Abstract

PURPOSE:To prevent the breakage of data caused by a misoperation and to shorten work suspension time by organically coupling a data receiving function for receiving the data from a relay source system and a data transmitting function for transmitting the data to a relay destination system and adding a supervising function to the organically coupled functions. CONSTITUTION:A data receiving means 14 receives the data inputted in a relay source system 1 using a communication managing function, a data transmission requesting means 13 requests a relay destination system 3 to accept data transmission, and a data transmitting means 16 transmits the data to the relay destination system 3 using the communication managing function. Further, the data are read/written for a memory 19 by a memory part access means 15, the restoration of the relay destination system 3 when a failure occurs in the relay destination system 3 is supervised by a supervising means 17, and the status of receiving the data from the relay source system 1 and the status of transmitting the data to the relay destination system 3, for example, a relay source identifier, the number of the data, receiving/ending time, etc., are displayed on a display part 12 by a relay status display means 11. Thus, the work suspension time can be shortened, and the breakage of the data caused by the misoperation can be prevented.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data relay system, and particularly to a relay system that is located between a terminal and a host computer and has a relay function in data exchange between them. The present invention relates to an efficient data relay system that realizes data relay without involving people and automatically monitors host system failures and failure recovery.

[Conventional technology]

Conventionally, when this type of data relay system performs data relay, data reception from the relay source system and data transmission to the relay destination system are executed by separate terminal devices, and the data 70. This was accomplished by replacing the controller and alternately starting and stopping the program.

In addition, restarting the host system after recovery from a failure was generally performed manually.

[Problem to be solved by the invention]

In the conventional data relay described above, the data replacement operation of 70 pieces of data at a predetermined time and the start of the program are realized by human intervention, which reduces time efficiency and prevents operational errors. As a result, data may be corrupted and transmission timing to the host system may be lost.

Also, it is fine if it is used once or twice in 7 days, but
If the number of operations is 5 to 6 times per day, it is natural that the efficiency will further deteriorate.

[Rounding method to solve the problem]

The purpose of the present invention is to solve the above-mentioned drawbacks, and by organically combining two programs and sharing information, the time loss that may occur when relaying data and the troublesome intervention to obtain it can be reduced. The objective is to provide an efficient relay system that solves the problem.

The data relay system of the present invention includes means for receiving data input in the relay source system using a communication management function;
A means for making a transmission request to a relay destination system, a means for transmitting to a relay destination system using a communication management function,
means for reading/writing data to/from a storage device;
It has a recovery monitoring unit in the event of a relay destination system failure, and means for displaying data reception from the relay source system and data transmission status to the relay destination system (for example, relay source identifier, number of data items, and reception/end time). ing.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic diagram of an embodiment of the present invention.

In FIG. 1, one embodiment of the present invention shows a relay source system 1. Relay destination system 3. In a data relay system having a relay system 2 that controls the relay, data inputted by a data manual/instruction means 4 is stored in a data storage section 9 via a storage section access means 8. When there is a data transmission instruction request from the data manual/instruction section 4, the data transmission means 6 reads out the data held in the data storage section 9, and transmits the data to the communication management section 7.

The data transmitted by the data transmitting means 6 is received by the data receiving means 14 of the relay system 2, and is stored in the data storage section 19 via the storage section access means 15. At the same time, the relay source identifier, operating time, and number of data items present in the received data are constantly displayed on the relay status display section 12 by the relay status display means 11.

When the data reception operation of the data reception means 14 is completed, a data transmission request 13 requests the data transmission means 16 to transmit data to the relay destination system 3, and the data transmission 1
6 uses the storage section access means 15 to re-input the data from the relay source system 1 stored in the data receiving means 14, and transmits the data to the relay destination system 3.

In this case, similarly to the relay status display by the data receiving means 14, the relay status is displayed by the relay status display means 11, and the display unit 1
2. The data transmitted by the data transmission means 16 is sent to the communication management section 18 of the relay system 2, the communication management section 20 of the relay destination system 3, and the data reception means 21.
The data is received by the data storage unit 25 and stored in the data storage unit 25 after passing through the storage unit access means 24 . Immediately after that, business processing department 2
2 reads the data originally sent from the relay source system 1 using the storage section access means 24 and performs various processing according to the input conditions of the instruction section 23.

When the communication operation between the data transmitting means 16 of the relay system 2 and the relay destination system 3 is abnormal, or when the data receiving means 21 in the relay destination system 3 is not operating, it is natural that the relay source system 2 to the relay destination system However, in this case, the data that is currently being sent or the data that is about to be sent is transmitted by data sending means 1.
6, the data is stored in the temporary data storage section 19 via the storage section access means 15. Here, data transmission means 16
requests the monitoring means 17 to perform fault recovery between the relay system 2 and relay destination system 3 or to monitor the start-up of the data receiving means 21, and waits for the next data transmission request from the data receiving means 14.

Relay system 2 to relay destination system 3 by monitoring means 17
During failure recovery or when the data reception 21 starts up, the monitoring operation is performed at intervals of n minutes, and the time interval value is stored in the data storage unit (for management) 19 and can be changed arbitrarily. There is.

In the monitoring operation, relay system 2 to relay destination system 3
If it is confirmed that the data reception means 21 has started up at 9, it is determined whether or not there is data stored in the data storage section 19 for - time, and if there is data, the data transmission means 16 is notified. In response, a data transmission request is made to the data relay destination system 3.

After that, the temporary data sent by the data transmitting means 16 is sent to the data receiving means 21 and the business processing section 22.
The failure recovery process is completed by performing various processes, and the relay system becomes a normal (empty) state.

〔Effect of the invention〕

As explained above, the present invention organically combines the function of receiving data from the relay source system and the function of transmitting data to the relay destination system, and also adds a monitoring function to it, thereby eliminating the need for manpower that may occur during data relay. It is highly effective in reducing the number of data corruption incidents due to intervention actions and operational errors, and in shortening business downtime through automatic recovery in the event of a failure.
