Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for lighting equipment in a building that controls on/off of lighting equipment in a large building such as a building individually or by radio waves. More specifically, the purpose is to greatly simplify indoor wiring work by controlling on/off of a large number of lighting equipment using radio waves.

Another purpose is to minimize wasteful power consumption by controlling a large number of lighting equipment in groups according to appropriate guidelines, rather than controlling them all at once with a single power switch. It's about doing.

Another object of the present invention is to make it possible to easily change the installation locations of switches in response to changes in partitions, and to easily classify lighting equipment into groups.

[Conventional technology]

A large number of lighting fixtures are arranged inside a large building such as a building, and indoor wiring for this large number of lighting fixtures is extremely complicated.

For example, most lighting fixtures are fixed to the ceiling in a fixed array, and the power lines connected to each lighting fixture are routed through the wall of the building, and switches for controlling the lighting fixtures are fixed to this wall section. There is.

[Problem that the invention seeks to solve]

In this way, when wiring for lighting equipment, the switch must be installed in a place where people can reach, so the power line must be routed to the required point, and as a result, the indoor wiring is simply a large number of wires. This is much more complicated than just connecting to a lighting fixture.

Moreover, in reality, emergency wiring is required in addition to the power supply line, including the ground wire, and switches need to be installed in many locations rather than just one location. Therefore, indoor wiring becomes much more complicated and construction costs become enormous.

Particularly in modern buildings, after the basic work including indoor wiring work is completed, necessary indoor work is done by appropriately partitioning each floor, but the layout of the partitions for this indoor work is as described above. Since it is completely impossible to predict the situation at the time of basic construction, it is difficult to say that the arrangement of switches corresponding to the layout of this indoor construction is convenient.

For this reason, usually after indoor construction, following this layout, wiring is extended from the switch part during basic construction to the floor or ceiling, and the switch is installed at the desired location, or individual lighting fixed to the ceiling is wired. A switch was attached to the fixture, a long string was hung from it, and the switch was controlled individually for each lighting fixture.

As described above, conventional on/off control of lighting equipment not only requires enormous construction costs due to excessively complicated indoor wiring, but also has extremely poor adaptability to changes in indoor layouts, that is, changes in partitions, and is time consuming. However, there were various drawbacks and dissatisfied points, such as the fact that the string for the switch significantly spoiled the aesthetics of the interior.

The present invention was devised to eliminate all of the above-mentioned conventional drawbacks and dissatisfied points.The present invention has been devised to solve all of the above-mentioned conventional drawbacks and dissatisfied points. This receiver is configured to be operated by radio waves using a control panel installed at an appropriate location such as on a wall or on a desk.

[Means for solving problems]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A control device according to the present invention will be described below with reference to drawings showing an embodiment of the present invention.

The means according to the present invention is a control device that uses radio waves to control on/off of a large number of lighting fixtures S installed on one floor in a building, in which a desired number of groups S -1, S-2... Each divided group S-1, S-2...
installing a receiver 3 that controls the connection and disconnection of the power line 4 to the power line 4 by receiving an on signal and an off signal, which are radio waves of different frequencies; It has an on transmitting section 10 and an off transmitting section 11 that transmit an on signal and an off signal, and is composed of a self-returning type switch that self-returns to a neutral point.

-2... A hand-held control panel 2 having the same structure and having a battery as a power source is placed at a desired location such as on a desk near the corresponding group S-X.

[Effect]

The receiver 3 attached to each group S-1, S-2, etc. of the lighting equipment S has almost the same structure as a so-called receiver, and receives radio waves of different frequencies from the control panel 1 or 2. By receiving the signal or OFF signal, connection/cutoff to the power line 4 of the group S-X to which the receiver 3 is attached is achieved and controlled, and the frequency of the ON signal and OFF signal for any receiver 3 is controlled. are different, and the frequencies of the ON signals and OFF signals for each receiver 3 are also completely different.
will not operate unless there is a signal from the transmitter 1-X of the corresponding collective control panel 1 or a signal from the corresponding local control panel 2.

A collective control panel 1 placed and fixed at a suitable location on a wall etc. has the same number of transmitters 1-1, 1-2... as receivers 3 attached to each group S-1, S-2...
are provided in correspondence to each of the receivers 3, and the transmitters 1-1, 1-2, . Since the switch is operated by the control unit 12 which is a self-resetting type switch that automatically returns to
When controlling on/off of the transmitter 1-X corresponding to the desired group S-X, the user
1. Operate the control unit 12 of.

In contrast to this collective control panel 1, the local control panel 2 is
Each transmitter 1-X in the collective control panel 1 is placed close to the corresponding group S-X in a guest room or on a desk that is divided into small rooms corresponding to the individual groups S-1, S-2... It has the same configuration as the transmitter, with a transmitting antenna attached, and the power source is a battery so that it can be installed anywhere.

On/off control of the lighting equipment S by the collective control panel 1 is performed by the control unit 12 of each transmitter 1-1, 1-2...
By sequentially operating the lighting fixtures S, each group S-1, S-2... is controlled on/off separately.

The on/off control of each group S-1, S-2... is not limited to this collective control panel 1, but is provided corresponding to each group S-1, S-2... You can also use the hand control panel 2.

That is, both control panels 1 and 2 simply transmit an on signal or an off signal that is a signal for setting the state of the receiver 3, and each receiver 3 transmits this on signal or off signal. Since the receiver body 3 self-maintains the state set by the reception of
Regardless of whether the received signal is transmitted from the collective control panel 1 or the local control panel 2, it is sufficient to follow the received signal.

