    The invention provides a steel rail state monitoring method and system based on data external circulation and monitoring internal circulation, and the method comprises the steps: obtaining line basic parameters of data external circulation for a pre-monitored steel rail, carrying out the fitting of the line basic parameters to obtain a basic state model, and obtaining a steel rail loss monitoring result of monitoring internal circulation, and carrying out the fitting to obtain a steel rail monitoring state model; combining the basic parameters of the line and the monitoring result of the steel rail loss to obtain a steel rail service state model through double-loop fitting, and obtaining the service state of the pre-monitored steel rail according to the basic state model for the line of which the steel rail service life is greater than the overhaul service life; for the line with the steel rail service life smaller than or equal to the overhaul life, according to the steel rail service state model, the predicted time node of the main fault position of the predicted line steel rail and the corresponding fault type are obtained, and then preventive maintenance and advanced key monitoring are conducted on the pre-monitored steel rail. The system can carry out preventive maintenance and advanced key monitoring on the pre-monitored steel rail, consumes less manpower, does not affect the normal operation of a train, and is high in efficiency.
