本考案は海水中で信号伝送を行なうインダクタ
ンス補償型伝送装置に関するものである。[Detailed Description of the Invention] The present invention relates to an inductance-compensated transmission device for transmitting signals in seawater.

ことがある。 In conventional signal transmission devices such as disposable buoys, the transmission line with an oscillator attached is wrapped around a reel and floated in the sea, and the transmission line is sequentially let out from the reel. As the length of the wrapped transmission line changes, the inductance of the transmission line changes. This may affect the transmission band.

１中の接地電極を示す。 This will be explained in detail with reference to the schematic diagram of the transmission device shown in FIG. In the figure, 1 is a transmission line, 2 is a winding frame of the transmission line 1, 3 is an output terminal for an AC signal, 4 is an oscillator, 5 is an amplifier, 6 is a separation circuit for the AC signal and DC power supply on the transmission side, 7 is a DC power supply, 8 is a separation circuit for the receiving side AC signal and DC power supply, 9 is an AC load impedance Z 1 (Ω), and 10 is seawater 1

が変化するようになる。 In such a transmission device, by winding the transmission line 1 around the winding frame 2, the winding frame 2 is proportional to the square of the number of windings.
An inductance L(H) proportional to the magnetic permeability of is generated,
Its impedance is jωL (Ω). When the DC resistance of the transmission line 1 is R 0 (Ω), this transmission characteristic becomes Z 1 /R 0 +jωL + Z 1 , and as the transmission line 1 becomes longer, the number of turns increases, or the transmission frequency becomes higher, (Z 1 +R 0 )＜
jωL, and the transmission characteristic becomes Z 1 /R 0 +jωL+Z 1 ≒Z 1 /jωL. Therefore, the transmission characteristics change depending on the length of the transmission line (change in inductance) and the transmission frequency.

つた。 In other words, as shown in Fig. 2, the inductance shown on the vertical axis changes depending on the length of the transmission line 1 taken on the horizontal axis, and as shown in Fig. 3, the inductance shown on the vertical axis changes. Losses change. Furthermore, as shown in FIG. 4, there is a problem in that as the frequency on the horizontal axis increases, the transmission loss on the vertical axis increases. Another drawback is that it requires AC/DC separation circuits on the transmitting and receiving sides, making the circuit configuration complicated.

It is equipped with transmission lines for DC power supply. An embodiment of the present invention will be described in detail below with reference to the drawings.

2 and the transmission line 13 operate as a transformer with the transmission line 12 as the primary winding and the transmission line 13 as the secondary winding. The impedance on the winding (transmission line 12) side will be explained with reference to FIG.

is the DC resistance R 0 (Ω) of the transmission line 12, 17 is the secondary winding of the transmission line 13, and 18 is the series connection impedance Z 2 (Ω) of the AC impedance of the power supply circuit and the DC resistance of the transmission line 13. The primary winding of the transmission line 12 and the secondary winding of the transmission line 13 each have a self-inductance L(H) proportional to the square of the number of turns, and a mutual inductance M(H) between the primary and secondary windings. H).
したがつて１次巻線（伝送線１２）側電圧VT1
と電流IT1の関係はトランスの原理から次式のよ
うになる。 Therefore, the voltage on the primary winding (transmission line 12) side V T1
The relationship between I and current I T1 is expressed by the following equation based on the principle of a transformer.
VT1＝１／nkVT2＋jω１−k2／k2MIT2 IT1＝１／jωMVT2＋ｎ／ｋIT2 ここで VT2は２次巻線１７の誘起電圧 IT2は２次巻線１７に流れる電流 ｎは１次巻線１５と２次巻線１７の巻数比 ｋは比例定数でＭ＝kLの関係にある。 V T1 = 1/nkV T2 +jω1-k 2 /k 2 MI T2 I T1 = 1/jωMV T2 +n/kI T2 where V T2 is the induced voltage in the secondary winding 17 I T2 flows into the secondary winding 17 The current n is the turns ratio between the primary winding 15 and the secondary winding 17, and k is a proportionality constant with the relationship M=kL.

スZ2との並列接続となる。 In the circuit of the present invention, the transmission line 12 and the transmission line 13 are one
Since the coils are simultaneously wound around two winding frames 2, the turns ratio of the primary winding and the secondary winding are the same, and there is almost no leakage flux, n=1 and k≒1. Therefore, V T1 = V T2 I T1 ≒ 1/jωLV T2 + I T2 , and by modifying the equation using the load impedance Z 2 of the secondary winding 17, the impedance Z T1 on the primary winding 15 side becomes Z T1 = V T1 /I T1 = 1/1/jωL+1/Z 2 . As a result, the primary impedance Z T1 of the transformer becomes a parallel connection of the impedance jωL due to the self-inductance of the transmission line 12 and the secondary load impedance Z 2 .
従つてZ2≪jωLの条件にすると
ZT1≒Z2

比べ大巾に改善されていることが理解される。 Therefore, under the condition that Z 2 ≪jωL, Z T1 ≒Z 2 and the primary impedance of the transformer is almost independent of the self-inductance of the transmission line 12 (the extended length of the transmission line 12). FIG. 7 is a graph showing the effect of the primary impedance of the transformer. The horizontal axis is the length of the transmission line 12 and the transmission line 13, and the vertical axis is the primary impedance Z T1 of the transformer. It can be seen that this is a significant improvement compared to the single-line case in the example.
Z2≪jωLの条件は本考案の如く伝送線１３に直
流定電圧電源を接続することにより容易に実現出
来、このときの伝送特性は
Z1／Z1＋ZT1＋R0≒Z1／Z1＋Z2＋R0
となり伝送線１２の繰り出し長さに依存しない
ようになる。 The condition of Z 2 ≪jωL can be easily achieved by connecting a DC constant voltage power supply to the transmission line 13 as in the present invention, and the transmission characteristics at this time are Z 1 /Z 1 +Z T1 +R 0 ≒Z 1 /Z 1 +Z 2 +R 0 and becomes independent of the length of the transmission line 12.

解される。 FIG. 8 is a graph showing the effect of transmission loss of the above-mentioned transmission device. The horizontal axis shows the length of the transmission line 12 and the transmission line 13, and the vertical axis shows the transmission loss. It can be seen that the case of this example shown by the solid line is much improved compared to the case of the case.

になる等の効果もある。 As explained above, in this invention, it is necessary to prepare a transmission line separate from the AC signal transmission line for inductance compensation and connect a circuit with low AC impedance, so the structure is such that constant voltage DC power is transmitted at the same time. . Therefore, the DC power supply circuit is independent, and there is no need for a separation circuit between the AC signal and the DC power supply on the transmitting and receiving sides, which has the effect of simplifying the circuit configuration and circuit design. Moreover, since no voltage drop occurs due to the separation circuit, there is an advantage that DC voltage can be used effectively. Furthermore, since the inductance compensation effect is not affected by the material of the winding frame, there is also an effect that selection of the material of the winding frame becomes easy.
