Description

Technical Field

[0001] The present invention relates to the technical field of pig farms, and in particular to a smart pig farm breeding data collection device and method. Background Art

[0002] Smart pig farm is a modern farming model that uses information technology and automated equipment to improve pig farm management efficiency and production benefits. Smart pig farm uses big data technology to collect and analyze a large amount of farming data, such as pig body temperature, movement status, air temperature, humidity, ammonia concentration, etc. By analyzing this data, it is possible to optimize feeding strategies, improve production efficiency, and even predict disease outbreaks.

[0003] Existing smart pig farms often use infrared cameras to obtain pig body temperature. Although the measurement speed is fast and the surface temperature of multiple pigs can be measured in a short time, it is non-contact measurement and is affected by external factors, resulting in inaccurate measurement. In addition, wind speed and humidity will affect the pig's perceived temperature. Therefore, the pig's body temperature obtained by infrared cameras is incorrect and cannot reflect the pig's perceived temperature, which cannot guarantee the pig's comfort and affects pig breeding. Summary of the invention

[0004] In view of the above problems in the prior art, the present invention provides a smart pig farm breeding data collection device and method, which solves the problem that the existing smart pig farm cannot accurately obtain the pig's body temperature through a single infrared camera.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: On the one hand, a smart pig farm breeding data collection device is provided, including: a track inspection robot, the track inspection robot includes a track arranged above the pig farm and a robot movable on the track; a data collection module, the data collection module includes a communication module fixed on the robot and an infrared camera, a humidity sensor and a wind speed sensor electrically connected to the communication module, and the communication module is communicatively connected to an external control terminal; a temperature collection component, the temperature collection component includes a positioning identification ear tag for locating the position of the pig and identifying the identity of the pig and an ear temperature collector for detecting the temperature of the pig's ear, the positioning identification ear tag is electrically connected to the ear temperature collector and is communicatively connected to the communication module.

[0006] In this solution: Since the internal environment of the ear canal is relatively stable and the temperature fluctuation is small, the ear temperature collector can obtain stable ear temperature data of the pigs. By marking multiple pigs evenly distributed in the pig farm as marked pigs, the number of temperature collection components used is reduced and the cost is reduced. In addition, the accurate ear temperature data of each marked pig can be used to correct the body temperature data of all pigs in the marked pig area. Therefore, this solution obtains the position information of the marked pig by locating and identifying the ear tag, so that the track inspection robot drives the data acquisition module on it to move to the position and obtains all the pig body temperature data, humidity data and wind speed data in the position area. After conversion by the external control terminal, the body temperature of the pigs in each area of ​​the entire pig farm can be accurately obtained, which is convenient for the staff to adjust the environment of the pig farm to improve the comfort of the pigs and is conducive to the healthy growth of the pigs.

[0007] Furthermore, the positioning and identification ear tag includes a main tag and an ear plug set on the pig's auricle. The main tag is provided with an installation cavity inside, and the installation cavity includes an upper cavity and a lower cavity. The upper cavity is provided with a processor and a positioning module electrically connected to the processor, a tag chip, an antenna module and a battery module; the lower cavity is provided with a winding reel, and the winding reel is provided with a power signal line; the bottom of the main tag is provided with an internal hollow connecting column, one end of the connecting column passes through the ear hole on the pig's auricle and is fixedly connected to the ear plug, and the power signal line passes through the middle of the connecting column and the ear plug in turn and is electrically connected to the ear temperature collector. The positioning module and the tag chip are used to obtain the pig's location information and the pig's identity information respectively, and transmit them to the data acquisition module through the antenna module. The power signal line on the cable reel passes through the ear plug from the connecting column and is electrically connected to the ear temperature collector. It not only supplies power to the ear temperature collector and transmits ear temperature data, but also has a certain contraction force. It can retract the ear temperature collector onto the ear plug after it becomes loose, thus preventing the ear temperature collector from falling off and falling directly to the ground due to the pig's activities, and also preventing the pig from accidentally eating it. At the same time, the contraction force of the cable reel also ensures that when the pig moves its ears, the power signal line can adaptively change its length, thus preventing the ear temperature collector from being pulled off by the pig's ears. The power signal line passes directly through the connecting column, thus avoiding routing the line outside the pig's ears.

[0008] Furthermore, an end cover is provided on the upper cavity, and a ring-shaped breathing light is embedded on the end cover, and the breathing light is electrically connected to the processor. The breathing light can reflect the state of the pig through different colors. If the pig's body temperature is too high, the breathing light can be red, and if the pig's body temperature is too high, the breathing light can be green, which is convenient for reminding the breeding staff.

