Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, a schematic diagram of the system layer based positioning of the present application is shown.

In the embodiment of the application, the positioning method can be applied to terminal equipment with a positioning function, the terminal equipment has at least one function of data storage, processing and the like, and the terminal equipment can comprise a mobile terminal, an intelligent wearable device and the like. The terminal equipment is provided with a positioning sensor, the positioning sensor is a sensor with a positioning function, and the positioning sensor comprises at least one of the following components: a Global Navigation Satellite System (GNSS) module, an inertial sensor, a magnetic sensor, a barometer, WiFi, bluetooth, and other positioning sensors. The GNSS generally refers to all satellite navigation systems including global, regional, and enhanced satellite navigation systems, such as the GPS in the united states, the Glonass (Glonass) in russia, the Galileo (Galileo) in europe, the beidou satellite navigation system in china, and based on the difference of the selected satellite positioning, a GPS module, a Glonass module, a beidou module, and the like may be provided in the terminal device. The inertial sensor is used to measure velocity information such as linear velocity, angular velocity, etc., and thus the inertial sensor may include an accelerometer, which is a meter for measuring acceleration, a gyroscope, which is an angular motion detection device, such as measuring angular velocity, etc. Magnetic sensors are used to measure magnetic fields and other parameters, such as measuring geomagnetism.

In the embodiment of the present application, the terminal device generally adopts a positioning module for positioning, for example, a GNSS module is adopted for positioning, a magnetic sensor is adopted for positioning, and the like, and in the positioning process, continuous positioning is required to obtain accurate positioning data, for example, the positioning frequency is 1 time/s. Correspondingly, continuous positioning by adopting the positioning module also causes the problem of larger power consumption, so that in order to reduce the power consumption in the positioning process, the embodiment of the application can estimate the power information of the terminal device, such as estimating the power information after a certain time, and estimating the power information used in a certain time, wherein corresponding set time can be set, so as to estimate the power information of the terminal device after the set time, or the power information used by the terminal device during the set time. For example, the set time may be a time period, the set time from the current time to the next time is the time to be estimated, if the current time is 14 o' clock, and the set time is half an hour, the power information of the device at 14:30 time is estimated, and the estimated power information may be estimated remaining power, estimated used power, and the like. And judging whether the continuous positioning of the positioning module can be supported or not and whether the continuous positioning can influence the subsequent use of the user or not based on the estimated electric quantity information. The subsequent positioning operation is determined according to the condition satisfied by the power information, and one or more conditions for determining the performed positioning operation may be set, so that different conditions may correspond to different positioning operations, and different positioning operations may consume different power, and thus, in one example, different levels of conditions may be set, so that different levels of positioning operations may be performed based on the estimated power information to reduce power consumption.

The embodiment of the application can be applied to various scenes, the electric quantity information of the terminal is estimated in various scenes, the positioning frequency of the positioning module is reduced according to the condition met by the electric quantity information, and the map data is called to assist positioning. For example, the power information of the terminal device is predicted and whether the condition is met is judged in the positioning process, and the positioning can be executed before, after or during the positioning process; for another example, when the software with the positioning authority is started, the power information of the terminal device is predicted and whether the condition is met is judged, that is, the power information is predicted and judged by taking the execution of the positioning related function as a trigger point. And the electric quantity information can be periodically predicted and condition judgment can be performed in the operation process of the terminal equipment.

The positioning frequency of the positioning module can be reduced based on the condition that the estimated electric quantity information meets, namely the positioning module is not adopted for continuous positioning, for example, the positioning module is positioned once every second and is reduced to be positioned once every 10 seconds, or the positioning module is reduced to be started to be positioned according to requirements, and the like, so that the electric quantity consumed by using the positioning module is reduced. Meanwhile, in order not to affect the normal positioning of the equipment, a map module can be arranged on the bottom layer of the equipment, map data is adopted for assisting positioning, for example, the position of a user is judged based on the speed data and the map corresponding to the equipment, and then the corresponding positioning data is determined based on the position, so that the normal positioning can be ensured.

Therefore, after the estimated electric quantity meets the condition, the positioning frequency of the positioning module can be reduced, and meanwhile, the map data is adopted to assist positioning and obtain the positioning data, so that the power consumption of the positioning module for positioning can be reduced, and the normal positioning is not influenced.

In this embodiment, in order to reduce the amount of power consumed by the positioning module in the terminal in the positioning, the above-mentioned operation in the positioning power saving mode may be performed, so that the system layer corresponding to the operating system of the terminal may be improved, a map module is added in the system layer, that is, a map matching technique is implanted into the system layer, the map module may assist the positioning module in positioning, the use of the positioning module is reduced to reduce the consumption of power to the terminal due to positioning, and a positioning policy control module is provided in the system layer, and the positioning policy control module determines a setting condition that the estimated amount of power satisfies based on the positioning policy control module, and performs a corresponding operation in the positioning power saving mode according to the setting condition. The system layer of the terminal comprises: the positioning module 10, the map module 20, the positioning sensor 30 and the positioning strategy control module 40, the map module 20 can assist positioning based on map data, the map data can be stored in a memory of the terminal, and the map data can also be obtained from a network. The positioning sensor 30 may comprise a positioning module, such as a GNSS module. The positioning of the terminal device can be assisted by the server 40, such as transmitting map data, collecting the positioning data of the user for analysis, etc.

