DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system including a plurality of lighting loads, wherein several lighting loads are controlled in relation to each other.

[0002]

2. Description of the Related Art Conventionally, a lighting interlocking system has been proposed in which some of a plurality of lighting loads are combined and controlled in association with each other. For example, when a human sensor detects the presence of a person in a predetermined area, a relatively wide range associated with the detection area may be illuminated with a plurality of illumination loads. In addition, when not only the human sensor but also a preset condition is satisfied (for example, when a switch is operated or the ambient illuminance falls below a set value), a plurality of lighting loads are controlled to a control state corresponding to the condition. Is thought to be. For example, if there are many lighting loads in a relatively large room, the illuminance due to natural light decreases with distance from the window,
It has been considered that a constant illuminance can be obtained in almost all areas in a room by dimming a lighting load which is an artificial lighting. In addition, turning on a lighting load in a place where no person is present causes wasteful power consumption. Therefore, it has been considered to turn on only lighting in a necessary place such as around a person.

As described above, when it is necessary to control a plurality of lighting loads in association with each other according to conditions, it is considered to use a multiplex transmission technique in order to make the association free and easy. That is, a lighting load is connected to a number of control terminals each having an address, and when the address included in the transmission signal received through the transmission line matches the preset address, the control load is connected to each control terminal. The lighting load is controlled according to the control data included in the transmission signal. Further, since the control terminals need to be associated with each other, a transmission unit is provided to have an association table in which the associated control terminals are registered. Therefore, when predetermined conditions such as operation of a switch, presence or absence of a person, and change in ambient illuminance are satisfied, the conditions are notified to the transmission unit, and the transmission unit refers to the related table and sets the related table. By transmitting a transmission signal designating the address of each of the control terminals to the transmission line, the lighting loads associated by the association table can be controlled simultaneously. In this case, the lighting load may be dimmed as needed.

Means for notifying the transmission unit of the establishment of the predetermined condition can be provided separately from the transmission path between the transmission unit and the control terminal. In general, a common transmission path is used. The multiplexing of the transmission lines (when controlling the lighting load, generally, a wired transmission line is used and the transmission lines are multiplexed by time division) to notify the satisfaction of the predetermined condition. In other words, a monitoring terminal having an address is also provided on the notification side of the satisfaction of the condition, and when the satisfaction of the condition is detected based on a monitoring input (a switch, a human sensor, an illuminance sensor, etc.) to the monitoring terminal, from the monitoring terminal, The transmission unit is notified through the transmission path. in this way,
By associating the monitoring terminal with the control terminal in the above-described association table, it becomes possible to control a desired lighting load to a desired control state when a predetermined condition is satisfied.

[0005]

By the way, in order to create the above-mentioned association table, under what conditions are the monitoring inputs to the respective monitoring terminals, what kind of lighting load is connected to which control terminal, It is necessary to decide whether to control to a proper control state. As described above, since many elements are intricately intertwined with each other, the operation of creating the related table becomes very troublesome.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lighting interlocking system capable of automatically associating a plurality of lighting loads.

[0007]

According to a first aspect of the present invention, there is provided an identification code setting section in which a unique identification code is defined, a transmission signal including an identification code is transmitted and received via a transmission line, and the transmission signal is included in the transmission signal. A transmission processing unit that extracts a control code included in the transmission signal when the identification code matches the identification code set in the identification code setting unit; and controls a lighting load based on the control code extracted by the transmission processing unit. A plurality of lighting units each including a lighting control unit, at least some of the lighting units are provided with a human sensor for detecting the presence or absence of a person as a detection area near an illumination range due to an illumination load, and When the presence of a person is detected by the human sensor, the lighting load of another lighting unit previously associated with the association table is turned on. In the light interlocking system, together with to provide the associated table to a transmission unit for exchanging data via a transmission path between all lighting units,
Each lighting unit is provided with an illuminance sensor, and when setting the related table, each lighting unit notifies the transmission unit of the identification code and the presence / absence of a human sensor, and the transmission unit identifies the identification code of the lighting unit having the human sensor. Is written in the related table, and then the lighting load is sequentially turned on for each lighting unit of the identification code written in the related table, and the illuminance detected by the illuminance sensor provided in the other lighting unit when the lighting load of each lighting unit is turned on. Is greater than or equal to a predetermined value, the identification code of the lighting unit is written in the association table in association with the identification code of the lighting unit having the lighting load being turned on.

