Description

Technical Field

[0001] This invention belongs to the technical field of intelligent transportation equipment for agricultural products, specifically relating to an intelligent transportation warehouse for agricultural products with combined temperature, humidity and vibration regulation functions. Background Technology

[0002] Fresh agricultural products such as fruits, vegetables, berries, leafy greens, and edible fungi are typical high-respiration-rate, high-moisture-content, and easily perishable goods. In the complex and dynamic environment of vehicle-mounted cold chain transportation, temperature fluctuations, humidity imbalances, and random road vibrations constitute three coupled hazardous factors affecting product quality: abnormal temperatures accelerate respiration metabolism and ripening / aging; insufficient humidity causes transpiration water loss and wilting / shrinkage; and mechanical vibration directly causes cell wall rupture, epidermal mechanical damage, and browning of internal tissues. These three factors do not act in isolation but exhibit a chain-like amplification effect. Currently, the mainstream solution in the industry still uses insulated vehicle-mounted transport compartments as the core storage and transportation carrier. Although such equipment can maintain a relatively stable static temperature and humidity range with the help of insulated compartments and basic refrigeration units, it is difficult to respond effectively in real time to multi-physical field coupled disturbances during transportation.

[0003] However, existing cold chain transport warehouses for agricultural products have inherent functional architectural flaws: their temperature control system, humidification system, and shock absorption structure are independent modules, lacking a unified perception-decision-execution linkage mechanism. Traditional cold storage warehouses typically use roof evaporators for overall hysteresis cooling or heating, supplemented by simple ultrasonic atomizing devices for fixed-frequency humidification. This environmental control cannot respond to changes in the microclimate of the cargo core. Furthermore, the buffering mechanism often uses fixed-stiffness springs or rubber pads at the bottom of the warehouse, which can only passively isolate vibrations in specific frequency bands. Their damping characteristics are fixed and cannot adaptively adjust to road excitation or cargo conditions. More importantly, the two systems are completely disconnected in their operational logic. The temperature and humidity control loop and the mechanical shock absorption loop do not communicate with each other and operate independently, lacking a collaborative compensation strategy based on real-time operating conditions. This makes the transport warehouse essentially just a physical superposition of an insulated box and a shock-absorbing base, rather than an intelligent carrier with global optimization capabilities.

[0004] Specifically, this technology exposes significant failure risks under extreme conditions. When vehicles pass over potholes or speed bumps and experience severe impacts, fresh fruits on the shelves suffer microscopic tissue damage due to inertial compression. Once the wounds are exposed, they quickly induce dehydration, oxidation, respiratory bursts, and microbial infection. Existing equipment can only passively absorb some kinetic energy through elastic elements and cannot simultaneously activate the emergency environment of sudden drop in temperature and humidity saturation inside the warehouse to suppress the cascading amplification of damage. Conversely, when the refrigeration system fails or the temperature and humidity inside the warehouse become unbalanced due to high temperatures, the flesh of fruits and vegetables softens and the skin becomes brittle due to dehydration. Their inherent impact resistance threshold drops significantly, but the damping stiffness of the shock absorption mechanism cannot be dynamically increased. Even slight bumps on normal roads can cause large-area bruising and damage due to a surge in the resonance amplitude of the goods. The aforementioned pain points fully reveal that cold chain transportation of agricultural products can no longer rely solely on the local optimization of a single physical field. It is urgent to break through the technical barriers of joint control of temperature, humidity and vibration, and develop an intelligent transportation warehouse with multi-source sensor fusion, adaptive decision-making under working conditions and coordinated linkage of actuators, so as to achieve a leap in quality assurance. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent agricultural product transport warehouse with combined temperature, humidity and vibration regulation functions, in order to solve the technical problem that the temperature control, humidification and vibration reduction systems in existing cold chain transport warehouses are independent and cannot be coordinated and regulated according to real-time operating conditions, which makes fresh agricultural products susceptible to damage and spoilage due to vibration impact and abnormal environment during transportation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A smart agricultural product transport warehouse with combined temperature, humidity, and vibration regulation functions includes an insulated warehouse body. A mounting base is fixedly installed at the bottom of the insulated warehouse body, and a multi-layer rack is installed above the mounting base. Each rack has four sets of support components at its four corners, each set including an electro-hydraulic damper and a spring fitted around it. A damping adjustment motor is installed on the side wall of each electro-hydraulic damper. A temperature control mechanism is located at the top of the insulated warehouse body, and a humidity control mechanism is installed inside the warehouse. The transport warehouse also includes an intelligent controller, which is electrically connected to the temperature control mechanism, the humidity control mechanism, and the damping adjustment motor. This invention, by setting up a multi-layer rack and installing support components composed of electro-hydraulic dampers and springs at the four corners of each rack's bottom, with a damping adjustment motor installed on the side wall of each damper, along with the temperature control mechanism at the top of the insulated warehouse body and the humidity control mechanism inside the warehouse, constructs a hardware infrastructure for three major functional modules: vibration reduction, temperature regulation, and humidification. More importantly, by setting up intelligent controllers that are electrically connected to the temperature control mechanism, humidity control mechanism and damping adjustment motor respectively, centralized control of the three types of actuators is realized for the first time at the physical level. This provides the necessary hardware prerequisite for subsequent multi-source data fusion and linkage regulation, and breaks the isolated layout defect of the temperature control, humidification and shock absorption mechanisms in traditional equipment.

