[0002] In modern agriculture, forestry and animal husbandry, rodents have become an object that urgently needs to be managed and controlled. At present, rodent monitoring mainly relies on traditional means such as chemical drugs and mechanical mouse traps. Although they can play a certain role in management, drugs also cause great harm to various crops and plants, and mechanical mouse traps are labor-intensive and inefficient. In addition, they cannot effectively monitor and identify specific details such as the type and age of rodents in the monitoring area, and cannot form a scientific and effective basis for rodent control. Summary of the invention

[0004] The technical solution of the present invention is: a rat monitoring device, including a main box, wherein the main box includes a rat luring channel, a rat expelling channel and a rat killing chamber located therebetween, the rat luring channel has a rat luring entrance connected to the outside of the main box and a rat luring exit connected to the rat killing chamber, the rat expelling channel has a rat expelling exit connected to the outside of the main box and a rat expelling entrance connected to the rat killing chamber, the rat killing chamber has a first sensing module for sensing rats entering the rat killing chamber, the top of the rat killing chamber has an image acquisition module for taking pictures of the rat killing chamber and a baiting module for putting rat poison in the rat killing chamber, and the rat killing chamber has a first sensing module for sensing rats entering the rat killing chamber. The bottom has a movable bottom plate and a driving module that drives the bottom plate to rotate toward the mouse discharge entrance. The bottom plate has a weighing module for weighing mice entering the mouse killing chamber. The first sensing module, the image acquisition module, the bait throwing module, the driving module and the weighing module are all connected to the control module in communication. The control module controls the image acquisition module and the bait throwing module to start based on the signal sent by the first sensing module, controls the driving module to start based on the set time after the bait throwing module action is completed, and generates the mouse damage information required by the user based on the information collected by the image acquisition module and the weighing module. The mice are lured into the mouse killing chamber by setting a mouse luring channel, and rat poison is put into the mouse killing chamber through the bait throwing module on the top of the mouse killing chamber to poison the mice. Under the driving action of the driving module, the bottom plate is turned over to discharge the mice from the mouse discharge channel to the main box body, thereby achieving the control effect of the monitoring area. At the same time, the image acquisition module and the weighing module in the mouse killing chamber obtain the image information and weight information of the mice entering the mouse killing chamber, and the control module generates the mouse damage information required by the user as a scientific and effective basis for mouse damage prevention and control.

[0005] A film pressure sensor is attached to the side of the bottom plate corresponding to the bait feeding module, which is used to sense the mice moving around the positive projection area of ​​the bait feeding module. The film pressure sensor is connected to the control module for communication, and the control module controls the start of the drive module based on the duration of the signal sent by the film pressure sensor. The film pressure sensor can sense the mice entering the bait feeding area to eat, and the duration of the sensing is set to form an OR logic with the set time after the bait feeding module is activated, that is, when either of the two times is reached, the drive module can be controlled to run, thereby more effectively confirming the process of mice eating rat poison and shortening the mouse's stay time in the deratization chamber as much as possible.

[0010] A high-voltage grid is laid on the inner wall of the mouse-repelling channel, and the control module is electrically connected to the high-voltage grid via a booster unit. The high-voltage grid can increase the mortality rate of mice, and can continue to ensure the mouse-killing effect of the device after the mouse poison in the baiting module is used up.

[0011] The technical solution of the present invention also includes a method for monitoring rat conditions, which uses the above-mentioned rat condition monitoring device to monitor rat conditions in a monitoring area, and includes the following steps: S1, the control module receives a signal from the first sensing module, controls the image acquisition module and the bait feeding module to start, and obtains image information collected by the image acquisition module and weight information collected by the weighing module; S2, using a basic model for mouse recognition based on a convolutional neural network to analyze the image information to obtain mouse species information, and obtaining mouse age information based on the species information and the weight information; S3, obtaining the rodent damage situation in the monitoring area according to the historical number information, the age information and the species information of the rats in the monitoring area, wherein the rodent damage situation includes the population size of the rats in the monitoring area; S4, the control module controls the driving module to move and flip the bottom plate within the set time, and the rats are discharged from the rat discharge channel.

