Abstract

<P>PROBLEM TO BE SOLVED: To provide a vehicle type distinction method improving safety by performing a check while requiring no equipment on the outside of a vehicle. <P>SOLUTION: Vehicle recognition signals 21, 22 are input into an ATC device from the vehicle side, and setting values (910, 1,026) of a wheel diameter are set by using a wheel diameter setting switch 23 in the ATC device. The vehicle recognition signals 21, 22 are signals displayed by code in such a way that if an input pin has a signal of an A vehicle, the code is "1", and if no signals, the code is "0". The setting values of the wheel diameter become signals coded according to the setting values. These coded signals are processed by a logic circuit, and the vehicle type is distinguished. Since the vehicle type is distinguished by using the vehicle recognition signal of the vehicle interior and the wheel diameter setting switch, the vehicle distinction is doubly checked based on the information of the vehicle interior, and can surely be performed. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、電車、モノレール、新交通等のような軌条を走行する軌条車両の車種判別方法に関する。   The present invention relates to a method for discriminating a vehicle type of a rail vehicle that travels on a rail such as a train, a monorail, and a new traffic.

軌条車両の車輪に関して、その車輪径の測定が求められるような場合として、振り子式鉄道車両における車輪径の補正（例えば、特許文献１参照）が挙げられる。振り子制御式鉄道車両の車輪径自動補正方法では、ある基準地上子間毎の走行パルス数と距離データから車輪径を演算することが行われている。   As a case where the wheel diameter of a rail vehicle wheel is required to be measured, correction of the wheel diameter in a pendulum type railway vehicle (for example, see Patent Document 1) can be given. In the automatic wheel diameter correction method for a pendulum control type railway vehicle, the wheel diameter is calculated from the number of travel pulses and distance data for each reference ground element.

また、走行路に複数のセンサを設置し、走行中における車両の車輪の大きさを検出し、車輪の大きさから車両の種類を判別する車種別方法が提案されている（特許文献２）。この方法は道路上を走行する車両（自動車）に限らず、軌道上を走行する鉄道車両等の車種判別にも適用可能である。   In addition, a vehicle type method has been proposed in which a plurality of sensors are installed on a travel path, the size of a vehicle wheel during travel is detected, and the type of vehicle is determined from the size of the wheel (Patent Document 2). This method is applicable not only to vehicles (automobiles) that travel on the road but also to vehicle type discrimination such as railway vehicles that travel on the track.

上記のような従来技術による判別方法は、車両外部から得た情報に基づいて車種を判別する方法であり、これを実施するには、地上子・センサなどの地上側設備の設置が必要となる問題があり、コストがかかるものとなっている。
特開２００１−１０６０７０号公報 特開昭５９−４３５００号公報 The conventional discrimination method as described above is a method of discriminating a vehicle type based on information obtained from the outside of the vehicle, and in order to implement this, it is necessary to install ground side equipment such as a ground unit and a sensor. There are problems and costs.
JP 2001-106070 A JP 59-43500 A

そこで、車両外部から得た情報に基づくのではなく、車両内部の情報に基づいて、安価に軌条車両の車種を判別可能にする点で解決すべき課題がある。   Thus, there is a problem to be solved in that the type of rail vehicle can be discriminated at low cost based on information inside the vehicle, not based on information obtained from the outside of the vehicle.

本発明の目的は、車両外部の設備を不要としつつ、且つチェックを行って安全性を向上させた車種判別方法を提供することである。   SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle type discrimination method that eliminates the need for equipment outside the vehicle and improves safety by performing checks.

上記目的を達成するために、この発明による軌条車両の車種判別方法は、列車の速度が制限速度を超過したときに、ブレーキを出力して制限速度以下又は停止させるＡＴＣ装置による自動列車制御において、前記車両からの車両認識信号と前記ＡＴＣ装置内で設定される車輪径設定スイッチによる設定値とに基づいて車種判別することを特徴とする。   In order to achieve the above-mentioned object, the vehicle type discriminating method of the rail vehicle according to the present invention is an automatic train control by an ATC device that outputs a brake and stops or stops or stops when the train speed exceeds the limit speed. The vehicle type is discriminated based on a vehicle recognition signal from the vehicle and a set value by a wheel diameter setting switch set in the ATC device.

