Description

Positioning method, device and equipment
Technical Field
This document relates to, but is not limited to, a positioning method, apparatus, device, and computer-readable storage medium.
Background
In positioning products, the requirements on power consumption are generally met, and the standard-reaching standby time is a qualified hard index of the products. Optimization with respect to power consumption of the product is particularly important.
Currently, the Positioning mode of the Positioning products is not only single GPS (Global Positioning System). And the positioning requirements of users under all scenes are met by combining three modes of base station positioning, WIFI (wireless fidelity) positioning and GPS positioning.
The GPS positioning depends on a GPS navigation satellite to realize positioning, belongs to a core positioning mode, and is accurate in positioning, but the GPS positioning depends on satellite signals and is greatly influenced by environmental factors, for example, the positioning fails because of satellite searching failure indoors.
The WIFI positioning is a process of scanning and collecting WIFI hotspot (AP) information through a WIFI hardware module, sending the collected information to a positioning server, and finally obtaining positioning information through calculation of the positioning server. The WIFI positioning relies on a positioning service provider, and generally under the indoor condition, more accurate position information can be obtained by scanning a plurality of WIFI hotspot information.
The base station positioning is a process of acquiring information of nearby base stations through a wireless modem module, sending the information of the base stations to a positioning server, and finally obtaining positioning information through calculation of the positioning server. The positioning error of the base station is large, and the base station can give an approximate position when WIFI positioning and GPS positioning are unavailable.
The three modes are integrated for positioning, namely, in the user positioning process each time, base station information is collected for base station positioning, AP information is scanned for WIFI positioning, and a GPS module is started for satellite searching for GPS positioning. In this positioning mode, when the user performs continuous positioning or performs repeated positioning at the same position, the power consumption is considerable, and the main consumption is GPS positioning. Therefore, research on methods for meeting the positioning requirements of users in various scenes and enabling the power consumption of products to reach the standard is urgent.

The base station positioning and WIFI positioning modes are that corresponding positioning information is collected, and finally the positioning information is sent to a positioning server at the cloud end for positioning. The three modes work together to meet the positioning requirements of users in various scenes.
In the positioning process, the embodiment of the invention identifies whether the positioning process is repeated (repeated and invalid positioning process or repeated positioning process at the same position and different time); if the positioning is repeated and invalid or the repeated positioning processing is carried out at the same position for different time, the GPS positioning is not started, and the effects of reducing the positioning power consumption and keeping the positioning accurate are achieved.

The identifying the current positioning process and determining whether the positioning process is repeated may include the following situations:
1. and comparing the current information with the historical positioning information, and determining whether the repeated positioning processing is performed according to a comparison result.
The historical positioning information may include base station information, WIFI hotspot information, positioning time and positioning results of the historical positioning records.
For example, a storage location for historical location data is established locally at the device. The storage unit stores the historical positioning data information record of the user. Each record contains four fields: the positioning system comprises base station information, WIFI hotspot information, positioning time and positioning results. Wherein the base station information includes CID: base station number, MCC: mobile country code, MNC: mobile network number, LAC: a location area code; the WIFI hotspot information comprises SSID: WIFI hotspot name, BSSID, and WIFI hotspot MAC address. This field may contain multiple pieces of WIFI hotspot information. The positioning time is time information when the positioning result is generated. The positioning result refers to the longitude and latitude values of the specific position obtained after the equipment reports the collected information of the base station, the WIFI and the GPS to the positioning server and the positioning server calculates.
The current information may be current time, a current WIFI hotspot information list, and current base station information.
(1) Determining whether to perform repeated positioning processing according to time information
The current information comprises current time, the historical positioning information comprises positioning time of historical positioning records, the current time and the positioning time of the latest historical positioning record are obtained, a difference value between the current time and the positioning time of the latest historical positioning record is determined, and when the difference value is smaller than a preset time threshold value, repeated positioning processing is determined.
