A playground system based on USN for managing the amount of reduction of CO2 on a real time base is provided to supply independent electric power generated by environment friendly rides to various facilities in the playground. One or more environment-friendly ride(100) includes power generator(110). A central condenser(200) stores the independent power amount generated in the power generator. A server system(300) obtains the history information including the independent power generation amount information of the user through the wire/wireless network(14). The power display(120) indicates the carbon dioxide reduction amount corresponding to the generated independent power generation amount as described above. USN sensor node(130) stores tool identification ID, user identification ID, and independent power generation amount information. |
