Abstract
Description
本発明は、鉄道車両及び保安装置に関し、特に鉄道車両の保安装置において、受電器の断線を検査する方法に関する。 The present invention relates to a railway vehicle and a safety device, and more particularly to a method for inspecting a disconnection of a power receiver in a railway vehicle security device.
鉄道車両の保安装置は、地上装置からの信号に従い列車の速度を制限する。自動列車制御装置(ATC装置)などは、地上装置から車上装置への信号の伝達にレールを使用しており、車上装置は受電器でレールからの信号を受信する。受電器が故障した場合には、車上装置は信号が受信できなくなり、信号にあわせた列車速度の制限が不可能となる。したがって、保安装置の検査では受電器に断線がないことを確認し、信号が受信できることを確認しなければならない。 The railroad vehicle security device limits the speed of the train according to a signal from the ground device. An automatic train control device (ATC device) or the like uses a rail to transmit a signal from a ground device to an on-vehicle device, and the on-vehicle device receives a signal from the rail with a power receiver. When the power receiver breaks down, the on-board device cannot receive a signal, and it is impossible to limit the train speed according to the signal. Therefore, in the inspection of the security device, it is necessary to confirm that the power receiver is not disconnected and to confirm that the signal can be received.
従来の受電器の断線の確認方法としては、以下の2つの方法が挙げられる。
(1)試験器を使用してレールもしくはループコイルに模擬信号を送信し、この信号を受電器が受信することで確認する方法。
(2)受電器内に受信コイルと試験コイルの2つのコイルがある受電器を使用し、車上保安装置内で生成した模擬信号を受電器内の試験コイルに送信し、この信号を受信コイルが受信することで確認する方法。
どちらの方法も、受信コイルで受信した模擬信号を保安装置内の受信部が検知し、模擬信号を検知できない場合に断線検知と判断している。
(1) A method in which a simulated signal is transmitted to a rail or loop coil using a tester, and this signal is received by a power receiver and confirmed.
(2) Using a power receiver that has two coils, a receiving coil and a test coil, in the power receiver, a simulated signal generated in the vehicle safety device is transmitted to the test coil in the power receiver, and this signal is received by the receiving coil. To confirm by receiving.
In both methods, when the simulated signal received by the receiving coil is detected by the receiving unit in the security device and the simulated signal cannot be detected, it is determined that the disconnection is detected.
前記(2)の試験方法を実施するためには、試験コイルをもつ受電器が必要である。しかしながら、既存の車両の保安装置を更新した場合など既存の受電器を使用する場合には、受電器に試験コイルがないものも存在する。この場合には、受電器も更新して車両の艤装改造しなければ車上保安装置で車上試験を行う前記(2)の方法では試験が出来ず、試験器や地上設備が必要となる前記(1)の方法でしか試験が出来なかった。 In order to implement the test method (2), a power receiver having a test coil is required. However, when an existing power receiver is used, such as when an existing vehicle security device is updated, some power receivers do not have a test coil. In this case, if the power receiver is also renewed and the vehicle is not remodeled, the test on the vehicle with the on-board safety device cannot be tested by the method (2), and a tester and ground equipment are required. The test was possible only by the method (1).
そこで、本発明では受電器内に試験コイルがない場合にも、試験器や地上設備が必要とせずに、車上検査で受電器の断線検知を可能とする鉄道車両及び保安装置を提供することを目的とする。 Therefore, the present invention provides a railway vehicle and a safety device that can detect a disconnection of a power receiver in an on-vehicle inspection without requiring a tester or ground equipment even when there is no test coil in the power receiver. With the goal.
本発明では、車上保安装置内で生成した模擬信号を受電器の受信コイルに直接送信する。模擬信号の入力端より保安装置の受信部側で断線が発生した場合には、従来同様模擬信号が受信できなくなる。しかし、模擬信号の入力端よりも受信器側で断線が発生した場合には、受電器のコイル抵抗分の負荷がなくなることから、保安装置の受信部で受信する信号レベルは上昇する。この変化を検知することで、受電器側での断線も検知が可能となる。 In the present invention, the simulation signal generated in the onboard safety device is directly transmitted to the receiving coil of the power receiver. When a disconnection occurs on the receiving unit side of the security device from the input end of the simulated signal, the simulated signal cannot be received as in the prior art. However, when a disconnection occurs on the receiver side with respect to the input end of the simulation signal, the load corresponding to the coil resistance of the power receiver is lost, and the signal level received by the receiving unit of the security device increases. By detecting this change, disconnection on the power receiver side can also be detected.
