In this embodiment, a terminal is taken as an example of a wearable device, and a detailed description of the scheme is performed, and other situations are similar to the above, and are not described again in this embodiment.
Before implementation, a guardian (hereinafter, may be referred to as a user a) may install a management application in a management terminal for managing wearable devices used by a monitored person (hereinafter, may be referred to as a user B), the user a may open the management application installed on the management terminal, the management terminal may display a login interface of the management application, the user a may input a login account and a login password, then click a confirmation key, trigger the management terminal to display a main interface of the management application, and the main interface displays bound devices, addition options, and some other options. The user A can click the addition option to trigger the management terminal to search nearby devices through the Bluetooth function, the management terminal can display and search all the devices in the interface, the user A can click the selection option corresponding to the wearable device to be bound, and after receiving the click instruction, the management terminal sends a binding request to the wearable device through a background server (which can be referred to as a server for short in the following process) of the management application program. After the wearable device receives the binding request, the binding request can be displayed, the confirmation option is displayed corresponding to the binding request, the user B can click the confirmation option, after the wearable device receives a click command of the confirmation option, the binding confirmation message can be sent to the management terminal through the server, the server records that the management terminal is the binding terminal of the wearable device, and therefore the binding relationship between the management terminal and the wearable device is established.
As shown in fig. 1, the processing flow of the method may include the following steps:
and 101, detecting the cell information of the position point of the terminal based on the LBS.
The cell information may include the cell number and the cell signal strength of the cell detected to be accessed at the location point, the cell number and the cell signal strength of the cell adjacent to the accessed cell, the distance between the base station to which the accessed cell belongs and the location point, and the like.
In the implementation, the wearable device can be worn on user B's body, such as smart watch, smart bracelet, can be worn on user's wrist. After the wearable device is started, LBS can be used for periodically detecting cell information of a position point where the terminal is located, or the LBS is used for detecting the cell information of the position point where the terminal is located every time the preset step number is moved, the period mentioned here can be preset by technical personnel, the preset step number can also be preset by the technical personnel, and the preset step number is stored in the wearable device.
It should be noted that, the above-mentioned cell information of the location point where the terminal is located detected by using LBS may be the cell information of the location point where the terminal is located obtained by receiving the system information sent by the base station.
The electronic fence area may be set on the management terminal by the user a, and may be a region through which the user a inputs a latitude and longitude range in a setting interface of the electronic fence area of the management terminal, and sends the latitude and longitude range to the wearable device through the server, and the wearable device stores the latitude and longitude range, for example, as shown in fig. 2(a), the user B is a pupil, and the electronic fence area may be an area through which the user B passes from home to school. The preset boundary may be a boundary inside the fence area and a preset distance from the fence area boundary, or may be a boundary set by the user a, for example, as shown in fig. 2(b), the preset boundary is a boundary 2 meters away from the fence area boundary, and the like.
In implementation, the wearable device stores, in advance, cell information corresponding to each location point on a preset boundary inside the electronic fence area, where each location point may be a location point every 50 centimeters or the like on the preset boundary, and a method for presetting the cell information corresponding to each location point on the preset boundary is described in detail later.
When the wearable device determines that the wearable device moves to the preset boundary according to the currently detected cell information and the cell information corresponding to each position point on the preset boundary, the wearable device starts GPS position monitoring processing and detects the current position information by using a GPS.
It should be noted that when GPS positioning is generally used, satellite parameters and ephemeris are acquired, and the satellite parameters and ephemeris are generally deleted after 2 hours from GPS being turned off. If the distance between the current time point and the last time point of using the GPS is less than 2 hours, the GPS is started to be hot-started, satellite parameters, ephemeris and the like are stored in the wearable device, the satellite parameters and the ephemeris do not need to be acquired again, and therefore 10 seconds are generally needed from the start of the GPS to the normal work of the GPS. If the distance between the current time point and the time point of using the GPS last time is more than or equal to 2 hours, the GPS is started to be cold start, the satellite parameters and the ephemeris in the wearable device are deleted, the satellite parameters and the ephemeris need to be obtained again, and therefore 1 minute is generally needed from the start of the GPS to the normal work of the GPS. In the embodiment of the invention, the preset boundary is in the electronic fence area, and as long as the wearable device moves to the preset boundary, the GPS position monitoring processing is started, so that the wearable device can be prevented from exceeding the electronic fence area, starting the GPS for position monitoring processing, and losing the position information of the wearable device.
