Abstract

PROBLEM TO BE SOLVED: To scroll a waveform chart displayed on a monitor, in the same sense as pulling out or rewinding a piece of rolled waveform chart paper.SOLUTION: In the tracking scroll in S107, executed is a process that makes a waveform chart track and scroll according to movement of a fingertip F moving on a monitor 2. On the monitor 2, the waveform chart is tracked and scrolled, at almost the same speed as a speed at which the fingertip F moves and in a direction in which the fingertip F moves. In S118, immediately after an operator makes the fingertip F come free from the monitor 2, a moving speed of the fingertip F is calculated by a moved distance and a required time from a time point when the operator touches the monitor 2 to start moving the fingertip F to a time point when the fingertip F comes free from the monitor 2. If the moving speed is higher than a threshold, scroll, at a fast-forward speed corresponding to a moving speed from when a first touch is performed to when command means such as the fingertip F comes free from the monitor 2, is executed in S120.

Description

  The present invention relates to a waveform observation apparatus.

  Waveform observation equipment is used in the factory production line to observe equipment temperature and pressure. Historically, waveforms were written on rolled paper, but with the development of electronic equipment, waveform observation devices that display using a monitor instead of paper are now widespread.

  While the waveform observation apparatus stores measurement data taken from a thermocouple or the like in a memory, the waveform observation apparatus can display a measurement value that changes from time to time on a monitor (for example, Patent Documents 1 and 2). Patent Documents 1 and 2 disclose a waveform observation apparatus provided with a display with a touch panel. Patent Document 1 proposes that an operator touch a function key displayed on the display to execute a function designated by the displayed function key on the display. Japanese Patent Application Laid-Open No. H10-228561 proposes to perform a comment or marking input operation while observing a display waveform by pen input using a touch screen capable of pen input.

Japanese Patent Laid-Open No. 7-114349 JP 2002-82133 A

  Incidentally, the waveform observation apparatus stores a large amount of measurement data in a memory and displays a part of the measurement data on the display in the form of a waveform chart. However, since the storage capacity of the general-purpose memory has increased, for example, the past When it is attempted to refer to the measured data, there is a demand for displaying the measured data easily and quickly on the display.

  The present invention has been devised to meet this demand, and its purpose is to provide a waveform observation apparatus capable of quickly displaying a desired waveform chart on a display by an operation on a monitor of command means such as an operator's fingertip. Is to provide.

  Another object of the present invention is to scroll the waveform chart displayed on the monitor in the same sense as the operation of pulling out and rewinding the rolled-up waveform chart paper, pulling out at a stretch, rewinding at a stretch and the operation. An object of the present invention is to provide a waveform observation apparatus capable of performing the above.

According to the present invention, the above technical problem is
In the waveform observation device for storing the measurement data received from the outside in the memory, generating the waveform chart, and displaying the waveform chart on the monitor along the time axis,
A touch panel disposed in front of the monitor;

Based on an operation of touching the waveform chart display area of the monitor in the touch panel and paying the touch in the time axis direction, the waveform chart can be fast-forwarded in the time axis direction immediately after the touch on the touch panel leaves the touch panel. This is achieved by providing a waveform observation device characterized by having a fast-forward scroll means for scrolling.

  That is, according to the present invention, the operator directly touches the monitor displaying the waveform chart with a command means such as a fingertip, and the displayed waveform chart scrolls on the monitor according to this touch operation. A desired waveform chart can be quickly displayed on the monitor from a large amount of measurement data accumulated in the waveform observation apparatus.

  Based on the touch operation, the follow-up scroll and the fast-forward scroll can be used properly, and the monitor waveform chart can be scrolled in the same sense as the operation of pulling out or rewinding the rolled-up waveform chart paper. . In other words, the operator uses two types of scrolling modes according to the difference in touch operations, so that the operator can quickly and accurately select from the measurement data stored in the waveform observation device in a mode that matches the operator's feeling. A desired waveform chart can be displayed on the monitor.

It is a figure for demonstrating. It is a figure for demonstrating that two waveform charts are displayed on a monitor and the scroll by operation of the fingertip F can be applied with respect to each waveform chart. It is a figure for demonstrating that the scroll by the fingertip F can be applied with respect to the front waveform chart when another waveform chart is superimposed and displayed on one waveform chart.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of the waveform observation apparatus 1 according to the embodiment. The waveform observation apparatus 1 has an open / close lid 3 that opens on the lower hinge below the monitor 2, releases the slide lock 4, and opens the open / close lid 3 around the lower hinge 5. As shown, the main power switch 6, the start / stop switch button 7, the setting menu button 8, the operator key button 9, the touch panel function lock switch button 10, and the USB port 11 can be exposed.

  3 is an exploded perspective view of the waveform observation apparatus 1, and FIG. 4 is a block diagram thereof. The waveform observation apparatus 1 includes a main body 20 and a front unit 22 that can be attached to and detached from the front surface of the main body 20. The front unit 22 includes a decorative panel 220, a front frame 221, a touch panel 222, and a liquid crystal display 224 including a backlight 223 (FIG. 4). The monitor 2 is configured by the touch panel 222 and the liquid crystal display 224 with backlight. It is configured.

