Comprehensive humidity detection system

Abstract

The invention discloses a comprehensive humidity detection system, especially to a comprehensive humidity detection system for grain detection. A remote monitoring analysis management platform is adopted to monitor the water content of grain in a grain bin, and a sampling procedure is not needed, so the workload of grain monitoring is minimized and the labor cost is reduced. Large apparatuses with complex structures are not needed, so the detection cost is reduced. The system is capable of automatically identifying the position of a detection terminal in the grain bin, a manual system input step and other steps are minimized, the intelligent level of the system is improved, and grain monitoring is more convenient and accurate.

Description

technical field [0001] The invention relates to a detection system, in particular to a comprehensive humidity detection system for grain detection, which belongs to the field of analysis and detection. Background technique [0002] Food is not only the strategic resource of the country, but also the basic material to ensure the normal life of the people; food security is the foundation of national security, and maintaining a certain amount, variety and quality of food reserves is a necessary measure to ensure national food security. [0003] Grain moisture detection is of great significance to grain purchase, transportation, storage, and processing trade. Excessive moisture wastes transportation capacity and storage capacity, promotes vigorous life activities of grain and oil, and easily causes grain heating, mildew, insects and other biochemical changes, which can cause huge losses. The grain moisture is too low, which reduces the grain weight and affects the grain quality...

AI Technical Summary

Problems solved by technology

1. Sampling-type testing instruments, such as infrared and halogen heating weighing heavy-duty instruments, cannot achieve continuous online detection and unattended operation

2. On-line instruments based on capacitance and microwave detection principles have complex structures and high costs, and cannot be densely arranged in grain piles

3. The humidity detection probe is connected to the computer in the monitoring room through a cable. This wired connection installation process is complicated, the cost is high, and the equipment maintenance is difficult

4. The equipment that uses the wireless method to detect the humidity of the stored grain is mainly inserted into the interior of the grain for detection through the probe. This method can only detect the humidity of the grain at a local location. The coverage and area of ​​the detection are very limited and cannot accurately reflect the entire internal environment. Humidity, so there are significant limitations

However, the invention does not clearly point out the specific working method of the information collection module, and cannot accurately reflect the humidity of the entire internal environment
