2. Description of the Related Art Generally, when controlling a lighting load, a switch or a sensor for giving a control instruction is inserted between the lighting load and a power source. However, when controlling a large number of lighting loads individually, When controlling multiple lighting loads at once,
There is a problem that the wiring system becomes complicated and the construction and management become troublesome.

On the other hand, it has been proposed to reduce wiring by transmitting a lighting control signal for controlling a lighting load through a path different from that of a power source using a data transmission technique. For example, by connecting a plurality of terminals to a central monitoring and control board via a set of signal lines, the central monitoring and control board sends and receives data to and from each terminal by the polling / selecting method. A centralized system for controlling the lighting load connected to the has been proposed. In addition, a plurality of terminals are connected to one set of signal lines without providing a central monitoring control panel, and data is exchanged between the terminals by the contention method to control the lighting load connected to each terminal. There are also distributed systems. The terminal is equipped with switches and sensors as information input means that can give control instructions to the lighting load. The correspondence between the switches and sensors and the lighting load to be controlled is the central monitoring control panel in the centralized system. Is set as a table in the distributed system, and is set in the distributed system by registering the terminal device to which the lighting control signal is transmitted with the terminal device provided with the switch and the sensor.

The centralized system will be described in more detail.
You. In the centralized system, as shown in FIG.
Central monitoring and control panel 11 via signal line Ls for multiple illuminators
Ingredient L ₁, L_Two, ... are connected to each lighting fixture L.₁,
L_Two, ... are added to the lighting load 12 as shown in FIG.

Control twelve. The lighting load 12 is turned on to the terminal device 10.
・ In addition to turning off the lights, dimming control of the lighting load 12 is performed.
Things have been suggested. Also, the lighting fixture L₁, L_Two,…
The sensor 13 is also provided in the ...
When the state of the surrounding environment that is output satisfies the default condition,
The detection output generated from the sensor 13 is transmitted to the terminal device 10.
Input as monitoring data. As the sensor 13,
For example, when there is a person in the detection area, the detection output is
Living person detection sensor, ambient illuminance is below a certain illuminance
An illuminance sensor that generates a detection output is used. Ma
Although not shown, a wall switch is used instead of the sensor 13.
Depending on the case, the monitoring data may be given to the terminal device 13.
The address setting unit 10a adds a unique address to the terminal device 10.
The dress is set.

The illumination control signal is, as shown in FIG. 11B, address data AD for individually designating each terminal device 10.
And control data CD instructing how to control the lighting load 12, and a return waiting period WT for sending the monitoring data input to the terminal device 10 to the signal line Ls. Further, although not shown, generally, a start signal indicating the start of one frame of the illumination control signal and error check data for detecting a transmission error are also provided. If the terminal device 10 only turns on / off the lighting load 12, the control data CD is two kinds of data for instructing turning on / off.
In the case of dimming control of No. 2, it becomes data for instructing the dimming level.

As shown in FIG. 11 (a), the above-mentioned illumination control signal is sent from the central supervisory control board 11 to the signal line Ls at a constant cycle, and the address data AD is cyclically changed (see FIG. 11 ( a) L ₁ , L ₂ , ... Means a lighting control signal having address data AD corresponding to the lighting fixtures L ₁ , L ₂ ,. In the terminal device 10, when the address data AD of the lighting control signal transmitted through the signal line Ls matches the preset own address, the control data CD of the lighting control signal is fetched to control the lighting load 12. Alternatively, the monitoring data from the sensor 13 or the like is fetched and returned to the central monitoring control panel 11 during the return waiting period WT. The central monitoring control panel 11 is provided with a table in which a plurality of terminals 10 are associated in advance by addresses, and when the monitoring data is input, the terminals associated with the terminals 10 that have generated the monitoring data by the table are provided. Control data corresponding to the monitoring data is transmitted to 10. For example, if it is assumed that the predetermined lighting load 12 is turned on when the presence of a person in the detection area is detected by the human detection sensor as the sensor 13, which lighting load 1 is detected when the person is detected by the sensor 13.
2 depending on whether to turn on the sensor 13 on the table.
The terminal device 10 on the side and the terminal device 10 on the side of the lighting load 12 are associated with each other by an address. Where the table is 1
A plurality of lighting loads 12 can be associated with one sensor 13. Therefore, when a person is detected by one sensor 13, it is possible to sequentially transmit the lighting control signal instructing the plurality of terminals 10 to turn on the lighting loads 12, and turn on the plurality of lighting loads 12.

