Serial port communication system that can increase communication rate

Abstract

The invention discloses a serial port communication system that can increase a communication rate. The system comprises a signal input module, an interface selection switch, a CPU, a signal temporarystorage module, an interface module and a signal sending module. The output end of the signal input module is connected with the input end of the CPU; the signal output end of the CPU is connected with the input end of the interface selection switch and the input end of the signal temporary storage module; the output ends of the interface selection switch and the signal temporary storage module are connected with the input end of the interface module; the input end of the interface module is connected with the signal sending module; a signal accelerator is arranged in the interface module, aninterface of the signal accelerator is connected with an interface outside the interface module, and the problems that in the prior art, data judgment and sending are conducted through a sending shiftregister circuit and a sending shift register circuit, the process is tedious, the communication speed is low, and the working efficiency is affected are solved.

Description

technical field [0001] The invention relates to a serial port communication system, in particular to a serial port communication system capable of accelerating the communication rate. Background technique [0002] Serial port communication refers to a communication method that transmits data bit by bit through data signal lines, ground lines, control lines, etc. between peripherals and computers. This communication method uses fewer data lines, which can save communication costs in long-distance communication, but its transmission speed is lower than parallel transmission. Therefore, it is especially suitable for long-distance transmission, for those who are not far away from the computer-man-machine exchange equipment and serial storage external equipment such as terminals, printers, logic analyzers, disks, etc. [0003] In the prior art, data is judged and transmitted through the transmission shift register circuit and the transmission shift register circuit, and the proc...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a serial port communication system capable of speeding up the communication rate, and to solve the problem in the prior art that judgment and transmission of data are performed through the sending shift register circuit and the sending shift register circuit. The process is cumbersome, making the communication rate slow and affecting work efficiency. question
