Description

Technical Field

[0001] This invention relates to the field of greenhouse control technology, and in particular to a control device and method for a solar greenhouse insulation blanket. Background Technology

[0002] Solar greenhouse cultivation is a unique greenhouse crop cultivation method in China, widely used due to its simple construction and low cost. However, previous inventions were mostly aimed at multi-span greenhouses with advanced control equipment or general technologies, lacking control methods specifically for solar greenhouses. Environmental control equipment in solar greenhouses mainly includes insulation blankets, roll-up films, and roof windows. Among these, insulation blankets play a crucial role in greenhouse production in low-temperature regions of northern China; misoperation can cause major production accidents, leading to reduced yields or even crop failure. Errors in the operation of insulation blankets also pose a significant safety threat to production personnel; accidents caused by malfunctioning limit switches or over-rolling of insulation blankets are frequent.

[0003] Patent CN101887279A discloses a control device for a greenhouse insulation blanket. This device includes a motor, temperature sensor, humidity sensor, light sensor, and controller, enabling automatic control of the insulation blanket. However, this device only controls the blanket's folding, unfolding, and stopping based on monitored environmental factors, making it highly susceptible to environmental influences, unable to identify whether workers are in danger, and prone to mechanical failure. Patent CN206411534U discloses a novel automatic control system for greenhouse insulation blankets, including a greenhouse body, insulation blanket, uprights, support rods, a blanket rolling machine, and sensors monitoring the rolling machine's operating status. This system can monitor the environmental conditions inside and outside the greenhouse, as well as the operating status of the blanket rolling machine; however, it cannot identify the positional relationship between workers and the insulation blanket.

[0004] Existing technologies have largely achieved automatic remote control of greenhouse insulation blankets, but they do not monitor the operators' movements, thus failing to guarantee safety. Especially in automatic control mode, the lack of monitoring of operators' movements increases safety risks. Therefore, these problems urgently need to be addressed. Summary of the Invention

[0005] The purpose of this invention is to provide a control device and method for a greenhouse insulation blanket, which enables remote automatic control of the insulation blanket; controls the opening degree of the insulation blanket by monitoring the environment inside and outside the greenhouse and receiving feedback from sensors; and ensures the safe operation of the insulation blanket by identifying the operator.

[0006] To achieve the above objectives, the present invention provides a control device for a greenhouse insulation blanket, comprising a greenhouse, an insulation blanket being provided at the upper end of the greenhouse, one end of the insulation blanket being fixedly connected to the top of the greenhouse, and a crossbar being provided at the other end of the insulation blanket, the crossbar being connected to a control rod, the control rod being connected to the bottom of the greenhouse, a reduction motor being provided on the crossbar, an internal greenhouse environment sensor node being provided inside the greenhouse, an external greenhouse environment sensor node being provided outside the greenhouse, an image monitoring sensor node being installed at the front of the greenhouse, and a main controller node being provided inside the greenhouse; the main controller node is located in the rear wall or side room of the greenhouse.

[0007] Preferably, the greenhouse environment sensor nodes, greenhouse exterior environment sensor nodes, image monitoring sensor nodes, and main controller nodes are all connected via wireless communication.

[0008] Preferably, the greenhouse environment sensor node is used to acquire real-time data on air temperature, air humidity and light intensity in the greenhouse;

[0009] The greenhouse external environment sensor node is used to acquire real-time data on external air temperature, air humidity, light intensity, wind speed and direction, and rainfall status.

[0010] Multiple image monitoring sensor nodes are set up to take frontal photos of the greenhouse;

[0011] The main controller node is used to acquire data from the greenhouse internal environment sensor node, the greenhouse external environment sensor node, and the image monitoring sensor node, and to perform image recognition and judgment to control the retraction, unfolding, and stopping of the insulation blanket geared motor.

[0012] The present invention also provides a method for controlling the heat preservation of a solar greenhouse, comprising the following steps:

[0013] S1. Monitor the environment inside the greenhouse through the greenhouse environment sensor node, monitor the environment outside the greenhouse through the greenhouse environment sensor node, and obtain images of the outline of the greenhouse roof and the area where the insulation blanket is spread through the image monitoring sensor node.

[0014] S2. The main controller node acquires data from the greenhouse internal environment sensor node, the greenhouse external environment sensor node, and the image monitoring sensor node, calculates the current opening degree, controls the forward and reverse rotation of the insulation blanket reduction motor according to the target opening degree, and determines whether the target opening degree has been reached or whether there is an alarm message. If the target opening degree has been reached or there is an alarm message, the insulation blanket reduction motor stops rotating.

