In order to meet the needs of safety control and construction quality control of construction network construction work, and effectively improve the management and control ability of distribution network engineering field work, this paper combines the power distribution engineering site management technology with wireless handheld terminal technology and proposes power distribution. Network engineering site management and control of the overall architecture design of the handheld terminal system. The distribution network engineering control APP and support system constructed cover the whole process control of project management, pre-construction, construction process and project completion acceptance. Through the distribution network engineering control APP design proposed in this paper, it can not only discover the safety hazards in the construction site of the distribution network in time, but also effectively avoid the occurrence of safety accidents, and effectively monitor the distribution network project to ensure the distribution network project. The construction meets the requirements of standardization construction. This paper provides a certain theoretical guidance for the construction of China"s ubiquitous power Internet.
