In order to make the technical solutions of the present invention better understood by those skilled in the art, 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, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. The embodiments based on the present invention should fall into the protection scope of the present invention.
It is understood that the terminal device according to 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 Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP) device, a notebook Computer, a notebook (Note Pad), a Wireless Broadband (Wibro) terminal, a tablet Computer (PC), a smart PC, a Point of Sales (POS), a car Computer, and the like.
The terminal device may also comprise a wearable device. The wearable device may be worn directly on the user or may be a portable electronic device integrated into the user's clothing or accessory. Wearable equipment is not only a hardware device, can realize powerful intelligent function through software support and data interaction, cloud end interaction more, for example: the system has the functions of calculation, positioning and alarming, and can be connected with a mobile phone and various terminals. Wearable devices may include, but are not limited to, wrist-supported watch types (e.g., wrist watches, wrist-supported products), foot-supported shoes types (e.g., shoes, socks, or other leg-worn products), head-supported Glass types (e.g., glasses, helmets, headbands, etc.), and various types of non-mainstream products such as smart clothing, bags, crutches, accessories, and the like.
The following further describes the technical solution of the present invention by way of an embodiment, as shown in fig. 1, which is a schematic diagram of an embodiment of a security detection method in an embodiment of the present invention, and the method may include:
101. the first wearable device obtains a first difference absolute value of any two air pressure values and a current posture of the user within a first preset time length.
Optionally, the obtaining, by the first wearable device, a first difference absolute value between any two air pressure values and a current posture of the user within a first preset time period may include, but is not limited to, the following implementation manners:
implementation mode 1: the method comprises the steps that a first wearable device detects that the air pressure value of a user changes within a first preset time length; and calculating to obtain a first difference absolute value of any two air pressure values according to the changed air pressure value and the air pressure value before the change, and acquiring the current posture of the user.
It will be appreciated that the user will have a change in air pressure from either high to low or low to high. The first wearable device detects the air pressure change within the preset time length, and can acquire the difference value of any two air pressure values. The difference may be a positive number or a negative number, and is not limited in particular. To facilitate the first wearable device to proceed with the next pressure difference comparison, the difference is optimized as the absolute value of the difference.
Implementation mode 2: the first wearable device obtains a first difference absolute value of any two air pressure values of a user within a first preset time length, and obtains the current posture of the user through detection of the nine-axis posture sensor.
Among them, the nine-axis attitude sensor is a combination of three kinds of sensors. The three sensors are respectively a 3-axis acceleration sensor, a 3-axis gyroscope and a 3-axis electronic compass (geomagnetic sensor). The nine-axis attitude sensor is used as an integrated sensor module, reduces a circuit board and the whole space, and is more suitable for being used in light and portable terminal equipment and wearable equipment. The data accuracy of the integrated sensor not only relates to the accuracy of the device, but also relates to the correction after welding assembly and a matching algorithm aiming at different applications. The appropriate algorithm can fuse data from various sensors, make up for the deficiency of a single sensor in calculating accurate position and direction, and therefore realize high-precision motion detection.
The 3-axis acceleration sensor measures acceleration in each direction in space. The 3-axis acceleration sensor utilizes inertia of a gravity block, the gravity block can generate pressure in X, Y, Z directions (front, back, left, right, up and down) when the 3-axis acceleration sensor moves, a piezoelectric crystal is utilized to convert the pressure into an electric signal, the pressure in each direction is different along with the change of the movement, and the electric signal also changes, so that the acceleration direction and the speed of the mobile phone are judged.
A 3-axis gyroscope is a device for measuring angles and maintaining orientation. Such as: in games such as a flight game, a sports game, a first-view-angle shooting game and the like, the displacement of the hands of a player can be completely monitored, so that various game operation effects are realized.
A 3-axis electronic compass can describe substantially the full motion state of a wearable device using a 3-axis acceleration sensor and a 3-axis gyroscope. However, with long-time movement, accumulated deviation also occurs, and the movement posture cannot be accurately described, such as the inclination of the control picture. The 3-axis electronic compass measures the earth magnetic field, corrects and compensates through the absolute pointing function, and can effectively solve the accumulated deviation, so that the motion direction, the posture angle, the motion force, the motion speed and the like of the human body are corrected.
Implementation mode 3: the first wearable device acquires a first difference absolute value of any two air pressure values of a user within a first preset time length, and acquires a picture and/or a video of the current posture of the user through a camera; and the first wearable device analyzes the current posture of the user according to the picture and/or the video.
102. And the first wearable device acquires a reminding message when the first difference absolute value is larger than a preset pressure difference threshold value and the current posture is a jumping posture.
The jumping gesture may be a gesture that the user prepares to jump down at a high position, or a gesture that the user prepares to jump up at a low position, which is not limited herein.
Optionally, the first wearable device obtains the reminding message when the first absolute difference value is greater than the preset pressure difference threshold and the current gesture is a jumping gesture, and may further include but is not limited to the following implementation manners:
implementation mode 1: the first wearable device acquires a first duration of the current posture of the user; the first wearable device acquires a reminding message when the first difference absolute value is larger than a preset pressure difference threshold value, the current posture is a jumping posture, and the first duration is larger than a preset duration.
