Namely, the position data of the first terminal can be rapidly and safely inquired, and the user experience is improved. In addition, the small program is adopted to identify the bar code information, the workload of developing a special application program aiming at the system or equipment model is reduced, and the production and upgrading efficiency of a developer is improved.
The following describes implementation details of the query location method according to this embodiment in detail, and the following is only provided for facilitating understanding of the implementation details provided for the present embodiment, and the implementation process may refer to fig. 2 when the second terminal has an access right.
In step 101, the second terminal obtains barcode information, where the barcode information is used to trigger the second terminal to connect to the server, and the barcode information includes identity information of the first terminal. The acquisition is that the second terminal can receive the bar code information, and after the second terminal identifies the bar code information, the second terminal can be triggered to initiate a connection request to the server. The second terminal can run small programs, such as intelligent terminals like mobile phones; the first terminal is a terminal which needs to inquire position information in practical application, such as an interphone, a locator or a forensic apparatus, can be in communication connection with the server, has a position identification function, and can report the position information of the first terminal to the server so as to store data of the server.
In one example, the barcode information may be embedded in or attached to a terminal housing when the first terminal is shipped from a factory, or the first terminal may locally integrate the barcode information including the identity information of the first terminal through a self-contained application program.
The step can provide the identity information of the first terminal to the second terminal, and simultaneously provide a specific channel for realizing data interaction with the server to the second terminal by utilizing the bar code information.
In step 102, the second terminal identifies the barcode information through the applet, and sends a verification request to the server, where the verification request includes identity information of the second terminal.
The barcode information is obtained in the previous step, then the small program operated by the second terminal is adopted to identify the barcode information, and the identity information of the second terminal can be sent to the server for the server to verify the identity information of the second terminal. The small program is matched with the bar code information and can analyze data in the bar code information, and due to the small program, the second terminal can identify the bar code information and send verification information containing identity information of the second terminal to the server, so that the server can verify the authority of the second terminal. The mobile phone terminal analyzes the bar code information through the small program, and is used for finishing the steps of authentication and login with the server terminal and verifying whether the second terminal has the authority to check the position data in the server.
The applet is generally available in a full platform, and does not limit the operating system or model of the second terminal; compared with a method for inquiring the position information by using an applet, the method for inquiring the position information reduces software development cost of a specific system and installation and learning cost of a user compared with a method for inquiring the position information of a terminal by using application software corresponding to a terminal system (for example, Android Application Package (APK) is installed on an Android machine or ios application software is installed on apple equipment); compared with a mode of inquiring the position information by logging in the client or the webpage, the method reduces the use cost of the client and the webpage for developing and memorizing the specific logging-in equipment such as a computer required by a user.
In the step, the second terminal identifies the bar code information through the small program, initiates the identity verification of the second terminal to the server, and judges whether the second terminal has the permission to access, so as to ensure the security of the data of each terminal in the server.
In step 103, after receiving the authentication request, the server determines the authority of the second terminal according to the identity information of the second terminal, and if the second terminal has the access authority, the server feeds back a message that the authentication is passed to the second terminal.
In the specific implementation process, after receiving the verification request of the second terminal, the server analyzes the identity information of the second terminal contained in the verification request, identifies the authority of the second terminal according to the preset access-allowed data, and feeds back a message that the verification is passed to the second terminal if the second terminal is judged to have the access authority according to the identity authority of the second terminal; if the second terminal does not have the access right according to the identity right of the second terminal, the process of the inquiry and positioning is automatically finished without feedback, or the information of the verification failure is fed back, and the process of the inquiry and positioning is finished at the same time.
And the message passing the verification can trigger the second terminal to send a request for inquiring the specific position.
The step is mainly that the server identifies and judges the access authority of the second terminal so as to ensure the safety of the position data in the server. If the second terminal has the access right, the server triggers the feedback information trigger and then requests specific position data.
In step 104, after receiving the message that the verification passes, the second terminal sends a request for inquiring the location to the server, wherein the request for inquiring the location includes the identity information of the first terminal; and the identity information of the first terminal is obtained by analyzing the bar code information by the small program.
In one example, after receiving the message that the verification is passed, the second terminal can send a request for querying the location to the server by itself, where the request carries the identity information of the first terminal analyzed from the barcode information. The bar code information is identified by the applet when the verification request is sent to the server side, and the applet can analyze the bar code information, including the identity information of the first terminal, so that the second terminal is in a state of knowing the identity information of the first terminal when receiving the verification passing feedback. And further sending a request containing the identity information of the first terminal to the server for inquiring a position result corresponding to the identity information of the first terminal.
In this step, the second terminal sends a request containing the position information of the first terminal to the server. And the terminal is used for requesting the position information of the first terminal from the server by adopting the identity information of the first terminal after judging that the second terminal has the inquiry authority so as to realize the purpose of inquiry positioning.
In step 105, after receiving the request for querying the location, the server queries the location result of the first terminal through the identity information of the first terminal, and sends the location result to the second terminal.
In a specific implementation, the first terminal has a positioning function, for example, a positioning module is present, and is configured to feed back the position information of the first terminal to the server in real time. When the second terminal sends a query request to the server, the server queries the real-time position coordinates of the first terminal in the server according to the identity information of the first terminal carried in the query request.
