Description

Technical Field

[0001] The present invention relates to the field of automatic control technology, and in particular to a positioning system switching method, device, equipment and medium. Background Art

[0002] With the rapid development of mobile communication technology, the Global Positioning System (GPS) has become an indispensable function in devices such as smartphones and car navigation. However, as users' requirements for positioning accuracy, reliability and coverage increase, a single GPS system can no longer meet the needs of all scenarios. Especially in some special environments or emergency situations, such as urban canyons, indoors, mountainous areas where GPS signals are weak, or in areas such as agriculture and surveying and mapping that require higher positioning accuracy, a single GPS system is difficult to provide stable and reliable services. In addition, with the gradual improvement of China's independently developed Beidou Satellite Navigation System (BDS), the high-precision positioning services it provides worldwide provide new options for the diversification and backup of the Global Navigation Satellite System (GNSS).

[0003] Currently, most smartphones and navigation devices are pre-installed with GPS as the main positioning system. Some high-end devices may support multiple global navigation satellite systems, such as GPS, GLONASS, Galileo, etc., to improve the accuracy and reliability of positioning. However, these devices usually adopt a manual switching method, and users need to manually select which navigation system to use according to the current environment and needs. In addition, some devices may support automatic switching functions, but this switching is usually based on a simple judgment of signal strength and lacks intelligent recognition of users' specific needs and scenarios.

[0004] Although existing technologies have made some progress, they still have obvious shortcomings. Most devices rely on a single GPS system and cannot provide a backup solution when the GPS signal is weak or unavailable. In some special environments or emergency situations, a single GPS system is difficult to provide sufficient positioning accuracy and reliability. Therefore, there is an urgent need for a method to automatically switch navigation systems according to user needs and environmental changes. Summary of the invention

[0040] The purpose, features and advantages of this application will be further described in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0041] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0042] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The main solution of the embodiment of the present application is: by obtaining the first navigation information, when the first navigation information does not meet the preset positioning requirements, obtaining the second positioning system attributes and the second positioning system configuration, when the second positioning system attributes and the second positioning system configuration both meet the preset power-on requirements, sending a control instruction, turning on the second positioning system, switching the navigation mode to the second navigation mode, and obtaining the second navigation information.

[0044] The navigation system mainly includes a global satellite navigation system and a regional navigation system, such as a global positioning system (GPS), GLONASS, Galileo, Beidou positioning system, etc. In the embodiment of the present application, the first navigation system refers to a traditional GPS positioning system, and the second navigation system refers to a Beidou positioning system. Specifically, the mobile phone uses GPS for positioning by default under normal circumstances. The GPS system can provide relatively accurate location information, but in certain specific environments (such as urban canyons with tall buildings, densely forested areas, etc.), there may be weak signals or inaccurate positioning, and the Beidou positioning system needs to be started at this time.

[0045] Based on this, the embodiment of the present application provides a positioning system switching method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the positioning system switching method of the present application.

[0046] In this embodiment, the positioning system switching method includes steps S10 to S40:

[0047] Step S10, obtaining first navigation information.

[0048] It should be noted that obtaining the first navigation information means that the mobile phone uses the GPS positioning system by default to obtain the current location information in the normal working mode. Specifically, the GPS receiver of the mobile phone will first search and lock the signals of at least four GPS satellites, and calculate the distance by measuring the propagation time of the signals received from each satellite. Using this distance information, the mobile phone can use trilateral measurement or quadrilateral measurement to determine its own three-dimensional coordinates (longitude, latitude and altitude). In addition, GPS satellites also provide accurate time information, which is very important for calculating the position. Once this information is obtained, the mobile phone will combine it with the map data to display the user's current location and navigation path. However, in certain specific environments, such as urban canyons with high-rise buildings, densely forested areas or indoors, GPS signals may be interfered with or attenuated, resulting in inaccurate positioning or the inability to obtain effective positioning information.

[0049] Step S20: when the first navigation information does not meet the preset positioning requirement, obtain the second positioning system attribute and the second positioning system configuration.

