Referring to Figure 1, an embodiment of a method of measuring body weight according to the present invention is presented, the method comprising the steps of:

S11. Detect whether livestock passes through the scale. When there is a livestock passing the scale, the process proceeds to the next step S12.

In the embodiment of the present invention, an electronic tag is attached to each animal, and the electronic tag can be scanned by the reader. When the electronic tag is scanned, it is determined that the animal passes through the scale. The electronic tag, also known as the RFID (Radio Frequency Identification) tag, is preferably a passive RFID tag, which is required to be waterproof, corrosion resistant, and not easily damaged. In order to improve the accuracy of the judgment, the validity of the scanned electronic label can be judged, and when the valid electronic label is scanned (for example, when the specific identification code is scanned, the electronic label is determined to be valid), then the livestock is determined. After the scales.

As shown in FIG. 2, the scale scale 230 can be installed at the exit of the culture shed 100. The end of the scale scale 230 near the culture shed 100 is the entry end, and the end away from the culture shed 100 is the outlet end. The scales 230 have a length and width similar to that of an adult animal, preventing the two animals from simultaneously squeezing the scale 230. The bottom of the weighbridge 230 can be reinforced with concrete to ensure that it will not settle. It is recommended to be installed in the shelter to prevent flooding. The scales 230 can establish a communication connection with a server or terminal device, such as a mobile communication system such as 2G, 3G, 4G, 5G, etc., to connect to the server.

The reader can be placed on the side of the scale 230 (i.e., the fence 110) or in the middle, corresponding to the electronic tag on the animal. As shown in FIG. 2, in the embodiment of the present invention, two readers are disposed on opposite sides of the scale scale 230, which are a first reader 210 and a second reader 220, respectively, and the electronic label is disposed on one side of the livestock. Preferably, it is attached to the front leg (such as the front hoof) or the backward (such as the hoof) of the livestock, and the maximum distance between the first reader 210 and the second reader 220 for detecting the electronic tag is preferably limited to 30-40 cm, so that the livestock When passing the weighbridge, only one side of the reader can scan the electronic tag, so that it can distinguish whether the animal is slaughtered or entered, and then measure the weight of the animal when it is released and the weight when entering the bar.

For example, assuming that the electronic tag is affixed to the left side of the animal, when the first reader 210 scans the electronic tag, the livestock is entered, and the measured body weight is the weight of the entry; when the second reader 220 scans the electronic When the label is used, it indicates that the livestock is out of the bar, and the measured body weight is the slaughter weight. Conversely, when the electronic label is attached to the right side of the animal, it is just the opposite.

Further, the first reader 210 can be disposed near the entrance end of the scale 230, such as the distance between the first reader 210 and the entrance end is 20%-40% of the total length of the side of the scale 230, preferably 1 /3; The second reader 220 is disposed at a position close to the exit end, such as the distance between the second reader 220 and the exit end is 20% - 40%, preferably 1/3 of the total length of the side of the scale 230. At this point, it is assumed that the electronic tag is attached to the left forefoot of the animal. When the animal enters the bar, the first reader 210 will detect the electronic tag. At this time, the limbs of the animal are already above the scale 230, and the measured weight is the whole of the livestock. Weight, the accurate weight of the entry is measured; when the animal is out, the second reader 220 will detect the electronic tag. At this time, the limbs of the animal are also above the scale 230, and the measured weight is the total weight of the animal. Accurate slaughter weight.

In addition, the electronic tag can also be placed on other body parts of the animal. Taking livestock as a cow, for example, the electronic label can be attached to the horn of the cow. At this time, the position and height of the reader should be adjusted accordingly. When the cow passes the scale 230, the distance between the electronic tag and the reader is within a certain range. Within the range, because the height of the horns is different and there are different states of head and head, the difficulty of implementation is greater than that of the electronic label attached to the hoof.

It can be understood by those skilled in the art that the detection of the electronic tag by the reader can be performed by other sensors, such as an infrared sensor, a laser sensor, etc., which is not limited by the present invention.

S12. Read the data of the electronic tag on the animal through the reader as the identification information of the livestock, and measure the weight of the animal through the scale.

