Description

この発明は、道路とレールの両方を走行できる車両を利用したデュアルモード・トランスポート・システムや、ゴムタイヤ式の新交通システムにおける車両検知装置、特に車両検知の信頼性の向上と設備の簡易化に関するものである。 The present invention relates to a dual mode transport system using a vehicle capable of traveling on both roads and rails, and a vehicle detection device in a new rubber tire type traffic system, and more particularly to improvement in reliability of vehicle detection and simplification of equipment. Is.

デュアルモード・トランスポート・システムは、特許文献１に示すように、道路と、道路に連結されたレールを有する軌道の両方を走行するゴムタイヤ駆動システムである。このシステムの地上設備としては、図４に示すように、道路５とレール６及び道路５からレール６とレール６から道路５の走行モードを変換するモード変換領域７を有する。この道路５とレール６の両方を走行する車両１は、図５に示すように、一般のバスと同様に、前後に設けられたゴムタイヤの車輪８，９と、レール６に係合する前ガイド輪１０及び後ガイド輪１１を有する。後の車輪９は、図６（ａ）に示すように、駆動軸１２に連結され、道路５とレール６上で駆動力を与える駆動輪９ａと、道路５にだけ接する外輪９ｂとを有し、前の車輪８は、図６（ｂ）に示すように、レール６には接しないように前ガイド輪１０よりは外側に配置されている。 As shown in Patent Document 1, the dual mode transport system is a rubber tire drive system that travels on both a road and a track having a rail connected to the road. As shown in FIG. 4, the ground equipment of this system includes a road 5 and a rail 6, and a mode conversion area 7 that converts the travel mode of the road 5 from the road 5 to the rail 6 and the rail 6. As shown in FIG. 5, the vehicle 1 that travels on both the road 5 and the rail 6 has rubber tire wheels 8 and 9 provided in the front and rear and a front guide that engages with the rail 6, as in a general bus. It has a wheel 10 and a rear guide wheel 11. As shown in FIG. 6A, the rear wheel 9 includes a driving wheel 9 a that is connected to the driving shaft 12 and applies driving force on the road 5 and the rail 6, and an outer wheel 9 b that contacts only the road 5. The front wheel 8 is disposed outside the front guide wheel 10 so as not to contact the rail 6 as shown in FIG.

この車両１は、道路５上では一般のバスと同様にゴムタイヤの車輪８，９により走行し、軌道７上では前ガイド輪１０と後ガイド輪１１によりレール６に沿って案内しながら後の駆動輪９ａにより走行する。また、道路５からレール６への変換は、モード変換領域７で前後のガイド輪１０，１１を油圧で下降させてレール６に係合させ、前の車輪８を引き上げてレール走行状態にする。レール６から道路５への変換は前の車輪８を下降させて前後のガイド輪１０，１１を引き上げて道路走行状態にする。 The vehicle 1 travels on the road 5 by rubber tire wheels 8 and 9 in the same manner as a general bus, and on the track 7 is driven along the rail 6 by the front guide wheel 10 and the rear guide wheel 11 and drives behind. Travel by wheel 9a. In the conversion from the road 5 to the rail 6, the front and rear guide wheels 10 and 11 are lowered by hydraulic pressure in the mode conversion region 7 and engaged with the rail 6, and the front wheel 8 is pulled up to be in the rail running state. In the conversion from the rail 6 to the road 5, the front wheel 8 is lowered and the front and rear guide wheels 10 and 11 are pulled up to be in a road running state.