[0050] It should be noted that when the first navigation information does not meet the preset positioning requirements, the current GPS positioning accuracy and availability are automatically detected. The above-mentioned preset positioning requirements include positioning accuracy, response time, signal coverage, continuous availability and special requirements in emergency situations. The above-mentioned second positioning system attributes include at least one of the satellite signal strength, number of satellites, positioning accuracy and timestamp. The above-mentioned second positioning system configuration includes at least one of the second system's service mode, positioning mode, signal processing parameters and user-defined settings. If it is found that the positioning information provided by GPS has a large error or cannot obtain effective positioning, the backup Beidou positioning system is started. First, check the properties and configuration of the Beidou positioning system to ensure that it meets the preset power-on requirements. This includes verifying whether the hardware status, software version and configuration parameters of the Beidou positioning system are normal. Read the system global properties to determine whether the Beidou positioning system has been enabled. When the first navigation information does not meet the preset positioning information, a touch command is generated by clicking the user setting menu or by clicking the power button for a preset number of times; when a touch command is received, the second positioning system properties and the second positioning system configuration are obtained. The specific implementation code is:

[0051]

[0052] If not enabled, the system will enable the Beidou positioning system through the settings menu or shortcut keys (for example, clicking the power button five times in a row). The specific implementation code is:

[0053]

[0054] Step S30: When the second positioning system attributes and the second positioning system configuration both meet the preset power-on requirements, a control instruction is sent to start the second positioning system.

[0055] It should be noted that when the second positioning system properties and the second positioning system configuration meet the preset power-on requirements, the control command is sent and the second positioning system, namely the Beidou positioning system, is turned on. Specifically, the system global property persist.vendor.ext_gps_support is first read to determine whether the Beidou positioning system is enabled. If the property value is true, it means that the Beidou positioning system is enabled; otherwise, the property will be set by calling the SystemProperties.set("persist.vendor.ext_gps_support","true") method to activate the Beidou positioning system.

[0056] Further, when the second positioning system attribute is a preset value and the calling interface service in the second positioning system configuration is turned on and the preset interface is in an upper voltage state, a control instruction is sent to control the power-on of the second positioning system chip. Specifically, register the configuration of the Beidou positioning system. This step includes initializing the Beidou positioning service interface IGnss_V2_1 or IGnss_V2_0 and checking whether these interfaces are available. The specific code implementation is as follows:

[0057] if(!android::base::GetBoolProperty("persist.vendor.ext_gps_support",false)){

[0058] gnssHal_V2_1=IGnss_V2_1::getService();

[0059] if(gnssHal_V2_1!=nullptr){

[0060] gnssHal_V2_0=gnssHal_V2_1;

[0061] gnssHal_V1_1=gnssHal_V2_1;

[0062] gnssHal = gnssHal_V2_1;

[0063] return;

[0064] }

[0065] }

[0066] gnssHal_V2_0=IGnss_V2_0::getService();

[0067] if(gnssHal_V2_0!=nullptr){

[0068] gnssHal_V1_1=gnssHal_V2_0;

[0069] gnssHal = gnssHal_V2_0;

[0070] ALOGD("gnssHal 2.1was null,trying 2.0upgradeState=%d";

[0071] upgradeState);

[0072] return;

[0073] }First try to obtain the IGnss_V2_1 interface. If successful, assign it to the gnssHal variable and return. If the IGnss_V2_1 interface is not available, try to obtain the IGnss_V2_0 interface. If the IGnss_V2_0 interface is also successfully obtained, it is also assigned to the gnssHal variable and the log information is recorded.

[0074] Furthermore, after the second positioning system chip is powered on, the second positioning system is turned on. Specifically, after the interface registration is completed, the power-on method of the Beidou chip is further called, and the IOCTL pin is pulled high through the reserved interface to put the Beidou chip into working state. The specific power-on method is implemented as follows:

[0075]

[0076] }First, open the device file / dev / rtk_gps, and then send the command IOCTL_OPEN_RTK_POWER through the ioctl system call to power on the Beidou chip. If the device file fails to open or the ioctl call fails, the function will return the corresponding error code. Through the above steps, ensure that the Beidou positioning system can be successfully started and start to provide high-precision positioning services. Once the Beidou positioning system is successfully started, the system will switch the navigation mode to Beidou navigation mode and obtain the second navigation information, so as to provide more reliable and accurate positioning services in the case of GPS positioning failure or inaccuracy, and improve the user's navigation experience.

