Abstract

The hotel vending network includes a central control at the hotel main desk and a vending unit in each hotel guest room. The microprocessor controlled vending units include a display arrangement for displaying prices of articles to be rended and a user allocatable keyboard for use in article selection and final purchase from the vend unit. Each purchase is a cooperative action between the central control and a vend unit and is completed by an acknowledgment signal from the vending unit which signal is required before actual billing of a rended article occurs. The keyboard is also used to control service access to the vending unit by means of passwords assigned from the central control.

Claims

1. A hotel room vending network comprising:

a central control unit;

a plurality of vending units remote from said central control unit, each vending unit containing a plurality of vendable articles and comprising vending unit control means connected to said central control unit;

display means in each of said vending units;

said central control unit comprising means for transmitting price information representing the prices of a plurality of said vendable articles contained by at least one of said vending units to the vending unit containing those articles;

storage means in each of said vending units for contemporaneously storing price information for a plurality of said vendable articles received from said central control unit; and

said vending unit control means comprises display control means responsive to operator interaction for retrieving price information from said storage means and controlling said display means to display the price of one of said vendable articles represented by said price information.

2. The network of claim 1 wherein each of said vending units comprises means for transmitting to said central control unit a price request signal requesting price information;

and

said central control unit comprises means responsive to said price request signals for transmitting price information to said requesting vending unit for storage thereby.

3. The network of claim 2 wherein each of said price request signals requests price information for all of the vendable articles contained by the requesting vending unit;

and

said central control unit responds to the price request signals by transmitting to the requesting unit price information representing the prices of all said vendable articles contained by the requesting vending unit.

4. The network of claim 7 wherein each of said vending units comprises a plurality of vending access means each for controlling access to an article contained by said vending unit and said transmitted price information comprises a price associated with each of said vending access means.

5. The network of claim 1 comprising means in said central control unit, for storing first price information associating first prices with the articles contained by said vending units and for storing second price information associating second prices with the same articles contained by said vending units;

and

said means for transmitting price information comprises means for transmitting to said vending units, price information selectively read from said first and said second stored price information.

6. The network of claim 5 wherein said central control unit comprises means for generating time of day signals;

and

said means for transmitting price information is responsive to said time of day signals for the selective reading of price information from said first and said second stored price information.

7. The network of claim 5 wherein each of said vending units is identified by a unique address;

and

said means for transmitting price information is responsive to the unique address of one of said vending units which is to receive price information, for the selective reading of price information from said first and said second stored price information.

8. A method of operating a hotel room vending system comprising a central control unit connected to a plurality of remotely located guest room vending units each including vending unit control means, the method of vending an article contained by one of said guest room vending units comprising:

transmitting from said one guest room vending unit to said central control unit a request to purchase an article contained by said one vending unit;

transmitting from said central control unit, in response to said request to purchase, a permission to purchase signal to said one guest room vending unit;

permitting, at said one guest room vending unit in response to said permission to purchase signal, the purchase requested in the request to purchase; and

transmitting an acknowledgement signal from said one guest room vending unit to said central control unit upon completion of the purchase of said article.

9. The method of claim 8 further comprising recording the purchase of said article in said central control unit only after said acknowledgment signal is received by said central control unit.

10. The method of claim 8 wherein said one vending unit comprises display means and said method comprises:

receiving at said one vending unit, before the transmission of said request to purchase, a request to display the price of said article and displaying by said display means, the price of said article.

11. A hotel room vending network comprising:

a central control unit connected to a plurality of vending units;

said central control unit comprising means for generating a password for each of said vending units and means for transmitting each generated password to the vending unit associated therewith;

each of said vending units comprising a vending unit controller for receiving and storing in a storage means the password associated therewith;

input means at each vending unit responsive to operator action for generating signals representative of a password;

means at each vending unit for comparing said password signals with the password stored in said storage means; and

means responsive to said comparing means for granting service access to the vending unit only when said password representing signals represent the password stored in said storage means.

12. The network of claim 11 wherein said central control means comprises means for transmitting a new password to selected ones of said vending units;

and

said vending unit controller comprises means for replacing the password stored in said storage means with said new password.

13. A method of operating a vending unit containing a plurality of articles to be vended and comprising a plurality of article push buttons each associated with one of said articles, a buy push button and a display means, said method comprising:

displaying, in response to the press of an article push button, the price of the item associated with the pressed article push button;

illuminating the buy push button at substantially the same time that the price is displayed in said displaying step;

terminating the display provided in said displaying step and the illumination of said lamp when said buy push button is not pressed within a predetermined period of time after commencement of said displaying step; and

completing the vending of said article when said buy button is pressed within said predetermined period of time.

14. A hotel room vending network comprising:

a central control unit;

a plurality of vending unit containing a plurality of vendable articles and comprising vending unit control means connected to said central control unit;

said central control unit comprising means for transmitting password information to the vending units;

storage means in each of said vending units for storing password information received from said central control unit;

input means, at each of said vending units, responsive to operator action for generating service access request signals including password signals; and

said vending unit control means is responsive to said service access request signals for retrieving said password information stored in said storage means and for selectively granting and denying service access to the vending unit.

15. The network of claim 14 wherein said vending unit control means grants service access to said vending unit only when the password signals represent the same password as said stored password information.