[0009] Further, the ear temperature collector includes an earphone body, which is a truncated cone structure with a hollow interior and openings at both ends, a flexible earplug is sleeved on the conical surface of the earphone body, a temperature sensor is arranged on the small-diameter end surface of the earphone body for inserting into the pig's ear canal, and a power signal line connected to the temperature sensor is arranged on the other end surface of the earphone body. The earphone body is a truncated cone structure with a hollow interior and openings at both ends, which is not only convenient for the earphone body to be inserted into the pig's ear, but also the middle channel of the earphone body forms a vent, which not only ensures the ventilation of the pig's ear canal, but also avoids affecting the pig's hearing. The setting of the flexible earplug ensures that the earphone body can be installed in the pig's ear more stably, and the temperature sensor can obtain the pig's ear temperature data. The power signal line not only plays the role of power supply and data transmission, avoiding the addition of batteries to the earphone body, but also plays a role in preventing the ear temperature collector from falling to the ground.

[0010] Furthermore, the power signal line is provided with an interface that is detachably connected to the end interface on the earphone body, and a limit ring is provided on the power signal line near the interface. The detachable connection between the power signal line and the earphone body allows the breeder to manually disassemble the ear temperature collector for inspection. At the same time, for cost considerations, only positioning and identification ear tags are installed on some pigs. The setting of the limit ring prevents the power signal line from being completely immersed in the connecting column.

[0011] Furthermore, the ear plug is detachably connected to the contoured wire reel, the contoured wire reel is curved and is arranged to fit the ear plug portion on the pig ear, and the power signal line is located between the contoured wire reel and the pig ear. The configuration of the contoured wire reel allows the power signal line coming out of the connecting post to be connected to the earphone body along the surface of the pig ear contour.

[0012] Furthermore, a sound sensor and a heart rate sensor electrically connected to the power signal line are arranged in the earphone body. The sound sensor and the heart rate sensor can not only detect the pig's breathing and heart rate to reflect the pig's comfort, but also detect the social activities between pigs, so as to reflect the impact of pig social interaction on pig growth.

[0013] Further, the data acquisition module also includes an air collector, the air collector includes a multi-channel rotary joint, the multi-channel rotary joint includes a rotatably connected stator and a rotor, the stator is fixed on the robot, the rotor is connected to the motor fixed on the robot, a fan is provided on the rotor, the fan includes at least four fan blades, the sides of the windward surfaces of the four fan blades are respectively provided with a first air duct, a second air duct, a third air duct and a fourth air duct, the first air duct, the second air duct, the third air duct and the fourth air duct are respectively connected to the air inlet of the first channel, the second channel, the third channel and the fourth channel on the rotor, the air outlet of the first channel, the second channel, the third channel and the fourth channel is located on the stator and is respectively provided with a humidity sensor, an ammonia sensor, a hydrogen sulfide sensor and a carbon dioxide sensor electrically connected to the communication module. Considering that the integration of multiple sensors into one will interfere with the detection accuracy, the detection of a single sensor is achieved by installing sensors in multiple channels on the multi-channel rotary joint, avoiding interaction and improving the detection accuracy. Taking into account that the air at the detection position may have poor circulation or inconsistency, the air flow is achieved by rotating the fan on the rotor, while the external air enters the channels of the multi-channel rotary joint from the multiple air ducts on the fan.

[0014] Furthermore, the axes of the first air duct, the second air duct, the third air duct and the fourth air duct are all streamlined. Such arrangement of the axes of the first air duct, the second air duct, the third air duct and the fourth air duct is conducive to the circulation of air.

[0015] On the other hand, a data collection method of a smart pig farm breeding data collection device is provided, comprising the steps of: S1. Mark multiple pigs evenly distributed in a pig farm as marked pigs, and install multiple temperature collection components on the marked pigs to obtain ear temperature data and positioning information of the marked pigs; S2. Move the track inspection robot to the top of the marked pigs in sequence according to the positioning information, and obtain the body temperature data, humidity data and wind speed data of all pigs in the corresponding marked pig area through the infrared camera, humidity sensor and wind speed sensor respectively; S3, determine whether the ear temperature data of each marked pig is less than the set value. If so, the ear temperature collector may fall off, and arrange staff to reinstall the corresponding ear temperature collector, otherwise proceed to step S4; S4, obtaining the perceived temperature of each marked pig according to the ear temperature data of each marked pig and the relationship between the humidity data and the wind speed data in the marked pig area; S5, analyzing and obtaining a corresponding conversion relationship between the perceived temperature of each marked pig and the body temperature data of each marked pig; S6. Convert the body temperature data of all pigs in the corresponding marked pig area into the perceived body temperature of all pigs according to a plurality of conversion equations.

