[0034] At present, some wearable devices for individual livestock are proposed in smart agriculture, for example, a patent with application number 202210746107.5 proposes a wearable methane breathing filtering device for dairy cows. During the working process of these wearable devices, it is often necessary to detect whether the livestock needs to feed (eat, drink water) to control the intelligent opening and closing of the wearable device. Based on this, the embodiments of the present application provide a device and method for detecting livestock feeding, the device comprising: a first detection mechanism, a second detection mechanism and a fixing mechanism; the first detection mechanism and the second detection mechanism are fixedly connected with the fixing mechanism; the first detection mechanism comprises a first resistive conductive glass tube and a detection air bag, the first resistive conductive glass tube movably has a conductive piece inside the conductive glass tube, which moves up and down inside the conductive glass tube and tilts with the conductive piece; the upper end of the resistive conductive glass tube is provided with a first output electrode and a second output electrode, the sliding end of the second output electrode is movably connected with the conductive piece, so as to change the output resistance of the first resistive conductive glass tube based on the position of the conductive piece; the detection air bag is in communication with the lower end opening of the first resistive conductive glass tube, so as to be deformed by being squeezed when the livestock feeds, changing the position of the conductive piece; the second detection mechanism comprises a second resistive conductive glass tube and a reference air bag, the second resistive conductive glass tube has the same structure as the first resistive conductive glass tube; the reference air bag has the same volume as the detection air bag, and the reference air bag is in communication with the lower end opening of the second resistive conductive glass tube; in this way, under normal circumstances, the detection air bag of the first detection mechanism and the reference air bag of the second detection mechanism are not deformed, and the output resistances of the first detection mechanism and the second detection mechanism are the same under normal circumstances; when the livestock feeds, the detection air bag of the first detection mechanism is deformed by being squeezed, and the reference air bag of the second detection mechanism is still not deformed, the positions of the conductive pieces in the first resistive conductive glass tube and the second resistive conductive glass tube are different, the detection resistance signal sent by the first detection mechanism and the reference resistance signal sent by the second detection mechanism are not equal, so as to determine that the livestock feeds.

[0035] Please refer to Figure 1 , Figure 1 The structure of the device for detecting livestock feeding is shown in the schematic diagram; specifically, the device for detecting livestock feeding comprises a first detection mechanism, a second detection mechanism and a fixing mechanism; the first detection mechanism and the second detection mechanism are fixedly connected with the fixing mechanism;

[0036] The first detection mechanism includes a first resistive conductive glass tube 1 and a detection airbag 2. The first resistive conductive glass tube 1 is provided with a conductive member 3 that moves up and down within the conductive glass tube and tilts as the conductive member 3 tilts. The upper end of the resistive conductive glass tube is provided with a first output electrode 4 and a second output electrode 5. The sliding end of the second output electrode 5 is movably connected to the conductive member 3 to change the output resistance of the first resistive conductive glass tube 1 based on the position of the conductive member 3.

[0037] The detection airbag 2 is connected to the lower end opening of the first resistive conductive glass tube 1 so as to be squeezed and deformed when the livestock eats, thereby changing the position of the conductive member 3;

[0038] The second detection mechanism includes a second resistive conductive glass tube 6 and a reference airbag 7. The second resistive conductive glass tube 6 has the same structure as the first resistive conductive glass tube 1; the reference airbag 7 has the same volume as the detection airbag 2, and the reference airbag 7 is connected to the lower end opening of the second resistive conductive glass tube 6.

[0039] The second resistive conductive glass tube 6 has the same structure as the first resistive conductive glass tube 1, that is, the second resistive conductive glass tube 6 is provided with a conductive member 3 that moves up and down inside the conductive glass tube and tilts as the conductive member 3 tilts; the upper end of the resistive conductive glass tube is provided with a first output electrode 4 and a second output electrode 5, and the sliding end of the second output electrode 5 is movably connected to the conductive member 3 to change the output resistance of the second resistive conductive glass tube 6 based on the position of the conductive member 3.

[0040] Please refer to Figure 1 The detection airbag 2 of the first detection mechanism communicates with the sealed space below the first resistive conductive glass tube 1 via a first communication port 8. The reference airbag 7 of the first detection mechanism communicates with the sealed space below the second resistive conductive glass tube 6 via a second communication port 9. In this embodiment, the detection airbag 2 is located at the lower end of the first resistive conductive glass tube 1 so that it can contact and be squeezed by the forage. The reference airbag 7 is positioned parallel to the second resistive conductive glass tube 6 to avoid contact with the forage.

