Communication adapter with error correction processing function and application thereof

Abstract

A communication adapter with error correction processing function and the application thereof are disclosed. The adapter comprises a DSP and corresponding power source control module, an active crystal oscillator module and a watchdog module; it is characterized in: the serial reception interface and the serial transmission interface of the DSP are respectively connected with a level conversion module and a RS232 interface; the RS 232 interfaces are respectively connected between the communication adapter, and the external transmission terminal and the external reception terminal; the generalpurpose digital quantity input and output port of the DSP are respectively provided with a reception state indication module, a receiving end baud rate display module, a transmission state indicationmodule, a transmitting end baud rate display module, an error correction processing digit number indication module, and a button module used for setting the baud rate, verification mode and error correction processing digit number of the DSP serial reception interface and the serial transmission interface. The invention can perform the communication between the communication terminals with different communication rates. The invention is used for performing the communication between the communication terminals with different communication rates.

Description

technical field [0001] The invention relates to a data transmission device, more specifically a communication adapter with error correction processing function, which can be used for data transmission between communication terminals with long distance, large interference, and different baud rates or check digits. transmission. Background technique [0002] With the development of information technology and computer technology, various communication devices and terminals using serial communication have become very popular. Since different terminals have different communication rates for collecting and transmitting data, there is a problem of how to achieve different communication rates. Communication problems between communication devices. The multifunctional communication adapter acts as a bridge between various devices. [0003] In addition, with the rapid development of computer and communication technology, the business volume of computer network data transmission is in...

AI Technical Summary

Problems solved by technology

[0005] 1. It can only solve the data transmission between a single two different communication rates, and cannot realize free switching between multiple different communication rates

[0006] 2. Does not have error correction processing function, only suitable for short-distance data transmission

[0007] 3. The current error correction processing method, regardless of the length of the data, only uses one form of BCH code for error correction, and cannot select the appropriate form of BCH code according to the data length, and the error correction processing efficiency is low
