Power Design Based On The Human Foot Movement

The modern war needs to rely on a large number of information technology equipment to improve the combat capability of soldiers. With the progress of technology, the functions of these information equipment gradually increased, the power consumption is also gradually increased. The current commonly used storage batteries are small capacity, short life time and high weight etc. Has become one of the important factors that restrict the development of equipment. Therefore, it is very necessary to study the portable power supply which can be used in equipment at any time. This article mainly aims at the demand of individual information equipment in the war. Designed a power supply structure based on the human body movement energy. Provide certain technical support for improving the level of equipment of the soldiers under the condition of information war.Based on the analysis of human energy generation principle and the technical approach. Proposed electromagnetic induction generation technology solutions the use of foot motion energy power, and the power structure and circuit design. Structure, through the lever and the rack fixedly,the kinetic energy of the foot up and down movement is converted into rotational movement of the gear. And then the gear pass kinetic energy to the pawl, turn the ratchet inertial rotation, so as to drive magnet the cutting magnetic induction line produces alternating current. Circuit, according to the requirement of power supply, the main design of the rectifier circuit, charge and discharge protection circuit, a voltage conversion circuit, a display circuit unit. In the direct power supply at the same time, the remaining power can be stored in the lithium battery, to ensure the continued use of equipment. Finally, the principle test is carried out. The results show that the system can meet the design requirements.
