Detailed Description
In order to provide an implementation scheme for avoiding loss caused by the loss of a mobile terminal by a user, embodiments of the present invention provide a method, an apparatus, and a system for preventing the loss of a mobile terminal, and the following description is made with reference to the accompanying drawings. And the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The embodiment of the invention provides a method for preventing a mobile terminal from being lost, which is applied to wearable equipment, and the flow chart is shown in figure 1 and comprises the following steps:
step 101, sending a wireless connection request to the mobile terminal for establishing wireless connection with the mobile terminal.
The wireless connection mode may be various, such as bluetooth, infrared, etc., and bluetooth connection is preferred in this embodiment, but not limited thereto. In the embodiment of the invention, the mobile terminal starts the Bluetooth connection by default.
And 102, if the wireless connection is failed to be established, sending a prompt to a user.
At this time, there are two situations, one is that the mobile terminal of the user is powered off due to insufficient electric quantity, and the other is that the mobile terminal of the user is lost, and a prompt is sent to the user in time to search the position of the mobile terminal, so as to reduce unnecessary loss.
And 103, if the wireless connection is successfully established, determining the signal intensity of the wireless connection and the current signal detection gear when signal detection is required.
The signal detection gear is arranged on the wearable device and used for representing the current wireless connection environment and switching gears according to different wireless connection environments.
And 104, when the signal intensity of the wireless connection is smaller than a preset threshold corresponding to the current signal detection gear, reminding a user that the mobile terminal exceeds a safety range.
According to the method provided by the embodiment of the invention, the wireless connection is established with the mobile terminal, and when the signal intensity of the wireless connection is smaller than the preset threshold value, the prompt is sent to the user, so that the user can timely find that the mobile terminal is not around, the loss of the mobile terminal can be timely prevented, or the inconvenience caused by forgetting to take the mobile terminal by the user is avoided; furthermore, because different wireless connection environments affect the signal strength, when the indoor wall blocks or the number of signal sources is large, the interference is obvious, and thus, although the distance between the mobile terminal and a user is very short, the signal strength is low possibly due to the interference of the signal, so that the false reminding is caused.
The method and apparatus and corresponding system provided by the present invention are described in detail below with reference to the accompanying drawings using specific embodiments. Mainly for the case of successful establishment of wireless connection, a specific method flowchart is shown in fig. 2, and includes:
step 201, establishing wireless connection between the wearable device and the mobile terminal.
Wherein, wearing class equipment in this embodiment has carried mobile terminal and has prevented losing the device, and wearing class equipment can be wrist-watch, bracelet, necklace etc. and mobile terminal is like cell-phone, PAD etc.. The wireless connection mode may be various, such as bluetooth, infrared, etc., and bluetooth connection is preferred in this embodiment, but not limited thereto.
Step 202, determining that signal detection is required.
In this step, the determination that signal detection is required may be performed by:
in the first mode, a certain detection period is preset, and when the detection period arrives, the signal detection is determined to be required;
in the second mode, the user can directly input a signal detection instruction to the wearable device, and when the wearable device receives the signal detection instruction input by the user, the signal detection is determined to be needed.
Step 203, determining the signal strength of the wireless connection and the current signal detection gear. The signal detection gear is arranged on the wearable device and used for representing the current wireless connection environment and switching gears according to different wireless connection environments.
Because the signal environments of the indoor environment and the outdoor environment are different, multiple walls in the room are generally isolated to influence signal transmission, and the isolation in the outdoor environment is less, so that the signal transmission is better; the number of surrounding signal sources can also influence the signal strength, so that if the distance of the mobile terminal is judged only according to the signal strength, the judged distance is not accurate enough due to the factors of signal propagation environments.
The signal detection gear can comprise a first signal detection gear and a second signal detection gear, wherein the first signal detection gear is set when the number of the detected signal sources is less than the number of the preset signal sources, and the second signal detection gear is set when the number of the detected signal sources is not less than the number of the preset signal sources; alternatively, the first signal detection range is set when the vehicle is in an outdoor environment, and the second signal detection range is set when the vehicle is in an indoor environment. Further, the signal detection gear can be divided into a plurality of gears, and can be specifically set according to needs.
The switching of the signal detection gear can be automatically performed by the system according to the detected signal source, or can be performed by a user according to the wireless connection environment, and the switching can be flexibly set according to actual needs.
Specifically, the determination of the signal strength may adopt a measurement method in the prior art to determine a specific dBm value, and the measurement method is not described herein again.
And step 204, displaying the signal intensity on a wearable device screen.
And step 205, when the signal intensity of the wireless connection is smaller than a preset threshold corresponding to the current signal detection gear, sending a prompt to a user to indicate that the mobile terminal exceeds a safety range.
Furthermore, a certain time can be preset, and when the detected signal intensity of the wireless connection in the preset time is smaller than the preset threshold corresponding to the current signal detection gear, the user is reminded.
Different signal detection gears correspond to different preset thresholds, and the preset time and the signal intensity threshold can be set by a user. If a fixed detection period is preset, when the number of times of continuously detecting that the signal intensity is smaller than a preset threshold corresponding to the current signal detection gear exceeds a preset number of times, a prompt can be sent to a user. The wearable device may also be used in various ways, such as an audio alarm, a vibration motor, an LED lamp, etc., as long as the wearable device is easily found by the user and attracts the attention of the user.
Step 206, determining the distance between the mobile terminal and the user according to the signal strength of the wireless connection and the current signal detection gear.
Wherein the distance is determined according to the signal strength, a determination method in the prior art can be adopted, and is not described in detail herein.
The distance between the mobile terminal and the user determined in the step can be displayed on the wearable device, and the range of the mobile terminal can be more intuitively represented. Specifically, a set of LED indicator lamps and a corresponding distance scale can be arranged on one side of the wearable device, and the corresponding relation between the LED indicator lamps and the distance can be represented through the LED lamp set.
And step 207, determining the position of the mobile terminal by the user through the signal intensity displayed on the wearable device and the distance represented by the LED lamp group.
The user can check the displayed signal intensity and the distance between the mobile terminal and the user in real time in the process of searching the mobile terminal, so that the searching is more convenient and quicker.
