The invention relates to a method and system for data preprocessing of the Internet of Things. The system includes: a user authority verification module, which checks the access legality, and according to the authority configuration file, grants the corresponding authority to the access subnet or the user, rejects Illegal access requests ensure the access security of the IoT server; the data and event filtering module, according to the data filtering configuration file, only retains the sensor data and event notifications that meet the requirements, and discards garbage data; and checks the validity of data and events The module, according to the validity configuration file, checks the validity of the data item by item and performs the prescribed preprocessing operation; after the data preprocessing, save the legal data to the database. The method of the invention is simple and can reduce the error rate of the system.
Description
technical field [0001] The invention relates to a method and system for data preprocessing of the Internet of Things. Background technique [0002] The Internet of Things is a self-organizing network composed of devices in a small area using a specific network protocol. The center of the Internet of Things is a convergence node, which generally has the ability to connect to an external public network (Internet, etc.). The Internet of Things mainly solves the problem of networking of isolated devices. The networking does not depend on the public network, and generally forms a self-organizing proprietary network. If the Internet of Things needs to be deployed on a large scale, the general method is to use the Internet of Things to network on a small scale, and then the convergence node of each Internet of Things subnet is connected to the central server to form a cross-regional deployment network. [0003] The Internet of Things is a fragile network. The Internet of Things su...
