能となる。The terminal control device program detects that all display devices have been powered off and turns off its own device, so when multiple display devices are in use, if one display device is powered off, The power to the terminal control unit is cut off, and other operators in use are not affected. It is also possible to prohibit automatic power-off by commands from the center, so even if the display device is powered off, the terminal control device can be prohibited from turning off the power, and the operation of only the terminal control device is also possible. It becomes possible.

替る。FIG. 2 is a block diagram of the terminal control device, in which the CPU 6 executes programs in the program memory 8 one instruction at a time, and uses the random access memory 7 to store various control information, thereby realizing the function as an online terminal. In the display devices 3-1 and 3-2, the display device control circuit 12 is controlled by a program executed by the CPU 6, and the data transmitted from the center is displayed on the screen. In addition, the data input by the operator to the display device is passed through the display device control circuit and sent to the CP.
Control of the program executed by U is sent to the central location. The switching circuit 9 and the remote power supply control circuit 10 are powered by a battery. In the power-off state, the remote power control circuit detects a power-on command sent from the center, turns on the power to the terminal control device, sends a switching signal to the switching circuit, and switches the connection with the center to the communication control circuit 11. .

されていれば端末制御装置の電源を切断する。When the display device control circuit 12 detects a power-off of the display device, it sends a power-off detection signal to the CPU, and the CPU starts executing a power-off processing program. Commands from the center are reported to the CPtJ via the communication control circuit of the switching circuit 2, and are analyzed and processed by the program. An example of a command analysis and processing program is shown in FIG. If it is a power-off command, the power is turned off. If it is a power-off detection permission command, the power-off permission flag in the random access memory is set to on. If the command prohibits power-off detection, the power-off permission flag is set to off. An example of a power-off processing program executed when a power-off of a display device is detected is shown in FIG. 4, and sets the device area of the display device state management table in the random access memory to a power-off state. If the power-off permission flag is on and all display devices are set to a power-off state, the terminal control device is powered off.

が電源断してしまうことはない。According to the present invention, when all display devices are no longer used for business and are powered on, the terminal control device can also be automatically disconnected. It is also possible to prevent the power to the terminal control device from being automatically turned off from the center, so tasks that do not use a display device, such as updating disk files in the terminal control device, can be performed while only the terminal control device is powered on. It is. Note that if the power-off permission flag is initially set to OFF when the terminal control device is powered on, the terminal control device will not be powered off even if the display device is powered off.
