In the city the night,roads are lit on both sides of the street intensive but neat,looks like a dragon fly,although this is a beautiful landscape,but many times the light of these lamps are wasted,because a large part of the time,the road is empty,this situation is particularly mon in the economic and the traffic is not very developed area.The enormous waste of power resources has a negative impact on the economy of these areas.Then,is there an automatic control device that is convenient for pedestrians and vehicles at night and saves energy? Saving energy is actually reducing energy losses as much as possible.On the remote roads,traffic is very little,and long hours of street lights,no matter whether there are vehicles or vehicles,pedestrians or pedestrians,have caused great waste of energy.Even if there is a vehicle passing,should not all line lights are on,should only in the vehicle within the effective range of the street light,otherwise it will cause great losses!Pedestrian walking on the road is the same,only in the pedestrian walk within the corresponding range to open the street lamp,to meet the needs of lighting.How can I _ if someone is in the street? We can use an instrument that lights the street automatically when someone or a car is in the street.Then the sensor does not produce air through sound vibration control,but through the vehicles and pedestrians on the road impact and pressure caused by pavement vibration control,the two kinds of vibration is different,otherwise it will be a strange bination of circumstances might be animal sounds,and the roar of the road outside lights,the same as not to the purpose of saving energy.If the noise made by the traffic or pedestrian is too small,the light wont turn onThen,in name only,it doesnt work.Car driving,pedestrian walking,will naturally impact on the ground and pressure,so that the road vibration,which can use the vibration of the road to control whether the street lights bright or extinguished.The device uses shock and pressure vibrations to control the street lights,which can be a good source of energy savings.
