For this reason, the illumination lamp corresponding to the receiving means which has newly received the code signal is automatically turned on as the visitor moves, and the illumination lamp corresponding to the receiving means which has stopped receiving the code signal is automatically turned off. To do. Therefore, it is not necessary to manually operate the switch of the illumination lamp, and the illumination pattern is changed to an appropriate illumination pattern according to the movement of the visitors, and only the place where illumination is required is illuminated.
The waste of lighting power can be avoided.

〔Example〕

FIG. 1 shows an intelligent building 10 to which an embodiment of the present invention is applied.

In this intelligent building 10, the number of visitors is 2nd in advance.
It is obligatory to have the ID card 12 shown in the figure and enter the building. The ID card 12 is formed of a thin plate material of synthetic resin as an example, and a photograph 14 of the visitor is attached to the surface of the ID card 12, and a display column 16 corresponding to the photograph 14 such as belonging name and the like is provided. Also this ID card 12
A clip 18 is provided on the back surface of the device so that the ID card 12 can be attached to a chest pocket or the like.

The ID card 12 incorporates the circuit shown in FIG.
Power is supplied from 2 to all circuits such as the arithmetic unit 24.
In 4, the signal from the receiving unit 26 is calculated and it is determined whether or not the signal is a calling signal for the ID card 12 of its own. When necessary, the notifying unit 28 and the transmitting unit 30 are activated to notify the outside and Calls are being made.

In addition, in the ID card 12, the main circuit of the arithmetic unit 24 is not energized at all times, and only when the receiving unit 26 receives a call signal from the outside, the power supply switching unit 20.
Is activated so that the main circuit of the arithmetic unit 24 is activated by the power source 22, the life of the power source unit 22 can be extended.

As an example, this power supply unit 22 can be used as a thin card-shaped battery having a structure in which manganese dioxide powder is applied to one of two conductive plastic films and zinc powder is applied to the other, and a non-woven fabric is sandwiched between them. In addition, the calculation unit 2
4, the reception unit 26, the notification unit 28, and the transmission unit 30 may be, for example, an IC card in which an IC device is built in a thin plastic card.

The transmitting unit 30 can transmit a signal for identifying itself, such as a different frequency, for each of the ID cards 12 manufactured, and the notifying unit 28 responds to different types of received signals received by the receiving unit 26. Different types of notification signals can be emitted. For example, in the case of transmitting a call signal to a person who has an ID card 12, a call signal to a specific room, a signal to the in-house telephone, etc., such as a tone signal, a frequency, a signal period, etc. The output signal to the speaker may be controlled so as to be changed and emitted.

FIG. 1 shows a case in which the automatic control device for an illuminating lamp according to the present invention is applied to the above-mentioned central control device for a building, and the central control device for a building receives the code signal from the ID card 12 as described above and enters the building. This is a comprehensive centralized management system that grasps the locations of people who enter the building and the location of the people who enter the building, and automatically controls elevator operation management, room air-conditioning control, etc. based on the results of computer calculations.

First, the centralized management system will be described.

Antes 40A, 40B, etc. are installed in the halls, such as the corridor and the ceiling of the room in the example of FIG. 1 where centralized control is to be performed, and the code transmitted from the ID card 12 by the arrival of the ID card holder. The signals are these antennas 40
The radio signals (TRT) 42A, 42B ... Are operated by the code signals received by the A, 40B, ..., And the code signals are transmitted by the local radio control device (LRC) 44.
A, 44B, ..., Local Area Network (LA
N) 46 via the central radio controller (C
CRC4 transmitted to RC) 48 and received the code signal
8 sends this code signal to the building management processor (GP) 50.

In the GP 50, data processing such as the transmission position of the code signal and the number of ID card holders is executed from this code signal, and the data is displayed 52 and the printer 5 as required.
4, the data is displayed and the data is printed out.

Further, in the GP 50, for example, the air-conditioning state at a code signal transmission part (a specific area such as a conference room or an office) is automatically controlled based on a calculation result based on the code signal.

Therefore, the air conditioning control data sent from GP50 is C
It is supplied to the building control remote station (SRS) 56C via the RC 48 and the LAN 46, and the temperature, humidity, air flow rate, etc. of the indoor air supply of the corresponding air conditioner 60 is automatically controlled.

