Embodiment Construction

[0021] In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

[0022] More and more motion state detection is used in navigation scenarios to assist navigation according to the motion state. At present, the commonly used motion state detection methods in related technologies are to use inertial sensors to detect the user's motion state, or to use RFID tags. The array and the locator jointly detect the motion state, but the above detection method has the problem that the detection accuracy is not high, so that the detected motion state is not accurate enough.

[0023] Based on this, the inventor proposes a motion state detection method, device, storage medium, and electronic device provided in the present application, in wh...

Abstract

The invention discloses a motion state detection method and device and electronic equipment, and relates to the technical field of map navigation. The method comprises the steps of: acquiring satellite broadcast data received by receiving equipment and a data receiving moment when the satellite broadcast data are received, the satellite broadcast data comprising navigation ephemeris and time information of a satellite; obtaining the satellite position and the satellite speed of the satellite at the data receiving moment according to the navigation ephemeris and the time information; acquiringequipment information of the receiving equipment at the data receiving moment and a Doppler observation value of the satellite at the data receiving moment; and obtaining the motion state of the receiving equipment at the data receiving moment according to the equipment information, the Doppler observation value, the satellite position and the satellite speed. Therefore, the accuracy of motion state judgment can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of map navigation, and more particularly, to a motion state detection method, device, electronic device and storage medium. Background technique [0002] With the rapid development of electronic maps and mobile Internet technologies, more and more people will use navigation devices that store electronic map navigation software or have map navigation functions in their daily travel, so that they can drive, ride or walk while driving, riding or walking. , When you are not familiar with road conditions or intend to know the traffic information of road vehicles, use the navigation device for map navigation. [0003] In the process of map navigation, the navigation device will determine the user's motion state, such as walking, running, cycling, or driving. low level issue. SUMMARY OF THE INVENTION [0004] In view of this, the present application proposes a motion state detection method, device, el...
