(Embodiment 1) An embodiment of the present invention will be described with reference to FIGS.
In this embodiment, a master unit A, a plurality of monitoring terminals B for monitoring the operation state of the switch S, and a plurality of control terminals C for controlling the operation of the load Z are connected to a signal line L in a bus form. When the master unit A stores a load control table indicating the correspondence between the monitoring terminal B and the control terminal C, and receives monitoring data according to the operation state of the switch S from the monitoring terminal B, In a remote monitoring and control system for transmitting control data for controlling the operation of the load Z to a control terminal C corresponding to the monitoring terminal B in accordance with the load control table, a unique address set for itself when connected to the signal line L A connection information transmitting means (not shown) for transmitting the connection information including the connection information to the base unit A is provided in each of the terminals B and C, and as shown in FIG. 1, the terminals B and C are connected based on the connection information. Connection detection means 10 for detecting Each terminal unit B, is characterized in that is provided with a load control table setting unit 11 for setting a load control table according to the preset fixed rule based on the connection order of the C signal processing unit 1 of the master unit A. The load control table is stored in the storage unit 2 of the master unit A.

Hereinafter, a method of setting the load control table according to the present embodiment will be described with a specific example. Fig. 2 shows the master unit A
2 shows a case where two monitoring terminals B and two control terminals C are connected via a signal line L. Here, it is assumed that the unique addresses of the monitoring terminal B are 01 and 05, and the unique addresses of the control terminal C are 20 and 26. The order in which the terminals B and C are installed is indicated by a circled number on the left side of each of the terminals B and C.

First, the monitoring terminal B (address = 01)
To the signal line L. At this time, the monitoring terminal B transmits to the master A a connection information determined in advance together with its own unique address. Master A detects the connection state of monitoring terminal B from the connection information. Then, when the connection of the monitoring terminal B is detected in this way, the unique address (01) of the monitoring terminal B is written in the item of the monitoring terminal in the load control table.

Next, the control terminal C (address = 20) is connected to the signal line L. At this time, the control terminal C transmits the connection information together with its own unique address to the base unit A, similarly to the monitoring terminal B. Master A detects the connection state of control terminal C from the connection information, and writes the unique address (20) of control terminal C in the control terminal section of the load control table.

Thereafter, if the monitoring terminal B (address = 05) and the control terminal C (address = 26) are connected in this order,
The load control table of the master unit A is set as shown in FIG. That is, in the case of this specific example, the case is shown where the monitoring terminal B and the control terminal C correspond one-to-one, and the monitoring terminal B and the corresponding control terminal C correspond to each other.
In this order, a load control table is automatically created.

FIG. 3 shows a monitoring terminal B and a plurality of control terminals C.
Shows a case in which FIG. 3 shows a case where two monitoring terminals B and four control terminals C are connected to a master A via a signal line L. Here, it is assumed that the unique addresses of the monitoring terminal B are 01 and 05, and the unique addresses of the control terminal C are 20, 22, 25, and 26. Then, as in the case of FIG.
Are indicated by numbers in circles on the left side of the terminals B and C, respectively. In this specific example, when the switch S of the monitoring terminal B (address = 01) is operated, the built-in relays of the three control terminals B (address = 20, 22, 25) are driven. The operation of the load Z is controlled. The monitoring terminal B (address = 5) and the control terminal C (address = 26) have a one-to-one correspondence.

In this case, first, the monitoring terminal B (address = 01) is connected to the signal line L. At this time, the monitoring terminal B transmits the connection information together with its own unique address to the master A in the same manner as described above. At this time, master unit A
Then, the unique address (01) of the monitoring terminal B is written in the item of the monitoring terminal in the load control table. Next, the control terminal C (address = 20) is connected to the signal line L. At this time, the control terminal C transmits connection information together with its own unique address to the master A in the same manner as described above, and the master A controls the unique address (20) of the control terminal C for load control. Write to the controlling terminal section of the table.

In this case, the control terminal C
(Address = 22) is connected to the signal line L. Also in this case, the control terminal C transmits the connection information together with its own unique address to the master A in the same manner as described above, and the master A loads the unique address (22) of the control terminal C. Write it in the item of the control terminal corresponding to the monitoring terminal B (address = 01) in the control table.

