Method and device for querying checkpoint

Abstract

The invention provides a method for querying a checkpoint. The method for querying the checkpoint comprises the following steps that A, information, input by a user, of the checkpoint to be queried is received, and the organization tree code corresponding to the checkpoint information is queried; B, according to the organization tree code, a database is searched for corresponding checkpoint data, wherein the database records the organization tree codes of checkpoints, an organization tree comprises a root node, leaf nodes and middle modes which are arranged between the root node and the leaf nodes, each node is provided with a symbol corresponding to the node, each leaf node represents one checkpoint, the root node and the middle nodes represent the organizations which the checkpoints belong to, an organization hierarchical relationship exists between the nodes on the paths from the root node to the leaf nodes, and the checkpoint organization tree code is a character string which is formed after the symbols of all the nodes on the path from the root node to the checkpoint are ranked in sequence. By the adoption of the method for querying the checkpoint, all the checkpoints under one organization can be queried, the limitation of the number of the checkpoints does not exist, massive checkpoints can be queried under a few of query conditions, mixed query of the checkpoint and the organization is flexible and convenient, and the usability is high.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a method and device for checking bayonets. Background technique [0002] In the urban road traffic checkpoint system, vehicle information management is one of the important functions. Its function is mainly to save various information (such as time, location, speed, vehicle type, pictures, alarm information, etc.) data. The speed and flexibility of the function of retrieving past vehicle information become the key factors to improve the user experience. When the retrieval speed of the database cannot meet the demand, a search engine is usually used to improve the flexibility and speed of the search, and realize various retrieval methods such as fuzzy retrieval, wildcard retrieval, and multi-condition retrieval. However, limited by the performance of search engines, the total number of search terms often has an upper limit. [0003] In the actual checkpoint sy...

Problems solved by technology

Sometimes, there is even a search requirement for multi-level bayonet selection, such as selecting the passing information of all bayonets in the xxx area for a certain period of time, and then selecting the passing information of all bayonets in the upper-level city of the xxx district for that period of time. For vehicle information, if a single bayonet is used as the selection condition for multi-condition query, when the number of bayonets is large, the retrieval speed cannot meet the requirements; or the search engine’s search criteria limit is reached, and the search requirements cannot be met.
