2. Description of the Related Art Conventionally, a remote monitoring control system has been considered in which a plurality of operation terminals and control terminals are connected to a transmission processing device through a two-wire signal line in a time division multiple connection system. ing. Addresses are set separately for the operation terminal and the control terminal, and the transmission processing device individually recognizes each operation terminal and each control terminal by the address. The operation terminal includes a switch and transmits an interrupt signal generated by operating the switch to the transmission processing device. When the transmission processing device receives the interrupt signal, it searches for the operation terminal device requesting the interrupt,
Further, the control data is transmitted to the control terminal device whose correspondence is preset by the retrieved operation terminal device and address. The control terminal device that has received the control data controls the connected load in accordance with the operation of the switch.

More specifically, the remote monitoring and control system has a structure shown in FIG. 18, for example. To the transmission processing device 81, a plurality of operation terminals 82 for monitoring the operation state of the switch SW and a plurality of control terminals 83 for controlling the load L are connected via a two-wire signal line Ls. It Individual addresses are set in the operation terminal 82 and the control terminal 83, and the transmission processing device 81 uses the addresses to operate the operation terminal 82 and the control terminal 83.
Recognize individually.

The transmission processing device 81 is connected to the signal line Ls by
A transmission signal V having a format as shown in FIGS.
send s. That is, the transmission signal Vs includes the start pulse ST indicating the start of signal transmission, the mode data signal MD indicating the signal mode, the operation terminal 82 and the control terminal 83.
Address data signal AD for transmitting address data for individually calling, control data signal CD for transmitting control data for controlling load L, checksum data signal CS for detecting a transmission error, operation terminal device 82, A bipolar (± 24) including a signal return period WT which is a time slot for receiving a return data signal from the control terminal 83.
V) is a time division multiplexed signal, and data is transmitted by pulse width modulation.

In each operation terminal 82 and each control terminal 83, when the address data transmitted by the transmission signal Vs received through the signal line Ls matches the preset address data, the transmission signal Vs The control data is fetched from the device and the return data is synchronized with the signal return period WT of the transmission signal Vs as the current mode signal (a signal sent by short-circuiting the signal lines Ls via an appropriate low impedance). Send it back.

Further, the transmission processing device 81 is provided with dummy signal transmitting means and interrupt signal processing means. The dummy signal transmitting means always sends out a dummy transmission signal in which the mode data signal MD is in the dummy mode. Further, the interrupt signal processing means receives the interrupt signal V when any one of the operation terminals 82 receives an interrupt signal Vi as shown in FIG.
The operation terminal 82 that generated i is searched, and the address data set in the operation terminal 82 is returned as reply data. That is, the dummy signal transmitting means always sends the dummy transmission signal to the signal line Ls, and the interrupt signal Vi generated from the operation terminal 82 in accordance with the operation of the switch SW is synchronized with the start pulse signal ST of the dummy transmission signal. Then, the transmission processing device 81 sends out the transmission signal Vs in which the mode data signal MD is in the address confirmation mode by the interrupt processing means to the signal line Ls. In each of the operation terminals 82, an interrupt flag for requesting an interrupt when an interrupt signal Vi is generated is set, and the operation terminal 82 to which the interrupt flag is set is set.
Then, when the mode data signal MD receives the transmission signal Vs in the address confirmation mode, the address data set in the operation terminal 82 is returned as reply data in synchronization with the signal return period WT of the transmission signal Vs. In this way, the transmission processing device 81 can acquire the address of the operation terminal device 82 that generated the interrupt signal Vi.

In the transmission processing device 81, the interrupt signal Vi
When the address of the operation terminal 82 that has generated
The control data to be transmitted to the control terminal 83 to which the load L having the preset correspondence relationship with the switch SW is connected is generated, and the transmission signal Vs including the control data is transmitted to the signal line Ls to perform the corresponding control. The control data is transmitted to the mobile terminal 83 to control the load L.

