Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control device provided with a terminal which can set an address with an operation device (remote controller).

[0002]

2. Description of the Related Art A lighting control device in which a lighting load is turned on and off by a remote controller for a lighting fixture disposed on a ceiling is disclosed in, for example, Japanese Patent Application Laid-Open No. 3-250589. I have. In such a lighting control device, a switch operation of a remote controller is associated with turning on / off a lighting load of a lighting fixture. Therefore, address data is set for each lighting fixture, that is, for each terminal of the lighting control device.

Conventionally, setting of address data in each terminal has been performed by a mechanical switch such as a dip switch. However, terminals are often installed above the ceiling,
In this case, the operator has to enter the ceiling and operate the switch, which makes the setting operation inconvenient and takes time for the setting operation. In addition, the amount of work on site, such as checking the address data of the terminal, is increased, and there is a possibility that erroneous settings may occur. Therefore, as disclosed in Japanese Patent Application Laid-Open No. 8-140169 (prior art), it has been proposed to set the address of a terminal using a remote control type address setting device.

[0005] As shown in FIG. 5, the address setting device 50 uses a setting operation section 51 to input an identifier for identifying each terminal device and address data to be set in the terminal device. Then, the identifier input by the setting operation unit 51 and the address data are associated with each other and input to the address table 52. Then, when setting the address data in the terminal device, when the identifier of the desired terminal device is inputted by the selecting operation section 53, the address data corresponding to the identifier is read from the address table 52, and the read address data is read. The address data is transmitted from the transmission / reception unit 54 as a wireless signal. That is, registration work in the address table 52 is performed in a place where no terminal is installed, and address data can be set in the terminal by simply inputting the identifier of the terminal at the site. As a result, the on-site work is greatly simplified, the work time is shortened, and the setting error of the address data is reduced.

[0005]

Since the address setting device 50 of the prior art is a dedicated setting device for setting the address of the terminal device, the address setting device 50 can be used for maintenance work such as replacement or change of the terminal device.
If the address setting device 50 is inadequately managed and is lost, there is a disadvantage that the address setting is hindered.

In the prior art, since the terminal can set the address at any time by the address data sent from the address setting unit 50, there is a possibility that the terminal set at the address is erroneously set to another address.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a lighting control device capable of performing address setting and lighting control of a lighting load with a single remote controller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, a first embodiment of the present invention will be described.

FIG. 1 is a block diagram of a lighting control device according to a first embodiment of the present invention, FIG. 2 is a schematic external view of a terminal, and FIG. 3 is a block diagram of the terminal.

In FIG. 1, a lighting control device 1 includes a transmitter 2, a receiver 3, a terminal 4, a lighting fixture 5 and a main control device 6.

The transmitter 2 is a wireless transmitter, and transmits a control signal or an address signal by infrared rays or the like. The control signal includes an address signal and a dimming signal, and dims or blinks the lighting load 19 of the lighting fixture 5. In the present embodiment, the dimming signal is the lighting load 1
9 is made to blink (ON / OFF). The address signal specifies the terminal device 4 and the lighting equipment 5. The transmitter 2 is provided with a display unit (not shown) so that the transmitted and received signals are displayed on the display unit.

When a control signal is transmitted by the transmitter 2, the switch operation is performed, for example, in the order of a leader code, a custom code, an ON / OFF code, and address data. When an address signal is transmitted by the transmitter 2, the switch operation is performed, for example, in the order of a leader code, a custom code, an address setting code, and address data. Where the leader code is
The custom code is a code that prepares the receiver 3 and the terminal 4 for the transmitter 2 to start transmission, and the custom code is a code assigned to the manufacturer and used to avoid interference with other transmitters. It is.

The receiver 3 has a light receiving window 3 a for receiving the radio signal transmitted from the transmitter 2, converts the received radio signal into a digital signal, and transmits the digital signal to the terminal 4. The receiver 3 is arranged on the ceiling 7 such that the light receiving window 3a is located on the ceiling surface 7a. And transmitter 2
Transmits a wireless signal toward the light receiving window 3a.

The terminal device 4 is disposed, for example, on the back side of the ceiling 7, as shown in FIG. 2, has an external switch 8 for setting an address, a power supply terminal 9, and a load terminal 1.
0, a transmission terminal 11, and an input terminal 12. The switch 8 includes dip switches 8a,..., 8a, and the terminal 4 includes the dip switches 8a,.
The address can be set by turning on and off the switch. The power terminal 9 is electrically connected to the commercial AC power supply Vs, the load terminal 10 is electrically connected to a lighting device (not shown) of the lighting apparatus 5, the transmission terminal 11 is electrically connected to the main controller 6, and the input terminal 12 is electrically connected to the receiver 3. ing. The outside of the terminal 4 is grounded, and the receiver 3 is grounded by being connected to the terminal 4 via the ground line l.

