Test method of location system, control terminal and device with storage function

Abstract

The present invention discloses a test method of a location system, a control terminal and a device with a storage function. The method comprises: a control terminal is connected with a test terminal and a reference terminal, and the test terminal is moved along the same path as the reference terminal; the control terminal receives position information from the test terminal and the reference terminal; and the position information difference of the test terminal and the reference terminal is employed to determine whether the position of the test terminal is abnormal or not. According to the mode, the test method of the location system, the control terminal and the device with the storage function can monitor whether the location of the test terminal has drifting abnormality or not in real time to allow researchers to immediately combine the field road condition to perform analysis of the drifting abnormality.

Description

technical field [0001] The invention relates to the field of positioning systems, in particular to a testing method for a mobile terminal positioning system, a control terminal, and a device with a storage function. Background technique [0002] Currently, a GPS (Global Positioning System, Global Positioning System) function has become a standard configuration of a mobile terminal. In the R&D testing stage, it is necessary to conduct real-time outdoor driving navigation tests on the GPS function to ensure the accuracy of positioning. The usual test mode is: the test terminal and the reference terminal use the built-in test program of the mobile terminal to conduct an outdoor driving navigation test, grab the log file after the test, import Google Maps and other software offline, obtain the test terminal route and the reference terminal route, and then compare them . This test method is not real-time due to inconvenient viewing of the terminal screen and too many test termi...

AI Technical Summary

Problems solved by technology

This test method is not real-time due to inconvenient viewing of the terminal screen and too many test terminals in the on-site test. It is impossible to obtain whether there is current drift in real time, and it cannot be ruled out whether it is due to road conditions and environmental problems, and it is impossible to focus on the intersection test Multiple tests at different points will also cause certain difficulties for R&D and analysis of drift problems, resulting in an increase in the number of drive tests and the cost of drive tests
