Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart illustrating a positioning module-based control method according to an embodiment of the present application, where the method may be executed by a positioning module-based control apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a mobile terminal. As shown in fig. 1, the method includes:
Wherein the acceleration sensor does not include arithmetic logic therein.
For example, the mobile terminal in the embodiment of the present application may include a mobile device such as a mobile phone and a tablet computer, which is provided with a GNSS positioning module (referred to as a GNSS module for short). The specific type of the GNSS module is not limited in the embodiments of the present application, and may include a Global Positioning System (GPS), a beidou satellite navigation System, a GALILEO satellite navigation System (GALILEO), and the like.
The GNSS module consumes a large amount of power in the positioning process, and the endurance time of the mobile terminal is influenced. Generally, a mobile terminal may be loaded with a plurality of Location Based Service (LBS) applications, such as an electronic map application (e.g., a hundred degree map), a takeout application (e.g., a mei juan takeout), a social contact application (e.g., a Wechat application), an information Service application (e.g., a popular comment), and a travel application (e.g., a travel guide). When the LBS application needs to use the positioning service, a call request to the GNSS module is sent (i.e., the LBS application initiates a positioning request of a GNSS positioning mode), if the call request is agreed (i.e., if the positioning request is agreed), the GNSS module is started and in a normal working mode, satellite signals are searched and other related data used for positioning are acquired, further, the position information (also called positioning information) of the mobile terminal is calculated and provided for the LBS application, the LBS application provides richer services to the user according to the position information, and when the LBS application cancels the call, the GNSS module is closed. Whether the working state of the GNSS module is reasonable depends on whether the LBS application reasonably uses the GNSS module, and the mobile terminal in the related art does not manage and control the working state of the GNSS module in the LBS application calling state, so that the GNSS module has the condition of excessive power consumption caused by improper use.
In the embodiment of the application, in order to reasonably control the operation of the GNSS module, the operation mode of the GNSS module may be determined according to the motion state of the mobile terminal. At present, with the rapid development of sensor technology, the variety of sensors is increasing, the functions are more and more powerful, and the cost is higher and higher. In the related art, a mobile terminal generally detects a motion state of the mobile terminal by using a high-level sensor having arithmetic logic, such as a gyroscope, or detects a motion state of the mobile terminal by adding a sensor hub (sensor hub) in combination with the sensor, the sensor hub has arithmetic capability and can calculate and analyze data generated by the sensor so as to obtain a detection result of the motion state, and the high-level sensor or the sensor hub, such as the gyroscope, can transmit a final detection result to a processor in the mobile terminal so that the processor can perform a corresponding operation according to the detection result. However, for some low-end mobile terminals, in order to control the manufacturing cost, it is not considered to add a high-level sensor or a sensor hub having an arithmetic logic, such as a gyroscope, so that these mobile terminals cannot detect the motion state of the mobile terminal based on the existing method.
An Application Processor (AP) is the most important Processor in the mobile terminal, and the system operation and the Application program operation of the mobile terminal depend on the AP. In the embodiment of the application, acceleration data in the horizontal direction generated by a common acceleration sensor without arithmetic logic is directly obtained through the AP, and operation, subsequent identification and other operations are performed based on the obtained sensor raw data, so that the detection of the motion state of a high-level sensor such as a gyroscope and a low-end mobile terminal of the sensorhub can be realized, and the work of the GNSS module is reasonably controlled based on the motion state. Since the change of the mobile terminal positioning information is caused by the movement in the horizontal direction, in the embodiment of the application, only the acceleration data in the horizontal direction is acquired, and the data acquisition amount and the calculation amount can be reduced, thereby reducing the power consumption.
And 102, performing integral operation on the acceleration data acquired within the preset duration through the AP.
For example, the integration operation may be time domain integration, frequency domain integration, primary integration, or secondary integration, and the embodiment of the present application is not limited. The result of the integration operation may be a velocity, a displacement, or data related to the velocity or the displacement in the horizontal direction, and the displacement in the horizontal direction will be described as an example. The embodiment of the present application does not limit the details of the specific operation. To facilitate subsequent determination, the result of the integration operation may be data in absolute value form.