In one embodiment, the current system time (set as Tc) and the time of the last historical positioning record (set as Th) are obtained, the difference between Tc and Th is calculated, and if the difference is less than the time threshold, repeated positioning is indicated.
(2) Determining whether repeated positioning processing is performed according to WIFI hotspot information
The current information comprises a current WIFI hotspot information list, the historical positioning information comprises historical positioning record WIFI hotspot information, the current WIFI hotspot information list is obtained, the current WIFI hotspot information list is matched with the historical positioning record WIFI hotspot information, the corresponding matching degree is determined, and when the matching degree is larger than or equal to a preset first matching degree threshold value, repeated positioning processing is determined.
In an embodiment, a WIFI hotspot information list (set as APlist) in the current environment is obtained. And matching the historical positioning data one by using the APlist, wherein the matched content is WIFI hotspot information comprising SSID and BSSID. And when each record is matched, calculating a corresponding matching degree (set as P), and if the matching degree P of the hot spot information in the APlist and the hot spot information in the history record reaches a higher percentage (a high threshold), determining that the repeated positioning processing is performed.
(3) Determining whether to perform repeated positioning processing according to base station information

If the TowerInfo is matched with the base station information in the record consistently, judging whether the matching degree P reaches a lower percentage (a low threshold value), and if the matching degree P reaches the lower percentage, determining that the positioning is repeated. This is because the TowerInfo can only assist in positioning, and the same base station information location may vary greatly. And when the WIFI matching degree reaches a high threshold value, directly sending positioning information. And when the WIFI matching degree only reaches a low threshold value, starting the base station for auxiliary positioning, and if the positions of the base stations are consistent, indicating that the position of the user does not change greatly.
2. And determining whether the positioning is repeated according to the moving distance.
And the moving distance is the moving distance from the last GPS positioning to the current time.
The moving distance can be calculated through an acceleration sensor, and when the moving distance is smaller than a preset distance threshold, the repeated positioning processing is determined.
When the positioning process is not started, Tracker starts to collect data of the acceleration sensor and calculates the moving distance of the device. In each fixed period (set to Ts), three-axis acceleration values (set to Axs, Ays and Azs) are collected once, average acceleration (set to Axv, Ayv and Azv) in the current collected total time period (set to Ta) is calculated, and the moving distance (set to St) of the current equipment is calculated according to the average acceleration.
When the positioning processing is started, the device moving distance St calculated according to the acceleration sensor at present is acquired, whether St is smaller than a distance threshold value or not is judged, and when the St is smaller than the distance threshold value, the repeated positioning processing is determined.
And step 302, when the current positioning processing is determined to be repeated positioning processing, not starting GPS positioning, and determining a positioning result according to historical positioning information.
And when the repeated positioning processing is judged according to the time information, taking the latest positioning result in the historical positioning information as the current positioning result.
And when the repeated positioning processing is judged according to the WIFI hotspot information, taking a positioning result corresponding to the WIFI hotspot information which is successfully matched in the historical positioning information as a current positioning result.
And when the base station information is judged to be repeatedly positioned, taking the positioning result corresponding to the successfully matched base station information in the historical positioning information as the current positioning result.
And when the repeated positioning processing is judged according to the moving distance, taking the latest positioning result in the historical positioning information as the current positioning result.
And after the positioning result is determined according to the historical positioning information, the positioning result is directly sent to a positioning server.
In one embodiment, when the current positioning processing is determined not to be the repeated positioning processing, the GPS positioning is started, and the positioning result is acquired and recorded.
The positioning server is used for acquiring positioning results, and recording the current base station information, the current WIFI hotspot information list, the positioning results and the current positioning time.
In one embodiment, the data information related to the calculated moving distance is reset and cleared, including the calculated St, Ta, and the like. And sending the data acquired by the current GPS module, the current base station information TowerInfo and the current WIFI hotspot information list APlist to a positioning server. And the positioning server performs positioning calculation according to the information and returns the positioning result to the equipment. And meanwhile, a new record is established in a storage unit of historical positioning data, and current base station information, WIFI hotspot information, a positioning result and current positioning time are stored in the record.
