Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In a first aspect of the present application, a method for controlling a plant growth environment is provided. Referring to fig. 1, in one embodiment, the method includes steps S300 to S700.
Step S300: and acquiring the growth parameters of the maintained plants.
Wherein the plant to be maintained can be medicinal materials, flowers, vegetables, fruits, etc. The growth parameters of the maintained plants comprise illumination parameters, soil parameters, environmental temperature and environmental humidity acquired by the parameter acquisition equipment. Different growth parameters are acquired by different parameter acquisition equipment respectively, and the acquisition equipment of the same growth parameter is not unique. For example, the illumination parameters may include illumination intensity, PAR values, and the like, which are acquired by an illuminometer and a light quantum sensor, and a plurality of illuminometers may be set at different positions to acquire the illumination intensity at the corresponding position, and the light quantum sensors may be set for different plants to acquire the PAR values. For another example, the soil parameters may include soil humidity, soil temperature, soil pH, soil EC value, and the like, which are respectively acquired by corresponding sensors, the soil may be divided into different layers according to depth, and the sensors are respectively disposed on each layer to acquire the soil parameters of the corresponding layer. Specifically, the mode for the control device to acquire the growth parameters of the plant to be maintained may be actively reading the sampling information of the parameter acquisition device, or passively receiving the sampling information sent by the parameter acquisition device, and in short, the mode for the control device to acquire the growth parameters of the plant to be maintained is not limited.
Step S500: and judging whether each growth parameter is within the corresponding preset threshold range of the maintained plant.
As described above, the growth parameters of the maintained plants include the illumination parameters, the soil parameters, the ambient temperature and the ambient humidity, and the data forms of different growth parameters are different, so that the corresponding preset threshold ranges are different. For a specific plant to be maintained, each specific growth parameter has a corresponding preset threshold range, and when all the growth parameters meet the corresponding preset threshold ranges, the current growth environment is appropriate.
And after the control equipment acquires the growth parameters of the maintained plants, the growth parameters are respectively compared with the corresponding preset threshold value ranges, and whether the growth parameters are in the corresponding preset threshold value ranges of the maintained plants is judged. Specifically, the priority may be set according to the importance and relevance of each growth parameter, and then the judgment of different growth parameters may be performed in sequence according to the preset priority, or all the growth parameters may be judged synchronously. In short, the present embodiment does not limit the determination sequence of whether each growth parameter is within the corresponding preset threshold range.
Step S700: and when the growth parameters are not in the corresponding preset threshold range of the plant to be maintained, adjusting the working parameters of the associated equipment according to the size relation between the growth parameters and the corresponding preset threshold range.
Each acquisition device of the growth parameters is provided with a corresponding associated device, and the growth parameters can be changed along with the change of the working parameters of the corresponding associated devices. And adjusting the working parameters of the associated equipment, including turning on or off the associated equipment, and performing mode switching or parameter adjustment on the associated equipment. Specifically, when the growth parameters are not within the corresponding preset threshold range of the plant to be maintained, it is indicated that the current environment is not favorable for the growth of the plant to be maintained, and at this time, the working parameters of the associated equipment are adjusted according to the size relationship between the growth parameters and the corresponding preset threshold range, so as to maintain the proper plant growth environment. Further, if each growth parameter is within the corresponding preset threshold range, which indicates that the current environment is appropriate, the current working parameters of the associated device are kept unchanged.
In addition, the control equipment can also send the current growth parameters of the maintained plants and the current working parameters of the associated equipment to the terminal, so that the staff at the terminal can conveniently monitor the growth environment of the plants in real time. Furthermore, if the corresponding growth parameter is not adjusted to the preset threshold range of the plant to be maintained after the control device adjusts the working parameter of the associated device and a preset time threshold passes, it indicates that the control system may malfunction. At the moment, the control equipment controls the alarm equipment to send alarm information, and meanwhile, an abnormity prompt is sent to the terminal to remind a worker to perform abnormity processing in time.
The plant growth environment control method comprises the steps of firstly obtaining growth parameters of plants to be maintained, then judging whether the growth parameters are in the corresponding preset threshold range of the plants to be maintained, and when the growth parameters are not in the corresponding preset threshold range of the plants to be maintained, adjusting the working parameters of the associated equipment according to the size relation between the growth parameters and the corresponding preset threshold range. The whole control process is automatically carried out without manual participation, and the work efficiency is favorably improved.
In an embodiment, referring to fig. 2, before the step S500, the method further includes a step S400: and acquiring a preset threshold range.