In this way, the on/off control of each group S-1, S-2... can be achieved individually and independently on both control panels 1 and 2, so the collective control panel 1
A large number of lighting fixtures S on one floor are grouped into groups S-1, S-2...
...can be controlled on and off at each time, and
On/off control of only any group S-X can be achieved using the local control panel 2.

In addition, since the switching operation in each receiver 3 is performed by an on signal or an off signal from the control panels 1 and 2, the installation location of each receiver 3 is not specified, and for example, each group S -X
Since it can be freely installed at a location where it is easy to connect to, it is difficult to change the partition due to the presence of the part for achieving off-on/off control of each group S-X, that is, the receiver 3. You can eliminate the inconvenience.

Furthermore, changing the grouping of a large number of lighting fixtures S can be easily achieved by simply changing the connection between each lighting fixture S and the connection with the receiver 3. Changes in grouping can also be easily accomplished.

〔Example〕

In the illustrated embodiment (see FIG. 3), the collective control panel 1 includes transmitters 1-
1, 1-2, . . . are connected in parallel to one transmitter 13, and an on signal or an off signal is transmitted from an antenna 14 connected to this transmitter 13. Control unit 1 in each transmitter 1-X
2 has a switch part for operating the ON transmitter 10 and a switch part for operating the OFF transmitter 11, and this switch part automatically returns to the neutral point when the touch switch or push button switch is in the released state. It has a structure that allows it to recover.

This collective control panel 1 has a desired number of transmitters 1-X.
are connected in parallel to one transmitter 13, so the transmission signal from the collective control panel 1 is transmitted sequentially from each transmitter 1-X, and simultaneously connected to the two transmitters 1-X. It is never sent from.

The receiver 3 (see Figure 4) is connected to the control panel 1 or 2.
A receiver 30 having an antenna 36 receives a signal from the receiver 30, filters the received signal, and discriminates whether an on signal is an off signal using an on signal selector 31 and an off signal selector 32.
The power drive 33 is driven in accordance with the selection signals 1 and 32 to activate a relay 34 having a self-holding function of a power switch 35 that connects and disconnects the lighting device S to the power line 4.

The reception operation in the receiver 3 is based on the fact that there are various electrical equipment indoors, and these electrical equipment generate noise in the form of radio waves, and the lighting equipment S itself generates noise when operating. Therefore, in order to prevent malfunctions caused by these noises, a filter circuit is installed, and
The signals from the control panels 1 and 2 are assumed to last for a predetermined period of time, for example, about 1 second, and are integrated by an integrating circuit, and are turned on or off when they reach a predetermined level.

On the other hand, in order to prevent the signals from control panels 1 and 2 from causing electrical disturbances to other electrical equipment, the output signals from control panels 1 and 2 are set to relatively weak values. ing. In this way, the output signals from control panels 1 and 2 are weak, but in actual use, the output signals from control panels 1 and 2 are
Since the distance between 2 and the receiver 3 is at most 20 to 30 m on the same floor, the receiver 3 can be operated sufficiently even if the output of the transmission signal is weak.

The power supply for the collective control panel 1 uses a dedicated power line,
In addition, if the collective control panel 1 on each floor uses the same power line as a power source, the power supply line for controlling the collective control panel 1 can be used to predetermined on/off control of the lighting fixtures S of the entire building. It can be centrally controlled at any location.

That is, for example, a shift register operated by a predetermined pulse is provided between a dedicated power line and each collective control panel 1 through a dedicated power line from the central control room, and the output from this shift register By activating each transmitter 1-X of the collective control panel 1 in sequence, the lighting fixtures S of the entire building can be controlled on and off for each floor from the central control room.

Therefore, it is possible to prevent forgetting to turn off the lighting equipment S after the end of work, thereby eliminating wasteful consumption of power, and it is also possible to save the effort of a person to go to each floor and turn on the switch at the beginning of work.

Centralized control of the lighting equipment S for the entire building is possible because the collective control panel 1 and local control panel 2 installed on each floor are turned on and off for a certain period of time (generally about 1 second is good). This is because both the control panels 1 and 2 and the receiver 3 are in a neutral state after the on/off control is performed.

In addition, when performing centralized control in this way, if the collective control panel 1 cannot be placed close to the power supply line as a dedicated control circuit, use a device with the same configuration as this collective control panel 1 as a dedicated power source. It may be attached to a location where the wire is arranged, thereby providing centralized control.

〔Effect of the invention〕

As is clear from the above description, the device according to the present invention can turn on a large number of lighting fixtures simply by using radio waves.
In addition to off-control, the power switch in the receiver is self-holding, the control units in both control panels are self-resetting switches, and the on and off signals in each group are set to radio waves with completely different frequencies. This not only allows for individual on/off control of each group, but also facilitates centralized control of the entire building, and greatly simplifies installation and modification of indoor wiring. This makes it easy to change the partitions on the floor, and allows the partitions to be changed freely.

Furthermore, if you wish to control the lighting fixtures individually, you can do so from the handheld control panel, so there is no need to provide a switch string or the like to the lighting fixtures, thereby improving the aesthetics of the room.

Furthermore, it prevents people from forgetting to turn off lighting equipment, and also prevents unnecessary lighting equipment from being turned on, thereby eliminating wasted power consumption.
It exhibits many excellent effects, including a high energy saving effect.
