Abstract

PURPOSE:To shorten the time necessary for the setting of a standard time by adding the function of a standard value generating circuit to the operation of a counting circuit. CONSTITUTION:The standard value generating circuit 5 outputs a set signal, which is sent to a controlled system 2 through the counting circuit 1. The controlled system 2 sends a corresponding output to a comparative decision circuit 3, which decides on whether the output is larger than a refernece value or not and sends the result to a pulse generating circuit 4. This pulse generating circuit 4 sends a count-up or -down pulse to the standard value generating circuit 5 according to the decision result, and when the reference value is equal to the output of the controlled system 2, the comparative decision circuit 3 sends a coincidence signal to the standard value generating circuit 5. The circuit 5 sends the set signal to the counting circuit 1 until the coincidence signal is obtained to vary the reference value continuously and also stops the variation on receiving the coincidence signal. This operation is carried out repeatedly in sequence from the largest weight and the counting circuit 1 is put in normal operation when the output of the controlled system 2 becomes equal to the reference value.

Description

[Detailed description of the invention] [Technical field of light example] This invention relates to a control device including a counting step as a component. The one shown in Figure 1 was rare.

The pulse generation circuit (4) outputs a number 1 which can distinguish between wrinkles and wrinkles, and the pulse generation circuit (4) outputs a pulse for count-up, a pulse for count-up, and a pulse for kakuntodakun from the comparison/discrimination circuit (31). 11.

In the case where the output from the controlled object (2) is equal to the output from Taifu 1, the pulse generating circuit (4) does not generate a pulse for cacundo. Counting times +11 is pulse generation time II! It counts up or down in response to the pulse ridge τ and the 7 pulses sent from Hi control is performed so that direct and 1≠shi.

Traditional accounting time lol! 1 performs the above operation, so if you set it to a certain known initial value, the nearby 5

Although it is a market only in the vicinity of B, the moving platform whose first shift is the main river counts up from one initial pumped drop, and this counts up and slows down to the first shift of that leg. Until then, a large number of counting pulses were generated and anastomoses had occurred, which of course had the disadvantage of increasing the number of pulses required.

[Original side overview]

This completeness was made because of the drawbacks of the above-mentioned Takumihon (Clbo 7D), and instead of 1 prefecture, the IIIJ condition for H1 wholesale was changed to λ. ) In the vicinity of J, which is called standard 1 time less than c per day, there is 1 in the lIl control vs. urine.
It is an object of the present invention to provide a measurement circuit r that can be used with one pulse ridge more than one white main ridge output of a 61-number circuit.

[Heavenly example of the first son] Hereinafter, 16 hM on this original side will be exemplified as ωt in the figure.

In Fig. 2, )l) is the counting circuit, (2) is the controlled object controlled by the output from the calculation circuit +l+, and (3j is the controlled object (the output τ of the control result from 21 1
A comparison 'l'lJni circuit that outputs the result of adding one step size, (
4) is a pulse generation circuit that generates a count-up or count-down pulse according to the output from the comparison/discrimination circuit (3); (5) is a pulse generation circuit that generates a count-up or count-down pulse according to the output from the comparison/discrimination circuit (3); C that generates a $ value;! , is a quasi-value generation circuit.

Next, the operation will be described. When the bd number indicating that the ;te control condition of the iti control target has changed to the father, #,
The key value setting circuit (5) is in a state of operation, and
13j Send to the number circuit ill, set the initial value in the MV of the metering circuit Illμ, and output from the standard value solo generation circuit (output the N as an output signal as it is. What will happen?

Below, the number 7 of the 11J single unit on the glare side, congratulations (7), is limited to those in which the counting circuit sends out a binary 8-bit output, and l means 9.0. No. 16 means a state of affairs, and the output is expressed in binary numbers.No change, standard value generation circuit 1
611i10000000 is output and sent to the counting circuit (1), and immediately the counting circuit fi+ outputs 10000000.
Sends the output to the controlled object (21. Controlled object +21
The output corresponding to this output is output to the comparative soft judgment circuit (3), and the comparison judgment circuit (3) determines whether the output from the controlled object (2) is larger, smaller, or harsher than the reference value. Barsno output according to? = Send to year circuit (4). The first pulse generation circuit (4) sends out a count-up pulse or a count-down pulse to the total standard value generation circuit (5) according to the output from the comparison cycle Wrt31. When the output from the base 1$1 old and ili controlled object (2) is bad, no pulse for counting is generated. Further, the ratio soft discrimination circuit (3) sends coincidence No. 16 to the standard value generation circuit (5) when the extinction value and the output from the controlled object (2) are equal.

At 1, which receives the coincidence information from the comparison/discrimination circuit (3), the standard value generation circuit 15) sends a setting signal to the counting circuit +11, and the counting circuit ill receives the output of the standard-generation circuit 15) as it is. The output is the controlled object (sent to 21, standard 1m1
For the generation circuit (U), continue to use the standard value. Then, by the ratio soft discrimination circuit + 31 sword/ra coincidence No. 11 τ father 1 d Q, the standard $- value generation circuit 51 completely stops sending out the Z fixed ro No. 0 counting circuit (1) is 9, count up pulses or count down pulses from the pulse generator circuit (4), and
1 direct original raw circuit tt+I has stopped the standard 1 page history and is 1000
0000's first Jν] The state of the blade I and II).

Pulse 9B Regeneration 1 (4) The count-up pulse is sent out. In other words,
The output state j up to /+ is set to 1, and the output of the city is also set to 5 and output with a large rule C for θ(.

Countdown pulses such as 10+417Jj and others were issued for the opposite 1ko, the pulse former king, and the closing was 4i = bile e
The king circuit +51 is 01000000τ output car'j-i. In other words, IM where the countdown pulse is output from J5:
Add lτIfl to 1jiJ and set it as the output of 7, and set the output of 4 to the output of 4, (output as i 0. Finally, the ratio discrimination circuit (3) outputs id8 indicating that the output of the controlled object +21 has become equal to the reference value, and the counting circuit 11.1 performs the normal operation. Naturally, the output of the counting circuit Il+ in the Kakuto operation state should maintain the output 4 range necessary to control the controlled object (2), so as is clear from the above operation, the output of the counting circuit Il+ is 8. The operation will be completed within the number of pulses.

This is an anastomosis based on the operation shown in Figure 1, and the initial value is 10000.
Assuming that the operation completion is 11000000 as 000, 64 pulses are required. It is clear that the number of output pits increases as the number of output pits increases. The above example assumes a counting circuit with an 8-bit output for simplicity. is strongly related to the number of output bits.

In the above example, the count-up pulses and count-up pulses are sent from the pulse generation circuit, but as shown in Figure 8, the counting circuit uses the results of the comparison and discrimination circuit. Okay, count up the input pulses.

It is also possible to use a counting circuit that causes a count-up or no count-down, and a pulse generator circuit that continues to send out pulses for each step. As shown in Figure 4, depending on the 4 types of objects to be controlled, digital-analog)
The operation remains the same even if the converter (6) is added.

〔Effect of the invention〕

As described above, according to the present invention, since the performance of the standard generator circuit described above is added to the operation of the normal counting circuit, it is possible to open the t-smoke when necessary until setting the semi-value of the target Nobu. It has the effect of embroidery.
