Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a global granary environmental fusion monitoring system and a monitoring method thereof. Background Art

[0002] In the grain storage work in the granary, the monitoring of the grain storage environment, such as pest information monitoring, temperature and humidity information monitoring, nitrogen concentration information monitoring, etc., is an important factor affecting the storage time and storage quality of grain.

[0003] The applicant's previous applications for devices for monitoring the grain storage environment in grain silos, such as a monitoring method for a grain storage temperature monitoring system based on temperature difference disclosed in the application document with application number CN202410773824.6, and an inspection method for a full-depth grain silo environment and automatic pest inspection device disclosed in the application document with application number CN202410620680.0, both use vertical monitoring to achieve overall monitoring of the grain silo environment. However, this monitoring method is only applicable to grain silos with smaller specifications (diameters). When the diameter of the granary is larger, global environmental monitoring cannot be achieved, resulting in certain deviations in the monitoring results.

[0004] Another example is a monitoring system for a granary environment monitor disclosed in an application document with application number CN202311557110.3 in the patent library, which drives the vertical movement of the lateral adjustment cylinder through the action of the No. 1 reciprocating screw, and drives the lateral movement of the detector through the action of the No. 2 reciprocating screw, so as to realize the electric adjustment of the detection position. However, the above-mentioned detection method, on the one hand, because its lateral adjustment cylinder is connected to the No. 1 screw nut at a single end, and a sealing box is provided on the lateral adjustment cylinder, the lateral adjustment cylinder has a large travel resistance. Especially when the diameter of the granary is large, it will be difficult for the two ends of the lateral adjustment cylinder to achieve synchronous movement, and there may even be a risk of deformation or breakage. On the other hand, because the No. 1 reciprocating screw and the No. 2 reciprocating screw move once, they can only complete the environmental monitoring of a single position, and the lateral adjustment cylinder is driven at a single end, which will result in a large diameter of the granary. When there are many monitoring positions required, the monitoring work will require a lot of time to complete. Summary of the invention

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a global granary environment fusion monitoring system and a monitoring method thereof.
