The design of Energy-saving street light control system model
Abstract: To achieve energy saving, design a conceptual street automatic control system, car (people) to the lights, the car (people) through the lamp off function. The model using single-chip microcontrollers, reed beneath the lamp to make the sensor, the car model is equipped with magnets, car driving, reed magnet affected due to closure, so that the signal changes, signal transmission to the microcontroller, the microcontroller through calculation to determine the vehicle's speed and direction, then the front of the vehicle lamp is lit, when after the next sensor, according to the speed, put out lights behind the vehicle. The experimental results showed that the model runs device, the front 10 cm away from the lamp lights, the front through the lamp 5 cm when the lamp is off, the number of lights between the lights at 1-4 can be manually adjusted, it can automatically adjust, the faster the speed the number of bright lights more. The system basically achieve the design objectives and requirements, using design ideas and design methods can be extended to hospitals, warehouses and other needs "in light, people take the lights off," the same occasion, as well as other similar product development provide reference .
