Multi-channel control circuit system for vending machine

Abstract

The invention discloses a multi-channel control circuit system for a vending machine, and particularly relates to the technical field of vending machines. According to the multi-channel control circuit system for the vending machine, the defect that existing vending machine equipment only can operate independently, and thus merchants cannot conduct unified management remotely is overcome. The multi-channel control circuit system for the vending machine comprises a control circuit, a network background and a touch screen. The control circuit comprises a main control circuit, a power circuit, acontrol signal output circuit, a feedback signal input circuit, a network port circuit, a communication circuit and a storage circuit. The control circuit controls an actuator of the vending machine and receives feedback signals of a sensor so as to achieve manufacturing of beverages, self-test of the equipment and calculation of residual materials. Data manual transmission between the control circuit and the touch screen is achieved through the communication circuit. The main control circuit conducts manufacturing according to order information sent by the touch screen and transmits manufacturing states back to the touch screen in the manufacturing process. The control signal output circuit comprises a photoelectric isolation circuit and a voltage drive circuit.

Description

technical field [0001] The invention relates to the technical field of automatic vending machines, in particular to a multi-channel control circuit system for automatic vending machines. Background technique [0002] With the development of people's living standards, automatic vending equipment is playing an increasingly important role in people's lives. The beverage vending machine is a vending machine that makes beverages by processing semi-finished products on site. , this kind of vending machine has more complex peripherals, so it needs a circuit control system with powerful control functions. At present, some domestic manufacturers choose to use PLC as the main control component to control the actuator. Although this method is easy to realize the production process sequence, the hardware cost is high, and it is not easy to communicate with the non-industrial control host computer or the network background, and cannot support online payment method. [0003] The existin...
