The embodiment of the application provides a drop processing method and a related product, which can improve the safety of electronic equipment when the electronic equipment falls to the ground and prolong the service life of the electronic equipment. Embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flow chart of a drop processing method according to an embodiment of the present disclosure. The method described in fig. 1 is applied to an electronic device including an electromagnet, and electromagnetism can be generated when the electronic device is electrified, and the position and the specific structure of the electromagnet are not limited in the application. As shown in fig. 1, includes:
101: and if the electronic equipment is detected to be in a falling state, acquiring a ground image.
The application does not do the injectness to the detection of falling state, and is optional, acquires the gravity acceleration value through gravity sensor, according to the gravity acceleration value is confirmed with the acceleration value of predetermineeing whether electronic equipment is in the state of falling.
The gravity sensor (G-sensor) is used for detecting the direction and magnitude of acceleration, and is equivalent to detecting the motion state of the electronic device, the function of the gravity sensor is relatively simple to understand, changes of acceleration force, such as shaking, falling, rising, falling and other movement changes can be mainly sensed and converted into electric signals by the gravity sensor, and then the functions with good program design can be completed after calculation and analysis of the microprocessor.
Referring to fig. 1A, the specific principle of the gravity sensor is that the acceleration direction includes an X axis, a Y axis and a Z axis. The X axis and the Y axis are parallel to the plane of the electronic device 100, the X axis is the width direction of the electronic device 100, the Y axis is the length direction of the electronic device 100, and the Z axis is perpendicular to the plane of the electronic device 100.
The gravity acceleration value is specifically the acceleration value vertically downward in the Z-axis direction, and is generally 9.8m/s2Acceleration value in m/s2. If the gravity acceleration value is matched with a preset acceleration value, the electronic equipment is in a falling state; and if the gravity acceleration value is not matched with the preset acceleration value, the electronic equipment is not in a falling state.
It should be noted that the gravitational acceleration value varies with the geographical position, and the gravitational acceleration value of an object near the earth is generally between 9.78m/s2To 9.83m/s2In the meantime. Therefore, if the electronic device is determined to be in the falling state by the gravity acceleration value, the gravity acceleration value of the geographical location of the electronic device needs to be obtained in advance. When the electronic equipment falls off, due to the fact that air resistance and gravity acceleration values of all regions are different, the preset acceleration value and the gravity acceleration have certain errors, and therefore the preset acceleration value can be set to be a value which is lower than the gravity acceleration by a certain range, such as 9.3m/s2。
If the electronic equipment is detected not to be in the falling state, continuously detecting whether the electronic equipment is in the falling state; and if the electronic equipment is detected to be in a falling state, acquiring a ground image.
The method is not limited to how to acquire the ground image, and the ground image can be acquired by image acquisition equipment such as a front camera or a rear camera arranged on the electronic equipment, namely, the camera facing the ground is determined by a gravity sensor to acquire the ground image; ground images and the like stored in a server or satellite positioning can also be acquired.
102: and collecting the magnetic induction intensity of the environment.
The magnetic induction intensity (magnetic flux density) is a vector used to describe the physical quantity of the strength and direction of the magnetic field, and is generally denoted by symbol B, and the international common unit is tesla (symbol T). Magnetic induction is also referred to as magnetic flux density or magnetic flux intensity. In physics, the strength of a magnetic field is expressed by magnetic induction, and the higher the magnetic induction is, the stronger the magnetic induction is, and the lower the magnetic induction is, the weaker the magnetic induction is.
The magnetic field intensity of the environment can be collected through a magnetic field sensor (M-sensor) in the electronic equipment, and the magnetic field intensity of the environment can also be obtained through magnetic data provided by an electronic compass sensor in the electronic equipment.
The environmental magnetic induction intensity is environmental magnetic field data of an X axis, a Y axis and a Z axis in the electronic equipment. The units of this value are microtesla (micro-Tesla), expressed as uT; gaussian (Gauss), 1Tesla ═ 10000Gauss, is also possible.
103: and determining target magnetic field parameters and a target falling place according to the environmental magnetic induction and the ground image.
