Description

Technical Field

[0001] This invention belongs to the field of refrigerated transport warehouses, specifically an intelligent refrigeration control system for refrigerated transport warehouses. Background Technology

[0002] Cold chain transport warehouses are key equipment in the cold chain logistics system, primarily used to maintain the quality of perishable products such as fruits, vegetables, flowers, and live aquatic products during long-distance transportation. Traditional cold chain transport warehouses mostly use a single refrigeration method, slowing down the metabolic activities of fruits and vegetables by lowering the temperature, but this method has significant limitations. First, the temperature control precision is insufficient, resulting in large temperature fluctuations within the warehouse, which can easily cause chilling injury or frost damage to fruits and vegetables. Second, humidity management is lacking, leading to continuous moisture loss from fruits and vegetables during transportation, resulting in wilting, weight loss, and a decline in appearance quality. Third, the lack of effective gas control means that ethylene produced by the respiration of fruits and vegetables accumulates continuously, accelerating the ripening and aging process. In addition, microbial contamination is a prominent problem, with pathogens in the transportation environment easily causing spoilage. Summary of the Invention

[0003] This invention provides an intelligent preservation control system for a refrigerated transport warehouse to overcome the deficiencies in the prior art.

[0004] This invention is achieved through the following technical solution: An intelligent preservation control system for a refrigeration and transportation warehouse includes a refrigeration unit, a humidification unit, a hydroxyl disinfection unit, a respiration suppression unit, a data acquisition unit, a control unit, a storage unit, and a remote terminal. The refrigeration unit is used to stabilize the temperature inside the refrigerated transport compartment; The humidification unit is used to regulate the humidity environment inside the refrigerated transport warehouse; The hydroxyl-based sterilization and disinfection unit sterilizes and disinfects the inside of the refrigerated transport warehouse. The respiratory inhibition unit described above performs respiratory inhibition treatment on fruits and vegetables stored in the fresh-keeping transport warehouse; The data acquisition unit can acquire environmental data in the refrigerated transport warehouse in real time; The control unit can receive and analyze environmental data acquired by the data acquisition unit in real time, and can also control the humidification unit, the hydroxyl disinfection unit, and the respiratory suppression unit. The storage unit is used to store relevant data; The remote terminal can interact with the control unit.

[0005] The intelligent preservation control system for a refrigerated transport warehouse as described above includes a refrigeration unit that enables the refrigeration warehouse to maintain a specified temperature during transport. The control unit determines and adjusts the power of the refrigeration unit based on the temperature inside the refrigeration warehouse.

[0006] The intelligent preservation control system for a refrigerated transport warehouse, as described above, includes a humidification unit comprising a water tank, a high-pressure plunger pump, and a high-pressure atomizing nozzle. The high-pressure atomizing nozzle is installed inside the refrigerated transport warehouse. The control unit selects whether to activate the humidification unit to adjust the humidity based on the real-time humidity information of the refrigerated transport warehouse.

[0007] The intelligent preservation control system for a refrigerated transport warehouse, as described above, includes an ozone generator as part of a hydroxyl disinfection unit. The control unit controls the ozone generator to turn on and for a specific duration, thereby periodically disinfecting the refrigerated transport warehouse.

[0008] The intelligent preservation control system for a fresh-keeping transport warehouse as described above includes a respiration inhibition unit comprising a 1-MCP release device. The 1-MCP release device can release 1-methylcyclopropene gas into the fresh-keeping transport warehouse under the instruction of the control unit, thereby blocking the normal binding of ethylene with the fruits and vegetables transported in the fresh-keeping transport warehouse and effectively inhibiting the respiration of the fruits and vegetables.

[0009] The intelligent preservation control system for a refrigerated transport warehouse, as described above, uses sensors installed inside and outside the refrigerated transport warehouse to acquire data such as outside temperature, inside temperature, humidity, carbon dioxide concentration, chlorine dioxide concentration, oxygen content, nitrogen content, ozone concentration, ethylene concentration, warehouse positioning, vibration, and images of fruits and vegetables inside the warehouse.

[0010] The intelligent preservation control system for a fresh-keeping transportation warehouse, as described above, has a built-in environmental parameter threshold database and a fruit and vegetable preservation model in the control unit. The control unit compares and analyzes the real-time environmental data acquired by the data acquisition unit with the standard parameters in the threshold database. When a parameter is detected to deviate from the preset range, the corresponding control mechanism is automatically triggered.

[0011] The intelligent preservation control system for a fresh-keeping transport warehouse, as described above, includes a control unit equipped with different transport preservation schemes for different types of fruits and vegetables, allowing selection of the appropriate transport preservation scheme for different types of fruits and vegetables during transport.

[0012] In the intelligent preservation control system of the refrigerated transport warehouse described above, the data in the storage unit can be retrieved by the control unit, and the corresponding data will be uploaded to a remote terminal for backup after the transportation is completed.

[0013] As described above, in an intelligent preservation control system for a refrigerated transport warehouse, the remote terminal, upon receiving information from the control unit, can synchronously transmit it to the mobile phone or computer account of relevant personnel. This facilitates timely information access and handling by relevant personnel in case of abnormal issues. If a problem occurs during the automatic adjustment process of the control unit, relevant personnel can also provide feedback to the remote terminal, which will then issue instructions to the control unit to force corresponding adjustments. Furthermore, if a corresponding unit malfunctions, an error will be promptly reported, allowing relevant personnel to handle the situation in a timely manner.

[0014] The advantages of this invention are as follows: This invention constructs an IoT-based intelligent sensing and monitoring system covering the entire equipment process. Through IoT technology, it monitors the fruit and vegetable storage environment in real time, enabling real-time equipment monitoring and ensuring stable quality. This invention develops an intelligent application system that controls temperature, humidity, oxygen content, carbon dioxide content, and environmental microorganisms to intervene and control the release of ethylene within the product, inhibiting the effects of pectinase, cellulase, and polyphenol oxidase on the product, ensuring product quality, achieving long-term product preservation, and realizing precise environmental control during product transportation and storage. This invention constructs a database of various fruit and vegetable preservation models, providing pre-harvest spraying-assisted preservation solutions, post-harvest ambient temperature microecological preservation solutions, and post-harvest low-temperature microecological preservation solutions through agricultural systems engineering methods. This invention constructs a smart fruit and vegetable preservation information service platform composed of four subsystems: controlled atmosphere preservation technology, low-temperature preservation technology, biological preservation technology, and intelligent monitoring. This platform enables data collection, storage, analysis, and visualization, providing scientific monitoring support for equipment. This invention establishes an equipment safety traceability system, achieving full traceability of equipment circulation and other processes. Attached Figure Description