According to this configuration, each illumination unit is provided with an illuminance sensor, and each illumination unit notifies the transmission unit of the identification code of the illumination unit and the presence / absence of a human sensor. Since the lighting unit sequentially instructs the lighting unit having the human sensor to turn on the lighting load, and when the output of the illuminance sensor is equal to or more than a predetermined value in the lighting unit around the lighting load, the identification code is transmitted to the transmission unit. The transmission unit can automatically know the identification codes of the lighting units that need to be turned on at the same time around the human sensor. That is, it is possible to automatically associate a plurality of illumination loads relatively close to each other without any manual operation.

According to a second aspect of the present invention, in the first aspect of the invention, when setting the related table, the illumination load of each illumination unit having a human sensor is sequentially turned on, and the illuminance is detected by the illuminance sensors of the other illumination units. When the illuminance detected by the illuminance sensor becomes equal to or more than a predetermined value only when the illumination load is lit, the identification code of the illuminating unit is written into the related table. .

According to this configuration, when the lighting unit having the human sensor is associated with another lighting unit, the lighting load is repeatedly turned on and off, so that the illuminance detected by the illuminance sensor is caused by ambient light. It is possible to identify whether the lighting load is caused by lighting, and the possibility of incorrectly associating lighting units is reduced. According to a third aspect of the present invention, in the first or second aspect of the present invention, the lighting control unit can adjust the lighting load, and when setting the related table, the lighting load of each lighting unit including the human sensor is set. Are sequentially turned on, and when the illuminance is detected by the illuminance sensors of the other lighting units, the detected illuminance is written into an association table of the transmission unit together with the identification code of the illumination unit having the detected illuminance equal to or greater than a predetermined value, and the transmission unit has one When the presence of a person is detected by the human sensor of the lighting unit, the lighting load of the other lighting unit previously associated by the association table is lit at a lower output as the detected illuminance written in the association table is lower. is there.

According to this configuration, when the lighting load provided in the lighting unit having the motion sensor is turned on, the illuminance distribution due to the lighting load is detected and written in the related table. Since the lighting load of the lighting unit is dimmed, it is possible to obtain an illuminance distribution in which the vicinity of the lighting unit having the human sensor is brightest, and the illuminance decreases as the distance from the location increases. That is, it is possible to illuminate such that only the surroundings of a person are bright and the distance from the person becomes darker.

[0012]

FIG. 1 shows the overall configuration of this embodiment. As shown, in this embodiment, two types of lighting units 2 and 3 are connected to a signal line Ls connected to the transmission unit 1. The lighting units 2 and 3 are shown in FIGS.
As shown in FIG. 2, a transmission processing unit 21 connected to the signal line Ls for transmitting and receiving a transmission signal transmitted through the signal line Ls, and a ROM storing an identification code uniquely defined for each of the lighting units 2 and 3 And a code storage unit 22 as an identification code setting unit. The transmission processing unit 21 compares the identification code included in the transmission signal with the identification code stored in the code storage unit 22.
The lighting load 4 is controlled based on the control data included in the transmission signal. The identification code is already set at the time of shipment from the manufacturer, and a different code is used for each of the lighting units 2 and 3, such as a serial number. The lighting load 4 is controlled via the lighting control unit 23. Here, the illumination control unit 23 may use not only a unit that controls turning on and off the illumination load 4 but also a unit that can perform dimming control.

The lighting unit 2 has only an illuminance sensor 24 for detecting the ambient illuminance.
Includes a human sensor 25 for detecting the presence or absence of a person in a predetermined detection area in addition to an illuminance sensor 24 for detecting ambient illuminance. Therefore, the code storage unit 22 also stores a type code corresponding to the configuration of the lighting units 2 and 3 in addition to the identification code described above. In the transmission processing unit 21, the illuminance sensor 2
The illuminance detected by 4 is transmitted to the transmission unit 1, and when the human sensor 25 detects entry or exit of a person into the detection area, the transmission unit 1 is notified.
The lighting units 2 and 3 are housed in the fixture body, respectively.
It can be treated as one lighting fixture.

