Abstract: Disclosed in the embodiments of the present invention are a security auditing system and a method for same. The security auditing system comprises an eSIM module. The eSIM module is configured to: on the basis of pre-stored auditing rules, perform a security check on each received network connection request; if the security check is passed, determine said network connection request to be a legitimate request and allow the main control terminal that sent the network connection request to perform mobile network connection; and if the security check is not passed, determine the network connection request to be an illegitimate request and prohibit the main control terminal that sent the network connection request from performing mobile network connection.

Abstract: This invention provides a cooperative coverage method for distribution network information perception. The cooperative coverage method includes the following steps: construction of connected cooperative coverage sets, which can cover all target nodes with as few information perception nodes as possible, and maintain the connectivity of each cooperative coverage set with connected sets construction methods based on of hierarchical clustering; Cooperative coverage set scheduling, introducing the concept of energy ratio threshold, dividing the life cycle of the system into multiple time slices, calculating the energy ratio of perception device set in each time slice to realize the set scheduling. The invention realizes the efficient utilization of the energy of the perception device through the construction and scheduling of the connected coverage set in different time slices, and improves the use efficiency of the information perception network.
