The invention discloses a dynamic control method for a rail transit environmental control system, which comprises the following steps of: judging whether sensor data in a sensor is in an effective range or not, and if so, predicting a thermal load trend according to the sensor data; if not, marking the fault sensor, reporting the state of the abnormal sensor, correcting data in the abnormal sensor, and predicting the thermal load trend; output control parameters of the water chilling unit are obtained according to the control parameter optimization result in combination with the thermal load change trend; optimizing the output control parameter through a control algorithm to obtain an initial output control parameter; and acquiring sensor data in the sensor again, and repeating the steps to obtain the target output control parameters. Operation efficiency of an environmental control system can be effectively improved and system energy consumption is reduced.

    本发明公开了一种轨道交通环控系统动态控制方法,通过通过判断传感器中的传感器数据是否在有效范围内,若是,则根据传感器数据预测热负荷趋势;若否,则对故障传感器进行标记后上报所述异常传感器的状态,并对异常传感器中的数据进行修正后预测热负荷趋势;根据控制参数优化结果,结合热负荷变化趋势,得到冷水机组的输出控制参数;通过控制算法对所述输出控制参数进行优化,得到初始输出控制参数;再次获取传感器中的传感器数据,并重复进行上述步骤,得到目标输出控制参数。能够有效提升环控系统运行效率降低系统能耗。
