Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to a water meter power supply device based on hydraulic pressure difference. Background Art

[0002] Existing remote water meter reading systems rely on the water meter's 485 bus, DTU communication modules, centralized data collectors, and other devices. These communicate with a remote monitoring system via the RS485 bus, transmitting processed data to the remote monitoring system. This enables the transmission, real-time recording, and monitoring of water meter readings, simplifying meter reading and improving efficiency. This remote water meter reading system requires a stable power supply. For locations without access to electricity or a stable power supply, manual meter readings over a specific timeframe are typically required using DC batteries or handheld readers. This renders remote meter reading and data monitoring impossible, wasting manpower and resources.

[0003] Currently, due to factors such as limited installation areas, our company's remote water meters have about 600 sites without power company meters for power supply. The power supply sources include internal electricity of the property, electricity without meters (electricity with electricity but no meter), and user electricity, which are difficult to manage and control, and may cause safety hazards and economic disputes. Therefore, the present invention proposes a water meter power supply device based on hydraulic pressure difference. Summary of the Invention
