Description

Technical Field

[0001] This utility model belongs to the field of livestock and poultry breeding technology, specifically relating to a sow farrowing early warning system. Background Technology

[0002] Farrowing in sows often occurs at night, and its notable characteristics include: 12 to 24 hours before farrowing, the sow's body temperature may drop from the normal 38.5-39.5℃ to 37.5-38℃; several hours before farrowing, the sow may exhibit increased respiratory rate (exceeding 40 breaths / minute), accompanied by grunting, frequent turning over, and lying down. In large-scale farms, due to the large number of sows, it is difficult for staff to continuously observe each sow. Nighttime duty not only further increases the manpower burden but also leaves blind spots in supervision. Furthermore, sows giving birth alone without supervision are prone to crushing piglets and may also face risks such as dystocia, endangering the health of both mother and offspring and causing economic losses.

[0003] Therefore, there is an urgent need for a farrowing early warning system that can monitor the physiological and behavioral indicators of sows in real time. By collecting and analyzing key parameters such as body temperature, sound, and activity, the system can predict the start of farrowing in a timely manner, thereby effectively solving the above problems.

Detailed Implementation

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.

[0017] Please see Figures 1 to 4 This embodiment provides a sow farrowing early warning system, mainly including a sow lying-up information acquisition device, a sound acquisition device 2, a temperature acquisition device 3, and a data processing center. The sow lying-up information acquisition device is installed on the ground of the sow nursery pen 1. The sound acquisition device 2 and the temperature acquisition device 3 are respectively fixedly installed on the upper side of the fence of the nursery pen 1, facing the sow's torso area. All acquisition devices are connected to the data processing center via cables 4. First, an insulating rubber mat 5 is laid on the clean and dry nursery pen 1 floor. The mat is the same size as the pen floor and has a pre-set crisscrossing grid-like channel about 1cm deep and 1.5cm wide inside. Then, multiple pressure sensing strips 6 are embedded one by one into the corresponding grid-like channel. The two leads of each pressure sensing strip 6 pass through the outlet hole at the end of the channel. Finally, the leads of all pressure sensing strips 6 are connected to the input terminal of a multiplexer installed in a waterproof electrical box 8 outside the pen via cables 7. The output of the multiplexer is connected to the data processing center located in the monitoring room of the farm via an RS-485 bus.

[0018] The pressure sensing band 6 includes: The flexible insulating outer layer 9 is made of high-strength PVC material and sealed by hot pressing process; Upper conductive electrode 10 and lower conductive electrode 11: Both are made of conductive silicone tape with a thickness of 0.5mm, and are arranged in parallel in the sealed cavity formed by the flexible insulating outer layer 9; one end of the upper conductive electrode 10 and the lower conductive electrode 11 extends out of the outer layer by about 10cm respectively to form the first lead 12 and the second lead 13, and their ends are crimped with metal terminals to facilitate quick connection with the cable 7.

[0019] Multiple insulating isolation points 14 are formed within a sealed cavity. These cylindrical rubber protrusions, each 1mm high and 2mm in diameter, are fixed to the lower conductive electrode 11 at 5cm intervals via heat fusion to support the upper conductive electrode 10. When the pressure sensing band 6 is subjected to external pressure, the upper conductive electrode 10 and the lower conductive electrode 11 can overcome the spacing of the insulating isolation points 14 at the pressure point and make contact, thereby closing the circuit between the first lead 12 and the second lead 13. The upper conductive electrode 10 and the lower conductive electrode 11 are arranged parallel to each other within the sealed cavity formed by the flexible insulating outer layer 9. One end of the upper conductive electrode 10 and one end of the lower conductive electrode 11 extend out of the flexible insulating outer layer 9, forming a first lead 12 and a second lead 13 for connection with the cable 7. A plurality of insulating isolation points 14 are spaced apart between the upper conductive electrode 10 and the lower conductive electrode 11 to keep them separated in the absence of external force. When the pressure sensing strip 6 is subjected to external pressure, the upper conductive electrode 10 and the lower conductive electrode 11 can overcome the spacing of the insulating isolation points 14 at the pressure point and make contact, thereby closing the circuit between the first lead 12 and the second lead 13. During on-site installation, the operator only needs to directly plug the terminal block at the end of the pressure sensing strip 6 lead into the connector at the end of the cable 7, without welding, greatly improving installation efficiency and ease of later maintenance.

[0020] Cable trays 15 are provided on the adjacent sides of the rubber pad 5 to accommodate cables 7 and converge them to a multiplexer. Alternatively, the upper conductive electrode 10 and lower conductive electrode 11 can also be made of conductive rubber. The insulating isolation points 14 can also be small protrusions molded from ABS plastic and bonded between the electrodes with food-grade adhesive. The sound acquisition device 2 uses a waterproof microphone with an IP67 protection rating, which is fixed to the fence approximately 1 meter above the ground using a universal bracket. The temperature acquisition device 3 uses infrared temperature sensors; four infrared temperature sensors are positioned at the four corners of the enclosure 1 to avoid blind spots in temperature data acquisition.

[0021] Hardware configuration and logical judgment functions of the data processing center The data processing center is an industrial control computer (IPC) installed in the monitoring room of the farm. As the core control and judgment unit of the system, it is equipped with multiple serial port cards and digital I / O cards.

[0022] The data processing center is configured to perform the following logical judgment and collaborative control functions: The lying-up / standing-up state logic judgment unit: The data processing center cyclically collects the on / off state signals of each pressure sensor band 6 through a multiplexer. It is configured to: determine the sow's "lying down" and "standing up" states according to the preset "effective area" logic (i.e., when multiple adjacent sensor points in a certain area are triggered at the same time), and automatically count the number of times the sow lies down / stands up within a unit of time (e.g., 1 hour).

[0023] Audio signal logic judgment unit: The data processing center receives the analog audio signal collected by the microphone and compares it with a pre-stored standard level threshold through its internally integrated comparator circuit. It is configured to determine a valid characteristic tone when the intensity and frequency of the audio signal continuously exceed the preset threshold.

[0024] Body temperature trend logic judgment unit: The data processing center receives the voltage signal uploaded by the infrared temperature sensor (which is linearly correlated with the temperature value). It is configured to continuously record body temperature data and compare the current value with the historical average value of the previous period in real time through its internal comparator. When a continuous decrease in body temperature value is detected and it falls below a preset threshold, a body temperature decrease flag is triggered.

[0025] Integrated Decision Logic Judgment Unit: The data processing center is configured to receive the output signals of the above three judgment units (excessive frequency of getting up and lying down signal, characteristic sound trigger signal, and body temperature drop indicator). Internally, it implements a decision logic through a simple OR / AND gate circuit or programmable logic device (such as CPLD): when two or three of the signals are received, a high-level labor warning trigger signal is generated.

[0026] The data processing center is connected to an audible and visual alarm. The digital I / O output port of the data processing center is configured such that when its integrated decision logic judgment unit outputs a high-level labor warning trigger signal, a high level is immediately written to the digital I / O port, directly driving the external audible and visual alarm circuit to conduct, thereby activating the audible and visual alarm.

[0027] All sensors and the data processing center transmit signals via a wired network consisting of shielded twisted-pair cables, armored cables, and industrial Ethernet to ensure the system's anti-interference capability and reliability.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
