Description

Technical Field

[0001] The invention belongs to the technical field of intelligent livestock data collection, and in particular relates to a livestock data collection terminal and a data collection method. Background Art

[0002] Acquiring head size data (including length and circumferential dimensions corresponding to multiple parts) of livestock represented by pigs, cattle, and sheep has always been a technical difficulty in this field. The current operation method is mainly to fix the livestock to be measured (such as tying or clamping), and then the operator pulls a tape measure to measure. However, there are many disadvantages in the actual operation process: the operation is very difficult, requiring at least three people to cooperate with each other to complete; it is easy to cause injury to the operator, especially for cattle and pigs with bad tempers, which can easily cause injury to the operator; the efficiency is low, and it usually takes 30 to 60 minutes to complete the acquisition of the head size data of a measured livestock; more importantly, the data of many parts (such as the distance between the two ears of the measured livestock, the two ears of the livestock will always flutter intermittently) cannot be accurately obtained. Summary of the invention

[0003] At least in order to solve the problems existing in the background technology, the present invention provides a livestock data collection terminal and a data collection method.

[0006] Preferably, the distance between adjacent distance measuring sensors is no more than 3 cm.

[0007] In order to increase the service life of the livestock data collection terminal, a flexible layer is provided on the inner wall of the shell, and the surface of the flexible layer is not lower than the front end of the distance measuring sensor.

[0008] Preferably, the shell is made of magnesium alloy or aluminum alloy.

[0025] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0026] Combination Figure 1 and Figure 2 As shown, a livestock data acquisition terminal comprises a controller and a power supply arranged on a shell 1, the controller and the power supply are installed inside a waterproof cover 4, the shell 1 is in a cylindrical shape with two ends open, the inner cavity diameter of the shell 1 is larger than the size of the thickest part of the head of the livestock to be measured, a through hole 2 is arranged on the shell 1, and the axis of the through hole 2 is perpendicular to and intersects with the axis of the shell 1; a plurality of distance measuring sensors 3 arranged in an array are arranged inside the shell 1, and the light paths emitted by all the distance measuring sensors 3 are perpendicular to and intersect with the axis of the shell 1; the reference points of all the distance measuring sensors 3 are evenly arranged around the axis of the shell 1, all the distance measuring sensors 3 are connected to the controller and the power supply, and the distance data obtained by the distance measuring sensors 3 can be fed back to the computer control system in real time.

[0027] In this embodiment, the distance between adjacent distance measuring sensors 3 is controlled to be 2 cm; a flexible layer (silicone) is provided on the inner wall of the shell 1, and the surface of the flexible layer is not lower than the front end of the distance measuring sensor 3; the shell 1 is made of magnesium alloy, and a handle is provided on the top of the shell 1.

[0028] A data collection method using the livestock data collection terminal of this embodiment is used to collect the size data of the pig's head, and the steps include:

[0029] S1, according to the selected livestock data collection terminal, the model of the livestock data collection terminal is obtained according to the 1:1 arm strength model;

[0030] S2, fix the livestock data collection terminal at a designated location in the livestock farm or operate it by hand during measurement; then guide the head of the livestock (pig) to be measured to extend into the inner cavity of the shell 1, and the state at this time is as follows Figure 2 As shown, a rope can be used to tie the food used to induce the livestock to be measured, and then the food can be extended into the inner cavity of the shell 1 through the through hole 2; it should be noted that when selecting the specifications of the livestock data collection terminal, the inner cavity diameter of the shell 1 should be as large as possible as much as possible as much as possible as much as possible. The diameter of the thickest part of the head of the livestock to be measured (diameter) is 1.5 times larger, so that the surface of the head of the livestock to be measured can be prevented from touching the front end of the distance measuring sensor 3 and affecting the measurement result;

[0031] S3, control all the distance measuring sensors 3 to be turned on at the same time. At this time, the light paths / light beams 5 emitted by all the distance measuring sensors 3 in the same radial section are as follows: Figure 2 As shown, at this time, the distance L from the reference point of each distance measuring sensor 3 to the head surface of the measured livestock is obtained, and the obtained distance L is fed back to the control system;

[0032] S4, according to the obtained distance L, calibrate the corresponding line 6 in the livestock data collection terminal model, and the corresponding line 6 calibrated in the same radial section is as follows Figure 4 As shown;

[0033] S5, fitting the ends of all lines in the livestock data collection terminal model into a surface, using the surface to represent the surface contour of the head of the livestock under test, and obtaining the head model of the livestock under test after selection, such as Figure 4 As shown;

[0034] S6, selecting the points to be measured in the livestock head model to be measured, and reading the corresponding dimensions. At this time, the selected parts in the livestock head model to be measured can correspond to any parts on the surface of the pig's head, so the dimensions of any parts of the pig's head can be measured, and these dimension data include but are not limited to length and circumferential dimensions corresponding to multiple parts;

[0035] S7, output the measurement results.

[0036] A data collection method using the livestock data collection terminal of this embodiment is used to collect the size data of the head of a cow or a sheep, and the steps are as shown above.

[0037] This solution solves the technical problem of the difficulty in obtaining livestock head size data, and is applicable to livestock such as pigs, cattle, sheep, and horses. It not only reduces the operational difficulty of obtaining livestock head size data, but also only requires one person to implement it smoothly, and basically does not cause injuries to operators, nor does it cause stress to the measured livestock. More importantly, it greatly improves the efficiency of obtaining livestock head size data, and can easily obtain the size data of any part of a single livestock head in a friendly measurement method within 1 to 3 minutes. In this solution, since all distance measuring sensors 3 are used to obtain data at the same time in an instant, the distance data between the two ears of the measured livestock in an active state can be measured more accurately.