In the embodiment of the present application, the map data used by the map module may include road map data, that is, the map data includes road information, such as a city map. Therefore, the city where the user is frequently located can be determined in advance, the road map data of the city is cached in the map module and is convenient to use when needed, and the corresponding road map data can be acquired from the network and cached in the map module when needed.

In the embodiment of the application, various power-saving positioning operations can be executed. Wherein, the reducing the positioning frequency of the positioning module comprises at least one of the following: reducing the positioning frequency of the positioning module to a set value; and calling a positioning module to position after the trigger point is met. That is, the positioning frequency of the continuous positioning by the positioning module may be reduced to a set value, or a higher value of the positioning frequency may be reduced to a set value, for example, 1 time/second is adjusted to 0.1 time/second, that is, 1 time is positioned every 10 seconds. In another example, the positioning module may be further activated to perform positioning according to a requirement, and therefore, some trigger points such as a road intersection, a road turning intersection, and the like may be set, so that the positioning module is invoked to perform positioning after the trigger points are reached, for example, the positioning module may be invoked to perform positioning when it is determined that the vehicle approaches the road intersection according to map data. The road intersection refers to a position where a road is branched, such as an intersection and a T-shaped intersection, the road turning intersection refers to an intersection where the road turns, such as a left turn and a right turn, and the approach refers to a distance from the road intersection to a set range, such as within 10 meters.

In an optional embodiment, the invoking map data to assist positioning includes: when the positioning module does not execute the positioning operation, acquiring moving distance information; matching the moving distance information with map data to determine corresponding position data; and determining corresponding positioning data according to the position data. When the positioning module does not perform positioning operation, in order to determine positioning data, the moving distance information corresponding to the terminal can be determined, for example, the running speed is determined through other positioning sensors, some road models and the like, the moving distance information can be determined based on time, then the moving distance information is matched with map data, wherein the position data of the terminal on the map can be determined based on the last output positioning data, then the updated position data after the moving distance information is moved on the map can be determined, and the positioning data can be determined based on the updated position data corresponding to the longitude and latitude information. Therefore, in an optional embodiment of the present application, for the positioning data obtained from each positioning, the positioning data may be further matched with the map data to determine the position data on the map, so as to assist the next positioning.

The road model in the embodiment of the present application refers to a data set for road matching, and information such as a moving speed and a moving distance of a user can be matched based on the road model, for example, the road model includes a road speed model, and the road speed model refers to a speed model when the user travels on a road in a unit time period established according to a large amount of user history data, so that the moving speed of the user can be estimated based on the road speed model, and the information of the moving distance of the user can be determined.

Wherein the step of acquiring the moving distance information includes at least one of: calling an inertial sensor to obtain speed information, and determining moving distance information of unit time according to the speed information; determining a corresponding road and the driving speed of the road according to the map data; and determining moving distance information per unit time according to the running speed. For the movement distance information: one example can be determined by the inertial sensor, that is, the inertial sensor is called to obtain speed information, where the speed information may include a linear speed and an angular speed, so as to determine a moving speed and a direction of the terminal, for example, the linear moving speed is determined by the linear speed, and data such as a steering direction of the terminal is determined by the angular speed, so as to determine moving distance information of a unit time based on the speed information, where the unit time is determined according to a frequency or a positioning period of the inertial sensor, so as to obtain the moving distance information of the terminal in the current positioning process; another example may be determined by the travel speed of a road, i.e. the road on which the terminal is located is matched based on the last positioning data and map data, then the travel speed of the road in the time period is determined based on a road speed model, and then the moving distance information per unit time, which may be determined according to the positioning period, e.g. 1 second, is determined according to the travel speed. The road speed model is used for determining the speed of a specified road in a specified time period, wherein the running speed of each road in each time period can be estimated through positioning data provided by a large number of users, so that the running speed model, for example, between 7:00 and 7:30, Nanjing road, with an interval of 50 meters and an average running speed in each 50 meters is determined.

