Description

Technical Field

[0001] This invention relates to the field of temperature and humidity control technology, specifically to a method and system for controlling a constant temperature and humidity environment in cultural and tourism scenarios. Background Technology

[0002] In cultural and tourism settings, the display of cultural relics and the storage of specialty products require extremely high temperature and humidity stability, necessitating the continuous maintenance of specific temperature and humidity environments. Existing conventional refrigeration and temperature and humidity control equipment is mostly designed for open spaces, making it difficult to achieve precise constant temperature and humidity control for small, localized spaces, and is easily affected by fluctuations in the external environment.

[0003] Although some existing devices have basic temperature and humidity regulation functions, their sensing and detection methods are relatively limited. They also lack precise control based on airflow circulation paths, which can easily lead to local deviations, and there is a certain degree of lag in parameter adjustment response.

[0004] Therefore, there is an urgent need for an efficient temperature and humidity control solution that is suitable for cultural and tourism scenarios, so as to meet the needs of flexible, accurate and stable constant temperature and humidity control in cultural and tourism scenarios. Summary of the Invention

[0005] This application provides a method and system for controlling constant temperature and humidity in cultural and tourism scenarios, which addresses the technical problem that existing technologies cannot meet the flexible, accurate and stable constant temperature and humidity control requirements in cultural and tourism scenarios.

[0006] In view of the above problems, this application provides a method and system for controlling constant temperature and humidity environment in cultural and tourism scenarios.

[0007] In a first aspect, this application provides a method for controlling a constant temperature and humidity environment in a cultural and tourism setting. The method includes: deploying a constant temperature and humidity automatic terminal in the cultural and tourism venue and routing it into the network, setting pre-controlled temperature and humidity conditions; writing the temperature and humidity conditions into a first register, establishing a flow field loop with a first sensor group-air duct-second sensor group, introducing a logic drive circuit based on the relative correction principle, and configuring the unit controller; updating the flow field loop by executing dual-sided temperature and humidity sensing based on the first sensor group and the second sensor group, assisting the logic drive circuit to reverse-engineer the unit parameters for temperature and humidity control based on the correction of the flow field loop, writing them into a second register, and executing the parameter control drive management of the temperature and humidity regulating unit. The control dimension includes a first relative adjustment based on relative temperature and humidity, and a second relative compensation based on relative signal time delay.

[0008] Secondly, this application provides a constant temperature and humidity environment control system for cultural and tourism scenarios. The system includes: a condition setting unit, used to deploy constant temperature and humidity automatic terminals in cultural and tourism venues and route them into the network, and set pre-controlled temperature and humidity conditions; a controller configuration unit, used to write the temperature and humidity conditions into a first register, establish a flow field loop with a first sensor group-air duct-second sensor group, introduce a logic drive circuit based on the relative correction principle, and configure the unit controller; and an adjustment drive unit, used to update the flow field loop by executing dual-sided temperature and humidity sensing based on the first sensor group and the second sensor group, assist the logic drive circuit in back-deriving the unit parameters for temperature and humidity regulation based on the correction of the flow field loop, write them into a second register, and execute the parameter control drive management of the temperature and humidity regulating unit. The regulation dimension includes a first relative adjustment based on relative temperature and humidity and a second relative compensation based on relative signal time delay.

[0009] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0010] This application provides a method for controlling constant temperature and humidity in cultural and tourism scenarios. It involves deploying automatic temperature and humidity terminals in cultural and tourism venues and routing them into the network, setting pre-controlled temperature and humidity conditions. These conditions are written into a first register. A flow field loop is established using a first sensor group, an air duct, and a second sensor group. A logic drive circuit based on the relative correction principle is introduced to configure the unit controller. By executing dual-sided temperature and humidity sensing based on the first and second sensor groups, the flow field loop is updated. This assists the logic drive circuit in using the corrections from the flow field loop to inversely deduce the unit parameters for temperature and humidity control, which are then written into a second register.

[0015] This application provides a method and system for controlling constant temperature and humidity in cultural and tourism scenarios, which solves the technical problem in the prior art that makes it difficult to meet the needs of flexible, accurate and stable constant temperature and humidity control in cultural and tourism scenarios.

[0016] Example 1: As Figure 1 , Figure 2 As shown, this application provides a method for controlling a constant temperature and humidity environment in a cultural and tourism setting, the method comprising:

[0017] S1: Deploy constant temperature and humidity automatic terminal units in cultural and tourism venues and route them into the network, setting pre-controlled temperature and humidity conditions.

