Description

Technical Field

[0001] This invention relates to the field of tea storage technology, specifically to a Pu'er tea storage warehouse and its control method. Background Technology

[0002] Pu-erh tea, a geographical indication protected product of Yunnan Province, is hailed as a "drinkable living antique" due to its unique storage value, health benefits, and appreciation potential, making it highly sought after by tea lovers. The formation of a high-quality Pu-erh tea relies on three key elements: superior raw materials, exquisite craftsmanship, and scientific storage. Good storage conditions allow the flavor and quality of Pu-erh tea to gradually improve. Therefore, proper storage is crucial for Pu-erh tea, maximizing its quality and creating greater economic benefits.

[0003] The article "Research Progress on Factors Affecting the Storage and Quality Changes of Pu'er Tea" published in Volume 46, Issue 2 (June 2019) of Tea Communications points out that the key factors for Pu'er tea storage mainly include moisture, temperature, light, oxygen, and pressure, among which the degree of influence is usually temperature > oxygen > moisture > light.

[0004] It is evident that temperature is the most crucial factor in achieving scientific storage of Pu'er tea. How to accurately control the temperature of tea storage and reduce temperature fluctuations is a topic worthy of research. Summary of the Invention

[0005] One of the objectives of this invention is to provide a method for controlling the storage temperature of Pu'er tea, aiming to achieve stable storage temperature in the tea warehouse.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A method for controlling a Pu-erh tea storage warehouse, comprising:

[0008] An outer wall is provided outside the tea storage body to form an isolation channel surrounding the tea storage body;

[0009] Several temperature detection points are configured in the isolation channel described above, and a temperature sensor is configured at each temperature detection point;

[0010] The isolation channel is equipped with an air conditioning duct and several circulating fans. The air conditioning duct is equipped with an independent air outlet corresponding to each temperature detection point.

[0011] Configure the controller, set the first temperature threshold T1 and the second temperature threshold T2, collect the temperature Tp of each temperature detection point, calculate the average temperature Ta of the isolation channel, and calculate ΔT=|Tp-Ta|; when a certain temperature detection point satisfies T1<ΔT≤T2, turn on the circulating fan until ΔT≤T1; when a certain temperature detection point satisfies ΔT>T2, start the air conditioner and open the independent air outlet of the air conditioner duct corresponding to that temperature detection point until ΔT≤T1.

[0012] Furthermore, the controller performs anomaly detection before calculating the average temperature Ta:

[0013] Obtain the orientation and sunlight model of the tea storage body, match the sunlight model according to the orientation of the tea storage body, record the outdoor temperature value Tt1 at historical time t1, the light intensity Lt1 at each temperature detection point and the temperature Tpt1 at each temperature detection point, and establish a mapping table with the outdoor temperature value Tt1 and the light intensity Lt1 at each temperature detection point as indexes and the temperature Tpt1 interval of each temperature detection point as the result.

[0014] Set a third temperature threshold T3 and a fourth temperature threshold T4;

[0015] Obtain the outdoor temperature value Tt at the current time t, the light intensity Lt at each temperature detection point, and query the corresponding Tpt1 interval;

[0016] The system checks whether the temperature Tpt of each temperature detection point at the current time t falls within the Tpt1 interval. If yes, the anomaly detection process terminates. If no, it calculates the deviation value ΔTpt, where ΔTpt = |Tpt - Tpt1|. When a temperature detection point satisfies T3 < ΔTpt ≤ T4, it outputs an anomaly alert for that temperature detection point. When a temperature detection point satisfies Tpt > T4, it checks whether other temperature detection points have Tpt falling within the Tpt1 interval. If no, it outputs a temperature anomaly alert; if yes, it outputs an anomaly alarm for that temperature detection point.

[0017] Furthermore, several sealed skylights are provided on the east and west sides of the outer wall;

[0018] The controller also performs the following: when there is a need for light at the receiving end, it acquires the light intensity Lt at each temperature detection point and selects one or more light-collecting windows with the weakest light intensity Lt to open the blackout curtains for light collection.