[0015] Preferably, the main controller node functions include controlling the forward and reverse rotation of the insulation blanket geared motor, acquiring data from each sensor node, processing and analyzing data, and communicating with a remote server.

[0016] Among them, the forward and reverse rotation control of the thermal insulation quilt geared motor is controlled by the main node signal output to control the forward and reverse rotation contactor of the thermal insulation quilt geared motor to achieve the unfolding, folding and stopping operation of the thermal insulation quilt.

[0017] The sensor node data acquisition function refers to accessing sensor nodes and acquiring environmental data and image monitoring sensor node data inside and outside the greenhouse through low-power wireless data transmission communication of self-organizing network;

[0018] The data processing and analysis function mainly includes two parts. The first part is the setting of the target opening degree of the insulation blanket. This function calculates the target opening degree of the insulation blanket according to the pre-set opening degree calculation model after acquiring the temperature inside and outside the greenhouse. The second part is the feedback control of the insulation blanket unfolding, retracting, and stopping. After the main controller node obtains the target opening degree, it controls the unfolding or retracting operation of the insulation blanket. It judges the current opening degree of the insulation blanket by receiving data from the image monitoring sensor node in real time, compares it with the target opening degree, and stops the operation when the current opening degree of the insulation blanket reaches the target opening degree and issues an alarm. When the alarm is cleared, it continues to operate.

[0019] Remote server communication function refers to the main controller node supporting network communication, being able to establish a connection with the server through network communication protocols, receive control commands from the server, and upload the current working status.

[0020] Preferably, the main controller node is a multi-tasking embedded system consisting of an ARM processor and a real-time operating system.

[0021] Preferably, the image monitoring sensor node acquires continuous images of the outline of the greenhouse roof and the area where the insulation blanket is spread out, and the main controller node determines the current opening degree of the insulation blanket by projecting distance, thereby realizing feedback control of the opening degree of the insulation blanket.

[0022] Image monitoring sensor nodes capture images of the positions of personnel and the greenhouse. The main controller node determines the positional relationship between the personnel and the greenhouse, thereby determining whether the insulation operation is safe. When personnel are detected approaching and there is a safety hazard, the main controller issues an alarm and stops the current operation.

[0023] Preferably, the process of obtaining the opening degree of the insulation blanket is to first use a shape-based recognition method to identify the greenhouse and the horizontal bar of the insulation blanket in the image, and then calculate the relative position of the horizontal bar of the insulation blanket in the projection of the greenhouse to calculate the opening degree of the insulation blanket.

[0024] The outer surface of the greenhouse is an arc-shaped structure. When calculating the opening of the insulation blanket, a quadratic function model is used to fit the outer surface of the greenhouse. The ground is taken as the coordinate point 0 during the calculation process. The fitting formula is as shown in equation (1):

[0025] y = ax2 +bx (1)

[0026] Where a and b are coefficients obtained by measuring the actual conditions of the greenhouse. The distance between the horizontal bar of the insulation blanket and the ground as recognized by the image is taken as the current y value. The distance between the horizontal bar and the ground when the insulation blanket is fully open is taken as y. f Thermal quilt opening degree O r The calculation formula is as shown in equation (2):

[0027]

[0028] When the number of image monitoring sensor nodes is greater than 1, the opening degree of the insulation blanket is taken as the average value of the opening degree of the insulation blanket calculated from the images obtained by all image monitoring sensor nodes.

[0029] Preferably, the determination of whether personnel are in a safe area is based on the identification of the greenhouse, delineating the area from the insulation blanket horizontal bar to the top of the greenhouse as a danger zone, and then identifying personnel within the area. When an identified person enters the danger zone, an alarm is triggered and the current insulation blanket control operation is stopped.

[0030] Therefore, the technical effects of the above-mentioned greenhouse insulation blanket control device and method are as follows:

[0031] (1) Image monitoring solves the problem of poor safety of greenhouse insulation blankets. By using image recognition, the relative position between personnel and the insulation blanket crossbar and the insulation blanket deceleration motor is determined, and the opening and closing operation of the insulation blanket is stopped in time, ensuring the safety of personnel when the insulation blanket is in operation.

[0032] (2) Adopt a fully wireless communication method to avoid excessive wiring in the greenhouse, so that the controller can be installed on the insulation blanket of the completed solar greenhouse.

