The invention discloses a railway train operation safety situation judgment method and device with multi-information integrated. The train operation method comprises the following steps that first, wind characteristic parameters and road condition information are collected; second, a train aerodynamic force and road situation model and a train aerodynamic force, wind characteristic parameter and train speed model are built; third, a train turnover stabilizing model is built; fourth, the speed limit for a train to keep safe operation is determined according to the train turnover stabilizing model. According to railway train operation safety situation judgment method and device with multi-information integrated, by comprehensively taking comprehensive information such as the wind speed, the wind direction and the train model into consideration, the relational expression between multiple types of information is built. On the basis of the relational expression, the speed limit of the train in safe operation is obtained, and therefore operation of the train can be guided.
Description
technical field [0001] The present invention relates to the technical field of rail transit safety, in particular to a method and device for judging the safety situation of railway traffic with fusion of multiple information. Background technique [0002] Railway transportation is a mode of transportation that has developed rapidly and is widely used in modern times. Compared with air transportation, river transportation, sea transportation, etc., it has a higher safety factor and a larger carrying capacity, which not only facilitates people's travel, but also drives social progress and development. [0003] However, under relatively severe weather conditions, such as high winds, low temperature, thunderstorms, etc., certain accidents may also occur during the running of the train. Among them, the impact on the operation of the train is more common and huge especially in the windy weather environment. The reason is that when the wind speed and wind direction meet certain c...
