Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display operation device such as a fire alarm system that operates a switch using a touch panel provided on a display screen.

[0002]

[Prior Art]

 Conventionally, as a display operation device using a touch panel used in, for example, a fire alarm system, one shown in FIG. 3 is known. In FIG. 3, reference numeral 1 is a CRT display device, and a transparent touch panel 3 is provided on a CRT screen 2. On the CRT screen 2, switch images to be operated are displayed as, for example, "switch 1" and "switch 2".

Here, the CRT display device 1 receives the image data from the arithmetic processing unit 4 using a microprocessor (MPU) or the like, and is controlled by the CRT controller 5. The touch panel 3 is controlled by a dedicated touch panel controller 6. If the touch panel 3 is touched with a fingertip or the like to operate the "switch 1", the coordinate value (x, y) of the touch position is detected by the touch panel 3 and output from the touch panel controller 6 to the arithmetic processing unit 4.

The arithmetic processing unit 4 has coordinates a (x1, y1) and b (x2, y2) of the points a and b of the “switch 1” as reference values for area determination, and x1 ≦ x ≦ x2 If y1 ≧ y ≧ y2, it is determined that the “switch 1” is operated.

Similarly, the “switch 2” also has coordinates c (x3, y3) and d (x 4, y4) of the points c and d as reference values for area determination, and x3 ≦ x ≦ x4 and y3 If ≧ y ≧ y4, it is determined that the “switch 2” is operated.

When the operation of the “switch 1” is determined, the display “switch 1” on the CRT screen 2 is highlighted and the operator is informed that the switch has been pressed. At the same time, the arithmetic processing unit 4 performs processing corresponding to the switch operation. For example, a transmission device 7 is connected to the arithmetic processing device 4, and a control device such as a bell 10 and a damper 11 is connected to a transmission line 8 drawn from the transmission device 7 via a repeater 9.

For example, if the “switch 1” is the “single ringing switch” of the bell 10, the arithmetic processing unit 4 that determines the operation of the “switch 1” is relayed by connecting the bell 10 via the transmission device 7. The bell 9 is instructed to the device 9, and the bell 10 is simultaneously ringed.

[0008]

[Problems to be solved by the device]

 However, in the conventional display operation device using such a touch panel, the switch operation is performed only by lightly touching the touch panel on the CRT screen with insects or clothes, and when cleaning the panel surface. However, there is a problem that the switch is operated.

Therefore, as shown in FIG. 4, a mechanical switch 12 is provided separately, and even if the switch operation of the touch panel 3 is determined by the arithmetic processing unit 4, the processing corresponding to the switch operation is not immediately performed, and the mechanical switch 12 is not performed. When is operated, switch processing such as ringing of the bell 10 based on the switch operation of the touch panel 3 is performed again. However, when the mechanical switch 12 is provided, the switch operation is complicated because both the switch operation of the touch panel 3 and the switch operation of the mechanical switch 12 are required. The additional provision of the mechanical switch 12 is also a constraint on the design configuration.

The display operation device using such a touch panel is not limited to the fire alarm system, and is the same as the entry / exit display system using the touch panel shown in FIG. 5, for example. In FIG. 5, reference numeral 13 denotes a display operation device, which is provided with a touch panel 3 on the CRT screen 2, and the CRT screen 2 displays display units 1 to 5 and corresponding switches SW1 to SW5. There is. Further, a mechanical execution switch 14 is provided. A display device 15 is connected to the display operation device 13 at a different position, and a display lamp 16 is provided on the display device 15 to indicate the presence or absence of the person corresponding to the names of persons 1 to 5. ing.

The usage of this attendance display system is the same as in the case of FIG. 3 and FIG. 4, for example, if the switch “SW2” corresponding to “Display 2” on the touch panel 3 is pressed when the second person comes to work. Then, the operation of the touch panel 3 is determined, and the switch display of "SW2" is reversed. Then, when the execution switch 14 is pressed, the "display 2" corresponding to the "SW2" is displayed as a lighting state, and at the same time, the indicator lamp 16 corresponding to No. 2 of the display device 15 is turned on.

However, even when the execution switch 14 is provided, the switch operation is complicated because the switch operation of the touch panel and the switch operation of the mechanical switch are required, and the mechanical switch other than the touch panel is required. The additional provision of “” is also a constraint on the design structure. The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a display operation device capable of distinguishing between switch operation and mere contact by determining the force of pressing the switch. To aim.

