[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring and control system capable of controlling a plurality of loads by one operation.

[0002]

2. Description of the Related Art Conventionally, a remote monitoring system shown in FIG.
A control system is provided. This remote monitoring and control system
In the system, a two-wire signal line connected to the transmission control device 30
A plurality of operation terminals 31 and control terminals 3 in Ls
2 is a branch connection (multi-drop connection). Each operation
The operation terminal device 31 and each control terminal device 32 have individual
Different addresses are set, and the transmission control device 30
Using the address, the operation terminal 31 and the control terminal 32
Are individually recognized. The operation terminal 31 is a switch S ₀Be prepared
The load L is connected to the control terminal 32. In addition,
The operation terminal 31 has an output for confirming the operation state of the load L.
A confirmation light (not shown) consisting of a photodiode is provided
I have.

[0003] The transmission control device 30 controls the signal line Ls
The transmission signal Vs of the format shown in FIG. That is, a synchronization signal SY indicating the start of signal transmission, mode data MD indicating the mode of the transmission signal Vs, address data AD for individually calling the operation terminal device 31 and the control terminal device 32, control data CD for controlling the load L, Checksum data CS for detecting a transmission error, a return signal (monitoring data) from the operation terminal 31 or the control terminal 32
Is a bipolar (± 24 V) time-division multiplexed signal consisting of a signal return period WT, which is a time slot for receiving data, and data is transmitted by pulse width modulation (FIG. 7B). In each of the operation terminals 31 and the control terminals 32, when the address data AD transmitted by the transmission signal Vs received via the signal line Ls matches the preset address, the control data CD is transmitted from the transmission signal Vs. At the same time, the monitoring data is transferred to the current mode signal (signal line Ls) during the signal return period WT of the transmission signal Vs.
As a signal transmitted by short-circuiting through a suitable low impedance).

A desired operation terminal 3 is transmitted from the transmission control device 30.
When transmitting data to the control terminal 32 or the control terminal 32, a transmission signal Vs with the mode data MD as the control mode and the address of the operation terminal 31 or the control terminal 32 as address data AD is transmitted. Vs to the signal line Ls
, The operation terminal device 31 or the control terminal device 32 that matches the address data AD receives the control data CD and returns the monitoring data during the signal return period WT. The transmission control device 30 confirms that the control data CD has been transmitted to the desired operation terminal 31 or control terminal 32 based on the relationship between the transmitted control data CD and the monitoring data received during the signal return period WT. The control terminal 32 outputs a load control signal for controlling the load L according to the received control data CD, and the operation terminal 31 outputs a monitoring signal for displaying an operation confirmation of the load L according to the received control data CD. I do.

On the other hand, the transmission control device 30 normally transmits the transmission signal Vs in which the mode data MD is in the dummy mode at a constant time interval.
When trying to transmit some information to 0,
An interrupt signal as shown in FIG. 7C is generated in synchronization with the synchronization signal SY of the transmission signal Vs in the dummy mode. At this time, the operation terminal 31 sets an interrupt flag to prepare for the subsequent information exchange with the transmission control device 30. Transmission control device 30
When the interrupt signal is received, the transmission signal is transmitted while the mode data MD is set to the interrupt polling mode and the upper half bits of the address data AD (the upper 4 bits when the address data AD is 8 bits) are sequentially increased. And
In the operation terminal device 31 that has generated the interrupt signal, the upper 4 bits of the address data AD of the transmission signal in the interrupt polling mode are the upper 4 bits of the address set in the operation terminal device 31.
When the bits match, the lower half bits of the address are returned to the transmission control device 30 during the signal return period WT.
As described above, since the transmission control device 30 collectively searches for the 16 operation terminals 31 that have generated the interrupt signal, the transmission control device 30 can find the operation terminals 31 in a relatively short time.

