DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring and control system which transmits a transmission signal by a time division multiplex transmission system, and which can control a load by operating a switch using the transmission signal. The present invention relates to a remote control terminal for transmitting and receiving a transmission signal through a wireless transmission path using a radio wave as a medium used in a system.

[0002]

2. Description of the Related Art A remote monitoring control system having a configuration shown in FIG.
0581). In the illustrated remote monitoring control system, a two-wire signal line Ls connected to the transmission control device 30 is used.
, An operation terminal 31 and a control terminal 32 are connected. Here, the operation terminal device 31 and the control terminal device 32 are multi-drop connected to the signal line Ls. Individual addresses are set for the operation terminal 31 and the control terminal 32, respectively, and the transmission control device 30 individually recognizes the operation terminal 31 and the control terminal 32 using those addresses. The operation terminal device 31 includes a switch SW as an operation unit. The control terminal 32 has a load control relay Ry provided with a contact for opening and closing a path for supplying power AC to the load L.
Is provided.

Next, the operation of the remote monitoring and control system will be briefly described. The transmission control device 30 controls the signal line Ls
The transmission signal Vs of the format shown in FIG. That is, the synchronization signal SY indicating the start of signal transmission, the mode data MD indicating the mode of the transmission signal Vs, the address data AD for individually calling the operation terminal 31 and the control terminal 32, the operation terminal 31 and the control terminal 32 Data CD for giving an instruction to the terminal, checksum data CS for detecting a transmission error, operation terminal 31 and control terminal 3
2 which is a time slot for receiving a return signal (monitoring data) from the signal return period WT.
V), and data is transmitted by pulse width modulation (FIG. 17 (b)).
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. When there is monitoring data to be captured and transmitted, the transmission signal V
During the s signal return period WT, the monitoring data is returned as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via an appropriate 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 instructs the operation of the load control relay Ry or instructs the change of the dimming signal according to the received control data CD, and the operation terminal 31 outputs a monitoring signal for confirming the operation according to the received control data CD. I do.

On the other hand, the transmission control device 30 normally transmits a transmission signal Vs in which the mode data MD is in the dummy mode at regular time intervals (constant polling). When transmitting information, an interrupt signal as shown in FIG. 17C 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. When the transmission control device 30 receives the interrupt signal, it sets the mode data MD to the interrupt polling mode and sets the upper half of the address data AD (address data A).
The transmission terminal transmits the transmission signal while sequentially increasing the upper 4 bits (where D is 8 bits), and the upper 4 bits of the address data AD of the transmission signal in the transmission mode of the interrupt polling mode are transmitted in the operation terminal 31 which generates the interrupt signal. When the upper four bits of the address set in the operation terminal 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 16 operation terminals 31 that have generated the interrupt signal, the operation terminal 31 can be found in a relatively short time.

When the transmission control device 30 obtains the address of the operation terminal device 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. . 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, the operation terminal 3
The information transmission from the transmission control device 1 to the transmission control device 30 is completed by four signal transmissions from the transmission control device 30 to the operation terminal 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.

[0007] In short, when input data is generated by operating the switch SW, the operation terminal device 31 returns monitoring data corresponding to the input data to the transmission control device 30, and the transmission control device 30 responds to the monitoring data by the control terminal 30. Container 32
The control terminal 32 controls the load L by opening and closing the contacts of the load control relay Ry.

When the above-described remote monitoring and control system is used, the correspondence between the addresses of the operation terminal 31 and the control terminal 32 is simply set in the transmission control device 30 in the form of a table. Can be changed, and the address of a plurality of loads L can be associated with the address of one switch SW. Therefore, the switches SW and the loads L can be freely associated with each other according to the purpose of use. It has the convenience of increasing the degree of freedom in controlling L. Here, the control of the load L of one circuit by one switch SW is individually controlled, and the load L of a plurality of circuits is controlled by one switch SW.
Group control to collectively control
Controlling the loads L of a plurality of circuits to a preset state by one switch SW is called pattern control. Further, an address set in association with each switch SW, an address used for individual control is called an individual address, an address used for group control is called a group address, and an address used for pattern control is called a pattern address. Here, as the individual address, the same address is assigned to the switch SW and the load L that have a correspondence relationship, and whether the switch SW (that is, the operation terminal device 31) or the load L (that is, the control terminal device 32) is a part of the address data. It is identified by the type data that constitutes it. Therefore, the operation terminal device 31
If the same address is set in the control terminal 32 and
The operation terminal 31 and the control terminal 32 correspond one to one.

