Description

Technical Field

[0001] The present invention relates to the technical field of intelligent breeding, and particularly relates to a feed intake monitoring device and system based on bovine mandibular movement pressure sensing. Background Art

[0002] Feed intake is a direct factor reflecting the nutritional status of livestock. Monitoring the feed intake of cattle can not only help farmers optimize feeding plans and reduce feed waste, but also promptly detect and handle diseases to ensure the health of cattle. Currently, the methods for measuring feed intake at home and abroad mainly include two categories: plant-based and animal-based. The plant-based method is mainly applied to grazing cattle, and the feed intake is determined by measuring the change in the biomass of grassland plants before and after grazing, that is, the subtraction method. The animal-based methods mainly include the grazing behavior method, the relationship method between digestibility and fecal output, the alkane method, the near-infrared method, and the weighing trough method, etc.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figures 1-7 The invention describes a feed intake monitoring device and system based on bovine mandibular movement pressure sensing.

[0026] Figure 1 is a structural schematic diagram of a feed intake monitoring device based on cattle mandibular movement pressure sensing provided by the present invention, such as Figure 1 As shown, the device includes: a main control module 102, a liquid bag 104 and a strap 106. The main control module 102 includes a single chip microcomputer 1022, a hydraulic pressure sensor 1024 and a communication module 1026. Among them: The strap 106 is used to be worn on the head of the cow.

[0027] The liquid bag 104 is attached to the strap, and the lower surface of the liquid bag is attached to the upper part of the nose restraint after wearing.

[0028] The main control module 102 is disposed on the liquid capsule.

[0029] The hydraulic sensor 1024 is used to collect the pressure data of the fluid sac when the cow's mandible moves.

[0030] The microcontroller 1022 is used to transmit the pressure data to the application platform through the communication module 1026. The application platform is used to analyze and process the pressure data and output the individual feed intake of the cattle.

[0031] Among them, the strap is used to attach the core components of the device and is worn on the head of the cattle. As Figure 2 shown, the strap includes a neck band and a nose band. The neck band and the nose band are respectively used to surround and fix on the neck and nose of the cattle. The neck band and the nose band are adjustable in tightness and can be fixed at the end with a buckle. The strap is designed to be adjustable in tightness to adapt to cattle of different body sizes. The strap can be added with an anti-slip design to prevent the device from sliding or falling off. The strap can use flexible materials to ensure firmness and not harm the cattle. The liquid sac, the main control module, the main control module housing and the lithium battery are attached to the strap. The wearing effect is as Figure 3 shown.

[0032] The liquid sac is formed by bonding two layers up and down. The upper layer of the liquid sac is attached to the strap, attached to the strap and does not bear the tensile force of the strap. The lower surface can be attached to the upper part of the cattle nose bridle after wearing. The material of the liquid sac can be selected as a flexible material with anti-tensile, wear-resistant and waterproof properties to reduce the risk of wear and liquid leakage. For example, TPU (Thermoplastic Polyurethane) material can be selected.

[0033] The hydraulic sensor is designed with an IIC (Inter-Integrated Circuit) communication circuit connected to the microcontroller. The measuring range is 1000 - 1500 mBar, the sensor accuracy is 100 - 200 mBar, and the sampling frequency is 2 - 5 Hz. The pressure data acquisition sets a trigger threshold to reduce the burden of data volume. When the pressure data reaches the threshold, the pressure data is started to be collected. For example, the threshold can be 800 mbar to reduce invalid data acquisition.

[0034] The communication module can adopt a 4G CAT1 module. The communication module is powered by the microcontroller. The communication module can be designed with an antenna interface to optimize the communication quality. The communication module can integrate a USB interface and a USIM card slot, and a Micro Sim card can be inserted.

[0035] There is a main control module housing outside the main control module. The main control module housing adopts an impact-resistant housing to protect the internal circuit and sensors. It uses weather-resistant materials to adapt to the outdoor environment. The waterproof level is IP65 / IP67, effectively preventing damage caused by rain and cattle licking.

