The Railway Digital Radio Train Dispatch (DRTD) system is a new-generation digitalized train dispatch communication system. The company has developed a railway-specific DRTD digital optical fiber repeater system that incorporates digital frequency conversion technology, multi-channel fusion technology, and a proprietary ring redundancy algorithm tailored for railway applications.
This system simultaneously supports both 450MHz analog and 400MHz digital train dispatch communications. It is compatible with the 450MHz Type B/C analog standards as well as the digital DRTD standard. Furthermore, it supports multi-standard Push-to-Talk (PTT) adaptive communication, as well as "large triangle" and "small triangle" communication functions. This effectively resolves issues such as redundant investment and duplicate construction and maintenance during the transition from 450MHz analog to 400MHz digital communications.
Additionally, the DRTD repeater system features comprehensive environmental and power data monitoring capabilities, including support for dual power supply monitoring, lightning protection cabinet monitoring, and individual battery cell monitoring.
