All other embodiments obtained by a person of ordinary skill in the art without any inventive work according to the embodiments of the present application are within the scope of the present application.
In order to better understand the technical solutions, the technical solutions of the present application are described in detail below with reference to the drawings and specific embodiments, and it should be understood that the specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, and are not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
Fig. 1 shows that this application provides an intelligent bracelet 1, and this bracelet 1 includes: the gyroscope 2 and the ultrasonic ranging module 3; the gyroscope 2 is used for detecting the speed of hand movement of a user, and the ultrasonic ranging module 3 is used for detecting the height between the hand of the user and the ground. It should be understood that the smart bracelet should include a timer, a positioning module, a warning module, a controller, a computing module, a communication module, and the like.
Example one
On the basis of the smart bracelet shown in fig. 1, the following detailed description is made on a method for monitoring children provided in the embodiments of the present application with reference to the drawings of the specification, and a specific implementation manner of the method may include the following steps (a flow of the method is shown in fig. 2):
step 201, the smart band detects whether the speed of the hand movement of the child wearing the smart band is greater than a first threshold value.
Usually, a gyroscope can detect the angular velocity of rotation when a physical quantity deflects and tilts, and can measure the movement during rotation and deflection, so as to judge the actual movement of a user. Therefore, when the gyroscope is applied to the smart bracelet, the motion speed of the hands of the child wearing the smart bracelet can be detected through the gyroscope, and the detected motion speed of the hands of the child is compared with a value preset in the database so as to determine the motion of the child.
Specifically, a reference coordinate system is established by taking the axial direction of a body trunk of a child when the child stands as a Z axis, and a gyroscope detects whether the angular speed of the hand movement of the child relative to the Z axis is greater than a first threshold value; or detecting whether the speed of the hand movement of the child in the Z-axis direction is greater than the first threshold value.
Step 202, if the speed of detecting the hand motion of the child is greater than a first threshold value, the smart bracelet detects whether the distance between the hand of the child and the ground is within a preset range.
When the speed that detects children's hand motion when intelligent bracelet is greater than first threshold value, whether the distance that detects children's hand and ground through ultrasonic ranging module is at predetermined within range, wherein, ultrasonic ranging module can be miniature ultrasonic radar, also can be ultrasonic sensor, can realize ultrasonic ranging's device in this application all can, does not do the restriction here.
Specifically, the ultrasonic ranging module transmits ultrasonic waves to the ground along the Z-axis direction, receives the ultrasonic waves transmitted from the ground after a certain period of time, records the time when the ultrasonic ranging module transmits the ultrasonic waves as T1 and the time when the reflected ultrasonic waves are received as T2, determines that the distance between the hand of the child and the ground is S (V (T2-T1))/2 according to the propagation speed V of the ultrasonic waves in the air being 340m/S and the time difference T2-T1 between the ultrasonic ranging module transmitting and receiving the ultrasonic waves, and determines whether the distance S is within a preset range, for example, the preset range is [10cm, 140cm ] according to the detected distance between the hand of the child and the ground.
For example, the ultrasonic ranging module is a micro ultrasonic radar, the preset range is [10cm, 140cm ], when the intelligent bracelet detects that the angular velocity of the motion of the hand of the child relative to the Z axis is greater than a first threshold value, the calculation module in the intelligent bracelet determines the angle of the hand of the child deviating from the Z axis based on the angular velocity measured by the gyroscope, and controls the transmitting device of the micro ultrasonic radar to be vertical to the ground through the control module, then, the micro ultrasonic radar transmits ultrasonic waves to the ground, the time for transmitting the ultrasonic waves is recorded as 18:00, the micro ultrasonic radar receives the ultrasonic waves reflected by the ground after 0.2 milliseconds, therefore, based on the distance calculation formula S ═ V ═ (T2-T1))/2, it was determined that the distance between the hand of the current child and the ground was 6.8cm, since the preset range is [10cm, 140cm ], the distance between the hand of the child and the ground is not within the preset range.
Step 203, if the intelligent bracelet detects that the distance between the hand of the child and the ground is not within the preset range, sending a safety verification request to a terminal bound with the intelligent bracelet.
Specifically, the smart band can be bound with a plurality of terminals, and different priorities for controlling the smart band can be set for each terminal in the binding process, for example, the plurality of terminals include a terminal used by dad and a terminal used by mom, and since mom may take children for a long time, the priority of the terminal used by mom is set to be the highest, and the priority of the terminal used by dad is set to be the next lowest. After the intelligent bracelet is bound with a plurality of terminals, the intelligent bracelet can interact with information among a plurality of terminals, acquire position information of the plurality of terminals, and can be positioned at the current position where children are located through the positioning module. When the intelligent bracelet detects that the distance between the hand of the child and the ground is not in after the preset within range, the intelligent bracelet to with the terminal that the intelligent bracelet was bound sends the safety verification request, because the terminal that binds with the intelligent bracelet has a plurality of terminals, consequently, the mode that the intelligent bracelet sent the safety verification request to the terminal has a plurality ofly, possible mode as follows:
mode 1: and the intelligent bracelet sends a security verification request to all terminals bound with the intelligent bracelet.