Then, as shown in FIG.
In addition to the switch 8, the receiving interface 1
3, transmission interface unit 14, address setting unit 1
5, a storage unit 16, a control unit 17, and a relay 18.

The receiving interface unit 13 includes the receiver 3
Is input and transmitted to the address determination unit 15. Further, it is configured to transmit the address signal returned from the address determination unit 15 to the receiver 3. The transmission interface unit 14 includes the main controller 6
The digital signal transmitted from the address determination unit 15 is input and transmitted to the address determination unit 15, and the address signal returned from the address determination unit 15 is transmitted to the main control device 6.

The address determining section 15 determines the digital signal transmitted from the receiver 3 or the main controller 6. That is, when the digital signal is only the address signal, it is determined that the address is set for the terminal device 4, and the transmitted address is stored in the nonvolatile storage unit 16 as its own address. Thereby, the address setting for the terminal device 4 is performed. The storage unit 16 is formed so that the latest address is always rewritten. Therefore, even if the address is set in the terminal 4 by the switch 8, the address of the terminal 4 is set by the address signal transmitted by the transmitter 2. Then, when the digital signal is a control signal, its own address stored in the storage section 16 is read, and it is determined whether or not the address of the control signal matches its own address. When the address of the control signal matches its own address, the control unit 17 is configured to perform an operation based on the control signal.

The control unit 17 includes a CPU (not shown) and a RAM (not shown).
And a ROM or the like, and is configured to open and close the relay 18 in accordance with the dimming signal of the control signal when the address determination unit 15 determines that the address signal of the control signal is its own address. That is, the dimming signal is ON
If it is a code, the relay 18 is turned on, and the dimming signal
If it is an FF code, the relay 18 is turned off.

The lighting fixture 5 is a direct mounting fixture disposed on the ceiling surface 7a, and has a lighting device (not shown) and a lighting load 19 such as a straight tube fluorescent lamp disposed therein. When the relay 18 of the terminal device 4 is turned on, the lighting device turns on the commercial AC power supply Vs.
The lighting load 19 is turned on, and the lighting load 19 is turned on. When the relay 18 is turned off, the lighting device stops being supplied with power from the commercial AC power supply Vs, and stops operating. As a result, the lighting load 19 is turned off. That is, the lighting load 19
Flashes when the relay 18 is turned on and off.

Although one lighting device 5 is connected to the load terminal 10 of the terminal 4 in FIG. 1, a plurality of lighting devices 5 may be connected to the load terminal 10. Further, the terminal 4 may be provided with a plurality of relays 18. Also,
Instead of the relay 18, a phase control device may be provided.
In this case, the dimming signal is a phase code instead of the ON / OFF code. The phase controller changes the phase angle of the AC voltage of the commercial AC power supply Vs according to the phase code, and the lighting load 19 is dimmed.

The main controller 6 sends a control signal for controlling the lighting of the lighting load 19 or an address signal for setting the addresses of the terminal 4 and the luminaire 5 in the same manner as the transmitter 2. In the main controller 6 as well, the lighting load 1
9 and the address setting of the terminal 4 is possible. The address signal from the main controller 6 is transmitted in the order of, for example, a leader code, a custom code, and an address setting mode transition code.

Next, the operation of the first embodiment will be described.

When the address setting of the terminal 4 and the lighting equipment 5 is performed after the installation of the lighting control device 1, an address signal is transmitted from the transmitter 2 to the light receiving window 3 a of the receiver 3. The address signal received from the light receiving window 3a is
The signal is converted into a digital signal by the receiver 3, transmitted, and input to the address determination unit 15 via the reception interface unit 13 of the terminal device 4.

The address judging section 15 judges the input digital signal, and if the digital signal is an address signal, stores it in the storage section 16 as its own address. Thereby, the address setting for the terminal device 4 and the lighting equipment 5 is performed. Then, the address determination unit 15 returns the address signal stored in the storage unit 16 from the reception interface unit 13 to the receiver 3. The receiver 3 transmits the returned address signal to the transmitter 2 from the light receiving window 3a.

The display unit of the transmitter 2 displays the returned address signal. Thereby, it can be confirmed that the address setting has been performed for the terminal device 4 and the lighting equipment 5.

When transmitting the address signal, the transmitter 2 may transmit an operation signal indicating that the address is set. At this time, when the operation signal is input, the address setting unit 15 may store the address signal transmitted from the transmitter 2 in the storage unit 16 as its own address. It is not necessary to determine whether the signal is only an address signal, and the program can be simplified. Further, since the address setting unit 15 does not set the address unless an operation signal is input, erroneous setting of the address after the address setting can be prevented.

