First embodiment
Referring to fig. 1, the present embodiment provides an animal ruminant monitoring device 100, wherein the animal ruminant monitoring device 100 is configured to be sleeved at the root of the mouth of the animal, and includes a stretchable resistor chain 110 and a processor 120, and the stretchable resistor chain 110 is electrically connected with the processor 120.
Referring to fig. 2, the stretchable resistor chain 110 is in a chain shape, and is connected end to form a closed loop sleeved at the root of the mouth of the animal. Wherein the stretchable resistor chain 110 comprises a plurality of stretchable cells 111 connected in sequence.
Referring to fig. 3, each stretchable unit 111 comprises: a first magnet 112, a second magnet 113, a stop ring 114, a resistor 115, and a conductive sleeve 116. The resistor 115 is arranged on the conductive sleeve 116, openings are formed at two ends of the conductive sleeve 116, one end of the conductive sleeve 116 is sleeved on the first magnet 112 through the openings, and the other end of the conductive sleeve 116 is sleeved on the second magnet 113 through the openings.
The two ends of the first magnet 112 and the second magnet 113 are respectively sleeved with a baffle ring 114. The baffle ring 114 may be made of a non-magnetic material, and the baffle ring 114 has a size larger than the size of the opening. The baffle ring 114 of the first magnet 112 far from the second magnet 113 is arranged outside the conductive sleeve 116, and the baffle ring 114 of the second magnet 113 far from the first magnet 112 is also arranged outside the conductive sleeve 116, so that the first magnet 112 and the second magnet 113 are prevented from being separated from the conductive sleeve 116 in the process of pulling by external force.
The conductive sleeve 116 is made of a conductive material to perform a conductive function. Generally, common conductive materials are metals, semiconductors, and the like. In this embodiment, the conductive sleeve 116 is preferably made of a metallic material. Referring to fig. 4, as an embodiment, the conductive sleeve 116 may be cylindrical, and the cross section of the conductive sleeve is circular, and the resistor 115 is also circular, and the resistor 115 is embedded in the conductive sleeve 116 along a direction perpendicular to a radial direction of the conductive sleeve 116.
Let the lengths of the first magnet 112 and the second magnet 113 be L 0 As one embodiment, L 0 May be 5mm, and the resistance of resistor 115 is R 1 . In an ideal case, the resistance value of the first magnet 112 and the second magnet 113 is 0 ohm, but in a practical case, the resistance value R exists between the first magnet 112 and the second magnet 113 0 R is taken 1 Far greater than R 0 。
The stretchable element 111 is not exposed to the outsideWhen the first magnet 112 and the second magnet 113 are pulled, they can be attracted together by the attractive force therebetween to be in close contact. At this time due to R 1 Far greater than R 0 ，R 1 Is short-circuited, the resistance access value of the stretchable element 111 is 2R 0 。
Referring to fig. 5, when the stretchable unit 111 is pulled by an external force as indicated by an arrow, the first magnet 112 and the second magnet 113 are stretched apart, and at this time, the resistor 115 is turned on, and the resistance of the stretchable unit 111 has an access value R 1 (due to R 1 Far greater than R 0 Thus R is 0 Is negligible).
When the stretchable resistor chain 110 formed by the stretchable units 111 is sleeved at the root of the mouth of an animal, the stretchable resistor chain 110 is stretched in the chewing process of the animal, and the stretching process enables the first magnet 112 and the second magnet 113 to be disjointed, so that the first magnet 112 and the second magnet 113 cannot be separated from the conductive sleeve 116 due to the limiting function of the baffle ring 114.
Therefore, it is only necessary to know that the resistance value of the stretchable resistor chain 110 is N R 1 It can be seen that the length of the stretchable resistor chain 110 varies by n×l 0 The opening and closing degree of the animal mouth root can be represented by the number of the connected resistors 115 in the stretchable resistor chain 110. The greater N indicates a greater degree of mouth opening in the animal.
Accordingly, the resistance values in the stretchable resistor chain 110 are different, as are the voltage values in the access processor 120. When the processor 120 receives the resistance variation data, the number of the connected resistors 115 in the stretchable resistor chain 110 can be calculated based on the resistance variation data. The processor 120 may include a single-chip microcomputer and an amplifier, please refer to fig. 6, vi is an analog output terminal of a DAC controlled by the single-chip microcomputer, V O The analog input end of the ADC is controlled by the singlechip, and Vcc is a limiting voltage quantity. In the figure, R represents a resistor 115, and RL is the total on resistance of the chain 110 during actual measurement.
