Description

Technical Field

[0001] This invention relates to the technical field of temperature and humidity control for refrigerated cabinets, specifically to a dual closed-loop control system and method for temperature and humidity control in a medical refrigerated cabinet for marine use. Background Technology

[0002] The temperature and humidity control technology for marine medical refrigerators employs a highly reliable dual-closed-loop control system to cope with the harsh environment at sea, including high temperatures and humidity, vibration, and tilting. The core of the system consists of a sensing layer, a control layer, and an execution layer: the sensing layer uses redundantly arranged medical-grade temperature and humidity sensors for real-time and accurate monitoring; the system integrates multiple safety designs and remote IoT monitoring, possessing wide voltage adaptability, resistance to salt spray corrosion, and seismic reinforcement characteristics. It can maintain the internal environment of the refrigerator stably within a narrow range required for drug storage under complex operating conditions, ensuring the storage safety and quality traceability compliance of critical medical supplies such as vaccines and blood products throughout the entire voyage. However, existing dual-closed-loop temperature and humidity control systems for marine medical refrigerators cannot intelligently formulate temperature and humidity adjustment strategies based on the ship's ambient temperature and humidity and the refrigerator's temperature and humidity parameters, nor can they adaptively control the temperature and humidity adjustment status based on changes in the ship's ambient temperature and humidity, thus reducing the quality and efficiency of temperature and humidity control in marine medical refrigerators.

[0003] Chinese invention patent CN120926687B, published on December 2, 2025, discloses a multi-temperature zone coordinated refrigeration system and energy-saving control method for variable-temperature cold storage. Based on the acquired initial real-time monitoring dataset, a dynamic load prediction model is invoked to calculate the heat load change trend data for each temperature zone over a preset period. Combining the heat load trend with the temperature and humidity requirements of the goods, the electronic expansion valve is adjusted, and start-up control commands are generated to start, stop, or switch the refrigeration units to operate the system. During system operation, a central oil circuit management module is activated to monitor the compressor oil level and compare it with a preset safety threshold to generate oil circuit adjustment commands. The intelligent oil pump is activated according to the commands to deliver oil, and simultaneously, the evaporator outlet superheat or pressure value is used as a feedback signal to control the electronic expansion valve in a closed loop. The data from the actuators and sensors are summarized and fed back to the central controller, forming a closed loop. However, the above technical solution cannot comprehensively determine the optimal multi-temperature zone refrigeration scheme for cold storage based on both ambient temperature and the cold storage's regulated temperature. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing dual-closed-loop temperature and humidity control systems for shipboard medical refrigerators, which cannot intelligently formulate temperature and humidity adjustment strategies based on the ship's ambient temperature and humidity and the refrigerator's adjustment parameters, nor can they adaptively control the refrigerator's temperature and humidity adjustment status based on changes in the ship's ambient temperature and humidity, this new system aims to achieve the following: real-time acquisition of ambient temperature and humidity data, current and target temperature and humidity data of the refrigerator; dynamic assessment of the refrigerator's temperature and humidity adjustment needs; intelligent formulation of real-time temperature and humidity adjustment plans; accurate execution of real-time temperature and humidity adjustment operations; accurate acquisition of temperature and humidity adjustment status information from the refrigerator's control terminal; precise monitoring of the completion status of real-time temperature and humidity adjustment operations; and ultimately, improved quality and efficiency of temperature and humidity regulation for shipboard medical refrigerators.

[0006] (II) Technical Solution

[0007] This invention is achieved through the following technical solution: a dual closed-loop control method for temperature and humidity in a shipboard medical refrigerator, the method comprising the following steps:

[0008] The system collects temperature and humidity data of the ship's operating environment, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. It then assesses and processes the temperature and humidity adjustment needs of the ship's medical refrigerator, obtaining adjustment demand information. If there is no demand, the current temperature and humidity adjustment operation is terminated. If there is demand, a real-time temperature and humidity adjustment plan is formulated based on the ship's operating environment temperature and humidity parameters, the current and target temperature and humidity parameters of the medical refrigerator, resulting in real-time temperature and humidity adjustment plan data for the ship's medical refrigerator. The system performs real-time temperature and humidity adjustment of the ship's medical refrigerator; it collects temperature and humidity adjustment status information from the control terminal of the medical refrigerator, judges and processes the completion status of the real-time temperature and humidity adjustment operation, and obtains the completion status judgment information of the real-time temperature and humidity adjustment operation; if it is not completed, it continues to perform the real-time temperature and humidity adjustment operation until it is completed; if it is completed, it cycles through the temperature and humidity adjustment operation until the temperature and humidity adjustment requirement judgment information of the medical refrigerator is no requirement, and then directly ends the current temperature and humidity adjustment operation of the ship's medical refrigerator.

