で交叉せしめる交叉点の新規な構成である。[Detailed Description of the Invention] The present invention relates to a guided wireless communication device, and in particular, a novel configuration of a crossing point that allows guide lines to intersect at appropriate sections.

交叉部３を設けてここで交叉せしめて第１図のようにし
て使用する。When communicating between a transmitting/receiving device inside a moving vehicle and on the ground, it is common to install a pair of guide wires along the track and create electromagnetic coupling between the antenna of the in-vehicle device and these guide wires. However, in order to reduce induced noise, increase the balance of the line, or to control various phases, a crossing section 3 is provided and crossed as appropriate, and used as shown in Figure 1. do.

特にその−邦文叉部３を第２図のように拡大してとりだ
してみると、通常は誘導線１，２で発生する電流磁界φ
□、φ２を用いており、この時交叉部３にも磁界φ３が
発生する。In particular, if we enlarge and take out the Japanese prong 3 as shown in Figure 2, we can see that the current magnetic field φ generated in the induction wires 1 and 2 is normal.
□, φ2 are used, and at this time, a magnetic field φ3 is also generated at the intersection portion 3.

しかしφ３を完全に磁界φ１．φ２に対腰直角に保って
これらに影響を与えないようにすることは困難で偏倚性
の水平方向ベクルトが残って磁界φ□、φ２に影響を与
えることとなり、かかる交叉部３が誘導線全体にわたり
多数存すると加算的に誘導線インピーダンスに影響を与
えるばかりか交叉本来の性能が満足できなくなる。However, φ3 is completely replaced by the magnetic field φ1. It is difficult to keep φ2 perpendicular to the waist so as not to affect them, and a biased horizontal vector remains and influences the magnetic fields φ□ and φ2. If there are a large number of them, not only will they additively affect the guiding wire impedance, but the original performance of the crossover will not be satisfactory.

このような点を考慮して種々検討した結果本案ではかか
る交叉部３を構成する場合に２個の誘導線の一部をとも
に線輪状にしてこれら線輪状部分で発生する磁界が互い
に打消し合うように等量で逆向きつまり一方の誘導線１
側の線輪状部分４を右巻き、他方の誘導線２側の線輪状
部分５を左巻きにして両者を同一径に重ね巻きしたもの
で、このような構成により線輪状部分４，５で発生する
磁界φ４．φ５が打消し合って前述の磁界φ１゜φ２に
何等影響を与えないようにしたものである。As a result of various studies taking these points into consideration, in this proposal, when configuring such an intersection 3, parts of the two guide wires are both formed into a ring shape so that the magnetic fields generated in these ring-shaped parts cancel each other out. Equal amounts and opposite directions, that is, one guiding line 1
The ring-shaped part 4 on the side of the guide wire 2 is wound to the right, and the ring-shaped part 5 on the other side of the guide wire 2 is wound to the left, and both are wound overlappingly to the same diameter.With this configuration, the wire ring-shaped part 4 and 5 are wound. Magnetic field φ4. φ5 cancel each other out so as not to have any influence on the above-mentioned magnetic fields φ1° and φ2.

すでに述べたように、誘導線１，２の交叉部３を夫々線
輪状部分４，５として同一径同一巻数を有し、一方４が
左巻きであれば他方５を右巻きにして例えば磁性丸棒６
に巻回支持せしめ機械的且つ電磁的な安定をはかる。As already mentioned, the crossing portions 3 of the guide wires 1 and 2 are wire ring-shaped portions 4 and 5, respectively, having the same diameter and the same number of turns, and if one 4 is left-handed, the other 5 is right-handed, for example, as a magnetic round bar. 6
It is wound around and supported to ensure mechanical and electromagnetic stability.

又巻数は多い程効果があるが限定の必要はない。Also, the larger the number of turns, the more effective it is, but there is no need to limit it.

このようにすることによって線輪状部分４と５とに夫々
流れる電流は対向する部分全部にわたり等量で逆向きと
なり、発生する磁界φ４．φ５が打消し合って等価的に
もφ１．φ２に影響を与えるような方向の磁束φ５のよ
うに直角漏洩磁界を発生せず、又線輪状部分４，５のイ
ンダクタンスも位相が逆なので０となりこのインダクタ
ンス分を無視できる。By doing this, the currents flowing through the ring-shaped portions 4 and 5 are equal and in opposite directions throughout the opposing portions, and a magnetic field φ4. φ5 cancel each other out and equivalently φ1. Unlike the magnetic flux φ5 in the direction that affects φ2, a right-angle leakage magnetic field is not generated, and the inductance of the wire-shaped portions 4 and 5 is also 0 because the phases are opposite to each other, and this inductance can be ignored.

従って磁界φ１ とφ２の成分のみのあたかも誘導線１
，２が線輪状部分４，５をもっていても磁気的には交叉

に互いに逆相となって誘導雑音軽減に太い役立つことに
なる。Therefore, it is as if the guiding wire 1 has only the magnetic field φ1 and φ2 components.
, 2 have ring-shaped portions 4 and 5, they are magnetically separated at the intersection, resulting in an equivalent diagram as shown in FIG. 4, and the current direction is also adjacent to each other at t)t ct d... They are in opposite phase to each other, which greatly helps in reducing induced noise.
