Aiming at the shortcomings of the web software about loop closing and calculation of distribution network in real-time and accurate, a novel software is proposed based on the mobile Internet. It bases on the web software and combines with the mobile internet, which not only can inspect loop closing on the task list’s lines in anytime and anywhere, but also can modify the distribution network’s data. It expounds the design ideas of system in hardware and software architecture, emphasizes some core technology of the system and explains the implementation of the principle of related technology which includes data transfer and data security. The system can meet the needs of the practical engineering, is greatly convenient to power operating personnel work and have well development prospect.
