Abstract
The present invention relates to an intelligent energy management system and an energy management method for a passive radio frequency tag. Digital conversion is performed on the amplitude of a DC signal absorbed and rectified by an inductance coil antenna of the tag, by providing an intelligent energy management module. The input terminal of the intelligent energy management module is respectively connected to a power supply voltage detection and judgment circuit and a demodulator circuit, and configured to judge the level of charge and enabling state of the tag; and the output terminal thereof is respectively connected to a discharge path, a bias current source and an analog circuit module, and configured to bring the analog circuit module into the optimal operating state according to the enabling state of the tag, or to turn-off/get dormant each analog circuit module thus to reduce power consumption of the tag and improve the sensitivity of the tag. Meanwhile, the intelligent energy management module may further control the discharge path to conduct control on discharge of charge at both ends of the antennas, so that the voltage withstanding performance of devices connected to an inductance coil antenna is reliably ensured.
