Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] as attached figure 1 As shown, the advertising lighting adjustment system based on the piston wind in the railway tunnel includes a power supply module, a weak current control module, a strong current circuit module and a wind pressure sensor arranged in the tunnel, where the power supply module includes a wind power generation device connected in sequence, and an AC / DC conversion circuit and storage batteries, the wind power generation device is a vertical axis wind power generator, and the use of the vertical axis wind power generator can effectively reduce the space occupied inside the tunnel, and can effectively improve the utilization rate of wind energy.

[0029]Part of the piston wind generated by the train in the tunnel acts on the wind power generation device. The wind power generation device converts part of the wind energy...

Abstract

The invention relates to a system and method for regulating advertising lighting based on railway tunnel piston wind, the system comprises a power supply module, a weak current control module, a strong current circuit module and a wind pressure sensor, and the strong current circuit module comprises advertising lighting equipment; the power supply module comprises a wind power generation device, an AC-DC converting circuit and a storage battery, and the storage battery supplies power to the wind pressure sensor and the weak current control module; the wind pressure sensor is connected with the weak current control module so as to convert a wind pressure signal generated by the piston wind to an electrical signal and transmit to the weak current control module; the weak current control module is connected with the strong current circuit module, and the weak current control module controls on / off of the strong current circuit module according to the received electrical signal of the wind pressure sensor. According to the invention, ineffective power supply of the advertising lighting equipment can be greatly reduced through the piston wind generated in the tunnel, a practical test shows that about 90% power supply time of the advertising lighting equipment can be reduced, and the power supply can be greatly saved.

Description

technical field [0001] The invention belongs to the technical field of tunnel lighting, in particular to an advertising lighting adjustment system based on railway tunnel piston wind. Background technique [0002] With the rapid development of the current economy, the requirements for the transportation industry are getting higher and higher. Subway trains will become the main force of urban transportation due to their characteristics of large passenger capacity, high speed and punctuality, low energy consumption and low pollution. With the rapid development of the global economy, the transportation industry in China and the world is changing rapidly. According to statistics, the total mileage of China's rail transit will be nearly 2,700km by 2015; it is estimated that by 2020, 177 operational lines will be built in 28 cities in China, with a total mileage of about 6,100km; by 2050, 290 lines will be built in China Urban rail transit lines with a total mileage of about 11,...
