Network system framework of low altitude target detection sensor

Abstract

The invention relates to a network system framework of a low altitude target detection sensor, which comprises a double-layer strip sensor network and a backbone transmission layer network. The outer layer of the double-layer strip sensor network is a network formed by voice sensing nodes which conducts multi-node data fusion and dispersed cooperative data processing to the sensed voice data and guides optical sensing nodes at the inner layer to precisely position and trace a target according to a processing result. The inner layer of the double-layer strip sensor network is a wireless network which can communicate with the voice sensing nodes of the outer layer; the wireless network is formed by the optical sensing nodes; and when the signals of the voice sensing nodes of the outer layer are received, the optical sensing nodes of the inner layer are started and collects the optical information of the target. The backbone transmission layer network is a network used to connect the optical sensing nodes of the inner layer of the double-layer strip sensor network with a command center. The network system framework of the low altitude target detection sensor can make up the disadvantages of a monitoring system which takes radar as a main part in the prior art.

Description

technical field [0001] The invention relates to the technical field of sensor networks, in particular to a low-altitude target detection sensor network architecture based on acousto-optic collaboration. Background technique [0002] With the rapid development of our country's national economy, the aviation field presents an unprecedented development situation. On November 14, 2010, the State Council and the Central Military Commission of China issued the "Opinions on Deepening the Reform of my country's Low-altitude Airspace Management", making deployments for deepening the reform of low-altitude airspace management, which brought opportunities for the development and rise of my country's general aviation. It also poses new challenges to the management of low-altitude airspace. [0003] At present, the detection and management of low-altitude airspace mainly rely on radar surveillance systems. However, radars have low-altitude surveillance blind spots and the system is compl...

Problems solved by technology

[0003] At present, the detection and management of low-altitude airspace mainly rely on radar surveillance systems. However, radars have low-altitude surveillance blind spots and the system is complex. Therefore, it is urgent to develop a new type of lightweight sensor surveillance system for low-altitude and ground-based surveillance systems to make up for the current radar-based surveillance. system deficiencies
