Directory tree-based information acquisition method and device

Abstract

Embodiments of the invention provide a directory tree-based information acquisition method and device. The method comprises the steps of determining a root node of a directory tree according to a first dictionary; taking the root node as a current node of the directory tree, determining a child node corresponding to the current node according to the corresponding relationship between the keyword and the value in the first dictionary, and adding the child node to the directory tree; determining a leaf node corresponding to the branch node according to a corresponding relationship between each keyword and a value in a second dictionary, and adding the leaf node to the directory tree to obtain a target directory tree; and operating the target directory tree through a terminal to obtain directory information. According to the method, the branch nodes and the leaf nodes of the directory tree can be loaded into the memory at a time, the target directory tree is rapidly constructed, millisecond-level search is achieved, millisecond-level complete expansion is achieved, and a user can rapidly obtain monitoring information.

Description

Technical field [0001] The present invention relates to the technical field of video networking, in particular to a method and device for acquiring information based on a directory tree. Background technique [0002] Vision Network has installed a large number of monitoring equipment in organizations at different levels in various provinces and cities across the country. The monitoring equipment and its affiliated organization information exist in hundreds of thousands of network data packets through resource sharing. In order to grasp the specific information of these monitoring equipment, the monitoring equipment and the corresponding organization information can be parsed from the network data packet, and displayed to the user by constructing the monitoring organization directory tree, so as to facilitate the user to verify whether the monitoring equipment is correctly mounted on Under the corresponding organization, check whether the information of a certain monitoring device...

The above process requires the user to click all the nodes one by one to expand the entire directory tree, which requires a large amount of operation; moreover, since the program takes time to query the database, the query operation uses the SQL statement operation of the database to filter the data. This hierarchical loading method gives the user the impression that when a node is clicked, the program will wait for a while until the child nodes are fully expanded before proceeding to the next step, which is very time-consuming

[0004] As the data volume of monitoring information and organizational information of the Internet of Things expands to millions, the amount of user operations and time consumed by the above-mentioned directory tree construction method are very unacceptable, which makes it more difficult for front-end users to obtain monitoring information.
