Through the dual action of airflow and mechanical vibration, the screen clogging removal rate is effectively improved without manual intervention.

This invention discloses a screen preview management and delayed printing terminal system and method for food delivery orders. After receiving food delivery order data from at least one order source, the terminal first caches the order data as a food delivery order task that can be displayed, searched, sorted, and manipulated on the screen in a task view or receipt preview view. Then, printing is triggered based on user operation, task status changes, task sorting results, packaging or labeling needs, reprinting needs, or preset conditions, rather than using the order receipt time as the sole trigger point for printing the paper receipt. The terminal can be a standalone screen device, a software application running on a mobile phone, tablet, or general-purpose computing device, or an integrated food delivery receipt printing device integrating a display screen and a printing module. The printing function can be implemented through an integrated printing module or by forwarding data to an external printer via Bluetooth, network, USB, serial port, or a printing port proxy. The terminal can also report the merchant's food preparation status to the order source using an order identifier or platform identifier when the food delivery order task is marked as packaged complete. The above solution changes the traditional "print as soon as an order arrives" method of online food delivery receipt printers to "screen preview management first, then print on demand", solving the problems of receipt accumulation, lost receipts, difficulty in finding receipts, messy packaging, and duplicate reprints during peak periods.

This specification discloses a distributed screen inspection and repair control method, system, device, and medium. The method uses a monitoring module deployed on the screen terminal to collect real-time operating parameters and playback status logs of the screen device. The collected data is processed to extract key health data and generate a terminal status vector. This terminal status vector is then input into a pre-trained diagnostic model. Rule matching and anomaly detection algorithms are used to evaluate and calculate the terminal's health status. Based on the real-time health score of the terminal calculated by the diagnostic model, fault types are identified and fault levels are determined. Corresponding remote repair strategies are executed, and post-repair status data is collected to verify the repair effect and update the terminal's health status. This method effectively solves the problems of poor real-time performance, high labor costs, and slow fault recovery in existing screen maintenance, demonstrating significant technological advancement and broad engineering application value.
