Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and more specifically to a method and system for controlling crop irrigation based on the Internet of Things. Background Technology

[0002] With rapid economic development, the problem of freshwater scarcity has become increasingly severe, especially in the agricultural sector. Irrigation water accounts for a large proportion of the country's total water consumption. However, many regions still rely on traditional methods for agricultural irrigation, such as flood irrigation and manual watering. These extensive irrigation methods not only result in a significant waste of water resources but also often lead to situations where irrigation is not timely, excessive, or insufficient due to the inability to accurately control the timing and amount of water, seriously affecting the normal growth of crops. Summary of the Invention

[0003] The purpose of this invention is to provide a method and system for controlling crop irrigation based on the Internet of Things (IoT) to address the shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an Internet of Things-based crop irrigation control method, which determines the crop management range information, sets up multiple sensors within the crop management range, and collects crop environmental information through the multiple sensors, wherein the crop environmental information includes soil moisture, soil temperature, light intensity, and rainfall.

[0005] The crop environmental information collected by multiple sensors is transmitted to the irrigation platform. The crop environmental information is processed and analyzed to obtain an irrigation plan, which includes irrigation equipment, irrigation time of irrigation equipment and irrigation volume.

[0006] The irrigation plan controls the corresponding irrigation equipment to irrigate crops and provides real-time irrigation solutions.

[0007] In a preferred embodiment, the step of determining the crop management area information, setting up multiple sensors within the crop management area, and collecting crop environmental information through the multiple sensors includes:

[0008] Delineate the crop management area, obtain images of the crop management area and the location information of the irrigation equipment within the crop management area as the crop management area information, and mark the irrigation equipment in the image;

[0009] Transmit crop management area information and images to the irrigation platform;

[0010] Multiple sensors are installed within the crop management area, including temperature sensors, humidity sensors, light sensors, and weather sensors. The locations of the sensors are marked on the image of the irrigation platform.

[0011] Crop environmental information is collected through multiple sensors.

[0012] In a preferred embodiment, the step of transmitting crop environmental information collected by multiple sensors to an irrigation platform, processing and analyzing the crop environmental information to obtain an irrigation plan includes:

[0013] Establish transmission channels between multiple sensors and the irrigation platform, and set up a subsystem and multiple retention nodes in the transmission channels;

[0014] The crop environmental information collected by multiple sensors is transmitted through the transmission channel. During the transmission process, the crop environmental information is protected by the system and multiple storage nodes until it is transmitted to the irrigation platform.

[0015] The crop environmental information is cleaned, and the cleaned crop environmental information is marked in the image of the corresponding sensor collection range. The current actual water volume and average water consumption of the crop environmental information are obtained as the current water volume information.

[0016] The types of crops in the image are obtained, and the corresponding irrigation equipment, irrigation time, and irrigation amount are formulated based on the current water volume information, the sensor acquisition range, the current water volume information, and the water requirements of the crop type. The irrigation amount is the average irrigation amount per unit irrigation time.

[0017] In a preferred embodiment, the step of establishing a transmission channel between multiple sensors and the irrigation platform, and setting up a subsystem and multiple retention nodes in the transmission channel, includes:

[0018] A transmission channel is established between each sensor and the irrigation platform. Multiple subordination points are set in the transmission channel, and the subordination points are correlated to obtain a subordination group. The subordination group is located in the network position of the transmission channel close to the sensor. There are two subordination groups in a single transmission channel.

[0019] Multiple retention spaces are set in the transmission channel, and multiple retention points are set in the retention spaces to obtain retention nodes. The number of retention points is the same as the number of subordinate points, and multiple retention points are associated with each other.

[0020] Multiple storage spaces within a single transmission channel communicate with each other.

[0021] In a preferred embodiment, the step of transmitting crop environmental information collected by multiple sensors through a transmission channel, and safeguarding the transmission of crop environmental information through a control group and multiple retention nodes during the transmission process, includes:

[0022] Two unit carriers are set up between multiple sensors and transmission channels. Each unit carrier includes multiple connected sub-carriers, and the two unit carriers are interconnected.