When the electromagnet is electrified, a magnetic field can be generated, and the falling direction of the electronic equipment is adjusted by combining the environmental magnetic induction intensity, so that the falling place of the electronic equipment is changed. The target magnetic field parameters and the target falling place are determined according to the current environmental magnetic induction and the ground image, so that an electromagnet in the electronic equipment works according to the target magnetic field parameters and falls to the safer target falling place.
Optionally, the falling height of the electronic device is obtained; identifying the ground image to obtain a plurality of target areas; selecting the target falling place from the target areas according to the falling height and the environmental magnetic induction intensity; and determining the target magnetic field parameters according to the target falling place and the environmental magnetic induction intensity.
The method for acquiring the falling height is not limited, and the falling height can be acquired through depth of field information in the ground image and can be acquired by combining a distance sensor in the electronic equipment.
The distance sensor includes but is not limited to an infrared sensor, a capacitance sensor, an ultrasonic sensor, an ambient light sensor, a proximity sensor and the like, is used for detecting the distance between an object and the electronic equipment, has the unit of centimeter, and can adjust the screen brightness when receiving the call according to the distance so as to save the electric quantity.
Optionally, when the electronic device is detected to be in a falling state, the distance sensor is started; receiving detection data reported by the distance sensor; acquiring a time interval between the moment of starting the distance sensor and the moment of receiving the detection data; and acquiring the falling height according to the detection data and the time interval.
That is, after the distance sensor detects the distance data, the distance sensor reports the detection data, and the distance between the electronic device and the ground, that is, the falling height, is obtained according to the time interval between the falling state detection and the detection data reporting and the detection data.
It should be noted that a certain time error exists between the electronic device falling and receiving the detection data, the time error can be obtained according to the preset duration and the time interval, and then the height error is obtained according to the time error; and acquiring the falling height according to the height error and the detection data.
In the present application, the time error t can be obtained by the following formula:
t＝t1+t2(1)
wherein, t1For a predetermined duration, t2Are time intervals. For example, the preset duration t10.2s, the time interval t obtained2At 0.1s, the time error t is 0.3 s.
Height error H1Can be obtained by the following formula:
H1＝0.5×g×t2(2)
where g is the gravitational acceleration and t is the time error described above. For example, if the calculated time error t is 0.3s, the height error H can be calculated1Is 0.441 m.
Therefore, the drop height H can be obtained by the following formula:
H＝H1+H2(3)
wherein H1For the above-mentioned height error, H2Is the detection data of the distance sensor. For example, the calculated height error H10.441m, detection data H2At 1m, the drop height H can be calculated to be 1.441 m.
Therefore, after the detection data of the distance sensor are received, the time interval between the moment of starting the distance sensor and the moment of receiving the detection data is obtained, then the falling height of the electronic equipment is obtained according to the detection data and the time interval, the detection data are corrected according to the time error in consideration of the time error of receiving the detection data, and therefore the accuracy of falling height detection can be improved.
The method for determining the target area is not limited, and the area which is easy to cause the electronic equipment to break or the touch display screen to be cracked should be avoided. Optionally, performing image recognition on the ground image to obtain at least one designated area; and dividing the ground image according to the at least one designated area to obtain a plurality of target areas.
The designated area includes, but is not limited to, a water area and a raised area, and the ground material is an area made of a designated material (the designated material is not limited in this application, and may be a harder material, such as cement, ceramic tile, etc.).
The image recognition method of the ground image is not limited in the present application, and may be gray scale image segmentation, color image segmentation, texture image segmentation, and the like, and the segmentation methods may include a threshold segmentation method, an edge detection method, a region extraction method, segmentation based on wavelet transformation, segmentation based on a genetic algorithm, a segmentation method combined with a specific theoretical tool, and the like.
It can be understood that the ground image is subjected to image recognition to obtain a designated area for avoiding falling, and then the ground image is divided into a plurality of target areas according to the specific positions of the designated area, so that the plurality of target areas are all areas for falling safely, and the falling safety of the electronic equipment is improved conveniently.
For example, as shown in fig. 1B, in the ground image, the designated areas are a first area including a puddle and a second area including a convex area, and the ground image is divided according to the first area and the second area to obtain a plurality of target areas: a third region, a fourth region, a fifth region, a sixth region, a seventh region, an eighth region, and a ninth region.
