Background

Wearable devices (e.g., sports watches) with mountain climbing modes are often expensive, and can record GPS information, altitude, barometric pressure values, etc. when a user climbs a mountain.

The communication module 190 may establish a direct (or wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108), or may perform communication through the established communication channel. The communication module 190 may include one or more communication processors that operate independently of the processor 120 (e.g., an application processor) and support direct (or wired) or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a Global Navigation Satellite System (GNSS) communication module) or a wired communication module 194 (e.g., a Local Area Network (LAN) communication module or a power line communication module).

Communication modules of the kind described above may be integrated in one component (e.g., a single chip) or may be implemented with multiple components (e.g., multiple chips) that are independent of each other. The wireless communication module 192 may verify and authenticate the electronic device 101 within a communication network, such as the first network 198 or the second network 199, by using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

According to embodiments, all or a portion of the operations to be performed in the electronic device 101 may be performed in one or more of the external electronic devices 102, 104, or 108. For example, in the case where the electronic device 101 should automatically perform any function or service or perform any function or service in response to a request from a user or any other device, the electronic device 101 may request one or more external electronic devices to perform at least a portion of the function or service, rather than performing the function or service internally or otherwise. The one or more external electronic devices that received the request may perform at least a portion of the functions or services so requested or additional functions or services associated with the request, and may provide the results of the execution to the electronic device 101. The electronic device 101 may process the received results as is or otherwise, and may provide the processed results as at least a portion of the response to the request. To this end, for example, cloud computing, distributed computing, or client-server computing techniques may be used.

In step 201, environmental information including time information and altitude information is acquired at specific intervals in response to the initiation of a predetermined mode.

In this embodiment, the user may turn on a predetermined mode (e.g., a mountain climbing mode) of the mobile terminal (e.g., a smart phone), which may be implemented by a mobile phone application, but is not limited thereto. After the mountain climbing mode is turned on, the terminal application records environmental information, such as a local terminal time, an air pressure value, or an altitude value, once every certain time (e.g., one minute). Optionally, the terminal application also records longitude and latitude and communication information once every specific time (e.g., one minute). Here, the communication information may include, for example: a currently camping Cell identification code (Cell ID), a Received Signal Strength (RSSI) of a base station downlink reference signal, and an angle of arrival (AOA) of the base station downlink reference signal. Alternatively, when the user is in a predetermined mode (e.g., a mountain climbing mode) and no falling occurs, the user can check his or her own movement track by determining his or her own movement track through time, altitude, GPS and communication information recorded at every specific time.

The information can be stored in real time for users to view at any time. In addition, the above information is acquired independently of each other, and for example, when GPS is not available at a certain time, other information can still be recorded normally.

In step 202, when a fall is determined to occur based on the acceleration detected by the acceleration detector, first environmental information is acquired, wherein the first environmental information includes first time information and first altitude information.

In this embodiment, after the mountain climbing mode is turned on, when the user performs free falling movement or is in a weightless state (i.e., the acceleration in the vertical direction detected by the acceleration sensor is not 0), the falling start is determined, the time at this time is recorded as a first time (T1), and the height at this time is a first height (H1).

Optionally, acquiring the first environmental information further includes: when it is determined that a fall occurs based on the acceleration detected by the acceleration detector, first latitude and longitude information (GPS 1) and first communication information (Cell id_1, rssi_1, and aoa_1) are acquired.

At step 203, when it is determined that the fall is over based on the acceleration detected by the acceleration detector, second environmental information is acquired, wherein the second environmental information includes second time information and second altitude information.

In the present embodiment, when the acceleration in the vertical direction of the user detected by the acceleration detector is 0, the end of the fall is judged, and the time at this time is recorded as the second time (T2), and the height at this time is the second height (H2).

Optionally, acquiring the second environmental information further includes: when the end of the fall is determined based on the acceleration detected by the acceleration detector, second latitude and longitude information (GPS 2) and second communication information (cellid_2, rssi_2, and aoa_2) are acquired.

In step 204, it is determined whether a normal fall or a severe fall has occurred based on the difference between the first time information and the second time information and/or the difference between the first height information and the second height information.

In this embodiment, the fall duration T can be determined from the difference between T1 and T2, as shown in equation one below.

t=t2-T1 (equation one)

When the fall duration T is less than a predetermined time (e.g., 1.5 s), the user may be considered to be actively jumping down, with a normal fall occurring; and when the fall duration T is greater than or equal to a predetermined time (e.g., 1.5 seconds), the user may be considered to have a severe fall.

