Abstract

A vending machine monitoring method used in a vending machine monitoring system, which includes an automatic vending machine and a monitoring system that is attached to the automatic vending machine and uses a microprocessor to read in data signals transmitted between the main controller and peripheral apparatus (card-slide unit, bill acceptor, license recognition unit and coin slot unit) of the automatic vending machine through a connection interface, to process fetched data signals into waveform signals, to indicate any error message through an indicator light module, and to report processed waveform signals to an external remote system through a transmission module for display and further analysis and check of income.

Claims

1. A vending machine monitoring system, comprising an automatic vending machine and a monitoring system installed in said automatic vending machine for monitoring operation of said automatic vending machine, wherein said monitoring system comprises:

a connection interface electrically connected to said automatic vending machine;

a microprocessor electrically connected with said connection interface and adapted for reading in data signals from said automatic vending machine, processing fetched data signals into waveform signals, and reporting the waveform signals to an external remote system; and

a transmission module electrically connected to said microprocessor for enabling said microprocessor to transmit the processed waveform signals to said external remote system for display the exceptional statue and the information of said automatic vending machine.

2. The vending machine monitoring system as claimed in claim 1, wherein said monitoring system further comprises a memory electrically connected to said microprocessor and controllable by said microprocessor to store said waveform signals.

3. The vending machine monitoring system as claimed in claim 1, wherein said connection interface is one of CCTalk, RS232, MDB and Parallel interfaces.

4. The vending machine monitoring system as claimed in claim 1, wherein said connection interface is electrically connected to a main controller of said automatic vending machine for enabling said microprocessor to read in signals of data communicated between said main controller and one of a set of peripheral apparatus of card-slide unit, bill acceptor, license recognition unit and coin slot unit of said automatic vending machine, and signals of detection message including motor error/service inquiry message, peripheral apparatus error message, message of amount of bills received by said bill acceptor, message of amount of coins received by said coin slot unit, message of value of commodity purchased and commodity dispensing message.

5. The vending machine monitoring system as claimed in claim 1, wherein said transmission module is a wired transmission module selected from the group of wired public telephone network transmission interface, wired Internet transmission interface and DSL (Digital Subscriber Line) transmission standards.

6. The vending machine monitoring system as claimed in claim 1, wherein said transmission module is a wireless transmission module prepared subject to one of GSM (Global System for Mobile communications), GPRS (General Packet Radio Service), Bluetooth, Wireless LAN (Wireless Local Area Network) and radio frequency transmission standards.

7. A vending machine monitoring method used in a vending machine monitoring system comprising an automatic vending machine and a monitoring system installed in said automatic vending machine and electrically connected with a microcontroller thereof to a main controller of said automatic vending machine (for reading in signals of data communicated between said main controller and one of a set of peripheral apparatus of card-slide unit, bill acceptor, license recognition unit and coin slot unit of said automatic vending machine and signals of detection message and processing fetched signals into waveform signals for storing in a memory of said vending machine monitoring system and reporting the waveform signals to an external remote system through a transmission module of said vending machine monitoring system the vending machine monitoring method comprising the steps of:

(A) Start up said main controller of said automatic vending machine to run initialization;

(B) Automatically detect any error, and then proceed to step (C) when an error occurs, or to step (G) when normal;

(C) Display the error message;

(D) Monitoring system reads in motor error/service inquiry message.

(E) Memory stores the error message;

(F) Report the error message to the remote system;

(G) Detect peripheral apparatus functioning, and then proceed to step (H) when an error detected, or to step (I) when no any error detected;

(H) Monitoring system reads in peripheral apparatus error message and then returns to step (E);

(I) Detect if there is any bill, coin or credit card inserted? And then return to step (B) when negative, or run to step (J) and step (K) when positive;

(J) Monitoring system reads in the amount of money received by the peripheral apparatus and then returns to step (F);

(K) Detect if there is any purchase action or not, and then return to step (B) when negative, or run step (L) and step (N) when positive;

(L) Monitoring system reads in the message of the value of the commodity selected;

(M) Memory stores the commodity value purchased, and then return to step (F); and

(N) Start up the motor-operated conveyor system to dispense the purchased commodity.

8. The vending machine monitoring method as claimed in claim 7, wherein the microprocessor of said monitoring system reads in signals of data communicated between said main controller and one of a set of peripheral apparatus of card-slide unit, bill acceptor, license recognition unit and coin slot unit of said automatic vending machine, and signals of detection message including motor error/service inquiry message, peripheral apparatus error message, message of amount of bills received by said bill acceptor, message of amount of coins received by said coin slot unit, message of value of commodity purchased and commodity dispensing message.

9. The vending machine monitoring method as claimed in claim 7, further comprising the steps of:

(O) Sensor detects dispensing of the purchased commodity to a commodity dispensing outlet of the automatic vending machine after the step (N); and

(P) Monitoring system reads in commodity dispensing message, and then proceed to step (E) when no commodity is dispensed to the commodity dispensing outlet, or to step (F) when the purchased commodity has been dispensed to the commodity dispensing outlet.
