Description

Technical Field

[0001] This invention relates to the field of prevention and control, and more particularly to a red imported fire ant control system based on LoRa technology. Background Technology

[0002] The Latin name for red imported fire ants means "invincible" ant, as they are very difficult to control. Widely distributed, red imported fire ants are among the most destructive invasive species. They are an invasive species in my country. Red imported fire ants are aggressive towards humans and capable of repeated stings. They affect the health and quality of life of people in invaded areas, damage public facilities and electronic equipment, and cause financial losses in communications, medical care, and pest control.

[0003] Existing methods for controlling red imported fire ants require transmitting the monitored data directly to a cloud server for storage after identifying areas where the ants are present. However, in some remote areas where there is no cellular network coverage, it is difficult to transmit the monitored data to a cloud server. Summary of the Invention

[0004] The purpose of this invention is to disclose a red imported fire ant control system based on LoRa technology, which solves the problem of how to transmit red imported fire ant monitoring data to a cloud server in areas without cellular communication network coverage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A red imported fire ant control system based on LoRa technology includes a monitoring module, a collection module, a satellite communication module, and a cloud service module;

[0007] The monitoring module includes a camera and a LoRa communication node. The camera is used to acquire images of red imported fire ants in a designated area. The LoRa communication node is connected to the camera and is used to send the acquired images to the collection module.

[0008] The collection module is used to transmit the live images sent by the LoRa communication node to the satellite communication module;

[0009] The satellite communication module is used to transmit live images to the cloud server module via satellite communication technology;

[0010] The cloud service module is used to perform image recognition processing on live images from the satellite communication module and obtain recognition results.

[0011] Optionally, there can be multiple cameras and LoRa communication nodes, with one LoRa communication node connected to one camera.

[0012] Optionally, multiple LoRa communication nodes can form a wireless communication network through self-organizing networking. The wireless communication network is used to transmit the moving images acquired by the camera to the collection module.

[0013] Optionally, in the wireless communication network, LoRa communication nodes are divided into member nodes and cluster head nodes.

[0014] Optionally, the member node is used to connect to the camera and send the live images acquired by the camera to the corresponding cluster head node;

[0015] The cluster head node is used to transmit the live images sent by member nodes to the collection module.

[0016] Optionally, the cluster head node is also used to connect to a camera and transmit the moving images acquired by the camera to the collection module.

[0017] Optionally, the collection module includes a base station, which is used to receive live images from LoRa communication nodes and transmit the live images to a satellite communication module.

[0018] Optionally, the identification results include the hazard level of red imported fire ants and the corresponding prevention and control strategies.

[0019] In the process of controlling red imported fire ants, this invention first acquires activity images of the ant's activity area using a camera. Then, a LoRa communication node sends the activity images to a collection module. After relaying through the collection module, a satellite communication module transmits the activity images to a cloud server for identification, obtaining the identification results. Compared with existing technologies, this invention can be deployed in areas without cellular communication networks, enabling real-time transmission of activity images. This allows for real-time monitoring of red imported fire ant activity based on these images, facilitating timely implementation of appropriate control strategies. Attached Figure Description

For those skilled in the art, other drawings can be obtained based on the following drawings without creative effort.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figure 1As shown in one embodiment, the present invention provides a red imported fire ant control system based on LoRa technology, including a monitoring module, a collection module, a satellite communication module, and a cloud service module;

[0024] The monitoring module includes a camera and a LoRa communication node. The camera is used to acquire images of red imported fire ants in a designated area. The LoRa communication node is connected to the camera and is used to send the acquired images to the collection module.

[0025] The collection module is used to transmit the live images sent by the LoRa communication node to the satellite communication module;

[0026] The satellite communication module is used to transmit live images to the cloud server module via satellite communication technology;

[0027] The cloud service module is used to perform image recognition processing on live images from the satellite communication module and obtain recognition results.

[0028] In the process of controlling red imported fire ants, this invention first acquires activity images of the ant's activity area using a camera. Then, a LoRa communication node sends the activity images to a collection module. After relaying through the collection module, a satellite communication module transmits the activity images to a cloud server for identification, obtaining the identification results. Compared with existing technologies, this invention can be deployed in areas without cellular communication networks, enabling real-time transmission of activity images. This allows for real-time monitoring of red imported fire ant activity based on these images, facilitating timely implementation of appropriate control strategies.

[0029] LoRa is a low-power local area network (LAN) wireless standard developed by Semtech. It belongs to the category of long-range radio. Its biggest feature is that, under the same power consumption conditions, it can propagate farther than other wireless methods. It achieves a balance between low power consumption and long distance, with a range 3-5 times greater than traditional radio frequency communication at the same power consumption.

[0030] Optionally, there can be multiple cameras and LoRa communication nodes, with one LoRa communication node connected to one camera.

[0031] Specifically, each camera is responsible for shooting in a designated area. Both the camera and the LoRa communication node are powered by batteries, and the camera can be remotely controlled.