[0018] In this embodiment, a constant temperature and humidity intelligent self-service terminal is deployed in a cultural and tourism venue, based on the actual application requirements, at a suitable installation location. The constant temperature and humidity intelligent self-service terminal is a device that performs constant temperature and humidity control, and its main components include: a temperature and humidity regulating unit, a unit controller, an air duct, and a main control module.

[0019] Specifically, the temperature and humidity control unit is a drive component that regulates the temperature and humidity of the air inside the equipment enclosure. The air outlet duct delivers the regulated air through the unit, and its function is to guide the airflow in the desired direction, directing it upwards towards the enclosure. The unit controller controls the operating parameters of the temperature and humidity control unit, including the start and stop parameters for the temperature and humidity control components. The main control module is the master controller for the entire equipment. Besides controlling the motion logic of the mechanical parts within the unit, it also monitors and sets the temperature and humidity within the equipment. This application primarily focuses on managing the temperature and humidity control functions.

[0020] After the equipment is deployed, it connects to the network via the router provided with the equipment, enabling communication between the equipment and the management backend, thus ensuring the ability to remotely view the equipment status and remotely set temperature and humidity conditions.

[0021] Next, the pre-controlled temperature and humidity conditions are set. This can be done in two ways: First, the operator operates on the local control panel, inputting the target temperature and humidity values ​​required by the cultural and tourism venue. For example, if a cultural relic display scene needs to be set to 20℃ and 50% humidity, the local control panel will transmit the set values ​​to the unit controller. Second, the setting is done remotely through the management backend. The setting command is transmitted to the main control module via the router, and then the main control module sends it to the unit controller.

[0022] Furthermore, step S1 of this application includes: the constant temperature and humidity automatic terminal includes a temperature and humidity regulating unit, a unit controller, an air duct, and a main control module; wherein, the main control module is connected to a first sensor group, the unit controller is connected to the main control module and a second sensor group, wherein the first sensor group is installed inside the housing, and the second sensor group is installed at the return air inlet of the air duct.

[0023] In this embodiment, the key components of the constant temperature and humidity automatic terminal include a temperature and humidity regulating unit, a unit controller, an air duct, and a main control module. The specific driving functions of these components for constant temperature and humidity are as follows:

[0024] The temperature and humidity control unit is installed inside the enclosure and serves as the drive controller for regulating temperature and humidity. Specifically, the unit mainly consists of two parts: the first part regulates temperature, and the second part regulates humidity.

[0025] The unit controller is used to make drive decisions, that is, to analyze and determine the operating parameters that need to be adjusted, including the parameters of the temperature regulation section and the humidity regulation section. The specific operation mode of the equipment proposed in this application is as follows: the unit controller obtains data such as temperature and humidity values ​​at the unit's return air vent from the sensor side connected to it, and determines the start and stop logic of the temperature and humidity regulation sections through calculation.

[0026] The air duct is through which the air regulated by the temperature and humidity control unit is sent out. The function of the air duct is to limit the airflow to flow in the required direction, that is, to direct the airflow to the upper part of the box.

[0027] The main control module is the master controller of the entire equipment. In this application's technical solution, the logic analysis mainly focuses on the temperature and humidity regulation functions. Simultaneously, the main control module connects to the network via a router, enabling remote monitoring of the internal temperature and humidity of the equipment. If necessary, target temperature and humidity values ​​can be set remotely. Optionally, the main control module connects to the unit controller via a communication line, allowing the transmission of temperature and humidity commands received from the cloud to the unit controller.

[0028] The first sensor group is a sensor group for collecting temperature and humidity data inside the equipment enclosure. In specific implementation, the first sensor is connected to the main control module and transmits the temperature and humidity values ​​collected inside the enclosure to the main control module. The second sensor group is installed at the return air vent of the equipment and connected to the unit controller. It is used to collect the temperature and humidity at the return air vent and transmit the results to the unit controller.

