Smart street light is a kind of intelligent street light system based on Internet of Things (IoT) technology, which can realize intelligent management and control of street lights through sensors, communication technology, cloud computing, and other technical means. Its technical principles mainly include the following aspects:
1. Sensor Technology: A smart street light system realizes the perception and data collection of the surrounding environment by installing various sensors, such as a light sensor, a temperature sensor, a humidity sensor, a human infrared sensor, etc.
2. Communication Technology: The smart street light system transmits the collected data to the cloud for processing and analysis through wireless communication technology, such as cellular network, LoRa, NB-IoT, etc.
3. Cloud Computing Technology: The smart street light system processes and analyses the collected data through cloud computing technology to achieve intelligent management and control of street lights.
4. Control Technology: Smart street light system through the controller, to achieve the remote control and management of street lights, such as adjusting the brightness, switching lights, timer switch, etc..
Smart street light contains mainly the following aspects
1. Perception Layer: Including various sensors, such as light sensors, temperature sensors, humidity sensors, human infrared sensors, etc., used to sense changes in the surrounding environment.
2. Transmission Layer: Includes wireless communication technologies such as cellular networks, LoRa, NB-IoT, etc., which are used to transmit the collected data to the cloud for processing and analysis.
3. Cloud Computing Layer: Includes cloud computing technology, which is used to process and analyse the collected data to achieve intelligent management and control of street lights.
4. Application Layer: Including controller and management platform, used to realise remote control and management of street lights, such as adjusting brightness, switching lights on and off, and timer switching. At the same time, it can also be used to achieve fault warning and maintenance management of street lights through data analysis and mining.
Smart street light systems are redefining urban illumination through organic integration of IoT technologies. From environmental sensing to cloud-based decision-making, this system not only achieves precise light control, but also provides foundational support for smart cities through data synergy. When each street light becomes a node in the urban sensory network, we’re witnessing not just an energy-efficient lighting upgrade, but new possibilities for harmonious coexistence between people and cities.
