There are automatic feeders, intelligent water dispensers, basic environment monitors and other products on the market, which have initially realized the automation of some links in the pet feeding process. Among them, the pet cage as the core feeding equipment, although some products have introduced simple functions such as timed feeding or remote control, but the overall still mainly adopts traditional structure, and each functional module is independently operated, lacking unified collaborative management mechanism.

[0004] However, the existing technology still has many defects: in terms of health control, most pet cages rely on manual cleaning, lack scientific sewage structure and self-cleaning mechanism, and are easy to accumulate bacteria; in terms of feeding management, individual differences of pets are ignored, personalized nutrition supply is difficult to achieve, and there is lack of food intake monitoring and abnormal early warning; the environmental perception ability is weak, and it is impossible to effectively respond to abnormal environment such as high temperature and humidity; the health monitoring and behavior recognition function is limited to basic data collection, and cannot form a management closed loop with the cage hardware; the system integration is low, each module is independently operated, lacking unified main control system and cross-module data sharing mechanism, and remote control only stays at the level of simple operation, which is difficult to meet the intelligent management needs in complex scenarios.

[0039] EMBODIMENT

[0040] As shown in Figure 1 and Figure 2 , the present embodiment provides a multifunctional pet cage system, which comprises a pet cage frame 1 and a central control module. In the present embodiment, the pet cage frame 1 is made of stainless steel material, specifically made of 304 stainless steel cold-rolled square tube, and its yield strength σ sFor 205MPa, and has excellent corrosion resistance, and the surface is sandblasted and coated with 60pm thick electrophoretic protective coating, taking into account the structural strength and surface beauty, it should be pointed out that the material of the pet cage frame 1 includes but is not limited to stainless steel, other materials can be selected according to actual needs, at the same time, the shape and size of the pet cage frame 1 are not limited, its structure can be flexibly adjusted according to the type, size and use scene of the pet, and the stability of each connecting part of the frame needs to be ensured, the overall carrying capacity is enhanced through reasonable distribution and connection of the rod, and deformation or damage is not easy to occur under the condition of pet activity, collision, etc., in order to meet the multiple needs of pet activity space, placement environment adaptability and structural stability. The bottom four corners of the pet cage frame 1 are provided with movable wheels 6, which are fixedly connected with the bottom of the pet cage frame 1 through bolts. The bottom of the pet cage frame 1 is provided with a feces treatment module, the inner side is provided with an intelligent feeding module, the top is provided with an environment monitoring and alarm module 10, the side entrance is provided with a remote control door lock 2, and an intelligent pet collar is provided.

[0041] As shown in Figure 4 The feces treatment module includes circular pipes arranged transversely, an inverted pyramid type base plate 4, a sewage pump 5, a high-pressure water gun 9 and a water storage tank 16. In this embodiment, the material of the circular pipe includes but is not limited to stainless steel, and the circular pipe is fixed to the inner side of the bottom of the pet cage frame 1 by welding, and a plurality of circular pipes are arranged to form a slatted floor, and the pet feces can freely fall into the collection cavity of the inverted pyramid type base plate 4 below. The top opening size of the structure is 910mmx600mm, the bottom opening is 32cm, the inner wall inclination is 20°, which can effectively collect the excrement. The inverted pyramid type base plate 4 is located directly below the circular pipe, and the top edge thereof is welded and fixed to the bottom edge of the pet cage frame 1. The bottom of the inverted pyramid type base plate 4 is connected with the water inlet end of the sewage pump 5. The high-pressure water gun 9 is fixed to the inner side of the pet cage frame 1 through a support, and is connected with the water storage tank 16 through a water pipe 8. A timing water switch 7 is arranged on the water pipe 8, and the water outlet 15 of the high-pressure water gun 9 is arranged corresponding to the inner side of the inverted pyramid type base plate 4. The water storage tank 16 is connected with an external water source through a water inlet 17, and forms a cleaning waterway with the sewage pump 5 through a water outlet 15. After water storage, the feces can be softened and soaked for 20-30 minutes, and then the brushless DC 24V centrifugal pump is used to complete the suction and discharge, so as to ensure that the feces is quickly transferred and isolated from the pet's foot.

