本発明は、グランドの名状atの調整制御における目標
値設定操作あるいは調整操作を行うに好適な関数型調整
設定器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a function-type adjustment setting device suitable for performing a target value setting operation or an adjustment operation in adjustment control of a ground name AT.
一般に、プラント状態量の設定操作に関しては、追従性
を考慮して現状の値から漸次増加ないし減少させる設定
法をとることが多い。Generally, when setting plant state quantities, a setting method is often used in which the plant state quantities are gradually increased or decreased from the current value, taking followability into account.
従来、このような設定には第1図に示すような調整設定
4装置が一般に用いられている。この図で1は増減操作

ェース回路2を介して電動機3が正転あるいは逆転動作
を行い、プラントの弁等の開度t−変える。Conventionally, an adjustment setting device 4 as shown in FIG. 1 has been generally used for such settings. In this figure, 1 is an operation switch that performs increase/decrease operations, 2 is an interface circuit that issues forward/reverse rotation commands, 3 is an electric motor that operates such as a Fi arm, 4 is an opening detector that increases/decreases paYr by the electric motor 3, and 5 is an opening degree. In this adjustment setting device, which is a display instrument, when the operation switch 1 for increase or decrease in Fi is closed, the motor 3 rotates forward or reverse via the interface circuit 2, and the opening of the plant valve etc. t-change.
この弁等の開度を開度検出器4が検出して開度表示計器
5Ki1度を表示する。fランド運転員が開腹表示計器
5の指示値を確認しながら操作管継続し、弁度の開腹が
所望の値になったときに操作スイッチの操作を停止する

、第2図のグラフに示すように、設定値は操作時間に対
し連続的かつ直線的に増加あるいは減少する。この場合
、注意すべきことは運転員の操作が操作スイッチ1の増
、減各々の接点の開閉とその状態の保持に限られている
ことである。The opening degree detector 4 detects the opening degree of this valve, etc., and the opening degree display meter 5Ki1 degree is displayed. The f-land operator continues operating the operation tube while checking the indicated value of the laparotomy display instrument 5, and stops operating the operation switch when the degree of laparotomy reaches the desired value. In this operating method, as the operating switch 1 is opened or closed, the set value increases or decreases continuously and linearly with respect to the operating time, as shown in the graph of FIG. In this case, it should be noted that the operator's operations are limited to opening and closing the increase and decrease contacts of the operating switch 1 and maintaining that state.
従って、第2図において、現在の設定値S・がら次の設

しかし、上記のように設定操作は限られているためどう

る一足の変化率以下でないと調整がむずかしくなるので
ある。従って、調定値の範囲が広くかつ一定の設定精度
t−要求される場合にはど2しても時間tl−t・が大
きくなる。Therefore, in Fig. 2, when trying to change the current set value S to the next set value SR, the operator holds the operating switch 1t in the closed state for a time tl -1, regardless of the state variables of the plant. If the ground state quantity has good responsiveness and can sufficiently follow the set value change rate even if it is relatively large, the operator would want to adjust it to the set value Sm as soon as possible. Must,
However, since the setting operations are limited as described above, it takes time just for tl-to. Also, if the rate of change of the set value is made large, tt -t can be kept small, but then the adjustment will be slow and difficult. If the rate of change is less than one pair, it will be difficult to make adjustments. Therefore, if the range of adjustment values is wide and a constant setting accuracy t- is required, the time tl-t will become long in any case.
そこで考えられるのが、設定値の変化率を2段階に切替

、スイッチを4段階に切替えることにより操作が複雑に
なるという欠点がある。A possible solution to this problem is to switch the rate of change of the set value into two stages. In addition to the increase/decrease contacts of the Fi operation scheme 1, a contact point 'tiFr7t for rapid increase or decrease can be provided, and can be realized by these four ON%OFF signals. but,
This method has the disadvantage that the structure of the operation switch l becomes complicated, and the operation becomes complicated by changing the switch into four stages.

以下、本発明を第3@乃至第6図に示す実施例を参照し

リックな処理を行う場合を考える。In FIG. 3, this device includes an operation switch 1 for manual operation, an adjustment calculation device 6, an output device 7 for calculation results,
It consists of an electric motor 3 driven by an output device via an interface circuit 2, an opening detector 4, and a display instrument 5 that displays a set value or ground state quantity tsg. I'm nine,
In recent W411E operations, automatic operations such as computers are generally performed in parallel with manual operations while driving, and the command 8 from the computer is also input as well as from the operation switch 1. This implementation [6Fi is required not only for input from the operation switch 1, but also for processing input from the computer. Consider the case where cyclic processing is performed using a data processor.
次に1本発明の詳細な説明する。Next, one aspect of the present invention will be explained in detail.
本発明の基本的な考え方は、第4図のグラフに示すよう

にして、閉信号が入っている時には時刻2TにおけるΔ
8が出力され、開信号が入った時にはΔ8■Oとなる。The basic idea of the present invention is to change the rate of change of the set value depending on the contact closure time of the operation switch, as shown in the graph of FIG. Here, the curve in Fig. 4 is assumed to be a quadratic curve with Δ5=at2 (1) ΔS: set value 1: constant t: operating switch contact closing time, and calculate Cyclically increases (decreases) in device 6 with periodic
The operation of the arithmetic unit 6 will be explained with reference to FIG. 5, assuming that it reads the contact signal sound. Considering the first scan t of the arithmetic unit 6, when the read increase (decrease) signal is an open signal, 0 is put in register address R000, and when the - (decrease) signal is a close signal, 0 is put in register address R000. Next, enter the operation result of register address ROOIKaX (ROOO)X (fooo) (however, (ROOO) is the register address R
(represents the contents of OOO), the result of this operation is the above (1)
In the formula, @ROO means ΔS at time τ
Of course, if O contains O, then (ROOI) = ΔS =

! Considering the case of changing to t, in the conventional method,
It took only 1 time, but by using this device, the set value 81 can be set accurately in a short time as follows. That is, by closing the addition point of operation switch 1. If you set and hold, the setting value will initially increase gradually, then
Eventually, it will increase significantly. Then ζ, set value Sl
If you open the contact near the point (between point L and point U in Figure lI6) and fully close the increase or decrease contact again, the value will gradually increase to the set value S.
Since it is close to 1, it can be easily set to the desired set value S1.

るのである。Furthermore, the plant operator performs the above operations while looking at the display instrument 5 in FIG.
If the display method is digital, the settings will be more accurate and easier. At first, the first digit begins to increase slowly, and then the second digit gradually increases. Then, by opening the operating switch near the set value SR and closing it again, the first digit will slowly increase, making it really easy to set an accurate value.
尚、以上の実施例では、第4図の曲線t−21i関数と

間の感覚も無理なく追従できる。In the above embodiments, the curve t-21i function in FIG. 4 was explained, but if necessary, it may be a curve of various functions other than quadratic functions. A method of changing the rate of change in stages may be considered, but this would make it difficult for the operator to keep up with the changes.Although the rate of change in the set value changes continuously as in the present invention, it is not unreasonable for human senses to follow.

In addition, operations and confirmations that are well suited to human senses can be performed.