[0019] Furthermore, a first air inlet is provided on the north side of the outer wall, and a first air outlet is provided on the south side of the outer wall, with a first fan installed on the first air outlet.

[0020] The second objective of this invention is to provide a Pu'er tea storage warehouse that implements the aforementioned control method to achieve stable storage temperature.

[0021] A Pu-erh tea storage warehouse, comprising:

[0022] Tea warehouse body;

[0023] An outer wall is configured around the tea storage body to form an isolation channel; the outer wall surrounds the tea storage body to form an isolation channel, and the isolation channel is equipped with several temperature detection points;

[0024] Several temperature sensors, each of which is distributed at a temperature detection point;

[0025] An air conditioning duct is provided in the isolation channel and surrounds the tea storage body. The air conditioning duct has several independent air outlets corresponding to each temperature detection point.

[0026] A plurality of circulating fans are arranged around the isolation channel;

[0027] The controller is used to execute the control method for Pu'er tea storage warehouses as described above.

[0028] The outer wall has a first air inlet on the north side and a first air outlet on the south side, with a first fan installed on the first air outlet; the tea storage body includes several storage rooms, each of which has a second air inlet and a second air outlet on the east / west side corresponding to the isolation channel, with a second fan installed on the second air outlet.

[0029] Furthermore, the second air inlet and the second air outlet are located on the same side, and a baffle is provided in the storage chamber between the second air inlet and the second air outlet for separation.

[0030] Furthermore, the allowable opening time for ventilation of the second air inlet and the second air outlet is 7-10 hours and 18-21 hours, respectively; when the humidity of the storage room exceeds the preset value, the allowable opening time for ventilation of the second air inlet and the second air outlet is 18-21 hours.

[0031] Furthermore, the wall of the second air outlet is recessed relative to the storage room to form a concave wall.

[0032] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0033] 1. The present invention has an outer wall configured outside the tea storage body to form an isolation channel around the tea storage body, creating a certain temperature difference between the indoor and outdoor storage rooms. This can combine with the regional climate to provide Pu'er tea with a more stable environment that adapts to the changing seasons, meeting the aging requirements of Pu'er tea. It also mainly relies on physical temperature regulation to achieve energy saving.

[0034] 2. This invention sets up several temperature detection points in the isolation channel to monitor the temperature and prevent the temperature in some areas of the isolation channel from becoming too high, which could affect the storage of Pu'er tea in the tea warehouse. Different temperature control strategies are set up to deal with temperature changes, so as to achieve energy saving.

[0035] 3. This invention performs anomaly detection at temperature detection points to ensure the active safety of the tea storage and avoid the risk of huge losses due to temperature sensor malfunction or failure.

[0036] 4. By setting the orientation and lighting direction of the tea storage body, this invention further adjusts the influence of humidity and light on the storage of Pu'er tea, creating more scientific conditions for the storage of Pu'er tea. Attached Figure Description

[0047] Example 1

[0048] Please refer to Figure 1 As shown, the present invention discloses a Pu'er tea storage chamber, which includes a tea chamber body 100, an outer wall 200, several temperature sensors 300, an air conditioning duct 400, several circulating fans 500 and a controller.

[0049] The tea storage unit 100 includes several storage rooms 110 to store Pu'er tea from different years, separating raw and ripe tea, as well as new and aged tea.

[0050] The outer wall 200 is set outside the tea storage body 100 to form an isolation channel 210 around the tea storage body 100, creating a certain temperature difference between the inside and outside of the storage room 110, reducing the impact of outdoor temperature fluctuations on the temperature of the tea storage body 100; the isolation channel 210 is equipped with several temperature detection points.

[0051] Several temperature sensors 300 are distributed at various temperature detection points to monitor the temperature.

[0052] The air conditioning duct 400 is set in the isolation channel 210 and surrounds the tea storage body 100. The air conditioning duct 400 has several independent air outlets corresponding to each temperature detection point. The independent air outlets can be opened and closed by electric valves. The electrification of the air damper is existing technology and will not be described in detail here.