[0016] In this scheme, the ear temperature data of multiple marked pigs are collected by the marking method, and the body temperature of the marked pigs is obtained by taking into account the influence of humidity and wind speed. The body temperature of all pigs in the entire marked pig area is obtained based on the conversion relationship between the body temperature of each marked pig and the body temperature data of each marked pig. Not only can a more accurate body temperature of the pigs be obtained, but there is no need to test each pig. By obtaining the data of the entire pig farm in a point-to-surface manner, costs can be controlled while facilitating the management of the collection device.

[0017] The present invention discloses a smart pig farm breeding data collection device and method, which has the following beneficial effects: The present invention can obtain stable ear temperature data of pigs through the ear temperature collector, improves the accuracy of collected data, and marks multiple pigs evenly distributed in the pig farm as marked pigs through the marking method, which not only reduces the number of temperature collection components used and reduces costs, but also corrects the pig body temperature data of all pigs in the marked pig area through the precise ear temperature data of each marked pig, and uses the track inspection robot to obtain all the pig body temperature data, humidity data and wind speed data in the corresponding position area, so that the body temperature of the pigs in each area in the entire pig farm can be accurately obtained.

Figure 5 , a plurality of air ducts are arranged on the fan 233 to communicate with the first channel, the second channel, the third channel and the fourth channel respectively. Specifically, the air outlets and air inlets of the first channel, the second channel, the third channel and the fourth channel are arranged on the stator 231 and the rotor 232 respectively, the rotor 232 is connected to the motor fixed on the robot 12 by transmission, the rotor 232 is provided with a fan 233, the fan 233 includes at least four fan blades, and the sides of the windward surfaces of the four fan blades are respectively provided with a first air duct 234, a second air duct 235, a third air duct 236 and a fourth air duct 237, the first air duct 234, the second air duct 235, the third air duct 236 and the fourth air duct 237 are respectively communicated with the air inlets of the first channel, the second channel, the third channel and the fourth channel on the rotor 232.

[0025] In this embodiment, in order to facilitate the circulation of air, the axes of the first air duct 234, the second air duct 235, the third air duct 236 and the fourth air duct 237 are all streamlined.

[0026] refer to Figure 6 The temperature collection component includes a positioning and identification ear tag 3 for locating the pig's position and identifying the pig's identity and an ear temperature collector 4 for detecting the pig's ear temperature. The positioning and identification ear tag 3 is electrically connected to the ear temperature collector 4 and is communicatively connected to the communication module.

[0027] Specifically, as a specific structure of the positioning and identification ear tag 3, refer to Figure 8 The positioning and identification ear tag 3 includes a main tag 31 and an ear plug 32 set on the pig's auricle. The main tag 31 is provided with an installation cavity inside. The installation cavity includes an upper cavity 311 and a lower cavity 312. The upper cavity 311 is provided with a processor and a positioning module electrically connected to the processor, a tag chip, an antenna module and a battery module; the lower cavity 312 is provided with a winding reel 313, and the winding reel 313 is provided with a power signal line 44. The positioning module and the tag chip are used to obtain the pig's location information and the pig's identity information respectively, and transmit them to the data acquisition module 2 through the antenna module.

[0028] refer to Fig. 9 The upper cavity 311 is provided with an end cover 314, and a ring-shaped breathing light 315 is embedded on the end cover 314, and the breathing light 315 is electrically connected to the processor. The breathing light 315 can reflect the state of the pig through different colors. If the pig's body temperature is too high, the breathing light 315 can be red, and if the pig's body temperature is too high, the breathing light 315 can be green, which is convenient for reminding the breeding staff.

[0029] The bottom of the main mark 31 is provided with an internal hollow connection column 316, one end of which passes through the ear hole on the pig's auricle and is fixedly connected to the ear plug 32, and the power signal line 44 passes through the middle of the connection column 316 and the ear plug 32 in turn and is electrically connected to the ear temperature collector 4. The power signal line 44 on the reel 313 passes through the ear plug 32 from the connection column 316 and is electrically connected to the ear temperature collector 4, which not only supplies power to the ear temperature collector 4 and realizes the transmission of ear temperature data, but also has a certain contraction force. After the ear temperature collector 4 is loosened, the ear temperature collector 4 can be recovered on the ear plug 32, avoiding the situation where the ear temperature collector 4 falls off and falls directly to the ground due to the pig's activities, and also avoiding the pig from accidentally eating. At the same time, the contraction force of the reel 313 also ensures that when the pig moves its ears, the power signal line 4 can adaptively change its length to avoid the ear temperature collector 4 being directly pulled off by the pig's ears. The power signal line 44 directly passes through the connection column 316, avoiding routing outside the pig ear and reducing the possibility of the power signal line 44 being pulled.