このようにゴムタイヤの車輪を使用した新交通システムで車両の位置を検知するために車軸のレール短絡によらないチェックイン・チェックアウト方式を使用した車両検知方法が採用されている。このチェックイン・チェックアウト方式は、地上装置として車両の走行路に沿って閉そく区間毎に車両検知ループコイルを設け、車上装置としてチェックイン信号の送信部を車両の前部に設け、チェックアウト信号の送信部を車両の後部に設けている。そして車両から送信しているチェックイン信号を閉そく区間毎の車両検知ループで受信したときに、その閉そく区間に車両の前部が進入したと判断し、チェックアウト信号を車両検知ループで受信している間、その閉そく区間に車両が存在していると判断している。
特開２００５−６７５９２号公報 As described above, a vehicle detection method using a check-in / check-out method that does not involve a rail short circuit of an axle is employed in order to detect the position of the vehicle in a new transportation system using rubber tire wheels. In this check-in / check-out system, a vehicle detection loop coil is provided for each block section along the road of the vehicle as a ground device, and a check-in signal transmitter is provided at the front of the vehicle as an on-vehicle device. A signal transmitter is provided at the rear of the vehicle. When the check-in signal transmitted from the vehicle is received by the vehicle detection loop for each block section, it is determined that the front part of the vehicle has entered the block section, and the check-out signal is received by the vehicle detection loop. While there is a vehicle, it is determined that there is a vehicle in the closed section.
JP 2005-67592 A

前記のようにデュアルモード・トランスポート・システムやゴムタイヤ式の新交通システムで車両を検知するためにチェックイン・チェックアウト方式を使用すると、閉そく区間毎に車両検知ループを布設する必要があり、その施工が容易でないとともに地上装置と車上装置が高価になってしまう。 If the check-in / check-out method is used to detect the vehicle in the dual mode transport system or the rubber tire type new traffic system as described above, it is necessary to lay a vehicle detection loop for each block section. Construction is not easy, and ground devices and on-vehicle devices become expensive.

この発明は、このような短所を改善し、低コストで容易に施工することができるとともに信頼性と安全性を高めることができる車両検知装置を提供することを目的とするものである。 An object of the present invention is to provide a vehicle detection device that can improve such disadvantages, can be easily constructed at low cost, and can improve reliability and safety.

この発明の車両検知装置は、車両が走行する走行路の各閉そく区間の境界点にはそれぞれ設けられ、常時閉形の接点を有し、車両を検知する２系統の車軸検知器と、各閉そく区間の境界点に設けられた２系統の常時閉形の接点が接続された車両検知部とを有し、車両検知部は、各閉そく区間に車両が進入したことを検知する進入検知部と、各閉そく区間に車両が在線することを検知する在線検知部を有し、進入検知部は、閉そく区間毎に各車軸検知器の接点に接続され、車両が該当する閉そく区間に進入したことを示す車両進入信号を出力する２系統の進入検知リレーと、該２系統の進入検知リレーのいずれか一方で車両進入信号を出力したときに該当する閉そく区間に対する進入側の閉そく区間から車両が進出したことを示す車両進出信号を出力する進出検知リレーとを有し、在線検知部は２系統の進入検知リレーのいずれか一方で車両進入信号を出力したときに該当する閉そく区間に車両が在線することを示す車両在線信号を出力して保持し、該当する閉そく区間より車両進出側の閉そく区間の進出検知リレーから車両進出信号が出力されたとき車両在線信号の保持を解除する軌道リレーを有することを特徴とする。 The vehicle detection device according to the present invention is provided at each boundary point of each block section of the travel path on which the vehicle travels, has two normally-closed contacts, detects two-axle detectors, and each block section A vehicle detection unit connected to two normally closed contacts provided at a boundary point of the vehicle, the vehicle detection unit detecting an entry of a vehicle into each block section, and each block There is an on-line detection unit that detects that a vehicle is in the section, and the entry detection unit is connected to the contact of each axle detector for each block section and indicates that the vehicle has entered the corresponding block section It indicates that the vehicle has advanced from the block section on the approach side with respect to the corresponding block section when the vehicle approach signal is output by one of the two systems of the line detection relay and the two systems of the line detection relay. Vehicle advance signal The presence line detection unit outputs a vehicle presence line signal indicating that the vehicle is present in the corresponding block section when the vehicle entry signal is output by one of the two systems of entry detection relays. And a track relay for releasing the holding of the vehicle presence signal when a vehicle advance signal is output from the advance detection relay in the closed zone on the vehicle advance side from the corresponding closed zone.

