[0001]
[Industrial application fields]
The present invention relates to a controller increase / decrease device for operating a nuclear power plant, for example.
[0002]
[Prior art]
Conventionally, in a nuclear power plant or the like, a controller increasing / decreasing device has been used to operate a controller for adjusting an output such as a process amount. In recent years, this controller increasing / decreasing device also has a user interface, that is, a switch or the like. There is an urgent need to improve the operation mode.
[0003]
Here, a conventional controller increasing / decreasing device will be described with reference to FIG.
[0004]
In FIG. 7, the conventional controller increasing / decreasing device includes a control panel 70 and a control device 80. On the control panel 70, a controller 71 and hard switches (such as an increase switch 72, a decrease switch 73, and a high speed switch 74) for increasing or decreasing the controller 71 are arranged. A control arithmetic unit 81 of the control device 80 is connected to each switch 72, 73, 74 of the control panel 70. The control calculation unit 81 sets the value of the controller 71 based on the increase command G, the decrease command H, and the high speed command I transmitted from the increase switch 72, the decrease switch 73, and the high speed switch 74. The control device 80 is provided with an output processing unit 82. The output processing unit 82 performs processing for displaying the value set by the control calculation unit 81 on the controller 71.
[0005]
In this controller increase / decrease device, there are two types of increase / decrease rate (increase / decrease pitch) of the controller 71: normal rate and high speed rate.
[0006]
For example, the increase / decrease rate is selected by selecting the normal rate when only the increase switch 72 is used, selecting the high rate when the increase switch 72 and the high speed switch 74 are used together, and using only the increase switch 72 again. In this case, the system can easily select the normal rate.
[0007]
For example, when the controller 71 is increased at a normal rate, the user presses only the increase switch 72.
[0008]
Then, the increase command G is transmitted from the increase switch 72 to the control calculation unit 81 only while the increase switch 72 is being pressed. While the increase command G is transmitted, the control calculation unit 81 increases the value of the controller at the normal rate.
[0009]
When the controller is increased at a high rate, the user presses the increase switch 72 and the high speed switch 74 at the same time.
[0010]
Then, the increase command G and the high speed command I are transmitted to the control calculation unit 81 only while the respective switches 72 and 74 are being pressed. The control calculation unit 81 increases the value of the controller 71 at a high rate while the increase command G and the high speed command I are transmitted.
[0011]
Further, the value of the controller 71 can be reduced by replacing the increase switch 72 with the decrease switch 73 and the increase command G with the decrease command H.
[0012]
That is, the value of the controller 71 is set in the control calculation unit 81 based on the increase command G, the decrease command H, and the high speed command I transmitted from the increase switch 72, the decrease switch 73, and the high speed switch 74.
[0013]
The value J set by the control calculation unit 81 is transmitted to the output processing unit 82, and the output processing unit 82 performs a process for displaying on the controller 71. This display processing result, that is, the value K of the controller is transmitted to the control panel 70, and the value K is displayed on the controller 71.
[0014]
On the other hand, in recent years, instead of the above-described hard switches such as increase / decrease / high speed, input of increase / decrease / high speed commands using a touch panel is being implemented.
[0015]
In this case, three touch areas of increase / decrease / high speed are set on the touch panel, and by touching each area, a corresponding increase command, decrease command, and high speed command are output.
[0016]
In this touch panel, when the value of the controller 71 is increased or decreased by the same operation as before, there are a normal rate and a high speed rate. You will be pressing two touch areas at the same time.
[0017]
However, in the case of this type of touch panel, the user cannot press a plurality of touch areas accurately at the same time, so that the operation on the touch panel always shifts in time and a continuous touch occurs.
[0018]
In this continuous touch, high-speed touch is made after touching an increase. In this case, the controller 80 has a restriction that only the command of the touch area touched last is output. When an increase command is output at, and then a high speed is touched, the output of the increase command is canceled and a high speed command is output, and eventually only one command is output.
