大数据中心技术的工程数智化指挥中心
作者：互联网
指挥中心分为项目空间设计、智能化硬件建设和软件系统建设三部分内容，打造了集声、光、空调、语音、屏幕、人脸识别等多种物联网技术以及APP，语音等多场景多方式的控制方式的智慧场景，采用全球先进的桌面交互系统，稳定且炫酷的OLED全透明操作屏，提供视觉呈现方案。同时也采用“云桌面方式”为指挥中心提供更为便捷轻量级的系统操控体验，以指挥操控技术和信息技术为主导，工程全过程经营管理数据为核心，将企业经营与项目紧密结合，实现工程现场数据全面汇聚、管控预警指标全面见识、管控运营数据全面钻取、公司数字孪生全面构建。既可为企事业单位打造智慧建筑场景应用，又能为项目业主，施工单位提供集预警、应急处理、视频、会议于一体的工程管理应用指挥产品。
工程数智化指挥中心被评选为新型智慧城市建设示范项目。
