and the abnormal state of the electric car according to the intimate communication between the ground central control room and the electric vehicle is performed. Communication with a moving electric vehicle is made by a wireless system because it is an object, and communication network construction by the wireless system is a very important system for operating an electric vehicle.

따라서, 상기 무선시스템에 이상이 발생하거나 송·수신의 절환이 원활하게 이루어지지 않을 경우에는 전동차의 운행을 중지할 수밖에 없으며, 상기 무선시스템의 두절시 임의로 운행하는 것은 매우 위험한 일이다. 이에 따라 상기 무선시스템의 시험 및 검사는 수시로 해야하고, 또 정확하게 이루어져야 하는바, 종래에는 상기 무선시스템을 종합적으로 시험 검사할 수 있는 장치가 없었기 때문에 점검부위를 일일이 검사자가 확인하면서 시험 검사를 해야 했으며, 일괄적인 시험 검사가 이루어지지 않아 검사시간이 많이 걸리게 되었다.Therefore, when an abnormality occurs in the wireless system or when switching between transmission and reception is not performed smoothly, the operation of the electric vehicle cannot be stopped, and it is very dangerous to operate arbitrarily when the wireless system is broken. Accordingly, the test and inspection of the wireless system should be frequently and accurately performed. In the past, since there was no device for comprehensively testing the wireless system, the inspection site had to be checked and inspected by the inspector. As a result, the test was not carried out in a batch and the inspection time was long.

또한, 무선시스템을 정확한 진단할 수 없이 상기 통신망의 운영중 종종 이상이 발생되어 전동차의 운행지연이 발생되는 등의 문제점이 있었다.In addition, there is a problem such that the operation of the communication network is often caused by abnormal occurrence during operation of the communication network without accurately diagnosing the wireless system.

이에 본 고안은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 주제어반에서 시험반을 제어하도록 하고, 시험반에서는 무선시스템을 시험 검사하도록 하며, 시험 검사된 데이터를 상기 주제어반에서 입력 관리하면서 무선시스템의 고장을 진단하고, 이와 더불어 무선시스템의 각 부품에 대한 수명상태 등의 이력을 체크하여 예상수명을 검진하도록 하므로써, 무선시스템의 원활한 운영과 예방정비를 도모할 수 있도록 하는 전동차의 무선시스템시험장치를 제공함에 있다.The present invention is conceived in view of the above problems, the purpose is to control the test panel in the main control panel, the test panel to test the wireless system, and to manage the test-tested data in the main panel The wireless system test of the electric vehicle which can diagnose the failure of the system and check the life expectancy by checking the history of the life state of each part of the wireless system, so that the smooth operation and preventive maintenance of the wireless system can be achieved.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 구체적으로 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 전동차의 무선시스템시험장치의 구성을 나타내는 구성도이다. 도 1에 도시된 바와 같이, 전동차와 지상 중앙제어실간을 연결하게 되는 안테나(12)를 무선시스템시험반(B)에 연결시키고, 상기 무선시스템에서 요구되는 시험항목과 조건 및 기술제원 등에 대한 데이터를 입력시켜 상기 장치의 시험 및 측정결과를 비교분석하여 장치의 이력을 중앙처리장치(CPU)에서 기억관리하며, 상기 중앙처리장치(CPU)의 입출력을 디스플레이하는 모니터(2)를 구비한 시험진행반(1)에서 상기 무선시스템의 시험항목과 조건 및 기술제원 등을 검사하기 위한 제어테이터를 무선시스템시험반(B)의 컨트롤러에 입력하고, 컨트롤러에서는 상기 제어데이터에 의해 무선시스템의 작동상태를 검사한다.1 is a block diagram showing the configuration of a radio system test apparatus for an electric vehicle according to the present invention. As shown in FIG. 1, an antenna 12 connecting the electric vehicle and the ground central control room is connected to the wireless system test panel B, and data about test items, conditions, technical specifications, and the like required for the wireless system are connected. A test progress panel having a monitor (2) which inputs and compares and analyzes the test and measurement results of the device, and stores the history of the device in the central processing unit (CPU), and displays the input and output of the central processing unit (CPU). In (1), control data for checking test items, conditions, technical specifications, and the like of the wireless system are input to the controller of the wireless system test panel (B), and the controller checks the operation state of the wireless system by the control data. .