[0019]
[Problems to be solved by the invention]
As described above, in the conventional controller increase / decrease device described above, it is impossible to output high speed and increase commands simultaneously due to the mechanism of the touch panel and restrictions on the control device. There was a problem that only one of them could be output and the increase / decrease command could not be operated at a high rate.
[0020]
Also, contrary to the restrictions of the touch panel, if it is possible to output commands for two touch areas, the controller value can be increased at the normal rate if only the increased touch is performed. If done further, the value of the controller can be increased at a high rate. However, after the adjustment at the high rate, in order to increase the normal rate again, it is necessary to release the high-speed touch and establish only the increased touch. In general, the operation of the touch panel is to output a command corresponding to the touched area, and it is impossible to cancel the command of the touched area.
[0021]
Therefore, in order to increase the normal rate again from the high speed rate, the user must perform an operation different from the conventional one, such as clearing all touch data and then touching the increased area to increase the normal rate.
[0022]
Furthermore, when a touch panel is used, the touched touch area command cannot be output for an arbitrary time. For example, when increasing is touched, an increase command is output. However, since this increase command continues to be output until a touch other than an increase is made, when this command is used as it is, it is difficult to set the value of the controller to an arbitrary value.
[0023]
The present invention has been made to solve such problems, and when using a touch panel, the controller value is increased or decreased by combining a plurality of commands without greatly changing the operability of the conventional hard switch. It aims at providing the controller increase / decrease apparatus which can be performed.
[0024]
[Means for Solving the Problems]
In order to achieve the above-described object, the controller increase / decrease device according to claim 1 has a plurality of touch areas, and when each area is touched, touch data corresponding to each area is obtained. Output by touching a touch area with the touch panel provided in the input means and the touch means provided in the input means, a touch panel for outputting, and a hard switch A conversion unit that converts touch data into a control command, a holding unit that holds the control command converted by the conversion unit for a predetermined period, and a touch from the touch input unit during a period in which the control command is held by the holding unit When data is output, command establishment means for simultaneously establishing the control instruction held by the holding means and the control instruction converted by the conversion means; Command creation means for creating one command from a control command established by the command establishment means and a signal output while the hard switch is ON; It has.
[0026]
Claim 2 The controller increase / decrease device described is Claim 1 In the controller increase / decrease device described above, the calculation means for calculating the increase / decrease value of the controller based on the command created by the command creation means, and the value of the controller according to the increase / decrease value calculated by the calculation means Display means.
[0027]
[Action]
According to the first aspect of the present invention, the touch data output from the touch input means is converted into a control command, which is held in the holding means for a predetermined period, and the control command and the control held during that time are held. Establish two instructions with the instruction.
[0028]
Therefore, the same control as that performed simultaneously with the conventional hard switch can be performed, and the value of the controller can be increased or decreased without greatly changing the operability as compared with the conventional case.
[0031]
further , Claim 1 In the described invention, by using the touch panel and the hard switch together, a command created by touching the touch panel can be executed by pressing the hard switch.
[0032]
Therefore, the value of the controller can be increased or decreased safely without erroneous operation.
[0033]
Also , Claim 2 In the described invention, the increase / decrease value of the controller is calculated based on the created command, and the value of the controller is displayed by the display means according to the increase / decrease value of the calculation result. Therefore, the user can easily increase or decrease the value of the controller while using the touch panel and the hard switch while watching the value of the display means.
[0034]
As described above, it is possible to increase or decrease the controller using the touch panel without greatly changing the switch operation which has been performed only with the conventional hard switch.
[0035]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0036]
FIG. 1 is a diagram showing a configuration of a controller increase / decrease device according to an embodiment of the present invention.
[0037]
In the figure, reference numeral 10 denotes a control panel. On the control panel 10, a display screen 11 for displaying a control state, a touch panel 12 disposed on the display screen 11, and a hard switch 13 are installed. On the display screen 11, a plurality of operation images such as increase / decrease / high speed, a scale 11a of a controller, a bar 11b of an adjustment value, and the like are displayed. Touch areas 12a, 12b, and 12c having a predetermined width are provided at positions of the touch panel 12 corresponding to respective operation images (increase / decrease / high speed, etc.).
