基于互联网技术的智能路灯系统Intelligent Street Lighting System Based on Internet Technology

技术领域technical field

本发明涉及一种路灯系统，具体地，涉及一种基于互联网技术的智能路灯系统。The present invention relates to a street lamp system, in particular to an intelligent street lamp system based on Internet technology.

背景技术Background technique

路灯是城市照明系统的重要组成部分。黑夜中为道路带来光明的同时也消耗着巨大的能量。目前城市中使用的路灯照明系统虽然普遍能够根据白天黑夜的时间或光照强度实现路灯的自动开关。但是在不同时间段上，道路对路灯灯光的需求并不完全一致，比如道路交通高峰时间段，需要比较亮的灯光，而深夜时段，道路上交通量小，过强的路灯也会消耗大量的能源，也会影响人们的休息，可以适当降低路灯灯光亮度。随着季节变化，节日庆典等各种突发情况，路灯亮度需求变化的时间会经常发生变化，用一个统一的时间控制路灯的开关和亮度远远不能满足智能照明的需求。目前大多数路灯的开关和亮度控制一旦设定以后通常不能更改，或者需要工人在现场断电，手工操作更改，同样，一旦设定好了也不便于更改设置。不能满足各种特殊情况下对路灯开关，亮度调节的需求。从能耗的角度看，在实际使用路灯的时候，新旧路灯或者不同季节下路灯通过相同大小的电压和电流时，其产生的亮度是不一样的，过亮的灯光实际上是能量的浪费。有时当路灯发生故障时，电路仍然接通，也造成了能源的浪费。Street lights are an important part of urban lighting systems. Bringing light to the road in the dark also consumes huge energy. Although the street lamp lighting system used in the city generally can realize the automatic switch of street lamp according to the time of day and night or light intensity. However, in different time periods, roads have different requirements for street lights. For example, during peak hours of road traffic, brighter lights are needed, while in the middle of the night, the traffic volume on the road is small, and excessively strong street lights will also consume a lot of energy. Energy consumption will also affect people's rest, and the brightness of street lights can be appropriately reduced. With seasonal changes, festivals and other emergencies, the time for changing street lamp brightness requirements will often change. Using a unified time to control the switch and brightness of street lamps is far from meeting the needs of intelligent lighting. At present, the switch and brightness control of most street lamps usually cannot be changed once they are set, or workers need to cut off the power on site and change them manually. Similarly, it is not easy to change the settings once they are set. It cannot meet the needs of street light switches and brightness adjustment in various special cases. From the perspective of energy consumption, when street lights are actually used, new and old street lights or street lights in different seasons pass through the same voltage and current, and the brightness produced is different. Excessively bright lights are actually a waste of energy. Sometimes when the street lamp breaks down, the circuit is still connected, which also causes a waste of energy.
