Description

Technical Field

[0001] The present application relates to the field of grain storage, and in particular to a bulk grain storage method, control system, storage medium and program product. Background Art

[0002] With the development of social economy, the issue of grain storage has received more and more attention. Reasonable grain storage can effectively ensure grain quality, reduce storage losses, and ensure food safety. However, different types of grains have different storage requirements. If the optimal storage conditions cannot be met, it will lead to problems such as deterioration of grain quality and mildew.

[0003] At present, grain storage systems usually can only adopt a single storage method, which is difficult to accommodate the storage needs of multiple conditions such as packaged and bulk grain. For example, when storing packaged grain, the grain needs to be processed to meet the standards, packed into special moisture-proof packaging bags, and then stored in a granary with good sealing performance; when storing bulk grain, it is necessary to select a granary with complete ventilation and grain cooling systems, prevent pests during storage, ventilate regularly, and monitor grain temperature, moisture and other data.

[0004] However, as the scale of storage increases, the existing single storage system may not be able to meet the storage requirements of multiple conditions of packaged and bulk food. There are problems such as low storage efficiency and poor adaptability, making it difficult to achieve more intelligent and differentiated storage management and ensure food storage safety. Summary of the invention

[0005] The present application provides a packaged and bulk grain storage method, control system, storage medium and program product, which are used to store both packaged grain and bulk grain in the same granary, saving resources, improving storage efficiency, and reducing grain loss, thereby realizing more intelligent and differentiated storage management and ensuring grain storage safety.

[0006] In a first aspect, the present application provides a method for regulating the storage environment of bulk grain, which is applied to a control system, the method comprising: obtaining storage information of a storage area; when the storage information shows that packaged grain is placed in the storage area, determining the optimal storage conditions according to the type of packaged grain and a preset grain type-storage condition correspondence table; if the current packaged grain storage environment data of the storage area does not meet the optimal storage conditions, sending a packaged grain storage environment adjustment instruction to an environmental control device, the current packaged grain storage environment data including the current packaged grain storage temperature and the current packaged grain storage humidity, and the packaged grain storage environment adjustment instruction including environmental adjustment parameters; when the storage information shows that bulk grain is placed in the storage area, determining whether the current bulk grain storage environment data of the storage area meets the preset bulk grain storage conditions; if not, sending a bulk grain storage environment adjustment instruction to the environmental control device, the bulk grain storage environment adjustment instruction including an environmental operation mode.

[0007] By adopting the above technical solution, first, the control system obtains the storage information of the storage area, accurately distinguishes packaged grains, bulk grains and varieties, and then the control system determines whether the current environmental data of the storage area meets the storage requirements of packaged grains or bulk grains. If not, the control system adjusts the current environmental data of the storage area according to the most suitable storage conditions for packaged grains or bulk grains, so that packaged grains or bulk grains can be stored in a suitable environment. Whether it is well-packaged grains, such as bags of rice and flour, or bulk grains, such as wheat, rice, corn, soybeans, etc., they can get a suitable storage environment in this granary, thereby ensuring that all forms of grain can be stored under the best conditions, effectively preventing the quality of grains from deteriorating, deteriorating and damaging due to improper storage environment, and greatly improving the overall efficiency and quality of grain storage. For example, for packaged rice, the humidity can be accurately controlled to avoid moisture; for bulk wheat grains, the temperature can be reasonably adjusted to prevent insects or mildew. In short, this method successfully breaks the boundary between packaged grain and bulk grain storage. Both packaged grain and bulk grain can be stored in the same granary, saving resources, improving storage efficiency, and reducing grain losses, thereby realizing more intelligent and differentiated storage management.

[0008] In combination with some embodiments of the first aspect, in some embodiments, if the current packaged grain storage environment data of the storage area does not meet the optimal storage conditions, a packaged grain storage environment adjustment instruction is sent to the environmental control device, and the current packaged grain storage environment data includes the current packaged grain storage temperature and the current packaged grain storage humidity. The packaged grain storage environment adjustment instruction includes environmental adjustment parameters, specifically including: when the current packaged grain storage environment data of the storage area does not meet the optimal storage conditions, obtaining the humidity difference between the current packaged grain storage humidity and the optimal storage humidity, and the temperature difference between the current packaged grain storage temperature and the optimal storage temperature; determining the environmental adjustment parameters based on the humidity difference and the temperature difference; and sending the packaged grain storage environment adjustment instruction containing the environmental adjustment parameters to the environmental control device.

[0009] By adopting the above technical solution, the storage environment of packaged grain can be precisely regulated by accurately calculating the humidity difference between the current storage humidity of packaged grain and the optimal storage humidity, and the temperature difference between the current storage temperature of packaged grain and the optimal storage temperature. This method does not simply judge whether the environment is suitable, but quantifies the specific parameters that need to be adjusted, making environmental regulation more accurate and efficient. By sending packaged grain storage environment adjustment instructions containing specific environmental adjustment parameters, the environmental regulation equipment can make targeted adjustments according to actual needs, avoiding the problem of over-regulation or under-regulation. This refined regulation can not only create the best storage environment for packaged grain, but also reduce energy consumption and improve equipment efficiency, thereby maximizing economic benefits while ensuring food quality.

