Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, the illustrated embodiments are provided to illustrate the invention and not to limit the scope of the invention.
The invention provides a positioning method based on WiFi, which comprises the following steps:
when the mobile intelligent terminal is in wireless connection with the WiFi positioning tag for the first time, the client running on the mobile intelligent terminal extracts the micro-service module from the micro-service container and deploys the WiFi positioning tag, the WiFi positioning tag deploys and runs the micro-service module to initialize, the WiFi positioning tag is arranged on a positioning target, and the positioning target can be a person or an object.
In the above steps, the mobile intelligent terminal may be an intelligent mobile phone or a tablet computer, and after the user sets the WiFi positioning tag on the positioning target, the user establishes a wireless connection with the WiFi positioning tag through the mobile intelligent terminal of the user, so as to deploy the micro service module, thereby realizing the binding between the mobile intelligent terminal and the WiFi positioning tag. After the deployment of the micro-service module is completed, a user can log in the client through an account to check the WiFi positioning label information and the corresponding positioning target information after the deployment of the micro-service module is completed. The WiFi positioning tag comprises a shell, wherein a PCB is arranged in the shell, and at least a CPU, a WiFi communication module, a battery and a memory are integrated on the PCB. As can be understood by those skilled in the art, the microservice module can be implemented by adopting a corresponding module architecture according to actual needs.
When the WiFi positioning tag cannot be connected to the mobile intelligent terminal, the connection of surrounding connectable equipment is attempted, the connectable equipment comprises transfer equipment and a third-party mobile intelligent terminal, and a client is also installed on the third-party mobile intelligent terminal. And the user corresponding to the third-party mobile intelligent terminal is different from the user corresponding to the mobile intelligent terminal deploying the micro-service module to the WiFi positioning tag. The transit device can be a routing and hotspot device deployed in various places.
When the WiFi positioning tag is connected to the transfer equipment, the micro-service module acquires IP address data of the transfer equipment, the IP address data of the transfer equipment is sent to the mobile intelligent terminal through the transfer equipment, after the mobile intelligent terminal receives the IP address data of the transfer equipment, the IP address data are processed by the client, rough positioning data corresponding to the IP address data are acquired, and a user corresponding to the mobile intelligent terminal can determine the approximate position of the WiFi positioning tag according to the rough positioning data.
When the WiFi positioning tag is connected to a third-party mobile intelligent terminal, the micro-service module executes a preset calculation task to obtain third-party positioning data, the third-party positioning data is obtained by the third-party mobile intelligent terminal through positioning of the third-party mobile intelligent terminal based on a self-contained positioning function, the third-party positioning data is sent to the mobile intelligent terminal through a client of the third-party mobile intelligent terminal, the client processes the third-party positioning data to obtain fine positioning data, and therefore large-range positioning of the WiFi positioning tag is achieved without the help of specific signal transfer transceiver equipment and without the need of building a background server, and the position of a positioning target can be determined even indoors or under the condition that other positioning satellite signals cannot cover the positioning satellite signals.
As an example, before the client extracts the micro service module from the micro service container and deploys the micro service module to the WiFi positioning tag, the client registers the pre-extracted micro service module, where registering the pre-extracted micro service module specifically includes:
the method comprises the steps of obtaining characteristic information of the mobile intelligent terminal, wherein the characteristic information is unique identification information of the mobile intelligent terminal or a user corresponding to the mobile intelligent terminal, such as an IMEI (international mobile equipment identity) serial number, an SN (serial number) number, a user account number and the like, performing function operation on the characteristic information of the mobile intelligent terminal to obtain a first character string, writing the first character string into a micro-service module and storing the first character string. The technical personnel in the field know that the function operation of the mobile intelligent terminal characteristic information to obtain the corresponding character string can be realized by various functions, and the function can be realized by selecting corresponding algorithms according to the requirements in different construction modes of the functions. The contents of the first character strings obtained after the function operation of different mobile intelligent terminal characteristic information are different, but the lengths of the first character strings are the same. In some embodiments, a plurality of items of different types of mobile intelligent terminal feature information may be acquired, the plurality of items of mobile intelligent terminal feature information may be subjected to splicing or splitting recombination processing according to a preset rule, and the processed feature information may be subjected to function operation to acquire the first character string.
And setting the preset calculation task content of the micro-service module according to the acquired characteristic information of the mobile intelligent terminal. The preset calculation task content is used for describing data required to be acquired by the preset calculation task and operation content required to be carried out on the data.
And generating unique identification information of the pre-extracted micro service module and respectively storing the unique identification information to the micro service module and the micro service container.
As a preferred example, the WiFi positioning tag attempts to connect to a surrounding connectable device, specifically including:
and respectively acquiring basic information of all connectable devices, wherein the basic information comprises device information and network information. The connectable devices are all connectable devices within the connection range of the WiFi positioning tag. The device information is used for describing that the connectable device is a transfer device, a mobile intelligent terminal or other devices; the network information is used for describing the current network condition of the corresponding connectable device, including whether to connect with an external network, network speed information and the like.
