Method and system for improving automatic recognition rate of electronic license plate rower middleware system

Abstract

The invention provides an electronic license plate rower middleware accumulation subsystem, which comprises a first-level cache, a result cache, a matching engine and a reporting engine, wherein the first-level cache is used for caching electronic license plate information which is recently read by a reader by using a rower protocol by middleware; the result cache is used for caching combined electronic license plate tag information; the matching engine is used for comparing data in the first-level cache with the data in the result cache, combining the data in the first-level cache and the data in the result cache and replacing the data in the result cache with the combined data if the data are matched, and directly moving the data in the first-level cache into the result cache if the data are not matched; and the reporting engine is used for periodically extracting the electronic license plate information in the result cache, reporting the electronic license plate information to the middleware and clearing the result cache. The accumulation subsystem is introduced into an electronic license plate rower middleware system and a combining mechanism is added, so that the business processing accuracy is improved under the condition of not affecting an original processing flow.

Description

technical field [0001] The invention belongs to the technical field of electronic license plates, in particular to an auxiliary system used in the middleware of electronic license plates. Background technique [0002] When the vehicle passes through the radiation range of the reader, the reader will read the vehicle's electronic license plate information. How the server reader reads the electronic license plate is determined by the line marking protocol, such as figure 1 . [0003] Usually, the middleware uses the line marking protocol to make the reader work periodically to read the information of multiple positions in the electronic license plate. The reader reports the read results to the middleware, and the middleware performs filtering and grouping. [0004] However, due to the vehicle speed, angle and other reasons, the success rate of the reader to operate the tag is not satisfactory. Suppose the middleware makes the reader read the data of M areas. When the effec...
