The purpose of the disclosure is to improve the security of a positioning terminal and prevent information leakage which may be caused by the positioning terminal.
The embodiment of the disclosure provides a positioning terminal and a control method. The positioning terminal can be a satellite positioning terminal, such as a high-precision positioning terminal supporting a Beidou positioning system. The positioning terminal supports two or more working modes, including a stand-alone positioning working mode and a group positioning working mode. Under the single machine positioning working mode, the positioning terminal can acquire the position information of the machine. In the group positioning mode, the positioning terminal can obtain the position information of the local and the position information of other positioning terminals in the group. The common user can use the stand-alone positioning working mode, the authorized user can use the group positioning working mode, and the unauthorized user is prevented from acquiring the position information of other positioning terminals in the group, so that the safety of the positioning terminal is improved, and the positioning terminal is prevented from being illegally used.
The embodiment of the disclosure provides a positioning terminal control method, which is applied to a positioning terminal. As shown in fig. 1, the positioning terminal control method includes the following steps:
101. and when a mode switching instruction is received in the single machine positioning working mode, the identity identification information of the user is acquired.
In one embodiment, the default operating mode when the positioning terminal is powered on is a stand-alone positioning operating mode.
Under the single machine positioning working mode, the positioning terminal can send the position information of the machine to the server, and the server records and monitors the position change of the positioning terminal. The optional server can display the position change process of the positioning terminal through the display device of the position monitoring platform.
The positioning terminal may be provided with a function key for triggering the mode switching instruction, and the positioning terminal receives the mode switching instruction when a user presses the function key.
Referring to the display interface shown in fig. 2, when the positioning terminal receives the mode switching instruction, the positioning terminal may request the user to input the identification information. The identification information may include a username and password, among other information.
102. And sending the identity identification information to a server.
After the user inputs the identity identification information, the positioning terminal sends the identity identification information to the server. For example, the positioning terminal may encrypt the identification information by using an encryption algorithm and send the encrypted identification information to the server. The server decrypts the identity identification information to obtain the identity identification information, verifies the identity identification information and determines the identity identification information as the identity identification information of an authorized user or the identity identification information of an unauthorized user.
103. And receiving authorization indication information sent by the server.
And when the server determines that the identity identification information input by the user is the identity identification information of the authorized user, the server sends authorization indication information to the positioning terminal. The authorization indication information is used for indicating that the identification information input by the user is identification information of an authorized user.
104. And switching from the single machine positioning working mode to the group positioning working mode.
And when the positioning terminal receives the authorization indication information, switching from the single machine positioning working mode to the group positioning working mode.
In the group positioning mode, the positioning terminal can obtain the position information of the local and the position information of other positioning terminals in the group.
The positioning terminals in the group can be managed by the server. For example, the server receives an indication of a location monitoring platform and divides a plurality of positioning terminals into a group. And the server receives the position information reported by each positioning terminal in the group and shares the position information of all the positioning terminals in the group to each positioning terminal in the group.
When the positioning terminal is in the group positioning working mode, the user can check the position information of all the positioning terminals in the group.
In the method for controlling a positioning terminal provided by the embodiment of the present disclosure, the working modes of the positioning terminal include a stand-alone positioning working mode and a group positioning working mode. Under the single machine positioning working mode, the positioning terminal can acquire the position information of the machine. In the group positioning mode, the positioning terminal can obtain the position information of the local and the position information of other positioning terminals in the group. When the positioning terminal receives the mode switching instruction in the stand-alone positioning working mode, the positioning terminal triggers a user identity authentication process to acquire the identity identification information of the user and requests the server to authenticate the identity identification information. And when receiving the authorization indication information returned by the server, switching from the stand-alone positioning working mode to the group positioning working mode.

Based on the positioning terminal control method provided by the embodiments corresponding to fig. 1-fig. 2, another embodiment of the present disclosure provides a further supplementary description on the positioning terminal control method. The content of some steps is the same as or similar to the steps in the corresponding embodiment of fig. 1, and only the differences in the steps will be described in detail below.
Referring to fig. 3, the positioning terminal control method provided in this embodiment includes the following steps:
301. and when a mode switching instruction is received in the single machine positioning working mode, the identity identification information of the user is acquired.
In one embodiment, the server may send a mode switch instruction to the positioning terminal. And when the positioning terminal receives a mode switching instruction sent by the server, the positioning terminal requests the user to input identity identification information.
302. And sending the identity identification information to a server.
After the user inputs the identity identification information, the positioning terminal sends the identity identification information to the server. The server verifies the identity identification information and determines that the identity identification information is the identity identification information of an authorized user or the identity identification information of an unauthorized user.
And when the identity identification information of the authorized user is determined, the authorization indication information is sent to the positioning terminal.
303. And receiving authorization indication information sent by the server.
The authorization indication information is used for indicating that the identity identification information reported by the positioning terminal is the identity identification information of the authorized user.
304. And switching from the single machine positioning working mode to the group positioning working mode.
And when the positioning terminal receives the authorization indication information, switching from the single machine positioning working mode to the group positioning working mode.
