Description

[Detailed Description of the Invention] The present invention is a method of checking the status of taking out the contents of a refrigerator installed in each guest room of accommodation facilities such as hotels and inns (hereinafter simply referred to as hotels) at the front desk, counter, etc. (hereinafter simply referred to as front desk).
This invention relates to a centralized management system for refrigerators.

Traditionally, each hotel room has been equipped with a refrigerator containing beer, soft drinks, and other contents, and guests can take out and consume the contents according to their tastes. Billing was done by having a maid or boy go to the guest room, find out what was consumed and how many bottles were consumed, and then issue a bill.

However, such a method requires a lot of manpower, lacks promptness, and causes inconveniences such as omissions in billing.

The present invention has been made to eliminate such inconveniences, and is a centralized management system for refrigerators that can centrally manage, display and record the consumption status of the contents stored in refrigerators installed in each guest room. The purpose of this service is to save labor and speed up bill settlement operations, as well as reduce the effort required to replenish the contents of the refrigerator.

The present invention has a feature in such a centralized control system for refrigerators, particularly in a signal transmission method for transmitting the status of taking out the stored contents from a refrigerator in a guest room to a central control device installed at the front desk.

Generally, the following two methods can be considered as methods for transmitting signals from the guest room refrigerator to the central control device.

(1) Refrigerators only have a built-in switch that generates a single pulse every time the stored contents are taken out, and each time the contents are taken out, the single pulse is sent to a central control device to store the contents of the device's memory. A method of reading out, displaying, and recording.

(2) A method in which the refrigerator has a built-in memory and the status of the removal of stored contents is stored in the memory, and the stored contents are transmitted to a central control device for display and recording as necessary.

Although the method (1) above requires a complicated central control device, the mechanism added to each refrigerator is extremely simple, so it is suitable for large hotels with many guest rooms.

In the method (2), although the centralized control device can be manufactured at low cost, each refrigerator has a relatively complicated structure, so it is suitable for small hotels and inns with a small number of guest rooms.

The present invention relates to method (2) of the above methods,
The details will be explained below with reference to the drawings.

FIG. 1 is a block diagram showing the outline of the system of the present invention. In the same figure, 10 is a central management device located at the front desk, and a refrigerator 30 installed in each guest room is connected via a transmission line 20. It is connected to .30...

This transmission line 20 is connected to each refrigerator 30.3 from the central management device side.
A type line 21 transmits a type designation signal for specifying the type of contents stored in the refrigerator to the 0... side, and from each refrigerator 30, 30... side to the central management device 10 side. A quantity line 22 for transmitting the consumption quantity of the contents; a clearing line 23 for transmitting a clearing signal for clearing the counting contents of the counter described later from the central management device 10 to each refrigerator 30, 30, etc.; A refrigerator line 24 transmits a refrigerator designation signal for designating a specific refrigerator among the refrigerators 30, 30, . . . from the central management device 10.

As shown in FIG. 2, the central control device 10 includes a clock pulse generator 11 and a central counter 12 that counts the clock pulses from the device 11 and outputs them in the form of a binary signal.
, a clock decoder 13 that decodes the binary output of the counter 12 and converts it into a latch signal, and refrigerators 30 and 3.
latch memory 14.14.in which the consumption quantity signal obtained via the quantity line 22 from 0... is introduced and stored;
..., a decoder 15.15... that decodes the contents of the memory 14.14..., and the decode output of the decoder 15.15... A display device 16, 16, and a clear switch 17 for putting a clear signal on the clear line 23.
, the specification switch 18.18 for specifying each of the refrigerators 30, 30, and so on, and which refrigerator Indicator lamp 19.19... to display whether it is specified.
. . . and the central counter 12, 2.
The expansion power is 30.30% for each refrigerator through 21 product lines.
. . . and the specified switch i s
, is-... are individually connected to the corresponding refrigerators 30, 30, . . . via the refrigerator line 24.

In addition, each refrigerator 30, 30..., as shown in Fig. 3, has type switches 31, 31, etc. whose contacts turn ON each time the stored contents are taken out, and the switch 31.
．． 31 ··························
2. Counters 33, 33, .
Three data selectors 34, 34.34 to which binary outputs having respective weights are input, a clear signal obtained from the clear line 23, and a refrigerator designation signal obtained via the refrigerator line 24. The gate output of the AND gate 35 is applied to the reset terminal of each of the counters 33, 33, . . . and the data selector 34. ，
34. The output of the selector 34 becomes a consumption quantity signal and is output to the quantity line 22, and the product specification signal obtained via the product line 21 is sent to the data selectors 34, 34.
．． 34 and further obtained via the refrigerator line 24, the refrigerator designation signal is applied to the data selector 34, 34.34.
is applied to the strobe terminal.

