Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] Such as figure 1 As shown, a behavior monitoring wristband powered by a switching power supply of the present invention is ring-shaped as a whole, and its outer surface is covered with EVA material. The instrument panel is embedded in the ring, and the instrument panel is connected to the two ends of the instrument panel by splicing. The formed chain belt constitutes a ring-shaped main body; a GPRS communication module, a micro-vibrator and an audio pla...

The invention provides a behavior monitoring bracelet powered up by a switch power supply. The whole behavior monitoring bracelet is in an annular shape, the outer surface of the behavior monitoring bracelet is coated by an EVA (Ethylene Vinyl Acetate) material, an instrument panel is embedded in the middle position in the annular shape, and an annular main body is formed by the instrument panel and chain belts which are connected to two ends of the instrument panel by splicing; a GPRS (General Packet Radio Service) communication module, a micro vibrator and an audio player are embedded in the instrument panel; the instrument panel also comprises a three-shaft gravity acceleration sensor, a gyroscope and a DSP (Digital Signal Processor), and the DSP comprises an integrator and a filtration and optimization module; the three-shaft gravity acceleration sensor is used for outputting acceleration data information in an X axis, a Y axis and a Z axis, the gyroscope is used for outputting angular rate information of a rotating angle of a human body, the integrator of the DSP is used for integrating the angular rate information output by the gyroscope, obtaining a relative rotating angle of the human body and outputting motion states according to the relative rotating angle, and the motion states comprise a moving state, a tumbling state and a static state.
Description
technical field [0001] The invention relates to the field of electronics, in particular to a behavior monitoring bracelet powered by a switching power supply. Background technique [0002] With the aggravation of the aging problem and the acceleration of people's work pace, more and more elderly people need to live independently. Their children are either in other places, or they have no time to take care of the elderly. There will be accidents in the diet and daily life of the elderly, such as falls, Unexpected children do not know, often resulting in serious consequences. [0003] How to send the status of the elderly to their children in real time when an accident occurs is a problem that needs to be solved urgently. Contents of the invention [0004] The invention proposes a behavior monitoring wristband powered by a switching power supply, which solves the problem of how to send the unexpected situation of the elderly to the mobile phone terminal of the children in t...