[0077] Step S40: switch the navigation mode to the second navigation mode, and obtain second navigation information.

[0078] It should be noted that the process of switching the navigation mode to the second navigation mode and obtaining the second navigation information is performed after the Beidou positioning system is started and successfully powered on. When it is detected that the Beidou positioning system is ready, a control command will be sent to switch the navigation mode from GPS to Beidou. Specifically, the internal status flag is updated to notify all related navigation services and applications that the Beidou positioning system is currently being used.

[0079] First, start the Beidou positioning service by calling the method of the Beidou positioning service interface. For example, call the gnssHal->start() method to start the Beidou positioning service to ensure that the Beidou chip starts receiving satellite signals and performing positioning calculations. Next, the system will periodically obtain the latest positioning information from the Beidou positioning service interface. This is usually achieved by registering a callback function. When the Beidou positioning service has new positioning data, the callback function will be called to pass the data to the application. For example, the system can register an IGnssCallback callback object. When the Beidou positioning service has new positioning data, the onLocationChanged method of the callback object will be called. The specific implementation is as follows:

[0080]

[0081] MyGnssCallback*myCallback=new MyGnssCallback();

[0082] gnssHal->setCallback(myCallback);

[0083] The MyGnssCallback class inherits from IGnssCallback and overrides the onLocationChanged method. When the Beidou positioning service has new positioning data, the onLocationChanged method will be called to process and update the new positioning information. The system will pass the new positioning information to the user interface or other related applications to display the user's current location and navigation path.

[0084] In addition, the map and route information in the navigation app is updated to ensure that users can see the latest navigation instructions. This includes recalculating the navigation route, updating navigation prompts, and adjusting the map display. For example, the navigation app will recalculate the optimal route based on the new positioning information and display the new navigation route and direction instructions on the map.

[0085] This embodiment provides a method for switching a positioning system, by acquiring first navigation information, when the first navigation information does not meet the preset positioning requirements, acquiring the second positioning system attributes and the second positioning system configuration, when the second positioning system attributes and the second positioning system configuration both meet the preset power-on requirements, sending a control instruction, turning on the second positioning system, switching the navigation mode to the second navigation mode, and acquiring the second navigation information. When GPS positioning is inaccurate, switching to other positioning systems ensures positioning accuracy, improves positioning reliability, and meets positioning requirements in different scenarios.

[0086] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 The positioning system switching method step S40 also includes steps S401 to S403:

[0087] Step S401, detecting the current navigation mode to determine whether it is the second navigation mode.

[0088] It should be noted that the built-in navigation mode recognition algorithm monitors and analyzes the currently activated navigation system in real time to determine whether it is the second navigation mode, namely the Beidou navigation mode. This process involves real-time monitoring of satellite signals, evaluation of signal quality, and inspection of system configuration.

[0089] Further, step S401 also includes: when the current navigation mode is not the second navigation mode, performing a switching operation to switch the navigation mode to the second navigation mode. Specifically, when it is detected that the current navigation mode is not the second navigation mode, a series of preset operation processes will be automatically triggered. First, evaluate whether the navigation information provided by the first navigation mode (such as GPS) meets the preset positioning requirements, which may include key parameters such as positioning accuracy, signal strength, and response time. If the first navigation mode fails to meet these requirements, the properties and configuration information of the second navigation system (Beidou system) will be automatically obtained to determine whether the preset power-on requirements are met. Once it is confirmed that the properties and configuration of the second navigation system meet the requirements, send a control instruction, turn on the second navigation system, and make necessary configuration adjustments to ensure seamless switching to the second navigation mode.

