【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、乾燥機における穀粒水分検出方法に関す
る。TECHNICAL FIELD The present invention relates to a method for detecting grain moisture in a dryer.

は未熟粒としてカット処理される形態が常套である。[Problems to be Solved by the Prior Art and Invention] The moisture content of a grain during drying is obtained by obtaining a predetermined number of data with a moisture detection sensor, and these are averaged and displayed, or used for grain drying control. The permissible range (threshold value) for obtaining the number is set to a fixed value, and those exceeding this range are usually cut as immature grains.
ところが、乾燥機内の穀粒は、ばらつきがありカット処

込まれ難くなるため正確な水分値が算出されない。However, if the grains in the dryer have variations and the range to be cut is fixed, it is difficult to capture the necessary data, and the accurate moisture value cannot be calculated.

穀粒水分検出方法の構成とする。The present invention is intended to solve the above-mentioned drawbacks, and in a grain drying device provided with a moisture sensor 1 to calculate an average value Mn of a predetermined number m, the average moisture value related to the previous measurement is used as the reference dry moisture of the present measurement. The reference moisture content value is added to the reference allowable moisture value E to set it as an allowable range, and the detected moisture value exceeding this allowable range is cut, and a predetermined number m of detection data is taken in, and the moisture value of the present measurement is taken. It is configured to calculate Mn, and the allowable value E is set to a plurality of different values α and β, which is a configuration of a grain moisture detecting method in a dryer.

定精度を向上するものである。First, it is determined whether or not the detection data from the moisture sensor 1 is within an allowable range in which the allowable value is added to the reference dry moisture value. The data exceeding this range is cut, and when the number of data within the range reaches the predetermined number m, the average value Mn is calculated based on the data of the predetermined number M. The average value is calculated for those which are set, that is, the permissible range is set to be wide and narrow, and the number of data corresponding to them is set in advance. Therefore, the data acquisition range fluctuates while responding to the water distribution depending on the magnitude of the variation, and the accidental cutting process is less likely to occur, thus improving the measurement accuracy.

るものである。Further, the CPU 32 stores the reference dry moisture value Ms n-1 . This reference dry moisture value Ms n-1 affects the data removal for the next moisture measurement and average value calculation, and is equal to, for example, the average moisture value at the measurement signal output (n-1) th time, that is, Mn-1. This is used as a reference for moisture detection and average value calculation of the n-th detection number m. That is, when the measurement signal is received, the moisture sensor 1 repeats the moisture detection of the grains, the measurement of which is sequentially performed. The moisture sensor 1 has detection values Mn 1 and Mn 2
This range is determined while judging for each of the above-mentioned reference dry water values Ms n-1 within the range (Mn-1 ± α) of the preset allowable value E (= α, β, α <β). The inside is used for the average value calculation, and when it exceeds this range, the cutting process should be performed, and when the number reaches the detection number m within the range, the average value Mn is calculated.

れらを元に平均値算出を行なうものである。Further, this average water content value Mn is used as the next dry water content value. That is, the detected moisture value in the range of Mn ± α is taken in and becomes the target of the average value calculation, but the allowable value E is set to be in the range of β, and the first range of Mn ± α is set. Alternatively, it can be set in two steps in the second range of Mn ± β. Among them, when the predetermined detection number cannot be obtained within the first range and the predetermined detection number is obtained within the second range as described above, the detection data in this range is used as the average value Mn + 1. When the predetermined number is within the first narrow allowable value (E = α), the water content average value is calculated as it is, but the number of cut processing is large and the second wide allowable value (E = β).
Is prepared, and when a predetermined number is obtained within this range, the average value is calculated based on these.
以上、水分ばらつきに応じて水分平均値算出のデータ取
り込み許容範囲が異なることとなるから、無闇にデータ
カット処理が行なわれず、算出値の精度が向上する。As described above, since the data fetching allowable range of the water content average value is different depending on the water content variation, the data cutting process is not performed unnecessarily, and the accuracy of the calculated value is improved.

容範囲に必要な所定回数の水分検出回数を得たときは、
これを基準に水分算出される場合もある。It is assumed that the previous average water content value Mn-1 was 22%. A drive output rises to the moisture sensor 1 for the present average moisture calculation Mn, and moisture detection is performed. At this time, a preset allowable value, that is, 1.0% (= α) is added to the average moisture value. It is monitored whether or not it falls within the range of 22% ± 1.0%, which is the value, and while the other parts are cut, those within this range are sequentially taken in as Mn 1 , Mn 2 , Mn 3 ... When they reach the preset number of times, they are averaged based on them. In this way, the average moisture value Mn is calculated. It is assumed that Mn = 21.8%. Here, in addition to the value for the first range setting, the allowable value is a larger allowable value (for example, 1.5).
% (= Β) is set in the CPU, and when the predetermined number of times of moisture detection necessary for the second allowable range is obtained,
The water content may be calculated based on this.

にの平均値を算出して平均水分値Mn+1とする。Next, the average water content value Mn = 21.8% is used as a reference dry water content value, and the next water content measurement is performed. In other words, 21.8%
= 1.0% and 21.8% ± 1.5% are used as the first and second allowable ranges, but data is taken in, but in the measurement, the second set allowable range is 21.8% ± 1.
The number of data in 5% is obtained first, and the average value of each of the data is calculated to be the average water content Mn + 1.

る。In addition, when the burner 12 is activated and output by the operation device 5 and the rotation interlocking relation of each part is output, hot air is generated to dry the grain. Thus, when the preset target moisture value is reached while being circulated and dried, the automatic stop signal is output.
その間は所定時間間隔おきに、水分検出信号が出力され
