Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control system for an indoor power supply that supplies power to electrical appliances in each room in a facility such as a hotel, and in particular, the present invention relates to a method for controlling an indoor power supply that supplies power to electrical appliances in each room in a facility such as a hotel. The present invention also provides a new method for automatically controlling disconnection.

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 operation at the time of check-out, resulting in wasted electrical energy.

The present invention contributes to energy savings by automatically turning on or cutting off the indoor power supply according to when the user enters or leaves the room, by using the mechanism or function of the card-operated lock attached to the door. The purpose is to provide an indoor power supply control method for hotels, etc.

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

1 to 3 show a situation in which a card-operated lock related to the present invention is 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. It 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 to close the door 1.
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 is attached to the outer surface of the wall, and is configured to insert and remove a card into a central card insertion groove 50.

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

FIG. 4 shows a card 51 for unlocking operation. 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. . The secret number information c is for preventing card forgery, and is updated every time a customer changes.

FIG. 5 shows an example of a circuit configuration implementing the indoor power supply control method of 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 storage device 62 stores the hotel number, room number, secret number, current date, and the card information a to e.
Stores data regarding length of stay. FIG. 6 shows the storage area m for these data, where areas m ₁ ,
Data such as hotel number and room number are fixedly stored in _m2 . Data of a specific secret number that changes each time the customer changes is written in area _m3 . In area m ₄ , the current date is clock mechanism 63
It is updated and written daily. area
The remaining days of stay are subtracted and written into _m5 every time a specific time (for example, hotel check-out time) comes. The arithmetic processing unit 64 performs calculations such as determining the authenticity of the card 7 by comparing the card information and the stored data, and outputs a signal instructing the unlocking of the electric lock mechanism 4 and a reset signal thereof. It controls the operation of sending out to the signal storage circuit 65 and the operation of sending out a signal instructing power-on and its reset signal to the power control circuit 7. 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 71 is a circuit for energizing and deenergizing a power control relay 72 interposed in the power control circuit 7.

FIG. 7 shows the operation flow of the above device.

"Start" in step 81 means that the cabin door 1 is closed, the electric lock mechanism 4 is locked, and the power control circuit 7 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 82 "Is there a card input?" becomes YES. . In addition, if the judgment in step 82 is NO, "wait for card" for routes 101 and 102.
form the state of

Next, in step 83, the arithmetic processing unit 64
reads and collates the card information set in the buffer memory 61 with the data stored in the storage area m of the storage device 62 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. Therefore, the determination of "Is the card correct?" in step 84 is YES, and from now on, the card information regarding the hotel number, room number, and secret number matches the stored data corresponding to this, and the data regarding the length of stay is confirmed. If it is not "0", the determination at step 84 is YES. On the other hand, if there is a mismatch in any of the items, or if the data regarding the length of stay is "0", the determination at step 84 will be NO.

If the determination in step 84 is YES, the contents of the buffer memory 61 are cleared, the solenoid 44 of the electric lock mechanism 4 is retracted and energized, and the lock member 40 is energized.
The exit operation of the door is permitted, and the door is electrically "unlocked" (steps 85 and 86). On the other hand, if the determination at step 84 is NO, the contents of the buffer memory are similarly cleared (step 87), but the electric lock mechanism 4 remains locked and enters a standby state leading to the route 102.

When it is "unlocked" in step 86, the clock mechanism 63
starts the timer it has (step 88),
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 passenger presses the door 1 before the time-up (determination at step 89 is NO), the latch bolt 2 pushes the locking member 40 into the latch engagement groove 30 and escapes from the groove 30, so the door 1 opens and the process proceeds to step 90. The judgment is YES. This opening of the door 1 is detected by the door detection switch 42, and the arithmetic processing unit 6
4 returns the electric lock mechanism 4 to the locked state upon receiving this detection signal, issues a power-on command to the power control circuit 7, and causes the drive circuit 71 to close the power control power relay 72 (step
91, 92). In the locked state of step 91, 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, if the passenger does not open door 1 before time-up (step 90)
If the judgment in step 89 is NO and the judgment in step 89 is YES), the electric lock mechanism 4 returns to the locked state in the same way in step 93, but in this case, the door 1 can no longer be opened and is in a standby state leading to route 102. Become.

Thus, when the indoor power is turned on in step 92,
Electricity is supplied to each electrical appliance in the room, and guests can operate each appliance at will.

By the way, the arithmetic processing unit 64 is a clock mechanism 63.
The checkout time is checked based on the time data obtained, and if the judgment of "Is it checkout time?" in step 93 is YES, the contents of area _m5 in the storage device 62 are subtracted by 1, and the result corresponds to the subtraction result. Rewrite to data (step
94). When the value is "0", that is, when the checkout time for the day when the customer is supposed to leave the room arrives, a reset signal is issued to the power control circuit 7, and the drive circuit 71 activates the power control power relay 7.
2 is opened and the indoor power supply is cut off (step
96). As a result, the power supply to each electrical appliance in the room will be stopped, and even if any electrical appliance is in operation, its operation will be forcibly stopped.

In addition, step 93 "Is it checkout time?"
If the determination in step 94 is NO, or if the determination in step 94 is NO, the route 102 and then the route 101 will be in a standby state.

As described above, the present invention automatically turns on the power in the room when the door is opened by unlocking the electric lock mechanism, and automatically turns off the power in the room when the remaining date and time of the stay becomes zero. Even if a user checks out an electric appliance while it is still in operation, the operation of the appliance is forcibly stopped, thereby reducing the waste of electrical energy. Further, the present invention can be easily carried out by simply adding some functions to the card-using lock, and the present invention achieves excellent effects such as contributing to energy saving and achieving the purpose of the invention.
