CONTROL AND INSPECTION COMPLEX FOR INSPECTION OF DOPPLER VELOCITY AND SPEED METERS Russian patent published in 2018 - IPC G01P21/00 G01P5/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a measurement technique, namely, devices for monitoring and measuring electrical parameters of aviation radio equipment, namely, Doppler velocity and drift meters. Control and test complex for checking the DISS contains a personal computer with software connected to a network filter and an uninterruptible power supply. In addition, it contains a software-controlled power supply unit with a direct voltage and a software-controlled power supply unit with an alternating voltage, and two measuring units connected via a switching panel to the control object. First measuring unit includes measuring modules that implement measuring channels of DC voltage and measuring channels of AC voltage. Second measuring unit contains the control tasks module that implements the measuring channel for reproducing the voltage of the “unipolar square wave” form and the measuring channel for the frequency and duration of the pulses, a sine-cosine transformer module and an amplifier module that implements a measuring channel for reproducing synchronous AC voltages, and a discrete input module that implements a measuring channel for time intervals between events.

EFFECT: technical result of the solution consists in the creation of a control and test complex for carrying out DISS checks in semi-automatic mode, which provides increased reliability and reliability of the results of a comprehensive check of the parameters of the equipment being tested in all modes of operation, the possibility of conducting semi-automatic checks.
