Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a main processing device, a slave processing device, and an external connection device, and provides communication between the main and slave processing devices and between the main and slave processing devices and the external connection device. Therefore, the present invention relates to a diagnostic method that does not reduce transaction processing efficiency in a system that exchanges information, particularly when the transaction frequency is unpredictable due to high traffic.

High reliability is required in the sale and refund systems for public competitions such as horse racing, bicycle races, auto races, and boat races. It is activated every time (for example, several minutes) and executes prescribed diagnostic processing between the main and slave processing devices and between the main and slave processing devices and externally connected devices. Therefore, it is necessary to process transactions in the time remaining after the periodic diagnosis is performed within the predetermined period of time. For this reason, when the frequency of transactions is high, transaction waiting occurs and processing efficiency decreases. Frequent periodic diagnostics are necessary to detect failures early. For example, if an external connection device is out of order, it is necessary to reconnect the refund terminal connected to it to another external connection device to eliminate the problem. It is for this purpose.

For example, the frequency with which refunds occur is unpredictable and uneven. For this reason, conventional methods have the disadvantage of requiring the use of systems that are expensive but have a processing speed that is significantly faster than the amount of traffic. In addition, in the case of a system where the processing speed is close to the amount of traffic, it is impossible to predict the unevenness of the frequency of transactions, so it is necessary to use methods such as considerably lengthening the diagnostic cycle or dividing the diagnostic items, which requires processing at the expense of reliability. The disadvantage is that the response to route abnormalities is delayed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a diagnostic method that can quickly detect abnormalities in processing routes while increasing transaction processing efficiency even in systems with slow processing speeds and close to traffic volumes.

In order to achieve the above object, the present invention comprises a dual system consisting of a main processing device and a sub-processing device, and an external connection device. In a system in which information is exchanged between externally connected devices, a periodic diagnostic routine is provided for each externally connected device, between the main and subprocessing devices, and between the main and subprocessing devices, and for each externally connected device. A periodic diagnosis routine is started at each activation cycle determined by the timer, and the periodic diagnosis routine is started in a prescribed order, and at that time, transactions are executed in the prescribed order. If a transaction occurs in the externally connected device during the diagnosis, the diagnosis is interrupted, the next empty externally connected device is diagnosed in the order, and all the externally connected devices are diagnosed. Diagnosis is performed between the main and slave processing units when no transaction occurs in the externally connected device, and when a transaction occurs in any one of the externally connected devices, the diagnosis between the main and slave processors is performed. The system is characterized in that diagnosis is interrupted, the activation period of the regular diagnosis routine is shortened to about a few seconds, and abnormalities in the processing route can be detected quickly while improving transaction processing efficiency.

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

Fig. 1 is a conceptual diagram of this system, Fig. 2 is a block diagram centered on transaction detection in an embodiment of the invention, Fig. 3 is a time chart for diagnosing the embodiment of the invention, and Fig. 4 is a diagram. 1 shows a flowchart of diagnosis according to an embodiment of the present invention.

In the figure, 1 is the main processing unit, 2 is the sub-processing unit, and 3-
1, 3-2 are external connection devices, 4-1 to 4-n, 5
-1 to 5-n are terminals, 6 is a timer, 7 is a regular diagnosis routine, 8 is a transaction detection unit, 9 is an external connection control unit, 10 is an external connection device A device (hereinafter referred to as A device), 11 is the B device (hereinafter referred to as B device) which is an externally connected device; 12 and 13 are the statuses indicating the occurrence of a transaction; T is the activation cycle of the periodic diagnosis routine; and 14-1 is the A device 10 and the main processing device 1 or 14-2 is a periodic diagnostic routine between the B device 11 and the main processing device 1 or the secondary processing device 2;
-3 is a periodic diagnosis routine between the main processing device 1 and the slave processing device 2, 15-1 and 15-2 are the A device 1
0, indicates the occurrence of a transaction from the B device 11.

This system consists of terminals 4-1 to 4 as shown in Figure 1.
- When a transaction occurs from the terminals 5-1 to 5-n, it is transmitted through the external connection device 3-1, and when a transaction occurs from the terminals 5-1 to 5-n, it is transmitted through the external connection device 3-2. Information is sent to the processing device 2 for processing. The periodic diagnosis routine 7 is provided in the main and slave processing units 1 and 2, and normally the periodic diagnosis routine 7 of the main Periodic diagnosis between processing devices 1 and 2 is being performed.

If the processing route with the external connection device 3-2 is abnormal, for example, connect the terminals 5-1 to 5-n to the external processing device 3-1 so that the terminals 5-1 to 5-n can also be used. This prevents problems from occurring. Since the processing devices 1 and 2 have dual operation, even if one of them is abnormal, the other can perform the processing.

Conventionally, regular diagnostics were performed at predetermined intervals (several minutes) regardless of the occurrence of transactions from terminals 4-1 to 4-n and 5-1 to 5-n, and transactions were processed using the remaining time. Therefore, if the frequency of transactions was high, transaction waiting would occur and processing efficiency would decrease. In the case of the present invention, as shown in FIG. 2, a transaction detection section 8 composed of a logic circuit is provided next to the external connection control section 9, and when a transaction occurs from the A device 10 or the B device 11, the external connection is controlled. Part 9
This transaction information is sent to the transaction detection unit 8, and if a transaction occurs from device A 10, flag A is set in status 12, for example, and if a transaction occurs from device B 11, flag A is set in status 13. Set flag B.

As a result, the main and slave processing devices 1 and 2 are connected to the A device 1.
The occurrence of a transaction from the 0 and B devices 11 is recognized. The periodic diagnosis routine 7 is a periodic diagnosis routine 14-1 between the A device 10 and the main processing device 1 or the sub-processing device 2, and a periodic diagnosis routine 14-1 between the B device 11 and the main processing device 1 or the sub-processing device 2. −
2. It consists of a periodic diagnosis routine 14-3 between the main processor 1 and the slave processor 2.

Also, the timer 6 is used to shorten the activation cycle T of the periodic diagnosis (to about several seconds). As a result, Fig. 3, Fig. 4
As shown in the figure, when a transaction occurs 15-1 from the A device 10 during diagnosis in the periodic diagnosis routine 14-1, the status 12
Since the flag becomes A, the main processing unit 1 or the slave processing unit 2 detects this, bypasses the A device diagnosis, and processes the transaction. Also, during the periodic diagnosis routine 14-2, the B device 1
If a transaction from 15-2 occurs, the flag of the status 13 becomes B, so the B device diagnosis is bypassed and the transaction is processed in the same way as above.

For example, when a transaction occurs 15-1 from the A device 10 as shown in A during diagnosis in the periodic diagnosis routine 14-3, the flag of the status 12 becomes A, so the main/slave processing device processing the transaction, bypassing the intermediate diagnostics.

If the transaction 15-1 or 15-2 occurs before the diagnosis time of the periodic diagnosis routine 14-1 or 14-2 and the periodic diagnosis routine processing time comes during transaction processing, this will be handled. The processing of periodic diagnosis 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, periodic diagnosis is performed during transaction processing. When the time for routine 14-3 comes, the processing of periodic diagnosis routine 14-3 is bypassed.

During the periodic diagnosis routine 14-1, no transaction occurs from the A device 10, and while the periodic diagnosis routine 14-2 performs the diagnosis, no transaction occurs from the B device 11. The A device 10 and the B device 11 do not occur and the diagnosis is performed in the periodic diagnosis routine 14-3.
If there are no more transactions than
Perform the usual diagnosis as shown in C and D. 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 close to the amount of traffic can process it, and can be configured as an inexpensive system.