[0023] The crop environment information collected by the sensor is randomly stored in one unit carrier and randomly distributed in multiple sub-carriers within the unit carrier;

[0024] Both unit carriers are transmitted through the transmission channel. The unit carrier containing crop environmental information is given priority in the transmission channel. The two sub-carriers are connected to the unit carrier one-to-one. The number of sub-carriers is the same as the number of sub-carriers. One sub-carrier is connected to one sub-carrier. The crop environmental information in the sub-carrier is obtained and stored through the sub-carrier through the sub-carrier.

[0025] When a unit carrier storing crop environmental information is transmitted to a retention node, the subordinate group connected to the unit carrier storing crop environmental information is swapped with multiple retention points in the retention node. The retention point is connected to the sub-carrier and the crop environmental information is obtained and stored. The retention point connected to the sub-carrier is used as the subordinate point, and the subordinate point in the retention space is used as the retention point. At the same time, the unit carrier that does not store crop environmental information is transmitted to the position of the corresponding previous retention node.

[0026] If the crop environment information stored in the retention node is inconsistent with the crop environment information in the previous retention node, the unit carrier storing the crop environment information is regarded as an abnormal carrier, and the crop environment information in the abnormal carrier is destroyed to obtain a blank carrier.

[0027] The observable groups of the retention points in the previous retention node and the unit carriers that do not store crop environmental information are swapped, and the crop environmental information stored in the retention points in the previous retention node is stored in the unit carriers that do not store crop environmental information to obtain normal carriers.

[0028] The positions of the normal carrier and the blank carrier are swapped, and the transmission continues until the carrier reaches the irrigation platform.

[0029] In a preferred embodiment, the step of controlling the corresponding irrigation equipment to irrigate crops according to the irrigation plan and providing a real-time irrigation plan includes:

[0030] The irrigation scheme controls the corresponding irrigation equipment to irrigate crops within the sensor's data acquisition range;

[0031] During irrigation, multiple sensors collect real-time crop environmental information and regenerate a new irrigation plan at preset time points.

[0032] The present invention also provides an Internet of Things-based crop irrigation control system, comprising:

[0033] The data acquisition module is used to determine the crop management area information. Multiple sensors are set up within the crop management area to collect crop environmental information, including soil moisture, soil temperature, light intensity, and rainfall.

[0034] The analysis module, connected to the acquisition module, is used to transmit crop environmental information collected by multiple sensors to the irrigation platform, process and analyze the crop environmental information to obtain an irrigation plan, which includes irrigation equipment, irrigation time of the irrigation equipment, and irrigation volume.

[0035] The irrigation module, connected to the analysis module, is used to control the corresponding irrigation equipment to irrigate crops according to the irrigation plan and to provide real-time irrigation plans.

[0036] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0037] This invention collects real-time crop environmental information through multiple sensors during irrigation, and regenerates a new irrigation plan at preset time points. The new irrigation plan is regenerated every certain period of time, and irrigation is carried out according to the new plan. This can irrigate crops more accurately, ensure the stability of crop irrigation, and save water without affecting the normal growth of crops. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1, please refer to Figure 1 As shown in this embodiment, the IoT-based crop irrigation control method includes the following steps:

[0043] S1. Determine the crop management area information, set up multiple sensors within the crop management area, and collect crop environmental information through multiple sensors, including soil moisture, soil temperature, light intensity, and rainfall.

[0044] S2. Transmit crop environmental information collected by multiple sensors to the irrigation platform, process and analyze the crop environmental information to obtain an irrigation plan, which includes irrigation equipment, irrigation time of irrigation equipment and irrigation volume.

[0045] S3. Control the corresponding irrigation equipment to irrigate crops according to the irrigation plan and provide real-time irrigation plan;

[0046] In one embodiment, step S1, which involves determining the crop management area information, setting up multiple sensors within the crop management area, and collecting crop environmental information through the multiple sensors, includes:

[0047] S11. Delineate the crop management area, obtain an image of the crop management area and the location information of the irrigation equipment within the crop management area as the crop management area information, and mark the irrigation equipment in the image.

