Bottom Line: And the remote monitoring, wireless communication, and PWM dimming module of this system were designed emphatically.Intensity detector and vehicle flow detector can be configured in wireless intelligent control system, which gather the information to the master control unit, and then the information is sent to the monitoring center through the Ethernet.The control strategies are got by the monitoring center according to the calculated results, and the control unit wirelessly sends parameters to lamps, which adjust the luminance of each segment of the tunnel and realize the wireless intelligent control of combined illumination in road tunnel.

ABSTRACT
Because of the particularity of the environment in the tunnel, the rational tunnel illumination system should be developed, so as to optimize the tunnel environment. Considering the high cost of traditional tunnel illumination system with high-pressure sodium (HPS) lamps as well as the effect of a single light source on tunnel entrance, the energy-saving illumination system with HPS lamps and LEDs combined illumination in road tunnel, which could make full use of these two kinds of lamps, was proposed. The wireless intelligent control system based on HPS lamps and LEDs combined illumination and microcontrol unit (MCU) Si1000 wireless communication technology was designed. And the remote monitoring, wireless communication, and PWM dimming module of this system were designed emphatically. Intensity detector and vehicle flow detector can be configured in wireless intelligent control system, which gather the information to the master control unit, and then the information is sent to the monitoring center through the Ethernet. The control strategies are got by the monitoring center according to the calculated results, and the control unit wirelessly sends parameters to lamps, which adjust the luminance of each segment of the tunnel and realize the wireless intelligent control of combined illumination in road tunnel.

Mentions: Taking into account that the central controller fails, this will directly lead to all tunnel lamps being out of control. The modularized structure is used in the design of software system. KEIL C51 is developed through 51 series MCU produced by KEIL Software Company. The development schemes based on various functions and emulator-based debuggers are combined together by using KEIL C Uvision integrated developing environment, which provide a powerful integrated development debugging tool and abundant resources. The Uvision is a new powerful integrated developing environment (IDE) for Windows, which can finish the whole development process of editing, compiling, connecting, debugging, and simulation. Firstly, IDE itself or other editors are used to edit the C programming and compile the assembler. Then, the standard HEX files are generated, which can process the debugging of source codes. Finally, the debugged source codes are written in chip-FLASH through simulator. The main program flow is shown in Figure 7.
