DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a touch-operated input device for use in combination with a display.

(Prior Art) Various types of touch panels, such as optical type and contact type, have been used as touch-operated input devices. FIG. 4 shows a configuration example of a conventional touch-operated input device using a contact-type touch panel. These have a configuration in which one touch panel is provided for one display, and in the event of a touch panel failure or touch panel controller malfunction, 1. It was outrageous that incorrect information was entered.

In FIG. 4, 1 is a display, and a display controller 2 displays a screen for touch operation. Then, when you touch the contact type touch panel 5,
A touch operation command signal 8 is input from the contact type touch panel controller 6 to the control device 9 . As a result, the control device 9 operates to output a control output 10 based on the touch operation command signal and the information on the touch operation display screen.

(Problems to be Solved by the Invention) The conventional devices described above do not have any protection measures against accidentally touching the contact type touch panel.

Therefore, in order to eliminate this type of erroneous input, the use or exclusion of the touch system is set based on commands from other input devices, or in this case, the operation is complicated.

Furthermore, when using a touch system, incorrect input may occur due to flying insects, foreign objects, etc. when using an optical touch panel, and due to kissing or deformation of the touch panel when using a contact type touch panel. It became. Moreover, the touch panel controller 1 to roller failure prevention is only a self-diagnosis of the controller 1 to the roller, making it difficult to improve the reliability of the touch system.

The present invention has been made to solve the above problems, and by duplicating the touch panel, which is the basic component of the input device, and the accompanying controller part with different systems, it is possible to prevent erroneous input due to malfunctions, etc. The purpose of the present invention is to provide a touch-operated input device that can prevent this.

[Configuration of the Invention] (Means for Solving the Problem) FIG. 1 shows an example of the configuration of a touch-operated input device according to the present invention.

An optical touch panel 3 and an optical touch panel controller 4 are combined with a contact type touch panel 5 and a contact type touch panel controller 6 to a display 11 for screen display for touch operation, a display controller 2 for screen control, and input systems of different methods are provided. Duplicate. and,
The control device 9 is provided with a signal determining section 9D that compares two independent types of touch operation input signals 7 and 8 and determines a normal human input signal. This makes it possible for the signal determining unit 9D provided in the control device 9 to eliminate erroneous input signals input from one of the touch panels 3 and 5 and the touch panel controller 4.6.

(for production) The present invention will be described in detail with reference to FIG.

By display controller I roller 2, display gray 1
” Second, with the touch operation screen displayed, touch the display surface to perform touch input. At this time, the operator's operation is detected using the optical touch panel 3 and the contact type touch panel 5, and the information on the position where the touch was made is sent as a touch operation command to each of the evening and winter panels 1 to 1 to the rollers 4 and 6. It is input to the control device 9 as a signal 7.8. The control device 9 receives individual touch operation command signals 7,
After converting each into an operation signal based on the information on the display screen 8 and the touch operation display screen, the signal determination section 9D determines whether the two are stopped and the necessary signal is selected as the control output 10. This makes it possible to eliminate the occurrence of language errors on the touch panels 3 and 5 and the touch panel controller 4.6.

(Embodiment) FIG. 2 shows an example in which the touch-operated input device of the present invention is applied to a process control device.

FIG. 3 shows an example of internal processing of a control device used in a touch system.

A display controller I roller 2 outputs a screen for touch operation to the display 1 .

The display 1 incorporates two different types of touch panels, an optical touch panel 3 and a contact touch panel 5, each of which independently outputs a touch operation command signal 78 to the control device 9 via the touch panel controller 46.

The control device 9 converts the screen position information 9a stored in the screen information memory record and the touch position information of the touch operation command signal 7.8 into the operation signal 9b in the signal converters 9B and 9C.
, 9c. Two independent operation signals 9b,
9c is logically ANDed by a signal determining unit 91), and when the two match, it is delivered to the process control device 11 as a normal control output 10, and the control valve 12 is controlled according to this, for example.

Next, the operation of this embodiment will be explained.

During normal touch operation input, the optical touch panel 3 and the controller 4 and the contact touch panel 5 and the controller 1 to
The data is converted into coordinate data on the screen using the roller 6 and output to the control device 9 as touch operation command signals 7 and 8.

Inside the control device 9, data such as touch operation attributes of the display screen I- is stored in the screen information memory 9^ at screen position 1〃information 9a.
The signal converter 9B. By comparing the touch operation command signal 7.8 at 9C, the coordinate data of the touch operation is recognized as a specific operation signal 9h9C.

The signal determination unit 9D determines that the two types of operation signals 9b and 9c generated from the signals input from each of the optical and contact touch operation ends are the same signal as a normal touch input. By taking the logical product of the two in
It is possible to obtain the control output 10 that eliminates the abnormal input that occurs in one system.

In the example, if the control output 10 changes the setting value of the process control device 11, the process control device 11 changes the setting value according to the control output 10, which is output only when the touch system determines that it is normal. It will be done.

According to the above embodiment, by adopting the touch system, it is possible to eliminate erroneous inputs that occur in one system of the touch operation circuit, and it is possible to improve reliability, which has been difficult with conventional touch systems. I can do it.

In other words, it is possible to eliminate both erroneous inputs caused by flying insects and foreign objects, which were difficult to achieve with optical touch panels alone, and erroneous inputs caused by scratches and deformation of the touch panel, which were difficult to achieve with contact touch panels alone. . Also,
At the same time, it is basically possible to eliminate erroneous inputs caused by failures in the touch panel controller as well as failures in one system, and when a failure in one system is detected, the reliability of the control device can be improved by determining that input is normal only from the healthy system. Improve further. In particular, even in cases where high reliability is required, such as nuclear power generation control, the present invention can be applied.

The display device described above is applicable to all of CRT, [[, liquid crystal, plasma, etc.].

[Effects of the Invention] As explained above, according to the present invention, it is possible to eliminate erroneous inputs that are a problem when using an optical/contact type touch panel alone, and erroneous inputs caused by a failure of the touch panel controller. A highly reliable touch-operated input device can be provided.
