Embodiment

[0093] The tunnel is 2.5km long. There are two 300kw exhaust axial flow fans in the tunnel ventilation shaft, two 300kw air supply axial flow fans, and 4 sets of jet flow fans in the front and rear sections of the middle shaft. The distance between each set is 150m. Including 3 jet fans with a power of 30kw. Each axial flow fan for air supply and exhaust is installed with a general-purpose frequency converter, and the power of the general-purpose frequency converter should be greater than or equal to the axial power of the axial flow fan for air supply or exhaust; A programmable controller is installed, among which, a programmable controller of an axial flow fan or a jet fan is selected as the master station, and the rest of the programmable controllers are used as slave stations, and the master station and the slave stations are connected by communication lines.

[0094] The tunnel is equipped with vehicle detectors, CO detectors, VI detectors and wind speed and direction det...

Description

technical field [0001] The invention relates to the technical field of fan control and power saving, in particular to a system and method for optimally controlling the efficiency of fan groups in long highway tunnels. Background technique [0002] With the development of my country's road transport industry, the number and scale of long road tunnels are constantly increasing. However, during the operation of long highway tunnels, the power consumption of the ventilation system has always been a large expenditure. Pollutants in the air in highway tunnels mainly include particulate matter, carbon monoxide, hydrocarbons, and nitrogen oxides. Once the concentration of pollutants exceeds the standard, it will cause great harm to the human body. Therefore, the outside air must be continuously transported into the tunnel to ensure Normal breathing of personnel, driving safety, and air quality in the tunnel. [0003] The tunnel ventilation system and conventional design stipulated...