[0038]
Reference numeral 20 denotes a control device that controls the control panel 10. The control device 20 includes an input processing unit 30, a control calculation unit 21, an output processing unit 22, and the like. The input processing unit 30 includes a touch data processing unit 31, an instruction processing unit 32, and a plurality of AND circuits 33, 34, and 35. The control calculation unit 21 receives a command from the command processing unit 32 and performs an increase / decrease calculation of the value of the controller. The output processing unit 22 creates data for displaying the increase / decrease result of the controller on the display screen 11. The touch data processing unit 31 converts the signal A output from the touch panel 12 into a command. The command processing unit 32 receives the command processed by the touch data processing unit 31, determines the type of the command, performs direction determination such as increase / decrease and rate determination such as normal / high speed. Each AND circuit 33, 34, 35 receives a command signal output in accordance with the direction and rate determined by the command processing unit 32 and a signal from the hard switch 13. Therefore, each AND circuit 33, 34, 35 not only outputs an increase command or a decrease command alone, but also includes a combination of an increase command and a high speed command, a combination of a decrease command and a high speed command, and the like. Two commands may be output at the same time.
[0039]
As shown in FIG. 2, the command processing unit 32 of the input processing unit 30 includes a memory 40 having a control command storage location divided into an increase touch 40a, a decrease touch 40b, a high-speed touch 40c, and other touches 40d. A satisfaction condition part 41 and a failure condition part 42 for making each instruction satisfied or not satisfied by a signal output from each control instruction storage location of the memory 40, an increase hold circuit 43 for holding the result of each condition being satisfied or not, The circuit includes a hold circuit 44, a high-speed hold circuit 45, a high-speed release circuit 46, and the like.
[0040]
The high-speed release circuit 46 is composed of an AND (AND) circuit, a NAND (NAND) circuit, and the like. When a high-speed touch output (high-speed command) is being input and a high-speed command is input again, the high-speed command is not output. This is to cancel the so-called high speed condition. The establishment condition unit 41, the failure condition unit 42, and the hold circuits 43, 44, and 45 are to establish or fail a command for an arbitrary time.
[0041]
In the case of this controller increase / decrease device, a command when the touch panel 12 is operated by an operator (user) is sent to the control device through the touch areas 12a, 12b, 12c and the hard switch 13 in the touch panel 12 while confirming the display screen 11. 20 Touch data from the touch panel 12 is input to the touch data processing unit 9 of the input processing unit 30 in the control device 20. The touch data processing unit 9 recognizes which area is touched based on the input touch data, selects a control command, and transmits it to the command processing unit 32. The command processing unit 32 creates a command to be transmitted to the control calculation unit 21 based on the control command.
[0042]
Hereinafter, the command creation processing of the command processing unit 32 will be described with reference to FIG.
[0043]
When the command processing unit 32 receives a control command from the touch data processing unit 31 (step 301), first, the type of the received control command, for example, whether the control command is an increase / decrease / high speed or other command is determined. Identified (step 302).
[0044]
Here, the control command is stored in the increased touch area 40a of the memory 40, and is output from the command (increased touch command), and this increased touch command is input in a state where “increase” has not been selected before. If so, the command processing unit 32 performs an increasing direction selection process (step 303) and cancels the decreasing direction selection (step 304). Then, the command processing unit 32 establishes the increase selection command C and determines the increase / decrease direction as the increase direction (step 305).
[0045]
When the control command is input from the decrease touch area 40b after the increase selection process is performed (step 306), the command processing unit 32 performs the decrease selection process (step 307) and establishes the decrease selection command D. In the decrease selection process in step 307, the previous increase selection command C is not established, that is, is canceled.
[0046]
Further, when only the increase selection command C is established and the type of the control command input is a high-speed command input from the high-speed touch area 40c (step 302), the command processing unit 32 currently It is determined whether or not the high speed selection command E is established (step 308).
