Intelligent sensing control system for tunnel lighting lamps and signal lamps

Abstract

An intelligent sensing control system for tunnel lighting lamps and signal lamps comprises sensing terminals, a communication gateway, a signal lamp module and a management control unit. The sensing terminals comprise a group of sensing terminals arranged at a tunnel portal and N groups of sensing terminals arranged in a tunnel, and each sensing terminal comprises an integrated module integrating an illuminance sensing probe, a millimeter wave radar, a single-lamp intelligent sensing controller and a Bluetooth MESH; the communication gateway comprises a 4G / 5G communication chip and a Bluetooth chip; and the management control unit comprises a CPU master controller and a data communication unit, and is used for realizing management and parameter function setting of terminal perception, a communication gateway and lighting equipment of the tunnel. Real-time control of on / off and brightness of tunnel lamps is achieved, and the intelligent lighting effect that the lamp is on when a vehicle comes, the lamp is dark when the vehicle goes and the lamp goes along with the vehicle is achieved; and the intelligent sensing control system is effectively prevented from being in a lighting state in a large area for a long time, the energy saving problem when no vehicle passes in the tunnel is solved, and the safety problem when the vehicle passes in the tunnel is also ensured.

Description

technical field [0001] The invention relates to the field of tunnel lighting equipment, and mainly solves the problem of intelligent sensory control of tunnel lighting and signal systems, specifically an intelligent sensory control system for tunnel lighting and signal lights. Background technique [0002] At present, my country's expressways continue to extend to ethnic minority areas and remote areas. The bridge-to-tunnel ratio of expressways in these areas exceeds 70%, and tunnels account for more than 70% of the bridge-to-tunnel ratio, and some are even higher. After this type of tunnel is opened to traffic, the traffic flow at the beginning of the period is actually not large, and the distribution of passing time is uneven, which has become a prominent feature of this type of expressway tunnel. For the management of the lighting and signal system of this kind of expressway tunnel, if the light is dimmed according to the circuit and time sequence, it will cause a huge wa...

AI Technical Summary

Problems solved by technology

For the management of the lighting and signal system of this kind of expressway tunnel, if the light is dimmed according to the circuit and time sequence, it will cause a huge waste of lighting electricity when the traffic flow is small; if the overall lighting brightness is reduced, it may bring Tunnel traffic safety risk; the management of tunnel lighting and signal systems, whether to focus on saving or safety, has become a dilemma for the management department

[0003] An energy-saving lighting system for tunnels disclosed in document CN206658323U cannot perform single-lamp control, cannot finely adjust the brightness in the tunnel, and has poor energy-saving effects

An energy-saving sensing control system for tunnel lighting disclosed in the comparative document CN112040620A can finely adjust the brightness of the lighting lamps in the tunnel to achieve more precise power saving, but lacks precise control of the signal lights in the tunnel and is not effective for the signal indication of passing vehicles. It is clear that there is no signal prompt for safe driving for the "white hole" and "black hole" visual status of the vehicle exiting and entering the hole
