Abstract

The invention provides a vehicle thermodynamic diagram construction method, device and system, and the method comprises the steps: enabling the received GPS data of a vehicle to be converted into one-dimensional character strings with two or more kinds of precision through a GeoHash algorithm, and enabling the one-dimensional character strings to be used for describing the latitude and longitude position information of the vehicle; According to a preset time interval, aggregating the same one-dimensional character strings in the time interval into a record in a database table; when a query instruction is received, screening out a group of records matched with the query instruction from all the records; And generating a vehicle thermodynamic diagram matched with the time information and thegeographic area information according to a group of screened records. According to the vehicle thermodynamic diagram generation method and device, the vehicle thermodynamic diagram is generated according to the aggregated data obtained after the GPS data is processed in advance, and compared with the mode that the thermodynamic diagram is obtained according to the original GPS data, the calculated amount is reduced, so that the vehicle thermodynamic diagram generation efficiency is improved, and the query efficiency is improved.

Description

technical field [0001] The present application relates to the field of transportation technology, in particular to a method, device and system for constructing a vehicle thermal map. Background technique [0002] Vehicle heat map refers to a diagram showing the density of vehicles in a geographical area in a special highlighted form. Usually, a vehicle heat map is drawn in the form of contour lines on an electronic map, and different colors are used in the closed graph to represent different For example, the darker the color, the more vehicles, and the lighter the color, the fewer vehicles, which can provide a basis for traffic monitoring and urban road network planning. [0003] The vehicle heat map includes a real-time heat map and a historical time interval heat map. The historical time interval heat map refers to a heat map of a certain period of time in the past, such as hourly, daily, weekly, and monthly heat maps. In the prior art, the real-time vehicle thermal map i...
