The EDPF-NT system is a decentralized control system designed and developed based on the advanced ideas of many similar systems in the world, and combined with the national conditions of China. The EDPF-NT system is based on network communication, with a “station” implemented for functionality and objects as the basic unit. A specially designed distributed dynamic real-time database is used to manage all the data required for the operation of the system distributed at each station.
The system network can adopt star, circular, or tree structures to achieve complete physical and logical redundancy, achieving multiple 2X2 redundancy; Network service software and network hardware work together to achieve communication between stations and achieve global information sharing through distributed real-time databases.
The division of each station in the system is based on the principle of relative autonomy of functions, and different functions are implemented by different stations. The EDPF-NT system consists of seven stations: ENG station, OPR station, DPU station, HSR station, LOG station, CAC station, and GATEWAY station.