[0013]

[Means for Solving the Problems]

 In order to achieve this object, the present invention is configured as follows. The symbols in the drawings of the examples are also shown. That is, the display operation device of the present invention is provided on the display screen 2 of the display device 1, and is a touch panel device (composed of the touch panel 20 and the touch panel controller 21) that detects and outputs the coordinates of the touch position of a fingertip or the like and the pressure at the time of touch. ) And the coordinate information (x, y) output from the touch panel device with a preset switch region to determine the switch operation, and the pressure information (z) output from the touch panel device. From the pressure determination unit 23 that determines that the pressure has been pressed with a predetermined value or more, and the switch processing unit that performs the corresponding switch processing when the determination outputs of both the region determination unit 22 and the pressure determination unit 23 are obtained. 24 is provided.

[0014]

[Action]

 According to the display operation device of the present invention having such a configuration, even if an object touches the touch panel lightly and coordinate data of the touch position is output, if the pressure due to the touch is smaller than the predetermined value, it is based on the switch operation. No processing is performed, and the processing based on the switch operation is performed only when the pressure on the touch panel is strongly pressed and the pressure equal to or higher than the predetermined value is obtained.

Therefore, it is possible to prevent erroneous switch operations from being performed even if insects or clothes touch the touch panel, or the panel surface is cleaned, and it is not necessary to provide a separate mechanical switch. There are no restrictions on the design structure.

【Example】

 FIG. 1 is a block diagram of an embodiment of a display operation device of the present invention for a fire alarm system. In FIG. 1, reference numeral 1 is a CRT display device, which has a CRT screen 2, and displays image data received from the arithmetic processing device 4 side by a CRT controller 5. In this embodiment, the CRT controller 5 displays the character and image of "switch 1" and the character and image of "switch 2" on the CRT screen 2.

A touch panel 20 is installed on the front surface of the CRT screen 2. The touch panel 20 is driven by the touch panel controller 21, and in addition to the coordinates (x, y) of the touch position, the touch panel 20 used in the present invention can detect the pressure (z) pressing the touch panel. As the touch panel 20 that can detect the pressure (z) in addition to the position coordinates (x, y), for example, a touch panel using surface acoustic waves, that is, SAW (Surface Acoustic Wave) can be used.

The touch panel 20 using the SAW technology has a structure in which the SAW obtained by applying the oscillation pulse to the transmitting transducer is propagated to the panel surface and the SAW reflected and returned by the reflection array is received. With. When touching the panel surface with a finger or the like, the phenomenon of absorption of the propagating SAW occurs and the level of the received signal decreases, so a touch is detected. That is, the coordinate position can be detected. The SAW wave is propagated individually in the x-axis direction and the y-axis direction, and the x-coordinate and the y-coordinate of the touch position can be detected respectively.

Further, the pressure z can be detected by how much the signal is attenuated at the touch position. That is, the amount of SAW wave attenuation at the touch position is related to the contact area. Therefore, when the panel surface is pressed with a soft substance such as a finger, the size of the contact area is proportional to the touch pressure. Therefore, the pressure z can be detected from the level change when the touch is generated.

The touch panel controller 21 detects the touch coordinates (x, y) and the pressure value (z) associated with the touch operation on the touch panel 20. That is, the touch panel controller 21 performs transmission control of the transmission transducer provided on the touch panel 20, reception of a reception signal from the reception transducer, and signal processing for detecting the coordinate position and pressure.

The coordinates (x, y) and pressure (z) of the touch position on the touch panel 20 detected by the touch panel controller 21 are provided to the arithmetic processing unit 4. The arithmetic processing unit 4 is provided with a region determination unit 22, a pressure determination unit 23, and a switch processing unit 24, and the functions of these units are realized by executing a control program. The area determination unit 22 compares the touch coordinates (x 1, y) obtained from the touch panel controller 21 with the coordinate positions of the “switch 1” and “switch 2” on the touch panel 20 of the CRT screen 2 stored in advance.