  The main body 20 includes a relay board 201 positioned in front of the main board 202 and standing upright, and a main board 202 connected to the upper end of the relay board 201 and extending in the horizontal direction. The relay 201 includes ten measurement units. Connector 203 and four IO unit connectors 204 are provided. The relay substrate 201 and the main substrate 202 are accommodated in the main body case 205.

  The main body case 205 is composed of a metal outer case 206 and an inner plastic case 207. The plastic case 207 is formed with left and right multi-stage shelves for accommodating the measurement unit 23 and the IO unit 24. Yes. The measurement unit 23 and the IO unit 24 can be connected to each other by inserting them into the shelf of the plastic case 207 from the rear. That is, in the standing state, the relay board 201 positioned in front of the plastic case 207 is provided with connectors 203 and 204 at positions corresponding to the respective shelves of the plastic case 207, and the measurement unit 23 or the IO unit 24 is A connector can be connected to the relay board 201 by inserting it into each shelf of the plastic case 207. By adopting such a configuration, the waveform observation apparatus 1 can be reduced in size.

  The measurement unit 23 and the IO unit 24 are respectively provided with terminal blocks 25 and 26 on the back (FIG. 4), and the terminal block 25 of the measurement unit 23 has a thermocouple, a resistance temperature detector, a flow meter, a pressure. Various sensors 27 such as sensors are connected. When the in-unit microcomputer 28 receives a signal from the sensor 27, it communicates with the microcomputer 29 of the main board 202 via the relay board 201 and transmits the measurement data received from the sensor 27 to the main board 202.

  The microcomputer 29 of the main board 202 performs signal processing according to a predetermined program, stores measurement data in the memory 30, and generates an image signal for controlling drawing on the liquid crystal display 222 (monitor 2). The main substrate 202 and the liquid crystal display 222 are connected via the relay substrate 201. When the operator touches the touch panel 222, a touch position signal or a coordinate signal corresponding to the touch panel 222 is supplied from the touch panel 222 to the microcomputer 29 of the main board 202, and the microcomputer 29 realizes a function that the key that represents the touch position means. Alternatively, a signal for executing scrolling of the waveform displayed on the monitor 2 is generated based on the coordinate signal.

  The waveform observation apparatus 1 is installed on a control panel 32 (FIG. 4) in the factory, and can be connected to a personal computer 34 via the factory LAN 33. The personal computer 34 displays the waveform displayed on the waveform observation apparatus 1. The same waveform can be displayed. The data stored in the memory 30 of the waveform observation apparatus 1 can be taken out by inserting the USB memory 26 into the USB connector 11.

  A waveform chart is displayed on the monitor 2 of the waveform observation apparatus 1 as illustrated in FIG. In the waveform chart illustrated in FIG. 1, the horizontal axis is the time axis, the time advances in the right direction, and the right side is newer in time than the left side. When the display mode of FIG. 1 is called a horizontal display mode, of course, the display of the waveform chart is not limited to this. For example, the time axis is vertical, the time progresses upward, and the upper one is lower than the lower one. It may have a new vertical display mode in time, and it is preferable that the vertical display mode and the horizontal display mode can be arbitrarily switched by an operator's setting operation.

  In the horizontal display mode of FIG. 5, when the operator wants to refer to past measurement data, for example, touch the monitor 2 with a scroll direction display 40R, for example, a right scroll direction display 40R of 40L, for example, indicating the scroll direction of the display. The waveform chart displayed in FIG. 2 starts to scroll in the right direction at a predetermined speed, and as long as measurement data exists, the right scroll can be continued by continuing to touch the scroll direction display 40R. Of course, to scroll the waveform chart in the left direction, the left scroll direction display 40L may be touched. When the left scroll direction display 40L is touched, the waveform chart starts scrolling to the left, and as long as measurement data exists, the left scroll direction display 40L is continuously touched to scroll the waveform chart displayed on the monitor 2 to the left. You can continue.

  Apart from this, the waveform chart can be scrolled by touching the waveform chart display area 41 where the waveform chart is displayed on the monitor 2 with a command means such as the fingertip F. In FIG. 5, by sliding the fingertip F in the time axis direction, that is, in the x-axis direction that is the horizontal axis in terms of the coordinates of the waveform chart display area 41, the sliding direction corresponds to the sliding direction and speed of the fingertip F. The waveform chart can be scrolled in the same direction and at the same speed as the slide speed. The example of FIG. 5 shows an example in which the fingertip F is slid in the right direction. In this example, the waveform chart displayed on the monitor 2 following the sliding operation of the fingertip F and the sliding speed of the fingertip F in the right direction. Scroll at the same speed. In this follow-up scroll, when the command means such as the fingertip F touching the monitor 2 is slid in the right direction, the waveform chart displayed on the monitor 2 is also scrolled in the right direction following this, but temporarily scrolls too much. When the fingertip F is returned in the reverse direction, that is, in the left direction, the waveform chart scrolls in the left direction following this operation.