[0042] And, the system sets the timing water inlet device to pre-accumulate water in the low activity period at night, and the cleaning process is triggered by the pressure / odor composite sensor after the pet defecates, and the visual interface of the user APP is used to realize the defecation state prompting and maintenance reminding. Meanwhile, when the pet excrement falls into the inverted pyramid type bottom plate 4 through the circular pipe, the high-pressure water gun 9 is used to clean the possible residual dirt in the inverted pyramid type bottom plate 4 after the sewage pump 5 completes the pumping cleaning; when there is still residual dirt after the pumping device is cleaned, the residual dirt can be flushed to the bottom of the inverted pyramid type bottom plate 4 by manually triggering the high-pressure water gun 9 to spray water, and then the residual dirt is discharged out of the system by the sewage pump 5, so as to ensure that the cage environment is clean and has no dead angle.

[0043] As shown in Figure 3 The intelligent feeding module includes a feeding mechanism 3, a grain storage box 11, a shared display screen 12, an eating area 13, a drinking water area 14, a 3D printing distribution tray, a driving motor and a weighing sensor. The grain storage box 11 is fixed to the inner side of the pet cage frame 1, and the bottom discharge port thereof is correspondingly arranged with the 3D printing distribution tray below. The 3D printing distribution tray is rigidly connected with the output shaft of the driving motor through a coupling, and the driving motor is fixed to the bottom of the grain storage box 11 by a bolt connection mode through a support. The eating area 13 is located directly below the 3D printing distribution tray, and the weighing sensor is embedded at the bottom thereof, and the weighing sensor is electrically connected with the central control module.

[0044] The shared display screen 12 is embedded in the position corresponding to the eating area 13 on the inner side of the pet cage frame 1, and is connected between the weighing sensor and the grain storage box 11, and is used to display the remaining food amount in the grain storage box 11 and the real-time eating data of the eating area 13. The drinking water area 14 is arranged adjacent to the eating area 13, and is connected with a water storage tank 16 through a pipeline, and an electromagnetic valve is arranged on the pipeline, and the electromagnetic valve is electrically connected with the central control module to control the water supply frequency. The feeding mechanism 3 integrates the control unit of the grain storage box 11, the 3D printing distribution tray and the driving motor, and is electrically connected with the central control module to receive the control instruction to execute the feeding action. When the central control module issues the feeding instruction, the driving motor drives the 3D printing distribution tray to rotate, and the food in the grain storage box 11 is distributed to the eating area 13 according to the preset amount, the weighing sensor monitors the food consumption in real time, and feeds back the data to the central control module. The feeding instruction is generated in real time by comprehensively considering the activity level, the past eating record and the environmental data fed back by the collar, and when the pet state is low activity or the current environmental temperature exceeds 33°C, the system can automatically delay or adjust the feeding period.

[0045] The environmental monitoring and alarm module 10 comprises a temperature and humidity sensor, an audible and visual alarm, and a set-top box. The temperature and humidity sensor is installed on the top beam of the pet cage frame 1 by a buckle, the set-top box is fixed on the upper part of the outer side of the pet cage frame 1 by a screw, and the audible and visual alarm is integrated in the set-top box. The temperature and humidity sensor and the audible and visual alarm are electrically connected with the central control module, the temperature and humidity sensor is connected with the common display screen 12 in the intelligent feeding module, for collecting and displaying the environmental temperature and humidity data, and the audible and visual alarm is used for issuing a warning in an abnormal condition. When the environmental temperature and humidity exceeds the preset range, the system will automatically trigger the audible and visual alarm, and send alarm information to the user terminal through the Internet of Things communication module. Specifically, the temperature and humidity sensor adopts an industrial level, and the sampling period is 5 minutes; at the same time, the system is provided with an abnormal threshold judgment mechanism, such as temperature > 35℃ or < 5℃, humidity > 80% or < 30%, when the environment is abnormal, the system automatically pushes the alarm through the Internet of Things, and adjusts the sewage discharge and feeding operation logic to adapt to the physiological state of the pet and the environmental comfort.

