The invention discloses a tunnel lighting energy-saving control method, which belongs to the technical field of tunnel lighting, and is characterized by comprising the following steps of: a, installing a tunnel lighting energy-saving sensing
control system in a tunnel; b, powering on and starting a local controller; c, monitoring whether setting parameters are input into a
serial port screen or not; d, powering on and starting a single-lamp dimming controller; e, initializing starting working parameters of a
millimeter-
wave radar; f, sending
radar detection
waves; and g, dynamically adjustingthe illumination brightness of lamps in the tunnel through using a single-lamp dimming controller. By adopting the tunnel lighting energy-saving control method, single-lamp control can be carried outthrough using a distributed communication
algorithm in combination with brightness and
time information inside and outside the tunnel, brightness of all positions in the tunnel is finely adjusted,
electricity consumption of tunnel lighting can be effectively saved, operation cost is reduced,
driving safety can be improved by intelligently adjusting the lighting brightness of an entrance and an exit of the tunnel, the tunnel lighting effect is improved, and the energy saving effect and safety are guaranteed.
