Traffic early warning system achieving piezoelectric power generation through vibration of deceleration strips and method for achieving piezoelectric power generation through vibration of deceleration strips

Abstract

The invention provides a traffic early warning system achieving piezoelectric power generation through vibration of deceleration strips and a method for achieving piezoelectric power generation through vibration of the deceleration strips. Vibration energy generated when a vehicle passes through the road deceleration strips is converted into electricity energy through a piezoelectric energy capturing device, and the electricity energy is used for the traffic early warning system attached to the deceleration strips or stored in an energy storage device. The system comprises the piezoelectric energy capturing device, a rectifier circuit, a control circuit, a storage circuit, a safety warning device and the energy storage device, the piezoelectric energy capturing device is connected with the rectifier circuit and the control circuit, and the rectifier circuit and the storage circuit are connected with the safety warning device and the energy storage device. The traffic early warning system is not limited by natural conditions, can effectively utilize vibration generated when the vehicle passes through the deceleration strips and has the advantages of being simple in structure, free of electromagnetic pollution, economical in energy, environmentally friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of road pressure power generation, and in particular relates to a traffic early warning system and a method thereof using vibration piezoelectric power generation of speed bumps. Background technique [0002] At present, the use of flashing signs in road traffic facilities such as traffic lights, road traffic signs, and road traffic markings has gradually become a development trend. It can effectively reduce traffic safety hazards in low-visibility road conditions such as smog and rain. However, the use of external power supply for flashing traffic facilities will cause problems such as long-distance low-voltage power loss and increased costs, and its installation and normal use are restricted in remote mountainous areas or places where the road network in the suburbs cannot cover. Road transportation facilities equipped with rechargeable power sources have problems such as limited energy supply life and t...
