Background The current grain condition monitoring technology has obvious limitations, and is mainly embodied in the aspects of monitoring range and function. On the one hand, although the mobile monitoring equipment is convenient for temporary deployment and surface inspection, only basic data such as temperature and humidity on the surface layer of the grain pile can be acquired, and the inside of the grain pile can not be effectively detected, so that key changes such as deep grain condition state and the like are not well mastered, and the accuracy of comprehensively evaluating the grain storage safety is limited. On the other hand, although the fixed type deep monitoring system can be embedded into the grain pile through the embedded sensor, the function is single, the system is usually only focused on the acquisition of temperature and humidity parameters, the monitoring capability of biological indexes such as insect pest activities and mildew signs is lacked, the equipment is fixed for a long time after grains are taken into a warehouse, the monitoring point position cannot be adjusted according to grain condition changes or storage requirements, and the flexibility and the adaptability are poor. These defects make the prior art difficult to provide multidimensional grain condition information, increase management difficulty of risks such as grain storage mildew, insect damage and the like, and restrict intelligent development of grain storage. In order to cope with the challenges, the grain condition monitoring field is in urgent need of firstly realizing deep monitoring in a grain pile, breaking through the limitation of surface detection to grasp the state change of each layer of the grain pile in real time, secondly, monitoring information is more comprehensive, multi-parameter data such as temperature and humidity, gas components (such as carbon dioxide and oxygen concentration) and pest quantity are integrated, and collection and analysis are carried out through a unified platform so as to make grain condition early warning, meanwhile, monitoring equipment is required to have flexibility and support movable and adjustable deployment modes so as to adapt to different grain bin structures, storage stages and emergent grain condition events, and in addition, along with the progress of Internet of things and big data technology, the intelligent and informatization of the monitoring equipment also become core requirements including functions such as real-time data uploading, intelligent early warning analysis and remote control so as to improve management efficiency and decision level. Therefore, in order to overcome the shortboards in the prior art, it is urgent to develop a grain condition integral monitoring system, which integrates internal multidimensional sensing, flexible layout mechanism and intelligent information processing, so as to realize full coverage, high precision and dynamic management of grain condition monitoring and ensure grain storage safety and quality.