この軌条車両の車種判別方法によれば、車両側からＡＴＣ装置内に車両認識信号が入力され、また、ＡＴＣ装置内の車輪径設定スイッチを用いて車輪径の設定値が設定される。車両内部の車両認識信号と車輪径設定スイッチを用いて車種判別するので、車両の内部の情報に基づいて二重にチェックが働き、車種判別を確実に行うことができる。   According to the vehicle type discriminating method of the rail vehicle, a vehicle recognition signal is input into the ATC device from the vehicle side, and the wheel diameter setting value is set using the wheel diameter setting switch in the ATC device. Since the vehicle type is discriminated using the vehicle recognition signal inside the vehicle and the wheel diameter setting switch, a double check is performed based on the information inside the vehicle, and the vehicle type can be discriminated reliably.

この軌条車両の車種判別方法において、前記車両認識信号は実際の車種に応じてそれぞれ有無を出力するコード表示された信号値であり、それぞれの前記信号値と、前記車輪径設定スイッチによる前記設定値からコード変換された車輪径コードとを論理比較し、その論理比較結果に基づいて車種判別を行うことができる。   In this rail vehicle type discriminating method, the vehicle recognition signal is a code-displayed signal value for outputting presence / absence according to the actual vehicle type, and the signal value and the set value by the wheel diameter setting switch. Can be logically compared with the wheel diameter code that has been converted from the code, and the vehicle type can be determined based on the logical comparison result.

また、この軌条車両の車種判別方法において、前記論理比較は、前記車両認識信号の実際の車種に応じた前記有無を表す前記信号値と前記車輪径コードとが整合・非整合することに応じてそれぞれ０又は１を出力し、更に当該出力同士の論理和によって、その出力が０であるときに前記車種に応じた前記信号値を正常と判定することができる。
車両認識信号の一方の車種に応じた信号値及び車輪径コードが整合していれば０を出力し、整合していなければ１を出力する論理比較を行う。車両認識信号の他方の車種に応じた信号値においても同様の論理比較を行う。これらの論理比較結果について更に論理和を取ることにより、いずれの出力も０のときのみ当該論理和の出力が０となり、このとき車種に応じた信号値を正常と判定し車種判別を行うことができる。その他の場合には出力が１となり、このとき車種に応じた信号値を異常と判定する。 Further, in the vehicle type identification method of the rail vehicle, the logical comparison is performed according to whether the signal value indicating the presence / absence according to the actual vehicle type of the vehicle recognition signal and the wheel diameter code match or do not match. When the output is 0, the signal value corresponding to the vehicle type can be determined to be normal by outputting 0 or 1 respectively.
If the signal value corresponding to one vehicle type of the vehicle recognition signal and the wheel diameter code match, 0 is output, and if not, 1 is output. The same logical comparison is performed on the signal value corresponding to the other vehicle type of the vehicle recognition signal. By further taking a logical sum of these logical comparison results, the output of the logical sum becomes 0 only when both outputs are 0. At this time, the signal value corresponding to the vehicle type is determined to be normal and the vehicle type is determined. it can. In other cases, the output is 1, and at this time, the signal value corresponding to the vehicle type is determined to be abnormal.

更に、この軌条車両の車種判別方法において、前記コード変換に合わせて、前記車輪径設定スイッチによる前記設定値に基づいて正常と車輪径範囲外との正常異常検知コードを出力し、前記論理和の出力と前記正常異常検知コードとの更なる論理和に基づいて、車両認識異常の判定が行うことができる。   Further, in the vehicle type discriminating method of the rail vehicle, in accordance with the code conversion, a normal / abnormality detection code between normal and out of the wheel diameter range is output based on the set value by the wheel diameter setting switch, and the logical sum of Based on the further logical sum of the output and the normal / abnormality detection code, the vehicle recognition abnormality can be determined.

この発明によれば、車種の判定のために、車両外部の設備が不要となり、また判定を行う処理についても、車両認識信号と車輪径コードとに基づいて二重にチェックを行って安全性を向上させた車種判別方法及び装置を提供することができる。   According to the present invention, equipment outside the vehicle is not required for the determination of the vehicle type, and the process of performing the determination is also performed by performing a double check on the basis of the vehicle recognition signal and the wheel diameter code. An improved vehicle type identification method and apparatus can be provided.

以下、添付図面を参照して、この発明による車種判別方法の実施形態を説明する。図１は本発明である車種判別装置の一実施例を示すブロック図である。   Embodiments of a vehicle type identification method according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram showing an embodiment of a vehicle type discriminating apparatus according to the present invention.

図１に示すように、車両制御装置１１は、制御部１系１３、制御部２系１４、及びこれら２つの制御系の論理をとる共通部１７を統合した制御部１２と、車両側へ信号を伝える継電器部１８とを備えている。制御部１系１３と制御部２系１４とで２重系の制御部が構成されている。   As shown in FIG. 1, the vehicle control device 11 includes a control unit 12 that integrates a control unit 1 system 13, a control unit 2 system 14, and a common unit 17 that takes the logic of these two control systems, and a signal to the vehicle side. And a relay unit 18 for transmitting the information. The control unit 1 system 13 and the control unit 2 system 14 constitute a double control unit.