And respectively calculating the connection utility values of different connectable devices according to the basic information and the preset weight.
In this step, the micro service module calculates connection utility values of different connectable devices according to the acquired device information and network information of each connectable device and preset weights corresponding to each basic information. For example, the preset weight of the mobile intelligent terminal is higher than that of the transit device, and the final connection utility value of the device with the higher network speed is higher for the connectable devices of the same type.
And performing descending sorting on the connectable devices according to the connection utility value calculation result, and sequentially connecting the sorted connectable devices.
According to the method, the connectable devices are sorted in a descending manner according to the connection utility value, so that the connectable devices with higher connection utility values are arranged in the front, and the higher connection utility values can reflect that the corresponding connectable devices have better positioning capability or a better network, so that the WiFi positioning tag can be preferentially connected with the connectable devices capable of positioning the position of the connectable devices more quickly and accurately to send positioning data to the mobile intelligent terminal of the corresponding user.
As an example, when the WiFi positioning tag is connected to the third party mobile intelligent terminal, the micro service module executes a preset computing task, which specifically includes:
and acquiring corresponding mobile intelligent terminal characteristic information according to the content of a preset calculation task, performing function operation on the mobile intelligent terminal characteristic information to acquire a second character string, and comparing the first character string with the second character string to acquire a first result.
And sending the unique identification information to the client, and comparing the received unique identification information with the unique identification information stored in the micro-service container by the client to obtain a second result.
And judging whether the connected mobile intelligent terminal is a third-party mobile intelligent terminal or not according to the first result and the second result, if so, acquiring third-party positioning data, and otherwise, carrying out accurate positioning.
Specifically, when the first result and/or the second result is that the comparison fails, it is indicated that the mobile intelligent terminal connected with the WiFi positioning tag is a third-party mobile intelligent terminal, and a client of the third-party mobile intelligent terminal acquires the current position positioning information of the third-party mobile intelligent terminal; when the first result and the second result are compared and pass, the fact that the mobile intelligent terminal connected with the WiFi positioning tag is the mobile intelligent terminal used by the user corresponding to the WiFi positioning tag is indicated, and accurate positioning is conducted.
When the WiFi positioning tag is connected to the mobile intelligent terminal, the micro-service module unloads the content of the preset calculation task and transmits the content to the client of the mobile intelligent terminal for calculation, and a task result is obtained after the client finishes the preset calculation task.
The mobile intelligent terminal can be a mobile intelligent terminal used by a user corresponding to the WiFi positioning tag, and can also be a third-party mobile intelligent terminal. When the micro-service module is connected to the mobile intelligent terminal, the preset calculation task is unloaded to the mobile intelligent terminal in a calculation unloading mode, and the client side calculates according to the content of the preset calculation task, so that the requirements on the hardware specification and performance of the WiFi positioning tag can be reduced, and the overall cost of the WiFi positioning tag is reduced.
When the mobile intelligent terminal connected with the WiFi positioning tag is judged to be a mobile intelligent terminal used by a user corresponding to the WiFi positioning tag instead of a third-party mobile intelligent terminal according to the first result and the second result, accurate positioning is carried out, and the method specifically comprises the following steps:
and the client calculates the distance between the WiFi positioning tag and the mobile intelligent terminal according to the connecting signal strength value of the WiFi positioning tag and the mobile intelligent terminal.
The client side calculates the direction of the WiFi positioning label relative to the mobile intelligent terminal according to the moving distance and the direction of the mobile intelligent terminal and the signal strength change value between the WiFi positioning label and the mobile intelligent terminal, and guides a user by displaying distance and direction information through a visual interface.
When a positioning target carrying a WiFi positioning tag is far away from a user, so that the WiFi positioning tag cannot be connected to the mobile intelligent terminal, the WiFi positioning tag periodically tries to connect with surrounding connectable equipment, if the WiFi positioning tag is connected to the transfer equipment, IP address information of the transfer equipment is acquired and sent to the mobile intelligent terminal, and a client analyzes the IP address information and acquires position information corresponding to the IP address information, so that the approximate area where the WiFi positioning tag is located is indicated for the user; when the WiFi positioning tag is connected to the third-party mobile intelligent terminal, more accurate positioning data can be directly obtained through a client of the third-party mobile intelligent terminal and sent to the mobile intelligent terminal, and the range of the position of the WiFi positioning tag can be further narrowed according to the positioning data because the connecting range of the WiFi positioning tag is limited; when the user reaches the position near the WiFi positioning tag and the WiFi positioning tag can be connected to the mobile intelligent terminal, the distance and the position of the WiFi positioning tag relative to the mobile intelligent terminal can be obtained in an accurate positioning mode, and therefore the user is helped to find a positioning target.