For a specific plant to be maintained, each specific growth parameter has a corresponding preset threshold range, and when all the growth parameters meet the corresponding preset threshold ranges, the current growth environment is appropriate. Specifically, the preset threshold ranges of different plants can be stored in the storage device or the cloud server, and the control device acquires the corresponding preset threshold ranges from the storage device or the cloud server through data interaction according to the types of the plants to be maintained at present.
In the above embodiment, before determining whether each growth parameter is within the corresponding preset threshold range of the maintained plant, the control device obtains the corresponding preset threshold range according to the type of the current maintained plant, so that the control effect of the plant growth environment control method can be improved.
In one embodiment, the associated devices include a lighting device and a temperature adjustment device, and with continued reference to fig. 2, before step S300, step S100 and step S200 are further included.
Step S100: and acquiring the plant temperature of the maintained plant.
The lighting device comprises a lighting fixture and related circuits thereof. The lighting fixture may be an LED (Light Emitting Diode) lamp or an HID (High intensity Discharge) lamp. The LED lamp has the advantages of high efficiency, energy conservation, safety, long service life, small size, clear light and the like, and is beneficial to energy conservation and environmental protection. And according to the type of the plant to be maintained, the LED lamps with different light-emitting wavelengths can be correspondingly arranged so as to improve the PAR value. The HID lamp has a white light source and is the most commonly used plant growth lamp. Its luminous spectrum is similar to that of the sun and has high lumen efficiency. The temperature regulating device may be an air conditioner or a fan. In order to make all parts of the plant to be cured can be fully illuminated, two or more than two illuminating lamps can be arranged.
Specifically, the plant temperature of the plant to be maintained may be leaf surface temperature, stem temperature or other part temperature of the plant to be maintained. The temperature of the plant to be maintained is not equal to the ambient temperature, and is related to not only the ambient temperature but also the heat exchange between the plant to be maintained and the environment. Taking the leaf surface temperature as an example, when the ultraviolet radiation is strong, the leaf surface temperature is generally higher than the ambient temperature; and at night, the leaf surface temperature is lower than the ambient temperature. Because lighting apparatus can be accompanied with thermal giving off when bringing the light, will superpose ambient temperature and influence the plant temperature by the maintenance plant jointly, consequently, can regard as the collection position of plant temperature by the position that the maintenance plant is closest to lighting apparatus. Similarly, the mode of acquiring the plant temperature of the plant to be maintained by the control device may be actively reading the sampling information of the parameter acquisition device, or passively receiving the sampling information sent by the parameter acquisition device, and in short, the mode of acquiring the plant temperature of the plant to be maintained by the control device is not limited.
Step S200: when the plant temperature is greater than or equal to the preset plant temperature threshold value, the lighting equipment is turned off, and the temperature adjusting equipment is adjusted to be in a refrigeration working mode.
Specifically, plant transpiration lowers the plant temperature, and thus, when the plant temperature of the plant to be maintained rises, the plant temperature is accompanied by an increase in transpiration. When the plant temperature reaches a preset plant temperature threshold value, the growth condition of the plant is influenced by water evaporation brought by transpiration. At this moment, the control equipment closes the lighting equipment, and adjusts the temperature adjusting equipment to the refrigeration mode of operation, reduces the heat radiation of lighting equipment on the one hand, and on the other hand accelerates the heat exchange of air and the plant of being maintained to reduce the plant temperature.
It is understood that when the growing environment of the plant to be maintained is suitable, the plant temperature is always less than the preset plant temperature threshold. When the growth parameters of the maintained plants are not in the corresponding preset threshold value range, the temperature of the plants is not necessarily greater than or equal to the preset temperature threshold value of the plants. The plant temperature of the plant to be maintained is obtained before the growth parameters of the plant to be maintained are obtained, so that the problem that the plant temperature is too high due to extreme conditions is avoided, and the healthy growth of the plant to be maintained is further ensured.
In one embodiment, the illumination parameter is a PAR value, the associated device comprises a lighting device, please refer to fig. 3, and step S700 comprises step S720 and step S740.
Step S720: and determining the difference value of the PAR value and the optimal PAR value according to the magnitude relation between the PAR value and the optimal PAR value.
The PAR value is a radiation value of a spectral component effective for photosynthesis of a plant in illumination radiation, and is a basic energy source for forming biomass, and directly influences growth, development, yield and quality of the plant. The optimum PAR value of the plant to be maintained is dependent on the specific type of plant to be maintained. The optimal PAR values corresponding to different types of plants to be maintained can be stored in the storage device or the cloud server, and the control device acquires the corresponding optimal PAR values from the storage device or the cloud server through data interaction according to the types of the plants to be maintained at present.
