In today’s society, food security has always been an important issue related to the national economy and people’s livelihood. With the continuous development of science and technology, Internet of Things technology has come into being, playing an irreplaceable role in granary environmental monitoring and greatly improving the quality and efficiency of grain storage.
From a global perspective, the population continues to grow and the demand for food continues to rise. How to ensure the safety and quality stability of grain storage has become an urgent problem to be solved. Traditional granary management methods often rely on manual inspections, which have many disadvantages. For example, the time interval between inspections may not lead to the timely discovery of the impact of environmental changes on grain, and the accuracy and integrity of manually recorded data are also difficult to guarantee. The emergence of Internet of Things technology has brought new hope for solving these problems.
Real-time monitoring
Environmental parameter monitoring
In a special environment such as a granary, environmental factors have a vital impact on the storage quality of grain. By deploying various sensors in the granary, such as temperature sensors, humidity sensors, oxygen content sensors, etc., accurate monitoring of environmental parameters in the granary can be achieved. In the process of grain storage in the granary, its own respiration and the influence of the external environment will cause changes in temperature, humidity and oxygen content. For example, too high temperature may accelerate the metabolism of grain, causing it to deteriorate too quickly; too high humidity can easily cause grain to mold; too high oxygen content may promote the growth and reproduction of pests.
These sensors can collect data with extremely high accuracy and transmit the collected data to the cloud platform through wireless communication technology. Managers can view the environmental conditions of the granary in real time through mobile phones, computers and other terminals anywhere, whether they are working in the office or on a business trip, and promptly understand every subtle change inside the granary.
Video monitoring
In addition to environmental parameter monitoring, video monitoring is also an important part of granary environmental monitoring. By reasonably arranging network cameras inside the granary, every corner of the granary can be seen.
It is very important to present video data and environmental parameters simultaneously. While checking the environmental parameters, managers can intuitively see the actual situation inside the granary through the video screen. For example, when the temperature sensor shows that the temperature in a certain area is abnormally high, video surveillance can be used to check whether there is any equipment failure in the area, whether the grain is stacked properly, and so on. This provides managers with a richer source of information to fully understand the real-time situation of the granary, enabling them to more accurately judge the status of the granary and take more effective countermeasures.
Intelligent Control
Equipment Linkage
The environment inside the granary needs to be kept in a relatively stable state to ensure the safe storage of grain. The system can be linked with equipment such as air conditioners, door magnets, and lighting systems in the granary. For example, when the temperature sensor detects that the temperature in the granary is too high, the system will automatically issue instructions to the air conditioner to start the refrigeration function and reduce the temperature in the granary.
Similarly, the door magnet system is also interconnected with other equipment. When the humidity sensor detects that the humidity is abnormal, the system may determine whether to open or close the door to adjust the humidity according to the specific situation.If the outdoor air humidity is low, the system can control the door magnetic system to open the door for ventilation and clearing damp; If the outdoor humidity is also high, keep the door closed and start the dehumidifier. The lighting system not only provides lighting functions, but also can automatically adjust the brightness according to the intensity of ambient light and whether there are people in the granary, which not only meets the lighting needs but also saves energy. Through this equipment linkage method, the operating status of the equipment is automatically adjusted according to the changes in environmental parameters, such as heating, cooling, etc., to ensure that the granary environment is always in the best state.
Automatic alarm
In granary environmental monitoring, the automatic alarm function is an important line of defense to ensure food safety. When the environmental parameters deviate from the safety standard or reach the alarm threshold, the system will automatically trigger an alarm notification.
For example, for grain storage, the temperature generally has a suitable range. If the temperature exceeds this range by a certain value, it may have an adverse effect on the grain. When the temperature sensor detects that the temperature reaches the alarm threshold, the system will immediately remind the management personnel to deal with it in time through SMS, phone, email, cloud platform message and other methods. This multi-channel alarm method ensures that the management personnel can receive the alarm information at the first time and take corresponding measures, such as remote control equipment for adjustment or arrange local staff to deal with it, to ensure the safety of the granary.
Data management
Historical data storage
In the process of granary environmental monitoring, the environmental parameters at every moment are very valuable information. The system automatically stores historical data, which is like establishing a detailed “health file” for the granary.
These historical data contain records of various environmental parameters such as temperature, humidity, oxygen content, etc. in different time periods. Taking temperature data as an example, the system may record the temperature values of various areas in the granary every few minutes. As time goes by, a large amount of data will be accumulated. These data are stored in the database of the cloud platform in an orderly manner and can be retrieved and queried through specific algorithms.
