Abstract
Broken glass detector is designed to detect a function of broken glass detectors.When the invasion of criminals trying to break the glass cases, can be sent alarm signals.This design will detect high-frequency noise and broken glass detection percussion glass, air flow, the two acoustic detection technology together, when the two detection technology detected at the same time, and meet a certain relationship between the occurrence of timing, the system would trigger alarm, Has effectively improved the reliability of the system and anti-jamming capabilities.
