Description

Technical Field

[0001] The present invention relates to the technical field of oxygen monitoring, and specifically to a real-time monitoring system for the safe oxygen concentration during the storage and transportation of grain in granaries. Background Art

[0002] A granary is an essential building for storing grains. Especially with the continuous increase in China's grain production, granaries have been built in various places in China for grain storage. During the process of storing grains in a granary, it is usually carried out in a closed environment. In order to prevent grain spoilage, it is necessary to monitor the temperature, humidity, CO2 concentration, oxygen concentration, nitrogen concentration, air pressure, etc. in the granary, so as to facilitate the management personnel to adjust the working conditions in the granary in a timely manner to ensure the long-term storage of grains. In addition, during the continuous external supply of grains, the amount of grains in the granary is continuously decreasing, and the management personnel need to timely understand the change of the grain quantity in the granary and replenish the grains in the granary in a timely manner.

[0003] China has a huge grain reserve scale, and the most important work during storage is to prevent pests and molds. Because the growth and metabolic activities of pests and molds not only consume the quantity of grains, cause the deterioration of grain quality, but also may lead to serious food safety problems. Aflatoxin, which has strong toxicity and carcinogenicity, is produced by the growth and metabolism of molds such as Aspergillus flavus in grains. Therefore, only by predicting and warning the activities of pests and molds at an early stage and taking effective control measures in a timely manner can the deterioration of grain quality and the occurrence of toxin contamination be prevented.

[0004] During the storage of grains in a granary, the gases in the granary will have a great impact on the storage of grains. Therefore, real-time monitoring of the oxygen index in the granary is of great significance for ensuring the quality and safety of stored grains in the granary. The existing granary gas monitoring systems have a single function and poor effect, and cannot provide technical support and scientific basis for scientific grain storage.

[0005] In view of the above technical defects, a solution for a real-time monitoring system for the safe oxygen concentration during the storage and transportation of grain in granaries is now proposed. Summary of the Invention

[0006] To solve the above problems, the present invention provides the following technical solutions:

[0007] A warehouse for storing grains and installing and fixing each component.

[0008] An oxygen concentration monitoring component disposed in the warehouse for real-time monitoring of the oxygen concentration during the storage and transportation of the granary.

[0009] A display component disposed outside the warehouse, connected to the oxygen concentration monitoring component and feeding back the monitoring data of the warehouse.

[0010] A control system, which is connected to the oxygen concentration monitoring component and the display component, and is used for real-time monitoring and visual analysis of the oxygen concentration during the storage and transportation of grain in the granary.

[0011] Furthermore, the oxygen concentration monitoring component includes a first group of oxygen concentration monitoring sensors and a second group of oxygen concentration monitoring sensors. The first group of oxygen sensors and the second group of oxygen sensors are arranged oppositely and along the warehouse wall. The first group of oxygen sensors and the second group of oxygen sensors are used for real-time monitoring of the oxygen concentration on both sides of the warehouse.

[0012] Furthermore, the display component includes a control cabinet and an LCD display screen. The control cabinet is electrically connected to the first group of oxygen concentration sensors and the second group of oxygen concentration sensors. The LCD display screen is arranged on the control cabinet and is used for feedback and visual analysis of the monitoring data of the first group of oxygen concentration sensors and the second group of oxygen concentration sensors.

[0021] Furthermore, the real-time monitoring includes that the system continuously monitors the oxygen concentration inside the granary, instantaneously updates the data when there are changes, uses highly sensitive oxygen sensors to ensure accurate detection of tiny changes in oxygen concentration. When the oxygen concentration reaches or exceeds the set safety threshold, the system immediately triggers an alarm, feeds back to the management personnel or the automatic control system to ensure a quick response, visually displays the real-time monitoring data on the monitoring screen for the management personnel to view at any time. Combining network technology, the management personnel can remotely access the monitoring system through devices such as mobile phones and computers to view the real-time data at any time without being restricted by location. Multiple thresholds and rules are set. When abnormal situations are detected, such as a sudden drop or rise in oxygen concentration, the system can automatically identify and issue a warning to prevent potential risks.

[0022] Furthermore, the alarm system includes alerting relevant personnel through sound alarms, visual alarms, text messages, emails or mobile application notifications. According to different situations of oxygen concentration, the system sets multiple alarm levels.

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] As Figures 1 - 4 shown, the real-time monitoring system for the safe oxygen concentration during the storage and transportation of grain includes:

[0051] Warehouse 1, which is used to store grain and install and fix each component;

[0052] Oxygen concentration monitoring component 2, which is arranged in warehouse 1 and is used to monitor the oxygen concentration during the storage and transportation of grain in real time;

[0054] Control system, which is connected to oxygen concentration monitoring component 2 and display component 3, and the control system is used to monitor the oxygen concentration during the storage and transportation of grain in real time and perform visual analysis.

[0055] Specifically, the monitoring system of the present invention is applicable to operations in confined space environments. Due to the high-frequency inspection requirements (large number of warehouses) in grain warehouses, this system enables users to conveniently and intuitively understand the situation inside the warehouse from a distance and facilitates the approval for confined space operations. Here, a confined space refers to a space that is enclosed or partially enclosed, relatively isolated from the outside world, has narrow entrances and exits, poor natural ventilation, and is prone to the accumulation of toxic, harmful, flammable, and explosive substances or insufficient oxygen content. Equipment and facilities such as storage tanks and granaries in grain warehouses all belong to confined spaces, and their main risks include poisoning and asphyxiation, explosion risks, and mechanical injuries and collapses. Therefore, when entering a grain warehouse in a confined space, the following prior preparations are required, including approval systems, education and training, ventilation detection, and personal protection. Similarly, during the operation process, the following management is also required: full-process monitoring, emergency preparation, safe operation, etc. At the end, two steps need to be taken: counting personnel and tools and closing the warehouse door and recycling equipment.

