The invention provides an SCADE-oriented automatic script generation method. The method comprises the following steps of: firstly simulating system data, and obtaining information of a regional controller and a central controller from a database, wherein when data of the regional controller is simulated, data is dynamically generated according to a real communication period; simulating equipment data of passing stations, simulating a station map, and obtaining data of tracks through which a train passes according to dynamic movement of the train on the tracks; and finally, simulating train data, establishing a single-particle train model, and simulating the train to obtain state information of the train. According to the method provided by the invention, the script compilation is converted from the traditional artificial design to automatic generation, so that plenty of repeated work of the testers can be effectively decreased, the artificial script design is avoided, the working efficiency is improved, the script generation periods are set at a millisecond level and the dynamic change requirements of input data in each period are satisfied at the same time.
