Local fault location and adaptive shielding system and method for Internet of Things

Abstract

The application discloses a local fault location and adaptive shielding system for Internet of Things (IoT), including: a plurality of management and maintenance local area network grids and a network-wide fault management center, wherein the plurality of management and maintenance local area network grids and the network-wide fault management center are in communication connection; the managementand maintenance local area network grids are used to locate the IoT nodes and monitor the abnormal state of the IoT nodes, and send the location information and abnormal status information of the abnormal IoT nodes to the network-wide fault management center when there are abnormal IoT nodes existing in the management and maintenance local area network grids; the network-wide fault management center is used to receive the location information and abnormal state information of the abnormal IoT nodes, and shield the abnormal IoT nodes and data thereof. The application divides the IoT nodes intomultiple regions, and performs positioning and anomaly detection on the IoT nodes in each region, which facilitates the discovery and location of the IoT fault, saves maintenance time and energy, andthus ensuring the information collection accuracy of IoT.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a system and method for local fault location and adaptive shielding of the Internet of Things. Background technique [0002] With the development of the Internet of Things technology, a small building, a medium to a community, and a large city are forming various sensors with wireless communication functions (such as temperature sensors, humidity sensors, light sensors, air particle sensors, etc.) ) and functional facilities (such as access control, air conditioning, heating equipment, lamps) and other network nodes are connected to each other to form a wide area network. [0003] On the one hand, each network node in the Internet of Things performs its own functions, and on the other hand, it continuously or intermittently generates node data as a data source. For example, network nodes of various sensor types are used to sense the state of the surr...