[0033] (3) By simultaneously acquiring environmental data inside and outside the greenhouse through the greenhouse environmental sensor nodes and the greenhouse external environmental sensor nodes, it is possible to execute the insulation blanket opening control model constructed according to different crops and different cultivation methods. At the same time, by using the greenhouse internal and external environmental parameters as model variables, the opening control of the insulation blanket can be made more precise.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0042] Example 1

[0043] like Figure 1 As shown, a control device for a solar greenhouse insulation blanket includes a greenhouse 1. An insulation blanket 2 is installed at the upper end of the greenhouse 1. One end of the insulation blanket 2 is fixedly connected to the top of the greenhouse 1, and the other end of the insulation blanket 2 is provided with an insulation blanket crossbar 9. The insulation blanket crossbar 9 is connected to an insulation blanket control rod 3, and the insulation blanket control rod 3 is connected to the bottom of the greenhouse 1. An insulation blanket reduction motor 4 is installed on the insulation blanket crossbar 9. An internal greenhouse environment sensor node 5 is installed inside the greenhouse 1, an external greenhouse environment sensor node 6 is installed outside the greenhouse 1, an image monitoring sensor node 7 is installed at the front of the greenhouse 1, and a main controller node 8 is also installed inside the greenhouse 1. The main controller node 8 is located in the rear wall or side room of the greenhouse.

[0044] Depending on the actual situation, the heat insulation blanket reduction motor 4 can be set on the side or in the middle of the greenhouse 1.

[0045] The greenhouse internal environment sensor node 5, the greenhouse external environment sensor node 6, the image monitoring sensor node 7, and the main controller node 8 are all connected wirelessly, which can reduce the wiring in greenhouse 1.

[0046] The greenhouse environment sensor node 5 is used to acquire real-time data on air temperature, air humidity and light intensity in greenhouse 1;

[0047] The greenhouse external environment sensor node 6 is used to acquire real-time data on the external air temperature, air humidity, light intensity, wind speed and direction, and rainfall status of greenhouse 1.

[0048] Multiple image monitoring sensor nodes 7 are set and installed directly in front of greenhouse 1 to take frontal photos of greenhouse 1; when the greenhouse is long, multiple image monitoring sensor nodes can be set.

[0049] The main controller node 8 is the core processing unit, which is used to acquire data from the greenhouse environment sensor node 5, the greenhouse external environment sensor node 6, and the image monitoring sensor node 7, and to perform image recognition and judgment to control the retraction, unfolding, and stopping of the insulation blanket reduction motor 4.

[0050] Example 2

[0051] like Figure 2 As shown, a method for controlling the heat insulation of a solar greenhouse includes the following steps:

[0052] S1. Monitor the environment inside the greenhouse through environmental sensor nodes inside the greenhouse, and monitor the environment outside the greenhouse through environmental sensor nodes outside the greenhouse.

[0053] S2. The main controller node acquires data from the greenhouse internal environment sensor node, the greenhouse external environment sensor node, and the image monitoring sensor node, calculates the current opening degree, controls the forward and reverse rotation of the insulation blanket reduction motor according to the target opening degree, and determines whether the target opening degree has been reached or whether there is an alarm message. If the target opening degree has been reached or there is an alarm message, the insulation blanket reduction motor stops rotating.

[0054] The main controller node functions include controlling the forward and reverse operation of the insulation blanket geared motor, acquiring data from each sensor node, processing and analyzing data, and communicating with a remote server.

[0055] Among them, the forward and reverse rotation control of the thermal insulation quilt geared motor is controlled by the main node signal output to control the forward and reverse rotation contactor of the thermal insulation quilt geared motor to achieve the unfolding, folding and stopping operation of the thermal insulation quilt.

[0056] The sensor node data acquisition function refers to accessing sensor nodes and acquiring environmental data and image monitoring sensor node data inside and outside the greenhouse through low-power wireless data transmission communication of self-organizing network;

[0057] The data processing and analysis function mainly includes two parts. The first part is the setting of the target opening degree of the insulation blanket. This function calculates the target opening degree of the insulation blanket according to the pre-set opening degree calculation model after acquiring the temperature inside and outside the greenhouse. The second part is the feedback control of the insulation blanket unfolding, retracting, and stopping. After the main controller node obtains the target opening degree, it controls the unfolding or retracting operation of the insulation blanket. It judges the current opening degree of the insulation blanket by receiving data from the image monitoring sensor node in real time, compares it with the target opening degree, and stops the operation when the current opening degree of the insulation blanket reaches the target opening degree and issues an alarm. When the alarm is cleared, it continues to operate.