Further, if all the ground images are designated areas, acquiring a damage value of each designated area, and selecting the designated area corresponding to the minimum damage value as a target falling place, so that the safety caused by falling is reduced; and if the ground image does not contain the designated area, directly dividing the ground image into a plurality of target areas, wherein the plurality of target areas can divide the ground image by taking the target landing place as an origin, or divide the ground image according to the size of the electronic equipment.
The method for selecting the target falling site from the target area is not limited, and any one site in the target area can be selected, a site corresponding to the minimum power consumption for starting the target magnetic field parameter consumption can be selected, and a site closest to the target landing site can be selected.
The method comprises the steps of determining target magnetic field parameters according to a target falling place and environmental magnetic induction intensity, and optionally determining a target landing point and landing time of the electronic equipment in a free-falling state; determining a target distance between the target landing site and the target fall site; determining a horizontal acceleration according to the target distance and the landing time; determining the horizontal stress of the electronic equipment according to the horizontal acceleration; and determining the target magnetic field parameters according to the horizontal stress and the gravity corresponding to the environmental magnetic induction intensity.
As shown in FIG. 1CWhen the electronic device 100 detects a falling state, the target landing point N performs a free-fall motion, that is, the electronic device vertically falls to a corresponding place, and then the falling height H is 0.5gt3 2Calculating to obtain the landing time t3Target distance S between target landing site N and target falling site M, landing time t3A horizontal acceleration corresponding to the target distance S, and a horizontal force F corresponding to the horizontal acceleration. According to the principle, the electronic equipment can be understood to generate a magnetic field and a horizontal stress F when the electromagnet works according to the target magnetic field parameters, and the falling path of the electronic equipment is changed through the horizontal stress F and the gravity G corresponding to the environmental magnetic induction intensity, so that the electronic equipment falls to a target falling place.
It should be noted that, since the free-fall motion is a uniform linear motion with an initial velocity of 0, and environmental factors such as wind power and the like are not considered, the target landing point and the landing time may be approximate to a falling place and a falling duration corresponding to the falling of the electronic device.
There are many situations where electronic devices fall, and some fall may cause great damage to the electronic devices, for example, the electronic devices fall from a high place to the ground, resulting in screen breakage and the like. However, some falling does not have great influence on the electronic device, for example, the electronic device slips from the hand of the user to the desk, and the electronic device generally does not have the problems of screen breaking, circuit board damage and the like. And when the falling height is small, the generated magnetic field may not achieve the preset effect. Optionally, when the falling height is greater than a preset threshold, the step of collecting the environmental magnetic induction intensity is performed.
This application does not do the injecion to predetermineeing the threshold value, it is 1 meter to assume to predetermine the threshold value, be in promptly detecting electronic equipment and fall the state, and fall when highly being greater than 1 meter this moment, then gather environment magnetic induction intensity, otherwise, adopt other modes to protect or do not take protective measures, thereby control opening of magnetic sensor or electron compass sensor, avoid carrying out the problem of falling the protection and the electric quantity waste that brings blindly effectively, can save electronic equipment's consumption, be convenient for improve electronic equipment's security when falling to the ground.
104: and driving an electromagnet to work according to the target magnetic field parameters so as to enable the electronic equipment to fall to the target falling place.
When the electromagnet works according to target magnetic field parameters, the falling direction of the electronic equipment can be adjusted by the generated magnetic field and the environmental magnetic induction intensity, so that the electronic equipment falls to a safer target falling place, the safety of the electronic equipment when falling to the ground can be improved, and the service life of the electronic equipment is prolonged.
It can be understood that if the electronic equipment is detected to be in a falling state, a ground image is obtained, the environmental magnetic induction is collected, the target magnetic field parameter and the target falling place are determined according to the environmental magnetic induction and the ground image, and the electromagnet is driven to work according to the target magnetic field parameter so that the electronic equipment falls to the target falling place. That is to say, the falling direction of the electronic equipment is changed by utilizing the environmental magnetic induction and the target magnetic field parameters, so that the electronic equipment falls to a safer target falling place, the safety of the electronic equipment when falling to the ground can be improved, and the service life of the electronic equipment is prolonged.
