Abstract

PURPOSE:To improve the transfer efficiency of a processed telegraphic message, by managing the status of a processing task on a processor side, in a repeating device. CONSTITUTION:In a repeating device 4 which receives a telegraphic message D1 from a terminal equipment P1, a control part 6 stores the telegraphic message D1 in a buffer area G1 and also discriminates the kinds of processing tasks (TA-TZ) for the telegraphic message D1 to write the address of the buffer area G1 in a registration field (f) for a page A of a table 8 in, for example, a processing task TA. Then, the telegraphic message D1 is sent out to a processor 1. After deciphering the telegraphic message D1, a processing part 2 starts the processing task TA to perform processing. When the processing ends normally, the processing part 2 reports the normal completion of the processing task TA by information CA on the normal completion. If a fault occurs in the middle of the processing, information HA on the abnormal completion is generated. In case of the occurrence of the fault, the telegraphic message D1 in the buffer area G1 is held as it is on a repeater side 4 to handle a request to resend generated later.

Description

[Detailed Description of the Invention] (1) Technical field of the invention - Data transfer 1i11#ManniK [Su,! 1゜(b) Conventional A method and hAj single point terminal connect to center KM via 5k6t in the network.
In the Hare-Kyu online system, the message from Shiosue is transferred to Ryun I through the buffer yt of the Chuho station.In such a system, the number of values from Ichiki Yu (P1 to Pn) 5tl shi in the telegram, and a torture tag permit (Tm~T1) according to the rotational trend is prepared.・Kenmai's theme transfer ll111-In Manshiki, the center also has a There was a huge gathering in Tasta, and the castle was destroyed in the brutal Tasta. , and from the terminal to An, 1t

・ (C) The purpose of the invention is to correct a frequent defect; therefore,
The purpose is to provide a data transfer control system that improves the transmission performance of telegrams. In a system in which the data from Ayubare and Tanaki is processed through the middle i11* location and later processed by the tin salt #C wife, the memory for storing the data from the A table in which the motions t*m of the processing tasks executed in the processing task are stored, a + mark in the data area in the -ml memory, and a + mark in the data area in the -ml memory, and a table in the kIIU - -Hasaki received the authority from the cocoon 1 area noodle and set the 11 torture mesku 1 animal or Act boss shape clearing- to the 11 table, and received data from the IiJ Kishiki Iron Equipment. According to the dissection table in the form of the processing task in which the data is processed, only in the case of one sense, the data is sent to the KNW local completion, and it is stored in the memory of the first generation in 8th time, and the #J1 processing is executed. Data transfer that aims to erase the data stored in the σ memory at the time of receiving a notice of approval from the local staff from the local area 1: (e) Takamei's example: The present invention will be explained with reference to Fig. 1, which shows a block 1 that carries an unexploded example, 69, an IT processing device, 2 a processing unit, 3 an Oki ring, 4 a Relay device, 51

AG Tz is a 6-ru salt mesk.A table 8 is installed in the middle sister narrow 4th corner of the IjO where the tin salt thorn 111" ICC can be performed. 0 When this table 8 task/l*@ne/nia escape task is in the process of stopping enrichment, #IC is 1d: No. ``1'', and when there is an abnormality, the signal ``0'' is set. In the group Lee I, it is a mesuku T.

This state of information is set by the control unit 6 when receiving a report from the insect device. With such a wiping motion, for example, a message D@

contains the data d to be processed, and the type of the round ring task (Tm~1゛z) is assumed to be incorrect depending on the message format (its control information 11i). ・The relay tc that damaged the message DI At step 4, the control s6 stores the message Ds in the buffer area G, and also distinguishes between processing tasks (T~Tz) that can be processed by the message Ds. For example, in the case of the local task T, Registration column fK buffer 1 of section A of table 8
Fold in the address of the chin area G easy, then the table 80

If i successfully completes the KM, the processing station 2 sends a termination notification C to inform that the local task T has completed the termination of mistreatment.
14, the 111 control keyaki 6 refers to the data table 8, thereby erasing the message D1 in the buffer 1 area G1 of the buffer 1 memory 6. Also, in the case where an error occurs during the processing of the missed lI task T. Ktf, ^ Wealth End Ochi Hm is faded, so middle ms outfit 411ea pie 7: J' II m

Since it had to be retransmitted from Ps9, there was a drawback in terms of the retransmission procedure and transfer time. Also, the message D@ from terminal Pa was sent to Kandan Task 1 by 1J

When the relay device 4 receives a recovery notification (not shown) of the processing task T1, the tIIll@'NS6 writes a note rlJ to the task information awe in item 8 of the table 8, and then
The message D- in the buffer 111 area Ga is transferred to the processing # 111. In the example, the registered m of table 8 is NI [excluded in each item, but the a-row trend (Ps to Pn)

It's a joke.

(f) @ Ming's effect As mentioned above, Fuku Ming can put the tin salt equipment in the middle mi7 and use the salt pipe in the state of the salt task, so the transfer effect of local telegrams can be It has the advantage of being able to improve oneself.
