Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
In the related art, most greenhouse curtain mechanisms, such as heat preservation curtain mechanisms, are manually adjusted in the unfolded and folded states by greenhouse managers according to the temperature conditions inside and outside the greenhouse, and the technical defects include that on one hand, the growth environment of the greenhouse can not be precisely and intelligently controlled according to the habit characteristics of plants in different planting areas, and on the other hand, the cost of consumed manpower and material resources is increased along with the expansion of the scale of the greenhouse.
The embodiment of the disclosure provides a greenhouse curtain system and a greenhouse, so that the intellectualization and the precision of the management and control of the internal environment of the greenhouse are improved. The greenhouse curtain system is applied to a greenhouse comprising a plurality of planting areas, the specific construction form of the greenhouse is not limited, and the greenhouse can be a dome type greenhouse, a flat top type greenhouse or a tip type greenhouse, and the like, and can be a thin film greenhouse, a glass greenhouse or a plastic board greenhouse, and the like. In addition, the specific application scenario of the greenhouse is not limited, and for example, the greenhouse can be a vegetable cultivation greenhouse, a flower cultivation greenhouse, an ornamental greenhouse, or a test greenhouse. The present disclosure is also not particularly limited with respect to the geographical, seasonal and environmental conditions to which the greenhouse is applied.
As shown in fig. 1 and 2, some embodiments of the present disclosure provide a greenhouse curtain system 100 that mainly includes: a plurality of heat-insulating curtain mechanisms 101, a plurality of sun-shading curtain mechanisms 102, an outdoor temperature monitoring device 103, an indoor temperature monitoring device 104, an outdoor illumination monitoring device 105, and a control device 106. Therein, the outdoor temperature monitoring device 103 is configured to monitor the ambient temperature outside the greenhouse 300, the indoor temperature monitoring device 104 is configured to monitor the ambient temperature inside the greenhouse 300, and the outdoor illumination monitoring device 105 is configured to monitor the illumination intensity outside the greenhouse 300. The control device 106 is electrically and/or communicatively connected to the outdoor temperature monitoring device 103, the indoor temperature monitoring device 104, the outdoor illumination monitoring device 105, the plurality of heat-insulating curtain mechanisms 101, and the plurality of sunshade curtain mechanisms 102, respectively, and is configured to control the opening degree of each heat-insulating curtain mechanism 101 according to the ambient temperature outside the greenhouse 300 and the ambient temperature inside the greenhouse 300, and to control the opening degree of each sunshade curtain mechanism 102 according to the intensity of illumination outside the greenhouse 300. The "opening degree" herein means a ratio of an expanded area of the curtain to an area of the curtain when the curtain is completely expanded, for example, the opening degree is 0,5%,10%,15%, 82308230, 100%, the curtain is in a closed state when the opening degree of the curtain is 0, and the curtain is in a completely expanded state when the opening degree of the curtain is 100%.
It is to be noted that "communication connection" here and hereinafter includes wired communication connection as well as wireless communication connection. The greenhouse curtain system of the present application is particularly suitable for large-area (e.g., several tens of hectares or more) greenhouse clusters, and as a preferred embodiment, the control device 106 of the present application receives input signals from the outdoor temperature monitoring device 103, the indoor temperature monitoring device 104, the outdoor illumination monitoring device 105, the plurality of heat-insulating curtain mechanisms 101, and the plurality of sunshade curtain mechanisms 102 by being connected in wireless communication with the outdoor temperature monitoring device 103, the indoor temperature monitoring device 104, the outdoor illumination monitoring device 105, the plurality of heat-insulating curtain mechanisms 101, and the plurality of sunshade curtain mechanisms 102, and transmits control instructions to the outdoor temperature monitoring device 103, the indoor temperature monitoring device 104, the outdoor illumination monitoring device 105, the plurality of heat-insulating curtain mechanisms 101, and the plurality of sunshade curtain mechanisms 102. Thus, it is possible to save the cost of laying lines for the control devices 106 to receive external inputs and issue control instructions in a large-area greenhouse cluster, and since these complex line laying are omitted, the complexity of installation and deployment of the system is further simplified, the facility occupation space in the greenhouse is saved, and the effective use area of the temperature is increased.
