[0039] Step S11: Create an IoT access gateway for the in-vehicle terminal of the new energy vehicle, and receive the data reported by the in-vehicle terminal of the new energy vehicle. The data reporting frequency is within 30 seconds;

[0040] Step S12: Parse the data reported by the in-vehicle terminal of the new energy vehicle according to the national standard GB / T32960.3-2016 "Technical Specification for Electric Vehicle Remote Service and Management System - Part 3: Communication Protocol and Data Format" to obtain the vehicle location data, including the positioning status, longitude, latitude, and data time;

[0041] Step S13: Clean the parsed data to eliminate invalid or other abnormal data in the positioning status.

[0042] Step S2: Use the reverse geocoding of the GIS geographic information system to convert the vehicle location data to obtain the list of the nearest roads. Specifically, perform reverse geocoding on the longitude and latitude in the vehicle location data to obtain the list of the nearest roads;

[0043] In this example, the specific content of step S2 is as follows:

[0044] Use the reverse geocoding interface of the GIS geographic information system, input parameters such as longitude, latitude, specified radius distance, and road level, to obtain the list of roads near the vehicle location point, including the road name and the distance from the road to the vehicle location.

[0045] Step S3: Calculate the distance from each obtained road to the vehicle location point to get the distance score of each road to the vehicle location, and store it. Specifically, calculate the distance score according to the length of the distance from the road to the vehicle location;

[0047] For the list of roads obtained in step S2, calculate the distance score of each road according to the set distance score calculation rule; store the calculated road name and its distance score, and each road is stored as a record. For example, the distance score calculation rule is set as: The road within 1000 meters (configurable) of the longitude and latitude of the vehicle location point is valid, and the distance score calculation formula is: S n = (1000 - the actual distance from the location to the road) / 1000, to obtain the distance score S of each location data from the nearby 1000-meter road n, where n is the number of valid roads.

[0048] Step S4: Statistically sum up the distance scores of each road within a specified period as the heat value of the road traveled by the new energy vehicle and display it. That is, group by road name, sum up the distance scores obtained at each moment of each road within the specified period, and obtain the total score K = ∑S of each road. n , and the score K is the heat value of the road traveled by the vehicle.

Compared with the traditional site selection method, it uses quantitative indicators instead of manual judgment, avoiding the unscientific nature brought by subjective human judgment. The present invention is easy to understand and operate, and has strong operability. Except for the difference in obtaining vehicle position data involved in this method, other steps can also be extended to fuel vehicles. By calculating the heat value of the road traveled by the vehicle, it provides data reference for the site selection of gas stations and maintenance points for fuel vehicles.
