The invention provides a ubiquitous power internet of things intelligent management system. The ubiquitous power internet of things intelligent management system comprises an equipment terminal and amanagement terminal, the equipment terminal is provided with an information acquisition module and an information sending module; the information acquisition module is used for acquiring Internet of Things data of the equipment terminal; and the information sending module is used for sending the Internet of Things data to each node in the blockchain network to judge the legality of the Internet ofThings data, and if the Internet of Things data is legal, writing the Internet of Things data into the management terminal and the blockchain respectively. Internet of Things data is sent to each node in a block chain network to carry out legality judgment of the Internet of Things data; and if the Internet of Things data is legal, writing the Internet of Things data into a management terminal and a block chain to prevent data loss or change, thereby preventing the normal life of people from being influenced by power grid data management breakdown if the terminal fails in a traditional structured center mode, and ensuring the normal operation of a power grid.