[0058] The remote server communication function refers to the main controller node supporting mobile network communication, being able to establish a connection with the server through network communication protocols, receiving control commands from the server, and uploading the current working status.

[0059] The main controller node is a multi-tasking embedded system composed of ARM and a real-time operating system. Its main functions run independently as tasks to avoid monopolizing processor resources and causing functional failure.

[0060] The image monitoring sensor node acquires continuous images of the outline of the greenhouse roof and the area where the insulation blanket is spread out. The main controller node determines the current opening degree of the insulation blanket by projecting distance, thereby realizing feedback control of the opening degree of the insulation blanket.

[0061] Image monitoring sensor nodes capture images of the positions of personnel and the greenhouse. The main controller node determines the positional relationship between the personnel and the greenhouse, thereby determining whether the insulation operation is safe. When personnel are detected approaching and there is a safety hazard, the main controller issues an alarm and stops the current operation.

[0062] Image recognition methods, since the images are fixed, use color thresholding for recognition.

[0063] (1) The image is segmented by using the color differences of the greenhouse, the insulation blanket and other scenes, and then the image is converted into a binary image to achieve image preprocessing.

[0064] (2) A continuous outline of the greenhouse roof and the unfolded area of ​​the insulation blanket were obtained using the region growing method. Specifically, Euclidean distance was used to determine pixel differences; if a pixel has four surrounding pixels that belong to the region, then that pixel also belongs to the region. This method was used to remove noise from the image.

[0065] (3) Finally, the greenhouse and insulation blanket are identified in the image. The identification process uses a topology-based feature recognition method. The topology descriptor is a rectangle. After limiting the size range and rotation angle of the rectangle, it is matched with the elements in the image to extract the greenhouse and insulation blanket.

[0066] like Figure 3 As shown, Figure 3 Area A in the image is a danger zone. The process of obtaining the opening degree of the insulation blanket first uses a shape-based recognition method to identify the greenhouse and the horizontal bar of the insulation blanket in the image, and then calculates the relative position of the horizontal bar of the insulation blanket in the projection of the greenhouse, and calculates the opening degree of the insulation blanket.

[0067] The outer surface of the greenhouse has an arc-shaped structure. When calculating the opening of the insulation blanket, a quadratic function model is used to fit the outer surface of the greenhouse. a and b are obtained by measuring the actual situation of the greenhouse. In the calculation process, the ground is taken as the coordinate point 0, and the fitting formula is as shown in equation (1):

[0068] y = ax 2 +bx (1)

[0069] Where a and b are coefficients, the distance between the horizontal bar of the insulation blanket and the ground as recognized by image recognition is taken as the current y value, and the distance between the horizontal bar and the ground when the insulation blanket is fully open is taken as y. f Thermal quilt opening degree O r The calculation formula is as shown in equation (2):

[0070]

[0071] In practical use, the number of image monitoring sensor nodes should be set reasonably according to the length of the greenhouse. If the number of image monitoring sensor nodes is greater than 1, the main controller node will average the opening data of all image monitoring sensor nodes, and use the average opening as the judgment standard.

[0072] The determination of whether personnel are in a safe area is based on the identification of the greenhouse, the greenhouse and a certain area around the greenhouse are designated as dangerous areas, and personnel in the area are identified. When the identified personnel enter the dangerous area, an alarm is triggered and the current heat preservation control operation is stopped.

[0073] When the angle between the thermos cup's horizontal bar and the ground is detected to be greater than 30°, an alarm message is sent to the user and the blanket-rolling action is stopped.

[0074] In addition to judging the approach of personnel, the safety control measures also include judging the wind speed. Users can set the operable limit wind speed based on factors such as the structural strength and weight of the insulation blanket. When the wind speed value obtained by the main controller node is greater than the limit wind speed, the control stops the unfolding and closing operation of the insulation blanket to ensure the safe operation of the insulation blanket.

[0075] Therefore, the present invention adopts the above-mentioned control device and method for a solar greenhouse insulation blanket to realize remote automatic control of the insulation blanket; the opening degree of the insulation blanket is controlled by monitoring the environment inside and outside the greenhouse and the feedback of sensors; and the operation safety of the insulation blanket is ensured by identifying the operator.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
