Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a positioning method according to an embodiment of the present invention. The implementation of the method is described in detail below with reference to this figure.
In this step, the geographic area specifically refers to a geographic area range. Such as a national geographic region or a regional region within a national jurisdiction.
It should be noted that, the target geographical range where the terminal device is currently located is monitored, and it is monitored that the terminal device is currently located at an approximate geographical position, which is not an accurate position.
And 102, if the target geographic range is different from the geographic range where the terminal device is located in the last positioning, determining the weight of each positioning navigation system corresponding to the target geographic range.
Here, the terminal device supports a plurality of different positioning navigation systems. The positioning and navigation performance of different positioning and navigation systems in different countries or regions also differs. For example, the signal quality of the regional navigation system such as QZSS in japan, IRNSS in india, etc. is better than that of GPS in a specific area, and particularly, the QZSS is a satellite-based enhanced version of GPS in the area of japan, and the signal quality is significantly higher than that of GPS, so if the terminal device is in or close to the area of japan (such as the northeast area of china), the navigation positioning of the QZSS is emphasized.
That is, different weights may be set for different positioning and navigation systems according to the geographical range of the terminal device.
And 103, positioning the terminal equipment in the target geographic range based on the weight of each positioning navigation system to obtain the position information of the terminal equipment in the target geographic range.
It should be noted that, because the positioning and navigation performances of the positioning and navigation systems are different in different geographic ranges, the weight of each positioning and navigation system can be determined according to the weight of each positioning and navigation system corresponding to the target geographic range in which the terminal device is currently located, that is, in the target geographic range, according to the quality of the positioning and navigation performances, that is, the weight with good positioning and navigation performances is great, and the weight with poor positioning and navigation performances is small. Therefore, when the terminal equipment is positioned in the step, the positioning processing of the positioning navigation system with large weight can be emphasized in the current geographic range of the terminal equipment, so that the navigation positioning performance of the terminal equipment is further improved, and the terminal equipment is positioned more accurately.
According to the positioning method provided by the embodiment of the invention, the current target geographical range of the terminal equipment is monitored; when the target geographic range is different from the geographic range where the terminal device is located in the last positioning, determining the weight of each positioning navigation system corresponding to the target geographic range; and based on the weight of each positioning navigation system, positioning the terminal equipment in the target geographic range to obtain the position information of the terminal equipment in the target geographic range, so that the navigation positioning performance of the terminal equipment can be improved, and the positioning time and the positioning precision are further improved.
Based on the embodiment shown in fig. 1, as a preferred implementation manner, the determining the weight of each positioning navigation system corresponding to the target geographic area in step 102 may specifically include:
determining target positioning navigation priority of each positioning navigation system corresponding to the target geographic range based on the corresponding relation between the preset geographic range and the positioning navigation priority of each positioning navigation system;
in this step, the positioning performance of the positioning navigation system with high positioning navigation priority is superior to that of the positioning navigation system with low positioning navigation priority. The positioning and navigation priorities of the positioning and navigation systems in different geographic ranges are different.
For example, when the terminal device is in a european region, the positioning and navigation priorities of the positioning and navigation system may be, in order from high to low: GPS, Galileo, GLOONASS; when the terminal equipment is in Japan, the positioning navigation priority of the position navigation system can be as follows from high to low in sequence: QZSS, GPS, GLOONASS; when the terminal equipment is in China, the positioning and navigation priorities of the positioning and navigation system can be as follows from high to low in sequence: beidou Satellite Navigation System (BDS), GPS and GLOONASS.
And determining the weight of each positioning navigation system according to the target positioning navigation priority of each positioning navigation system, wherein the weight corresponding to the positioning navigation system with high positioning navigation priority is greater than the weight corresponding to the positioning navigation system with low priority.
In this step, the terminal can automatically determine the weight of each positioning and navigation system corresponding to the priority of the target positioning and navigation system of each positioning and navigation system by presetting the corresponding relationship between the positioning and navigation priorities of the positioning and navigation systems in different geographic ranges and the weight of the positioning and navigation systems.
Of course, the user can also determine the weight of each positioning and navigation system in real time through the user input for adjusting the weight by combining the target positioning and navigation priority of each positioning and navigation system.
In the implementation manner of determining the weight of each positioning and navigation system, the weight corresponding to the positioning and navigation system with high positioning and navigation priority is greater than the weight corresponding to the positioning and navigation system with low priority, so that the positioning and navigation system with high positioning and navigation priority can be used for positioning and processing the terminal equipment in the geographical range where the terminal equipment is located in the future, the navigation and positioning performance of the terminal equipment is further improved, and the terminal equipment is positioned more accurately.
