Description

Technical Field

[0001] This invention relates to the field of animal husbandry monitoring technology, specifically a monitoring system for laboratory animal breeding cages. Background Technology

[0002] In the field of laboratory animal husbandry, traditional monitoring methods typically involve manual, close-range mobile monitoring or remote observation using cameras installed at the breeding site. When using manual mobile monitoring, the frequent approach and passage of personnel can easily attract, disturb, or agitate the animals, compared to remote camera observation. These factors indirectly affect the fluctuation of experimental data. While high-mounted cameras offer wide coverage, their limited viewing angles and difficulty in accurately understanding changes in animal condition compared to close-range manual monitoring result in limited information collection. These traditional monitoring methods are labor-intensive, prone to influencing factors affecting animal husbandry, and limited in information collection, hindering the improvement of data accuracy and comprehensive information gathering. Summary of the Invention

[0003] To address the aforementioned problems of existing animal husbandry monitoring methods, such as high labor costs, potential for factors affecting animal husbandry, and limited information collection, the technical solution adopted by this invention is as follows: A monitoring system for laboratory animal breeding cages includes a structural cage frame for accommodating animals, the structural cage frame having a plurality of breeding cages for placing animals, the monitoring system further including an information acquisition device for collecting breeding information and a monitoring terminal for storing and processing breeding information, the information acquisition device collecting breeding information corresponding to the breeding cages and transmitting the collected breeding information back to the monitoring terminal for statistical processing.

[0004] As described above, the experimental animal breeding cage monitoring system further includes a device gateway 9 for transmitting information back. The information acquisition device transmits the breeding information back to the monitoring terminal via the device gateway 9 using either wired or wireless transmission. The wireless transmission employs at least one of the following wireless transmission methods: Laser signal transmission; Infrared signal transmission; BLE signal transmission; ZigBee signal transmission; Radio frequency signal transmission; Bluetooth signal transmission; Wi-Fi signal transmission.

[0005] As described above, in a laboratory animal breeding cage monitoring system, the bottom of the cage tray used to place the animal is provided with a weight sensor for detecting changes in the animal's weight. Several weight sensors arranged in different breeding cages are respectively connected to the information acquisition device to transmit data on changes in animal weight, or several weight sensors arranged in the same breeding cage are respectively connected to the information acquisition device to transmit data on changes in animal weight.

[0006] As described above, in a laboratory animal breeding cage monitoring system, the breeding cage is equipped with a first camera unit for acquiring images of the animals inside. After acquiring the images of the animals inside, the first camera unit transmits the image information back to the monitoring terminal via wired or wireless transmission. The monitoring terminal compares animal images collected at different times to calculate the animal's activity time and stillness time.

[0007] As described above, in a laboratory animal breeding cage monitoring system, the information acquisition device includes a movable mobile acquisition device, which has a second camera unit for identifying and acquiring information. The breeding information includes tag information located on the outside of the breeding cage. The mobile acquisition device approaches the corresponding breeding cage and acquires the corresponding tag information. The tag information can be an electronic tag or a physical tag.

[0008] As described above, in a laboratory animal breeding cage monitoring system, the mobile acquisition device includes a slide rail assembly mounted on the structural cage frame and a track acquisition device mounted on the slide rail assembly. The guide rail of the slide rail assembly is continuously laid along the length direction of the structural cage frame. The track acquisition device is mounted on a slider of the slide rail assembly and moves along the length direction of the guide rail. A second camera unit is located at the track acquisition device and is positioned facing the breeding cage.

[0009] As described above, in a laboratory animal breeding cage monitoring system, the track collector has a collection cantilever that can be raised and lowered in a vertical direction. The second camera unit is located on the collection cantilever. The collection cantilever is equipped with a lifting mechanism for driving the lifting and lowering movement. The lifting mechanism includes a first drive motor and a first transmission structure. The first transmission structure can be a gear transmission, a pulley transmission, or a sprocket transmission.

[0010] As described above, in a monitoring system for experimental animal breeding cages, the mobile data acquisition device includes a motorized data acquisition unit that can move on the ground. The moving mechanism at the bottom of the motorized data acquisition unit can be a roller-type moving mechanism or a tracked moving mechanism to drive the motorized data acquisition unit to move linearly or turn in the horizontal direction. The second camera unit is installed on the motorized data acquisition unit to identify and acquire breeding information.

[0011] As described above, in a laboratory animal breeding cage monitoring system, the motorized data acquisition device includes an upper body and a lower body. The second camera unit is mounted on a second lifting mechanism on the upper body, and the second lifting mechanism drives the second camera unit to move up and down in the vertical direction.

