By purchasing ingredients and installing them by our workmen, it could save about 10,000,000 dollars, and the economical benefits were about 300,000 kW/h. The management system of campus’ street light still cooperates with the company, it will plan to set up a smart-control system of street light, construction of soft/hardware system and surveillance computer, and elevate smart management of street and economical benefits.
