Embodiment 1

[0022] A mechanical energy harvesting system for energy harvesting when trains and cars brake, including:

[0023] The single-chip microcomputer control module, the energy conversion module, the electric energy storage module and the power supply module, the single-chip microcomputer control module monitors the operation of the vehicle, and judges whether the vehicle is running normally or braking. During normal operation, the single-chip microcomputer has no output. , the single-chip microcomputer control module controls the current of different sizes to flow into the main excitation pole of the energy conversion module, adjusts the amplitude of energy conversion, reduces the loss of the vehicle braking device, and improves vehicle performance. The energy conversion module is a small DC generator or a small AC generator machine, the electric energy storage module is the battery charging circuit and the battery, the power supply module is the power supply for the single-chip mi...

Embodiment 2

[0035] The existing low-power mechanical generator is refitted, and the main terminal of the excitation is left to be controlled by the drive module of the single-chip microcomputer. The LR160-708 9-tube low-power generator can be refitted to obtain the energy conversion module required by the system. .

Embodiment 3

[0037] The electric energy storage module can preferably be an ES-D (1500W) series charger or a similar charger and a 46B24LR12V45AH battery or a battery with a larger capacity.

Abstract

The invention discloses a mechanical energy collecting system and a method thereof. The mechanical energy collecting system and the method there of are used for collecting the mechanical energy lost by the braking of a train and an automobile for secondary use. According to the mechanical energy collecting system, a single chip microcomputer is used for monitoring the vehicle running situation and judging whether a vehicle runs or brakes normally, if the vehicle runs normally, the single chip microcomputer has no output, and the vehicle runs normally. When the vehicle brakes, a control module of the single chip microcomputer detects the real-time speed of the vehicle, latter driving and electrical controlling of the single chip microcomputer is adjusted, an excitation main pole is controlled, and the amplitude of converting the mechanical energy into the electric energy is adjusted; at this time, a certain brake effect for the vehicle is achieved through electromagnetic torque, the damage caused by mechanical brake to the vehicle mechanical structure is decreased, and the brake performance of the vehicle is improved. The collected mechanical energy is stored in a battery, and the energy in the battery is supplied to auxiliary vehicle start, an electrical appliance for the vehicle and the control module of the single chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of energy machinery, in particular to a mechanical energy collection system and a method thereof. Background technique [0002] Most of the existing trains, automobiles or automobiles are braked by mechanical braking. These methods have high requirements on braking equipment, and high-performance braking equipment requires a huge investment in manufacturing and maintenance. At the same time, in the process of continuous braking of the machine, the loss of the mechanical structure is huge, the reliability decreases after long-term use, the cost of replacement and maintenance is high, and the instability and unsafety of operation are added. In addition, during the braking process, most of the mechanical energy is converted into heat and dissipated, which makes the kinetic energy of the original motion wasted, which is not environmentally friendly and economical. [0003] Under the control of the single-chip m...