[0056] Specifically, the oxygen concentration monitoring component 2 includes a first group of oxygen concentration monitoring sensors and a second group of oxygen concentration monitoring sensors. The first group of oxygen sensors 21 and the second group of oxygen sensors 22 are arranged oppositely and are installed along the warehouse wall of the warehouse 1 and above the grain. The first group of oxygen sensors 21 and the second group of oxygen sensors 22 are used to monitor the oxygen concentration on both sides of the warehouse 1 in real time. The display component 3 includes a control cabinet 31 and an LCD display screen 32. The control cabinet 31 is set outside the warehouse door of the warehouse 1. The control cabinet 31 is electrically connected to the first group of oxygen sensors 21 and the second group of oxygen sensors 22. The LCD display screen 32 is set on the control cabinet 31. The LCD display screen 32 is used to feedback the monitoring data of the first group of oxygen sensors 21 and the second group of oxygen sensors 22 and perform visual analysis, facilitating the warehouse keeper to view and understand the oxygen concentration situation inside the warehouse 1. Moreover, the LCD display screen uses red, green, and yellow three-color lights for display, where the red light is on indicating a high oxygen concentration, the green light is on indicating a normal oxygen concentration, and the yellow light is on indicating a low oxygen concentration.

[0057] The monitoring system includes:

[0058] Real-time monitoring, including equipping with high-precision oxygen sensors to monitor the oxygen concentration in the granary in real time to ensure it is within a safe range;

[0059] Alarm system, when the oxygen concentration exceeds the preset safety threshold, the system will automatically issue an alarm to remind relevant personnel to take measures to prevent safety hazards such as grain mildew or fire;

The system can be configured and adjusted according to the actual needs of different granaries to meet various storage conditions and management requirements. It supports integration with existing management systems to facilitate system upgrades and expansions. It can effectively improve the intelligent level of granary management, ensure the safety and stability of the grain storage environment, and provide strong technical support for food security.

[0065] Specifically, the real-time monitoring includes that the system will continuously monitor the oxygen concentration inside the granary and update the data immediately when changes occur. It uses a highly sensitive oxygen sensor to ensure that it can accurately detect small changes in oxygen concentration. When the oxygen concentration reaches or exceeds the set safety threshold, the system will immediately trigger an alarm and feedback to the management personnel or automatic control system to ensure a quick response. The real-time monitoring data is intuitively displayed on the monitoring screen, which is convenient for management personnel to view at any time. Combined with network technology, management personnel can remotely access the monitoring system through mobile phones, computers and other devices to view real-time data at any time without location restrictions. Multiple thresholds and rules are set. When an abnormal situation is detected, such as a sudden drop or rise in oxygen concentration, the system can automatically identify and issue an early warning to prevent potential risks. The application of real-time monitoring in granary management not only improves the safety of granaries, but also effectively prevents and reduces food losses caused by environmental factors.

[0066] Specifically, the alarm system includes methods such as sound alarm, visual alarm, SMS, email, or mobile app notifications to alert relevant personnel. According to different oxygen concentration situations, the system sets multiple alarm levels. When the monitored oxygen concentration exceeds the safety threshold, the system will immediately trigger an alarm to ensure that relevant personnel are notified in a timely manner or automatically trigger the linkage device alarm. The system records the time, type, and handling situation information of each alarm event, facilitating post-event analysis and improvement of management measures. The monitoring system is linked with the ventilation and exhaust equipment in the granary. When abnormal oxygen concentration is detected, these devices are automatically activated for adjustment to ensure that the environment returns to a safe state. In addition to sounding an alarm on-site, the system also supports remote alarm, ensuring that even when the management personnel are not on-site, they can be informed and handle abnormal situations in a timely manner. The alarm system plays a crucial role in the safety management of granary warehousing and outbound operations, being able to prevent and respond to potential safety hazards in a timely manner, and ensuring the safety and stability of the grain storage environment.

[0067] Specifically, the data recording and analysis include recording the oxygen concentration data in the granary to ensure that detailed records of environmental parameters are available at all times. The recorded data will be stored in the system database for convenient subsequent query and analysis. These data can be stored in different time periods such as daily, weekly, and monthly, recording temperature, humidity, and other environmental parameters, providing data support for comprehensive environmental monitoring. Data is automatically backed up regularly to prevent data loss and ensure data integrity and security. Through the analysis of historical data, the system generates a trend chart of oxygen concentration changes to help management personnel understand long-term changes, discover potential problems, analyze abnormal changes in the data, identify abnormal oxygen concentration fluctuations, provide early warning information, and automatically generate daily, weekly, monthly, and annual reports, providing detailed oxygen concentration data statistics and analysis results, supporting exports in multiple formats such as PDF and Excel. By comparing data from different time periods or different granaries, the system helps management personnel find differences, analyze reasons, and optimize management measures. Using historical data and advanced analysis algorithms, the system predicts future oxygen concentration changes and takes preventive measures in advance. Through data analysis, abnormal oxygen concentration is detected and processed in a timely manner to ensure granary safety. The analysis report and trend prediction provide a scientific basis for management decision-making, helping to optimize the granary management strategy. Through the monitoring and analysis of environmental parameters, the quality of grain storage is ensured, and mildew and losses are reduced. The recording and analysis of data can be used as the basis for compliance review and third-party audits, proving the standardization and effectiveness of granary management. The data recording and analysis function improves the intelligent level of granary management through the scientific management and in-depth analysis of a large amount of data, contributing to achieving refined and scientific management and ensuring the safety and stability of the grain storage environment.
