Frequency device compensation method, device and system and computer readable storage medium

Abstract

The invention discloses a frequency device compensation method, device and system and a computer readable storage medium, and belongs to the technical field of communication. The method comprises acquiring a clock signal output by a frequency compensation sensor as a first predictive variable; acquiring a variable output by a predictive variable sensor and related to frequency fluctuation as a second predictive variable; compensating a frequency device according to the first predictive variable and the second predictive variable. By replacing a temperature sensor by a frequency sensor, and providing the predictive variable associated with the frequency fluctuation, the method improves the accuracy and stability of frequency compensation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a frequency device compensation method, device, system and computer-readable storage medium. Background technique [0002] Almost all electronic equipment, communication equipment, and automatic control equipment need a clock to ensure the normal operation of the system. The clock signals of these equipment basically come from frequency devices. In order to improve the accuracy of the clock, some systems use a phase-locked loop to track an external reference clock. The system has different requirements on the stability of the clock, and different levels of frequency devices and external reference clocks will be selected. Changes in the external environment will affect the stability of the frequency device, resulting in clock instability; the loss of the reference source will also lead to a decline in clock performance. When the reference clock is lost, or for a pe...

Problems solved by technology

There are two main reasons for the shortcomings of the existing technology: first, the temperature resolution is not high and the cost is high; second, other environmental factors cannot be compensated by temperature or time data, that is, the problem of missing predictor variables

The temperature predictor usually uses a temperature sensor chip to collect data. At present, the high-precision temperature sensor on the market has a resolution of 0.01 degrees, which costs about 3 US dollars, and the cost is high.

In addition, the fluctuation of the working power supply, or the frequency fluctuation caused by external influences such as vibration and shock, the commonly used temperature variables cannot be compensated
