Description

Method and terminal for adjusting positioning method

The present application claims the priority of the Chinese Patent Application, filed on March 30, 2017, which is hereby incorporated by reference.

Technical field

The present application relates to the field of satellite positioning technologies, and in particular, to a method and a terminal for adjusting a positioning method.

Background technique

With the development of satellite positioning and navigation systems, the Global Positioning System (GPS) including the United States, the Global Navigation Satellite System (GLONASS) in Russia, and the Beidou satellite navigation in China have been formed. Global Navigation Satellite System (GNSS) for systems such as positioning systems. Due to the limited coverage of satellite signals in each navigation and positioning system, for single-mode satellite navigation schemes, in the case of poor satellite signals, problems such as poor positioning accuracy and slow positioning may occur. In order to solve these problems, GNSS support has emerged. Multimode satellite navigation equipment.

Currently, devices that support multi-mode satellite navigation generally use dual-mode positioning. For example, GPS and GLONASS can be used for positioning at the same time, or GPS and Beidou satellite navigation and positioning system can be used for positioning at the same time. When dual-mode positioning is used, the positioning chip receives positioning signals of two satellites. For example, when using GPS and GLONASS positioning, the positioning chip receives the positioning signal of the GPS satellite and the positioning signal of the satellite of GLONASS, if in some positions, If the positioning signal of one of the satellites is poor, or the positioning signal of one of the satellites is not received, the phenomenon that the positioning signal for positioning is missing may result in low positioning accuracy.

Summary of the invention

The embodiment of the present invention provides a method and a terminal for adjusting a positioning mode, which can solve the problem that the positioning accuracy is low when a positioning signal is poor or a signal is missing when the positioning signal is poor or the signal is missing.

To achieve the above objectives, the present application adopts the following technical solutions:

In a first aspect, an embodiment of the present application provides a method for adjusting a positioning manner, where the method includes: receiving, by a terminal, a positioning request, and then performing positioning by using a common positioning mode of the primary positioning system and the first auxiliary positioning system, and then periodically detecting the terminal. First positioning data, the first positioning data includes a signal quality parameter and a positioning error parameter of the satellite in the first auxiliary positioning system, and the terminal uses the primary positioning system and the second in response to the first positioning data not satisfying the predetermined condition The common positioning mode of the auxiliary positioning system performs positioning, wherein the first auxiliary positioning system and the second auxiliary positioning system are two different positioning systems supported by the terminal other than the primary positioning system. In this way, when positioning is performed by using two positioning systems, if the signal quality and the positioning accuracy of the plurality of satellites in the first auxiliary positioning system do not satisfy the predetermined condition, the first auxiliary positioning system can be replaced with the second auxiliary positioning system, such that This avoids the problem of low positioning accuracy that can occur with the continued use of the first auxiliary positioning system.

In a possible design, when the signal quality parameter of the preset number of satellites in the first auxiliary positioning system is less than the first threshold, or the positioning error parameter of the preset number of satellites is greater than the second threshold, the terminal uses the main The positioning mode of the positioning system and the second auxiliary positioning system are positioned. Visible, due to the preset number The signal quality parameters of the satellites are all smaller than the first threshold, or the positioning error parameters of the preset number of satellites are greater than the first threshold. If the positioning is continued using the first auxiliary positioning system, the positioning accuracy is poor, and the application is timely The replacement of the auxiliary positioning system into the second auxiliary positioning system avoids the problem of poor positioning accuracy caused by continuing to use the first auxiliary positioning system.