The specific value of the preset time period may be set according to actual requirements, and may be 5 seconds, for example. Optionally, the preset duration may be determined according to a result of predicting the user behavior by the mobile terminal. Illustratively, counting or learning the motion trail of the mobile terminal by taking a preset counting period (such as one day) as a unit, and if it is determined according to a counting result or a learning result that a first probability that the period of the current time of the user is in a static state is higher than a first preset probability threshold (such as 80%), setting the preset time length as a first preset time length (such as 5 seconds); if the first probability is lower than or equal to a first preset probability threshold, setting the preset time length to a second preset time length (for example, 10 seconds) which is longer than the first preset time length so as to prolong the integration time and improve the accuracy of the motion state detection result. It can be understood that more preset probability thresholds and more preset durations can be set, so as to dynamically adjust the preset durations.
When the mobile terminal is in a stationary state or a slow-moving state, the position of the mobile terminal is almost unchanged or slightly changed, and if the GNSS module is in a normal operating mode, satellite signal search and other related positioning operations are performed continuously, which causes higher power consumption and affects the endurance time of the mobile terminal.
Exemplarily, when the operation result is smaller than a first preset threshold, determining that the mobile terminal is in a static state; and when the operation result is greater than or equal to the first preset threshold and smaller than a second preset threshold, determining that the mobile terminal is in a slow-speed traveling state. The first preset threshold and the second preset threshold may be related to an integral operation mode, and when the operation result is a speed, the first preset threshold and the second preset threshold are speed values, such as 0.1 m/s and 1 m/s, respectively; when the operation result is displacement, the first preset threshold and the second preset threshold are displacement values, such as 0.5 meter and 5 meters, respectively. The specific values of the first preset threshold and the second preset threshold are not limited in the embodiments of the present application.
And 104, controlling the GNSS module to enter a low-power-consumption working mode when the mobile terminal is determined to be in the first preset state.
In the embodiment of the application, when the mobile terminal is determined to be in a static state or a slow-speed traveling state, if the GNSS module still keeps an efficient normal operation state, the power consumption is high, so that the GNSS module can be controlled to enter a low-power-consumption working mode, unnecessary positioning operation is omitted, and the system power consumption of the mobile terminal is reduced.
In the embodiment of the present application, specific implementation manners for controlling the GNSS module to enter the low power consumption operating mode may be various, and the embodiment of the present application is not limited. For example, the GNSS module may be turned off, for example, the power supply to the GNSS module is stopped, which is advantageous in that the positioning function may be completely turned off to avoid the power consumption generated by the GNSS module. The GNSS module can be controlled to enter a dormant state, satellite signal searching and other related operations can be stopped, and the GNSS module stops working, so that power consumption of the GNSS module caused by positioning can be reduced, and the GNSS module can be quickly restored to a normal working state when positioning is needed. The GNSS module may also be controlled to reduce the frequency of performing positioning related operations, for example, the frequency of searching for satellite signals may be reduced, and the frequency of reporting location information to the application layer may also be reduced. The method may further control a correlator in the GNSS module to close a preset number of channels, and control the correlation unit to stop processing signals or data corresponding to the closed channels, where the preset number may be a fixed value or a variable determined according to an actual situation. The advantage of this arrangement is that the positioning function is still available, and when the mobile terminal moves, the positioning information can be updated in time, and at the same time, the power consumption can be reduced. In addition, a low power consumption working mode can be realized by adopting a mode of reducing positioning precision and the like, and the application is not limited.
