Detailed Description
Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, this example provides a bluetooth assisted positioning car returning method, which includes the following steps:
step S1, uploading the mobile phone positioning information after the network vehicle returning fails;
step S2, matching the uploaded mobile phone positioning information with a nearby returning point, verifying whether the distance between the mobile phone positioning information and the returning point is within a preset distance range, and if so, returning the vehicle through the returning point; if not, jumping to step S3;
step S3, searching all the Bluetooth devices around the mobile phone through the mobile phone, and uploading the numbers of all the Bluetooth devices around the mobile phone to a background;
step S4, carrying out verification statistics on all the Bluetooth devices around the mobile phone through a background to obtain a Bluetooth device set subjected to verification statistics;
and step S5, calculating the coordinates of the Bluetooth device set to obtain comprehensive coordinates, and matching parking points by taking the comprehensive coordinates as the position of the current device to realize returning.
In step S1, a network car is returned in a conventional manner, after the network car is failed to be returned, the bluetooth is connected through the mobile phone, the mobile phone positioning information is uploaded, and in step S2, the matching is performed through the mobile phone positioning information to realize the car returning through a car returning point near the mobile phone, so as to try the first matching car returning. And the nearby returning points refer to returning points closest to the mobile phone positioning information or returning points with the distance between the mobile phone positioning information and the returning points within a preset distance range, and Bluetooth returning is realized through the returning points combined with mobile phone accessories.
If the first matching is failed, the method goes to the step S3 to the step S5, the mobile phone positioning and a plurality of Bluetooth devices (the Bluetooth devices are also called as terminal devices) around the mobile phone are used for positioning and collecting, a plurality of groups of data are analyzed and synthesized by an algorithm to form new positioning data, and then the new positioning data and the returning points are matched, so that the reliability of the returning longitude and latitude is greatly improved, and the positioning dependence on a single terminal device is reduced.
In step S3, when the distance between the mobile phone location information and the returning location is greater than the preset distance range, the mobile phone location information fails to be verified, the verification failure information is returned to the mobile phone, and an instruction is issued to the mobile phone, so as to search all bluetooth devices around the mobile phone. The predetermined distance range in this example is preferably less than 100 meters.
Step S4 in this example includes the following substeps:
step S401, excluding Bluetooth equipment without registration information;
step S402, according to the historical positioning information corresponding to the Bluetooth equipment, eliminating the Bluetooth equipment with positioning failure;
step S403, eliminating the Bluetooth equipment with track offset according to the mobile phone positioning information;
and step S404, obtaining a Bluetooth device set after verification and statistics.
In this embodiment, the bluetooth device without registration information refers to a bluetooth device that is not registered in the background, and such terminal devices that do not belong to the same platform are excluded first, which is implemented through the step S401; then, according to the historical positioning information, excluding the terminal device with failed positioning, which is often a faulty device and should be excluded, which is implemented through the step S402; then, the mobile phone positioning information is collected and processed, it is mainly verified whether the distance between the bluetooth devices is greater than 100 meters, the bluetooth devices with too large distance are regarded as the trace offset and need to be discarded, and the trace offset is eliminated, which is implemented through the step S403.
It is worth mentioning that the situation that positioning offset exists in a plurality of bluetooth devices acquired by a mobile phone may cause large offset after all positioning comprehensive processing, and therefore, in this example, a bluetooth device which is more than 100 meters away from the mobile phone positioning information is excluded according to the distance between the bluetooth device and the mobile phone positioning information in the step S403, on the basis of realizing positioning return by adopting a comprehensive coordinate manner, the reliability of a comprehensive coordinate is improved by the bluetooth device which excludes track offset, for example, verification is performed through stored historical track points, if the distance between the current positioning and the last positioning point exceeds 1000 meters, the current positioning is regarded as positioning offset, and when the mobile phone works normally, the terminal devices such as the bluetooth device upload positioning information every 3S; therefore, these technical means are not the conventional means in the field, and the reliability of the integrated coordinate can be effectively improved by the simple arrangement.
In this example, in step S403, a bluetooth device whose distance from the mobile phone location information is greater than the preset distance range is preferably defined as a bluetooth device with a track offset.
In step S4, the background stores historical positioning information of the bluetooth device, and analyzes the historical positioning information according to the bluetooth device number and the mobile phone positioning information, and moves the bluetooth device with a failure in positioning out of the bluetooth device set.
It is also worth mentioning how to obtain the real-time positioning and the effectiveness and accuracy of the positioning of the bluetooth device, which is a technical problem for those skilled in the art; the solution adopted in this example is that the background eliminates the bluetooth device with the positioning failure through the positioning of the network and the comprehensive coordinates and through the analysis of the historical positioning information, and the process of eliminating the bluetooth device with the positioning failure is as follows: verifying through the stored historical track points, if the distance between the current positioning point and the last positioning point exceeds 1000 meters, regarding the current positioning point as a positioning offset point, uploading positioning information every time a fixed time interval threshold value passes, and if the positioning offset point on the same day exceeds a preset offset point number threshold value, judging that the Bluetooth equipment is the Bluetooth equipment with a positioning fault; the time interval threshold is a set time interval for collecting the positioning information, is preferably 3S, and can be adjusted to other time interval thresholds according to actual needs; the threshold value of the number of the offset points is the upper limit of the number of the positioning offset points, preferably 50, and may be adjusted to other numbers according to actual needs. That is to say, on the basis of adopting the comprehensive coordinates, historical positioning information is also analyzed, and faulty bluetooth equipment with positioning failure is eliminated, so that the positioning timeliness of the bluetooth equipment can be effectively guaranteed, which is not a means used by technicians in the field.
In step S5, a polygon is formed by coordinates of each bluetooth device in the bluetooth device set, so as to obtain a center position of the polygon, and the coordinates of the center position are used as the integrated coordinates, which is a process of calculating the coordinates of the bluetooth device set to obtain the integrated coordinates in this example.
In the embodiment, after the car returning is successful, the car returning success prompt is returned to the mobile phone, and the car returning record is stored in the historical positioning information, so that the next historical positioning information analysis is realized conveniently.
The embodiment also provides a Bluetooth auxiliary positioning car returning system, which adopts the Bluetooth auxiliary positioning car returning method.
In summary, in this embodiment, a network vehicle is returned in a conventional manner, after the network vehicle is returned in a failure, the network vehicle is matched through the mobile phone positioning information, and the vehicle is returned through the vehicle returning points near the mobile phone, after the vehicle returning in the failure, the positioning integration is performed through the plurality of bluetooth devices around the mobile phone, and the vehicle returning is realized through the integrated comprehensive coordinates, so that the dependency of the vehicle returning on the positioning of a single terminal device is effectively reduced, thereby reducing the problem that the vehicle cannot be returned due to positioning errors, environmental factors, device faults and the like, effectively improving the accuracy of vehicle returning positioning matching, even if a certain terminal device goes out of a bank and goes wrong, the vehicle returning can be realized through the coordination and integration of the plurality of bluetooth devices, the error reporting rate and the maintenance rate of a shared vehicle are reduced, and the reliability and the applicability of the product are improved.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