[0010] In combination with some embodiments of the first aspect, in some embodiments, if the conditions are not met, a bulk grain storage environment adjustment instruction is sent to the environmental control device, and the bulk grain storage environment adjustment instruction includes an environmental operation mode, specifically including: searching for an environmental control device control strategy that matches the current bulk grain storage environment data according to the equipment adjustment table; determining the environmental operation mode according to the environmental control device control strategy; and sending the bulk grain storage environment adjustment instruction including the environmental operation mode to the environmental control device.

[0011] By adopting the above technical solution, the intelligent control of the bulk grain storage environment is realized. By relying on the control strategy of the environmental control equipment that matches the current bulk grain storage environment data, the control system can quickly determine the most suitable environmental operation mode, rather than adopting a fixed control method. This data-driven dynamic control method can flexibly select the optimal control strategy according to different bulk grain storage requirements and actual environmental conditions, which not only improves the scientificity and effectiveness of bulk grain storage, but also optimizes equipment operation according to actual conditions, improves energy utilization efficiency, and reduces operating costs. In combination with some embodiments of the first aspect, in some embodiments, after the step of determining the environmental operation mode according to the environmental control equipment control strategy, the method also includes: based on a preset equipment-valve-opening correspondence table, according to the environmental operation mode, determining multiple valves associated with each environmental control equipment, and the opening of the multiple valves; according to the opening of the multiple valves, determining the open and closed states of the multiple valves.

[0012] By adopting the above technical solution and introducing the equipment-valve-opening correspondence table, refined management from macro-environment operation mode to micro-equipment control is achieved. By determining multiple valves associated with each environmental control device and the opening of multiple valves, the control system can accurately control the operating status of each environmental control device. This multi-level linkage control method makes environmental control more flexible and precise. By adjusting the opening and closing status of multiple valves, complex environmental control needs can be achieved, such as simultaneous adjustment of temperature, humidity, ventilation, etc. This refined control can not only better meet the storage needs of different types of bulk grains, but also optimize resource allocation, improve equipment utilization efficiency, achieve energy savings and cost control, thereby improving the economic benefits of storage while ensuring grain quality.

[0013] In combination with some embodiments of the first aspect, in some embodiments, if the conditions are not met, a bulk grain storage environment adjustment instruction is sent to the environmental control device, and the bulk grain storage environment adjustment instruction includes a step of an environmental operation mode. The method also includes: after the environmental control device has been working for a preset period of time, obtaining current environmental data of the storage area; when the current environmental data does not meet the preset bulk grain storage conditions, based on the equipment operating time extension rule table, extending the working time of the environmental control device; when the current environmental data reaches the preset bulk grain storage conditions, based on the equipment adjustment table, adjusting the environmental control device to the default mode.

[0014] By adopting the above technical solution, a feedback mechanism and adaptive adjustment strategy for environmental control are introduced. By detecting the current environmental data of the storage area again after the environmental control equipment has worked for a preset period of time, the control system can evaluate the current control effect. If the current environmental data does not meet the preset bulk grain storage conditions, the control system will extend the working time of the environmental control equipment according to the equipment operation time extension rule table. This mechanism ensures the continuity and effectiveness of environmental control. If the current environmental data reaches the preset bulk grain storage conditions, the control system will automatically adjust the environmental control equipment to the default mode to avoid energy waste caused by excessive adjustment. This intelligent adjustment strategy not only improves the accuracy of environmental control, but also can dynamically adjust the operating parameters according to actual conditions to meet the needs of different grain varieties and different storage stages. At the same time, this method is also conducive to extending the life of equipment, reducing maintenance costs, and improving the economic benefits of the entire control system.

[0015] In combination with some embodiments of the first aspect, in some embodiments, the method also includes: during the operation of the environmental control equipment, periodically recording environmental data and equipment operating parameters to obtain an environmental control log; based on the environmental control log, adjusting the equipment adjustment table to improve the operating efficiency of the environmental control equipment.

[0016] By adopting the above technical solution, a self-learning intelligent control and optimization mechanism for environmental control is introduced. By periodically recording environmental data and equipment operating parameters, the control system can accumulate a large amount of actual operating data and form a detailed environmental control log. The environmental control log can not only be used for the analysis and fault diagnosis of the control system's operating status, but also provides an important basis for further optimizing the control strategy. The control system can dynamically adjust the equipment adjustment parameters so that the environmental control strategy can continuously adapt to the actual situation and improve the accuracy and efficiency of the control. This self-optimization mechanism enables the control system to become more and more intelligent as the use time increases. It can not only better adapt to the storage needs of different types of grains, but also automatically adjust the control parameters according to seasonal changes and regional differences, greatly improving the adaptability and practicality of the control system.

[0017] In combination with some embodiments of the first aspect, in some embodiments, during the operation of the environmental control equipment, environmental data and equipment operating parameters are periodically recorded. After the step of obtaining the environmental control log, the method also includes: if the equipment operating parameters of the environmental control equipment do not meet the standard equipment operating parameters, sending equipment maintenance information to the user.

[0018] By adopting the above technical solution, when the control system finds that the equipment operating parameters of the environmental control equipment do not meet the standard equipment operating parameters, it will send maintenance information to the user in a timely manner. This active early warning mechanism can effectively prevent equipment failures and avoid abnormal grain storage environment caused by equipment problems. It can not only ensure the continuous and efficient operation of environmental control equipment, but also reduce the risks and losses caused by sudden failures. At the same time, this method also provides data support for the preventive maintenance of equipment, which helps to formulate a more scientific equipment maintenance plan, extend the service life of equipment, and reduce long-term operating costs.

