Abstract

PURPOSE:To decide a representative terminal without informing a host by providing a pin setting means to respective terminal I/Os which are controlled by the host and starting a system only from a representative terminal whose pin is turned on. CONSTITUTION:Plural terminal I/Os 101-103 are provided with pin setting parts 111-113 respectively and one of them is on. The I/O whose pin is turned on diagnoses itself by an IPL when the host 1 is powered on and sends a start signal, e.g. date data to the host 1. The host 1 checks the sent date data to judge that all the I/Os of the system are ready to operate, thereby opening a terminal control program.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a plurality of input/output terminals (Ilo) under the control of a higher-level device (host), and uses one of them as a representative terminal to control the terminal of the higher-level device. This invention relates to a method for determining a representative terminal and starting the system without directly affecting the host in an information processing system that starts a control program.

[Conventional technology]

Conventionally, a seal search system as shown in Fig. 2 has been used, in which a host device (host) 1 is equipped with a main control unit (OPU) 2 and 7 aisles 3, and under the control of at least an input display such as a keyboard and a display. Input/output terminal (l10) with functions such as seal stamps and image leagues for signature verification, etc. 4
r e 4z e 4g . . . are connected to the data bus 5 in a similar manner. The startup method when turning on the power of this system is to select one of the multiple input/output terminals as the representative terminal, give a preload download instruction from the main control unit 2 of the host 1, and make the instructed terminal the representative terminal. A commonly used method is to send a signal designated as a terminal to the host and start a terminal control program. For example, among the VO groups connected to the bus 5, the L104t serves as a representative terminal and sends an activation signal to the host, indicating that all VOs belonging to that system are operational. This is not a representative terminal, but each V
This is because if O issued the activation signal without permission, it would cause confusion.

[Problem that the invention seeks to solve]

In the above system startup method, the main control unit 2 of the host 1
It is necessary to prepare a preload download instruction program and screen data for instructing the representative terminal I10. When the secondary representative terminal I10 goes down for some reason, it is necessary to correct and set the other representative terminals, but this correction procedure is complicated and time consuming.

In any case, complicated procedures must be determined between the main control unit of the host and the VO, and changes must be made in the event of a failure, requiring procedures that are highly interdependent.

An object of the present invention is to provide a method of determining a representative terminal and starting the system without directly affecting the host in a method of starting the system at a representative terminal I10 among a plurality of Vo under host control.

[Means for solving the problem] In order to achieve the above object, the system startup method of the present invention connects a host device and a plurality of input/output terminals, and starts the terminal control program of the host device from the input/output terminal. In the information processing system, the input/output terminal is provided with a setting means for instructing whether or not to send an activation signal to a higher-level device, and the setting means is set to on with any one of the input terminals being a representative terminal. , a system startup method in which the input/output terminal specified by this setting means sends out a startup signal when the power is turned on.

[For production]

With the above configuration, one terminal among the multiple terminals VO is designated as the representative terminal, the pin in the pin setting section is set to ON as the setting means, and all other terminals are set to OFF, so that from the representative terminal A start signal is sent to the host to open (start) the host's terminal control program.

In this case, since it is not caused by the host's preload download instruction, independent settings can be made without being directly affected, and even if the representative terminal goes down, you can simply change the representative terminal to which the pin setting is turned on. .

〔Example〕

, FIG. 1 (→ to (,+) are diagrams illustrating the configuration of an embodiment of the present invention.

The figure (α) corresponds to the conventional seal search system shown in FIG. The difference is that a plurality of terminals I/'010t+ 10gw 10g connected to the bus 5 are provided with bin setting units 11+ and 112.11J, respectively, and the system startup procedure using these units is different. That is,
The bin setting units 111 to 113 are configured by turning on the pins.
It has a function of sending, for example, date data to the host 1 as a startup signal after performing an IPL (initial setting load) and self-diagnosis when the host 1 is powered on.

The pin of this bin setting section is turned on only on the representative terminal I10,
Leave the other Ilo off.

In this way, the host 1 looks at the date data sent from the representative terminal I10, determines that all VOs in that system are operational, and opens the terminal control program. This makes it possible to operate all terminals VO.

In the same figure (6), terminal r, 'o 10 (101 to 103)
This figure shows an example of the configuration. The bus 5 is connected to the control section 7 via the line control circuit 6. In addition to the keyboard 0RT8, a seal image reader 9 is connected to the control section 7, and a bin setting section 11, which is the essential part of the present invention, is further provided. When an inquiry signal arrives due to the IPL of the host 1, each terminal performs a self-diagnosis, and since the pin of the bin setting section 11 of only the representative terminal is on, the control section 7 sends the date as the activation signal to which it should respond. Send data to host 1 via bus 5. Host 1 sees this and opens the terminal control program. Since the pin of the bin setting unit 11 of the other terminals is off, they do not respond to the make-up signal from the host. After opening the terminal control program, any terminal can be operated.

In this way, normal operation is performed and the specified Ilo
Enter the υ account number using the keyboard 0RT8, input the corresponding seal imprint from the image reader 9, register it in the host's file 3, and conversely send the imprint data read from the file 6 to the requested terminal. ) Verify and search for seals on invoices, etc.

FIG. 3C is a flowchart showing the operation of the embodiment of the present invention. That is, a timing signal is input to each terminal I10 via the bus 5 by the IPL when the host 1 is powered on, a check is performed by the self-diagnosis program, and if the setting pin is on, the system is opened as described above. Start up.

Also, if the setting bin is off, the system will wait for operation until the system opens.

〔Effect of the invention〕

As explained above, according to the present invention, a plurality of terminals VO are provided under the control of the host, each is provided with a pin setting means, and the system is configured to be activated only from the representative terminal that turns on this pin. It is. As a result, the representative terminal can be determined simply by setting the pin of the terminal VO without notifying the host, without having to directly relate to the host.

Furthermore, even if this representative terminal goes down, settings can be easily corrected for other terminals I10 regardless of the host.