[0019] like Figure 3 As shown, the deratization chamber 3 has a first sensing module 8 for sensing mice entering the deratization chamber 3. Specifically, the first sensing module 8 includes an infrared transmitting sensor and an infrared receiving sensor. The infrared transmitting sensor and the infrared receiving sensor are respectively fixed on the left and right side walls of the deratization chamber 3. The mice entering the deratization chamber 3 block the infrared light emitted by the infrared transmitting sensor, and then the infrared receiving sensor sends a related signal. The top of the deratization chamber 3 has an image acquisition module 5 for taking pictures of the deratization chamber 3 and a baiting module 6 for putting rat poison in the deratization chamber 3. Specifically, the image acquisition module 5 includes a high-definition camera and its corresponding fill light, as shown in FIG. Figure 6 As shown, the bait feeding module 6 includes a bait bin 601 fixed in the main box 1 and an automatic feeder 602 fixed below the bait bin 601. A feeding port 303 is provided on the top of the deratization bin 3. The inlet of the automatic feeder 602 is connected to the outlet of the bait bin 601. The outlet of the automatic feeder 602 extends into the feeding port 303. The automatic feeder 602 is an impeller feeder, which is driven by a motor to intermittently deliver rat poison to the outlet. Preferably, in order to ensure the accuracy of feeding, an angle encoder 603 for recording the rotation angle of the impeller is also installed on the impeller feeder. Figure 4 As shown, the bottom of the deratization chamber 3 has a movable bottom plate 301 and a driving module 7 for driving the bottom plate 301 to rotate toward the mouse discharge entrance. The bottom plate 301 has a weighing module 9 for weighing the mice entering the deratization chamber 3. In order to prevent the mice discharged from the mouse discharge channel 4 from accumulating on one side of the main box body 1, as shown in FIG. Figure 4 and Figure 5 As shown, there are two mouse-exiting channels 4, which are symmetrically arranged and fixed at the bottom of the mouse collecting box. Specifically, the driving module 7 includes a rotating shaft 703 located between the two mouse-exiting channels 4 and extending axially, bearing seats 702 rotatably installed at both ends of the rotating shaft 703, and a servo 701 fixed on any bearing seat 702 and connected to the rotating shaft 703.

[0020] The first sensing module 8, the image acquisition module 5, the bait throwing module 6, the drive module 7 and the weighing module 9 are all connected to the control module for communication. In order to ensure the continuous operation of the monitoring device, a solar panel 12 is installed on the top of the main box 1, and a solar control module and a battery are arranged in the main box 1. The solar panel 12 is electrically connected to the battery via the solar control module for charging the battery, and the battery is electrically connected to each module for supplying power to each module; the control module controls the image acquisition module 5 and the bait throwing module 6 to be turned on based on the signal sent by the first sensing module 8, and controls the drive module 7 to be turned on based on the set time after the bait throwing module 6 completes the action. Preferably, the set time is defined as the duration t1, and its numerical range is determined based on multiple tests. Specifically in this embodiment, t1=3-5min; and the rodent damage information required by the user is generated based on the information collected by the image acquisition module 5 and the weighing module 9.

[0021] Place multiple rat monitoring devices in the monitoring area, and the rats in the monitoring area enter the rat killing chamber 3 through the rat attracting channel 2. In order to further improve the rat attracting effect of the device, Figure 3 As shown, a first hollow portion 203 is provided on the outer wall of the mouse luring channel 2 near the mouse luring entrance and the mouse luring exit, and a second hollow portion 302 is provided on the top of the mouse killing chamber 3. Mouse attracting spices for emitting mouse attracting fragrance are laid on the outer sides of the first hollow portion 203 and the second hollow portion 302. At the same time, the second hollow portion also serves as the light-emitting port of the fill light in the image acquisition module 5.

