Abstract

PROBLEM TO BE SOLVED: To provide a lighting system capable of performing address setting of luminaire without applying a load at the time of manufacture. SOLUTION: An instruction for address setting is given to set to an address setting mode and an address setting start signal is sent to all luminaires through a communication part 3a by an operation part 3d of a centralized monitoring panel 3. A control part 3b of the centralized monitoring panel 3 gives an instruction to fix a signal voltage level of a transmission wire 1 at a fixed level to the communication part 3a. Next, a control part 2e of the luminaire 2 receiving the address setting start signal operates a constant current load 2b to consume a fixed current due to a voltage between a pair of transmission wires 1 and 1. At this time, voltages of signals on the transmission wire 1 in each luminaire 2 differ due to the effect of impedance component of transmission wire 1 itself and a difference in connection positions of the transmission wires 1. Lastly, each luminaire 2 detects a signal voltage between the transmission wires 1 and 1 and stores the information as an address value in a memory part 2d.

In most cases, an original number (such as a serial number) is stored in a dip switch or a non-volatile memory in a terminal manufacturing process. An operation such as input is required. In addition, when those terminals are actually installed, it is difficult to control which terminal stores which original number, and the original number is written so that it can be seen even after installation on the terminal.

The lighting fixture 2 includes a communication unit 2a, a constant current load 2b as a constant current consuming unit, a lamp load 2c, a storage unit 2d, and a control unit 2e. Here, the communication unit 2a receives a signal from the transmission line 1 or transmits the signal to another lighting apparatus 2 via the transmission line 1,
The constant current load 2b consumes a certain current due to the voltage of the transmission line 1, the storage unit 2d stores various information, and the control unit 2e operates from a remote controller (not shown). And the signal from the communication section 2a to control the lamp load 2c, and refer to or rewrite the contents of the storage section 2d.

The centralized monitoring panel 3 includes a communication unit 3a and a control unit 3
b, a storage unit 3c, and an operation unit 3d. Here, the communication unit 3a receives a signal from the transmission line 1 or transmits a signal to the lighting apparatus 2 via the transmission line 1, and the control unit 3b uses the signal from the communication unit 3a to store the signal in the storage unit 3c. And outputs a signal to the communication unit 3a based on the operation of the operation unit 3d.
The storage unit 3c stores various information,
The operation unit 3d performs various settings and operation instructions.

The luminaire 2 and the centralized monitoring panel 3 have power supplies 2f and 3e for driving the respective functions.

As shown in FIG. 4, the constant current load 2b comprises an FET 4, resistors R1 and R2, and a diode D, and the collector terminal of the FET 4 is connected to one of the pair of transmission lines 1. The emitter terminal is connected to the other transmission line 1 via the resistor R1. A resistor R2 is connected to the base terminal, and a diode D is connected between the base terminal and the emitter terminal of the FET 4 via a resistor R1.

Here, the resistor R2 is connected to the base terminal of the FET4.
When a signal is input through the FET 4, the FET 4 is turned on, and current is consumed by the resistor R1.

The operation of the lighting apparatus according to the present embodiment when setting an address will be described below with reference to FIG. First, an instruction is made to perform an address setting by the operation unit 3d of the centralized monitoring panel 3, and an address setting mode is set. Subsequently, the centralized monitoring panel 3 transmits an address setting start signal to all the lighting devices 2 via the communication unit 3a by the above operation. After transmitting the address setting start signal, the control unit 3b of the centralized monitoring panel 3 sends the signal voltage level of the transmission line 1 to the communication unit 3a at a constant level (10 V in this embodiment).
Instruct to fix with.

Next, upon receiving the address setting start signal, the control unit 2e of the lighting fixture 2 operates the constant current load 2b and
A constant current (10 mA in this embodiment) is consumed by the voltage between the pair of transmission lines 1. At that time, due to the influence of the impedance component of the transmission line 1 itself, the difference in the connection position of the transmission line 1 (the distance on the transmission line 1 from the central monitoring panel 3) causes the signal of the signal on the transmission line 1 in each lighting fixture 2 to change. The voltage is different.

