Description

Technical Field

[0001] The utility model relates to the technical field of library location information display terminals, in particular to a navigation query service terminal. Background Art

[0002] The library indoor navigation and inquiry service terminal is a device that provides convenient and efficient navigation and inquiry services for library users. That is, the navigation and inquiry service terminal can help people who come to the library for the first time or have never used the library service to answer what services the library can provide, what the specific process is, the functional division introduction, etc., and where there are branches; so as to quickly understand the library service population, coverage, facilities, library style, digital resources, etc. Its main functions include navigation services, which help users quickly find the required books and library facilities through built-in maps and positioning technology; inquiry services, which provide real-time library collection query functions, and users can obtain detailed information about books by entering keywords; publishing event and activity information, so that users can understand the latest library activity notifications; and self-service functions, such as self-service book borrowing and returning, seat reservation, etc., which facilitate users to manage library accounts. In terms of structure, the library indoor navigation and inquiry service terminal usually includes a display screen, input device, positioning technology, database and communication module. The display screen is used to display maps, query results and event information, and usually uses touch screen technology to provide a user-friendly operation interface. The input device is mainly a touch screen, which is used for users to enter query keywords and perform other operations. In order to provide accurate navigation services, terminal devices need to integrate positioning technologies, such as Wi-Fi positioning, Bluetooth positioning or other indoor positioning systems. The database stores library collection information, map data and other related information to support users' query and navigation needs. The communication module is used to communicate with the library system in real time, obtain the latest library information and keep the terminal device synchronized and updated, and its file self-cleaning function is an important feature of the terminal, including regular cleaning of cache, history, expired information, system logs and junk files to keep the system efficient and stable. At present, the library indoor navigation query service terminal still mainly interacts with users through touch screens. However, the touch screen is in a constant horizontal or vertical state after installation. When switching between the library information display interface and the map information interface, the map detailed interface is difficult to fully display the terrain information, that is, the display space of the map interface is limited, and it is difficult for users to fully see the terrain details, especially when more detailed map information is needed during the guided tour, which causes inconvenience for users to browse the guided information.
