Sensor "sensing" the weather "Smart streetlight" automatic switch

When the weather is bad, how can the visibility on the road be low during the day? The street lighting management department of the Harbin Municipal Construction and Construction Commission used the “smart street lamp” information system to deliver electricity in the evening and delay the lights in the morning to increase visibility on the road. At present, this “wisdom street light” information system has covered most of the street in Harbin, and the street lights have changed every day.

According to briefings, last year, the street lighting management department of the Harbin Municipal Committee for Housing and Urban-Rural Development utilized modern technology such as the Internet of Things, cloud computing, and the Internet to create tailor-made smart street lamps with remote control, real-time monitoring, fault alarm, facility security, and performance evaluation functions. Information system. The person in charge of the Harbin Municipal Housing and Construction Committee told that the system can automatically recognize the light level and activate emergency lighting through a light sensor placed on the street light. In addition to low visibility, automatic early delivery of electricity in the evening and delay of light off in the morning can be implemented. This system also includes geographical and meteorological factors such as latitude and longitude in Harbin. Under normal weather conditions, the daily opening and closing time of street lamps depends on the conditions of sunshine. It is about 3 minutes before and after the two days before and after, which is more scientific and more humanized than the “one size fits all” style switching lights in the past winter and summer.
