介绍了一种以STM32互连型系列微控制器STM32F107VCT6为核心的矿用多功能以太网串口信号转换器。该转换器移植了μC/OS-II嵌入式操作系统,并嵌入了LwIP协议栈,通过软硬件的设计实现了以太网信号与M-Bus信号、RS485信号与RS232信号的相互转换,使煤矿井下各种监控设备接口之间的互联更加便捷。该转换器有效解决了各种监控系统和通信系统之间的兼容性问题,提高了安全监控系统的整体性能,具有很好的应用价值,值得在煤矿安全生产中推广使用。
This paper introduces a mining multifunction Ethernet serial port signal converter based on the STM32 interconnection series microcontroller STM32F107VCT6. This converter transplants the μC / OS-II embedded operating system and embeds the LwIP protocol stack. Through the design of hardware and software, it realizes the mutual conversion of Ethernet signal, M-Bus signal, RS485 signal and RS232 signal, A variety of monitoring equipment interface between the more convenient. The converter effectively solves the compatibility problems between various monitoring and control systems and communication systems, improves the overall performance of the safety monitoring system, has good application value and is worthy of promotion in coal mine safety production.