In order to facilitate understanding of the technical solutions of the embodiments of the present application, the correlator is briefly described below. The GNSS module in the mobile terminal includes a radio frequency receiving front end, a correlator and a baseband calculation control unit, where the correlator generally includes multiple channels, usually 12 channels and 20 channels (the total number of channels is not limited in the embodiment of the present application), and all channels in the correlator participate in operation during the operation of the GNSS module. After the radio frequency signal of the satellite signal is received by the antenna, the radio frequency signal is amplified, filtered, mixed and sampled by the radio frequency receiving front end and then is sent to the correlator for correlation operation. In the correlation operation process, a signal is multiplied by a local reproduction carrier generated by a correlator to realize demodulation, the signal is divided into an in-phase path and an orthogonal-phase path after the carrier is stripped, then the in-phase path and the orthogonal-phase path are multiplied by the local reproduction carrier respectively to realize de-spreading, and the data is sent to a baseband resolving control unit to be processed by a baseband after integral dump, so that satellite navigation messages and positioning information are finally obtained. Meanwhile, the baseband resolving control unit feeds back the carrier frequency control word and the code frequency control word calculated by the carrier tracking loop and the code tracking loop to a numerically controlled oscillator in the correlator in real time, so that the real-time acquisition and tracking of the correlator loop to the satellite signal are realized. It can be seen that each channel in the correlator needs a lot of operations, which inevitably results in large power consumption. In the embodiment of the application, when the GNSS module is controlled to enter the low power consumption operating mode, the AP may send a preset control instruction to the GNSS module, so that the GNSS module closes the channels of the preset number of correlators according to the preset control instruction, and controls the correlation unit to stop processing the signal or data corresponding to the closed channel. The correlation unit may include a data preprocessing and interrupt control unit, a digitally controlled carrier oscillator, a C/a code (coarse ranging code) generator, a digital multiplier and integral dump unit, and an epoch counter. The power consumption reduction mode can greatly reduce the power consumption generated by the correlator, and experiments prove that the power consumption of the GNSS module can be effectively reduced by reducing the number of logic gates contained in the GNSS module from 50 ten thousand to 10 ten thousand by adopting the mode.
According to the control method based on the positioning module, when a GNSS module in a mobile terminal is in a normal working mode due to being called by LBS application, acceleration data in the horizontal direction generated by an acceleration sensor is obtained through an AP, wherein the acceleration sensor does not contain arithmetic logic; performing integral operation on acceleration data acquired within a preset time length through the AP; determining whether the mobile terminal is in a first preset state according to an operation result, wherein the first preset state comprises a static state and/or a slow-speed traveling state; and when the mobile terminal is determined to be in the first preset state, controlling the GNSS module to enter a low-power-consumption working mode. By adopting the technical scheme, the motion state of the mobile terminal can be detected by matching the AP and the acceleration sensor without arithmetic logic under the condition of saving the manufacturing cost of the mobile terminal, and the working mode of the GNSS module can be reasonably adjusted according to the motion state.
In some embodiments, the controlling the GNSS module to enter the low power operation mode when it is determined that the mobile terminal is in the first preset state includes: when the mobile terminal is determined to be in the first preset state, judging whether a current scene is suitable for the GNSS module to work; and if not, controlling the GNSS module to enter a low-power-consumption working mode. The mobile terminal can be converted into a motion state with a fast change position at any time when the mobile terminal is in a static state or a slow-speed traveling state, the current scene where the mobile terminal is located can be judged for ensuring timeliness of a positioning function, if the current scene is not suitable for the GNSS module to work, even if the GNSS module is in a normal working mode, the GNSS module is probably unable to be positioned, or a positioning result is not credible, and therefore the GNSS module can be controlled to enter a low-power-consumption working mode, such as the GNSS module is turned off.
