In order for those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the present invention examples, but not all examples. Based on the embodiments of the present invention, all should belong to the protection scope of the present invention.

It can be understood that the terminal device involved in the embodiment of the present invention may include a general handheld electronic terminal device, such as a mobile phone, a smart phone, a portable terminal, a terminal, a personal digital assistant (Personal Digital Assistant, PDA), and a portable multimedia player. personal media player (PMP) devices, notebook computers, notebook (Note Pad), wireless broadband (Wireless Broadband, Wibro) terminals, tablet computers (Personal Computer, PC), smart PCs, point of sales (Point of Sales, POS) and Car computer, etc.

Terminal devices may also include wearable devices. A wearable device can be worn directly on the user, or a portable electronic device integrated into the user's clothing or accessories. Wearable device is not only a hardware device, but also can realize powerful intelligent functions through software support, data interaction, and cloud interaction, such as: computing function, positioning function, alarm function, and can also be connected to mobile phones and various terminals. Wearable devices may include, but are not limited to, wrist-supported watches (such as watches, wrists, etc.), foot-supported shoes (such as shoes, socks, or other products worn on the legs), and head-supported products. Glass categories (such as glasses, helmets, headbands, etc.) and smart clothing, school bags, crutches, accessories and other non-mainstream product forms.

The technical solution of the present invention will be further described below by way of embodiments. As shown in FIG. 1 , it is a schematic diagram of an embodiment of the method for security detection in the embodiment of the present invention, which may include:

101. The first wearable device acquires the absolute value of the first difference between any two air pressure values of the user within a first preset time period, and the current posture of the user.

Optionally, the first wearable device obtains the absolute value of the first difference between any two air pressure values of the user within the first preset duration, and the current posture of the user, which may include but not be limited to the following implementations:

Implementation 1: The first wearable device detects that the air pressure value of the user changes within the first preset time period; according to the air pressure value after the change and the air pressure value before the change, the first difference between any two air pressure values is calculated and obtained Absolute value, and get the current posture of the user.

It is understandable that the user will have a change in air pressure whether from high to low or from low to high. The first wearable device detects a change in air pressure within a preset time period, and can obtain the difference between any two air pressure values. The difference may be a positive number or a negative number, which is not specifically limited here. In order to facilitate the first wearable device to compare the pressure difference in the next step, the difference value is optimized as the absolute value of the difference value.

Implementation Mode 2: The first wearable device acquires the absolute value of the first difference between any two air pressure values within the first preset duration of the user, and detects the current posture of the user through the nine-axis posture sensor.

Among them, the nine-axis attitude sensor is a combination of three sensors. The three sensors are 3-axis acceleration sensor, 3-axis gyroscope and 3-axis electronic compass (geomagnetic sensor). As an integrated sensor module, the nine-axis attitude sensor reduces the circuit board and overall space, and is more suitable for use in lightweight and portable terminal devices and wearable devices. In addition to the accuracy of the device itself, the data accuracy of the integrated sensor also involves correction after welding and assembly, as well as matching algorithms for different applications. Appropriate algorithms can fuse data from multiple sensors, making up for the insufficiency of a single sensor in calculating accurate position and orientation, enabling high-precision motion detection.

The 3-axis acceleration sensor measures acceleration in all directions in space. The 3-axis acceleration sensor utilizes the inertia of a "gravity block". When the 3-axis acceleration sensor is moving, the "gravity block" will generate pressure in the X, Y, and Z directions (front, back, left, right, up, down), and then use a piezoelectric The crystal converts this pressure into an electrical signal. With the change of motion, the pressure in each direction is different, and the electrical signal is also changing, so as to judge the acceleration direction and speed of the mobile phone.

A 3-axis gyroscope is a device used to measure angles and maintain orientation. For example, in games such as flying games, sports games, and first-perspective shooting, the displacement of the player's hand can be completely monitored, thereby realizing various game operation effects.

The 3-axis electronic compass uses a 3-axis acceleration sensor and a 3-axis gyroscope, which can basically describe the complete motion state of the wearable device. However, with the long-term movement, there will also be accumulated deviations, which cannot accurately describe the movement posture, such as the tilt of the control screen. The 3-axis electronic compass uses the measurement of the earth's magnetic field and performs correction and compensation through the absolute pointing function, which can effectively solve the accumulated deviation, thereby correcting the movement direction, attitude angle, movement strength and speed of the human body.