When the transmission control device 30 obtains the address of the operation terminal 31 that has generated the interrupt signal, the mode data M
D is set to the monitoring mode, and a transmission signal having the acquired address data AD is transmitted to the signal line Ls. In response to this transmission signal, the operation terminal device 31 returns information to be transmitted to the signal return period WT. It is. Finally, the transmission control device 30 sends a signal instructing an interrupt reset to the operation terminal device 31 that has generated the interrupt signal, and releases the interrupt flag of the operation terminal device 31. As described above, information transmission from the operation terminal device 31 to the transmission control device 30 is performed by four signal transmissions from the transmission control device 30 to the operation terminal device 31 (dummy mode, interrupt polling mode, monitoring mode,
(Interrupt reset). When the transmission control device 30 wants to know the desired operating state of the control terminal 32, it is only necessary to transmit a transmission signal using the mode data MD as monitoring data.

The above operation will be briefly summarized. First, when input data by a switch is generated in the operation terminal 31, monitoring data corresponding to the input data is returned to the transmission control device 30, and when the transmission control device 30 transmits the control data CD to the control terminal 32, The control terminal 32 outputs a load control signal to control the load L. Here, the load monitoring input is given to the control terminal 32, the monitoring data corresponding to the load monitoring input is returned to the transmission control device 30, and the returned monitoring data is transmitted to the operation terminal 31. The operation terminal 31 outputs a monitoring signal according to the transmission signal. The monitoring output is usually used to turn on and off the confirmation lamp. Further, the operation terminal 31 includes switches S ₀ of up to four circuits, the control terminal 32 can control the load L of up to four circuits, and the operation terminal 31 and the control terminal 32 each have a switch S _0. And a load number of 2 bits for individually recognizing the load L. Hereinafter, the address of the operation terminal 31 or the control terminal 32 will be referred to as a channel, and the channel and the load number will be collectively referred to as an address. That is, an individual address is assigned to each switch S ₀ and each load L.

In the illustrated remote monitoring and control system, a dimming control terminal 33 is connected to a signal line Ls. The dimming control terminal 33 controls the light output of the lighting load, which is a load. When the increase or decrease of the light output of the lighting load is instructed by the transmission signal Vs, the light output changes with time. When the stop is instructed by another transmission signal, the change of the optical output is stopped. The dimming control terminal 33 is associated with the dimming operation terminal 38,
The dimming operation terminal 38 is provided with an operation unit for instructing increase and decrease of the light output of the load L. When the operation unit is pressed, the dimming control terminal 33 changes the light output by a transmission signal. . When the operation of the operation unit is stopped (that is, when the pressing operation is stopped), the dimming control terminal 33 stops the change of the light output by another transmission signal. The dimming operation terminal 38 is also provided with an operation unit for turning on and off the load L. When the load L is turned off by operating this operation unit,
Next, when the load L is turned on, the load L is turned on with the previous light output. The previous light output is stored in each dimming control terminal 33.

In this type of remote monitoring and control system, the transmission control device 30 manages the correspondence between the address of the switch S ₀ and the load L.
If associates the address of the load L of the plurality of circuits as the relation data in the address of the switch S ₀ of 1 circuit 0, it is possible to collectively control the load L of the plurality of circuits in switches S ₀ 1 circuit It is possible. Such collective control includes group control and pattern control. In group control, a plurality of loads are controlled to the same control state, and in pattern control, a plurality of loads are controlled to a preset control state. The collective control operation terminal 39 for performing group control and pattern control uses an operation address defined as collective control, but other configurations are the same as those of other operation terminals. In the illustrated example, a collective control operation terminal 39 of the same type as the dimming operation terminal 38 is provided, and the collective control operation terminal 39 can simultaneously control a plurality of loads L. I have.

As described above, in order to perform pattern control,
In the transmission control device 30, the collective control operation terminal 3
The address of the load L of a plurality of circuits is added to the address of the
Must be registered in association with this type of setting operation.
The work is called pattern setting. In the following, the operation terminal
Set the pattern control switch provided at 31 to the pattern switch.
Switch, which is provided on the operation terminal 31 for individual control.
Switch S ₀Call. Also, group control
The setting operation to be performed is called group setting.