For example, scenarios unsuitable for GNSS module operation may include indoor environments, or other closed or semi-closed environments, such as inside tunnels and under viaducts, etc. Optionally, the determining whether the current scene is suitable for the GNSS module to work may include determining whether the current scene is an indoor scene, and if the current scene is an indoor scene, determining that the current scene is not suitable for the GNSS module to work. There are many ways to determine whether the scene is an indoor scene, and the embodiment of the present application is not particularly limited. For example, a current position is located through a GNSS module or other locating methods (such as a base station locating method or a network locating method), corresponding weather information is obtained according to the current position, weather-related data is collected through a preset sensor in the mobile terminal, the collected weather-related data is compared with the weather information, and whether the mobile terminal is in an indoor environment is determined according to a comparison result. Further, the comparing the collected weather-related data with the weather information includes: acquiring sampling values of preset items in the collected weather related data; comparing the sampling value with a standard value corresponding to the preset item in the weather information; wherein the preset items comprise any one or more of air temperature, humidity, illumination intensity, ultraviolet intensity, wind power and air quality. Taking the preset items including air temperature as an example, the air temperature value contained in the weather information is a standard value of the outdoor temperature, and the mobile terminal can acquire the environmental temperature through a built-in temperature sensor as a sampling value of the air temperature. Generally, because the existence of the isolation effect of wall for indoor outer temperature has the difference, especially in summer and winter, or outdoor weather is when comparatively bad (for example overcast and rainy day or wind is big etc.), indoor outer temperature difference is great, because weather is hot or when colder, usable air conditioner or heating equipment etc. adjust the temperature, can make indoor temperature be different from outdoor temperature, if the sampling value is great with the standard value difference, can explain that mobile terminal is in indoor environment. For example, the current positions of the positioning are tianjin city and the equal district, the temperature obtained from tianjin city and the equal district is 4 degrees celsius, the standard value is 4, and if the mobile terminal is indoors, the indoor environment is warmer, the sampling value may be 20, and it can be determined that the mobile terminal is indoors if the difference between the sampling value and the standard value is large.
For example, whether the current scene is suitable for the GNSS module to work can be further determined according to the number of satellites currently searched by the GNSS module and the satellite signal strength. Optionally, it is determined whether the number of satellites in the satellite information currently acquired by the GNSS module satisfies the number required for positioning, and whether the signal strength of the satellites satisfies the strength required for positioning, and if any one of the satellite strengths does not satisfy the strength required for positioning, it may be determined that the current scene is not suitable for the GNSS module to work. Specifically, when it is determined that the number of satellites in the satellite information currently acquired by the GNSS module is smaller than a preset minimum satellite number, or the CN value of the satellite signal is smaller than a preset signal intensity threshold, it may be determined that the current scene is not suitable for the GNSS module to work. Wherein, the CN value refers to the power ratio of the carrier to the noise, and is used to measure the strength of the satellite signal. Optionally, the minimum satellite number is 4, and the preset signal strength threshold is 8.
Exemplarily, the satellite information acquired by the GNSS module may be acquired at regular time, and when the currently acquired satellite information is the same as the satellite information acquired last time, a value of a preset environmental parameter is added by 1, and an initial value of the environmental parameter is 0; and when the value of the environmental parameter obtained within the preset time is larger than a preset environmental parameter threshold value, determining that the current scene is not suitable for the GNSS module to work. Further, when the currently acquired satellite information is different from the satellite information acquired last time, if the strength value of the satellite signal in the currently acquired satellite information is smaller than a preset signal strength threshold value and the number of satellites in the currently acquired satellite information is smaller than a preset value, adding 1 to the value of the environment parameter; otherwise, determining that the current scene is suitable for the GNSS module to work.
In some embodiments, whether the current scenario is suitable for the GNSS module to operate may be determined as follows. Fig. 2 is a schematic flowchart of a process for detecting whether a current scene is suitable for a GNSS module to work according to an embodiment of the present invention, and as shown in fig. 2, the process for detecting whether a current scene is suitable for a GNSS module to work specifically includes the following steps:
in step 201, the initialization environment parameter variable STimer is equal to 0.
And step 205, adding 1 to the value of STImer.
The specific value of MAX _ NUM is not limited, and may be, for example, 5.
For example, the GNSS module can perform positioning at this time, so that the current scenario is suitable for the GNSS module to work.
And step 208, determining that the current scene is not suitable for the GNSS module to work.
Through the above steps shown in fig. 2, it can be accurately determined whether the current scene is suitable for the GNSS module to work.