Then, when performing the lighting control, that is, the on / off control of the lighting load 19, the control signal is transmitted from the transmitter 2 toward the light receiving window 3 a of the receiver 3. The control signal received from the light receiving window 3a is input to the address determination unit 15 via the reception interface unit 13 of the terminal device 4.

The address determination unit 15 determines the input digital signal, and if the digital signal is a control signal, reads out its own address from the storage unit 16 and compares it with the address signal of the control signal. When the address signal of the control signal matches its own address, the control unit 17 is caused to perform an operation based on the control signal. The control unit 17 controls on / off of the relay 18 according to the dimming signal of the control signal.
Thereby, the lighting load 19 blinks and the lighting control is performed.

As described above, the address setting of the terminal 4 and the lighting control of the lighting load 19 can be performed using one transmitter 2. Since the transmitter 2 is used for lighting control of the lighting load 19, it can always be kept at hand.
Therefore, since there is little risk of powder loss or the like, it is possible to avoid any trouble at the time of maintenance work such as replacement or change of the terminal device 4, and it is not necessary to pay attention to management.

Next, a second embodiment of the present invention will be described.

FIG. 4 is a block diagram of a lighting control device showing a second embodiment of the present invention. The same parts as those in FIG. 1 or parts corresponding to the same parts are denoted by the same reference numerals and description thereof will be omitted.

The lighting control device 20 shown in FIG. 4 is the same as the lighting control device 1 shown in FIG. 1, except that a plurality of terminals 4, 4, 4,... Then, the receiver 3 and the lighting equipment 5 are respectively disposed in predetermined areas. The operating device 2 is configured to be able to transmit a control signal for controlling the lighting of the lighting load 19 or an address permission signal. Further, the main control device 6 can transmit a control signal for performing lighting control of the lighting load 19 or an address signal for setting an address of the terminal device 4.

After the installation of the lighting control device 20, the addresses of the terminals 4, 4, 4,... Have not been set. If the address is not set in the terminal device 4, data transmission from the main control device 6 cannot be performed. Therefore, addresses are set for the respective terminals 4, 4, 4,....

First, the terminal 4 for which an address is to be set is specified, and an address permission signal is transmitted from the operating device 2 to the light receiving window 3a of the receiver 3 connected to the terminal 4. The address signal received from the light receiving window 3a is converted into a digital signal by the receiver 3 and transmitted.
Is input to the address determination unit 15 via the reception interface unit 13.

The address determination section 15 determines the input digital signal, and if the digital signal is an address permission signal, shifts to an operation mode in which an address can be set. In this operation mode, the main controller 6 transmits an address signal. Then, the address determination unit 15 causes the storage unit 16 to store the address signal transmitted from the main control device 6 as its own address. Thereby, the address setting for the specified terminal device 4 is performed. Hereinafter, by sequentially transmitting the address permission signal from the transmitter 2 to the receiver 3 corresponding to the specified terminal 4 and transmitting the address signal from the main control device 6, the terminal 4, 4, 4,. Set the address.

When an address is set to the terminals 4, 4, 4,...
Nine lighting controls are possible. That is, when a control signal is transmitted from the transmitter 2 toward the light receiving window 3a of the receiver 3, the address determination unit 15 reads out its own address from the storage unit 16, and the address signal of the control signal is replaced with its own address. If they match, the control unit 17 is caused to perform an operation based on the control signal. The control unit 17 controls the on / off of the relay 18 according to the dimming signal of the control signal, and
Flashes.

Note that the address setting may be performed by transmitting an address signal from the transmitter 2 instead of the main controller 6.

As described above, since only the terminal 4 that has received the address permission signal transmitted from the transmitter 2 can set the address, the plurality of terminals 4, 4, 4, 4, 4 4, the address can be reliably set from the main controller 6 to the desired terminal 4. Also, since an address cannot be set unless an address permission signal is input to the terminal device 4,
It is possible to prevent erroneous setting of an address to another terminal device 4. The lighting of the lighting load 19 can be controlled using the transmitter 2.

[0050]

According to the first aspect of the present invention, address setting and illumination control can be performed by transmitting an address signal or a control signal to a receiver using one transmitter.

According to the second aspect of the present invention, the address setting section stores the address signal transmitted from the transmitter as its own address in the storage section when the operation signal is input. Signal determination can be simplified.

According to the third aspect of the present invention, only the terminal that has received the address permission signal transmitted from the transmitter can set the address. The address can be reliably set for a desired terminal.
