Abstract

PURPOSE:To detect the abnormality quickly while improving the processing efficiency, by by-passing the diagnostic route between an external connection device, where a transaction is generated, and a processor, to open the processing route and diagnosing idle routes. CONSTITUTION:A detector 8 is provided following a controlling part 9; and when a transaction is generated, a flag is set in a status 12, and processor 1 and 2 recognize it. A start period T of the periodic diagnosis is shortened by a timer 6. If a transaction 15-1 is generated in an A device 10 during the diagnosis on a periodic diagnosis routine 14-1, the flag of the status 12 is detected by the processor 1 or 2 to by-pass the diagnosis for the A device 10, and the transaction is processed. Similarly, processings for a corresponding routine 14-1 or 14-2 is by-passed when the time for the periodic diagnosis routine processing comes during the processing of a transaction 15-1 or 15-2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is constituted by a main processing device, a sub processing device, and an external connection device, and a connection between the main and sub processing devices and between the main and sub processing devices and a cough external connection M device. The present invention relates to a diagnostic method that does not reduce transaction processing efficiency in a system that exchanges information through communication, especially when there is high traffic and uneven transaction frequency.

In the sale or refund system for public competitions such as horse racing, bicycle racing, auto racing, and boat racing, the processing equipment for horse owners and subordinates that requires high reliability is dual-equipped, and periodic diagnostics are carried out at specified times regardless of the frequency of transactions. It is activated every few minutes (for example, several minutes) and executes prescribed diagnostic processing between the main and slave processing units and between the main and slave processing units and externally connected devices. Therefore, it is necessary to process the transaction in the time remaining after the periodic diagnosis is performed within the specified time period. Therefore, when the frequency of transactions is high, transaction waiting occurs and processing efficiency decreases. Frequently performing periodic diagnostics will help you find failures early. For example, if an external connection device is out of order, you will need to replace the refund terminal connected to it with another external connection device to eliminate the problem. This is because there is.

For example, the occurrence of refund #JI is unpredictable and uneven. For this reason, conventional systems have the disadvantage of requiring the use of systems that are expensive but have significantly faster processing speeds than the amount of traffic. In the case of a system where the text processing speed is close to the traffic volume, it is impossible to predict the unevenness of the frequency of transactions, so it is necessary to extend the diagnostic cycle or divide the diagnostic items by a large amount, thereby sacrificing reliability. The disadvantage is that the response to route abnormalities is delayed.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by making transactions possible even in systems with slow processing speeds and close to the amount of traffic.
To achieve the above object, the present invention provides a diagnostic method that can quickly detect abnormalities in the processing route while reducing processing efficiency. , the diagnostic route between the external connection device where the transaction is occurring and the main/slave processing device will be detoured, the transaction processing route will be opened, and transaction waiting will be resolved.Transaction slave processing By diagnosing between devices or between the main and slave processing devices when no transactions are occurring on any externally connected devices, it is possible to quickly detect abnormalities in the processing route while maintaining transaction processing efficiency. shall be.

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

If the processing route with the external S connection device 3-2 is abnormal, connect the terminals 5-1 to 5-n to the external processing device 3-1 so that the terminals 5-1 to 1 can also be used. This prevents problems from occurring. Processing devices 1 and 2 operate in a natural manner, so even if one is abnormal, the other can handle the processing.0 Conventionally, terminals 4-1 to 4-n, 5-1 to 5
-Regardless of the occurrence of transactions from n, periodic diagnosis is performed every predetermined time (several minutes), and transactions are processed using the remaining time, so if transaction thief occurs frequently, transactions may be waited for and processed. Efficiency was decreasing. In the case of the present invention, as shown in FIG. 2, a transaction detecting section 8 configured with an externally connected control section 90 and a logic circuit is provided, and when a transaction occurs between the A device 10 and the B device 11, an external S connection is provided. This transaction information is sent to the transaction detection unit 8, and if a transaction occurs from device A, flag A is set in status 12, and if a transaction occurs from device B, flag A is set to status 13. For example, set slug B.

As a result, the master and slave processing devices 1.2 recognize the occurrence of a transaction between the A device 10 and the B device 11. The periodic diagnosis routine 7 is a periodic diagnosis routine 14-11B device k' between the A device lO and the main processing device 1 or the slave processing device 2.
A periodic diagnosis routine 14-2 between the main processing device 1 and the main processing device 1 or the slave processing device 2, and a periodic diagnosis routine 14-3 between the main processing device 1 and the slave processing device 2.

Also, the timer 6 is used to shorten the activation cycle T of the periodic diagnosis (to about several seconds). As a result, as shown in FIG. 3 and FIG. 4, during the periodic diagnosis routine 14-1,
When there is a transaction 15-1 from the device 10, the flag of the status 12 becomes A, so the main processing device 1
Alternatively, the slave processing device 2 detects this, bypasses the AIIcfIt# disconnection, and processes the transaction. Also, during the periodic diagnosis → 2nd 14-2, the B equipment was
If a 15-2 transaction occurs, the flag of the status 13 becomes B, and the transaction is processed by bypassing the B device diagnosis in the same way as described above.

For example, when a transaction is generated 15-1 from the A device 10 as shown in A while the periodic diagnostic routine 14-3 is disconnecting, the flag of the status 12 is set to A.
Therefore, the transaction is processed by bypassing the diagnosis between the main and slave processing units. Furthermore, if transaction 15-1 or 15-2 occurs before the diagnosis time of periodic diagnosis routine 14-1 or 14-2, When the periodic diagnostic routine processing time comes during transaction processing, the corresponding periodic diagnostic routine 14-
1 or 14-2 is bypassed, and since transaction 15-1 or 15-2 occurs before the diagnosis time of periodic diagnosis routine 14-3, the periodic diagnosis routine 14-3 time occurs during transaction processing. When this occurs, the processing of periodic diagnosis routine 14-3 is bypassed.

Periodic Diagnosis Routine 14 - A to the lock where the IK is being diagnosed.
No transactions occur from device 1li10,
Also, while the periodic diagnosis routine 14-2 is performing the diagnosis, no transaction occurs in Bi[11], and while the periodic diagnosis routine 14-3 is performing the diagnosis, the A device 10 and the B device 11 If no transactions occur, normal diagnosis is performed as shown in Sections 1, 2 and 2. As a result, the efficiency of transaction processing is not reduced, and the periodic diagnosis cycle is short, so that abnormalities can be detected quickly. Therefore, even a system with a slow processing speed and close to the amount of traffic can process it.

As described in detail above, according to the present invention, an abnormality in a processing route can be quickly detected while improving transaction processing efficiency, so that even a system with a slow processing speed and a similar traffic volume can process the transaction, resulting in an inexpensive system configuration.