車両制御装置１１においては、車輪の回転に応じて発せられるパルス信号としての走行速度２４と、ＡＴＣ信号としての制限速度２５とが、制御基板１６，１６に入力される。制御基板１６，１６は、走行速度２４が制限速度２５を超過したと判定すると、ブレーキＯＮ指令の制御信号を出力し、列車を制限速度以下に減速又は停止させる。   In the vehicle control device 11, a traveling speed 24 as a pulse signal generated according to the rotation of the wheel and a speed limit 25 as an ATC signal are input to the control boards 16 and 16. When the control boards 16 and 16 determine that the traveling speed 24 exceeds the speed limit 25, the control boards 16 and 16 output a brake ON command control signal to decelerate or stop the train below the speed limit.

車輪径が異なるＡ車両とＢ車両との車種判別を行うため、Ａ車両の車両認識信号２１が装置の入力ピン（例えばピン番３）から入力され、Ｂ車両では装置の別の入力ピン（例えばピン番４）から車両認識信号２２が入力される。車両認識信号２１及び２２は、制御部１系１３及び制御部２系１４においてそれぞれ入出力基板１５，１５に入力され、入出力基板１５，１５を通して制御基板１６，１６へ車両認識信号（ＳＨ１，ＳＨ２）として転送され、後述する車種判別の処理が行われる。車両認識信号（ＳＨ１，ＳＨ２）は、それぞれの入力信号の有無に基づく信号であり、Ａ車両の有りのとき「１」、無しのとき「０」の値である。例えば、Ａ車両を選択してその信号が入力ピンに入力されるとき、車両認識信号２１は「１」である。このとき、通常は、Ｂ車両の信号が入力ピンに入力されることはなく、車両認識信号２２は「０」である。   In order to discriminate between the A vehicle and the B vehicle having different wheel diameters, the vehicle recognition signal 21 of the A vehicle is input from an input pin (for example, pin number 3) of the device. A vehicle recognition signal 22 is input from the pin number 4). The vehicle recognition signals 21 and 22 are input to the input / output boards 15 and 15 in the control unit 1 system 13 and the control unit 2 system 14, respectively, and are transmitted to the control boards 16 and 16 through the input / output boards 15 and 15. SH2) and the vehicle type discrimination process described later is performed. The vehicle recognition signals (SH1, SH2) are signals based on the presence / absence of each input signal, and have a value of “1” when the vehicle A is present and “0” when it is absent. For example, when the vehicle A is selected and the signal is input to the input pin, the vehicle recognition signal 21 is “1”. At this time, normally, the signal of the B vehicle is not input to the input pin, and the vehicle recognition signal 22 is “0”.

車両制御装置１１には、制御部１系１３及び制御部２系１４において、それぞれ車輪径を設定するスイッチ２３，２３が設けられている。スイッチ２３，２３では、Ａ車種（＝９１０）とＢ車種（＝０２６）に応じた値を設定する。ここで、「９１０」は車輪径９１０ｍｍを表し、「０２６」は車輪径１０２６ｍｍを表している。   The vehicle control device 11 is provided with switches 23 and 23 for setting wheel diameters in the control unit 1 system 13 and the control unit 2 system 14, respectively. In the switches 23 and 23, values corresponding to the A vehicle type (= 910) and the B vehicle type (= 026) are set. Here, “910” represents a wheel diameter of 910 mm, and “026” represents a wheel diameter of 1026 mm.

図２は、車種判別を実現する論理構成である。   FIG. 2 shows a logical configuration for realizing vehicle type discrimination.

スイッチ２３，２３で設定された車輪径設定値は、変換器３１で車輪径コード３７にコード変換される。即ち、設定値「９１０」は「０」に変換され、設定値「１０２６」は「１」に変換される。また、変換器３１は、コード変換と同時に、スイッチ２３での設定値が「９１０」，「１０２６」である場合には正常であることを示す「０」を出力し、「９１０」，「１０２６」以外である場合には車輪径範囲外３８として範囲外であることを示す「１」を出力する異常検知機能を備えている。   The wheel diameter set value set by the switches 23 and 23 is converted into a wheel diameter code 37 by the converter 31. That is, the set value “910” is converted to “0”, and the set value “1026” is converted to “1”. At the same time as the code conversion, the converter 31 outputs “0” indicating normality when the set values in the switch 23 are “910” and “1026”, and “910” and “1026”. If it is other than “”, an abnormality detection function for outputting “1” indicating that the wheel diameter is out of the range 38 is provided.