[0022] In order to prevent mice that have entered the mouse killing bin 3 from escaping, the mouse luring channel 2 is an inclined channel extending downward in a direction away from the mouse killing bin 3, and the mouse luring entrance and the mouse luring exit are respectively movably connected with a first mouse guard plate 201 and a second mouse guard plate 202. Specifically, the first mouse guard plate 201 is rotatably installed on the inner side of the mouse luring channel 2, and an outer guard plate that limits the outward movement of the first mouse guard plate 201 is installed on the inner side of the mouse luring channel 2 corresponding to the mouse luring entrance. The second mouse guard plate 202 is rotatably installed in the mouse killing bin 3 via a hinge, and the size of the second mouse guard plate 202 is larger than the size of the total mouse luring exit. Furthermore, in order to facilitate mice to climb in the mouse luring channel 2, anti-slip grooves are provided on the bottom plate 301 of the mouse luring channel 2. In order to prevent mice from entering the main box 1 in the opposite direction through the mouse row channel 4, a third mouse guard plate 401 is movably connected at the mouse row exit. Specifically, the third mouse guard plate 401 is rotatably installed on the mouse row channel 4 outside the mouse row exit via a rotating rod, and the size of the third mouse guard plate 401 is larger than the size of the mouse row exit.

[0023] The baiting module 6 on the top of the deratization chamber 3 feeds rat poison into the deratization chamber 3 to kill the rats. The bottom plate 301 is flipped under the driving action of the driving module 7 to discharge the rats out of the main box 1 through the rat discharge channel 4, thereby achieving the control effect on the monitored area. At the same time, the image acquisition module 5 and the weighing module 9 in the deratization chamber 3 obtain the image information and weight information of the rats entering the deratization chamber 3, and the control module generates the rodent pest information required by the user as a basis for scientific and effective rodent pest control.

[0024] Further preferably, Figure 4 As shown, a film pressure sensor 10 is attached to the side of the bottom plate 301 corresponding to the bait feeding module 6, which is used to sense mice moving around the positive projection area of ​​the bait feeding module 6. The film pressure sensor 10 is communicated with the control module. The control module controls the start of the drive module 7 based on the duration of the signal sent by the film pressure sensor 10. The above time is defined as the duration t2, and its numerical range is determined based on multiple tests. Specifically in this embodiment, t2=30s-1min; the set duration t2 and the duration t1 after the action of the bait feeding module 6 form an OR logic, that is, when either of the two times is reached, the operation of the drive module 7 can be controlled, thereby more effectively confirming the process of mice eating rat poison and shortening the mouse's stay time in the deratization chamber 3 as much as possible.

[0025] Further preferably, Figure 6 As shown, a limit sensor 604 is installed on the wall of the bait bin 601 to monitor the amount of rat poison in the bait bin 601, so as to notify the maintenance personnel to replenish the rat poison through the control module when the amount is insufficient. Figure 5 As shown, in order to ensure the rodent control effect, a high-voltage power grid 11 is laid on the inner wall of the rodent control channel 4. The control module is electrically connected to the high-voltage power grid 11 via a boost unit. The high-voltage power grid 11 increases the mortality rate of mice, and the rodent control effect of the device can continue to be guaranteed after the rat poison in the baiting module 6 is used up. In order to ensure the safety of the device, the rodent control channel 4 is made of insulating material.

[0026] Using the above-mentioned rodent monitoring device to monitor rodents in a designated monitoring area includes the following steps: S1. The control module receives the signal from the first sensing module 8, controls the opening of the image acquisition module 5 and the bait feeding module 6, and obtains the image information collected by the image acquisition module 5 and the weight information collected by the weighing module 9. The image taken by the image acquisition module 5 will be transmitted to the image processing unit in the control module. The image processing unit uses the edge monitoring algorithm to pre-process the image in the photo, quickly locate and crop out the mouse area to reduce background interference.