As shown in FIG. 8, the remote monitoring control system has two operation modes, a control mode for controlling the load L and a setting mode for performing pattern setting and group setting. That is, when the remote monitoring control system is operated, the transmission control device 30 first enters a normal control mode (S1), and sends a transmission signal in the dummy mode to the signal line Ls. If there is no interrupt signal (S2), a transmission signal in the dummy mode is repeatedly generated as it is (S3).
On the other hand, if there is an interrupt signal in step S2 (S
2) The operation terminal 31 is specified and a request from the operation terminal 31 is fetched (S4). Here, if the change of the operation mode is not requested (S5), the current operation mode is determined (S6), and if it is the control mode, the load L is controlled (S5).
7) If the mode is the setting mode, pattern setting or group setting is performed (S8). If a change in the operation mode is requested in step S5, the operation mode is changed according to the request (S9).

To perform pattern setting in the setting mode,
Manipulating the desired pattern switch, then operating the individual switches S ₀ associated with the load L to be controlled according to the pattern switch. Here, it is assumed that the relationship between each individual switch S ₀ and the load L is set first. According to such a procedure, the state of the load L according to the operation of the individual switch S ₀ is taken into the transmission control device 30 as related data, and the state of a plurality of loads L is associated with one pattern switch. Here, the switch S by the operation check display that is annexed to the switch S ₀ which associates with the load L to be controlled in the configuration mode
Only the state of the load L corresponding to ₀ is displayed, and the operation of the switch S ₀ does not control the load L.
That is, in the setting mode, all the switches S ₀ are dedicated to the setting operation, and the load L cannot be controlled in the setting mode.

[0013]

Since [0005] In the above configuration mode as to select the load L in the pattern control using the individual switches S _0, the load at individual switch S ₀ is while performing the pattern setting L Can no longer be controlled. Moreover, individual switch S ₀ is from being disposed generally away, there is a problem that can not be controlled in the load L for a relatively long period time-consuming in the pattern set.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a remote monitoring control system capable of performing pattern setting and group setting in a state where load control is possible. .

[0015]

According to a first aspect of the present invention, there is provided an operation terminal device having a switch and a unique address is set for each switch, and a control terminal to which a load is connected and a unique address is set for each load. And a switch connected to a signal line branching and connecting the operation terminal and the control terminal to generate control data for controlling the load based on monitoring data received from the operation terminal when the switch is operated, and the operated switch A transmission control device for transmitting control data to a control terminal connected to a load having a correspondence relationship with the load, and a plurality of loads being collectively controlled by operating one switch connected to a signal line. A setting terminal for generating related data and transferring and setting the related data to the transmission control device, wherein the monitoring data and the control data are transmitted to the transmission control device. The transmission control device transmits in synchronization with the transmission signal transmitted at predetermined time intervals, and the transmission control device synchronizes with the transmission signal during a period during which monitoring data or control data is not exchanged with the operation terminal or the control terminal. Then, related data is exchanged with the setting terminal. According to this configuration, when setting related data for operating a plurality of loads collectively with one switch in the transmission control device, the idle time during normal control without switching to the setting mode is set. Related data can be transferred.

According to a second aspect of the present invention, in the first aspect of the invention, when the start of transmission of the monitoring data is notified from the operation terminal in synchronization with the transmission signal, the transmission / reception of the related data is interrupted and the monitoring data is transmitted. The transmission / reception of the related data that has been interrupted after the transmission of a series of monitoring data and control data is restarted. According to this configuration, when the switch is operated to control the load during the transfer of the related data, the transmission of the related data is interrupted, and the load control is prioritized. Since the transmission of the data is resumed, there is an advantage that the related data can be transmitted using the idle time other than the period from the operation of the switch to the control of the load without hindering the control of the load.