[0019] In a second aspect, an embodiment of the present application provides a control system, comprising: one or more processors and a memory; the memory is coupled to the one or more processors, the memory is used to store computer program code, the computer program code includes computer instructions, and the one or more processors call the computer instructions to enable the control system to execute the method described in the first aspect and any possible implementation method of the first aspect.

[0020] In a third aspect, an embodiment of the present application provides a computer program product comprising instructions, which, when the computer program product is run on a control system, enables the control system to execute the method described in the first aspect and any possible implementation of the first aspect.

[0021] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, comprising instructions, which, when executed on a control system, enable the control system to execute the method described in the first aspect and any possible implementation of the first aspect.

[0022] It is understandable that the control system provided in the second aspect, the computer program product provided in the third aspect, and the computer storage medium provided in the fourth aspect are all used to execute the method provided in the embodiment of the present application. Therefore, the beneficial effects that can be achieved can refer to the beneficial effects in the corresponding method, which will not be repeated here.

[0023] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: 1. Due to the combination of storage information identification and environmental data monitoring, it is possible to accurately distinguish packaged grain from bulk grain, and perform differentiated management according to the storage requirements of different types of grain, effectively solving the problem that a single storage method in the existing technology is difficult to be compatible with mixed storage requirements, and thus realizing the intelligent management of both packaged grain and bulk grain in the same granary. This method not only improves the utilization efficiency of granaries and reduces the construction cost of special storage facilities, but also can flexibly adjust the storage environment according to the characteristics of different grains, maximize the quality of grain, and reduce storage losses. Especially for grain depots that need to frequently switch storage varieties, this method can greatly improve operational flexibility and economic benefits.

[0024] 2. Due to the adoption of a dynamic optimization mechanism based on the equipment adjustment table and the environmental control log, the environmental control strategy can be continuously improved, the equipment operation efficiency can be improved, and the problem of the fixed mode operation of the environmental control equipment in the existing technology and the difficulty in adapting to the complex and changing environment can be effectively solved, thereby realizing the adaptive optimization of grain storage environmental control. This method can timely discover and correct unreasonable environmental control strategies by continuously recording and analyzing environmental data and equipment operating parameters, avoiding energy waste and storage quality degradation caused by excessive or insufficient control. At the same time, through the long-term accumulation of data and experience, the control system can gradually form a more accurate and efficient environmental control strategy, and continuously improve the scientific and refined level of grain storage.

[0025] 3. Due to the combination of multi-level control and automated maintenance, the storage environment can be precisely controlled and the equipment can be maintained in a timely manner, which effectively solves the problem that it is difficult for manual management to timely discover and deal with environmental anomalies and equipment failures in the existing technology, thereby realizing intelligent supervision of the entire grain storage process. This method can flexibly adjust the storage environment according to actual conditions by setting up a multi-level control mechanism, such as environmental adjustment parameters, equipment operation mode, valve opening, etc.; at the same time, by automatically comparing equipment operation parameters with standard equipment operation parameters, potential faults can be discovered in a timely manner and maintenance information can be pushed, greatly improving equipment management efficiency and reliability. This not only reduces labor costs, but more importantly, it guarantees the safety and stability of grain storage to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to any or all possible combinations comprising one or more of the listed items.

[0028] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0029] For ease of understanding, the application scenarios of the embodiments of the present application are introduced below.

[0030] A provincial grain reserve center is responsible for managing dozens of large granaries across the province. However, with the diversification of grain types and changes in storage needs, the provincial grain reserve center faces severe challenges. Sometimes it needs to store large quantities of bulk wheat, and sometimes it needs to store bagged rice. The traditional single storage method can no longer meet this multi-condition demand. For example, the bulk corn that was just unloaded last month has not been transferred in time, and a large number of packaged rice will be received next month. If dedicated storage facilities are established for each type of grain, it will not only be costly, but also cause a large amount of storage space to be idle when storage needs change. At the same time, different grains have different requirements for temperature and humidity. How to accurately control the storage environment so that both packaged grain and bulk grain can be stored in the same granary has become an urgent problem to be solved. The managers of the provincial grain reserve center urgently need an intelligent solution that can flexibly respond to multiple grain storage needs while ensuring storage quality.

[0031] In the relevant technology, the grain storage system can usually only adopt a single storage method, which is difficult to be compatible with multiple storage conditions. For example, when storing packaged grain, the grain needs to be processed to meet the standards, packed into special moisture-proof packaging bags, and then stored in a granary with good sealing performance; when storing bulk grain, it is necessary to select a granary with complete ventilation, grain cooling and other systems, and prevent pests during storage, ventilate regularly, and monitor grain temperature, moisture and other data. Obviously, when the storage types include both packaged grain and bulk grain, it is difficult for the existing technology to meet the storage requirements of multiple conditions.