  Apart from the follow-up scroll, the waveform chart can also be scrolled by fast-forwarding. This fast-forward scroll is executed by an operation of an operator's fingertip F or the like. For example, as described above, in order for the operator to display the desired waveform position on the monitor 2, the command means such as the fingertip F is moved to the left and right to scroll the waveform chart displayed on the monitor 2 to the left and right. When the waveform portion does not appear on the monitor 2, it is preferable to scroll the background chart of the display on the monitor 2 by fast-forwarding by using a command means such as the fingertip F as a trigger.

  As an example of the trigger for executing the fast-forward scroll, when the command means such as the fingertip F touching the monitor 2 is quickly moved on the monitor 2, or immediately before the command means such as the fingertip F is separated from the monitor 2, the monitor 2 is quickly paid. The case where operation was performed can be mentioned. The operation for quickly paying off the monitor 2 is, for example, when the desired waveform portion does not appear on the monitor 2 even if the monitor 2 is moved left and right with the fingertip F and the waveform chart displayed on the monitor 2 is scrolled to the left and right. In addition, by performing an operation of paying with the fingertip F in the direction in which the fast-forward scroll is desired, the tracking scroll can be switched to the fast-forward scroll. The speed of the fast-forward scroll is relatively fast when the command means is moved quickly according to the speed of the command means such as the fingertip F, and relatively fast when the means is moved relatively slowly. It is better to scroll forward at low speed.

  Of course, the speed of the fast-forward scroll may be constant without depending on the moving speed of the command means. Then, after the fast-forward scroll is executed, the fast-forward scroll may be stopped by an operation such as touching the monitor 2 once with the fingertip F or touching it several times intermittently.

  That is, according to the type of operation of the command means such as the fingertip F using the touch panel 222, the monitor 2 is operated in the same manner as the roll-drawn waveform chart paper is pulled out, rewound, further pulled out at once, or rewound at once. A follow-up scroll that executes scrolling in accordance with the movement operation of the fingertip F on the monitor 2 in order to scroll the waveform chart and stop scrolling of the waveform chart displayed on the monitor 2, and the fingertip F etc. The past measurement data of the waveform observation apparatus 1 in which a huge amount of measurement data is accumulated by using differently the fast-forward scroll that executes scrolling at a high speed even if it is separated from the monitor 2 depending on the operation of the command means such as the fingertip F Can be displayed on the monitor 2 quickly and accurately as intended by the operator. The proper use of the scroll mode due to differences in the operation of the command unit, capable of handling waveforms chart of the display in the same sense on the monitor 2 with the conventional operation or rewinding or pull the roll winding waveform chart paper.

  FIG. 6 is a flowchart illustrating an example of scroll control based on a command from the fingertip F or the like that touches the touch panel 222. The start of step S100 shown in FIG. 6 is executed so that the following flow is always confirmed at a constant interval such as 50 msec when the waveform observation apparatus 1 is powered on.

  When the start of step S100 is started, whether or not the waveform chart display area 41 of the touch panel 222 has been touched is confirmed by a signal from the touch panel 222 in step S101. This step S101 constitutes monitoring means for periodically monitoring that the waveform chart display area 41 is touched. If it is determined in step S101 that the touch is made, the process proceeds to step S102 because of “YES”, and the touch position (P) on the touch panel 222 is recognized. This touch position (P) is shown in FIG. The position data is stored in the memory 30 arranged on the main board. More specifically, the position (P) on the touch panel 222 is two-dimensional coordinate data composed of the X coordinate value and the Y coordinate value given to the touch panel 222, and is the coordinate touched by the fingertip F of the operator. is there. The flow when it is determined in step S101 that the waveform chart display area 41 of the touch panel 222 has not been touched will be described later.

  In step S 102, the position (P) on the touch panel 222 is recognized, and the position data is stored in the memory 30. That is, the memory 30 constitutes a storage unit that stores the touch position. Then, in the next step S103, it is determined whether or not the flag I is “I = 0” or “I = 1”. The meaning of the flag I here indicates whether or not the touch panel has already been touched in the previous flow. If the touch on the touch panel has been confirmed in the previous flow, the flag I is set to “I = When the touch is not confirmed, the flag I is in a state indicating “I = 0”. For this reason, if the flag I is in a state indicating “I = 1” in step S103, it is determined that the previous touch has been recognized, and the process proceeds to the next step S104.

  In step S104, the previously touched position (O) is compared with the currently touched position (P) to determine whether there is a change in the position. In this step, by comparing the position touched last time with the position touched this time, whether or not the touch action of the command means such as the fingertip F of the operator is simply touching the touch panel 222 By moving the fingertip F to be touched, it is determined whether or not the operator intends to scroll the waveform chart displayed on the monitor 2.

  More specifically, the position (O) on the touch panel 222 in the previous flow stored in the memory 30 in step S102 and the position (P) on the touch panel 222 in the current flow stored in the memory 30. ) Is compared by the microcomputer 29 as the control means. More specifically, in determining whether there is a change in the touch position between the previous time and the current time, an error in position data on the touch panel or a change in the touch position that cannot be determined until the movement on the touch panel 222 intended for scrolling is performed. In order to determine that there is no change in the touch position, a threshold is set for the change in the touch position, and a change in the touch position of a predetermined amount or more is determined as “there is a change in the touch position”. preferable. If it is determined that there is no change in the touch position between the previous time (O) and the current time (P), the flow proceeds from step 104 to step S108, which will be described later, and the previous touch stored in the memory 30. This flow is terminated after the rewriting of the current touch position (P) is performed on the position (O).

  If it is determined in step S104 that there is a change in the touch position between the previous (O) and current (P), the process proceeds to the next step S105. In step S105, the scroll amount and direction on the touch panel 222 are calculated based on the previous touch position (O) and the current touch position (P) stored in the memory 30. This step S105 constitutes a moving speed and moving direction calculation means in the follow-up scroll function.

  Note that the calculated direction means a direction in which the waveform chart is scrolled on the monitor 2. For example, when the scroll direction is scrolled only in the X direction indicating the time series direction of the waveform, the scroll amount corresponding to the direction is scrolled. Is calculated. At this time, it may be calculated from the movement distance on the two-dimensional coordinate between the previous touch position (O) and the current touch position (P). If the scroll direction is one-dimensional (time axis direction), It is desirable to calculate the scroll amount based on the movement distance corresponding to the one-dimensional direction. On the other hand, when scrolling is possible in the two-dimensional direction, each of the X direction and the Y direction is based on the movement distance on the two-dimensional coordinate between the previous touch position (O) and the current touch position (P). The scroll amount may be calculated evenly, or if the scroll is performed with more faithful reproduction of the operator's intention, the movement amount in the X direction and the Y direction is calculated respectively, and based on the movement amount in each direction, A scroll amount in each direction may be calculated.

  Based on the calculated value, prior to scrolling the waveform chart displayed in the waveform chart display area 41 of the monitor 2, in the next step S106, it is determined whether or not the range is scrollable. For the latest part and the oldest part of the stored data, a zone is set in the time-series direction, and it is determined whether or not the currently displayed waveform part is located in this zone. If a waveform portion that is not located in this zone is displayed, a waveform chart is displayed following the movement of the fingertip F, which will be described later, in the next step S107 based on the value calculated in step S105. Follow-up scrolling is performed.

  On the other hand, if it is determined that there is a waveform that is currently displayed in the above-described zone, the process proceeds to step S110, the scrollable range is limited, and the following scroll is executed in the next step S107. . The follow-up scroll here is a process that conceptually is a process of moving, that is, scrolling, by causing the monitor 2 to follow the waveform chart displayed on the movement of the command means such as the fingertip F that moves on the touch panel 222. Then, it means a function in which the waveform chart follows and scrolls at almost the same speed as the moving direction and the moving speed of the fingertip F.

  More specifically, in step S110, for example, when the waveform part currently displayed in the waveform chart display area 41 is the waveform of the most recent part stored in the memory 30, and the scroll direction of the operator If the fingertip F is further moved toward the latest waveform display direction, the latest waveform portion is positioned at the right end of the waveform chart display region 41, assuming that the right side of the waveform chart display region 41 displays the latest waveform. The range that can be scrolled is limited. On the other hand, when the waveform part currently displayed in the waveform chart display area 41 is the waveform of the oldest part stored in the memory 30 and the movement of the fingertip F of the operator is even older. If the right side of the waveform chart display area 41 displays the latest waveform portion, the oldest waveform can be scrolled at the right end of the waveform chart display area 41. Limit the range.

  When the execution of the tracking scroll is completed in step S107, in step S108, the current touch position (P) is rewritten with respect to the previous touch position (O) stored in the memory 30, and the storage is updated. Proceeding to step S109, this flow ends.

  Next, the case where the flag flag I is not “I = 1”, that is, “I = 0” in step S103 described above will be described. In this case, the process proceeds to step S111, and it is determined whether or not the fast-forward scroll described later is currently being performed. If it is determined that the fast-forward scroll is being performed, it is determined that the touch action this time is a touch action corresponding to a signal for stopping the fast-forward scroll, and the fast-forward scroll is stopped in the next step S112. On the other hand, if it is determined in step S111 that fast-forward scrolling is not currently being performed, the current touch action is recognized as the first touch action as a trigger action for the above-described "following scroll" or "fast-forward scroll" described later. Therefore, in step S113, the touched position (P) is stored in the storage position in the memory 30 that stores the previous touch position (O), and the initial touch position (S) is stored in the memory 30. Store in memory location.

  In the present embodiment, after stopping fast-forward scrolling in step S112, the position touched in step S113 (P) is changed to the storage position in the memory 30 that stores the previous touch position (O). It memorize | stores in the memory | storage position in the memory 30 which memorize | stores the first time touch position (S). The purpose of this example is to improve the convenience of the touch action by combining the touch of the act of stopping the fast-forward scroll and the touch that becomes the start trigger of the next new fast-forward scroll or the follow-up scroll in the same action. This is to make it happen. Therefore, when such a function for improving convenience is unnecessary, after stopping the fast-forward scroll in step S112, the flow is connected to step S109 via step S115 described later, and the flow is terminated. May be.

  Next, in step S113, after the position (P) touched this time is stored in the storage position in the memory 30 that stores the previous touch position (O), the process proceeds to step S114, and the touch period (W) is measured. In order to do this, the measurement timer 42 (FIG. 4) is started. The value of the timer 42 here is used in step S118 of fast-forward scroll described later. Then, the process proceeds to step S115, the value of flag I is changed to “I = 1”, the process proceeds to step S109, and the flow ends.

  Next, a flow when it is determined in step S101 described above that the waveform chart display area 41 of the touch panel 222 is not touched, particularly a fast-forward scroll execution flow will be described.

  If it is determined in step S101 that the waveform chart display area 41 of the touch panel 222 has not been touched, the process proceeds to step S116. In step S116, it is determined whether or not the value of the flag I described above is “I = 1”. If it is determined in this determination that the value of the flag I is not “I = 1”, that is, “I = 0”, it means that the touch action on the touch panel has not been performed in the previous main flow. In other words, the action for “following scroll” or “fast-forward scroll” is not performed, and the flow proceeds to step S109, and this flow ends.

  On the other hand, if it is determined in step S116 that the value of the flag I is “I = 1”, the touch action on the touch panel was performed in the previous flow, and the touch action is continued in the current flow. In step S117, the measurement timer 42 that has already been activated and counting is stopped, and the touch period (W) that is the time from the start of touch to the end of touch is determined.

  In step S118, the previous touch position (O) and the initial touch position (S) stored in the memory 30 are read, and the touch during the touch period is calculated from the touch period (W) calculated in step S117. The moving speed and direction of the position are calculated. That is, step S117 constitutes a moving distance and direction calculating means in the fast-forward scroll, starting from the time when the operator starts moving by touching the fingertip F on the monitor 2, that is, the touch panel 222, and moving on the touch panel 222. After that, when the fingertip F is released from the touch panel 222 as an end point, the moving speed is calculated and the moving direction is calculated based on the moving distance and time from the starting point to the end point.

  In the next step S119, the fingertip immediately before the operator releases the fingertip F from the touch panel 222 by comparing the moving speed of the touch position during the touch period calculated in S118 with a threshold for a predetermined moving speed. It is determined whether or not the operation of F is a request for fast-forward scroll, and fast-forward scroll limiting means for permitting or prohibiting execution of fast-forward scroll is configured. That is, in this embodiment, on the waveform chart display area 41 of the touch panel 222, the position where the touch is started and the position where the touch is ended, that is, the position where the touch is stopped (the position here is given to the touch panel). If the movement speed of the touch position calculated by the distance (which means the position in the coordinated position) and the time required to move this distance is faster than a predetermined threshold, the operator performs fast-forward scrolling. Determine what you want. On the other hand, if the moving speed of the touch position is slower than the threshold value, it is determined that the operator does not desire fast-forward scrolling.

  For this reason, if it is determined in step S119 that the moving speed of the touch position is faster than the threshold value, fast-forward scrolling is started in the next step S120, and then the process proceeds to step S121, where the flag I is cleared, The value becomes “I = 0”, and then the flow proceeds to step S109 and the flow ends.

  On the other hand, if it is determined in step S119 that the moving speed of the touch position is slower than the threshold value, fast-forward scrolling is not executed, the flow proceeds to step S121, flag I is cleared, and the value becomes 0. Thereafter, the flow proceeds to step S109, and this flow ends.

  The first embodiment related to the present invention has been described above. This first embodiment is linked to and follows the action of moving the monitor 2 while touching it with the fingertip F or the like as a screen scroll function by a touch action. The operator moves the fingertip F and the like from the monitor 2 according to the following scroll for scrolling the waveform chart displayed on the monitor 2 and the moving distance and moving time from the first touch action until the command means such as the fingertip F moves away from the monitor 2. After the release, a fast-forward scroll function is provided in which the waveform chart is automatically scrolled at a predetermined speed in the direction in which the operator moves the command means such as the fingertip F on the monitor 2. The fast-forward scroll may be a constant speed defined in advance, or, as will be described later, from the time when the monitor 2 is touched and the movement of the fingertip F or the like is started (starting point) from the monitor 2 to the fingertip F or the like. You may make it scroll at the speed | rate corresponding to the moving speed of the fingertip F to the time of releasing (end point). That is, if the moving speed of the command means such as the fingertip F is fast, the waveform chart displayed on the monitor 2 is scrolled at a relatively high speed. If the moving speed of the command means such as the fingertip F is relatively slow, the speed is relatively slow. It is preferable to scroll.

