Description

Technical Field

[0001] This application relates to the technical field of greenhouse temperature and humidity detection, and specifically discloses a greenhouse temperature and humidity detection device. Background Art

[0002] During the cultivation of Chinese medicinal materials, they will be invaded by pests and diseases or affected by adverse environmental factors, resulting in pest and disease hazards. Chongqing is located in the southwest of China and belongs to the subtropical humid climate zone with a large annual precipitation. The climate in Chongqing is humid, and local Chinese medicinal materials are vulnerable to pest and disease attacks, such as black spot disease, rust disease, etc. Such pest and disease problems will directly affect the yield of local Chinese medicinal materials, reduce the supply of medicinal materials, and then affect the supply and price fluctuations in the Chongqing Chinese medicinal materials market. For Chinese medicinal materials affected by pests and diseases, the content of their active ingredients may also be affected, thus reducing the quality and efficacy of the medicine and affecting human health and safety. The frequent occurrence of pest and disease problems in Chinese medicinal materials will lead to a decrease in the yield of Chinese medicinal materials, a decline in the quality of medicinal materials, and a reduction in active ingredients, which will seriously affect public health. Traditional monitoring methods have alleviated the problem of pest and diseases in Chinese medicinal materials to a certain extent. However, traditional monitoring methods have problems such as poor real-time performance, high labor intensity, and still relying mainly on expert experience, with low efficiency. To effectively monitor the degree of pest and diseases of Chinese medicinal materials, aiming at the problem of monitoring environmental factor information such as temperature, humidity, light, and air flow required at different growth stages during the growth process of Chinese medicinal materials, a large number of technical improvements have been made in this regard;

[0003] Measuring the water content of leaves is of great significance for agricultural, ecological, and plant physiological research. It not only helps to understand the health status of individual plants but also can be used for agricultural management and ecological protection strategy formulation at the macroscopic level. However, the current leaf capacitance detection method is likely to cause damage to plants, thus reducing the accuracy of detection.

[0004] Chongqing is located in the subtropical humid climate zone with distinct seasons, abundant rainfall, hot and humid summers, and mild and less rainy winters. Such climate conditions are conducive to the growth of various crops but also pose challenges to agricultural management, especially in terms of water resource management. Due to the uneven distribution of rainfall in the Chongqing area, droughts and floods occur frequently, which have an adverse impact on crop growth;

[0005] Returning to greenhouse cultivation, common temperature sensors, whether they are insert type or high-precision type temperature sensors, and humidity sensors, whether they are absolute humidity sensors or relative humidity sensors, are all local for greenhouse cultivation. This local area is too large for the plants being grown, and essentially, it is not precise enough. In view of this, the inventor proposes a greenhouse temperature and humidity detection device. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that the traditional greenhouse temperature and humidity detection device is not accurate enough.

[0007] In order to achieve the above object, the present invention provides the following basic scheme:

[0008] A greenhouse temperature and humidity detection device includes a partitioned detection area, the partitioned detection area is arranged in the greenhouse, and also includes a detection component arranged in the partitioned detection area, the detection component includes:

[0009] A receiving box for receiving inoculated plants, a water outlet component arranged based on the receiving box, and a temperature and humidity detection component for accurately detecting temperature and humidity;

[0010] The temperature and humidity detection component comprises a temperature sensor, a humidity sensor and a moving component. The temperature sensor and the humidity sensor move based on the moving component, and the temperature sensor and the humidity sensor act on the leaves of the plant.

[0011] The principles and effects of this basic solution are:

[0012] 1. Compared with the prior art, this device has a simple structure and ingenious design. The first point is the greenhouse division. After the division, the area of ​​the greenhouse becomes smaller and becomes each independent small area. The improved temperature and humidity detection devices of this scheme are all set in each independent small area, and the temperature and humidity of each independent small area are monitored. The operation is simpler, and for the temperature and humidity detection device, the detection result is more accurate.