The embodiment of the application can combine the positioning frequency of the positioning module and various modes of calling map data for assisting positioning. Therefore, for one example, the positioning frequency of the positioning module can be reduced to a set value, and when the positioning module does not perform the positioning operation, the inertial sensor is called to determine the moving distance information, and the moving distance information is matched with the map data to determine the positioning data; for another example, the positioning frequency of the positioning module may be reduced to a set value, and when the positioning module does not perform the positioning operation, the moving distance information is determined according to the driving speed of the corresponding road determined by the map data, and the moving distance information is matched with the map data to determine the positioning data; for another example, the positioning module may be invoked for positioning after the trigger point is met, and when the positioning module does not perform the positioning operation, the inertial sensor may be invoked for determining the movement distance information, and the movement distance information and the map data may be matched for determining the positioning data; for another example, the positioning module may be invoked for positioning after the trigger point is met, and when the positioning module does not perform a positioning operation, the moving distance information may be determined according to the driving speed of the corresponding road determined by the map data, and the moving distance information may be matched with the map data to determine the positioning data. Thereby reducing the consumption of power through a combination of various means.

The combination of the different modes also has difference on the consumption of the electric quantity, for example, based on the difference between the set value and the requirement, the two modes of calling as required by the positioning module and reducing the positioning frequency to the set value have different consumption of the electric quantity. Therefore, the embodiment of the application can divide the grades or ranges based on the remaining power, so as to meet different setting conditions, and different setting conditions can correspond to different power saving modes, for example, three-level power saving modes are set: the first level is a general power-saving mode, and a mode of reducing the positioning frequency to a set value and calling an inertial sensor is adopted; the second level is a deep power-saving mode, and a mode of calling a positioning module and calling an inertial sensor by meeting the requirement of a trigger point is adopted; the third level is an extreme power saving mode, and a mode of calling a positioning module and determining the corresponding running speed of a road by meeting a trigger point is adopted. Of course, it is also possible to set power saving modes such as secondary, quaternary, etc., or determine the specific manner to be adopted based on more power saving status operation levels.

In the embodiment of the application, in order to save the electric quantity of the terminal, the screen brightness of the terminal can be reduced when the positioning module does not execute the positioning operation; and when the positioning module executes the positioning operation, the screen brightness of the terminal is increased. Thereby reducing power consumption by adjusting the brightness of the screen.

Referring to fig. 2, a flowchart illustrating steps of an embodiment of a positioning method of the present application is shown.

And step 202, predicting the electric quantity information of the terminal equipment.

And 204, reducing the positioning frequency of the positioning module according to the condition met by the electric quantity information, and calling map data to assist positioning.

When the positioning module in the system layer performs positioning, the positioning module in the positioning sensor may be called to obtain positioning data, such as a satellite positioning signal of a GPS, and the positioning data is determined based on the positioning signal. Since the power consumption is relatively large by using the positioning module for continuous positioning, the power information of the set time, such as the estimated remaining power, the estimated power consumption, etc. of the terminal at the corresponding time based on the set time can be predicted. It is determined whether a condition is satisfied based on the estimated power amount information. If the condition is not met, the electric quantity of the terminal equipment is sufficient after the set time, and the positioning module can be used for continuously positioning to output positioning data. If the estimated electric quantity information meets the condition, the positioning frequency of the positioning module can be reduced based on the condition, so that the positioning module is not adopted for continuous positioning, but is positioned at intervals or according to requirements, and in order to ensure the normal positioning of the terminal, map data can be called for auxiliary positioning, for example, the position is determined based on data such as speed, distance and the like and the map data, the positioning data is determined based on the position and output to the application of an application layer, so that the positioning function is provided for the application, and for example, the positioning function is output to a navigation application for navigation.

In conclusion, the electric quantity information of the terminal equipment is predicted, the positioning frequency of the positioning module is reduced according to the condition met by the estimated electric quantity information, so that the consumption of the electric quantity is reduced, the map data is called for assisting positioning, the terminal can normally position, the corresponding positioning data is output, the consumption of the electric quantity is reduced, and the normal positioning of the terminal is not influenced.

In an embodiment of the present application, taking setting of a three-level power saving mode and estimation of remaining power as an example, corresponding conditions may be set to include: a first condition, a second condition, and a third condition. Wherein, if the estimated remaining capacity is within a first range, it is determined that a first condition is satisfied; determining that a second condition is satisfied if the estimated remaining power is within a second range; and if the estimated remaining capacity is within a third range, determining that a third condition is met.

Referring to fig. 3, a flowchart of terminal side steps of another embodiment of the positioning method of the present application is shown.

And step 302, predicting the electric quantity information of the terminal equipment according to the terminal electric quantity information and the battery use habit information.

When the positioning module in the system layer performs positioning, the positioning module in the positioning sensor may be called to obtain positioning data, such as a satellite positioning signal of a GPS, and the positioning data is determined based on the positioning signal. Because the power consumption is relatively large when the positioning module is used for continuously positioning, the power information of the terminal equipment can be predicted, and the method comprises the following steps: the power information of the terminal device after the set time, or the power information used by the terminal device during the set time. According to the embodiment of the application, the electric quantity information of the terminal equipment can be predicted according to the electric quantity information of the terminal and the battery use habit information. The battery use habit information can be preset, and is determined according to the use habit of the user on the battery, and can be used for determining the electric quantity use condition of the user in a certain time, so that each user can correspond to personalized battery use habit information, and certainly, universal battery use habit information can also be adopted for the condition that a new user and the like do not have the battery use habit information.

