Research And Design Of Embedded Multi Serial Port Server Based On STM32

With the rapid development of natural science and the popularization of electronic science and technology,intelligent electronic science equipment has become indispensable to People's Daily life and daily life.When the popularization and development of computer become faster and more mature,the speed of network transmission becomes more and more important.At this time network serial port action is reflected.However,due to the restriction of environment in the industrial field,it is difficult to realize the long-distance serial communication.In addition,serial communication itself has many limitations to solve the problem.For example,whether the transmission distance is reliable or the transmission speed is poor,it is not possible to achieve reliable communication requirements between a large number of serial ports and remote hosts.It is precisely because of these problems that it limits its development to more areas.There is a technical bottleneck,and we need to find other ways to get the desired effect.In order to effectively solve the problem of serial port communication,a stable and secure serial communication between a large number of serial ports and one or more remote hosts is realized.Then,the multi-serial port server that enables the serial port devices to communicate with each other has emerged.Its function is to realize the transmission of data in remote and even remote distance,and ensure the security and rapidity of transmission;The monitoring and control of serial devices only needs to be operated by network.In constantly discover and explore,considering the quickness of embedded system on data processing and system itself superior to clipping,can make a serial port server on data processing can be more rapid,efficient execution,this paper designed a based on the STM32 embedded serial server.The main contents of this paper are as follows:1.Brief introduction to the development of serial port server at home and abroad.2.Design the serial port server as a whole,and give several application schemes,and then understand the relevant system protocols.3.Analyze the serial port server as a whole,including the required functions and devices to be used.4.Set up the hardware platform of the serial port server,and explain the high-performance processor STM32F103RCT6 and other relevant modules of the ARM cortex-m3 architecture used by it.5.Understand the writing platform of the software,and write the program to realize the corresponding functions through the functions required by the serial port server;Both transparent and protocol transfer.6.Finally,the test results and relevant conclusions of the system need to be given.
