Sensor network safety system based on delaminated intrusion detection

The invention discloses a sensor network safety system based on delaminated intrusion detection, which comprises a safety manager, a network manager, a gateway, a route device and a field device. The sensor network safety system also comprises a local intrusion detection module, an analyzer intrusion detection device and an all-channel analyzer. A user can regulate sleep time duty cycle of the device in the network according to the demand of the local intrusion detection rate to ensure that the local intrusion detection rate meets the demands; a third party detection module based on the all-channel analyzer is used for detecting and analyzing network flow, thus system resource consumption can be reduced; and in a further technical scheme, the flow in the network is predicted through a simple linear prediction algorithm ARMA (Autoregressive Moving Average) model, thus excessive resource consumption caused by local detection in a wireless sensor network can be effectively avoided. Network resources can be more reasonably utilized, network performance is improved, intrusion detection of network accessing equipment is effectively realized, communication treatment of network safety is supported, and normal operation of the network is guaranteed.