In one example, the position result queried by the second terminal includes real-time position coordinates and/or track information, and the server can store the position information within a certain time range, that is, can embody the motion track of the first terminal. When the second terminal queries, the real-time position coordinates of the first terminal can be fed back, and the track of the first terminal can also be fed back, wherein the first terminal can select which position result is received or specifically received at the same time according to actual requirements. The diversity of the position result reflects the position state of the first terminal in many aspects, meets the query requirement of a user, and improves the user experience.
The step is a process that the server queries according to the request of querying the position of the second terminal, and is used for querying the position result of the first terminal in the data of the server, providing the position of the first terminal to be queried for the user, and meeting the query positioning requirement of the user.
In step 106, the second terminal displays the position result on the applet. Since the second terminal is initially connected to the server through the applet, the feedback data of the query result of the server will be fed back to the applet. In one example, the applet can display the specific positions of the first terminal and the second terminal simultaneously through an operable visual map, so that the position information is visualized and is convenient for a user to judge and read.
For convenience of understanding, the following description will be given by taking the first terminal as an intercom and the second terminal as a mobile phone:
the second terminal is a mobile phone terminal capable of running the small program, the first terminal is an interphone, and the barcode information can be preset when the interphone leaves a factory. When the embodiment is adopted, the barcode information needs to be acquired, so that the mobile phone terminal can contact or recognize the barcode information, the barcode information is recognized by using an applet in the mobile phone terminal, the applet is matched with the barcode information and is used for analyzing data in the barcode information, and due to the existence of the applet, the mobile phone terminal can be triggered to send a verification message containing identity information of the mobile phone terminal to a server, so that the server can verify the authority of the mobile phone terminal. Namely, the mobile phone terminal analyzes the bar code information through the small program, and completes the steps of authentication and login with the server side, so that the mobile phone terminal has the authority to check the position result of the network side.
The barcode information also comprises identity information of the interphone, after the server authenticates the mobile phone terminal, namely the mobile phone terminal completes login action, the terminal receives login completion information sent by the server and can send a position inquiry request containing the identity information of the interphone through a communication channel with the server, and the server searches a position result of the interphone according to the identity information of the interphone in the position inquiry request, sends the real-time position of the interphone to the mobile phone terminal and displays the position result in the applet.
Compared with the related technology, the bar code information is used for triggering the second terminal to initiate the action of connecting with the server, the second terminal runs the applet to identify the bar code information so as to log in the server, the position result of the first terminal analyzed from the bar code information is inquired, a user does not need to learn complicated inquiry steps, and the operation process is simple; meanwhile, the server needs to perform identity authentication on the second terminal in the login process, so that the safety of the equipment position information can be ensured. Namely, the position data of the first terminal can be rapidly and safely inquired, and the user experience is improved. In addition, the small program is adopted to identify the bar code information, the workload of developing a special application program aiming at the system or equipment model is reduced, and the production and upgrading efficiency of a developer is improved.
The second embodiment of the invention relates to a query positioning method. The method comprises the following specific steps:
step 201, a first terminal requests bar code information from a server through identity information of the first terminal;
step 202, the second terminal scans the first terminal to obtain bar code information, the bar code information is used for triggering the second terminal to be connected with a server, and the bar code information comprises identity information of the first terminal;
step 203, the second terminal identifies the bar code information through the applet and sends a verification request to the server, wherein the verification request comprises the identity information of the second terminal;
step 204, after receiving the verification request, the server judges the authority of the second terminal according to the identity information of the second terminal, and if the second terminal has the access authority, the server feeds back a message that the verification is passed to the second terminal;
step 205, after receiving the message that the verification passes, the second terminal sends a request for inquiring the position to the server, wherein the request for inquiring the position includes the identity information of the first terminal; the identity information of the first terminal is obtained by analyzing the bar code information by the small program;
step 206, after receiving the request for inquiring the position, the server inquires the group corresponding to the first terminal according to the identity information of the first terminal;
step 207, the server queries the position result corresponding to the group and sends the position result to the second terminal;
the second terminal displays the position result on the applet, step 208.

In steps 201 to 202, the first terminal requests barcode information from the server through its own identity information. For example, the first terminal sends the identity information of the first terminal to the server; and after receiving the identity information of the first terminal, the server sends the bar code information to the first terminal, wherein the bar code information comprises the identity information of the first terminal. After the first terminal acquires the bar code information, the second terminal acquires the bar code information by scanning the first terminal.

Namely, the barcode information of the first terminal is dynamically acquired through information interaction with the server, rather than factory-owned or locally-generated fixed information, so that the information for assisting positioning included in the barcode information is more comprehensive, for example, the barcode information includes state information and the like after the first terminal is matched with a system and upgraded, so that the position information is more accurate, meanwhile, manufacturing processes in factory shipment are reduced, and corresponding labor input is reduced.
In addition, when the first terminal carries the self-identity information to request the barcode information from the server, the server can perform authority judgment and screening on the first terminal, so that the security of data input into the server is improved, as shown in fig. 3.
In steps 206 to 207, the server obtains whether the identity information of the first terminal in the request for querying the location has a preset corresponding group, and if so, the server queries a location result corresponding to the group and sends the location result to the second terminal. That is, the first terminal is preset with a corresponding group, the group includes the first terminal, and the number of terminals in the group is not less than 1. Through the corresponding group relation, the position information of the whole group can be inquired only by acquiring one identity information, the large-range or same-type large-quantity inquiry requirements of users are met, the operation is simple, and the response speed is high.
