Description

Technical Field

[0001] The present invention relates to the technical field of medicinal material growth environment control, and in particular to a medicinal material growth environment control system based on Lora. Background Art

[0002] In the traditional process of medicinal material planting, the monitoring and control of environmental parameters mainly rely on manual operation, which has problems such as inaccurate monitoring data and untimely regulation. With the development of Internet of Things technology, more and more intelligent equipment is being used in agricultural production. However, most of the existing agricultural Internet of Things systems have problems such as limited signal coverage and high power consumption. Therefore, in order to meet the needs of large-scale medicinal material planting bases, it is particularly important to develop a medicinal material growth environment control system based on Lora.

[0003] The above existing technologies still have the following problems: 1. The temperature and humidity control type is not confirmed according to the changes in air temperature and humidity in the greenhouse for growing medicinal materials, and thus precise temperature and humidity control is not performed according to the temperature and humidity control type. If the temperature and humidity in the greenhouse are not properly controlled, the growth of medicinal materials may be hindered, resulting in problems such as slow growth and poor development, while reducing the quality of the medicinal materials, thereby affecting their medicinal value, and further affecting the economic benefits of the growers.

[0004] 2. The causes of abnormal development of medicinal materials are not identified in combination with their own growth and development during the growth cycle, and the growth environment of medicinal materials is not regulated according to the causes of abnormal development. Developmental abnormalities cannot be identified and dealt with in a timely manner, which may lead to a significant decline in the overall yield of medicinal materials. At the same time, scientific growth environment regulation strategies cannot be formulated based on the growth needs and sensitivity of medicinal materials, which reduces the yield of medicinal materials, increases the risk of diseases and pests, and fails to achieve effective utilization of resources and sustainable development of the environment. Summary of the invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a medicinal material growth environment control system based on lora is proposed.

If not, the medicinal material growth environment control module is executed. If normal, there is no need to control the medicinal material growth environment.

[0009] The medicinal material growth environment control module is used to record medicinal materials with abnormal development status as target medicinal materials, extract the soil conductivity of each target medicinal material in the current growth cycle, confirm the cause of the abnormal development of each target medicinal material in the current growth cycle, and control the medicinal material growth environment according to the cause of the abnormal development.

[0010] The database is used to store the ventilation time and humidification time corresponding to the unit humidity deviation, the heating time and heat dissipation time corresponding to the unit temperature deviation, the leaf color set corresponding to the normal development of the medicinal materials in the current growth cycle, and the appropriate growth light supplementation time corresponding to the unit leaf growth deviation.

[0011] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0012] (1) The present invention determines the type of temperature and humidity control according to the changes in air temperature and humidity in the greenhouse for growing medicinal materials, and thus performs precise temperature and humidity control according to the type of temperature and humidity control, thereby avoiding the growth of medicinal materials being hindered due to improper temperature and humidity control in the greenhouse, and avoiding problems such as slow growth and poor development. At the same time, the quality of the medicinal materials is improved, thereby avoiding affecting their medicinal value, and further increasing the economic benefits of the growers.

[0013] (2) The present invention identifies the cause of abnormal development of medicinal materials by combining the growth and development of the medicinal materials themselves during the growth cycle, thereby regulating the growth environment of the medicinal materials according to the cause of the abnormal development, closely monitoring the growth and development of the medicinal materials during the growth cycle, promptly identifying and treating the abnormal development, and formulating a scientific growth environment regulation strategy based on the growth needs and sensitivity of the medicinal materials. By accurately regulating and optimizing the planting environment, the yield and quality of the medicinal materials can be improved, the risk of pests and diseases can be reduced, and the effective use of resources and sustainable development of the environment can be achieved.

[0020] The greenhouse environment monitoring module is connected to the greenhouse temperature and humidity control module, the medicinal material development status assessment module is connected to the medicinal material growth environment control module, and the greenhouse temperature and humidity control module, the medicinal material development status assessment module and the medicinal material growth environment control module are all connected to the database.

[0021] See also Figure 2 As shown, the greenhouse environment monitoring module is used to divide the target medicinal material planting greenhouse into various environmental monitoring areas, monitor the air temperature and humidity of each environmental monitoring area at each monitoring time point in each monitoring time period, and extract the optimal temperature and humidity range in the greenhouse corresponding to the growth of medicinal materials in the current growth cycle.

