Description

[Detailed Description of the Invention] The present invention is used for detecting the position of a moving object, transmitting data, etc.

This paper relates to the improvement of cross-guided wireless transmission lines.

In order to detect the position of mobile objects such as cranes and vehicles, and to transmit data between the mobile object and the ground, a guided wireless transmission line is installed along the path of the mobile object, and is connected to the antenna installed on the mobile object. Information and data are being transmitted.

Due to its principle of operation, this transmission line requires a plurality of electric wires to be laid across each other at various pitches.

Conventionally, this transmission line was installed on-site by installing pins at a fixed pitch along the local installation route and hooking insulated wires onto the pins to form a conductor pair, but this method was difficult to work with and It requires a lot of labor, requires many days of on-site work, and has disadvantages such as the installation of a protective cover, which is uneconomical.

In order to solve this drawback, a cable system has been proposed in which the necessary crossed conductor pairs are constructed on a suitable substrate, a protective coating is applied, and a mesh wire is integrated in parallel as a tension member during installation. ing.

However, in this case as well, there are methods in which hooking notches are cut out at a constant pitch on a long FRP substrate, etc., and insulated wires are hung therein, and wire storage grooves are provided in the length direction and in a direction perpendicular to this. Another method is to connect a number of unit plates made of plastic, etc., and wire the electric wires in the grooves.
All of these had drawbacks such as high material costs for the substrate and high molding costs.

This invention was devised with the aim of providing a cable-type cross-guided transmission line that is easy to manufacture and inexpensive, in consideration of various olfactory points. , spacers attached at predetermined intervals in the length direction of the Metsenger wire, and a pair of olfactory conductors wired along a ladder-like unit formed by the Metsenger wire and the spacers. In the guided wireless transmission line, the spacer includes a part of the spacer for keeping the mesenger wires parallel, a mesenger wire holding part provided on both end surfaces of the part of the spacer, and a part of the spacer provided on both sides of the part of the spacer. The guided wireless transmission line is characterized by comprising a U-shaped conductor wiring holding portion.

That is, in order to facilitate the installation work, the present invention uses a cable type cable, and in order to correctly lay the cable on the installation route, it is necessary to incorporate the Metsusenger wire on both sides of the cable. Focusing on the fact that the wire has a slight expansion and contraction and can be used as a pace for practical positioning, we installed spacers at a constant pitch between the two Metsusenger wires to maintain a constant distance. By laying electric wires along the ladder-like unit formed by In addition, wiring can be done without damaging the wires.

An embodiment of the line devised by Shishishita will be further described with reference to the accompanying drawings.

Figures 1 and 2 show an embodiment of spacer 01 installed between two metsenger wires,
This spacer is made of polyethylene, vinyl chloride, polycarbonate, ABS resin, polyester, FRP, FP.
It is made of a derivative such as R rubber and is integrally molded.

Here, 1 is a part of the spacer for keeping the metsenger wire parallel, 2 is the metsenger wire holding part provided on both end surfaces (upper and lower surfaces in the drawing), and 3 is the spacer part 1 on both sides (in the drawing). This is a U-shaped conductor installation holding section provided on the left and right surfaces.

3 and 4, spacers are attached to the mesh wire 4 at predetermined intervals to form a ladder-like unit, electric wires 5 are laid along this unit, and a protective coating 6 is applied to the outermost periphery. 1 shows an example of an inductive wireless transmission line configured as shown in FIG.

That is, by holding the metsenger wire 4 in the metsenger wire holding part 2 of the spacer, a ladder-like unit is formed with the metsenger wire 4 kept parallel, and the conductor laying holding part 2 of the spacer is If the wire 5 is wired using the U-shaped portion, the wire 5 can be wired easily, and the wire 5 will not be damaged since it is curved.

The electric wires 5 are laid one after another in a zigzag pattern while hooking the plurality of electric wires 5 on spacers so as to form a predetermined wiring pattern.

The protective coating 6 is an extrusion coating of vinyl, polyethylene, or the like.

According to the invented line explained above, the minimum amount of material is required, the spacer is small, so the molding cost and molding work cost are low, and the mounting distance can be freely selected, so all wiring can be done easily. It has many advantages, such as being able to be applied to all patterns, making wiring work for cross-guide pairs easy and without damage due to the U-shaped holding part, and being efficient since wiring work can be done from one side of the cable. There is.

Even in the old days, at the installation site, it was only necessary to extend the cable to the specified location and fix it with metsenger wire, which had significant effects such as saving labor and improving reliability at the site. It has great practical value.
