With continued reference to fig. 2, a flow 200 of some embodiments of an information push method according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The information pushing method comprises the following steps:
In some embodiments, the execution subject of the information pushing method (such as the computing device 101 shown in fig. 1) may obtain the positioning result by:
in the first step, the execution body may detect a positioning application signal sent by the target device. Here, the positioning application signal may be a signal generated when a positioning function is triggered. In response to detecting the positioning application signal, the execution main body may calculate a time for receiving the signal based on a time when the target device transmits the positioning application signal and a time when the target device receives the signal transmitted by the communication base station. Further, the execution body may obtain a time when the target device receives a predetermined number of signals, and obtain a time set.
In the second step, the executing entity may calculate a distance between the target device and each of the predetermined number of communication base stations based on the speed of signal transmission and the obtained time set. Thus, a set of distances is obtained.
And thirdly, the executing body takes each communication base station in the preset number of communication base stations as a sphere center respectively. And respectively taking the distance between the target device and each communication base station as a radius to generate a preset number of spheres. The execution body may determine an intersection point of a predetermined number of spheres as the location of the target device. The execution body may then determine the position as a first positioning result. The predetermined number may be at least four.
Fourthly, the executing body can acquire the position information of each communication base station by using a wired connection mode or a wireless connection mode. Thus, the execution body can obtain the position information set. Here, the location information may be spatial coordinates of the communication base station.
In the fifth step, the executing body may perform coordinate transformation based on the distance set and the second position information set to determine the coordinates of the target device. And finally determining the coordinate as a second positioning result.
And sixthly, the execution subject can weight the first positioning result and the second positioning result according to preset weights to obtain new coordinate information. Then, the execution subject may determine the coordinate information as a positioning result.
In some optional implementations of some embodiments, the execution body may use existing positioning technology to position the target device. As an example, the existing positioning technology may be a Beidou navigation positioning technology or a GPS positioning technology.
In some embodiments, the execution body may obtain the addressing result by: the first step, the execution subject may use the positioning result as an addressing range, and determine the number of base stations in the addressing range; secondly, the execution main body can acquire the downlink pilot signals of each base station corresponding to the target equipment in the addressing range to obtain a downlink pilot signal set; the downlink pilot signal may be a pilot signal of a downlink channel; thirdly, the execution main body can obtain the arrival time difference of each downlink pilot signal according to the arrival time of the downlink pilot signals to obtain a time difference set; fourthly, the execution main body can determine the distance between the target device and each base station according to the arrival time difference and the signal transmission speed of each downlink pilot signal; fifthly, the execution main body can acquire the position coordinates of the base station; sixthly, the execution main body can determine the position information of the target equipment according to the distance between the target equipment and each base station and the position coordinates of the base stations; a seventh step, the execution subject may determine the location information as a second addressing result; eighthly, the executing body may obtain the signal strength of each wireless access point of a third predetermined number of wireless access points corresponding to the second addressing result to obtain a signal strength set; ninthly, the executing body may input each signal strength in the signal strength set to a pre-trained signal attenuation model, so as to obtain a distance corresponding to each wireless access point; tenth, the executing agent may obtain location information of each wireless access point; eleventh, the executing body may use each wireless access point as a sphere center, and use a distance corresponding to each wireless access point as a radius, to generate a predetermined number of spheres; in the twelfth step, the execution body may determine an intersection of a predetermined number of spheres as a location of the target device, and determine the location as a third addressing result.
The addressing set forth above may be a technique for locating an address (e.g., an IP address) of a determined target device. The pre-trained signal attenuation model may be obtained by training a sample signal strength of a signal propagated by the wireless sensor as an input of the satellite simulator, and a sample distance corresponding to the sample signal strength as an expected output.
In some optional implementations of some embodiments, the target device is addressed, the location of the target device may be further determined, and the interaction of multiple base stations may improve the accuracy of the positioning.
In some embodiments, the execution subject may select, as the preselected region, a region meeting a preset condition from the region library based on the addressing result. Then, the execution body may combine the area name, the area code, the area type information, the area location information, and the latitude and longitude information of the preselected area to generate combined information. Finally, the execution body may convert and rewrite the candidate information based on a pre-constructed short message information coding conversion table to obtain the short message information. The short message information code conversion table may be a table for representing a corresponding conversion relationship between information and codes. The preset condition may be whether the area is the addressing result.
