Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a rug provided with signal lines for connection between interfaces.

Conventional configuration and its problems A personal computer installed in the home is used to control a control system for residential equipment for the purpose of controlling security and energy management, lighting, air conditioning, hot water supply, etc. For this purpose, it is necessary to install signal lines within the home to connect the device interfaces. Conventionally, there are two methods for wiring signal lines in the home: burying the signal line in the ceiling, under the floor, or in the wall, and wiring it along the surface of the wall or pillar, etc. In the former case, wiring Construction will be required, especially for existing houses, which will involve expansion and renovation work.

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

The overall wiring and branch signal lines become longer.

In the case of the latter, the appearance may be impaired and the wiring may impair livability.

Furthermore, when wiring signal lines using rugs, due to their structure, thin, flat signal lines are used, rather than being able to squeeze thick cables or signal lines between them. It had the disadvantage that it was impossible.

OBJECT OF THE INVENTION The present invention eliminates the conventional drawbacks as mentioned above,
By converting signals from serial to parallel, the transmission speed on the parallel signal line is slowed down, and by embedding the parallel signal line in a sandwich pattern inside the rug, wiring and branching can be done in a free pattern, making it possible to connect multiple devices relatively freely. The purpose of this is to enable connection in various positions.

Configuration of the Invention In order to achieve the above object, the present invention provides a rug,
A parallel signal line that is sandwiched between the upper layer structure and the lower layer structure of the floor in a sandwich pattern, branches like a bus line, and is made up of a plurality of lines, and connects the parallel signal line to an external signal line. In order to connect a serial/parallel bidirectional signal transmission converter (hereinafter referred to as a serial/parallel converter) and a branch end of a parallel signal line branched in the shape of a bus line within the rug to connect it to an external device. As a part, it is equipped with a signal line for connection between the interface consisting of a connection connector taken out on the surface of the rug. With this configuration, it is possible to connect the serial signal line outside the rug with an external signal line and one information outlet, and to place multiple connectors for connecting external devices on the rug surface, so the signal line can be connected to the outside of the rug. Wiring can be done throughout the room without the need for wiring, eliminating the need for branching external signal lines and installing information outlets according to the number of devices installed, and easily connecting device interfaces to external signal lines via the mat of the present invention. Now I can do it. Furthermore, high-speed signal transmission can be handled by serial-to-parallel conversion. In addition, by providing a control device for signal decoding using a microcomputer as the serial/parallel converter, half-duplex bidirectional transmission is possible by controlling the direction of signal transmission, the start timing of serial/parallel conversion, error processing, etc. made possible.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows a parallel signal line 1 and a parallel signal line connecting connector 2 sandwiched between an upper layer component 8' and a lower layer component 8'' in a sandwich pattern between an upper layer component 8' and a lower layer component 8'' of a carpet 8 as an example of a carpet, and connect them to the surface of the carpet. This figure shows the form taken out.

FIG. 2 shows an embodiment in which an external signal line 3, an information outlet 4, a rug 8, and an interface device 7 are provided. The control signal from the external signal line 3 to the device with interface 7 is transmitted from the information outlet 4 to the serial signal line connection connector 5,
The signal is parallel-converted by the serial/parallel converter 15 through the carpet external signal line 6, and is transmitted from the carpet internal parallel signal line 1 and the parallel signal line connection connector 2 to the interface device 7. The response from the interfaced device 7 follows the reverse course.

FIG. 3 shows an example of the internal configuration of the carpet 8. The serial signal line 6 outside the carpet is converted into parallel by a serial/parallel converter 15.
A parallel signal line 1 is arranged inside the carpet. A parallel signal line 1 in the carpet is wired like a bus line and branched into a plurality of locations, and a parallel signal line connector 2 is connected to the branch end of the branch line, and the connection part is taken out on the carpet surface.

FIG. 4 is a block diagram of a serial/parallel circuit, in which a carpet external serial signal line 6 is connected to a shift buffer 1 via a serial signal line transceiver 9.
0 input/output, parallel signal line 1 in the carpet
is input to and output from the shift buffer 10 via the parallel signal line transceiver 11. The microcomputer 12 has a parallel signal line 1 in the carpet,
Signals from the carpet external serial signal lines 6 are inputted via transceivers, and the signals are monitored, and the transmission direction of the serial signal line transceiver 9 and parallel signal line transceiver 11 and the operation of the shift buffer 10 are controlled. The signal of the external signal line 3 as a serial information line is sent to the serial signal line transceiver 9 via the serial signal line connecting connector 5 and the carpet external serial signal line 6.
The signal is input/output, further converted into a parallel signal by the shift buffer 10, and further input/output to the in-carpet signal line 1 via the parallel signal line transceiver 11. The microcomputer 12 controls the serial/parallel converter by monitoring and decoding the flow of these signals. Normally, the microcomputer 12 monitors the signal on the carpet external serial signal line 6, searches for a synchronization code at the same time as the signal arrives, and only when the synchronization code is detected, it continues to transmit predetermined data. By sampling at the sample time, the data in the shift buffer 10 is converted into parallel data byte by byte, transmitted to the parallel signal line transceiver 11, latched until the next byte arrives, and output as data to the in-carpet parallel signal line 1. The transmission direction of the clock signal transceiver 13 is controlled by the microcomputer 12, and a synchronizing signal for reading data on the parallel signal line 1 is transmitted from the microcomputer 12 to the clock signal line 14. The above series of operations ends upon detection of the END code. A plurality of addresses corresponding to the parallel signal line connector 2 are registered in advance in the microcomputer 12, and if the addresses match after decoding the signal contents, after detecting the END code, the address is connected from the parallel signal line 1 inside the carpet to the outside of the carpet. The signal transmission direction is switched to the serial signal line 6, and a signal from the in-carpet parallel signal line 1 is waited for. A signal from the parallel signal line 1 in the carpet is taken in via the parallel signal line transceiver 11 in synchronization with the synchronization signal of the clock signal line 14, converted into serial by the shift buffer 10, and sent to the carpet external signal line 6 from the external signal line transceiver 9. Sent. The above series of operations is END
The process ends upon detection of the code, and the transmission direction is switched. Also, if there is no response from the in-carpet parallel signal line 1 after a certain period of time has elapsed, the transmission direction is automatically switched from the carpet external serial signal line 6 to the in-carpet parallel signal line 1, and the carpet external serial signal is transmitted. Waiting for reception from line 6. With the above communication control, half-duplex bidirectional transmission is possible, and the main station connected directly to the external signal line 3 as a serial information line and the device connected to the parallel signal line connector 2 of the rug 8 are connected to the slave station. It becomes possible to exchange control signals between the stations and form a control system for housing equipment.

As described above, this embodiment not only simplifies the wiring of signal lines, but also eliminates the drawback that conventional high-speed transmission cables and signal lines could not be buried in the carpet by providing the serial/parallel converter 15. By lowering the transmission speed within the rug and installing a microcomputer for serial/parallel conversion, we were able to achieve advanced bidirectional transmission control in half-duplex bidirectional transmission.

Effects of the Invention As described above, according to the present invention, a serial-to-parallel conversion section that can be sandwiched between the upper and lower components of the rug in a sandwich-like manner is provided, so as to reduce the transmission speed within the rug. The rug is equipped with connectors around the rug, allowing wiring to be done in any pattern and allowing multiple devices to be connected and installed in relatively free locations.