[0022] It should be noted that the air temperature and humidity corresponding to each monitoring time point in each monitoring time period in each environmental monitoring area are collected by temperature sensors and humidity sensors installed in each environmental monitoring area respectively, and the optimal temperature and humidity range in the greenhouse corresponding to the growth of medicinal materials in the current growth cycle is extracted from the breeding requirements manual of the target medicinal material planting greenhouse.

[0023] The greenhouse temperature and humidity control module is used to confirm the temperature and humidity control type corresponding to each environmental monitoring area in each monitoring time period, and perform temperature and humidity control according to the temperature and humidity control type.

[0024] In a specific embodiment of the present invention, the specific process of confirming the temperature and humidity control type corresponding to each environmental monitoring area in each monitoring time period is as follows: based on the air temperature and humidity corresponding to each monitoring time point in each environmental monitoring area in each monitoring time period and the optimal temperature and humidity range in the greenhouse corresponding to the growth of medicinal materials in the current growth cycle, the temperature deviation index β corresponding to each environmental monitoring area in each monitoring time period is calculated respectively. ij and humidity deviation index χ ij , where i represents the number of the environmental monitoring area, i=1,2,...,n, and j represents the number of the monitoring time period, j=1,2,...,m.

[0025] In a specific embodiment of the present invention, the specific process of respectively calculating the temperature deviation index and humidity deviation index corresponding to each environmental monitoring area in each monitoring time period is as follows: comparing the air temperature corresponding to each monitoring time point in each environmental monitoring area in each monitoring time period with the optimal temperature range in the greenhouse corresponding to the growth of medicinal materials in the current growth cycle; if the air temperature corresponding to a monitoring time point in a certain environmental monitoring area in a certain monitoring time period is not within the optimal temperature range in the greenhouse corresponding to the growth of medicinal materials in the current growth cycle, then the monitoring time point is recorded as a temperature abnormal time point; the number of temperature abnormal time points in each environmental monitoring area in each monitoring time period is counted and recorded as ε ij .

[0026] The air temperature corresponding to each abnormal temperature time point in each environmental monitoring area in each monitoring time period is subtracted from the middle value of the temperature in the optimal temperature range in the greenhouse corresponding to the growth of medicinal materials in the current growth cycle to obtain the temperature deviation corresponding to each abnormal temperature time point in each environmental monitoring area in each monitoring time period, and the maximum value is extracted as the temperature deviation of each environmental monitoring area in each monitoring time period, which is recorded as W ij .

[0027] Calculate the temperature deviation index β corresponding to each environmental monitoring area in each monitoring time period ij , Among them, ε′ and W′ represent the number of temperature anomaly time points and temperature deviation of the set reference, respectively.

[0028] According to the analysis method of the temperature deviation index corresponding to each environmental monitoring area in each monitoring time period, the humidity deviation index χ corresponding to each environmental monitoring area in each monitoring time period is analyzed in the same way. ij .

[0029] Establish a temperature and humidity control type diagnosis model corresponding to each environmental monitoring area in each monitoring time period, and output the temperature and humidity control type diagnosis result, where the temperature and humidity control type diagnosis model is expressed as:

[0030] in,

[0031] β′ and χ′ represent the temperature deviation index and humidity deviation index of the set reference, respectively.

[0032] In a specific embodiment of the present invention, the specific process of performing temperature and humidity control according to the temperature and humidity control type is: if the temperature and humidity control type diagnosis result of a certain environmental monitoring area in a certain monitoring time period is that the temperature and humidity remain unchanged, then the monitoring time period is recorded as a constant time period, and there is no need to perform temperature and humidity control for each constant time period in each environmental monitoring area.

[0033] If the temperature and humidity control type diagnosis result of a certain environmental monitoring area in a certain monitoring time period is humidity control, then the monitoring time period is recorded as the humidity control time period, and humidity control is performed on each humidity control time period in each environmental monitoring area.

[0034] In a specific embodiment of the present invention, the specific method of performing humidity control in each humidity adjustment time period in each environmental monitoring area is: the air humidity corresponding to each monitoring time point in each humidity adjustment time period in each environmental monitoring area is averaged to obtain the average humidity of each humidity adjustment time period in each environmental monitoring area, and recorded as Here, g represents the number of the humidity adjustment time period, g=1, 2, ..., p.

