Abstract： A mine-used multi-function serial signal converter is introduced. This converter is based on Ethernet. The core of this design is embedded microprocessor STM32F107VCT6. Embedded operation system μC/OS-II is transplanted into this converter, and light-weight Internet protocal (LwIP) stack is also embedded to realize mutual conversion of serial signals such as meter bus (M-Bus) signal, RS485 signal, RS232 signal and Ethernet signal. Interconnection between all kinds of monitoring system interfaces under coal mine can be formed easily, which can solve compatibility problem between monitoring system and communication system and improve overall performance of safety monitoring system. The designed multi-function serial signal converter is of great value for application, which is worthy to be popularized in coal mine safety production.