In the group positioning mode, the positioning terminal may respond to certain special instructions. For convenience of explanation, these instructions are referred to as a risk avoidance instruction, a channel selection instruction, and an environmental parameter acquisition instruction.
The positioning terminal may or may not respond to these instructions in the stand-alone positioning mode of operation.
305. And receiving a risk avoiding instruction in a group positioning working mode.
The risk avoiding instruction can be triggered by a user through a function key of the positioning terminal. The positioning terminal can also receive the risk avoiding instruction sent by the server.
For example, when a user of the positioning terminal encounters an emergency, the functional key is operated to trigger a risk avoidance instruction, and the positioning terminal responds to the risk avoidance instruction and sends alarm information to the server, wherein the alarm information includes current position information.
And after receiving the alarm information, the server outputs the alarm information through the display equipment of the position monitoring platform. For example, displaying the location information of the positioning terminal, triggering an alarm bell, etc.
In one embodiment, the positioning terminal responds to the risk avoidance instruction and clears the locally stored data information to prevent the information of the positioning terminal from being leaked.
In one embodiment, the positioning terminal cuts off the communication channel in response to the risk avoidance instruction. After the communication channel is cut off, the communication function of the positioning terminal is invalid, thereby preventing an illegal user from using the positioning terminal to receive any information sent by the server or other positioning terminals in the group. Or actively send any information to the server and other positioning terminals in the group.
306. A communication channel selection instruction is received in a group positioning mode of operation.
The communication channel selection instruction may be triggered by the user through a function key of the location terminal. The positioning terminal can also receive a communication channel selection instruction sent by the server.
The positioning terminal may support multiple communication channels. And when receiving the communication channel selection instruction, the positioning terminal enables the selected communication channel to carry out wireless communication in response to the communication channel selection instruction.
The selected communication channel comprises any one of a radio ad hoc network communication channel, a satellite communication channel, a wireless internet communication channel and a wireless local area network communication channel.
In the group positioning working mode, the positioning terminal responds to the communication channel selection instruction, selects a specific communication channel for wireless communication, and can select other communication channels for wireless communication when one communication channel cannot work normally.
307. And receiving an environmental parameter acquisition instruction in a group positioning working mode.
The environmental parameter acquisition instruction can be triggered by a user through a function key of the positioning terminal. The positioning terminal can also receive an environmental parameter acquisition instruction sent by the server.
The positioning terminal comprises a parameter acquisition module, and the parameter acquisition module comprises any one of a temperature sensor, a humidity sensor, a light sensor and a camera.
When receiving the environmental parameter acquisition instruction, the positioning terminal responds to the environmental parameter acquisition instruction, starts the parameter acquisition module to acquire the environmental parameters of the current environment and sends the acquired environmental parameters to the server. The environmental parameter may be any information collected by the parameter collection module, such as temperature, humidity, information collected by the light sensor, a photo or video collected by the camera, and the like.
In the group positioning working mode, the positioning terminal responds to the environmental parameter acquisition instruction, acquires the environmental parameters and reports the environmental parameters to the server, so that the server can record and analyze the relevant information of the environment where the positioning terminal is located. The server can send instructions such as risk avoiding instructions, channel selection instructions and the like to the positioning terminal according to the analysis result.
308. And under the group positioning working mode, the identity identification information of the user is obtained again.
And under the group positioning working mode, when a preset trigger condition is met, the identity identification information of the user is obtained again.
In one embodiment, when the positioning terminal determines that the positioning terminal is located beyond the coverage area of the electronic fence, the positioning terminal requests the user to input the identification information again. The electronic fence can be set and updated by the server.
In one embodiment, when the positioning terminal determines that the moving speed of the positioning terminal exceeds the preset speed range, the positioning terminal requests the user to input the identification information again.
For example, the preset speed range is represented as [ a, b ], and when the moving speed of the positioning terminal is less than a or greater than b, the user is requested to input the identification information again.
In one embodiment, when the positioning terminal determines that the variation range value of the position of the positioning terminal within the preset time length does not exceed the preset range value, the positioning terminal requests the user to input the identity information again.
Two points which are farthest away from each other on the motion trail of the positioning terminal in a period of time can be used as parameters for measuring the position change range of the positioning terminal. This parameter was taken as R. The larger the R value is, the larger the value of the range of position variation of the positioning terminal in the period is. The smaller the R value is, the smaller the value of the position change range of the terminal equipment in the period is.
When the positioning terminal is within a preset time (for example, 10 minutes) and the corresponding R value is smaller than a preset range value (for example, 5 meters), the positioning terminal requests the user to input the identification information again.
After the positioning terminal determines that the user inputs the identity identification information, the positioning terminal jumps to step 302, and triggers the user identity authentication process again, so that the safety of the positioning terminal is further improved, and the positioning terminal is prevented from being illegally used.
Referring to fig. 3, there is no sequence among step 305, step 306, step 307, and step 308.
In the method for controlling a positioning terminal provided by the embodiment of the present disclosure, the working modes of the positioning terminal include a stand-alone positioning working mode and a group positioning working mode. Under the single machine positioning working mode, the positioning terminal can acquire the position information of the machine.
