Abstract

The invention discloses a wireless power supply circuit and a wireless power supply ultrasonic metering device. The circuit comprises a collection antenna, a matching rectification circuit, a power supply management module and an energy storage module, the collection antenna is connected with the input end of the matching rectification circuit, the output end of the matching rectification circuitis connected with the input end of the power management module, the first output end of the power management module is connected with the energy storage module, and the second output end of the powermanagement module is connected with a first load. The collection antenna is used for receiving electromagnetic waves and transmitting the electromagnetic waves to the matching rectification circuit; the matching rectification circuit is used for converting the electromagnetic waves into direct-current voltage; the power supply management module is used for charging the energy storage module and supplying power to the first load; the power supply management module is also used for receiving the power supply voltage output by the energy storage module and supplying power to the first load through the power supply voltage. The electromagnetic waves are collected and converted into electric energy to charge the energy storage module and supply power to the load, so that the load can stably operate for a long time.

Description

Technical field [0001] The invention relates to the field of circuit electronics, in particular to a wireless power supply circuit and a wireless power supply ultrasonic metering device. Background technique [0002] With the continuous development of Internet of Things technology, various metering devices are constantly being updated. For example, traditional mechanical water meters have been gradually replaced by electronic water meters. At present, the popular electronic water meters in the market are usually ultrasonic water meters, and their power supply methods are mainly battery-powered and self-powered. The battery power supply method generally uses a disposable lithium sub-battery to power the ultrasonic water meter, and the battery needs to be replaced after the battery is exhausted. The self-powering method uses piezoelectric transducers to convert the water pressure when water flows into electrical energy for storage and use. [0003] Among the existing mainstream pow...