Next, the distributed system will be described. In the distributed system, as shown in FIG.
A plurality of luminaires L ₁ , L ₂ , ... Are connected to s, and each luminaire L ₁ , L ₂ , ... Is illuminated according to the illumination control signal in addition to the illumination load 12 as in the centralized system. Load 12
The terminal device 10 for controlling the That is, a lighting device L ₁ , such as the central monitoring and control panel 11 of the centralized system,
There is no one that supervises L ₂ , ..., and each lighting fixture L ₁ , L
₂ , ... are on equal terms. In this case, since the table cannot be set in the central monitoring control panel 11, the terminal device 10 has the address of the terminal device 10 to be associated with in addition to the unique address in the address setting unit 10a. For example, when the presence of a person in the detection area is detected by the person detection sensor as the sensor 13, the predetermined lighting load 12 is turned on, and in the terminal device 10 having the sensor 13, the person is detected by the sensor 13. The address of the other party of the terminal device 10 having the lighting load 12 to be turned on may be set in the address setting unit 10a in addition to its own address depending on which lighting load 12 is turned on. is necessary. Further, since the terminals 10 are equal, the terminal 10 having the sensor 13 that has generated the detection output acquires the transmission right, and the signal line Ls is connected until the terminal 10 finishes transmitting the illumination control signal. Occupy.

In the distributed system, since it is necessary to set its own address and the address of the other party in each terminal device 10, the terminal devices 10 arranged in a distributed manner.
It is very troublesome to perform the address setting work for each one. Therefore, it is considered that a memory switch is used as the address setting unit 10a and the address setting data is transmitted to each terminal device 10 via the signal line Ls. That is, different addresses are set for all the manufactured terminal devices 10 like the serial number, and each terminal device 10 connected to the signal line Ls is designated by using this address, whereby each terminal device 10 is designated. The address actually used for control is set in the address setting unit 10a. By doing so, the address setting work can be collectively performed at a place distant from the terminal device 10, and the setting work becomes easy.

On the other hand, it may be considered that the terminals 10 having the lighting loads 12 that are turned on at the same time are grouped without setting their own address and the address of the other party, and a group number is set for each group. There is. In this case, the luminaire L _1, L _2, ......, as in FIG. 12 (b), the address setting portion 10b, the luminaire L _1, L _2, ......
The group number indicating the group to which the group belongs is stored. The address setting unit 10b can set the group numbers of a plurality of groups.

A concrete configuration of the terminal 10 is shown in FIG. That is, the microprocessor 16 is connected via the transmitting / receiving unit 15 connected to the signal line Ls, and the microprocessor 16 performs the process as the terminal device 10 by the program stored in the memory 17. Further, the microprocessor 16 is provided with an interface 18 for taking in the detection output from the sensor 13 as monitoring data, an interface 19 for connecting the address setting unit 10b, and an interface 20 for controlling the lighting load 12. Further, a DC power supply 21 for supplying power to the internal circuit of the terminal device 10 is provided.

As shown in FIG. 14B, the illumination control signal when the group number is used is sensor type data SD indicating the type of sensor, and control data CD instructing whether the lighting load 12 is turned on or off. , Address setting unit 1
A variable length signal containing the group numbers GN ₁ , GN ₂ , ... Stored in 0b is used. Also in this case, similarly to the centralized system, an end signal which includes a start signal and error check data, which are not shown, and which indicates the end of the frame because of a variable length is also provided. For example, when a detection output is generated from the sensor 13, the group numbers are 1, 5,
Assuming that the lighting loads 12 of 9 and 10 are turned on, the sensor type data SD is a human detection sensor, and the control data C
D is turned on, and the illumination control signals with the group numbers GN ₁ , GN ₂ , ... As ₁ , ₅ , 9, 10 are transmitted. That is, each time the detection output from the sensor 13 is generated / disappeared, the illumination control signal is transmitted as shown in FIG. 14A (in the figure, it is shown that the illumination control signal is generated from the lighting fixture Li).

This lighting control signal is received by all the terminals 10 on the signal line Ls including the terminal 10 that generated the lighting control signal. As shown in FIG. 15, each terminal device 10 is provided with a group management table 14 having a field for writing ON / OFF information for each group,
When the group numbers GN ₁ , GN ₂ , ... Of the lighting control signal match the group number set in the address setting unit 10b, if the control data CD is an instruction to turn on, the group management table 14 corresponds to the group number. 1 is added to the value of the field to be set, and 1 is subtracted if the control data CD indicates OFF. That is, when the sensor 13 of the terminal device 10 shown in FIG.
The contents of the group management table 14 of the terminal device 10 are as shown in FIG.

