Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Technical Field j The present invention provides a method for accessing a monitoring terminal from a base unit and returning monitoring data indicating the state of an operation switch, and for controlling the monitoring data based on the monitoring data. This relates to a remote monitoring and control device in which generated load control data is time-division multiplexed transmitted from a parent device to a control terminal device.

[1! amount! Branch t1 This type of remote monitoring and control I device that remotely controls a load such as a lighting fixture has a plurality of monitors each having a unique address and monitoring the status of the operation switches SW, ~SW ports, as shown in FIG. a plurality of control terminals 3 for which unique addresses are set and which control the loads L, -Ln corresponding to the operation switches sw1 to SWn, and each monitoring terminal 2 to access the operation switch SW1. ~Returns the operation monitoring data indicating the status of SWn, and also controls the corresponding control &
A signal #
The base unit 1 and each terminal unit 2 and 3 were connected to each other, and both data were transmitted by time division multiplexing. By the way, in such a remote monitoring and control device, it is necessary to set a unique address by making the monitoring terminal 2 and the control terminal 3 correspond to each other. This address setting switch was generally placed in a hidden position that was difficult to operate to prevent accidental recovery. Therefore, when modifying an existing system, if you want to change the unique address, you have to remove the entire appliance or the cover and operate the address setting switch, which is a small switch, making the process of changing the unique address cumbersome. There was a problem.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to facilitate the work of changing the address of a monitoring terminal and to prevent address setting errors. The object of the present invention is to provide a remote monitoring and control device that can perform the following tasks.

[Disclosure of the invention] (*Base side) Figures 1 to 4 show an embodiment of the present invention.
! In a remote monitoring and control system similar to the conventional example in which operation monitoring data and V load control data are time-division multiplexed between 1 and each terminal 2 and 3, normal monitoring and control mode and address setting are performed. Mode switch 1 to switch modes
5 and a transmission signal sending stage for accessing an appropriate control terminal 3 and sending out a transmission signal Vs in the address setting mode when the mode switch 15 is switched to the address setting mode. , the control M terminal device 3 is provided with an access display means for displaying that the access is made by setting the load and Ln to a predetermined control state when accessed by the transmission signal of the address setting mode, and the control M terminal device 3 is also provided with an access display means that is replaceable. The address setting means from the non-volatile memory 21 determines its own address based on the address data of the signal when the operation switches SW1 to SWn are operated while the transmission signal Vs of the address setting mode is being received. The monitoring terminal device 2 is provided with an address to be written into the non-volatile memory;

Here, the parent 8!1 has the reply detection section 10 and the judgment processing section 1.
1, an address generation section 12, a control data generation section 13, a signal transmission section 14, and a mode switch 15. In the judgment processing section 11, the mode switch 15
Check whether it is set to normal monitoring control mode or address setting mode, and
In the case of the normal supervisory control mode, the load to be controlled is determined based on the supervisory data received via the return detector 10, and the supervisory terminal 3 connected to -Ln is accessed. A normal transmission number M VS for transmitting load control data is sent out to the signal line 4 from a signal transmission section consisting of an address generation section 12, a control data generation section 13, and a signal transmission section 13. As shown in Figure (a) of @S, this transmission signal S is formed of a start signal ST, an address data signal AD, and a load control data signal CD, and sends out the load control data signal CD. The period from the start to the dog start synchronization signal ST is set as the return waiting period W during which the return signal VL) can be received. In the example, 1:1
Since the unique addresses of the corresponding monitoring terminal 2 and V control terminal 3 are set to be the same, the base unit 1 accesses both terminals 2 and 3 simultaneously using the transmission signal Vs. The fabricated monitoring data is returned from the monitoring terminal 2 during the return waiting period W, and new load control data is created to be transmitted to the corresponding control terminal 3, and the new load control data is handled in a large access cycle. The information is transmitted to the control terminal 3 to control the loads L1 to L1.

On the other hand, when the mode switch 15 is set to the address setting mode side, the determination processing unit 11 controls the transmission signal Vs of the address setting mode, which transmits data indicating the address setting mode instead of the load control data. If a reply M is received from any of the monitoring terminals 2 during the return waiting period W of the transmission signal Vs in this address setting mode, the next A transmission signal Vs in an address setting mode for accessing the control terminal 3 is sent out, and the same operation is repeated. Note that the transmission signal sending means for sending out the transmission signal Vs in the address setting mode is formed by the determination processing section 11 and I/the signal transmission section.

Furthermore, the monitoring terminal 2 includes a signal receiving section 20, a nonvolatile memory 21, a judgment processing section 22, and a return (ffat number sending section 23). When the normal transmission signal Vs is received by the terminal, the address data transmitted by the transmission signal Vs is matched with the own unique address set in the address setting means consisting of the non-volatile memory 21. When an address match is obtained, the return M signal sending unit 23 switches the operation switch SWn during the return waiting period W of the transmission signal Vs.
This shows the operating state of: The lA signal vb is sent out. On the other hand, the transmission signal Vs in address setting mode
is received, it is checked whether or not the capture switch SWn is operated, and when the operation switch SWn is operated, the address data transmitted in the transmission signal VS is transmitted to the self. It writes the unique address into the non-volatile memory 21, which is an address setting means, and waits for a reply signal vb to be sent back with monitoring data indicating that the operation switch SWn has been operated. It is designed to be sent to W between 511w1 and 511w1. Note that the nonvolatile memory 21 is EEP R
It is formed by an OM or a RAM equipped with a backup battery, and the address writing means is formed by the judgment processing section 22.

