Positioning method and device for drive test

摘要

Provided is a positioning method for a drive test, and the method includes: fixed parking sampling points of a testing vehicle in drive test data are determined; location information of the fixed parking sampling points of the testing vehicle is determined according to serving cell identification information of the fixed parking sampling points of the testing vehicle in the drive test data and information of a route matching the drive test data; and location information of a moving sampling point between the fixed parking sampling points of the testing vehicle in the drive test data is determined according to the information of the route. Further provided is a positioning device for a drive test, and by means of the embodiments of the present disclosure, positioning of sampling points in drive test data can be implemented efficiently and accurately, thus having low cost for implementation.

1. A positioning method for a drive test, applied to positioning in a drive test for rail transit, the method comprising:
determining fixed parking sampling points of a testing vehicle in drive test data, wherein the determining fixed parking sampling points of a testing vehicle in drive test data comprising determining sampling points, where radio delays have an amplitude of variation smaller than a pre-set threshold, among consecutive sampling points having same serving cell identification information in drive test data, as a fixed parking sampling points of a testing vehicle, wherein the drive test data further include radio signal delays of the sampling points, and the radio signal delays are a measurement of time taken by radio signals transmitted from a serving cell base station to the testing vehicle, and reflects the distance between the testing vehicle and the serving cell base station; determining location information of the fixed parking sampling points of the testing vehicle according to serving cell identification information of the fixed parking sampling points of the testing vehicle in the drive test data and information of a route matching the drive test data; and determining location information of a moving sampling point between the fixed parking sampling points of the testing vehicle in the drive test data according to the information of the route, wherein the determining location information of the fixed parking sampling points of the testing vehicle in the drive test data according to the information of the route comprises: matching a serving cell identification sequence of fixed parking points in the information of the route with a serving cell identification sequence of the fixed parking sampling points of the testing vehicle in the drive test data, and determining location information of the fixed parking points in the information of the route matching the fixed parking sampling points of the testing vehicle in the drive test data, as the location information of the fixed parking sampling points of the testing vehicle in the drive test data.