[0009] Preferably, the following steps are taken: First, collect temperature and humidity data of the ship's operating environment, current temperature and humidity data of the medical refrigerator, and target temperature and humidity data of the medical refrigerator. Then, assess and process the temperature and humidity adjustment needs of the ship's medical refrigerator to obtain temperature and humidity adjustment need assessment information. If there is no need, the operation of directly ending the temperature and humidity adjustment of the ship's medical refrigerator is as follows:

[0010] The system collects temperature and humidity data of the geographical environment of the ship in which the medical refrigerator is located during its journey online using temperature and humidity sensors, and generates temperature and humidity data of the ship's sailing environment. It also collects current temperature and humidity data of the refrigerated space inside the medical refrigerator online using temperature and humidity sensors, and generates current temperature and humidity data of the medical refrigerator. Finally, it obtains target temperature and humidity data of the refrigerated space inside the medical refrigerator online through the control terminal of the medical refrigerator, based on the settings of the refrigerated medical supplies, and generates target temperature and humidity data of the medical refrigerator.

[0011] Based on the current temperature and humidity data of the medical refrigerator and the target temperature and humidity data of the medical refrigerator, the temperature and humidity adjustment needs of the ship's medical refrigerator are judged and processed to obtain the temperature and humidity adjustment needs judgment information of the medical refrigerator. The temperature and humidity adjustment needs judgment information of the medical refrigerator includes no need and need. When the temperature and humidity adjustment needs judgment information of the medical refrigerator is no need, the current temperature and humidity adjustment operation of the ship's medical refrigerator is directly terminated.

[0012] Preferably, based on the current temperature and humidity data of the medical refrigerator and the target temperature and humidity data of the medical refrigerator, the temperature and humidity adjustment needs of the ship's medical refrigerator are determined to obtain temperature and humidity adjustment need information. The temperature and humidity adjustment need information includes no need and need. When the temperature and humidity adjustment need information is no need, the operation steps to directly end the current temperature and humidity adjustment operation of the ship's medical refrigerator are as follows:

[0013] The current temperature and humidity data of the medical refrigerator are compared with the target temperature and humidity data of the medical refrigerator. Based on the comparison results, the temperature and humidity adjustment needs of the medical refrigerator are determined.

[0014] When the current temperature and humidity data of the medical refrigerator are consistent with the target temperature and humidity data of the medical refrigerator, it means that the temperature and humidity of the internal refrigeration space of the ship's medical refrigerator have been adjusted to the required refrigeration temperature and humidity for refrigerating medical supplies. Then, the temperature and humidity adjustment requirement judgment information of the medical refrigerator is output as no requirement, and the current temperature and humidity adjustment operation of the ship's medical refrigerator is directly ended.

[0015] When the current temperature and humidity data of the medical refrigerator are inconsistent with the target temperature and humidity data of the medical refrigerator, it indicates that the temperature and / or humidity of the internal refrigeration space of the medical refrigerator has not been adjusted to the required refrigeration temperature and / or humidity for refrigerating medical supplies. In this case, the temperature and humidity adjustment requirement judgment information of the medical refrigerator is output as "requirement exists".

[0016] Preferably, when needed, a real-time temperature and humidity control scheme for the ship's medical refrigerator is formulated based on the ship's ambient temperature and humidity parameters, the current temperature and humidity parameters of the medical refrigerator, and the target temperature and humidity parameters. The operation steps for obtaining the real-time temperature and humidity control scheme data for the ship's medical refrigerator and executing the real-time temperature and humidity control operation are as follows:

[0017] When the temperature and humidity adjustment requirement information of the medical refrigerator indicates that there is a requirement, the real-time temperature and humidity adjustment scheme of the medical refrigerator is formulated based on the temperature and humidity data of the ship's sailing environment, the current temperature and humidity data of the medical refrigerator, the target temperature and humidity data of the medical refrigerator, and the data matrix of temperature and humidity adjustment schemes for medical refrigerators under different refrigeration conditions, to obtain the real-time temperature and humidity adjustment scheme data of the medical refrigerator.

[0018] The real-time temperature and humidity control scheme data for the shipborne medical refrigerator is used to perform real-time temperature and humidity control operations for the shipborne medical refrigerator.

[0019] Preferably, when the temperature and humidity adjustment requirement information for the medical refrigerator indicates a requirement, the following steps are taken to formulate a real-time temperature and humidity adjustment plan for the medical refrigerator based on the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, the target temperature and humidity data of the medical refrigerator, and a data matrix of temperature and humidity adjustment schemes for medical refrigerators under different refrigeration conditions.