[0009]

As described above, the remote monitoring and control system is capable of controlling the load L with a high degree of freedom, and is gradually spreading, but is used in applications where the number of circuits of the load L is relatively small. At present, it is not widely used. In other words, when the number of circuits of the load L is relatively small, a conventional power supply line connected to a series circuit of a commercial power supply and a load is laid in a wall, and power to the load is turned on and off using a wall switch. At present, wiring systems are used.
On the other hand, even for small and medium-sized applications, the remote monitoring and control system can be used to prevent forgetting to turn off the lighting load of multiple circuits and to easily control indoor lighting between daytime and nighttime. Therefore, there is an increasing demand for a change work for replacing a conventional wiring system with the above-described remote monitoring and control system because of its high convenience. However, for a general user, if a long time is required for the change work, the work will be hindered. Therefore, a remote monitoring control system that can quickly perform the change work is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a remote monitoring system capable of quickly performing a change work for replacing an old wiring system by partially using the old wiring system. A control system and a remote control terminal used therefor are provided.

I have. A remote control relay 36 for stepping down the commercial power supply voltage
Are provided to supply the power for driving the load control relay Ry and the power for generating the dimming signal of the dimming control terminal 32c. That is, in the illustrated example, the lighting equipment (not shown) is turned on and off using the relay control terminal 32b and the load control relay Ry, and the light output of the same lighting equipment is controlled by the dimming control terminal 32.
3 shows a configuration in which control is performed using c. The dimming amount of the dimming signal output from the dimming control terminal 32c is instructed by a terminal configured for dimming. Also, the relay terminal 32
a is used for controlling other loads.

By the way, a wireless transmission path using a radio wave as a medium is formed between the repeater 34 and the remote control terminal 35, which is the gist of the present embodiment. In other words, a wireless transmission path is used as a part of the transmission path between the transmission control device 30 and the remote control terminal 35. The remote control terminal 35 has various forms as described below, and a remote control terminal for dimming can be configured in addition to the configuration described later. However, the remote control terminal 35 has substantially the same configuration as the other remote control terminals 35. , An on / off switch for turning on / off the lighting load, an up switch for instructing an increase in the light output, a down switch for instructing a decrease in the light output, and a plurality of indicator lights in a straight line. The only difference is that the light output is a measure of the light output depending on the number of lights.

As shown in FIG. 2, at least one series circuit of the commercial power supply AC and the load L can be connected to the remote control terminal 35. The number of circuits is one, two, or three. Some remote control terminals 35 are provided with a switch SW and some are not provided with a switch SW.
(A) As shown in (b), there are those provided with the indicator light La, and those without the indicator light La. As shown in FIGS. 3 (c) to 3 (f), the switch SW has one switch SW.
There are two, three, four, and the same number of indicator lamps La as the switches SW. However, the number of connectable circuits and the number of switches SW do not always match. The remote control terminal 35 which does not have the switch SW but has the indicator light La includes those having two indicator lights La and those having three indicator lights La as shown in FIGS. 3 (g) and 3 (h). That is, as shown in FIGS. 3 (a), 3 (g), and 3 (h), in those having the indicator lamps La without the switches SW, the indicator lamps La for the number of connectable circuits are provided. In the illustrated example, the decorative plate 52 is attached to the front of the body of the remote control terminal 35.

As described above, the remote control terminal 35 has a switch SW and an indicator lamp La, and the number of circuits that can be connected thereto.
Although there are many types, but the basic configuration is the same, a description will be given below by taking as an example a combination in which the number of switches SW and the number of circuits are the largest. That is, four switches SW
And a configuration that can connect up to three series circuits of the commercial power supply AC and the load L.