[0032] With the present application, when a batch of bulk wheat arrives, the control system immediately identifies that it is bulk grain by receiving the storage information of the storage area and sends it to the control system. The control system then queries the preset bulk grain storage conditions and finds that the current temperature in the granary is too high. The control system immediately sends instructions to the environmental control equipment and starts the cooling mode. When a batch of packaged rice arrives, the control system identifies that it is packaged grain by receiving the storage information of the storage area and sends it to the control system. The control system then determines the optimal storage conditions based on the type of rice. If the humidity in the current granary rises slightly but has not yet reached the level that requires intervention, the existing environmental settings are temporarily maintained. By precisely controlling the storage environment when each type of grain is stored, not only is it ensured that different types of grain are in the best storage state, but it also greatly reduces manpower input and energy consumption.

[0033] Here is a dual-purpose warehouse for storing both packaged grain and bulk grain. The dual-purpose warehouse includes wall insulation, transverse ventilation and a grain cooling air handling unit.

[0034] 1. Wall insulation The exterior wall is made of 490mm thick brick wall + 100mm thick extruded insulation board + 120mm thick brick wall. Since the insulation layer is located between the inner and outer walls, in order to prevent the wall from absorbing moisture and causing moisture to increase and affect the insulation performance and service life, a waterproof and breathable membrane is set on the inner side of the outer wall, and a 20mm thick 1:2.5 cement mortar is set on the inner side of the inner wall for painting, mixed with 3% silicon densifier (secondary survival), and a waterproof and air-proof glue is brushed in the vertical and horizontal directions to prevent the internal moisture from affecting the insulation layer. The roof adopts an arched roof, and the upper chord of the arched plate adopts a 60mm thick extruded polystyrene board insulation layer. The upper side of the lower chord of the arched plate adopts a 50mm thick rock wool with aluminum foil to be fully spread and glued. An air body is formed between the upper and lower chords, and the heat from the roof is discharged through the ventilation shutters on both sides of the granary and the roof fan. The ground adopts a 100mm thick extruded polystyrene board insulation layer to effectively prevent the conduction loss of (quasi) low-temperature grain storage cold air in the warehouse to the ground. Effective insulation and energy-saving measures are adopted for the walls, roof and floor of the dual-purpose warehouse for bag and bulk. According to the comparison of summer grain storage data records, when the unit cooling is not adopted, the temperature of the dual-purpose warehouse for bag and bulk is 2-3 degrees lower than that of the ordinary standard warehouse.

[0035] (ii) Horizontal ventilation Ventilation ducts are installed on the inner wall of the dual-purpose warehouse for packing and bulking to ventilate the entire warehouse grain pile horizontally. Compared with the vertical ventilation system of the ground cage and the ground trough in the warehouse, the number of ventilation ducts is small, the ventilation path ratio is small, the ventilation uniformity is good, there is almost no ventilation dead corner, the ventilation efficiency is high, and the energy consumption is low. It also avoids the installation or removal of the ground cage ventilation duct for grain in and out in the prior art. There is no ventilation duct of any form on the floor of the dual-purpose warehouse for packing and bulking, and the floor is complete, which is conducive to mechanized grain in and out operations, reducing the labor intensity of employees in grain in and out, and saving grain in and out time.

[0036] (III) Grain cooling air handling unit The bulk bin is equipped with a transverse ventilation system, and the upper interlayer of the slow cooling room is equipped with a grain cooling air handling unit. Each transverse ventilation main air duct is connected to the air handling unit. Figure 1 As shown, K-1A and K-1B serve the warehouses of axes 1 to 10, and K-2A and K-2B serve the warehouses of axes 13 to 22. Taking the warehouses of axes 1 to 10 as an example, the operating conditions are as follows: 1. Cooling ventilation mode: When the temperature in the warehouse minus the outdoor air temperature ≥ 3°C, turn off the K-1B unit and its valve, turn off VM-1A, turn on VH-1A, VP-1A, VX-1A, VS-1A, and turn on the return fan of the K-1A unit. Outdoor air → VX-1A → VS-1A → horizontal main and secondary branch air ducts on the B-axis side → grain pile → horizontal main and secondary branch air ducts on the A-axis side → K-1A unit return fan → VP-1A → discharged to the outside.

[0037] 2. Grain cooling mode: After the cooling and ventilation mode ends, if the storage temperature has not been reached, operate the grain cooling mode. Turn off the K-1B unit and its valve, turn off VX-1A, put valves VM-1A and VP-1A in the adjustment position, turn on VH-1A, VS-1A, turn on the return fan and compressor of the K-1A unit, and let the air leak into the grain pile and the negative pressure → the horizontal primary and secondary branch air ducts on the A-axis side → K-1A unit cooling → the horizontal primary and secondary branch air ducts on the B-axis side → grain pile. The K-1A and K-1B units work in rotation to balance the temperature in the warehouse. The operating mode of the packaged and bulk dual-purpose warehouse system is the same, and the unit operating conditions are slightly different. In the packaging warehouse mode, the system resistance decreases and the system air volume increases.

[0038] 3. Heating of the slow and cold room: K-1 and K-2 air conditioning units are respectively provided with waste heat utilization function sections for heating of the slow and cold room. The outdoor air is heated by the waste heat utilization function section and then sent to the slow and cold room. The cooled air seeps out from the door gap of the slow and cold room. A double-layer louver air supply outlet is set on the upper side of the slow and cold room, with air supplied from the top of the side and discharged under positive pressure from the lower part of the door.