As shown in FIG. 2, the heat-insulating curtain mechanism 101 can maintain the temperature inside the greenhouse 300, so that the plants inside the greenhouse 300 can resist the low temperature outside, and the space inside the greenhouse 300 that needs to be heated can be effectively reduced. The sunshade screen mechanism 102 can be used to shade the sun during periods of excessive light, thereby keeping the plants and the greenhouse cool. With continued reference to fig. 2, in some embodiments, the plurality of thermal insulation curtain mechanisms 101 includes a plurality of top thermal insulation curtain mechanisms 101a and a plurality of side thermal insulation curtain mechanisms 101b disposed inside the greenhouse 300, and the plurality of sunshade curtain mechanisms 102 can be disposed inside the greenhouse 300 or outside the greenhouse 300 (in the embodiment shown, outside the greenhouse 300). In consideration of the heat insulation effect of the greenhouse 300, the heat insulation curtains of the plurality of heat insulation curtain mechanisms 101 cover most of the area of the greenhouse 300 when being completely unfolded, and the coverage range of the sun shade curtains of the plurality of sun shade curtain mechanisms 102 when being completely unfolded can be specifically designed according to the lighting requirement degree of the plants in different planting areas 30, the lighting angle of the different planting areas 30 and the like, for example, the sun shade curtain mechanisms 102 are not required in some planting areas.
The heat preservation curtain mechanism 101 and the sunshade curtain mechanism 102 are matched for use, so that a better and favorable growing environment can be provided for planting plants by combining the climate characteristics of the region where the greenhouse 300 is located and the habit characteristics of the plants planted in the greenhouse, and the cost of public facilities such as water, electricity and the like can be greatly reduced.
The specific structural form of the heat insulating curtain mechanism 101 is not limited in this disclosure, and may be, for example, a roll type heat insulating curtain mechanism or a folding type heat insulating curtain mechanism, where the roll type heat insulating curtain mechanism folds the heat insulating curtain by winding, and the folding type heat insulating curtain mechanism folds the heat insulating curtain by folding. The specific structural form of the sunshade screen mechanism 102 is not limited in the present disclosure, for example, the sunshade screen mechanism 102 may be a roller sunshade screen mechanism, a folding sunshade screen mechanism, or a louver sunshade screen mechanism, wherein the roller sunshade screen mechanism adjusts the opening degree of the sunshade screen by rolling, the folding sunshade screen mechanism adjusts the opening degree of the sunshade screen by folding, and the louver sunshade screen mechanism adjusts the opening degree of the sunshade screen by rotating the louver. The control device 106 outputs a control signal to the respective driving devices (e.g., driving motors) of the heat-insulating curtain mechanism 101 and the sunshade curtain mechanism 102, and then precisely controls the opening and closing states of the curtains by the driving mechanisms (e.g., gear transmission mechanisms).
The outdoor temperature monitoring device 103 and the indoor temperature monitoring device 104 each include, for example, one or more temperature sensors (or may be a temperature/humidity sensor that integrates a temperature monitoring function and a humidity monitoring function), and the specific arrangement position is not limited to that shown in fig. 2. The outdoor lighting monitoring device 105 includes, for example, one or more lighting sensors, and the specific location is not limited to that shown in fig. 2.
In the embodiment of the present disclosure, write in the main control board of controlgear 106 through with some reasonable parameter threshold values, controlgear 106 alright according to the outside ambient temperature of greenhouse 300 and the ambient temperature in the greenhouse 300, the aperture of every heat preservation curtain mechanism 101 of automatic control, and according to the aperture of every sunshade curtain mechanism 102 of the outside illumination intensity automatic control of greenhouse 300, thereby the intelligent degree and the degree of accuracy of greenhouse internal environment management and control have been promoted, make the management and control of greenhouse internal environment intelligent, high efficiency, rationalization, intensification and integration, can also greatly reduced the management and operation cost of greenhouse when improving the greenhouse output benefit.
In some embodiments, the control device 106 is configured to control the at least one heat-retaining curtain mechanism 101 to intermittently adjust the opening, e.g., increase or decrease the opening in steps at set time intervals, when the temperature difference between the inside and outside environment of the greenhouse 300 is greater than a temperature difference threshold. For example, when the temperature difference between the inside and outside environment of the greenhouse 300 is greater than the temperature difference threshold, the heat-insulating curtain mechanism 101 intermittently adjusts the opening degree by reducing the opening degree by 20% every 10 minutes until the temperature difference is completely closed. Therefore, the adverse effect of too fast temperature change in the greenhouse on the growth and development of plants can be reduced as much as possible.