[0007] Preferably, a triaxial vibration sensor is installed at the bottom of each layer of the racking system. The triaxial vibration sensor is electrically connected to the intelligent controller and is used to collect real-time vibration acceleration data in the X, Y, and Z directions experienced by each layer of the racking system during vehicle transportation, and upload the vibration acceleration data to the intelligent controller. This solution, by installing a triaxial vibration sensor at the bottom of each layer of the racking system and electrically connecting the sensor to the intelligent controller, achieves independent, real-time collection and uploading of vibration acceleration data in the X, Y, and Z directions for each layer of the racking system. This layered distributed vibration sensing layout can accurately reflect the actual stress state of the goods on each layer, overcoming the monitoring blind spots and data inaccuracies caused by traditional single-location vibration sensor installations. It provides precise vibration excitation input to the intelligent controller, thereby supporting the accurate execution of subsequent layer-by-layer differentiated vibration reduction decisions.

[0008] Preferably, temperature and humidity sensors are arranged in the corresponding area of ​​each shelf layer. These sensors are electrically connected to the intelligent controller and are used to monitor the temperature and relative humidity values ​​of the local area of ​​each shelf layer in real time, and upload these values ​​to the intelligent controller. By arranging temperature and humidity sensors in the corresponding area of ​​each shelf layer and electrically connecting them to the intelligent controller, independent and real-time monitoring and uploading of temperature and relative humidity values ​​of the local area of ​​each shelf layer is achieved. This layout can accurately capture the vertical temperature stratification and humidity segregation phenomena caused by differences in cold air delivery paths, uneven cargo stacking density, and different heat source distributions within the warehouse. This provides the intelligent controller with high spatial resolution temperature and humidity field distribution data, thereby supporting subsequent precise control of independent temperature and humidity adjustment for each layer.

[0009] Preferably, the intelligent controller has a built-in data fusion processing module and a working condition discrimination logic. The data fusion processing module is used to receive vibration acceleration data uploaded by the triaxial vibration sensor and temperature and relative humidity values ​​uploaded by the temperature and humidity sensor. The working condition discrimination logic is used to simultaneously generate vibration reduction enhancement command, cooling command and humidification command when it is determined that the current vibration acceleration exceeds the preset vibration threshold, and send them to the damping adjustment motor, the temperature control mechanism and the humidity control mechanism respectively, so as to realize the three-in-one linkage of vibration buffering, temperature regulation and humidity regulation. This solution achieves multi-source information fusion analysis of vibration acceleration data and temperature and humidity data by integrating a data fusion processing module and operating condition discrimination logic into the intelligent controller. When the intelligent controller determines that the current vibration acceleration exceeds the preset vibration threshold, it can simultaneously generate three types of commands: vibration reduction enhancement, cooling, and humidification, and send them to the damping adjustment motor, temperature control mechanism, and humidity control mechanism, respectively. This allows for a three-in-one linkage response of mechanical buffering, environmental cooling, and humidity compensation at the moment of vibration impact. This collaborative control mechanism can use the low temperature and high humidity environment to instantly repair and suppress minor damage to agricultural products, reducing bump damage simultaneously from both physical vibration reduction and biochemical protection dimensions. This ends the technical limitations of traditional equipment where each system operates independently and passively compensates after the fact.