That is, for the “switch 1”, the coordinates (x 1, y 1) of the point a in the upper left corner of the switch image and the coordinates (x 2, y 2) of the point b in the lower right corner are stored. Similarly, for the "switch 2", the coordinates (x3, y3) of the point c in the upper left corner and the coordinates (x4, y4) of the point d in the lower right corner are stored. If x1 ≦ x ≦ x2 and y1 ≧ y ≧ y2 with respect to the touch coordinates (x, y) from the touch panel controller, it is determined that the switch 1 has been operated. If x3 ≦ x ≦ x4 and y3 ≧ y ≧ y4, it is determined that the switch 2 has been operated.

The pressure determination unit 23 compares the pressure (z) accompanying the touch operation of the touch panel 20 detected by the touch panel controller with a predetermined value, and the switch operation is performed when the pressure z equal to or higher than the predetermined value is obtained. Judge as something. The outputs of the region determination unit 22 and the pressure determination unit 23 are given to the switch processing unit 24, and the determination output from the region determination unit 22 recognizes whether "switch 1" or "switch 2" has been operated, and at the same time, It is determined from the determination output of the pressure determination unit 23 that the switch operation has been performed due to the strong pressing of the panel, and the processing associated with the switch operation is performed based on both determination outputs.

For example, when the ringing of the bell 10 connected via the transmission device 7 and the transmission line 8 and the repeater 9 is set as the operation item of the “switch 1”, the switch The processing unit 24 commands the repeater 9 to ring the bell via the transmission device 7, and the bells 10 are ringing at the same time. FIG. 2 is a block diagram of an embodiment of a display operation device of the present invention intended for an exit / entry display system.

In FIG. 2, reference numeral 13 is a display operation device, and a pressure detection type touch panel 20 is provided on the front surface of the CRT screen 2. In the portion of the CRT screen 2 on which the touch panel 20 is provided, "display 1" to "display 5" and a rectangular display frame are provided. Further, the display device 15 is provided with an indicator light 16 for indicating the names of persons 1 to 5 and the presence or absence of going out.

The configuration of the display operation device 13 is the same as that of the display operation device 13 except for the transmission device 7 and the subsequent components. In the embodiment of FIG. 2, the display device 15 is connected instead of the transmission device 7 and thereafter. The operation of the embodiment shown in FIG. 2 is as follows. Now, assuming that the second person comes to work, touch "display 2" on the touch panel 20 with a certain strength or more. The display operation device 13 detects that the “display 2” has been surely pressed by the coordinate value and the pressure value sent from the touch panel 20, and switches the rectangular display frame corresponding to the “display 2” to the lit display. Instead, the indicator lamp 16 corresponding to the second display device 15 is turned on at the same time. Therefore, both the operation display device 13 and the display device 15 display that the second person is present at the office.

Next, when the second person leaves the company, the “display 2” on the touch panel 20 may be touched with a strength of a certain value or more as in the case of leaving the office. This touch operation is detected by the display operation device 13, and it is detected that the "display 2" is surely pressed by the coordinate value and the pressure value, and the display frame of the "display 2" is turned off from the lighting state shown in the figure. At the same time, the second indicator light 16 of the display device 15 is turned off to display that the second person has left the company.

In the above embodiment, the touch panel using the SAW technology is taken as an example of the touch panel 20 having a pressure detection function, but the touch panel 20 is not limited to this, and in addition to the coordinate position. An appropriate touch panel can be used as long as it has a structure capable of detecting pressure. Further, although the above-mentioned embodiment is an example of the display operation device using the touch panel in the fire alarm system and the exit / return display system, the present invention is not limited to this, and a display operation device using the touch panel is also possible. It only needs to be provided and is not limited by the intended use.

[0029]

[Effect of the device]

 As described above, according to the present invention, the switch operation is performed only with a light touch of insects, clothes, etc., because the processing associated with the switch operation is not performed unless the touch panel is pressed with a force greater than a certain value. It is possible to surely prevent erroneous operation. Also, when the panel surface of the touch panel is cleaned, the switch is set so that it will not operate with pressure enough to wipe it with a cloth, so that the switch operation may be mistaken even if it is cleaned. Can be prevented.

Further, since it is not necessary to provide a mechanical switch and only the switch operation using the display on the display screen is required, the operation can be easily understood and the switch can be easily used. Of course, since there is no need to provide a mechanical switch, there is no restriction on the design configuration and the configuration can be simple. Furthermore, since all switch operations can be performed with the touch panel, there is no mechanical mechanism part, the durability against repeated operation is dramatically improved, and there is no corrosion of the contact part, resulting in high reliability.