According to a third aspect of the present invention, in the first or the second aspect of the present invention, the setting terminal includes: an operation unit for controlling a plurality of types of loads; a storage unit for storing a control state of each load; A data generation unit that generates relational data by using data related to the control state of the loads that are collectively controlled among the data stored in the storage unit. According to this configuration, the load can be actually controlled by the setting terminal, and the actual control state of the load is used as the related data. It is possible to set the related data after confirming the above, and there is an advantage that it becomes easy to set a desired light control light amount especially in the case of controlling the light control of a load.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the operation unit includes a display capable of displaying characters and figures,
An operation mode in which the data generation unit controls the load in response to the operation of the touch panel associated with the display content of the display unit, and the correspondence between the switch and the load, consisting of a transparent touch panel superimposed on the screen of the display unit It comprises a switch processing unit capable of selecting a setting mode for setting a relation as relation data. According to this configuration, if the screen is switched by a combination of the display and the touch panel, various kinds of operations can be performed, and there is an advantage that a relatively small but multifunctional setting terminal can be provided.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) In this embodiment, a dedicated setting terminal for pattern setting and group setting is connected to a signal line, and related data set by the setting terminal is transmitted to a transmission control device via a signal line Ls. And a data transfer procedure for transferring relevant data to the transmission control device in a state where load control is possible. That is, by performing the related data indicating the contents of the pattern setting and the group setting during the idle time when controlling the load, it is not necessary to switch the operation mode.

The transmission control device 30, as shown in FIG.
A signal processing unit 41 comprising a microcomputer;
1 operates according to the program written in the ROM 42. The signal processing unit 41 includes a driver / receiver 4
3, the signal line Ls is connected. Further, it is provided with EEPROMs 44a and 44b for holding related data, and a RAM 45 for storing the operation state of the load L and the like. Further, a signal line short detection / display circuit 46 is provided to detect and display a short circuit of the signal line Ls. Signal processing unit 41
Is composed of a microcomputer, so that it also includes an oscillation circuit 47 for generating a clock signal, a reset circuit 48 for initializing when power is turned on, and a power supply circuit 49.

Next, a procedure which is a feature of this embodiment will be described. The related data is transferred according to the procedure shown in FIGS. This procedure can be divided into three processes: a pre-process for starting the transfer of the related data, a transfer process for actually transferring the related data, and a post-process for ending the transfer of the related data. When starting the operation, the transmission control device 30 first sets the transfer state to "no transfer" to indicate that the related data is not transferred (S1). That is, the state becomes the same as the operation mode for controlling the load L in the conventional configuration, and the transmission signal in the dummy mode is repeatedly transmitted to the signal line Ls. If no interrupt signal is generated (S
2) It is determined whether or not the data is being transferred (S3). If the data is not being transferred, the transmission signal in the dummy mode is repeatedly generated as it is (S4).

On the other hand, in the pre-processing, since the setting terminal for transferring the relevant data to the transmission control device 30 generates an interrupt signal, the interrupt signal is detected in step S2. When the interrupt signal is detected, the setting terminal is specified and the interrupt request is determined (S5). This process is the same as that for controlling the load L. When the related data is transferred, there is a data transfer request from the setting terminal device to the transmission control device 30 (S6), so that the transfer state is set to “transferred” to indicate that the related data is being transferred. (S7). If there is no data transfer request in step S6,
Normal control of load L means load L
Is controlled (S8).

