<p>PROBLEM TO BE SOLVED: To provide an alarm system capable of promptly notifying a person of the fact that a vending machine is destroyed, and a method therefor.SOLUTION: The alarm system comprises a processor, a controller, an alarm device, and a gravity sensor. The gravity sensor detects an acceleration value of a vending machine. The processor converts the acceleration value into a vibration angle of the vending machine, converts a change of the acceleration value into a change of the vibration angle of the vending machine, and determines whether the vibration angle and the change thereof reach an alert condition. When they reach an alert level, the controller performs control so that the alarm device outputs alarm sound.</p> |
