Self-powered vehicle-mounted positioning tracking and alarming device

Abstract

The invention relates to a self-powered vehicle-mounted positioning tracking and alarming device, and belongs to the automobile electronic technical field. An ear plate is arranged on each of the left side wall and the right side wall of each of an upper shell and a lower shell, limiting surfaces are arranged on each of the front side wall end and the rear side wall end of each of the upper shell and the lower shell, and a guide groove is arranged on each of the middle parts of the front side wall and the rear side wall of each of the upper shell and the lower shell; the lower shell is provided with an acceleration sensor and a circuit board provided with a transmitting unit; metal substrates are connected between the upper ear plates and the lower ear plates at the left side and the right side in a pressing manner, the middle part and the end part of each metal substrate are respectively provided with a first electromagnetic unit and a second electromagnetic unit, and piezoelectric wafers are pasted at two sides of each metal substrate; third electromagnetic units are arranged above the first electromagnetic unit and the second electromagnetic unit of the upper shell and below the first electromagnetic unit and the second electromagnetic unit of the lower shell; each electromagnetic unit is composed of a magnet and a coil; the upper end and the lower end of a floating plate inlaid with a fourth coil are respectively placed in the upper guide groove and the lower guide groove, and springs are connected between the floating plate and the upper shell and between the floating plate and the lower shell in a pressing manner. The self-powered vehicle-mounted positioning tracking and alarming device has the advantages and characteristics: the device is self-supported with energy, can be used as an independent component to be buried in a body hidden part, and is safe and reliable; the environmental adaptation and power generation capacities of power generation components are strong, the effective frequency band is wide, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a self-powered vehicle positioning tracking and alarm device. Background technique [0002] Vehicle positioning and navigation systems have been widely used in real life. However, the existing positioning device has a single function, and mainly aims at guiding the driver to the destination. From a practical point of view, the vehicle positioning and tracking system can also realize functions such as real-time monitoring and reporting of vehicle speed, automatic alarm of major traffic accidents, or tracking of vehicle theft. The positioning system will not continue to work; in addition, the existing positioning systems are all external, can be closed or destroyed artificially, and cannot be used for speed monitoring and theft tracking. Therefore, in order to expand the functions and practicability of the positioning system, it is first necessary to so...