[0048] S12. Transmit crop management area information and images to the irrigation platform;

[0049] S13. Install multiple sensors within the crop management area, including temperature sensors, humidity sensors, light sensors, and weather sensors, and mark the locations of the sensors in the image on the irrigation platform.

[0050] S14. Collect crop environmental information through multiple sensors;

[0051] As described in steps S11-S14 above, the management area of ​​the crops needs to be determined first. Then, aerial images of the crop management area are obtained through operations such as drones. The location of irrigation equipment within or around the crop management area is also obtained. This information is marked in the collected images, making it easier for managers to directly view the crop irrigation situation. Multiple sensors are set up within the crop management area to collect data on soil moisture, soil temperature, light intensity, and rainfall. This data serves as reference data for irrigation plans within the crop management area. The sensors are also marked in the images, which allows the crop environmental information collected by the sensors to be accurately mapped to the images, resulting in better data mapping.

[0052] In one embodiment, step S2, which involves transmitting crop environmental information collected by multiple sensors to an irrigation platform, processing and analyzing the crop environmental information to obtain an irrigation plan, includes:

[0053] S21. Establish transmission channels between multiple sensors and the irrigation platform, and set up subgroups and multiple retention nodes in the transmission channels;

[0054] S22. The crop environment information collected by multiple sensors is transmitted through the transmission channel. During the transmission process, the crop environment information is protected by the obedience group and multiple retention nodes until the crop environment information is transmitted to the irrigation platform.

[0055] S23. Clean the crop environmental information, mark the cleaned crop environmental information in the image of the corresponding sensor acquisition range, and obtain the current actual water volume and average water consumption of the crop environmental information as the current water volume information.

[0056] S24. Obtain the crop types in the image, and combine the sensor acquisition range corresponding to the current water volume information, the current water volume information, and the water demand of the crop types to formulate the corresponding irrigation equipment, irrigation time of the irrigation equipment, and irrigation volume as an irrigation plan. The irrigation volume is the average irrigation volume per unit irrigation time.

[0057] As described in steps S21-S24 above, the sensor is used to monitor crop environmental information within the crop management area. The sensor has a certain monitoring range; for example, temperature and humidity sensors have specific monitoring ranges. The ground is uneven, and the temperature and humidity differ between sun-facing and shaded land. Therefore, the sensor needs to be set according to these characteristics, resulting in a corresponding acquisition range. The sensor collects crop environmental information within the corresponding acquisition range and transmits this information to the irrigation platform through a transmission channel. Before using the crop environmental information, it needs to be cleaned. The cleaned crop environmental information is then marked in the image within the corresponding sensor acquisition range. This allows the crop environmental information collected by the sensor to be marked in the image, thus obtaining crop environmental information for the entire crop management area. The current actual water volume and average water consumption are obtained from the crop environmental information as current water volume information. The actual water volume includes a comprehensive analysis of humidity and rainfall. The average water consumption is analyzed through temperature and light intensity. The effects of temperature and light intensity on soil moisture consumption are not isolated; there is an interaction between them. For example, under high temperature and sufficient sunlight, plant transpiration will be significantly enhanced, thus increasing the consumption of soil moisture. The estimated evaporation rate of soil moisture under different temperatures and light intensities is used as a reference for subsequent average irrigation amounts. This ensures that irrigation water is delivered slowly, meeting crop needs while reducing natural evaporation and maximizing crop utilization. The average water consumption here refers to the water consumption per unit time affected by ambient temperature and light intensity. Next, the crop types in the image are acquired. Since different crop types have different water requirements, the current water information is analyzed based on the crop types in the image to determine if it meets the needs of those specific crop types. If not, irrigation time and amount can be determined based on the crop type's requirements. Irrigation equipment specific to the sensor's acquisition range is used to obtain an irrigation plan with good crop irrigation performance. This plan allows for remote, fully automatic data acquisition and irrigation without human intervention.