[0013] 2. Compared with the prior art, this device has a simple structure and adopts a more accurate temperature and humidity detection device. The temperature and humidity detection device is all targeted at the leaves, and is no longer targeted at the entire plant. Compared with targeting the entire plant, targeting the leaves is more accurate for temperature and humidity detection, thereby solving the problem of insufficient accuracy of traditional greenhouse temperature and humidity detection devices.

[0014] 3. Compared with the prior art, the temperature and humidity detection devices of this device are all movable. Therefore, the temperature and humidity detection devices can not only act on the leaves, but also no longer act on a specific leaf. More leaves are acted on, so the detection is more accurate, thereby solving the problem that the traditional greenhouse temperature and humidity detection devices are not accurate enough.

[0015] 4. Compared with the prior art, the present device is provided with a camera and a supporting camera image processing module. By using the photographing mode, water droplets and pests on the leaves are obtained to determine the current pest and disease parameters of the Chinese medicinal material. According to the preset pest and disease level determination criteria corresponding to the current growth cycle of the Chinese medicinal material and the current pest and disease status, the current pest and disease level of the target plant can be determined, effectively monitoring the pests and diseases of the Chinese medicinal material in the planting equipment and giving an alarm in time, enabling the monitoring personnel to take measures in time to reduce the losses caused by pests and diseases. For the water droplet situation, it can assist the temperature and humidity detection device to further accurately detect the leaves.

[0016] Further, the partitioned detection area is composed of several cross bars and vertical bars. The cross bars and vertical bars form the partitioned detection area, and the bottoms of the cross bars and vertical bars are buried in the soil. After partitioning, the area of the greenhouse becomes smaller, becoming individual small areas. The improved temperature and humidity detection devices in this solution are all arranged in each independent small area to monitor the temperature and humidity of each independent small area, making the operation simpler.

[0017] Further, the receiving box sequentially includes a water pipe, a cavity body arranged on the water pipe, a connection box communicated with the cavity body, a controller arranged on one side of the connection box, and a plant installation area arranged on the top of the connection box from bottom to top. The water pipe is buried in the soil, and the soil fills the cavity body to the plant installation area. The plant installation area is used to achieve precise positioning and planting of plants. Although a certain amount of planting space is lost, it is beneficial to the subsequent work of the temperature and humidity detection components.

[0018] Further, the water pipes located at the lower part of the receiving box all form a water pipe network. One end of the water pipe network is connected to a water pump, and the other end of the water pipe network is connected to a water tank. The water tank is installed in the greenhouse. The water pipes all form a water pipe network, which can then act reasonably in the greenhouse and is also convenient for manual control.

[0019] Further, the plant installation area includes several installation grooves opened on the top of the connection box, a water spraying plate arranged in the grooves of the installation grooves, and several water spraying holes opened on the water spraying plate. The water spraying plate is a hollow plate, and the bottom of the hollow plate is communicated with a storage box. Guide pipes are arranged around the storage box, and the guide pipes are connected to the water pipe network. A connection hole is also arranged on the water spraying plate, and the plants are cultivated through the connection hole with the soil located in the plant installation area. Water comes out from the water pipe network to the guide pipes, the guide pipes discharge water to the storage box, the storage box discharges water to the water spraying plate, and then the water is discharged through the water spraying holes to complete the upward water spraying operation for the plants.

[0020] Furthermore, mounting plates are provided on both sides of the connection box, and the temperature and humidity detection components are all mounted on the mounting plates. The moving component includes a connection frame perpendicularly and fixedly connected to the mounting plate, a mounting bracket detachably connected to the connection frame, a lead screw pair arranged on the mounting bracket, and a motor for slidably connecting the lead screw pair. A moving block for movement is connected to the lead screw pair, and the temperature sensor and the humidity sensor are both mounted on the moving block. The movement of the temperature sensor and the humidity sensor is realized. The temperature and humidity detection device can not only act on the leaves, but also no longer act specifically on a certain leaf. More leaves are affected, so the detection is more accurate.

[0021] Furthermore, a bracket is obliquely mounted and connected to the moving block. The temperature sensor and the humidity sensor are integrated, and the integrated temperature sensor and humidity sensor are mounted at the free end of the bracket. The bracket is bendable. The bendability of the bracket enables the temperature sensor and the humidity sensor to act on different areas of the leaves, which is manually adjustable and has higher flexibility.