The battery use habit information includes: the remaining capacity and time may be a corresponding relationship, such as a curve of the remaining capacity and time, so that the remaining capacity corresponding to the specified time may be determined based on the corresponding relationship. The terminal electric quantity information is electric quantity information acquired from the terminal equipment, and the terminal electric quantity information comprises: the current time and the terminal residual capacity of the current time. Therefore, the residual capacity can be estimated based on the corresponding relation, the current time, the residual capacity of the corresponding terminal and other information.

The method for predicting the estimated residual capacity of the set time according to the terminal capacity information and the battery use habit information comprises the following substeps:

sub-step 3022, querying a corresponding relationship between the remaining capacity and the time according to the current time, and determining the remaining capacity in the corresponding relationship.

The corresponding relation between the remaining power and the time can be inquired, and the remaining power of the current time in the corresponding relation is determined, namely the remaining power which is usually used by the user at the current time.

And a substep 3024 of determining whether the remaining power of the terminal matches the remaining power in the correspondence. If yes, namely the terminal residual capacity is matched with the residual capacity in the corresponding relation, executing a substep 3026; if not, that is, if the remaining power of the terminal does not match the remaining power in the corresponding relationship, performing substep 3028. When determining whether the remaining power is matched, the same is determined as matching, and a certain range can be set, wherein the matching is performed within the range, if the power is expressed by percentage, the matching range is [ -5%, + 5% ], that is, the terminal remaining power is matched within plus or minus 5% of the inquired remaining power.

And a substep 3026, determining the remaining power after the set time according to the corresponding relationship, and using the remaining power as the power information of the terminal device after the set time.

After the residual capacity of the terminal is judged to be matched with the residual capacity in the corresponding relation, the corresponding relation between the residual capacity and the time can be inquired, the residual capacity after the set time is reached is determined, and the inquired residual capacity is determined as the electric capacity information of the terminal equipment after the set time.

For example, if the current time is 11 points, the remaining capacity of the terminal is 70%, the remaining capacity of 11 points in the corresponding relationship is 73%, and the matching range is [ -5%, + 5% ], it is determined that the remaining capacity of the terminal matches the remaining capacity in the corresponding relationship. If the set time is 40 minutes, the time required to be queried is 11:40, the remaining power of 11:40 in the corresponding relation is determined to be 50%, the power information of the terminal device after the set time, namely the estimated remaining power, is 50%, or the range of the power information is determined based on errors, such as [ 45%, + 55% ], and the like.

And a substep 3028, determining the remaining power after the setting time according to the corresponding relationship, and determining the power information of the terminal device after the setting time according to the remaining power after the setting time and the terminal remaining power.

If the terminal residual capacity is not matched with the residual capacity in the corresponding relation, the residual capacity can be estimated based on the use habit of the user to the battery, namely, the residual capacity can be inquired in the corresponding relation between the residual capacity and the time, the residual capacity after the set time is reached is determined, the electric quantity consumption difference consumed in the set time in the corresponding relation is determined, and then the electric quantity information of the terminal equipment after the set time is determined based on the terminal residual capacity and the electric quantity consumption difference.

For example, the current time is 11 points, the terminal residual capacity is 70%, the matching range is [ -5%, + 5% ], and the set time is 40 minutes. The residual capacity at 11 points in the corresponding relation is 60%, and the residual capacity of the terminal and the residual capacity in the corresponding relation can be determined to be not matched. The query time is 11:40, the remaining power of 11:40 in the corresponding relationship is determined to be 30%, and the power consumption difference value in 40 minutes is determined to be 60% -30% — 30%, so that the power information of the terminal device after the set time is estimated to be 70% -30% — 40%, or [ 35%, + 45% ], and the like.

The steps can predict the information of the electric quantity used by the terminal based on the information of the electric quantity of the terminal and the information of the battery use habit. For example, the battery use habit information includes: using the corresponding relation between the electric quantity and the time. For example, the battery usage habit information may be queried according to the current time, so as to determine the power information used in the preset time as the power information used by the terminal device during the set time. And for example, the power information used by the terminal device during the set time period is predicted according to the application running in the terminal device and the residual power of the terminal device, and by combining some habits and other information.

The corresponding threshold may be determined based on the range of the power information, for example, the first range is [ a first threshold, a second threshold ], the second range is [ a second threshold, a third threshold ], the third range is [ a third threshold, 0 ]), and the like.

Step 304, determining whether the power information is greater than a first threshold.

If yes, i.e. the power information is greater than the first threshold, go to step 324; if not, that is, the power information is not greater than the first threshold, go to step 308.

