However, the self-generating positioning shoes have low power and high energy consumption, and are not beneficial to long-term use. The self-generating positioning shoe uses the unbalanced rotor, the human body walks one step, and the rotor rotates one circle. According to the electromagnetic induction law, the induced electromotive force generated by the conductor cutting magnetic induction lines is related to the moving speed of the conductor, and the faster the cutting speed of the magnetic induction lines is, the more block the voltage generated by the conductor is. Since an ampere force is generated when a conductor in a magnetic field generates a current, and the ampere force is increased when the current is increased, the ampere force is generated when the unbalanced rotor rotates to prevent the rotor from rotating, and the rotor rotation is generated by the inertia of the rotor, no external force is applied to maintain the rotor rotation, so that the rotor rotation speed is reduced, the generated electromotive force is reduced, and the power generation is prevented. And GPS and BDS bimodulus location is all-weather operation, and the electric energy consumption is big, also is transmitting data when the object does not move, and is extravagant very much the energy.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The invention provides a self-generating device which can capture energy generated by sole pressing when a human body walks and convert the energy into electric energy. The characteristic that the sole of the walking foot of the human body is stepped is utilized to convert the mechanical energy buffered and lifted downwards into electric energy and store the electric energy; furthermore, the self-generating device is used as a power supply, so that the low-power-consumption positioning equipment is provided, and the continuous use of the equipment under limited energy is ensured.
A large amount of energy can be obtained by applying work when the walking heels of the human body are grounded and buffered. Assuming that a person has a weight of 60Kg, the weight of the person is about 588N, the weight of the person on one foot is about one-half of the total weight, about 294N, and if the cushioning distance is 1 cm when the person lands on the heel, the person's heel applies work to the outside about 2.94J. Therefore, the human body can generate a large amount of energy when being stepped on during walking, and if the energy can be collected, a good energy source can be obtained.
According to the dynamic and static conditions of the human body and the collection condition of the energy, the data transmission frequency of the GPS and BDS modules is controlled, the energy is prevented from being wasted, and the cruising ability of the integrated equipment is ensured. Unlike vehicle-mounted GPS, the speed of human body walking is not fast, and the real-time positioning of human body is not very necessary, so that the positioning information is only required to be sent once at a certain time interval. When the human body walks, the equipment is in an energy collecting state, when the condition that the energy storage degree meets the requirement during data transmission is detected, the positioning information of the GPS and the BDS is transmitted outwards, and after the transmission is finished, the equipment is in a dormant state, so that the energy consumption is reduced. When the human body stops moving, no energy is input at the moment, and the requirement of repeatedly sending positioning information to the same position is avoided, so that the equipment is in a deep sleep state, and unnecessary energy consumption is reduced.
The invention provides a self-generating device utilizing human body walking, which mainly comprises a treading transmission device, a speed reducer, a generator and an AC-DC conversion circuit, as shown in figures 2 and 3. The stepping transmission device is used for converting downward displacement when the heel is grounded into rotation of the Z-shaped transmission shaft 6. The speed reducer 8 is used for amplifying the rotating speed. The generator motor 9 is used to generate electric power. AC-DC converts alternating current produced by the generator into direct current.
The trampling transmission device comprises a trampling block 1, a limiting frame (2), a magnet A (3), a magnet B (4) and a Z-shaped transmission shaft (6).
The treading block 1 and the limiting frame (2) are both made of hard plastic.
The limiting frame (2) is a cuboid frame with one open end; the size of the stepping block 1 is slightly smaller than the size of the inner aperture of the limiting frame (2). The treading block 1 can be freely put in and taken out from the limiting frame (2). The bottom of the stepping block 1 is fixedly connected with a magnet A, the bottom of the limiting frame (2) is fixedly connected with a magnet B, the placement mode is shown in figure 2, wherein the same magnetic poles of the magnet A3 and the magnet B4 are opposite, and repulsion is generated. The stepping block 1 is placed into the limiting frame (2) in a mode that the magnet A3 faces downwards, the stepping block 1 is in a floating state due to repulsion force generated by the magnet, the stepping block 1 is pressed forcibly, the stepping block 1 can enter the limiting frame (2), and the stepping block 1 is released slowly and can return to the original position. A treading block groove 5 with a certain width is arranged on one side surface of the treading block 1; and a transmission shaft movable groove (7) with the same width is formed in the limiting frame (2) at the position opposite to the treading block groove (5), and when the treading block (1) moves downwards, the Z-shaped transmission shaft (6) is not blocked from moving in the width direction.
One end of the Z-shaped transmission shaft 6 is placed in the treading block groove 5 and can move in the width direction of the treading block groove 5;
the other end of the Z-shaped transmission shaft 6 is connected with an output port of a speed reducer 8; the input port of the speed reducer 8 is connected with the rotor of the generator 9.
And finally, the limiting frame (2), the Z-shaped transmission shaft 6, the speed reducer 8 and the generator 9 are arranged at the relative positions shown in figures 2 and 3 and fixed at the heel part of the shoe shown in figure 4, the heel must be capable of stepping on the stepping block 1, and the parts 2,8 and 9 cannot be displaced relatively. The specific placement positions of the structures can be adjusted according to the shape of the actual shoe, as long as the heel can be stepped on the tread block 1.
