Scheduling device and method for cooperative operation of video monitor equipment cluster

Abstract

The invention discloses a device and method for cooperative operation of a video monitor equipment cluster. The method raises an instruction elimination mechanism, and an instruction queue state is monitored in real time, so that instruction cache overflow is prevented; the method raises a determining rule for instruction integrity and instruction group integrity, solving a problem of lack of integrity of the instruction and instruction group due to communication abnormality, guaranteeing instruction legal and correct, and making the system more stable and reliable; the method raises instruction classification and instruction prioritizing manner, solving a conflict problem of executing of multiple problems, ensuring that the instruction is executed correctly, and preventing abnormal equipment actions; the method adopts a Petri network, limited state machine and other technological models, so as to constrain and guide coordinate scheduling of multiple signal instructions; and the methodraises an instruction closed loop mechanism, schedules the monitor equipment accurately, further, reduces abnormal jitter amid frequency instructions, and prolongs service life of equipment effectively.

Description

technical field [0001] The invention relates to a dispatching device and method for cooperative work of video surveillance equipment clusters, belonging to the field of intelligent video surveillance. Background technique [0002] Video surveillance is the physical basis for real-time monitoring of key departments or important places in various industries. Management departments can obtain effective data, images or sound information through it, and monitor and remember the process of sudden abnormal events in time to provide efficient , Timely command and altitude, deployment of police forces, handling cases, etc. With the rapid development and promotion of current computer applications, a powerful wave of digitization has set off all over the world, and the digitization of various devices has become the primary goal of security protection. [0003] With the development of science and technology and the improvement of application requirements, multi-functional and multi-fun...

AI Technical Summary

Problems solved by technology

[0006] When the existing multi-device cluster coordinates work, there are the following problems: when receiving multi-channel command signals of the device cluster in real time, there will be an exception of buffer queue overflow; the abnormality of reading the command signal, the illegal content of the command due to the abnormal communication, resulting in the loss of command integrity and The integrity of the command group is missing; the command conflict problem, multiple command sources call the same device at the same time, resulting in abnormal device action

These problems cause the system to fail to work reliably in unattended conditions in practical applications, and cannot achieve the required accuracy and reliability.
