Abstract
An integrated rechargeable battery device is used for a monitoring and early warning system. A battery can simultaneously collect radio frequency energy and heat, radio frequency signal collection can include selection of various frequencies, a radio frequency power detecting circuit is used for selecting matched signals to collect energy, and a radio frequency signal collection module comprises a radio frequency power detection circuit, a matched circuit and a three-level booster circuit. According to the integrated rechargeable battery device, an improved CMOS (complementary metal oxide semiconductor) cross coupling full wave rectifier circuit replaces a traditional Schottky diode rectifier circuit, so that output direct current loss after rectification of a small signal is reduced. The booster circuit is controlled by an improved booster pump circuit by the aid of five-level CP (computer program) pulse, so that the shortcoming that a traditional booster circuit needs to be powered by an external power supply, is high in power consumption and the like is overcome, and the output efficiency of the whole circuit is improved. The requirement on low current consumption is met by the aid of a switch control circuit comprising a voltage detector and a switch transistor. Compared with a traditional charging device, the integrated rechargeable battery device is more easily integrated by the aid of a passive and active mixed electric energy storage and management module.
