Abstract: Under the background of energy internet，due to the access of massive sensor nodes，the amount and types of data in energy internet have increased dramatically，and centralized data processing has a great impact on the updating of substation drawing model. Therefore，a control measure of automatic updating of substation

drawing model based on cloud-fog-edge collaboration was proposed. Interval rules and storage rules were set，the

fog layer was reset，and the three-layer configuration of application layer，fog layer and cloud layer was adopted to

handle data calculation between the application layer and the central cloud node. The fog-end calculation can

replace all or part of the functions of cloud computing，thus effectively reducing the performance requirements of

computing equipment for automatic updating of graphics models. On this basis，the cloud data was redistributed，

and different levels of pheromones were automatically updated，so as to complete the automatic updating control of the substation drawing model. The experimental results show that，with the application of the research method，the information carrying capacity is still higher than 1 000 kbit when the number of visits to information collection

points increases，and the average execution time of this method in the experimental process is always less than 0.4 s.Experimental results show that this method can keep stable data update and stable output under the condition of

significant increase in data volume.
