Crowdsensing-based method for generating temporary speed restriction of train

A crowdsensing-based method for generating a temporary speed restriction of a train, comprising:

• detecting a running track environment based on a crowdsensing technology, and intelligently fusing multi-sensing-source sensing results comprising trains, drivers or scheduling personnel, unmanned aerial vehicles and satellite remote sensing by an intelligent fusion unit for the multi-sensing-source sensing results, wherein the intelligent fusion unit adopts a temporal-spatial two-stage boosting fusion architecture:
• a first-stage architecture employs LightGBM to perform temporal residual fitting on vehicle-end slip data and outputs a microscopic risk index, and a second-stage architecture adopts AdaBoost to perform weighted fusion on the microscopic risk index and the multi-sensing-source sensing results, after fusion, performing a comprehensive judgment and outputting a speed restriction request, wherein the speed restriction request comprises a requested speed restriction value, a requested speed restriction area, a speed restriction object vehicle type, and a speed restriction time range;
• and the intelligent fusion unit for the multi-sensing-source sensing results comprises a plurality of differentiated independent computing units, which respectively generate fusion results by adopting differentiated fusion algorithms, and then integrates the fusion results of each independent computing unit;
• if any independent computing unit determines that the speed restriction request needs to be generated, the unit as a whole shall determine to generate the speed restriction request;
• generating, by a temporary speed restriction server, a temporary speed restriction command based on a received speed restriction request, and sending the temporary speed restriction command to train control center equipment or radio block center equipment, a jurisdiction scope of which covers a requested speed restriction zone, wherein the temporary speed restriction command comprises a speed restriction zone and a speed restriction value;
• and
• automatically issuing, by the train control center equipment or the radio block center equipment, the temporary speed restriction command to a train entering the speed restriction zone.