Step 306, determining whether the electric quantity information is greater than a second threshold value.

If the power information is greater than the second threshold, that is, the power information is within the first range, it is determined that the power information satisfies the first condition, and step 308 is executed; if not, that is, the power information is not greater than the second threshold, go to step 312.

Step 308, reducing the positioning frequency of the positioning module to a set value, and executing a positioning operation when the positioning period is reached according to the set value.

If the electric quantity information meets the first condition, the positioning frequency of the positioning module can be reduced to a set value, and the positioning period of the positioning module can be determined based on the positioning frequency, so that the positioning module is adopted to execute positioning operation when the period time is up, and positioning is performed according to the step 310 when the positioning period is not up.

Step 310, when the positioning module does not execute the positioning operation, calling an inertial sensor to determine speed information; and determining moving distance information according to the speed information, and determining corresponding positioning data by using the moving distance information and the map data.

The method comprises the steps that electric quantity information meets a first condition, when a positioning period is not reached, positioning is carried out through an inertial sensor and map data, therefore, when the positioning module does not execute positioning operation, the inertial sensor is called to determine speed information, then moving distance information is determined according to the speed information, unit time can be determined according to the period for calling the inertial sensor, then moving distance information of a terminal in the unit time is determined, position data of the terminal moving on the map data are determined based on the position of previous positioning data on the map data and the moving distance information in the unit time, then longitude and latitude information corresponding to the position data are determined, and the longitude and latitude information is used as positioning data.

In step 312, it is determined whether the power information is greater than a third threshold.

If yes, that is, the electric quantity information is greater than the third threshold, it is determined that the electric quantity information is within the second range and meets the second condition, and step 314 is executed; if not, that is, the electric quantity information is not greater than the third threshold, it is determined that the electric quantity information is within the third range and meets the third condition, and step 320 is executed.

Step 314, determining corresponding road information according to the map data, and determining whether the trigger point is reached according to the road information.

And determining that the electric quantity information is in a second range, meeting a second condition, matching positioning data obtained by positioning with map data, determining corresponding road information, namely determining the position of a road on the map, and then judging whether a trigger point is reached, namely whether the trigger point is in the range of a road bifurcation. If yes, go to step 316; if not, go to step 318.

Step 316, the positioning module is invoked to perform the positioning operation.

If the trigger point is reached, the positioning module is called to execute positioning operation, and the positioning module can execute positioning to acquire corresponding positioning data.

Step 318, calling an inertial sensor to determine speed information; and determining moving distance information according to the speed information, and determining corresponding positioning data by using the moving distance information and the map data.

If the trigger point is not reached, determining speed information such as linear speed, angular speed and the like according to the tunable inertial sensor so as to determine information such as the moving speed, direction and the like of the terminal, then determining moving distance information of unit time according to the speed information, matching a position corresponding to updating on map data according to the moving distance information and a position determined on the map data before, and then determining corresponding positioning data based on longitude and latitude information of the position.

And 320, determining corresponding road information according to the map data, and determining whether the trigger point is reached according to the road information.

And determining that the electric quantity information is in a third range, meeting a third condition, matching positioning data obtained by positioning with map data, determining corresponding road information, namely determining the position of a road on the map, and then judging whether a trigger point is reached, namely whether the trigger point is in the range of a road bifurcation. If yes, go to step 316; if not, go to step 322.

Step 322, determining a driving speed corresponding to the road information; and determining moving distance information according to the driving speed, and determining corresponding positioning data according to the moving distance information and the map data.

If the current time does not reach the trigger point, determining the driving speed of the road section where the current time is located according to the road information, then determining the moving distance information of unit time based on the driving speed, matching the position updated on the map data correspondingly according to the moving distance information and the position determined on the map data, and then determining the corresponding positioning data based on the longitude and latitude information of the position.

At step 324, a positioning module is used to perform a continuous positioning operation.

The electric quantity information is larger than the first threshold value, the electric quantity of the battery is higher after the set time is determined, and the power-saving positioning operation is not needed, so that the positioning module can be continuously adopted for continuous positioning.

Step 326, outputting the positioning data.

In the embodiment of the application, if the positioning module does not execute the positioning operation, the screen brightness of the terminal is reduced; and when the positioning module executes the positioning operation, the screen brightness of the terminal is increased. If the positioning module does not perform the positioning operation, such as

steps

310, 318, 324, etc., the screen brightness of the terminal is reduced, thereby reducing the consumption of power; accordingly, when the positioning module performs the positioning operation in

steps

308, 316, and 322, the screen brightness of the terminal is increased, so that the application in the application layer can display the positioning result based on the positioning data.