[0022] Furthermore, a camera component used in conjunction with the integrated temperature sensor and humidity sensor is further included. The camera component includes a high-definition camera, a medicinal material image acquisition module, and an image data analysis module. Both the medicinal material image acquisition module and the image data analysis module are electrically connected to the processor. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features, and effects in accordance with the present invention as follows.

[0029] The reference numerals in the accompanying drawings of the specification include: partition detection area 1, planted plants 2, installation groove 3, water spraying plate 4, connection box 5, cavity body 6, water pipe 7, storage box 8, conduit 9, water spraying holes 10, connection holes 11, installation plate 12, controller 13, connection frame 14, installation bracket 15, fixing screws 16, motor 17, high-definition camera 18, bracket 19, temperature sensor and humidity sensor 20, medicinal material image acquisition module 21, image data analysis module 22, processor 23.

[0030] The embodiments are as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown as follows:

[0031] A greenhouse temperature and humidity detection device includes a partition detection area 1, the partition detection area 1 is arranged in the greenhouse, and further includes a detection component arranged in the partition detection area 1.

[0032] Regarding the partition detection area 1, as Figure 1 shown, the partition detection area 1 is composed of several cross bars and vertical bars. The cross bars and vertical bars form the partition detection area 1. The bottoms of the cross bars and vertical bars are buried in the soil. After partitioning, the area of the greenhouse becomes smaller and becomes each independent small area. The improved temperature and humidity detection devices in this solution are all arranged in each independent small area to monitor the temperature and humidity of each independent small area, making the operation simpler.

[0033] Specifically: Since the greenhouse is very large and occupies a large area, in order to ensure that the subsequent detection components can achieve accurate detection, the greenhouse is first partitioned and then the detection components are installed. Although the number of detection components increases and the cost rises, the detection accuracy is improved, which has a good effect and more beneficial effects for some planted plants 2 with requirements for temperature and humidity.

[0034] The detection component includes:

[0035] A receiving box for receiving the planted plants 2, a water outlet component arranged based on the receiving box, and a temperature and humidity detection component for accurately detecting temperature and humidity;

[0036] Specifically:

[0037] The receiving box successively includes a water pipe 7 from bottom to top, a cavity body 6 provided on the water pipe 7, a connection box 5 communicated with the cavity body 6, a controller 13 provided on one side of the connection box 5, and a planting area 2 for plants provided on the top of the connection box 5. The water pipe 7 is buried in the soil, and the soil fills the cavity body 6 to the planting area 2 for plants. The planting area 2 for plants is used to achieve precise positioning and planting of the plants. Although a certain amount of planting space is lost, it is beneficial to the subsequent work of the temperature and humidity detection components. The water pipes 7 located at the lower part of the receiving box form a water pipe network. One end of the water pipe network is connected to a water pump, and the other end of the water pipe network is connected to a water tank. The water tank is installed in the greenhouse. The water pipes 7 form a water pipe network, which can act reasonably in the greenhouse and is also convenient for manual control.

[0038] The planting area 2 for plants includes a plurality of installation grooves 3 opened on the top of the connection box 5, a water spraying plate 4 provided in the grooves of the installation grooves 3, and a plurality of water spraying holes 10 opened on the water spraying plate 4. The water spraying plate 4 is a hollow plate, and a storage box 8 is communicated with the bottom of the hollow plate. A conduit 9 is provided around the storage box 8, and the conduit 9 is connected to the water pipe network. A connection hole 11 is also provided on the water spraying plate 4, and the plants 2 are cultivated through the connection hole 11 with the soil in the planting area 2 for plants.

[0039] Specifically: Under the action of the water pump, water flows out from the water pipe network to the conduit 9, the conduit 9 discharges water to the storage box 8, the storage box 8 discharges water to the water spraying plate 4, and then water is discharged through the water spraying holes 10 to complete the upward water spraying operation for the plants 2 from bottom to top.

