Thus, the PLC includes a wired / wireless communication repeater, and when the user's touch display device is wireless, the PLC's wired / wireless communication repeater is switched to wireless communication to wirelessly communicate with the touch display device, and the touch display device is wired. In the case of the PLC's wired and wireless communication repeater to convert the wired communication to the wired display device and the communication with the touch display device, but also the touch display device to operate either wired or wireless, so in the actual site There were still difficulties in selecting the right touch display device for the situation.

It is an object of the present invention to provide a wired / wireless combined touch display device which can be used while the user freely selects and moves with wire or wireless communication with the PLC of the device according to the field situation.

Another object of the present invention is to maximize the flexibility in communication with the PLC by making it convenient to use wired or wireless communication with the PLC in the touch display device to move conveniently.

In order to achieve the above object, the present invention provides a touch screen for recognizing a touch, a display unit for driving a display when the touch screen is touched, a display control unit for controlling driving of the display unit, and receiving a control signal from the display control unit. A power control unit for controlling the power supplied to the unit, a central processing unit for receiving a signal controlled by the display control unit and controlling the predetermined program and outputting the controlled signal; A communication unit for transmitting or transmitting a signal transmitted from the PLC to a central processing unit, and the communication unit includes a wired / wireless conversion detecting unit for detecting a wired or wireless connection conversion and outputting a control signal according to the detected conversion to the central processing unit. It will be included.

The communication unit may interface with both wireless communication and wired communication, and selects any one of the communication to communicate.

The wired / wireless conversion detector includes a voltage detector configured to detect a power supply voltage connected to a communication unit, and a controller configured to output a communication signal corresponding to the voltage detected by the voltage detector to a central processing unit.

Therefore, according to the present invention, the wired / wireless conversion for detecting a power supply voltage and outputting a control signal according to the detected voltage in a communication unit of a touch display device that connects to the PLC of the factory automation device in an industrial field and instructs and displays an operation command by touch. In accordance with the wired or wireless communication of the PLC, the touch display device is converted into a wired or wireless communication corresponding to the communication with the PLC, so that the touch display device is wired or It can be freely selected wirelessly and conveniently used while moving, thereby maximizing flexibility in use and communication of touch display devices.

Figure 2 is a control operation of the mobile touch display device of the present invention wired and wireless communication

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the touch display device 20 that performs wired or wireless communication with the PLC 10 of the present invention includes a touch screen 21, a display unit 22, a display control unit 23, and a power control unit 24. ), A central processing unit 25, a communication unit 26, wired and wireless conversion detection unit 27.

The touch display device 20 is wired or wirelessly connected to the PLC 10 to transmit a control signal to the PLC 10 and to display data transmitted from the PLC 10.

The touch screen 21 allows a predetermined amount of current to flow through the pad coated with the transparent conductive metal material, and then displays a portion of the current change portion when the user touches the pad.

The display unit 22 displays an input command symbol, a character, and the like on the screen for the touch of the touch screen 21.

The display control unit 23 controls the driving of the display unit 22 when the touch screen 21 is touched.

The power control unit 24 receives a control signal from the display control unit 23 to control the power supplied to the display unit 22, and when there is no control signal, the power of the display unit 22 is turned off. .

The CPU 25 receives a signal controlled by the display control unit 23 and controls it by a preset program, and outputs the controlled signal.

The communication unit 26 transmits a signal controlled by the central processing unit 25 to the PLC 10, or transmits a signal transmitted from the PLC 10 to the central processing unit 25, where The communication unit 26 may interface with both wireless communication and wired communication, and communication is performed by selecting any one of the communication.

The wire / wireless conversion detection unit 27 detects a conversion according to a wired or wireless connection from the communication unit 11 of the PLC 10 to the communication unit 26 of the touch display device 20 and controls the detected conversion. In addition to transmitting the signal to the central processing unit 25, and transmits the control signal according to the detected conversion to the communication unit 26.

The wire / wireless conversion detector 27 outputs a communication signal corresponding to the voltage detected by the voltage detector 271 and the voltage detector 271 to detect the power supply voltage connected to the communication unit 26 to the central processing unit 25. The control unit 272 is configured.

The voltage detector 27 divides and detects a power supply voltage applied to a power supply line by a voltage dividing resistor when the wire is connected to the communication unit 26.