[0041] Here, the conductive member 3 divides the resistive conductive glass tube into an upper sealed space and a lower sealed space, both of which are filled with an inert gas. Similarly, the detection airbag 2 of the first detection mechanism and the reference airbag 7 of the second detection mechanism are also filled with an inert gas.

[0042] The device described in the embodiment of the application is arranged at the nose of the cow, and the electrically conductive member 3 arranged movably in the electrically conductive glass tube moves up and down and tilts with the tilting of the electrically conductive member 3, and the first output electrode 4 and the second output electrode 5 of the electrically conductive glass tube and the part above the electrically conductive member 3 in the electrically conductive glass tube constitute a variable resistor; in this way, the position of the electrically conductive member 3 changes (moves up and down or tilts), and the output resistance between the first output electrode 4 and the second output electrode 5 of the electrically conductive glass tube also changes.

[0043] When the cow raises or lowers its head, the electrically conductive member 3 of the first electrically conductive glass tube 1 of the first detection mechanism and the electrically conductive member 3 of the second electrically conductive glass tube 6 of the second detection mechanism tilt synchronously under the action of gravity and are in the same position in the corresponding electrically conductive glass tube; the detection resistance output by the first detection mechanism and the reference resistance output by the second detection mechanism are the same.

[0044] The detection air bag 2 of the first detection mechanism in the embodiment of the application is squeezed when the cow feeds, and the inert gas in the air bag enters the lower sealing space of the first electrically conductive glass tube 1 and pushes the electrically conductive member 3 of the first electrically conductive glass tube 1 to move upward, while the reference air bag 7 of the second detection mechanism is not squeezed when the cow feeds, so that the electrically conductive member 3 of the second electrically conductive glass tube 6 of the second detection mechanism does not move upward.

[0045] That is, when the livestock feeds, the electrically conductive member 3 of the first electrically conductive glass tube 1 of the first detection mechanism moves upward, and the electrically conductive member 3 of the second electrically conductive glass tube 6 of the second detection mechanism does not move, and the positions in the corresponding electrically conductive glass tube are different; the detection resistance output by the first detection mechanism and the reference resistance output by the second detection mechanism are different; in the embodiment of the application, the detection resistance output by the first detection mechanism is smaller than the reference resistance output by the second detection mechanism.

[0046] In addition, the device described in the embodiment of the application can also be used to detect the head posture of the livestock; the horizontal resistance threshold range when the head of the livestock is horizontal is obtained, the detection resistance output by the first detection mechanism is set as R1, and the reference resistance output by the second detection mechanism is set as R2, so that when the reference resistance R2 meets the horizontal resistance threshold range, it indicates that the head of the livestock is horizontal; when the reference resistance R2 is smaller than the horizontal resistance threshold range, it indicates that the head of the livestock is in a raised state; and when the reference resistance R2 is greater than the horizontal resistance threshold range, it indicates that the head of the livestock is in a lowered state.

[0047] Here, the reason why the reference resistance R2 output by the second detection mechanism is used to judge the head posture of the livestock is that the reference air bag 7 with the reference resistance R2 output by the second detection mechanism does not deform and is less disturbed.

[0048] In the embodiment of the present application, the conductive member 3 is a conductive liquid, such as mercury.

[0049] Please refer to Figure 1 The first detection mechanism and the second detection mechanism are fixedly connected with the fixing mechanism; the fixing mechanism comprises a base, the reference air bag 7 and the second electrically conductive glass tube 6 of the second detection mechanism are vertically and parallelly arranged, and are fixed on the upper end face of the base; the lower end of the first electrically conductive glass tube 1 of the first detection mechanism is flush with the upper end face of the base, the detection air bag 2 is located below, or in front of, or in front and below, the first electrically conductive glass tube 1, so as to facilitate the livestock to squeeze the detection air bag 2 when drinking water or eating.

[0050] For example, the detection air bag 2 is fixed on the front end face of the base, and is specifically fixed by the air bag limiting assembly arranged on the front end face. The air bag limiting block 10 can prevent the air bag from being excessively squeezed by the forage food.

[0051] The air bag limiting assembly can be the air bag limiting block 10 arranged at both ends of the detection air bag 2.

[0052] In some cases, it is necessary to more accurately detect whether the livestock is in a water drinking state or a food eating state. Based on this, please refer to Figure 1 The first detection mechanism further comprises a water-absorbing expansion block 12, and the detection air bag 2 is located inside the water-absorbing expansion block 12, so as to be squeezed and deformed by the water-absorbing expansion block 12 when the livestock drinks water, and the position of the conductive member 3 is changed.

[0053] For example, the detection air bag 2 is clamped between a plurality of water-absorbing expansion blocks 12, or is sleeved inside the water-absorbing expansion block 12.