この発明は、車両が走行する走行路の各閉そく区間の境界点に設けた２系統の車軸検知器で車両を検知することにより、車両の走行路に沿った地上設備を簡略化して設備費用を低減することができる。 This invention simplifies the ground equipment along the traveling path of the vehicle by detecting the vehicle with two axle detectors provided at the boundary points of the respective closed sections of the traveling path on which the vehicle travels, thereby reducing the equipment cost. Can be reduced.

また、２系統の車軸検知器で車両を検知したときに、該当する閉そく区間に車両が進入したと判定することにより、車両検知の信頼性を高めることができる。 Further, when the vehicle is detected by two axle detectors, it is possible to improve the reliability of vehicle detection by determining that the vehicle has entered the corresponding block section.

さらに、２系統の車軸検知器からの信号により車両が進入側の閉そく区間から進出したことを検知して、進入側の閉そく区間の車両在線信号を断にするから、各閉そく区間に車両が在線しているか否を高信頼度で検知することができ、簡単な構成で安全性を確保することができる。 Furthermore, since the signal from the two axle detectors detects that the vehicle has advanced from the approach-side block section and cuts off the vehicle-side signal in the approach-side block section, the vehicle is in each block section. It is possible to detect whether or not it is performed with high reliability, and it is possible to ensure safety with a simple configuration.

図１はこの発明の車両検知装置の構成図である。例えば、デュアルモード・トランスポート・システムの車両１が走行する走行路２の各閉そく区間１Ｔ〜４Ｔの境界点にはそれぞれ２個１組の車軸検知器Ｗｉａ，Ｗｉｂ（ｉ＝２〜４）が設けられている。この２個１組の車軸検知器Ｗｉａ，Ｗｉｂには、それぞれ常時閉で車両１の車軸を検知したときに開となる動作接点を有し、各動作接点は制御装置３の車両検知部４に接続されている。 FIG. 1 is a block diagram of a vehicle detection apparatus according to the present invention.

Is provided. Each set of two axle detectors Wia and Wib has operation contacts that are normally closed and open when the axle of the vehicle 1 is detected. Each operation contact is connected to the vehicle detection unit 4 of the control device 3. It is connected.