In a possible design, after the terminal uses the co-localization mode of the primary positioning system and the second auxiliary positioning system for positioning, the terminal periodically detects the second positioning data, and the second positioning data includes the satellite in the second auxiliary positioning system. a signal quality parameter and a positioning error parameter, wherein when the signal quality parameter of the preset number of satellites in the second auxiliary positioning system is less than the first threshold, or the positioning error parameter of the preset number of satellites is greater than the second threshold, the terminal uses the primary positioning The system is positioned separately. It can be seen that if the accuracy of positioning using the first auxiliary positioning system and the second auxiliary positioning system is relatively low, the terminal only uses the primary positioning system for positioning, and can avoid positioning caused by inaccurate positioning data to determine position information. The problem of low precision, and when the signal quality of the preset number of satellites is poor in both the first auxiliary positioning system and the second auxiliary positioning system, continuing to use the first auxiliary positioning system or the second auxiliary positioning system may generate unnecessary The power consumption, adjusting the positioning mode to the positioning of the main positioning system alone can reduce unnecessary power consumption.

In one possible design, after the terminal is individually positioned using the primary positioning system, the following steps are also required:

S1. When a monitoring period is reached, the terminal uses the common positioning mode of the primary positioning system and the first auxiliary positioning system for positioning;

S2. The terminal detects the first positioning data.

S3. If the signal quality parameter of the preset number of satellites in the first auxiliary positioning system is less than the first threshold and the positioning error parameter is greater than the second threshold, the terminal uses the primary positioning system to separately locate.

The terminal ring performs the above steps S1 to S3 until the signal quality parameter of the preset number of satellites in the first auxiliary positioning system is greater than the first threshold, and the positioning error parameter of the preset number of satellites is smaller than the second threshold. It can be seen that, in the case of good satellite signal quality, the positioning accuracy of multi-mode positioning is higher than that of single-mode positioning. After the positioning mode is adjusted to be separately positioned by the main positioning system, the terminal will try to adjust the positioning mode to multi-mode. Positioning, which helps to improve positioning accuracy.

In a possible design, the primary positioning system is GPS, the first auxiliary positioning system is GLONASS, and the second auxiliary positioning system is Beidou satellite positioning system; or the first auxiliary positioning system is Beidou satellite positioning system, and the second auxiliary positioning is The system is GLONASS.

In one possible design, the signal quality parameter is the carrier power and noise power ratio, and the positioning error parameter is the horizontal accuracy factor.

In a second aspect, the present application provides an apparatus for adjusting a positioning manner, and the apparatus may implement the functions performed by the terminal in the foregoing first aspect, and the functions may be implemented by using hardware or by executing corresponding software by hardware. The hardware or software includes one or more modules corresponding to the above functions.

In one possible design, the apparatus includes a processor, a communication interface, and a positioning chip configured to support the apparatus to perform the corresponding functions of the above methods. The communication interface is used to support communication between the device and other network elements. The positioning chip is configured to be positioned according to a positioning mode determined by the processor, and the apparatus may further include a memory for coupling with the processor, which stores program instructions and data necessary for the device.

detailed description

The system architecture and the service scenario described in this application are for the purpose of more clearly explaining the technical solutions of the present application, and do not constitute a limitation on the technical solutions provided by the present application. Those skilled in the art may know that with the evolution of the system architecture and new services. The appearance of the scenario, the technical solution provided by the present application is equally applicable to similar technical problems.

It should be noted that, in the present application, the words "exemplary" or "such as" are used to mean an example, illustration, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of the words "exemplary" or "such as" is intended to present the concepts in a particular manner.

It should be noted that in the present application, "(English: of)", the corresponding "(corresponding, relevant)" and "corresponding" may sometimes be mixed. It should be noted that When the difference is made, the meaning to be expressed is the same.

Before describing the technical solutions of the present application in detail, for the sake of easy understanding, the scenarios applied by the embodiments of the present application are first introduced.

Embodiments of the present application are applied to a navigation system as shown in FIG. 1, which includes a terminal and a satellite for achieving positioning.

The terminal includes a positioning application, a positioning management module, and a positioning chip. The positioning chip can be a GNSS chip, and the positioning management module is a logical adaptation layer between the positioning application and the positioning chip, and is used to process the positioning of the user received by the positioning application. The request is further configured to configure an initialization parameter of the positioning chip, determine position information according to the positioning data provided by the positioning chip, and adjust a positioning mode of the positioning chip.