[0020] When the temperature and humidity control requirement assessment information for the medical refrigerator indicates a need, a data matrix of temperature and humidity control schemes for marine medical refrigerators under different refrigeration conditions is established. ,in Indicates the first This document presents data on temperature and humidity control schemes for ship-based medical refrigerators under various refrigeration conditions. The refrigeration condition type represents the actual operating environment state of the ship's medical refrigerator, primarily determined by multiple state parameters including the ship's ambient temperature and humidity, the current temperature and humidity of the medical refrigerator, and the target temperature and humidity of the medical refrigerator. The data on temperature and humidity control schemes for ship-based medical refrigerators under different refrigeration conditions represents the optimal temperature and humidity control schemes set for different types of refrigeration conditions. These schemes include the operating frequency and time of the refrigeration equipment or heating device for dual closed-loop temperature and humidity control of the refrigerator, the duty cycle and operating time of the dehumidification device or humidification device's modulation pulse, and the duty cycle and operating time of the circulating fan's modulation pulse.

Data on temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions described in the document. The system compares the temperature and humidity values ​​of the ship's operating environment, the current temperature and humidity of the medical refrigerator, and the target temperature and humidity of the medical refrigerator. It then searches for the corresponding temperature and humidity control schemes for ship-based medical refrigerators under different refrigeration conditions, based on the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The real-time temperature and humidity control scheme data for shipboard medical refrigerators was constructed. The specific steps for generating the real-time temperature and humidity control scheme data for shipboard medical refrigerators are as follows:

[0022] Step 2121: The generation of a female pygmy meerkat leader through a search for temperature and humidity control schemes; the search for female pygmy meerkat leaders in the data matrix of temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions. The search space is generated by foraging scout groups. Within each foraging scout group, the search for female dwarf meerkats is based on probability, with the probability calculated using the following formula: ;in This represents the probability that the female dwarf meerkat in the s-th temperature and humidity regulation scheme search becomes the female leader of the dwarf meerkat search in the temperature and humidity regulation scheme search. denoted as the fitness value of the s-th female pygmy meerkat in the temperature and humidity control scheme search, O represents the total number of individuals in the pygmy meerkat population in the temperature and humidity control scheme search, and the data matrix of the temperature and humidity control schemes for ship medical refrigerators under different refrigeration conditions.

This represents the data matrix of temperature and humidity control schemes for searching dwarf meerkats under different refrigeration conditions in a foraging and scouting team. The position in the search space;

[0024] Step 2123, Nanny Exchange; Based on the nanny exchange conditions, reset the temperature and humidity control schemes in the foraging and scouting groups and the nanny group to search for dwarf meerkats; the nanny exchange conditions are used to reset the temperature and humidity control schemes in the foraging and scouting groups and the nanny group to search for dwarf meerkats. When members of the foraging and scouting group are in the data matrix of temperature and humidity control schemes for ship medical refrigerators under different refrigeration conditions... The search space could not find data on temperature and humidity control schemes for ship medical refrigerators under different refrigeration conditions that matched the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. When searching for food, the temperature and humidity regulation schemes of the foraging scout group and the caretaker group will be exchanged to search for individual dwarf meerkats. After the exchange conditions are met, the individual dwarf meerkats searching for temperature and humidity regulation schemes in the foraging scout group will simultaneously forage for food and search for sleeping sites. The formula for updating the location of dwarf meerkats searching for temperature and humidity regulation schemes is as follows: ,in This represents the data matrix of temperature and humidity control schemes for dwarf meerkats under different refrigeration conditions in marine medical refrigerators after the exchange. A new location in the search space. and These represent the data matrix of temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions. The upper and lower bounds of the search space; random numbers in the range [0,1] of rand; the temperature and humidity control scheme in the foraging and scouting group after the nanny exchange; the search for dwarf meerkats according to step 2122 in the data matrix of the temperature and humidity control scheme for ship medical refrigerators under different refrigeration conditions. The search area is used for foraging and simultaneously foraging for sleeping sites, which are resting places for individual pygmy meerkats. These individuals exhibit a lifestyle pattern of not returning to previous sleeping sites, preventing overexploitation of the search area. The data matrix for the temperature and humidity control scheme of the pygmy meerkats under different refrigeration conditions is described in the following formula. The search space is used to search for temperature and humidity control schemes for ship medical refrigerators under different refrigeration conditions that match the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The mathematical formula for finding new sleeping locations for dwarf meerkats using temperature and humidity control schemes is as follows: ,in This represents a data matrix indicating the search for temperature and humidity control schemes for dwarf meerkats under different refrigeration conditions in marine medical refrigerators.

