【摘要】：针对传统设备的串口传输速度慢而且联网困难的特点,提出了使用W5300和单片机C8051F120实现串口和以太网的数据相互转换系统。使用RS232和RS485芯片接收和发送低速的串口数据,使用单片机C8051F120作为核心处理芯片,使用W5300芯片进行以太网数据的发送和接收,设计了具体的硬件电路,使用C语言完成了单片机的程序设计。由于W5300内部集成了TCP/IP协议,所以单片机不需要编写复杂的TCP/IP协议栈。此转换系统能够实现传统设备接入以太网,达到了远程监控的目的。实验结果表明,该转换系统很好的实现了串口数据和以太网数据的相互转换,具有简单可靠、传输效率高、稳定性高、成本低等特点,有一定的实用性和推广价值。
[Abstract]:In view of the slow speed of serial port transmission and the difficulty of networking, a data conversion system between serial port and Ethernet using W5300 and C8051F120 is proposed.Using RS232 and RS485 chip to receive and transmit low-speed serial port data, using single-chip microcomputer C8051F120 as core processing chip, using W5300 chip to send and receive Ethernet data, the specific hardware circuit is designed.C language is used to complete the program design of single-chip computer.Because the TCP/IP protocol is integrated into the W5300, the MCU does not need to write complex TCP/IP protocol stack.This conversion system can realize the traditional equipment access Ethernet, and achieve the purpose of remote monitoring.The experimental results show that the conversion system has the characteristics of simple and reliable, high transmission efficiency, high stability, low cost and so on. It has certain practicability and popularization value.
