Abstract
Based on the analysis of low voltage power line carrier network topology and the characteristics of the communication channel, the concept of splitting the data bus is proposed in streetlight monitoring system. The secondary network bus strategy is adopted to solve the problem of signal relay in the control of streetlights. Because the network topology of the streetlamp control system is a complex and strong transition diagram, the traditional bus monitoring scheme is easily invalidated in the network. In this paper, the problem of optimal path planning in data transmission is realized by using an ant colony algorithm which has a strong adaptive ability.