[0029] Furthermore, the constant temperature and humidity automatic terminal machine proposed in this application also includes the following equipment components:

[0030] Specifically: Insulated box: The interior of the insulated box is a constant temperature and humidity environment, while the exterior is an uncontrollable environment. The box is made of two layers of sheet metal with high-density insulation cotton sandwiched in between, which is used to isolate heat transfer; Insulated front door: The box is equipped with an openable and closable front door, which is used to isolate the constant temperature and humidity environment from the external environment. The front door of the insulated cabinet is also made of two layers of sheet metal with high-density insulation cotton sandwiched in between; Magnetic sealing strip: The magnetic sealing strip is used to ensure that the constant temperature and humidity space inside the cabinet is completely isolated from the external environment when the front door is closed. The magnetic sealing strip has a certain degree of airtightness and blocks heat transfer between the inside and outside of the cabinet when the front door is closed; Air outlet: The air outlet is set on the air duct. After the air passes through the outlet, it continues to flow towards the top of the cabinet due to inertia and subsequent wind pressure; Return air inlet: The return air inlet of the temperature and humidity control unit. The air inside the cabinet enters the temperature and humidity control unit through the return air inlet, is processed by the unit, and is then discharged from the unit; Control panel: Enables user interaction functions. Users can use this panel to input the required temperature and humidity settings into the unit controller.

[0031] Furthermore, setting pre-controlled temperature and humidity conditions, step S1 of this application includes:

[0032] The system receives temperature and humidity standards from cultural and tourism venues, wherein the temperature and humidity standards are uploaded remotely by the main control module or locally by the control panel; by identifying the temperature and humidity standards, the system converts them into unit data dimensions as the temperature and humidity conditions, wherein the temperature and humidity conditions are the constant temperature and humidity control requirements for a period of time.

[0033] In this embodiment of the application, the temperature and humidity standards of the cultural and tourism venues are received. The temperature and humidity standards are temperature and humidity benchmarks determined in cultural and tourism scenarios to meet specific constant temperature and humidity requirements, such as avoiding dampness and mold in the display of cultural relics and maintaining a stable and dry environment for special exhibits.

[0034] In one specific acquisition method, it is based on remote upload from the main control module or local upload from the control panel.

[0035] Specifically, based on the remote upload method of the main control module, managers input temperature and humidity standards through a management backend connected to the device, which are then routed to the main control module for reception and temporary storage. For example, if a cultural tourism exhibition hall needs to maintain a temperature of 22℃ and humidity of 55% from 9:00 to 17:00 on weekdays, managers can set this standard in the backend and upload it to the main control module.

[0036] Similarly, based on the local upload method of the control panel, the operator can directly input the temperature and humidity standards on the local control panel of the equipment. As a user interaction component, the panel will directly transmit the input standards to the temperature and humidity control unit controller.

[0037] Subsequently, by identifying the temperature and humidity standards, the unit controller or main control module parses the received temperature and humidity standards to clarify the temperature values, humidity values, and related time parameters contained therein. Then, the standards are converted into unit data dimensions, that is, converted into parameter forms that the temperature and humidity regulating unit can recognize and execute. For example, in the unit's operating logic, a coding form is used, such as the coding representation parameters corresponding to cooling, heating, humidification, dehumidification, etc., and these are used as temperature and humidity conditions.

[0038] Among them, the temperature and humidity conditions refer to the constant temperature and humidity control requirements during a period of time, that is, the constant temperature control requirements and constant humidity control requirements within a control time interval. This is to facilitate adaptation to the internal mechanism of the temperature and humidity control unit and to lay a solid foundation for subsequent automated control decisions.

[0039] S2: Write the temperature and humidity conditions into the first register, establish a flow field loop with the first sensor group-air duct-second sensor group, introduce a deployment logic drive circuit based on the relative correction principle, and configure the unit controller.

[0040] In this embodiment of the application, the temperature and humidity conditions are written into the first register. The first register is a storage unit for storing the temperature and humidity control requirements for a period of time. The temperature and humidity conditions stored therein will serve as the basis for subsequent regulation. For example, the temperature and humidity standards for a certain cultural tourism and creative exhibition area for a certain period of time will be converted and written into the first register. The data will only be effective for regulation within that period of time.

[0041] Subsequently, a flow field loop is established within the internal space of the constant temperature and humidity intelligent self-service terminal machine, consisting of the first sensor group, the air duct, and the second sensor group. The first sensor group corresponds to the temperature and humidity sensor in the middle of the equipment box, used to collect the actual temperature and humidity inside the box. The air duct includes the air outlet duct and the air return vent related airflow path. That is, the air processed by the temperature and humidity regulating unit is sent to the top of the box through the air outlet duct and the air outlet, then flows from the left side of the top to the right side, descends to the right side of the bottom, and then flows to the left. The second sensor group corresponds to the unit's temperature and humidity sensor at the air return vent, used to collect the temperature and humidity of the air entering the unit.

