Abstract

PURPOSE:To execute transmission reception and processing to a text by other input output device without keeping them awaiting so long by sending a long text while dividing the text when the long text takes place in a data processing unit of an on-line system. CONSTITUTION:When a test sent from a data processing unit 1 to an input output device 3-ij is longer than a predetermined length, the data processing unit 1 divides the text into plural shorter texts than the said length and sends the divided texts. Moreover, an index representing the tail end is added to the last text of the texts sent dividedly. A terminal controller 2-i receives sequentially the said plural texts and sends them sequentially to the input output device 3-ij. Then the input output device 3-ij receives and outputs the said plural texts sequentially and detects the index representing the tail end. When the index representing the tail end is detected, the input inhibit state of the input output device 3-ij is released and the state of inputting a succeeding data is transited.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a message transmission/reception processing system, and in particular to an online system in which a data processing device and N (N is a positive integer) input/output devices are connected via a line. This paper relates to a message transmission/reception processing method.

[Conventional technology]

Conventional message transmission/reception processing methods for online systems in which a data processing device and N input/output devices are connected directly or indirectly via a line perform the same transmission and reception processing for long messages as for normal length messages. Is going.

[Problem to be solved by the invention]

In the conventional message transmission/reception processing method described above, when a long message is generated in the data processing device of an online system, while the long message is being sent and received, the sending data processing device and the receiving input/output device , because the line in use is occupied for a long time, it takes a long time for the data processing device to receive messages from other input/output devices, or for the data processing device to send messages to other input/output devices. It has the disadvantage that you may have to wait for several days.

An object of the present invention is to divide and send the long message even when a long message is generated in a data processing device of an online system, thereby reducing the time required for sending, receiving, and processing the message in other input/output devices. It is an object of the present invention to provide a message transmission/reception processing method that can be carried out without having to cross the border and wait.

[Means to solve the problem]

The message transmission/reception processing method of the first invention provides a message transmission system for an online system comprising a data processing device and N (N is a positive integer) input/output devices connected directly or indirectly to the data processing device via a line. In the transmission/reception processing method, (A) If the message transmitted from the data processing device to the input/output device is longer than a predetermined length, the data processing device - converts the message into multiple messages shorter than the predetermined length. (B) The input/output device sequentially receives and outputs a plurality of messages sent in pieces from the data processing device.

Further, the message transmission/reception processing method of the second invention includes (A) a data processing device that, when a message to be transmitted is longer than a predetermined length, divides the message into a plurality of messages shorter than the predetermined length and transmits the message; (B) N (N is a positive integer) that connects directly or indirectly to the data processing device via a line and sequentially receives and outputs a plurality of messages divided and sent from the data processing device. It is configured with 1 input/output device.

Further, the message transmission/reception processing method of the third invention includes a data processing device and an M connected to the data processing device via a line.
An online system comprising (M is O or a positive integer) terminal control devices and N (N is a positive integer) input/output devices connected to the terminal control device or the data processing device by a line. In the message transmission/reception processing method, (A) If a message to be sent from the data processing device to the input/output device is longer than a predetermined length, the data processing device sends the message to a plurality of messages shorter than the predetermined length. (B) The terminal control device transmits the data from the data processing device,
Sequentially receives multiple messages that are sent in pieces,
(C) The input/output device sequentially receives and outputs a plurality of messages sent in pieces from the terminal control device. .

Next, embodiments of the present invention will be described with reference to the drawings.

It has N (N is a positive integer) input/output devices including n.

FIG. 2 is a flowchart showing an example of the operation of the input/output device of this embodiment.

First, the input/output device 3-ij converts the input data into a telegram in step S1 of FIG. 2, and transmits it to the terminal control device 2-i in step S2. Input to -ij is prohibited, and the message output of the processing result is awaited.

Therefore, the terminal control device 2-i transmits the transmitted message to the data processing device 1 via an intermediary, and the data processing device 1 receives the transmitted message and performs necessary processing.

If the message sent from the data processing device 1 to the input/output device 3-ij is longer than a predetermined length, the data processing device 1 divides the message into multiple messages shorter than the predetermined length. Sending.

It should be noted that, for the messages to be sent in parts, an indicator indicating "continuation" is added to an intermediate message that is not the last message, and a marker indicating "final" is added to the last message.

Further, the terminal control device 2-i receives from the data processing device 1,
Sequentially receives multiple messages that are sent in pieces,
It is sequentially transmitted to the input/output device 3-ij.

Therefore, in step S4, the input/output device 3-ij sequentially receives a plurality of messages that are divided and sent from the terminal control device 2-i, outputs them in step S5, and outputs them in step S6. , a mark indicating "final" is detected.

In step S6, when an indicator indicating ``continuation is present'' is detected, the process returns to step S4 to repeat the reception and output, and when an indicator indicating ``final'' is detected, in step S7, the input/output device 3-ij is The input prohibition barking state is canceled and the next data input is started.

[Effects of the Invention] As explained above, the message transmission/reception processing method of the present invention has the following effects:
Even when a long message is generated in the data processing device of an online system, by dividing the long message and sending it, you do not have to wait too long for the message to be sent, received, or processed by other input/output devices. It has the advantage that it can be implemented in many ways.
