Please refer to FIG. 1 , the present invention proposes a method for filtering mobile hopping data, comprising the following steps:

S7. Acquire travel information of the device terminal according to the acquired GPS data packet information of the device terminal.

The present invention is used for data collection of mobile equipment terminals, and specifically realizes filtering and eliminating mobile jump data, so as to realize the problems of inaccurate positioning information and unclear traveling direction caused by the drift of position information of equipment terminals when moving.

In this embodiment, since the GPS information at each moment is different for a mobile device, in order to filter out correct information, it is necessary to obtain specific data of the longitude, latitude, altitude and speed of the device terminal. The device obtains the GPS data packet information, among which the GPS data information includes a variety of information factors, specifically longitude, latitude, altitude, and speed. Time period, in each time period, the GPS data packet information received by GPS satellites is different. In order to ensure that the GPS data packet information received in each time period is correct, it is necessary to compare the GPS data packet information with the benchmark. The data packet information is compared and filtered, so it is necessary to determine the accuracy of the reference data packet first. When receiving a GPS data packet information, each factor and the device terminal can not change the physical quantity such as acceleration. Factor data and GPS data obtained after calculation The factors of the packet information are compared. If the comparison result does not exceed the preset range, the GPS data packet information can be determined as the reference data packet information. At this time, a GPS data packet information can be obtained after a certain interval and the The factors of the GPS data packet information are compared with the factors of the reference data packet information to determine whether it exceeds the value range that each factor should reach in this time. If the information drifts, the GPS data packet information of this period of time will be eliminated. If it does not exceed the proper value range, it means that the GPS data packet information of this period of time has not drifted. At this time, the GPS data packet information of this period of time can be The data packet information is compared with the GPS data packet information of the next time period as the reference data packet information. After multiple filtering, the traveling direction of the equipment terminal can be obtained according to the GPS data packet information of each time without drift.

In one embodiment, the step of judging whether the GPS data packet information is the data packet information preset by the device terminal includes:

Acquire the variation of the speed in the moving state of the device terminal within the first preset time;

According to the first preset time, the variation of each factor is calculated and compared with the actual variation of the equipment terminal to determine whether it exceeds the first preset value, wherein the actual variation is the data configured by the equipment terminal;

If the actual change exceeds the first preset value, the GPS data packet information is eliminated and the GPS data packet information is re-acquired immediately.

In this embodiment, for the device terminal, no matter how the reported factor changes, it will not deviate from the physical properties of the device terminal itself, such as acceleration. No matter how long the movement is, the acceleration will not exceed the established upper limit, so When establishing the reference data packet information, you can obtain the second piece of GPS data packet information at a certain time interval after the first acquisition of the GPS data packet information, and then calculate the two pieces of GPS data packet information to obtain the acceleration and other physical quantities in this time period , and compare the two accelerations to determine whether they can be used as the reference data packet information, and a second satellite positioning device is also provided on the equipment terminal to directly obtain the GPS data packet of the current position in the equipment terminal.

In one embodiment, if each factor of the next GPS data packet information does not exceed the corresponding preset threshold, the next GPS data packet information is determined to be the reference data packet information, and replaces the previous reference data packet information. steps, including:

If it is determined that each factor of the next GPS data packet information does not exceed the corresponding preset threshold, obtain the travel direction angle of the device terminal, and determine whether the travel direction angle exceeds the second preset value;

If the travel direction angle is less than or equal to the second preset value, the next GPS data packet information is determined as the reference data packet information, and the previous reference data information is replaced.

In this embodiment, when the equipment terminal is moving, although the factors of the GPS data packet information do not exceed the preset threshold, if the moving direction of the equipment terminal changes suddenly, the navigation device, etc. The device terminal is judged to be turning and other situations, so it is necessary to clear the data packets in which this situation occurs, and the range of the second preset value for the direction of travel is set to 5°. When the value is set, the packet data can be judged as the data without drift and replaced with the previous reference data packet information.

In another embodiment, when the travel direction angle is greater than the range of the second preset value, it means that the packet data has drifted. At this time, the packet data is filtered, and the above-mentioned reference data packet information is used as the reference to continue the process. Compared.

In one embodiment, the step of determining that the GPS data packet information is the reference data packet information further includes:

Obtain the road map and terrain data of the current location of the device terminal with the reference data packet information;

within the second preset time, obtain the pre-positioning data calculated by the device terminal in combination with the road map and the terrain data;

Compare the pre-positioning data with the factors of the next GPS data packet information one by one;

It is judged whether each factor in the information of the next GPS data packet is within the range of a predetermined number of digits.

In this embodiment, after the reference data packet information is determined, the road map and terrain data of the current location of the equipment terminal can be obtained to obtain the road information and terrain information of the current location. Calculate the position range that the device terminal should reach in the interval time. When the next GPS data packet information is obtained, each factor can be compared with the calculated position range to determine whether the acquired GPS data packet information is not. Drift occurs, and the factors that may exceed the threshold within the preset range are retained in combination with road information and terrain data. For example, when the device terminal is in a mountainous area, since the slope of the general mountain road needs to be considered in the design, most mountain roads are They are all curved, and the travel direction angle will change greatly when driving so that it exceeds the second preset value. At this time, after comparing the road information, the behavior that exceeds the second preset value can be identified. In order to prevent data drift, for example, when the device terminal is climbing a mountain, the altitude will exceed the preset threshold. After comparing the road information and terrain information, the behavior exceeding the preset threshold can be considered as no data drift.

In one embodiment, if any factor exceeds the corresponding preset threshold, it is determined that the next GPS data packet information is information data that has drifted, and the step of eliminating the next GPS data packet information also includes:

Calculate each factor of the next GPS data packet information at the third preset time under different travel direction angles and compare it with the factor of the reference data packet information to determine whether it exceeds the preset threshold of the factor of the reference data packet information;

If not, remove the GPS data packet information.

In this embodiment, if the reference data packet information is incorrect, then the GPS data packet information received next will be judged to be incorrect data. At this time, it is necessary to check whether the reference data packet information is correct or not. Make a judgment. At this time, you can use the same speed, road and other factors, and then perform simulation calculations in different directions. If the result of the simulation calculation is the same as the factor value of the GPS data packet information, it means that the reference data packet information cannot be used. Benchmark, it is necessary to re-determine the reference data packet information. If the result obtained by the simulation calculation is not the same as the factor value of the GPS data packet information, it means that the GPS data packet information has drifted and filtered.

In one embodiment, if any factor exceeds the corresponding preset threshold, it is determined that the next GPS data packet information is information data that has drifted, and after the step of eliminating the next GPS data packet information, the step further includes:

If hopping data is received in the next GPS data packet information, the first control instruction is executed: the control device terminal sends the GPS data packet information to other satellites.

In this embodiment, because the equipment terminal generally only occasionally occurs data hopping, when the satellite receives the hopping data multiple times in a row, the first control instruction changes the receiving object of the equipment terminal data from a single satellite. Replaced with multiple different satellites.

In one embodiment, after the step of controlling the device terminal to send the GPS data packet information to other satellites, the step further includes:

If the location information data packets transmitted by the equipment terminal continue to appear hopping data after the first control instruction is executed for many times, the second control instruction is executed to control the equipment terminal to restart.

In this embodiment, when continuous jumping data still occurs after the first control instruction is repeatedly executed to replace the data upload object, it means that there is no problem with the receiving terminal, and the equipment terminal needs to be detected at this time, so The second control instruction restarts the module used by the device terminal for positioning.