The control terminal 3 also includes a signal receiving section 30, an address setting section 31, a judgment processing section 32, and a load control relay Ry.
and a relay output section 33 consisting of a drive transistor Q. In the judgment processing section 32, when the signal receiving section 30 receives the normal transmission signal Vs, the address data and the own unique A match with the address is determined, and when an address match is obtained, the load control data transmitted following the address data is taken in and the load control relay RY is driven to control the load Ln on and off. ing. On the other hand, when the transmission signal Vs in the address setting mode is received, it is determined whether the address matches, and if the address match is obtained, the load control relay R) turns on and off the load Ln at regular intervals. Access is displayed by driving 1. In the embodiment, the access display means is formed by the judgment processing section 32, the relay output section 33, and the load -Ln.
An access indicator lamp or the like may be provided separately. It goes without saying that the base unit 1 may transmit the address setting mode transmission signal S for turning on and off the load Ln at regular time intervals.

The operation of the embodiment will be specifically explained below.

If the mode switch 15 of the main unit 1 is currently turned off and set to the normal monitoring control mode, the main unit R1
A transmission signal Vs as shown in FIG. 5(a) is transmitted, which sequentially cyclically accesses each terminal device 2 and 3 from the monitoring terminal device 2 with which an address match has been obtained! @Figure 5 (b
), the operation switches sw, , sw, . . . , SWw, SWn,
Monitoring data indicating the operating status of SW, . . . is sent back as a reply signal vb. Parent Wi
1, new load control data was created to control the corresponding load, ~Ln, based on the returned operation monitoring data, and the same unique address as each monitoring terminal 2 was set in the next access cycle. New load control data is transmitted to the control terminal 3, and the loads L1 to Ln are controlled according to the operating states of the corresponding operation switches SW1 to SWn. In addition, at this time, the monitoring terminal 2 that is being accessed at the same time
Monitoring data indicating the operating states of the operating switches SW1 to SWn is sent back to the base unit 1, and similar monitoring and control operations are repeatedly performed.

On the other hand, when the mode switch 15 is turned on and set to the address setting mode, first, the control terminal 3 whose unique address is "1" is accessed from the base unit 1 as shown in FIG. 6(a). A transmission signal Vs as shown is repeatedly sent out. In the control terminal device 3 whose unique address is "1", by receiving this transmission signal Vs and transmitting the transmitted data indicating the address setting mode, the +q disconnection processing circuit 32 operates in the address setting mode, The relay output section 3 is configured to turn on and off the load L1 at regular intervals of one hour.
Control 3. In addition, the judgment processing unit 2 of each monitoring terminal 2
2 enters the address setting standby state by receiving the transmission signal VS in the address setting mode, and enters the address setting standby state as shown in FIG.
As shown in b), it should correspond to the load L1 that is accessed! 1 operation switch SW, 1 is written as a unique address in the non-volatile memory 21 of the monitoring terminal 2 that monitors the operation switch SW3, and as shown in FIG. 6(e), the operation switch SW,
A reply signal vb indicating that has been repeated is sent back to base unit 1. Upon receiving this return signal vb, base unit 1 assumes that the address setting for the transmission signal Vs that is currently being sent has been completed, and the address setting for the transmission signal Vs that is currently being sent is completed. The transmission signal Vs for accessing the next control terminal 3 whose unique address is set to "2" is transmitted in the address setting mode.

The control terminal 3 accessed by this transmission signal Vs displays access by turning on and off the connected load at regular time intervals, as in the case described above. In this state, as shown in FIG. 6(c), when the operation switch SW2 that should correspond to the load L2 is operated, the nonvolatile memory 2 of the monitoring terminal 2 that monitors the operation switch SW2
"2" is entered into 8 as a unique address, and a reply signal vb indicating the address setting is sent back to the parent 8!1. Similarly, the control terminal 3 with the unique address "3" is set.
If the operation switch SWn is operated (as shown in FIG. 6 (cl)) while the terminal is being accessed, the unique address of the monitoring terminal 2 is changed so that the load is controlled by the operation switch SWn. is set.

As described above, the load L, ~L, which is accessed and displayed by switching the IAI mode switch 15 to the access setting mode side and turning it on and off at fixed time intervals.
nl: Just by operating the corresponding operation switch SW, -SWn, the corresponding operation switch SW, -SW
The address of the monitoring terminal 2 that monitors n can be set so that 1=1N corresponds to the address of the control terminal 2 that loads and controls 1 to Ln corresponding to the operation switches SW, ~SWn. It has become. Therefore, unlike the conventional example, there is no need to operate a small address setting switch that is difficult to operate.
You can easily change the address of , and you can set the address while actually checking the correspondence between the operation switch, 2ch s'vv, ~SWn, and the load, ~Ln. It is important to prevent mistakes.

[Effect of the Invention 1] As described above, the present invention allows the base unit to access the monitoring terminal and return the monitoring data indicating the state of the operation switch, and also transmits the load control data formed based on the monitoring data to the base unit. In a remote monitoring and control VC system that accesses a control terminal from a PC and performs time-division multiplex transmission, there is a mode switch that switches between normal monitoring and control mode and address setting mode, and the mode switch is switched to address setting mode. The base unit is equipped with an address setting mode I' signal sending means for accessing an appropriate control terminal and sending out an address setting mode transmission signal, and when accessed by the address setting mode transmission signal, the load is The control terminal is provided with access display means for displaying that the control terminal is in a predetermined control state and has been accessed, and an address setting means consisting of a rewritable non-volatile memory and a transmission signal of the address setting mode is received. The monitoring terminal is equipped with an address writing means that determines its own address based on the address data of the signal and writes it to the nonvolatile memory when the operation switch is operated in the state, and the mode switch is set to access. Simply operate the production switch that should correspond to the load that is being accessed while switching to the mode, and the address of the monitoring terminal that monitors that production switch can be used to control the load that corresponds to the production switch. Control terminal address and 1:
