The present invention relates to the field of
grain storage monitoring technology, and specifically to a method and
system for monitoring grain conditions in a
wharf granary. The method comprises the following steps: obtaining data on the environmental characteristics of the
wharf granary and the grain
pile size characteristics, temperature characteristics,
humidity characteristics, and
gas concentration characteristics; constructing a spatiotemporal
feature model based on the data, the spatiotemporal
feature model comprising a temperature spatiotemporal
feature model, a
humidity spatiotemporal feature model, and a
gas concentration spatiotemporal feature model; obtaining spatiotemporal
feature data according to the spatiotemporal feature model;
processing the spatiotemporal
feature data to obtain optimized spatiotemporal
feature data; constructing a food security
risk assessment model through the optimized spatiotemporal feature data; and monitoring the grain conditions in the
wharf granary according to the food security
risk assessment model. The present invention greatly reduces the monitoring cost and achieves high-precision assessment of food security risks by performing internal sensorless monitoring of the temperature,
humidity, and concentration of infinite space points inside the grain
pile.
