For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] The following Figures 1-4 describes the intelligent monitoring method and intelligent monitoring system for the greenhouse environment of the present invention.

[0034] As Figure 1 shown, the intelligent monitoring method for the greenhouse environment provided by the embodiments of the present invention includes the steps of:

[0035] S100, controlling the monitoring unit of the monitoring device to collect the environmental data inside the greenhouse at a set frequency.

[0036] S200, obtaining the production status information inside the greenhouse.

[0037] S300, if it is determined that the inside of the greenhouse is in a non-planting state according to the production status information, then controlling the monitoring unit to reduce the collection frequency of the environmental data.

[0038] Specifically, the monitoring device is installed in the greenhouse. After initialization, the monitoring unit of the monitoring device collects the environmental data inside the greenhouse at a preset acquisition frequency. The environmental data inside the greenhouse includes, but is not limited to, air environmental data, light environmental data, soil environmental data, etc. The acquisition frequency of each type of environmental data can be simultaneously reduced when it is determined that the inside of the greenhouse is in a non-planting state. Each type of environmental data sets its own independent acquisition frequency according to the monitoring requirements.

[0039] The production status information inside the greenhouse includes planting status, fallow status, and abandoned status. The fallow status and the abandoned status belong to the non-planting state. In the planting state, there are crops in the planting state inside the greenhouse. At this time, the monitoring unit is controlled to collect the environmental data inside the greenhouse at a higher acquisition frequency to intensively monitor the growth environment of the crops. In the fallow status and the abandoned status, there are no crops in the planting state inside the greenhouse. At this time, the monitoring unit is controlled to collect the environmental data inside the greenhouse at a lower acquisition frequency to reduce the power consumption of the monitoring unit.

[0040] The greenhouse environment intelligent monitoring method provided by the embodiments of the present invention controls the data acquisition frequency of the monitoring unit according to the production status information inside the greenhouse. When the inside of the greenhouse is in a non-planting state, the monitoring unit is controlled to reduce the acquisition frequency of the environmental data. By adopting the method of intelligently adjusting the data acquisition frequency, the energy consumption of the monitoring device is saved, and the service life of the monitoring device is extended.

[0041] In some embodiments of the present invention, the environmental data includes image data inside the greenhouse. The obtaining of the production status information inside the greenhouse described in step S200 includes: determining the production status information inside the greenhouse based on the image data. Among them, the monitoring unit includes an image collector, such as a camera. The internal image of the greenhouse is collected by the image collector at a set frequency. After the monitoring device analyzes and processes the image information, it determines whether the inside of the greenhouse is in a planting state or a non-planting state.

[0042] Furthermore, the greenhouse environment intelligent monitoring method provided by some embodiments of the present invention further includes the steps:

[0043] S410, if it is determined that the inside of the greenhouse is in a planting state according to the production status information, then determine the growth stage information of the crops in the planting state based on the image data.

[0044] S420, control the monitoring unit to adjust the acquisition frequency of the environmental data according to the growth stage information.

[0045] Specifically, when the inside of the greenhouse is in the planting state, the data acquisition frequency of the monitoring unit is higher than that in the non-planting state, and the data acquisition frequency is further adjusted according to the growth stage information of the crops inside the greenhouse. For example, the growth stages of the crops include the seedling stage, the growth stage, the flowering stage, and the fruiting stage. The growth stage information characterizes the growth state of the crops. When it is determined based on the image data that the crops are in the seedling stage or the flowering stage, data is acquired at a higher frequency to achieve intensive monitoring of the crops. When it is determined based on the image data that the crops are in the growth stage or the fruiting stage, data is acquired at a lower frequency to save energy while meeting the monitoring requirements.

[0046] In this embodiment, the data acquisition frequency is dynamically and intelligently adjusted according to the growth stage information of the crops. On the basis of reducing the energy consumption of the monitoring device, fine monitoring of the greenhouse environment is achieved, providing effective data support for the management and decision-making of the greenhouse facilities.

[0047] The intelligent greenhouse environment monitoring method provided by some embodiments of the present invention further includes: constructing a growth model of the crops, and the growth model includes the characteristic information of the crops in different growth stages. The growth models of one or more crops are preset in the system. If it is determined according to the production state information that the inside of the greenhouse is in the planting state, then the crop variety in the planting state is determined based on the acquired image data, and the growth model corresponding to the crop variety is called based on the crop variety. Then, based on the growth model, the data acquisition frequency of the monitoring unit for environmental data in different growth stages is adjusted. In this embodiment, the data acquisition frequency is dynamically and intelligently adjusted based on the growth model of the crops, and different data acquisition strategies can be adopted for different crops to achieve fine intelligent monitoring.

[0048] For the construction of the growth model, in some embodiments, the growth model can be constructed based on the empirical data of the crop planting period and preset in the monitoring device. In other embodiments, the growth model is a machine learning model, and the machine learning model is a trained convolutional neural network model, and the crop variety and growth state planted in the greenhouse are identified based on the machine learning model. The pre-training of the model can be completed on the server side, aiming to ensure that the accuracy of the model can reach a certain level, and a large number of images inside the greenhouse facilities are classified and trained.