More specifically, when each lighting fixture 2 is operating in the address setting mode, a current of 10 mA is consumed by the constant current load 2b. here,
It is assumed that the voltage of the signal output from the centralized monitoring panel 3 is a constant voltage V, the transmission line 1 is a finite length cable, and an impedance component Z depending on the length exists.

For the sake of simplicity, consider the case where each lighting fixture 2 and the centralized monitoring panel 3 are connected at regular intervals, and a voltage drop occurs at the impedance Z of the cable due to the current consumption of each lighting fixture 2, The voltage between both ends of the cable in the lighting fixture 2 differs by a voltage drop due to the cable impedance between the lighting fixtures 2.

In the case shown in FIG. 5, V1 = V- (0.01 + 0.01) Z- (0.01 + 0.01) Z V2 = V- (0.01 + 0.01) Z-0.01Z-0.01Z- (0.01 + 0.01) Z, and a difference of 2 × 0.01Z occurs between V1 and V2.

Finally, each lighting fixture 2 detects a signal voltage between the transmission lines 1 and stores the information as an address value in the storage unit 2d.

Therefore, in this embodiment, the address is not stored in each lighting fixture 2 at the time of manufacturing, and
Without the trouble of setting each address after construction,
Unique address information can be given to each lighting fixture 2 connected on the same transmission line 1 almost instantaneously.

In the present embodiment, the constant current load 2b is provided in each of the lighting fixtures 2. However, when the transmission line 1 is a long distance or the like, even a small current due to the impedance of the signal receiving circuit in the communication unit 2a. Similar effects can be obtained.

Embodiment 2 = FIG. 6 is a block diagram showing a lighting fixture 2 according to another embodiment of the present invention, and FIG. 7 is an operation explanatory diagram of a lighting device according to this embodiment. The lighting fixture 2 according to the present embodiment includes:
Embodiment 1 is a configuration in which a remote control receiving unit 2g is added to the lighting fixture 2 illustrated in FIG. 2 as Embodiment 1. Here, the remote control receiving section 2g receives a remote control signal.

In the first embodiment, the centralized monitoring panel 3 exists, and the address information is obtained by the signal from the centralized monitoring panel 3. However, in the present embodiment, the centralized monitoring panel 3 does not exist, and A distributed control method is used in which the lighting fixture 2 operates according to each determination.

Hereinafter, the operation of this embodiment will be described with reference to FIG. First, a remote control signal transmitter (not shown) sends an address setting start signal to a desired lighting fixture 2.
Send to

The lighting equipment 2 which has received the address setting start signal from the remote control signal transmitter broadcasts a signal indicating the same contents to all the other lighting equipment 2 via the transmission line 1 via the communication unit 2a. Send.

The luminaire 2 which has received the signal from the remote control signal transmitter itself becomes a reference appliance, and transmits a signal from the communication unit 2a to a fixed voltage level (10 in this embodiment).
The output is fixed at V), and the other luminaires 2 operate in the address setting mode.

Next, the control unit 2e of the lighting fixture 2 which has received the signal from the reference fixture operates the constant current load 2b, and the constant current (10 mA in the present embodiment) by the voltage between the pair of transmission lines 1. To consume. At this time, due to the influence of the impedance component of the transmission line 1 itself, the voltage of the signal on the transmission line 1 in each lighting fixture 2 changes due to the difference in the connection position of the transmission line 1 (distance on the transmission line 1 from the reference device). different.

Finally, each lighting fixture 2 detects a signal voltage between the transmission lines 1 and stores the information as an address value in the storage unit 2d.

