[Abstract]:Aiming at the problems existing in the traditional tunnel lighting system, such as poor environmental adaptability, large energy waste, high environmental pollution, low safety level and low intelligence level, this paper takes "on-demand lighting" as the concept in the field of highway tunnel lighting. Based on new LED lighting technology and energy saving and environmental protection, a new operation mode and control method of tunnel lighting energy saving system are established. Through linear interpolation, step linearization and logarithmic dimming to smooth the curve, the model of luminance change curve under the mode of energy saving operation is established, and the tunnel entrance section is dynamically adjusted, the three parameters of the vehicle flow speed are input into the model, and the linear interpolation method, step linearization and logarithmic dimming are used to smooth the curve. The length and brightness of each section of the transition section, middle section and outlet section make the tunnel lighting system safe, efficient, economical and energy-saving. Based on industrial Ethernet RS485 bus and ZigBee wireless technology, the communication network is constructed from top to bottom, with intelligent control as the main control, semi-automatic control and manual control as auxiliary design of tunnel lighting control mode, and DALI-M protocol as tunnel lighting control protocol. In order to ensure the reliability and veracity of the whole system, the lower computer system adopts hierarchical modularization design, which is divided into three modules: tunnel monitor main controller, Dali master controller and DALI slave controller. Among them, the CPU module, power module, power module, The key circuits such as LED constant current drive dimming module and so on are designed and realized in the data communication module. The upper computer system is based on the new operation mode and connects the lower computer system to receive and display the environmental parameters in real time. The luminance of tunnel LED lighting is dynamically adjusted, the tunnel lighting status is displayed in real-time on the graphical tunnel plan, the system abnormal alarm is displayed and alerted in real time, and the predefined control mode is automatically switched under the abnormal condition of the system. In order to improve the efficiency of tunnel managers and the level of system intelligence, an intelligent adaptive tunnel lighting control system is realized. Finally, the software and hardware of the system are debugged, and the feasibility of the system is demonstrated on the tunnel sand table model. The expected effect has been achieved.
