REAL-TIME DYNAMIC CONTROL METHOD FOR TEMPORARY SPEED-LIMIT REVELATION

WIPO Patent Application WO/2024/017422

A2

Provided in the present invention is a real-time dynamic control method for temporary speed-limit revelation. The method comprises: when the actual speed of a train is 0 km/h, performing pre-determination calculation of temporary speed-limit revelation according to a given speed of 1 km/h, so as to realize a pre-determination reminder of temporary speed-limit revelation in the front; calculating an expected travelling distance of the train according to the current speed of the train and the time difference between the current time and a revelation control start time; and comparing an expected mileage of the train with a start mileage of the temporary speed-limit revelation, so as to confirm a control start point of the temporary speed-limit revelation, thereby realizing the dynamic control and accurate pre-determination of the temporary speed-limit revelation. The present invention can determine, when the actual speed of a train is 0 km/h, that there is temporary speed-limit revelation in the front, and realizes the real-time dynamic control of the temporary speed-limit revelation, such that accurate speed-limit pre-determination can be performed.
