Solution for temperature and humidity monitoring of granary

Solution for temperature and humidity monitoring of granary
1、 Programme background
grain yield
As a big country, the total grain output in 2020 will be 669.49 million tons (1339 billion kg), an increase of 5.65 million tons (11.3 billion kg) or 0.9% over 2019. According to incomplete data, in addition to the stored grain purchased by the state, more than 60%~70% of the grain is stored in the households of farmers, and the grain loss caused by improper storage methods of farmers accounts for about 8%~10% of the total stored grain. This not only affects the production income of farmers, but also threatens the security of China’s grain reserves.

Grain Storage
The security of grain storage has always been a complex and important issue. During grain storage, the serious loss is mainly caused by the change of climate, environment, ventilation conditions and other factors, which leads to the change of temperature and humidity in the granary, and the generation of gases and microorganisms that are not conducive to grain storage.
Granary management
One of the key points of granary management is to reasonably arrange the temperature measuring points, because the granary needs to check the temperature changes frequently, so as to find the hot spots in the granary in time and reduce the loss of grain in time. However, the heat transfer of the grain pile is relatively slow, which makes people feel very bad. Managers need to often enter the stuffy and choking granary to check the temperature and humidity of the grain pile, and constantly carry out heavy physical labor such as turning the granary and ventilation. This not only does great harm to the human body, but also is unscientific and untimely. Therefore, the situation of grain moth eaten and mildewed often occurs. In this regard, Jianda Renke launched a granary temperature and humidity monitoring solution to solve such problems.
2、 Scheme introduction
GPRS wireless temperature and humidity sensor is an industrial temperature and humidity sensor transmitted by GPRS wireless. Use the GPRS wireless network of China Mobile or China Unicom to send remote sensor data to the centralized monitoring center. There is no distance limit. You can monitor only where there is a mobile or Unicom network. Or use the RJ45 network port of APEM6500 to collect data in the data center, which is convenient and reliable for installation and debugging. The product covers the common functions required for power environment monitoring. It can be configured flexibly and quickly according to the specific requirements of different applications.