즉, 무선시스템시험반(B)의 송·수신테스트시스템(8)과 송·수신릴레이(9)를 통해 전동차와 중앙제어실간의 무선시스템을 연결하는 안테나(12)를 통해 폐회로를 형성하고, 상기 무선시스템의 작동전원은 전원부(C)의 트랜스(5)와 UPS(6) 및 전원분배기(7)를 통해 전원반(10)으로 전원을 공급하여 무선시스템시험반(B)으로 전원을 공급하게 된다.That is, a closed circuit is formed through an antenna 12 connecting the wireless system between the electric vehicle and the central control room through the transmission / reception test system 8 and the transmission / reception relay 9 of the wireless system test panel B. The operating power of the system is supplied to the wireless system test panel (B) by supplying power to the power panel (10) through the transformer (5) of the power supply (C), the UPS (6) and the power distributor (7).

따라서, 무선시스템시험반(B)에서는 시험진행반(1)에서 송출된 제어데이터에 의해 전동차의 무선시스템에서 요구되는 송·수신장치의 절환상태와 송·수신 감도를 측정검사하게 되고, 전동차와 지상 중앙제어실간의 무선시스템의 작동유무와 송수신감도를 검사하게 되는 것이다.Therefore, the wireless system test panel B measures and checks the switching state and transmission / reception sensitivity of the transmission / reception apparatus required by the radio system of the electric vehicle by the control data transmitted from the test progress panel 1, and the electric vehicle and the ground. The wireless system between the central control room is checked and the transmission and reception sensitivity is checked.

상기 과정에서 검사된 데이터는 중앙처리장치(CPU)에서 컨트롤하면서 모니터(2)의 화면에 무선시스템에 해당되는 전기배선도와 송수신감도를 표시하는 동시에 자료처리반(4)의 데이터베이스에 입력시켜 저장하게 되며, 프린터(3) 등과 같은 출력장치를 통해 저장된 데이터를 출력시키게 된다.The data examined in the above process is controlled by the central processing unit (CPU) and displays the electrical wiring diagram and the transmission / reception sensitivity corresponding to the wireless system on the screen of the monitor (2), and is stored in the database of the data processing unit (4). The stored data is output through an output device such as a printer 3 or the like.

따라서, 무선시스템시험반(B)은 시험진행반(1)의 중앙처리장치(CPU)에서 송출된 데이터에 따라 전동차와 중앙제어실간의 무선시스템의 송·수신 절환상태 및 통신상태에 따른 장치의 이상유무 및 이력 등을 판단하게 되고, 판단된 데이터로 무선시스템의 고장여부를 사전진단하여 예방정비를 행하게 되므로 전동차의 무선시스템의 고정을 미연에 방지하게 되는 것이다.Therefore, the wireless system test panel B is in accordance with the data sent from the central processing unit (CPU) of the test progress panel (1) according to the transmission and reception of the wireless system between the train and the central control room and the abnormality of the device according to the communication status And history, and the like, and preventive maintenance is performed by pre-diagnosing whether the wireless system is broken with the determined data, thereby preventing the fixing of the wireless system of the electric vehicle.

이상에서 살펴본 바와 같이, 본 고안은 전동차의 운행 전후에 전동차와 지상 중앙제어실간의 무선통신시스템을 미리 정해진 데이터에 따라 시험 및 검사를 하며, 시험된 데이터에 따라 무선시스템의 이상유무와 각 부품의 수명상태 등의 이력을 수집 관리하므로서 보다 정확한 검사를 할 수 있고, 또 전동차 운행중 무선시스템의 고장발생을 미연에 방지하므로 전동차의 원활한 운행과 더불어 통신망의 원활한 운영을 도모할 수 있게 되는 장점을 갖는 매우 유용한 고안인 것이다.As described above, the present invention tests and inspects the wireless communication system between the electric vehicle and the ground central control room according to predetermined data before and after the operation of the electric vehicle, and according to the tested data, there is an abnormality of the wireless system and the life of each component. By collecting and managing the history, etc., it is possible to conduct more accurate inspections and to prevent the occurrence of the failure of the wireless system while the train is in operation. Therefore, it is very useful to have the smooth operation of the train and the smooth operation of the communication network. It is an idea.