[0046] As shown in Figure 6 The remote control door lock 2 comprises a stepping motor 21, a connecting rod 22, a rotating buckle 23, and a fixed plate 24. The stepping motor 21 is fixed on the shell of the remote control door lock 2, and the shell of the remote control door lock 2 is fixed on the side of the pet cage frame 1 by welding. One end of the connecting rod 22 is hinged to the output end of the stepping motor 21, and the other end is hinged to the rotating buckle 23. The fixed plate 24 is fixedly connected with the side of the pet cage frame 1, and the rotating buckle 23 cooperates with the fixed plate 24 to realize locking or unlocking. Specifically, the stepping motor 21 drives the connecting rod 22 to swing and drive the rotating buckle 23 and the fixed plate 24 to complete the opening and closing action, which has good fatigue durability and remote control capability. The linkage between the remote control door lock 2 and the intelligent feeding module is realized through the cooperative scheduling of the central control module: when the pet owner remotely initiates the instruction to lock the pet in the cage, the central control module first triggers the intelligent feeding module to start, and the 3D printing distribution disc at the bottom of the grain storage box 11 rotates under the drive of the motor, and feeds food to the feeding area 13, and the drinking water area 14 cooperates to move, and the food attracts the pet outside the cage to return; in this process, the remote control door lock 2 remains unlocked until the positioning information of the intelligent pet collar and the related detection in the cage confirm that the pet has entered the cage, and then the central control module drives the stepping motor 21 of the remote control door lock 2 to complete the locking action through the cooperation of the connecting rod 22 and the rotating buckle 23; after the remote control door lock 2 is locked, the intelligent feeding module stops the feeding action; if the pet does not return within the set time, the intelligent feeding module terminates the guidance, and the remote control door lock 2 remains unlocked. A physical emergency button is also provided at the shell of the remote control door lock 2, which is used for manual unlocking in an emergency. When the central control module receives the unlocking instruction, the stepping motor 21 drives the connecting rod 22 to move, drives the rotating buckle 23 to rotate, and separates the rotating buckle 23 from the fixed plate 24, to realize the unlocking function of the remote control door lock 2.

[0047] As Figure 5 shown, the smart pet collar is provided with a tightness control mechanism 18, and the surface of the smart pet collar is embedded with a display screen 19 and operation buttons 20. The inside of the smart pet collar is integrated with a GPS positioning module, an accelerometer, a gyroscope, a heart rate sensor and a body temperature sensor, each sensor is electrically connected with an AI behavior decoding engine in the smart pet collar, and the smart pet collar is wirelessly connected with an Internet of Things communication module through a BLE5.0 / Wi-Fi6 dual-mode communication unit. The AI behavior decoding engine of the smart pet collar adopts a 3D-CNN and Bi-LSTM hybrid model, the 3D-CNN is responsible for deconstructing continuous motion frames and accurately identifying micro-difference actions, such as distinguishing between a golden dog rolling and a seizure, and the recognition accuracy reaches 95.3%; the Bi-LSTM further analyzes the behavior logic chain, such as acceleration→sudden stop→lament, which indicates that it may be injured, and realizes high-accuracy risk prediction. After the model is deployed locally, the size is less than 1MB, the inference delay is less than 100ms, and the reaction speed is milliseconds.

[0048] Specifically, when it is detected that the pet struggles acceleration exceeds the preset threshold, such as acceleration > 4g and lasts for a preset duration > 5s, abnormal stillness exceeds the preset duration 30min or body temperature exceeds the preset threshold 39.5℃, the central control module receives the signal transmitted by the smart pet collar, drives the stepper motor 21 of the remote control door lock 2 to unlock, triggers the sound and light alarm of the environment monitoring and alarm module 10, and pushes the alarm information containing the GPS positioning information of the pet and the heart rate and body temperature data to the user terminal through the Internet of Things communication module. The smart pet collar can monitor the physiological state and behavior pattern of the pet in real time, analyze the data through the AI behavior decoding engine, identify abnormal conditions and alarm in time, and protect the safety of the pet. In this embodiment, the remote unlocking instruction is sent by the main control chip (STM32F4, 168MHz) through the MQTT protocol, and the standby mechanical release device is activated, so that the pet can quickly escape; at the same time, the system combines heart rate variability (HRV) and motion trend to evaluate the hunger level (the error is controlled within ±5%), and dynamically adjusts the feeding strategy of the grain storage box 11, such as reducing the supply of main food by 10% on high temperature days and increasing the water supply frequency, to ensure accurate matching of physiological needs.