In some embodiments, the control device 106 is configured to control the plurality of heat-retaining curtain mechanisms 101 to sequentially adjust the opening degrees in a preset order based on the ambient temperature outside the greenhouse 300 and the ambient temperature inside the greenhouse 300. For example, when the ambient temperature outside the greenhouse 300 suddenly drops and the temperature difference between the inside and outside of the greenhouse 300 is greater than the temperature difference threshold, the control device 106 may first deploy one or some of the heat-insulating curtain mechanisms 101 near the window, and then deploy the remaining heat-insulating curtain mechanisms 101, so as to provide heat-insulating measures for the greenhouse in time, and improve the heat-insulating control effect and efficiency.
It should be noted that the control strategy of the control device 106 according to the embodiment of the present disclosure is not particularly limited, and may be flexibly adjusted according to the region, season and environmental conditions of the greenhouse, for example, one or more of the above control strategies may be included. The following is a specific application example of some embodiments of the present disclosure.
For example, cherry tomatoes are warm-loving and bright-loving vegetables, and require higher temperature for growth and development than ordinary tomatoes, and under general conditions, the suitable environmental temperature for cultivating cherry tomatoes is not lower than 10 ℃ at night, 20-25 ℃ in the daytime and not higher than 35 ℃ at most. When coming night, controlgear 106 can judge that coming night according to the illumination intensity outside the greenhouse, if the ambient temperature outside the greenhouse drops to nearly 10 ℃ (for example to 12 ℃), controlgear can each heat preservation curtain mechanism of automatic control expand to form basic confined insulation construction, keep warm to greenhouse internal environment. After the day, the control device 106 may determine the day according to the illumination intensity outside the greenhouse, and if the ambient temperature outside the greenhouse has risen to a suitable temperature (for example, to 10 ℃ or above), the control device may automatically control the sunshade curtain mechanism of the cherry and tomato planting area to fold and control the heat-insulating curtain mechanism to intermittently and slowly fold step by step according to the ambient temperature outside the greenhouse and the ambient temperature inside the greenhouse, so that adverse effects of temperature changes on plant growth and development may be minimized. Greenhouse managers can flexibly set related parameter thresholds according to energy cost consumed by greenhouse heat preservation at night. For example, the lower limit of the environment temperature threshold outside the greenhouse corresponding to the expansion of the heat-insulating curtain mechanism is set to be slightly higher than the lower limit of the suitable growth temperature of the plants, so that when the temperature is continuously reduced, the control equipment can properly control the expansion of the heat-insulating curtain mechanism in advance, the temperature of the greenhouse can be effectively maintained, and the investment of public energy can be saved.
For example, the mushrooms are vegetables like a Chinese character yin, the control equipment controls the heat-preservation curtain mechanism of the planting area where the mushrooms are located to be folded in the daytime, and when the light intensity outside the greenhouse exceeds the light intensity threshold value, the control equipment can properly increase the opening degree of the shade curtain mechanism of the mushroom planting area, namely the unfolding area of the shade curtain is increased. In the afternoon or in the evening, when the illumination intensity outside the greenhouse is no longer higher than the illumination intensity threshold value, the control device can fold the shading curtain mechanism, for example, the opening degree is adjusted to be the minimum, so as to meet the illumination requirement of the plants.
In some embodiments, at least one top heat-preservation curtain mechanism, at least one side heat-preservation curtain mechanism and at least one sunshade curtain mechanism are configured for each planting area, so that the opening degree of the heat-preservation curtain mechanism and the opening degree of the sunshade curtain mechanism of the planting area can be controlled in a targeted manner according to the habit characteristics of the plants planted in the planting area and the lighting characteristics of the planting area, and therefore more suitable ambient temperature and illumination intensity can be provided for the plants in the planting area.
As shown in fig. 2 and 3, in some embodiments of the present disclosure, the greenhouse curtain system 100 further includes, on the basis of the previously described embodiments: an indoor illumination monitoring device 108 configured to monitor illumination intensity within the greenhouse 300, and at least one fill light device 109; the control device 106 is further electrically and/or communicatively connected to the indoor illumination monitoring device 108 and the at least one light supplement device 109, and is configured to control an on/off state of each light supplement device 109 according to the illumination intensity in the greenhouse 300, where the on/off state includes, for example, at least one of: the light supplement device 109 is turned on and off, the illumination intensity of the light supplement device 109 is adjusted when the light supplement device 109 is turned on, and the color temperature of the light supplement device 109 is adjusted when the light supplement device 109 is turned on. The fill-in light device 109 includes one or more fill-in lights, such as an LED fill-in light or a xenon fill-in light with a fixed illumination intensity and a fixed color temperature, or an LED fill-in light or a xenon fill-in light with an adjustable illumination intensity and/or color temperature.
