9 is a flowchart illustrating a process of obtaining a peak value and a moving average value of the peak value for measuring the highest value generated when the grain is crushed by the present invention, which is obtained from the grain auger 6 described above. At the moment of receiving the transferred grain and supplying it to the granules, the change of electrical resistance is detected and converted into water at the moment of breaking, and at this time, the amount of grain is broken in order to improve the accuracy of accurately and stably measuring the moisture of the grain. The peak value for measuring the highest value among the grain moisture signals of and the moving average value of the peak value are detected.

In this case, the peak value is detected by converting the electrical signal into an A / D value and binarizing it, and then using the converted A / D value, the current A / D value (TC) and the past (previous) A / D value. The current A / D value TC, which is the TO and the difference value TmpD, is obtained by subtracting the past A / D value TO from the TmpD = TC-TO.

A / D value TO at the time when the past value TD which is the previous value of the difference value TmpD is greater than 0 (TD> 0) and the difference value TmpD is less than 0 (TmpD <0) When the peak value is finally confirmed, it is stored in the storage output terminal OVC, and the peak value stored in the storage output terminal OVC is the maximum moisture A / D value M_MAX and the minimum moisture A / D value M_MIN. Each will be compared.

That is, the peak value stored in the storage output terminal OVC is greater than the maximum moisture A / D value M_MAX (OVC> M_MAX), or the peak value stored in the storage output terminal OVC is the minimum moisture A / D value M_MIN. If (OVC <M_MIN) is smaller than), the storage output terminal (OVC) becomes '0' and then the number of peaks is counted (PC).

The moving average value is detected using the detected peak value. At this time, the peak value detected and identified is sequentially stored in the storage buffer PB, and the peak value stored in the storage buffer PB is buffered. By dividing by the number, the current moving average value is obtained and detected.

The value obtained by subtracting the threshold value 100, which is a threshold value that has been set in advance by the laboratory test and is set in comparison with the current peak value, is greater than the current peak value and is stored in the OutValueCurr. The current peak value is stored, and if the subtracted value is less than or equal to the current peak value, it is stored only in the storage buffer PB and is reflected only in the moving average.

The calculated moving average value is converted into grain moisture by a moisture conversion regression equation inputted to the electronic circuit unit 24, and the converted moisture value is sent to the data calculating unit 60 to calculate grain yield. Will be provided.

Using the measurement principle of the grain moisture measurement sensor unit 20, the indoor test and the packaging test were carried out. As a result, the crystal coefficient was about 1 in the indoor test, and the crystal coefficient in the packaging test. It is confirmed that the water measurement carried out by the present invention is precisely measured by the result that the value of about 0.54 is lower than the expected value, but about 0.54 is obtained (see FIG. 10).

On the basis of this, when examining the yield, by obtaining the quantity information and moisture information of the grain at the harvest stage, it is possible to determine the yield productivity of the packaging, and also to provide the yield information quickly and accurately necessary for precision agriculture. As a result, the efficiency of pavement management is increased, and the next year's pavement management plan can be developed based on this information, thereby enabling eco-friendly precision agriculture.

As described above, the present invention is to improve the efficiency and convenience of the yield survey through the real-time measurement technology, and to improve the screening performance of the jabal-type combine by the easy acquisition of grain information and moisture information at the harvest stage The effect of setting effective drying method in the common drying facility and the effect of judging the productivity of the quantity of the package can be used to match the surrounding advanced IT technology to agricultural machinery by providing prompt and accurate information on the yield of crops essential for precision agriculture as a whole. This can bring about multiple effects such as the creation of added value of agricultural machinery and the transition from simple working machinery to informational agricultural machinery.
