The invention provides a full-electronic direct-current turnout control circuit. The full-electronic direct-current turnout control circuit comprises a relay state acquisition circuit, a fixed detection load circuit, an expression acquisition circuit, an expression control circuit, a short-circuit logic protection circuit, a driving acquisition circuit and a direct-current turnout driving circuit which are connected in sequence, the relay state acquisition circuit acquires state information of a relay; the fixed detection load circuit is used for self-inspection of the current detection unit and the representation control circuit; the representation acquisition circuit performs isolated acquisition on representation current; the indication control circuit is electrically isolated from the input end and the output end and controls the indication state of the direct-current turnout; the short-circuit logic protection circuit adopts AND gate and NAND gate combinational logic and is used for protecting the short circuit of the full-bridge power supply; the driving acquisition circuit is used for performing isolated acquisition on the driving current; the direct-current turnout driving circuit is used for driving a direct-current turnout to be switched. The modularized design of the full-electronic direct-current turnout control circuit enables the maintenance to be simple.
