Abstract

PURPOSE:To perform the operation and confirmation in good matching to human sensibility easily with fast and accurate setting, by the constitution that a set value with variable rate of change from slow to fast rate automatically and continuously is outputted with one signal. CONSTITUTION:When an ''increase'' contact of an operation switch 1 is closed and held, a set value is increased at first little by little and gradually greatly increased. Then, the contact is opened around a set value S1. The ''increase'' or ''decrease'' contact is closed and the value is closed to the set value S1 little by little, allowing to set the prescribed set value S1 easily. The plant operator performs the said operation while observing a display meter 5. In this case, the 1st digit is slowly increased at first an then the 2nd digit is gradually increased. The operation switch is opened around the set value S1 and again closed, allowing to increase the 1st digit gradually and to obtain easy and accurate setting.

Description

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.

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.

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.

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.

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.

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.

This is an unavoidable drawback whether the four contacts are combined into one switch or independently provided, or whether two two-stage changeover switches are used.

An object of the present invention is to provide a setting device that is easy to operate and can quickly and accurately provide control settings, in response to the above-mentioned technical solution requirements.

The present invention will be described below with reference to embodiments shown in FIGS. 3 to 6.

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.

Next, one aspect of the present invention will be explained in detail.

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 =
0tea! If l, ROOOK↑ is included, (RO
OI) Day Δ8 = a T2. Similarly for the second scan, when the close signal is input, Δ at time 2T
8 is output, and when the open signal is input, it becomes Δ8■O.

In this way, continue reading the close signal @ri2g(to
T) #Δg(to27).

2g(t-3'r),... Since the set value increment 11B shown in FIG. At first, it changes little by little, but as the closed state continues to be maintained, the change becomes larger.

Therefore, for example, in FIG. 6, from the set value t-s
! 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.

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.

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. Can follow.

As described above, the present invention is configured to automatically output a setting value whose rate of change changes continuously from slow to sudden with one signal, so operation is easy, quick, and accurate. In addition, operations and confirmations that are well suited to human senses can be performed.
