AI Technical Summary

Technical Problem

The difficulties in integrating multi-source heterogeneous data in public security technical defense systems, the lack of effective caching and synchronization mechanisms for asynchronous spatiotemporal data, and the low efficiency of device ID conflict detection lead to inconsistent data quality and system misjudgments.

Method used

Programmable logic chips and asynchronous cache units are used to cache spatiotemporal asynchronous data. Heterogeneous data is converted into a standard format through multiple types of physical interfaces and protocol conversion units. A data arbitration module is used to detect device ID conflicts and unify timing, thereby achieving efficient data verification.

Benefits of technology

It achieves standardized processing of heterogeneous data, ensures a unified time base, improves the efficiency of device ID conflict detection, reduces system misjudgments, and enhances the efficiency and accuracy of data quality governance.

Abstract

This utility model relates to the field of public security technical prevention data governance, and in particular to an intelligent verification device for public security technical prevention data quality governance. The device includes: a core processing module, including a programmable logic chip and an asynchronous cache unit; a multi-source input module, including multiple types of physical interfaces and a protocol conversion unit, wherein the multiple types of physical interfaces include at least one network interface and one serial interface, and the protocol conversion unit is used to convert heterogeneous data into a standard format; a data arbitration module, including a data selection unit, a conflict detection unit, and a time synchronization module. By setting up the multi-source input module, various technical prevention devices can be connected to achieve standardized processing of heterogeneous data and adapt to complex security scenarios; by setting up the asynchronous cache unit, inconsistent time data is efficiently cached, and in conjunction with the time synchronization module, the time base is ensured to be unified; by setting up the conflict detection unit, real-time detection and response to device ID conflicts can be achieved.