Optionally, the cell information includes a cell number and a cell signal strength of each cell, and the corresponding processing in step 102 may be as follows:
and when the cell number of each currently detected cell is the same as the cell number of each cell detected by the first position point in each position point, and the difference between the cell signal strengths of the cells with the same number is smaller than a first preset value, starting the GPS position monitoring processing.
Each cell is a cell which can be detected by the wearable device at the location point, and generally includes a cell accessed by the wearable device and a cell adjacent to the accessed cell. The cell information includes the cell number and the cell signal strength of each cell, and a first preset numerical value can be preset by a technician and stored in the wearable device.
In implementation, after the wearable device moves to a location point, it is determined whether the cell number of each detected cell is the same as the cell number of each cell detected by any one of the location points recorded in advance, and if so, it is continuously determined whether the differences between the cell signal strengths of the cells with the same number are all smaller than a first preset value. When the cell number of each currently detected cell is the same as the number of each cell detected by the first position point in each position point at a certain position point, and the difference between the cell signal intensities of the cells with the same number is smaller than a first preset value, the wearable device can determine that the wearable device moves to a preset boundary at the moment, and then can control to start GPS position monitoring processing and detect position information by using a GPS.
For example, the first preset value is 5dBm, the cell numbers of the currently detected cells are 25, 30 and 28, the cell signal strengths are-65 dBm, -70dBm and-72 dBm, respectively, the cell numbers of the cells detected at the first location point are 25, 30 and 28, the cell signal strengths are-62 dBm, -73dBm and-68 dBm, respectively, and the differences between the cell signal strengths of the cells with the same number are 3dBm, 3dBm and 4dBm, respectively, which are all less than 5dBm, so that the wearable device can determine that the wearable device moves to the preset boundary at the moment, and the wearable device can control to start the GPS location monitoring process and detect the location information by using the GPS.
Optionally, the cell information includes a cell number and a cell signal strength of a cell to which the terminal is accessed, and a distance between the terminal and a base station to which the accessed cell belongs; the corresponding processing of step 102 may be as follows:
and when the cell number of the cell accessed by the terminal detected currently is the same as the cell number of the cell accessed by the terminal detected by the second position point in each position point, the difference between the first distance and the second distance is smaller than a second preset value, and the difference between the signal intensity of the first cell and the signal intensity of the second cell is smaller than a third preset value, starting GPS position monitoring processing.
The second preset value and the third preset value can be preset by a technician and stored in the wearable device, the third preset value can be the same as the first preset value mentioned above, the first distance is the distance between the currently detected terminal and the base station to which the accessed cell belongs, the second distance is the distance between the terminal detected by the second location point and the base station to which the accessed cell belongs, the signal intensity of the first cell is the signal intensity of the currently detected cell to which the accessed cell belongs, and the signal intensity of the second cell is the signal intensity of the accessed cell detected by the second location point.
In implementation, after the wearable device moves to a location point, it is determined whether a cell number of an accessed cell is the same as a cell number of a cell accessed by any one of the location points recorded in advance, if so, a difference between the first distance and the second distance is continuously determined, if the difference is smaller than a second preset value, a difference between the signal intensity of the first cell and the signal intensity of the second cell is continuously determined, and if the difference is smaller than a third preset value, it may be determined that the wearable device moves to a preset boundary. When the wearable device is located at a certain position point, the cell number of the cell accessed by the currently detected wearable device is the same as the cell number of the cell accessed by the second position point, the difference between the first distance and the second distance is smaller than a second preset value, the difference between the signal intensity of the first cell and the signal intensity of the second cell is smaller than a third preset value, the wearable device determines that the wearable device moves to a preset boundary, then the wearable device can control to start GPS position monitoring processing, and the GPS is used for detecting position information.