[0025] Step 2124: When the algorithm reaches the maximum number of iterations, output the temperature and humidity adjustment scheme data for the ship's medical refrigerator under different refrigeration conditions, which matches the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. ;

[0026] Step 2125: Calculate the temperature and humidity control scheme data for the shipborne medical refrigerator under different refrigeration conditions, which is output in step 2124 and matches the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The system generates real-time temperature and humidity control scheme data for shipboard medical refrigerators through data identification. This data represents the operating frequency and time of the refrigeration equipment or heating device for dual closed-loop control of temperature and humidity in the refrigerator, the duty cycle and time of the dehumidification device or humidification device, and the duty cycle and time of the circulating fan, based on the current shipboard operating environment temperature and humidity, the current temperature and humidity of the medical refrigerator, and the set target temperature and humidity of the medical refrigerator.

[0027] Preferably, the operation steps for performing real-time temperature and humidity adjustment of the ship's medical refrigerator based on the data from the real-time temperature and humidity adjustment scheme are as follows:

[0028] The medical refrigerator control terminal controls the refrigeration equipment or heating device, dehumidification device or humidification device and circulating fan in the medical refrigerator to perform real-time temperature and humidity dual closed-loop regulation operation based on the real-time temperature and humidity regulation scheme data of the medical refrigerator.

[0029] Preferably, the following steps are taken: First, collect the temperature and humidity adjustment status information from the control terminal of the medical refrigerator. Then, process the judgment on the completion status of the real-time temperature and humidity adjustment operation of the ship's medical refrigerator to obtain the completion status judgment information. If not completed, continue executing the real-time temperature and humidity adjustment operation until completion. If completed, cyclically execute the temperature and humidity adjustment operation until the temperature and humidity adjustment requirement judgment information of the medical refrigerator indicates no requirement, and then directly end the current temperature and humidity adjustment operation of the ship's medical refrigerator.

[0030] During the real-time temperature and humidity adjustment operation of the ship's medical refrigerator, the status text information of the temperature and humidity adjustment process of the ship's medical refrigerator is collected online through the control terminal of the medical refrigerator, and the temperature and humidity adjustment status information of the control terminal of the medical refrigerator is generated. The temperature and humidity adjustment status information of the control terminal of the medical refrigerator represents the result feedback text information of the completion status and incomplete status of the temperature and humidity adjustment process of the ship's medical refrigerator.

[0031] Based on the temperature and humidity adjustment status information of the medical refrigerator control terminal and the keyword matrix of the temperature and humidity adjustment completion status of the medical refrigerator control terminal, the completion status judgment process of the real-time temperature and humidity adjustment operation of the ship's medical refrigerator is performed to obtain the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator.

The medical refrigerator control terminal temperature and humidity adjustment completion status keywords include completed, process completed, ended, and executed.

[0034] A bidirectional search algorithm is used to combine the temperature and humidity adjustment status information of the medical refrigerator control terminal with the keyword matrix of the temperature and humidity adjustment completion status of the medical refrigerator control terminal. Keywords related to the completion status of temperature and humidity adjustment in the control terminal of the medical refrigerator described in the text. Perform text information matching, and generate information on the completion status of real-time temperature and humidity adjustment of medical refrigerator based on the text information matching results;

[0035] When the temperature and humidity adjustment status information of the medical refrigerator control terminal is consistent with the key words of the medical refrigerator control terminal temperature and humidity adjustment completion status. If the text information matching is successful, it means that the real-time temperature and humidity adjustment operation of the ship's medical refrigerator based on the real-time temperature and humidity adjustment scheme data has been completed. Then, the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator is output as "completed". At this time, the temperature and humidity adjustment operation of the ship's medical refrigerator is executed repeatedly until the temperature and humidity adjustment demand judgment information of the medical refrigerator is "no demand", and then the current temperature and humidity adjustment operation of the ship's medical refrigerator is directly terminated.

[0036] When the temperature and humidity adjustment status information of the medical refrigerator control terminal is consistent with the key words of the medical refrigerator control terminal temperature and humidity adjustment completion status. If text matching fails, it indicates that the real-time temperature and humidity adjustment operation of the ship's medical refrigerator based on the data of the real-time temperature and humidity adjustment scheme for the ship's medical refrigerator has not been completed. In this case, the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator is output as incomplete. At this time, the real-time temperature and humidity adjustment operation of the ship's medical refrigerator based on the data of the real-time temperature and humidity adjustment scheme for the ship's medical refrigerator continues to be executed until the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator is completed.

[0056] For further details, please refer to Figures 1-2 The system collects temperature and humidity data of the ship's operating environment, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. It then assesses and processes the temperature and humidity adjustment needs of the ship's medical refrigerator to obtain temperature and humidity adjustment need assessment information. When there is no need, the system directly terminates the current temperature and humidity adjustment operation of the ship's medical refrigerator. The operation steps are as follows:

[0057] Step 11: Collect temperature and humidity data of the geographical environment of the ship in which the medical refrigerator is located during its journey online using temperature and humidity sensors, and generate temperature and humidity data of the ship's journey environment. Collect current temperature and humidity data of the refrigerated space inside the medical refrigerator online using temperature and humidity sensors, and generate current temperature and humidity data of the medical refrigerator. Obtain target temperature and humidity data of the refrigerated space inside the medical refrigerator online through the control terminal of the medical refrigerator based on the settings of the refrigerated medical supplies, and generate target temperature and humidity data of the medical refrigerator.

