Embodiment 2
The present embodiment discloses a kind of dispatching method that video monitoring equipment cluster cooperates, and guarantees video monitoring equipment at nobodyReliably working in situation on duty guarantees the reliability of system operation and the accuracy of tracking, specifically includes the following steps:
S01), original monitoring information acquisition component sends original monitoring information to early warning target analysis identification component in real time；
S02), early warning target analysis identification component analyzes received original monitoring information, identifies pre-warning signal type, soLinkage instruction is sent to multiple signals Transmit-Receive Unit afterwards, linkage instruction includes interlocking equipment ID, early warning target type, early warning targetPosition, early warning target sizes；
S03), other monitoring devices send each road signal instruction to multiple signals receiving unit, and signal instruction includes issuing equipmentID, instruction interface, director data；
S04), the instruction of multiple signals receiving unit real-time reception multiple signals and record buffer memory queue, to be arranged per signal all the wayProprietary buffer queue guarantees letter using instruction eliminative mechanism, instruction integrality judgment rule, instruction group integrality judgment ruleNumber instruction buffer be normally carried out and integrality；
There are overflow exceptions when multiple signals receiving unit receives instruction record buffer memory is washed in a pan in order to avoid the exception using instructionEliminate mechanism.Specifically, using oldest instruction eliminative mechanism in the present embodiment, i.e., an oldest order is abandoned when caching will be fullOr Management Information Base data, guarantee the normal cache of instruction.As the substitution of oldest instruction eliminative mechanism, can also use newestEliminative mechanism is instructed, i.e., abandons a newest order or Management Information Base data when caching will be full, guarantees the normal slow of instructionIt deposits.
In the presence of because being instructed caused by communication abnormality and instruction group when multiple signals receiving unit receives instruction record buffer memoryIntegrality lacks problem, and in order to avoid the problem, this method proposes checking command integrality decision rule and instruction group integralityDecision rule.Specifically, instruction integrality decision rule includes command length verification, the verification of instruction systematicness, instruction check codeVerification guarantees instruction integrality.Instruction group integrality decision rule is verified including instruction specific bit value, instruction group rule verifies,Instruction group verifies code check, guarantees the integrality of instruction group instruction.
S05), comprehensive cooperative scheduling unit reads from multiple signals receiving unit, dispatches each road signal quality information, and withState group logic unit carries out two-way communication, the constraint instructions of reception state group logic unit feedback, setting instruction classification, instructionPriority setting, instruction closed loop mechanism guarantee that device action is normal；