[0036] The above-mentioned feed intake monitoring device based on bovine mandibular movement pressure sensing is worn on the head of the cow through a strap. The liquid sac is attached to the strap. After wearing, the lower surface of the liquid sac fits against the upper part of the bovine nose rein. The pressure data of the liquid sac during the movement of the bovine mandible is collected by a hydraulic sensor, and then the pressure data is transmitted to the application platform through a single-chip microcomputer via a communication module. The application platform analyzes and processes the pressure data and outputs the individual feed intake of the cow, avoiding the problems of large storage space required for using an image sensor, being easily interfered by noise when using a sound sensor, and being easily interfered by head movement when using an inertial sensor, achieving the effects of reducing the storage space requirement, being free from noise interference, and being free from head movement interference. In addition, by transmitting the pressure data to the application platform for analysis and processing, the problem of cumbersome data usage caused by only local storage of data in the device is avoided, and the efficiency of data processing and analysis is improved. The liquid sac can quickly detect changes in pressure values and the pressure is evenly distributed, and can quickly capture pressure data during the movement of the bovine mandible, ensuring the stable operation of the device while improving the sampling accuracy of the pressure data and providing more accurate data. The liquid sac is attached to the strap and does not bear the tensile force of the strap, avoiding the problem of telescopic fatigue of the liquid sac caused by tensile stress. The present invention is applicable to cows under both housed and grazing conditions. By wearing the feed intake monitoring device based on bovine mandibular movement pressure sensing on the cow, real-time monitoring of the pressure data at the cow's mouth can be achieved, thereby calculating the number of behaviors and the feed intake, helping the breeding personnel evaluate the feed intake and feed utilization rate of the cow and then adjust the feeding plan, assisting in monitoring the health status of the cow, and providing a new technical equipment for scientific and accurate production and feeding.

[0037] In one embodiment, as Figure 4 shown, the liquid sac is formed by bonding an upper layer and a lower layer, and the overall shape is arc-shaped to fit against the upper part of the bovine nose rein. The upper layer is a flat layer, and the lower layer is concave. A liquid medium is filled in the cavity between the upper and lower layers; the connection between the upper and lower layers is connected by a slot bite structure.

[0038] Among them, the slot bite structure can be a C-shaped slot bite structure. Figure 5 The part circled and indicated by the arrow in

[0039] is the C-shaped slot bite structure at the connection between the upper and lower layers of the liquid sac. In the above embodiment, the connection between the upper and lower layers of the liquid sac is connected by a slot bite structure, which is convenient for bonding and avoids the risk of liquid leakage. The overall arc-shaped design that fits against the upper part of the bovine nose rein ensures wearing comfort.

[0040] In one embodiment, the liquid medium is propylene glycol.

[0041] In the above embodiments, the liquid medium filled in the liquid sac is propylene glycol, which is non-toxic, pollution-free, low-cost, and can make the pressure sensing signal hardly affected by high and low temperature environments, and the pressure it bears is stable.

[0042] In one embodiment, a liquid supplement port is provided on the main control module; the liquid supplement port is communicated with the inside of the liquid sac; the liquid supplement port is used to supplement the liquid medium into the liquid sac.

[0043] A sealing screw can be provided on the liquid supplement port, and by unscrewing the sealing screw, liquid can be supplemented through the liquid supplement port.

[0044] In the above embodiments, by providing a liquid supplement port on the main control module, the liquid sac can be replenished with liquid, avoiding the problem of inability to replenish liquid.

[0045] In one embodiment, the feed intake monitoring device based on bovine mandibular movement pressure sensing further includes a lithium battery; the main control module further includes a power supply module.

[0046] The power supply module includes a battery power monitoring chip for power management. An overcharge and over-discharge protection circuit is designed, and a power indicator is designed to check the power status.

[0047] In the above embodiments, using a rechargeable lithium battery for power supply is convenient. The power supply module has a charging interface, and the lithium battery can be charged without removing the battery, reducing the trouble of wearing the device back and forth.