[0035] The middle value of the humidity in the optimal humidity range in the greenhouse corresponding to the growth of medicinal materials is recorded as τ 中 .

[0036] The ventilation time and humidification time corresponding to the unit humidity deviation are extracted from the database and recorded as T 通 and T 加 .

[0037] like Indicates that dehumidification is required. As the ventilation time of each humidity adjustment period in each environmental monitoring area, if It indicates that the humidifier needs to be used for humidification. As the humidification time of the humidifier in each humidity adjustment time period in each environmental monitoring area.

[0038] If the temperature and humidity control type diagnosis result of a certain environmental monitoring area in a certain monitoring time period is temperature adjustment, then the monitoring time period is recorded as the temperature adjustment time period, and temperature control is performed on each temperature adjustment time period in each environmental monitoring area.

[0039] In a specific embodiment of the present invention, the specific method of temperature control in each temperature adjustment time period in each environmental monitoring area is: the air temperature corresponding to each monitoring time point in each temperature adjustment time period in each environmental monitoring area is averaged to obtain the average temperature of each temperature adjustment time period in each environmental monitoring area, and recorded as Here, r represents the number of the temperature adjustment time period, r=1, 2, ..., q.

[0040] The middle temperature value in the optimal temperature range in the greenhouse corresponding to the growth of medicinal materials is recorded as W 中 .

[0041] The heating time and cooling time corresponding to the unit temperature deviation are extracted from the database and recorded as T 加热 and T 散热 .

[0042] like This indicates that heat dissipation work is needed. As the heat dissipation duration of each temperature adjustment period in each environmental monitoring area, if Indicates that heating is required. As the heating time length of each temperature adjustment time period in each environmental monitoring area.

[0043] If the temperature and humidity control type diagnosis result of a certain environmental monitoring area in a certain monitoring time period is temperature and humidity adjustment, then the monitoring time period is recorded as the temperature and humidity adjustment time period, and temperature and humidity adjustment are performed in each temperature and humidity adjustment time period in each environmental monitoring area.

[0044] It should be noted that the method for controlling the temperature and humidity in each temperature and humidity adjustment time period in each environmental monitoring area is: controlling the humidity in each temperature and humidity adjustment time period in each environmental monitoring area in the same way as controlling the humidity in each humidity adjustment time period in each environmental monitoring area, and controlling the temperature in each temperature and humidity adjustment time period in each environmental monitoring area in the same way as controlling the temperature in each temperature adjustment time period in each environmental monitoring area.

[0045] The embodiment of the present invention confirms the temperature and humidity control type according to the changes in air temperature and humidity in the medicinal material planting greenhouse, and thus performs precise temperature and humidity control according to the temperature and humidity control type, thereby avoiding the growth of medicinal materials being hindered due to improper temperature and humidity control in the greenhouse, avoiding problems such as slow growth and poor development, and at the same time improving the quality of medicinal materials, thereby avoiding affecting their medicinal value, and thereby increasing the economic benefits of growers.

[0046] See also Figure 3As shown, the medicinal material development status evaluation module is used to collect the number of leaves, the area of ​​each leaf and the color of each leaf corresponding to each medicinal material in the target medicinal material planting greenhouse in the current growth cycle, and evaluate whether the development status of each medicinal material in the target medicinal material planting greenhouse in the current growth cycle is normal. If it is abnormal, the medicinal material growth environment control module is executed. If it is normal, there is no need to control the medicinal material growth environment.

[0047] It should be noted that the specific method for collecting the number of leaves, the area of ​​each leaf and the color of each leaf corresponding to each medicinal material in the target medicinal material planting greenhouse during the current growth cycle is: 1) Image acquisition: Use a high-resolution camera to photograph the medicinal plant to ensure that the image is clear and can capture all leaves, 2) Image preprocessing: Preprocess the collected image, including denoising, contrast enhancement, etc., to improve the accuracy of subsequent processing, 3) Leaf segmentation: Use an image segmentation algorithm to separate the leaves from the plant background. This usually involves existing technologies such as color space conversion, threshold segmentation, and edge detection. 4) Leaf counting: Identify and count the segmented leaves to obtain the number of leaves. 5) Area calculation: Use image recognition algorithm to accurately extract leaf contours. According to the extracted contours, the leaf area is calculated using the algorithm provided by the image processing software. 6) Color space conversion: Convert the image from RGB color space to a color space more suitable for color recognition, such as HSV or Lab color space. 7) Color analysis: Perform color analysis on the converted image to extract the main color features of the leaves. 8) Color quantization: Quantify the extracted color features into specific color values, such as the proportion of red, green, blue and other components or specific color names.