[0010] Preferably, the temperature control mechanism includes an outdoor unit and a circulation pipe. The outdoor unit is fixedly installed on the top of the insulated warehouse, and its output end is connected to the circulation pipe. The circulation pipe is divided into multiple branch pipes, each corresponding to one layer of the racking system. Each branch pipe has an air outlet on its side facing the racking system. Multiple air outlets are spaced apart along the length of each branch pipe, used to independently deliver cold or hot air to each racking system layer by layer. This invention, by dividing the circulation pipe of the temperature control mechanism into multiple branch pipes, each corresponding to one racking system layer, and opening multiple air outlets spaced apart along the length of each branch pipe on its side facing the racking system, achieves independent layered delivery and uniform distribution of cold or hot air. This multi-layered air supply structure allows the temperature-controlled airflow prepared by the outdoor unit to be accurately delivered to each racking system layer, effectively improving the structural defects of uneven heating and cooling between upper and lower layers and excessive local temperature differences caused by single-outlet air supply in traditional cold storage warehouses, thus enhancing the uniformity and stability of the temperature field within the warehouse.

[0011] Preferably, each of the branch pipes is equipped with an independent electrically controlled regulating valve, and each of the independent electrically controlled regulating valves is electrically connected to the intelligent controller. The intelligent controller independently controls the opening degree of the independent electrically controlled regulating valve on the corresponding branch pipe of each layer based on the real-time temperature and humidity data fed back by the temperature and humidity sensors of each layer, so as to achieve independent temperature and humidity regulation of each layer of the shelf area. This solution, by setting an independent electrically controlled regulating valve on each branch pipe and electrically connecting each independent electrically controlled regulating valve to the intelligent controller, enables the intelligent controller to independently control the opening degree of the independent electrically controlled regulating valve on each branch pipe based on the real-time temperature and humidity data fed back by the temperature and humidity sensors of each layer. This layered independent regulation mechanism can implement differentiated temperature and humidity compensation on demand according to the differences in the types, stacking densities, and real-time status of agricultural products on different layers of shelves, avoiding the overcooling or overheating treatment in the traditional uniform air supply mode, and improving energy utilization efficiency and preservation quality control accuracy.

[0012] Preferably, the humidity control mechanism includes a water tank and a water pump. The water tank is fixed to the top of the inner side of the insulated chamber, and the bottom of the water tank is connected to a main pipe. The water pump is installed on the main pipe. Several atomizing nozzles are evenly mounted on the main pipe, and the spray direction of the atomizing nozzles is set towards the areas of the respective shelves. A water inlet is provided on the top of the water tank. This solution achieves layered and uniform micro-mist humidification coverage inside the chamber by fixing the water tank to the top of the inner side of the insulated chamber and connecting the water pump and several evenly mounted atomizing nozzles through the main pipe, so that the spray direction of the atomizing nozzles is set towards the areas of the respective shelves. This top-supplying and layered atomization layout design can effectively avoid the problems of uneven water mist distribution and delayed humidification in remote areas in traditional bottom or single-point humidification methods. At the same time, the active pressurization of the water pump ensures that the atomized particle size of each atomizing nozzle is uniform, providing rapid and balanced relative humidity compensation inside the chamber. It is especially suitable for emergency scenarios where a high-humidity repair environment needs to be created immediately after vibration damage.

[0013] Preferably, a lighting lamp is installed on the top inner side of the insulated compartment, and a sealing gasket is fixedly installed at the edge of the compartment opening. The sealing gasket is continuously arranged circumferentially along the edge of the compartment opening, and the cross-section of the sealing gasket is rectangular or trapezoidal. This invention provides sufficient lighting for loading, unloading, inspection, and maintenance of goods inside the compartment by installing a lighting lamp on the top inner side of the insulated compartment. Simultaneously, by setting a continuously arranged rectangular or trapezoidal sealing gasket at the edge of the compartment opening, the airtightness of the compartment opening is enhanced when the sealed door is closed. The trapezoidal cross-section design has better compressibility than the traditional rectangular cross-section, generating a larger contact area and sealing pressure when the sealed door is pressed together, reducing heat and moisture exchange between the inside and outside of the compartment, reducing cold loss and humidity dissipation, thereby reducing the load on the temperature and humidity control mechanism and improving overall energy efficiency.

