Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an intelligent bracelet according to an embodiment of the present application.
The specific structure may include:
the optical sensor assembly 100 is arranged on the outer side surface of the bracelet body and used for transmitting the detected illumination intensity to the processing chip 200 of the smart bracelet, wherein the outer side surface of the bracelet body is a surface which is not in contact with an arm when the smart bracelet is worn;
wherein, the bracelet body that this embodiment mentioned is the main part of intelligent bracelet, and the bracelet body specifically is for enclosing into annular structure. This embodiment is acquiescent when the user normally wears intelligent bracelet, and the arm can be the medial surface with the face of intelligent bracelet contact, and other faces except the medial surface on the bracelet body all can be called the lateral surface.
Specifically, light sensor module 100 sets up in the lateral surface of bracelet body for detect the illumination intensity of lateral surface position, it should explain that the light sensor module in this embodiment can include a plurality of light sensor, and a plurality of light sensor can distribute in each position of lateral surface, and the illumination intensity of which positions of the specific detection lateral surface of light sensor module here detects and prescribes a limit. It should be noted that, the light sensor subassembly can detect the illumination intensity of bracelet body lateral surface department at least. The illumination intensity detection of the embodiment aims at detecting illumination information of an external environment where the smart band is located, and if the optical sensor assembly 100 includes one optical sensor, the illumination intensity of only one position of the outer side surface can be detected; if the optical sensor assembly comprises a plurality of optical sensors, the illumination intensity of a plurality of positions of the outer side face can be detected, and the illumination information of the external environment where the intelligent bracelet is located is more accurate according to the illumination intensity of the plurality of positions. The illumination intensity that detects a plurality of positions can avoid appearing when only detecting the illumination intensity of the bracelet body that back of the hand department corresponds, if the user's palm falls down towards ground, the illumination intensity that the bracelet is close to back of the hand department is unchangeable but the illumination intensity that the bracelet is close to palm of the hand department diminishes, the change of the illumination intensity of the environment that intelligent bracelet is located can't really be reflected. Because the user is when normally wearing intelligent bracelet, intelligent bracelet and user's arm are the simultaneous movement, and the illumination intensity around the intelligent bracelet just is equivalent to the illumination intensity that user's arm wore intelligent bracelet position.
In a word, what the illumination intensity that sets up the optical sensor subassembly that the bracelet body lateral surface detected represented is the illumination condition of bracelet body certain part that optical sensor subassembly corresponds, can send the illumination intensity who detects to processing chip 200 so that carry out further analysis. The processing chip 200 is generally a chip disposed inside the smart band, and can perform analysis according to information detected by various sensors or sensor components connected thereto.
The specific structure of the smart bracelet in this embodiment may further include:
the gravity sensor 300 is connected to the processing chip 200, and is configured to send the detected acceleration information of the bracelet body to the processing chip 200;
please refer to fig. 2, fig. 2 is a general view of an intelligent bracelet according to an embodiment of the present application, and since the processing chip and the gravity sensor are disposed inside the intelligent bracelet, only the optical sensor assembly 100 can be observed in fig. 2. The gravity sensor 300 of the present embodiment is a cantilever type displacement device made of an elastic sensing element, and an energy storage spring made of an elastic sensing element is used to drive an electrical contact, so as to complete the conversion from the gravity change to the electrical signal. Gravity sensor can detect the acceleration information of bracelet body, because the user is when normally wearing intelligent bracelet, and intelligent bracelet is synchronous motion with user's arm, and the acceleration state of intelligent bracelet just is equivalent to the acceleration state of user's arm.
Since the gravity sensor 300 is used to detect acceleration information, the gravity sensor 300 does not need to be disposed on the outer side surface of the bracelet body as the optical sensor assembly 100. The gravity sensor 300 may be disposed inside the bracelet body, and the acceleration information detected by the gravity sensor may be transmitted to the processing chip 200.
The processing chip 200 is arranged on the bracelet body and used for judging whether the illumination intensity and the acceleration information meet alarm conditions; if yes, generating alarm information; the processing chip 200 can judge the motion state of the arm of wearing the bracelet according to the acceleration information and the illumination intensity of the detected bracelet, specifically, the alarm condition refers to the acceleration information and the illumination intensity that the motion state of the arm corresponds when the user falls down, and if the preset condition is met, the alarm condition can be judged to be used for falling down, and if the preset condition is not met, the alarm information does not need to be generated.
