Manufacturing method of baud rate self-adaptive serial communication repeater

Abstract

The invention provides a manufacturing method of a baud rate self-adaptive serial communication repeater, belonging to the field of electronic communication, and particularly relating to the manufacturing method of the baud rate self-adaptive serial communication repeater. The method adopts a data processing mode of connecting a first microcontroller and a second microcontroller with a double-port RAM so as to connect the first microcontroller with a first baud rate self-adaptive serial communication device through a signal line, and connect the second microcontroller with a second baud rate self-adaptive serial communication device through the signal line. The interior modules of the first baud rate self-adaptive serial communication device and the second baud rate adaptive serial communication device comprises a baud rate self-adaptive generator, a signal converter, a parallel-serial data receiving shifter, a serial-parallel data sending shifter, logic and gate and logic and nor gate which are all manufactured by adopting programming devices. The repeater has the characteristics of novel structure, stable communication, high speed, automatic recognition of data speed on a bus, double-port RAM as a shared memory, flexible and convenient interface and easy control; in addition, the repeater has good maintainability and expansibility and low cost.

Description

technical field [0001] The invention relates to a manufacturing method of a baud rate adaptive serial communication repeater, belonging to the field of electronic communication, in particular to a manufacturing method of a baud rate adaptive communication repeater. Background technique [0002] Serial communication has a simple structure and low hardware overhead, and is currently the most widely used communication method. With the expansion of the serial bus network area, it is difficult to directly transmit data between two nodes to meet the requirements of long-distance communication. The repeater is a relay station that extends the communication distance of the serial bus. Its communication efficiency and reliability of communication directly affect the communication capability of the serial bus. The traditional serial bus repeater based on a single microcontroller is difficult to meet the needs of a large amount of data. Therefore, it is very important to design a repe...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the transmission distance of serial communication is short, after adopting the traditional repeater, although the problem of communication distance is solved, the transmission data speed and the batch of data on the bus have certain restrictions, and It is necessary to manually set the communication baud rate of the repeater
