Multi-channel detection intelligent antitheft alarm applied to antitheft door

The invention discloses a multi-channel detection intelligent antitheft alarm applied to an antitheft door. An STC89C55RC microcontroller is used for detecting detection signals obtained by a vibration detection sensor, a laser detection sensor and a heat release infrared sensor mounted at the antitheft door in real time, and if an illegal invasion signal is detected in a time segment in need of alarming, a hard light alarm and a sound alarm are output, an invader is driven away on site and an alarm is given to a host or a security guard. If a remote alarm mode is set, a remote telephone dial-up alarm can be started and the intelligent antitheft alarm gets in touch with the host or a security duty room.
