Abstract

The invention discloses a digital train tail master control unit. A core processor of the digital train tail master control unit comprises a clock position instruction sheet mapping table, an external information input module, a fault diagnosis module, a data processing module, a data transmission module and a data collecting module, wherein a 450MHz transmission module comprises a 450MHz analogue-to-digital power amplifier module, a data encryption and decryption module, an output interface module, a modulation algorithm module and a coherent demodulation module; the core processor is connected with the digital 450MHz transmission module, a GSM-R (global system of mobile communication for railways) transmission module, a clock locating information collector, an operation information discharge and download module, an auxiliary maintenance module and an external interface module through a standardized interface. By adopting the digital train tail master control unit, the problems of weak anti-jamming capability, wide occupied bandwidth and the like of the existing train tail system can be avoided; the comprehensive utilization rate of the system is improved; a good information platform is provided for informational, digital and intelligent development and construction of railways; meanwhile, the safety of trains in running is improved; a digital train tail system in true sense is achieved.

Description

technical field [0001] The invention relates to a digital train tail main control unit, which is arranged in a locomotive and is specially used for digitally controlling a safety protection device at the train tail, and belongs to the technical field of train braking. Background technique [0002] At present, the safety protection devices at the tail of existing freight trains in my country adopt 450MHz analog system, which has weak anti-interference ability, difficult to realize business expansion, and inability to establish a train monitoring system in transit. In addition, according to relevant industrial policies, the analog system adopts low frequency band The device system will face disabling or transfer. Contents of the invention [0003] The purpose of the present invention is to provide a digital train tail main control unit, which can realize real-time detection of the in-transit operation status information of the railway train braking control system, improve the...
