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:
The embodiment of the present application does not limit the specific type of the GNSS module, and may include a Global Positioning System (GPS), a beidou satellite navigation System, a galileo satellite navigation System (GA L I L EO), and the like.
Generally, a mobile terminal is loaded with a plurality of applications Based on location services (L position Based services, L BS), such as electronic map applications (e.g., hundred degree maps), takeaway applications (e.g., takeaway from the U.S. Pat. etc.), social applications (e.g., WeChat, etc.), information Service applications (e.g., popular comment, etc.), travel applications (e.g., travel), etc. when a L BS application needs to use a positioning Service, a request for invoking the GNSS module (i.e., the positioning request of the GNSS L BS application initiates a positioning mode) is sent, if the request is agreed (i.e., if the positioning request is agreed), the GNSS module is started and in a normal operating mode, a satellite signal is searched and other related data for positioning are obtained, and then location information (also referred to as positioning information) of the mobile terminal is calculated, the location information is provided to the BS 39L BS application, the GNSS module provides a richer Service to the user according to the location information, and when the application invokes, the GNSS module is shut down, and thus no more relevant power consumption of the GNSS module is caused by the relevant operating condition that the GNSS module may be used.
102, acquiring current use scene information, and judging whether the use scene information meets a preset power consumption reduction condition.
In the embodiment of the application, according to different use scenes, a power consumption reduction condition is preset, and further in the process that the GNSS module is called by L BS application, whether the GNSS module can be controlled to enter a low-power-consumption working mode or not can be judged according to the obtained current use scene information.
And 103, controlling the GNSS module to close channels with preset number of correlators when the service scene information is judged to meet the preset power consumption reduction condition so as to reduce the power consumption generated by the GNSS module.
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 power consumption of the GNSS module needs to be reduced, the GNSS module can be controlled to close a certain number of channels in the correlator, so that the power consumption generated in the working process of the correlator is reduced, and further, the power consumption of the GNSS module is reduced. The preset number may be a preset fixed value (for example, a product of the total number of channels and a preset proportional value, the preset proportional value may be, for example, 0.5 or 0.3, and the present embodiment is not limited), or may be a variable determined according to an actual situation. Furthermore, when the preset number of channels are closed, the related unit can be controlled to stop processing the signals or data corresponding to the closed channels. 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, the GNSS module in the mobile terminal is detected to be in a normal working mode due to the fact that the GNSS module is called by the L BS application, the current use scene information is obtained, and when the use scene information is judged to meet the preset power consumption reduction condition, the GNSS module is controlled to close the channels with the preset number of the correlators, so that the power consumption generated by the GNSS module is reduced.
In some embodiments, the usage scenario information includes the number of satellites searched by the GNSS module and/or satellite signal strengths, and the determining whether the usage scenario information satisfies a preset power consumption reduction condition includes: judging whether the number of the satellites is smaller than a preset number threshold value, and if so, determining that the use scene information meets a preset power consumption reduction condition; and/or judging whether the satellite signal intensity is smaller than a preset intensity threshold value, and if so, determining that the use scene information meets a preset power consumption reduction condition. The number of satellites and the signal strength of the satellites may be included in the satellite information obtained by the GNSS module. The preset number threshold may be determined according to the number required for positioning, for example, the GPS module requires at least 4 satellites for positioning, and the preset number threshold may be 4, or may be a value less than 4, such as 1, 2, or 3. The satellite signal strength can be represented by a CN value, which refers to the power ratio of the carrier to the noise and is used to measure the strength of the satellite signal. The preset signal strength threshold may be 8. In the embodiment of the application, the judgment can be performed only based on the number of satellites, or only based on the strength of the satellite signal, the number of satellites and the strength of the satellite signal can be acquired simultaneously, and when any one of the number of satellites and the strength of the satellite signal is smaller than a corresponding threshold value, it is determined that the use scene information meets the preset power consumption reduction condition. The advantage of such an arrangement is that, when the GNSS module is in the normal operating mode, the GNSS module needs to continuously search for satellite signals, and whether the GNSS module can currently realize positioning can be quickly and accurately determined according to the satellite signals.
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 using scene information meets a preset power consumption reduction condition. 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 using scene information does not meet the preset power consumption reduction condition.
In some embodiments, it may be determined that the preset power reduction condition is satisfied using the scene information as follows. Fig. 2 is a schematic flowchart of a process for determining whether usage scenario information satisfies a preset power consumption reduction condition according to an embodiment of the present application, and as shown in fig. 2, the process includes the following steps:
in step 201, the initialization environment parameter variable STimer is equal to 0.
