Intelligent control system for tunnel lighting

Abstract

The invention discloses an intelligent control system for tunnel lighting. The system is used for controlling the brightness of stepless dimming lighting equipment in a tunnel. The system comprises adata acquisition system, a wireless communication system and a power line carrier system, the data acquisition system is in one-way communication connection with the wireless communication system, thewireless communication system is in one-way communication connection with the power line carrier system, and a decision signal is output; the data acquisition system comprises a Doppler moving objectdetection module, a TMR magnetic resistance detection module and an illumination intensity detection module, and is in communication connection with the wireless communication system through the controller; the wireless communication system is a Zigbee wireless communication system; and the power line carrier system uses a cluster tree network for communication, the power line carrier system controls a DAC pin to output corresponding analog voltage by analyzing the decision signal, the analog voltage is converted by an I / V conversion circuit, and then different control currents are output tocontrol the brightness of corresponding lighting equipment. The system is high in intelligent degree and good in control effect.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering supporting equipment manufacturing, in particular to an intelligent control system for tunnel lighting. Background technique [0002] In the construction of expressways, the safe and rational construction of tunnels occupies a large proportion. Due to the relatively closed environment and small space, there is a large gap between the light intensity values ​​inside and outside the tunnel, and tunnel lighting is the key to driving safety in highway tunnels. It plays an important role in the construction and monitoring system of highway tunnels. The tunnel lighting system is also a high energy consumption system in the road tunnel, which consumes a lot of electric energy, and the electricity cost occupies a large proportion of the operating cost of the road tunnel. Therefore, research on tunnel lighting energy-saving technology has very important practical significance and broad applicat...

Problems solved by technology

However, this control method in the prior art has a single perception method and a low fault tolerance rate. The tunnel lighting always maintains the uniform brightness of the LED lights, which greatly reduces the service life of the LED lights and is also a great waste of electric energy; intelligent The level is low, it is not easy to maintain, and at the same time, it cannot eliminate the glare phenomenon very well, and it cannot achieve a good energy-saving effect. For the long tunnel environment, the hidden safety hazards are gradually highlighted.