Therefore, in the present embodiment, the same effect as that of the first embodiment can be obtained by using the predetermined lighting fixture 2 as a reference fixture and playing the role of the centralized monitoring panel 3. The address setting can be easily performed even in a lighting device using a distributed control method without the panel 3.

= Embodiment 3 = FIG. 8 is an operation explanatory view of a lighting device according to another embodiment of the present invention. In the present embodiment, a description will be given of a case where there is a lighting fixture 2 having the same address information obtained from the voltage value of the signal line, which may occur when the wiring form of the transmission line 1 is branched in the first embodiment. I do.

When the address setting described in the first and second embodiments is performed with the connection configuration as shown in FIG.
Therefore, in the lighting fixtures 2 connected by the transmission lines 1 of exactly the same length, there is a possibility that the signal voltage in each lighting fixture 2 becomes the same (actually, variations in circuit elements, variations in transmission line cables, etc. are considered). Is unlikely).

Therefore, in this embodiment, after each lighting fixture 2 reads the voltage value in the address setting mode, the centralized monitoring panel 3 monitors the read voltage value of all the lighting fixtures 2 in a centralized manner. Order to send to board 3. At this time, voltage values are sent from all the lighting fixtures 2,
If the lighting fixtures 2 having the same voltage value exist, a signal indicating the same voltage value reaches the centralized monitoring panel 3.

When receiving the signal indicating the same voltage value, the centralized monitoring panel 3 transmits a signal indicating that the voltage values are duplicated to the luminaire 2 having the same voltage value.

The luminaire 2 receiving the signal adds a random element to the read voltage value and sets it as its own voltage value again.

The random element may be a voltage value equal to or less than the voltage drop due to a cable of that length, if the minimum value of the wiring length between the appliances is clear, or a read voltage value. Instead, an address area to be used only in the case of overlapping is provided in advance, and lighting fixtures 2 having overlapping voltage values are randomly selected from the address areas, or various elements can be considered.

Therefore, in the present embodiment, even if the voltage values of the lighting fixtures 2 become the same, simple address setting can be performed so that the same address is automatically avoided without duplication of the address.

In this embodiment, the first embodiment
In the above, the case where the voltage values of the lighting equipment 2 overlap was described, but the present invention can also be applied to the case of Embodiment 2, in which case the lighting equipment 2 as the reference equipment plays the role of the centralized monitoring panel 3. become.

Embodiment 4 = FIG. 9 is an explanatory view of the operation of a lighting device according to another embodiment of the present invention. In the present embodiment, as shown in Embodiment 2, in a distributed control type lighting device without a centralized monitoring panel 3, a lighting device connected from a lighting device 2 serving as a reference device by a transmission line 1 of exactly the same length. 2, the case where the signal voltage becomes the same will be described. In the present embodiment, as shown in the third embodiment, the same effects as in the third embodiment can be obtained by the lighting fixture 2 serving as the reference fixture serving as the centralized monitoring panel 3.

In all the embodiments described above,
Although the read voltage value was used as the address information as it is, the present invention is not limited to this. The logical address based on the voltage value is assigned to the centralized monitoring panel 3 or the lighting fixture 2 serving as a reference fixture. You may do it.

For example, the lighting fixture 2 that has read the voltage value
Transmits the voltage value to the centralized monitoring panel 3 (or the lighting fixture 2 as the reference fixture). Then, the centralized monitoring panel 3 (or the lighting fixture 2 as the reference fixture) that has received the voltage values from all the lighting fixtures 2 rearranges the received voltage values in order of magnitude, and attaches numbers in ascending order. Lighting equipment 2 corresponding to each voltage value
Then, the numbers associated in order of magnitude are transmitted as logical addresses.

By doing so, a continuous address can be given in the lighting device, and the management (for example, the number of lighting devices) of the lighting fixtures 2 can be easily performed.

Further, since it is difficult to know which value exists as the voltage value, when an operation instruction is given from the outside, the logical address value is larger than the discontinuous voltage value. But easy to use.