And 204, judging whether the CN value of the satellite signals in the currently acquired satellite information is smaller than a preset signal strength threshold MIN _ VA L UE and the number of the satellites is smaller than a preset minimum satellite number MIN _ NUM, if so, executing a step 205, and otherwise, executing a step 207.
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 usage scenario information does not satisfy the preset power consumption reduction condition.
And step 208, using the scene information to meet a preset power consumption reduction condition.
Through the above steps shown in fig. 2, it can be accurately determined whether the usage scenario information satisfies the preset power consumption reduction condition.
In some embodiments, the determining whether the usage scenario information satisfies a preset power consumption reduction condition includes: acquiring weather information corresponding to an area where the mobile terminal is located; and comparing the weather related data with the weather information, judging whether the mobile terminal is in an indoor environment according to a comparison result, and if so, determining that the service scene information meets a preset power consumption reduction condition. The advantage of setting up like this is that can accurately judge whether mobile terminal is in indoor with the help of the weather condition, and the indoor environment is unsuitable GNSS module work, so can think to satisfy and predetermine the condition of reducing the power consumption. Specifically, the area where the mobile terminal is located may be determined according to the positioning information of the GNSS module before the preset time period, or the current position of the mobile terminal may be located in a base station positioning manner or a WiFi positioning manner, so as to determine the area where the mobile terminal is located. The mobile terminal can access the weather server and inquire the corresponding current weather information according to the area. Specifically, the comparing the collected weather-related data with the weather information may include: 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. And when the difference value of the sampling value and the corresponding standard value meets the indoor judgment condition, determining that the mobile terminal is in the indoor environment. Taking the temperature as an example, 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 comparatively cold, 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.
In some embodiments, the preset items may be determined according to values of various items in the weather information. The method has the advantages that the mobile terminal is pointed to acquire the weather related data, so that the data volume acquired by the mobile terminal can be reduced, the judging steps are reduced, and the judgment of indoor and outdoor environments is accelerated. For example, an item favorable for rapidly judging the indoor and outdoor environments can be estimated in advance according to the current numerical values of the items contained in the weather information, and the estimated item is used as a preset item, so that the purpose of screening the preset item is achieved. For example, if the temperature in the weather information is-10 degrees celsius, which indicates that the outdoor environment is very cold, the difference between the indoor temperature and the outdoor temperature is very large, the temperature can be determined as a preset item, the mobile terminal is instructed to acquire the temperature through the temperature sensor, and then the mobile terminal can be quickly judged to be in the indoor environment according to the temperature difference. For another example, the temperature in the weather information is 25 degrees celsius, which indicates that the outdoor temperature is moderate, and then the difference between the indoor temperature and the outdoor temperature may be small, which is not beneficial to the determination, and the item with unexpected temperature can be determined as the preset item.
In some embodiments, the determining whether the usage scenario information satisfies a preset power consumption reduction condition includes: and judging whether the current WiFi hotspot information list contains a preset WiFi hotspot, if so, determining that the use scene information meets a preset power consumption reduction condition, wherein the preset WiFi hotspot comprises a WiFi hotspot in an indoor environment. The method has the advantages that whether the mobile terminal is in the indoor environment or not can be quickly judged based on the current WiFi hotspot information list, and whether the preset power consumption reduction condition is met or not is further determined. The preset WiFi hotspots may include WiFi hotspots that are in an indoor environment. The preset WiFi hotspot can be set by a user in advance and stored in the mobile terminal; the mobile terminal can also obtain the information from other sources such as a server and the like; the mobile terminal can also count or learn historical habit data of the WiFi function used by the user, and then the preset WiFi hotspot is determined.
Further, the method can also comprise the following steps: acquiring WiFi hotspot connection history in the mobile terminal; and determining a preset WiFi hotspot according to the WiFi hotspot connection history. Wherein the WiFi hotspot connection history comprises: the mobile terminal comprises at least one of time for establishing connection with the WiFi hotspot, duration for establishing connection with the WiFi hotspot in a connection state, times for establishing connection with the WiFi hotspot, a verification mode when establishing connection with the WiFi hotspot, and operation executed by the mobile terminal when establishing connection with the WiFi hotspot in a connection state.