[0014] Preferably, the insulated compartment opening is hinged with a sealing door, and an operating handle is fixedly mounted on the outer wall of the sealing door. The inner side wall of the sealing door is provided with a sealing protrusion that corresponds to and abuts against the sealing gasket, used to compress the sealing gasket and form an airtight seal when the sealing door is closed. This invention provides a convenient opening and closing experience by hinged to a sealing door at the insulated compartment opening and mounting an operating handle on the outer wall of the sealing door. Simultaneously, by providing a sealing protrusion on the inner side wall of the sealing door that corresponds to and abuts against the sealing gasket, the sealing protrusion can compress the sealing gasket and form an airtight seal when the sealing door is closed. This dual-sealing structure design, through the combined effect of the elastic deformation of the sealing gasket and the rigid compression of the sealing protrusion, improves the airtightness of the compartment opening sealing interface, resisting the instantaneous impact disturbance to the compartment door's seal caused by road bumps during transportation, and ensuring the long-term stability of the microenvironment inside the compartment.

[0015] Preferably, a control cabinet can be detachably installed on the outside of the sealed door, and the intelligent controller is integrated inside the control cabinet. A touch display panel is embedded in the outer wall of the control cabinet, and the touch display panel is electrically connected to the intelligent controller. This panel is used to display the vibration, temperature, and humidity data of each layer of the shelving in real time, and allows operators to input set parameters and manually switch working modes. This solution achieves a compact layout and convenient maintenance of the core control module by integrating the intelligent controller into the control cabinet that is detachably mounted on the outside of the sealed door. The touch display panel embedded in the outer wall of the control cabinet, electrically connected to the intelligent controller, enables real-time visualization of the vibration, temperature, and humidity data of each layer of the shelving. It also provides operators with the ability to input set parameters and manually switch working modes. This design makes the control status of the transport warehouse clear at a glance, facilitating quick viewing of the environmental parameters of goods on each layer during transport, and allowing for flexible adjustment of target control parameters based on the different types of goods actually loaded, thus improving the equipment's ease of operation and adaptability to various scenarios.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The integrated intelligent control architecture constructed in this invention breaks through the traditional technical pattern of separating temperature and humidity management from vibration buffering in cold chain transportation warehouses. By deploying triaxial vibration sensors and a distributed temperature and humidity sensor network, the system can capture multi-dimensional physical quantities such as road bump impact loads, temperature field gradient changes within the warehouse, and humidity fluctuations in real time, and unify heterogeneous data into an intelligent controller for fusion analysis. The core value of this collaborative mechanism lies in its ability to inhibit respiratory jumps and impede transpiration water loss at the moment microscopic wounds appear on the surface of fruits and vegetables, thereby sealing the oxidation channels of the wounds and slowing down the rate of microbial infection. It converts vibration mechanical energy into environmental regulation potential energy, ending the technical predicament of traditional equipment where each subsystem operates independently and responds passively after the fact.

[0017] 2. This invention has made systematic optimizations in terms of environmental uniformity and proactive prediction and protection. In response to the common problems of vertical temperature stratification and humidity segregation in traditional cold storage warehouses, this invention adopts a multi-layer air supply pipeline and independent air duct regulating valves, so that the cold air after precise temperature and humidity adjustment can be distributed to each layer of the shelf area as needed, forming independent yet coordinated layer microclimate units. This ensures that the temperature and humidity uniformity at any location in the warehouse can be kept stable within the target preservation range, eliminating the structural defects of overheating in the upper layer and undercooling in the lower layer in conventional equipment. More importantly, this intelligent system does not only react to the impact that has already occurred, but also introduces a feedforward predictive logic based on the trend of environmental degradation: when the temperature and humidity sensors continuously detect that the temperature and humidity in the warehouse are drifting in the direction of deterioration and deviating from the optimal storage parameters for fruits and vegetables, the controller will automatically determine that the environmental change will lead to softening of the flesh, dehydration and brittleness of the skin, and a decrease in the inherent impact resistance threshold. Then, before the vibration impact is applied, it actively instructs the damping adjustment motor to increase the damping preset value of the shock absorption mechanism in advance, and switches the suspension system to a high-stiffness anti-vibration mode. In this way, a buffer barrier is built before the vibration excitation reaches the goods, avoiding the inherent defects of traditional passive shock absorbers in response to variable amplitude loads with lag and insufficient protection time.