[0042] In the specific scenario proposed in this application, the flow field loop formed by the three is essentially a temperature and humidity sensing and circulation system built based on the natural flow path of airflow. That is, the first sensor group senses the temperature and humidity in the middle of the box, and after the airflow completes circulation through the air duct, the second sensor group senses the temperature and humidity at the return air vent, thereby achieving full coverage monitoring of the temperature and humidity distribution and flow status inside the box.

[0043] In one feasible implementation of this application, a logic drive circuit based on the principle of relative correction is introduced. The deployment of this logic drive circuit is based on the temperature and humidity transmission characteristics within the enclosure: on the one hand, the temperature and humidity difference between the first and second sensor groups, i.e., the spatial relative difference proposed in this application, is used to correct the activation threshold of temperature and humidity regulation; on the other hand, based on the airflow transmission time in the duct, which in this application can refer to the time delay of airflow from the air outlet to the air return outlet, i.e., the time relative difference proposed in this application, the timing of the adjustment command execution is compensated.

[0044] For example, when the first sensor group detects that the humidity in the middle of the cabinet is slightly higher than the set value, while the second sensor group has not yet detected the corresponding change due to the airflow transmission delay, the circuit can trigger the dehumidification preparation command in advance based on the delay data.

[0045] Finally, the control logic of the above-mentioned logic drive circuit is written into the unit controller to complete the configuration of the unit controller. This enables the unit controller to perform logic-driven decision analysis based on the temperature and humidity conditions in the first register and the temperature and humidity sensing data in the flow field loop, and to accurately control the operation of the temperature and humidity regulating unit.

[0046] Furthermore, a logic drive circuit based on the principle of relative correction is introduced. Step S2 of this application includes: deploying an initialization logic circuit with a first relative adjustment and a second relative compensation, wherein the first relative adjustment is performed based on the relative temperature and humidity of the first register and the flow field loop, and the second relative compensation is the signal relative time delay of the distributed control point of temperature and humidity regulation; adaptively adjusting the initialization logic circuit according to the control mechanism of the temperature and humidity regulating unit, determining the logic drive circuit and writing it into the microcontroller; and connecting the microcontroller to the unit controller.

[0047] In this embodiment, the initialization logic circuit is deployed with a first relative adjustment and a second relative compensation. The first relative adjustment is based on the relative difference between the temperature and humidity conditions stored in the first register and the temperature and humidity data collected in real time in the flow field loop. That is, the temperature and humidity adjustment trigger and adjustment amount decision are made by measuring the relative difference.

[0048] For example, the first register stores the standard temperature of 22±1℃ from 10:00 to 16:00 every day. The flow field loop detects the current temperature of 23.5℃, and the two form a relative difference of 1.5℃. The initialization logic circuit uses this difference as the basis for adjusting the intensity.

[0049] Similarly, the second relative compensation addresses the relative time delay of signals at the distributed control points of temperature and humidity regulation. Specifically, there is a physical time delay in the process of airflow traveling from the air outlet through the duct to the return air outlet. For example, this time delay has been tested to be 15 seconds. When the acquisition signal of the second sensor group lags behind that of the first sensor group, the circuit uses this time delay as a parameter to compensate for the triggering time of the regulation command, thus avoiding regulation lag due to signal lag. Based on the above logic, the initialization logic circuit is deployed.

[0050] In this application, the control mechanism of the temperature and humidity regulating unit involves adaptive adjustment of the initialization logic circuit: the temperature and humidity regulating unit includes temperature regulation (cooling / heating) and humidity regulation (dehumidification / humidification). To improve the adaptability of the unit, adjustments need to be made according to the actual operating characteristics of the unit.

[0051] In one specific embodiment, the cooling module needs 30 seconds to reach the stable cooling efficiency optimization adjustment threshold after startup. For example, when the relative temperature difference reaches 1°C, if there is a startup delay in the unit's cooling module, the circuit will trigger the startup command 5 seconds in advance to ensure that the set temperature is reached within the target time.

[0052] After the above adjustments, the logic drive circuit is determined, and its control program is written into the microcontroller. The microcontroller is used as the logic execution carrier, which can receive sensor group data and output adjustment commands in real time.

[0053] Subsequently, the microcontroller is connected to the unit controller. After configuration, the unit controller can obtain the correction logic of the logic drive circuit through the microcontroller. For example, when the first sensor group in the flow field loop detects that the humidity in the middle of the cabinet is 60%, which is higher than the 55% standard stored in the first register, and the second sensor group still shows 56% due to a 15-second transmission delay, the microcontroller sends a dehumidification command to the unit controller in advance based on the second relative compensation logic, so that the dehumidification module of the temperature and humidity regulating unit starts in advance to avoid the humidity from continuing to rise due to signal lag. At the same time, combined with the first relative adjustment logic, the dehumidification module is controlled to operate at 80% power according to the 5% humidity difference, so as to achieve precise regulation.

