Description

  The present invention relates to a functional device used in a wiring system that can both transmit an information signal and supply power to a load.

  Conventionally, in a system that performs load operation (monitoring) control through a terminal device, a transmission signal composed of a bipolar baseband signal is sent from the central monitoring device to the terminal device by time division multiplexing, and each terminal device transmits this transmission signal. There has been a system for exchanging information and obtaining power for the terminal circuit unit (Patent Document 1).

  In this system, a switch box standardized for an embedded wiring device and an operation terminal provided with an operation switch or the like using a mounting frame corresponding to the switch box are embedded in a wall surface. It is designed to be used in the same way as a wall switch. When installing two sets of operation terminals, use a double mounting frame with two mounting windows, attach a series of one side of the mounting frame to a series of switch boxes, and attach the other side to the wall. It has been arranged so that the two operation terminals are provided side by side by arranging the operation terminals on the respective mounting windows. In addition, a signal from one operating terminal (switch box side) to the other operating terminal can be obtained by bringing the conductive pieces provided between the mounting windows into contact with the lead pieces of the operating terminal provided on the mounting windows on both sides. It is configured to feed and wire the wires.

  By the way, in such a conventional system, although power can be supplied to the terminal circuit unit of the terminal device by the transmission signal, for example, power supply to the load controlled by the control terminal device due to limitation of the current capacity of the signal line, etc. Was configured to be supplied from commercial power at each installation location. Therefore, since it is only necessary to connect two signal lines between the terminals, it is possible to reduce the wiring of the signal lines, but since the wiring of the power supply line to the load remains as before, the control terminal There was a problem that the installation location of the was limited.

  Therefore, in order to solve such a problem, a basic function module that is fixed to the construction surface and performs power supply and information transmission / reception via a previously wired power line and information line, and the basic function module A wiring system using an extended function module that is arranged on the construction surface and at least one of power supply and information signal transmission through the basic function module has been proposed. The power path and the information path can be secured in the extended function module simply by connecting the extended function module to the function module.

Here, when power is supplied and an information signal is transmitted between the basic function module and the extended function module arranged in parallel on the construction surface, one side surface (for example, the right side surface) of the basic function module serving as the power input side. In addition to providing the connection terminals on the convex side, the connection terminals on the concave side are provided on the contact surface (left side) on the extended function module side that is the power output side. The connection between the functional modules has been performed by connecting the provided connection terminals to each other in a concave-convex manner.

  In the wiring system using the functional device of the present invention, as a method for transmitting the information signal, either baseband transmission or broadband transmission may be adopted, and any protocol may be used, but audio, video, etc. are used. Audio and video are transmitted to and from the interphone main unit and sub unit based on JT-H232 packets. In the control system, one or more loads are applied depending on operation data from the operation side. A routing protocol corresponding to unicast or broadcast capable of one-to-one correspondence or one-to-N correspondence that can be operated may be adopted, and is not particularly limited, and thus description thereof is omitted. Further, the protocol used in the gate device 1 may be different from the protocol used between the gate devices 1 and the protocol used in the functional modules 4 and 5 connected to the gate device 1, for example.

  In the above embodiment, since the information path and the power path are separated, the power line L1 and the information line L2 are connected to the gate device 1 respectively. However, if the information signal is transmitted by the power line carrier, the power path Can also be used as the information path, so that only the power line L1 can be used for wiring, and wiring construction can be simplified. That is, the preceding wiring in each switch box 90 is only the power line L1, correspondingly, the terminal portions 31a and 31b and the information path connection port 32 of the gate device 1 are eliminated, and only the terminal portions 21a and 21b and the power path connection port 22 are provided. And The basic function module 4 is provided with a PLC modem unit 45a that is connected to the power line L1 through the connector 42a and the gate device 1 as shown in FIG. The information signal received via the PLC modem unit 45a is output to the arithmetic processing unit 47, and the information signal input from the arithmetic processing unit 47 is transmitted from the PLC modem unit 45a.

  Note that the power line carrier modulation scheme employed in the PLC modem unit 45a may be any of various schemes such as a broadband spread spectrum scheme, a multicarrier scheme, and an OFDM scheme, and is not specifically described here. In the example shown in FIG. 7, the information signal transmitted by the power line carrier communication is separated by the PLC modem unit 45a of the basic function module 4, and the information signal is transmitted between the function modules 4 and 5 via the terminal units 46b and 56b. Although transmission / reception is performed, each function module 5 may be provided with a PLC modem unit, and each function module 5 may perform transmission / reception of an information signal by power line carrier communication.

  In this embodiment, the extended function module 5 receives power supply and exchanges information signals via the basic function module 4, and secures both the power path and the information path in the extended function module 5. Depending on the function of the extended function module 5, only one of power supply and information signal transmission / reception may be performed to secure either the power path or the information path. By connecting and using, it is possible to easily cope with expansion of functions.