In addition, 62 is a distributed processing processor (DDP), 64 is an electronic exchange (EPBX), and GP is used in an emergency.
EPBX64 based on 50 or DDP62 command
Is controlled so that a specific telephone line can be secured, for example.

The automatic control device for an illumination lamp according to the present invention functions as a part of this centralized management system.

In the embodiment shown in FIG. 1, the illumination lights to be controlled are the illumination lights LA and LB provided in the corridor and the office, respectively.
In the case of LC, where the corridor is long, the plurality of lighting lamps LA to LC installed in this corridor are divided into a plurality of areas, two areas A and B in the figure, and inside each area A and B. The lighting of each is controlled independently.

When the control areas are divided into a plurality of areas as described above, an automatic control system for the illumination lamp is provided corresponding to each control area.

Now, the antennas 4 installed on the ceilings of the respective control areas A and B and the office (hereinafter, the office is also referred to as the control area) C
The code signal transmitted from the ID card 12 is received at 0A to 40C.

When the antennas 40A to 40C in the specific area receive the code signal, the TRTs 42A to 42C connected to the antennas 40A to 40C transmit the GP50 and the SRSs 56A to 56C via the LAN 46, and the SRS56A. 56C, based on the reception of this code signal, the illumination lights of the specific areas A to C to be controlled by the SRSs 56A to 56C are controlled to be turned on.

When the code signal disappears, the SRSs 56A to 56C automatically turn off the illumination lamp after a predetermined time has elapsed. Therefore, since GP50 is not required for the illumination lamp control, TRT42A to 42C and SRS56A to 56 are used.
C has a closed control loop configuration.

In each control area A to C, the above-mentioned SRS 56A to 56
C are provided respectively, and closed control is performed in each of the control areas A to C.

The above-mentioned antennas 40A to 40C are selected to have directional characteristics that are sensitive only to the code signals transmitted from within the area where the antennas are installed, and therefore, depending on the code signal transmitted from outside the area, The SRS never responds.

FIG. 4 is a flow chart showing an example of the control operation of the automatic control device shown in FIG.

When the control program starts and the antenna in the specific area receives the code signal (step a), the code signal is transmitted to SRS56A to 56C (step b), and the illumination lamp is turned on by the control signal from SRS56A to 56C. Lighting is controlled (step c).

Then, in step d, the presence or absence of the code signal is checked. If the code signal is being received, step c
Then, the lighting control state of the illumination lamp is continued.

However, when the disappearance of the code signal is confirmed in step d, the process proceeds to step e, and after a predetermined time has elapsed from the code signal disappearance timing, the illumination lamp is controlled to be in the off state.

The code signal disappears when the holder of the ID card leaves the specific control area.

Therefore, in the case of FIG. 1, when the passengers in the elevator get off and start walking in the corridor, the illumination light LA in the control area A is first turned on, and when the user walks near the control area B, the control system of the control area B is changed. Operates and lights L in control area B
B is turned on, and instead, the illumination lamp LA in the control area A is turned off.

When a person enters the control area C, the indoor illumination lamp LC in the control area C is turned on, and the illumination lamp LB in the control area B is turned on.
Turns off.

When the visitor exits, the illumination lights are turned on and off in the reverse order of the above.

It should be noted that in a place such as a corridor, the spare light is always on, but in order to ensure the minimum illuminance, about one of the lighting lights may be excluded from the control target and may be always on. .

When the control operation described above is executed based on the command from the GP 50, data indicating a specific area is added to the code signal transmitted from the TRTs 42A to 42C, and G
In P50, a control command may be selectively transmitted to the corresponding SRS 56A to 56C.

〔The invention's effect〕

In the automatic control device for the illumination lamp according to the present invention described above,
The ID card that automatically transmits the code signal is attached to the visitors, and the illumination lamp corresponding to the receiving means receiving the code signal is turned on and the illumination lamp corresponding to the receiving means not receiving the code signal is turned off. Since it was controlled so that it can be selectively illuminated only when it is needed, only a necessary part can be significantly reduced in lighting power compared to the conventional,
Energy saving can be achieved.

Of course, since it can be turned on and off automatically, it is possible to reliably avoid forgetting to turn off the lighting.