Implementation mode 3: the first wearable device obtains the absolute value of the first difference between any two air pressure values of the user within the first preset time period, and obtains a picture of the current posture of the user through a camera, and/or , video; the first wearable device analyzes and obtains the current posture of the user according to the picture and/or the video.

102. The first wearable device acquires a reminder message when the absolute value of the first difference is greater than a preset pressure difference threshold and the current posture is a jumping posture.

The jumping posture may be a posture of the user preparing to jump downward from a high place, or a posture of the user preparing to jump upward from a low place, which is not specifically limited here.

Optionally, when the absolute value of the first difference is greater than the preset pressure difference threshold, and the current posture is a jumping posture, the first wearable device obtains a reminder message, which may also include, but is not limited to, the following implementations: Way:

Implementation mode 1: the first wearable device obtains the first duration of the current posture of the user; the absolute value of the first difference of the first wearable device is greater than the preset pressure difference threshold, and the current posture is jumping. and when the first duration is greater than the preset duration, obtain a reminder message.

Exemplarily, it is assumed that the preset duration of the jumping posture is 3 seconds, and the preset pressure difference threshold is 3 Pa. A child is wearing a wearable device and is about to jump from the second step to the ground. The wearable device detects that the first time the child is about to jump from the second step to the ground is 5 seconds longer than the preset time of 3 seconds , the wearable device also detected that the absolute value of the differential pressure was 6.66 Pa, which was greater than the preset differential pressure threshold of 3 Pa. At this time, the child will get a similar reminder message such as "Be careful, don't jump". Among them, the atmospheric pressure decreases by 11.1 Pa for every 1 meter rise. Assuming that one step is 30 cm, the absolute value of the pressure difference between the two steps is 6.66 Pa.

Implementation mode 2: the first wearable device obtains the data of the current posture of the user; the first wearable device obtains the transformation data of the current posture according to the coordinate system and the world coordinate system corresponding to the data of the current posture; the The first wearable device obtains a reminder message when the absolute value of the first difference is greater than the preset pressure difference threshold, and the transformation data of the current posture successfully matches the transformation data of the preset posture; wherein, the data of the current posture The corresponding coordinate system is the body coordinate system; the coordinate system corresponding to the transformation data of the current posture and the transformation data of the preset posture is the world coordinate system.

Among them, the User Coordinate System (UCS) was originally defined as a three-dimensional orthogonal coordinate system fixed on the aircraft or aircraft following the right-hand rule, with the origin O and the X, Y and Z axes. The origin O is located at the center of gravity of the aircraft or aircraft, the positive direction of the X-axis is located in the reference plane of the aircraft or aircraft, parallel to the axis and pointing in front of the nose, and the positive direction of the Y-axis is perpendicular to the reference plane and points to the aircraft or To the right of the aircraft, the positive direction of the Z-axis is on the reference plane, perpendicular to the XOY plane, and points below the aircraft or aircraft. In this embodiment, the application object of the body coordinate system is the first wearable device.

The World Coordinate System (WCS), also known as the inertial coordinate system on the earth's surface, is an absolute coordinate system in the system, that is, a fixed coordinate system, which is the default coordinate system. In this embodiment, it is a three-dimensional coordinate system with an origin O and an X-axis, a Y-axis and a Z-axis. Among them, the positive direction of the X-axis usually points to the due east direction, the positive direction of the Y-axis usually points to the due north direction, and the positive direction of the Z-axis usually points to the direction of the sky. The world coordinate system is used to determine the motion state of the first wearable device relative to the ground.

It can be understood that the transformation data of the current posture is the transformation data between the body coordinate system and the world coordinate system corresponding to the data of the current posture.

Implementation mode 3: the first wearable device obtains the data of the current posture of the user; the first wearable device obtains the transformation data of the current posture according to the data of the current posture and the data of the preset posture; the first wearable device obtains the transformation data of the current posture; The wearable device obtains a reminder message when the absolute value of the first difference is greater than the preset pressure difference threshold, and the transformation data of the current posture successfully matches the transformation data of the preset posture; wherein, the data of the current posture, the The data of the preset attitude, the coordinate system corresponding to the transformation data of the current attitude and the transformation data of the preset attitude is the world coordinate system.

It can be understood that the transformation data of the current posture is transformation data obtained by comparing the data of the current posture and the data of the preset posture.