  More specifically, in this embodiment, when the touch panel is touched and the movement is started, the waveform chart displayed on the monitor 2 is moved in the same direction as the movement of the command means such as the fingertip F until the touch is stopped. When scrolling at the same speed and the operator stops touching the monitor 2, if the speed calculated by the distance touched so far and the time taken is greater than the threshold, this time the screen is displayed by the fast-forward scroll function. Will scroll at a relatively fast rate. The fast-forward scrolling is stopped when the operator touches the monitor 2. The scroll speed in the fast-forward scroll function may be a constant speed, but the time from when the fingertip F touched to the monitor 2 starts to move to the time when the fingertip F is released from the monitor 2; It is obtained based on the moving speed of the command means such as the fingertip F calculated from the distance traveled by the command means such as the fingertip F on the monitor 2, and thereby fast-forward scrolling is executed at a speed corresponding to the moving speed of the fingertip F Is done.

  In other words, stepwise, linear, or another correction factor may be applied, but the moving speed of the command means such as the fingertip F is determined as the scroll speed obtained in the fast-forward scroll by the operator, and fast-forwarding is performed based on the moving speed of the command means. It is preferable to control the scroll speed in the scroll function. After the fast-forward scroll function is executed, the monitor 2 is stored in the designated scroll direction except that the scroll stop function in step S112 described above, that is, the fast-forward scroll is stopped by touching the fingertip F to the monitor 2. Scrolling at the same speed to the end of the waveform data (in other words, looking at the stored waveform in time series and storing the oldest waveform end or the newest waveform end) It has become. That is, the fast-forward scroll speed executed at a speed corresponding to the moving speed of the command means such as the fingertip F is maintained from the start point to the stop point of the fast-forward scroll.

  Next, a second embodiment of the present invention shown in FIG. 7 will be described. FIG. 7 is a flowchart illustrating an example of scroll control as a second embodiment based on a command from the fingertip F or the like that touches the touch panel 222.

  The start of step S100 shown in FIG. 7 is executed so that the following flow is always confirmed at regular intervals such as 20 msec when the waveform observation apparatus 1 is powered on. As will be apparent from the contents to be described later, the flow execution interval in the second embodiment is the scroll speed in the fast-forward scroll function, paying attention to the moving speed of the command means on the touch panel immediately before the command means such as the fingertip F is separated from the touch panel. Therefore, it is preferable to execute the flow at a shorter time interval than in the first embodiment described above.

  Further, steps S200, S201, S202, S203, S204, S205, S206, S207 and S213 in FIG. 7 are the same as S100, S101, S102, S103, S104, S105, S106, S107 and S110 in the first embodiment. Since it is the same content, description is abbreviate | omitted. That is, in the previous and current flows, it is confirmed that the waveform chart display area 41 of the touch panel 222 has been touched, and if it is determined that the touch position has changed, the follow-up scroll function is executed.

  Specifically, like step S107 in the first embodiment, follow-up scrolling is executed in step S207 in the second embodiment.

  Thereafter, the step proceeds to step S208, and the number of monitoring times is incremented (C = C + 1). The number of times of monitoring here can be rephrased as the number of times of execution of this control flow when the touch action is continuously performed after the first touch on the monitor 2, that is, the touch panel 222 is confirmed. For this reason, in step S208, 1 for the current flow execution is added to the cumulative number of executions corresponding to the previous flow.

  In step S208, when the increment of the continuous number of monitoring is completed, the step proceeds to step S209. Here, the threshold M for the predetermined continuous monitoring number is compared with the latest accumulated monitoring number C incremented in step S208. If it is determined that the latest accumulated monitoring count C incremented in step S208 is smaller or the same as the threshold M for the predetermined continuous monitoring count, “NO” is set. Then, a step progresses to step S210. On the other hand, if it is determined that the latest cumulative monitoring number C incremented in step S208 is larger than the threshold M for the predetermined continuous monitoring number, “YES” is determined. Then, the process proceeds to step S211.

  The specific value of the threshold value M set in step S209 is set based on the following concept. In the second embodiment, in order to control the scroll speed in the fast-forward scroll function by paying attention to the moving speed of the command means on the touch panel 222 immediately before the command means such as the fingertip F is separated from the monitor 2, that is, the touch panel 222, basically Is the movement distance between the previous position on the touch panel 222 and the previous position on the touch panel 222 with respect to the flow in which it can be confirmed that the command means such as the fingertip F is separated from the touch panel 222, and the movement time (this movement) The time can be calculated from the time interval between one flow execution and the next flow execution.) If calculated, the movement speed immediately before the command means such as the fingertip F leaves the touch panel 222 is theoretically calculated. I can grasp it.

