Based on the above-mentioned terminal hardware structure and communication network system, various embodiments of the present invention of the composite positioning method of the mobile terminal are proposed.
The invention also provides a screen adjusting method, referring to fig. 3, fig. 3 is a flow chart of a first embodiment of the composite positioning method of the mobile terminal of the invention.
In this embodiment, the composite positioning method of the mobile terminal includes the following steps:
step S10, detecting the relative distance between the mobile terminal and the intelligent bracelet when a positioning command is received;
in the present embodiment, the global positioning system GPS is an aggregate or device (component) configured to determine a spatial position as a target. The ground control part consists of a main control station, a ground antenna, a monitoring station and a communication auxiliary system; the second space part consists of 24 satellites and is distributed on 6 orbit planes; and the user device part consists of a GPS receiver and a satellite antenna. The system can ensure that 4 satellites can be observed at any point on the earth at any moment, so that the satellites can collect the longitude, latitude and altitude of the observation point, and the functions of navigation, positioning, time service and the like can be realized.
It should be noted that the present invention is applied to a mobile terminal supporting a GPS function, and the smart band matched with the mobile terminal also includes a GPS positioning function. The intelligent bracelet is a wearable intelligent device, through the intelligent bracelet, a user can record real-time data such as exercise, sleep, diet and the like in daily life, and synchronize the data with a mobile phone, a tablet and the like, so that the effect of guiding healthy life through the data is achieved.
In the invention, the GPS positioning is preferably performed in a mode of combining the mobile terminal and the intelligent bracelet. Because the mobile terminal and the intelligent bracelet are in data communication through Bluetooth, the mobile terminal cannot communicate beyond the distance range supported by Bluetooth, so that the mobile terminal and the intelligent bracelet are in compound positioning for ensuring, and the relative distance between the mobile terminal and the intelligent bracelet is required to be detected. Specifically, when the mobile terminal receives a positioning command, that is, a target object or a destination needs to be subjected to GPS positioning, the mobile terminal firstly detects the relative distance between the mobile terminal and the intelligent bracelet, and then determines whether the composite positioning can be started or not according to the detection conclusion. Further, when the mobile terminal detects that the relative distance between the mobile terminal and the intelligent bracelet is smaller than or equal to the preset distance, the mobile terminal and the intelligent bracelet can perform data communication through Bluetooth within the preset distance range, which is the premise of composite positioning.
Step S20, when the relative distance is smaller than or equal to a preset distance, acquiring a first coordinate and/or a second coordinate based on the positioning command, wherein the first coordinate is a coordinate acquired from a mobile terminal, and the second coordinate is a coordinate acquired from an intelligent bracelet;
and step S30, generating target coordinates based on the first coordinates and/or the second coordinates.
In this embodiment, when the relative distance between the mobile terminal and the smart band is smaller than or equal to the preset distance, the composite positioning mode is started, and the mobile terminal and the smart band perform GPS positioning respectively, wherein the mobile terminal performs GPS positioning by using one single carrier frequency, the smart band performs GPS positioning by using another single carrier frequency, and GPS positioning data of the mobile terminal is complementary with GPS positioning data of the smart band, so that accuracy of GPS positioning is improved. Specifically, on the mobile terminal side, the mobile terminal starts GPS positioning according to a received positioning command, and acquires a first coordinate after successful positioning, wherein the first coordinate is the coordinate positioned by the GPS of the mobile terminal; on the intelligent bracelet side, the intelligent bracelet starts GPS positioning according to the positioning command, and after successful positioning, second coordinates are obtained, wherein the second coordinates are coordinates to which the intelligent bracelet is positioned by the GPS.
It should be noted that, the GPS positioning of the mobile terminal and the GPS positioning of the smart band have a risk of failure, so that the positioning coordinates can be obtained only when the GPS positioning is successful.
And then, when the intelligent bracelet GPS positioning successfully acquires the second coordinate, the second coordinate is sent to the mobile terminal through Bluetooth, and the mobile terminal couples the first coordinate with the second coordinate to generate a target coordinate.
Further, in an embodiment, step S10 further includes:
and step S60, when the relative distance is larger than the preset distance, starting the mobile terminal to position and acquire the target coordinates.
In this embodiment, when the relative distance between the mobile terminal and the smart band is greater than the preset distance, it is indicated that communication between the mobile terminal and the smart band cannot be performed through bluetooth, that is, the mobile terminal cannot send a positioning command to the smart band, and the smart band cannot start positioning operation, so when the relative distance between the mobile terminal and the smart band is greater than the preset distance, only the GPS positioning response positioning command on the side of the smart terminal is started, and the coordinates to which the GPS of the mobile terminal is positioned are defined as target coordinates.