The satellites used to achieve positioning may include GPS satellites in GPS, GLONASS satellites in GLONASS, and Beidou satellites in the Beidou satellite navigation and positioning system.

The terminal may include various handheld devices having wireless communication functions, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to the wireless modem, and various forms of terminals, mobile stations (MSs), User equipment (UE), terminal equipment (Terminal Equipment), soft terminal, and so on. Common terminals include, for example, mobile phones, tablets, notebook computers, PDAs, mobile internet devices (MIDs), wearable devices such as smart watches, smart bracelets, pedometers, and the like. For convenience of description, in the present application, the above mentioned devices are collectively referred to as terminals.

It should be noted that in the prior art, when dual mode positioning is used, the two systems used by the positioning chip are fixed. For example, if the positioning chip uses GPS and GLONASS positioning, the positioning chip can only receive GPS satellites and GLONASS. The satellite signal cannot receive signals from other satellites (such as the Beidou satellite). If the signal of the GLONASS satellite at the user's current location is weak, it is likely that the positioning information returned by the GLONASS satellite to the positioning signal is inaccurate, resulting in low positioning accuracy. Or, if the current location of the user is not within the coverage of the GLONASS satellite, the positioning chip cannot receive the signal of the GLONASS satellite, but the positioning chip will continue to recognize the signal of the GLONASS satellite, which will generate unnecessary work. Consumption.

In order to solve the above problem, the positioning management module is added to the terminal of the application, and the user can send a positioning request to the positioning management module through the positioning application in the terminal, and then the positioning management module can configure the initial positioning mode of the positioning chip, for example, the initial positioning mode can be Positioning the GPS and the GLONASS together, and then in the subsequent positioning process, the positioning chip periodically sends the positioning data to the positioning management module, so that the positioning management module feeds back the position information to the positioning application, and after the positioning management module receives the positioning data, The positioning accuracy and the signal strength of each satellite carried in the positioning data are detected. When it is determined that the positioning accuracy and signal strength of a certain positioning satellite are both poor, the positioning mode can be adjusted. For example, if the positioning accuracy and signal strength of multiple GLONASS satellites are poor, then GLONASS can be turned off, the Beidou satellite navigation and positioning system can be turned on, and the positioning mode can be adjusted to be co-located by GPS and Beidou satellite navigation and positioning system, thus avoiding GLONASS. When the positioning accuracy and signal strength of the satellite are both poor, the problem of low positioning accuracy caused by GLONASS positioning continues to be used.

The method for adjusting the positioning mode provided by the present application will be specifically described below in conjunction with the navigation system shown in FIG. 1 and the terminal shown in FIG. 2 .

For ease of understanding, the parameters involved in the embodiments of the present application are first described.

1), the main positioning system

In the case of dual-mode positioning, GPS is generally used, and positioning systems other than GPS, such as GLONASS or Beidou satellite positioning system, are used as positioning. In the present application, the main positioning system is described by taking GPS as an example, and the satellite in the GPS is called a GPS satellite.

2) First auxiliary positioning system

The first auxiliary positioning system may be a positioning system other than the main positioning system, for example, may be a GLONASS or a Beidou satellite navigation and positioning system. In the present application, the first auxiliary positioning system is GLONASS, and the satellite in the first auxiliary positioning system. Known as the GLONASS satellite.

3), second auxiliary positioning system

The second auxiliary positioning system may be a positioning system other than the primary positioning system and the first auxiliary positioning system, for example, may be a GLONASS or a Beidou satellite navigation and positioning system. In the present application, the second auxiliary positioning system is a Beidou satellite navigation and positioning system. For example, the satellite in the second auxiliary positioning system is called the Beidou satellite.

As shown in FIG. 3, in order to avoid the problem of low positioning accuracy, the embodiment of the present application provides an adjustment setting. The method of the bit mode, FIG. 3 is described by the positioning application inside the terminal, the positioning management module, and the interaction process of the positioning chip, and the method includes:

301. The positioning application sends a positioning request to the positioning management module, and the positioning management module receives the positioning request.