In some embodiments, the GNSS module may be controlled to enter the low power operation mode in different manners according to actual situations. Before the controlling the GNSS module to enter the low power consumption operation mode, the method further includes: acquiring type information of the LBS application; the controlling the GNSS module to enter a low power consumption operating mode includes: and determining a target mode for controlling the GNSS module to enter a low-power-consumption working mode according to the type information and the state of the mobile terminal, and controlling the GNSS module to enter the low-power-consumption working mode according to the target mode. The advantage of setting up like this is, under the circumstances of the location demand of giving consideration to different types of LBS application, the power consumption mode that falls of abundant GNSS module.
The type information of the LBS application may include an electronic map application (such as a Baidu map, etc.), a traffic application (such as a drip trip, a Mobai bicycle, etc.), a takeout application (such as a beauty group takeout, etc.), a social application (such as a WeChat, etc.), an information service application (such as a popular comment, etc.), a travel application (such as a travel, etc.), a video application (such as an Archie art), a game application (such as a Royal of a King worker), a text application (such as an office), etc., and may be classified according to different classification policies, where different classification policies may correspond to different classification results. The type information of the LBS application may reflect the level of the positioning accuracy requirement of the application program. For example, the navigation application program has higher requirement on positioning accuracy, and the applications such as Mobai bicycle and automobile have higher requirement on positioning accuracy. These applications need to accurately obtain not only the city in which the user is located, the various areas in the city, street information in the areas, but also latitude and longitude information. And the information service application program, the game application program, the camera application program and other application programs have lower requirements on positioning accuracy. The application programs with low requirements on positioning accuracy only acquire the city where the user is located or each area in the city, and can provide better service for the user.
Further, the determining a target mode for controlling the GNSS module to enter the low power consumption operating mode according to the type information and the state of the mobile terminal includes: when the type information is a first preset type and the mobile terminal is in a static state, determining that a target mode for controlling the GNSS module to enter a low-power-consumption working mode is to close the GNSS module; when the type information is a second preset type and the mobile terminal is in a static state, determining that a target mode for controlling the GNSS module to enter a low-power-consumption working mode is to control the GNSS module to enter a dormant state; when the type information is a first preset type and the mobile terminal is in a slow-speed traveling state, determining that a target mode for controlling the GNSS module to enter a low-power-consumption working mode is to control the GNSS module to close channels with a first preset number of correlators and control a related unit to stop processing signals or data corresponding to the closed channels; and when the type information is a second preset type and the mobile terminal is in a slow-speed traveling state, determining that a target mode for controlling the GNSS module to enter the low-power-consumption working mode is to control the GNSS module to close channels with a second preset number of correlators, and controlling the correlation unit to stop processing signals or data corresponding to the closed channels.
The positioning accuracy required by the LBS application corresponding to the first preset type is smaller than the positioning accuracy required by the LBS application corresponding to the second preset type, and the first preset number is larger than the second preset number. The advantage of this arrangement is that it can be combined with the specific motion state that needs power reduction and the requirement of the application program for positioning accuracy to determine which power reduction mode is adopted. It is to be understood that, in the third and fourth cases, the manner of controlling the correlator in the GNSS module to close the preset number of channels and controlling the correlation unit to stop processing the signals or data corresponding to the closed channels may be replaced by other manners, such as controlling the GNSS module to reduce the frequency of performing the positioning correlation operation as described above.
For example, the first preset type and the second preset type may be set by a default of the system or may be set autonomously by the user. When the system is set by default, the mobile terminal can also count or learn the historical use habits of the user sample and the corresponding scene information to generate and formulate the historical use habits. For example, the embodiment of the present application may further include: counting or learning historical habit data of different types of application programs used by a user according to a preset period; and determining a first preset type and a second preset type according to the statistical result or the learning result. As described above, different classes of LBS applications have different requirements on the positioning accuracy, and the LBS application type with low requirement on the positioning accuracy may be classified into a first preset type, and the LBS application type with high requirement on the positioning accuracy may be classified into a second preset type.
Specifically, the historical habit data includes at least one of the number of times of calling a map screen, the frequency of refreshing the map screen, the number of times of manually correcting the position, and the number of times of actively starting the GNSS positioning function.
