Nowadays, with the rapid development of science and technology, great changes have taken place in the lighting field. It is necessary to study the urban intelligent energy-saving street lamp control system, which can save energy and reduce the consumption of manpower and material resources. This paper designs and builds an energy‐saving street lamp control system through single chip computer and related hardware facilities. The energy‐saving street lamp closes during the day, and some people or vehicles come at night, and the street lamp automatically lights up. When vehicles or pedestrians pass by, the street lights are automatically turned off for one minute. Even if pedestrians pass by during the day, the system will not be bright, this can save lots of energy. This set of intelligent energy street lamp control system is simple and practical in design, and has a high cost‐effective ratio. It is very suitable for road construction in major cities.
