Vending machine and unlocking, locking and control method and device thereof

LI HONGGANG / XU DA / LI XIAOLONG

The invention provides a vending machine and an unlocking, locking and control method and device.The vending machine comprises a motor and a spring bolt, the motor is used for driving the spring bolt to move to a locking state or an unlocking state, and the unlocking method comprises the steps that in response to unlocking input, the motor is controlled to execute unlocking action; in the process that the motor executes the unlocking action, a first current value of the motor is detected; controlling the motor to stop running based on the abnormal condition of the first current value; and based on the condition that the first current value returns to normal, the motor is controlled to complete the unlocking action. According to the unlocking method of the vending machine and the vending machine, unlocking is achieved in a motor driving mode, the first current value of the motor can accurately reflect the current running resistance of the motor, then the accuracy of lock state detection is improved, in addition, when the motor runs abnormally, the unlocking action can be stopped, and the unlocking efficiency is improved. The unlocking action is executed only when the motor operates normally, the damage probability of the lock can be reduced, and the fault probability of the vending machine is reduced.

本发明提出了一种售货机及其开锁、关锁和控制方法以及装置，售货机包括电机和锁舌，电机用于驱动锁舌运动到关锁状态或开锁状态，开锁方法包括：响应于开锁的输入，控制电机执行开锁动作；在电机执行开锁动作的过程中，检测电机的第一电流值；基于第一电流值异常的情况，控制电机停止运行；基于第一电流值恢复正常的情况，控制电机完成开锁动作。本发明提出的售货机的开锁方法，售货机通过电机驱动的方式实现开锁，而电机的第一电流值可以准确的反映出当前电机运行的阻力，进而提升对锁具状态检测的准确性，并且，当电机运行异常时可以停止开锁动作，在电机运行正常时才执行开锁动作，可以降低锁具的损坏概率，降低售货机的故障概率。
