The invention discloses a multi-granary monitoring system for detecting the moisture content of stored grains based on WSN microwave, which comprises a microwave transmitting device, a microwave receiving device, a wireless transmission device and a detection control device, and is characterized in that the microwave transmitting device is used for transmitting microwave signals to the grains, and the microwave signals are reflected after passing through the grains; the microwave receiving device is used for receiving microwave signals reflected by grains, the wireless transmission device is in signal connection with the microwave receiving device, the wireless transmission device is used for converting the microwave signals of the microwave receiving device into data signals and further used for outputting the data signals, and the detection control device is in signal connection with the wireless transmission device. And the detection control device is used for receiving the data signal output by the wireless transmission device and detecting and analyzing the data signal. The multi-granary monitoring system can realize more accurate detection of the moisture content of grains.
Description
technical field [0001] The invention relates to the technical field of microwave applications, in particular to a multi-granary monitoring system based on WSN microwaves for detecting moisture content of stored grains. Background technique [0002] On the premise of ensuring people's livelihood needs, we store excess grain in large granaries for emergencies. During storage, changes in the internal moisture content of grains lead to grain losses. Therefore, the accurate detection of grain moisture content in the granary is of great significance for grain storage. Existing methods for detecting grain moisture content include direct method, capacitive method and resistance method, but the above-mentioned methods are inaccurate in the detection results of grain moisture content. Due to its special storage conditions, the grain storage silo needs to fumigate the grain. Therefore, the arrangement of wired equipment in the granary should be minimized to avoid loss and damage. Th...