[0012] As described above, in a laboratory animal breeding cage monitoring system, the motorized data collector further includes a steering mechanism. The steering mechanism is installed between the upper body and the lower body and drives the upper body to rotate in a horizontal circumference. The steering mechanism includes a steering drive motor and a steering transmission structure. The steering transmission structure can be a gear drive, a belt drive, or a sprocket drive.

[0013] The beneficial effects of this invention are as follows: This invention employs information acquisition equipment to remotely monitor and collect breeding information of corresponding animals. The information is then stored and statistically processed through a monitoring terminal. This reduces the increased costs caused by manual intervention and minimizes disturbance to the animals caused by human intervention. Furthermore, it improves the convenience of information collection and avoids errors such as omissions, miscounts, and duplicates in statistical recording caused by manual recording. This provides a complete automated monitoring solution for experimental data and animal feeding, which helps improve the accuracy of experimental data and the completeness of information collection.

[0024] Example 1 Figures 1 to 7 This embodiment provides a monitoring system for laboratory animal breeding cages, including a structural cage frame 1 for accommodating animals, and a plurality of breeding cages 2 on the structural cage frame 1 for placing animals. The monitoring system also includes an information acquisition device for collecting breeding information and a monitoring terminal 3 for storing and processing breeding information. The information acquisition device collects breeding information on the corresponding breeding cages 2 and transmits the collected breeding information back to the monitoring terminal 3 for statistical processing.

[0025] Specifically, in this embodiment, the structural cage frame 1 is the frame used by the monitoring system to place the breeding cage 2 and install and fix components. The structural cage frame 1 can be formed by splicing together several round tubes, square tubes, and other profiles. The breeding cage 2 is a hollow cage structure for animals to live in during the breeding period. The breeding cage 2 can be formed by weaving several thin iron wires to form a wire mesh structure cage with six sides open (its bottom has a multi-hole hollow structure). The information acquisition device is used by the monitoring system to collect breeding information of the animals during the breeding period. The breeding information includes, but is not limited to, the species, number, weight, body temperature, heart rate, activity frequency, feed amount, and environmental parameters such as temperature, humidity, and light cycle of the animals. The information acquisition device can use any of the existing temperature and humidity sensors, weight sensors, biosensors, etc. to collect the above-mentioned breeding information, or it can use a combination of two or more sensors to collect the above-mentioned breeding information. The monitoring system also includes a device gateway 9 for transmitting information back. The breeding information collected by the information acquisition device is transmitted back to the monitoring terminal 3 through the device gateway 9 via wired or wireless transmission. The monitoring terminal 3 stores, records, statistically analyzes, centrally displays, and tabulates the breeding information. Staff can adjust the feeding strategy for the farmed animals based on the statistically processed breeding information and experimental objectives, making it convenient for staff to operate and use.

[0026] This invention employs information acquisition equipment to remotely monitor and collect breeding information of corresponding animals, which is then stored and statistically processed through monitoring terminal 3. This reduces the increased costs caused by manual intervention and minimizes disturbance to the animals caused by human intervention. Furthermore, it improves the convenience of information collection and avoids errors such as omissions, miscounts, and duplicates in statistics caused by manual recording. This provides a complete automated monitoring solution for experimental data and animal feeding, which is beneficial to improving the accuracy of experimental data and the completeness of information collection.

[0027] Furthermore, in some embodiments, the information acquisition device transmits the aquaculture information back to the monitoring terminal 3 via the device gateway 9 through wired or wireless transmission. Preferably, the information acquisition device transmits the aquaculture information wirelessly. The wireless transmission adopts at least one of the following wireless transmission methods: laser signal transmission, infrared signal transmission, BLE signal transmission, ZigBee signal transmission, radio frequency signal transmission, Bluetooth signal transmission, or Wi-Fi signal transmission. The monitoring terminal 3 can preset an electronic spreadsheet, electronic list, or database according to the aquaculture cage number to arrange and store the received aquaculture information, so that staff can call the information at any time to provide a basis for adjusting the aquaculture strategy or checking the aquaculture process.