[0054] In the embodiment of the present application, the detection air bag 2 is in a portal shape, and the portal-shaped detection air bag 2 comprises two fixed ends; each end is fixedly connected with the base through the air bag limiting block 10; in other words, the fixed end of the detection air bag 2 is sleeved in the air bag limiting block 10, so as to be fixedly connected with the base through the air bag limiting block 10.

[0055] Based on this, please refer to Figure 1 The inner side wall of the air bag limiting block 10 in contact with the air bag is provided with an expansion groove 11; the water-absorbing expansion block 12 is fixed in the expansion groove 11, so as to squeeze the detection air bag 2 located between the two water-absorbing expansion blocks 12 after water absorption and expansion.

[0056] The gas pressure when the detection airbag 2 is not squeezed is set to P limit, and the corresponding detection resistance R1 is R limit. Therefore, when the detection airbag 2 is squeezed during eating, the pressure generated must be less than P limit, and the detection resistance R1 must be greater than R limit. In order to better identify eating and drinking, the water absorption expansion block 12 is set to absorb water and the pressure generated on the airbag is slightly greater than P0, and the corresponding resistance is slightly less than R limit.

[0057] Specifically, by designing the expansion coefficient of the water-absorbing expansion block 12, the pressure exerted by the water-absorbing expansion block 12 on the detection airbag 2 when the livestock drinks water is greater than the pressure exerted on the detection airbag 2 when the livestock eats, thereby achieving the purpose of pressure bias and setting the drinking pressure and eating pressure within different ranges.

[0058] The water-absorbing and expanding block 12 absorbs water and expands when the livestock drinks water, squeezing the inert gas in the airbag into the lower sealed space of the first resistive conductive glass tube 1, thereby pushing the conductive member 3 to move upward and changing the position of the conductive member 3. The detection resistance R1 output by the first detection mechanism will be smaller than the reference resistance R2 output by the first detection mechanism.

[0059] The detection airbag 2 is deformed by the expanded water-absorbing expansion block 12 when the livestock drinks water, and deformed by the feed when the livestock eats, and the deformation degree is different;

[0060] The first detection mechanism outputs a drinking resistance signal within a drinking threshold range when the livestock drinks water; the first detection mechanism outputs a feeding resistance signal within a feeding threshold range when the livestock eats.

[0061] In the embodiment of the present application, the volume of the water absorption expansion block 12 and the airbag limiting block 10 is set to determine the deformation degree of the detection airbag 2 when the livestock is eating and drinking.

[0062] For example, in order to better identify eating and drinking, it is set that when the water-absorbing expansion block 12 absorbs water and squeezes the airbag, the pressure generated by the airbag is slightly greater than the target pressure P0, and when the grass squeezes the airbag, the pressure generated by the airbag is slightly less than the target pressure P0. In this way, taking the example of the large degree of squeezing and deformation of the expanded water-absorbing expansion block 12 and the small degree of squeezing and deformation when the livestock is squeezed and deformed by the feed when eating, the drinking threshold range of the detection resistor R1 output by the first detection mechanism is smaller than the eating threshold range.

[0063] For example, the resistance threshold R is set to distinguish between the drinking threshold range and the eating threshold range. yuzhiThat is, when the detection resistance R1 output by the first detection mechanism is equal to the reference resistance R2 output by the second detection mechanism, the livestock is not eating (the head of the livestock can be in any of the horizontal, head-up, and head-down postures); when the detection resistance R1 output by the first detection mechanism is less than the reference resistance R2 output by the second detection mechanism, the livestock is eating; when the detection resistance R1 output by the first detection mechanism is less than the reference resistance R2 output by the second detection mechanism and R1 is less than R yuzhi , it is determined that the livestock is in the head-down eating state; when the detection resistance R1 output by the first detection mechanism is less than the reference resistance R2 output by the second detection mechanism and R1 is greater than R yuzhi , it is determined that the livestock is in the head-down drinking state.

[0064] In the device for detecting eating of livestock in the embodiment of the application, the first output electrode 4 and the second output electrode 5 of the first resistance conductive glass tube 1 in the first detection mechanism heat the upper sealed space of the first resistance conductive glass tube 1, so that the inert gas in the upper sealed space of the first resistance conductive glass tube 1 expands and pushes the conductive part 3 in the first resistance conductive glass tube 1 to move downward, and pushes the inert gas in the lower sealed space into the detection air bag 2, so that the detection air bag 2 expands.

