Problems solved by technology

The system applies the wireless sensor network to the grain situation monitoring system of the granary, which has made great progress compared with the traditional wiring form, but all nodes in the system are wireless nodes, which has its shortcomings
Radio waves will attenuate when propagating in grain, thus affecting the accurate transmission of grain parameters, and the design of nodes does not involve the design of specific sensors

Abstract

The invention provides a sensor network grain situation monitoring system based on a bus and a wireless structure, which can monitor grain situation information in a granary such as temperature, humidity, grain moisture and insect damage in real time. The monitoring system consists of grain situation parameter monitoring nodes which are buried into grains in the granary, relay nodes on a grain surface layer in the granary, and granary main control nodes, wherein a plurality of grain situation parameter monitoring nodes are connected and communicated with each other through a bus-organized structure and the relay nodes which are arranged on the top layer, and the relay nodes are communicated with the main control nodes for managing the granary through a wireless network; and the grain situation monitoring nodes are responsible for acquiring grain situation parameters in the granary such as the temperature, the humidity, the grain moisture and the insect damage, and the grain situation parameter information acquired by various monitoring nodes is transmitted to the granary main control nodes through the relay nodes on the top layer.

Description

technical field [0001] The invention relates to the technical field of grain storage monitoring, in particular to a grain situation monitoring system based on the combination of a bus and a wireless structure. Background technique [0002] As the saying goes: "Food is the most important thing for the people." Human survival is also inseparable from food. The food issue is related to the development of society and the stability of people's lives. However, under certain conditions, such as high temperature, high humidity and other environmental conditions, grain is easy to mold. If it is not treated in time, the grain will go bad and deteriorate. Moldy grains, grains that have changed their taste, and seed grains that do not germinate will lose their original use value and cause serious economic losses. Therefore, the storage of grain has become very important. [0003] During the storage of grain, changes in grain conditions such as temperature, humidity, moisture, and inse...