[0027] S2, using a basic model for mouse recognition based on a convolutional neural network to analyze the image information, using a feature matching algorithm to obtain the type information of the mouse, and the data processing unit in the control module to obtain the age information of the mouse based on the type information and the weight information; The steps for constructing the basic model for rodent identification are as follows: S201: Select a supervised pre-training algorithm to pre-train the initialized deep learning model, thereby obtaining a pre-trained deep learning network model; S202: Introducing the concept of model compression and acceleration, building a rodent monitoring network based on deep learning, reducing the distribution difference between training data and test data, and enabling the trained model to have excellent transfer performance on the test set; S203: Based on the idea of ​​model compression and acceleration, a rodent segmentation network is constructed. This network integrates a deep convolutional network and a grouped convolutional network, and uses layered perception and deep learning to segment and predict each pixel, achieve instance grouping, and finally obtain the segmentation results of each part of the rodent; S204: using the pre-trained deep learning model and the rodent monitoring data set to train the constructed rodent monitoring network and optimize network parameters, thereby obtaining a rodent monitoring network with optimized parameters; S205: using the pre-trained deep learning model and the mouse grouping data set, training the constructed mouse segmentation network, optimizing network parameters, and obtaining a mouse segmentation network with optimized parameters; S206: By introducing the idea of ​​model compression and acceleration, multimodal deep learning, and deep autoencoder clustering, a mouse classification network is constructed based on the unsupervised learning model; S207: using the rodent classification data set to train the constructed deep learning rodent classification network, optimizing network parameters, and obtaining a rodent classification network with optimized parameters; S208: Building a deep learning mouse super-resolution reconstruction network based on zero-shot unsupervised method and generative adversarial network; S209: Using the mouse super-resolution reconstruction dataset to train the constructed mouse super-resolution reconstruction network to obtain a mouse super-resolution reconstruction dataset with optimized parameters.

[0028] Among them, obtaining the age information of the mouse based on the species information and the weight information includes: obtaining growth curves corresponding to different types of mice, the growth curves are used to characterize the mapping relationship between the age information and weight information of different types of mice, and obtaining the age information of the mouse according to the species information, the weight information and the growth curve.

[0029] Taking the house mouse as an example, the following table shows the research data on the growth curve of the house mouse. The growth curve of house mouse is obtained from the data in the table. Figure 7 As shown, with reference to the growth curve, the age range of the house mouse identified in the present monitoring device is predicted.

[0030] S3, obtaining the rodent damage situation in the monitoring area according to the historical number information, the age information and the species information of the rats in the monitoring area, wherein the rodent damage situation includes the population size of the rats in the monitoring area, and the population size represents the population size of all rodents in the monitoring area; Among them, the maximum carrying capacity of rats in the monitoring area is obtained according to the historical quantity information, and the maximum carrying capacity represents the number of all rodents; the first number of rats in the monitoring area is predicted based on the maximum carrying capacity and the constructed population growth model, and the first number is used to characterize the population size of rats in the monitoring area; the population growth model is used to predict the number of rats at different times, and its formula is: ; Where P(t) is the number of rats at time t, K is the maximum carrying capacity of rats in the monitoring area, r is the growth rate, and t0 is the midpoint time of the population growth curve.

[0031] For example, the monitoring device is deployed in a certain farming and pastoral area in the north. The maximum carrying capacity K of mice in the area is 500, the growth rate r=0.1 / month, and the midpoint time of the population growth curve is t0=10. We predict that the mouse population at t=20 months will be P(20)=365. Based on this number and according to the distribution of different types of mice of different age groups identified and analyzed by the monitoring device, the specific rodent damage situation in the area at t=20 months is obtained in proportion.

[0032] S4, after the duration of the self-baiting module 6 is completed and reaches t1 or the duration of the control module receiving the signal from the film pressure sensor 10 reaches t2, the control module controls the driving module 7 to operate and flip the bottom plate 301, and the mice are discharged from the mouse exclusion channel 4. Further preferably, while the control driving module is operating, the control module energizes the high-voltage power grid 11 on the mouse exclusion channel 4 through the boost module to enhance the rodent extermination effect.

[0033] Through the above monitoring methods, the distribution of rat species in different areas (such as cities, rural areas, farmlands, warehouses, etc.) can also be analyzed to understand whether a specific area is infested by a specific type of rat; based on the age information of the rats, possible future trends in rat infestation can also be predicted, especially the identification of abnormal age distribution of rats. For example, an increase in the proportion of elderly rats may mean that the living environment of rats in the area has deteriorated or there is a shortage of food, thereby providing a scientific basis for predicting rat infestation.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principle of the present invention shall be included in the protection scope of the present invention.
