| Abstract: | This paper presents a new railway field monitoring system with a embedded system as its core. Using low voltage power line carrier for bus communication, it realizes long-distance feeding and data transmission. It is also introduced that general system design, software and hardware designs of each module. Moreover, communication protocol is defined to realize overtime retransmitting, error-check retransmitting, broadcasting, point-point communication. |