The embodiment of the invention can avoid repeatedly and ineffectively starting GPS positioning in the positioning process, thereby reducing the positioning power consumption of equipment, simultaneously ensuring the positioning accuracy and reducing the overhead of positioning calculation, thereby improving the standby time of the product and increasing the competitiveness.
The following describes an embodiment in detail.
In the embodiment of the invention, under the scene that the Tracker equipment adopts three modes of base station positioning, WIFI positioning and GPS positioning, historical positioning information and the characteristics of a G-Sensor (acceleration Sensor) in the equipment are mainly utilized, the historical positioning information is analyzed and compared, and the moving distance of the equipment is monitored by combining the G-Sensor, so that whether the equipment needs to start the GPS positioning or not is finally judged. Therefore, the repeated and invalid starting of GPS positioning in the positioning processing is avoided, the effect of reducing the positioning power consumption of the equipment is achieved, and meanwhile, the positioning accuracy is ensured and the overhead of positioning calculation is reduced.
Tracker first establishes a local storage unit of historical positioning data, and a user can preset the time limit or data size of data storage. The data in the local storage unit mainly comprises four key fields of base station information, WIFI hotspot information, positioning time and positioning results.
When a user carries out positioning, the base station information and the wifi hotspot information of the current position are matched in the historical data record, if the matching contact degree reaches a certain threshold value, GPS positioning is not started, and the positioning result in the historical record is directly sent to the server. If the moving distance is within a certain threshold value, GPS positioning is not started, and the positioning result in the latest history record is directly sent to the server. Otherwise, starting the GPS and carrying out new positioning.
And resetting the data of the moving distance of the G-Sensor monitoring equipment and starting a new monitoring action every time the user finishes one positioning. If the positioning is a new positioning, a new record is established in the local storage unit, and the corresponding positioning data is written into the record.
The functional modules divided in the implementation process of the present embodiment are shown in fig. 4, and include a historical positioning data storage unit 41, a positioning preprocessing unit 42 in the process of starting positioning, a positioning processing unit 43, a positioning record collection unit 44, and a moving distance calculation unit 45 in the process of not starting positioning.
The historical positioning data storage unit 41 is used to store historical positioning information of the user.
The location pre-processing unit 42 is used to identify duplicate invalid locations.
The location processing unit 43 is used to identify whether the current location of the user has been previously located.
The location record collection unit 44 is used for collecting historical location information of the user.
The movement distance calculation unit 45 is used to calculate the device movement distance.
The positioning processing unit 43 may comprise two parts, a first positioning processing subunit and a second positioning processing subunit. The first positioning processing subunit is used for identifying whether repeated positioning is carried out according to the WIFI hotspot information and the base station information, and the second positioning processing subunit is used for identifying whether repeated positioning is carried out according to the moving distance.
The following description is made for the implementation steps of each unit module:
1) historical positioning data storage unit 41
A location data storage unit is established locally at the device. Each data record in the storage unit mainly comprises four fields: the positioning system comprises base station information, WIFI hotspot information, positioning time and positioning results.
Wherein the base station information mainly comprises CID: base station number, MCC: mobile country code, MNC: mobile network number, LAC: location area code, signal: signal strength;
the WIFI hotspot information mainly comprises SSID: WIFI hotspot name, BSSID, and WIFI hotspot MAC address. This field may contain multiple pieces of WIFI hotspot information.
The positioning time refers to a time when the positioning result is generated.
The positioning result refers to the longitude and latitude values of the specific position obtained after the equipment reports the collected information of the base station, the WIFI and the GPS to the positioning server and the positioning server calculates.
2) When the positioning process is not started, the moving distance calculating unit 45 performs the steps as shown in fig. 5:
in step 501, Tracker collects triaxial acceleration values (Axs, Ays, and Azs) every other period Ts.
Step 502, Tracker calculates the total duration Ta of the current collected acceleration values, and calculates the sum of the accelerations collected in all periods.