In the embodiment of the present application, after the setting condition that the electric quantity information satisfies is determined, a corresponding power-saving positioning operation may be provided, for example, the positioning frequency of the positioning module is reduced and the map data is called to assist positioning, but sometimes a user may have a higher requirement for positioning accuracy, or the user is in a state of being able to be charged at any time, and there is no need to worry about the problem of power consumption, that is, some users may prefer to perform positioning through the positioning module. Therefore, before performing the power-saving positioning operation, the user may be asked whether the power-saving positioning operation needs to be performed, for example, after determining that the first condition, the second condition, or the third condition is satisfied by the power information, a prompt message may be displayed before performing the

above steps

308, 310, 316, 318, 322, and 324, so as to provide the user with the power-saving positioning operation, or a prompt that the power-saving positioning operation may affect the positioning accuracy, have a certain error, and the like may be prompted, so as to determine the performed operation based on the instruction information of the user. If the user confirms that the power-saving positioning operation can be executed, the steps of reducing the positioning frequency of the positioning module and calling the map data to assist positioning are executed, and if the user confirms that the power-saving positioning operation cannot be executed, the positioning module is continuously adopted for continuous positioning.

In the above embodiment, when the positioning module does not perform positioning operation, the moving distance information is determined by the inertial sensor, the corresponding speed of the road, and the like, and positioning is performed with the assistance of map data, and a certain error may exist in the positioning process, so that after positioning operation is performed by the positioning module to obtain positioning data, the positioning module can match the map data based on the positioning data, adjust the positioning position, and provide positioning accuracy when the subsequent positioning module does not perform positioning.

In an optional embodiment of the present application, the terminal receives map data corresponding to an active area in a period, and updates the stored map data by using the map data corresponding to the active area. The active area is an area frequently acquired by the terminal in the update period, and may be an administrative area, such as province, city, county, district, etc., and may also be determined according to the corresponding operation route of the terminal, which is not limited in this embodiment. The map data stored in the terminal can be updated regularly, and the map data actively requested or fed back by the server can be updated after the update period is reached. The map data of the resident area is usually stored locally, if a user works and lives in the state, a map of the state city is stored, but the area where the user is located may be changed due to various reasons such as business trip, work change, travel and the like, so that information of the area where the terminal is located can be counted in a period, an activity area of the user in the period is analyzed, then when the map data needs to be updated, the server obtains and feeds back the map data corresponding to the activity area, the terminal receives the map data corresponding to the activity area, and the stored map data can be updated by using the map data corresponding to the activity area, for example, the map data of a newly added area can be stored and retained, and the map data stored before can be replaced by the map data.

The terminal does not store map data locally, can request positioning related information from the server to assist positioning, and can send a data request to the server to acquire the required map data. The server can match position data corresponding to the positioning information on map data; and taking the position data as a reference point, acquiring map data of an area corresponding to a preset distance, and feeding back the map data of the area to the terminal equipment. When the map data is returned to the terminal, the map data of a partial area corresponding to the positioning information can be acquired by considering the factors such as the network condition, the data size, the processing efficiency and the like, so that the position data corresponding to the positioning information, namely the positioning position, can be matched on the map data, then the feedback area is determined by taking the positioning position as a reference, the specific area to the lead can be determined according to the network condition, the terminal condition, the speed and the like, and after the area is determined, the map data corresponding to the area is acquired.

In the embodiment of the application, in the process of positioning the terminal equipment such as a mobile phone and a tablet personal computer, the output from the sensor hub or the behavior recognition module can be received to judge whether the terminal is in a driving mode (namely, a driving state), so that assistance is performed on speed, map data matching and the like in the positioning process, and invalid data is filtered.

Referring to fig. 4, a schematic diagram of another system layer based positioning of the present application is shown.

The system layer of the terminal comprises: a positioning module 10, a map module 20, a positioning sensor 30, a positioning strategy control module 40, a road speed matching module 50, a battery management module 60, a battery control unit 70, a screen control unit 80 and an application 90.

The road speed matching module 50 may determine a driving speed corresponding to the terminal based on a driving speed model generated by the server; the battery management module 60 is used for managing the battery; the battery control unit 70 is used for acquiring data such as the electric quantity of the battery; the screen control unit 80 is used to control the screen; the application 90 is an application in the application layer that requires positioning data, such as a navigation application, a mapping application, a communication application, and the like. The positioning sensor 30 includes various positioning sensors such as a GNSS module and an inertial sensor. For example, the GNSS module provides continuous positioning information required by the positioning module 10.

The whole system framework is as shown in fig. 1, the underlying data acquisition units include a positioning sensor 30, a battery control unit 70, and a screen control unit 80, and the positioning policy control module 40 can perform data acquisition and information interaction with these data acquisition units. The positioning policy control module 40 may further perform command interaction with the positioning-related application 90, so as to prompt the user, for example, to prompt that this may cause a certain risk of accuracy loss, and perform the determination of the positioning policy based on the instruction of the user before entering the power-saving positioning mode and performing the power-saving positioning operation. The positioning policy control module 40 may also input the sensor data acquired from the data acquisition unit to the positioning module for positioning, and also receive a control command from the positioning module to adjust the operation mode of the positioning sensor.

