AI Technical Summary
Technical Problem
[0002]现有船用动力验证平台在建设中普遍采用以下技术方案：在接入层与应用层部署Nginx主从配置与双机负载均衡，以Keepalived协议实现虚拟IP漂移和故障切换，路由权重为人工静态配置，切换触发完全依赖心跳检测轮询，导致在应用服务器资源耗尽趋向崩溃的过程中系统无法感知健康趋势、无法预防性迁移流量，只能等待故障发生后被动切换，切换期间试验任务指令通道中断；在存储层对全部数据对象统一采用固定三副本或固定参数纠删码方案，不区分试验实时采样数据与系统日志的重要性差异，导致低价值数据占用与高价值数据相同的冗余资源，存储利用率低；在协议转换层仅执行字节级格式映射，不验证物理量语义，导致台架上位机因固件升级改变单位后，转速数据以rad/s格式上报但平台仍按r/min解析，引发仿真模型输入端产生约60倍量级的误差；在时序数据存储层对全部采样序列统一应用固定的Delta-Delta差分编码，未考虑试验工况突变场景下相邻采样点差异剧烈的特点，导致二阶差分幅度急增时VarInt编码长度膨胀、压缩率退化；
Benefits of technology
本发明能够识别IP地址合法但行为异常的接入请求，将动态IP台架的误拒率降低至接近零的同时保留对异常行为的感知能力；以故障历史驱动的梯度下降权重更新机制，使路由层在应用服务器资源耗尽前完成预防性流量迁移，将应用层故障切换延迟从依赖心跳轮询的秒级降低至毫秒级；以数据关键度指数通过sigmoid函数动态映射校验分片数的纠删码机制，使存储冗余度与数据重要性匹配；以二阶差分幅度驱动编码模式动态切换的时序压缩机制，在试验工况突变期间维持30%至40%的压缩率，避免了固定Delta-Delta编码在突变段压缩效率退化至接近零的问题。

Abstract
The application discloses a kind of full-link high-availability operation method and system for marine power verification, the method includes: the integrated trust score is calculated to connection request and access decision is executed;Release request is generated data stream by message analysis and standardization.The response delay, resource occupancy and error rate of each application server are collected, the health score is calculated and normalized as routing weight, and the data stream is distributed to the server with the highest weight.After application server processing, the management class data and simulation model file are mapped to the number of check shards with the key degree index using the sigmoid function, and are written into the object storage in a dispersed manner.Management class data is written into a relational database.Physical sampling data is written into a time series database after adaptive time series compression.Interface clients prefetch simulation model files from the object storage to the simulation server, providing simulation access for multiple users.
