Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an indoor power supply control system in a hotel or the like, which is applied to control the power supply to electric appliances in each room in a facility such as a hotel.

For example, each guest room in a hotel is equipped with various electrical appliances such as lighting equipment, air conditioners, and televisions. Since these electrical appliances can be used by passengers at their discretion, they are often left in the operating state when checking out or temporarily leaving the premises, resulting in wasted electrical energy.

The present invention automatically turns on or off the indoor power supply according to when the user enters or leaves the room.
The purpose is to provide an indoor power control system for hotels, etc. that contributes to energy savings.

The present invention will be specifically described below based on embodiments shown in the drawings.

1 to 3 show the card lock used in the present invention attached to the door of a hotel guest room, but the present invention is not limited to guest rooms, but can also be implemented in conference rooms and other rooms. can also be applied to various facilities other than hotels.

The illustrated door 1 includes a knob 21 that protrudes inward and outward of the door,
22 and the latch bolt 2 that appears on the side end surface of the door.
The outer knob 22 is fixed to the door 1,
The inner knob 21 is connected to the latch bolt 2 and the door 1 is connected to the latch bolt 2.
It is rotatably attached to. The latch bolt 2 has a tapered portion 23 on its outer surface, and therefore easily engages in a latch engagement groove 30 (described later) while retracting, but is prevented from escaping from the groove 30.

A latch engagement groove 30 equipped with an electric lock mechanism 4 is provided on the opening end face of the door wall 10, and a detection piece 41 of a door detection switch for detecting the open/closed state of the door 1 is disposed below the groove so as to be freely retractable. has been done. Further, a card reader 5 having a card insertion groove 50 in the center is attached to the outer surface of the wall, and a card setting section 7 is provided on the inner surface of the wall.

The electric lock mechanism 4 includes a lock member 40 disposed in the latch engagement groove 30 and a solenoid (not shown) built into the case 3, as shown in FIG. This solenoid is normally connected to the locking member 40.
The lock member 40 is prevented from withdrawing (indicated by an arrow in FIG. 3), but is urged to retract in response to an unlock command from the controller 6, allowing the lock member 40 to withdraw. Therefore, when a force in the door opening direction is applied in the unlocked state, the latch bolt 2 pushes the lock member 40 into the latch engagement groove 3.
0 and escape from the groove 30.

FIG. 4 shows the card setting section 7. As shown in FIG. This card set section 7 is a means for confirming whether or not a customer is present in the room. A card box 73 equipped with a card insertion slot 72 is mounted on a board 71, and it is possible to confirm whether or not a card is present in the box 73. A microswitch or other card detection means (not shown) is provided to detect the card. Therefore, when the card detection means detects the presence of the card 51, it means that the customer is in the room, and the lamp 74 on the board 71
lights up. Note that this lamp 74 is operated using a DC power source.

FIG. 5 shows a card 51 for unlocking. A magnetic information recording section 52 is provided on the surface of the card 51, and various information a to e regarding the hotel number, room number, secret number, card issue date, and length of stay are recorded at the front desk when a customer checks in. . Note that the secret number information c is for preventing card forgery, and is updated every time a customer changes.

FIG. 6 shows an example of the circuit configuration of an indoor power supply control device embodying the present invention.