The positioning module 10 may integrate various positioning related information to determine the positioning data, such as interaction with a map module and a road speed matching module, obtain corresponding map data and driving speed, and obtain sensor data of a GNSS module and an inertial sensor from the positioning policy control module 40, so as to calculate the positioning data of the terminal. The positioning module 10 can also calculate different data to position by receiving different commands from the positioning strategy control module, and the positioning module 10 also performs information interaction with the server and reports positioning information to the server, so that on one hand, basic data are provided for perfecting a road speed model, and on the other hand, data support is provided for depicting an activity area of a user within a period of time.

The battery management module 60 may collect the information of the electric quantity at each time and report the information to the server, and always obtain the information of the battery usage habit corresponding to the user from the server, so as to facilitate the positioning policy control module 40 to determine the power saving policy.

In the embodiment of the application, the terminal equipment can collect one or more information in the electric quantity data corresponding to the positioning information and the time information and then report the information to the server. Therefore, the server can analyze various information such as users and roads based on the data, and can adjust corresponding user and road data along with the uploading of the data, so that the accuracy is improved. Namely, the server can use a large amount of data uploaded by the terminals to perform fitting and other processing, so that basic data are provided for perfecting a road speed model on one hand, and data support is provided for depicting an activity area of a user within a period of time on the other hand. The server can estimate the running speed model of each road in different time intervals through positioning information provided by a large number of users, wherein the positioning information can comprise longitude and latitude positioning data, corresponding speed information and the like, so that matching processing is carried out through a large number of positioning information and a map, information such as the speed of each road section is determined, and a corresponding running speed model is generated. When the GNSS module does not perform the positioning operation, the driving speed of the located position can be determined based on the driving speed model, and therefore, the driving speed model can be sent to the terminal to obtain the feedback driving speed based on the request of the terminal. The server can also judge the activity area of the terminal, namely the user, within a certain time through the positioning data to serve as the frequent area of the user, and then provides the map data corresponding to the acquired area for the user to download, and the activity area corresponds to the user and can determine the personalized activity area for the user. The server can also describe the corresponding relation between the battery residual capacity and the time of the user every day, such as a curve of the battery residual capacity and the time, through the electric quantity data corresponding to each time, so that personalized battery use habit information of the user is obtained and is used as a basis for presetting the residual capacity and adjusting a positioning strategy in the positioning process. The server may thus determine a corresponding travel speed model and build a user personal database that includes information about the user's activity area, battery usage habit information, etc. And in the process that the user uses the terminal, the data continuously go to the server, and the server correspondingly updates the driving speed model, the activity area and the battery use habit information.

Therefore, in the interaction process, the positioning module depends on the assistance of various modules, selects different positioning modes according to the command of the positioning strategy control module, and finally outputs the positioning modes to the positioning related application, so that the normal positioning of the terminal is not influenced while the power is saved. The interaction process is a data intercommunication process, so the system can learn and optimize continuously based on the interaction of data.

In this embodiment, in order to reduce the power consumption of the terminal in positioning, the above-mentioned operation of the power saving mode may be performed, so that the system layer corresponding to the operating system of the terminal may be improved, a map module is added in the system layer, that is, a map matching technique is embedded in the system layer, the map module may assist the positioning module in positioning, reduce the use of a GNSS module to reduce the power consumption of the terminal due to positioning, and a positioning policy control module is provided in the system layer, determine a setting condition that is satisfied by the power information based on the positioning policy control module, and perform a corresponding operation of power saving in positioning according to the setting condition.

In one example, the terminal is located using a GPS module. The first range corresponding to the first setting condition is assumed to be [ 80%, 50%), the second range corresponding to the second setting condition is assumed to be [ 50%, 20%), and the third range corresponding to the third setting condition is assumed to be [ 20%, 0%).

When the GPS module is in a continuous positioning state, the current residual electric quantity of the terminal and the battery use habit information of the user are firstly acquired, and the electric quantity information of the user after half an hour is estimated. If the electric quantity information is sufficient after half an hour, such as more than 80%, no adjustment of the positioning strategy can be made, and the GPS module is continuously used for continuous positioning. If the estimated half-hour after-battery information is not sufficient, e.g., less than 80% but greater than 50%, the user may be asked if the power-saving positioning mode needs to be enabled and informed that this may be without accuracy, enter the power-saving positioning mode if the user agrees, and otherwise continue to use continuous GPS positioning. If the estimated half-hour after power information is low, e.g., less than 50% but greater than 20%, the user may be asked if deep power save positioning mode needs to be enabled and informed that this may be loss of accuracy, need to be driven with caution, enter deep power save positioning mode if the user agrees, otherwise continue to use continuous GPS positioning. If the estimated electric quantity information after half an hour is extremely low, such as less than 20%, inquiring whether the user needs to enter the extreme power saving positioning mode or not, informing the user of risks and possible use inconvenience (such as screen brightness control and the like), if the user agrees, entering the extreme power saving positioning mode, otherwise, continuing to use the GPS positioning.

