Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a device for monitoring feeding and abnormal weight of group-raised pigs and its usage. Background Technology

[0002] Weight change is an important indicator of pig health. Too rapid weight gain may lead to cardiovascular diseases, while too slow weight gain may indicate malabsorption and stunted growth. Sudden fluctuations in weight may be a signal of stress or disease, such as environmental changes or disease infection. Maintaining normal weight change in pigs is crucial for maintaining their overall health and production performance.

[0003] With the development of modern animal husbandry, the demand for automation and intelligent management of pigs is increasing. In traditional pig farming, feeding, weight monitoring, and pig monitoring rely heavily on manual operation, which is not only inefficient and prone to errors, but also labor-intensive and makes it difficult to accurately monitor changes in pig weight and health status. With the continuous advancement of animal husbandry technology, it is particularly important to develop a device that can feed pigs independently, monitor pig weight and health status in real time, and has remote monitoring capabilities. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a feeding and weight abnormality monitoring device for group-raised pigs and its usage method, which can effectively solve the problems of high labor intensity, low efficiency and difficulty in accurately monitoring the weight changes and health status of pigs in the prior art.

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

[0006] This invention provides a feeding and weight abnormality monitoring device for group-raised pigs, comprising: a feed mixing module, a self-feeding module, a pig identification and weight abnormality monitoring module, and a remote monitoring and intelligent control module. The feed mixing module includes a feed bin, a mixing bucket, and a water pipe. The feed bin's discharge end is connected to a control valve, the other end of the control valve is connected to a discharge pipe, and the other side of the discharge pipe is connected to the mixing bucket. One side of the mixing bucket is connected to a water pipe, the other end of the water pipe is connected to a valve, and the other end of the valve is connected to a faucet. The mixing bucket is equipped with a stirring device.

[0007] The self-service feeding module includes a feed pipe and several feeding areas. One end of the feed pipe is connected to a mixing tank. Fences are fixedly connected between the several feeding areas. A control door is fixedly connected to the front of the fence.

[0008] The pig identification and abnormal weight monitoring module includes an RFID identification device and a weight sensor. The RFID identification device is fixedly connected to the top of the fence and located on the opposite side of the control gate. The weight sensor is fixedly connected to the bottom surface of the feeding area.

[0009] The remote monitoring and intelligent control module includes a remote monitoring device, intelligent control application software, and a camera. The remote monitoring device is wirelessly connected to a multi-functional controller, the intelligent control application software runs on the remote monitoring device, and the camera is installed on the top of several foraging areas.

[0010] Through the above scheme, the silo level sensor can detect changes in the silo level. Once the silo level falls below the lower limit, the multi-functional controller will issue an alert to the farm manager through the intelligent control application software. Several feeding areas can operate independently, and pigs can feed themselves by pressing the spring switch. The pig's identity information and weight information can be uploaded to the multi-functional controller and then reported to the intelligent control application software. The intelligent control application software can record the daily feed intake, weight and health status of each pig, and at the same time monitor the pig's feeding situation in real time as well as control and monitor the operation of the entire system.

[0011] Furthermore, the feed silo includes a cover, a handle, a multi-function controller, and a silo position sensor. The top of the feed silo is rotatably connected to the cover, and the top of the cover is fixedly connected to the handle. The multi-function controller is fixedly connected to one side of the feed silo, and the silo position sensor is fixedly connected to the interior of the feed silo. The mixing tank includes a lid and a handle. The top of the mixing tank is rotatably connected to the lid, and the top of the lid is fixedly connected to the handle. A tank valve connects the mixing tank to the discharge pipe.

[0012] The above solution facilitates staff in opening and closing feed bins and mixing tanks for replenishment and maintenance. The bin position sensor can provide early warning of insufficient feed, and the tank valve can precisely control feed delivery to avoid waste or spoilage.

[0013] Furthermore, a feeding trough is fixedly connected inside the feeding area, and the feeding trough is connected to a feed pipe, and a spring-loaded switch is fixedly connected at the connection between the feeding trough and the feed pipe.

[0014] With the above solution, pigs can trigger the spring switch to obtain feed on their own, reducing waste. Combined with the design of independent feeding areas, it prevents fighting and ensures uniform feeding.

[0015] The above method allows for real-time monitoring of pigs' feeding status, aiding in the detection of health abnormalities. The video data can also be linked to identity and weight data, facilitating the tracing of the causes of abnormalities.

[0016] A method for using a device for monitoring feeding and abnormal weight in group-raised pigs, the method comprising:

[0017] S01, Equipment Assembly: The equipment assembly is completed by following the steps of assembling the feed bin, mixing tank and water pipe, building the feed pipe and feeding area, installing the weight sensor and RFID identification device, arranging the camera, connecting the multi-functional controller and remote monitoring equipment, and system debugging and operation. All subsequent work can be completed under the control of intelligent control application software.

[0018] S02, Feed mixing: Open the control valve and valve, inject feed and water into the mixing tank, and start the stirring device to complete the feed mixing;

[0019] S03, Feed conveying: Control the valve of the tank so that the mixed feed flows into the feed pipe;

[0020] S04, Pig Identification: Open the control gate to allow pigs to enter the feeding area. Each feeding area has a limited width, and only one pig is allowed to enter each feeding area. The identification information of the feeding pig is identified by an RFID identification device and uploaded to the multi-functional controller. Multiple feeding areas can work simultaneously.

[0021] S05, Feeding and Weight Monitoring: The weight sensor detects the weight of the pigs and uploads the data to the multi-functional controller, which then uploads it to the remote monitoring equipment wirelessly. The pigs feed themselves through the spring-loaded switch, and the camera can monitor the feeding status of the pigs in the entire feeding area in real time.

[0022] S06, Data Reporting and Analysis: The multi-functional controller has functions such as display, wireless transmission, and control equipment. The remote monitoring equipment receives the data uploaded by the multi-functional controller and hands it over to the intelligent control application software for processing. The intelligent control application software sends control commands to the multi-functional controller through the remote monitoring equipment. The intelligent control application software can monitor the pigs' feeding status in real time and control and monitor the operation of the entire system.

[0023] S07, Abnormal Warning: The intelligent control application software analyzes the weight changes of pigs over multiple days. The time and frequency of feeding can be tracked and analyzed. The intelligent control application software will alert farm managers to any abnormal pigs.
