Method and system for protecting data information of power amplifier

Abstract

The invention provides a method for protecting data information of a power amplifier, comprising the steps: respectively storing the data information in a first group of storage units; computing checking codes which correspond to the data information and respectively storing the checking codes in a second group of storage units, wherein the second group of storage units corresponds to the first group of storage units; reading current data information from any storage unit of the first group of storage units when the power amplifier is electrified again; computing the current checking code which corresponds to the current data information and comparing the current checking code with the checking code in the corresponding storage unit in the second group of storage units. The provided system comprises a computing module, the first group of storage units, the second group of storage units and a comparing module. The invention effectively protects data by a repeated storage method of the data, reduces the failure rate of the data and enhances the accuracy of the data by checking operation.

Description

technical field [0001] The present invention relates to a method and system for protecting data information, in particular to a method and system for protecting data information of a power amplifier. Background technique [0002] Power amplifiers are generally divided into audio power amplifiers and radio frequency power amplifiers. The audio power amplifier is to amplify the weaker signal input by the audio source equipment, and then generate a large enough current to drive the speaker to reproduce the sound; while the radio frequency power amplifier is often used in the final stage of the transmitter to convert the high-frequency modulated signal Power amplification is carried out to meet the requirements of sending power. No matter what kind of power amplifier it is, after they are used in the actual system, they will be debugged in order to achieve the best working condition. The core of their work is stability and reliability, so the operating parameters of the power ...

Problems solved by technology

[0003] However, because some power amplifiers are often placed outdoors, they are often affected by lightning and many strong electromagnetic interferences from the outside world. These electromagnetic interferences may change some or all of the data in the stored data information, making the power amplifier operate according to these data. error occurs when

At the same time, when the operating program of the power amplifier is wrong or the working voltage is unstable, the stored data information may be changed.

The stored data information is often only stored in one copy, so once the data is modified, it cannot be restored

So the power amplifier doesn't work properly