[0040] The upward water spraying operation for the plants 2 from bottom to top: Compared with the downward water spraying, the probability and utilization rate of suddenly reusing water are improved. And although the downward water spraying is more comprehensive for the plants 2, under the action of the water pump, this defect can be avoided, and the plants 2 can still obtain water comprehensively.

[0041] Regarding the start of the water pump, it depends on the subsequent temperature and humidity detection components. mainly, it is judged whether the water pump starts based on the data obtained by the temperature and humidity detection components. For example, when the temperature is too high or the humidity is too low and water needs to be supplemented, the water pump will start to supply water to the plants 2.

[0042] Another core of this case lies in the temperature and humidity detection components:

[0043] The temperature and humidity detection components: include a temperature sensor, a humidity sensor 20, and a moving component. The temperature sensor and the humidity sensor 20 move based on the moving component, and both the temperature sensor and the humidity sensor 20 act on the leaves of the plants 2.

[0044] Specifically, mounting plates 12 are provided on both sides of the connection box 5. The temperature and humidity detection components are all mounted on the mounting plates 12. The moving component includes a connection frame 14 vertically and fixedly connected to the mounting plate 12, a mounting bracket 15 detachably connected to the connection frame 14, a fixing screw 16 provided between the mounting bracket 15 and the connection frame 14, a lead screw pair provided on the mounting bracket 15, and a motor 17 for slidably connecting to the lead screw pair. A moving block for moving is connected to the lead screw pair. The temperature sensor and the humidity sensor 20 are both mounted on the moving block. The movement of the temperature sensor and the humidity sensor 20 is realized. The temperature and humidity detection device can not only act on the leaves, but also no longer act specifically on a certain leaf. More leaves are affected, so the detection is more accurate.

[0045] Specifically, a bracket 19 is obliquely mounted and connected to the moving block. The temperature sensor and the humidity sensor 20 are integrated, and the integrated temperature sensor and humidity sensor 20 are mounted at the free end of the bracket 19. The bracket 19 is bendable. The bendability of the bracket 19 enables the temperature sensor and the humidity sensor 20 to act on different areas of the leaves, which is manually adjustable and has higher flexibility.

[0046] In summary: The temperature sensor and the humidity sensor 20 no longer perform overall detection, but leaf detection. The lead screw pair is used to increase the range of leaf detection, improve the detection sample data, and thus improve the accuracy. Moreover, by using the bendable bracket 19, flexible adjustment within a small area of the leaf is realized, further improving the accuracy;

[0047] Similarly, if only relying on the temperature sensor and the humidity sensor 20, there is a mechanical error, and this mechanical error is inevitable. To further reduce this error rate, a camera component is provided. Regarding the camera component:

[0048] It also includes a camera component used in cooperation with the integrated temperature sensor and humidity sensor 20. The camera component includes a high-definition camera 18, a medicinal material image acquisition module 21, and an image data analysis module 22. The medicinal material image acquisition module 21 and the image data analysis module 22 are both electrically connected to a processor 23. The processor 23 is essentially a chip and is installed in the controller 13.

[0049] The high-definition camera 18 is provided on the moving block, realizing the flexible movement of the high-definition camera 18. The high-definition pictures taken by the high-definition camera 18 are sent to the medicinal material image acquisition module 21. The pictures are collected by the medicinal material image acquisition module 21 and then sent to the image data analysis module 22. The image data analysis module 22 mainly obtains the water droplets on the leaves. By using the amount of water droplets, it assists the data of the temperature sensor and the humidity sensor 20, thereby helping the relevant staff to make the most accurate and flexible judgment.

[0050] Moreover, it is also possible to obtain pictures, detect pests on the leaves, determine the current pest and disease parameters of the Chinese medicinal material, and determine the current pest and disease level of the target plant according to the preset pest and disease level determination criteria corresponding to the current growth cycle of the Chinese medicinal material and the current pest and disease status, so as to effectively monitor the pests and diseases of the Chinese medicinal material in the planting equipment and give timely warnings, enabling the monitoring personnel to take measures in time and reducing the losses caused by pests and diseases.

[0051] This device solves the problem that the traditional greenhouse temperature and humidity detection device is not accurate enough.

[0052] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
