Embodiment 1

[0047] In an exemplary embodiment, a method for data collection and transmission based on multi-hop cooperation is provided, such as figure 2 As shown, the method includes:

[0048] collecting spectrum data through different nodes, and performing signal-to-noise separation on the spectrum data to obtain collection signals;

[0049] Establishing a set of local signal libraries in different nodes respectively, and classifying the collected signals;

[0050] Comparing the signal libraries of different nodes respectively, the data to be transmitted is obtained, and the redundancy of different nodes is compared, so that the data to be transmitted is transmitted from a node with a low redundancy level to a node with a high redundancy level;

[0051] After the data transmission is successful, update the signal library of different nodes respectively.

[0052] Further, the different nodes include a monitoring center node, a fixed anchor node, a dedicated mobile node and a general m...

Embodiment 2

[0056] Based on embodiment 1, a specific implementation scheme is provided, specifically, as Figure 4 As shown, firstly, data collection is carried out, and the signal library and data classification are constructed to classify the collected signals, including:

[0057] Compare the collected signal with the local signal library. If there is no abnormality in the characteristics of the collected signal, it will be classified as a whitelist signal, which is a legal signal. If the collected signal is an illegal sensitive signal, it will be classified as a blacklist signal. If the collected signal is unknown signals are classified as gray list signals. Then maintain a set of local signal libraries on each node.

[0058] Furthermore, compare the signal found in each collection with the local signal library, if it is a whitelist signal, ignore it and not store it; if it is a blacklist signal, record all the original signal data, including spectrum, audio and direction, etc. , add...

[0078] In an exemplary embodiment, the present invention also provides a data collection and transmission system based on multi-hop cooperation, the system comprising:

[0079] multiple nodes;

[0080] An acquisition module, configured to acquire spectrum data at different nodes, and perform signal-to-noise separation on the spectrum data to obtain acquisition signals;

[0081] Local signal libraries located in different nodes;

[0082] The comparison module is used to compare the signal libraries of different nodes, obtain the data to be transmitted, and compare the redundancy of different nodes;

[0083] A data transmission module, configured to transmit data to be transmitted from a node with a low redundancy level to a node with a high redundancy level;

[0084] The data update module is used to update the signal libraries of different nodes after the data transmission is successful.

[0085] Further, the data transmission module includes wireless sensors arranged betwe...

Abstract

The invention discloses a data acquisition and transmission method and system based on multi-hop cooperation, and belongs to the technical field of communication, and the method comprises the steps: collecting frequency spectrum data through different nodes, and carrying out the signal-noise separation of the frequency spectrum data, and obtaining a collection signal; respectively establishing a set of local signal libraries in different nodes, and classifying the acquired signals; respectively comparing the signal libraries of different nodes to obtain data to be transmitted, comparing the redundancy of the different nodes, and transmitting the data to be transmitted from the node with the low redundancy level to the node with the high redundancy level: after the data transmission succeeds, respectively updating the signal libraries of the different nodes. According to the method, collected signals are classified for differential collection, only interested sensitive signals are collected, multi-hop transmission is carried out among nodes by using a hill-climbing search algorithm, and the problems of insufficient node storage capability and narrow transmission bandwidth are solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data collection and transmission method and system based on multi-hop cooperation. Background technique [0002] In the environment where mobile communication signal coverage is insufficient in remote areas, using a monitoring network composed of fixed nodes and mobile nodes, some monitoring data or environmental collection data need to be sent back to the command center, such as figure 1 As shown, the current method is to use the satellite Internet and the 4G network as mutual backups for data return, but the radio monitoring data has a large amount of spectrum data due to the wide frequency band of collection. Insufficient bandwidth of satellite communication, real-time data transmission in full frequency band cannot be realized, and the storage capacity of mobile data collection nodes is limited, making data collection and storage an important bottleneck, whic...