[0039] For specific roof ventilation and air conditioning plan, ventilation and air conditioning plan above the grain stacking line, and cooling air conditioning unit functional section diagram, please refer to Figure 2 , Figure 3 , Figure 4 .

[0040] The following is a description of the process of the method provided by this implementation. Figure 5 , is a schematic flow chart of a bulk grain storage method in an embodiment of the present application.

[0041] S501, obtaining storage information of a storage area; The control system refers to the central processing unit that manages and regulates the storage area environment and is used to perform various monitoring and adjustment functions; the storage area refers to a specific space used to store grain, such as a granary or warehouse; storage information refers to data about the storage status of grain in the storage area, including grain type, grain quantity, storage time, etc.

[0042] When the control system starts to execute the packaged and bulk grain storage management task, it first executes step S501. Specifically, the control system automatically obtains the storage information of the storage area by connecting to various data acquisition devices in the storage area, such as radio frequency identification (RFID) readers, weight sensors, image recognition systems, etc. Such storage information may include the type of grain currently stored (such as wheat, corn, etc.), storage form (packaged or bulk), storage quantity, storage time, etc. The control system can also obtain the storage information of the storage area by manual input, which is not limited here.

[0043] S502, when the storage information shows that packaged grain is placed in the storage area, determining the optimal storage condition according to the type of packaged grain and a preset grain type-storage condition correspondence table; Packaged grain refers to grain that has been specially packaged, such as rice and flour packed in woven bags or plastic bags. The grain type-storage condition correspondence table refers to a pre-set data table used to indicate the optimal storage conditions for different types of packaged grains. The optimal storage conditions refer to the environmental parameters that can keep the packaged grains in the best quality, and the environmental parameters usually include temperature, humidity, etc.

[0044] When the control system determines that the storage area stores packaged grain, it needs to determine the optimal storage conditions for the packaged grain. Specifically, the control system first identifies the type of packaged grain, such as rice, flour, etc. Then, the control system queries the preset grain type-storage condition correspondence table to find the optimal storage conditions for the type of packaged grain. In this way, the control system can quickly determine the most suitable storage environment for different types of packaged grains and provide accurate target parameters for subsequent environmental control.

[0045] S503, if the current packaged grain storage environment data of the storage area does not meet the optimal storage conditions, sending a packaged grain storage environment adjustment instruction to the environment control device, the current packaged grain storage environment data includes the current packaged grain storage temperature and the current packaged grain storage humidity, and the packaged grain storage environment adjustment instruction includes an environment adjustment parameter; Among them, the current packaged grain storage environment data represents the real-time environmental parameters of the storage area, mainly including temperature and humidity. Environmental control equipment refers to equipment that can adjust the storage environment, such as air conditioners, dehumidifiers, etc. Packaged grain storage environment adjustment instructions refer to control commands sent by the control system to the environmental control equipment. Environmental adjustment parameters are used to indicate the specific environmental indicators that need to be adjusted and the adjustment range.

[0046] After determining the optimal storage conditions, the control system needs to evaluate whether the current storage environment meets the requirements and make adjustments if necessary. Specifically, the control system first obtains the current packaged grain storage environment data of the storage area, mainly including the current temperature and humidity. Then, the control system compares the current packaged grain storage environment data of the storage area with the previously determined optimal storage conditions. If it is found that the current packaged grain storage environment data of the storage area does not meet the optimal storage conditions, such as the temperature is too high or the humidity is too low, the control system will generate a packaged grain storage environment adjustment instruction. This packaged grain storage environment adjustment instruction contains specific environmental adjustment parameters, such as the temperature value that needs to be lowered or the humidity value that needs to be increased. Finally, the control system sends this packaged grain storage environment adjustment instruction to the corresponding environmental control equipment, such as air conditioners or humidifiers, to achieve precise control of the storage environment and ensure that the packaged grain is in the best storage state.

[0047] S504, when the storage information shows that bulk grain is placed in the storage area, determining whether the current bulk grain storage environment data of the storage area meets the preset bulk grain storage conditions; Among them, bulk grain refers to grain that is directly stacked without packaging, such as bulk wheat or corn; the current bulk grain storage environment data is used to represent the real-time environmental parameters of the storage area, such as temperature, humidity, CO2 concentration, etc.; the preset bulk grain storage conditions refer to the ideal storage environment parameter range set in advance to ensure the quality of bulk grain.

[0048] When the storage information obtained by the control system through step S501 shows that bulk grain is placed in the storage area, the control system will execute step S504. Specifically, the control system first collects data from sensors in real time. These sensors may include temperature sensors, humidity sensors, gas concentration sensors, etc., to form the current bulk grain storage environment data. At the same time, the control system will call up the preset bulk grain storage conditions, which may vary depending on factors such as grain type, season, storage time, etc. Subsequently, the control system uses a preset algorithm to determine whether the current bulk grain storage environment data in the storage area meets the preset bulk grain storage conditions. For example, whether the temperature is within the allowable range, whether the humidity is below the critical value, whether the CO2 concentration is normal, etc. Through this series of judgments, the control system can comprehensively evaluate and determine whether the current bulk grain storage environment data in the storage area meets the preset bulk grain storage conditions.

