As an important part of ensuring traffic safety of highway tunnel, highway tunnel lighting system has some problems such as high energy consumption and low degree of intelligence in its use. In this paper, a set of intelligent dimming system for highway tunnel lighting is designed, which takes the environmental variables such as luminance value and traffic flow information inside and outside the tunnel as input, establishes the intelligent dimming mathematical calculation model, adjusts the output power of the system in real time, and then adjusts the brightness of LED lamps. At the same time, the system connects with the remote management system through Ethernet remote communication technology, and can also realize the function of remote dimming. It improves the intelligent level of highway tunnel lighting and reduces the energy consumption of highway tunnel lighting system.
Aiming at the problems of cumbersome, time-consuming, inefficient and unable to create an accurate and controllable light environment for the input of the dimming system in the existing road tunnel lighting dimming quality inspection process, this paper designed a set of road tunnel lighting brightness intelligent detection system. The system fixes 5 illuminance sensors in a vehicle-mounted manner to achieve continuous measurement of longitudinal measurement points on the tunnel road surface and synchronous measurement of lateral measurement points; a programmable light source installed outside the tunnel provides a controllable brightness input for the dimming system, and uses the LoRa wireless technology completes the long-distance wireless communication with the inspection vehicle, which can realize the analysis and management of the measurement data. The whole system is convenient, efficient and intelligent, which can be applied to highway tunnel lighting quality monitoring and operation management.

Highway tunnel lighting equipment, as an important equipment to ensure traffic safety in highway tunnel, has some problems in its production, installation, commissioning and operation, such as low intelligence degree and weak man machine interaction operation. On the basis of studying the existing test methods of highway tunnel lighting equipment, this paper designs an improved test process and method of highway tunnel lighting equipment, builds a cloud management platform for test data, realizes the automatic test of highway tunnel lighting equipment by using remote client combined with Ethernet, realizes the intellectualization of test process and the standardization of test data. The database and background management software deployed on the remote server can realize the classified management of many kinds of test data. The system can improve the testing efficiency of lighting equipment for the highway tunnel lighting equipment production enterprises, and improve the management efficiency and quality for the highway tunnel lighting management department.