車両検知部４には、例えば図２の閉そく区間２Ｔと閉そく区間３Ｔの車両１の有無を検知する回路構成図に示すように、閉そく区間２Ｔの進入検知部は、車軸検知器Ｗ２ａの常時閉の動作接点Ｗ２ａに接続され、車両１が閉そく区間２Ｔに進入したことを示す信号を送り出す進入検知リレー２Ｔ−ＩＮａと、車軸検知器Ｗ２ｂの常時閉の動作接点Ｗ２ｂに接続され、車両１が閉そく区間２Ｔに進入したことを示す信号を送り出す進入検知リレー２Ｔ−ＩＮｂ及び並列に接続された進入検知リレー２Ｔ−ＩＮａと進入検知リレー２Ｔ−ＩＮｂの復旧接点２Ｔ−ＩＮａ，２Ｔ−ＩＮｂに接続されて車両１が閉そく区間１Ｔから進出したことを示す信号を送り出す進出検知リレー１Ｔ−ＯＵＴを有する。閉そく区間３Ｔの進入検知部は、車軸検知器Ｗ３ａの常時閉の動作接点Ｗ３ａに接続され、車両１が閉そく区間３Ｔに進入したことを示す信号を送り出す進入検知リレー３Ｔ−ＩＮａと、車軸検知器Ｗ３ｂの常時閉の動作接点Ｗ３ｂに接続され、車両１が閉そく区間３Ｔに進入したことを示す信号を送り出す進入検知リレー３Ｔ−ＩＮｂと、並列に接続された進入検知リレー３Ｔ−ＩＮａと進入検知リレー３Ｔ−ＩＮｂの復旧接点３Ｔ−ＩＮａ，３Ｔ−ＩＮｂに接続されて車両１が閉そく区間２Ｔから進出したことを示す信号を送り出す進出検知リレー２Ｔ−ＯＵＴを有する。閉そく区間４Ｔの進入検知部には、車軸検知器Ｗ４ａの常時閉の動作接点Ｗ４ａに接続され、車両１が閉そく区間４Ｔに進入したことを示す信号を送り出す進入検知リレー４Ｔ−ＩＮａと、車軸検知器Ｗ４ｂの常時閉の動作接点Ｗ４ｂに接続され、車両１が閉そく区間４Ｔに進入したことを示す信号を送り出す進入検知リレー４Ｔ−ＩＮｂと、並列に接続された進入検知リレー４Ｔ−ＩＮａと進入検知リレー４Ｔ−ＩＮｂの復旧接点４Ｔ−ＩＮａ，４Ｔ−ＩＮｂに接続されて車両１が閉そく区間３Ｔから進出したことを示す信号を送り出す進出検知リレー３Ｔ−ＯＵＴを有する。閉そく区間２Ｔの在線検知部には、直列に接続された進入検知リレー２Ｔ−ＩＮａと進入検知リレー２Ｔ−ＩＮｂ及び進出検知リレー２Ｔ−ＯＵＴの動作接点２Ｔ−ＩＮａ，２Ｔ−ＩＮｂ，２Ｔ−ＯＵＴに接続され車両１が閉そく区間２Ｔに在線することを示す信号を送り出す軌道リレー２Ｔ−ＴＲを有し、閉そく区間３Ｔの在線検知部には、直列に接続された進入検知リレー３Ｔ−ＩＮａと進入検知リレー３Ｔ−ＩＮｂ及び進出検知リレー３Ｔ−ＯＵＴの動作接点３Ｔ−ＩＮａ，３Ｔ−ＩＮｂ，３Ｔ−ＯＵＴに接続され車両１が閉そく区間３Ｔに在線することを示す信号を送り出す軌道リレー３Ｔ−ＴＲを有する。この在線検知部の進出検知リレー２Ｔ−ＯＵＴの動作接点２Ｔ−ＯＵＴには軌道リレー２Ｔ−ＴＲの動作接点２Ｔ−ＴＲとプリセットスイッチＰＢが並列に接続され、進出検知リレー３Ｔ−ＯＵＴの動作接点３Ｔ−ＯＵＴには軌道リレー３Ｔ−ＴＲの動作接点３Ｔ−ＴＲとプリセットスイッチＰＢが並列に接続されている。そしてプリセットスイッチＰＢをオンにすると、進入検知リレー２Ｔ−ＩＮａ，２Ｔ−ＩＮｂ及びプリセットスイッチＰＢを介して軌道リレー２Ｔ−ＴＲのコイルが励磁され、動作接点２Ｔ−ＴＲにより自己保持して軌道リレー２Ｔ−ＴＲが常時動作状態になり、同様にして軌道リレー３Ｔ−ＴＲも常時動作状態になっている。 For example, as shown in the circuit configuration diagram for detecting the presence or absence of the vehicle 1 in the closing section 2T and the closing section 3T in FIG. 2, the approach detection section in the closing section 2T is normally closed with the axle detector W2a. Connected to the operation contact W2a of the vehicle, and is connected to an ingress detection relay 2T-INa that sends a signal indicating that the vehicle 1 has entered the block section 2T, and a normally closed operation contact W2b of the axle detector W2b. Connected to the intrusion detection relay 2T-INb that sends a signal indicating that the vehicle has entered the section 2T, the intrusion detection relay 2T-INa connected in parallel, and the recovery contacts 2T-INa and 2T-INb of the intrusion detection relay 2T-INb There is an advance detection relay 1T-OUT that sends out a signal indicating that the vehicle 1 has advanced from the closed section 1T. The approach detection unit in the block section 3T is connected to the normally closed operation contact W3a of the axle detector W3a, and an entrance detection relay 3T-INa for sending a signal indicating that the vehicle 1 has entered the block section 3T, and the axle detector. An intrusion detection relay 3T-INb connected to the normally closed operation contact W3b of W3b and sending a signal indicating that the vehicle 1 has entered the block section 3T, and an intrusion detection relay 3T-INa and an intrusion detection relay connected in parallel There is an advance detection relay 2T-OUT that is connected to 3T-INb recovery contacts 3T-INa and 3T-INb and sends a signal indicating that the vehicle 1 has advanced from the block section 2T. An entrance detection relay 4T-INa that is connected to the normally closed operation contact W4a of the axle detector W4a and sends a signal indicating that the vehicle 1 has entered the block section 4T is connected to the approach detection section of the block section 4T, and an axle detection An intrusion detection relay 4T-INb connected to the normally closed operation contact W4b of the device W4b and sending a signal indicating that the vehicle 1 has entered the block section 4T, and an intrusion detection relay 4T-INa connected in parallel with the ingress detection There is an advance detection relay 3T-OUT which is connected to the recovery contacts 4T-INa and 4T-INb of the relay 4T-INb and sends out a signal indicating that the vehicle 1 has advanced from the block section 3T. The in-line detection unit of the block section 2T includes an operation detection contact 2T-INa, 2T-INb, and 2T-OUT of the ingress detection relay 2T-INa and the ingress detection relay 2T-INb and the advance detection relay 2T-OUT connected in series. It has a track relay 2T-TR that sends out a signal indicating that the vehicle 1 is in the closed section 2T, and the in-line detector in the closed section 3T has an ingress detection relay 3T-INa and an ingress detection connected in series. The track relay 3T-TR is connected to the operation contacts 3T-INa, 3T-INb, and 3T-OUT of the relay 3T-INb and the advance detection relay 3T-OUT, and sends a signal indicating that the vehicle 1 is in the block section 3T. . An operation contact 2T-OUT of the track relay 2T-TR and a preset switch PB are connected in parallel to the operation contact 2T-OUT of the advance detection relay 2T-OUT of the presence detection unit, and the operation contact 3T of the advance detection relay 3T-OUT. The operation contact 3T-TR of the track relay 3T-TR and the preset switch PB are connected in parallel to -OUT. When the preset switch PB is turned on, the coil of the track relay 2T-TR is excited via the entry detection relays 2T-INa and 2T-INb and the preset switch PB, and is self-held by the operation contact 2T-TR and is switched to the track relay 2T. -TR is always in an operating state, and similarly, the track relay 3T-TR is also always in an operating state.

