During the storage period, the grain starts to condense when the humidity reaches the saturation point, followed by fermentation and local temperature rise, which in turn prompts the grain to release moisture and accelerate the corresponding fermentation process. When the ambient temperature rises, the dust and impurities in the grain, especially organic impurities, accelerate the above process, seriously threatening the safety of grain storage and leading to grain decay.

In recent years, China's grain storage technology has developed significantly, and can automatically monitor the grain situation, temperature and humidity in the grain silo, and can link with the heating, cooling, dehumidification, ventilation and other equipment in the grain silo, control the heating, cooling, dehumidification, ventilation and other equipment to work, but also according to the artificially set value timing control equipment or artificially opened as needed, so that the grain temperature, moisture, the effective concentration and ratio of the gas in the silo to maintain a stable state, to ensure the safety of grain storage

A large state-owned grain silo adopts the intelligent grain silo safety monitoring system solution and related equipment launched by Jinan Xiangkong Control Automation Equipment Co. It conforms to the relevant specifications of the safety monitoring system and meets the demand for safety monitoring.

System composition: online gas concentration detector (carbon monoxide, oxygen), online temperature and humidity detector, armored temperature measurement cable, grain silo environmental safety intelligent main control cabinet, upper computer computer.