According to the invention, through the combined positioning of the mobile terminal and the intelligent bracelet, the positioning success rate is improved, and the positioning accuracy is improved, so that stronger practicability and better user experience are brought to users.
Based on the second embodiment, referring to fig. 5, a third embodiment of the composite positioning method of the mobile terminal of the present invention is proposed, in which step S40 includes:
step S41, when first failure information is detected and the first coordinates are acquired, the positioning type is mobile terminal positioning; or alternatively, the first and second heat exchangers may be,

The positioning types include: the method comprises the steps of mobile terminal positioning, bracelet positioning, joint positioning and positioning failure, specifically, when the mobile terminal detects first failure information and acquires a first coordinate, the positioning type is mobile terminal positioning, wherein the first failure information indicates that the intelligent bracelet GPS positioning fails, and the first coordinate is the coordinate acquired by the successful GPS positioning of the mobile terminal; when second failure information is detected and a second coordinate is obtained, the positioning type is bracelet positioning, wherein the second failure information indicates that the GPS positioning of the mobile terminal fails, and the second coordinate is the coordinate obtained by successful GPS positioning of the intelligent bracelet; similarly, when the first coordinate and the second coordinate are acquired simultaneously, the positioning type is joint positioning; and when the first failure information and the second failure information are detected at the same time, the positioning type is positioning failure.
Further, in an embodiment, step S44 further includes:
step S45, when the positioning type is positioning failure, outputting prompt information of positioning failure.

in this embodiment, when the mobile terminal outputs the prompt information of the positioning failure, the mobile terminal determines the type of the detected operation instruction, and executes different operation flows according to the specific type of the operation instruction. If the mobile terminal is a touch screen, the operation instruction may be triggered by clicking a menu key, or may be triggered by a physical key of the mobile terminal, and the specific triggering manner of the operation instruction is not limited in this embodiment.
Specifically, the determination command indicates that the mobile terminal performs GPS positioning again, so that when the operation command is the determination command, the mobile terminal stops outputting the prompt information, and the GPS positioning is retried, that is, the step of detecting the relative distance between the mobile terminal and the bracelet is continued to be performed.
And S48, stopping outputting the prompt information and exiting the positioning command when the operation command is a non-determination command.

Specifically, when the positioning type is mobile terminal positioning, the mobile terminal side GPS positioning is successfully indicated and the first coordinate is returned, meanwhile, the intelligent bracelet GPS positioning failure is indicated, and the first coordinate is taken as the target coordinate.
It should be noted that, the data stored in the preset storage area must include a positioning type, but whether the first coordinate and the second coordinate can be successfully acquired needs to be judged according to the positioning type and then acquired, so that it is recommended to acquire the positioning type first and then acquire the first coordinate and the second coordinate according to the positioning type.
Step S33, when the positioning type is bracelet positioning, the target coordinates are the second coordinates;
in this embodiment, the saved first coordinate and/or second coordinate and the positioning type are obtained from the preset storage area, when the positioning type is the positioning of the bracelet, it is indicated that the positioning of the intelligent bracelet is successful and the second coordinate is returned, and meanwhile, it is indicated that the positioning of the mobile terminal is failed, and the second coordinate is taken as the target coordinate.
And step S34, when the positioning type is joint positioning, the target coordinates are summed with third coordinates and fourth coordinates, wherein the third coordinates are obtained by multiplying a first weight coefficient by the first coordinates, and the fourth coordinates are obtained by multiplying a second weight coefficient by the second coordinates.