[0018] 3. This invention constructs a closed-loop protection system covering pre-vibration adjustment, in-vibration coordination, and post-vibration repair through a dual strategy of real-time linkage response and proactive predictive protection. In the pre-vibration stage, the system pre-sets damping parameters based on temperature and humidity degradation trends to achieve preventative protection. In the in-vibration stage, mechanical vibration reduction and low-temperature, high-humidity environmental control are executed in parallel, using physical buffering to reduce peak impact and biochemical environment to inhibit damage deterioration. In the post-vibration stage, the continuous maintenance of low temperature and high humidity helps delay oxidative browning of the wound, providing a window for quality repair in subsequent circulation stages. This not only achieves deep coordination in both temperature and humidity maintenance and vibration buffering, but also endows the transport warehouse with adaptive capabilities to complex road conditions and environmental fluctuations at the control logic level.

[0021] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0022] like Figures 1-6 As shown, this invention provides an intelligent agricultural product transport warehouse with combined temperature, humidity, and vibration regulation functions. It includes an insulated warehouse body 1, with a mounting base 2 fixedly installed at the bottom inner side. A multi-layer rack 6 is mounted above the mounting base 2. Each rack 6 has four sets of support components at its four corners. Each support component includes an electro-hydraulic damper 3 and a spring 4 fitted onto the outside of the damper 3. A damping adjustment motor 5 is installed on the side wall of each damper 3. Through this multi-point independent support layout, each rack 6 obtains independent buffering and shock absorption capabilities, providing differentiated damping support for the quality differences and stacking conditions of goods at different levels. The insulated warehouse body 1 has a temperature control mechanism 8 at the top and a humidity control mechanism 9 inside. The transport warehouse also has an intelligent controller, which is electrically connected to the temperature control mechanism 8, the humidity control mechanism 9, and the damping adjustment motor 5. This creates a unified architecture at the hardware level where shock absorption, temperature regulation, and humidification are centrally controlled, providing a foundation for subsequent multi-source information fusion and collaborative control.

[0023] Each layer of the shelving unit 6 is equipped with a triaxial vibration sensor 7 at its bottom. These sensors are electrically connected to the intelligent controller and are used to collect real-time vibration acceleration data in the X, Y, and Z directions experienced by each layer of shelving unit 6 during vehicle transportation, uploading the vibration acceleration data to the intelligent controller. A temperature and humidity sensor 10 is also arranged in the corresponding area of ​​each layer of shelving unit 6. These sensors are electrically connected to the intelligent controller and are used to monitor the local temperature and relative humidity values ​​of each layer of shelving unit 6 in real-time, uploading these values ​​to the intelligent controller. This layered distributed sensing layout can accurately capture the actual stress state and microclimate parameters of the goods on each layer, overcoming the monitoring blind spots and data inaccuracies caused by traditional single-location sensor installations, and providing the intelligent controller with high spatial resolution vibration and temperature / humidity field distribution information. The intelligent controller incorporates a data fusion processing module and operating condition discrimination logic. The data fusion processing module receives vibration acceleration data uploaded by the triaxial vibration sensor 7 and temperature and relative humidity values ​​uploaded by the temperature and humidity sensor 10. The operating condition discrimination logic, when determining that the current vibration acceleration exceeds a preset vibration threshold, simultaneously generates vibration reduction enhancement commands, cooling commands, and humidification commands, which are then sent to the damping adjustment motor 5, the temperature control mechanism 8, and the humidity control mechanism 9, respectively, achieving a three-in-one linkage of vibration buffering, temperature regulation, and humidity regulation. This collaborative control mechanism can complete the parallel execution of mechanical buffering, environmental cooling, and humidity compensation the instant vibration impact occurs, simultaneously reducing bump losses from both physical vibration reduction and biochemical protection dimensions, ending the technical limitations of traditional equipment where each system operates independently and passively compensates afterward.

