Description

Fire-fighting operation analysis method for data center Technical Field The invention belongs to the technical field of fire-fighting operation simulation, and relates to a data center fire-fighting operation analysis method. Background With the rapid development of informatization construction, a data center is used as a key information infrastructure and bears massive service data and core application, and the safe and stable operation of the data center faces a plurality of challenges, wherein the fire disaster forms one of the most serious threats due to the characteristics of strong burst, rapid spread and great destructiveness. Traditional data center fire control simulation generally adopts a static design and isolation test method to carry out security verification, and the method has obvious limitations. The existing simulation method often simulates the physical response of facility equipment as a deterministic process, and takes key links such as signal verification, authorization decision and the like related to personnel operation as static preconditions or ignores the key links. The simulation evaluation cannot be reflected in actual fire conditions, and the reliability of a safety simulation conclusion is insufficient due to specific interference and delay caused by factors such as personnel judgment time, misoperation or communication delay to the issuing time of a key intervention instruction and a follow-up action sequence. In addition, because the existing methods generally treat fire-fighting response as static or simplified flow, traditional simulation methods have difficulty in coherently simulating higher authority or multiple information cross-verification and other upgrading steps in an emergency plan after flow interruption. These models cannot describe the specific execution of the upgrade process, cannot quantify the time required and the likelihood of re-failure, nor can they integrate such complex results into a unified evaluation framework, resulting in a blurred real performance boundary of the system in abnormal conditions. Finally, most of the existing evaluation conclusions are based on scoring or standard reaching judgment on the performances of each independent module, and it is difficult to automatically judge whether the root cause of the final treatment delay is an inherent defect of an initial information transmission link, a loophole of a medium-term decision logic or a configuration problem of later execution resources. This makes the development of improvement measures lacking clear, direct basis. Disclosure of Invention In view of this, in order to solve the problems set forth in the background art, a fire-fighting operation analysis method for a data center is proposed. The invention aims at realizing the technical scheme that the data center fire control operation analysis method comprises the following steps of constructing a digital twin model for mapping physical space, equipment and fire control facility layout and association relation of the data center. And taking the position of the fire source as a trigger condition, dynamically deducting the fire extinguishing process based on the digital twin model, and outputting a fire extinguishing time sequence chain comprising a time sequence and a coverage area. Alarm verification is executed based on a fire extinguishing timing sequence chain, alarm events are sequentially processed according to a receiving sequence, and double-ring-section verification of detection signal verification and manual confirmation verification is executed; if any link fails to verify, a degraded operation mode is entered and verification failure nodes in the digital twin model are recorded. And starting a double confirmation process comprising the identity of the operator and the video based on the verification failure node, and triggering a substitute confirmation signal if the process fails. The fire extinguishing timing sequence chain, the verification state of each link and the confirmation result are comprehensively analyzed to judge the overall safety state of the system, the safety is judged only when the fire extinguishing process is controlled, all alarm events pass through the double-link verification and no confirmation failure exists, and otherwise, the weak point is positioned and the marking signal to be reinforced is generated. Compared with the prior art, the invention has the beneficial effects that (1) the problem that human factors are ignored in the traditional static simulation is solved by constructing the digital twin model for mapping the physical space and the fire-fighting facilities and combining the dynamic deduction triggered by the fire source and the double-ring-section verification mechanism. The method can accurately quantify the influence of operation delay and signal verification time sequence on the whole response flow, so that the safety evaluation is closer to a real scene, the system weakness c