  That is, it is theoretically sufficient if the threshold value M is at least “M = 2”. However, on the other hand, for example, if the execution of this flow is executed at a short time interval such as 20 msec in order to more accurately grasp the timing at which the command unit leaves the touch panel 222, the command unit such as the fingertip F is separated from the touch panel 222. The operation of the human fingertip F is specifically grasped only by the movement distance between the previous position on the touch panel 222 and the previous position on the touch panel 222 with respect to the confirmed flow, and the movement time required for the movement. It may be difficult to do. For this reason, the threshold value M in the present embodiment basically includes position data on the touch panel 222 of the previous time and the previous time with respect to the flow in which it is confirmed that the command means such as the fingertip F is separated from the touch panel 222. It is preferable that the number of flows can store the past position data on the touch panel 222 included in about 1 second that goes back to. Specifically, if the time interval between one flow execution and the next lower flow execution is 20 msec, the number of flows in “one second” is 50 times. Of course, it goes without saying that the number of times varies depending on the time interval between one flow and the next flow in this embodiment and the time to be stored retroactively.

  For this reason, in step S210 and step S211 to be described later, the number of data that can be stored in the memory 30 that stores the latest position data and past data is equal to the number of threshold values M described above. The storage locations are arranged in the order of old or new data, and each storage location is assigned an address number corresponding to the threshold value M from address “1”. More specifically, the memory 30 in the present embodiment is preferably a ring buffer type memory, and is preferably a memory in which the number of storage positions is provided corresponding to the threshold value M.

  Next, step S210 will be described. In step S210, since the latest cumulative number C is smaller than or equal to the threshold value M, the latest touch position data is stored in the storage position corresponding to the cumulative number C. Then, after the storage operation in step S210 is completed, the flow proceeds to step S212, and the flow ends.

  Next, step S211 will be described. In this step S211, when the latest cumulative number C is larger than the threshold value M, the latest touch position is stored in the storage position of the memory 30 corresponding to the value obtained by subtracting the threshold value M from the latest cumulative number C. Data is stored by being overwritten. Then, after completion of the storage operation in step S211, the process proceeds to step S212 and the flow ends.

  Next, the case where “NO” in step S203 described above, that is, the flag flag I is not “I = 1”, in other words, “I = 0” will be described. In this case, the process proceeds to step S214, and it is determined whether or not a fast-forward scroll described later is currently being performed. If it is determined that the fast-forward scroll is being performed, it is determined that the current touch action is a touch action corresponding to a command for stopping the fast-forward scroll, and the fast-forward scroll is stopped in the next step S215.

  On the other hand, if it is determined in step S214 that fast-forward scrolling is not currently being executed, the current touch action is recognized as the first touch action as a trigger action for the above-described “following scroll” or “fast-forward scroll” described later. Therefore, in step S216, the touched position (P) is stored in the storage position in the memory 30 to which the address “1” is assigned.

  Further, in this embodiment, after stopping the fast-forward scroll in step S215, the touched position (P) in step S216 is changed to the storage position in the memory 30 to which the address “1” is assigned. Remember. In this embodiment, the touched position (P) is stored in the storage position in the memory 30 to which the address “1” is assigned by using the ring buffer memory described above.

  The purpose of this example is to improve the convenience of the touch action by combining the touch of the act of stopping the fast-forward scroll and the touch that becomes the start trigger of the next new fast-forward scroll or the follow-up scroll in the same action. This is to make it happen.

  Therefore, if such a function for improving convenience is unnecessary, after stopping the fast-forward scroll in step S215, the flow is connected to step S212 via step S217 and step S218 described later. May be terminated.

  Next, in step S216, after the touched position (P) is stored in the storage position in the memory 30 to which the address “1” is assigned, the process proceeds to step S217, and the value of the flag I is set to “I = 1 ”, and the process further proceeds to step S218 to initialize the number of monitoring times C, that is, set the value to“ C = 0 ”, and then proceed to step S212 to end the flow.

  If it is determined in step S201 that the waveform chart display area 41 of the touch panel 222 has not been touched, the process proceeds to step S219. In step S219, it is determined whether or not the value of the flag I described above is “I = 1”. In this determination, if it is determined that the value of the flag I is not “I = 1”, that is, “I = 0”, the touch action on the touch panel is not performed in the previous main flow. The action for “following scroll” or “fast-forward scroll” has not been performed, and the flow proceeds to step S212, and this flow ends.

  On the other hand, if it is determined in step S219 that the value of the flag I is “I = 1”, “YES”, that is, the touch action on the touch panel was performed in the previous flow. It is determined that the action is not continued, and the process proceeds to step S220.

  In step S220, the past touch position including the previous touch position (O) and the previous touch position (S) stored in the memory 30 is read, and the time interval between the execution of one flow and the next flow is determined. And the monitoring frequency C, and based on this, the touch position moving speed for the data stored in the memory 30, that is, the command means such as the fingertip F on the touch panel 222 immediately before the command means such as the fingertip F leaves the touch panel. The moving speed and direction of the are calculated. This step S220 constitutes the moving speed and direction calculating means in the second embodiment.