[0053] Similarly, several circulating fans 500 are also arranged around the isolation channel 210 and are set at several points along the path of the air conditioning duct 400.

[0054] The controller is used to collect the parameters from the temperature sensor 300 and to control the operation of the air conditioner, damper, and circulating fan 500. Its function will be...

[0055] In a more preferred embodiment, a first air inlet 211 is provided on the north side of the outer wall 200, and a first air outlet 212 is provided on the south side of the outer wall 200. A first fan 213 is provided on the first air outlet 212. Taking into account the wind direction, the north wind is used for ventilation. The north wind has relatively low humidity, which is generally suitable for the temperature and humidity control requirements of the tea warehouse.

[0056] In a more preferred embodiment, each storage chamber 110 is provided with a second air inlet 111 and a second air outlet 112 on the east / west side corresponding to the isolation channel 210, and a second fan 113 is provided on the second air outlet 112. The second air inlet 111 of each storage chamber 110 is located on the north side of the second air outlet 112 to improve ventilation efficiency.

[0057] In this way, the temperature and humidity of each storage room 110 are normally balanced through the isolation channel 210. However, during regular ventilation or in special circumstances (such as when the temperature is too high in summer), please refer to... Figure 2 As shown in the upper left corner of the storage room 110, the isolation channel 210 and the second air inlet 111 and the second air outlet 112 of the corresponding storage room 110 are opened for regulation.

[0058] In each storage chamber 110, the second air inlet 111 and the second air outlet 112 are located on the same side to facilitate air exchange with the isolation channel 210. To ensure uniform air exchange in each storage chamber 110, a baffle 120 is provided between the second air inlet 111 and the second air outlet 112 for separation. Although the second air inlet 111 and the second air outlet 112 are located on the same side due to the presence of the isolation channel 210, they form a diagonal flow channel, which makes the air mix more evenly in the tea storage chamber during air exchange.

[0059] In a preferred embodiment, the wall of the second air outlet 112 is recessed relative to the storage chamber 110 to form a recessed wall 220, thereby reducing the impact of the airflow discharged from the second fan 113 on the isolation channel 210.

[0060] In a preferred embodiment, the second fan 113 is installed on the outside of the recessed wall 220, and the first fan 213 is installed on the inside of the isolation channel 210, which facilitates the cleaning and maintenance of the fans.

[0061] The control method and working principle of the Pu'er tea storage chamber in this embodiment will be further discussed in Embodiment 2, and will not be repeated in this embodiment.

[0062] Example 2

[0063] In another aspect, this invention provides a control method for Pu'er tea storage based on the hardware shown in Embodiment 1, aiming to achieve stable storage temperature in the tea storage.

[0064] Please refer to Figure 3 As shown, the controller is configured to: set a first temperature threshold T1 and a second temperature threshold T2, collect the temperature Tp of each temperature detection point, calculate the average temperature Ta of the isolation channel 210, and calculate ΔT=|Tp-Ta|; when a certain temperature detection point satisfies T1<ΔT≤T2, turn on the circulating fan 500 until ΔT≤T1; when a certain temperature detection point satisfies ΔT>T2, start the air conditioner and open the independent air outlet of the air conditioning duct 400 corresponding to that temperature detection point until ΔT≤T1.

[0065] Thus, temperature detection is performed according to a set cycle (e.g., one hour): First, the average temperature Ta of the isolation channel 210 is calculated based on the temperature Tp of each temperature detection point. Using the average temperature Ta as a reference improves the robustness of the system. Second, when the temperature value at a certain temperature detection point is abnormal (too high or too low, usually due to localized overheating caused by sunlight), if the overtemperature value is less than the first threshold, simply turning on the circulating fan 500 to circulate the isolation channel 210 achieves temperature balance. However, when a certain overtemperature point is too high, due to the heat storage and insulation effect of the wall, relying solely on the circulating fan 500 will take a long time to normalize the temperature of the local overtemperature point. Therefore, at this time, by turning on the air conditioner and its corresponding independent air outlet, cold air is introduced to lower the temperature below the first threshold, roughly offsetting the heat storage of the wall, and then the circulating fan 500 circulates the air to stabilize the temperature. In a feasible implementation, the first temperature threshold T1 can be configured to 3℃, and the second temperature threshold T2 can be configured to 5℃.

