Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone positioning, and in particular to a method, system, device and storage medium for real-time positioning of a mobile phone. Background Art

[0002] Mobile phone positioning refers to the technology or service that uses specific positioning technology to obtain the location information and longitude and latitude coordinates of mobile phones or terminal users, and mark the location of the located object on an electronic map; there are two types of positioning technologies, one is based on GPS positioning, and the other is based on the base station positioning of the mobile operator network.

[0003] Existing improvements for mobile phone positioning are usually based on base station positioning of mobile phones. For example, in the Chinese patent with application publication number CN103139901A, a positioning method for TD-SCDMA mobile phone terminals is disclosed. This scheme is to forcibly pull the target mobile phone terminal to the pseudo base station, synchronize to the specific time slot of the TD-SCDMA subframe where the target terminal is located, and measure the specific time slot of the subframe where the target mobile phone terminal is located. It can more accurately identify the location of the target terminal, so that the target mobile phone terminal can be more accurately found and the positioning function is completed. Other improvements for mobile phone positioning are usually based on GPS positioning and network parameters to locate the mobile phone. However, in the existing technology, there will be problems of inaccurate positioning and inability to follow the mobile phone for real-time positioning for the positioning of the mobile phone in motion. When the location of the mobile phone changes, it is impossible to obtain an effective base station in time to locate the mobile phone. At the same time, only using GPS positioning or a fixed communication base station will cause the mobile phone to be unable to accurately update the positioning data of the mobile phone in real time when it moves, so that the obtained positioning data cannot effectively reflect the movement of the mobile phone. In view of this, it is necessary to improve the existing mobile real-time positioning of mobile phones. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems in the prior art to a certain extent. By proposing a real-time positioning method, system, device and storage medium for a mobile phone, the present invention is used to solve the problem in the prior art that the positioning of a mobile phone on the move is inaccurate and it is impossible to follow the mobile phone for real-time positioning. When the position of the mobile phone changes, it is impossible to obtain an effective base station in time to position the mobile phone. At the same time, only using GPS positioning or a fixed communication base station will result in the inability to accurately update the positioning data of the mobile phone in real time when the mobile phone is moving, so that the obtained positioning data cannot effectively reflect the movement status of the mobile phone.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a method for real-time positioning of a mobile phone, comprising:

At the same time, obtaining the mobile area plan and the mobile expansion plan can limit the area where the mobile phone is located, which is conducive to timely replacing the signal base station for locating the mobile phone when the mobile phone moves outside the limited area, thereby making the actual location of the mobile phone obtained when combining GPS positioning and signal base station positioning more accurate, and by continuously replacing the signal base station for locating the mobile phone when the mobile phone is moving, the positioning data obtained can still effectively reflect the movement status of the mobile phone when the mobile phone moves.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1, please refer to Figure 1 As shown, in the first aspect, the present application provides a mobile phone real-time positioning system, including a base station selection module, an actual position determination module and a real-time positioning module:

[0046] The base station selection module is used to obtain the location of the mobile phone based on GPS positioning, recorded as the GPS mobile phone location, and obtain the locatable base stations and the base stations to be used based on the GPS mobile phone location.

[0047] The base station selection module is configured with a positioning base station selection strategy, which includes:

[0048] The location of the mobile phone is obtained based on GPS, and the location obtained by GPS is marked on the map, which is recorded as the GPS mobile phone location; the maximum error distance of GPS positioning is obtained based on the environment where the GPS mobile phone location is located, which is recorded as the GPS error distance;

[0049] In the specific implementation process, the maximum error distance can be set according to the obtained GPS mobile phone position. For example, when the GPS mobile phone position detects that the mobile phone is in an open area, the maximum error distance can be reduced, such as 10 meters; when the GPS mobile phone position detects that the mobile phone is in a tunnel, the maximum error distance can be increased, such as 30 meters;

[0050] Obtain two signal base stations that are relatively close to the location of the GPS mobile phone on the map and record them as locatable base station A and locatable base station B respectively;

[0051] In the specific implementation process, when there are multiple signal base stations close to the location of the GPS mobile phone, signals can be sent to the multiple signal base stations in sequence, and the two signal base stations with shorter time to receive feedback signals are recorded as locatable base station A and locatable base station B;

[0052] Obtain the signal base station that is closest to the locatable base station A and is not the locatable base station B, and record it as the base station A~1 to be used, where the base station A~1 to be used needs to satisfy that the angle between R1 and R2 is an obtuse angle, R1 is the line segment formed by the locatable base station A and the base station A~1 to be used, and R2 is the line segment formed by the locatable base station A and the locatable base station B;

[0053] Obtain the signal base station that is closest to the locatable base station B and is not the signal base station A, and record it as the base station to be used B~1, where the base station to be used B~1 must satisfy that the angle between T1 and T2 is an obtuse angle, T1 is the line segment formed by the locatable base station B and the base station to be used B~1, and T2 is the line segment formed by the locatable base station B and the locatable base station A.

