重を測定するための方法に関する。Detailed Description of the Invention The present invention uses a weight measuring device that detects the weight of chickens as an electrical signal and displays the measured value digitally, without taking the chickens out of the cage. Concerning a method for measuring body weight.

。Conventionally, the weight of chickens raised in chicken cages was measured by taking the chicken out of the cage, tying its legs and keeping its wings still so that it would not move wildly, and determining rpJJ using a scale. be. Therefore, the measurement work is extremely complicated and inefficient. To overcome this drawback, it would be best to measure the weight of the chickens while they are in the cage.
If a weight measuring device is inserted into a cage, the chickens will become violent, and the weight reading will keep changing and become unstable, making it impossible to read the measured value under such conditions.
本発明はこのような事情に鑑みて開発されたもので、鶏

。The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a measuring method that can accurately measure the weight of a chicken while it is in a cage.

ある。A feature of the present invention is that a weight measuring device that detects the weight as an electrical signal and displays the measured value digitally is used, and when the weight measuring device is inserted into a cage and the weight of the chicken is measured, the weight of the chicken is measured. Even if the weight indication value continues to change wildly, it will reach a stable state in a short period of time, and even if it is impossible to read the stable state with the naked eye, it can be detected electrically. Since it is possible to detect the maximum value and the minimum value of the electric signal, a stable state is defined as a state in which the difference between the maximum value and the minimum value is within 3% of the maximum value for 0.5 seconds or more. A predetermined value within a range of change in a stable state including the value is digitally displayed as a measured value.

からである。In the present invention, as described above, the state in which the difference between the maximum value of the electrical signal and the /11 value is within 3% of the maximum value is 0.
The reason why we decided to display the measured value when it lasted for more than 5 seconds was because we repeatedly conducted experiments to compare and contrast the measured value with the conventional weight measurement method under various conditions. This is because it was not possible to accurately measure the weight, and an accurate measurement value could only be obtained when the weight was set within the multi-value range.
以下、本発明の好適な実施例を添付図面に基づいて詳細
に説明する。Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

容範囲及びその持続時間の設定を行なうことができる。First, a weight measuring device used in carrying out the present invention will be explained based on FIGS. 1 to 4. The scale 1, which is a weight measuring device, is equipped with a known electrical internal mechanism using four load cells 3 for 1 kg mounted on a bridge 4514 of the scale base 2. When a chicken 4 rides on the scale 2, the average load on the four load cells 3 assembled on the bridge, that is, the weight of the chicken 4, is an electrical signal (voltage value) even if the part on which it sits is not in the center of the scale 2. Detected as . The voltage waveform outputted from the body weight detecting section 5 made up of each of the load cells 3 is sent to an amplifying section 6 made up of an operational amplifier, where it is amplified, and then sent to a stable state detecting section 7 . This stable state detection section 7 includes a variable capacitor (not shown) and a variable resistor (not shown), and by changing the capacitance value and resistance value of these, the maximum value of the voltage waveform to be detected can be determined. You can set the allowable range of the difference between and the minimum value and its duration.

The voltage value sent from the amplifier section 6 is converted into a digital signal as a measurement value, converted into a BCD code signal, and then output. The BCD code signal is input to a display section 10 consisting of a wasegged LED display 9 equipped with a driver connected to a flip-flop circuit, and the LED display 9 receives the above-mentioned measured value by the signal holding function of the flip-flop circuit. Continues to display digitally until reset.

２は水平に維持されるものである。The LED display 9 is formed to protrude upward from one side of the scale 1, and is provided on the upper surface of the one protruding portion. The bottom surface 11 of the scale 1 is formed to match the slope of the floor surface 13 of the cage 12, and when the scale 1 is inserted into the cage 12 and the bottom surface 11 is brought into contact with the floor surface 13, the scale base 2 It is kept horizontal.

。Next, a method of measuring the weight of the chicken 4 in the cage 12 using the scale 1 described above will be explained. First, the stable state detection unit 7 is adjusted to set the allowable range of the difference between the maximum value and the minimum value of the voltage waveform to 3% of the maximum value, and the duration thereof to 1 second. Note that the duration may be 0.5 seconds or more, but if a more accurate weight value is desired to be measured, it is desirable to set this to at least 1 second.

Further, although the above-mentioned adjustment may be performed each time the weight is measured, it is set in advance to a predetermined value as described above, and the weight i! is repeated at this predetermined value! ! I-determination may also be performed. Next, when the scale 1 is inserted into the cage 12 from the direction of the feeding gutter, @4 in the cage 12 is forced to ride on the scale stand 2 of the scale 1. At this time, since the scale 2 is formed to be inclined so that the bottom surface 11 coincides with the floor surface 13, it is maintained horizontally, and the weight of the chicken 4 can be measured.

されるまで続くものである。Since the chicken 4 is violently moving on the scale 2, the voltage waveform outputted from the weight detecting section 5 has a large change as shown in FIG. Here, as shown in the water section shown by arrow A in FIG. 5, which is shown in FIG. If this continues for more than a second, the stable state detection section 7 detects this state and outputs a detection signal. The voltage value at this point passes through the Δ/D converter 8 and is digitally displayed as a measured value on the LED display 9, and this display continues until it is reset.

ることができる。As is clear from the above explanation, according to the present invention, when the difference between the maximum value and the minimum value of the electrical signal continues for 0.5 seconds or more, the maximum value and the minimum value A predetermined value within the thinning range, including both values, is digitally displayed as the measured weight value, so it is possible to measure the weight by capturing the short resting state of the chicken when it is violent in the cage, and it is possible to measure the weight while the chicken is in the cage. You can measure your weight easily and accurately, and the measured values can be easily read.