[0058] In one embodiment, step S21, which establishes a transmission channel between multiple sensors and the irrigation platform, and sets up a subsystem and multiple retention nodes in the transmission channel, includes:

[0059] S211. Establish a transmission channel between each sensor and the irrigation platform. Set multiple subordination points in the transmission channel. Associatize the multiple subordination points to obtain a subordination group. The subordination group is located in the network position of the transmission channel close to the sensor. There are two subordination groups in a single transmission channel.

[0060] S212. Set up multiple retention spaces in the transmission channel, set up multiple retention points in the retention spaces to obtain retention nodes, wherein the number of retention points is the same as the number of subordinate points, and the multiple retention points are associated with each other.

[0061] S213. Communication between multiple storage spaces in a single transmission channel;

[0062] As described in steps S211-S213 above, multiple follow-up points are set in the transmission channel. Each follow-up point is a combination of a transmission carrier and a port. The port is connected to the transmission carrier, and subsequent crop environmental information can be obtained through the port and stored in the transmission carrier. The follow-up points can follow the transmission of crop environmental information. Multiple retention nodes are set at intervals in the transmission channel. Each retention node is a storage device added to the transmission channel as a node. This storage device serves as a point in the middle of the transmission channel. Crop environmental information can pass through the retention nodes, which facilitates subsequent security verification of the crop environmental information. The multiple retention nodes are connected to each other to compare data and ensure data security.

[0063] In one embodiment, step S22, which involves transmitting crop environmental information collected by multiple sensors through a transmission channel and ensuring the transmission of crop environmental information is protected by a control group and multiple retention nodes, includes:

[0064] S221. Two unit carriers are set between multiple sensors and transmission channels, wherein the unit carrier includes multiple connected sub-carriers, and the two unit carriers are associated with each other;

[0065] S222. The crop environment information collected by the sensor is randomly stored in one of the unit carriers and randomly distributed in multiple sub-carriers within the unit carrier.

[0066] S223. Both unit carriers are transmitted through the transmission channel. The unit carrier storing crop environmental information is given priority to be put into the transmission channel. The two sub-carriers are connected to the unit carrier one-to-one. The number of sub-carriers is the same as the number of sub-points. One sub-point is connected to one sub-carrier. The crop environmental information in the sub-carrier is obtained through the sub-carrier and stored.

[0067] S224. When the unit carrier storing crop environmental information is transmitted to the retention node, the subordinate group connected to the unit carrier storing crop environmental information is exchanged with multiple retention points in the retention node. The retention point is connected to the sub-carrier and the crop environmental information is obtained and stored. The retention point connected to the sub-carrier is used as the subordinate point, and the subordinate point in the retention space is used as the retention point. At the same time, the unit carrier that does not store crop environmental information is transmitted to the position of the corresponding previous retention node.

[0068] S225. If the crop environment information stored in the retention node is inconsistent with the crop environment information in the previous retention node, the unit carrier storing the crop environment information is regarded as an abnormal carrier, and the crop environment information in the abnormal carrier is destroyed to obtain a blank carrier.

[0069] S226. Swap the obedience groups of the retention points in the previous retention node and the unit carriers that do not store crop environmental information, and store the crop environmental information stored in the retention points in the previous retention node into the unit carriers that do not store crop environmental information to obtain normal carriers.

[0070] S227. Swap the positions of the normal carrier and the blank carrier and continue the transmission until the carrier is delivered to the irrigation platform.

