1. A turnout drive system based on a double 2-vote-2 architecture, comprising an interlocking processing subsystem (IPS), an interlocking maintenance station, a turnout drive module and an interlocking maintenance station, wherein the turnout drive module, a full-electronic communication module, and the interlocking processing subsystem (IPS) are connected with each other in order, and the full-electronic communication module is connected to the interlocking maintenance station;
two turnout drive modules, which are mutually redundant, obtain turnout drive commands through the interlocking processing subsystem (IPS) to control drive relays in a turnout to lift and fall for driving the turnout to rotate toward a specified direction, while collecting representation information of the turnout and determining a position of the turnout,
wherein the turnout drive module further comprises a power supply module, a relay control module and an isolation module; when an exception occurs in the power supply module or the relay control module, the isolation module disconnects power from a relay, and
wherein the turnout drive module further comprises a fuse module; when the isolation module fails or an exception affecting safety occurs in a drive system, the fuse module may blow a fuse and guide the drive system to a safe status.