According to different metering principles, PAR can use illuminance (lx), light radiance (W/m)2) And the light quantum flux density (μmol/m)2s) is measured. In one embodiment, the PAR value is acquired by a PAR value sensor based on optical quantum effects. Furthermore, the distance between the PAR value sensor and the plant to be maintained is smaller than the preset distance and is within the height range of the plant to be maintained, so that the accuracy of data acquisition is improved. And according to the magnitude relation between the acquired PAR value and the optimal PAR value, subtracting the acquired PAR value and the optimal PAR value to determine the difference value between the PAR value and the optimal PAR value.
Step S740: and when the difference value exceeds a preset difference value range, adjusting the luminous power of the lighting equipment according to the difference value and the relation between the PAR value and the luminous power of the lighting equipment.
The PAR value is proportional to the luminous power of the lighting device, and thus, the PAR value of the output light can be controlled by adjusting the luminous power of the lighting device. When the difference value between the acquired PAR value and the optimal PAR value exceeds the preset difference value range, the effective radiation provided by the lighting equipment cannot meet the radiation required by the photosynthesis of the plant to be maintained, and if the difference value is not adjusted in time, the growth and development of the plant to be maintained can be influenced. At the moment, the control equipment adjusts the luminous power of the lighting equipment according to the difference value between the acquired PAR value and the optimal PAR value and the relation between the PAR value and the luminous power of the lighting equipment, so that the PAR value is close to the optimal PAR value as much as possible, and the good growth condition of the maintained plant is ensured.
In an embodiment, please continue to refer to fig. 3, before step S740, step S730 is further included: the relation between the PAR value and the luminous power of the lighting device is obtained.
Specifically, the change relationship of the PAR value of the measurement position along with the luminous power of the lighting device can be obtained through experiments, the change relationship is stored in the cloud server or the storage device, and the control device acquires the corresponding preset threshold range from the storage device or the cloud server through data interaction. It can be understood that when the number of the plants to be maintained is two or more than two, a plurality of PAR value acquisition devices can be correspondingly arranged, the acquisition devices at different acquisition positions are numbered, and then the control device acquires the relation between the corresponding PAR value and the luminous power of the lighting device according to the number of the acquisition devices.
In the above embodiment, the luminous power of the lighting device is automatically adjusted according to the acquired PAR value, so that the PAR value is as close to the optimal PAR value as possible, the growth condition of the plant to be maintained can be ensured to be good, and the quality of the plant to be maintained is improved.
In one embodiment, the associated devices include a temperature adjustment device and a lighting device, please refer to fig. 4, step S700 includes step S750 and step S760.
Step S750: and adjusting the working parameters of the temperature adjusting equipment according to the size relation between the environment temperature and the preset environment temperature threshold range.
The temperature regulating device may be an air conditioner or a fan having both cooling and heating effects, such as an industrial air conditioner. Specifically, when the ambient temperature is higher than the upper limit of the preset ambient temperature threshold range, the control device controls the temperature adjusting device to switch to the cooling mode; and when the ambient temperature is lower than the lower limit of the preset ambient temperature threshold range, the control equipment controls the temperature regulating equipment to be switched into the heating mode. Further, according to the difference between the ambient temperature and the preset upper limit or the preset lower limit of the ambient temperature threshold, the working parameters in the corresponding mode can be adjusted to ensure the working efficiency. In addition, the temperature adjusting device can further comprise a heater, and when the ambient temperature is lower than the lower limit of the preset ambient temperature threshold range, the control device can also control the heater to be started at the same time so as to improve the heating effect.
Step S760: and when the ambient temperature is greater than or equal to the upper limit of the preset ambient temperature threshold range, turning off the lighting device.
Specifically, the lighting device can bring certain heat radiation while providing illumination, and when the ambient temperature is greater than or equal to the upper limit of the preset ambient temperature threshold range, the lighting device is turned off, so that the further rise of the ambient temperature caused by the heat radiation of the lighting device can be avoided.
In the above embodiment, the control device automatically adjusts the working parameters of the temperature adjusting device and the lighting device according to the collected ambient temperature, and the whole control process does not need manual participation, thereby being beneficial to improving the working efficiency.
In one embodiment, the soil parameters include soil moisture, soil pH and soil EC, the associated device includes an irrigation device, step S700 includes step S770: and adjusting the working parameters of the irrigation equipment according to the size relationship between the soil humidity and the preset soil humidity threshold range, the size relationship between the soil pH value and the preset soil pH value threshold range and the size relationship between the soil EC value and the preset soil EC value threshold range.
