Ultrahigh concurrent image data writing method and device and readable storage medium

Abstract

The invention discloses an ultrahigh concurrent image data writing method and device and a readable storage medium. The method comprises the following steps: establishing a hard disk drive processing thread for each mechanical hard disk accessed to a hard disk video recorder; receiving an image data writing request of an input source thread by using a thread scheduler, and determining a target processing thread for receiving image data requested to be written according to the real-time state of each processing thread; storing the image data in a cache queue of the target processing thread; and when a preset writing condition is met, writing the image data in the cache queue into a target mechanical hard disk. Obviously, the target hard disk drive processing thread for receiving the image data is determined according to the real-time state of each hard disk drive processing thread, and then the image data of the cache queue can be written into the target mechanical hard disk when the preset write-in condition is met, so that the write-in strategy of the image data is optimized, the write-in performance of the mechanical hard disk can be improved, and the user experience is improved. And the concurrent video recording efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and more specifically, to a method, device, and readable storage medium for writing ultra-high concurrent image data. Background technique [0002] In scenarios such as monitoring, conferences, Internet live broadcasting, and Internet of Things applications, multi-channel concurrent recording of audio and video content is required. Due to the limitations of traditional recording methods and the technical structure of mechanical hard disks, it has been unable to meet the growing demand for high concurrent recording scenarios. . [0003] The root cause is that the technical design of large-capacity mechanical hard disks is not suitable for concurrent software writing scenarios, especially in high-concurrency scenarios, the performance of mechanical hard disks will be severely degraded. Aiming at the insufficient performance of mechanical hard disks in high-concurrency recording s...

AI Technical Summary

Problems solved by technology

Aiming at the insufficient performance of mechanical hard disks in high-concurrency recording scenarios, the solutions and existing problems in the prior art are as follows: First, use high-concurrency solid-state hard disks instead of mechanical hard disks as video hard disks, but solid-state hard disks are expensive and do not have Universality; Second, increase the number of hard disk video recorders to improve recording efficiency. This method requires multiple hard disk video recorders, which will cause waste of hardware resources and cannot effectively utilize limited hardware resources