The triangles shown in Figures 2 and 3 are line drivers and line receivers, and in these figures, each refrigerator 30.30 can contain up to 8 types of contents. An example is shown in which a maximum of seven can be stored.

Therefore, in the initial state (say, each refrigerator 30, 30...
. . . The count contents of each counter 33, 33 . . . are all zero.

If the guest takes out the contents, for example, a bottle of beer, from the refrigerator 30, the contact point of the beer type switch 31' is turned on, and one pulse passes through the waveform shaping circuit 32 and is sent to the counter 33'. is applied to the counter 33', and the count content of the counter 33' is set to 1.

When more beer is taken out, the content of this counter 33' becomes 2.

In the case of taking out other contents, the contacts of the type switches 31, 31, etc. corresponding to each type are similarly turned on, and the corresponding counters 33, 33...... Remember.

At this time, each counter 33, 2 from 33...
° 21. A 3-bit binary output with a weight of 22 is applied to the data selectors 34, 34.34, but since no refrigerator designation signal is applied to the strobe terminal, they do not function as data selectors.

On the other hand, on the central control unit 10 side, the clock pulses from the clock pulse generator 11 are counted by the central counter 12, and the 3-bit binary output thereof becomes a type designation signal and is sent to each refrigerator 30 . 30...
... and is converted into eight latch signals by the clock decoder 13.

Even if the product type designation signal is printed on the refrigerators 30, 30, . . . , each data selector 34, 34.3
Since no signal is applied to the strobe terminal No. 4, the consumption quantity signal is not output.

For example, consider a case where a guest in a certain guest room requests to check out.

The front desk person charges the guest room charge, etc., but at that time, it is necessary to know the type and quantity of the contents taken out of the refrigerator 30 installed in the guest room, and to bill the guest accordingly. There is.

Then switch 18, 1 to specify the guest room where this guest stayed.
8. Operate and specify.

For example, when the designated switch 18' of the refrigerator 30' is operated, a refrigerator designated signal is transmitted to the refrigerator 30' via the refrigerator line 24, so this signal is printed on the strobe terminal of each data selector 34, 34, 34. jJ is selected and a select operation is performed.

Therefore, in response to the product specification signal obtained via the product line 21, the count contents of the counters 33, 33, . transmitted to.

On the other hand, the consumption quantity signal transmitted to the central management device 10 is transmitted from the clock decoder 13 to the latch memo IJ 1 4 . 1 4...
... will be introduced and memorized in sequence.

The consumption quantity for each product type stored in the latch memory 14.14... is stored in the decoder 15.15...
The information is decoded and displayed on the display device 16, 16, etc. in the form of examples of beer, how many bottles of juice, etc.

At this time, it can be confirmed from the display lamps 19, 19, . . . which refrigerator's consumption status is being read out.

When the checkout process is completed, clear switch 17
When the clear signal is transmitted to the refrigerator 30, 30, . . . via the clear line 23 by operating the The logical product is obtained, and the counter 33
, 33, . . . are cleared, and the state becomes ready for the next guest's check-in.

As is clear from the above description, the present invention includes a counter whose count is incremented each time the contents are taken out of the refrigerator, and a data selector which sequentially sends the count of this counter to a central management device. The central control unit is equipped with a latch memory that sequentially stores the count contents sequentially sent out by this data selector, and the contents of this memory are displayed.The refrigerator installed in each guest room is installed at the front desk. You can centrally manage the contents of the refrigerator, saving labor, and at the touch of a switch, you can immediately know the consumption amount of the contents of the refrigerator, preventing omissions in billing at checkout, and making payment procedures easier. This will be done promptly, and guests will no longer be kept waiting at check-out.

In addition, in the present invention, each refrigerator stores the number of items to be taken out, and the central management device reads and outputs the stored amount as necessary, so the central management device can be small in size, and the number of guest rooms can be reduced. Suitable for setting up in small hotels and inns with few guests.

Furthermore, the present invention is configured to clear the number of stored items stored in the refrigerator to be taken out using a clear switch provided in the central processing unit. It is possible to clear the number of items stored in the refrigerator to be taken out and quickly collect them in order to respond to the next check-in.
