摘要
为实现以太网接口与RS422目标设备之间的数据透明互传功能,设计了自适应数传速度的网口串口数据互传工装。该工装以STM32F407ZGT6单片机作为主控制单元,设计了RS422接口电路。实验结果证明,该工装能够实现网口与串口双向互传,串口波特率能够达到3 Mb/s,13小时数据收发不丢包,具有较高的性能和可靠性。
In order to realize the data transparent mutual transmission function between the Ethernet network port and the RS422 target device, a network port to serial port tooling is designed.The tooling uses STM32 F407 ZGT6 microcontroller as the main controller, designs RS422 interface circuit.The test results prove that the device can realize two-way mutual transmission between the network port and the serial port, the baud rate of the serial port can reach 3 Mb/s, and the data is sent and received within 13 hours without packet loss, and has strong working performance and reliability.