In some optional implementations of some embodiments, the region library may include, but is not limited to, at least one of: area name, area code, area category information, area location information, and latitude and longitude information. The region type information may be a type to which the region belongs. As an example, the area category information may be "the area a is a business area".
In some optional implementations of some embodiments, the region library may be generated by: based on a preset dividing mode, carrying out region division on a target region to obtain at least one region; generating the name of each region in the at least one region based on a preset naming mode to obtain a region name set; acquiring the position information of each area to obtain an area position information set; generating a code of each region based on the region name set and the region position information set to obtain a region code set; generating a tree structure diagram of the target area based on the area name set, the area location information set and the area code set; and combining the region name set, the region position information set, the region code set and the tree structure chart to obtain the region library.
In some optional implementation manners of some embodiments, the name and the code of the area where the target device is located are obtained through a pre-constructed area library. The content of the generated short message information is more abundant.
In some optional implementations of some embodiments, the method further comprises: encrypting the short message information based on a preset public key to generate a short message information ciphertext; and determining the short message information ciphertext as the short message information of the target equipment.
In some optional implementation manners of some embodiments, the generated short message information may establish a better interaction relationship with the cloud terminal. And the user can know the position information of the target equipment conveniently by means of the voice presentation mode.
In some optional implementations of some embodiments, based on the addressing result, the execution subject may calculate location information (in contrast to a pre-generated area library) using a cloud. And then, pushing the position information to the cloud terminal. In addition, the position information is calculated by utilizing the cloud, so that unnecessary delay conditions are avoided, and the positioning speed is increased.
And 204, pushing the short message information to the target equipment based on a preset pushing mode.
In some embodiments, the predetermined pushing manner may be a manner of converting the short message information into a vector and then pushing the vector. The execution main body can perform word segmentation on the short message information to obtain at least one word. Then, the execution body may perform word embedding on each word in the at least one word to obtain a word vector set. And then, the execution main body can splice each word vector in the word vector set to obtain a short message information vector. Finally, the execution agent may push the short message information vector to the target device.
The input word vector set forth above may be a word vector resulting from word embedding of the input word. Word embedding is the general term for Language models and characterization learning techniques in Natural Language Processing (NLP). Conceptually, it refers to embedding a high-dimensional space with dimensions of the number of all words into a continuous vector space with much lower dimensions, each word or phrase being mapped as a vector on the real number domain. Specifically, a word vector (word vector) may be a vector in which a word or phrase is mapped to a real number by a word embedding method. Conceptually, it involves mathematical embedding from a one-dimensional space of each word to a continuous vector space with lower dimensions.
In some optional implementation manners of some embodiments, vector conversion is performed on the short message information before pushing, so that the occupied space of the information can be reduced. Thus, the time consumption of pushing is reduced. The efficiency of whole propelling movement is improved.
In some optional implementation manners of some embodiments, a positioning system for generating short message information may be constructed based on the above steps. As an example, first, a positioning chip may be mounted to a target terminal (cloud terminal); secondly, a positioning program can be installed to a target terminal (cloud terminal), and the specific implementation of the positioning program and the technical effects brought by the positioning program can refer to the steps; thirdly, responding to the activation of a positioning program, detecting a positioning request (establishing a connection relation with a cloud end); fourth, in response to detecting the positioning request, the positioning procedure is started (calculating the position information using the cloud).
In some optional implementation manners of some embodiments, in response to the execution main body pushing the short message information vector to the target device, the target device may receive a feedback calculation result of the cloud.
One of the above-described various embodiments of the present disclosure has the following advantageous effects: the location of the target device may be determined by the location of the target device. The target device is addressed in various ways and the result of the positioning is corrected using the addressing result. Thus, more accurate position information can be obtained. And then, according to the addressing result and a pre-generated area library, area comparison and area selection are carried out to determine the area of the target equipment. Further, short message information about the area in which the mobile terminal is located can be generated. The generated short message information is beneficial to improving the user experience through a voice presentation mode. And finally, pushing the generated short message information to the target terminal according to a preset pushing mode. The method disclosed by the invention can also be applied to the construction of a positioning system for generating short message information, so that the region can be conveniently known and managed by workers.
