Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hotel lighting equipment remote control device.

Traditionally, in hotels, it was up to the guests to turn on and off the lighting fixtures in each area, and it was necessary to actually go to the room to check whether the lighting fixtures were on or off, which was especially difficult in hotels with a large number of rooms. Not only that, but the power loss caused by forgetting to turn it off is also enormous.

In view of the above-mentioned points, the present invention enables, by storing a room key in a key sorting department at the front desk, turning off the lighting fixtures in the room corresponding to this key and confirming that the lighting fixtures are turned off without having to go to each room. To provide a lighting equipment remote control device for a hotel which can prevent the lighting equipment from being forgotten to be turned off and save power.

The present invention will be explained in detail based on illustrated embodiments. 1 is a hotel room key, and this key 1 is stored in a key storage shelf 2a at the front desk. An opening/closing switch 13 consisting of a micro switch is disposed below the key organizing shelf 2a.
By storing the key 1 in the key 1, the arm 14 is pressed downward and the normally open contact 13a is closed.
When removed, it automatically returns to open the contact 13a. A key holding board 2b as shown in FIG. 3 is used instead of the key organizing shelf 2a as described above, and an opening/closing switch 1 consisting of a switch built in this key holding board 2b is provided.
By suspending the key 1 from 3, the normally open contact 13a
may be closed. This contact 13a and a two-circuit switching type control relay 15 are connected in series to a power source 9. The switching contacts 3a, 3b, which are opened and closed by the control relay 15, are connected in series to two diodes 4a, 4b, which are connected in antiparallel to each other.
A and 4b form an operation circuit 5. In addition, without using the control relay 15, by storing the key 1 in the key storage shelf 2a, the opening/closing contact 3 can be directly connected.
A two-circuit changeover switch that opens and closes a and 3b may be used. The operating circuit 5, the two diodes 6a and 6b connected in antiparallel to each other, and the excitation coil 8 of the polarized latching relay 7 are connected to a power source 9.
The diodes 6a, 6b are connected in series between the diodes 6a, 6b and the excitation coil 8.
Auxiliary contacts 7a of the relay 7 connected in series to
7b is inserted. The main contact 7c of the latching relay 7 is opened when a set current flows through the excitation coil 8, and remains open until a reset current flows. , 7b and the excitation coil 6 constitute a remote control relay circuit 16, which is installed in each room of the hotel. On the other hand, the main contact 7c
are connected in series to a control circuit 19 consisting of a series circuit of a remote control relay 17 and a remote control selector switch 18, and this control circuit 19 is connected to a power source 9 via a fuse 20. The remote control relay 17 includes two diodes 21a and 21b connected in antiparallel to each other, and a polarized latching relay 2.
2 auxiliary contacts 22a, 22b and the relay 22
It is constituted by a series circuit with the excitation coil 23 of
The remote control selector switch 18 also includes two diodes 24a and 24b connected in antiparallel to each other.
and a changeover switch 25 that is embedded in the wall of the room and can be operated manually.

When the room key 1 is stored in the key storage shelf 2a, the contact 13a of the open/close switch 13 is closed, the control relay 15 is energized, and the contact 3b is switched to the normally open side. Then, power supply 9 → excitation coil 8 → normally closed side auxiliary contact 7b → diode 6b → diode 4
The set current of the latching relay 7 flows to the terminal b, opening the normally closed main contact 7c, and at the same time switching to the normally open auxiliary contact 7a. Then, the set current stops flowing, but the main contact 7 is closed by the latching relay 7.
The open state of c is maintained. Next, when the key 1 is taken out from the key storage shelf 2a, the contact 1 of the open/close switch 13 is
3a automatically returns to open and control relay 15 becomes de-energized. Then, it switches to the normally closed contact 3a, and the power supply 9 → diode 4a → diode 6a →
The reset current of the latching relay 7 flows from the normally open side auxiliary contact 7a to the excitation coil 8, and the main contact 7c
At the same time, the auxiliary contact 7b is switched to the normally closed side, and the closed state of the main contact 7c is maintained. By the way, if the key 1 is taken out from the key storage shelf 2a and the main contact 7c is closed, if the changeover switch 25 of the remote control select switch 18 is set to the on side (the A side in FIG. 1), the diode 2
The setting current of the latching relay 22 flows through the latching relay 22 through the excitation coil 23, the main contact 22c of the relay 22 is closed, and the lighting fixture 11 is turned on. When the changeover switch 25 of the remote control selector switch 18 is set to the OFF side (C side in the figure), a reset current flows, the main contact 22c is opened, and the lighting fixture 11 is turned off. Furthermore, if the key 1 is stored in the key storage shelf 2a and the main contact 7c is in the open state, it goes without saying that the lighting fixture 11 cannot be controlled by the remote control selector switch 18. The control circuit 19
are provided in accordance with the number of lighting fixtures 11.

In addition, as shown in FIG. 4, a transmitter 27 is connected to the power lines 26a and 26b, and a control signal for the lighting fixture 11 is sent from the transmitter 27 by hanging the room key 1 from a switch 28 provided on the transmitter 27. and a receiver 29 connected to the power lines 26a, 26b.
The control signal transmitted via the power lines 26a, 26b may be received by the key 1 to open the main contact 30 that blinks the lighting fixture 11 in the room corresponding to the key 1. The operation of each control circuit 19 is the same as in the previous embodiment, so a description thereof will be omitted.

Thus, in the present invention, a switching contact is operated by storing a hotel room key in a key sorting department at the front desk, and two diodes are connected in series to this switching contact and are connected in antiparallel to each other. Forming an operating circuit, the operating circuit, two other diodes connected in antiparallel to each other, and an excitation coil of a polarized latching relay are connected in series to a power supply, and the auxiliary of the relay connected in series to each diode is connected in series to the power supply. A contact is inserted between the diode and the excitation coil, and the main contact of the relay turns on and off the lighting fixtures in the room corresponding to the key, so if you store the room key in the key collection department at the front desk, When the opening/closing contact is switched, a set current of the polarized latching relay flows through the opening/closing contact and the diode to the excitation coil, which opens the main contact that blinks the lighting fixture in the room corresponding to the key, and this open state is established. Therefore, the lighting fixtures in the room will be turned off, and therefore, just by checking the presence or absence of the key in the key shelf, you can confirm that the lighting fixture in the room corresponding to the key is turned off, unlike conventional methods. There is no need to go to each room to check on the lights, and even if a customer forgets to turn off a light fixture, they can simply store the key in the key collection department and the light fixture will be turned off, eliminating the loss of electricity due to forgetting to turn it off, making it more economical. Moreover, when the key is taken out from the key handling department, the opening/closing contact is switched and a reset current flows to the excitation coil via the opening/closing contact and the diode, which closes the main contact and maintains the closed state. , the lighting equipment can be turned on and off from within the room.
