From the development of the current intelligent wearing products, the enthusiasm degree of foreign countries on the intelligent wearing products is higher, and enterprises such as Sony, Samsung, Naike and the like have also provided similar products, for example, NIKE sports shoes can record the number of steps of people going out; the Googleglass Google glasses can record all people see in daily life; the CloudRing smart necklace can record the body functions and the like.

The intelligent wearable product with the corresponding mobile phone APP mainly uses the Bluetooth technology as a communication mode. As the Bluetooth wireless communication module is used as a developing wireless communication standard, barriers such as walls and briefcases can be penetrated among information equipment through a uniform short-range wireless link, and the Bluetooth technology is widely applied to the field of intelligent communication terminals.

Currently, the bluetooth version of practical applications has been updated to the 5.1 version. The maximum transmission rate can reach 24 Mbps. Theoretically, the communication distance can reach 300 meters. Meanwhile, Bluetooth 5.1 achieves ultra-low power consumption, and the power consumption of one hour is only 1/3 of Wi-Fi. In addition, the indoor communication system has stronger anti-interference capability in a room with a plurality of communication terminals, and particularly for Wi-Fi and LTE signals, signal blockage in a limited space can be avoided to a certain extent. The output power of the Bluetooth product is only 1mW, only a very small part of the output power is absorbed by a human body, and compared with other communication technologies, the Bluetooth product has high safety.

Fig. 2 is a block diagram of a hardware structure of a motion energy collection module, which mainly comprises a motion energy collector, a rectification circuit and an energy storage and conditioning circuit.

In the motion energy acquisition module, a single component of the motion energy acquisition device consists of a vacuum hose, a cylindrical magnet, a magnetic bead and a copper wire. The polarities of the magnets at the two ends of the vacuum tube are opposite to those of the magnetic beads, so that a magnetic suspension structure is formed. In the motion process of a human body, the magnetic beads bounce back and forth in the vacuum tube, and magnetic lines of force between the magnetic beads and the magnet continuously cut the copper wires wound on the vacuum hose. According to the theory of electromagnetism, induced current is generated on the copper wire. The plurality of moving energy collector parts are connected in parallel, and the induced current on the copper wire is very considerable. Then, the copper wire is connected with a rectifying circuit to rectify the generated alternating current into direct current. The direct current electric energy generated by rectification is subjected to processes of clutter removal, impedance matching and the like by an energy storage and conditioning circuit. And finally, part of the energy obtained by human body movement supplies power to the sensor and the radio frequency module, and the other part of the energy supplies power to the miniature lithium battery.

Theoretical basis of motion energy harvester:

the vacuum hose is fully wound with copper wires, and the magnetic flux in the unit cross section of the vacuum hose is as follows:

for effective magnetic induction, r is the vacuum hose radius. When the magnetic beads in the vacuum tube start to jump, induced electromotive force is generated at the two ends of the copper wire, namely the induced electromotive force is：

Ideally, the magnetic linkage Ψ is N Φ, and N is the number of turns of the copper wire wound around the hose. Then the above formula can be written as:

the generated induced electromotive force is electric energy obtained by converting mechanical energy of motion. It can be known that the cross-sectional area of the hose and the number of turns of the copper wire have a great influence on the electric energy obtained by conversion. However, the size of the hose is not too large, the number of winding turns of the copper wire is more, which means that the copper wire needs to be thinner, but the thinner copper wire will cause the impedance of the collector to be increased, the loss is larger, and the conversion efficiency is reduced. Therefore, the thickness of the hose and the winding number of the copper wire need to be adjusted according to actual conditions.

A rectifier circuit: the micro-patch type resonant circuit is composed of a micro-patch rectifier bridge, a resonant matching capacitor and an RC filter circuit. The resulting irregular alternating current is rectified to direct current with a small fraction of the alternating current component.

Energy storage and conditioning circuitry: chip ADP5091, manufactured by Asia Deno semiconductors, was used as the master chip. The device is provided with necessary resistors, capacitors and inductors, the electric energy obtained by the movement energy collector can be stored in the electrolytic capacitor, and the electrolytic capacitor provides a stable 3.3V power supply for the sensor and the Bluetooth module intermittently through the chip ADP 5091. Meanwhile, the chip is also connected with a miniature lithium battery, and the lithium battery is charged when residual energy exists. When using the adapter or the precious intelligent protective equipment of connecting that charges, also can be through giving lithium cell after the chip steady voltage charges, or drive miniature vibrating motor.

Fig. 5 is a flowchart of a bluetooth communication module and mobile phone software, after the bluetooth communication module is powered on, the module is initialized, then the sensor is initialized, the sensor circularly waits for data information to be sent back, 3 items of data information are received, the 3 items of data information are integrated and coded into a frame structure fixed by a bluetooth 5.1 transmission protocol, and finally the data information is sent to a mobile phone APP end. When the mobile phone end receives data information, the information is decoded at first, and then the obtained information is converted into an actual heart rate numerical value, a calorie consumption numerical value and a temperature numerical value according to a corresponding formula and is stored. The resulting values are then printed in the corresponding coordinate axes and wired. And analyzing the data after the movement is finished, judging whether each numerical value is within a normal range, and giving a movement suggestion and related pushing under the networking condition.
