Embodiment 1

[0020] figure 1 It is an implementation flowchart of the satellite positioning data drift suppression method provided by the embodiment of the present invention, and is described in detail as follows:

[0021] In step S101, the acceleration sensor is used to collect sensor data;

[0022] Acceleration sensors are used to obtain current sensor data in real time.

[0023] In step S102, the collected sensor data is processed to generate a judgment result of whether the satellite positioning data drift should be suppressed;

[0024] Based on the sensor data presented on the acceleration sensor when the object vibrates, the sensor data is statistically analyzed to accurately calculate whether the object is in a moving state or in a static state.

[0025] When the object is in a moving state, a judgment result that does not suppress the drift of the satellite positioning data is generated.

[0026] When the object is in a stationary state, a judgment result for suppressing drift o...

Embodiment 2

[0031] figure 2 It is an implementation flowchart of step S102 of the satellite positioning data drift suppression method provided by the embodiment of the present invention, and is described in detail as follows:

[0032] In step S201, according to the sensor data, the acceleration variance of each axis is generated;

[0033] In step S202, it is judged whether the acceleration variance of each axis is within a preconfigured static range, and the static range includes an upper limit value and a lower limit value of the acceleration variance when in a static state;

[0034] Wherein, the static range can be set by the user, or can be set by the system, which is not limited here.

[0035] In step S203, when the acceleration variance of each axis is within a preconfigured static range, a judgment result is generated that the drift of satellite positioning data needs to be suppressed;

[0036] In step S204, when the acceleration variance of each axis is not within the preconfigu...

Embodiment 3

[0039] image 3 It is the implementation flowchart of step S103 of the satellite positioning data drift suppression method provided by the embodiment of the present invention, and is described in detail as follows:

[0040] In step S301, when the judgment result of suppressing the drift of the satellite positioning data is generated, the speed value in the control satellite positioning data is set to zero, and the latitude and longitude are set to constant values;

[0041] In step S302, when the judgment result of not suppressing the drift of the satellite positioning data is generated, the current satellite positioning data is retained.

[0042] In this embodiment, when the judgment result of suppressing the drift of satellite positioning data is generated, the speed value in the control satellite positioning data is set to zero, and the latitude and longitude are set to constant values, and the satellite positioning data is corrected to facilitate subsequent satellite positi...

Abstract

The invention belongs to the technical field of satellite positioning, and provides a satellite positioning data drifting restraining method and device. The satellite positioning data drifting restraining method includes the steps that an acceleration sensor is used for acquiring sensor data; the acquired sensor data are processed, and a judgment result whether satellite positioning data drifting is restrained or not is generated; according to the judgment result, current satellite positioning data are restrained, or according to the judgment result, the current satellite positioning data are reserved. The satellite positioning data drifting restraining method and device solve the problems that an existing satellite positioning data drifting restraining method needs to detect ACC signals all the time, the effectiveness of the satellite positioning data drifting cannot be accurately judged, and improvement of accuracy of the satellite positioning data drifting is not facilitated. Under the condition that the satellite positioning function is normally used, the ACC signals do not need to be processed, satellite positioning data drifting can be quickly restrained, the restraining accuracy of the satellite positioning data drifting is improved, and the restraining efficiency of the satellite positioning data drifting is improved.

Description

technical field [0001] The invention belongs to the technical field of satellite positioning, in particular to a method and device for suppressing drift of satellite positioning data. Background technique [0002] With the popularity of the positioning function, more and more vehicle monitoring systems are connected to the satellite positioning system to complete the positioning of the vehicle. At the same time, during the transmission process, the signal of the satellite positioning system will attenuate and interfere with the signal after passing through various complex environments such as weather, ground, and buildings, resulting in the deterioration of the accuracy of the satellite positioning information, that is, the occurrence of positioning errors. Accurate question. If the vehicle is in a stationary state, the satellite positioning information should be fixed in theory, but due to the above factors, the satellite positioning information in the vehicle monitoring s...
