Communication Conversion Between UART and Ethernet Based on VxWorks

Most of the existing weapons can not communicate with vessel′s fire control system in naval vessels because of their simple serial communication interfaces.Especially in some weapons, one Ethernet interface needs to communicate with four RS232,which can not be implemented with common converter. Therefore, an embedded conversion system is designed based on VxWorks in the environment of advanced RISC machine(ARM). The system can transfer between universal asynchronous receiver/transmitter(UART) data of four weapons and user datagram protocol(UDP) package of FCS.Software design using real-time task schedule ensures the reliability and real-time of communication.Test results show that the system can meet the demands of reliability and real-time, and can enhance operational capability of weapon system.
