Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing device that can finely control input/output devices of a terminal.

In an information processing apparatus that includes a terminal control device and an input/output device, it is common practice to obtain a connection table between an input/output device adapter and an input/output device in order to control the input/output device. As shown in FIG. 1, a channel unit TMC, an input/output device adapter 10A, a coupling table (memory table for data storage) TBL, and a central processing unit
A terminal control device is configured with the CPU. Here, a terminal multiplexer channel TMC connected to the central processing unit CPU has multiple input/output device adapters IOA and an equal number of input/output devices IO
is connected. The operation of the terminal control device is controlled by an input/output device control means, ie, a basic program BS-PR, activated by the central processing unit CPU. Therefore, when power is turned on to the terminal control device, a sense command is sent to inform the input/output device adapter IOA of the model code of the input/output device IO, and the input/output device adapter IOA assigns its own number and executes the basic program. This join table TBL is obtained by notifying the BS-PR.
That is, when the power is turned on to the terminal control device, a power-on signal is notified to the channel TMC, and the number of the first input/output device adapter IOA connected to it is automatically replied.
Program BS-PR that controls channel TMC and controls input/output devices via channel TMC
knows the number of the input/output device adapter IOA. Next, in order to know the model code of the input/output device IO, the program BS-PR sends an "IO sense command" to the input/output device IO via the input/output device adapter IOA. At this time, the input/output device connected to the input/output device adapter IOA sends a return signal including the model code via the adapter IOA.
The program BS-PR analyzes this return signal and creates a combination table TBL that associates the input/output device adapter number with the input/output device model code.
(no data has been entered until that time). Since the number of the next input/output device adapter IOA is also known, the sending of the IO sense command and the returning of the IO function model code are repeated in the same manner as described above, and the connection table for one channel TMC is completed. On the other hand, actual input/output devices (IO) include various units such as printers, plasma displays, keyboards, etc., and it is rare to always have all the units that can be considered input/output devices. The types of display devices differ and the number of optional devices connected differs. Such a combined table that stores only the model codes of existing proposals
When obtaining a TBL and controlling input/output devices using it, the characteristics of the input/output devices can be managed, but specific units cannot be specified, resulting in rough control.

An object of the present invention is to provide an information processing device that allows input/output devices to be controlled more appropriately.

Embodiments of the present invention shown in the drawings will be described below. In the configuration diagram of FIG. 2, the same reference numerals as in FIG. 1 indicate the same components. The terminal control device in the embodiment shown in FIG. 2 includes a central processing unit CPU, a memory

Note that SVP is a management program that manages multiple application programs AP-PR1 and AP-PR.
2..., and also controls access to the basic program BS-PR via the gate. In addition, TBL is a memory table obtained in the present invention, un1, un2... are input/output device IO
The units that make up the system generally include a keyboard, etc. In the figure, when the terminal control device is in operation after power is turned on, the input/output device
When the IO is powered on, the input/output device IO sends a signal indicating that it has been powered on to the channel TMC via the adapter IOA, specifically the program BS−
Notify PR. At this time, the adapter IOA number is automatically added and notified, so the channel TMC control program BS-PR
learns the number of the input/output device adapter IOA and assigns the adapter IOA number to the memory table TBL.
Next, in order to know the model code of the input/output device IO, the program BS-PR sends an "IO sense command" to the input/output device via the adapter IOA. This causes the adapter to send this information to the input/output device IO. The input/output device connected to the relevant input/output device adapter IOA has a code other than its own model code,
Unit information such as units UN1, UN2, etc. that make up the input/output device IO is included in the adapter.
Send a return signal to IOA. In this case also the program
BS-PR analyzes the notified signal. In other words, at this time, as mentioned above, the adapter IOA adds the adapter number and notifies the program BS-PR, so the program BS-PR writes about the memory table TBL that associates the input/output device adapter number and the input/output device model code. I do. As a result, the model code and unit information are stored in the memory table TBL in correspondence with the number IOANo. of each adapter IOA of the channel TMC. In other words, from this memory table, it is possible to know what type of input/output device (eg, type of teller device, deposit/withdrawal device, type of bookkeeping machine, etc.) is connected to each adapter of the channel TMC. Further, from the unit information, it is possible to determine what IO unit (for example, type of keyboard, type of display, type of printer, etc.) is connected to each input/output device.

Next, since the application program AP-PR is notified that the memory table TBL has been created, the program AP-PR started by the management program SVP uses the input/output device IO that matches its own operating function. which adapter IOA
What is connected to the basic program BS
- Through the basic program BS-PR, it is possible to know this memory table TBL, specify the unit, perform access operation to a predetermined input/output device through the basic program BS-PR, and instruct execution of processing. .

The memory table TBL remains until it is cleared, and until then the association between the input/output device and the input/output device adapter remains. For example, clear channel
This is done by resetting the TMC during its initial operation.

In this way, the memory table is created for the input/output devices connected to the input/output device adapter at the time of powering on the terminal control device and during design and manufacturing, and also when the power is turned on on the input/output device side, the memory table is created for the It is now possible to create a table of input/output device adapter IOA versus input/output device IO and units. Therefore, input/output device adapter
If a failure occurs in one of the IOAs, if there is a free input/output device adapter IOA in the same channel TMC, reconnect the input/output device that was connected to the failed adapter. Output device
When the IO power is turned on, a new memory table TBL is created in the same way as described above, and each program AP-PR learns the input/output terminal from the model code with a predetermined function, and uses it. The adapter can be specified and processing is possible, and the input/output device IO is controlled via the channel TMC so that normal operation is possible. In this way, even when the memory table TBL is reconnected, there is no need to manually operate it from the outside; it can be rewritten by starting the input/output devices in a predetermined order, and the system can be rewritten by stopping the system and reconnecting. etc. is not necessary. Therefore, it is suitable for use as an intermediate control device called a cluster control section in each branch of a bank.

Furthermore, according to the present invention, it is possible to know the program for controlling the input/output devices individually regarding the equipment status of the units that make up the input/output device IO, so instead of controlling the input/output devices all at once, it is possible to control each unit in detail as necessary. control, and the information processing device can be highly efficient.
