Description

one

The invention relates to telecommunications and can be used to estimate and monitor equivalent load parameters in networks and information distribution systems.

The purpose of the invention is to improve the accuracy of control.

The drawing shows a device for implementing the proposed method.

A device that implements the method includes a sensor 1 of the line to be monitored, a first linear integrator 2, a quadratic integrator 3, an amplitude detector A, an inverter 5, a second linear integrator 6, and a block 7 of calculations.

The essence of the proposed method is that over a period of time T determine the result of linear (R) and quadratic (M) integration of the signal about the state of the monitored line, measure the maximum value (Pr) of this signal and the probability (Rd) that This signal is equal to zero, and the equivalent load parameters — the intensity of the equivalent load on the controlled line (A) „. The intensity of the equivalent load on the equivalent beam of channels (Hell) and the number of equivalent channels (n) is determined by solving the system equation Yeni