[0049] S505. If not satisfied, a bulk grain storage environment adjustment instruction is sent to the environment control device, where the bulk grain storage environment adjustment instruction includes an environment operation mode.

[0050] Among them, environmental control equipment refers to various equipment used to adjust the environment of the storage area, such as refrigerators, dehumidifiers, ventilators, etc.; bulk grain storage environment adjustment instructions refer to specific instructions sent to environmental control equipment to adjust the storage environment; environmental operation mode is used to indicate the specific working status and parameter settings of environmental control equipment, such as cooling mode, dehumidification mode, ventilation mode, etc.

[0051] When the control system determines in step S504 that the current bulk grain storage environment data does not meet the preset bulk grain storage conditions, step S505 will be immediately executed. For example, if the temperature is too high, the control system will choose to start the cooling mode; if the humidity is too high, the control system will choose the dehumidification mode. After determining the required environmental operation mode, the control system will send the bulk grain storage environment adjustment instruction containing the environmental operation mode to the environmental control device.

[0052] By adopting the above technical solution, first, the control system obtains the storage information of the storage area and accurately distinguishes packaged grains from bulk grains. Then, the control system determines whether the current environmental data of the storage area meets the storage requirements of packaged grains or bulk grains. If not, the control system adjusts the current environmental data of the storage area according to the most suitable storage conditions for packaged grains or bulk grains, so that packaged grains or bulk grains can be stored in a suitable environment, effectively preventing the quality of grains from deteriorating, deteriorating and being damaged due to improper storage environment, and greatly improving the overall efficiency and quality of grain storage. For example, for packaged rice, the temperature and humidity can be accurately controlled; for bulk wheat grains, the temperature and moisture can be reasonably adjusted to prevent mildew. In short, this method successfully breaks the boundary between packaged grain and bulk grain storage. Both packaged grain and bulk grain can be stored in the same granary, saving resources, improving storage efficiency, and reducing losses, thereby realizing more intelligent and differentiated storage management.

[0053] The following is a supplement to the scenario of this embodiment.

[0054] With the continuous operation of environmental control equipment, the management level of the granary has been further improved. By analyzing the long-term accumulated environmental control logs, the control system found that under certain weather conditions, the temperature and humidity of the granary changed more dramatically. Based on this discovery, the control system automatically adjusted the equipment adjustment table and set more active preventive control measures for the granary. For example, when heavy rainfall is forecast, the control system will start the dehumidification equipment in advance, effectively preventing the impact of the sudden increase in humidity on grain. In addition, the control system also discovered the abnormal decline in the efficiency of a device in time by comparing and analyzing the operating parameters of each device. When the operating parameters of the device deviate to a certain extent, the control system automatically sends a maintenance notice to the maintenance personnel, avoiding the failure of environmental control caused by the operation of the equipment with illness. This ability of continuous optimization and active prevention not only further improves the safety and quality of grain storage, but also significantly extends the service life of the equipment and reduces the overall operating cost.

[0055] After combining the above scenarios, the following is a more detailed description of the process of the method provided by this implementation. Figure 6 , is another schematic flow chart of the bulk grain storage method in the embodiment of the present application.

[0056] S601, obtaining storage information of a storage area; For details, please refer to step S501, which will not be described in detail here.

[0057] S602, when the storage information shows that packaged grain is placed in the storage area, determining the optimal storage condition according to the type of packaged grain and a preset grain type-storage condition correspondence table; For details, please refer to step S502, which will not be described in detail here.

[0058] S603, if the current packaged grain storage environment data of the storage area does not meet the optimal storage conditions, sending a packaged grain storage environment adjustment instruction to the environment control device, the current packaged grain storage environment data includes the current packaged grain storage temperature and the current packaged grain storage humidity, and the packaged grain storage environment adjustment instruction includes an environment adjustment parameter; For details, please refer to step S503, which will not be described in detail here.

[0059] S604, when the storage information shows that bulk grain is placed in the storage area, determining whether the current bulk grain storage environment data of the storage area meets the preset bulk grain storage conditions; For details, please refer to step S504, which will not be described in detail here.

[0060] S605. If not, search for an environmental control equipment control strategy that matches the current bulk grain storage environment data according to the equipment adjustment table; The equipment adjustment table refers to a preset data table used to store the control strategies of environmental control equipment required under different environmental conditions compared with the preset bulk grain storage conditions. The control strategy of environmental control equipment refers to the specific plan on how to operate the environmental control equipment under specific environmental conditions, which may include the equipment start-up sequence, operating parameters, working hours, etc.

[0061] When the control system detects that the current bulk grain storage environment data of the storage area does not meet the preset bulk grain storage conditions, it needs to determine the control strategy of the environmental control equipment. Specifically, the control system will access the equipment adjustment table, which may be a multidimensional matrix, with the horizontal axis representing different environmental parameter ranges and the vertical axis representing different environmental control equipment. The table content is the corresponding environmental control equipment control strategy.

[0062] The control system will match the current bulk grain storage environment data with the environmental parameter range in the equipment adjustment table. For example, if the current bulk grain storage temperature is 25°C and the current bulk grain storage humidity is 65%, the control system may look for the row "Temperature range: 23-27°C, Humidity range: 60-70%" in the equipment adjustment table. After finding the matching row, the control system will read the environmental control equipment control strategy corresponding to the row. This environmental control equipment control strategy may be "Start the dehumidifier and set the target humidity to 60%; turn on the ventilator and set the ventilation frequency to 2 times per hour."