[0047]
Here, when the switch selection has progressed as described above, since the high-speed selection command E has not been established before (No in Step 308), the instruction processing unit 32 performs the high-speed selection processing (Step 309). Then, the high speed selection command E is established, and the rate is determined at a high speed (step 310). At this time, the increase selection command C is kept established. As a result, two selection commands, ie, an increase selection command C and a high speed selection command E, are established, and the established selection commands are output to the AND circuits 33, 34, and 35.
[0048]
After the selection command is established, when the user operates the hard switch 13 (turns on the switch 13) (step 311), the execution command F is output to the AND circuits 33, 34, 35, and the AND circuits 33, 34, The logical product (AND) of the execution command F, the increase selection command C, the decrease selection command D, and the high-speed selection command E is obtained by 35, and the command is executed (step 312).
[0049]
In step 308, if the high-speed selection command E has been previously established (Yes in step 308), the high-speed selection is canceled by the high-speed release circuit 46 (step 313), and the rate is determined as the normal rate.
[0050]
Further, in step 302, if the control command is a command other than increase / decrease / high speed, all currently established commands (increase selection command C, decrease selection command D, high speed selection command E, etc.) It is canceled (is not established) (step 314). This prevents the controller from being increased or decreased.
[0051]
On the other hand, the logical product obtained by each AND circuit 33, 34, 35 becomes an increase command G, a decrease command H, and a high-speed command I, respectively, and is input to the control calculation unit 21. When only the increase selection command C is established, only the increase command G is output to the control calculation unit 21, and the value of the controller is increased at the normal rate.
[0052]
When the increase selection command C and the high speed selection command E are established, the increase command G and the high speed command I are output to the control calculation unit 21 to increase the value of the controller at a high rate.
[0053]
Here, the increase command G, the decrease command H, and the high-speed command I are all the logical products of the execution command F and each selection command. The establishment time of the high speed command I is the time when the execution command F is established. For this reason, the execution command F is established only while the hard switch 13 is being pressed, and the time for inputting the increase command G, the decrease command H, and the high-speed command I to the control arithmetic unit 21 by the hard switch 13 can be adjusted. The control calculation unit 21 transmits the value J of the controller that has increased or decreased to the output processing unit 22. The output processing unit 22 performs data processing for displaying the value of the controller on the display screen 11 and creates display data. The output processing unit 22 transmits the processed display data K to the display screen 3 on the control panel 1. On the display screen 11, the bar 11 b is changed and displayed on the scale 11 a of the controller based on the received display data K.
[0054]
Next, a case where the control command first input by touching is “high speed” will be described.
[0055]
First, when each touch area is not selected and the touch area 12c on which high speed is displayed is touched and a high speed control command is output from the touch panel 12 to the command processing unit 32, in step 308, the command processing unit 32 Determines whether the high-speed selection command E is established. In this case, since the high-speed selection command E has not been established, the instruction processing unit 32 performs a high-speed selection process in step 309 to establish the high-speed selection command E.
[0056]
If an increase control command is input while the high-speed selection command E is established, the command processing unit 32 performs an increase selection process in step 303 to establish the increase selection command C. At this time, the high-speed selection command E is kept established. Also by this method, two commands, the increase selection command C and the high speed selection command E, are established.
[0057]
When two commands such as increase and high speed are established in this way, an increase selection command can be made by touching high speed after increasing touch regardless of the order of touching or touching increase after touching high speed. C and the high-speed selection command E can be established at the same time.
[0058]
Next, the case where the high-speed selection command E once selected is canceled will be described.
[0059]
For example, it is assumed that the high-speed touch area 12c has already been touched and the high-speed selection command E has been established.
[0060]
If the touch area 12c with a higher speed is touched in this state, in step 308, the command processing unit 32 determines whether or not a high speed selection command is established. At this time, since the high-speed selection command E has already been established, the instruction processing unit 32 performs a high-speed selection release process in step 313, and the high-speed selection command E is not established. As a result, the increase / decrease rate is changed from the high rate to the normal rate.