The transmission and reception of signals between the transmission control device 30 and the setting terminal are specifically performed as shown in FIG.
That is, the setting terminal generates an interrupt signal (R ₁ ), the transmission controller 30 sets an interrupt flag and performs interrupt polling (T ₁ ), and returns an address from the setting terminal. (R ₂ ). Upon acquiring the address of the setting terminal, the transmission control device 30 monitors the contents of the request from the setting terminal (T ₂ ). The setting terminal requests reception of related data for monitoring the request content from the transmission control device 30 (R ₃ ), and the transmission control device 30 receiving the request content releases the interrupt flag (T ₃ ). The transmission control device 30
Then, a 256-byte address area for storing the related data is secured in order to transfer the related data. In this embodiment, 256 bytes are called one page and are unitized, and the transmission control device 30 secures an address area of one page. When the address area of one page is secured, the address area for registering the related data is notified to the setting terminal (T ₄ ), and the transmission of the related data is instructed (T ₅ ). After instructing the transmission, the transfer status of the related data is monitored from the setting terminal (T ₆ ), and a notification that the related data can be transferred (that is, the transfer is performed) is returned in the setting terminal. Then (R ₄ ), the processing shifts to the transfer processing.

In the transfer process, the relevant data from the setting terminal is transferred to the transmission control device 30 (S9). here,
If the amount of data cannot be transmitted in a single transmission, only part of the data is transferred, and if the transfer of the related data has not been completed (S
10) An interrupt signal is generated again from the terminal, and the above processing is repeated to transfer related data. In particular,
The transmission control device 30 monitors how many bytes of data are transmitted from the setting terminal (T ₇ ) and returns a byte counter (R ₅ ). Thereafter, the related data is monitored (T ₈₁ ), and the set terminal transfers the related data of the number of bytes specified by the byte counter (R ₆₁ ). Here, the related data is divided into a plurality of pieces without transferring the entire data at once, and the transmission control device 3 is transmitted from the setting terminal until the transfer of the related data of the number of bytes specified by the byte counter is completed.
Transfer to 0 is repeated _{(T 81 ~T 8n, R 61} ~
R _6n ). Finally, the transmission control device 30 requests the setting terminal for a checksum of the relevant data (T ₉ ). When the checksum is returned (R ₇ ), the presence or absence of a transmission error is detected. The relation data includes a pattern number for distinguishing the type of pattern control, an address of a load L to be controlled, and control contents. In this manner, the transmission control device 30 sets a pattern control or group control table in accordance with the contents of the related data divided and transferred from the setting terminal to the transmission control device 30.

In the post-processing, the transfer state is set to no transfer.
This is a process (S11), and the transmission control device 30
After completing the data setting, monitor the transfer status of the terminal.
(T _Ten), Confirm that the transfer is completed (R₈). So
After that, a data transmission end instruction is transmitted (T₁₁), Relationship de
Set that all processing related to data transfer has been completed
Notify the terminal.

According to the above-described procedure, the control terminal transmits the related data for the pattern control and the group control during the idle time when the control data for the load L is not generated in the state where the control of the load L is possible. This can be transferred to the control device 30. That is, there is no need to switch between the control mode and the setting mode. As described above, in the present embodiment, the related data is divided into a plurality of pieces, and the related data is transferred from the setting terminal to the transmission control device 30 a plurality of times.
This is because if the related data of the same capacity is transferred at one time, the transfer processing time becomes longer, and a period during which the load L cannot be controlled normally may occur. Therefore, the related data can be transferred without causing a period in which the load L cannot be controlled by dividing and transferring the related data so as to use the idle time that is not used. Actually, the control of the load L is a short-time process, and there are many idle times that are not used for the control of the load L. If the related data is divided into 1-byte units and sequentially transferred to the idle time, It is possible to transfer related data without hindering the control of the load L. Further, in order to divide and transfer the related data, the transmission control device 30 holds the data on the transfer state. You can recognize. As a result, when the control of the load L is requested during the period in which the transfer state is “transferred”, the control of the load L is processed prior to the transfer of the related data, and after the control of the load L is processed, the control of the load L is performed again. By continuing the data transfer, the related data can be transferred without hindering the control of the load L.

