Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a measurement information processing device, and more specifically,
The present invention relates to a measurement information processing device that measures a first object to be measured and a second object to be measured related thereto, calculates both measurement results, and records and displays the measurement results and the calculation results.

For example, in order to deliver rice harvested at a farm to an agricultural cooperative, each farmer would shell, dry, and hull the harvested rice and deliver it as brown rice. The method of sampling rice to determine its grade and paying the price accordingly is still in use in most regions. However, such conventional methods have poor work efficiency and do not provide sufficient quality control of rice.

In order to improve these conventional problems, a method has been adopted in each region where communal farming facilities are established in each region and the harvested paddy is dried, stored, and hulled all at once. There is. When using this method, the problem is that the quality of the harvested paddy varies from farmer to farmer and from field to field. Therefore, as a matter of course, it is necessary to pay according to the quality, and quality control must be carried out adequately. For this purpose, it is necessary to measure the weight of paddy and brown rice after being passed through a huller, or the weight of polished brown rice and waste rice relative to paddy or brown rice, and calculate the ratio thereof.

However, performing such measurements and calculations one by one is cumbersome and prone to errors in surveying and recording.
As a result, the consistency of mechanization or automation of facilities may be compromised.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a measurement information processing apparatus that electronically performs measurement of an object to be measured and information processing of measurement results.

In the above explanation, we used rice testing as an example to clarify the problem, but similar problems should exist in many fields, not just grains like rice. Therefore, although the present invention is not limited to the case where it is used for self-inspection of rice, for convenience of explanation, the case where the device of the present invention is used as a self-inspection device for rice will be described below.

FIG. 1 is a schematic diagram showing an example of application of the device of the present invention to a self-inspection device for grains. In the case of grains as samples, especially rice, as mentioned above, in recent years voluntary verification has been carried out in some places in order to improve work efficiency and control quality. The self-inspection is carried out by sampling and accurately weighing a portion of the paddy brought in from each farmer for each delivered lot.
It is used to calculate the weight of refined brown rice (good rice) and waste rice (poor rice) that are passed through a sorter, and the percentage of the rice to the paddy, and the device used for this purpose is a self-inspection device.

In FIG. 1, a sample of paddy dried in advance is sampled, weighed as described later, and subjected to a hulling machine A. The hulling machine performs hulling twice and supplies the brown rice to the sorting machine B through the thrower A'.
Sorting machine B consists of No. 1 sorting machine A ₁ and No. 2 sorting machine A ₂ , which separate brown rice into polished brown rice and waste rice, and then weigh them through throwers A ₁ ′ and A ₂ ′, respectively. Hopper C is supplied.

The sorted refined brown rice and waste rice in the weighing hopper are sequentially supplied to the data input device 1 of the device D of the present invention. In the illustrated embodiment, the data input device 1 consists of an electronic scale, which weighs the previously sampled paddy that is sequentially supplied to the scale stand, and the refined brown rice and scrap rice that are sequentially supplied from the weighing hopper C. Converts weighing results into digital signals.

The apparatus of the present invention, including a data input device 1, is shown in block diagram form in FIG. In Figure 2,
When paddy sampled as a sample is first supplied to the data input device 1, data regarding its weight is written into the data temporary storage circuit 3 by pressing the input button 2, and the stored contents are stored in the data display circuit 4.
will be displayed.

Next, polished brown rice (or scrap rice) as a secondary sample is transferred from the weighing hopper (C in Figure 1) to the data input device 1.
When the output push button 5 is pressed, the data signal is written into the data temporary storage circuit 6. The output signal of the output push button 5 is also applied to the arithmetic program generating circuit 9, and in response to this signal, the arithmetic program generating circuit 9 generates an arithmetic command, and the data is sent to the arithmetic circuit from the data temporary storage circuits 3 and 6, respectively. 7, the ratio of secondary data to primary data, that is, the percentage of polished brown rice (or waste rice) to the importance of paddy in the embodiment, is calculated, and the calculation result is sent to the comparison circuit 11. A digital switch 12 is connected to the comparison circuit 11 to set a reference value for determining whether the calculation result is larger or smaller than a predetermined value, and the comparison circuit 11 compares this set value with the calculation result. . As a result of the comparison, if the set conditions are met, the data of the arithmetic circuit 7 is written into the arithmetic result storage circuit 10. At the same time, the data is written into the data storage circuit 8 of the data temporary storage circuit 6. The stored contents of the calculation result storage circuit 10 are displayed on the calculation result display circuit 13. In the illustrated embodiment, the weight of polished brown rice (or waste rice) is expressed as a percentage of the weight of paddy.