In the operation terminal 82 and the control terminal 83, the transmission signal Vs transmitted through the signal line Ls, respectively.
By rectifying and stabilizing the full-wave, the power supply for the operation of the internal circuit is obtained. A power source is separately provided for the load L connected to the control terminal 83. By the way, as the operation terminal device 82 used in this type of remote monitoring and control system, the present inventors have previously proposed to use a case in which the rear surface is mounted in front of the construction surface (Japanese Patent Application No. 4- 288285). On the other hand, the switches SW provided for one mounting frame usually differ depending on the usage conditions. To cope with such a difference in the number of switches SW, one switch SW is provided in one case.
It is the current situation that each of the four operation terminal devices 82 is provided to be prepared.

[0009]

However, in the above configuration, it is necessary to use a case in which the number of switches SW is different according to the use conditions, and there is a problem that the number of product types increases. The present invention is intended to solve the above problems, and by adopting a case in which up to three pieces can be attached to one attachment frame, the number of cases attached to the attachment frame for the same product can be changed. It is intended to provide a terminal for operating a remote monitoring and control system in which the number of switches can be changed only by itself.

[0010]

According to a first aspect of the present invention, a plurality of terminals each having an address are connected to a transmission processing device by a time division multiplex connection method via a two-wire type signal line for transmission. The processing device individually accesses the terminals by sending a transmission signal including address data to the signal line, and when the operation data from the terminal is received during the signal return period set in synchronization with the transmission signal, the processing data is changed to the operation data. The control data is generated based on the control data, and the control data is transmitted to another terminal device in which the correspondence between the terminal device that generated the operation data and the address is preset to control the load connected to the terminal device. Used in a remote monitoring and control system, equipped with a case that is attached to a mounting frame that is fixed to the construction surface and whose rear surface is located in front of the construction surface, and is equipped with a switch that generates operation data. In a terminal device, a case is formed to a size that allows up to three attachment frames to have a size substantially the same as the attachment frame for three large polygons standardized for embedded wiring equipment. It is characterized by

When the operation data from the terminal is received during the signal return period set in synchronization with the transmission signal, the control data is generated based on the operation data. However, it is used in a remote monitoring and control system that controls the load connected to the terminal device that generated the operation data by transmitting control data to another terminal device that has a preset correspondence with the address. In an operation terminal equipped with a case that is attached to a mounting frame that is fixed to the construction surface and whose rear surface is located in front of the construction surface and that has a switch for generating operation data. The operation handle of the switch has a rectangular shape projected on the front surface of the case, and one side edge is pivotally attached to the case so as to be swingable in the front-back direction with respect to the front surface of the case. The switch is operated by.

Since the contact pieces that are exposed to each other are provided, and the contact pieces of adjacent cases contact each other in a state where a plurality of cases are attached to the attachment frame, up to three pieces can be attached corresponding to one attachment window. When the cases are used, the signal lines can be sent and wired between the cases only by mounting the plurality of cases on the mounting frame.
That is, if the signal line is directly connected to only one case attached to the mounting frame, it is not necessary to connect the signal line to the other cases.

According to the structure of the invention of claim 5, the terminal portion is exposed on the rear surface of the case, and the connector connected to the signal line is detachably coupled to the terminal portion. Therefore, the connector is provided on the rear surface side of the case. All you have to do is to secure enough space to place the. Further, by adopting the configuration of claim 5 in combination with the configurations of claim 3 and claim 4, it becomes possible to connect the signal line to a plurality of cases only by connecting the connector to one case. Therefore, it suffices to secure a space for providing one connector on the rear surface side of the case regardless of the number of cases used.

A plate 7 is provided. Further, an insulating base 8 which is a synthetic resin molded product is simultaneously formed integrally with the conductive plate 7. One end of the conductive plate 7 serves as the first connecting portion 7a mounted on the insulating base 8, and the other end thereof projects from the insulating base 8 and is inserted and connected to the second terminal portion 3b. It is the connecting portion 7b.

Two cases 1 using the above-mentioned conductive plate 7
When electrically connecting the signal transmission plate 3 between the two, the second connecting portion 7b of the conductive plate 7 is inserted into the second terminal portion 3b of the signal transmission plate 3 of the case 1, and the insulating base 8 Is placed on the front side of the central piece 67 between the adjacent mounting windows 61, the first terminal portion 3a of the signal transmission plate 3 of the other case 1 is elastically contacted from the front. As described above, the signal transmission plates 3 of both cases 1 are electrically connected via the conductive plate 7.
That is, since the signal transmission plate 3 is electrically connected to the signal line Ls via the connector 50, the transmission signal can be transmitted between both cases 1. With this configuration,
When the connector 50 is connected to one of the two cases 1 and the signal line Ls is connected to the one case 1, the other case 1 is connected via the signal transmission plate 3 and the conductive plate 7. Since the signal line Ls will be electrically connected,
Even if the case 1 is provided in each of the two mounting windows 61, only one connector 50 needs to be provided.