In addition, the system can intuitively display these historical data in the form of curves and other forms. By observing the curves, managers can clearly see the changing trends of granary environmental parameters in different seasons and time periods. For example, during the high temperature period in summer, the temperature curve may show a clear upward trend, while the humidity curve may fluctuate with the change of rainfall weather. This helps managers analyze the changing trends of the granary environment and promptly discover and deal with potential problems. For example, if the changing trends of temperature and humidity in a certain period of time are found to be abnormal, it may indicate that the granary has problems such as poor ventilation or equipment failure, and managers can check and deal with them in advance.
Data analysis and reporting
The data analysis function provided by the cloud platform is one of the core links of data management.
There are many methods for data analysis, such as correlation analysis, which can study the relationship between different environmental parameters such as temperature, humidity, and oxygen content. Through this analysis, managers can understand which parameters are closely related, so as to better grasp the inherent laws of the granary environment.
At the same time, based on the results of data analysis, the system can generate a detailed report. This report is like a “physical examination report” of the granary environment, which lists in detail the statistical data, changing trends, abnormal conditions and related analysis conclusions of each environmental parameter. Managers can optimize granary management strategies and improve management efficiency based on this report.
User management
Multi-user management
In the actual operation of granary management, it often involves the participation of multiple departments and personnel at different levels. The system supports multiple management accounts and can be managed in groups. This function meets the complex personnel organizational structure requirements in granary management.
Different departments and personnel have different responsibilities in grain silo management. For example, the staff of the storage department may be mainly responsible for daily inspections and equipment maintenance, while the staff of the quality control department pays more attention to the quality of grain. Through group management, management personnel can be divided into different groups according to different functions, such as equipment management group, environmental monitoring group, grain quality inspection group, etc.
In addition, different permissions can be granted to different groups. Members of the equipment management group have the authority to operate and maintain the equipment in the silo, such as starting or stopping the air conditioner, etc.; members of the environmental monitoring group have more authority to view environmental parameters and video surveillance images; members of the grain quality inspection group can view data and reports related to grain quality. This division of permissions ensures that each person can only operate within the scope of his or her responsibilities, which not only improves work efficiency but also ensures the security of the system.
By realizing multi-person collaborative management of the silo, the professional advantages of various departments and personnel can be fully utilized, the workload of manual operation and inspection can be reduced, and work efficiency can be improved. For example, when conducting large-scale grain silo inventory or environmental inspection, members of different groups can perform their respective tasks at the same time without duplication of work, which greatly improves the efficiency of the entire grain silo management.
Cost-effectiveness
Reduce management costs
Traditional grain silo management methods require a lot of investment in manpower, material resources and time. A large number of staff need to be arranged for regular inspections, and the accuracy and timeliness of manual inspections are difficult to guarantee, which may lead to some problems not being discovered in time, resulting in greater losses.
The application of Io T technology has changed this situation. Through automated real-time monitoring and intelligent regulation, the dependence on manual inspections has been greatly reduced. Sensors can monitor the granary environment 24 hours a day, and the equipment linkage function can automatically adjust according to environmental changes without frequent manual intervention. In this way, the expenditure of labor costs can be reduced, and the risks caused by manual operation errors can also be reduced.
In terms of equipment maintenance, the Io T system can monitor the operating status of the equipment in real time, predict possible equipment failures in advance, and perform preventive maintenance. Compared with the traditional method of repairing equipment after failure, this can reduce equipment maintenance costs and extend the service life of the equipment. Through the Internet of Things technology, the cost of grain storage management and operation can be significantly reduced, and the accuracy and efficiency of management can be improved.
Improve grain quality
The quality of grain is directly related to the safety and economic value of grain. In the granary environment, any slight environmental change may affect the quality of grain.
The real-time monitoring and intelligent control functions of the Internet of Things technology ensure that the granary environment meets safety standards. For example, if the temperature and humidity are always kept within the range suitable for grain storage, the grain can be effectively prevented from mildewing. Mildew is one of the common problems in the grain storage process. Once the grain is mildewed, it will not only cause the loss of grain, but also may contaminate other healthy grains.
In addition, by accurately controlling environmental parameters such as oxygen content, the growth and reproduction of pests can be inhibited. Pest infestation is also an important factor affecting grain quality. They will eat grain and reduce the quality of grain. Through the effective control of the granary environment by the Internet of Things technology, the storage quality of grain is improved and the safety of grain is guaranteed.
In modern society, the application of Internet of Things technology in granary environmental monitoring has far-reaching significance. It not only improves the quality and safety of grain storage, but also greatly reduces management and operation costs and improves management efficiency. From the perspective of food security, through real-time monitoring, intelligent control, data management and multi-user collaboration, Io T technology has become a powerful assistant for granary environmental monitoring, providing a solid guarantee for food security.
Against the background of growing global food demand, it is crucial to ensure the quality and safety of food during storage. The application of Io T technology effectively solves many drawbacks in traditional granary management methods, making granary management more scientific and intelligent. Io T technology has brought a new model to granary environmental monitoring and is a well-deserved guardian of wisdom.