When the outside light of the greenhouse 300 is insufficient, the amount of light required by the plants is not enough, or the illumination time for the plants needs to be increased in order to improve the output benefit of the greenhouse 300, or the plants have special requirements for light with a certain wavelength, some light supplement devices 109 can be turned on as needed, or the illumination intensity and/or the color temperature of the light supplement devices 109 can be adjusted as needed. The scheme design of the embodiment can meet the constant or higher requirement of the plants in different planting areas 30 on illumination, thereby improving the output benefit of the greenhouse 300 and being beneficial to culturing more excellent varieties.
In the embodiment of the present disclosure, the control device 106 is, for example, a control electrical cabinet including a main control panel, a display screen and an interactive operation device 1061, where the display screen and the interactive operation device 1061 may be integrally provided, for example, integrated into a touch display operation screen, and the interactive operation device 1061 may also be provided independently from the display screen, for example, the interactive operation device 1061 is an operation panel including a plurality of physical keys.
As shown in fig. 3, in one embodiment of the present disclosure, an interoperating device 1061 (e.g., a touch display operation screen) is configured to provide: the selection input of the first automatic control mode and the second automatic control mode of the plurality of heat-insulating curtain mechanisms 101, the selection input of the third automatic control mode and the fourth automatic control mode of the plurality of sunshade curtain mechanisms 102, the selection input of the fifth automatic control mode and the sixth automatic control mode of the at least one light supplement device 109, the selection input of the manual control mode, and the input of the control information of the plurality of heat-insulating curtain mechanisms 101 and the plurality of sunshade curtain mechanisms 102. That is, the greenhouse manager can perform at least the selection of the above control mode and the input of information by operating the interactive operation device 1061.
Based on the selection results of the above plurality of control modes, the main control board of the control device 106 is written with a corresponding program, and the control device 106 is configured to:
1. and responding to the received selection instruction corresponding to the first automatic control mode, and controlling the opening degree of each heat-preservation curtain mechanism according to the ambient temperature outside the greenhouse and the ambient temperature inside the greenhouse. For example, when the ambient temperature outside the greenhouse is reduced to below 10 ℃, each heat-preservation curtain mechanism is controlled to be unfolded; when the environment temperature outside the greenhouse is raised to 10 ℃ or above, each heat-preservation curtain mechanism is controlled to be folded.
2. And in response to receiving a selection instruction corresponding to the second automatic control mode, controlling each heat preservation curtain mechanism to be unfolded within at least one first preset time period and to be folded outside the at least one first preset time period. For example, each heat preservation curtain mechanism is controlled to be folded at the time periods from 06.
3. And responding to the received selection instruction corresponding to the third automatic control mode, and controlling the opening degree of each sunshade curtain mechanism according to the illumination intensity outside the greenhouse. For example, when the illumination intensity outside the greenhouse reaches a first illumination intensity threshold value, the opening degree of a sunshade curtain mechanism of a certain heliophilous plant growing area is controlled to be 10%; when the illumination intensity outside the greenhouse continues to increase and reaches a second illumination intensity threshold value, controlling the opening degree of a sunshade curtain mechanism of the planting area to be 20%; when the illumination intensity outside the greenhouse continues to increase and reaches a third illumination intensity threshold value, controlling the opening degree of a sunshade curtain mechanism of the planting area to be 30%; 8230and so on.

5. And responding to the received selection instruction corresponding to the fifth automatic control mode, and controlling the on-off state of each light supplementing device according to the illumination intensity in the greenhouse. For example, in the daytime of the winter day without sunlight, when the illumination intensity in the greenhouse is lower than the second illumination intensity threshold value, the one or some light supplement devices are controlled to be started; when the weather is good and the illumination quantity is increased, the illumination intensity in the greenhouse is no longer lower than the second illumination intensity threshold value, and then the light supplementing equipment is controlled to be closed.
6. And in response to receiving a selection instruction corresponding to the sixth automatic control mode, controlling each light supplementing device to be in a corresponding preset on-off state within at least one third preset time period. For example, for a planting area needing light supplement, the light supplement device is controlled to be turned on at 17-00-19. For example, for a planting area which does not need light supplement, the light supplement equipment is controlled to be closed all day long. For example, for a planting area of a certain test variety, the ultraviolet light supplement equipment is controlled to be started from 22 to 00 per day.
7.
