Abstract

Disclosed are a method and device for increasing the adaptability of light intensity, which relate to the field of photoelectric communications. The method comprises: providing several stages of load resistors in the device, the device collecting voltage values, calculating the average value of all the collected voltage values when a preset number of voltage values which meet the requirements are collected, setting a voltage according to the average value and judging whether the set voltage meets preset requirements; and if yes, collecting data according to the set voltage; otherwise switching a load resistor according to a preset rule, wherein the load voltage may affect the voltage collection. The present invention has the beneficial effects of: improving the adaptability of a screen to light intensity during optical signal collection, and at the same time being able to reduce the error rate.

First claim

The invention claimed is:

1. A method for processing an optical signal, comprising a sampling process and a converting process, wherein the sampling process comprises steps from S 1 to S 5 , and the converting process comprise steps from S 6 to S 8 , and steps S 1 to S 8 comprising:
S 1 : sampling, by a sampling module, an electric signal to obtain a sampling result and store the sampling result to a cache;
S 2 : judging, by the sampling module, whether the number of samplin…