Here, in order to transmit and receive a transmission signal between the transmission unit 1 and the lighting units 2 and 3, a transmission signal including an identification code, control data, and a return time slot is transmitted from the transmission unit 1 and transmitted. The control signal is transmitted from the transmission unit 1 to the lighting units 2 and 3 by the transmission signal, and the monitoring data is transmitted from the lighting units 2 and 3 accessed from the transmission unit 1 in synchronization with the return time slot of the transmission signal. It is returned to unit 1.

As the transmission signal from the transmission unit 1, a signal that sequentially changes identification data so as to poll each of the lighting units 2 and 3 cyclically can be used. In this case, when each of the lighting units 2 and 3 is polled (that is, when the identification code of the transmission signal matches the set identification code), the illumination units 2 and 3 return the monitoring data in synchronization with the return time slot of the transmission signal. .

Further, a transmission signal which is not normally accessed by any of the lighting units 2 and 3 is transmitted at regular time intervals,
When the lighting units 2 and 3 transmit the monitoring data, they generate an interrupt signal synchronized with the transmission signal, and the transmission unit 1 receiving the interrupt signal sets the transmission signal to the search mode, and sets the transmission signal to the search mode. When the received lighting units 2 and 3 return the identification code, the transmission unit 1
May access the lighting units 2 and 3 using the identification code.

The former procedure is effective when the number of the lighting units 2 and 3 under the control of the transmission unit 1 is small, and the control is easy because the procedure is relatively simple. On the other hand, the latter procedure is slightly complicated, but the time from the generation of the monitoring data to the reception of the monitoring data by the transmission unit becomes almost constant regardless of the number of the lighting units 2 and 3. That is, the latter procedure is effective when the number of lighting units 2 and 3 is large.

As shown in FIG. 3, the transmission unit 1 transmits a transmission signal to the signal line Ls and has a function of receiving monitoring data returned in a time slot for returning the transmission signal. A section 11 is provided, and a related table 12 described in the related art is provided. The association table 12 is formed by a rewritable memory, and stores identification codes of the lighting units 2 and 3 that are controlled in conjunction with each lighting unit 2 including the human sensor 25. In FIG. 1, the numerical value enclosed by "" indicates the identification code. Each lighting unit 2 including the human sensor 25
Are associated with other lighting units 2 and 3. The association table 12 is specifically as shown in Table 1, and for example, for the lighting unit 3 having the identification code “1”, the lighting units 2 having the identification codes “2”, “3” and “4”, 3
Is associated with.

[0019]

[Table 1]

Next, the operation of this embodiment will be described.
First, when power is supplied to the lighting units 2 and 3 after the transmission unit 1 and the lighting units 2 and 3 are connected to the signal line Ls, the lighting units 2 and 3 make a transmission request to the transmission unit 1 and transmit The identification code and the type code are transmitted to the unit 1. Here, if the transmission unit 1 polls each lighting unit 2, 3 cyclically, each lighting unit 2, 3 returns an identification code and a type code in a return time slot when accessed. . On the other hand, when generating an interrupt signal, each of the lighting units 2 and 3 generates an interrupt signal upon power-on (by detecting a transmission signal transmitted on the signal line Ls), and thereby the transmission unit An identification code and a type code are transmitted to the device 1. When the transmission unit 1 receives the identification code and the type code from the lighting units 2 and 3, if there is a type code of the lighting unit 3 including the human sensor 25, the identification code is stored in the association table 12.

The creation of the relation table 12 is performed by the following processing. First, the lighting loads 4 provided on the lighting units 3 stored in the association table 12 are turned on one by one. In the lighting period of the lighting load 4 of each lighting unit 3, the output of the illuminance sensor 24 is detected in the other lighting units 2 and 3, and when the illuminance detected by the illuminance sensor 24 is equal to or larger than a preset threshold, the transmission is performed. Unit 1
, The identification codes of the lighting units 2 and 3 are transmitted. When the transmission unit 1 receives this identification code, it writes it in the association table 12 as being related to the lighting unit 3 that is lighting the lighting load 4 (that is, the identification code of the lighting unit 3 that is lighting the lighting load 4 is displayed in the table). 1, the illuminance sensor 2
The identification code transmitted from the lighting units 2 and 3 based on the output of (4) becomes the one in the column of "related identification code").