[0058] Step 12: Based on the current temperature and humidity data and the target temperature and humidity data of the medical refrigerator, perform temperature and humidity adjustment requirement judgment processing for the ship's medical refrigerator to obtain temperature and humidity adjustment requirement judgment information. The temperature and humidity adjustment requirement judgment information includes no requirement and requirement. When the temperature and humidity adjustment requirement judgment information of the medical refrigerator is no requirement, the current temperature and humidity adjustment operation of the ship's medical refrigerator is directly terminated.

[0059] Based on the current temperature and humidity data and target temperature and humidity data of the medical refrigerator, the temperature and humidity adjustment needs of the ship's medical refrigerator are determined. This results in temperature and humidity adjustment need assessment information, which includes whether there is a need or not. When the assessment information indicates no need, the operation to directly terminate the temperature and humidity adjustment of the ship's medical refrigerator is as follows:

[0060] Step 121: Compare the current temperature and humidity data of the medical refrigerator with the target temperature and humidity data of the medical refrigerator. Based on the comparison results, generate the temperature and humidity adjustment requirement judgment information of the medical refrigerator.

[0061] When the current temperature and humidity data of the medical refrigerator are consistent with the target temperature and humidity data of the medical refrigerator, it means that the temperature and humidity of the internal refrigeration space of the ship's medical refrigerator have been adjusted to the required refrigeration temperature and humidity for refrigerating medical supplies. Then, the output of the medical refrigerator temperature and humidity adjustment requirement judgment information is no requirement, and the current ship's medical refrigerator temperature and humidity adjustment operation is directly ended.

[0062] When the current temperature and humidity data of the medical refrigerator are inconsistent with the target temperature and humidity data of the medical refrigerator, it indicates that the temperature and / or humidity of the internal refrigeration space of the medical refrigerator has not been adjusted to the required refrigeration temperature and / or humidity for refrigerating medical supplies. In this case, the output information of the medical refrigerator temperature and humidity adjustment requirement judgment is "there is a requirement".

[0063] By using temperature and humidity sensors to monitor the temperature and humidity of the ship's operating environment and the current temperature and humidity data of the medical refrigerator in real time, accurate data collection of the temperature and humidity of the ship's medical refrigerator and the environment is achieved. The target temperature and humidity parameters of the medical refrigerator are efficiently collected through the control terminal of the medical refrigerator, enabling precise acquisition of the target temperature and humidity parameters for the ship's medical refrigerator. Based on the current temperature and humidity data of the medical refrigerator, the target temperature and humidity data of the medical refrigerator, and combined with numerical analysis, the temperature and humidity adjustment needs of the ship's medical refrigerator are accurately monitored, achieving efficient and accurate identification of the temperature and humidity adjustment needs of the ship's medical refrigerator and improving the accuracy of the dual closed-loop control of temperature and humidity in the ship's medical refrigerator.

[0064] For further details, please refer to Figures 1-2 When needed, a real-time temperature and humidity control plan for the ship's medical refrigerator is formulated based on the ship's ambient temperature and humidity parameters, the current temperature and humidity parameters of the medical refrigerator, and the target temperature and humidity parameters. The operation steps for obtaining the real-time temperature and humidity control plan data for the ship's medical refrigerator and executing the real-time temperature and humidity control operation are as follows:

[0065] Step 21: When the information indicating a demand for temperature and humidity regulation of the medical refrigerator is that there is a demand, the real-time temperature and humidity regulation scheme for the medical refrigerator is formulated based on the temperature and humidity data of the ship's sailing environment, the current temperature and humidity data of the medical refrigerator, the target temperature and humidity data of the medical refrigerator, and the data matrix of temperature and humidity regulation schemes for medical refrigerators under different refrigeration conditions. This process yields the real-time temperature and humidity regulation scheme data for the medical refrigerator.

[0066] Step 22: Execute real-time temperature and humidity adjustment operations for the ship's medical refrigerator based on the real-time temperature and humidity control scheme data.

[0067] When the information indicating a need for temperature and humidity regulation in the medical refrigerator is that there is a need, the following steps are taken to formulate a real-time temperature and humidity regulation plan for the medical refrigerator: based on the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, the target temperature and humidity data of the medical refrigerator, and a data matrix of temperature and humidity regulation schemes for medical refrigerators on ships under different refrigeration conditions.