Further, the control terminal C (address = 25)
Is connected, the control terminal C (address = 20, 22)
Similarly to the above, the unique address (25) of the control terminal C is written in the item of the control terminal corresponding to the monitoring terminal B (address = 01) in the load control table. Next, the monitoring terminal B (address = 05) is connected to the signal line L. At this time, since the master A can distinguish the monitoring terminal B and the control terminal C from the unique addresses, the control terminal to the control terminal item corresponding to the monitoring terminal B (address = 01) is set. The setting of the container C is completed. For example, if the rules are determined in advance so that the unique address of the monitoring terminal B is set to 01 to 19 and the unique address of the control terminal C is set to 20 or later, the master A can monitor from the unique address. The terminal B and the control terminal C can be determined.

Thereafter, the load control table is set for the monitoring terminal B (address = 05) and the control terminal C (address = 26) in the same manner as described with reference to FIG. As is apparent from the above description, in the case of this specific example, a so-called pattern setting that enables the operation control of a plurality of desired loads Z with one switch S can be performed.

In FIG. 4, when a plurality of monitoring terminals B correspond to the same control terminal C, that is, each of the switches S of the monitoring terminal B (address = 01, 05) controls the control terminal C.
FIG. 2 shows a case where operation control is realized as a so-called three-way switch circuit in which drive control of a load Z (address = 20, 22, 25) can be performed. And the description method of FIG.
The control terminal C corresponding to the plurality of monitoring terminals B is 1
It may be an individual.

In the case of this specific example, first, the monitoring terminal B (address = 01) is connected to the signal line L. At this time, the monitoring terminal B transmits the connection information together with its own unique address to the master A in the same manner as described above. At this time, the master A writes the unique address (01) of the monitoring terminal B in the monitoring terminal field of the load control table. Next, the monitoring terminal B (address = 05) is connected to the signal line L
Connect to At this time, the monitoring terminal B is assigned the unique address (05) of the monitoring terminal B in the same manner as described above.
Is written in the monitoring terminal section of the load control table. If there are a plurality of monitoring terminals B, the monitoring terminals B
Each time is connected, the term of the monitoring terminal in the load control table is rewritten.

Then, the control terminal C (address = 20)
Is connected, the control terminal C transmits connection information to the master A together with its own unique address in the same manner as described above. In this case, in the case of this specific example, the parent machine A sets the unique address (20) of the control terminal C to the control terminal corresponding to each of the monitoring terminals B (address = 01, 05) in the load control table. Write in the term.

Hereinafter, similarly, the control terminal C (address = 2)
2 and 25), the unique addresses (22 and 25) of these control terminals C are added to the control terminal section corresponding to each of the monitoring terminals B (address = 01, 05) in the load control table. Written. Although not shown in this example, when another monitoring terminal B is connected, the monitoring terminal B (address = 0) is obtained from its unique address.
The setting of the load control table corresponding to (1, 05) is completed.

By the way, the above description has been made by dividing the case, but the monitoring terminal B described with reference to FIGS.
The load control table can be set even when the correspondence between the control terminal C and the control terminal C is mixed. That is, when the control terminal C is connected next to the monitoring terminal B, the setting based on FIG. 2 or FIG. 3 is performed, and when the monitoring terminal B is connected continuously, the setting based on FIG. A setting rule may be programmed in advance in master device A so that setting is performed. Also,
It goes without saying that the signal transmission method between the parent device A and each terminal device B is performed according to the signal transmission method during normal operation.

Embodiment 2 FIGS. 5 to 9 show another embodiment of the present invention. Although the remote monitoring control system in the first embodiment includes the master unit A, as shown in FIG. 5, signals are sent between the monitoring terminal B and the control terminal C without passing through the master unit A. In some, signal transmission is performed via a line L, and a monitoring terminal B directly supplies control data to a control terminal C. In this case, the monitoring terminal B has a control terminal table indicating a correspondence relationship with the control terminal C corresponding to the monitoring terminal B, and according to this control terminal table, the monitoring terminal B transmits control data to the corresponding control terminal C. Then, the operation of the load Z is controlled by the control terminal C.

