摘要:
智慧空调技术作为城市轨道交通车辆智能化运营的重要技术手段，主要根据车辆运行环境数据来调整空调运行模式，进而改善车内舒适度，对空调机组运行状态进行实时监测及关键零部件故障预警，实现空调机组的智能化健康管理，提升空调运营维护效率。智慧空调系统由车辆空调、车载网络及PHM（故障预测与健康管理）地面支持系统结合搭建而成，通过传感器来监控车辆空调使用环境数据，并自适应性调节空调运行状态以改善车内空气质量。在故障预测及健康管理方面，智慧空调技术通过搭建诊断模型，采集并传输空调机组运行状态数据，实现对空调机组多发性故障的及时预警，对关键零部件使用寿命进行老化预测并采取相应的健康管理措施，进而保障空调机组的安全运行。在车辆的维修维护中，智慧空调技术结合不同的诊断及预警模型数据，合理制定空调机组修程，将空调机组故障修与定时修为主的传统维修模式发展为基于安全监控和健康管理的智能化“状态修”模式。
Abstracts:
As an important technical means of urban rail transit vehicle intelligent operation, smart HVAC (heating, ventilation and air-conditioning) technology mainly adjusts the AC (air-conditioner) operation mode according to the vehicle operating environment data to improve ride comfort, conducts real-time monitoring of AC units operation status and fault prediction and early-warning of key components, so as to realize intelligent health management and improve the operation-maintenance efficiency of AC units is improved. Smart HVAC system is established by combining vehicle AC, vehicle on-board network and PHM (prognostics health management) ground support system, setting sensors to monitor the environment data and adaptively adjust the AC operation status to improve the interior air quality. In terms of PHM (prognostics and health management), the safe operation of AC units is guaranteed by building a diagnostic model, collecting and transmitting AC unit operation data, timely warning frequent faults of AC units in time, predicting the service life of the aging key components and taking corresponding health management measures. For vehicle maintenance, with different diagnostic and prediction model data, the smart HVAC technology formulates reasonable maintenance process for AC units and develops the conventional maintenance mode, turning fault repair and timing repair into an intelligent ′state repair′ mode based on safety monitoring and health management.