[0049] The central control module includes a main control chip and a real-time operating system, and is connected with the Internet of Things communication module through a communication protocol. The central control module is electrically connected with the excrement treatment module, the intelligent feeding module, the environment monitoring and alarm module 10, and the remote control door lock 2, so as to realize the control and data interaction of each module. The central control module can dynamically adjust the feeding plan of the intelligent feeding module according to the pet motion data and the environment temperature and humidity data; when the temperature in the environment temperature and humidity data exceeds the preset threshold value, the central control module controls the intelligent feeding module to reduce the amount of main food feeding and increase the water supply frequency of the water supply area 14. The central control module realizes encrypted data transmission with the intelligent pet collar and the user terminal through the Internet of Things communication module, and the central control module is built-in with a power supply, supports power-off endurance for a preset time, and has a network disconnection automatic reconnection mechanism.

[0050] Specifically, as shown in Figure 8 The central control module is mainly based on the main control chip, each functional module is connected with the specified pin of the main control chip through the Dupont line, and the data interaction and accurate control are completed by relying on the adapted communication protocol. The core connection and control logic are completely matched with the collaborative operation requirements of the system functional modules.

[0051] The connection and control logic of the central control module and the environment monitoring and alarm module 10 are as follows: the A0 pin of the main control chip is connected with the DHT11 temperature and humidity sensor through the Dupont line, and the temperature and humidity data in the pet cage are collected in real time by using the single bus communication protocol; after these data are transmitted to the main control chip, on the one hand, the environment data are displayed locally by being pushed to the common display screen 12 of the intelligent feeding module through the communication protocol, and on the other hand, the data are compared with the preset environment threshold (such as temperature > 35℃ or < 5℃, humidity > 80% or < 30%), when the detected data exceed the threshold, the main control chip sends a trigger signal to the audible and visual alarm integrated in the set-top box, and controls the LED lamp connected with the B8 pin to flash, forming a dual warning mechanism of audible and visual alarm + light prompt, to ensure that the abnormal environment state is sensed in time. In addition, when the main control chip receives an abnormal signal (such as pet body temperature exceeding 39.5℃ or abnormal stillness time exceeding 30min) from the intelligent pet collar, the response of the environment monitoring and alarm module 10 is immediately strengthened, and the audible and visual alarm is driven to work continuously until the abnormal state is removed or the user confirms.

[0052] In connection with the intelligent feeding module and control, the A11 and A12 pins of the main control chip are connected with the HX711 weighing sensor module through the Dupont line, the real-time weight data at the bottom of the feeding area 13 is transmitted by differential signal, so as to judge the remaining amount of food in the feeding area 13; when it is detected that the remaining amount is lower than the preset threshold, the main control chip will send a PWM control signal to the motor drive board connected to the B12-B15 pins, drive the motor to rotate the 3D printing distribution disc, and realize quantitative feeding according to the preset rotation angle (such as rotating 180° corresponding to feeding 20g of food), the weighing sensor will continuously feed back the weight change during the feeding process, and after the target feeding amount is reached, the main control chip immediately sends a stop signal to control the distribution disc to stop rotating. At the same time, the B10 and B11 pins of the main control chip are connected with the display screen 19 through the Dupont line, the display screen 19 is linked with the common display screen 12 of the intelligent feeding module, and the remaining food amount in the grain storage box 11 and the real-time feeding data (such as single feeding amount, feeding time) of the feeding area 13 are refreshed in real time by using the I2C communication protocol, and the user can also input the customized feeding instructions (such as timing feeding time, single feeding amount) through the common display screen 12, the instructions are transmitted to the main control chip through the display screen 19, and the main control chip stores and executes the corresponding control logic. In addition, the A1 pin of the main control chip is connected with the local button through the Dupont line, when the user needs emergency feeding on site, pressing the button can trigger an interrupt signal, and after the main control chip receives the signal, it will skip the normal timing logic and directly drive the motor to execute the preset emergency feeding amount, meeting the temporary feeding demand.

