Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal connected to a host computer via a line, and more particularly to a method for remotely disconnecting terminal power from the host computer.

[Conventional technology]

Conventionally, this type of remote power-off of a terminal from a host computer involves the terminal operator manually turning off the power of the terminal by telephone contact from the host computer operator. Alternatively, the host computer controls the carrier signal flowing through the line connecting the host computer and a plurality of terminals from on to off, thereby controlling the terminal power-off on a line-by-line basis.

[Problem that the invention seeks to solve]

The above-mentioned conventional method of disconnecting the terminal power remotely from the host computer has the disadvantage that unattended operation of the bank CD ATM terminal is not possible because the terminal operator is involved when the host computer operator instructs the terminal operator to disconnect the terminal power over the phone. There is. In addition, if the host computer turns off the carrier signal flowing through the line connecting the host computer and multiple terminals to turn off the terminal, all terminals connected via one line will be powered off at the same time. Although it can be controlled, when multiple terminals with different operating hours are connected to one line, there is a drawback that power-off control cannot be performed for each terminal.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote terminal power-off method that allows power-off control for each terminal based on a message instruction from a host computer.

[Means for solving problems]

The configuration of the terminal power remote power disconnection system of the present invention is such that the host computer side includes an instruction means for instructing the host computer to turn off the power of each terminal unit, and the instruction means for converting the instruction from the instruction means into a data communication control format. A data processing means of a host computer, a message transmitting means for creating a terminal power-off instruction message using the processing means, and transmitting the terminal power-off instruction message to the terminal unit;'! - comprising, on each terminal unit side, message receiving means for receiving the terminal power-off instruction message; data processing means of the terminal unit for converting the terminal power-off instruction message into a disconnection command and giving a power-off instruction; The apparatus is characterized by comprising a power cutoff means for cutting off power to the terminal unit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention. In this embodiment, a data processing section 101 in a host computer 10, a message transmission processing section 1 as a message transmission means,
02, a host computer console 11, and a host computer 10. Terminal 13. A branch line 12 that connects the terminal 14 in a multi-drop manner, and the terminal 13 . Message reception processing unit 131, 1 which is a message reception means in the terminal 14
41, data processing units 132, 142. It is constituted by automatic power supply control units 133 and 143 including power supply cutoff means.

The host computer 10 analyzes and processes commands as instruction means input from the host console 11,
It has a function to perform processing based on the analysis result, and a message sending function to send an arbitrary message to the corresponding terminal. The host console 11 has a function for a host computer operator to instruct this online system by commands.

The branch line 12 has a function of transmitting a message sent from the host copier 10 to the terminal 13 or the terminal 14.

Terminal 13. The terminal 14 has a function of receiving a message from the host computer, a function of analyzing the received message and processing based on the analysis result, and a function of cutting off the power of each unit of the terminal itself based on instructions from this data processing section. has.

The operation of this embodiment in the online system shown in FIG. 1 will be explained. Terminal 13. Terminals 14 are both powered on, and the host operator executes the power off of only terminal 13, while the power of terminal 4 remains on. First, the host operator inputs the following command from the host console 11 that means ``Turn off power to all units of the terminal 13''.

T=1 ΔPOWERΔOFF △UNiT=AL
LHere, in the case of powering off only the line printer 17 of the terminal 13, specify rUNiT=171. This command is analyzed by the data processing section in the host computer 10, and after the analysis, the message transmission processing section is instructed to send a power-off instruction message to the terminal 13. Upon receiving this instruction, the message transmission processing section transmits a power-off instruction message to the terminal 13. Branch line 12 transmits this message from host computer 10 to terminal 13.

FIG. 2 shows a power-off instruction message for cutting off all units in this embodiment. In the figure, STX is 5 tarts of
Abbreviation for Text, the symbol at the beginning of the message, SA is 5tati
On Address is the abbreviation for the terminal, and UA is Uni.
tAddress is an abbreviation for a destination indicating a unit within a terminal. The English text that follows is a message, meaning "Turn off the power to all units", and ETX is End.
Abbreviation for "of Text" indicates the end of the message.

FIG. 3 shows a flowchart of the processing of the terminal 13 when receiving the power cut instruction message.

The power-off instruction message that has arrived at the terminal 13 is received by the message reception processing unit 131 within the terminal 13 . The content of this received message is analyzed by the data processing unit 132, and "execution of power-off of all units" is recognized. The data processing unit 132 in the terminal 13 that recognized this “execution of power-off of all units”
issues an “all unit power-off execution command” to the automatic power supply control unit 133. The automatic power control unit 133, which has received this "all unit power cut execution command j, cuts off the power to all units."

〔Effect of the invention〕

As explained above, the present invention provides a system for connecting a host computer and
In an online system in which a plurality of terminals are connected to a line, by remotely controlling the terminal power-off from the host computer in accordance with a telegram instruction from the host computer, it is possible to control the power-off of each terminal individually.