[0030] Specifically, as the specific structure of the ear temperature collector 4, refer to Fig.10 The ear temperature collector 4 includes an earphone body 41, which is a truncated cone structure with a hollow interior and openings at both ends. The truncated cone structure not only facilitates the earphone body 41 to extend into the pig's ear, but also forms a vent in the middle channel of the earphone body 41, which not only ensures the ventilation of the pig's ear canal, but also avoids affecting the pig's hearing.

[0031] A flexible earplug 42 is sleeved on the conical surface of the earphone body 41, and a temperature sensor 43 is arranged on the small-diameter end surface of the earphone body 41 for inserting into the pig's ear canal, and a power signal line 44 connected to the temperature sensor 43 is arranged on the other end surface of the earphone body 41. The setting of the flexible earplug 42 ensures that the earphone body 41 can be installed in the pig's ear more stably, and the temperature sensor 43 can obtain the pig's ear temperature data. The power signal line 44 not only plays the role of power supply and data transmission to avoid adding batteries to the earphone body 41, but also plays a role in preventing the ear temperature collector 4 from falling to the ground. The temperature sensor 43 can be an infrared temperature sensor or an NTC thermistor temperature sensor.

[0032] In this embodiment, a sound sensor and a heart rate sensor electrically connected to the power signal line 44 are provided in the earphone body 41. The sound sensor and the heart rate sensor can not only detect the pig's breathing and heart rate to reflect the pig's comfort, but also detect the social activities between pigs, which is convenient for reflecting the impact of pig social interaction on pig growth. An audio device is also added to actively output audio to conduct conditioned reflex experiments on pigs.

[0033] The power signal line 44 is provided with an interface that is detachably connected to the end interface on the earphone body 41, and a limit ring is provided near the interface on the power signal line 44. The detachable connection between the power signal line 44 and the earphone body 41 allows the breeder to manually remove the ear temperature collector 4 for maintenance. At the same time, for cost considerations, only the positioning identification ear tag 3 can be installed on some pigs. The setting of the limit ring prevents the power signal line 44 from being completely immersed in the connecting column 316.

[0034] As a further solution of this embodiment, the ear plug 32 is detachably connected to the contoured wire reel 5, the contoured wire reel 5 is curved and is arranged to fit the ear plug 32 on the pig's ear, and the power signal line 44 is located between the contoured wire reel 5 and the pig's ear. The configuration of the contoured wire reel 5 allows the power signal line 44 coming out of the connecting post 316 to be connected to the earphone body 41 along the surface of the pig's ear contour.

[0035] Furthermore, this embodiment also provides a data collection method of a smart pig farm breeding data collection device, comprising the steps of: S1. Mark multiple pigs evenly distributed in a pig farm as marked pigs, and install multiple temperature collection components on the marked pigs to obtain ear temperature data and positioning information of the marked pigs; S2. Move the track inspection robot 1 to the top of the marked pigs in sequence according to the positioning information, and obtain the body temperature data, humidity data and wind speed data of all the pigs in the corresponding marked pig area through the infrared camera 21, humidity sensor 24 and wind speed sensor 22 respectively; S3, determine whether the ear temperature data of each marked pig is less than the set value. If so, the ear temperature collector 4 may fall off, and arrange staff to reinstall the corresponding ear temperature collector 4, otherwise go to step S4; S4, obtaining the perceived temperature of each marked pig according to the ear temperature data of each marked pig and the relationship between the humidity data and the wind speed data in the marked pig area; S5, analyzing and obtaining a corresponding conversion relationship between the perceived temperature of each marked pig and the body temperature data of each marked pig; S6. Convert the body temperature data of all pigs in the corresponding marked pig area into the perceived body temperature of all pigs according to a plurality of conversion equations.

[0036] To summarize, this scheme collects the ear temperature data of multiple marked pigs through the marking method, and obtains the body temperature of the marked pigs by taking into account the influence of humidity and wind speed, and obtains the body temperature of all pigs in the entire marked pig area based on the conversion relationship between the body temperature of each marked pig and the body temperature data of each marked pig. Not only can a more accurate body temperature of the pigs be obtained, but there is no need to test each pig. By obtaining the data of the entire pig farm in a point-to-surface manner, costs can be controlled while facilitating the management of the collection device.