[0063] S606, determining the environment operation mode according to the control strategy of the environment control equipment; The environmental operation mode represents the overall working state of the environmental control equipment and is used to describe the way in which multiple environmental control equipment work together. After the control system determines the control strategy of the environmental control equipment according to the equipment adjustment table, it is necessary to convert this control strategy of the environmental control equipment into a specific environmental operation mode. Specifically, the control system first analyzes the obtained control strategy of the environmental control equipment, which may contain multiple control requirements, such as "lower the temperature by 2°C, reduce the humidity by 5%, and increase the number of ventilation times." Then, the control system determines the environmental control equipment that needs to be started and its environmental operation parameters.

[0064] For example, if the environmental control strategy requires cooling and dehumidification, the control system may select "Summer Mode" as the environmental operating mode. In this environmental operating mode, the air conditioner will be set to cooling mode and the temperature will be set to the target temperature; the dehumidifier will be activated and set to the target humidity; and the ventilator may be set to run at a low speed to assist in air circulation.

[0065] If the control strategy of the environmental control equipment focuses on humidity control, the control system may select "dehumidification mode" as the environmental operation mode. In this environmental operation mode, the dehumidifier will become the main operating device and set to the target humidity; the air conditioner may run at low power, mainly to maintain a stable temperature; the ventilator may be set to run intermittently to balance the indoor and outdoor air.

[0066] S607, based on a preset equipment-valve-opening correspondence table, according to the environmental operation mode, determining multiple valves associated with each environmental control equipment and the openings of the multiple valves; Among them, the equipment-valve-opening correspondence table refers to a preset data table for storing the correspondence between environmental control equipment, related valves and their openings. Environmental control equipment refers to various equipment used to adjust the environment of the storage area, such as air conditioners, dehumidifiers, ventilators, etc. Valve refers to a device that controls the flow of fluid, used to adjust the flow of air or liquid. The opening of the valve indicates the degree of opening of the valve, usually expressed as a percentage, such as 0% means fully closed, and 100% means fully open.

[0067] After the control system determines the environmental operation mode, it needs to further refine the specific operating parameters of each environmental control device. Specifically, the control system first accesses the preset device-valve-opening correspondence table. This table may be a multi-dimensional matrix, which contains the recommended openings of each environmental control device and its related valves under different environmental operation modes.

[0068] For example, if the current environment operation mode is "Summer Dehumidification Mode", the control system will search for the row corresponding to this environment operation mode in the table. This row may contain the following information: Air conditioning: condensate discharge valve opening 80%, refrigerant circulation valve opening 60%; Dehumidifier: air inlet valve opening 100%, drain valve opening 50%; Ventilator: fresh air inlet valve opening 30%, exhaust valve opening 40%; Based on this information, the control system determines the specific valves that need to be adjusted and their openings. In this example, the control system identifies the six valves that need to be adjusted and records their respective target openings.

[0069] S608, determining the opening and closing states of the multiple valves according to the opening degrees of the multiple valves; The open and closed state of a valve indicates whether the valve is open or closed, which is a binary state. Multiple valves refer to multiple control valves used to control different equipment or pipelines, which may include condensate discharge valves, refrigerant circulation valves, air intake valves, drain valves, etc. There is a corresponding relationship between the opening degree and the open and closed state, which is usually preset.

[0070] After the control system determines the opening of each valve according to the environmental operating mode and the equipment-valve-opening correspondence table, it needs to convert these continuous opening values ​​into discrete open and closed states. Specifically, the control system will evaluate the opening of each valve. Usually, the control system will preset a threshold, such as 20%. If the opening of the valve is greater than or equal to this threshold, the state of the valve is judged as "open"; if the opening is less than this threshold, it is judged as "closed".

[0071] S609, sending the bulk grain storage environment adjustment instruction including the environment operation mode to the environment control device; The control system establishes a communication connection with the environmental control equipment and sends the bulk grain storage environment adjustment instruction including the environmental operation mode to the environmental control equipment.

[0072] S610, after the environmental control device works for a preset period of time, obtaining current environmental data of the storage area; After the environmental control equipment has been working for a preset time in accordance with the determined environmental operation mode, the control system will obtain the current environmental data of the storage area again. The preset time is usually determined based on historical experience and may vary depending on the size of the warehouse and the environmental adjustment parameters. For example, for large storage warehouses, it may take longer to see obvious environmental changes, and the preset time can be set to 2-3 hours; for small storage rooms, the effect may be seen in 30 minutes to 1 hour, and the temperature adjustment may take a longer time to take effect, and the preset time can be 30 minutes to 1 hour; the humidity and airflow adjustment effects may appear faster, and the preset time may only take 10 to 15 minutes.

[0073] S611. When the current environmental data does not meet the preset bulk grain storage conditions, based on the equipment operation time extension rule table, extend the working time of the environmental control equipment; If the current environmental data does not meet the preset bulk grain storage conditions, it means that the storage area at this time is not suitable for bulk grain storage, and the environmental control equipment is needed to adjust the environment of the storage area. The control system can extend the working time of the environmental control equipment based on the equipment operating time extension rule table. The equipment operating time extension rule table is used to instruct the control system to extend the working time of the environmental control equipment. For example, when the current environmental data does not meet the preset bulk grain storage conditions, the environmental control equipment is set to extend the working time of the specific mode by 5 minutes. If the storage area still does not meet the preset bulk grain storage conditions after five minutes, the environmental control equipment will continue to be extended by 5 minutes, and so on.

