The invention discloses a train operation safety control method and system based on memory dynamic event triggering, and relates to the technical field of train operation control. Comprises: acquiring a train network control system; determining internal influence factors and external influence factors of the train network control system; a dynamic event triggering mechanism based on memory is designed on the premise of saving network resources and ensuring safe operation of a train network control system; a memory state feedback controller enabling the train network control system to operate safely is obtained by combining a stability theory; and obtaining the gain of a memory state feedback controller and a weight matrix of a dynamic event triggering mechanism, and obtaining the minimum safe transmission time requirement for ensuring the stability of a train network control system according to the longest attack time of the DoS attack, thereby realizing H-infinity guaranteed cost control. According to the invention, through collaborative design of the event triggering weight matrix and the controller gain, balance between network information transmission saving and system performance is realized.