[0054] In the specific implementation process, by making the base station A~1 to be used satisfy that the angle between R1 and R2 is an obtuse angle and making the base station B~1 to be used satisfy that the angle between T1 and T2 is an obtuse angle, the distance between at least one of the base stations A~1 to be used or the base station B~1 to be used and the GPS mobile phone position can be made greater than the distance between any locatable base station and the GPS mobile phone position, so that the radius of the subsequently obtained mobile expansion plan view is greater than the radius of the mobile area plan view;

[0055] The actual position determination module is used to obtain a mobile area plan and a mobile expansion plan based on a locatable base station and a base station to be used; and to accurately locate the mobile phone based on the locatable base station to obtain the actual position of the mobile phone.

[0056] The actual location determination module is configured with a regional positioning establishment strategy and an actual location determination strategy; the regional positioning establishment strategy includes:

[0057] Obtain the distances of the locatable base station A, the locatable base station B, the base station A~1 to be used, and the base station B~1 to be used from the GPS mobile phone position respectively, and record them as the locatable distance AJL, the locatable distance BJL, the distance A~1 to be used, and the distance B~1 to be used respectively;

[0058] The maximum value of the locatable distance AJL and the locatable distance BJL is recorded as the area radius; the maximum value of the distance to be used A~1JL and the distance to be used B~1JL is recorded as the expansion radius;

[0059] The circle with the GPS mobile phone position as the center and the area radius as the radius in the map is recorded as the mobile area plan; the circle with the GPS mobile phone position as the center and the expansion radius as the radius in the map is recorded as the mobile expansion plan.

[0060] Use a mobile phone to send a positioning signal to a locatable base station A, and obtain the distance between the mobile phone and the locatable base station based on the feedback signal of the locatable base station A, which is recorded as the locatable distance A; use a mobile phone to send a positioning signal to a locatable base station B, and obtain the distance between the mobile phone and the locatable base station based on the feedback signal of the locatable base station B, which is recorded as the locatable distance B;

[0061] A plane rectangular coordinate system is established, which is recorded as the regional positioning coordinate system, wherein the units of the X-axis and the Y-axis of the regional positioning coordinate system are both in meters; the GPS mobile phone position, the locatable base station, the base station to be used, the mobile area plan and the mobile expansion plan are placed in equal proportions in the regional positioning coordinate system; in the mobile area plan, a circle is made with the locatable base station A as the center and the locatable distance A as the radius, which is recorded as positioning circle A; a circle is made with the locatable base station B as the center and the locatable distance B as the radius, which is recorded as positioning circle B; a circle is made with the GPS mobile phone position as the center and the GPS error distance as the radius, which is recorded as the error circle.

[0062] In the specific implementation process, please refer to Figure 3 as well as Figure 4 As shown, the circle corresponding to GG0 is the error circle, the circle corresponding to GG1 is the moving area plane, the circle corresponding to GG2 is the moving expansion plane, the point corresponding to △ is the location of the locatable base station, the point corresponding to □ is the location of the base station to be used, the point corresponding to GG3 is the GPS mobile phone location, GG4 and GG5 are positioning circle A and positioning circle B. Through analysis, it can be obtained that there is an intersection point GG6 between positioning circle A and positioning circle B and it does not coincide with the GPS mobile phone location. Then, the midpoint of the line segment obtained by connecting point GG6 with the GPS mobile phone location is recorded as the mobile phone's pending location, that is, point GG7. Figure 4 The obtained point GG7 is within the error circle, so GG7 can be recorded as the actual position of the mobile phone;

[0063] The actual location determination strategy includes: when there is an intersection between positioning circle A and positioning circle B and the number of intersections is 1, the intersection between positioning circle A and positioning circle B is recorded as the base station mobile phone location; when the base station mobile phone location coincides with the GPS mobile phone location, the base station mobile phone location is recorded as the actual location of the mobile phone; when the base station mobile phone location does not coincide with the GPS mobile phone location, the midpoint of the line segment obtained by connecting the base station mobile phone location with the GPS mobile phone location is recorded as the mobile phone's pending location.

[0064] In the specific implementation process, by combining the signal base station and GPS positioning, the obtained mobile phone location can be made more accurate. At the same time, selecting two signal base stations with a close distance through the above analysis can further improve the accuracy of the obtained mobile phone location;

[0065] When there are intersections between positioning circle A and positioning circle B and the number of intersections is 2, the intersections between positioning circle A and positioning circle B are recorded as base station pending position 1 and base station pending position 2 respectively, and the midpoint of the triangle formed by the GPS mobile phone position, base station pending position 1 and base station pending position 2 is recorded as the mobile phone pending position;

[0066] When there is no intersection between positioning circle A and positioning circle B, the point on positioning circle A closest to the GPS mobile phone position is recorded as the near point of circle A, the point on positioning circle B closest to the GPS mobile phone position is recorded as the near point of circle B, and the midpoint of the triangle formed by the near point of circle A, the near point of circle B and the GPS mobile phone position is recorded as the pending position of the mobile phone;

