Abstract
A door and window remote-controlled laser anti-theft alarm provided by the utility model relates to the guard field, and is an anti-theft alarm device installed on a door or a window. When a person intrudes, a laser net generated by the device and distributed on the door or the window can be blocked unavoidably, so as to cause the device to send out an alarm signal, thereby playing an anti-theft role. The anti-theft alarm device is technically characterized in that a laser beam sent out and used for forming the laser net passes through pseudo random data generated by an embedding type microcontroller and an ASK signal modulated by high frequency impulse simultaneously; the effect of sunlight and other strong light, as well as human disturbance can be effectively avoided by adopting the high frequency modulation; and after the pseudo random data is processed by the microcontroller, the misreport can be avoided effectively. The control operation is carried out by using a remote controller; dual-track power supply is carried out by adopting a solar battery and alternating current municipal power; and a stand-by battery is provided, thereby avoiding the problem that the anti-theft alarm device can not work when the connection of the municipal power is difficult and the power failure occurs. A dedicated circuit for achieving the high light focusing function is designed, thereby simplifying the installation and the debugging work.
Description
Technical field