For example, the second preset value is 5 meters, the third preset value is 5dBm, the cell number of the currently detected cell to which the wearable device is connected is 1, the cell number of the cell to which the wearable device is connected, detected at the second location point, is 1, the first distance is 100 meters, the second distance is 96 meters, the signal intensity of the first cell is-60 dBm, the signal intensity of the second cell is-56 dBm, the difference between the first distance and the second distance is less than 5 meters, the difference between the signal intensity of the first cell and the signal intensity of the second cell is less than 5dBm, the wearable device determines that the wearable device moves to a preset boundary, and then can control to start the GPS position monitoring process and detect the position information using the GPS.
Optionally, the LBS is any one of single base station location, seventh instruction location, electric wave transmission time location, incident angle location, and field strength location.
In implementation, the single base station positioning is to determine the position of the wearable device according to the position of the base station to which the currently accessed cell belongs.
And the seventh instruction positioning is to analyze a signaling process between the wearable device and a base station to which the accessed cell belongs to obtain the distance between the wearable device and the base station.
The positioning of the electric wave transmission time is to obtain the distance between the wearable device and the base station based on the transmission time length and the transmission speed of the electric wave transmitted to the wearable device by the base station to which the accessed cell belongs.
The incident angle positioning is also based on the transmission duration, the transmission speed and the emission angle of the radio wave sent to the wearable device by the base station to which the accessed cell belongs, so as to obtain the distance between the wearable device and the base station.
And field intensity positioning, namely obtaining the distance between the wearable equipment and the base station through the received field intensity of the signal transmitted by the base station to which the accessed cell belongs.
The above-mentioned positioning methods are all commonly used positioning methods in the prior art, and are the same as the positioning process in the prior art.
And 103, when the terminal is determined to move to the inside of the preset boundary and move towards the direction far away from the preset boundary according to the position information detected by the GPS, the GPS position monitoring processing is closed, and the cell information of the position point where the terminal is located is continuously detected based on the LBS.
In implementation, the wearable device can detect the position information of the current position point based on the GPS, and the position information can be expressed by latitude and longitude. When the wearable device determines that the current position point is within the preset boundary according to the range information of the preset boundary and the position information detected by the current position point, and the direction of the previous position pointing to the current position point is the direction far away from the preset boundary, the wearable device determines that the wearable device moves into the preset boundary and moves towards the direction far away from the preset boundary, the wearable device can close the GPS position monitoring processing, and then the LBS is continuously used for detecting the cell information of the position point of the wearable device.
Optionally, the cell information includes a cell number of each cell, and the wearable device may start the GPS location monitoring process when encountering the following conditions in the process of using the LBS to detect the cell information of the location point where the wearable device is located, where the corresponding process may be as follows:
and when any cell number in the cell numbers of the currently detected cells is not in the cell numbers of the cells detected by the position points in the pre-recorded electronic fence area, starting GPS position monitoring processing.
The cell information includes a cell number of each cell, and generally includes a cell number of a cell accessed at a location point and a cell number of a cell adjacent to the accessed cell.
In an implementation, the wearable device stores in advance the cell numbers of the respective cells detected at the respective location points in the electric fence area (the process of storing the cell numbers of the respective cells detected at the respective location points will be described in detail later).
After the wearable device moves to a position point, the cell numbers of all cells detected by the current position point can be detected, and then the cell numbers are compared with the cell numbers of all cells detected by the pre-recorded position points.
In addition, if the position information detected by the GPS is used to determine that the current position point of the wearable device is in the electronic fence area, the corresponding relationship between the position point information of the current position point and the detected cell information of each cell may be stored. If the position information detected by the GPS is used, the wearable device is determined that the current position point of the wearable device is not in the electronic fence area, and the wearable device can send a cross-fence notification to the server. When receiving the notice of crossing the fence sent by the wearable device, the server searches for a terminal, namely a management terminal, which is in a binding relationship with the wearable device, and then sends the notice of crossing the fence to the management terminal.
In the embodiment of the present invention, a method for sending a notification of crossing a fence to a management terminal by a wearable device is further provided, and corresponding processing may be as follows:
and when the terminal is determined to be out of the electronic fence area according to the position information detected by the GPS and the range information of the electronic fence area, sending a fence crossing notification to the terminal which is in binding relationship with the terminal.
The range information of the electronic fence area may be latitude and longitude range information of a boundary of the electronic fence area.
