摘要
针对沈白高铁信号施工中系统接口兼容性高、天窗作业时效短、高寒环境可靠性低及多专业协调难四大核心问题,构建了融合信号架构解析、建筑信息模型(building information modeling,BIM)协同建模与自动化工艺的技术体系。结果表明,BIM模块化装配技术的应用有效提高了30%的安装效率,设备定位误差≤0.5 mm;智能调试平台实现了2000余接口点毫秒级验证,联调周期缩短了35%,-15℃工况参数漂移率降至0.3%;全时域监测系统通过500处传感器网络预警地质风险,使延误率降低,电缆故障率降至了0.15×10^(-3)次/h。该体系为复杂环境铁路信号施工提供了可参考的经验。
Based on four core problems of high system interface compatibility,short skylight operation time,low reliability in alpine environment and difficult multidisciplinary coordination in the signal construction for Shenyang-Baihe High-speed Railway,a technical system integrating signal architecture analysis,Building Information Modeling(BIM)collaborative modeling and automation process is established.The results show that the application of BIM modular assembly technology effectively improves the installation efficiency by 30%,and the equipment positioning error is not more than 0.5 mm;the intelligent debugging platform realizes the verification of more than 2000 interface points in millisecond-level,shortens the joint debugging period by 35%,and reduces the parameter drift rate under-15℃working condition to 0.3%;the full time domain monitoring system provides early warnings for geological risks through 500-sensor networks,reducing the delay rate and lowering the cable failure rate to 0.15×10^(-3) times/h.This system provides reference experience for railway signal construction in complex environments.