  Next, in step S221, the moving speed of the command means on the touch panel 222 just before the command means such as the fingertip F is calculated from the touch panel 222 calculated in S220 is compared with a threshold for a predetermined moving speed. Thus, it is determined whether or not the operation of the fingertip F of the operator desires fast-forward scrolling, and fast-forward scroll limiting means for permitting or prohibiting execution of fast-forward scroll is configured. That is, in the present embodiment, on the waveform chart display area 41 of the touch panel 222, the moving distance of the command means such as the fingertip F on the touch panel 222 immediately before the command means such as the fingertip F is separated from the touch panel 222, and the distance If the movement speed of the touch position calculated by the time taken for the movement is relatively faster than the threshold value, it is determined that the operator desires fast-forward scrolling. Conversely, if the moving speed of the touch position is relatively slower than the threshold value, it is determined that the operator does not desire fast-forward scrolling.

  For this reason, when it is determined in step S221 that the moving speed of the touch position is faster than the threshold value, “YES” means that fast-forward scrolling is started in the next step S222, and then the process proceeds to step S223. The flag I is cleared and the value becomes “I = 0”. Thereafter, the flow proceeds to step S212, and this flow ends.

  On the other hand, if it is determined in step S221 that the movement speed of the touch position is slower than the threshold value, “NO” means that the fast-forward scroll is not executed, and the flow proceeds to step S223, and the flag I is cleared. Then, the value becomes “I = 0”, and then the flow proceeds to step S212, and this flow ends.

  As described above, the second embodiment related to the present invention has been described. In this embodiment, as a screen scroll function by a touch action, the monitor 2 is displayed on the monitor 2 in conjunction with the action of continuously moving the monitor 2 with the fingertip F or the like. The operator monitors the command means such as the fingertip F by the following scroll function in which the waveform chart is scrolled in conjunction with the operation speed of the fingertip F calculated by the moving distance and moving time immediately before the fingertip F is released from the monitor. 2 is provided with a fast-forward scroll function that is automatically scrolled at a predetermined speed in the direction of movement on 2.

  More specifically, in this embodiment, when the touch panel is touched and the movement is started, the waveform chart displayed on the monitor 2 scrolls following the movement of the fingertip F or the like by the follow scroll function until the touch is stopped, Next, when the movement speed of the command means on the touch panel immediately before the command means such as the fingertip F is removed from the monitor 2 when the touch is stopped, for example, an operation of quickly paying the fingertip F on the monitor 2 is involved. When the fingertip F is separated from the monitor 2 from the monitor 2, the tracking scroll is switched to the fast-forward scroll, and the waveform chart displayed on the monitor 2 is quickly scrolled. Furthermore, the scroll speed in the fast-forward scroll function is obtained based on the moving speed of the command means on the touch panel 222 immediately before the command means such as the fingertip F is separated from the monitor 2. When the fingertip F is moved relatively slowly, the scrolling is performed at a relatively low speed.

  That is, stepwise, linear, or another correction coefficient may be applied, but the moving speed immediately before the command means such as the fingertip F leaves the monitor 2, that is, the touch panel 222, that is, the operation speed of the fingertip F, for example, is fast-forwarded by the operator. The scroll speed determined in the scroll is determined, and the scroll speed in the fast-forward scroll function is controlled based on the speed of the fingertip F paying operation. After the fast-forward scroll function is executed, the monitor 2 is stored in the designated scroll direction except for the scroll stop function in step S215 described above by touching the monitor 2 with command means such as the fingertip F. Scrolling at the same speed to the end of the waveform data (in other words, looking at the stored waveform in time series, the oldest waveform end or the newest waveform end stored) ing.

  The embodiment has been described above by taking the horizontal display mode in which the time axis of the waveform chart is displayed in the horizontal direction as an example. However, as illustrated in FIG. However, it goes without saying that the follow-up scroll and the fast-forward scroll may be executed by the operation of the operator's fingertip F or the like.

  Further, as shown in FIG. 9, the monitor 2 has an enlarged display area 45 for enlarging and displaying a waveform chart and a reduced long-time display area 46 for reducing and displaying a relatively long-time waveform chart. When the portion surrounded by the frame 47 of the long-time display area 46 is displayed in the enlarged display area 45, both the enlarged display area 45 and the reduced long-time display area 46 follow the scrolling by the operation with the fingertip F etc. of the operator described above. It is recommended to perform fast-forward scrolling.

  Further, as shown in FIG. 10, the monitor 2 is divided into two to prepare first and second waveform chart display areas 41A and 41B, and the waveform chart is monitored independently for each of the display areas 41A and 41B. In the case where the waveforms can be compared by displaying in 2, it is preferable to execute the following scroll and the fast-forward scroll in the display areas 41 </ b> A and 41 </ b> B independently by the operation of the operator's fingertip F or the like.

  In addition, as shown by the solid line and the broken line in FIG. 11, when two waveform charts are superimposed on the monitor 2 and the lower waveform chart can be compared through the waveform chart positioned above, The following scroll and fast-forward scroll may be executed by the operation of the operator's fingertip F or the like with respect to the displayed waveform chart (solid line).
