Patent Searching and Data


Title:
SECTIONAL SPEED LIMIT VALUE OBTAINING METHOD AND DEVICE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/029199
Kind Code:
A1
Abstract:
Provided in the present application are a regional speed limit value obtaining method and device and a terminal device, wherein the regional speed limit value obtaining method comprises: mapping a track section on an operation line of a train in electronic map data to a coordinate system; respectively storing the speed limit data of a temporary speed limit and a fixed speed limit of the train in the track section in a temporary speed limit information list and a fixed speed limit information list in a one-to-one correspondence mode according to the coordinates of the track section in the coordinate system; combining the speed limit data in the temporary speed limit information list and the fixed speed limit information list to obtain a strictest speed limit list of the train; and searching the strictest speed limit list to obtain a strictest speed limit value of the section corresponding to a real-time coordinate position of the train. According to the present application, multiple pieces of temporary speed limit data are combined at one time into the strictest speed limit list, and therefore, the logic processing of the query of the electronic map data is simplified, and program efficiency can be improved.
