Abstract

PURPOSE:To decrease the load of a job processing processor, by performing the detection of interruption source generation of a terminal device and data READ/ WRITE processing with an AUTO-POLLING controlling processor. CONSTITUTION:The job processing processor 2 sets A-POL information on an A-POL controlling table 6 and gives an A-POL processing start command to the A-POL controlling processor 3. The processor 3 gives a command for the start of A-POL to an A-POL controlling circuit 4. The controlling circuit 4 transmits the A-POL to a terminal device 8. When a response controlling circuit 10 receives the A-POL, the reception is informed to a processor 9. The processor 9 instructs the transfer of data of an A-POL response storing memory 12 to the response controlling circuit 10 to perform the data transfer. When the POL type requires data READ or WRITE, the processor 3 outputs a READ/WRITE issusing command to the A-POL controlling circuit 4 and when the response is received from the terminal, whether or not the processing of the commanded POL type is finished is discriminated.

send

The business processing processor 2 receives the command from the command control device 3.
When the status information of the terminal is stored in the data storage memo 1 and 4 via the data line 14, the status information is checked and determined via the data line 15, and if an interrupt factor has occurred, the interrupt factor is analyzed and processed. Start. If no interrupt factor occurs, data lines 16, 17...
. . , the occurrence of interrupt factors in other terminal devices is detected in the same way.

The problem with the conventional technology is that the business processing processor 2
F
LEAl) command is issued and executed, it is not possible to detect the occurrence of an interrupt factor in the upper terminal device during business processing.

Also, issue the REAI) command to the terminal device - white line,
It is necessary to determine the occurrence of an interrupt cause, and even when no interrupt has occurred, the status information of the terminal device is
) and the business processing processor must make the determination. For this reason, the load on the business processing processor increases, resulting in poor business processing efficiency.

OBJECT OF THE INVENTION The object of the present invention is to solve the conventional problems as described above.
A-)'01・The control processor detects the occurrence of an interrupt factor in the terminal device ρ and processes the data R.
HA IJ/WRIT); By performing this processing, the load on the business processing processor can be reduced, and business processing and interrupt factor occurrence detection on the terminal device can be processed in parallel.

Conventionally, business processing and REAI were performed using a business processing processor.
) Since the occurrence of an interrupt factor on the terminal device is detected using commands, it is not possible to detect the occurrence of an interrupt factor during business processing, and even when no interrupt factor has occurred, the status information of the terminal device can be read and used for business processing. The processor must make the determination, which increases the load on the business processing processor and reduces the efficiency of business processing.

Therefore, A-P (J L ?B11 #The processor detects the occurrence of an interrupt factor in the terminal device according to the instruction from the business processing processor).
).

By performing WRITE processing, the load on the business processing processor is reduced, the efficiency of business processing can be improved, and the parallel processing of business processing by the business processor and the detection of the occurrence of an interrupt factor on the terminal device can be performed with e=J' function. It is something to do.

Embodiments of the Invention Next, implementation EFIJ of the present invention will be explained in detail with reference to the drawings. Configuration of Embodiment FIG. 2 shows a block diagram of a terminal control device which is an embodiment of the present invention.

Memory 5 consisting of A-POL system control table 6 data storage memory 7, business processing processor 2, A-1'OL?
! A terminal control device 1 incorporating an IJ control processor 3, an A-POL control circuit 4 (which issues commands once), a terminal control processor 9, and an A-POL response memory 12
and a status information storage memory 13.
It consists of a terminal device 8 that controls a response control circuit 10.

Operation of the embodiment The business processing processor 2 in the main control device It1 reads the A-LPOL control table 6 in the memory 5 (A-POL control table corresponding to the terminal device @i: A-POL type, A-POL type, A start/stop command: is set to A-POL+ via data line 14, and A-POL+ is set via data line 15.
An instruction to start A-POL processing is issued to the control processor 3. A
-PUL control control cello sensor 3-A- via the data wire 16;
Looking at the t'OL control table, in order to start A-POL to the terminal device that has the A-POL start instruction, the A-POL control circuit 4 is instructed to start A-P (JL) via the data line 17.A- POIJIJ control circuit 4 sends A-POL to terminal device [8 via data #!19.

When an interrupt factor occurs, the in-terminal processor 9 stores the interrupt factor occurrence in the A-POL response payment memory 12 and the interrupt factor in the status storage memory 13 via the data line 21. If no interrupt has occurred, information 7 A-1' that indicates no interrupt cause is stored in the OL response storage memory 12.

When the j, 6 answer control circuit 10 in the terminal device receives A-1'OL, it sends 8-POL to the processor 9 via the data line 20.
Notify me of e-mail. The processor 9 instructs the response control circuit 10 to transfer data from the A-POL response storage memory 12 in the terminal memory 11 via the data edge 20.
The data is transferred via the edge 19. Furthermore, when an interrupt factor occurs, data in the status information storage area 13 can be added.

The A-POL control circuit 4 in the terminal control device 1 is an A-POL
When a response to A is received, the response is stored in the status information storage memory 7 via the data line 18, and is sent to
- Notify the POL control processor 6 of the receipt of the response.

A-)'OL system both Grossenosa 3 is connected via data line 16,
Look at the A-POL response in the status information storage memory 7,
The interrupt factor occurrence status is determined, and if no interrupt factor has occurred, the A-POL control table 6 is checked, the terminal device for the next A-POL activation request is checked, and the A-POL activation request is sent to the terminal device for which the POL activation request is set. PUL is issued and raw detection is repeated from the terminal device's interrupt request).

If an interrupt factor occurs, A -P (J Ti fb

- A-PUL of the occupied terminal device in the POL control table 6
Clears the information (stops POL, etc.) and interrupts the business processing processor via the data line 15.

data REAL) or W l (+ T F2 is required, A-POI, control processor 3
issues a command to issue the A-POLtHIJ quotient 1 circuit]A1)/WRITE command via the data edge 17, and upon receiving a response from the terminal, determines whether the instructed i' o L(= processing is complete). If the processing is completed, the A-POL control table 6 is cleared and the data edge 15 is slightly interrupted to the business processor.

The business processing processor performs business processing.

The A-4'tJL scream control glosser 6 looks at the A-POI and the control table 6, and checks the next A-P (JL start @ compromise terminal device). Detection of occurrence of old 11 in the device is repeated one after another.

The business processing processor 2 handles interrupts from terminal devices.

When it is necessary to detect the occurrence of a factor, set 205 types that are effective for business in the corresponding terminal device A-POL notification area in the A-POL control table 6, and perform A-POL control to detect the occurrence of an interrupt. command to the processor 6.
