The computer main body control unit 32 includes a computer main body start / end control unit 34. The computer main body 12 does not include an input device such as a keyboard and a mouse and an output device such as a CRT display, a liquid crystal display, an organic EL display, and a plasma display.

  Looking specifically at each part of the touch panel display 11, the display unit 20 performs display based on a control signal from the touch panel display control unit 24. For example, display is performed based on an image stored in the touch panel display storage unit 23. The display unit 20 preferably employs a thin type such as a liquid crystal, an organic EL, or a plasma method.

  The touch panel 21 is for user input, is provided on the display unit 20, and specifies the coordinates of the user's pressing position with respect to the image of the input key displayed on the display unit 20. The coordinates are specified by processing an output signal from the touch panel 21 by the touch panel display control unit 24. Then, based on the result of specifying the coordinates, the pressed key is specified among the input keys displayed on the display unit 20, and the input instruction is determined. As the touch panel 21, various methods such as a transparent resistance film method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, and a capacitance method can be employed.

  The power switch 22 is a switch for activating the touch panel display 11 when pressed by the user. For example, the power switch 22 is provided in an easy-to-operate place such as a front frame of the touch panel display 11. The touch panel display storage unit 23 stores OSD (On Screen Display) data such as a program necessary for the touch panel display 11 and a setting screen, and an HDD or various memories can be used.

  The touch panel display control unit 24 controls each unit of the touch panel display 11, and the determination unit 27 determines whether or not the setting is made to control the computer main body 12 when the power switch 22 is turned on / off. Judgment. The touch panel display activation / termination control unit 28 outputs an on / off instruction to the touch panel display power supply circuit 25 in response to an on / off operation of the power switch 22. The computer main body start / end signal generator 29 generates a start signal, an end signal, a restart signal, and a forced end signal for the computer main body 12, and generates various signals in accordance with the operation of the touch panel 21 and the power switch 22. Is done.

  The touch panel display power supply circuit 25 is a circuit for turning on / off the touch panel display 11 and is driven based on a control signal from the touch panel display activation / termination control unit 28. The computer main body start / end signal transmission unit 26 transmits a start signal, an end signal, a restart signal, and a forced end signal of the computer main body 12. The signal from the computer main body start / end signal generation unit 29 is transmitted to the computer main body. 12 to send.

  Next, looking specifically at each part of the computer main body 12, the computer main body start / end signal receiving unit 30 receives the start signal, the end signal, the restart signal and the forced end signal from the touch panel display 11, This is output to the computer main body start / end control unit 34.

  The computer main body storage unit 31 stores programs and data necessary for the computer main body 12, and an HDD or various memories can be used. The computer main body control unit 32 controls each part of the computer main body 12, and the computer main body start / end control unit 34 responds to the received start signal, end signal, restart signal, and forced end signal according to the computer main body power supply. An on / off instruction is output to the circuit 33.

  Next, operations of the touch panel display 11 and the computer main body 12 will be described. FIG. 3 is a flowchart showing the operation on the touch panel display main body 11 side regarding the activation control of the computer main body 12, and FIG. 4 is a flowchart showing the operation on the computer main body 12 side regarding the activation control of the computer main body 12.

  Here, it is assumed that the touch panel display 11 and the computer main body 12 are turned off. First, according to FIG. 3, when the touch panel display activation / termination control unit 28 determines in step S10 that the power switch 22 has been turned on, it proceeds to step S11 and outputs a signal for instructing the touch panel display power circuit 25 to turn on. The touch panel display 11 is activated.

  And it progresses to step S12 and the determination part 27 determines whether the setting state of the touch panel display 11 is a 1st mode. The first mode is a mode in which an activation signal of the computer main body 12 is transmitted to the computer main body 12 when the power switch 22 is turned on. That is, in this mode, both the touch panel display 11 and the computer main body 12 are activated by turning on the power switch 22. Switching between the first mode and the second mode to be described later may be performed by a user using a setting screen on which OSD is displayed, a dip switch provided on the touch panel display 11, or the like.

  If it is determined in step S12 that the determination unit 27 is in the first mode, the process proceeds to step S13, and the computer main body activation / termination signal generation unit 29 generates an activation signal for the computer main body 12, and the process proceeds to step S14. The main body start / end signal transmission unit 26 transmits the start signal of the computer main body 12 to the computer main body 12 and ends the processing.