[0049] When the monitoring device is initialized, the monitoring device can directly retrieve the growth model corresponding to the known crop types in the greenhouse. Or, the crop type currently planted in the greenhouse is determined based on the image data, and then the corresponding growth model is retrieved according to the crop type. The acquired image data is compared with the characteristic information in the growth model to determine the current growth stage of the crop, and then the data acquisition frequency of the monitoring unit is adjusted based on the growth stage of the crop.

[0050] The environmental data in the intelligent greenhouse environment monitoring method provided by the embodiments of the present invention includes air temperature and humidity data, soil temperature and humidity data, and light intensity data inside the greenhouse. The greenhouse environment detection method provided by the embodiments of the present invention further includes: based on the air temperature and humidity data, the soil temperature and humidity data, and the light intensity data, if it is determined that at least one of the air temperature, air humidity, soil temperature, soil humidity, and light intensity in the greenhouse exceeds the corresponding threshold range, then control the monitoring device to send out a warning message.

[0051] Specifically, a first air temperature threshold range, a first air humidity threshold range, a first soil temperature threshold range, a first soil humidity threshold range, and a first light intensity threshold range suitable for crop growth are preset in the monitoring device. Compare the air temperature data, air humidity data, soil temperature data, soil humidity data, and light intensity data collected by the monitoring unit with the corresponding threshold ranges. When at least one of them exceeds the corresponding threshold range, it is determined that the environment in the greenhouse is abnormal, and then the corresponding warning message is sent. Users can grasp the appropriate timing of watering, shading, etc. according to the warning message.

[0052] The intelligent greenhouse environment monitoring method provided by the embodiments of the present invention further includes: based on the air temperature and humidity data and the soil temperature and humidity data, if it is determined that the internal environment of the greenhouse reaches the pest growth environment, then control the insecticidal device to start the insecticidal operation.

[0053] Specifically, a second air temperature threshold range, a second air humidity threshold range, a second soil temperature threshold range, and a second soil humidity threshold range suitable for pest growth are preset in the monitoring device. Compare the air temperature data, air humidity data, soil temperature data, and soil humidity data collected by the monitoring unit with the corresponding threshold ranges. When it is determined that these data all reach the corresponding threshold ranges, control the insecticidal device to start the insecticidal operation.

[0054] Further, before controlling the insecticidal device to start the insecticidal operation, it further includes: based on the light intensity data, it is determined that the current environment is night, and according to the production status information, it is determined that the inside of the greenhouse is in a planting state. A second light intensity threshold is preset in the monitoring device. Compare the light intensity data collected by the monitoring unit with the second light intensity threshold. When the light intensity is lower than the second light intensity threshold, it is determined that the current environment is night.

[0055] In this embodiment, only when the inside of the greenhouse is in a planting state, the current environment is night, and the air temperature and humidity and soil temperature and humidity meet the pest growth environment, the insecticidal device is controlled to start the insecticidal operation, which can greatly exert the main function of the insecticidal device and reduce the energy consumption generated by the insecticidal device.

[0056] The greenhouse environment intelligent monitoring method provided by the embodiment of the present invention further includes: collecting power supply status information and / or positioning information of the monitoring device at preset time intervals. Determining that the monitoring device is in a power shortage state according to the power supply status information, and / or determining that the position of the monitoring device has moved according to the positioning information, then controlling the monitoring device to issue an early warning message.

[0057] The voltage monitoring module in the monitoring device can be used to collect input voltage data of the monitoring device, or to collect output voltage data of a power source connected to the monitoring device (such as the solar panel described in the following embodiment). When the collected voltage data is lower than the preset voltage data, it is determined that the monitoring device is in a power shortage state, and the monitoring device is controlled to issue an early warning message.

[0058] The location information of the monitoring device can be collected through the positioning module in the monitoring device. When the collected location information is different from the initialization location, it is determined that the location of the monitoring device has moved, and the monitoring device is controlled to issue an early warning message to prevent the device from being stolen. In order to reduce the power consumption of the monitoring device, the power supply status information and positioning information of the monitoring device can be collected once a day.

[0084] Among them, the buckle 12 includes two rotatably connected claws, and the two claws are detachably connected by a lock; or the two claws are connected by a torsion spring, and under the action of the torsion spring, the two claws are buckled with each other to form a loop buckle.

[0085] Furthermore, the solar panel 4 is installed at one end of the telescopic rod 11 or on the housing 21, and the height of the monitoring device 2 and the solar panel 4 is adjusted simultaneously by the telescopic movement of the telescopic rod 11. The telescopic rod 11 can be controlled to extend or retract according to the height of the greenhouse or the lighting conditions, so as to adjust the height of the monitoring device and the solar panel 4.

[0086] Optionally, the housing 21, the outer shell 241 and the mounting bracket 1 are all made of waterproof and corrosion-resistant hard materials to ensure the reliability of the structure of the entire monitoring system.