[0054] Furthermore, the first register has time zone validity, and the second register has instant validity; the temperature and humidity conditions are written into the first register, wherein the periodic time period is used as the valid time zone of the first register.

[0055] In this application, the first register has time zone validity, that is, the information stored therein only has a regulatory effect on the temperature and humidity regulation process within a preset periodic time, and will not participate in the regulation logic outside of that periodic time; the second register has instant validity, that is, the information stored therein immediately takes effect on the current temperature and humidity regulation control after being written, and is dynamically updated or cleared as the regulation process progresses.

[0056] Specifically, the temperature and humidity conditions are written into the first register. These conditions are converted constant temperature and humidity control parameters for a period of time that the unit can recognize. The period of time is used as the effective time zone of the first register.

[0057] For example, a certain cultural and tourism calligraphy and painting exhibition area sets the temperature at 20℃ and humidity at 50% from 9:00 to 17:00 every day, and the temperature at 18℃ and humidity at 45% from 17:00 to 9:00 the next day, based on the needs of protecting the exhibits. These two periodic periods correspond to the two effective time zones of the first register.

[0058] S3: By executing dual-sided temperature and humidity sensing based on the first and second sensor groups, the flow field loop is updated, and the logic drive circuit is assisted to reverse-engineer the unit parameters for temperature and humidity control based on the correction of the flow field loop, write them into the second register, and execute the parameter control drive management of the temperature and humidity control unit. The control dimension includes the first relative adjustment based on relative temperature and humidity, and the second relative compensation based on relative signal time delay.

[0059] In this embodiment, dual-sided temperature and humidity sensing based on a first sensor group and a second sensor group is implemented. The first sensor group corresponds to the system temperature and humidity sensor located in the middle of the equipment enclosure, which collects the actual temperature and humidity of the space inside the enclosure. The second sensor group corresponds to the unit temperature and humidity sensor at the return air vent, which collects the temperature and humidity of the air entering the temperature and humidity regulating unit. By simultaneously acquiring temperature and humidity data from two key locations, dual-sided sensing forms a spatial temperature and humidity distribution reference, providing a basis for subsequent flow field analysis.

[0060] Subsequently, the flow field loop is updated based on the aforementioned dual-side sensor data. The core of the flow field loop is the path of airflow from the outlet through the duct to the return air outlet. That is, the air flows from the outlet duct and outlet to the top of the housing, then flows from the left side of the top to the right side, descends to the right side of the bottom, and then flows to the left to the return air outlet. By combining the temperature and humidity difference between the first and second sensor groups, the temperature and humidity loss pattern of the airflow during the circulation process can be determined. For example, if the temperature of the airflow naturally decreases by 1°C from the middle of the housing to the return air outlet, the temperature and humidity data of the locations not directly detected in the flow field are supplemented by interpolation, thereby realizing the dynamic update of the flow field loop and making it more consistent with the actual temperature and humidity distribution in the airflow circulation.

[0061] The updated flow field loop provides real-time temperature and humidity information, which assists the logic drive circuit in optimizing its adjustment logic. The logic drive circuit is deployed based on the principle of relative correction, its core being the correction of adjustment commands through spatial temperature and humidity differences and airflow transmission delays. For example, after the flow field loop is updated, if the transmission delay from the air outlet to the return air outlet is determined to be 20 seconds, and the first sensor group detects a humidity of 60% in the middle of the enclosure, higher than the set 55%, while the second sensor group, due to the delay, has not yet detected the corresponding change and still displays 57%, the delay data provided by the flow field loop can assist the circuit in triggering the dehumidification preparation command 20 seconds in advance, avoiding untimely adjustment due to signal lag.

[0062] In this application, the unit parameters for temperature and humidity control are derived by reversing the correction based on the flow field loop. Specifically, in a preferred embodiment, based on the updated transmission loss law of temperature and humidity in the flow field, for example, after flow field analysis, the air processed by the temperature and humidity control unit will naturally increase in temperature by 1°C from the air outlet to the middle of the housing. If the first sensor group detects that the current temperature in the middle of the housing is 23°C and the target temperature is 22°C, it can be deduced that the temperature and humidity control unit needs to set the air outlet temperature to 21°C to offset the 1°C natural temperature rise so that the middle of the housing can eventually reach the target temperature. Similarly, for humidity control, if the humidity in the flow field decreases by 3% from the air outlet to the middle, it can be deduced that the unit needs to set the air outlet humidity to 58% and the target humidity in the middle to 55%. The unit operating parameters of 21°C and 58% after flow field correction are the unit parameters required for control.