車種判別を正常と認識する論理構成は、Ａ車両で入力される車両認識信号２１と車輪径コード３７とが回路３２で比較され、車両認識信号２１が入力ありで且つ車輪径コード３７が「０」のとき、出力は正常（＝０）となる。
このとき、Ｂ車両で入力される車両認識信号２２と車輪径コード３７とは回路（ＸＯＲ回路）３３で比較され、車両認識信号２２が入力なし（即ち、車両認識信号２１が入力ありであるので、車両認識信号２２の方は入力なしが正常であるはず）で車輪径コード３７が「０」のとき、出力は正常（＝０）となる。 In the logical configuration for recognizing the vehicle type discrimination as normal, the vehicle recognition signal 21 input to the A vehicle and the wheel diameter code 37 are compared by the circuit 32, the vehicle recognition signal 21 is input, and the wheel diameter code 37 is “0”. ", The output is normal (= 0).
At this time, the vehicle recognition signal 22 and the wheel diameter code 37 input in the B vehicle are compared by a circuit (XOR circuit) 33, and the vehicle recognition signal 22 is not input (that is, the vehicle recognition signal 21 is input). When the vehicle recognition signal 22 should be normal without input) and the wheel diameter code 37 is “0”, the output is normal (= 0).

上記の論理構成は、車両認識信号２１が入力なしで車両認識信号２２が入力ありの場合も、車輪径コード３７が「１」となる外は同様であり、出力は正常（＝０）である。
即ち、Ｂ車両で入力される車両認識信号２２と車輪径コード３７とは回路３３で比較され、車両認識信号２２が入力ありで車輪径コード３７が「１」のとき、出力は正常（＝０）となる。
このとき、Ａ車両で入力される車両認識信号２１と車輪径コード３７とは回路３２で比較され、車両認識信号２１が入力なしで車輪径コード３７が「１」のとき、出力は正常（＝０）となる。 The logical configuration described above is the same except that the vehicle recognition signal 21 is not input and the vehicle recognition signal 22 is input, except that the wheel diameter code 37 is “1”, and the output is normal (= 0). .
That is, the vehicle recognition signal 22 and the wheel diameter code 37 input in the B vehicle are compared by the circuit 33. When the vehicle recognition signal 22 is input and the wheel diameter code 37 is “1”, the output is normal (= 0). )
At this time, the vehicle recognition signal 21 and the wheel diameter code 37 input in the A vehicle are compared by the circuit 32, and when the vehicle recognition signal 21 is not input and the wheel diameter code 37 is “1”, the output is normal (= 0).

回路（ＯＲ回路）３４では回路３２及び回路３３で得られた結果を突合せ、どちらの論理も正常なとき、つまり上記２つの例（回路３２の出力が「０」で、回路３３の出力も「０」の場合のみ）であるとき、出力は正常（＝０）となる。その他の場合では、出力は故障（＝１）となる。   In the circuit (OR circuit) 34, the results obtained in the circuit 32 and the circuit 33 are matched, and when both logics are normal, that is, in the above two examples (the output of the circuit 32 is “0” and the output of the circuit 33 is “ If only “0”, the output is normal (= 0). In other cases, the output is faulty (= 1).

異常検知機能の出力が車輪径範囲外３８（＝１）であるときは、回路３４における結果に関わらず車種を認識することができないため、回路（ＯＲ回路）３５で突合せ、車両認識異常３６（＝１）の出力を行う。車両認識異常３６（＝０）は正常である。   When the output of the abnormality detection function is out of the wheel diameter range 38 (= 1), the vehicle type cannot be recognized regardless of the result in the circuit 34, so the circuit (OR circuit) 35 makes a match and the vehicle recognition abnormality 36 ( = 1) is output. The vehicle recognition abnormality 36 (= 0) is normal.

車両認識異常を出力した制御系は故障と判断し、故障出力を行う。   The control system that outputs the vehicle recognition abnormality is determined as a failure, and a failure is output.

図３は、車種判別論理が纏めて表形式（表１）に表されている。正常と指示されているケースのみが正常であり、その他のケースは車両認識が異常となる。また、図４は、表１に纏められている車種判別論理に対応した、信号・論理の内容を表形式（表２）に表したものである。   FIG. 3 shows the vehicle type discrimination logic in a tabular form (Table 1). Only cases designated as normal are normal, and in other cases, vehicle recognition is abnormal.
