METHOD FOR REMOTE INSTALLATION OF A COMBINED SECURITY ALARM Russian patent published in 2022 - IPC G01S13/00 

FIELD: object security systems.

SUBSTANCE: invention is intended for use in the object security system for detecting a moving intruder. The burglar alarm means includes two means of detection and is based on two physical principles - radio wave and wire-wave. The radio wave principle of detection is to change the frequency of the received radiation depending on the speed of the deviation of the receiver relative to the transmitter. When it enters the intruder detection zone, the signal reflected from it with a changed frequency through the receiver enters the mixer, which compares both signals and, if a frequency difference is detected, it enters through a band-pass filter for further processing and generating an alarm signal. The wire-wave principle of operation of the detection means is based on registering a change in the parameters of the electromagnetic field when the object of detection acts on the volumetric detection zone created between the emitting and receiving wires of the sensing element, and converting this change into an electrical signal. The method for remote installation of a combined detection tool is carried out using a helicopter-type lifting unmanned aerial vehicle, the payload of which is a portable mining kit PMK that shoots KPOM-2 cassettes containing combined detection tools.

EFFECT: increasing the efficiency of mobile detection tools by increasing their noise immunity by combining two detection tools based on different physical principles of operation, as well as by quickly installing them remotely.