When data is stored in the calculation result storage circuit 10, a signal is generated and the signal is sent to the calculation program generation circuit 9. Therefore, if you now press output button 5
Even if is pressed, the arithmetic command is inhibited, while the arithmetic program generation circuit 9 sends a signal to the data output device 16. In response to this signal, data output device 1
6 is a data temporary storage circuit 3, a data storage circuit 8,
Each data is read from the calculation result storage circuit 10 and printed on recording paper.

When the data output device 16 finishes printing all the data, it generates an output signal to each data storage circuit 3,
Clear 8 and 10. Data storage circuit 8, 10
The stored data can also be cleared by pressing the reset button 14.

In the above explanation, we explained the case where after inputting paddy, inputting polished brown rice or scrap rice, but as can be seen from Figure 1, after inputting paddy, inputting polished brown rice, then inputting scraped rice, or vice versa. Three types of samples are input. How polished brown rice and waste rice are individually calculated in weight and expressed as a percentage relative to paddy will be explained in more detail with reference to FIG. 3.

Hereinafter, an embodiment in which the apparatus of the present invention is used for measuring grains for self-inspection will be further described in detail with reference to FIG.

In FIG. 3, paddy as a sample is first put on a data input device 1 which is an electronic scale. The input device 1 measures the weight of paddy and digitizes the measured value into a data signal. This data signal is applied to a comparison circuit 31 connected to the output of the input device 1 and a data latch circuit 32. A digital switch 30 is connected to the comparison circuit 31, and a minimum value to be measured is set by this digital switch. The comparison circuit 31 compares the set value of the digital switch 30 and the data signal from the input device 1,
When the data signal is larger than the set value, it is assumed that measurement is permitted and an output signal is generated, and this output signal is sent to the AND circuit 33.

Now, when input button 2 is pressed, AND circuit 33
The input command is sent to the data latch circuit 33,
Data from the input device 1 is stored in the data latch circuit 32. A data display circuit 4 is connected to this data latch circuit, and the data stored in the data latch circuit, that is, the weighing value of paddy is displayed.

Next, the refined brown rice (or scrap rice) after the paddy has been passed through a huller and a sorter is inputted into a data input device 1 consisting of an electronic scale in order to be weighed. Input device 1
The data signal digitized by the comparator circuit 61
and is sent to the data latch circuit 62. A digital switch 60 is connected to the comparison circuit 61, and the minimum metric value is set by this. The comparison circuit 61 compares the input data and the set value,
When the former is larger than the latter, an output signal is generated and sent to the 3-input AND circuit 63. The output of the NOT circuit 64 is connected to one input of this 3-input AND circuit, and a signal is applied to the 3-input AND circuit 63 when neither polished brown rice nor scrap rice is input.

Now, when the output push button 5 is pressed, the output data of the input device 1, that is, the measured value of polished brown rice, is stored in the data latch circuit 62. On the other hand, the signal from the output push button 5 is sent to the arithmetic program generation circuit 9.

The arithmetic program generation circuit 9 includes an oscillator 90 and D
The signal from the output push button 5 is applied to the D terminal of the D-type flip-flop 91. The arithmetic program generation circuit 9 is a circuit that generates pulses with different phases, and as shown in FIG. As a result, pulses such as C, D, E, and F are generated, respectively. Therefore, as shown in the figure, three two-input AND circuits 95, 96, and 97 connected to a D-type flip-flop generate phase-shifted pulse signals as shown in T, J, and R, respectively.