Based on the embodiment shown in fig. 1, as a preferred implementation manner, step 101 may specifically include:
acquiring geographic identification information of terminal equipment, wherein the geographic identification information comprises: a country code and/or an identifier of a geographical location of a service device, the service device being a device providing network services to the terminal device;
in this step, the geographic identification information of the terminal device is used to indicate the geographic range in which the terminal device is located.
Here, the country code is a set of geographic codes used to represent a country and an overseas territory. The country code is a short string of letters or numbers, which is convenient for data processing and communication. That is, the terminal device can know which country the terminal device is currently located in through the country code.
Specifically, the country code may be acquired through a network that provides a communication service for the terminal device. For example, the country code may be obtained through the terminal device network itself, or may be obtained through a local area network (including but not limited to WIFI/IOT/UWB, etc.), or may be obtained through network roaming, etc.
Also, the identification of the geographic location of the service device includes, but is not limited to: the method comprises the following steps of IP address, terminal equipment peripheral router MAC information (terminal equipment is connected with a wireless local area network, such as WIFI), and terminal equipment peripheral base station information (terminal equipment is connected with a mobile communication network, such as an LTE network).
And determining the current target geographical range of the terminal equipment according to the geographical identification information.
In this step, the geographical identification information is analyzed, so that the target geographical range where the terminal device is currently located can be determined.
Based on the embodiment shown in fig. 1, as an optional implementation manner, step 103 may specifically include:
acquiring navigation data of the satellites searched by each positioning navigation system based on the weight of each positioning navigation system;
the step may further specifically include:
determining hardware characteristic parameters for searching stars in each positioning navigation system based on the weight of each positioning navigation system; and/or respectively endowing the weight of each positioning navigation system to the corresponding star searching algorithm;
it should be noted that, based on the weight of each positioning and navigation system, the configuration of the hardware characteristic parameter for satellite search in the positioning and navigation system with a high weight ratio is higher than the configuration of the hardware characteristic parameter for satellite search in the positioning and navigation system with a low weight ratio, such as strong signal receiving performance, wide bandwidth and the like of the radio frequency point configured by the positioning and navigation system with a high weight ratio, so that the terminal device is more suitable for the hardware characteristic parameter of the positioning and navigation system with a higher weight.
In addition, the weights of the positioning navigation systems are respectively given to the satellite searching algorithms corresponding to the positioning navigation systems, so that the terminal equipment can preferentially search the satellites with higher weights in the galaxy, and the searching time of satellite searching is shortened.
Performing satellite search according to the hardware characteristic parameters; and/or, carrying out satellite search according to the satellite search algorithm;
and receiving navigation data transmitted by the searched satellite.
Respectively endowing the weight of each positioning navigation system to a corresponding positioning navigation algorithm;
the weights of the positioning and navigation systems are respectively given to the corresponding positioning and navigation algorithms, so that the specific position information of the terminal equipment in the target geographic range, which is obtained according to the positioning and navigation algorithm processed in the way, is more dependent on the positioning and navigation system with higher weight in the following steps, thereby improving the navigation and positioning performance of the terminal equipment and achieving the effects of further improving the positioning time and the positioning precision.
And obtaining the position information of the terminal equipment in the target geographic range according to the navigation data and the positioning navigation algorithm.
In order to facilitate the user to view the specific location of the user currently located on the electronic map of the user navigation application of the terminal device in real time, based on the embodiment shown in fig. 1, as a preferred implementation manner, after step 103, the method may further include:
the location information is marked on an electronic map for a navigation application.
In an example, as shown in fig. 2, which is a schematic diagram of a hardware structure of a terminal device applying the positioning method of the present invention, specifically, a country code change monitoring unit inside the terminal device monitors a change of a country code in real time, and if the country code is changed, the country code change monitoring unit refers to a country code corresponding to a situation that positioning performance of each positioning and Navigation System is strong, which is preset in a Global Navigation Satellite System (GNSS) weight management unit, and further assigns weights to each positioning and Navigation System (such as GPS, GLONASS, BDS, QZSS, IRNSS, and Galileo). Here, specifically, the method may include:
and the weight assignment is sent to a hardware star searching unit of the star searching management unit, and the hardware unit can better adapt to the hardware characteristic parameters of the positioning system with higher weight by adjusting the frequency point, the bandwidth and other radio frequency parameters of the hardware star searching unit.
And the weight is given to an algorithm of a software star searching unit of the star searching management unit, so that the algorithm can preferentially search satellites of a star system with higher weight in the sky.
And the weight is given to a positioning navigation algorithm unit, so that the calculated position information is more dependent on a positioning navigation system with higher weight value.
