Turnout intelligent diagnosis method based on relay interlocking

The invention discloses a turnout intelligent diagnosis method based on relay interlocking, which comprises the following steps: receiving and analyzing turnout representation voltage, a turnout action curve and a turnout relay state message, and carrying out structured processing on the analyzed information and storing the information in a database; analyzing the state of the 1DQJ in the database, and executing a dynamic diagnosis step or a static diagnosis step according to whether the 1DQJ is sucked up or not; wherein in the static diagnosis step, data are read regularly, positioning static diagnosis logic is executed when the 1DQJ state is falling and the DBJ state is suction, and the positioning static diagnosis logic performs diagnosis according to a fixed table direct current voltage value and an alternating current voltage value; when the 1DQJ state is a falling state and the FBJ state is a sucking state, anti-bit static diagnosis logic is entered, and the anti-bit static diagnosis logic carries out d