[0068] Step 211: When the temperature and humidity control requirement information for the medical refrigerator indicates a demand, establish a data matrix of temperature and humidity control schemes for marine medical refrigerators under different refrigeration conditions. ,in Indicates the first This document presents data on temperature and humidity control schemes for shipborne medical refrigerators under various refrigeration conditions. The refrigeration condition type represents the actual operating environment state of the shipborne medical refrigerator, primarily determined by multiple state parameters including the ship's ambient temperature and humidity, the current temperature and humidity of the medical refrigerator, and the target temperature and humidity of the medical refrigerator.

These schemes include the operating frequency and time of the refrigeration equipment or heating device used for dual closed-loop temperature and humidity control of the refrigerator, the duty cycle and operating time of the dehumidification device or humidification device's modulation pulse, and the duty cycle and operating time of the circulating fan's modulation pulse.

[0069] Step 212: Combine the ship's ambient temperature and humidity data, the current temperature and humidity data of the medical refrigerator, the target temperature and humidity data of the medical refrigerator, and the data matrix of temperature and humidity control schemes for shipborne medical refrigerators under different refrigeration conditions. Data on temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions The system compares the temperature and humidity values ​​of the ship's operating environment, the current temperature and humidity of the medical refrigerator, and the target temperature and humidity of the medical refrigerator. It then searches for temperature and humidity control schemes for ship-based medical refrigerators under different refrigeration conditions, corresponding to the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The real-time temperature and humidity control scheme data for shipboard medical refrigerators was constructed. The specific steps for generating the real-time temperature and humidity control scheme data for shipboard medical refrigerators are as follows:

[0070] Step 2121: The search for temperature and humidity control schemes leads to the generation of female pygmy meerkats; the search for temperature and humidity control schemes for female pygmy meerkats under different refrigeration conditions results in a data matrix for temperature and humidity control schemes in marine medical refrigerators. The search space is generated by foraging scout groups. Within each foraging scout group, the search for female dwarf meerkats is based on probability, with the probability calculated using the following formula: ;in This represents the probability that the female dwarf meerkat in the s-th temperature and humidity regulation scheme search becomes the female leader of the dwarf meerkat search in the temperature and humidity regulation scheme search. denoted by s, the fitness value of the s-th female pygmy meerkat in the temperature and humidity control scheme search, and O representing the total number of individuals in the pygmy meerkat population under different refrigeration conditions. The data matrix of pygmy meerkat individuals in the population under different refrigeration conditions is used in the ship's medical refrigerator temperature and humidity control scheme search. They were randomly divided into foraging and scouting groups and babysitting groups within the search space;

[0071] Step 2122: Members of the foraging and reconnaissance team forage for food; the foraging and reconnaissance team searches for data matrix of dwarf meerkats under different refrigeration conditions. The search space is used to search for food and find data on temperature and humidity control schemes for ship medical refrigerators under different refrigeration conditions that match the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The candidate locations of food sources are calculated using the following formula: ,in Indicates the first A data matrix of temperature and humidity control schemes for individual dwarf meerkats under different refrigeration conditions in marine medical refrigerators.

This represents a data matrix of temperature and humidity control schemes for searching individual dwarf meerkats under different refrigeration conditions within a foraging and scouting team. The position in the search space;

[0072] Step 2123, Nanny Exchange; Based on the nanny exchange conditions, reset the temperature and humidity control schemes in the foraging and scouting groups and the nanny group to search for dwarf meerkats; the nanny exchange conditions are used to reset the temperature and humidity control schemes in the foraging and scouting groups and the nanny group to search for dwarf meerkats. When members of the foraging and scouting group are in different refrigeration conditions, the data matrix of the temperature and humidity control schemes for ship medical refrigerators is used. The search space could not find data on temperature and humidity control schemes for ship medical refrigerators under different refrigeration conditions that match the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. When searching for food, the temperature and humidity regulation schemes of the foraging scout group and the caretaker group will be exchanged to search for individual dwarf meerkats. After the exchange conditions are met, the individual dwarf meerkats searching for temperature and humidity regulation schemes in the foraging scout group will simultaneously forage for food and search for sleeping sites. The formula for updating the location of dwarf meerkats searching for temperature and humidity regulation schemes is as follows: ,in This represents a data matrix showing the search results for temperature and humidity control schemes for dwarf meerkats under different refrigeration conditions in marine medical refrigerators. A new location in the search space. and These represent data matrices representing temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions. The upper and lower bounds of the search space; random numbers in the range [0,1] of rand; the temperature and humidity control scheme in the foraging and scouting group after the nanny exchange; the search for dwarf meerkats according to step 2122 under different refrigeration conditions; the data matrix of the temperature and humidity control scheme for ship medical refrigerators. The search area is used for foraging and simultaneously foraging for sleeping sites, which are resting places for individual pygmy meerkats. These individuals exhibit a lifestyle pattern of not returning to previous sleeping sites, preventing overexploitation of the search area. The search data matrix for pygmy meerkats under different refrigeration conditions is calculated using the following formula. Search the search space for data on temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions that match the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The mathematical formula for finding new sleeping locations for dwarf meerkats using temperature and humidity control schemes is as follows: ,in This represents a data matrix showing temperature and humidity control schemes for dwarf meerkats under different refrigeration conditions in marine medical refrigerators.

