In order to effectively monitor LED street lamp, an intelligent monitoring system of LED street lamp network based on Power Line Carrier Communication (PLC) technology is proposed. Based on Ant Colony Algorithm (ACA), this paper develops an LED street lamp networking addressing algorithm suitable for low voltage distribution network and optimizes the calculation of objective function, rules of updating pheromone, state transition rules and search. The automatic routing model of street lamp is designed and the framework of automatic routing protocol is given. The channel quality of low-voltage distribution network can be dynamically identified and the routing of PLC network can be dynamically maintained to ensure the effectiveness of the communication network. Through the channel simulation model and field test, the effectiveness and feasibility of the proposed method are verified.