Exemplarily, it is assumed that the data of the preset attitude is (X0, Y0, Z0), the transformation data of the preset attitude is (X2, Y2, Z2), and the transformation data of the current attitude is the data of the current attitude and the preset attitude. difference of the data. If the data of the current posture of a child measured by the first wearable device is (X1, Y1, Z1), and the transformation data of the current posture (X1-X0, Y1-Y0, Z1-Z0), then when the first wearable device measures When the absolute value of the first difference of the wearable device is greater than the preset pressure difference threshold, and the transformation data (X1-X0, Y1-Y0, Z1-Z0) of the current posture successfully matches the transformation data (X2, Y2) of the preset posture , Z2), the user obtains a reminder message of "pay attention to safety". Wherein, the acquisition formula of the transformation data of the current posture is not limited to the above-mentioned representation, and may also be other representations, which are not specifically limited here.

Implementation mode 4: the first wearable device obtains the second absolute value of the difference between the starting speed value and the ending speed value of the user within the second preset duration; the first wearable device obtains the absolute value of the first difference When the value is greater than the preset pressure difference threshold, the transformation data of the current attitude successfully matches the transformation data of the preset attitude, and the absolute value of the second difference is greater than the preset velocity difference threshold, a reminder message is obtained.

Exemplarily, it is assumed that the second preset duration is 2 seconds, the initial speed value is 0, and the preset speed difference threshold value is 2.5 meters per second. A child is carrying a wearable device and is about to jump from the second step to the ground. The wearable device detects that the child's speed on the second step is the starting speed value, and the end speed can be calculated according to the formula If the value is 3.43 meters per second, which is greater than the preset speed difference threshold of 2.5 meters per second, it will also be detected that the absolute value of the first difference is greater than the preset pressure difference threshold, and the transformation data of the current attitude successfully matches the number of transformations of the preset attitude. . At this time, the child will get a similar reminder message such as "Be careful, don't jump". Among them, assuming that one step is 30 cm, the time is calculated according to h= ¹ / ₂ gt ² , and the final speed value is obtained according to v=gt.

Implementation mode 5: the first wearable device obtains the third absolute value of the difference between any two acceleration values of the user within the second preset time period; When the pressure difference threshold is set, the transformation data of the current attitude successfully matches the transformation data of the preset attitude, and the absolute value of the third difference is greater than the preset speed difference threshold, a reminder message is obtained.

It can be understood that the relationship between speed and acceleration is as follows: (1) Acceleration describes the speed of change in speed, and speed describes the speed of change in position. (2) Acceleration is the rate of change of velocity versus time, and velocity is the rate of change of position versus time.

103. The first wearable device outputs the reminder message.

Optionally, the first wearable device outputs the reminder message, which may include but not limited to the following implementations:

Implementation 1: the first wearable device prompts the reminder message.

Implementation mode 2: the first wearable device sends the reminder message to the terminal device.

Furthermore, the voice message may be output at least once.

In this embodiment of the present invention, when the first wearable device detects that the user is within a first preset time period, the absolute value of the first difference between any two air pressure values is greater than the preset pressure difference threshold, and detects that the user's When the current posture is a jumping posture, the user will obtain a reminder message. In this way, when the first wearable device detects that the user is in a relatively dangerous environment and is in a jumping posture, the first wearable device can effectively reduce the risk of an accident for the user by acquiring the reminder message. Used to remind the user to pay attention to safety.

201. The first wearable device acquires the absolute value of the first difference between any two air pressure values of the user within a first preset time period, and the current posture of the user.

202. The first wearable device obtains a reminder message when the absolute value of the first difference is greater than a preset pressure difference threshold and the current posture is a jumping posture

It should be noted that, steps 201-202 are similar to steps 101-102 shown in FIG. 1 in this embodiment, and are not repeated here.

203. If the first wearable device detects a second wearable device within a preset range, send the reminder message to the second wearable device, where the reminder message is used for the second wearable device device output.

Exemplarily, it is assumed that the wearable device worn by the first child detects that there are four children within a range of 10 meters, and each of the four children wears a wearable device. When the first child has a downward jumping posture from a high place or an upward jumping posture from a low place, then the wearable device of the first child will remind the child to pay attention to safety, and will The reminder message for being safe is sent to the other four children, and the four children receive the reminder message and remind the four children to pay attention to safety. In this way, if there are multiple children playing together, the safety of each child can be ensured through mutual safety reminders.