When the content is written in the group management table 14 by the lighting control signal, the terminal 10 adds the values of the fields of the group management table 14 and determines whether the added value is 0 or greater than 0. The added value is 0
When it is larger, it means that the lighting load 12 is instructed to be turned on in any of the groups to which the terminal 10 belongs, so that the lighting load 12 is turned on and the added value is 0.
At this time, since the lighting load 12 is instructed to be turned off in the group to which the terminal 10 belongs, the lighting load 12 is turned off.

In the method using the group number, the lighting fixtures L ₁ , L ₂ , ... Having the sensor 13 generating the detection output are used.
Then, when the detection output from the sensor 13 is generated, it is adopted on the assumption that the lighting load 12 provided in the lighting equipment L ₁ , L ₂ , ... Is turned on. Here, the address setting unit 10b can be used as either a mechanical switch such as a DIP switch or a digital thumbwheel switch, and a memory switch. When the memory switch is used, an optical wireless signal or a signal is used. It is possible to use a setting signal transmitted via the line Ls.

By using the above-described centralized system or distributed system, it is possible to save energy by preventing unnecessary lighting loads 12 from being turned on. That is,
As shown in FIG. 16, the lighting fixtures L ₁ , L ₂ , ...
... is provided and a human detection sensor for detecting the presence or absence of a person is provided as the sensor 13 in the lighting equipment L ₁ , L ₂ , ..., and while the human detection sensor detects the presence of a person in the detection area. The lighting load 12 is turned on,
By turning on only the lighting load 12 near the human detection sensor or a small number of lighting loads 12 having a predetermined positional relationship with the human detection sensor, it is possible to turn off the lighting load 12 at a location that does not require lighting. Therefore, unnecessary power consumption can be suppressed. In FIG. 16, a region surrounded by a broken line is a range in which a person exists, and the lighting load 12 of the lighting fixtures L ₁ , L ₂ , ...

[0016]

By the way, there are cases where different departments in an office coexist on the same floor in an office. Now, it is assumed that two departments live together on the same floor, and areas occupied by them are zones ZA and ZB as shown in FIG. Further, the zone ZA is assumed to be located near the entrance E. In this case, lighting load lighting fixtures La ₁ , La ₂ , ..., Lb for each department
There are times when you want to control ₁ , Lb ₂ , .... That is, the lighting fixtures La ₁ , La ₂ , ... Of the zones ZA, ZB.

_In some cases, you may want to turn on ₂ , ... (Fig. 17
(C)).

Alternatively, as shown in FIG. 18, when the same department occupies the zones ZA and ZB which are spatially separated, if a person exists in one of the zones ZA and ZB, the other zone ZA and ZB. Some lighting fixtures L

Common zones ZAc, which are shared as passages in B and ZC,
When ZBc and ZCc are adjacent to each other, the lighting fixtures Lac and Lb of the common zones ZAc, ZBc and ZCc are selected depending on which zone ZA, ZB and ZC a person is in.
In some cases, it may be desired to turn on c and Lcc. For example, if the shared zone ZAc is on the entrance / exit side, when a person is present in the zone ZC, the lighting fixture Lcc of the shared zone ZCc is used.
Is lit, and whether there is a person in zone ZB or shared zone Z
Common zone ZB if lighting device Lcc of Cc is lit
There is a case where it is desired to perform control such that the lighting fixture Lbc of c is turned on, and if a person is present in the zone ZA or the lighting fixture Lbc of the common zone ZBc is turned on, the lighting fixture Lac of the common zone ZAc is turned on. .

The various controls as described above are performed by, for example, FIG.
As described above, two illumination control systems A and B each including the central monitoring control boards 11a and 11b are provided, and the respective illumination control systems A and B are provided.
Lighting fixtures La ₁ and L connected to the signal lines Lsa and Lsb of
_{a 2, ......, Lb 1,} Lb 2, the ...... both zones ZA, Z
It can be realized by arranging so as to straddle B. Alternatively, as shown in FIG. 21, the number of lighting fixtures L ₁ , L ₂ , ... Connectable to one signal line Ls is increased (that is,
It is also conceivable to arrange the lighting fixtures L ₁ , L ₂ , ... so as to straddle both zones ZA, ZB by increasing the number of addresses and the number of group numbers.