The format of the data transferred between the setting terminal and the transmission control device 30 is as shown in FIG. 3, and this type of data is stored in the one-page address area from the lower side. They are stored sequentially.
That is, this data is a byte counter BC, a header HD for data identification, a destination address SA for transmitting data between terminals, a source address DA for transmitting data between terminals, and transfer data DT. ₁ to DT _n, consists checksum SUM, byte counter BC is stored in 00H of the address area, the header HD is the data is stored in the address area as that stored in 01H of the address area. However, when transmitting relationship data as described above, only the binary counter BC and the transfer data DT ₁ to DT _n and checksum SUM is used.

The setting terminal described above has a number of switches S
_A terminal provided with a function of setting relational data between ₀ and a number of loads L, or an interface for connecting a setting device or a computer device outside the remote monitoring control system to the remote monitoring control system. Can be used. (Embodiment 2) In Embodiment 1, the control state of the load L to be subjected to pattern setting and group setting is set while confirming the display contents on the setting terminal side, and the set related data is transmitted to the transmission control device 30. If the control state of the load L is only on / off, the load L can be used without any problem. However, when the load L is an illumination load and dimming control is performed, proper setting cannot be performed unless the actual dimming state is confirmed.

Therefore, in the present embodiment, a setting terminal 34 having the configuration shown in FIG. 5 is used. The setting terminal 34 has a function of not only performing pattern setting and group setting but also instructing control of various loads L. As the load L, an incandescent lamp, a fluorescent lamp having an inverter-type lighting device, a fan coil of an air conditioner, a ventilation fan, a speaker, an electric shutter, an electric curtain, or the like can be used.

The setting terminal 34 includes a liquid crystal unit 11 in which a backlight is integrated with a liquid crystal display, and a transparent touch panel 12 which is arranged so as to overlap the screen of the liquid crystal unit 11. The liquid crystal unit 11 is of a matrix display type in which a large number of pixels are arranged vertically and horizontally in a matrix, and a graphic is displayed by a combination of pixels. The touch panel 12 is of a resistance pressure-sensitive type in which a large number of contact portions made of transparent electrodes are arranged on a transparent sheet-like member, and when a finger or the like touches the sheet-like member, which part is touched is output.

The basic configuration is the same as that of the conventional operation terminal 31, and the signal line Ls connected to the transmission control device 30
And a transmission / reception circuit 21 for transmitting and receiving a transmission signal. The transmission / reception circuit 21 is connected to a main microcomputer 20 which is also used as a transmission processing unit and a switch processing unit. The main microcomputer 20 operates according to programs and data written in the flash memory 22. Address data as a terminal and function data for determining the function of the terminal are written in at least a part of the flash memory 22. Further, the flash memory 22 stores data prepared by the system such as various messages and symbols.

The main microcomputer 20 transfers data indicating the display contents of the liquid crystal section 11 to the liquid crystal controller 24 through the latch circuit 23. LCD controller 24 is D
A predetermined content is displayed at a predetermined position of the liquid crystal unit 11 using data registered in the RAM 25 in advance. DRAM2
The content of 5 can be set by the user as described later,
Touch panel 1 with main microcomputer 20 in setting mode
2 is stored in the DRAM 25, and when the touch panel 12 is operated with the main microcomputer 20 in the operation mode, the display content of the liquid crystal unit 11 is set using the data stored in the DRAM 25. The contrast of the liquid crystal unit 11 and the brightness of the backlight are automatically adjusted by controlling the contrast adjusting unit 26 and the backlight inverter circuit 27 by the main microcomputer 20. Further, a buzzer 28 is connected to the main microcomputer 20, and when a predetermined area of the touch panel 12 is touched or an erroneous operation is performed, the buzzer 28 is sounded to notify that an input has been received or that there has been an erroneous operation. . Here, it is desirable to set a sound different from the input reception and the erroneous operation.