Up to three cases 1 can be attached to one attachment window 61. Therefore, when a plurality of cases 1 are attached to one attachment window 61, they are provided in adjacent cases 1. The contact pieces 9 contact each other. The contact piece 9 is connected to the signal line L via the connector 50 like the signal transmission plate 3.
Since it is electrically connected to s, the transmission signal is transmitted between the two cases 1 through the contact piece 9 in the same manner as when transmitting the transmission signal between the cases 1 corresponding to the two mounting windows 61. It can be transmitted. That is, also in this case, if the connector 50 is connected to one of the plurality of cases 1, the signal line L for all the cases 1 is connected.
It will be electrically connected to s. In short, if the case 1 is attached to one attachment frame 60, the signal line L can be obtained by using only one connector 50 regardless of the number of cases.
It is possible to make an electrical connection with s.

According to the invention of claim 1, up to three mounting frames can be attached to the mounting frame having substantially the same size as the mounting frame for three large squares standardized for the embedded wiring device. Since the case is formed in the dimensions, the number of the switches provided at one location can be adjusted by increasing or decreasing the number of cases attached to the mounting frame. That is, it is possible to increase or decrease the number of switches at one location in one type of product according to the usage conditions, and it is possible to reduce the number of product types.

According to a second aspect of the invention, the operating handle of the switch has a rectangular shape projected on the front surface of the case, and one side edge of the case is swingable in the front-back direction with respect to the front surface of the case. Since the switch is operated by pressing the operation handle, the distance from the operation handle pivot position to the switch operation position can be made relatively large even if the case is small. On the other hand, there is an advantage that the stroke of the pushing operation can be made larger than that of the operation handle of the type that moves straight back and forth. Further, even if the case is small, the operation handle can be formed in a relatively large size, so that there is an advantage that it can be assembled easily while allowing smooth movement.

According to a third aspect of the present invention, when a terminal frame is provided on both side surfaces of the case and a mounting frame having a plurality of mounting windows is used, the connecting member is arranged between the mounting windows of the mounting frame. Since the terminal portions can be connected to each other via the connector, if the signal line is connected to the case arranged in one mounting window of the mounting frame, the case and the connecting member can be connected to the other cases. By simply attaching to the mounting frame, the signal line can be sequentially sent and wired through the connecting member.
This has the effect of eliminating the work of connecting signal lines.

According to a fourth aspect of the present invention, when a plurality of cases are electrically connected to the signal line and a plurality of cases are attached to one attachment window of the attachment frame, a pair of exposed contacts are provided on both circumferential surfaces of the opposite cases. Since the contact pieces of adjacent cases contact each other in a state in which a plurality of cases are mounted on the mounting frame, the case that can be mounted up to three corresponding to one mounting window is used. In this case, the signal line can be sent between the cases by simply mounting a plurality of cases on the mounting frame. That is, if the signal line is directly connected to only one case attached to the attachment frame, the effect that there is no need to connect the signal line to the other cases is obtained.

According to the invention of claim 5, the terminal portion is exposed on the rear surface of the case, and the connector connected to the signal line is detachably coupled to the terminal portion. Therefore, the connector can be arranged on the rear surface side of the case. All you have to do is secure a space.
Further, by adopting the configuration of claim 5 in combination with the configurations of claim 3 and claim 4, it becomes possible to connect the signal line to a plurality of cases only by connecting the connector to one case. Therefore, it suffices to secure a space for providing one connector on the rear surface side of the case regardless of the number of cases used.

According to the sixth aspect of the present invention, the decorative plate is attached to the front surface of the mounting frame, and the front surface of the case is set rearward of the front surface of the decorative plate. The case can be placed within the dimension up to the front surface of the plate, and there is an effect that the case can be installed with a beautiful appearance.