[0066] Please refer to Figure 4 As shown, in a more preferred embodiment, the controller also performs anomaly detection before calculating the average temperature Ta:

[0067] Obtain the orientation and sunlight model of the tea storage unit 100. Match the sunlight model according to the orientation of the tea storage unit 100, and record the outdoor temperature value Tt1, light intensity Lt1, and temperature Tpt1 of each temperature detection point at historical time t1. Establish a mapping table with the outdoor temperature value Tt1 and the light intensity Lt1 of each temperature detection point as indexes, and the temperature Tpt1 interval of each temperature detection point as the result. It is easy to understand that when clustering the outdoor temperature value Tt1 and the light intensity Lt1 of each temperature detection point, a certain deviation is allowed. That is, the outdoor temperature value Tt1 and the light intensity Lt1 of each temperature detection point obtained by clustering are actually a range of values. Similarly, the corresponding temperature Tpt1 interval is also a range of values. Obtain values ​​of a certain period (such as one year) as basic data, and continuously update this data thereafter.

[0068] Set the third temperature threshold T3 and the fourth temperature threshold T4;

[0069] Obtain the outdoor temperature value Tt at the current time t, the light intensity Lt at each temperature detection point, and query the corresponding Tpt1 interval;

[0070] The system checks whether the temperature Tpt of each temperature detection point at the current time t falls within the Tpt1 interval. If yes, the anomaly detection process terminates. If no, it calculates the deviation value ΔTpt, where ΔTpt = |Tpt - Tpt1|. When a temperature detection point satisfies T3 < ΔTpt ≤ T4, it outputs an anomaly alert for that temperature detection point. When a temperature detection point satisfies Tpt > T4, it checks whether other temperature detection points have Tpt falling within the Tpt1 interval. If no, it outputs a temperature anomaly alert; if yes, it outputs an anomaly alarm for that temperature detection point.

[0071] Thus, when the deviation between the actual collected temperature value and the historical value at a certain temperature detection point is within T3 and T4, an anomaly may occur, and an anomaly alert will be output to remind staff to investigate. Conversely, when the deviation between the actual collected temperature value and the historical value at a certain temperature detection point exceeds T4, but the temperatures at other temperature detection points all fall within the Tpt1 range, the sensor at that temperature detection point is determined to be faulty, and an anomaly alarm will be immediately output to urge staff to check and troubleshoot the problem. In one specific implementation, T3 is set to 3°C and T4 is set to 5°C.

[0072] In addition, the second air inlet 111 and the second air outlet 112 are permitted to be opened for ventilation from 7:00 to 10:00 and from 18:00 to 21:00, respectively, to facilitate ventilation with the isolation channel 210 when the temperature is too high in summer, thereby reducing the need for air conditioning in the storage room 110. When the humidity in the storage room also fails to meet the requirements and exceeds the preset value, the second air inlet 111 and the second air outlet 112 are permitted to be opened for ventilation from 18:00 to 21:00.

[0073] Furthermore, this invention includes several sealed light-transmitting windows 115 on the east and west sides of the outer wall 200. These windows 115 are located between the second air inlet 111 and the second air outlet 112. The controller also performs the following: when there is a need for light at the receiving end, it acquires the light intensity Lt at each temperature detection point and selects one or more light-transmitting windows 115 with the weakest light intensity Lt to open the blackout curtains. In this way, the light requirements are met, the light needs of the microbial community are adjusted, and a better aging environment is created, while direct sunlight is avoided, which could affect the quality of the Pu-erh tea.

[0074] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