[0067] After obtaining the pending position of the mobile phone, when the pending position of the mobile phone is within the error circle, the pending position of the mobile phone is recorded as the actual position of the mobile phone; when the pending position of the mobile phone is outside the error circle, the point on the error circle closest to the pending position of the mobile phone is recorded as the actual position of the mobile phone. In this embodiment, the actual position of the mobile phone is the position of the mobile phone obtained through analysis;

[0068] In the specific implementation process, when the pending position of the mobile phone is within the error circle, it means that there may be an error in GPS positioning, but the error is within the allowable error range, so the pending position of the mobile phone can be recorded as the actual position of the mobile phone; when the pending position of the mobile phone is outside the error circle, it means that the position of the mobile phone obtained by GPS positioning and the position of the mobile phone obtained by the signal base station have a large error, and the point on the error circle closest to the pending position of the mobile phone can be recorded as the actual position of the mobile phone through compromise. When there are other methods for locating the mobile phone in actual situations, the actual position of the mobile phone can be further calibrated according to the method in the actual situation combined with the pending position of the mobile phone;

[0069] The real-time positioning module is used to perform real-time positioning when the mobile phone moves based on the base station to be used.

[0070] The real-time positioning module is configured with a mobile real-time positioning strategy, which includes: obtaining the actual position of the mobile phone at every standard moving time, when the actual position of the mobile phone is within the mobile expansion plane and not within the mobile area plane, a circle is drawn with the real-time position of the mobile phone at this time as the center and the GPS error distance as the radius, which is recorded as the transfer error circle;

[0071] In the specific implementation process, the standard moving time can be determined according to the actual moving speed of the mobile phone, ensuring that the actual position of the mobile phone can be obtained at least once when the mobile phone is in the moving expansion plane map and not in the moving area plane map;

[0072] In the specific implementation process, when the actual position of the mobile phone is within the mobile expansion plane map and not within the mobile area plane map, it means that the locatable base station at this time may be farther away from the mobile phone. Therefore, the locatable base station should be replaced so that the distance between the replaced locatable base station and the mobile phone is closer, thereby making the obtained positioning data more accurate.

[0073] Replace the locatable base station A with the locatable base station closest to the actual location of the mobile phone, replace the locatable base station B with the base station to be used corresponding to the locatable base station closest to the actual location of the mobile phone, and obtain the latest locatable base station A and the base station to be used of the locatable base station B.

[0074] In the specific implementation process, in this embodiment, whenever a locatable base station is replaced, the base station to be used corresponding to the replaced locatable base station and the corresponding mobile area plan and mobile expansion plan are immediately obtained, and real-time replacement is performed in the regional positioning coordinate system;

[0075] When the locatable base station A and the locatable base station B are replaced, the mobile area plan and the mobile expansion plan are obtained based on the replaced locatable base station A and the locatable base station B, and the actual position of the mobile phone is immediately obtained. When the actual position of the mobile phone is within the transfer error circle, the actual position of the mobile phone is continuously obtained at standard moving time intervals, and the positioning base station A and the positioning base station B are replaced when the actual position of the mobile phone is within the mobile expansion plan and not within the mobile area plan;

[0076] In the specific implementation process, when the actual position of the mobile phone is within the transfer error circle, it means that the error between the position data obtained based on the replaced locatable base station and the position data obtained based on the replaced locatable base station is within the allowable error range, so the replaced locatable base station can continue to be used to locate the position of the mobile phone in real time;

[0077] When the actual location of the mobile phone is not within the transfer error circle, the existing locatable base station A and locatable base station B are deleted, the GPS mobile phone location at this time is obtained, and the two signal base stations that are closer to the GPS mobile phone location are recorded as locatable base station A and locatable base station B. The actual location of the mobile phone is continuously obtained at standard moving time intervals based on the locatable base stations, and the positioning base station A and positioning base station B are replaced when the actual location of the mobile phone is within the moving expansion plane map and not within the moving area plane map;

[0078] During the specific implementation process, when the actual location of the mobile phone is not within the transfer error circle, it means that the error between the location data obtained based on the replaced locatable base station and the location data obtained based on the replaced locatable base station is large. In order to ensure the accurate positioning of the mobile phone, the locatable base station should be re-acquired for subsequent analysis.

[0085] Obtain the signal base station that is closest to the locatable base station B and is not the signal base station A, and record it as the base station to be used B~1, where the base station to be used B~1 must satisfy that the angle between T1 and T2 is an obtuse angle, T1 is the line segment formed by the locatable base station B and the base station to be used B~1, and T2 is the line segment formed by the locatable base station B and the locatable base station A.

[0089] The maximum value of the locatable distance AJL and the locatable distance BJL is recorded as the area radius; the maximum value of the distance to be used A~1JL and the distance to be used B~1JL is recorded as the expansion radius;
