Distributed intelligent tunnel lighting system

Abstract

The invention provides a distributed intelligent tunnel lighting system which comprises a lighting centralized control device, lighting terminal dimming control devices, an outer-tunnel light intensity detection device, an in-tunnel lighting quality monitoring device, a traffic flow detection device, a lighting device, a communication device and a control platform. The lighting centralized control device is used for carrying out data acquisition on the lighting terminal dimming control devices distributed in the tunnel and issuing a control command, wherein the control command is obtained by comparing data acquired by the outer-tunnel light intensity detection device, thein-tunnel lighting quality monitoring device and the traffic flow detection device with an illumination dimming strategy set in the lighting centralized control device, so that the on or off of the lighting device in the tunnel and the lighting brightness are controlled. The system has the advantages of being high in controllability, not high in construction environment requirement and basically not limited by construction conditions.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a distributed intelligent tunnel lighting system. Background technique [0002] The prior art tunnel lighting dimming system consists of a main server computer, a monitoring center, a centralized controller (installed in a dimming control cabinet), a brightness meter, a communication and driving power supply, and dimmable lamps, etc. to form a dimmable control system. Each tunnel is an independent system that is not affected by the external network and can operate independently. To ensure that the failure of a single tunnel will not affect the normal work of other tunnels. The system uses a group of brightness data collectors outside the cave to input the collected data to the centralized controller. After the centralized controller processes the data, it controls the dimmable lamps for brightness adjustment through its own independent downstream communication syste...

AI Technical Summary

Problems solved by technology

[0004] (1) At present, tunnel lighting mostly adopts 0-5V dimming mode, and the length of the control loop should be set within 500 meters. Light control accuracy is not high, reliability is not high;

[0005] (2) For the lighting control system using single-lamp control equipment, the centralized control method is adopted, and the time for collecting data such as the real-time status and parameters of the single lamp is too long. The existing technology takes more than 15 minutes to complete a single-lamp inspection, which cannot meet the real-time requirements. monitoring needs