  On the other hand, when the determination unit 27 determines in step S12 that the mode is not the first mode, the process proceeds to step S15, and the determination unit 27 determines whether or not the setting state of the touch panel display 11 is the second mode. The second mode is a mode in which when the touch panel 21 is operated for a predetermined time after the touch panel display 11 is started, a start signal for the computer main body 12 is transmitted to the computer main body 12. That is, this is a mode in which the computer main body 12 is activated when the user operates the touch panel 21.

  If it is determined in step S15 that the determination unit 27 is in the second mode, the process proceeds to step S16 to determine whether or not the touch panel 21 has been operated in a predetermined manner. The predetermined operation here is, for example, operating a computer main body power key on a setting screen displayed by OSD. The OSD screen can be displayed, for example, by operating the upper left corner, the upper right corner, and the lower right corner of the touch panel 21 in this order, or by simultaneously operating (two-point pressing) the upper left corner and the upper right corner. . A setting screen can be displayed as a function of the OSD screen.

  If it is determined in step S16 that the determination unit 27 has been operated in a predetermined manner, it is determined that the computer main body 12 has been instructed to turn on, the process proceeds to step S13, and the process continues to step S14. On the other hand, if it is determined in step S15 that the determination unit 27 is not in the second mode, neither the first mode nor the second mode is set, and the processing is ended as it is. In this case, in order to activate the computer main body 12, it is necessary to directly operate a power switch (not shown) of the computer main body 12 as in the prior art. If only one of the first and second modes can be selected, the computer main body 12 may not have a power switch.

  Next, according to FIG. 4, in step S <b> 20, the computer main body control unit 32 of the computer main body 12 determines whether an activation signal of the computer main body 12 is received from the touch panel display 11. When the activation signal is received, the process proceeds to step S21, where a signal for instructing the computer main body power supply circuit 33 to be turned on is output, and the computer main body 12 is activated.

  In addition, as another specification of the touch panel display 11, it may be fixed to either the first mode or the second mode. In this case, it is not necessary to determine which mode is step S12 or step S15 shown in FIG.

  Since the touch panel display 11 is used as an HMI, the touch panel display 11 is installed in a place where the user can easily operate. Thus, by enabling the computer main body 12 to be started from the touch panel display 11 as described above, Even when installed in a device monitoring control system such as a plant, the operator does not have to go to the computer main body installed in a limited space. Therefore, the operability of the computer is improved for the operator.

  In addition, according to the above configuration, compared to the case where the power switch of the computer main body is extended from the computer main body and provided near the touch panel display, no new wiring is required in the device monitoring control system, so the wiring is reduced. be able to. Therefore, it is possible to prevent the maintenance and inspection of the device monitoring control system from becoming complicated for the administrator.

  In addition, when the second mode is set, the computer main body 12 does not start unless the touch panel 21 is operated in a predetermined manner. it can.

  In the above flowchart, the activation has been described as an example, but the present invention can also be applied to termination, restart, and forced termination. For example, a signal for ending or restarting the computer main body 12 may be transmitted from the touch panel display 11 to the computer main body 12 by performing a predetermined operation on the touch panel 21 (for example, operating an end key or a restart key from the menu screen). . Further, for example, by turning off the power switch 22 of the touch panel display 11, the touch panel display 11 may be turned off and a signal for forcibly terminating the computer main body 12 may be transmitted from the touch panel display 11 to the computer main body 12.

  In the present invention, the touch panel display may be activated by the operation of the power switch from the standby power state, or from the standby power state, not by the power switch operation, either will do. Similarly, the computer main body may be activated by the activation signal from the touch panel display from the standby power state, or the computer main body is energized only by operating the power switch of the touch panel display instead of the standby power state. Or either. This means that the computer main body is supplied with power via the touch panel display.

  In the present invention, a signal such as an activation signal may be sent using an unused pin for a cable for transmitting and receiving an image signal and a touch panel operation signal for connecting the touch panel display and the computer main body. .

  In the present invention, if a plurality of computer main bodies are connected to one touch panel display, each computer main body can be activated, terminated, restarted, or forcibly terminated with the one touch panel display.

  Touch panel display of the present invention, computer main body connected thereto, computer including these touch panel display and computer main body, touch panel display control method, computer main body control method, computer control method, and touch panel display The control program of the computer and the control program of the computer main body are useful when the touch panel display and the computer main body are installed apart from each other, and are particularly useful for industrial computers installed in production lines and plants. .