The determining of the preset WiFi hotspot according to the WiFi hotspot connection history comprises at least one of the following steps:
when the mobile terminal is determined to be connected with a first WiFi hotspot within a preset time period of a first preset statistical cycle according to the WiFi hotspot connection history, determining the first WiFi hotspot as a preset WiFi hotspot; when the fact that the duration of the mobile terminal in a connection state with a second WiFi hotspot in a second preset statistical period reaches a preset duration threshold value is determined according to the WiFi hotspot connection history, determining the second WiFi hotspot as a preset WiFi hotspot; when the number of times of establishing connection between the mobile terminal and a third WiFi hotspot in a third preset statistical period reaches a preset number threshold value is determined according to the WiFi hotspot connection history, determining the third WiFi hotspot as a preset WiFi hotspot; when the verification mode that the mobile terminal is automatically connected when the mobile terminal is recently connected with a fourth WiFi hotspot is determined according to the WiFi hotspot connection history, determining the fourth WiFi hotspot as a preset WiFi hotspot; and when the mobile terminal is determined to be in a connection state with a fifth WiFi hotspot according to the WiFi hotspot connection history, executing an operation with a security level higher than a preset operation security level, and determining the fifth WiFi hotspot as a preset WiFi hotspot. The advantage of this arrangement is that the preset WiFi hotspot is automatically set. It can be understood that, in the above 5 items, the preset WiFi hotspot is automatically set by the mobile terminal, and on the basis of any one or more items, the result automatically set by the mobile terminal may be modified by the user. For example, a preset WiFi hotspot list is added in the mobile terminal, the preset WiFi hotspots contained in the preset WiFi hotspot list are automatically set by the mobile terminal, the preset WiFi hotspot list can be displayed on a screen for a user to look up and edit, and the user can perform operations such as adding, deleting and modifying the preset WiFi hotspots in the preset WiFi hotspot list. The advantage of this arrangement is that the preset WiFi hotspot can be more accurately used to identify whether the mobile terminal is in an indoor environment.
The above provides some ways of determining whether the usage scenario information meets the preset power consumption reduction condition, and based on the number of searched satellites or the satellite signal strength, the comparison result based on the weather information, and whether the WiFi hotspot information list searched includes the preset WiFi hotspot corresponding to the indoor environment, it can be understood that these several determination ways may be used in combination, or any one or more of them may be selected according to the actual situation, so as to improve the determination efficiency or the determination accuracy. In addition, other determination methods are also possible, and the embodiments of the present application are not limited.
In some embodiments, when it is determined that the usage scenario information satisfies a preset power consumption reduction condition, controlling the GNSS module to close a preset number of channels of the correlators includes: determining a preset number when the use scene information is judged to meet a preset power consumption reduction condition; sending a correlator channel closing instruction to the GNSS module to instruct the GNSS module to close a preset number of channels of the correlator, wherein the preset number is included in the correlator channel closing instruction. The advantage of this arrangement is that the mobile terminal can determine the number of correlator channels that need to be closed according to actual conditions, and more reasonably control the operating state of the correlator in the GNSS module. The factors that can be considered in the actual situation are not limited in this application, and may include, for example, the number of searched satellites, specific values of satellite signal strengths, and the like.
The method has the advantages that the number of correlator channels needing to be closed can be determined more reasonably, and the working state of correlators in the GNSS module can be controlled reasonably, so that the power consumption of the GNSS module can be reduced.
In addition, the motion state results can be directly read from other built-in units of the mobile terminal, in order to assist the Positioning work of the GNSS module, a Positioning chip supplier (such as a high pass) configures an auxiliary Positioning module for the GNSS module, such as a Sensor Assisted Positioning (SAP) module, after the GNSS module is started up, the SAP module is also started up together, a behavior recognition (activerecognition) unit in the SAP module continuously recognizes what behavior state the user is in, for example, may include a VEHIC L E (driving), a cyc L (bicycle or bicycle), an Application Recognition (AR), a RUNNING recognition result, a RUNNING data acquisition and a RUNNING data acquisition result acquisition process calculation process, a resource acquisition process calculation process, a process.
The corresponding relation between different motion states and the preset number can be stored in the mobile terminal in advance, and for a mobile terminal with fixed configuration, the total number of channels of the correlator in the GNSS module is fixed, so that the preset number of the channels which need to be closed and correspond to different motion states can be determined according to modes such as experiments or simulation.
Illustratively, the total number of channels is 12, and a corresponding relationship between the motion state and the preset number is given in table 1 below.
