Technical Field

The application relates to the field of metering instruments, in particular to a water meter capacitance source supply device, system and method based on nanometer friction.

Background

The intelligent water meter system is used as a representative product of the current intelligent process, and the application range is more and more extensive. With the development of high-end technology industrialization, research on an intelligent water meter system is deepened gradually, but the safety problems caused by factors such as large power consumption and batteries still exist. Triboelectricity is one of the most common phenomena in nature, and can be used for combing hair, dressing, walking and driving. Triboelectricity is difficult to collect and use and is therefore often overlooked.

The existing water meter can only obtain electric energy by depending on a battery because of no continuous external electric energy supply, most of the current popular power supply methods on the market directly use a lithium battery as a power supply of the meter, and the few power supply methods realize power supply by the combination of a micro generator and the battery; therefore, the terminal water meter instrument can work for a long time without interruption only by ensuring extremely low power consumption in the operation process.

However, the need to replace the battery or scrap the water meter after the power is exhausted presents a significant problem for after-market service. In the existing water meter installation environment, because the installation environment condition is severe, the service life of a battery of the water meter is shortened, and therefore the replacement frequency is increased.