The relation table 12 is created in such a manner that when the lighting load 4 of the lighting unit 3 is turned on, the illuminance detected by the illuminance sensors 24 of the surrounding lighting units 2 and 3 is equal to the illuminance. This is based on the relationship that the load becomes higher as the distance from the lighting unit 3 that turns on the load 4 becomes shorter. That is, since it is only necessary to detect the degree of closeness when associating the adjacent lighting units 2 and 3, it is possible to associate the lighting units 2 and 3 with each other by using the association table 12 set as described above. You can. Here, since the illuminance detected by the illuminance sensor 24 includes not only the light output from the illumination load 4 but also the ambient external light, the illumination load 4 is turned on to remove the influence of the external light. In the lighting unit 3, the lighting load 4 is repeatedly turned on and off, and the transmission unit 1 does not transmit the identification code when the lighting load 4 is turned off, and transmits the identification code only when the lighting unit 4 is turned on. In the association table 12. In this way, it is possible to prevent the lighting loads 2 and 3 from being associated with each other due to external light.

By performing the above-described processing individually for each of the lighting units 3 provided with the human sensor 25, the lighting units 2 and 3 for turning on the lighting load 4 in association with the detection of a person by each lighting unit 3 are automatically turned on. Can be selected.
That is, the creation of the association table 12 is automated. After the association table 12 is created as described above, the operation is the same as that of the conventional configuration. When a person is detected by the human sensor 25, the illumination load 4 of the illumination unit 3 is turned on,
The identification code is transmitted from the lighting unit 3 to the transmission unit 1. The transmission unit 1 checks the received identification code against the association table 12, and if there is a matching identification code, controls the lighting units 2 and 3 included in the "related identification code" to turn on the lighting load 4. Transmit the code. In this way, the plurality of lighting loads 4 can be turned on in association with the detection of a person by the human sensor 25. The same applies to the case of turning off the light. When the lighting unit 3 including the motion sensor 25 detects that no person is detected and turns off the lighting load 4, the transmission unit 1 is notified of the turning off. The other lighting loads 4 can be turned off with reference to the lighting loads.

(Embodiment 2) In Embodiment 1, the illumination load 4
Is an example in which only turning on and off can be performed. In the present embodiment, not only turning on and off but also dimming is performed. Therefore, the lighting control unit 23 of each of the lighting units 2 and 3 can adjust the lighting load 4. That is, the dimming control of the lighting load 4 is performed by controlling the phase using a switching element such as a triac or controlling the output power using an inverter circuit. Other configurations are the same as in the first embodiment.

In the present embodiment, the relation table 1
2 is associated not only with the identification code of the lighting units 2 and 3 but also with the dimming level. Such an association table 12
Is shown in Table 2. The associated table 12 actually stores the illuminance detected by the illuminance sensor 24. By dimming the light output of each of the lighting units 2, 3 with respect to the detected illuminance, the lighting of the associated lighting units 2, 3 is performed. Sometimes, the light output of the lighting unit 3 having the motion sensor 25 becomes the largest, and the lighting unit 3 which is the center of the
The light output is set to decrease as the distance from the camera increases. With such control, the illuminance can be reduced as the distance from the position of the human sensor 25 increases.

[0026]

[Table 2]

In order to create such an association table 12, in the operation of creating the association table 12, after the lighting units 3 having the motion sensors 25 are registered in the transmission unit 1, On the other hand, when the lighting of the lighting load 4 is instructed, not only the identification code but also the illuminance detected by the illuminance sensor 24 is received from the other lighting units 2 and 3 and written into the association table 12. The detected illuminance is expressed in such a manner that the illuminance at a position at a predetermined distance from the illumination unit 3 having the human sensor 25 is defined as 100%. In this way, since the approximate distance from the central lighting unit 3 can be determined by obtaining the detected illuminance, the light output of the lighting load 4 is controlled to decrease as the distance increases.
Actually, the transmission unit 1 gives an instruction to each of the lighting units 2 and 3 so that the detected illuminance becomes the dimming level. With such control, the human sensor 2 that detects a human
5, the lighting units 2 existing within a predetermined distance range from the lighting unit 3,
3, the lighting load 4 is turned on, and the light output decreases as the distance from the lighting unit 3 increases. That is, it is possible to provide illumination such that the center is bright and the periphery is dark. Moreover, since the central portion turns on the illumination load 4 by detecting the presence of a person, the illuminance near the location where the person exists is high, and the illuminance decreases as the distance from the person increases. Other configurations and operations are the same as those of the first embodiment.
