Provided is a passive wireless magnetic field characteristic sensing tag and system, and a magnetic field quantity acquisition method, which integrates a passive magnetic field quantity sensor in a passive electronic tag and cooperates with a reader and a host computer to build a magnetic field sensing system, so as to realize high-precision and high-intelligence monitoring of the magnetic field quantity.

Passive wireless magnetic field characteristic sensing tag and system, and magnetic field quantity acquisition method

An ultrathin LED light engine () comprises a protective cover (), a driving circuit board (), an aluminum substrate () and at least one LED module (). A double-sided high-viscosity heat conducting plate () covers the first surface of the aluminum substrate () to fix the driving circuit board (); the at least one LED module () is fixed on the first surface and insulated from the aluminum substrate () by means of an insulating layer () on the first surface; a conductive circuit for electrically connecting the at least one LED module () and the driving circuit board () is arranged on the insulating layer (); and the size of the aluminum substrate () at least at the local peripheral outer area is greater than that of the driving circuit board (), so that the double-sided high-viscosity heat conducting plate () on the first surface at least locally fixes the protective cover (). The LED light engine () realizes ultrathin design and built-in integration of drive and control devices, and realizes heat conduction and fixation of the PCB and the protective cover by using a double-sided high-viscosity film.

A signal synchronizing system includes comparison circuitry and control circuitry. The comparison circuitry compares a synchronizing signal with an input signal to generate a comparison result. The control circuitry adjusts the synchronizing signal into a range that is determined by the input signal, and controls the range according to the comparison result.