Therefore, in this embodiment, connection information transmitting means for transmitting connection information when connected to a signal line is provided in each of the terminals B and C, and as shown in FIG. , C detecting that the connection has been made
0 and a control terminal table setting means 31 for setting a control terminal table according to a predetermined rule based on the connection order of the control terminals B and C are provided in the signal processing unit 3 of the monitoring terminal B. It should be noted that the control terminal C transmits connection information including a unique address set to itself when connected to the signal line. The control terminal table is stored in the storage unit 4.

First, a case in which one monitoring terminal B provides control data to one control terminal C in a one-to-one correspondence will be described. In this case, as shown in FIG. 7, first, the monitoring terminal B (address = 01) is connected to the signal line L. In this case, the monitoring terminal B waits for the next connection of the control terminal C. Next, the control terminal C (address = 20) is connected. This control terminal device C outputs predetermined connection information along with its own unique address to the signal line L in the same manner as described in the first embodiment. In this case, the monitoring terminal B
Since only (address = 01) is connected, the signal is received by the monitoring terminal B, and it is detected from the connection information that the control terminal C is connected. When the connection of the control terminal C is detected in this way,
The unique address (20) of the control terminal C is written in the control terminal table.

Then, in the case of this specific example, the monitoring terminal B (address = 05) is connected next. At this time, only the connection information is output from the monitoring terminal B to the signal line L.
From the signal including the connection information without the unique address, the monitoring terminal B (address = 01) determines that the connection of the control terminal C corresponding to itself has been completed, and the signal transmitted via the signal line L thereafter. Will not be accepted.

Thereafter, the control terminal C (address = 26)
Is connected, the control terminal C outputs connection information to the signal line L together with its own unique address. In this case, only the monitoring terminal B (address = 05) is in a state of receiving the signal. Therefore, when the connection of the control terminal C is detected, the monitoring terminal B (address = 05) switches to the control terminal table. The unique address (26) of the control terminal C is written into the control terminal C.

In this way, the control terminal table can be automatically set in the same manner as in the specific example described in FIG. 2 of the first embodiment. In the above case, the monitoring terminal B (address = 05) did not transmit the unique address. However, as described in the first embodiment, the preset unique address is set according to the types of the terminals B and C. If so, the unique address may be transmitted. The monitoring terminal B (address = 01) connected first did not output any signal. However, when the monitoring terminal B was connected, any terminal B, Since C is not connected, if it is set to end before the other terminals B and C are constructed, this monitoring terminal B
(Address = 01) may also be transmitted together with the connection information or the connection information and the unique address.

FIG. 8 corresponds to the specific example described in FIG. 3 of the first embodiment, and shows a case where one monitoring terminal B and a plurality of control terminals C correspond. In this case, the monitoring terminal B
After the connection, the control terminal C (address = 20, 22, 2)
5), the respective unique addresses (20, 2)
2, 25) is written in the control terminal table of the monitoring terminal B.

Then, the monitoring terminal B (address = 05)
Is connected, the monitoring terminal B (address = 01)
The setting of the control terminal table is ended. Thereafter, when the control terminal C (address = 26) is connected, the unique address (26) of the control terminal C is written in the control terminal table. FIG. 9 corresponds to the specific example described in FIG. 4 of the first embodiment, and first, the monitoring terminal B (address = 01,
05) to the signal line L in order, and then the control terminal C
(Address = 20, 22, 25) are sequentially connected. Here, in the case of the specific example described with reference to FIGS. 7 and 8, when another monitoring terminal is connected after the monitoring terminal B, the monitoring terminal B connected earlier at that time accepts a signal. However, as shown in this specific example, the program is set to accept a signal when the monitoring terminal B is continuously connected, as shown in this specific example. Therefore, each time the control terminal C is connected, the unique address (20, 22, 25) of each control terminal C is stored in the control terminal table of each monitoring terminal B.
Is connected.

In this embodiment, cases are described by dividing the cases. However, even when the correspondence between the monitoring terminal B and the control terminal C described in FIGS. It goes without saying that the control terminal table can be set.
Also, the monitoring terminal B and the control terminal C in the above description
Is transmitted according to the signal transmission method during normal operation .
