Description
【発明の詳細な説明】
本発明は、鉄道車両用の自動列車停止装置（ＡＴＳ）や
、定位置停止装置（ＡＴＯ）に於いて、停車目標位［［
までの距離信号等を伝送する方式に関する。[[[
This invention relates to a method for transmitting distance signals, etc.
従来の１８号伝送方式は、一般にｔ周式と呼ばれるもの
が用いられている。The conventional No. 18 transmission system generally uses what is called a t-frequency system.
これは、地上（主として軌道レール間）に、地上子と呼
ばれる電磁共振回路を設置し、車上には、発振回路１ｒ
設置したものであり、車両が地上子の上管通過すると、
車上の発振回路の周波数が変化（これを変周という）す
ること倉用いたもので、この哀周周波数を数種類使用す
ることにより、停止目標点までの距Ｈを区別している。An electromagnetic resonant circuit called a ground element is installed on the ground (mainly between the track rails), and an oscillation circuit 1r is installed on the train.
When a vehicle passes through the upper pipe of the ground coil,
This is because the frequency of the oscillation circuit on the vehicle changes (this is called frequency variation), and by using several types of this frequency, the distance H to the target stop point is distinguished.
駅での定位置停止装置を例にとれば、第１り１に示すこ
と＜、 ３′！＃Ａ類４１ｉ［の地上子が用いられるの
が一般的である。Taking a fixed position stop device at a station as an example, the following is shown in 1. <, 3'! #A class 41i[ ground coils are generally used.
ｉａ軌４であり、２は駅のプラットホーム、３は停止目
標点、４ａ〜４ｃが地上子である。各地上子の仕様及び
相違としては、例えば次のとおりでろる。IA track 4, 2 is the platform of the station, 3 is the stop target point, and 4a to 4c are the ground coils. Specifications and differences of each ground element are as follows, for example.
４ａ：共懺周ｅｔｉ＝ １５０ＫＩ−１ｘ停停止目庇ま
で、２０Ｑｍであることケ示す。4a: Shows that the distance between the two points is 20Qm until the end of the stop.
４ ” 共＠周２ｆｆ＝ １３０ Ｋ Ｈ−ｚ１苧止目
樟点まで、２０ｍ″′ｃめることを示す。4'' common @ circumference 2ff = 130 K H-z1 This indicates that the distance is 20 m'''c to the camphor point.
４Ｃ；共函周彼ｅ＝ １１０ Ｋ Ｈｚ停止目標点まで
、１ｍであること全示す。4C; Conformal box circumference e = 110 K Hz to stop target point, 1m all indicated.
このようｌ従来の方式では、地上子が、電磁的共振回路
、即ち、コイルとコンデンサとの複合部品であるため、
形状が大きく取扱いが不便でめる他、設ｒ１を場所も制
限牙うける。また、経年変化によシ共蛋特性が変化する
こともあシ、保守点検も必襞である。In this conventional method, the ground element is an electromagnetic resonant circuit, that is, a composite component of a coil and a capacitor.
Its large size makes it inconvenient to handle, and there are also restrictions on where it can be installed. In addition, the protein characteristics may change over time, so maintenance and inspection are a must.
一方、車上の発振回路も、電磁的なノイズの影響？受け
やすい上、地上子との結合時間が十分でないと変局され
ないため、車両の速度が制限される等の問題があった。On the other hand, is the oscillation circuit on the car also affected by electromagnetic noise? In addition to being easy to receive, the station cannot be changed unless the connection time with the ground transducer is sufficient, which poses problems such as restricting the speed of the vehicle.
本発明の目的は、地上子を小形・軽蓋にする信置磁的な
ノイズ、経年変化等の影＊ｆｒ受けにくい信号伝送方式
全提供することにある。An object of the present invention is to provide a complete signal transmission system that makes the ground element small and lightweight and is less susceptible to the effects of magnetic noise, aging, etc.
本発明ｅま、光学的像の妓何学的形状に特徴を持たせた
標識全地上子として用い、これを、車上で光学的に受信
し、１ｌｋｌ像昭赦技術により、地上子の種類會判別す
るものである。In the present invention, the optical image is used as a marker with a characteristic geometrical shape, and this is optically received on a vehicle, and the type of ground beam is It is to judge the meeting.
本発明の一実施ψＩＪ？示せは、次のとおりでめる。One implementation of the present invention ψIJ? It can be shown as follows.
地上子の地上への配列方法は、第１図に示した従来例と

っている。The method of arranging the ground element on the ground is the same as the conventional example shown in FIG. 1, but the configuration of the ground element is as shown in FIGS. 2 to 4. That is, mark #4ati
Circle figures a and 4b have triangle b, and 4C has rhombus C.
車上装置の構成の概賛會第５図に示す。An overview of the configuration of the on-board device is shown in Figure 5.
５は、テレビカメラ等の撮像装置であシ、これを車両の
床下面にとシ付け、地上子管見る。5 is an imaging device such as a television camera, which is attached to the underfloor of the vehicle to view the ground subtube.
６は、画像認識装置であり、これにより、＊繊の種別を
判定し、その種別倉、定位置停止装置７に与える。この
画像認識装置６については、その祥細の説明ｅよ省略す

すでに公知の技術である。Reference numeral 6 denotes an image recognition device, which determines the type of *fiber and applies it to the type storage and fixed position stop device 7. The details of this image recognition device 6 will be omitted, but it is currently used in assembly work robots, etc.
This is already a known technology.
本方式によれば、地上子は、平面的な標識でよいため、
小形・＠童となり、また、経年劣化の恐れもない。また