[0048] In one embodiment, the main control module further includes a storage module. The single-chip microcomputer is also used to compress the pressure data to obtain a compressed file; the storage module is used to store the compressed file; the single-chip microcomputer is also used to transmit the stored compressed file to the application platform through the communication module.

[0049] The storage module includes an SD storage driver to ensure sufficient storage space for the data of the target number of days, for example, sufficient storage space for 7 days. An SDMMC interface is designed to connect the single-chip microcomputer and the SD card, providing a file system support (FATFS) for storing the compressed file. The stored compressed file can be transmitted to the application platform through the communication module at every first preset time interval to achieve intermittent transmission.

[0050] In the above embodiments, compressing the pressure data to obtain a compressed file and transmitting the compressed file to the application platform can shorten the data transmission time, improve the transmission efficiency, and reduce the problems of data accumulation and too long transmission time caused by too large data volume. Storing the compressed file in the storage module and then transmitting the stored compressed file can avoid data loss.

[0051] In one embodiment, a switch button is provided on the main control module; the switch button adopts a recessed and hidden design.

[0052] The switch button is used to control the start, stop, and reset of data acquisition of the feed intake monitoring device based on bovine mandibular movement pressure sensing.

[0053] In the above embodiment, the use of a hidden switch design reduces the risk of accidental touching of the switch and makes the appearance more beautiful.

[0054] In one embodiment, the hydraulic sensor triggers the acquisition of pressure data when the pressure reaches the threshold, and the sampling frequency is 2 to 5 Hz; the feed intake monitoring device based on bovine mandibular movement pressure sensing includes a low-power mode and a high-performance mode in the working state; when data acquisition and data transmission are not triggered, the feed intake monitoring device based on bovine mandibular movement pressure sensing is in the low-power mode; when data acquisition and data transmission are triggered, the feed intake monitoring device based on bovine mandibular movement pressure sensing is in the high-performance mode.

[0055] After the device is powered on and the switch is turned on, the device is in the working state, which includes a low-power mode and a high-performance mode in the working state.

[0056] In the above embodiment, the hydraulic sensor triggers the acquisition of pressure data when the pressure reaches the threshold, and the sampling frequency is 2 - 5 Hz, which can reduce the burden of data volume. When data acquisition and data transmission are not triggered, the feed intake monitoring device based on bovine mandibular movement pressure sensing is in the low-power mode; when data acquisition and data transmission are triggered, the feed intake monitoring device based on bovine mandibular movement pressure sensing is in the high-performance mode, which can reduce power consumption.

[0057] In one embodiment, as Figure 6 shown, the feed intake monitoring device (wearable device) based on bovine mandibular movement pressure sensing includes a main control module, a main control module housing, a lithium battery, a liquid sac, and a strap. The main control module includes a single-chip microcomputer (MCU), a hydraulic sensor, a communication module (4G CAT1 module), a power module (lithium battery chip), and a storage module (SD storage chip). The single-chip microcomputer is powered by the lithium battery.

[0060] The application platform 702 is used to analyze and process the pressure data, obtain the individual feed intake of the cattle and output and display it.

The application platform deploys a feed intake calculation model, calls the database data, and calculates the individual feed intake of the cattle every second preset time interval through the feed intake calculation model and outputs and displays it. For example: the second preset time interval can be 1 hour.

[0062] For the above feed intake monitoring system based on bovine mandibular movement pressure sensing, the pressure data of the liquid sac during the movement of the bovine mandible is collected by the feed intake monitoring device based on bovine mandibular movement pressure sensing and transmitted to the application platform. The application platform analyzes and processes the pressure data to obtain the individual feed intake of the cattle and outputs and displays it, avoiding the problems of large storage space required for using an image sensor, being easily interfered by noise when using a sound sensor, and being easily interfered by head movement when using an inertial sensor, achieving the effects of reducing the storage space requirement, being free from noise interference, and being free from head movement interference.