[0071] As described in steps S221-S227 above, two unit carriers are set between each sensor and the transmission channel. Each unit carrier is a virtual machine, and each unit carrier is connected by multiple sub-carriers. Each sub-carrier is a virtual space partitioned within the virtual machine. The two unit carriers are then interconnected. Crop environmental information is stored in one unit carrier (referred to as the first unit carrier), while the other unit carrier does not store data (referred to as the second unit carrier). Both are transmitted together. When the data enters the transmission channel, a connection is established between the first and second unit carriers via a compliance point, and the crop environmental information in the first unit carrier is obtained. The compliance point and the combination of multiple retention points are both virtual machines, and a single compliance point and a single retention point are both single storage points on the virtual machine. In the storage space, connections between virtual machines are made via ports. During transmission, when the first unit carrier passes through a retention node, the second unit carrier will also pass through the previous retention node. (Here, when the first unit carrier passes through the first retention node, the follower point connected to the first unit carrier is swapped with the retention point in the first retention node. The second unit carrier will only pass through the previous retention node if it passes through at least the second retention node.) The first unit carrier can disconnect from the follower group, and the follower group is swapped with the retention point in the retention node passed by the first unit carrier. The follower group is stored in the retention space. Here, the retention point and the follower point are the same, only the names are different for distinction. When the follower group is stored in the retention node... When the crop environmental information in a given node is inconsistent with the crop environmental information in the previous storage node, the unit carrier containing the crop environmental information is designated as an abnormal carrier. The crop environmental information in the abnormal carrier is destroyed to obtain a blank carrier. The units stored in the previous storage node and the unit carriers without stored crop environmental information are swapped. The crop environmental information stored in the previous storage node is then stored in the unit carrier without stored crop environmental information to obtain a normal carrier. The normal carrier and the blank carrier are then swapped in transmission, and transmission continues. In this way, the blank carrier can function as a second unit carrier. The two unit carriers can continuously swap positions when anomalies occur, thus safeguarding the secure transmission of crop environmental information. The process of ensuring the security of crop environmental information is repeated until it is transmitted to the irrigation platform. The irrigation platform receives the crop environmental information and processes and analyzes it. This processing involves data cleaning of the crop environmental information. The analysis process is as follows: Irrigation time and amount are determined based on current water volume and the water requirements of the crop type. The corresponding irrigation equipment is determined based on the sensor data collection range corresponding to the crop environmental information. For example, if the current actual water volume is T1, the average water consumption is T2, and the water requirement of the crop type is T3, and the current actual water volume (T1) is greater than the crop type's water requirement (T3), irrigation is not required immediately. Instead, the corresponding irrigation equipment is activated after time b when T1 - T2 * b = T3.The water requirement T3 for each crop type is the water requirement per unit time. Therefore, after time b, the corresponding irrigation equipment will be turned on, and the irrigation amount will be the average irrigation amount per unit irrigation time, which is the water requirement T3 for the crop type, and thus the irrigation plan.

[0072] In one embodiment, step S3, which involves controlling the corresponding irrigation equipment to irrigate crops according to the irrigation plan and providing a real-time irrigation plan, includes:

[0073] S31. Control the corresponding irrigation equipment to irrigate crops within the sensor acquisition range through the irrigation scheme;

[0074] S32. During the irrigation process, real-time crop environmental information is collected through multiple sensors, and a new irrigation plan is regenerated at preset time nodes.

[0075] As described in steps S31 and S32 above, the irrigation scheme controls the corresponding irrigation equipment to irrigate the crops within the sensor's acquisition range. During the irrigation process, multiple sensors collect real-time crop environmental information, and a new irrigation scheme is regenerated at preset time nodes. The new irrigation scheme is regenerated every certain period of time, and irrigation is carried out according to the new irrigation scheme. This allows for more precise irrigation of crops, ensuring the stability of crop irrigation and preventing any impact on the normal growth of crops.

[0076] Example 2, please refer to Figure 2 As shown, the IoT-based crop irrigation control system described in this embodiment includes:

[0077] The data acquisition module is used to determine the crop management area information. Multiple sensors are set up within the crop management area to collect crop environmental information, including soil moisture, soil temperature, light intensity, and rainfall.

[0078] The analysis module, connected to the acquisition module, is used to transmit crop environmental information collected by multiple sensors to the irrigation platform, process and analyze the crop environmental information to obtain an irrigation plan, which includes irrigation equipment, irrigation time of the irrigation equipment, and irrigation volume.

[0079] The irrigation module, connected to the analysis module, is used to control the corresponding irrigation equipment to irrigate crops according to the irrigation plan and to provide real-time irrigation plans.