In order to reduce the error in the number of switches in the resistor 115 in the resistor chain 110 calculated by the processor 120, as an embodiment, the reference voltage Vi of the amplifier portion in the processor 120 may vary with the number of switches in the resistor chain 110. Let vi=vcc/(n+1) in the initial process, where N is the total number of resistors 115 in the stretchable resistor chain 110, and Vo is measured; if Vo < = VCC; n=vcc/Vo; n is an integer part; let vi=n VCC/(n+1) before the next measurement; if Vo > VCC; n=vo/VCC; n=n (integer part) +1; let vi=vcc/N (n+1) before the next measurement; the number of resistors is nr= (Vo/Vi) -1. The resistance access value in the stretchable resistor chain 110 is thus obtained.
The animal rumination monitoring device monitors the resistance access value in the stretchable resistor chain 110 in real time, and the singlechip compares the resistance access value with a preset value stored in a memory in advance. And obtaining a current time value every time the resistance access number is larger than or equal to the preset number. After a plurality of time values are generated by at least two comparison, the singlechip calculates and obtains a chewing period based on the two continuously generated time values, compares the chewing period with a preset reference period, and judges that the animal is in a ruminant state if the chewing period is larger than the preset reference period. The preset number can be obtained through a statistical rule, and the resistor in the stretchable resistor chain 110 is connected to the number when the opening degree of the mouth of the animal reaches the maximum degree. When the resistance access number exceeds a preset number, recording the moment T0 at the moment, and similarly, recording the moment T1 when the resistance access number exceeds the preset number, wherein the chewing period T=t1-T0 of the animal, and the T0 and the T1 are two continuously generated time values.
Animals such as cattle and the like chew fast in the chewing process, chew slow in the ruminant, so that a reference period is preset as T0 in the singlechip, and T0 can also be obtained through a statistical rule. When T is greater than T0, the animal is judged to be in a ruminant condition.
In order to make the monitoring accuracy of the animal ruminant monitoring device 100 more accurate, and to avoid the occurrence of erroneous judgment, as an embodiment, please refer to fig. 7, the animal ruminant monitoring device 100 further includes a gesture sensor 130, the gesture sensor 130 being electrically connected to the processor 120, wherein the gesture sensor 130 may be a six-axis sensor. When the ruminant monitoring device 100 is sleeved at the root of an animal mouth, the attitude sensor 130 can be arranged on the frontal bone of the animal, and is used for acquiring attitude data representing the attitude of the head of the animal. Animal rumination monitoring device 100 may combine the chew cycle and pose data to determine the rumination of the animal.
The processor 120 receives the gesture data, compares the gesture data with a preset reference value, and determines that the animal is in a ruminant state if the mastication period is greater than the preset reference period and the gesture data characterizes the animal head in a first gesture. The preset reference value may be a range, for example, taking a horizontal inclined downward of 40 degrees to 55 degrees as an example, which indicates that the head of the animal is in a horizontal state, and when the inclination angle is 56 degrees to 90 degrees, the animal is in a first posture, that is, the head of the animal is in a posture facing the ground.
To enable animal rumination monitoring device 100 to feed back the rumination of the animal to the staff in real time, referring to fig. 8, animal rumination monitoring device 100, as one embodiment, further comprises a wireless communication transmission module 140 electrically connected to processor 120. The wireless communication transmitting module 140 is used for transmitting the result representing that the animal is in the ruminant state to the data receiving terminal which can be in data communication with the wireless communication transmitting module 140, so that a worker can check the data collected by the animal ruminant monitoring device 100 through the data receiving terminal.
Further, the wireless communication transmitting module 140 may be a bluetooth communication module or a WiFi communication module.
As the animal grows continuously, the size of the animal's mouth root also increases as it grows. Since the growth rate is a very slow process, a short time does not affect the monitoring process of the ruminant monitoring apparatus 100, but in the long term, an increase in the size of the mouth root may exert a tensile force on the tensile resistor chain 110, affecting the monitoring process of the ruminant monitoring apparatus 100. Thus, referring to fig. 9, as one embodiment, animal ruminant monitoring device 100 further includes a bladder 150 made of an elastic material. One end of the air bag 150 is connected to one end of the stretchable resistor chain 110, and the other end of the air bag 150 is connected to the other end of the stretchable resistor chain 110, that is, the air bag 150 and the stretchable resistor chain 110 together form a closed loop.
Referring to fig. 10, an air vent hole 151 is provided in the air bag 150. When the air bag 150 is inflated with air, the air release hole 151 releases the air in the air bag 150 quickly when the air bag 150 receives the tensile force indicated by the arrow direction in the figure, so that the volume of the air bag 150 is reduced, and the distance between the two ends of the air bag 150 receiving the tensile force is increased, thereby achieving the purpose of adapting to animal growth.
