AI Technical Summary

Technical Problem

The power supply system of IoT turbine flow meters relies on external energy, resulting in short battery life, limited charging methods, and a lack of dynamic adaptability in the power generation system, making it unable to provide stable power supply under complex operating conditions, which affects the continuity and reliability of flow data.

Method used

The design employs a coil assembly with separate operating and standby areas. By dynamically increasing the number of coils in the operating area through a driving component, combined with a supercapacitor bank and an energy storage management circuit board, dynamic adjustment of power generation and redundant protection of the power supply system are achieved, ensuring stable power supply under different fluid flow rate conditions.

Benefits of technology

It achieves stability and adaptability of self-generated power, reduces operation and maintenance costs, ensures long-term stable operation of the flow meter under complex working conditions, and avoids energy waste and data loss.

Abstract

The invention relates to the technical field of flow meters, and discloses a self-power-generation internet-of-things turbine flow meter and a using method thereof. The self-power-generation internet-of-things turbine flow meter comprises a sensor mechanism, a converter mechanism and a power generation coil mechanism; the sensor mechanism comprises a pipe body and an impeller assembly installed in the pipe body. The converter mechanism comprises a converter shell and a probe which is correspondingly matched with the impeller assembly for metering; the power generation coil mechanism comprises a coil jacket and a power panel; a plurality of power generation cavities distributed in the circumferential direction are formed in the coil clamping sleeve. The power generation coil mechanism adopts the coil assembly design that a use area and a standby area are separated, the number of coils in the use area can be dynamically increased through a driving piece, and when the fluid flow speed is low and power generation power is insufficient, the standby coil assembly can be rapidly called to participate in power generation, and power supply stability is ensured; and in a full-load power generation state, energy waste can be avoided by reasonably distributing the working number of the coils, and the power generation requirements of working conditions with different fluid flow speeds are met.