[0061]
Subsequently, as another example, a case where an increase selection command C and a high-speed selection command E are first established will be described.
[0062]
In this case, when the high-speed touch area 12c is touched and a high-speed control command is input as a control command to the command processing unit 32, in step 308, the command processing unit 32 determines whether or not the high-speed selection command E is established. Determine. At this time, since the high-speed selection command E is established, the process proceeds to step 313, where the instruction processing unit 32 performs a high-speed selection release process, and the high-speed selection command E is not established. At this time, the increase selection command C is kept established. Thus, since only the increase selection command C is established, it is possible to change the rate from an increase due to the high-speed rate to an increase due to the normal rate. At this time, regardless of the order in which the increase selection command C and the high speed selection command E are established, the high speed selection command E is not satisfied even if the high speed is touched after the two commands are established in the order of high speed → increase. The high-speed selection command E can be made unsatisfied by touching high-speed after two commands are made in the order of increase → high-speed.
[0063]
Hereinafter, each command establishment timing when a control command is input will be described with reference to FIGS.
[0064]
Touch data input from the touch panel 12 is transferred to the touch data processing unit 31. The touch data processing unit 31 determines what command is input from the touch panel 12 and transmits the command to the command processing unit 32. At this time, only one control command from the touch data processing unit 31 to the command processing unit 32 is transmitted. Next, when a different control command is transmitted from the touch data processing unit 31 to the command processing unit 32, the previously transmitted control command is cleared. The command processing unit 32 stores the control command received from the touch data processing unit 31 in the corresponding control command storage locations 40 a to 40 c of the memory 40.
[0065]
For example, when the control command stored in the memory 40 is increased, the increase hold circuit 43 establishes the increase selection command C at the timing shown in FIG. When the input from the next touch panel 12 is decreased, the increase hold circuit 43 does not establish the increase selection command C, and the decrease hold circuit 44 establishes the decrease selection command D. When the next touch input is high speed, the increase hold circuit 43 does not establish the increase selection command C, and the high speed hold circuit 45 establishes the high speed selection command E.
[0066]
If a high-speed control command is stored in the memory 40 while the controller value is being increased at the normal rate, as shown in FIG. 5, in addition to the increase selection command C in which the increase hold circuit 43 is established. Then, the high speed hold circuit 45 establishes the high speed selection command E. If the high speed control command is stored in the memory 13 again when the increase selection command C and the high speed selection command E are established, the increase hold circuit 43 keeps the increase selection command C established, but the high speed hold circuit 45 makes the high-speed selection command E not established.
[0067]
Further, when a high speed is touched when no touch selection is performed, the high speed hold circuit 45 establishes a high speed selection command E as shown in FIG. When the high speed is touched again, the high speed hold circuit 45 makes the high speed selection command E not established. In the case of a combination of reduction and high speed, it can be realized by replacing the increase with a decrease. Any of the hold circuits 43, 44, 45 makes the increase selection command C, the decrease selection command D, and the high speed selection command E unsatisfied when a touch other than increase / decrease / high speed is performed.
[0068]
After the touch input is performed as described above and the command is established, the command is executed while the hard switch 13 is being pressed. For example, when the increase selection command C is established, the logical product of the execution command F from the hard switch 13 and the increase selection command C is transmitted to the control calculation unit 21 as the increase command G. Similarly to the increase selection command C, the decrease selection command D and the high speed selection command E are ANDed with the execution command F and are transmitted to the control calculation unit 21 as the decrease command H and the high speed command I, respectively.
[0069]
That is, an increase command G, a decrease command H, and a high-speed command I obtained by ANDing an execution command F, which is an output signal of the hard switch 13, and an increase selection command C, a decrease selection command D, and a high-speed selection command E 21, the increase command G, the decrease command H, and the high speed command I are output to the control calculation unit 21 only while the execution command F is established, that is, while the hard switch is pressed, and the controller is increased or decreased. it can.