[0087] As Figure 2 shown, in some embodiments of the present invention, the monitoring device 2 further includes a voltage monitoring module 26 encapsulated inside the housing 21. The voltage monitoring module 26 is electrically connected to the solar panel 4 and is used to collect the output voltage data of the solar panel 4. The voltage monitoring module 26 is communicatively connected to the control unit 22. The voltage monitoring module 26 can collect the output voltage data of the solar panel 4 or the input voltage data of the monitoring device 2 at a set frequency and send the data to the control unit 22 for the control unit 22 to determine whether the monitoring device 2 is short of power. When it is determined that the monitoring device 2 is short of power, the control unit 22 can send a warning signal to the monitoring terminal 5 through the communication unit 25.

[0088] As Figure 2 shown, in some embodiments of the present invention, the monitoring device 2 further includes a signal monitoring module 27 encapsulated in the housing 21. The signal input end of the communication unit 25 for communicatively connecting with the second monitoring unit 24 is connected to the signal monitoring module 27, and the signal monitoring module 27 is communicatively connected to the control unit 22. The communication status between the second monitoring unit 24 and the communication unit 25 is monitored by the signal monitoring module 27, and the communication status information is sent to the control unit 22. If the communication unit 25 does not receive the signal sent by the second monitoring unit 24 within a preset time period, the control unit 22 determines that the second monitoring unit 24 is short of power and sends a warning signal to the monitoring terminal 5 through the communication unit 25.

[0089] As Figure 2As shown, in some embodiments of the present invention, the monitoring device 2 further includes a positioning module 28 encapsulated inside the housing 21. The signal output end of the positioning module 28 is communicatively connected to the control unit 22. Among them, the positioning module 28 can be a GPS positioning module or a Beidou positioning module. The positioning module 28 can collect the position information of the monitoring device 2 at a set frequency and send the position information to the control unit 22 for the control unit 22 to determine whether the position of the monitoring device 2 has moved. When it is determined that the position of the monitoring device 2 has moved, the control unit 22 sends a warning signal to the monitoring terminal 5 through the communication unit 25.

[0090] As Figure 2 and Figure 4 shown, the intelligent greenhouse environment monitoring system provided by the embodiments of the present invention further includes an insecticidal device 6. The insecticidal device 6 is connected to the mounting bracket 1 and communicatively connected to the control unit 22. The opening and closing of the insecticidal device 6 are controlled by the control unit 22. It should be noted that the insecticidal device 6 can be directly connected to the mounting bracket 1 or connected to the mounting bracket 1 through the housing 21. For example, insecticidal devices 6 are respectively connected to both ends in the length direction of the housing 21.

[0091] As a specific example, as Figure 4 shown, the housing 21 is a cylindrical structure. The mounting bracket 1 is connected to the middle position in the length direction of the housing 21. The image collector 233 is arranged on the side of the housing 21 away from the mounting bracket 1, and the expansion interface 211 is arranged on the periphery of the housing 21. When the housing 21 is suspended in the greenhouse 3 through the mounting bracket 1, the image collector 233 can obtain a larger visual range. Two insecticidal devices 6 are respectively connected to both ends of the cylindrical structure, which can make the installation structure of the monitoring device 2 and the insecticidal device 6 compact while ensuring a larger insecticidal area.

[0092] Among them, the insecticidal device 6 includes an insecticidal electric grid, a protective cover 61 and an insect-attracting light source 62. The protective cover 61 is connected to one end in the length direction of the housing 21, and the insecticidal electric grid is arranged inside the protective cover 61. The insect-attracting light source 62 is arranged outside the protective cover 61 and at the end of the protective cover 61 away from the housing 21. The insecticidal electric grid and the insect-attracting light source 62 are respectively communicatively connected to the control unit 22.

[0093] Among them, the insect-attracting light source 62 can adopt an LED lamp tube, and the light wave wavelength of the lamp tube is 320 - 680 nm. The insecticidal electric grid adopts a stainless steel high-voltage electric grid. The opening and closing of the insect-attracting light source 62 and the insecticidal electric grid are controlled by the control unit 22. The insect-attracting light source 62 is controlled by the control unit 22 to emit light at night, attracting pests by using the phototaxis of pests, and then killing the pests by using the insecticidal electric grid. Among them, the insecticidal device 6 is provided with an electric grid overcurrent short-circuit protection module to prevent the electric grid from short-circuiting due to residual insect bodies.

[0094] Specifically, the housing 21 is a cylindrical structure, and protective covers 61 are connected to both ends of the cylindrical structure. The protective covers 61 are cylindrical structures coaxially arranged with the housing 21 and having the same diameter, and the housing 21 and the insecticidal device 6 are combined to form an integral cylindrical structure. The insecticidal electric grid is also a cylindrical structure and is coaxially arranged inside the corresponding protective cover 61, and the insect attracting light source 62 is arranged inside the insecticidal electric grid, so that insect killing can be achieved on the entire circumference of the insecticidal device 6.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