[0065] That is, when the first output electrode 4 and the second output electrode 5 of the first resistance conductive glass tube 1 are connected to the heating circuit, the first output electrode 4, the upper sealed space of the first resistance conductive glass tube 1, the mercury, and the second output electrode 5 constitute the heating circuit, the upper sealed space is heated, the inert gas in the upper sealed space expands under the heat, pushes the conductive part 3 in the first resistance conductive glass tube 1 to move downward, and pushes the inert gas in the lower sealed space into the detection air bag 2, so that the detection air bag 2 expands, the conductive part 3 of the first detection mechanism resets, and at the same time, the water in the water-absorbing and expanding block 12 is squeezed out when the air bag expands, so that the preparation work for the next measurement of drinking water of the livestock is completed.

[0066] In the device for detecting eating of livestock in the embodiment of the application, when the conductive part 3 in the first resistance conductive glass tube 1 moves downward and separates from the second output electrode 5 of the fixed length, the heating of the upper sealed space of the first resistance conductive glass tube 1 is stopped.

[0067] That is, the first output electrode 4, the upper sealed space portion of the first resistive conductive glass tube 1, the mercury and the second output electrode 5 constitute a heating circuit, the upper sealed space is heated, the inert gas in the upper sealed space expands under the heat, pushes the conductive piece 3 in the first resistive conductive glass tube 1 to move downward constantly, until the second output electrode 5 separates from the conductive piece 3, the heating circuit is disconnected, the heating stops, as the heat in the upper sealed space dissipates, and the moisture in the moisture absorbing and expanding block 12 is squeezed out, the first detection mechanism resets, ready for the next drinking water detection.

[0068] In some embodiments, a method for detecting livestock eating is also provided, applied to a processor, please refer to Figure 2 , the processor 201 is electrically connected with the livestock eating detection device 202; please refer to Figure 3 , the method comprises the following steps S301-S303:

[0069] S301, receiving the detection resistance signal sent by the first detection mechanism of the livestock eating detection device, and the reference resistance signal sent by the second detection mechanism;

[0070] S302, comparing the detection resistance signal and the reference resistance signal;

[0071] S303, if the detection resistance signal and the reference resistance signal are not equal, it is determined that the livestock eats.

[0072] Here, the processor is electrically connected with the livestock eating detection device, and the processor can be electrically connected with the livestock eating detection device through a resistance acquisition circuit, so as to acquire the detection resistance signal sent by the first detection mechanism and the reference resistance signal sent by the second detection mechanism of the livestock eating detection device.

[0073] The embodiment of the present application provides a method for detecting livestock feeding, which is applied to a processor, and the processor is electrically connected with the livestock feeding detection device, the device comprises a first detection mechanism, a second detection mechanism and a fixing mechanism; the first detection mechanism and the second detection mechanism are fixedly connected with the fixing mechanism; the first detection mechanism comprises a first resistance conductive glass tube 1 and a detection air bag 2, the first resistance conductive glass tube 1 is internally movably provided with a conductive element 3 which moves up and down in the conductive glass tube and tilts with the conductive element 3; the upper end of the resistance conductive glass tube is provided with a first output electrode 4 and a second output electrode 5, the sliding end of the second output electrode 5 is movably connected with the conductive element 3, so that the output resistance of the first resistance conductive glass tube 1 is changed based on the position of the conductive element 3; the detection air bag 2 is in open communication with the lower end of the first resistance conductive glass tube 1, so as to be deformed by being squeezed when the livestock feeds and change the position of the conductive element 3; the second detection mechanism comprises a second resistance conductive glass tube 6 and a reference air bag 7, the second resistance conductive glass tube 6 is the same as the first resistance conductive glass tube 1 in structure; the reference air bag 7 is the same in volume with the detection air bag 2, and the lower end of the reference air bag 7 is in open communication with the second resistance conductive glass tube 6; in this way, under normal circumstances, the detection air bag 2 of the first detection mechanism and the reference air bag 7 of the second detection mechanism are not deformed, and the output resistances of the first detection mechanism and the second detection mechanism are the same under normal circumstances; when the livestock feeds, the detection air bag 2 of the first detection mechanism is deformed by being squeezed, the reference air bag 7 of the second detection mechanism is still not deformed, the positions of the conductive elements 3 in the first resistance conductive glass tube 1 and the second resistance conductive glass tube 6 are different, the detection resistance signal sent by the first detection mechanism and the reference resistance signal sent by the second detection mechanism are not equal, so that the livestock feeding is determined.

[0074] In some embodiments, referring to Figure 4 In the method for detecting livestock feeding, if the detection resistance signal and the reference resistance signal are not equal, the livestock feeding is determined, which comprises the following steps S401-S403:

[0075] S401, if the detection resistance signal and the reference resistance signal are not equal, the detection resistance signal is compared with a preset drinking water threshold range and a preset feeding threshold range;