The setting terminal requires a relatively large amount of power, for example, by providing a backlight in the liquid crystal unit 11. Therefore, an internal power source is not obtained from the signal line Ls, but a separately supplied 24 V AC is supplied to the power source circuit. The internal power is obtained by rectifying the voltage at 29 and stabilizing the voltage. The 24 V AC supplied to the power supply circuit 29 is obtained from a remote control transformer arranged in a distribution board or the like together with the transmission control device 30. The remote control transformer is conventionally provided to supply power to the remote control relay when a remote control relay (a relay that can be turned on and off by a switch provided separately without depending on a transmission signal) is used. By supplying 24 V AC output from the remote control transformer to the setting terminal, the setting terminal does not need to obtain internal power from a commercial power supply such as 100 V AC, and does not require a power transformer or a large smoothing capacitor. . 5 V, 1
Although a voltage such as 2 V or 20 V is used, since the voltage is stepped down from 24 V, a desired voltage can be obtained with a simple configuration in which a required number of voltage stabilizing circuits are provided.

As described above, by supplying a low-voltage AC power to the setting terminal, there is no need for an insulating separator for separating the power line from the signal line Ls which is a small power line. become. In other words, when the case of the setting terminal is installed on a wall or the like as an embedded type using an embedded box such as a switch box, and a small power line such as a commercial power supply and a signal line is installed in the embedded box. Is mixed, it is obligatory to place a separator in the embedding box to ensure safety. However, the power supply line supplies 24 V AC and the signal line L
Since s transmits a bipolar transmission signal of 24 V, a separator is not required even if the power supply line and the signal line Ls are mixed. In addition, the amount of heat generation is reduced because the amount of voltage drop at the setting terminal is small. In addition, since a step-down transformer is unnecessary, the size and weight can be reduced.

By the way, the setting terminal 34 described above has
Since a large number of loads L can be controlled by the table, and the control states of the loads L at each time point are stored in the DRAM 25, related data can be generated by using data stored in the DRAM 25. . And DR
Since the data stored in the AM 25 reflects the actual control state of the load L, it is possible to generate the related data after confirming the control state of the load L.
That is, if the setting terminal 34 is used, the relation data can be generated after the load L is actually controlled. After that, the transmission control device 30 is used in the transmission procedure described in the first embodiment.
The relevant data may be transferred to

Data is exchanged with the setting terminal in synchronization with the transmission signal during the period when data or control data is not being exchanged, and is used to operate multiple loads at once with a single switch. Is set in the transmission control device, there is an advantage that related data can be transferred during idle time during normal control without switching to the setting mode.

According to the second aspect of the present invention, when the start of monitoring data transmission is notified from the operation terminal in synchronization with the transmission signal, the transmission / reception of related data is interrupted, and the monitoring data is transmitted.
The transmission / reception of the related data that was interrupted after the transmission of a series of monitoring data and control data is resumed.When a switch is operated to control the load during the transfer of the related data, the transmission of the related data is started. Interruption gives priority to load control, and resumes transmission of related data after load control is completed, so idle time other than the period from switch operation to load control without interrupting load control Has the advantage that related data can be transmitted using

According to a third aspect of the present invention, the setting terminal comprises:
An operation unit that controls a plurality of types of loads, a storage unit that stores a control state of each load, and a relation using data related to a control state of a load that is collectively controlled among data stored in the storage unit. With a data generation unit that generates data, the load can be actually controlled by the setting terminal, and the control state of the actual load is used as related data, so when multiple loads are controlled collectively It is possible to set the related data after confirming what state it will be in, and it is easy to set the desired dimming light amount especially when controlling the dimming of the load. is there.

According to a fourth aspect of the present invention, the operation unit comprises a display capable of displaying characters and figures, and a transparent touch panel superimposed on the screen of the display. A switch processing unit that can select an operation mode for controlling a load in response to an operation of a touch panel associated with a display content and a setting mode for setting a correspondence between a switch and a load as related data is displayed. If the screen is switched by the combination of the device and the touch panel, various operations can be performed, and there is an advantage that a relatively small but multifunctional setting terminal can be provided.