(Data matrix of temperature and humidity control schemes for marine medical refrigerators.) The new sleep locations searched in the search space are suitable for the mean; and ,in Indicates the first A data matrix of temperature and humidity control schemes for individual dwarf meerkats under different refrigeration conditions in marine medical refrigerators. The search space for a new suitable value for a sleep location; This indicates the control coefficient for the mobility of the dwarf meerkat population in the search for temperature and humidity regulation schemes. , where t represents the current iteration number and T is the maximum iteration number;

[0073] Step 2124: When the algorithm reaches the maximum number of iterations, output data on temperature and humidity control schemes for shipboard medical refrigerators under different refrigeration conditions, matching the ship's ambient temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. ;

[0074] Step 2125: Compile the temperature and humidity control scheme data for shipboard medical refrigerators under different refrigeration conditions, which are output in Step 2124 and matched with the ship's operating environment temperature and humidity data, the current temperature and humidity data of the medical refrigerator, and the target temperature and humidity data of the medical refrigerator. The system generates real-time temperature and humidity control scheme data for shipboard medical refrigerators through data identification. This data represents the operating frequency and time of the refrigeration equipment or heating device for dual closed-loop control of temperature and humidity in the refrigerator, the duty cycle and time of the dehumidification device or humidification device, and the duty cycle and time of the circulating fan, based on the current shipboard operating environment temperature and humidity, the current temperature and humidity of the medical refrigerator, and the set target temperature and humidity of the medical refrigerator.

[0075] The operational steps for performing real-time temperature and humidity control of shipboard medical refrigerators based on real-time temperature and humidity control scheme data are as follows:

[0076] Step 221: Based on the real-time temperature and humidity control scheme data of the medical refrigerator, the control terminal of the medical refrigerator controls the refrigeration equipment or heating device, dehumidification device or humidification device and circulating fan in the medical refrigerator to perform real-time temperature and humidity dual closed-loop regulation operation of the medical refrigerator.

[0077] By combining data on the ship's ambient temperature and humidity, the current temperature and humidity of the medical refrigerator, and the target temperature and humidity of the medical refrigerator, along with AI algorithms and data on temperature and humidity control schemes for different refrigeration conditions based on big data storage, intelligent and precise matching of real-time temperature and humidity control schemes for ship medical refrigerators is achieved. This enables intelligent planning of the optimal real-time dual-closed-loop temperature and humidity control scheme for the ship medical refrigerator based on multiple parameters including the ship's ambient temperature and the current and target temperature and humidity of the medical refrigerator, thereby improving the intelligence of the dual-closed-loop temperature and humidity control of the ship medical refrigerator. Based on the real-time temperature and humidity control scheme data of the ship medical refrigerator, and in conjunction with the medical refrigerator control terminal, refrigeration or heating device, dehumidification or humidification device, and circulating fan, the real-time temperature and humidity control of the ship medical refrigerator is autonomously and adaptively executed, thereby improving the reliability of the dual-closed-loop temperature and humidity control of the ship medical refrigerator.

[0078] For further details, please refer to Figures 1-2 The system collects temperature and humidity adjustment status information from the control terminal of the medical refrigerator, judges the completion status of the real-time temperature and humidity adjustment operation of the ship's medical refrigerator, and obtains the completion status judgment information of the real-time temperature and humidity adjustment operation. If it is not completed, the real-time temperature and humidity adjustment operation continues until it is completed. If it is completed, the temperature and humidity adjustment operation is repeated until the temperature and humidity adjustment requirement judgment information of the medical refrigerator is no longer needed, and the current temperature and humidity adjustment operation of the ship's medical refrigerator is terminated. The operation steps are as follows:

[0079] Step 31: During the real-time temperature and humidity adjustment operation of the ship's medical refrigerator, the status text information of the temperature and humidity adjustment process of the ship's medical refrigerator is collected online through the control terminal of the medical refrigerator, and the temperature and humidity adjustment status information of the control terminal of the medical refrigerator is generated. The temperature and humidity adjustment status information of the control terminal of the medical refrigerator represents the result feedback text information of the completion status and incomplete status of the temperature and humidity adjustment process of the ship's medical refrigerator.

