Granary monitoring method, device, equipment and system based on radar offset imaging

Abstract

The invention provides a radar migration imaging based granary monitoring method, device, equipment and system. The method includes the following steps: successively sending a polling control signal to each radar node in a radar array containing N radar nodes, wherein only one radar node receives the polling control signal at the same time, the radar node currently receiving the polling control signal is a signal emission node to emit a detection signal to granary storage areas so as to generate reflected signals, and other N-1 radar nodes receive the reflected signals; obtaining interface information between different electrical parameters of local grain the current granary storage area according to the reflected signals, grain electrical parameters and migration imaging principles of theother N-1 radar nodes; obtaining a grain layered structure at that moment according to M grain layered structures obtained by M rounds of polling after the M rounds of polling are finished; and obtaining the local change information of grain structures according to the grain layered structure at that moment and the grain layered structure at last moment so that the monitoring of granaries can berealized.

Description

technical field [0001] The invention relates to the field of information communication technology, in particular to a granary monitoring method, device, equipment and system based on radar offset imaging. Background technique [0002] Food is the basic demand of the national economy and the people's livelihood, and its supply and demand balance, market stability and other factors directly affect the security, stability and development of the country. Therefore, how to ensure the long-term safe storage of grain has become a major event of national concern. For the storage of grain, it is not only necessary to control the natural environmental conditions such as the temperature and humidity of the storage granary, but also the supervision and monitoring of the granary is also a focus and difficulty that needs to be paid attention to. Due to the large amount of grain stored in the granary, which contains huge economic benefits, various violations of laws and regulations, such ...

Problems solved by technology

However, monitoring the moisture content of grain through the principle of ground penetrating radar can more accurately explain the quality change of grain, but it does not pay attention to the relationship between grain electrical parameters and other factors. Radar movement conducts segmented grain monitoring, which has high requirements for the accuracy of device installation and the stability of system operation