[0053] For the excrement treatment module, the main control chip realizes control of different components through the C13 and C15 pins: the C13 pin is connected with the relay module through the Dupont line, the relay output end is connected with the power supply of the sewage pump 5 in series, when the main control chip detects the excrement accumulation signal (or reaches the preset cleaning time), a high level is output to trigger the relay to attract, and the sewage pump 5 is started to pump the excrement; the C15 pin is connected with the two-way delay relay module, one way controls the timing water switch 7 of the high-pressure water gun 9, and the other way controls the water inlet electromagnetic valve of the water storage tank 16, forming a cooperative cleaning process: before the sewage pump 5 is started, the main control chip will control the water inlet electromagnetic valve to open, and water is injected into the inverted pyramid type chassis 4 to soften the excrement, after the sewage pump 5 is operated, the high-pressure water gun 9 is triggered to spray water, and the chassis is cleaned again to avoid residue. At the same time, the main control chip will combine the temperature data collected by the DHT11 temperature and humidity sensor, when it is detected that the temperature in the cage is greater than 35℃, the cleaning interval will be automatically shortened (such as from the normal 2h / time to 1h / time), the cleaning process is triggered in advance through the C13 and C15 pins, and the risk of bacteria breeding in high temperature environment is reduced.

[0054] In terms of connection and control of the remote control door lock 2 and the smart pet collar, the B12-B15 pins of the main control chip are connected to the stepping motor 21 drive board of the remote control door lock 2 through DuPont wires, and pulse signals are used to control the rotation angle of the stepping motor 21 to realize the unlocking and locking of the door lock. When receiving the user's remote unlocking instruction or the abnormal signal transmitted by the smart pet collar (such as pet struggle acceleration > 4g and lasting more than 5s), the main control chip will send a pulse signal of 90° reverse rotation to drive the stepping motor 21 to drive the connecting rod 22 and the rotating buckle 23 to act, completing the unlocking of the door lock. When the positioning information of the smart pet collar confirms that the pet has entered the cage, a pulse signal of 90° forward rotation is sent to realize the locking of the door lock. At the same time, the A2 and A3 pins of the main control chip are connected to the ESP8266 Wi-Fi module through DuPont wires, and the A7 and A8 pins are connected to the 4G module. The Wi-Fi module is used to establish a wireless connection with the BLE5.0 / Wi-Fi6 dual-mode communication unit of the smart pet collar, and real-time receive the GPS positioning, heart rate, body temperature and behavior data (such as motion data collected by the accelerometer and gyroscope) transmitted by the collar. When the AI behavior decoding engine of the central control module identifies abnormal data, the main control chip will push alarm information containing pet GPS positioning information, heart rate and body temperature data to the user terminal through the 4G module, forming a closed loop of data acquisition, abnormal identification and remote alarm.

[0055] In addition, the main control chip also has debugging and power supply guarantee functions: the A9 and A10 pins are connected to the CH340 serial module through DuPont wires, supporting USB-to-serial communication. This connection can be used for debugging the main control program (such as troubleshooting software code errors and optimizing module control logic), and also can realize program burning and parameter configuration (such as adjusting temperature and humidity abnormal threshold and feeding amount standard). The 5V and 3.3V pins provide adaptive power supply for each module through DuPont wires (such as the HX711 weighing sensor module connected to 3.3V and the stepping motor 21 drive board connected to 5V). At the same time, the system is connected to the battery power supply interface (such as a 3.7V lithium battery) through the VB pin. The original power supply provided by the VB pin is converted to 3.3V and 5V by a voltage stabilizing circuit (such as an LDO) and supplied to the chip and peripherals. The GND pin is common to all modules to ensure stable signal transmission without interference. The central control module has a built-in backup power supply. When the main control chip detects external power failure, it will automatically switch to backup power supply, supporting 72h endurance, while maintaining the power supply of key components such as A2 / A3 Wi-Fi module, A7 / A8 4G module and C13 relay, ensuring that abnormal signal transmission and emergency control functions are not affected by power failure.