この車両検知装置で、例えば車両１が閉そく区間１Ｔから閉そく区間２Ｔに進入して閉そく区間２Ｔから進出したときの動作を図３のタイムチャートを参照して説明する。 The operation of the vehicle detection device when the vehicle 1 enters the closing section 2T from the closing section 1T and advances from the closing section 2T will be described with reference to the time chart of FIG.

車両１が閉そく区間１Ｔから閉そく区間２Ｔに進入すると、閉そく区間２Ｔの進入側に設けた２系統の車軸検知器Ｗ２ａ，Ｗ２ｂが車両１を検知して復旧し、常時閉の動作接点Ｗ２ａと常時閉の動作接点Ｗ２ｂが開になり、進入検知リレー２Ｔ−ＩＮａと進入検知リレー２Ｔ−ＩＮｂのコイルを無励磁にして進入検知リレー２Ｔ−ＩＮａと進入検知リレー２Ｔ−ＩＮｂを復旧させ、車両１が閉そく区間２Ｔに進入したことを示す信号を送り出す。このように２系統の車軸検知器Ｗ２ａ，Ｗ２ｂで車両１を検知するから、車両検知の信頼性を高めることができる。 When the vehicle 1 enters the closing zone 2T from the closing zone 1T, the two axle detectors W2a and W2b provided on the entry side of the closing zone 2T detect and recover the vehicle 1, and the normally closed operation contact W2a is always The closed operation contact W2b is opened, the coils of the entry detection relay 2T-INa and the entry detection relay 2T-INb are de-energized to restore the entry detection relay 2T-INa and the entry detection relay 2T-INb. A signal indicating that the vehicle has entered the block section 2T is sent out. Thus, since the vehicle 1 is detected by the two axle detectors W2a and W2b, the reliability of vehicle detection can be improved.

