Second, manual contact assessment relies on experience, and due to differences in experience and judgment criteria among different personnel, the evaluation results are not accurate enough. In addition, manual scoring methods are usually qualitative and lack precise quantitative standards. Summary of the invention

[0050] The embodiment of the present invention further provides a method for detecting the fullness of the rumen of a dairy cow, and its flow chart is as follows: Figure 8As shown, the rumen filling degree measuring device needs to be placed in the area from the last rib to the ilium in the left rumen of the cow, and the upper edge of the device body is parallel to the upper edge of the rumen of the cow. The method for detecting the rumen filling degree of the cow includes the following steps:

[0051] S1. Data collection: After pressing the power switch, press the measurement button, the device starts working, and the ultrasonic ranging module collects N ranging values ​​for each ultrasonic ranging module according to the serial number, and transmits each collected N ranging value and the coordinate value corresponding to the ultrasonic ranging module as a ranging set to the storage unit.

[0052] Since the intervals between the ultrasonic ranging modules are relatively small, mutual interference will occur when measuring the distance at the same time, resulting in large errors in the measurement results. Therefore, the embodiment of the present invention improves the ranging mode of the ultrasonic ranging module by changing it to time-sharing measurement, and measures the distance in sequence according to the number of the ultrasonic ranging module, thereby ensuring that there is no interference between them.

[0053] S2. Data screening: The calculation unit performs the following calculations on each set of ultrasonic ranging sets: remove a maximum value and a minimum value from each set of ranging sets and calculate the average value, which is used as the ranging result of each ultrasonic ranging module; screen the ranging results, and record the coordinates whose ranging results are less than a set threshold. A set threshold provided in the embodiment of the present invention is 0.1 cm. Suppose the area enclosed by these coordinates is S, calculate all ranging results, screen the coordinates whose ranging coordinates fall within S, and record the coordinate information and ranging results.

[0054] The method for calculating the average value of the measured distance in the embodiment of the present invention is as follows:

[0055]

[0056] in express The distance measurement value corresponding to the coordinate, n represents the number of measurements, express The i-th distance measurement value under the coordinate, express The maximum value under the coordinates, express The minimum value under the coordinates.

[0057] The specific data screening calculation method is as follows: Assume that the distance measurement value collected by the ultrasonic ranging module is expressed as ,in and is the horizontal and vertical coordinates of the measuring point, in centimeters. The following is the screening formula:

[0058] Suppose the coordinate point set corresponding to the ultrasonic ranging module is:

[0059] ;

[0060] The coordinates of the point to be determined are: ;

[0061] Defining functions To indicate the range of the horizontal axis when the vertical axis is y:

[0062] If y=0, then ,in , .

[0063] If y=1, then ,in , .

[0064] By analogy, determine the distance value The formula for whether it is within a given coordinate area is:

[0065] like ,but ,Right now ,in , , and thus, through the above judgment, the target points that meet the conditions are Filter out.

[0066] S3. Calculation of quantified value of rumen filling: Obtain the results of the above data screening, and take the ratio of the sum of the distance measurement results and the area S as the quantified value of rumen filling. The larger the quantified value of rumen filling, the worse the rumen filling, and vice versa, the better the rumen filling. Specifically:

[0067] Calculate the quantitative value of rumen filling, and select the distance measurement value that meets the conditions after filtering the above data The ratio of the sum of the corresponding area is the quantitative value of rumen filling, and the calculation formula is as follows:

[0068]

[0069]

[0070] in is the quantitative value of rumen filling, z is the number of distance measurement results after data screening, is the area of ​​the corresponding target area in the rumen, is the corresponding width of the ultrasonic ranging module, is the corresponding height of the ultrasonic ranging module. For better data representation, the final result is multiplied by 100 in the embodiment of the present invention.

[0071] S4. Fullness score: The quantified value of rumen fullness is converted into a fullness score, with a maximum of 5 points and a minimum of 1 point. The larger the score, the higher the rumen fullness.

[0072] In the embodiment of the present invention, according to the calculated quantification value of rumen filling Converted to rumen filling score, the conversion score rules are as follows:

[0073] , the score is 1 point;

[0074] , the score is 2 points;

[0075] , the score is 3 points;

[0076] , with a score of 4 points;

[0077] , with a score of 5;

[0078] In an embodiment of the present invention, The value of is obtained by evaluating 730 Holstein cows of different ages and production cycles in an actual production environment. The evaluation scores are compared with the above quantified values ​​of rumen filling. A specific value is given as follows: , , , .

[0079] In summary, the present invention uses a plurality of ultrasonic ranging modules to form an ultrasonic ranging module, performs multiple measurements on the measured area to form a measurement set, calculates and screens the data of the measurement set to obtain a quantified value of rumen fullness, then converts the quantified value into a rumen fullness score, transmits it to a display unit for display, and saves the rumen fullness score through a storage unit.
