[0050] The specific working principle and process of this utility model are as follows:

[0051] The smart oxygen meter is installed on the oxygen delivery pipeline, and its overall operation is controlled by a single-chip microcomputer 16. The oxygen flow sensor 4 detects the oxygen flow rate and outputs an analog signal. The A / D converter in the data processing module 14 converts the analog signal into a digital signal, which is then transmitted to the single-chip microcomputer 16. The single-chip microcomputer 16 transmits the data to a microprocessor and memory for further processing and storage. The microprocessor processes the data, stores the results in the memory, and transmits them to the billing module 15. The billing unit in the billing module 15 calculates the oxygen flow rate data using a preset algorithm, and combines parameters such as usage time and unit price to generate a detailed fee list, which is stored in the billing storage unit.

The liquid crystal display and operation buttons are both electrically connected to the single chip microcomputer and controlled by the single chip microcomputer.

[0053] The early warning unit detects sensor failure, battery failure, charging failure, etc. Once a failure is detected, the system will immediately send an alarm message to the user through the display module 11 or the communication module 8.

[0054] The communication module 8 uses the oxygen flow data, cost calculation results and related data to transmit the processed data to a remote server or user terminal via a wireless network.

[0055] The terminals in this system can update data in various ways. A scheduled update mechanism can update data hourly, daily, or weekly, ensuring timely data synchronization. A billing update mechanism automatically triggers updates when a user reaches a certain oxygen usage or fee. Furthermore, an event-triggered update mechanism initiates an update upon detecting anomalies or specific events, ensuring data integrity and stable system operation.

[0056] During operation, if the network is interrupted, the data processing module's memory temporarily stores all important data locally through data compression and encryption. Once the network is restored, the system automatically detects and sequentially transmits the locally stored data to a remote server or user terminal, ensuring data integrity and continuity.

[0057] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and should be understood that the scope of protection of the present invention is not limited to such specific descriptions and embodiments. Those skilled in the art can, based on the technical teachings disclosed in this utility model, make various other specific variations and combinations that do not depart from the essence of the present invention, and such variations and combinations are still within the scope of protection of the present invention.
