Abstract:

This paper aims at intelligent and effective supervision of light emitting diode (LED) street lamp network to reduce energy consumption,and puts forward an LED street light monitoring system based on power line communication (PLC) technology.A suitable low-voltage distribution networ k of LED lights for communication is set up based on ant colony algorithm (ACA),and the opt imization objective function,searching rules,rules of pheromone update and state transit ion are improved.The automatic routing model of street light is established,and the automatic routing protocol framework is given.With this model,the channel quality of the low voltage distribution network can be dynami cally identified,and according to the channel quality changes,the power line com munication network routing is dynamically maintained,the effectiveness of the communication network is ensured.Finally,the established simulation model and experimental study are used to verify the feasibility of the m ethod.