However, if one lighting control system includes a lighting fixture that extends over a plurality of zones, the management of the range to which the lighting fixture belongs is troublesome, and it becomes difficult to change the arrangement. Further, since the illumination control signal is attenuated with distance due to the impedance of the signal line, the extension distance of the signal line is limited, and it may be difficult to wire the signal line at a distant place.

The present invention has been made in view of the above reasons, and an object thereof is to intervene between a plurality of illumination control systems having an illumination load and to provide an illumination control signal between the illumination control systems. By enabling delivery, it is possible to apparently extend the signal line with almost no change to the specifications of each lighting control system.

As shown in FIG. 3, if it is necessary to transfer illumination control signals to each other among three or more illumination control systems A, B, and C, each of the pair of illumination control systems A, B, and C can be used. The lighting repeaters 1ab, 1bc, 1ca may be inserted between them. FIG.
Shows the case of three lines, but the same idea can be applied to the case of four lines or more. Also, although the centralized system has been described, even in the case of the distributed system, the respective lighting fixtures La ₁ , La ₂ , ..., La _n , Lb ₁ , L.
When the addresses are individually set to b ₂ , ..., Lb _n , the above-mentioned technical idea can be applied.

(Embodiment 2) In the first embodiment, the lighting repeater 1 is provided independently, but any one of the lighting fixtures La is provided.
₁ , La ₂ , ..., La _n , Lb ₁ , Lb ₂ , ..., L
_If the lighting repeater 1 is built in b _n , the lighting repeater 1
Since it is not necessary to install it separately, it saves space and facilitates construction.

Further, as shown in FIG. 1, the lighting repeater 1 is composed of an input / output unit 2 connected to the signal lines Lsa and Lsb, a distribution information table 3 and a relay processing unit 4.
The relay processing unit 4 is realized by a microcomputer,
Lighting fixtures La ₁ , La ₂ , ..., La _n , Lb ₁ , Lb
₂ , ..., Lb _n are connected to the signal line Ls.
The transmitting / receiving unit 15, the microprocessor 16 and the memory 17 are connected to a and Lsb. That is, the terminal 10
In the memory 17, a program that functions as the lighting repeater 1 is installed, and the transmission / reception unit 15 is configured to be connectable to the signal lines Lsa and Lsb of different lighting control systems A and B,
Furthermore, if the distribution information table 3 is also stored in the memory 17,

As shown in FIG. 4, it becomes possible to incorporate the terminal device 10 having the function of the lighting repeater 1 in any one of Lb _n . Other configurations and operations are the same as those of the first embodiment.

(Third Embodiment) In the first embodiment, when there are three or more lighting control systems, the lighting repeater is interposed between the signal lines of each pair of lighting control systems. That is, if there are three lighting control systems, three lighting repeaters are required. Adopting such a connection relationship has the advantage that the same technology can be applied to expand the lighting system regardless of the number of lighting control systems. On the other hand, multiple lighting repeaters are required. However, since the processing content of the relay processing unit is the same in any lighting repeater, if the number of lighting control systems that need to exchange lighting control signals with each other is determined, the distribution information table Only the number of lighting control systems may be set, and the relay processing unit may also be used. Based on such knowledge, when the illumination control signals are exchanged among the three illumination control systems A, B, and C, as shown in FIG. Lines Lsa, Ls
b and Lsc are connectable, and the distribution information table 3
Can be set as shown in Table 2. The other configurations and operations are the same as those in the first embodiment, and thus the description thereof is omitted.

[Table 2]

(Embodiment 4) In each of the embodiments described above,
The centralized system was explained. In this embodiment, as shown in FIG. 6, a case where the lighting repeater 1 is applied to a distributed system will be described. Here, an example using a group number as a distributed system is shown. That luminaire La _1, La ₂ to light up _{simultaneously, ......, La n, Lb 1} , L
b ₂ , ..., Lb _n are grouped and a group number is set for each group.

When each illumination control system A, B transfers an illumination control signal to the other illumination control system A, B, a group number designating the destination illumination control system A, B is set. That is, in the same illumination control system A, B, 1, 2, ...
If it is necessary to transfer the illumination control signal to other illumination control systems A and B, the destination illumination control systems A and B are designated. For example, lighting control system B
When a detection output is generated in the lighting fixture Lb ₂ of
If the luminaires Lb ₁ and Lb ₂ of the luminaire control system B and the luminaire La ₁₀ of the luminaire control system A are turned on, the luminaire Lb ₂ includes b ₁ and b ₂ as group numbers B → A: a. Set ₁₀ (here, the transfer source is also described in addition to the transfer destination). Specifically, "1",
“2” and “B → A: 10” are described.