The electronic tag contains the unique identification information of the animal, and the reader reads the data of the electronic tag on the animal to obtain the identification information of the animal, and the identification information can identify the identity of the animal.

In order to save electric energy, in the embodiment of the present invention, when the livestock is detected to pass the scale, the scale is started, and the weight of the livestock is measured by the scale, and when the animal does not pass the scale within the preset time after the weight measurement is completed, the scale is closed. Weighbridges, which prevent the scales from being turned on for a long time while idle, wasting power. The opening and closing scales described herein can be power to the ground scale (or weighbridge load cell), or to wake and sleep scales (or weighbridge load cells).

In the embodiment of the present invention, in consideration of the fact that the livestock passes through the scale, the measured reading may be shaken. In order to improve the accuracy of the measurement, when the weight is measured, the weight is measured by the scale every preset length, and the measurement is continuously at least N. (N ≥ 4) times, then the maximum and minimum values are removed from the measured values, and the average of the remaining measured values is obtained as the weight of the livestock. The aforementioned preset duration, that is, the interval of continuous measurement, is preferably set to 40-60 milliseconds. For example, the weight is measured every 50 milliseconds, measured continuously 4 times, the maximum value and the minimum value are removed, and the average of the remaining two values is obtained as the weight of the livestock.

Further, in order to further improve the accuracy of the measurement, before the continuous measurement, the weight can be detected by the scale to determine whether the weight is within a preset range, and when the range is within the preset range, the scale is measured once every preset time. Weight and continuous measurement multiple times. The aforementioned preset range, that is, the preset weight range, can be set according to the actual weight of the reared livestock.

In other embodiments, it is also possible to directly average at least two weight values measured continuously, using the average as the weight of the animal. The specific measurement method of the body weight of the present invention is not limited.

S13. Sending identification information and weight of the livestock to the outside.

In the embodiment of the present invention, the identification information and the weight of the livestock are sent to the server, and the server stores the information according to the identification information, the weight and the time information of the livestock, so as to facilitate the post-analysis and processing of the health and diet of the livestock. When there are two readers, the weight is subdivided into the weight of the entry and the weight of the stall. The server classifies the two weights.

In other embodiments, the identification information and the weight of the animal may be transmitted to the terminal device, such as a mobile terminal, such as a mobile phone or a tablet.

The method for measuring body weight according to the embodiment of the present invention can be applied to a livestock farm for raising livestock such as cattle, horses, sheep, and donkeys, and a weight measuring system is installed at the exit of the breeding shed of the livestock farm to automatically measure the weight of the reared livestock.

As shown in FIG. 3, an example of a weight measuring system for implementing the weight measuring method of the present invention includes a weighbridge load cell, a filter amplification and analog to digital converter, a first reader, a second reader, and a communication unit. (including microprocessor, can include one or more communication modes in 2G/3G/4G/5G), peripheral display and interface unit, and battery and power management unit. The load cell converts the measured weight into an analog electrical signal, which is processed by the filter amplification and analog-to-digital converter into a digital signal, and converted into a body weight value by the range of the microprocessor of the communication unit; the first reader and the second reader The electronic tag is read when the livestock enters and exits the bar; the communication unit acts as the master to receive the identification information of the livestock output by the first reader and the second reader, and drives the peripheral display and the interface unit to output the identification information and weight of the livestock. At the same time, the above information is transmitted to the server through the 2G/3G/4G/5G network. In order to save power, only when the first reader and the second reader read a valid electronic tag, the microprocessor of the communication unit turns on the power of the load cell for weighing, and the battery and power management unit are unit circuits. Provide power.

In the weight measuring method of the embodiment of the present invention, when the livestock passes through the scale, the data of the electronic tag on the animal is read by the reader as the identification information of the livestock, the weight of the animal is measured by the scale, and the identification of the animal is sent out. The information and weight make it possible to automatically measure the weight of the animal without manual measurement and recording, which greatly improves the measurement efficiency and accuracy of the animal's weight.