The card reader 5 reads the card information a to e with a magnetic head and sends it to the buffer memory 61 of the controller 6. The buffer memory 61 is for temporarily storing the read information, and when the stored information exists, it is transferred to the card reader 5 from the card 51.
You can confirm that it has been set. The door detection switch 42 detects the open/closed state of the door, and is turned on and off when the detection piece 41 is pressed and released. The card detection means 70 detects the presence or absence of the card 51, and turns on and off when the card 51 is inserted into and removed from the card set section 7. The storage device 62 stores card information a
Stores data regarding the hotel number, room number, secret number, date, and length of stay for comparison with ~e.
FIG. 7 shows a storage area m for these data, and areas m ₁ and m ₂ are fixedly stored with each data such as a hotel number and a room number. Data of a specific secret number that changes each time the customer changes is written in area _m3 . The current date is written in area _m4 , updated daily by the clock mechanism 63.
The remaining days of stay are written in area _m5 while being subtracted every time a specific time (for example, hotel check-out time) arrives. The arithmetic processing unit 64 compares the card information with the stored data and reads the card 7.
It executes calculations such as determining the authenticity of the electric lock mechanism 4, and sends a signal instructing the electric lock mechanism 4 to be unlocked and a reset signal to the unlocking signal storage circuit 65, as well as a signal instructing power on and a reset signal. Controls the operation of sending power to the power control circuit 8, etc.
In the figure, a drive circuit 43 is a circuit for energizing and deenergizing a solenoid 44 of the electric lock mechanism 4, and a drive circuit 81 is a circuit for energizing and deenergizing a power control power relay 82 interposed in the power control circuit 8. be. The alarm device 9 is for letting the customer forget to take out the card, and includes a buzzer, a chime, and other devices.

Figure 8 shows the flow of the above device with reference numerals 100 to 121.
Indicated by

First, at the start of step 100 (hereinafter referred to as "step 100"),
The door 1 of the passenger compartment is closed, the electric lock mechanism 4 is in a locked state, and the power control circuit 8 is opened.
Therefore, there was no power supply to the various electrical appliances in the room, making them inoperable.

The customer is now using the card insertion slot 50 of the card reader 5.
When the card 51 is inserted and set, the card information a to e is read by the magnetic head of the card reader 5 and temporarily stored in the buffer memory 61, so that the determination in step 101 "Is there a card input?" is "YES". becomes. If the determination in step 101 is “NO”, routes 130 and 13
1, a "card waiting" state is formed.

Next, in step 102, the arithmetic processing unit 64 reads the card information set in the buffer memory 61 and the data stored in the storage area m of the storage device 62, and compares them to determine the authenticity of the card 51. In this case, before the new customer enters the room, the secret number data of the previous customer is stored in the storage device 62, so the comparison result between the card information c regarding the secret number and the stored data will be inconsistent. . In such a case, the card information d regarding the card issue date and the date data are then compared, and since they match, the area _m3 of the storage device 62 is rewritten with the new customer's secret number data, and the area _m5 is rewritten with the new customer's secret number data. The remaining days of the stay, for example, in the case of "1 night and 2 days", data corresponding to "1" is written. Thus step 103
The judgment of "Is the card correct?" is "YES", and from now on, the card information regarding the hotel number, room number, secret number and the corresponding stored data match, and the data regarding the length of stay is "YES". If it is not "0", the determination at step 103 is "YES". On the other hand, if a mismatch occurs in any of the items, or if the data regarding the length of stay is "0", the determination at step 103 is "NO".

If the determination in step 103 is "YES", the contents of the buffer memory 61 are cleared, the solenoid 44 of the electric lock mechanism 4 is retracted and energized, the lock member 40 is allowed to move out, and the lock is electrically "unlocked". (Steps 104 and 105).
On the other hand, if the determination at step 103 is "NO", the contents of the buffer memory 61 are similarly cleared (step 106), but the electric lock mechanism 4 remains locked and enters a standby state waiting for a card.