In step 503, Tracker calculates the average acceleration values (Axv, Ayv, and Azv) over the duration of Ta.
And step 504, Tracker obtains the moving distance St in the Ta duration according to the average acceleration value.
Step 505 stores the calculated distance St.
3) When the positioning process is started, the positioning preprocessing unit 42 performs the steps shown in fig. 6:
step 601, obtaining the current positioning time Tc.
In step 602, the positioning time Th of the latest history is obtained.
Step 603, calculating the difference between the current positioning time Tc and Th.
Step 604, determining whether the difference between Tc and Th is within the time threshold, if the difference is smaller than the time threshold, step 605 is executed, otherwise step 606 is executed.
The time threshold is a preset value, and may be 5 seconds, for example.
And step 605, if the difference is smaller than the time threshold, the repeated positioning is indicated, the GPS positioning is not started, and the latest positioning result is directly sent to the server.
In step 606, if the difference is greater than or equal to the time threshold, the positioning processing unit 43 enters the first positioning processing subunit to perform the processing.
4) The execution steps of the first positioning processing subunit are shown in fig. 7:
step 701, acquiring a WIFI hotspot information list APlist and base station information TowerInfo in the current environment.
Step 702, matching items in the historical positioning data record by using APlist, wherein the matched content is WIFI hotspot information, including SSID and BSSID. When each record is matched, the corresponding matching degree P is calculated.
In step 703, it is determined whether the matching degree P is greater than or equal to a preset first matching degree threshold (reaching a higher percentage (high threshold)), if so, step 704 is executed, and if not, step 705 is executed.
Step 704, when the first matching degree threshold is reached, the GPS positioning is not needed to be started, and the positioning result of the history record is directly sent to the server.
Step 705, when the first matching degree threshold is not reached, using the TowerInfo to match the base station information in the record, wherein the matching content includes CID, MCC, MNC and LAC.
Step 706, determining whether the TowerInfo is consistent with the base station information in the record, if so, executing step 707, and if not, executing step 709.
In step 707, if the matching is consistent, it is determined whether the matching degree P is greater than or equal to the second matching degree threshold (reaches a lower percentage (low threshold)), if yes, step 708 is executed, and if not, step 709 is executed.
In step 708, the matching degree P reaches a low percentage, and the positioning result of the history record is directly sent to the server without starting GPS positioning.
And step 709, if the matching degree P does not reach a lower percentage or the topwerinfo is not matched with the base station information in the record, entering a second positioning processing subunit for processing.
5) The second positioning processing subunit performs the steps shown in fig. 8:
in step 801, the device movement distance St currently calculated from the acceleration sensor is acquired.
Step 802, determine if St is less than a distance threshold.
And 803, if the current time is less than the preset time, the GPS positioning is not required to be started, and the positioning result of the latest historical record is directly sent to the server.
And step 804, if the value is larger than the preset value, the GPS is started to perform positioning, and the positioning record collection unit 44 is used for processing.
In practical application, the processing sequences of the second positioning processing subunit and the first positioning processing subunit can be interchanged, that is, the judgment is performed according to the moving distance, and if the moving distance is greater than the distance threshold, the judgment is performed according to the WIFI hotspot information and the base station information.
6) The positioning record collection unit 44 performs the steps as shown in fig. 9:
in step 901, the relevant data information for calculating the movement distance is reset and cleared, including St, Ta, Axv, Ayv, Azv, etc. obtained through calculation, and the calculation of the movement distance is restarted.
Step 902, sending the data collected by the current GPS module, the current base station information topwerinfo, and the current WIFI hotspot information list APlist to a server.
And step 903, the server returns a positioning result to the equipment after performing positioning calculation.
And 904, establishing a new record in a storage unit of the historical positioning data, and storing the current base station information, the WIFI hotspot information, the positioning result and the current positioning time in the record.
In summary, the embodiment of the present invention can avoid repeated operation positioning and avoid power consumption and positioning calculation overhead caused by repeated positioning at the same position, thereby improving the standby time of the product and increasing the competitiveness.
