Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to carpets and other rugs provided with signal lines for connection between interfaces.

Conventional configurations and their problems A personal computer installed in the home is used to control residential equipment for the purpose of controlling security, energy management, lighting, air conditioning, hot water supply, etc. This requires wiring of signal lines within the home to connect the device interfaces.

Traditionally, there are two ways to wire signal lines in the home: burying the signal line in the ceiling, under the floor, or in the wall, or wiring it along the surface of the wall or pillar, etc. In the former case, Wiring work is required, and especially in the case of an existing house, it will involve extension and renovation work.

■ Wiring, branch points, and information outlets that serve as connection points for connecting signal lines and interfaces cannot be provided at arbitrary locations.

■ The overall wiring and branch line 41 will be longer.

In the case of the latter, it also has disadvantages such as spoiling the aesthetic appearance and impairing the comfort of living due to the wiring.

Furthermore, when wiring signal lines using a carpet, the structure of the carpet cannot be used to sandwich very thick cables or signal lines, and thin, flat signal lines are used.
High-speed signal transmission had the disadvantage of a two-wire OJ capability due to the characteristics of the line.

Purpose of the Invention The present invention eliminates the above-mentioned conventional drawbacks, increases the apparent transmission speed by converting signal lines from serial to parallel, supports high-speed transmission, and can be embedded in carpets and other mats. The purpose of this technology is to enable wiring and branching in a free pattern to connect multiple devices in a relatively free manner.

``Structure of the Invention'' - In order to achieve the object described above, the present invention provides a carpet or other rug, and a carpet that is sandwiched between an upper layer structure and a lower layer structure of the rug, and that is branched in the shape of a bus route and that has a plurality of rugs. A pair of parallel signal lines, a serial number parallel bidirectional signal transmission converter (hereinafter referred to as serial-parallel converter) for connecting the parallel signal lines to an external signal line, and a bus route-like section divided within the rug. Connect the connection part for connecting to the external signal line to the branch end of the branched parallel signal line,
It has a signal line for connection between interfaces consisting of a connection connector taken out on the surface of the rug. According to this configuration, by connecting the external signal line and the serial signal line outside the rug with one information outlet, Parallel signal line connectors for connecting multiple devices can be placed on the surface of the rug, so signal lines can be routed throughout the room without the need for construction, and branch lines and information outlets can be connected to the outside according to the number of devices installed. This eliminates the need for installation work, and the device interface can now be easily connected to an external signal line via the mat of the present invention. It also has the effect of not losing its high-speed signal transmission function.

In addition, by providing a control device that decodes signals using a microcomputer as a serial/parallel converter, it controls the direction of signal transmission, the start timing of serial e-parallel conversion, error processing, etc., and performs semi-dual bidirectional transmission. made possible.

Figure 3 shows an example of the internal configuration of the carpet (8), in which the serial signal line (6+) outside the carpet is converted into parallel by the serial/parallel converter (1, 51), and the parallel signal line inside the carpet is Line (1) is arranged.

The parallel signal line (1) inside the carpet is wired like a bus line and is branched at multiple locations, and the parallel signal line connector (2) is connected to the branch end of the branch line, and then taken out from the connection point or onto the carpet surface. It is.
