Novel direct-current motor driving system of retail machine

Abstract

The invention discloses a novel direct-current motor driving system of a retail machine. The novel direct-current motor driving system comprises a control unit, a motor driving unit and a direct-current motor, wherein the motor driving unit comprises a first motor driving module, a second motor driving module and a third motor driving module, and the first motor driving module, the second motor driving module and the third motor driving module are all in bidirectional electrical connection with the control unit; output ends of the first motor driving module, the second motor driving module and the third motor driving module are electrically connected with the input end of the direct current motor. The system is advantaged in that the first motor driving module, the second motor driving module and the third motor driving module are configured to control the direct-current motor, and when the motor driving modules are over-temperature or break down, the control unit can automatically detect and switch the idle motor driving modules to drive the direct-current motor again for driving shipment; and therefore, the novel direct-current motor driving system of the retail machine is more stable in delivery.

Description

technical field [0001] The invention relates to the technical field of vending machines, in particular to a novel DC motor drive system for vending machines. Background technique [0002] A vending machine is a machine that automatically pays for the money you put in. Vending machines are common equipment for commercial automation. They are not limited by time and place, can save manpower and facilitate transactions. It is a new form of commercial retail, also known as a 24-hour micro supermarket. Common vending machines are divided into four types: beverage vending machines, food vending machines, comprehensive vending machines, and cosmetics vending machines. [0003] When the retail machine performs automatic delivery, the control unit sends a control signal to the motor drive module, and the motor drive module controls the DC motor to drive the delivery mechanism for automatic delivery. However, in actual use, when the motor drive module is long When the time-working ...

AI Technical Summary

Problems solved by technology

[0003] When the retail machine performs automatic delivery, the control unit sends a control signal to the motor drive module, and the motor drive module controls the DC motor to drive the delivery mechanism for automatic delivery. However, in actual use, when the motor drive module is long When the time-working chip is overheated or fails, the motor cannot be controlled, resulting in a failure to deliver. At this time, the customer needs to wait for the management personnel to come to the retail machine for on-site processing. The long waiting time affects the customer shopping experience and causes customer loss. At the same time, it is not convenient for the staff to manage the retail machines, and the work intensity is high, so it is impossible to make reasonable arrangements and plans for inspection and maintenance of the retail machines.
