Embodiment Construction

[0037] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0038] Please refer to figure 1 As shown, Embodiment 1 of the present invention provides a drift processing method for a GPS device based on a gravity sensor, including:

[0039] Step S1, judging whether the GPS device is in a motion state or a static state at the current positioning point;

[0040] Step S2, when the GPS device is in motion, if its speed at the current positioning point is less than or equal to the first speed threshold or greater than or equal to the second speed threshold, it is determined that the GPS device has drifted in speed, and its speed at the current positioning point is abandoned. GPS data upload and / or mileage accumulation;

[0041] Step S3, when the GPS device is in a stationary state, set its longitude, latitude and mileage value at the current positioning point to be equal to the longitude, latitude and mileage value of...

Abstract

The invention provides a GPS device based on a gravity sensor and a drifting processing method thereof. The drifting situation can be effectively shielded, and the positioning accuracy can be improved. The drifting processing method comprises the steps that firstly, whether the GPS device is in a moving state or in a stationary state at the current positioning point is judged; secondly, when the GPS device is in the moving state, if the speed of the GPS device at the current positioning point is smaller than or equal to a first speed threshold value or larger than or equal to a second speed threshold value, it is judged that speed drifting occurs on the GPS device, GPS data uploading and / or mileage accumulation of the GPS device at the current positioning point are / is abandoned; thirdly, when the GPS device is in the stationary state, the longitude, latitude and mileage of the GPS device at the current positioning point are set to be equal to the longitude, latitude and mileage of a reference point respectively, and the speed of the GPS device at the current positioning point is set to be equal to the speed of the reference point or is set to be zero.

Description

technical field [0001] The invention relates to the technical fields of sensing technology and the Internet of Things, in particular to a GPS device based on a gravity sensor and a drift processing method thereof. Background technique [0002] The emergence of the Global Positioning System (GPS) allows us to obtain relevant information such as the position and speed of the positioning device at any time with the help of this technology, which has greatly changed our lives. However, due to the drift problem of GPS, it affects the accurate acquisition of information such as the position and speed of the GPS device, and the accurate calculation of related information such as the mileage of the GPS device. [0003] The problem of drift is that when the positioning signal is weak, the position (longitude, latitude), speed and direction information obtained by the GPS device is inaccurate. GPS drift mainly has two appearances, one is static drift, and the other is speed drift. S...
