1. Project background

Food production

China is a big food consumer. In 2020, the country's total grain output is 669.49 million tons (1.339 billion catties), an increase of 5.65 million tons (11.3 billion catties) from 2019 , An increase of 0.9%. According to incomplete data, in addition to the state-purchased grain reserves, more than 60% to 70% of my country's grain is stored in farmers' homes, and the loss of grain due to improper storage methods of farmers accounts for about 8% to 10% of the total grain stock. This not only affects farmers’ income, but also threatens the security of our country’s grain reserves.

Grain storage

The security issue of grain storage has always been a complex and important issue. During the grain storage period, the main cause of serious loss is due to changes in climate, environment, and ventilation conditions, which lead to changes in the temperature and humidity inside the granary, resulting in gas and microorganisms that are not conducive to grain storage.

Granary management

One of the key points of granary management is to arrange temperature measurement points reasonably, because the granary needs to check temperature changes frequently to facilitate the timely detection of the heating points of the granary and reduce the loss of grain in time. However, the heat transfer of grain piles is relatively slow, which makes people feel extremely poor. It requires managers to often enter the muggy and choking grain bins to check the temperature and humidity of the grain piles, and constantly carry out heavy manual labor such as turning the bins and ventilating. It is extremely harmful to the human body, and it is unscientific and untimely. Therefore, grain moth-eaten and mildew often occur. In response, a solution for monitoring the temperature and humidity of the granary was introduced to solve such problems.

Two. Introduction to the program

The program is mainly composed of GPRS-C3 temperature and humidity transmitter and monitoring software.

The solution is based on GPRS/4G transmission of monitored temperature and humidity data, and the collected temperature and humidity data is uploaded to the server through the network base station. The monthly flow of GPRS communication is less than 30M. The device is connected to our free cloud platform, and two upload methods are optional. Realize the control of temperature and humidity change data in the warehouse anytime and anywhere, so that users can adjust the temperature and humidity in the warehouse in time according to the monitoring data to ensure a suitable environment for grain storage.
