Description
本考案は、鉄道の保守用車両の追突防止装置に関する。 The present invention relates to a rear-end collision prevention device for a railway maintenance vehicle.
従来、鉄道の保守用車両の追突防止装置として、自車両の進行方向にレーザビームを照射して先行車との距離を測定する方式が提案されている。この追突防止装置は、先行車との距離と自車両の車速に応じて、警報を発し、車両のブレーキ制御を行うものである。
また、引用文献１には、自車両の進行方向にレーザビームを照射して、先行車との距離を測定し、先行車との追突を防止する保守用車両の追突防止装置において、直線区間とカーブ区間のいずれでも、先行車を確実に検出して、追突を防止することが記載されている。
2. Description of the Related Art Conventionally, a method for measuring a distance from a preceding vehicle by irradiating a laser beam in the traveling direction of the host vehicle has been proposed as a rear-end collision prevention device for a railway maintenance vehicle. This rear-end collision prevention device issues a warning and performs vehicle brake control according to the distance from the preceding vehicle and the vehicle speed of the host vehicle.
Further, in Cited Document 1, in a rear-end collision prevention apparatus for a maintenance vehicle that irradiates a laser beam in the traveling direction of the host vehicle, measures a distance from the preceding vehicle, and prevents a rear-end collision with the preceding vehicle, In any curve section, it is described that a preceding vehicle is reliably detected to prevent a rear-end collision.
しかしながら、単に、レーザビームを、鉄道の保守用車両の追突防止装置として利用した場合は、車両から進行方向にレーザビームを照射しても、濃霧等の天候状態が悪い場合は、レーザビームの透過力が低下したり、又はカーブ等の際、路側の不要反射物等を照射して、誤検知するおそれがあった。 However, when a laser beam is simply used as a rear-end collision prevention device for a railway maintenance vehicle, even if the laser beam is irradiated from the vehicle in the traveling direction and the weather condition such as dense fog is bad, the laser beam is transmitted. There is a risk of false detection by irradiating a roadside unnecessary reflector or the like when the force decreases or curves.

When it is determined that the measurement is less than 30 m, in step S10, it is further determined whether the measurement by GPS is less than 50 m, for example, Even if the laser measurement is measured to be less than 30 m due to fog or the like, it is determined whether it is less than 50 m with a 20 m margin added from 30 m by GPS measurement that is not easily affected by fog or the like. The distance can be reliably grasped, and appropriate processing for preventing rear-end collision can be performed.

After turning on the yellow lamp and / or sounding the alarm buzzer, the process returns to step S1. If it is determined in step S5 that the measurement is less than 10 m, it is determined in step S8 whether the laser measurement is less than 10 m. If it is determined that the measurement is less than 10 m, it is further determined in step S9 whether the measurement by GPS is less than 50 m. If it is determined that the distance is less than 50 m, in step S10, the red lamp is turned on, the alarm buzzer is sounded, and / or the brake is activated. After turning on the red lamp, sounding the alarm buzzer, and / or operating the brake, the process returns to step S1. If the laser measurement is not determined to be less than 10 m in step S8 and the GPS measurement is not determined to be less than 50 m in step S6 and step 9, the processing from step S1 is repeated again.
本例によれば、ステップＳ５において、レーザ計測が３０ｍｍ未満〜１０ｍ以上かを判定し、３０ｍ未満〜１０ｍ以上と判定された場合は、更に、ステップＳ６において、ＧＰＳによる計測が５０ｍ未満かを判定することにより、例えば、霧等により、レーザ計測が３０ｍ未満〜１０ｍ以上と計測しても、霧等の影響を受けにくいＧＰＳ計測によって、３０ｍより２０ｍ余裕値を付加した５０ｍ未満であるかを判定することによって、保守用車両間の距離を確実に把握し、追突防止の適正な処理を行うことができる。また、ステップＳ８において、レーザ計測が１０ｍｍ未満かを判定し、１０ｍ未満と判定された場合は、更に、ステップＳ９において、ＧＰＳによる計測が５０ｍ未満かを判定することにより、ステップＳ５、６の場合と同様に、霧等により、レーザ計測が１０ｍ未満と計測しても、霧等の影響を受けにくいＧＰＳ計測によって、５０ｍ未満であるかを判定することによって、保守用車両間の距離を確実に把握し、追突防止の適正な処理を行うことができる。 According to this example, in step S5, it is determined whether the laser measurement is less than 30 mm to 10 m or more. If it is determined that the laser measurement is less than 30 m to 10 m or more, it is further determined in step S6 whether the measurement by GPS is less than 50 m. For example, even if the laser measurement is less than 30 m to 10 m or more due to fog or the like, it is determined whether it is less than 50 m with a 20 m margin added from 30 m by GPS measurement that is not easily affected by fog or the like. By doing so, it is possible to reliably grasp the distance between the maintenance vehicles and perform an appropriate process for preventing a rear-end collision. In step S8, it is determined whether the laser measurement is less than 10 mm. If it is determined that the measurement is less than 10 m, in step S9, it is determined whether the measurement by GPS is less than 50 m. Similarly, even if the laser measurement is less than 10 m due to fog or the like, the distance between maintenance vehicles can be assured by determining whether the measurement is less than 50 m by GPS measurement that is not easily affected by fog or the like. It is possible to grasp and perform appropriate processing for preventing rear-end collision.