進入検知リレー２Ｔ−ＩＮａと進入検知リレー２Ｔ−ＩＮｂが復旧して軌道リレー２Ｔ−ＴＲのコイルに直列に接続されている動作接点２Ｔ−ＩＮａ，２Ｔ−ＩＮｂが開になると軌道リレー２Ｔ−ＴＲのコイルを無励磁にして軌道リレー２Ｔ−ＴＲから閉そく区間２Ｔに車両１が在線することを示す信号を送り出す。このように２系統の進入検知リレー２Ｔ−ＩＮａ，２Ｔ−ＩＮｂのいずれもが復旧して動作接点２Ｔ−ＩＮａ，２Ｔ−ＩＮｂが開になったときに、閉そく区間２Ｔに車両１が進入して在線することを検知するから信頼性を高めることができる。 When the ingress detection relay 2T-INa and the intrusion detection relay 2T-INb are restored and the operation contacts 2T-INa and 2T-INb connected in series to the coil of the trajectory relay 2T-TR are opened, the trajectory relay 2T-TR A signal indicating that the vehicle 1 is in the closed section 2T is sent from the track relay 2T-TR by de-energizing the coil. As described above, when both the two systems of the entry detection relays 2T-INa and 2T-INb are restored and the operation contacts 2T-INa and 2T-INb are opened, the vehicle 1 enters the closed section 2T. The reliability can be improved because the presence of a line is detected.

また、進入検知リレー２Ｔ−ＩＮａと進入検知リレー２Ｔ−ＩＮｂが復旧して進出検知リレー１Ｔ−ＯＵＴに接続されている復旧接点２Ｔ−ＩＮａと復旧接点２Ｔ−ＩＮｂのいずれもが閉になると、進出検知リレー１Ｔ−ＯＵＴのコイルを励磁して車両１が閉そく区間１Ｔから進出したことを示す信号を送り出す。 Further, when the ingress detection relay 2T-INa and the ingress detection relay 2T-INb are restored and both the restoration contact 2T-INa and the restoration contact 2T-INb connected to the advancement detection relay 1T-OUT are closed, the advancement is performed. A signal indicating that the vehicle 1 has advanced from the closing section 1T is sent out by exciting the coil of the detection relay 1T-OUT.

この状態で閉そく区間２Ｔに進入した車両１が走行して閉そく区間３Ｔに進入すると、閉そく区間３Ｔの進入側に設けた２系統の車軸検知器Ｗ３ａ，Ｗ３ｂが車両１を検知して復旧し、常時閉の動作接点Ｗ３ａと常時閉の動作接点Ｗ３ｂが開になり、進入検知リレー３Ｔ−ＩＮａ，３Ｔ−ＩＮｂのコイルを無励磁にして車両１が閉そく区間３Ｔに進入したことを示す信号を送り出す。進入検知リレー３Ｔ−ＩＮａ，３Ｔ−ＩＮｂが復旧して軌道リレー３Ｔ−ＴＲのコイルに直列に接続されている動作接点３Ｔ−ＩＮａ，３Ｔ−ＩＮｂが開になると軌道リレー３Ｔ−ＴＲのコイルを無励磁にして軌道リレー３Ｔ−ＴＲを復旧させて、軌道リレー３Ｔ−ＴＲから閉そく区間３Ｔに車両１が在線することを示す信号を送り出す。また、進入検知リレー３Ｔ−ＩＮａ，３Ｔ−ＩＮｂが復旧して進出検知リレー２Ｔ−ＯＵＴに接続されている復旧接点３Ｔ−ＩＮａ，３Ｔ−ＩＮｂのいずれもが閉になると進出検知リレー２Ｔ−ＯＵＴのコイルを励磁して車両１が閉そく区間２Ｔから進出したことを示す信号を送り出す。このとき軌道リレー２Ｔ−ＴＲに接続された進入検知リレー２Ｔ−ＩＮａ，２Ｔ−ＩＮｂの動作接点２Ｔ−ＩＮａ，２Ｔ−ＩＮｂは閉となっているから進出検知リレー２Ｔ−ＯＵＴが動作して動作接点２Ｔ−ＯＵＴが閉になると軌道リレー２Ｔ−ＴＲのコイルを励磁して閉そく区間２Ｔの車両在線信号を断にする。車両１が閉そく区間３Ｔを進行して閉そく区間４Ｔに進入したときも、同様にして軌道リレー３Ｔ−ＴＲのコイルを励磁して閉そく区間３Ｔの車両在線信号を断にする。 In this state, when the vehicle 1 entering the block section 2T travels and enters the block section 3T, the two axle detectors W3a and W3b provided on the entry side of the block section 3T detect the vehicle 1 and recover. The normally-closed operation contact W3a and the normally-closed operation contact W3b are opened, and the coils of the entry detection relays 3T-INa and 3T-INb are de-energized to send a signal indicating that the vehicle 1 has entered the block section 3T. . When the ingress detection relays 3T-INa and 3T-INb are restored and the operation contacts 3T-INa and 3T-INb connected in series to the coil of the track relay 3T-TR are opened, the coil of the track relay 3T-TR is not used. The track relay 3T-TR is restored by excitation, and a signal indicating that the vehicle 1 is in the closed section 3T is sent from the track relay 3T-TR. In addition, when the entry detection relays 3T-INa and 3T-INb are restored and the recovery contacts 3T-INa and 3T-INb connected to the advance detection relay 2T-OUT are closed, the advance detection relay 2T-OUT The coil 1 is excited to send out a signal indicating that the vehicle 1 has advanced from the closing section 2T. At this time, since the operation contacts 2T-INa and 2T-INb of the ingress detection relays 2T-INa and 2T-INb connected to the track relay 2T-TR are closed, the advance detection relay 2T-OUT operates and the operation contacts When 2T-OUT is closed, the coil of the track relay 2T-TR is excited to cut off the vehicle presence line signal in the closing section 2T. Similarly, when the vehicle 1 travels through the closing section 3T and enters the closing section 4T, the coil of the track relay 3T-TR is similarly excited to cut off the vehicle presence signal in the closing section 3T.