With continued reference to fig. 3, a flow diagram 300 of further embodiments of an information push method according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The information pushing method comprises the following steps:
In some embodiments, the specific implementation and technical effects of steps 301 and 302 may refer to steps 201 and 202 in the embodiments corresponding to fig. 2, which are not described herein again.
And step 303, selecting an area meeting preset conditions from the area library as a preselected area based on the addressing result.
In some embodiments, the execution subject may select a pre-generated region bank according to the obtained addressing result. Then, the execution subject may select an area that meets a preset condition as a preselected area. Here, the predetermined condition may be a region where the above-described addressing result is satisfied.
And 304, generating preselected short message information based on the area name, the area code, the area category information, the area position information and the latitude and longitude information of the preselected area.
In some embodiments, the execution subject may combine the area name, the area code, the area category information, the area location information, and the latitude and longitude information of the preselected area to obtain combined information. The execution body can convert and rewrite the combined information based on a pre-constructed short message information coding conversion table to obtain the pre-selected short message information.
And 305, encrypting the preselected short message information based on the preset public key to generate a short message information ciphertext.
In some embodiments, the execution subject may encrypt the pre-selected short message information based on a preset public key. The predetermined public key may be a parameter input in a predetermined algorithm for converting a plaintext of the information into a ciphertext. The preset public key has a corresponding preset private key. The execution body may encrypt the preselected short message information using the following formula:
m ^ e ^ c (mod n). Wherein m represents the pre-selected short message information, and m is an integer less than n (when m is a character string, a value corresponding to the ASCII code of m is taken); n and e are components of a preset public key, and the preset public key is expressed as (n, m); c is the encrypted pre-selected short message information ciphertext.
The value corresponding to the ASCII (american Standard Code for Information exchange) Code set forth above may be the value corresponding to a character string in an ASCII Code table.
As an example, when the preset public key is (3233, 17) and the value of the preselected short message information is 65, the preset public key and the value of the preselected short message information are substituted into the above formula to obtain:
65^17 ^ c (mod 3233). Thus, c is 2790. Then "2790" may be the encrypted ciphertext of the value "65" of the preselected short message information.
In some embodiments, the execution subject may determine the short message information ciphertext as the short message information of the target device.
In response to determining that the preselected region selection is complete, a selection complete time point is determined, step 307.
In some embodiments, the execution body may determine a time point when the selection is completed as the selection completion time point in response to determining that the pre-selection area selection is completed.
Based on the region coding of the preselected region and the selection completion time point, a feedback code is generated, step 308.
In some embodiments, the execution body may rewrite the region coding of the pre-region and the selection completion time point to generate the feedback coding. As an example, the region code of the preselected region may be "sjfxxyy". Where "SJFJ" denotes that the position of the preselected area is at the boundary of the commercial area and the residential area, and "XXYY" denotes coordinates. The selection completion time point may be "number 6 of 10 months in 2019, point 13, point 21". The feedback code generated by the overwrite may be "sjfxxyy 1910061321".
In some embodiments, the execution body may push the feedback encoding to the target device.
In some embodiments, the execution body may decrypt the short message information first. And then displaying the decrypted short message information and the feedback code on a display of the target equipment. The execution main body may decrypt the short message information based on a private key corresponding to the preset public key by using the following formula:
c ^ d ^ m (mod n). The formula can be expressed as that the remainder of dividing the d-th power of the ciphertext by n is the decrypted short message information.
As an example, the private key corresponding to the preset public key is (3233, 2755), and the encrypted ciphertext c of the pre-selected short message information is "2790". The private key and the ciphertext are substituted into the formula to obtain:
2790^ d ^ 65(mod 3233) this gives d ^ 2753. Then "2753" may be the decrypted short message information.
One of the above-described various embodiments of the present disclosure has the following advantageous effects: the position of the target device is determined by positioning and addressing the target device. Then, based on the location of the target device and a pre-generated area library, short message information of the target device for the current positioning can be generated. By encrypting the short message information, the safety factor in the information transmission process can be improved, and potential safety hazards caused by information leakage are avoided.