In implementation, after the wearable device starts the GPS location monitoring process, it may detect latitude and longitude information of a current location point, and if the latitude and longitude information is not within the range information of the electronic fence area, the wearable device determines that the wearable device is outside the electronic fence area, and the wearable device may send a fence crossing notification to the server. When receiving the notice of crossing the fence sent by the wearable device, the server searches for a terminal, namely a management terminal, which is in a binding relationship with the wearable device, and then sends the notice of crossing the fence to the management terminal. When the management terminal receives the crossing fence notification sent by the server, the crossing fence notification can be displayed, and when the crossing fence notification is displayed, a preset prompting sound is played, wherein the preset prompting sound can be preset by a technician and is stored in the wearable device.
For example, as shown in fig. 3, the electronic fence area is rectangular, the electronic fence area range information is 50 degrees to 52 degrees of east longitude and 35 degrees to 37 degrees of north latitude, the position information of the current position point is 52.1 degrees of east longitude and 34.9 degrees of north latitude, and the current position point is outside the electronic fence area, and the wearable device may send a fence crossing notification to the terminal having a binding relationship with the wearable device.
In addition, when the position point of the wearable device is outside the electronic fence area, the wearable device can send the real-time position information detected by the GPS to the management terminal.
In addition, when the wearable device detects that the wearable device returns to the preset boundary and moves away from the preset boundary, a return fence notification can be sent to the management terminal.
In the embodiment of the present invention, a method for determining cell information corresponding to each location point on a preset boundary and a cell number of a cell detected by each location point in an electronic fence area is further provided, and corresponding processing may be as follows:
after the user A sets the electronic fence area, the range information of the electronic fence area can be sent to the server, and the server sends the range information of the electronic fence area to the wearable device. After the wearable device receives the range information of the electronic fence area, GPS position monitoring management can be started, the position information is detected in real time every preset time, and meanwhile LBS is used for detecting the cell information of the position point. If a certain location point belongs to location points in the fence area, the location point is stored in correspondence with cell information detected using LBS. When the percentage of the maximum outline composed of the stored location points in the electronic fence area is greater than a certain value, the GPS location monitoring management is turned off, and then step 101 can be executed. Therefore, the wearable device stores the corresponding relation between the position information of each position point and the corresponding cell information, and also stores the cell number of the cell detected by each position point in the electronic fence area.
The wearable device determines the position points on the preset boundary in the position points, so that the cell information corresponding to the position points on the preset boundary is determined.
In addition, when the number of stored location points is not increased for N days, the GPS location monitoring management may also be turned off, and step 101 may be performed subsequently.
In addition, in the above mentioned process, the wearable device itself determines the cell information corresponding to each location point on the preset boundary and the cell number of the cell detected by each location point in the electronic fence area, and similarly, the user a may also use its own management terminal, and start the GPS location monitoring management and LBS for determination at the same time, and the determination method is the same as the foregoing, and is not described herein again. After the management terminal determines cell information corresponding to each position point on the preset boundary and cell numbers of cells detected by each position point in the electronic fence area, the information can be sent to the server, the server can search wearable equipment which is in binding relation with the management terminal after receiving the information sent by the management terminal, then the information is sent to the wearable equipment, and the wearable equipment can store the information after receiving the information. If a plurality of wearable devices are arranged, the server sends the identification of the wearable devices to the management terminal when sending the notice of crossing the fence to the management terminal.
In addition, the execution main body of the above embodiment is a wearable device, and may also be a server, and after the wearable device detects cell information of a location point where the terminal is located, the wearable device sends the cell information to the server, and the server determines whether to start the GPS location monitoring processing. And when the server determines that the position point of the wearable device is out of the electronic fence area, sending a cross-fence notification to the management terminal.
In the embodiment of the invention, the cell information of the position point of the terminal is detected based on LBS, when the terminal is determined to move to the preset boundary according to the currently detected cell information and the pre-recorded cell information corresponding to each position point on the preset boundary in the electronic fence area, GPS position monitoring processing is started, when the terminal is determined to move to the preset boundary and move towards the direction far away from the preset boundary according to the position information detected by the GPS, the GPS position monitoring processing is closed, and the cell information of the position point of the terminal is continuously detected based on LBS. Therefore, the GPS can be started only when the terminal moves to the preset boundary, and cannot be started all the time, so that the power consumption of the terminal can be saved.