[0028] Furthermore, in some embodiments, the bottom of the cage tray 24 used to place the animal in the breeding cage 2 is provided with a weight sensor 21 for detecting changes in the animal's weight. Several weight sensors 21 arranged in different breeding cages 2 are respectively connected to an information acquisition device to transmit data on changes in the animal's weight, or several weight sensors 21 arranged in the same breeding cage 2 are respectively connected to an information acquisition device to transmit data on changes in the animal's weight. The weight sensors 21 can be arranged at the bottom positions of multiple different breeding cages 2, or they can be arranged at different bottom positions of the same breeding cage 2 (preferably at the bottom corners and the middle part). The cage 24 is equipped with a structure with several through holes for animal feces to fall through, or a mesh structure for animal feces to fall through, reducing the impact of feces accumulation on the monitoring results. The weight sensor 21 can be connected to the information acquisition device to transmit the continuous increase or decrease of animal weight change per unit time back to the monitoring terminal 3 for recording and statistical processing. Alternatively, an electronic storage unit can be set on the tag information 23 of the cage 2 for short-term storage per unit time (such as 12 hours, 24 hours or 48 hours) and can be identified and acquired by an external mobile acquisition device.

[0029] Furthermore, in some embodiments, the breeding cage 2 is equipped with a first camera unit 22 for acquiring images of the animals inside. The first camera unit 22 is an industrial camera and its supporting industrial vision recognition software. The first camera unit 22 is preferably installed at the top center of the breeding cage 2, so that the shooting range can more comprehensively cover the activity space inside the cage. After the first camera unit 22 acquires images of the animals inside, it transmits the image information back to the monitoring terminal 3 by wired or wireless transmission. The monitoring terminal 3 compares and processes the animal images collected at different times through visual image processing software to count the animal's activity time and still time, or the staff can monitor and inspect the animal breeding situation at irregular intervals.

[0030] Example 2 Figures 1 to 7This embodiment provides a monitoring system for laboratory animal breeding cages. The information acquisition device includes a movable mobile acquisition device 4. In this embodiment, the mobile acquisition device 4, independent of the external structure of the cage frame 1 and / or mounted on the cage frame 1, collects and transmits breeding information. The mobile acquisition device 4 has a second camera unit 41 for identifying and acquiring information. The second camera unit 41 is an industrial camera and its supporting industrial vision recognition software. The breeding information includes tag information 23 located on the outside of the breeding cage 2. The mobile acquisition device 4 can move on the ground of the breeding site and approach the corresponding breeding cage 2 on the structural cage frame 1. The second camera unit 41 performs visual recognition on the tag information 23 on the breeding cage 2 and acquires the tag information 23 corresponding to the breeding cage 2. The tag information 23 can be an electronic tag or a physical tag. The physical tag is a waterproof, rigid sticky note or a matte flat board. The physical tag can use a graphic code such as a QR code or barcode as the tag identification code. The physical tag is placed on the outside of the breeding cage 2 by pasting or inserting. On the side, the second camera unit 41 can directly identify or scan the electronic tag. The electronic tag can be an electronic code in the form of NFC, UWB, integrated circuit chip, etc., as the tag identification code. The physical electronic component of the electronic tag is placed on the outer side of the breeding cage 2 by pasting or plugging it in. The mobile acquisition device 4 moves towards the breeding cage 2 with an electronic identification sensor and performs electronic identification interaction. The tag information 23 includes, but is not limited to, the species, category, quantity, single feed amount, breeding cycle, breeding days, breeding batch, etc. of the animals in the cage. When the breeding cage 2 is equipped with a sensor, the data stored inside the sensor can be collected by the mobile acquisition device 4 through the tag information 23. For example, the continuous increase or decrease in the animal's weight change within a unit time interval of the weight sensor is converted into an electronic code and obtained by the mobile acquisition device 4 after identifying the electronic tag, or converted into an electronic code and obtained from the information acquisition device after the mobile acquisition device 4 identifies the physical tag. The staff prepares and sets the breeding cage 2 in advance according to the batch of animals raised, so as to facilitate the breeding management.

[0031] Furthermore, in some embodiments, the mobile acquisition device 4 includes a slide rail assembly 5 mounted on the structural cage 1 and a track collector 6 mounted on the slide rail assembly 5. In this embodiment, the mobile acquisition device 4 is a track collector 6 mounted on the structural cage 1. The guide rail 51 of the slide rail assembly 5 is continuously laid along the length direction of the structural cage 1. The track collector 6 is mounted on the slider 52 of the slide rail assembly 5. The slide rail assembly 5 drives the track collector 6 to move back and forth along the length direction of the guide rail 51 by means of motor-driven screw transmission or gear and rack transmission. An encoder can be installed on the drive motor to improve the positioning accuracy of the movement. The second camera unit 41 is located on the track collector 6 and is set towards the breeding cage 2. The track collector 6, with the second camera unit 41, collects breeding information for each breeding cage 2 within the movement range to count the breeding situation of each breeding cage 2 every day. The collected breeding information is transmitted back to the monitoring terminal 3 via the information acquisition device through the device gateway 9 in the form of wired or wireless transmission.

