Aiming at deficiencies of current tunnel lighting control system on energy saving

safety and stability

a new tunnel lighting control system based on wireless sensor networks（ WSNs） is designed

and the whole architecture of the system is established. The system uses Zig Bee module CC2530 as core of WSNs

and information such as vehicle flow and lightness in tunnel collected by each node are processed

and transmitted to remote monitoring computer. Power supply circuit

debugger circuit

RS—232 interface circuit of the system are designed

corresponding software control system is completed. Software simulation and mathematical analysis shows that the system can effectively control continuity of light

and energy-saving effect is good.