Wherein, when the user needs to use the map navigation, or needs to determine the current location of the user, the positioning application in the terminal can be used for positioning or navigation. After the positioning application receives the positioning or navigation operation input by the user, the positioning application can be The location management module sends a location request.

302. The positioning management module sends an initial configuration parameter to the positioning chip, and the positioning chip receives the initial configuration parameter.

The initial configuration parameter includes a positioning mode and a positioning data type, and the positioning data type includes: a latitude and longitude and a signal quality parameter and a positioning error parameter of the satellite in the positioning system corresponding to the positioning mode.

In a possible implementation manner, the signal quality parameter is a carrier-to-noise-density ratio (C/N ₀ ), and the positioning error parameter is a horizontal dilution of precision (HDOP). .

The positioning data type is the type of positioning data that the bit chip needs to feed back to the positioning management module, that is, the positioning chip needs to feed back the positioning latitude and longitude to the positioning device, the detected GPS satellite C/N ₀ and HDOP, and the detected C/N ₀ and HDOP of the GLONASS satellite.

Among them, C/N _{0 is} used to indicate the signal quality of the satellite, and the larger the C/N ₀ is, the better the signal quality is. HDOP is used to indicate the positioning accuracy of the satellite. The smaller the C/N _{0 is, the} smaller the positioning error is, and the better the positioning accuracy is.

303. The positioning chip configures the positioning mode as a common positioning mode of GPS and GLONASS according to initial configuration parameters.

The method for co-locating GPS and GLONASS is the same as the dual-mode positioning method in the prior art, and details are not described herein again.

It can be understood that after the positioning chip configures the positioning mode as the common positioning mode of GPS and GLONASS, the positioning signal can be detected by GPS and GLONASS, the positioning signals of the GPS satellite and the GLONASS satellite are detected, and the first positioning data is determined according to the positioning signal.

304. The positioning chip periodically sends the first positioning data to the positioning management module, and the positioning management module periodically receives the first positioning data, where the first positioning data includes the C/N ₀ and the HDOP of the GLONASS satellite detected by the positioning chip.

The first positioning data further includes the latitude and longitude of the target position collected by the GPS satellite, and the latitude and longitude of the target position collected by the GLONASS satellite. After receiving the latitude and longitude information, the positioning management module can use the latitude and longitude information as the terminal. The targeting app provides location services.

305. When the C/N ₀ of the preset number of satellites in the GLONASS is less than the first threshold or the HDOP is greater than the second threshold, the positioning management module adjusts the positioning mode of the positioning chip to a common positioning mode of the GPS and the Beidou satellite navigation and positioning system.

Wherein, if the first auxiliary positioning system is GLONASS, the second auxiliary positioning system may be a positioning system other than GPS and GLONASS supported by the positioning chip, for example, if the positioning chip further supports the Beidou satellite navigation and positioning system, the second auxiliary The positioning system can be a Beidou satellite navigation positioning system, and if the positioning chip further supports multiple positioning systems, the positioning management module can select a positioning system with the best quality of service as the second auxiliary positioning system. In the following, the second auxiliary positioning system is taken as an example of the Beidou satellite navigation and positioning system.

It can be understood that if the C/N _{0 of} a preset number of GLONASS satellites (for example, four GLONASS satellites) is smaller than the first threshold, or the HDOP of the four satellites is greater than the second threshold, the signal of the GLONASS satellite is poor. Or, the positioning accuracy is low. If the GLONASS satellite positioning is used continuously, the problem of inaccurate positioning of the waves is easy to occur, so other positioning systems can be selected to continue positioning.

The first threshold may be 20 db and the second threshold may be 1.5.

306. The positioning chip periodically sends second positioning data to the positioning management module, where the second positioning data includes C/N ₀ and HDOP of the satellite in the second auxiliary positioning system detected by the positioning chip.