[0048] In a specific embodiment of the present invention, the specific process of evaluating whether the development state of each medicinal material in the target medicinal material planting greenhouse is normal in the current growth cycle is: based on the number of leaves, the area of ​​each leaf and the color of each leaf corresponding to each medicinal material in the target medicinal material planting greenhouse in the current growth cycle, the leaf color abnormality index corresponding to each medicinal material in the current growth cycle is calculated respectively. and leaf growth abnormality index θ f , where f represents the number of the medicinal material, f=1,2,...,z.

[0049] In a specific embodiment of the present invention, the specific process of calculating the leaf color abnormality index corresponding to each medicinal material in the current growth cycle is as follows: the leaf colors corresponding to each medicinal material in the target medicinal material planting greenhouse in the current growth cycle are compared with the leaf color set corresponding to the medicinal material when it develops normally in the current growth cycle stored in the database; if the leaf color corresponding to a certain medicinal material in the current growth cycle is within the leaf color set corresponding to the medicinal material when it develops normally in the current growth cycle, it indicates that the leaf is recorded as a normally developed leaf; the number of normally developed leaves corresponding to each medicinal material in the current growth cycle is counted, recorded as μf .

[0050] The number of leaves corresponding to each medicinal material in the target medicinal material planting greenhouse during the current growth cycle is recorded as

[0051] Calculate the leaf color abnormality index of each medicinal material in the current growth cycle Among them, K represents the percentage of normal development leaves set as the reference, and e represents the natural constant.

[0052] It should be noted that the specific process of calculating the leaf growth abnormality index corresponding to each medicinal material in the current growth cycle is: the average leaf area corresponding to each medicinal material in the target medicinal material planting greenhouse in the current growth cycle is calculated to obtain the average leaf area corresponding to each medicinal material in the target medicinal material planting greenhouse in the current growth cycle, and record it as

[0053] Calculate the leaf growth abnormality index θ corresponding to each medicinal material in the current growth cycle f , Among them, S′ and μ′ represent the leaf area and leaf number of the medicinal material under normal growth state in the current growth cycle, respectively.

[0054] Calculate the development status evaluation index ω corresponding to each medicinal material in the current growth cycle f , Among them, a1 and a2 represent the weights of the development status assessment corresponding to the set leaf growth abnormality index and leaf color abnormality index, respectively, and a1+a2=1.

[0055] In a specific embodiment of the present invention, the setting value of a1 is 0.5, and the setting value of a2 is 0.5. The leaf growth abnormality index mainly reflects the growth rate and tillering of the medicinal material leaves, which are usually closely related to the physiological health and overall growth condition of the medicinal material. The leaf color abnormality index mainly focuses on the change in the color of the medicinal material leaves, which is usually related to the photosynthesis, nutrient absorption and disease and pest conditions of the medicinal material. When calculating the development status evaluation index corresponding to each medicinal material in the current growth cycle, the leaf growth abnormality index and the leaf color abnormality index are both important reference indicators.

[0056] The developmental status assessment index corresponding to each medicinal material in the current growth cycle is compared with the developmental status assessment index corresponding to the reference in the current growth cycle. If the developmental status assessment index corresponding to a medicinal material in the current growth cycle is less than the developmental status assessment index corresponding to the reference in the current growth cycle, it indicates that the developmental status of the medicinal material in the current growth cycle is abnormal; otherwise, it indicates that the developmental status of the medicinal material in the current growth cycle is normal.

[0057] The medicinal material growth environment control module is used to record medicinal materials with abnormal development status as target medicinal materials, extract the soil conductivity of each target medicinal material in the current growth cycle, confirm the cause of the abnormal development of each target medicinal material in the current growth cycle, and control the medicinal material growth environment according to the cause of the abnormal development.

[0058] It should be noted that the soil conductivity of each target medicinal material in the current growth cycle is collected by a soil detector.