[0074] S612. When the current environmental data reaches the preset bulk grain storage conditions, the environmental control equipment is adjusted to the default mode based on the equipment adjustment table; If the current environmental data has reached the preset bulk grain storage conditions, it means that the storage environment is now suitable for storing bulk grains. You only need to maintain the current environment without making any adjustments. The control system can adjust the environmental control equipment to the default mode based on the preset equipment adjustment table, that is, maintain a certain temperature, humidity, airflow direction and airflow speed. This can avoid unnecessary energy consumption, extend equipment life and reduce maintenance costs.

[0075] S613. During the operation of the environmental control equipment, periodically record environmental data and equipment operation parameters to obtain an environmental control log; During the operation of the environmental control equipment, the control system continuously collects and records various environmental data and equipment operating parameters to form a detailed environmental control log. Environmental data may include but are not limited to temperature, humidity, air flow speed, air flow direction, carbon dioxide concentration, etc. These environmental data are usually collected by sensors distributed throughout the storage area and sampled at a fixed frequency (such as every minute or every 5 minutes). Equipment operating parameters include the working power, operating time, and opening of each valve of cooling equipment, dehumidification equipment, and ventilation equipment. These equipment operating parameters directly reflect the working status and energy consumption of the environmental control equipment. The control system will organize the environmental data and equipment operating parameters into structured log records at preset time intervals, namely the environmental control log. The environmental control log includes not only the original environmental data and equipment operating parameters, but also some calculated indicators, such as temperature change rate, energy efficiency, etc. The environmental control log is usually saved in a format that is easy to store and analyze (such as CSV or JSON), stored in a local database, or uploaded to a cloud server, which is crucial for subsequent system optimization and fault diagnosis.

[0076] S614. If the equipment operating parameters of the environmental control equipment do not meet the standard equipment operating parameters, send equipment maintenance information to the user; If the equipment operating parameters of the environmental control equipment do not meet the standard equipment operating parameters, it means that there is an abnormality in the environmental control equipment and it may need maintenance. The specific situation requires further inspection. The control system establishes a communication connection with the user and then sends equipment maintenance information to the user.

[0077] S615. Based on the environment control log, adjust the equipment adjustment table to improve the operation efficiency of the environment control equipment.

[0078] Based on the environmental control log determined in step S613, the control system analyzes and optimizes the existing equipment adjustment rule table. This is a continuous improvement process aimed at continuously improving the operating efficiency of environmental control equipment. The control system may use some advanced data analysis techniques, such as machine learning algorithms, to discover patterns and trends from a large amount of historical data. For example, the control system finds that under certain specific external meteorological conditions, a certain equipment operation mode can reach the target environmental parameters faster or consume less energy. Based on these findings, the control system automatically adjusts the equipment adjustment rule table, including modifying the thresholds of certain environmental parameters, adjusting the order or timing of starting environmental control equipment, changing the coordination strategy between different devices, etc. For a specific example, the control system finds that during the high temperature period in summer, if the dehumidification equipment is run for a period of time before starting the refrigeration equipment, the energy consumption will be lower. Then, the control system will add such a new rule to the equipment adjustment rule table. Alternatively, the control system finds that a certain model of fan is more efficient when running at a low speed, so the default operating speed of the fan will be adjusted. After each adjustment, the control system will continue to collect new environmental data and equipment operating parameters, and then analyze and optimize again. In this way, over time, the equipment adjustment rule table will become more and more sophisticated and more and more efficient.

[0079] Due to the adoption of a dynamic optimization mechanism based on the equipment adjustment table and the environmental control log, it is possible to continuously improve environmental control measures and improve equipment operating efficiency, effectively solving the problem of fixed-mode operation of environmental control equipment in the prior art and difficulty in adapting to complex and changing environments, thereby achieving adaptive optimization of grain storage environmental control. This method can promptly discover and correct unreasonable environmental control plans by continuously recording and analyzing environmental data and equipment operating parameters, avoiding energy waste and reduced storage quality caused by excessive or insufficient control. At the same time, through the long-term accumulation of data and experience, the control system can gradually form a more accurate and efficient environmental control plan, and continuously improve the scientific and refined level of grain storage.

[0080] Due to the combination of multi-level control and automated maintenance, the storage environment can be precisely controlled and the equipment can be maintained in a timely manner, which effectively solves the problem that it is difficult for manual management to timely discover and deal with environmental anomalies and equipment failures in the existing technology, thereby realizing intelligent supervision of the entire grain storage process. This method can flexibly adjust the storage environment according to actual conditions by setting up a multi-level control mechanism, such as environmental adjustment parameters, equipment operation mode, valve opening, etc. At the same time, by automatically comparing equipment operation parameters with standard equipment operation parameters, potential faults can be discovered in a timely manner and maintenance information can be pushed, greatly improving equipment management efficiency and reliability. This not only reduces labor costs, but more importantly, it maximizes the safety and stability of grain storage.