307. When the C/N ₀ of the preset number of Beidou satellites in the Beidou satellite positioning navigation system is less than the first threshold, or the HDOP of the preset number of Beidou satellites is greater than the first threshold, the positioning management module adjusts the positioning mode to GPS alone. Positioning.

Wherein, if the C/N _{0 of the} preset number of Beidou satellites in the Beidou satellite positioning navigation system is less than the first threshold, or the HDOP of the preset number of Beidou satellites is greater than the second threshold, the Beidou in the Beidou satellite positioning navigation system Satellites currently have problems of poor signal quality or low positioning accuracy. In order to avoid the use of inaccurate positioning data for positioning and affecting positioning accuracy, the positioning management module can adjust the positioning mode to GPS positioning alone, which can also reduce the positioning. Power consumption.

At the same time, since the location that needs to be located during the navigation process is also changing, the location that needs to be located may be in the area where the GLONASS signal quality coverage is good, so the positioning system will try to re-enable GLONASS to improve the positioning accuracy.

It can be understood that if the C/N _{0 of the} preset number of satellites in the Beidou satellite positioning navigation system is greater than the first threshold and the HDOP is less than the second threshold, the positioning chip will continue to use the GPS and the Beidou satellite positioning navigation system to co-locate.

308. When a monitoring period is reached, the positioning management module adjusts the positioning mode to a common positioning mode of GPS and GLONASS.

The monitoring period is a preset length of time. When the positioning chip uses the positioning mode of the GPS separately positioned to reach the length of time, the positioning management module can try to restart the GLONASS.

309. The positioning chip sends the first positioning data to the positioning management module.

The first positioning data includes C/N ₀ and HDOP of the GLONASS satellite detected by the positioning chip.

310. Determine whether the C/N _{0 of the} preset number of GLONASS satellites in the GLONASS is less than the first threshold and the HDOP is greater than the second threshold. If yes, execute step 311. If no, return to step 304 above.

311. The positioning management module adjusts the positioning mode to be separately positioned by the main positioning system. Then return to step 308.

It should be noted that if there is a preset number of satellites in the GLONASS, the C/N _{0 is} smaller than the first threshold and the HDOP is greater than the second threshold, indicating that the signal quality of the GLONASS satellite is still poor and the positioning accuracy is low, so Re-adjust the positioning mode that is separately positioned by GPS. When the next monitoring period is reached, try to enable GLONASS again. It is determined that the preset number of satellites in GLONASS has a C/N ₀ greater than the first threshold, or a preset number. When the HDOP of the satellite is less than the second threshold, the positioning mode in which the GPS and the GLONASS are co-located is determined, and the process returns to the above step 304, and the positioning mode is adjusted in real time by the positioning data periodically reported by the positioning chip.

The method for adjusting the positioning mode provided by the embodiment of the present application is compared with the prior art, when the satellite signal is poor, the positioning accuracy is low. In the embodiment of the present application, the positioning of the positioning chip is determined. After the mode, the positioning chip periodically reports the positioning data to the positioning management module, and the positioning data includes The signal quality parameter and the positioning error parameter of the satellite in the first auxiliary positioning system detected by the chip, and the positioning management module can adjust the positioning mode according to the signal quality parameter and the positioning error parameter of the satellite, if the first auxiliary positioning system is determined If the signal quality parameters of the plurality of satellites are all smaller than the first threshold, or the positioning error parameters of the plurality of satellites are greater than the second threshold, the positioning of the first auxiliary positioning system is continued, and the positioning accuracy may be low. The positioning management module replaces the first auxiliary positioning system with the second auxiliary positioning system for positioning, so as to avoid the problem that the positioning accuracy of positioning using the first auxiliary positioning system is low.

In addition, when the signal quality parameters of the plurality of satellites in the first auxiliary positioning system are all smaller than the first threshold, continuing to use the first auxiliary positioning system for positioning may generate a large amount of unnecessary power consumption, and stop using the first auxiliary positioning system in time. Positioning can reduce unnecessary power consumption.