[0024] The temperature control mechanism 8 includes an outdoor unit 801 and a circulation pipe 802. The outdoor unit 801 is fixedly installed on the top of the insulated compartment 1, and its output end is connected to the circulation pipe 802. The circulation pipe 802 is divided into multiple branch pipes 803, each branch pipe 803 corresponding to a layer of racks 6. Each branch pipe 803 has an air outlet 804 on its side facing the rack 6. Multiple air outlets 804 are arranged at intervals along the length of the branch pipe 803, used to independently deliver cold or hot air to each layer of rack 6. This multi-layer air supply structure enables the temperature-controlled airflow prepared by the outdoor unit 801 to be accurately delivered to each layer of rack 6, improving the structural defects of uneven heating and cooling and excessive local temperature differences caused by single air outlets in traditional cold storage. Each branch pipe 803 is equipped with an independent electrically controlled regulating valve, which is electrically connected to the intelligent controller. Based on real-time temperature and humidity data fed back by the temperature and humidity sensors 10 on each layer, the intelligent controller independently controls the opening of the independent electrically controlled regulating valve on the corresponding branch pipe 803 for each layer, thereby achieving independent and precise adjustment of the temperature and humidity in each shelf area 6. This layered independent adjustment mechanism can implement differentiated temperature and humidity compensation on demand, taking into account differences in the type, stacking density, and real-time status of agricultural products on different shelves 6. This avoids overcooling or overheating in the traditional uniform air supply mode, improving energy efficiency and the accuracy of preservation quality control.

[0025] The humidity control mechanism 9 includes a water tank 901 and a water pump 902. The water tank 901 is fixed to the top of the inner side of the insulated chamber 1. The bottom of the water tank 901 is connected to a main pipe 903, and the water pump 902 is installed on the main pipe 903. Several atomizing nozzles 904 are evenly mounted on the main pipe 903, and the spray direction of the atomizing nozzles 904 is set towards the area of ​​each layer of the rack 6. A water inlet 905 is opened on the top of the water tank 901. This top-supplying, layered atomization layout design can avoid the problems of uneven water mist distribution and delayed humidification in remote areas in traditional bottom or single-point humidification methods. The water pump 902 actively pressurizes to ensure that the atomized particle size of each atomizing nozzle 904 is uniform, providing rapid and balanced relative humidity compensation in the chamber. It is especially suitable for emergency scenarios where a high-humidity repair environment needs to be created immediately after vibration damage.

[0026] A lighting lamp 11 is installed on the top inner side of the insulated compartment 1 to provide sufficient lighting for loading, unloading, inspection, and maintenance of goods inside the compartment. A sealing gasket 12 is fixedly installed at the edge of the compartment opening of the insulated compartment 1. The sealing gasket 12 is continuously arranged circumferentially along the edge of the compartment opening of the insulated compartment 1, and the cross-section of the sealing gasket 12 is rectangular or trapezoidal. A sealing door 13 is hinged to the compartment opening of the insulated compartment 1. An operating handle 15 is fixedly installed on the outer wall of the sealing door 13. A sealing protrusion is provided circumferentially on the inner side wall of the sealing door 13, which is used to compress the sealing gasket 12 and form an airtight seal when the sealing door 13 is closed. This double sealing structure design, under the combined action of the elastic deformation of the sealing gasket 12 and the rigid pressing of the sealing protrusion, improves the airtightness of the compartment opening interface, effectively resists the instantaneous impact disturbance of road bumps on the compartment door seal during transportation, reduces heat and moisture exchange between the inside and outside of the compartment, reduces cold loss and humidity dissipation, and ensures the long-term stability of the microenvironment inside the compartment. A control cabinet 14 can be detachably installed on the outside of the sealed door 13, with the intelligent controller integrated inside. A touch-screen display panel is embedded in the outer wall of the control cabinet 14. This panel is electrically connected to the intelligent controller and displays real-time vibration, temperature, and humidity data for each layer of the shelving unit 6. It also allows operators to input setting parameters and manually switch operating modes. This human-machine interface provides a clear overview of the control status of the transport warehouse, facilitating quick viewing of environmental parameters for goods on each layer during transport and allowing for flexible adjustment of target control parameters based on the specific types of goods being loaded. This enhances the equipment's ease of operation and adaptability to various scenarios.

[0027] In this invention, the intelligent controller is a programmable logic controller, a mature and standardized product widely used in the field of industrial control, preferably the Siemens S7-1200 series, specifically the CPU 1214C. The DC / DC / DC converters mentioned above are commercially available general-purpose devices, equipped with multi-channel analog input, digital input / output, and standard communication interfaces such as RS485 and CAN. The intelligent controller is integrated and installed inside the control cabinet 14. The control cabinet 14 is a standardized electrical control cabinet with guide rails and terminal blocks inside. The intelligent controller is fixedly installed inside the control cabinet 14 by guide rail clips. The signal lines of each sensor and actuator are introduced into the control cabinet 14 through shielded cables and electrically connected to the corresponding input / output ports of the intelligent controller through the terminal blocks. The above hardware selection, wiring assembly, and cabinet layout are all mature technologies that can be completed by those skilled in the art according to conventional electrical control specifications. No creative labor other than program development or parameter tuning is required. The control program running inside the intelligent controller is written in ladder diagram or C language. Its core algorithms such as signal acquisition, threshold comparison, PID calculation, and logic judgment are all well-known technologies in the field of automation control and have a long-term and extensive application foundation in various equipment such as cold chain transportation, environmental test chambers, and vibration control consoles. The control cabinet 14 is detachably installed on the reserved mounting position on the outer wall of the sealed door 13 by bolts. Its front panel is equipped with a touch-screen human-machine interface or indicator lights and button panel, which allows operators to view operating parameters such as temperature, humidity and vibration in real time, as well as manually set and adjust control parameters such as temperature setpoint, humidity setpoint and vibration threshold.

