【Example】

(Embodiment) First, a remote monitoring control system to which the present invention is applied will be described. FIG. 7 shows the remote monitoring control system.
As shown in the figure, a plurality of operation terminals A for monitoring the operation state of the switch SW and a plurality of control terminals B for controlling the load L are transmitted through two signal lines Ls. A control terminal B connected to the device C, creates control data based on operation data generated by operating the switch SW on the operation terminal A, and transfers the control data to the control terminal B connected to the load L.
To control the operation of the load L in accordance with the operation of the switch SW.

The operation terminal A and the control terminal B include:
A unique address is set for each, and the transmission processing device C individually recognizes the operation terminal A and the control terminal B using these addresses. The transmission processing device C transmits a transmission signal Vs having a format as shown in FIGS. 8A and 8B to the signal line Ls. The transmission signal Vs includes a start pulse ST indicating the start of signal transmission and a mode data signal M indicating a signal mode.
D, an address data signal A for transmitting address data for individually calling the operation terminal A and the control terminal B
D, a control data signal CD for transmitting control data for controlling the load L, a checksum data signal CS for detecting a transmission error, and a return signal from the operation terminal A or the control terminal B. The provided signal return period WT
Multiplexed (± 24 V) pulse width modulated signal and time-division multiplexed.

In each operation terminal A and each control terminal B, when the address data transmitted by the transmission signal Vs received via the signal line Ls matches the address data set in advance, the transmission signal Vs And return control data as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via an appropriate low impedance) in synchronization with the signal return period WT of the transmission signal Vs.

The transmission processing device C is provided with a dummy signal transmitting means and an interrupt signal processing means. The dummy signal transmitting means always sets the mode data signal MD in the dummy mode, and always transmits a dummy transmission signal provided with an empty address not set in each of the operation terminal A and the control terminal B as address data. Further, the interrupt signal processing means generates the interrupt signal in any of the operation terminals A shown in FIG.
Upon receiving the interrupt signal Vi as shown in (c), after detecting the operating terminal A that has generated the interrupt signal, the operating terminal A is accessed to return the return data.

That is, a dummy signal is normally transmitted to the signal line Ls by the dummy signal transmitting means, and the interrupt signal Vi generated from the operation terminal A in accordance with the operation of the switch SW is used as the start pulse signal ST of the dummy transmission signal. When synchronously detected, the transmission signal Vs in which the mode data signal MD is set to the address confirmation mode is transmitted from the transmission processing device C by the interrupt processing means. In the address confirmation mode, the operation terminals A having a part of the address in common are grouped, and the transmission signal Vs is collectively transmitted for each group. When receiving the transmission signal Vs in which the mode data signal MD is in the address confirmation mode, the operation terminal A that has generated the interrupt signal Vi sets the operation terminal A in synchronization with the signal return period WT of the transmission signal Vs. The returned address data is returned as reply data. In this way, the transmission processing device C specifies the address of the operation terminal A that has generated the interrupt signal Vi, and accesses the operation terminal A using the specified address, thereby connecting to the operation terminal A. Operation data corresponding to the operated state of the switch SW is received as return data.

In the transmission processing device C, based on the operation data returned from the operation terminal A, the control data to be transmitted to the control terminal B connected to the load L whose correspondence with the switch SW is set in advance. And create
The transmission signal Vs including the control data is transmitted to the signal line Ls, and the control data is transmitted to the corresponding control terminal B to control the load L. Thus, the load L corresponding to the operation of the switch SW is controlled.

Hereinafter, as shown in FIG. 1, an operation terminal A to be mounted on the surface of a wall using the mounting device of the present embodiment has a case 30 formed in a flat box shape.
Is formed in a thin structure in which a plurality of switches SW are arranged on the front surface of the device. Each signal line L is provided on the back of the case 30.
s to which the wire connector (not shown) is connected by a so-called hook sealing method.
Each of the conductive plates 18 is electrically connected to each other, and each of the conductive plates 18 is electrically connected to each of the signal lines Ls via an electric wire connector .

The mounting device for mounting the operation terminal device A on a wall surface includes a plate frame 11 embedded in the wall surface and mountable to an embedding box for a ready-made wiring device, and an operation device mounted on a front surface of the plate frame 11. In a state where the terminal device A is arranged, the terminal device A is configured with a decorative plate 12 attached to the plate frame 11. The following description is for a case where three operation terminals A are connected in series. However, the number is not limited to three as long as the number is plural.

The plate frame 11 is in the form of a rectangular frame having openings 13 corresponding to portions to which the operation terminals A are to be mounted. A mounting hole 14 formed of a long hole to be screwed at is formed. Here, for example, when the embedding box corresponds to one of the operation terminals A, the embedding box is mounted on the wall surface using the mounting hole 14 at the center, for example. At both sides of the mounting hole 14, there are also formed mounting holes 15 which can be mounted by using a clamp in an opening formed in the wall panel.