Now, when a detection output is generated by the sensor in the lighting fixture Lb _2, the signal line Lsb of the lighting control system B is connected to the conventional sensor type data S as shown in FIG. 7A.
D, control data CD meaning ON, group numbers GN _B1 and GN _B2 in lighting control system B, and lighting control system B
To the lighting control system A, the lighting control signal including the transfer instruction data TD indicating the transfer to the lighting control system A and the group number GN _A1 in the lighting control system A is transmitted. In the repeater 1 for lighting, the signal line L
When the lighting control signal transmitted through sb is temporarily stored and the transfer instruction data TD is detected in the lighting control signal, the group numbers GN _B1 , GN _B2 and the transfer instruction data TD of the lighting control system B are detected from the lighting control signal. Omitted, Figure 7
As shown in (b), the lighting control signal including only the group number GN _A1 of the lighting control system A as the group number is supplied to the signal line Lsa.
To send to. That is, from the lighting repeater 1 to the signal line Lsa
The illumination control signal sent to the device is composed of sensor type data SD, control data CD and group number GN _A1 .
In this way, the lighting fixtures L of both lighting control systems A and B
a ₁ , La ₂ , ..., La _n , Lb ₁ , Lb ₂ ,.
It is possible to combine Lb _n into one group.
Lighting fixtures La ₁ and La from the lighting control system A to the lighting control system B
_The same applies when controlling ₂ , ..., La _n , Lb ₁ , Lb ₂ , ..., Lb _n .

By the way, in the lighting repeater 1, when the transfer source and the transfer destination in the transfer instruction data TD are the same,
The transfer instruction data TD may be ignored and the lighting control signal may be processed so as not to be transferred to the other lighting control systems A and B. Alternatively, when the lighting repeater 1 is inserted between the two lighting control systems A and B, even if the transfer instruction data TD is inconsistent, if the transfer instruction data TD exists, another lighting control system is present. The lighting control signal may be interpreted as being transferred to A and B, and may be automatically transferred to other lighting control systems A and B.

As shown in FIG. 8, there are three or more lighting control systems A, B and C, and the lighting repeaters 1ab and 1bc are inserted between the respective lighting control systems A, B and C, and It is also possible to construct an illumination system in which the illumination control system B is interposed between the illumination control systems A and C. In this case,
Allowing the transfer of the lighting control signal from the lighting control system A to the lighting control system C over the lighting control system B, or adjoining the lighting control system A,
Whether to allow the transfer of the lighting control signal only between B and C can be selected by setting the lighting repeaters 1ab and 1bc.

(Embodiment 5) In the terminal 10 of the distributed system shown as the prior art, the power source of the internal circuit is obtained from the DC power source 21 which is fed by a system different from the signal line Ls. As described above, the power of the internal circuit of the terminal device 10 may be obtained through the signal line Ls. It is also possible to obtain the power supply for the internal circuit of the terminal device 10 from the power supply that supplies the lighting load 12. Alternatively, the lighting repeater 1
From the terminal 10 to the signal line Ls.
Then, the voltage signal may be sent to the signal line Ls by controlling the line voltage of the signal line Ls by using this DC voltage. As described above, if the power source of the terminal device 10 is obtained from the outside or the lighting control signal is transmitted only by controlling the line voltage of the signal line Ls in the terminal device 10, the power source having a large capacity is supplied to the terminal device 10. Since it is not necessary to hold the device, the terminal device 10 can be downsized and the cost can be reduced.

In each of the above-described embodiments, a human detection sensor is illustrated as the sensor 13 which is the information input means. However, an illuminance sensor that detects the ambient illuminance or the dimming state of the lighting load 12, a sensor that detects temperature or humidity, etc. Alternatively, or instead of the sensor 13, an on / off instruction from an infrared remote controller or a wall switch may be input to the terminal device 10 as monitoring data. By replacing the human detection sensor with an illuminance sensor, it is possible to turn on the required lighting load 12 according to the ambient illuminance. Also, if the lighting load 12 is dimmed not only by turning on and off, the indoor window can be controlled. It is also possible to perform control so as to obtain uniform illuminance in the vicinity and the part far from the window.
