First embodiment
Fig. 2 shows a flowchart of a motion trajectory query method according to a first embodiment of the present invention, please refer to fig. 2, which describes a processing flow of a beidou satellite, and the method includes:
step S110, a query request is obtained.
The Beidou satellite can specifically acquire the query request from the user terminal, in this embodiment, the user terminal can specifically be a Beidou mobile phone, a Beidou automobile and the like, and when the user terminal needs to query the motion track of the user terminal, the query request is sent to the Beidou satellite.
Step S120, according to the time period to be queried in the query request, obtaining a plurality of time point information in the time period to be queried.
The query request specifically comprises a time period to be queried, and the Beidou satellite can acquire the time period to be queried in the query request and then acquire a plurality of time points in the time period to be queried.
Specifically, when a user needs to query the motion trajectory of the user terminal between 9 am and 11 am, a corresponding query request is sent to the Beidou satellite through the user terminal, and after the Beidou satellite receives the query request, the time period to be queried obtained from the Beidou satellite is 9 am to 11 am. Therefore, the Beidou satellite can inquire a plurality of time point information between 9 am and 11 am.
The plurality of time point information can be accurate to seconds, namely, each second generates one time point information and also has position information corresponding to the time point information.
Step S130, obtaining location information corresponding to each of the plurality of time point information according to the plurality of time point information.
Because each time point information is corresponding position information, the Beidou satellite acquires the position information corresponding to the time point information.
Step S140, transmitting the location information.
The Beidou satellite can send the acquired position information corresponding to the time point information to the user terminal, and the user terminal can display the motion trail formed by the position information. Specifically, the location information may be latitude and longitude information.
Fig. 3 shows the processing steps of the beidou satellite before step S110 shown in fig. 2, specifically including:
step S101, a plurality of pieces of location information and time point information corresponding to each of the plurality of pieces of location information are obtained from a terminal.
The Beidou satellite can specifically obtain a plurality of pieces of position information of the user terminal and time point information corresponding to each piece of position information from the user terminal, and stores the position information and the time point information.
Step S102, storing the plurality of location information in a first storage area.
The Beidou satellite can store the position information and the time point information separately, so that the data are not influenced by the searching speed due to the overlarge quantity during searching.
Specifically, the Beidou satellite can store an integer part of the longitude information in a first sub-area of the first storage area; storing a fractional portion of the longitude information in a second sub-region of the first memory region. Storing an integer portion of the latitude information in a third sub-region of the first memory region; storing a fractional portion of the latitude information in a fourth sub-region of the first memory region. The position information is stored according to the division of longitude information and latitude information, and then the longitude information and the latitude information are respectively stored according to an integer part and a decimal part.
When reading data, the Beidou satellite can read the integral part of longitude information and latitude information firstly so as to determine an area azimuth in a larger range at the user terminal, and then read the decimal part of the longitude information and the latitude information so as to read the more accurate position of the user terminal.
Step S103, storing the time point information in a second storage area.
The Beidou satellite can store the time point information and the position information separately.
Step S104, establishing a mapping relation between the position information and the time point information corresponding to the position information.
The Beidou satellite establishes a mapping relation between the position information and the corresponding time point information, and when the time point information is found, the position information corresponding to the time point information can be found according to the mapping relation.
Fig. 4 shows a specific implementation manner of the motion trail query method provided in the first embodiment of the present application, which specifically includes the following steps:
step S110, a query request is obtained.
Similar to step S110 in fig. 2, further description is omitted here.
Step S210, in the time period to be queried, obtaining a plurality of first time point information according to a predetermined time interval.
Specifically, the time period to be queried is 9 am to 11 am as an example. The predetermined time interval is half an hour as an example, the beidou satellite may obtain five pieces of first time point information of 9 am, 9 am 30 min, 10 am 30 min and 11 am in the time period to be queried, which is 9 am to 11 am. Of course, the predetermined time interval may be other values, and the specific values should not be construed as limiting the application.
Step S220, obtaining first position information corresponding to each first time point information in the plurality of first time point information.
Then, first position information corresponding to five pieces of first time point information, namely, 9 points, 30 minutes, 10 points, 30 minutes and 11 points, is obtained.
Step S230, sending the first location information.
And sending the obtained first position information to the user terminal so that the user terminal can firstly display the approximate motion track of the user terminal passing through in the time point to be inquired according to the first position information.
Step S240, in the time period to be queried, obtaining a plurality of second time point information.
Specifically, the second time point information may be time point information other than the first time point information in the time period to be queried. And after the Beidou satellite sends the first position information to the user terminal, a plurality of second time point information are obtained. The second time point information may be acquired in units of seconds.
Step S250, obtaining second position information corresponding to each of the plurality of second time point information.
Since the time point information and the position information are mapped, the second position information respectively corresponding to the second time point information can be obtained according to the mapping.
Step S260, sending the second location information.
And sending the second position information to the user terminal so that the user terminal displays the motion trail of the user terminal in detail according to the second position information.
The method for querying the motion trail provided by the first embodiment of the application can store the position information and the time point information in different storage areas, and establish a mapping relation between the two storage areas, so that when a user terminal needs to query the motion trail, the Beidou satellite firstly acquires the time point information, and then acquires the position information according to the mapping relation between the time point information and the position information.
