【摘要】：針對(duì)傳統(tǒng)設(shè)備的串口傳輸速度慢而且聯(lián)網(wǎng)困難的特點(diǎn),提出了使用W5300和單片機(jī)C8051F120實(shí)現(xiàn)串口和以太網(wǎng)的數(shù)據(jù)相互轉(zhuǎn)換系統(tǒng)。使用RS232和RS485芯片接收和發(fā)送低速的串口數(shù)據(jù),使用單片機(jī)C8051F120作為核心處理芯片,使用W5300芯片進(jìn)行以太網(wǎng)數(shù)據(jù)的發(fā)送和接收,設(shè)計(jì)了具體的硬件電路,使用C語(yǔ)言完成了單片機(jī)的程序設(shè)計(jì)。由于W5300內(nèi)部集成了TCP/IP協(xié)議,所以單片機(jī)不需要編寫復(fù)雜的TCP/IP協(xié)議棧。此轉(zhuǎn)換系統(tǒng)能夠?qū)崿F(xiàn)傳統(tǒng)設(shè)備接入以太網(wǎng),達(dá)到了遠(yuǎn)程監(jiān)控的目的。實(shí)驗(yàn)結(jié)果表明,該轉(zhuǎn)換系統(tǒng)很好的實(shí)現(xiàn)了串口數(shù)據(jù)和以太網(wǎng)數(shù)據(jù)的相互轉(zhuǎn)換,具有簡(jiǎn)單可靠、傳輸效率高、穩(wěn)定性高、成本低等特點(diǎn),有一定的實(shí)用性和推廣價(jià)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.
