AI Technical Summary

Technical Problem

In existing technologies, the data synchronization method of seat information displays is time-consuming and labor-intensive, which cannot meet the needs of rapid operation and maintenance of EMU or high-speed rail, and the equipment matching and upgrading is cumbersome.

Method used

The maintenance tool establishes near-field communication with the seat information display. Communication is triggered by magnetic induction intensity detection. The maintenance tool generates a magnetic field exceeding the preset value and matches the display to connect and perform near-field communication to achieve equipment upgrades and data synchronization.

Benefits of technology

Equipment upgrades or maintenance can be completed in a short time without disassembling the equipment, improving the operation and maintenance efficiency of EMUs or high-speed trains, simplifying the operation process, and enhancing the accuracy and security of communication and interaction.

Abstract

This application relates to the field of rail transit, specifically a seat information operation and maintenance system and method. The system includes a seat information display and an operation and maintenance tool. The seat information display is configured to detect the magnetic induction intensity of the magnetic field at its location. When the magnetic field intensity exceeds a preset value, the seat information display initiates near-field communication. The operation and maintenance tool is configured to generate a magnetic field with an induction intensity exceeding the preset value. After the seat information display initiates near-field communication, the tool matches and connects with the display to perform near-field communication. This application uses strong magnetic induction as a condition for activating near-field communication of the seat information display. Once activated, the operation and maintenance tool matches and communicates with the display, improving the communication accuracy, communication efficiency, and operation and maintenance efficiency of the seat information display. This solves the problem of the cumbersome process of matching and upgrading seat information displays during operation and maintenance.
