The invention relates to the technical field of derailment detection, and discloses an underground tramcar derailment detection method and system, and the method comprises the steps: collecting the position information of underground to-be-monitored nodes, constructing an underground position network, and generating a redundant node connected graph according to the distances of different to-be-monitored nodes; generating an energy-saving robust routing strategy, determining an optimal monitoring data transmission path of the node to be monitored by using the energy-saving robust routing strategy, and performing underground monitoring data transmission; and forming an optimal underground tramcar derailment detection model according to the model parameters obtained by optimization solution, and carrying out underground tramcar derailment detection. According to the method, a next hop transmission path node is selected in combination with the sensing radius and the mutual distance of the sensor, the optimal monitoring data transmission path with the fastest transmission speed and the low interference degree is obtained, and effective feature information is extracted from historical operation data to carry out fusion operation on current operation data; and obtaining a probability value of derailment of the underground tramcar at the current moment, and realizing derailment detection of the tramcar.