The working principle of the self-generating device is as follows:
when the stepping block 1 is stepped on, one end of the Z-shaped transmission shaft 6 in the groove 5 of the stepping block moves downwards along with the stepping block 1, and meanwhile, the end moves in the groove 5 of the stepping block along the width direction, so that the end of the Z-shaped transmission shaft 6 generates circular arc motion, the other end can be driven to rotate by taking the output port of the speed reducer 8 as the center, and the speed reducer 8 and the generator 9 are driven to rotate. One end of the Z-shaped transmission shaft 6 can move freely without being blocked because the treading point groove 5 has enough moving width. When the treading block 1 reaches the lowest point of activity, the Z-shaped transmission shaft 6 stops moving, and the speed reducer 8 and the generator 9 stop rotating. During the downward movement of the stepping block 1, the generator 9 will generate a voltage to be output from the lead 10, and the voltage generated at this time is defined as positive.
When the stepping block 1 is released, the stepping block 1 moves upwards under the action of the repulsive force between the magnet A3 and the magnet B4, and drives one end of the Z-shaped transmission shaft 6 to move upwards, and meanwhile, the end also moves transversely in the stepping block groove 5, so that the end of the Z-shaped transmission shaft 6 rotates reversely, and the other end of the Z-shaped transmission shaft 6 rotates around the output port of the speed reducer 8 and drives the speed reducer 8 to rotate reversely with the generator 9. When the treading block 1 reaches the highest point of activity, the Z-shaped transmission shaft 6 stops moving, and the speed reducer 8 and the generator 9 stop rotating. During the upward movement of the treading block 1, the generator 9 will generate a reverse voltage to be output from the lead 10.
The AC-DC module converts the alternating current output by the generator 10 into direct current output. A single-phase rectifying circuit is formed by 4 diodes, alternating current is directly input into the rectifying circuit, and finally direct current voltage stably output by a filter capacitor is added to an output port of the rectifying circuit.
In addition, experiments show that the speed of the heel and the toe of the human body is far higher than that of the sole of the foot when the human body walks, but the power generation device is easier to mount at the heel of the foot in consideration of the wearable factor, and the acceleration of the heel of the human body is slightly larger than that of the toe of the human body, so that the mechanical energy power generation device can be mounted at the heel of the foot.
The invention also provides a wireless locator based on the self-generating device, which comprises a power supply unit and a locating communication unit besides the self-generating device. The two units are reasonably arranged on the sole or other parts of the shoe body according to the style of the shoe to realize the functions of power supply and positioning communication.
The power supply unit is composed of a voltage stabilizing module and an energy storage module, as shown in fig. 1. The voltage stabilizing module is mainly used for stabilizing the voltage output by the power generation module at 3.3V. An AMS1117-3.3 chip is used to form a typical 3.3V voltage regulator circuit. And the output of the stabilized voltage is connected to a power supply access interface of the positioning communication module and a power supply input interface of the energy storage circuit through a diode. The energy storage circuit stores electric energy in the lithium battery. When the voltage output by the power generation module is smaller than the voltage of the energy storage circuit, the energy storage circuit is automatically switched to supply power.
The positioning communication unit comprises a low-power-consumption singlechip MCU, a GPS/BDS positioning module, a GPRS wireless communication module and a motion sensor, and realizes GPS/BDS positioning, positioning information sending, human body motion condition detection and power consumption control.
The power consumption singlechip MCU carries out data transmission with low-power consumption GPS/BDS orientation module through hardware interface, and the singlechip controls orientation module to read positioning information according to the communication protocol that orientation module provided. The GPS/BDS positioning module antenna uses a flexible antenna, and the antenna is buried in the shoe upper and the shoe lace to ensure the receiving of the model. The low-power consumption singlechip carries out data transmission with low-power consumption GPRS wireless communication module through hardware interface, and the singlechip transmits the locating data to the server with the communication protocol of GPRS wireless communication module. The motion sensor detects the motion condition of the human body. The single chip microcomputer judges the current motion state of the human body according to the data collected by the motion sensor, and when the current motion state is judged to be static, the single chip microcomputer configures all equipment into a low power consumption mode and also enters a deep sleep state to save electric energy. When the current motion state is judged, the single chip microcomputer uses an ADC sensor carried by the single chip microcomputer to acquire the voltage condition of the power supply at regular time, when the voltage meets the minimum requirements for acquiring and sending positioning information, the single chip microcomputer sends a positioning information reading instruction to the GPS/BDS positioning module to acquire positioning data, when the voltage does not meet the minimum requirements for acquiring and sending the positioning information, the single chip microcomputer continues to set the GPS/BDS positioning module and the GPRS module into a low-power-consumption mode, the electric energy waste is reduced, the electric energy is continuously stored, and the positioning and data uploading are not performed until the voltage meets the minimum requirements for acquiring and sending the positioning information. The normal operation and the endurance capacity of the equipment are ensured.
Through the specific implementation mode, more electric energy can be acquired to a great extent, the waste of the electric energy can be reduced, the cruising ability is ensured, and finally the positioner with the self-generating function is realized.
The invention is beneficial to the guardian to determine the positions of the old and the child. At present, old people and children often go out to go out or stroll shopping malls, and get crowded places in places with complex environments, so that the old people or the children are prone to getting lost. The guardian can timely acquire the position information of the lost old man or the lost child by utilizing the positioning function after finding, and accidents are avoided.
The shape of the invention is the same as that of a common sports shoe, and internal power generation and positioning equipment is not easy to find. The shape of the invention is the same as that of a common sports shoe, and the modules of power generation, positioning communication and the like are all hidden in the sole. Unlike positioning devices such as positioning watches, the present invention does not visually reveal internal device information.