[0028] The working principle of this invention is as follows: After the invention is activated, the triaxial vibration sensor 7 installed at the bottom of each shelf 6 collects the vibration acceleration signals of each shelf 6 in the X, Y, and Z axes in real time. The temperature and humidity sensor 10 arranged in the corresponding area of ​​each shelf 6 collects the temperature and relative humidity data of each area in real time. The signals collected by each sensor are transmitted in real time to the intelligent controller integrated inside the control cabinet 14 via signal lines. The intelligent controller has preset vibration acceleration thresholds and temperature and humidity preservation standard ranges adapted to different types of agricultural products. These standard ranges can be flexibly set through the touch display panel on the control cabinet 14 according to the different types of goods loaded. When the vehicle is traveling on a smooth road surface, the vibration acceleration amplitude detected by the triaxial vibration sensor 7 is below the preset threshold. The intelligent controller determines that the current transportation condition is within a safe range and does not send an active adjustment command. The electro-hydraulic damper 3 maintains a basic damping state, and the static weight of the rack 6 and the goods is borne by the spring 4 sleeved on its outside and provides basic buffering. The temperature control mechanism 8 and the humidity control mechanism 9 only perform normal range maintenance operation based on the feedback of the temperature and humidity sensor 10, and the transportation warehouse is in a normal insulated transportation mode.

[0029] When a vehicle experiences severe bumps and jolts while traveling over potholes, speed bumps, or sharp bends and steep slopes, the vibration acceleration amplitude detected by the triaxial vibration sensor 7 exceeds a preset threshold. The intelligent controller's built-in condition judgment logic immediately triggers a linkage response mechanism. The intelligent controller first sends a vibration reduction enhancement command to the damping adjustment motor 5. Upon receiving the command, the damping adjustment motor 5 rotates forward, and its output drives the regulating valve core inside the electro-hydraulic damper 3 to rotate, reducing the hydraulic oil circuit flow cross-sectional area. This causes a step increase in the damping force of the electro-hydraulic damper 3. The increased damping force, combined with the elastic restoring force of the spring 4, forms a high-energy-consuming buffer circuit the instant the vibration excitation is input, rapidly dissipating vibration energy and causing the vibration amplitude of the rack 6 to decay to a safe range in a shorter time. This suppresses secondary collisions and resonance amplification effects between the goods and the rack. Simultaneously, at the same time as issuing the vibration reduction enhancement command, the intelligent controller sends a cooling command to the temperature control mechanism 8 and a humidification command to the humidity control mechanism 9. All three are executed synchronously without any time lag. The outdoor unit 801 of the temperature control mechanism 8 starts the refrigeration cycle, and after the refrigerant is compressed and expanded, it is delivered to the circulation pipe 802. The refrigerant is diverted from the circulation pipe 802 into the branch pipes 803 of each layer. The cold air is blown downward evenly from the air outlet 804 opened on one side of the shelf 6 from the branch pipe 803, so that the temperature of each shelf 6 area is quickly reduced to near the lower limit of the preservation zone. The water pump 902 of the humidity control mechanism 9 starts running at the same time, pressurizing the clean water in the water tank 901 and pumping it to the main pipe 903. Then, the atomizing nozzles 904 evenly assembled on the main pipe 903 atomize the high-pressure water flow into fine water mist particles with uniform particle size. The water mist diffuses from top to bottom to each layer of the space in the warehouse, so that the relative humidity in the warehouse is quickly increased to near saturation. Through the aforementioned linkage control, the intelligent controller simultaneously activates the collaborative protection mode at the same moment the vibration and impact occur. It utilizes the synergistic biochemical effects of low temperature inhibiting respiratory jump and enzymatic oxidation reaction, and high humidity inhibiting epidermal transpiration and water loss and wound drying and cracking to instantly repair and inhibit minor wounds caused by bumps and knocks on agricultural products. It effectively seals the oxidation channels of the wound and slows down the rate of microbial infection, thereby systematically reducing fresh food loss from two dimensions: mechanical buffering and environmental compensation.