The output signal of the 2-input AND circuit 95 is sent as a control signal to the 3-state gate circuit 71 of the arithmetic circuit 7, and in response to this control signal, the 3-state gate circuit converts the data stored in the data latch circuit 32 into the % calculation arithmetic circuit 73. Transfer to. Also, 2 inputs
The output signal of the AND circuit 96 opens the 3-state gate circuit 72 and transfers the data stored in the data latch circuit 62 to the % calculation arithmetic circuit 72. The % calculation arithmetic circuit 73 is a 2-input AND circuit 9
In response to the control signal (fourth diagram) from 7, the data from the data latch circuit 32, that is, the data from the data latch circuit 62 attached to the weight value of paddy, and the percentage of the weight value of ready-milled brown rice (or waste rice) are calculated. It calculates and sends the calculation result to the comparator 110.

A digital switch 12 is connected to the comparator 110, which sets a reference value for sorting refined brown rice and waste rice. Therefore, the comparator 110 compares the set value set by the digital switch 12 with the calculation result from the % calculation calculation circuit 73, and sends a signal to the 2-input AND circuit 111 when the calculation result is larger than the set value. , on the other hand, when the calculation result is smaller than the set value, a signal is sent to the two-input AND circuit 112.

Since a signal is applied to the 2-input AND circuits 111 and 112 from the AND circuit 97 of the arithmetic program generation circuit 9 at this time, the output signal from the comparator 110 causes the 2-input AND circuits 111 and 112 to
Therefore, the arithmetic circuit 7 for calculating the percentage
The result of operation No. 3 is written into either latch circuit 100 or 102. In other words, if it is polished brown rice, there are 2 inputs.
The AND circuit 111 operates and data (percentage of refined brown rice) is written to the latch circuit 100. On the other hand, if it is scrap rice, the two-input AND circuit 112
operates to write data (percentage of waste rice) into the latch circuit 102. At the same time, 2
Since the output signal of the input AND circuit 111 is applied to the latch circuit 81 of the data storage circuit, the latch circuit 81 operates the data latch circuit 6 in response to the signal.
From 2, write the data, that is, the weight value of polished brown rice.
Similarly, the output signal of the two-input AND circuit 112 writes data to the latch circuit 82, that is, the numerical value of the weight of waste rice.

Therefore, in the case of polished brown rice that exceeds the set value set by the digital switch 12, its weight value is written to the latch circuit 81, its percentage to the paddy is written to the latch circuit 100, and the percentage value display circuit 13 is written.
A percentage is displayed at 0. On the other hand, in the case of waste rice, its weight is sent to the latch circuit 82, and its percentage to the paddy is sent to the latch circuit 102.
, and the percentage is displayed on the % numerical display circuit 131.

A data detection circuit 101 detects that the percentage of refined brown rice has been written to the latch circuit 100, and a data detection circuit 103 detects that the percentage of waste rice has been written to the latch circuit 102. When both data detection circuits 101 and 103 detect data, that is, when polished brown rice and scrap rice are respectively applied to the electronic scale 1, the two-input AND circuit 98 operates and prohibits the data latch circuit 62 from receiving the data. , all D of the arithmetic program generation circuit
Resets the type flip-flops 91, 92, 93, and 94.

Next, when output pushbutton 5 is pressed, 2-input AND circuit 9
9 operates to generate a print command on its output. In response to this print command, the printer drive circuit 16 drives a printer (not shown) to print out data on printing paper through various latch circuits. That is, the data latch circuit 32 prints out the weight of paddy, the latch circuits 81 and 82 print out the weights of polished brown rice and scrap rice, respectively, and the latch circuits 100 and 102 print out the percentages of polished brown rice and scrap rice to brown rice, respectively.

When printing is completed, a print end signal is generated from the printer drive circuit 16, which clears the data latch circuit 32 and clears all other latch circuits 81, 82, 10 through the OR circuit 15.
Clear 0,102. Incidentally, a reset push button 14 is connected to the other input of the OR circuit 15, so that the latch circuit can be cleared independently.

As described above, according to the present invention, even if an arbitrary amount of sample is input, the contents of the sample are verified and the verification results are automatically recorded, which improves work efficiency and eliminates transcription and calculation errors. As a result, the reliability of the test is improved.
