METHOD FOR AUTOMATIC CONTROL OF EFFICIENCY OF PASSIVE PROTECTION OF ELECTROMAGNETIC PROTECTED STRUCTURE Russian patent published in 2021 - IPC G01R31/00 G01R29/08 

FIELD: automatic control.

SUBSTANCE: invention relates to the field of automatic control of the effectiveness of passive protection (PPE) via the radio channel of an electromagnetically protected construct (EMPC) and can be used for continuous or periodic monitoring of PPE EMPC, as when exposed to external electromagnetic fields on a radio electronic device (RED) installed inside the EMPC, and when shielding its own spurious electromagnetic radiation (SER) of the RED installed inside the EMPC. The invention provides the possibility of automatic control of the PPE EMPC by radio channel with the function of identifying the radio channel and testing the radiation unit (RU) 1 and the receiving unit (RCU) 2, with the function of the automatic mode of self-monitoring of the operability and reliability of the PPE measurements, with a function that excludes the possibility of false triggering due to external destructive electromagnetic effects, with the function of automatic blocking of the operation of the electronic device located inside the EMPC, when the PPE value deviates from the specified threshold value, with the PPE monitoring before each subsequent operation of closing the EMPC door and turning on the general power supply unit for the EMPC, with the ability to select the type of identification signal for the "Friend/Foe" mode and select the type of signal and select the type of modulation of the control signal radio channel testing, with the ability to select the type of the base signal (BS) and select the type of BS modulation for measuring the PPE value, with the possibility of matching the complex input impedance of the antenna module BI with the impedance of the antenna-feeder path according to the criterion of the minimum value of the standing wave ratio (SWR), with the decision function "Work" or "Prohibition of Work" based on the results of measurements of the PPE EMPC and comparison with the threshold value of the PPE, with a detailed display of all information on the visualization module (VM).

EFFECT: expansion of functionality.