For example, assume that the preset duration of the tripped position is 3 seconds and the preset differential pressure threshold is 3 pa. A child wears a wearable device and is ready to jump from the second level of steps to the ground, the wearable device detects that the first time period for the child to jump from the second level of steps to the ground is 5 seconds longer than a preset time period for 3 seconds, and the wearable device also detects that the absolute value of the pressure difference is 6.66 pa longer than a preset pressure difference threshold value for 3 pa. At this time, the child may obtain a similar reminder message such as "pay attention to safety, do not jump". Wherein, the height of each liter is 1 meter, the atmospheric pressure is reduced by 11.1 Pa, and if one layer of step is 30 cm, the absolute value of the pressure difference of the two layers of steps is 6.66 Pa.
Implementation mode 2: the first wearable device obtains data of the current posture where the user is located; the first wearable device acquires transformation data of the current posture according to a coordinate system and a world coordinate system corresponding to the data of the current posture; the first wearable device acquires a reminding message when the first difference absolute value is larger than a preset pressure difference threshold value and the transformation data of the current posture is successfully matched with the transformation data of the preset posture; wherein, the coordinate system corresponding to the data of the current attitude is a machine body coordinate system; and a coordinate system corresponding to the transformation data of the current posture and the transformation data of the preset posture is a world coordinate system.
The body Coordinate System (UCS) is originally defined as a three-dimensional orthogonal Coordinate System fixed on an aircraft or plane and following the right-hand rule, and has an origin O, and X, Y and Z axes. Wherein, the focus of initial point O position aircraft or aircraft, the positive direction of X axle is located the reference plane of aircraft or aircraft, and is on a parallel with the axis and points to aircraft nose the place ahead, and the positive direction of Y axle is perpendicular to the right-hand direction of reference plane and pointing to aircraft or aircraft, the positive direction of Z axle is located reference plane, perpendicular to XOY plane, and the below of pointing to 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 called the earth surface inertial Coordinate System, is an absolute Coordinate System in the System, i.e. a fixed Coordinate System, which is a default Coordinate System. In this embodiment, it is a three-dimensional coordinate system having an origin O and X, Y and Z axes. The positive direction of the X axis generally points to the east, the positive direction of the Y axis generally points to the north, and the positive direction of the Z axis generally points to the sky. The world coordinate system is used to determine a state of motion of the first wearable device relative to the ground.
It is understood that the transformation data of the current attitude is transformation data between the body coordinate system and the world coordinate system to which the data of the current attitude corresponds.
Implementation mode 3: the first wearable device acquires data of the current posture of the user; the first wearable device acquires 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 acquires a reminding message when the first difference absolute value is larger than a preset pressure difference threshold value and the transformation data of the current posture is successfully matched with the transformation data of the preset posture; the coordinate system corresponding to the current attitude data, the preset attitude data, the current attitude transformation data and the preset attitude transformation data is a world coordinate system.
It is understood that the transformation data of the current posture is transformation data obtained by comparing the data of the current posture with the data of the preset posture.
For example, assume that the data of the preset posture is (X0, Y0, Z0), the transformation data of the preset posture is (X2, Y2, Z2), and the transformation data of the current posture is the difference between the data of the current posture and the data of the preset posture. If the data of the current posture of the child detected by the first wearable device is (X1, Y1, Z1) and the transformation data of the current posture (X1-X0, Y1-Y0, Z1-Z0), when the absolute value of the first difference of the first wearable device is larger than the preset pressure difference threshold value and the transformation data of the current posture (X1-X0, Y1-Y0, Z1-Z0) successfully matches the transformation data (X2, Y2, Z2) of the preset posture, the user obtains a "safety attention" reminding message. The obtaining formula of the transformation data of the current posture is not limited to the above representation, and may be other representation manners, which is not specifically limited herein.
Implementation mode 4: the first wearable device acquires a second difference absolute value of the initial speed value and the termination speed value of the user within a second preset time length; the first wearable device acquires the reminding message when the first difference absolute value is larger than a preset pressure difference threshold value, the transformation data of the current gesture successfully matches the transformation data of the preset gesture, and the second difference absolute value is larger than a preset speed difference threshold value.
For example, assume that the second preset duration is 2 seconds, the initial velocity value is 0, and the preset velocity difference threshold is 2.5 meters per second. The method comprises the steps that a child wears a wearable device and is ready to jump from a second-layer step to the ground, the wearable device detects that the speed value of the child on the second-layer step is an initial speed value, the ending speed value can be calculated to be 3.43 meters per second and larger than a preset speed difference threshold value by 2.5 meters per second according to a formula, the absolute value of a first difference value is also detected to be larger than a preset pressure difference threshold value, and the transformation data of the current posture are successfully matched with the transformation number of the preset posture. At this time, the child may obtain a similar reminder message such as "pay attention to safety, do not jump". Wherein, a step of 30 cm is assumed, and h is the basis 1 / 2 gt 2 The time is obtained, and the termination speed value is obtained from v ═ gt.
Implementation mode 5: the first wearable device acquires a third difference absolute value of any two acceleration values of the user within a second preset time length; and the first wearable device acquires a reminding message under the conditions that the first difference absolute value is larger than a preset pressure difference threshold value, the transformation data of the current posture is successfully matched with the transformation data of the preset posture, and the third difference absolute value is larger than a preset speed difference threshold value.
It will be appreciated that the velocity is related to acceleration as follows: (1) acceleration describes how fast the speed changes, and velocity describes how fast the position changes. (2) Acceleration is the rate of change of velocity over time and velocity is the rate of change of position over time.
103. The first wearable device outputs the reminder message.
Optionally, the first wearable device outputs the alert message, which may include but is not limited to the following implementation manners:
implementation mode 1: the first wearable device prompts for the reminder message.
Implementation mode 2: the first wearable device sends the reminding message to the terminal device.