[0056] Meanwhile, in this embodiment, the data collected by the smart pet collar is synchronized to the user's mobile phone APP after AI processing in the cloud, building a health visualization panel, including 72-hour heart rate curve, activity heat map, behavior segment classification and comprehensive score. Users will receive smart prompts, such as low daily exercise, suggesting an additional 15 minutes of outdoor activity, and can also view real-time positioning and security fence status. In addition, veterinarians can call professional reports generated by the collar through the authorized platform, such as HRV curve, body temperature change graph, environmental humidity trend, etc., to assist in diagnosis and improve efficiency by more than 50%. The control and communication module uses an STM32F4 main control chip and Wi-Fi and 4G modules to realize local and wide-area Internet of Things communication, with a built-in 3000mAh high-density lithium battery supporting 72 hours of power failure endurance, with automatic reconnection and communication exception repair mechanism. It should be noted that the software of this multifunctional smart pet cage system runs on the FreeRTOS v10.4.1 real-time operating system, with a 1ms periodic task scheduling to control the response of each module, and all key data is encrypted and uploaded to the Ali Cloud Internet of Things platform through the MQTT protocol; the user interface is developed based on the LVGL 8.2 graphics library, supporting touch interaction, real-time display of pet physiological state, environmental information, feeding plan, and remote control door lock2 control, and other core information.

[0057] The multifunctional pet cage system realizes intelligent management of pets through the cooperative work of each module. The central control module, as the core of the system, receives pet physiological data and behavior data from the smart pet collar, combines environmental data collected by the environmental monitoring and alarm module 10, and performs comprehensive analysis through the AI behavior decoding engine to make appropriate decisions. For example, when the pet's activity level increases, the system will automatically adjust the feeding amount; when the environmental temperature rises, the system will reduce food supply and increase water frequency; when an abnormal state of the pet is detected, the system will automatically unlock the remote control door lock2 and issue an alarm. The feces processing module keeps the cage environment clean and improves the quality of life of pets. The whole system realizes intelligent, automated and personalized management of the pet feeding process, greatly reducing the burden of pet owners, while improving the quality of life and safety of pets.

[0058] Reference Figure 7The working principle of the multifunctional intelligent pet cage system is that the intelligent pet collar is used as the main data collection end, the central control module is used as the decision center, each functional module is linked through the Internet of Things communication module, and an intelligent management closed loop of sensing, decision making, execution and feedback is constructed. The intelligent pet collar integrates multiple sensors, and real-time physiological and motion data of the pet are collected. After analysis by an AI behavior decoding engine, if the pet is identified to have violent struggle, abnormal stillness or body temperature rising, etc., the remote control door lock 2 is unlocked within 0.5 seconds, sound and light alarms are triggered, and an alarm containing pet positioning and physiological data is pushed to the user terminal. The feces treatment module combines the feces detection unit and temperature and humidity data. When the ambient temperature is greater than 35 DEG C, the cleaning frequency is increased, and the inverted pyramid soaking, centrifugal pump sewage discharge and high-pressure water gun 9 secondary cleaning process are started in turn to realize efficient decontamination.

[0059] The intelligent feeding module combines the collar motion amount and environmental temperature data. When the temperature is greater than 33 DEG C, the main food feeding amount is reduced by 10% and the drinking water frequency is increased. The 3D printing distribution disc is driven by the motor to feed the food, the weighing sensor verifies the feeding accuracy, and the feeding data is updated synchronously. The temperature and humidity sensor of the environmental monitoring and alarm module 10 collects data. When the temperature and humidity are greater than 35 DEG C or less than 5 DEG C or the humidity is greater than 80%, sound and light alarms and APP push are triggered directly. All module operation data are uploaded to the cloud health database, the health weekly report is generated and pushed to the veterinarian platform, the whole-link intelligent management from real-time sensing to long-term health tracking is realized, and the pet feeding is more intelligent, efficient and scientific.

[0060] Therefore, by using the above multifunctional intelligent pet cage system, through the integration of mechanical structure optimization, fluid self-cleaning system, personalized feeding control, multi-modal environment sensing, Internet of Things communication and intelligent control strategy, multi-module collaborative operation, data closed-loop management and remote linkage response are realized, and the technical problems of the existing pet cage in feces treatment, intelligent feeding, environmental regulation, health monitoring and system integration are solved efficiently.