[0070]
As described above, according to the controller increase / decrease device of the present embodiment, two commands such as increase and high speed or decrease and high speed can be performed by continuous touch input from a plurality of touch areas 12a, 12b, and 12c of the touch panel 12. Can be combined (combined).
[0071]
In addition, when the user accidentally selects a rate such as a high-speed command on the touch panel 12, selecting the same area again causes the high-speed release circuit 46 to fail to establish a high-speed selection command and cancel the high-speed rate. Therefore, the erroneous selection is canceled, and then the correct setting can be performed to input the setting value of the controller without any erroneous operation.
[0072]
In addition, for example, when the operation B or the operation C can be selected as the selection after the operation A, the operation A must actually be selected, but when the operation C is selected, the operation A is not established. Operation A and operation C are established.
[0073]
Therefore, if the operation C is selected again, the operation C is not established, and the operation A and the operation B to be originally performed can be selected by selecting the operation B again.
[0074]
Furthermore, by using the touch panel 12 and the hard switch 13 together, a command (increase command, decrease command, high-speed command, etc.) determined by touching the touch panel 12 is output to the control calculation unit 21 only while the hard switch 13 is pressed. As a result, the value K of the controller is increased / decreased, so that the value of the controller can be easily increased / decreased easily and reliably without erroneous operation without greatly changing the operability of the conventional hard switch. In addition, when a command other than an increase control command, a decrease control command, or a high-speed control command is input, all the commands that have been selected so far are not established, so that the commands are not combined and erroneous operation can be prevented. .
[0075]
The hard switch 13 can be used in combination with the touch panel 12 as means for starting a final execution command of a control command selected by the touch panel 12 in addition to an operation for establishing a command for an arbitrary time.
[0076]
For example, if the touch-selected one is executed as it is as an operation command, the command is executed when the user erroneously operates the touch panel 12, and it is extremely dangerous when performing output control of a nuclear power plant or the like.
[0077]
Therefore, if the touch panel 12 and the hard switch 13 are used together, all the input contents are confirmed when the selection operation is performed on the touch panel 12, and then the final controller value is increased or decreased by pressing the hard switch 13. If so, the correct command can be output.
[0078]
As a result, when the touch panel 12 is used, the value of the controller can be increased or decreased by combining and combining a plurality of commands without greatly changing the operability as compared with the case of using only the conventional hard switch.
[0079]
In the above-described embodiment, it is used to control three commands such as increase / decrease / high speed. However, the present invention can be applied to general touch operations other than the above-described embodiment.
[0080]
That is, the three commands are replaced with, for example, operation A, operation B, operation C, and the like, and two operations such as operation A + operation B and operation A + operation C are performed to control a certain control device. These two operations are performed continuously for the purpose of preventing erroneous operations. However, because of restrictions on the touch panel, the two commands cannot be established at the same time, and in this case as well, the present invention can be applied as in the above embodiment.
[0081]
【The invention's effect】
As described above, according to the first aspect of the invention, the touch data output from the touch input means is converted into a control command, which is held in the holding means for a predetermined period, and the control converted during that time is converted. Since the two commands of the command and the held control command are established, the same control as the simultaneous pressing performed by the conventional hard switch can be performed, and the operability is greatly changed compared to the conventional case. Without changing the value of the controller.
[0083]
further , Claim 1 According to the described invention, since the command created by touching the touch panel can be executed by pressing the hard switch by using the touch panel and the hard switch together, the value of the controller can be increased or decreased safely without erroneous operation. .
[0084]
Also , Claim 2 According to the described invention, the increase / decrease value of the controller is calculated based on the created command, and the value of the controller is displayed by the display unit according to the increase / decrease value of the calculation result. While looking at the value, the value of the controller can be easily increased or decreased by using the touch panel and the hard switch together.
[0085]
As described above, the controller can be increased or decreased using the touch panel without greatly changing the conventional operability.