The remote control terminal 35 shown in FIG. 4 includes four switches SW1 to SW4, and a contact r of a load control relay.
1 to r3 are provided. Each of the contacts r1 to r3 can be opened and closed independently, and the opening and closing of the contacts r1 to r3 are controlled by a signal processing unit 10 comprising a microcomputer.
Is determined. A circuit corresponding to the contact r1 is provided with an on-time power supply circuit 12 inserted between the series circuit of the AC power supply AC and the load L and the contact r1, and is connected in parallel with the contact r1 during an off-time. A power supply circuit 13 is provided. Power is supplied to the on-time power supply circuit 12 from the commercial power supply AC through the load L when the contact r1 is on, and power is supplied to the off-time power supply circuit 13 from the commercial power supply AC and the load when the contact r1 is off. Therefore, an internal power supply is generated by the on-time power supply circuit 12 and the off-time power supply circuit 13. That is, the internal power supply of the remote control terminal 35 can be obtained from the commercial power supply AC, and the internal power supply can be obtained regardless of the opening and closing of the contact r1.

The remote control terminal 35 is provided with a radio transmission section 14 for transmitting and receiving a transmission signal using a radio wave as a medium between the remote control terminal 35 and the transmission signal transmitted and received via the radio transmission section 14.

The address setting unit 15 has switch addresses individually associated with the switches SW1 to SW4 and individual contacts r1 to r3. The attached relay address can be set. That is, two types of addresses can be set.

Since the illustrated remote control terminal 35 has four switches SW1 to SW4, four switches La1 to La4 are provided corresponding to the switches SW1 to SW4, respectively. These indicator lights La
1 to La4 are provided to indicate whether the corresponding load is turned on or off by the operation of the switches SW1 to SW4, and emits, for example, red (indicating on) and green (indicating off). The indicator lamps La1 to La4 are configured as a set of diodes, and the on / off of the load is represented by a color. Here, the display lamps La1 to La4 are connected to the signal processing unit 10 via the state output unit 17, and the display state is determined by the signal processing unit 10.

The setting of the address in the address setting unit 15 may be automatically performed by transmitting / receiving a transmission signal to / from the transmission control device 30 or may be performed using a separately provided setting device. The function to automatically set the address only works. The function of automatically setting an address will be described later. First, an address setting technique using a setting device will be described. Setting device and remote control terminal 3
Information is exchanged between the device 5 and 5 using an optical wireless signal using infrared light as a medium. That is, the remote control terminal 35 includes the optical wireless transmission / reception unit 16 for transmitting and receiving an optical wireless signal. The setting device is conventionally provided, and a display device 37 such as a liquid crystal display device as shown in FIG.
, And an operation unit (not shown) of a push button switch for instructing writing, correction, and reading of the content in the address setting unit 15 of the remote control terminal 35. The illustrated example is an example in which the switch SW1 is assigned for group control, and the contacts r1 to r3 are set to be individually turned on and off.

In this setting, as shown in FIG. 5 (a), the terminal corresponding to the operation terminal is selected in the type field F1 as the type data of the terminal (underline is displayed on the character of the switch), In the four-level address field F2, "G" indicating group control is displayed at the uppermost level (allocated to the switch SW1), and "1" indicating a group number is displayed. These displays are selected by operating an operation unit (not shown). When the information determination operation is performed after the information to be assigned to the switch SW1 is displayed on the display 37, the switch SW in the address setting unit 15 is transmitted through the optical wireless transmission / reception unit 16.
The switch address corresponding to 1 is written for group control. The switch address can be set not only for group control but also for individual control and pattern control.

