2.HJ05A Enterprise Station Centralized Dispatching System is a set of computer integrated monitoring system used by dispatchers to control and supervise signal equipment and train operation status in the command center to realize centralized control of multiple stations. Based on the railway signal computer interlocking system and the railway logistics management system, the system further extends the functions of the centralized station dispatching system, generates shunting plans by dragging or intelligent triggering, automatically prearranges the signals and executes the plans, completes the management and control integration of plan preparation and signal opening, creates conditions for the post merger of watchman and signalman, and realizes the purpose of reducing staff and increasing efficiency of the enterprise.
The system is composed of the control center subsystem and each station subsystem, and each subsystem is connected into a control network through the network transmission channel. The whole system adopts LAN based on TCP/IP protocol and computerized distributed system structure. The dispatching centralized machine and communication front-end machine adopt dual machine hot standby redundancy setting. The transmission channel between the main nodes of the network adopts the dual channel design of main and standby to ensure the security and reliability of the system. The system has complex technology and high safety requirements, which can save a lot of human resources and greatly promote the reduction of production safety accident rate and improvement of operation efficiency. It provides technical support for the first level dispatching centralization, simplifies posts and improves efficiency, and provides the basis for unmanned railway transportation.