[0063] Based on the above, according to the logic driving circuit, the temperature and humidity difference decision based on the first relative adjustment and the second relative compensation is executed to determine the unit parameters and write them into the second register. The second register is a storage unit with real-time validity. After the parameters are written, they immediately serve as the operating basis of the temperature and humidity control unit without waiting for the period to take effect. The temperature and humidity control unit can start adjustment immediately according to the parameters.

[0064] Meanwhile, the flow field loop continuously updates data through dual-sided sensors. If a change in airflow transmission loss is detected, such as a natural temperature rise of 0.8℃ due to ambient temperature fluctuations, the subsequent logic is fine-tuned to achieve dynamic drive management and ensure that the constant temperature and humidity environment required for cultural and tourism scenarios is always maintained.

[0065] Furthermore, updating the flow field loop, step S3 of this application includes:

[0066] Based on the first sensor group, temperature and humidity data of the internal space of the unit are collected to determine the first temperature and humidity data; based on the second sensor group, temperature and humidity data of the return air vent are collected to determine the second temperature and humidity data; the first and second temperature and humidity data are used to initialize the flow field loop spatially to determine the temperature and humidity flow field, wherein the spatial data distribution of the flow field loop is smoothed by interpolation, and the flow field loop is built into the unit controller.

[0067] In this embodiment, the temperature and humidity of the internal space of the unit are collected based on the first sensor group to determine the first temperature and humidity data. The first sensor group corresponds to the temperature and humidity sensors inside the equipment enclosure, and its function is to provide the actual temperature and humidity reference values ​​inside the enclosure, which is the first temperature and humidity data.

[0068] Similarly, based on the temperature and humidity data collected at the return air vent location using the second sensor group, the second temperature and humidity data is determined. The second sensor group corresponds to the temperature and humidity sensor at the return air vent, which is the inlet for air from inside the unit to enter the temperature and humidity control unit. The temperature and humidity data at this location reflects the state of the air to be processed by the unit and, as the second temperature and humidity data, can provide a direct reference for the adjustment intensity of the temperature and humidity control unit.

[0069] Subsequently, the flow field loop is spatially initialized using the first and second temperature and humidity data to determine the temperature and humidity flow field. The airflow path of the flow field loop is as follows: the air processed by the temperature and humidity control unit is sent to the top of the housing through the air outlet duct and air outlet, then flows from the left side of the top to the right side, descends to the right side of the bottom, and then flows to the left to enter the return air inlet.

[0070] Specifically, the first and second temperature and humidity data are parameters of two key nodes in the flow field. Based on the temperature and humidity values ​​of these two nodes, a preliminary framework for the temperature and humidity distribution along the airflow circulation path can be constructed.

[0071] In this application, the spatial data distribution of the flow field loop is smoothed using interpolation. Since the first and second sensor groups can only collect temperature and humidity data at two specific locations, while the flow field loop covers multiple spatial areas such as the top and bottom of the housing, the interpolation method can use the known data from two nodes to estimate the temperature and humidity at other locations. Based on the aforementioned technical concept, the temperature and humidity loss pattern of the airflow during circulation is used as a constraint; for example, linear interpolation can be used to deploy scattered temperature and humidity data. Any feasible interpolation method can be used in the implementation of this application. This expands the temperature and humidity data in the flow field loop from discrete points to a continuous spatial distribution, avoiding data gaps and determining the temperature and humidity flow field.

[0072] The flow field loop is built into the unit controller. The temperature and humidity flow field data after spatial initialization and data smoothing will be stored and called by the unit controller. The unit controller can determine whether the temperature and humidity regulating unit can cover the entire box space based on the temperature and humidity distribution pattern at different locations in the flow field.

[0073] For example, if the temperature at the top of the enclosure is too high, the temperature regulation at the top can be enhanced by adjusting the airflow direction of the exhaust duct, thereby achieving precise control of the constant temperature and humidity environment inside the enclosure.