[0032] Furthermore, in some embodiments, the guide rails 51 of the slide rail assembly 5 can be respectively arranged on the top and bottom of the outer peripheral side of the structural cage 1. The track collector 6 has a collection cantilever 61 that can be raised and lowered in the vertical direction. The upper end of the collection cantilever 61 is mounted on a slider 52 near the top guide rail 51 on the outer peripheral side of the structural cage 1, and the lower end of the collection cantilever 61 is mounted on a slider 52 near the bottom guide rail 51 on the outer peripheral side of the structural cage 1. The collection cantilever 61 is equipped with a lifting mechanism 62 for driving the second camera unit 41 to move up and down. The lifting mechanism 62 includes a first drive motor and a first transmission structure. The first transmission structure can be a combination of screw drive, gear drive, pulley drive, or sprocket drive and slide rail slider. The first drive motor drives the second camera unit 41 to rise or fall vertically via the first transmission structure. The slide rail assembly 5 drives the track collector 6 to move back and forth along the length of the guide rail 51 by means of motor-driven screw drive or gear rack drive, so as to realize the movement and positioning acquisition of the second camera unit 41 on the outer periphery of the structural cage 1.

[0033] Furthermore, in some embodiments, the mobile acquisition device 4 includes a motorized acquisition unit 7 that can move on the ground. In this embodiment, the mobile acquisition device 4 is a motorized acquisition unit 7 that can move on the ground of the breeding site independently of the structural cage 1. The moving mechanism 71 at the bottom of the motorized acquisition unit 7 can be a roller-type moving mechanism or a track-type moving mechanism to drive the motorized acquisition unit 7 to move linearly or turn in the horizontal direction. The motorized acquisition unit 7 can collect breeding information on multiple adjacent structural cages 1 through the moving mechanism 71. A single motorized acquisition unit 7 can expand the collection range and can replace manual inspection of the breeding situation. The second camera unit 41 is installed on the motorized acquisition unit 7 to identify and collect breeding information. The motorized acquisition unit 7, with the second camera unit 41, collects breeding information on each breeding cage 2 within the moving range to count the breeding situation of each breeding cage 2 every day. The collected breeding information is transmitted back to the monitoring terminal 3 via the device gateway 9 installed on the motorized acquisition unit 7 in a wired or wireless manner.

[0034] Furthermore, in some embodiments, the motorized data collector 7 includes an upper body 72 and a lower body 73. The second camera unit 41 is mounted on the second lifting mechanism 75 of the upper body 72. The second lifting mechanism 75 includes a second drive motor and a second transmission structure. The second transmission structure can be a combination of screw drive, gear drive, pulley drive, or sprocket drive and slide rail slider. The second lifting mechanism 75 drives the second camera unit 41 to move up and down in the vertical direction, so that the second camera unit 41 can rise or fall in the height direction on the motorized data collector 7, and can collect breeding information from the outside of the breeding cage 2 at different height positions.

[0035] Furthermore, in some embodiments, the motorized collector 7 also includes a steering mechanism 74. The steering mechanism 74 is installed between the upper body 72 and the lower body 73 and drives the upper body 72 to rotate horizontally. The motorized collector 7 can carry the second camera unit 41 to collect aquaculture information from each aquaculture cage 2 within its movement range through the steering mechanism 74, reducing the need for bottom movement and improving movement stability. The steering mechanism 74 includes a steering drive motor 741 and a steering transmission structure 742. The steering transmission structure 742 can be used in combination with a screw drive, gear drive, pulley drive, or sprocket drive and a turntable bearing. When the motorized collector 7 moves in the passage between two adjacent structural cage frames 1... At the same time, the motorized data collector 7 can collect breeding information from the two structural cages 1 separately through the steering mechanism 74 and the second lifting mechanism 75, reducing the dependence on the steering of the bottom moving mechanism 71. This allows the motorized data collector 7 to collect breeding information from structural cages 1 in different directions using a simple moving route. The staff can issue moving, lifting and collecting commands to the motorized data collector 7 through the monitoring terminal 3 via the device gateway 9. Alternatively, the motorized data collector 7 can be installed with a preset travel route for planned movement and lifting and collecting data. The preset travel route can be adjusted and set according to the actual layout position of the structural cages 1, and the lifting height can be adjusted and set according to the actual layout position of the breeding cages 2 on the structural cages 1.

[0036] Furthermore, in some embodiments, the track collector 6 and the motorized collector 7 can be used separately or in combination. A ranging radar can be installed on the outer periphery of the lower fuselage 73 of the motorized collector 7 to determine the distance between the motorized collector 7 and the surrounding structural cage 1, thereby reducing the occurrence of collisions during movement.

[0037] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
