For this situation, this paper uses the Siemens S7-200 and designs the system to control the campus lighting system instead of traditional artificial control，Programmable Logical Controller intelligent control system was adopted on the new campus, the control system is reliable enough to meet the requirement of campus lighting, The system mainly includes incident the output signal of the road、the decorative lights and the green fields. Which composes the I/0 allocation tables and flowing diagram and the ladder diagram control programs of the illumination system of the campus. Through the simulation, it is able to turn to manual control from the automatic system when the facilities generate the phenomenon of the malfunction and abnormal,the automatic system turn on after people to find and orderly deal with the malfunction ,and fulfills the requirements of the system of the intelligent control.