Referring to Figure 4, a first embodiment of the weight measuring device of the present invention is proposed. The device comprises a detecting module 10, a reading module 20, a weighing module 30 and a transmitting module 40, wherein: the detecting module 10 is arranged to detect whether there is a livestock After the scale; the reading module 20 is configured to read the data of the electronic tag on the animal through the reader when the animal passes the scale, and use the data as the identification information of the livestock; the weighing module 30 is set to have livestock When passing the scale, the weight of the animal is measured by a scale; the sending module 40 is arranged to send the identification information and weight of the animal outward.

In the embodiment of the present invention, an electronic tag is attached to each animal, and the detecting module 10 includes a scanning unit 11 and a determining unit 12 as shown in FIG. 5, wherein: the scanning unit 11 is configured to control the reader to scan the electronic tag; The unit 12 is arranged to determine that the animal has passed the scale when scanning the electronic tag.

In order to improve the accuracy of the judgment, the determining unit 12 can also judge the validity of the scanned electronic label, and when the valid electronic label is scanned (for example, when the specific identification code is scanned, the electronic label is determined to be valid), Only then is it determined that the animals have passed the scale.

As shown in FIG. 2, the scale scale 230 can be installed at the exit of the culture shed 100. The end of the scale scale 230 near the culture shed 100 is the entry end, and the end away from the culture shed 100 is the outlet end. The scales 230 have a length and width similar to that of an adult animal, avoiding the simultaneous loading of the two animals on the scale 230.

The reader can be placed on the side or middle of the scale 230, corresponding to the electronic tag on the animal. As shown in FIG. 2, in the embodiment of the present invention, two readers are disposed on opposite sides of the scale scale 230, which are a first reader 210 and a second reader 220, respectively, and the electronic label is disposed on one side of the livestock. Preferably, it is attached to the front leg (such as the front hoof) or the backward (such as the hoof) of the livestock, and the maximum distance between the first reader 210 and the second reader 220 for detecting the electronic tag is preferably limited to 30-40 cm, so that the livestock When passing the weighbridge, only one side of the reader can scan the electronic tag, so that it can distinguish whether the animal is slaughtered or entered, and then measure the weight of the animal when it is released and the weight when entering the bar.

For example, assuming that the electronic tag is attached to the left side of the animal, when the first reader 210 scans the electronic tag, the detecting module 10 determines that the animal is in the bar, and the measured body weight is the weight of the bar; when the second reader 220 When scanning the electronic tag, the detecting module 10 determines that the animal is out of the bar, and the measured body weight is the slaughter weight. Conversely, when the electronic label is attached to the right side of the animal, it is just the opposite.

In addition, the electronic tag can also be placed on other body parts of the animal. Taking livestock as a cow, for example, the electronic label can be attached to the horn of the cow. At this time, the position and height of the reader should be adjusted accordingly. When the cow passes the scale, the distance between the electronic tag and the reader is within a certain range. Inside, due to the difference in height of the horns and the different states of head and head, the difficulty of implementation is greater than that of the electronic label attached to the hoof.

The aforementioned preset duration, that is, the interval of continuous measurement, is preferably set to 40-60 milliseconds. If the measuring unit 31 measures the weight every 50 milliseconds and continuously measures 4 times, the calculating unit 32 removes the maximum value and the minimum value, and finds the average of the remaining two values as the weight of the livestock.

As shown in FIG. 7, in order to further improve the accuracy of the measurement, in other embodiments, the weighing module 30 further includes an analysis unit 33, which is configured to detect whether the weight is within a preset range by the scale When it is within the preset range, the notification measuring unit 31 measures the weight by the floor scale every preset length of time. The aforementioned preset range, that is, the preset weight range, can be set according to the actual weight of the reared livestock.

In other embodiments, the weighing module 30 can also directly average the continuously measured at least two weight values, using the average as the weight of the animal. The specific measurement method of the body weight of the present invention is not limited.

In the embodiment of the present invention, the sending module 40 sends the identification information and the weight of the livestock to the server, and the server performs classified storage according to the identification information, weight and time information of the livestock, so as to perform post-analysis processing on the health and diet of the livestock.
