DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control device for monitoring and controlling a plurality of lighting loads for each group.

[0002]

2. Description of the Related Art Hitherto, as a lighting monitoring control system, there has been proposed a configuration in which a plurality of lighting loads and a plurality of operation switches are connected to a lighting control device via a transmission line. In this type of lighting control system, an address is individually set for each lighting load and each operation switch, and by using the address, the operation information of each operation switch is individually identified, and for the lighting load, Lit (on)
・ Light-off (off) instructions can be given individually. Therefore, if the relation of which lighting load is turned on in response to the control input from which operation switch is registered in the lighting control device in advance, the control input from each operation switch is registered in the lighting control device in advance. It is also possible to perform group control for collectively controlling a plurality of lighting loads for each group according to the set contents. That is, when there is a control input from the operation switch via the transmission line, the lighting control device can perform control such that the lighting loads of the group corresponding to the operation switch are collectively turned on / off. It is.

[0003] More specifically, the above-described illumination monitoring and control system has a configuration as shown in FIG. 5, for example. The lighting control device 10 'includes a plurality of operation terminals 4 for monitoring the operation of the operation switch SW, a plurality of control terminals 3 for controlling the lighting load L, and the like, a two-wire signal line Ls.
Connected via Operation terminal 4, control terminal 3
, An individual address is set, and the lighting control device 10 ′ individually recognizes the operation terminal 4 and the control terminal 3 using the addresses.

[0006] The illumination control device 10 ′ transmits a transmission signal Vs having a format as shown in FIGS. 6A and 6B to the transmission line Ls. That is, the transmission signal Vs includes a start pulse ST indicating the start of signal transmission, mode data MD indicating a signal mode, address data AD, control data CD for controlling a lighting load L, checksum data CS for detecting a transmission error, This is a bipolar (± 24V) time-division multiplex signal composed of a signal return period WT for setting a return period of a return data signal from the control terminal 3 or the operation terminal 4, and data is transmitted by pulse width modulation. It has become so.

In each of the control terminals 3 and the operation terminals 4, when the address data AD transmitted by the transmission signal Vs received via the transmission line Ls matches the preset own address, the transmission is performed. Control data C of signal Vs
D and the signal return period W of the transmission signal Vs.
The return data is synchronized with the current mode signal (transmission line Ls
Are short-circuited through an appropriate low impedance and sent out as a signal.

[0006] The illumination control device 10 'is provided with a dummy signal transmitting means and an interrupt processing means. The dummy signal transmitting means constantly transmits a dummy transmission signal in which the mode data MD is set to the dummy mode. When the interrupt signal Vi as shown in FIG. 6C is returned, the interrupt processing means detects the operation terminal 4 that has generated the interrupt signal Vi, and accesses the operation terminal 4 to access the operation terminal 4. Reply data is returned from the operation terminal device 4 that has generated the interrupt signal Vi. That is, the dummy transmission signal is normally transmitted to the transmission line Ls by the dummy signal transmission means, and the interrupt signal Vi generated from the operation terminal 4 in accordance with the operation of the operation switch SW is synchronized with the start pulse signal ST of the dummy transmission signal. Then, from the illumination control device 10 ', a transmission signal Vs in which the mode data signal MD is set to the address confirmation mode is transmitted to the transmission line Ls by the interrupt processing means. Each operation terminal 4 sets an interrupt flag for requesting an interrupt when an interrupt signal Vi is generated, and in the operation terminal 4 for which the interrupt flag is set, the mode data signal MD indicates the transmission signal Vs in the address confirmation mode. Is received, the address set in the operation terminal 4 is returned as return data in synchronization with the signal return period WT of the transmission signal Vs. In this way, the illumination control device 10 'can acquire the address of the operation terminal 4 that has generated the interrupt signal Vi.

In the lighting control device 10 ', the interrupt signal V
When the address of the operation terminal 4 that generated i is obtained,
In addition to generating control data to be transmitted to the control terminal 3 to which the lighting load L whose correspondence with the operation switch SW is set in advance is transmitted, a transmission signal Vs including the control data CD is transmitted to the transmission line Ls, The control data CD is transmitted to the corresponding control terminal 3 to control the lighting load L.

Each of the operation terminals 4 has a status display section composed of a light emitting element such as a light emitting diode which is turned on and off in response to turning on and off of the lighting load L in response to operation of the operation switch SW. On the other hand, when the operation of the operation switch SW is performed, the lighting control device 10 ′ controls the respective lighting loads L of the group associated with the operated operation switch SW collectively, and after the control, controls the lighting load L of the group. The state of each lighting load L is monitored, and if all the lighting loads L of the group are in the on state, the light emitting element is turned on to turn on the state display section.
Is off, the light emitting element is turned off so that the state display section is turned off. That is, when the ON operation is performed by the operation switch SW and all the lighting loads L associated with the operation switch SW are turned on, the state display unit is turned on, and the off operation by the operation switch SW is performed. When all lighting loads L associated with the operation switch SW are turned off, the state display unit is turned off.

[0009]

By the way, the lighting load L
Is performed, for example, when the operation switch SW is operated (ON operation) when all the lighting loads L of the group to be controlled are in the OFF state and the corresponding state display unit is in the OFF display. In some cases, there is a failed lighting load L that is not turned on but remains off.
However, in the above-described conventional lighting control device 10 ′, when the lighting load L in the on state and the lighting load L in the off state are mixed in the group, the display before the operation of the operation switch SW is displayed on the state display unit. Is to be maintained.
That is, even though the lighting load L which is not turned on by the operation switch SW is turned on and the non-failed lighting load L is turned on, the status display section is displayed as off, and even if the operation button of the operation switch SW is pressed thereafter, the failure occurs. Lighting load L not
There was a problem that batch control was not possible.

The present invention has been made in view of the above circumstances, and an object of the present invention is to control a plurality of lighting loads in a group in accordance with the operation of an operation switch. It is an object of the present invention to provide a lighting control device that can control the remaining lighting load even if it exists.

[0011]

In order to achieve the above object, the present invention provides a plurality of lighting loads, an operation switch for collectively turning on and off the lighting loads in a group, and a lighting in the group. An illumination control device connected via a transmission line to an operation terminal having a status display unit for performing on-display / off-display according to an on-state / off-state of a load, and detects an operation of an operation switch. Switch operation detecting means, and lighting load control means for controlling the lighting load in the group based on the output of the switch operation detecting means,
A collation unit that determines whether to turn on or off the status display unit after collectively controlling the lighting loads in the group based on the operation of the operation switch, and a status display based on the determination result of the collation unit. Status indicator lamp changing means for changing the display of the unit, the collation means, if all the lighting loads of the group are in the on state, the state display unit to the on display, if all the lighting loads are in the off state Off display,
If the lighting load in the on state and the lighting load in the off state are mixed, it is determined that the state display section is changed from the display before the operation is performed, and the operation switch is operated. Then, since the display of the status display section always changes, even if there is an uncontrollable lighting load in the group associated with the operation switch, it is determined whether the operation switch has been turned on or off. Even if there is an uncontrollable lighting load in the group, the remaining lighting loads can be collectively turned on / off by operating the operation switch even if the uncontrollable lighting load exists in the group.