[0080] Step 32: Based on the temperature and humidity adjustment status information of the medical refrigerator control terminal and the keyword matrix of the temperature and humidity adjustment completion status of the medical refrigerator control terminal, perform the completion status judgment processing of the real-time temperature and humidity adjustment operation of the ship's medical refrigerator to obtain the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator. The completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator includes incomplete and completed. When the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator is incomplete, continue to execute the real-time temperature and humidity adjustment operation of the medical refrigerator until it is completed. When the completion status judgment information of the real-time temperature and humidity adjustment operation of the medical refrigerator is completed, cyclically execute the temperature and humidity adjustment operation of the ship's medical refrigerator until the temperature and humidity adjustment demand judgment information of the medical refrigerator is no demand, and directly end the current temperature and humidity adjustment operation of the ship's medical refrigerator.

[0081] Based on the temperature and humidity adjustment status information and the keyword matrix of the temperature and humidity adjustment completion status of the medical refrigerator control terminal, the completion status judgment of the real-time temperature and humidity adjustment operation of the ship's medical refrigerator is processed to obtain the completion status judgment information of the real-time temperature and humidity adjustment operation. The completion status judgment information of the real-time temperature and humidity adjustment operation includes incomplete and completed. When the completion status judgment information of the real-time temperature and humidity adjustment operation is incomplete, the real-time temperature and humidity adjustment operation continues until it is completed. When the completion status judgment information of the real-time temperature and humidity adjustment operation is completed, the ship's medical refrigerator temperature and humidity adjustment operation is executed cyclically until the temperature and humidity adjustment demand judgment information of the medical refrigerator is no demand, and the current ship's medical refrigerator temperature and humidity adjustment operation is directly terminated. The operation steps are as follows:

[0082] Step 321: Establish a keyword matrix for the completion status of temperature and humidity regulation in the medical refrigerator control terminal. ,in Indicates the first The medical refrigerator control terminal temperature and humidity adjustment completion status keywords represent the standard medical refrigerator temperature and humidity adjustment status indicators used to provide feedback on the completion status of the dual closed-loop temperature and humidity adjustment operation of the ship's medical refrigerator. The medical refrigerator control terminal temperature and humidity adjustment completion status keywords include completed, process completed, ended, and executed.

[0083] Step 322: Use a bidirectional search algorithm to combine the temperature and humidity adjustment status information of the medical refrigerator control terminal with the keyword matrix of the temperature and humidity adjustment completion status of the medical refrigerator control terminal. Keywords for temperature and humidity adjustment completion status of TCM refrigerator control terminal Perform text information matching, and generate information on the completion status of real-time temperature and humidity adjustment of medical refrigerator based on the text information matching results;

[0084] When the temperature and humidity adjustment status information on the medical refrigerator control terminal is updated with the keywords indicating that the temperature and humidity adjustment has been completed. If the text information matching is successful, it means that the real-time temperature and humidity adjustment operation of the ship's medical refrigerator based on the real-time temperature and humidity adjustment scheme data has been completed. Then, the output of the real-time temperature and humidity adjustment operation completion status judgment information is "completed". At this time, the ship's medical refrigerator temperature and humidity adjustment operation is executed repeatedly until the temperature and humidity adjustment demand judgment information of the medical refrigerator is "no demand", and then the current ship's medical refrigerator temperature and humidity adjustment operation is directly terminated.

[0085] When the temperature and humidity adjustment status information on the medical refrigerator control terminal is updated with the keywords indicating that the temperature and humidity adjustment has been completed. If text matching fails, it indicates that the real-time temperature and humidity adjustment operation of the ship's medical refrigerator based on the real-time temperature and humidity adjustment scheme data has not been completed. In this case, the output status judgment information of the real-time temperature and humidity adjustment operation is "incomplete". At this time, the real-time temperature and humidity adjustment operation of the ship's medical refrigerator based on the real-time temperature and humidity adjustment scheme data continues to be executed until the status judgment information of the real-time temperature and humidity adjustment operation is "completed".

[0086] By dynamically collecting temperature and humidity adjustment status information from the medical refrigerator control terminal, timely acquisition of temperature and humidity dual closed-loop adjustment status information for the ship's medical refrigerator is achieved. Based on the temperature and humidity adjustment status information from the medical refrigerator control terminal, combined with intelligent search algorithms and standard stored keywords of the temperature and humidity adjustment completion status, precise negative feedback loop monitoring of the real-time temperature and humidity adjustment operation completion status of the ship's medical refrigerator is implemented. This achieves adaptive control and correction of the ship's medical refrigerator temperature and humidity dual closed-loop adjustment strategy based on temperature and humidity adjustment process status monitoring and preset target temperature and humidity thresholds, thereby improving the accuracy and intelligence of the ship's medical refrigerator temperature and humidity dual closed-loop control.
