[0030] In the description of the present invention, the orientations or positional relationships indicated by terms such as "upper", "lower", "above", "both ends", etc. are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Reference Figure 1-3 As shown, this embodiment provides an automated sow estrus detection system, including an estrus detection device 2, the estrus detection device 2 is installed between the rails 1 at the top of the sow stall, the estrus detection device 2 includes an infrared camera assembly 5 and a pressure sensor assembly, the infrared camera assembly 5 is used to identify whether the sow's vulva is red and swollen and whether its temperature is higher than the temperature in the normal state, if the sow's vulva is red and swollen and its temperature is higher, it is marked as stage one, otherwise it is marked as stage zero;

[0032] The pressure sensing component is used to identify whether the sow in the first stage has an arched back phenomenon. If the sow has an arched back phenomenon, it is marked as the second stage, otherwise it is marked as the third stage.

[0033] First, the infrared camera component 5 is used to identify whether the sow is in estrus, and then the sows that are not in estrus can be clearly excluded, thereby reducing the steps of subsequent detection. By using the infrared camera component 5 to replace manual observation, the manual workload is reduced and the detection efficiency can be improved. Then, the sows marked as in estrus by the infrared camera component 5 are detected by the pressure sensor component, and then it can be concluded that the sows in estrus are in the early, middle and late stages of the estrus, which can better remind the breeder to breed the sows in estrus at the stage suitable for breeding, thereby better improving the fertilization rate of the sows.

[0034] Further, the infrared camera assembly 5 includes a first image module and a first temperature monitoring module, the first image module is used to obtain an image of the redness and swelling of the sow's vulva at the current moment and an image of the redness and swelling of the sow's vulva after a preset period of time, and record the image of the redness and swelling of the sow's vulva at the current moment as image one, and record the image of the redness and swelling of the sow's vulva after the preset period of time as image two, and then perform image analysis and comparison on image one and image two;

[0035] The first temperature monitoring module is used to obtain the temperature curve of the sow's vulva at the current moment and the temperature curve of the sow's vulva after a preset period of time, and record the obtained temperature curve of the sow's vulva at the current moment as curve one, and record the obtained temperature curve of the sow's vulva after the preset period of time as curve two, and then perform curve analysis and comparison between curve one and curve two;

[0036] If the redness and swelling of the sow's vulva in Image 1 is stronger than that in Image 2, and the temperature of the sow's vulva in Curve 1 is higher than that in Curve 2, it is recorded as Case 1, otherwise it is recorded as Case 2.

[0037] Since the sow's vulva behaves differently in different stages of estrus, it can be monitored by the first temperature monitoring module and the first image module. By comparing the two sets of data obtained by the first image module and the first temperature monitoring module, it can be roughly determined which stage of estrus the sow is in.

[0038] In the above monitoring, the preset time proposed is 8-10h, but due to the different day and night temperature differences between different regions, the first temperature monitoring module and the first image module are both provided with compensation modules, which can perform adaptive data compensation on the two sets of data acquired according to the day and night temperature difference range set by the user, thereby reducing the impact of the external environment on the monitoring results and greatly improving the accuracy of the monitoring data.

[0039] Further, the pressure sensing assembly includes a pressure sensing module 4 and an extrusion module 3, the pressure sensing module 4 is installed on the lower surface of the middle part of the estrus detection device 2, and the extrusion module 3 is installed on the lower surfaces of both sides of the estrus detection device 2, the pressure sensing module 4 is used to detect the arch back pressure of the sow on the estrus detection device 2 in the stage within the preset time, and the arch back pressure obtained within the preset time is formed into a broken line one, and then the broken line one is compared with the preset standard broken line, if the coupling degree of the broken line one with the preset standard broken line meets more than 78%, it is recorded as situation three, otherwise it is recorded as situation four;

[0040] The squeezing module 3 is used to squeeze the side of the sow in the situation one. If the sow shows a standing reflex during the squeezing process, it is recorded as situation five.

[0041] Since the sow exhibits different behaviors in different stages of estrus, it can be monitored by the pressure sensing module 4 and the extrusion module 3, and the stage of estrus of the sow can be roughly determined based on the data obtained by the pressure sensing module 4 and the extrusion module 3.

[0042] In this test, the preset time is 2-7 minutes.

[0043] Furthermore, the infrared camera assembly 5 and the pressure sensor assembly are both wirelessly connected to the operating platform, and the operating platform is used to receive the situations recorded by the infrared camera assembly 5 and the pressure sensor assembly in real time, and perform statistical analysis on the received situations and compare them with the standard analysis table, and finally output the results of the sow's estrus situation and feed back to the staff's operating system in real time.

[0044] Furthermore, in the standard analysis table, stage zero is the non-estrus state, the simultaneous occurrence of situation two, situation four and situation five is the mid-estrus, the simultaneous occurrence of situation one, situation four and situation five is the late estrus, the simultaneous occurrence of situation one, situation three and situation five is the proestrus, and the simultaneous occurrence of situation two, situation three and situation five is the near-estrus period.

[0045] The infrared camera component 5 is used to identify the condition of the sow's vulva, and based on the identified condition of the sow's vulva, it is determined whether the sow is in estrus or not. If the sow is in estrus, the pressure sensor component is used to simulate the state of artificial back pressure and side compression. Based on the data fed back by the pressure sensor component combined with the data fed back by the infrared camera component 5, it is timely determined which stage of the estrus the sow is in, which makes it more convenient for the breeder to breed the sow in time.

[0046] Furthermore, the infrared camera assembly 5 also includes a second image module, which is used to obtain the color of the mucus secreted from the sow's vulva, and compare the obtained color of the mucus secreted from the sow's vulva with the standard color. If the obtained color of the mucus secreted from the sow's vulva is inconsistent with the standard color, it is marked as a state to be treated; if the obtained color of the mucus secreted from the sow's vulva is consistent with the standard color, it is marked as a state to be bred.

[0047] The color of the mucus secreted from the vulva of the sow in estrus is obtained according to the second image module, and the health of the sow's uterus is judged according to the obtained color data. That is, if the color of the mucus secreted from the vulva of the sow is not transparent, it means that the sow suffers from endometritis, which reminds the breeder to give priority to its treatment, protect the health of the sow's uterus, and avoid economic losses.

[0048] Furthermore, the second image module further includes:

[0049] An acquisition unit, the acquisition unit is used to acquire an image of mucus secreted from the vulva of the sow, recorded as a first image;

[0050] An enlargement unit, the enlargement unit is used to enlarge and cut a region of the acquired first image to form a second image;