When it is "unlocked" in step 105, a timer included in the clock mechanism 63 starts (step 1).
07), the electric lock mechanism 4 remains unlocked for a certain period of time, and the door 1 can be opened during this time. This length of time is set to a time sufficient for the customer to open the door 1 after setting the card, for example, about 10 seconds. When the customer pushes the door 1 before the timer times up (determination at step 108 is "NO"), the latch bolt 2 pushes the locking member 40 into the latch engagement groove 30 and escapes from the groove 30. is opened, and the determination at step 109 becomes "YES". This opening of the door 1 is detected by the door detection switch 42, and upon receiving this detection signal, the arithmetic processing unit 64 returns the electric lock mechanism 4 to the locked state, and also issues a power-on command to the power control circuit 8 to drive the electric lock mechanism 4. The power control power relay 82 is closed by the circuit 71 (steps 110 and 11).
1). In the locked state of step 110, by applying a force in the door closing direction, the latch bolt 2 is retracted by the action of the tapered portion 23 and easily engages the latch engagement groove 30, so that the door 1 cannot be closed. There is no problem with the configuration operation. On the other hand, when the passenger does not open the door 1 before the time-up (the determination in step 109 is "NO" and the determination in step 108 is "YHS"), the electric lock mechanism 4 is activated in step 11.
2 returns to the locked state in the same way, but in this case door 1
The opening operation is no longer possible, and the device enters a "wait for card" standby state.

In this manner, when the indoor power source is turned on in step 111, power is supplied to each electrical appliance in the room, and each guest can operate each appliance at will.

When the guest enters the guest room and closes the door 1, the determination in step 113 becomes "YES", and then in step 114 it is determined whether or not the user is in the room. In this experimental example, the card setting unit 7 detects whether the customer is in the room or not, and when the customer sets the card 51 in the card setting unit 7,
The card detection means 70 detects this and steps 1.
The determination of No. 14 “Are you in the room?” is “YES”.
On the other hand, if the card 51 is not set in the card set section 7, or if the card 51 is not set in the card set section 7,
If 1 is taken out, it becomes an absent state and the determination at step 114 becomes "NO".

Next, when the customer goes out temporarily or checks out, if he opens the door 1 without taking out the card 51 from the card setting section 7, the determination in step 115 becomes "YES", and the alarm device 9 is activated.
The customer is notified that he/she has forgotten to take the card (step 116). If the determination in step 115 of "Do you open the door?" is "NO", a standby state of "waiting for room exit" is established.

If the user takes out the card 51 from the card set section 7 and goes out, the determination of "Are you in the room?" at step 114 becomes "NO" and the process proceeds to the next step 117. In step 117, it is determined whether the user rotates the inner knob 21 to open the door 1 and subsequently closes the door 1, and the answer is "YES".
Upon determination, a reset signal is issued to the power control circuit 8, and the drive circuit 71 opens the power control power relay 82, and the indoor power supply is cut off (step 1).
18). As a result, the power supply to each electrical appliance in the room is stopped, and even if any electrical appliance is in operation, its operation is forcibly stopped. Note that if the determination in step 117 ``door closed after opening?'' is ``NO'', the vehicle enters a standby state of ``waiting for door operation'' around routes 31 and 130.

When the power is turned off in step 118,
The timer of the clock mechanism 63 starts (step 119), and when the set time of about 1 minute has elapsed,
The determination in step 120 is "YES", and the "power off" state is confirmed. On the other hand, in step 117, if the customer closes the door 1 without going outside, and if the card 51 is set in the card setting section 7 again before time-up, the determination in step 120 is "NO" and the determination in step 121 is "NO". YES”
Then, the process returns to step 111 via route 131 and immediately returns to the "power on" state.

As described above, the present invention constitutes an indoor power control system for a hotel or the like using a card on which predetermined information is recorded, a card lock, a door detection switch, a card detection means, and an arithmetic processing unit, and When the lock mechanism is unlocked and the door detection switch detects that the door is open, the processing unit outputs a signal instructing to turn on the indoor power, and the card detection means detects the absence of a card and the door detection switch is activated. When the computer detects that the door has been opened and then closed, the processing unit outputs a signal to turn off the power in the room, so guests at hotels, etc. can check out or temporarily go out with electrical appliances still in operation. In this case, the operation of the appliance is forced to stop, thereby reducing the waste of electrical energy. Moreover, when a customer checks in or returns from going out, the electric appliances will automatically become ready to operate when the door is unlocked and the door is opened, so that the customer will not feel any inconvenience. achieve remarkable results.