Wherein, the pH value of the soil refers to the concentration of hydrogen ions and hydroxyl ions in the soil solution, and is used for representing the pH value of the soil. Neutral soil with pH of 6.5-7.5; acid soil below 6.5; above 7.5 is alkaline soil, most plants are difficult to grow at pH >9.0 or < 2.5. Plants can grow normally over a wide range, but each plant has its own appropriate pH, i.e. a soil pH threshold range. When the pH value of the soil exceeds the pH value threshold range of the soil, the growth of the maintained plants is hindered and the development is retarded along with the increase or decrease of the pH value. Specifically, the pH value of the soil can be improved by adjusting the working parameters of the irrigation equipment. Specifically, when the soil is too acidic, plant ash or lime can be added into irrigation water to form a suspension rich in hydroxide ions to irrigate the soil so as to neutralize the hydrogen ions; when the soil is too alkaline, an aqueous solution of ferrous sulfate or aluminum sulfate may be irrigated to increase the soil acidity. Furthermore, the concentration of the solution in the irrigation water can be adjusted according to the difference value between the pH value of the soil and the upper limit or the lower limit of the threshold range of the pH value of the soil, so that the improvement effect of the pH value of the soil is improved.
The soil EC value refers to the soil conductivity and can be used for characterizing the concentration of soluble salts in a soil solution. The soil EC values are expressed in units of mS/cm or mmhos/cm. Normal soil EC values range between 1-4mmhos/cm (or mS/cm). When the EC value of the soil is too high, reverse osmosis pressure can be formed, water in root systems is replaced, and root tips are browned or dried. Meanwhile, the occurrence probability of root rot caused by germs is increased by overhigh soil EC value. Soil EC values can be adjusted by adjusting irrigation equipment. Specifically, the concentration of inorganic salt in irrigation water is adjusted through the soil EC value obtained through real-time monitoring, and the overhigh soil EC value is avoided.
The soil moisture is the soil moisture content and is used to indicate the dryness of the soil. Soil moisture determines the moisture supply of the plant being maintained. The soil humidity is too low, soil drought is formed, the photosynthesis can not be normally carried out, and the yield and the quality of the maintained plants are reduced; severe water shortage will lead to wilting and death of the maintained plants. Soil humidity is too high, worsens soil air permeability, influences the activity of soil microorganism, makes the life activities such as breathing, growth of being maintained the plant root system receive the hindrance to influence the normal growth of being maintained the plant overground part, cause vain, lodging, disease to breed etc.. Therefore, the working parameters of the irrigation equipment are adjusted according to the relation between the soil humidity and the preset soil humidity threshold value range, and the soil humidity can be kept appropriate. Specifically, the flow of irrigation water can be adjusted through the soil humidity obtained through real-time monitoring, so that overhigh soil humidity is avoided; when the soil humidity is too high, irrigation should be stopped and drainage should be enhanced to reduce the soil humidity.
Furthermore, when the soil parameters are collected and controlled, the soil can be divided into different layers according to the depth, and collecting equipment and irrigation equipment are respectively arranged on each layer to correspondingly control the soil parameters of each layer of soil. In addition, the soil pH value and the soil EC value can be obtained before the plants to be maintained are planted, soil improvement can be carried out according to the obtained sampling numerical value, the soil pH value threshold range and the soil EC value threshold range of the plants to be maintained, and then planting and cultivation can be carried out on the improved soil.
In the above embodiment, the control device adjusts the working parameters of the irrigation device according to the collected soil parameters, which is beneficial to maintaining the soil parameters within the corresponding preset threshold range and improving the quality of the maintained plants.
In one embodiment, the associated device comprises a humidity adjustment device, and step S700 comprises step S780: and adjusting the working parameters of the humidity adjusting equipment according to the size relation between the environmental humidity and the preset environmental humidity threshold range.
Wherein, the humidity adjusting device comprises a dehumidifier and a humidifier. Specifically, when the ambient humidity is higher than the upper limit of the preset ambient humidity threshold range, the control device starts the dehumidifier and adjusts the working parameters of the dehumidifier according to the difference between the ambient humidity and the upper limit of the ambient humidity threshold range; when the environmental humidity is lower than the lower limit of the preset environmental humidity threshold range, the control device starts the humidifier and adjusts the working parameters of the humidifier according to the difference between the environmental humidity and the lower limit of the environmental humidity threshold range.
In the above embodiment, the control device automatically adjusts the working parameters of the humidity adjusting device according to the collected environmental humidity, and the whole control process does not need manual participation, thereby being beneficial to improving the working efficiency.
It should be understood that although the various steps in the flow charts of fig. 1-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-4 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