Similarly, the terminal corresponding to the control terminal is selected in the type field F1 (relay T /
U is underlined), Address field F
Addresses are assigned to the top three rows of 2, respectively.
Here, the address is represented by two numerical values with a hyphen between them, such as “0-1”. The value before the hyphen is the channel, and the value after the hyphen is the load number. This is 1
This is because a configuration is adopted in which four switches or loads can be connected to a maximum of four terminals. Each terminal is identified by a channel, and the switch or load of each terminal is identified by a load number. It is identified by. As described above, after the address is set in each of the top three rows of the address field F2, when the content determination operation is performed, the relay address corresponding to each of the contacts r1 to r3 in the address setting unit 15 through the optical wireless transmission / reception unit 16 is obtained. Each is written.

By the way, as shown in FIG. 6, the repeater 34 forming a wireless transmission path with the remote control terminal 35
A wireless transmission unit 21 for exchanging a transmission signal using a radio wave as a medium with the remote control terminal 35 is provided. The wireless transmission unit 21 is connected to a relay processing unit 20 including a microcomputer, and the relay processing unit 20 transmits the signal line Ls
Connected to. That is, the transmission / reception unit 22 connected to the transmission control device 30 and the wireless transmission unit 21 for transmitting / receiving a transmission signal between the remote control terminal 35 transmit / receive data via the relay processing unit 20. A storage unit 23 is connected to the illustrated relay processing unit 20, and the storage unit 23 has a function of storing a table similar to a table in the transmission control device 30. That is, the illustrated repeater 34 has the same function as the transmission control device for the wireless transmission path, and the pattern control and group control using each remote control terminal 35 are performed through the transmission control device 30. Without using the repeater 34.

By performing such processing, the transmission control device 3
Thus, distributed processing can be performed without passing 0, traffic on the signal line Ls is reduced, and the load on the transmission control device 30 is also reduced. That is, a transmission signal between the remote control terminals 35 forming a wireless transmission path with the repeater 34 is:
Processing can be performed only by the repeater 34 without transmitting the signal line Ls. However, when the number of circuits of the load L is relatively small, the storage unit 23 may not be provided. Also, since the transmission control device 30 has a higher-level relationship with the repeater 34, the table of the transmission control device 30
4 holds the contents of the storage unit 23. Repeater 3
4 is supplied from a commercial power supply AC, and an internal power supply is generated through a power supply circuit 24. Further, a separate antenna can be connected to the wireless transmission unit 21 via the external antenna connection unit 25.

The repeater 34 is housed in a case 41 having the shape shown in FIG. Two attachment pieces 42 protruding from the outer peripheral surface of the container body 41 are provided so as to be fixed to suspension bolts arranged in the ceiling. FIG. 7 shows only the mounting piece 42 on the front surface (the upper surface when installed) of the body 41, but the other mounting piece 42 projects from the rear surface of the body 41. A power supply terminal 4 to which a power line of a commercial power supply AC is connected is provided on one side surface of the housing 41.
A feed terminal 4 for feeding and wiring the electric wire;
4 is provided on the other side of the body 41. Further, a connection terminal 45 which is a threaded terminal for connecting the signal line Ls and an antenna connection terminal 46 serving as the external antenna connection portion 25 are provided on the back surface (the upper surface in FIG. 7) of the body 41.

Next, the operation of automatically setting an address in the address setting section 15 of the remote control terminal 35 will be described. This process is performed when the operation of the remote monitoring and control system is started, that is, immediately after the power is turned on and at least one of the switch address and the relay address is not set in the address setting unit 15. FIG. 8 shows the processing flow.

When the power is turned on (S1),
The transmission control device 30 confirms all addresses used in the system (S2). Here, not only individual addresses but also group addresses and pattern addresses are checked. On the other hand, if an unset relay address exists in the remote control terminal 35 (S3), the remote control terminal 35 requests the transmission control device 30 to set the address. At this time, the number of unset relay addresses is also notified. In response to this request, the transmission control device 30 extracts an unused address from the address of the control terminal (T / U) (S4), transmits it to the remote control terminal 35, and sets a relay address (S5).

