Abstract

The invention relates to the technical field of road tunnel ventilation, in particular to an environment prediction-based tunnel ventilation control method and system. The tunnel ventilation control method comprises the steps of setting target values of indexes related to a tunnel environment; collecting detection values of the indexes at a current moment; according to the detection values of theindexes and a prediction model built through deep learning, predicting prediction values of the indexes at a next moment; and according to the detection values, the prediction values and the target values of the indexes, adjusting ventilation volume of a tunnel. The tunnel ventilation control system comprises a fan set, a detection apparatus and a control apparatus, wherein the fan set is arrangedin the tunnel; the detection apparatus is arranged corresponding to the fan set; and the control apparatus is connected with the fan set and the detection apparatus. According to the environment prediction-based tunnel ventilation control method and system, the hysteresis of air volume feedback control can be reduced and the ventilation volume control accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of highway tunnel ventilation, in particular to a tunnel ventilation control method and system based on environment prediction. Background technique [0002] With the continuous advancement of urbanization, the construction of road tunnels plays an important role in alleviating traffic congestion on main roads in central urban areas and reducing road surface environmental pollution. Since the tunnels are all semi-enclosed structures, a large amount of exhaust gas will be emitted when the vehicles running in the tunnel pass through the tunnel. Exhaust gas generally contains a large amount of harmful components such as carbon monoxide, nitrogen oxides, hydrocarbons and lead. If the tunnel is not ventilated, the exhaust gas emitted by the vehicles running in the tunnel will seriously pollute the air, which will seriously affect the drivers and passengers. and the health of the staff in the tunnel. [0003] In...
