[0002] With the deep integration of IoT technology and the sharing economy model, smart shared devices are increasingly being used in fields such as healthcare and leisure. In the shared oxygen service sector, existing technologies typically employ a mobile payment-based smart control scheme. Users scan a QR code with their mobile devices to trigger a device usage request. After cloud verification, a start command is sent to the device, initiating timekeeping and billing. This type of solution primarily relies on network communication to achieve remote monitoring of device status and a closed-loop payment system. Control signals are transmitted via a 4G module, and basic authentication mechanisms are used to ensure device access security.

[0003] However, existing technologies still face the dual challenges of communication security and state synchronization reliability in actual deployment. Traditional authentication mechanisms often use static keys or fixed tokens, which are vulnerable to replay attacks or man-in-the-middle attacks in open network environments. Due to factors such as network latency and packet loss, there may be state inconsistencies between cloud servers and terminal devices. Summary of the Invention

[0065] Furthermore, the control circuit of the shared oxygen inhalation zone machine reads control commands from the instruction register, generates corresponding drive voltage signals, and transmits them to the coil winding of the solenoid valve opening mechanism. Under the action of electromagnetic force, the solenoid valve opening mechanism overcomes the spring resistance and moves the valve core, so that the valve channel and the oxygen outlet form a connected path, and the oxygen outlet enters a smooth state.

[0066] S5.3 The shared oxygen inhalation unit starts a timer when the oxygen outlet is opened. The timer records the time value that increases from zero.

Based on the real-time working status parameters, the shared oxygen inhalation cabinet unit confirms that the oxygen outlet is in the closed state and generates a closed state confirmation signal.

[0076] Furthermore, after the query interface of the shared oxygen inhalation area machine receives the status query request data packet, it triggers the sensor acquisition program to start the built-in sensor to detect the oxygen outlet in real time. The pressure sensor measures the outlet pressure value, and the flow sensor detects the airflow rate. The real-time working status parameters are compared with the preset shutdown status threshold. When both the pressure value and the flow rate value are lower than the threshold, a shutdown status confirmation signal containing a confirmation identifier is generated.

[0077] S6.3 The shared oxygen therapy machine will send a shutdown status confirmation signal to the confirmation receiving port of the business server via the wireless network. After receiving the shutdown status confirmation signal, the business server will generate a final order by combining the time data in the stop signal.

[0078] Furthermore, the communication unit of the shared oxygen therapy machine encapsulates the off status confirmation signal into a response data packet and transmits it to the confirmation receiving port of the business server via a wireless network.

The cabinet-side decryption module receives encrypted data packets from the shared oxygen inhalation area machine, decrypts them, extracts the dynamic token and device identifier, forwards them to the authentication server for verification, and sends an authorization command to the cabinet after successful verification. In the service execution module, after receiving the authorization instruction, the cabinet unit drives the solenoid valve to open the corresponding oxygen outlet, starts the timer to start timing, monitors the working status of the oxygen outlet in real time through the built-in sensor, controls the solenoid valve to close the oxygen outlet, generates a stop signal with time data, and sends the stop signal to the business server in the cloud server.