Mode 2: the intelligent bracelet acquires the position information of the terminal bound with the intelligent bracelet, determines the terminal closest to the intelligent bracelet based on the position information of the terminal, and sends a safety verification request to the terminal closest to the intelligent bracelet.
Mode 3: the intelligent bracelet obtains the priority of the control intelligent bracelet of the terminal, determines the terminal with the highest priority based on the priority of the control intelligent bracelet, and sends the safety verification request to the terminal with the highest priority.
And 204, the intelligent bracelet receives a reply signal returned by the terminal based on the security verification request, and determines whether to generate a warning signal based on the reply signal.
The reply signal comprises a safety signal or a danger signal, after one or more terminals bound with the smart band receive a safety verification request, a user corresponding to the terminal can input the reply signal to the terminal after confirming the state of the child, or the terminal automatically replies according to a preset reply strategy, for example, the preset reply strategy is that when the smart band detects that the distance between the terminal bound with the smart band is less than a second threshold value, the safety signal is automatically replied.
Specifically, because the smart band can be bound to a plurality of terminals, the smart band can receive reply signals returned by the plurality of terminals based on the security verification request, and therefore, the manner in which the smart band determines whether to generate the warning signal based on the reply signals includes a plurality of manners, and possible manners are as follows:
mode 1: the intelligent bracelet determines whether to generate a warning signal or not according to the first received reply signal based on the sequence of the time for receiving the reply signals.
Mode 2: the intelligent bracelet determines whether to generate a warning signal or not based on the received reply signal returned by the terminal closest to the intelligent bracelet.
Mode 3: the intelligent bracelet determines whether to generate a warning signal or not based on the received reply signal returned by the terminal with the highest control priority.
The warning signal can be speech signal, the signal of control light or alarm signal, the intelligence bracelet is based on behind the received reply signal of above-mentioned mode determination, when the reply signal is danger signal, the intelligence bracelet probably generates speech signal, and play this pronunciation out through the megaphone, so that remind the adult of children's annex to notice this children probably are in unsafe state, the intelligence bracelet also probably generates the signal of control light, the light of signal control intelligence bracelet through control light is not stopped the scintillation, so that remind the adult of children's annex to notice this children probably are in unsafe state, the intelligence bracelet also probably generates alarm signal, through the automatic alarm telephone that dials of this alarm signal control intelligence bracelet.
According to the scheme provided by the embodiment of the application, the intelligent bracelet detects the movement speed of the hands of the child through the gyroscope, when the movement speed of the hands of the child is larger than a first threshold value, the distance between the hands of the child and the ground is further detected through the ultrasonic ranging module, whether a safety verification request is sent to a bound terminal is determined, and whether a warning signal is generated is determined based on a skin care signal returned by the terminal. Therefore, in this application scheme, intelligence bracelet combines to guardianship children through gyroscope and ultrasonic ranging module, has improved the effect of intelligent bracelet guardianship.
Further, in order to get rid of children in the normal motion process, hand movement speed is greater than the condition of first threshold value, and intelligent bracelet is detecting whether the distance of children's hand and ground is before the within range that predetermines, still includes: determining the motion track of the hand of the child within a preset time period, and judging whether the motion track is matched with the normal motion track of the hand of the child in the history record; and if not, detecting whether the distance between the hand of the child and the ground is within a preset range.
The intelligent bracelet can take notes the orbit of the normal hand motion of children in the preset time quantum in-process, and when the speed that the intelligent bracelet detected children's hand motion was greater than first threshold value, a plurality of time points of preset time quantum are confirmed to the intelligent bracelet to detect the position that a plurality of time points correspond, based on the action orbit of children's hand in this preset time quantum is confirmed to the position of a plurality of time points, compares this motion orbit with the orbit of the normal hand motion of record, if the orbit of the normal hand motion at the record does not have the orbit the same with this motion orbit, then detects whether children's hand is at the within range of predetermineeing with the distance on ground.
For example, the preset time period is 3 nanoseconds, when the hands of the child normally move, the smart band takes 3 nanoseconds as a time reference, records the track of the motion of the hands of the child every 3 nanoseconds, stores the track in the database, determines the track of the motion of the hands of the child within 3 nanoseconds after the moment when the speed of detecting the motion of the hands of the child by the smart band is greater than a first threshold value, compares the track of the motion of the hands of the child within 3 nanoseconds with the motion track in the database, and detects whether the distance between the hands of the child and the ground is within a preset range if the corresponding track cannot be found in the database.
In the scheme that this application was implemented and is provided, the motion trail of intelligent bracelet through the children hand that detects in the predetermined period of time confirms whether the motion trail matches with historical record's normal motion trail, gets rid of the normal motion that children hand velocity of motion is greater than first threshold value through the children hand motion trail that detects in the predetermined period of time, has avoided the detection to children normal motion and has sent the safety verification request to the terminal, has not only reduced the consumption of intelligent bracelet, has still improved user's experience effect.