[0059] In a specific embodiment of the present invention, the specific method of confirming the cause of the abnormal development of each target medicinal material in the current growth cycle is: establishing a diagnosis model for the cause of the abnormal development of each target medicinal material in the current growth cycle, and outputting the diagnosis result of the cause of the abnormal development, wherein the diagnosis model for the cause of the abnormal development is expressed as: Among them, θ′ and They respectively represent the reference leaf growth abnormality index and leaf color abnormality index.

[0060] In a specific embodiment of the present invention, the specific process of regulating the growth environment of medicinal materials according to the cause of developmental abnormalities is as follows: if the cause of the developmental abnormality of a target medicinal material in the current growth cycle is abnormal leaf growth, the leaf growth abnormality index corresponding to the target medicinal material in the current growth cycle is recorded as θ, and the appropriate growth light supplementation time corresponding to the unit leaf growth deviation is extracted from the database, recorded as T0, the plant growth light is turned on, and (θ-θ′)*T0 is used as the supplementary light time corresponding to the plant growth light of the target medicinal material in the current growth cycle.

[0061] It should be noted that light is the main source of energy for photosynthesis of medicinal materials. Light intensity directly affects the photosynthetic rate of medicinal material leaves, which in turn affects their growth rate and biomass accumulation. Adequate light can promote photosynthesis of medicinal material leaves, increase the chlorophyll content and accumulation of photosynthetic products in the leaves, and thus enhance the growth of the leaves. Therefore, when the leaves of medicinal materials grow abnormally, it means that the photosynthesis of the medicinal materials is insufficient, and it is necessary to increase the light duration of the medicinal materials to enhance the growth of the leaves.

[0062] If the cause of abnormal development of a target medicinal material in the current growth cycle is abnormal leaf color, the soil conductivity of the target medicinal material in the current growth cycle is extracted and recorded as σ. This indicates that the abnormal leaf color of the target medicinal material in the current growth cycle is caused by other reasons. This indicates that the abnormal leaf color of the target medicinal material in the current growth cycle is caused by soil conductivity, and feedback is given, where [σ1, σ2] represents the suitable soil conductivity range for the medicinal material in the current growth cycle.

[0063] It should be noted that soil conductivity is an indicator of the concentration of soluble salt ions in the soil. When the soil conductivity is high, it usually means that the content of soluble salt in the soil is also relatively high. In a high-salt environment, the absorption of nutrients by medicinal leaves may be inhibited, especially the lack of key nutrients such as nitrogen, phosphorus, and potassium, which will directly affect the chlorophyll synthesis and photosynthesis efficiency of the leaves, causing the leaves to become lighter or yellower. Therefore, when the color of the leaves of the medicinal material is abnormal, it means that the concentration of soluble salt ions in the soil of the medicinal material is high, so the soil conductivity needs to be adjusted.

[0064] If the cause of the abnormal development of a target medicinal material in the current growth cycle is a comprehensive abnormality, the leaf growth abnormality index corresponding to the target medicinal material in the current growth cycle is recorded as θ1, the plant growth lamp is turned on, and (θ1-θ′)*T0 is used as the corresponding fill light duration of the plant growth lamp for the target medicinal material in the current growth cycle, and the soil conductivity of the target medicinal material in the current growth cycle is extracted and recorded as σ′. This indicates that the abnormal leaf color of the target medicinal material in the current growth cycle is caused by other reasons. This indicates that the abnormal leaf color of the target medicinal material in the current growth cycle is caused by soil conductivity, and feedback is given.

[0065] The embodiments of the present invention confirm the cause of abnormal development of medicinal materials by combining the growth and development of the medicinal materials themselves during the growth cycle, thereby regulating the growth environment of the medicinal materials according to the cause of the abnormal development, paying close attention to the growth and development of the medicinal materials during the growth cycle, promptly identifying and handling developmental abnormalities, and formulating scientific growth environment regulation strategies based on the growth needs and sensitivities of the medicinal materials. By accurately regulating and optimizing the planting environment, the yield and quality of the medicinal materials can be improved, the risk of pests and diseases can be reduced, and the effective use of resources and sustainable development of the environment can be achieved.

[0066] The database is used to store ventilation time and humidification time corresponding to unit humidity deviation, heating time and heat dissipation time corresponding to unit temperature deviation, leaf color set corresponding to normal development of medicinal materials in the current growth cycle, and appropriate growth light supplementation time corresponding to unit leaf growth deviation. The data sources in the database of this embodiment are shown in Table 1.