すなわち、本発明は、地上装置からの信号を受信する受信コイルを有する受電器と、該受電器から、信号線を介して受信信号を受け取り、列車の速度を制限する信号を出力する保安装置とを搭載する鉄道車両において、前記保安装置は、生成した車上検査の模擬信号を、前記信号線を介して前記受電器の受信コイルに送信し、前記模擬信号に対する前記受電器の応答の有無及び正常状態からの受信レベルの変化を検知する鉄道車両である。 That is, the present invention provides a power receiver having a receiving coil that receives a signal from a ground device, and a security device that receives a received signal from the power receiver via a signal line and outputs a signal that limits the speed of a train; In the railway vehicle, the safety device transmits the generated on-vehicle simulation signal to the receiving coil of the power receiver via the signal line, and whether or not the power receiver responds to the simulated signal and This is a railway vehicle that detects a change in reception level from a normal state.
また、本発明は、鉄道車両に搭載され、地上装置からの信号を受信する受信コイルを有する受電器から、信号線を介して受信信号を受け取り、列車の速度を制限する信号を出力する保安装置において、生成した車上検査の模擬信号を、前記信号線を介して前記受電器の受信コイルに送信し、前記模擬信号に対する前記受電器の応答の有無及び正常状態からの受信レベルの変化を検知する保安装置である。 Further, the present invention is a security device that is mounted on a railway vehicle and receives a received signal via a signal line from a power receiver having a receiving coil that receives a signal from a ground device, and outputs a signal that limits the speed of the train. , The generated simulation signal for on-vehicle inspection is transmitted to the receiving coil of the power receiver via the signal line, and the presence or absence of the response of the power receiver to the simulated signal and the change in the reception level from the normal state are detected. It is a security device.
本発明によれば、試験コイルを持たない受電器においても車上保安装置による車上検査で断線の検知が可能となる。これにより、既存車両の艤装改造が不要となり、車上検査時にループコイルや試験器が不要となる。 According to the present invention, even in a power receiver that does not have a test coil, disconnection can be detected by on-vehicle inspection by the on-vehicle security device. This eliminates the need for retrofitting existing vehicles and eliminates the need for loop coils and testers during on-board inspection.
本発明を実施するための最良の形態を説明する。
以下、本発明の鉄道車両及び保安装置の実施例について、図面を用いて説明する。
The best mode for carrying out the present invention will be described.
Hereinafter, embodiments of a railway vehicle and a security device of the present invention will be described with reference to the drawings.
実施例を説明する。図1は本実施例の車上保安装置の構成図、図2は本実施例において受電器を検査するための構成図である。図3は本実施例における車上保安装置の受信部における受電器断線を検知する手順のフローチャートを示した図である。 Examples will be described. FIG. 1 is a configuration diagram of a vehicle safety device according to the present embodiment, and FIG. 2 is a configuration diagram for inspecting a power receiver in the present embodiment. FIG. 3 is a flowchart illustrating a procedure for detecting a disconnection of the power receiver in the receiving unit of the on-vehicle security device according to the present embodiment.
図1において、車上保安装置4は、鉄道車両1に搭載され、地上装置からの信号を、レール2及び受電器3を介して受信する。この受信した信号を運転台の表示部5に表示して運転士に制限速度を知らせると同時に、列車速度が制限速度を上回った場合にはブレーキ指令によりブレーキを動作させて列車速度を制限する。
In FIG. 1, an on-vehicle security device 4 is mounted on a
図2は、信号を受信する受電器3を検査するための構成図である。車上保安装置4の検査部42を、受電器3と車上保安装置4の受信部41とを結ぶ信号線6に接続し、検索部42で発生させた模擬信号を送信する。試験コイルを持たない受電器3の場合、車上保安装置4内の検査部42からの模擬信号を、受電器3の受信コイルに対し、信号線5を介して送信し、受電器3の応答の有無及び正常状態からの受信レベルを受信部41で検知する。例えば、図2のA部(模擬信号入力端より受信部41側)で断線が発生した場合には、受信部41では模擬信号が受信できなくなり、断線と判断することが可能である。図2のB部(模擬信号入力端より受電器3側)で断線が発生した場合には、受電器3のコイル抵抗分の負荷がなくなることから、受信部41での模擬信号の受信レベルが上昇するので、断線と判断することが可能である。
FIG. 2 is a configuration diagram for inspecting the power receiver 3 that receives a signal. The
図3は実施例における受電器の断線を検知する手順のフローチャートを示した図である。まず、車上検査にて受電器3の試験を実施する(S101)。つぎに、車上保安装置4から模擬信号を送信する(S102)。受信部41が模擬信号を受信するか判断する(S103)。ステップS103で受信できなければ、受電器3の断線が図2のA部で発生と判断できる。ステップS103で受信できると、通常よりも受信レベルが高いか判断する(S104)。ステップS104で通常よりも高いとき、受電器3の断線が図2のB部で発生と判断できる。ステップS104で通常よりも高くないとき、受電器3の断線なしと判断できる。このようにして、受電器3の断線の発生の有無及び発生個所を判断することができる。
FIG. 3 is a diagram illustrating a flowchart of a procedure for detecting disconnection of the power receiver in the embodiment. First, a test of the power receiver 3 is performed by an on-vehicle inspection (S101). Next, a simulation signal is transmitted from the onboard security device 4 (S102). It is determined whether the