Next, the remote control terminal 35 checks whether there is an unset switch address (S6). If there is an unset switch address, first, it is determined whether or not the number of relay addresses matches the number of switch addresses. Is determined (S7). If they match (that is, if the number of switches and the number of contacts are the same), the relay address is registered as a switch address. On the other hand, if the number of switches does not match the number of contacts, the transmission control device 30 is requested for a group address. The transmission control device 30 confirms the unused group address by this request (S9), transfers this group address to the remote control terminal 35 and records the switch address (S10), and furthermore, all the relay addresses of the remote control terminal 35 Is associated with the group address set as the switch address as a group (S11).

When the switch address is associated with the relay address in a one-to-one or one-to-many manner as described above, the setting of the address in the remote control terminal 35 is completed (S12). Further, when the group address is a switch address, the group address is transmitted to the transmission control device 30, and the relay address received from the transmission control device 30 is notified that the relay address is subjected to the group control, and the group registration is performed. Then, the table of the transmission control device 30 is updated (S13). If the relay address is already registered in step S3 and the relay address is duplicated (S15), or if the switch address is already registered in step S6 and the switch address is duplicated (S1).
6) In each case, as an error, the two light-emitting diodes constituting the indicator lights La1 to La4 are turned on and off (S1).
7, S18).

According to the above procedure, the remote control terminal 35
If the number of switch addresses provided in the transmission control device 30 is equal to or less than the number of relay addresses and the transmission control device 30 has an unused address, the switch address and the relay address are automatically set. That is, the load L can be controlled by operating the switches SW1 to SW4 without setting the address immediately after turning on the power. In this setting, the remote control terminal 3 provided with the switches SW1 to SW4
Only the load L connected to 5 is to be controlled, but if another load L is to be controlled, the correspondence of addresses in the transmission control device 30 may be changed. If a switch address or a relay address has already been set, the address is used.

The mounting frame is generally fixed corresponding to a mounting hole formed in the wall surface. As described above, since the body 51 can be coupled to the mounting frame provided for the wiring device and fixed to the wall surface, the mounting can be performed using the normal mounting member for the wiring device without using a dedicated member. can do. The decorative plate 52 described above is formed so as to cover the front surface of the mounting frame and the periphery of the mounting hole formed in the wall surface.

One transmission / reception window 57a is used for setting a switch address, and the other transmission / reception window 57b is used for setting a relay address. That is, in the setting device provided conventionally, as described above, the addresses of the operation terminal device and the control terminal device can only be set individually, so that the transmission / reception windows 57a and 57b corresponding to the switch address and the relay address are set.

Power supply terminal 5 for connecting a power supply line connected to a series circuit
8 are provided in three sets. That is, in the present embodiment, three series circuits of the commercial power supply AC and the load L can be connected, and thus three sets of power supply terminals 58 are provided. The power supply terminal 58 is a so-called quick-connecting terminal that holds the power supply wire inserted into the wire insertion hole provided in the body 51 by the spring force of the locking spring, and simply inserts the power supply wire into the wire insertion hole. The power supply line is locked so that electrical connection and mechanical holding can be performed. To release the connection state of the power supply line to the power supply terminal 58, the locking state by the locking spring is released by pressing a release button provided near the wire insertion hole, and the power supply line may be pulled out. The structure of this type of quick-connecting terminal is well known, and a detailed description is omitted.

As described above, the power supply line to which the series circuit of the commercial power supply AC and the load L is connected is connected to the remote control terminal 35, and no other connection is required.
As shown in FIG. 10A, instead of the conventional wall switch 50 connected to the power supply line Lp so as to turn on and off the commercial power supply and the load (lighting load) L as shown in FIG. The remote control terminal 35 of the embodiment can be connected to the power supply line Lp. In addition, since the body 51 of the remote control terminal 35 is attached to the mounting frame for the wiring device, the work is performed simply by replacing the wall switch 50 with the old one, and the indoor work is completed in a short time. Will end.

