Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for preventing a mobile terminal from being lost according to an embodiment of the present invention. The terminal equipment provided by the embodiment of the invention can be electronic equipment with a Bluetooth function, such as a smart phone, a tablet personal computer, various portable mobile terminals and the like. It should be noted that the method of the present invention is not limited to the flow sequence shown in fig. 1 if the results are substantially the same.
As shown, the method comprises the following steps:
s10: starting a Bluetooth function of the mobile terminal and connecting a Bluetooth device;
bluetooth is a small-range wireless connection technology, and can realize convenient, quick, flexible, safe, low-cost and low-power-consumption data communication and voice communication among devices. The Bluetooth device can be a Bluetooth earphone, a Bluetooth sport bracelet or other wearable devices with Bluetooth functions. The main working range of the mobile terminal and the Bluetooth equipment is about 10 meters, and the mobile terminal and the Bluetooth equipment can be connected and communicated in a range of 100 meters by the Bluetooth technology after the radio frequency power is increased.
S11: sending information to the Bluetooth device and recording the time T1 of sending the information;
the mobile terminal sends information to the bluetooth device, which may be a fixed size picture, file, or other data, or may be an instruction. The mobile terminal sends data information with a specific size to the Bluetooth device at intervals, and the distance between the mobile terminal and the Bluetooth device is judged according to the information transmission time.
S12: receiving confirmation information returned by the Bluetooth equipment, and recording the time T2 of receiving the information;
when the Bluetooth equipment receives the specific information sent by the mobile terminal, the Bluetooth equipment returns confirmation information, the mobile terminal confirms whether the equipment is normally connected, and after the mobile terminal is confirmed to be normally connected with the Bluetooth equipment, the mobile terminal sends data information according to preset interval time.
And the mobile terminal starts timing from the data transmission, stops timing until the terminal receives the confirmation information returned by the Bluetooth equipment, calculates the time difference between the two as the total time of data transmission, and is used for judging the distance between the mobile terminal and the Bluetooth equipment.
S13: judging that the time difference between the sending time T1 and the receiving time T2 is compared with a preset threshold value;
s14: when the time difference is larger than a preset threshold value, the mobile terminal sends out an alarm;
the main working range of the Bluetooth technology is about 10 meters, the Bluetooth technology after increasing the radio frequency power can work in the range of 100 meters, so that the working quality and efficiency of the Bluetooth during transmission can be ensured, and the transmission speed of the Bluetooth is improved. When the mobile terminal and the Bluetooth device are in a successful connection state, the time required for normally sending the fixed data information is between 100ms and 500ms, and when the data sending time exceeds 500ms, the mobile phone loss can be judged, and the preset threshold value can be any value between 100 and 500.
Optionally, the preset threshold may include a first threshold and a second threshold, and the first threshold is smaller than or equal to the second threshold.
And when the time difference is larger than the first threshold value, the mobile terminal plays preset music for warning.
In different application scenes, music can be preset and played, and the music can be audio stored in advance or a segment of audio recorded and played in advance. The audio file can be played on the mobile terminal or simultaneously played on the Bluetooth equipment.
Optionally, when the time difference is greater than the second threshold, the terminal positioning function is started to determine the terminal position, and/or the terminal photographing function is started and the current photo or video is photographed for warning.
The user can set 2 time threshold values, when the transmission time difference is greater than a preset first threshold value and the distance between the mobile terminal and the Bluetooth device is controllable, the playing function is started to play music, when the transmission time difference is greater than a preset second threshold value, the distance between the mobile terminal and the Bluetooth device is far, the GPS positioning can be started, or the terminal photographing function is started to photograph the current picture or record the current video. In different application scenes, a user can also set the functions of simultaneously starting music playing, GPS positioning and mute photographing, and quickly retrieve the mobile phone.
Optionally, when the time difference is greater than the second threshold, the mobile terminal sends the acquired positioning information and the shot picture or video to a preset associated terminal and/or a preset cloud.
When the time difference is greater than the preset second threshold, the mobile terminal GPS positioning information or the information such as the current shot picture/video and the like can be sent to another terminal device of the pre-equipment or uploaded to a cloud server, so that a user can conveniently obtain the information and find the terminal device.
Optionally, when the time difference is greater than the second threshold, the terminal shutdown function is disabled.
When the mobile terminal is far away from the Bluetooth equipment, in order to prevent a third person from shutting down, the shutdown function of the terminal can be forbidden, or temporary current is provided for the mobile terminal, so that the normal work of basic functions is ensured.
S15: when the time difference is less than or equal to the preset threshold, execution continues to step S11.
In this embodiment, when the mobile terminal successfully connects to the bluetooth device and sends a picture, a file or other data with a fixed size to the bluetooth device for the first time, when the sending time exceeds a preset threshold, the mobile terminal does not receive the confirmation information returned by the bluetooth device, and sends a notice that the bluetooth device is not successfully connected or directly sends a warning information; when the data packet is sent for the first time, after receiving the confirmation information returned by the bluetooth device within the preset time, the mobile terminal may send data to the bluetooth device at regular time according to the previously set interval time.
It should be noted that this embodiment is only one application scenario of the invention, and in other embodiments, the alarm mode may also be a combination of other modes, such as flashing light for reminding, playing music or dialing a fixed-line telephone, and the like.
Through the mode, the mobile terminal sends information to the Bluetooth device periodically, and when the mobile terminal leaves the Bluetooth device to reach a certain distance, the mobile terminal provides a warning function to remind a user and prevent the mobile terminal from being lost.