As a preferred embodiment, the processing chip is specifically a chip that determines that the illumination intensity and the acceleration information meet the alarm condition when an absolute value of a variation of the acceleration information within a preset time is greater than a first preset value and a variation of the illumination intensity is smaller than a second preset value. Accordingly, the alarm condition mentioned in this embodiment may be that an absolute value of a variation of the acceleration information within a preset time is greater than a first preset value, and a variation of the illumination intensity within the same preset time is less than a second preset value. The absolute value of the variation of the acceleration information and the variation of the illumination intensity determined here are the variations corresponding to the same time period, and the time period is a corresponding time length within a preset time. It should be noted that, in the present embodiment, the processing chip 200 of the default smart bracelet continuously receives the illumination intensity detected by the optical sensor assembly 100 and the acceleration information detected by the gravity sensor, and the following operations exist:
the method comprises the following steps: judging whether the difference value between the current received illumination intensity A1 and the illumination intensity A2 before the preset time period is smaller than a second preset value or not to obtain a first judgment result;
step two: judging whether the absolute value of the difference between the currently received acceleration information B1 and the acceleration information B2 before the preset time period is larger than a first preset value or not to obtain a second judgment result;
step three: judging whether the first judgment result and the second judgment result are both yes; if yes, the alarm condition is judged to be met, and alarm information can be generated.
When a wearer of the smart bracelet falls down, the arm wearing the smart bracelet suddenly loses weight and contacts with the ground, and the acceleration of the smart bracelet suddenly changes when the wearer of the smart bracelet falls down, namely, the smart bracelet is weightless and overweight; when the intelligent bracelet wearer fell down, the arm can support therefore intelligent bracelet surrounding environment's on ground illumination intensity can be by strong weak, and illumination intensity can diminish suddenly promptly. Based on the analysis of the posture of the arm when the human body falls, the following judgment can be made: if the absolute value of the variation of the acceleration information is greater than the first preset value within the preset time, and the variation of the illumination intensity is less than the second preset value within the same preset time, the intelligent bracelet wearer can be judged to fall down.
In the embodiment provided by the invention, the acceleration information of the starting time and the ending time of the time period corresponding to the preset time is compared with the illumination intensity. The above process is illustrated as a specific example: the first preset value is set to be 8 m/s square, the second preset value is-100 lux, and the preset time is set to be 0.5 s. The intensity of light received at the current time (10 th second) was 50 lux, and the acceleration information was 10 m/sec square. At this time, it is determined that the time before 0.5 second, that is, the intensity of light received at 9.5 th second is 300 lux, and the acceleration information is 0 m/s square. Within 0.5 second, the absolute value of the variation of the acceleration information is 10 m/s square, and the variation of the illumination intensity is-250 lux, so that the alarm condition is met. It should be noted that, the variation mentioned in this embodiment is obtained by subtracting the data detected at the time earlier than the preset time from the data detected at the current time, and the acceleration information may take the gravity direction as the positive direction. Falling down the arm and ground contact at intelligence bracelet wearer, the illumination intensity of arm can reduce, therefore first default is the burden.
As another preferred embodiment, the smart bracelet may further include:
the communication component is connected with the processing chip and used for dialing a preset telephone number when the alarm information is detected; with the voice broadcast module that processing chip connects for when detecting report first preset pronunciation of message. When the intelligent bracelet judges that the user falls down, preset telephone numbers including an alarm or emergency call and a call of an emergency contact person can be dialed. The voice broadcasting module can play first preset voice through the voice broadcasting module when a user falls down, and the first preset voice can comprise contents seeking help to passers-by.
When the intelligent bracelet person of wearing fell down, the arm of wearing intelligent bracelet can weightlessness suddenly and with ground contact, based on the motion analysis of limbs when falling down to the human, this embodiment is through setting up optical sensor subassembly and gravity sensor on intelligent bracelet, detects the motion state when the arm of wearing intelligent bracelet accords with to fall down. When a wearer falls down, the smart bracelet suddenly loses weight, so that acceleration information detected by the gravity sensor changes to a certain extent; because the arm will contact with the ground, the illumination intensity detected by the light sensor assembly will also change. The embodiment judges whether the arm wearing the intelligent bracelet accords with the motion state when falling according to the change condition of the illumination intensity detected by the optical sensor assembly in the preset time and the change condition of the acceleration information detected by the gravity sensor in the preset time, so that alarm information can be sent for timely rescue. This application can judge whether intelligent bracelet person of wearing falls down, initiatively sends alarm information when intelligent bracelet person of wearing falls down, strives for the best rescue opportunity.
