VB-based Small-Granary Monitoring System Design

To realize the convenient collection and processing of data of small granaries, such as internal grain temperature and humidity, the paper designs a kind of real-time collection and monitoring system based on the visual basic environment, and introduces the system’s overall design, information collection function, operating procedure, and data processing. Revolving around the real-time collection and monitoring of temperature and humidity of corn stored in a small granary in the experiment, and in the light of the concise CAE humidity curvilinear equation, the paper establishes the desorption and adsorption window, draws the desorption and adsorption equilibrium curve, and analyzes the temperature and humidity changes of grain in each storing stage so as to achieve the purpose of monitoring. The results indicate that the system can transmit and collect data stably, which is conducive to further improving the storing quality of grain.
