In order to solve the present problem of lacking of railway signal outdoor information monitoring technology, this research proposes a design program of outdoor information monitoring and communication unit. First, we introduce the characteristics of power line carrier communication and adopt the Hoffman coding as encoding mode. Second, the bus-powered is used as transmission mode and the content is transmitted in “data packet heart packet”. Meanwhile, this monitoring and communication unit realizes the functions of collecting, recording, and uploading the information of the railway signal outdoor equipment. Finally, this research sets the ZPW-2000 track circuit as a case study to test and verify the function’s real-time and accuracy, and the result indicates that the unit meets the basic requirements. Therefore, this research can not only provide the basis for fault diagnosis and alarm analysis, but also can reduce the manpower and time cost of railway signal outdoor equipment maintenance.
