Embodiment Construction

[0035] When the driver enters the tunnel entrance, due to the large difference in brightness between the inside and outside of the tunnel, the driver's eyes need to go through a certain amount of adaptation time to see the situation inside the tunnel clearly. Similarly, it takes a while for the driver to adapt to the light and dark changes inside and outside the tunnel at the moment of driving out of the tunnel, which is the so-called "black hole" and "white hole" effect. If the speed of the vehicle is fast, the "black hole" and "white hole" effects can easily lead to the reduction of the driver's visual function and the lack of reaction time, thereby causing traffic accidents. Therefore, the light intensity of the lamps in the reinforced section of the tunnel entrance should be adjusted according to the light intensity outside the tunnel. In this way, the lighting system in the reinforced section of the tunnel entrance can reduce the difference in brightness between the inside...

Abstract

The invention relates to a solar power supply system and control method used for a tunnel entrance reinforcing section. The solar power supply system used for the tunnel entrance reinforcing section comprises a storage battery, a remote monitoring terminal, a plurality of solar panels and a plurality of power supply modules. Each power supply module comprises a controller, a relay, an inverter circuit and lamps. The solar panels are arranged outside a tunnel. The lamps are arranged at the position of the tunnel entrance reinforcing section. Power is supplied to the lamps at the tunnel entrance reinforcing section through solar energy, the power supply requirement of the lamps at the tunnel entrance reinforcing section is met, and the solar power supply system has the advantages that automatic control is achieved, energy sources are saved, and manual switching is not needed. Electric energy directly output by the solar panels can be supplied to power supply loops of the lamps, electric energy stored by the storage battery can be supplied to the power supply loops of the lamps, the lamps can be turned on in a grouped and batched mode according to the irradiation intensity, and illumination inside and outside the tunnel can be kept coincident.

Description

technical field [0001] The invention relates to the fields of environmental protection and solar energy reuse, in particular to a solar energy power supply system and a control method for a reinforced section of a tunnel entrance. Background technique [0002] Highway tunnels are an important part of mountainous highways. In order to ensure driving safety, it is usually required that a certain number of lighting fixtures must be installed in road tunnels with a certain length. In order to save the construction and operation costs of lighting fixtures, the lighting of the main tunnel with a length of more than 500m is respectively set according to the "Code for Lighting Design of Highway Tunnels" (draft for approval) "Entrance reinforcement section 1 lighting, entrance reinforcement section 2 lighting, transition section 1 lighting, Transition Section 2 Lighting, Intermediate Section Lighting, Exit Section 1 Lighting and Exit Section 2 Lighting", and the lighting of each road...
