Method and device for controlling money box motor to start and self-service device

Abstract

The invention is suitable for the technical field of financial self-service terminals and provides a method and device for controlling a money box motor to start and a self-service device. The method comprises the steps of outputting a pulse signal with a preset duty ratio to a motor drive device when receiving a motor starting instruction to enable the motor drive device to drive the motor to rotate according to the pulse signal; simultaneously detecting and storing the quantity of hall signals output by a hall sensor when the motor rotates; judging whether the quantity of the hall signals is greater than a default value or not; and when judging that the quantity of the hall signals is greater than the default value, driving a PID controller to regulate the rotating speed of the motor to a target value, thus, the problem that the problem that the rotating speed cannot be regulated to the target value due to the fact that the motor cannot be normally started or the start displacement of the motor is overlarge in an existing money box motor starting method is solved.

Description

technical field [0001] The invention belongs to the technical field of financial self-service terminals, and in particular relates to a method, a device and a self-service transaction device for controlling the start-up of a cash box motor. Background technique [0002] Automatic teller machines are widely used in various commercial banks and postal savings, and their 24-hour self-service operation mode has brought great convenience to people. Wherein, the cash box is an essential device for the automatic teller machine to store banknotes. After the user uses the automatic teller machine to deposit and withdraw business, the cash box must return to the tongue hidden state so that the next business can be carried out normally, and the motor needs to be started and stopped many times during the tongue positioning process. Therefore, the normal start and stop of the cash box motor is the key to ensure the normal progress of the automatic teller machine deposit and withdrawal b...