[0032] The designated area is the region where red imported fire ants are active.

[0033] Optionally, multiple LoRa communication nodes can form a wireless communication network through self-organizing networking. The wireless communication network is used to transmit the moving images acquired by the camera to the collection module.

[0034] Specifically, since the monitoring area is generally quite large, LoRa communication nodes may not be able to communicate directly with the collection module. By forming a wireless communication network, the monitoring of red imported fire ants is not affected by the communication range of the LoRa communication nodes, thus achieving monitoring over a wider area.

[0035] Optionally, in the wireless communication network, LoRa communication nodes are divided into member nodes and cluster head nodes.

[0036] Optionally, the collection module is used to perform clustering processing on LoRa communication nodes, dividing the LoRa communication nodes into member nodes and cluster head nodes to obtain clustering results.

[0037] Specifically, after obtaining the clustering results, the collection module sends the clustering results to each LoRa communication node. The clustering results contain the identity of each LoRa communication node, allowing the LoRa communication node to determine whether it is a member node or a cluster head node upon receiving the clustering results. If it is a member node, it can also determine which LoRa communication node is its corresponding cluster head node based on the clustering results.

[0038] Optionally, LoRa communication nodes are clustered, including:

[0039] The following function is used to calculate the duration of each clustering result:

[0040] duration n+1 =duration n +vrapar n

[0041] Among them, duration n+1 and duration n These represent the duration of the (n+1)th and nth clustering results, respectively. n Indicates a variable parameter;

[0042] After clustering, the collection module counts down the effective duration. After the countdown ends, clustering is performed again.

[0043] In existing technologies, a fixed clustering period is generally used for clustering processing. However, since the transmission of moving images is not periodic (red imported fire ants are not active all day), using a fixed clustering period wastes the power of LoRa communication nodes. Therefore, this invention calculates the effective duration by using variable parameters, so that the effective duration of the clustering result adapts to the actual data transmission situation, which helps to avoid excessively frequent clustering and saves the power of LoRa communication nodes.

[0044] Optional, vraparn Obtain it using the following method:

[0045] Let t be the effective time and the ineffective time of the nth clustering result. start,n and t end,n ;

[0046] Calculate the time period [t] start,n , t end,n Within [the specified area], the communication state coefficients of the wireless communication network:

[0047]

[0048] Where comstacoef represents the communication state coefficient, λ1 and λ2 represent weight parameters, and headnode represents the time period [t]. start,n , t end,n The set of cluster head nodes within a [], where num represents the total number of elements contained in the headnode, and nodecusm i Indicates that cluster head node i is in the time period [t] start,n , t end,n The power consumed within the time period [t], where coefst represents the set power consumption reference value, and datatrs represents the power consumption of the wireless communication network within the time period [t]. start,n , t end,n The number of active images forwarded within the specified range, where datast represents a reference value for the number of active images forwarded.

[0049] If comstacoef is greater than the set coefficient threshold, then vrapar n The calculation function is:

[0050] vrapar n =-stper×Φ

[0051] If comstacoef is less than or equal to the set coefficient threshold, then vrapar n The calculation function is:

[0052] vrapar n =stper×Φ

[0053] Where stper represents the set time length, and Φ represents the set control coefficient.

[0054] In the above implementation, vrapar nThe calculation results are related to the data transmission during the effective period of the nth clustering result. The more uneven the power consumption and the greater the number of forwarded active images, the greater the communication state coefficient. Therefore, in order to avoid the power consumption of a single cluster head node being too fast, this invention shortens the effective period of the clustering result. The more uniform the power consumption and the less the number of forwarded active images, the smaller the communication state coefficient. Therefore, this invention extends the effective period of the clustering result.

[0055] Optionally, the member node is used to connect to the camera and send the live images acquired by the camera to the corresponding cluster head node;

[0056] The cluster head node is used to transmit the live images sent by member nodes to the collection module.

[0057] Optionally, the cluster head node is also used to connect to a camera and transmit the moving images acquired by the camera to the collection module.

[0058] Optionally, the collection module includes a base station, which is used to receive live images from LoRa communication nodes and transmit the live images to a satellite communication module.

[0059] Optionally, the identification results include the hazard level of red imported fire ants and the corresponding prevention and control strategies.

[0060] Optionally, the cloud service module includes a cloud computing unit, a storage unit, and a client unit.

[0061] The cloud computing unit is used to perform image recognition processing on moving images and calculate the number of red imported fire ants appearing in the moving images;

[0062] The storage unit is used to store control strategies for red imported fire ants at different levels of hazard.

[0063] The cloud computing unit is also used to calculate the average number of red imported fire ants appearing in the active images corresponding to each specified area within a set time period; the corresponding hazard level is determined based on the average value. The higher the average value, the greater the hazard level.

[0064] The cloud computing unit sends the hazard level and corresponding prevention and control strategy to the client unit;

[0065] The client unit is used to display the hazard level and the corresponding prevention and control strategy.

[0066] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
