The present invention belongs to the technical field of electric power Internet of things, specifically a data transmission system of electric power Internet of things, including a cloud platform and a node end; the cloud platform runs in the cloud network and keeps connected with the node end through the network; the node The terminal is a power equipment terminal connected to the network with the Internet of Things function; the node terminal includes an encryption module; the cloud platform includes a database and a verification module; after the cloud platform receives the data uploaded by the node terminal, The data is verified by the verification module. After the verification is passed, the cloud platform performs data processing on the data and saves it in the database; if the data verification fails, the cloud platform determines that the data is invalid and discards the data; It guarantees the security of data and prevents the transmitted data from being tampered with. At the same time, it has a certain ability to resist network attacks.
Description
technical field [0001] The invention belongs to the technical field of electric power Internet of Things, and specifically relates to a data transmission system of electric power Internet of Things.