A pair of inverted L-shaped holding claw pieces 16 for temporarily holding the operation terminal A are protrudingly provided on both sides of the wall mounting portion and near the both ends. Here, the operating terminal A is formed with insertion pieces 31 protruding from both sides of both ends thereof, and the insertion pieces 31 are placed between the claw at the tip of the holding claw 16 and the front face of the plate frame 11. To temporarily hold the operation terminal device A.

A plurality of fitting holes 17 are formed in the outer peripheral portion of the plate frame 11, and fitting holes projecting from the inner surface of the decorative plate 12 into the fitting holes 17 as shown in FIG. The claw pieces 22 are fitted and fixed to the plate frame 11. That is, by attaching the decorative plate 12 to the plate frame 11 while temporarily holding the operation terminal device A, the operation terminal device A is completely fixed. The decorative plate 12 has an opening 21 for exposing the front surface where the switch SW of the operation terminal A is arranged.

The above description has been made on the mounting of the operation terminal A by the mounting device 10 of the present embodiment. However, by adopting the structure described below, it is possible to mount the operation terminal A by the above mounting procedure. The structure is such that the operation terminal A can be connected to the signal line Ls at the same time. The mounting device 10 of this embodiment includes a conductive plate 18, and a press-fit groove 19 for fixing the conductive plate 18 to the plate frame 11 is formed from the back side of the plate frame 11 as shown in FIG. Conductive plate 18
Is formed by bending two places at both ends and a center part inwardly in a U-shape. The press-fit groove 19 is formed along both edges of the plate frame 11, and the bent portion 18 a of the conductive plate 18 is formed on the inner surface of the rising piece of the holding claw piece 16 (operation terminal A).
(The surface facing the side where the insertion piece 31 is inserted). In addition, the terminal A for operation of the plate frame 11
The portion corresponding to the insertion piece 31 is recessed from other surfaces. Therefore, the conductive plate 18 is exposed on the inner surface of the holding claw piece 16.

A conductive portion connected to an internal circuit is formed on the distal end surface of the insertion piece 31 of the operation terminal A. In addition, this conductive part is directly connected to the line connected to the signal line Ls using the above-described wire connector.
Therefore, in a state where the operation terminal device A is temporarily held on each holding claw piece 16, a line connected to the signal line Ls of each operation terminal device A via the conductive plate 18 is supplied and connected. For this reason, if the signal line Ls is connected to the back side of any one of the operation terminals A by using the electric wire connector, all the operation terminals A
Are connected to the signal line Ls.

The plate frame 11 and the decorative plate 12 are made of synthetic resin. For this reason, mechanical strength may be a problem. Here, the effect of reinforcing the plate frame 11 can be obtained by press-fitting the conductive plate 18 into the press-fitting groove 19. However, if mechanical strength is a problem, the metal reinforcing plate 2 may be used.
3 may be used integrally. The reinforcing plate 23 is formed in a shape substantially coinciding with the plate frame 11 by stamping a sheet metal or the like, and has insertion holes 24 and 25 corresponding to the mounting holes 14 and 15 of the plate frame 11, respectively. It is.

The reinforcing plate 23 is used for the plate frame 11
Is mounted between the wall surface and the plate frame 11 when the is mounted on the wall surface. The plate frame 11 has a recess 29 on the back side for fitting the reinforcing plate 23. Therefore, the operation terminal A can be constructed in a state of protruding from the wall surface in the same manner as when the reinforcing plate 23 is not used. It goes without saying that the reinforcing plate 23 does not contact the conductive plate 18.

In the above description, the case where the conductive plate 18 is press-fitted into the plate frame 11 has been described, but the conductive plate 18 may be integrally formed with the plate frame 11 by insert molding in order to save the time and labor for press-fitting. Further, the reinforcing plate 11 may be formed integrally with the plate frame 11. (Embodiment 2) Another embodiment of the present invention will be described with reference to FIGS. In the case of the first embodiment, the wiring of the signal lines Ls between the operation terminals A, that is, the so-called feed wiring can be performed simultaneously with the attachment of the operation terminals A.
However, for connection with the signal line Ls, it is necessary to connect any one of the operation terminals A to the signal line Ls. Therefore, in the present embodiment, the connection of the signal line Ls is also facilitated, so that the construction for connecting a plurality of operation terminals A at one place is further facilitated.

In this embodiment, for example, when three operation terminals A are connected in series, the operation terminal A
Is formed so as to be closed from the wall surface side, and a wire connector 27 for integrally connecting the signal line Ls to the closed portion 26 is formed, and the signal connected to the wire connector 27 is formed. Each of the lines Ls is connected to the conductive plate 18 by a conductive member 20 wired through the inside of the closing portion 26. By doing so, the signal line Ls can be easily connected to the operation terminal device A using the electric wire connector 27.

[0027] As the wire connector 27, have a U-shaped portion, and a terminal plate electrically connected to the conductive member 20, and a locking spring which is accommodated in a U-shaped portion of the terminal plate 2 sets
Was paid, between the locking piece of the locking spring and the opposing surface of the terminal plate to which the locking piece facing the wire insertion holes for inserting the core part of the peeling off the coated signal line Ls is provided et Re What is called a quick connection terminal structure may be used. However, the wire connector may have any structure.
