Electric power Internet of Things block chain data management system

The invention provides an electric power Internet of Things block chain data management system. The system comprises an Internet of Things data acquisition terminal and a management terminal. The Internet of Things data acquisition terminal is provided with an information acquisition module, an information sending module and a data encryption module; the information acquisition module is used foracquiring Internet of Things data of the power equipment; the data encryption module is used for encrypting the Internet of Things data to obtain an Internet of Things data ciphertext; the informationsending module is used for sending the Internet of Things data ciphertext to each node in the block chain to judge the legality of the Internet of Things data: if the Internet of Things data ciphertext is legal, splitting the Internet of Things data ciphertext into a first ciphertext and a second ciphertext, and calculating a digital abstract of the Internet of Things data to obtain an abstract M1, rearranging all charact