[0074] Furthermore, the unit parameters for temperature and humidity control are inversely derived based on the correction of the flow field loop and written into the second register. Step S3 of this application includes:

[0075] By triggering the connected microcontroller, the first derivation decision is executed based on the relative difference between the temperature and humidity conditions and the temperature and humidity flow field written into the first register, and the first adjustment strategy is determined; the pre-control unit parameters of the first adjustment strategy are determined, and the second compensation strategy is determined based on the second compensation decision of the relative signal delay; the second compensation strategy is written into the second register.

[0076] In this embodiment of the application, a microcontroller is triggered for access. This microcontroller, as the logic execution core, has pre-stored control logic based on flow field loop correction and can receive temperature and humidity flow field data in real time and call the reference data of the first register.

[0077] The temperature and humidity conditions written into the first register represent the periodic control targets in the cultural and tourism scenario, while the temperature and humidity flow field represents the spatial temperature and humidity distribution data collected and interpolated by the first and second sensor groups. The relative difference between the two represents the deviation between the actual flow field and the target conditions, and the microcontroller executes the first derivation decision based on this difference. For example, when the temperature difference exceeds 1°C and the humidity difference exceeds 3%, a first adjustment strategy of simultaneously activating cooling and dehumidification functions is determined; if only a single parameter exceeds the limit, only the corresponding adjustment function is activated. Simultaneously, the adjustment scale is determined based on the specific difference value.

[0078] Subsequently, the pre-control unit parameters of the first regulation strategy are determined, that is, the operating parameters of the temperature and humidity regulating unit are quantified according to the relative difference. For example, when the temperature difference is 1.5℃ (0.5℃ exceeding the 1℃ threshold), the pre-control parameters are set to the refrigeration module operating at 60% power, and the power increases by 20% for every 0.5℃ increase in the difference; when the humidity difference is 5% (2% exceeding the 3% threshold), the pre-control parameters are set to the dehumidification module operating at 50% power (the power increases by 10% for every 1% increase in the difference).

[0079] Subsequently, a second compensation strategy is determined based on a second compensation decision based on relative signal delay. Specifically, based on the relative signal delay—the physical delay of airflow from the outlet to the return air outlet—the second compensation decision is executed when the measured delay in this scenario is 20 seconds, meaning the second sensor group's signal lags behind the first sensor group by 20 seconds. For example, since signal lag may cause delays in unit adjustment response, time compensation is added to the pre-controlled parameters. This involves advancing the start-up time of the cooling and dehumidification modules by 15 seconds and reserving 5 seconds for unit start-up preparation time, preventing actual adjustment from lagging behind demand due to signal lag. This compensation results in a combined strategy for temperature and humidity control, which is the second compensation strategy.

[0080] Subsequently, the second compensation strategy is written into the second register, which is a storage unit that takes effect immediately. After the strategy is written, it can be triggered and executed without waiting for a period of time. The command is immediately sent to the temperature and humidity control unit controller, and then the cooling and dehumidification functions are started according to the set power.

[0081] Meanwhile, the microcontroller continuously acquires new temperature and humidity data through the flow field loop. If the relative difference in the flow field does not drop below the standard, the decision is re-derived and the second compensation strategy is updated to ensure that the precise control of temperature and humidity of the display case always meets the needs of the cultural and tourism scenario.

[0082] Furthermore, in implementing the parameter control and drive management of the temperature and humidity regulating unit, step S3 of this application includes:

[0083] The second register generates a vertical synchronization signal according to the second compensation strategy; and performs response control on the temperature and humidity regulating unit according to the vertical synchronization signal, wherein the second compensation strategy written in the second register is deleted as the vertical synchronization signal is transmitted.

[0084] In this embodiment of the application, the second register generates a vertical synchronization signal according to the second compensation strategy. The vertical synchronization signal is a control signal used to synchronize the operating rhythm of the temperature and humidity regulating unit. Its generation logic is bound to the execution timing of the second compensation strategy, which can ensure that the unit's regulation action is accurately matched with the time node of temperature and humidity changes in the flow field loop.

[0085] Subsequently, the temperature and humidity control unit is controlled in response to the vertical synchronization signal: the temperature control part of the temperature and humidity control unit, including cooling / heating, and the humidity control part, including dehumidification / humidification, will start operation based on the vertical synchronization signal.

[0086] For example, after the aforementioned vertical synchronization signal is issued, the temperature and humidity control unit responds by controlling the refrigeration module to start at 60% power. Its operating status is synchronized with the signal in real time. For instance, if the signal detects that the flow field temperature is close to the target value, the vertical synchronization signal will dynamically adjust the power command to 40%. This response control can avoid over-adjustment or under-adjustment caused by the unit's regulation not being synchronized with the actual temperature and humidity changes.