[0090] Step S402: when the current navigation mode is the second navigation mode, configure the second positioning system parameters.

[0091] It should be noted that when it is detected that the current navigation mode has been switched to the second navigation mode, namely the Beidou navigation mode, the operation of configuring the parameters of the second positioning system will be automatically performed to optimize the positioning performance. These operations include adjusting the satellite signal reception parameters to improve the signal quality, adjusting the positioning algorithm parameters according to the characteristics of the Beidou system to improve the positioning accuracy and speed, and allowing users to customize the settings according to their personal preferences, such as positioning frequency and energy consumption balance. At the same time, the configuration is dynamically adjusted according to environmental changes such as weather and building occlusion to ensure that the best performance can be maintained in various scenarios. In addition, compatibility settings will be made to ensure that other navigation systems, such as GPS, can be quickly switched when needed. The performance indicators of the Beidou system, such as positioning accuracy and signal stability, are continuously monitored, and the configuration is automatically adjusted according to these indicators to maintain the best positioning effect. During the configuration process, the user's location information security and privacy protection are also emphasized, and necessary measures are taken to ensure the security of data transmission and the confidentiality of user privacy.

[0092] Step S403: communicate with the second positioning system satellite through the second positioning system parameters to obtain second navigation information.

[0093] It should be understood that the above-mentioned second positioning system satellites refer to Beidou positioning system satellites, and communicating with Beidou satellites through the second positioning system parameters is a key step in achieving high-precision positioning. Configured parameters such as satellite selection strategy, signal processing algorithm and time synchronization settings will be used to establish a stable data link with Beidou satellites. These parameters ensure the effective reception and processing of signals, and improve the accuracy and reliability of positioning information.

[0094] During the communication process, ephemeris data from Beidou satellites are received, which describe the precise position and motion trajectory of the satellites, and are essential for calculating the position of ground receivers. At the same time, time information is obtained to calibrate the device time and improve the accuracy of positioning solutions. In addition, the navigation message contains various parameters used for positioning calculations, such as the health of the satellites, ionospheric delay parameters, etc., which are essential for improving positioning accuracy and reliability. These navigation information will be processed in real time and combined with the signals from the ground receivers to calculate the precise position, speed and time information. This process not only improves the accuracy of positioning, but also enhances the robustness of the system, enabling it to provide continuous and stable positioning services in various environmental conditions, such as urban canyons, indoors or in mountainous areas where GPS signals are weak.

[0095] Further, after step S403, it also includes: calculating according to the second navigation information, obtaining the position, speed and time, displaying the position, speed and time on the user interface, and adjusting the navigation route for navigation. Specifically, based on the second navigation information, i.e., Beidou navigation information, the user's precise position, speed and time will be calculated and determined. These calculations involve steps such as decoding of satellite signals, time synchronization, and position solution to ensure high accuracy and reliability of the results. The calculated position information will include longitude and latitude, altitude, etc., the speed information will cover the user's moving speed and direction, and the time information will provide accurate current time, which is particularly important for application scenarios that require accurate time synchronization. And this information is intuitively displayed on the user interface, such as location markers, speed dials and time displays on the map. Real-time updates of position and speed will help users understand their mobile status, while time display is essential for time-sensitive tasks. In addition, according to the user's mobile status and preset destination, the navigation route is intelligently adjusted to provide optimal path suggestions. This includes avoiding traffic congestion areas, selecting the fastest route, or selecting a route based on user preferences. During navigation, the system also provides voice prompts and visual guidance to ensure that users can easily follow the navigation instructions and reach their destination safely. In this way, the system not only improves the accuracy and efficiency of navigation, but also greatly enhances the user experience.

[0096] This embodiment detects the current navigation mode to determine whether it is the second navigation mode. When the current navigation mode is the second navigation mode, the second positioning system parameters are configured, and the second positioning system satellite is communicated with through the second positioning system parameters to obtain the second navigation information. Through intelligent detection and switching to Beidou mode and configuring parameters, the navigation information is obtained through communication, the positioning accuracy is improved, and the navigation reliability is enhanced.