On the other hand, when using the remote control terminal 35 of this embodiment, a repeater 34 is required.
It is necessary to construct a remote monitoring and control system to which is connected.
Since it is necessary to construct a board for storing 0 and the like, and it is not necessary to provide a wiring for falling down in the wall, the construction can be performed in a relatively short time. In other words, the work of installing the signal line Ls and the like of the remote monitoring and control system becomes relatively simple, and the remote control terminal 35 is simply replaced with the wall switch 50. Can be easily replaced with a remote monitoring control system. That is, the remote control terminal 3 uses the mounting hole B on the wall surface on which the old wall switch 50 is mounted.
5 can be attached. Note that J in the drawing is a joint box for branching the power supply line Lp. Even if the remote monitoring and control system is replaced in this way, as described above, the load L is allocated to the switches SW1 to SW4 immediately after the power is turned on. The same control can be performed, and the setting operation of the address is performed, and the correspondence of the address is set in the transmission control device 30, so that the degree of freedom of the control mode of the load L is increased.

Here, since the remote control terminal 35 and the repeater 34 receive power from the commercial power supply AC, the problem of running out of batteries does not occur. That is, the remote control terminal 3
It is difficult to secure the power of the indicator lamps La1 to La4 when a battery is used in 5, but the power source for lighting the indicator lamps La1 to La4 can be easily secured because the power is obtained from the commercial power supply AC. .

(Second Embodiment) In the first embodiment, in order to enable control of the load L by operating the switches SW1 to SW4 without performing an address setting operation, a temporary operation is performed when the power is turned on. Although the process of automatically setting the address is performed, in the present embodiment, the address can be used even when the address is not set in the address setting unit 15.

That is, the remote control terminal 35 of the present embodiment
When the address is not set in the address setting unit 15, the signal processing unit 10 in
The configuration is such that the contacts r1 to r3 of all the load control relays provided on the remote control terminal 35 are turned on and off.
The procedure shown in FIG. 11 will be described in more detail. First, when any one of the switches SW1 to SW4 is operated (S
1) Inquiring whether or not the corresponding switch address is set in the address setting unit 15 (S2). If the switch address is set, the transmission signal is transmitted to the transmission control device 30 using the switch address. Is transmitted, and the load associated with the transmission control device 30 is controlled (S3). On the other hand, when the switch address is not set, when the switches SW1 to SW4 are operated, all the contacts r1 to r3 provided in the remote control terminal 35 including the switches SW1 to SW4 are turned on / off collectively (S4). . That is, the load L can be turned on and off by operating the switches SW1 to SW4 without using an address. Other configurations and operations are the same as those of the first embodiment.

In the above embodiments, the switches SW1 to SW4 and the indicator lamp L
Although an example is shown in which four each of a1 to La4 are provided and up to three series circuits of the commercial power supply AC and the load L can be connected,
As shown in FIG. 3, there are various combinations of switches and indicator lights, and the number of connectable circuits is also one.
Up to three circuits can be appropriately configured.

For example, if the remote control terminal 35 does not have a switch and an indicator light and has a configuration in which a load of two circuits can be connected, the external appearance shown in FIG. 12 is obtained. In this configuration, since there is no switch, only the transmission / reception window 57b for setting a relay address is provided on the front surface of the housing 51. Two sets of power terminals 58 are provided on the rear surface of the body 51. In this type of remote control terminal 35, since no switch and indicator light are provided, the status output unit 1
7 will not be provided. Thus, the remote control terminal 35 having no switch or indicator light can be used in a form as shown in FIG. In the example shown in FIG. 13, a remote control terminal 35 to which a load L of one circuit is connected,
The one that connects the load L of the circuit is used. In this configuration, since no switch is provided, the load L is controlled by another remote control terminal 35 or another operation terminal 31 connected to the signal line Ls.

Further, when the remote control terminal 35 has only one switch SW and can be connected to a load of three circuits, the configuration shown in FIG. 13 can be adopted, and two switches SW are provided. In addition, when connecting loads of three circuits, the configuration shown in FIG. 14 can be adopted. The configuration example of the remote control terminal 35 described above is merely an example, and the number of switches, the number of indicator lights, and the number of load circuits can be appropriately combined.
