Liuyang River model train control room a simulation system consists of two subsystems a, microcomputer interlocking and sandbox demo system. b, decentralized self-scheduling exercise centralized system (CTC) 2, features an overview of a, computer interlocking system: with computer interlocking system and field station display graphics, fully consistent graphical simulation display station, participants linked by computer locking system in normal and non-normal approach situations, receiving trains, shunting operations and various fault conditions such as operating under emergency drills to improve student's proficiency level and emergency purposes, by bus services Terminal hair centralized command scheduling, centralized control. b locomotive control system: control of multiple devices via a wireless transmitter locomotives to run on the sand table, depending on the signal state to the command station locomotive forward, backward, acceleration and deceleration, parking and analog automatic train stop. c, CTC Operations terminal system: information collection function; report points automatically, manual reporting points and points to modify the function; train number management; scheduling commands to sign and print; stages of the project and receipt printing; traffic log management; Now car management. d, CTC autonomic systems: sending and receiving functions dispatch plan; then sent directly to the operating instructions; train trips tracking; operational data upload function; send commands to the computer operating interlocking simulation system. Traction motors and gears (1:1 demo model) High transparent acrylic shell, the internal structure is clearly visible, the use of aluminum, copper, high-strength materials, electric lighting demonstration.
