Ventilation and lighting control system and method in tunnel

Abstract

The invention discloses a tunnel ventilation and illumination control system and method. The system comprises a pavement and a tunnel, wherein the pavement penetrates through the bottom of the tunnel, a highway pavement structure is arranged on the pavement, and the tunnel is provided with an entrance and an exit. The system further comprises a signal demodulator A, a device controller A, an electronic deceleration warning sign, a time difference demodulator, a signal demodulator B and a device controller B. A plurality of fans and a plurality of illuminating lamps are arranged on the wall of the arch apex of the tunnel, and a piezoelectric element set A, a piezoelectric element set B and a piezoelectric element set C are arranged outside the tunnel and located on the portion, near the entrance of the tunnel, of the pavement. The device controller A and the device controller B are electrically connected with an external power source through wires respectively. By embedding the piezoelectric element sets in the portion, near the entrance of the tunnel, of the pavement to detect the position and operating speed of a motor vehicle and calculate the time for the motor vehicle to pass through the tunnel, precise control over tunnel ventilation and illumination is achieved, and the purposes of saving energy and protecting the environment are realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection tunnel engineering, in particular to a ventilation and lighting control system and method in a tunnel. Background technique [0002] With the rapid development of the national economy, my country's infrastructure construction has gradually improved, and road construction has also increasingly increased high-tech components. In order to choose a better line shape and improve driving quality, road crossing mountains and ridges has become a common technology in road construction, and the proportion of tunnels in road engineering is gradually increasing. Compared with ordinary pavement, the tunnel pavement project has the characteristics of less influence of environmental factors and lower driving speed. During operation, the tunnel needs enough fresh air to meet the power demands of motor vehicles, and provide sufficient lighting to ensure clear vision of motor vehicles in the tunne...

Problems solved by technology

The above-mentioned management scheme is likely to cause the fan and lighting equipment to work as usual when there is no vehicle, which causes a waste of energy in tunnel operation and management