In this embodiment, the drop height difference H can be determined from the difference between H1 and H2 as shown in equation two below.

h=h2-H1 (equation two)

When the drop height difference is smaller than a predetermined height (e.g., 10 m), the user can be considered to be actively jumping down, and it is determined that an ordinary drop occurs; and when the drop height difference is greater than or equal to a predetermined height (e.g., 10 meters), determining that a severe drop has occurred.

In the present embodiment, as shown in the following equation three, the fall acceleration G can be calculated from the fall duration T and the fall height difference H.

G=2h/t×t (equation three)

When the falling acceleration is less than a predetermined acceleration (e.g., 5m/s ² ) At this time, the user may be considered to be controlling the fall acceleration (e.g., running down a incline), determining that a normal fall is occurring; and when the fall acceleration is greater than or equal to a predetermined acceleration (e.g., 5m/s ² ) At that time, it may be assumed that the user has uncontrolled fall acceleration (e.g., free fall movement, rolling down a steep hill), determining that a severe fall has occurred.

The predetermined height, the predetermined time, and the predetermined acceleration are only exemplary embodiments that can secure a safe fall of a human body, but are not limited thereto. By distinguishing the normal falling and the serious falling, whether the help calling is sent out or not can be judged more accurately, the occurrence of the event of sending out the help calling during the normal falling is prevented, and the rescue efficiency is improved.

In step 205, when it is determined that a severe fall has occurred, a distress message is sent.

In this embodiment, the first environmental information (T1, H1, GPS1, cell id_1, rssi_1, and aoa_1) at the beginning of a severe fall is sent to a preset emergency contact in a text or voice manner; the second environmental information (T2, H2, GPS2, cell id_2, rssi_2, and aoa_2) at the end of the severe fall is transmitted to a preset emergency contact in text or voice through a communication network, here, which may be, for example, a short-range communication network such as bluetooth, wi-Fi direct, or infrared data association (IrDA), or a long-range communication network such as a cellular network, the internet, or a computer network (e.g., LAN or WAN). When the GPS is unavailable due to falling or other factors, the position of the user can be obtained through communication information such as Cell ID, RSSI, AOA and the like, and help is provided for rescue.

Alternatively, environmental information may be sent for a specific time (e.g., five minutes) before the end of a severe fall, so as to obtain information on the user's fall trajectory for five minutes before the end of the fall, and then enter a power saving mode. This has great help in reducing search and rescue scope, judging the place where the fall occurs, presuming the track of the user's action, etc. Therefore, the device can realize the function of recording environment information or movement tracks in daily movement, provide track information in last period of time before touchdown when serious falling occurs, send distress information, and simultaneously have the function of recording movement and the function of calling for help, thereby providing safety guarantee while facilitating daily movement of users.

In step 301, the fall duration T can be determined from the difference between T1 and T2.

At step 302, when the fall duration T is less than a predetermined time (e.g., 1.5 s), the user may be considered to be actively jumping down, determining that a normal fall has occurred; and when the fall duration T is greater than or equal to a predetermined time (e.g., 1.5 seconds), the user may be considered to have a severe fall.

In step 303, a fall height differential H can be determined from the difference between H1 and H2.

In step 304, when the fall height difference is less than a predetermined height (e.g., 10 m), the user may be considered to be actively jumping down, determining that a normal fall has occurred; and when the drop height difference is greater than or equal to a predetermined height (e.g., 10 meters), determining that a severe drop has occurred.

And in step 305, a fall acceleration G is calculated from the fall duration T and the fall height differential H.

At step 306, when the fall acceleration is less than a predetermined thresholdSpeed (e.g. 5 m/s) ² ) At this time, the user may be considered to be controlling the fall acceleration (e.g., running down a incline), determining that a normal fall is occurring; and when the fall acceleration is greater than or equal to a predetermined acceleration (e.g., 5m/s ² ) At that time, it may be assumed that the user has uncontrolled fall acceleration (e.g., free fall movement, rolling down a steep hill), determining that a severe fall has occurred.

In step 401, the user manually turns on the mountain climbing mode. It should be understood that the mountain climbing mode herein is merely an example, and any movement or activity that may be subject to a risk of falling may be used as an embodiment of the present disclosure.

In step 402, an acceleration sensor detects real-time acceleration.

In step 403, whether a fall occurs is determined by the acceleration detected by the acceleration sensor, and when the acceleration in the vertical direction is greater than 0, it is determined that the fall occurs, and step 404 is continuously performed; when the acceleration in the vertical direction is equal to 0, it is determined that a fall has not occurred, and the process returns to step 402.
