Abstract

The invention relates to a highway tunnel energy-saving ventilation control method based on the wind speed. Multiple sets of jet fans and wind speed and wind direction detectors are arranged in a tunnel in sequence from front to back in a distributed mode; the wind speed is detected through the wind speed and wind direction detectors; and the start-stop states of the jet fans in the tunnel are controlled through a data processing and control system according to the detecting result. A control method of the jet fans comprises the steps that a wind speed detecting value, detected by the corresponding wind speed and wind direction detector, of a certain point in the tunnel is collected, and start and stop of the corresponding jet fans are controlled by a controller according to the wind speed detecting value and the change rate calculated by the historical data. The starting number of the jet fans is controlled according to the detected wind speed historical data and the change trend of the speed historical data, the ventilation effect is achieved, meanwhile, the service life of the fans can be prolonged, and energy consumption is reduced.

Description

technical field

[0001] The invention relates to the field of road tunnel ventilation, in particular to a wind speed-based energy-saving ventilation control method for road tunnels. Background technique

[0002] There are many types of tunnel ventilation methods, which can be roughly divided into natural ventilation and mechanical ventilation according to the air flow in the lane space. Mechanical ventilation is divided into four types: longitudinal ventilation, semi-horizontal ventilation, full-horizontal ventilation and combined ventilation. The longitudinal ventilation is divided into jet ventilation, centralized feeding ventilation, and vertical (inclined) well ventilation. Ventilation methods, vertical (inclined) well exhaust ventilation, electrostatic dust suction ventilation, etc.; semi-horizontal ventilation is divided into air supply semi-horizontal and exhaust semi-horizontal ventilation.

[0003] Effective ventilation control is an important measure to realize the...
