Description

[Detailed description of the invention] The present invention relates to the structure of a transmission line.

Systems have already been invented that use guided radio to detect the position of moving objects such as bogies, cranes, and trains, and to transmit data between moving objects and the ground.

(Public Patent Publication, Japanese Unexamined Patent Publication No. 47-31651, Japanese Patent Application No. 4
8-15825, etc.) According to Japanese Patent Application Laid-open No. 47-31651, as shown in FIG. A numerical address is given, a logarithmic conductor pair is created according to the number of digits of this binary digit, and whether the conductor spacing is open or closed corresponds to binary values (1 and 0), and a conductor pair corresponding to the binary digit is created. A pattern is formed, and changes in this pattern are made to correspond to changes in the coupling level with the mobile antenna to detect the position of the mobile object.

According to Japanese Patent Application No. 15825/1982, as shown in Figure 2,
Similar to the above, the section along the travel path of the moving object that requires position detection is divided into multiple sections, each section is given a binary number address, and a logarithmic conductor pair is assigned according to the number of digits of this binary number. (n pairs)
Then, one pair of reference pairs is provided, and at the boundary of each address, one of the n pairs of logarithms intersects an appropriate pair line, and the in-phase or opposite phase (inversion) of the reference pair corresponds to binary values (1 and 0), respectively. A conductor pattern corresponding to a binary digit is constructed using n pairs of wires, and changes in this pattern are connected to the mobile antenna and n pairs of wires and 1
The position of a moving object is detected in response to a change in the combined phase of a pair of reference pairs.

Conventionally, coated wires were used for the conductor pairs, and insulator support rods were erected along the travel path of the moving object, and the conductor pairs were hooked onto the rods to create a pattern on-site.

Furthermore, dielectric force bars have been placed over a large number of stacked conductor pairs to protect the conductor pairs.

In the embodiment of the present invention shown in FIG. 3, reference numeral 1 denotes a dielectric tape having a ring-shaped wire support portion 2. In the embodiment shown in FIG.

This dielectric tape 1 is manufactured using an extruder, a press machine, etc., but the wire support portion 2 may be attached to a flat dielectric tape.

Reference numeral 3 denotes an insulated wire, and a pair of wires having a pattern as shown in FIG. 1 or 2 described above is inserted into the wire support portion 2.

Reference numeral 4 denotes a dielectric sheath made of polyethylene or vinyl chloride, which is applied by an extruder to the dielectric tape 1 having the wire support portion and the wire 3 stretched thereon.

In addition, as shown in the figure, the heat-shrinkable tube 5 may be placed over the dielectric tape 1 with electric wires stretched thereon and heated to bring it into close contact.

FIG. 4 is also a perspective view of another embodiment of the present invention, which is similar to that shown in FIG. 3, except that the method of attaching the wire support part 6 and the method of extending the wire 3 are changed. .

Note that 20 is a dielectric tape having a ring-shaped wire support portion 6, 3 is an insulated wire, 4 is a dielectric sheath made of polyethylene or vinyl chloride, and 5 is a heat-shrinkable tube.

As described above, according to the present invention, there is no need to erect insulator support rods along the running path, hook conductors on them, and knit patterns at the site as in the past, and the construction work can be completed in a short time and is economical. be.

It also has the advantage of being economical because consistent manufacturing is possible and the conventionally used exterior cover can be replaced with a sheath.