[0030] When the temperature and humidity sensor 10 detects that the temperature and humidity of a certain layer or the entire warehouse deviates from the preset preservation standard range, the intelligent controller determines that this environmental degradation trend will lead to softening of the fruit flesh, dehydration and brittleness of the skin, and a decrease in cell turgor pressure, thereby reducing the inherent shock resistance of the goods. In this case, the intelligent controller no longer waits for the actual vibration and impact to occur, but actively sends a pre-adjustment command to the damping adjustment motor 5 based on the temperature and humidity deviation trend. The damping adjustment motor 5 drives the adjustment valve core to rotate, raising the damping force of the electro-hydraulic damper 3 to the preparatory protection level in advance, so that the shock absorption mechanism is in a high-damping standby state before the subsequent possible vibration and impact arrives, achieving proactive protection before problems occur. Subsequently, the intelligent controller sends an environmental correction command to the temperature control mechanism 8 and the humidity control mechanism 9. The temperature control mechanism 8 starts the cooling or heating mode according to the direction of the deviation, and accurately delivers the temperature-regulating airflow to the corresponding deviation area through the layered pipes 803, gradually correcting the temperature back to the preservation standard range; the humidity control mechanism 9 simultaneously starts the humidification mode, and replenishes water mist into the warehouse through the atomizing nozzles 904, correcting the relative humidity back to the preservation standard range. When the temperature and humidity sensor 10 detects that the temperature and humidity data have returned to the standard range for freshness preservation and remain stable, the intelligent controller sends a damping recovery command to the damping adjustment motor 5 to restore the damping force of the electro-hydraulic damper 3 to the normal operating level, so as to avoid unnecessary energy consumption and component wear caused by excessive damping on smooth road sections.

[0031] Throughout the transportation process, the triaxial vibration sensor 7 and the temperature and humidity sensor 10 maintain continuous real-time monitoring. Sampling data is continuously uploaded to the intelligent controller at millisecond intervals. The intelligent controller's built-in data fusion processing module dynamically fuses and analyzes the multi-source sensor information. Based on the changing trends of real-time road conditions and environmental parameters, it continuously iterates and executes corresponding linkage adjustment strategies, ensuring that the temperature control mechanism 8, humidity control mechanism 9, and electro-hydraulic damper 3 are always in an adaptive and coordinated working state, achieving dynamic joint control of temperature and humidity regulation and shock absorption. During this process, the sealing gasket 12 is pressed between the door and the compartment opening when the sealing door 13 is closed. Its trapezoidal or rectangular cross-section, under compression deformation, forms a multiple sealing interface with the sealing strip, maintaining the airtightness of the compartment and effectively preventing the leakage of cold air and moisture, thus reducing energy loss. The lighting 11 is turned on during cargo loading and unloading and warehouse inspection to provide operators with sufficient light to observe the cargo status. Operators can open or close the sealing door 13 by operating the handle 15, and view real-time parameters, adjust preset thresholds, and perform manual emergency operations through the touch display panel embedded in the outer wall of the control cabinet 14, ensuring that the transport warehouse has good interactive flexibility and scenario adaptability between automatic intelligent control and manual intervention.

[0032] In summary, this invention utilizes an adjustable shock absorption system comprised of an insulated storage unit, multi-layer shelving, an electro-hydraulic damper, springs, and a damping adjustment motor. This system, combined with a temperature control mechanism, a humidity control mechanism, a triaxial vibration sensor, a temperature and humidity sensor, and an intelligent controller, achieves integrated regulation of temperature and humidity control and vibration buffering. When vibration exceeds the limit, the controller simultaneously increases damping and initiates cooling and humidification to repair damage to agricultural products caused by impacts in a low-temperature, high-humidity environment. When the temperature and humidity deviate from the preservation range, the controller proactively increases the damping force to actively protect against impending vibration impacts. The coordinated action of all components ensures the transportation quality of fresh agricultural products from both environmental compensation and shock absorption perspectives. The system is compact and offers timely control and response.