[0087] Specifically, as the vertical synchronization signal is transmitted, the second compensation strategy written to the second register is deleted. This ensures that the second register always maintains its responsiveness to the latest adjustment requirements. That is, once the vertical synchronization signal is transmitted to the temperature and humidity control unit and triggers the adjustment action, the original second compensation strategy has completed its mission. Deleting the strategy at this time can free up register storage resources, avoid conflicts between the old strategy and the subsequently generated strategy, and meet the continuous and stable requirements of constant temperature and humidity environment in cultural and tourism scenarios.

[0088] Furthermore, after implementing the parameter control and drive management of the temperature and humidity control unit, the steps in this application also include:

[0089] In response to the temperature and humidity control unit, the first and second sensor groups perform adjustment response sensing to determine temperature and humidity feedback data; according to the communication bus, the temperature and humidity feedback data is written into the second register, and data interaction verification based on the first and second registers is performed to generate a control response command. Among them, the temperature and humidity feedback data in the second register is deleted along with the generation of the control response command.

[0090] In this embodiment, in response to the temperature and humidity control unit, the first sensing group and the second sensing group perform adjustment response sensing, determine temperature and humidity feedback data, and reflect the actual temperature and humidity effect of the control measures.

[0091] Subsequently, according to the communication bus and its aforementioned routing network line, the temperature and humidity feedback data is written into the second register for comparison and verification with the reference data in the first register. Data interaction verification based on the first and second registers is performed: the first register stores the periodic temperature and humidity conditions of the cultural and tourism scenario, and the second register stores the current feedback data. A control response command is generated by comparing the difference between the two to determine whether the current control meets the constant temperature and humidity standard of the periodic time zone. For example, if it does not meet the standard, the control response command maintains the current dehumidification intensity; if the difference is close to the target, such as a temperature difference of 0.5℃, the control response command reduces the cooling power.

[0092] Specifically, upon the generation of the control response command, the temperature and humidity feedback data in the second register is deleted. This ensures that the second register always stores the latest feedback data: once the control response command is generated, the original feedback data has served its purpose, and the deletion operation frees up register space, preventing old data from interfering with subsequent verification processes. This allows for continuous adjustment of the temperature and humidity control strategy based on the latest environmental conditions, maintaining precise temperature and humidity control in cultural and tourism scenarios.

[0093] This application provides a method for controlling a constant temperature and humidity environment in a cultural and tourism setting, which has the following technical effects:

[0094] 1. The system collects the actual temperature and humidity inside the unit through the first sensor group (middle of the enclosure) and the temperature and humidity of the air entering the unit through the second sensor group (return air vent). This data, combined with the airflow circulation path (duct), forms a flow field loop, and the temperature and humidity flow field distribution is generated through interpolation and smoothing. This achieves comprehensive sensing of temperature and humidity within the enclosure, avoiding the limitations of single-sensor data collection, providing comprehensive data support for precise adjustment, and reducing temperature and humidity detection errors.

[0095] 2. Dual-Register Time-Sharing Storage and Collaborative Control: The first register stores the temperature and humidity conditions for a given period as a baseline; the second register stores real-time adjustment parameters for dynamic response. The two registers verify each other through data interaction to achieve collaborative control of period setting and real-time correction. This balances the basic needs of fixed time periods in cultural and tourism scenarios with the real-time adjustment needs of sudden environmental changes, avoiding parameter conflicts and improving control flexibility. Vertical Synchronization Signal Drive and Dynamic Update Technology: The second register generates a vertical synchronization signal based on a compensation strategy, synchronously controlling the operation of the temperature and humidity regulating unit, and deleting the old strategy after signal transmission. This achieves precise synchronization between adjustment commands and unit operation, avoiding over-adjustment or under-adjustment, reducing invalid data consumption, improving system operating efficiency, and ensuring the continuous stability of the constant temperature and humidity environment in cultural and tourism scenarios.

[0096] 3. The first relative adjustment (intensity correction) is performed based on the relative difference in temperature and humidity between the two sensor groups, and the second relative compensation (time correction) is performed based on the airflow transmission delay. The correction logic is written into the unit controller via a microcontroller. This solves the problems of signal lag and spatial distribution differences in temperature and humidity regulation, avoids regulation lag caused by airflow transmission delay, improves the unit's response speed, and ensures that the temperature and humidity inside the chamber quickly stabilize within the target range.
