Abstract
An anti-damage alarm system for a vending machine includes an accelerometer, a processing unit, and an alarm device. The accelerometer measures accelerations of the vending machine. The processing unit calculates vibration angles of the vending machine according to the measured accelerations of the vending machine, and determines whether an alarm condition is met according to the vibration angles of the vending machine. When the alarm condition is met, the alarm device emits an alarm. An anti-damage alarm method is also disclosed.