Under the power-saving positioning mode, the positioning frequency of the GPS module can be reduced, and the sensor data and the map data are combined to realize the cooperative positioning. The power consumption of the inertial sensor is much lower than that of the GPS module, so that after the power saving mode is entered, the GPS frequency can be reduced to 10s once, and the dead reckoning can be switched to within 9s without GPS positioning in the middle, wherein the dead reckoning means that the inertial sensor measures the motion state change (namely speed information) within each second, and the moving distance information can be calculated according to the last positioning data and speed information. However, the estimated moving distance information may cause a positioning error, and therefore, the position can be matched with the number of maps to obtain corresponding positioning data. When the next GPS module is adopted for positioning, the positioning data corresponding to the GPS module is output, the positioning data is adopted to correct the position on the map, and the position is taken as the initial position to carry out subsequent dead reckoning, so that the positioning continuity and accuracy are ensured, and the power consumption is reduced.

In the deep power-saving positioning mode, the GPS module can be called to position according to requirements instead of adopting fixed frequency positioning. In this example, it can be determined whether the terminal position is close to the intersection of the road, that is, whether the user corresponding to the terminal is about to perform one or more selections of the road, so as to ensure that the user does not miss the road at a critical place on the basis of saving power to the maximum extent, and as far as possible, no wrong guidance is caused. Therefore, when the intersection of the roads is not close, the motion state change (namely speed information) in each second is measured through dead reckoning, namely through the inertial sensor, the moving distance information can be calculated according to the last positioning data and speed information, and the position can be matched by combining the map number to obtain the corresponding positioning data. Until the crossing of approaching the road, when calling the GPS module and fix a position, the location data that the output GPS module corresponds to adopt this location data to correct the position on the map, and use this position to carry out subsequent dead reckoning as the initial, so both guaranteed location continuity and precision, reduced the consumption again. In this example, considering that the user has a low demand for screen display before reaching the road junction during navigation, the screen brightness may be reduced when the GPS module does not perform positioning, that is, before reaching the road junction, so as to achieve further power saving. Correspondingly, when the GPS module is called for positioning, the road bifurcation point is approached, and a user needs to select whether to change the road, so that the screen brightness can be improved again, and the user can conveniently check the road.

In the extreme power-saving positioning mode, further power is saved, the inertial sensor with high sampling frequency is abandoned for positioning, and a road speed model is adopted to provide speed data. Therefore, the GPS module can be called to position according to needs instead of adopting fixed frequency positioning. In this example, it can be determined whether the terminal position is close to the intersection of the road, that is, whether the user corresponding to the terminal is about to perform one or more selections of the road, so as to ensure that the user does not miss the road at a critical place on the basis of saving power to the maximum extent, and as far as possible, no wrong guidance is caused. Therefore, when the intersection of the roads is not close, the road information, namely the road section data, where the intersection is located is determined through the last positioning data and the map data, then the driving speed of the road section corresponding to the current time is determined by adopting the road speed model, the moving distance information can be calculated according to the last positioning data and the driving speed, and the positions can be matched by combining the map data to obtain the corresponding positioning data. Until the crossing of approaching the road, when calling the GPS module and fix a position, the location data that the output GPS module corresponds to adopt this location data to correct the position on the map, and use this position to carry out subsequent dead reckoning as the initial, so both guaranteed location continuity and precision, reduced the consumption again. In this example, considering that the user has a low demand for screen display before reaching the road junction during navigation, the screen brightness may be reduced when the GPS module does not perform positioning, that is, before reaching the road junction, so as to achieve further power saving. Correspondingly, when the GPS module is called for positioning, the road bifurcation point is approached, and a user needs to select whether to change the road, so that the screen brightness can be improved again, and the user can conveniently check the road.

According to the embodiment of the application, technologies such as map matching and road speed matching are implanted into a system layer, so that the basic positioning capacity of the mobile phone is fundamentally improved, and diversified power-saving data bases and strategies are provided. Therefore, various power-saving positioning operations are provided in the terminal, and the electric quantity requirement of a user in the positioning process is met.

The embodiment of the application provides various intelligent positioning strategies based on power consumption optimization, takes the problem that the power consumption of GNSS module positioning is compared into consideration, reduces the positioning frequency of the GNSS module, adopts other positioning methods with low power consumption as assistance, and simultaneously takes the requirement of a user on positioning precision into consideration, and provides corresponding positioning operation. The strategy provided by the embodiment of the application can also select power consumption optimization strategies of different degrees by integrating the residual capacity, so that various requirements of users are met.