このように２系統の車軸検知器Ｗ３ａ，Ｗ３ｂからの信号により車両１が閉そく区間２Ｔから進出したことを検知して、閉そく区間２Ｔの車両在線信号を断にするから、閉そく区間２に車両１が在線しているか否を高信頼度で検知することができる。 As described above, the signal from the two axle detectors W3a and W3b detects that the vehicle 1 has advanced from the block section 2T, and the vehicle on-line signal in the block section 2T is cut off. It is possible to detect with high reliability whether or not there is a line.

また、車両１が閉そく区間３Ｔを進行して閉そく区間４Ｔに進入したときも、同様にして軌道リレー３Ｔ−ＴＲのコイルを励磁して閉そく区間３Ｔの車両在線信号を断にする。 Similarly, when the vehicle 1 travels through the closing section 3T and enters the closing section 4T, the coil of the track relay 3T-TR is similarly excited to cut off the vehicle presence signal in the closing section 3T.

前記説明ではデュアルモード・トランスポート・システムにおいて車両１を検知する場合について示したが、ゴムタイヤ式の新交通システムにも同様に適用することができる。 In the above description, the case where the vehicle 1 is detected in the dual mode transport system has been described. However, the present invention can be similarly applied to a rubber tire type new transportation system.

Two axle detectors that are provided at the boundary points of each closed section of the travel path on which the vehicle travels, have normally closed contacts and detect the vehicle, and 2 provided at the boundary points of each closed section A vehicle detection unit connected to a normally closed contact of the system,
The vehicle detection unit includes an entry detection unit that detects that a vehicle has entered each block section, and a line detection unit that detects that a vehicle is in each block section,
The approach detection unit is connected to a contact point of each axle detector for each block section, and outputs two approach detection relays that output a vehicle approach signal indicating that the vehicle has entered the corresponding block section. An advance detection relay that outputs a vehicle advance signal indicating that the vehicle has advanced from the approach-side block section with respect to the corresponding block section when outputting a vehicle approach signal on either of the entry detection relays;
The on-line detection unit outputs and holds a vehicle on-line signal indicating that the vehicle is on the corresponding block section when the vehicle approach signal is output on one of the two systems of entry detection relays, and the corresponding block section A vehicle detection apparatus comprising a track relay for releasing the holding of the vehicle presence line signal when a vehicle advance signal is output from an advance detection relay in a closed section closer to the vehicle advance side.
