DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication error processing method implemented in a system for comprehensively managing a pachinko machine installed in a pachinko hall, for example.

[0002]

2. Description of the Related Art In a pachinko hall or the like, information on pachinko machines (for example, pachinko machines) is transmitted from a communication terminal provided at each pachinko machine.
The number of times the ball passed the pachinko machine start chucker,
In order to obtain the number of jackpots and control the communication terminal and the pachinko machine, each communication terminal is connected to a router via a communication path, and the router communicates with a communication interface provided on the computer, and the computer communicates. A data communication system for acquiring information from an interface is provided. In data communication, a communication error may occur due to noise or the like generated in a hall, and communication control has been conventionally performed to cope with such a communication error. The communication error includes, for example, a collision between a communication request from the communication interface and a reply from the router, a reply from the router to the communication request from the computer for a certain period of time, or a reply from the router. In some cases, the data does not meet predetermined format requirements.

FIG. 4 is a flowchart showing a conventional communication control. The communication interface (I / F) determines which of the plurality of routers to communicate with (step S11). Data transmission / reception is performed with respect to the determined router (steps S12 and S12).
13). Next, it is determined whether or not an error has occurred in the data transmission / reception (step S14).
The communication interface fetches the received data into the memory and performs a predetermined process (step S15), and performs a process of selecting the next router (step S11). on the other hand,
If an error has occurred, communication with the router is stopped, and error information is generated (step S16).

On the computer (PC) side, error information is periodically checked. When an error occurs, an error is displayed on the computer screen or a warning sound is issued to notify the administrator of the occurrence of the error. I do. When a predetermined process for the error is performed, the computer issues a communication restart command to the communication interface. The communication interface determines whether a communication restart instruction has been issued (step S17), and upon receiving the restart instruction, restarts communication with the router again (step S18, step S12). The communication processing described above is an example of the conventional communication error processing, but basically, the conventional processing temporarily stops communication with the router every time an error occurs, or after the error processing. It was to resume communication with the same router again.

[0005]

As described above, in the conventional communication error processing method, communication with the router is stopped every time a communication error occurs, and communication with the same router is restarted. In an increasing number of communication places, a substantial transmission speed of information is reduced, and there is a disadvantage that one communication error process hinders real-time communication of the entire system.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a communication error processing method capable of minimizing communication delay.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a communication error processing method of the present invention applied to a pachinko hall management system will be described below with reference to FIGS.

As shown in FIG. 1, in a pachinko hall, a communication terminal 2 provided on each pachinko machine 1 (for example, a data display device juxtaposed at a position above the pachinko machine 1; In order to obtain information on pachinko machines (for example, the number of times a ball has passed the start chucker of a pachinko machine, the number of jackpots, etc.) from a pachinko machine, and to control the communication terminal 2 and the pachinko machine 1, Each communication terminal 2 and the first router 3 are connected by a communication path, and further, the first router 3 and the second router 4 are connected by a communication path, and the second router 4 and a communication interface ( The computer 5 communicates with the communication interface board 6 to obtain pachinko machine information from the communication interface 6, Data communication system adapted to control each device and are provided.

The first router 3 includes, for example, a register, a management table, and a timer, and takes in and stores pachinko machine information that changes depending on the use state of the pachinko machine.
The register includes a transmission buffer and a reception buffer, and temporarily stores communication data in a predetermined format. The management table stores pachinko machine information transmitted from each communication terminal 2. The timer measures the data communication time. Each communication terminal 2 includes a register for storing communication data in a predetermined format. Each register is
It is composed of a transmission buffer and a reception buffer. Each of these communication terminals 2 and the first router 3 are connected by a half-duplex communication path, and are connected to the communication terminal 2 indicated in the address area of the communication data stored in the transmission buffer of the register of the first router 3. The communication with the first router 3 is performed, and the communication is sequentially shifted to the communication with another communication terminal 2 at a constant cycle. Also, a plurality of first routers 3
Data communication is also performed between the router and the second router 4 in a constant cycle.

FIG. 2 is a block diagram showing a connection relationship between the computer 5, the communication interface 6, and the second router 4. The communication interface 6 includes a CPU 6a that performs various processes, a plurality of communication units 6b connected to the respective second routers 4, and a plurality of memory units 6c corresponding to the respective second routers 4. Also, the second router 4
Includes a CPU 4a that performs various processes, a communication unit 4b, and a memory unit 4c. The communication interface 6 transmits / receives data to / from the CPU 5a of the computer 5 via the memory unit 6c, and communicates with the communication unit 4b of each of the second routers 4 via the communication unit 6b at a constant period. Perform data communication.

FIG. 3 is a flowchart showing the contents of communication processing performed in the communication interface 6.
The communication interface 6 includes a plurality of second routers 4
It is determined which of the second routers 4 is to communicate with (step S1). Data transmission / reception is performed with respect to the determined second router 4 (steps S2 and S3). Next, it is determined whether or not an error has occurred in the data transmission / reception (step S4). If there is no error, the communication interface 6 sets “0” to the continuous error bit in the memory unit 6c, The error bit is cleared to 0 (step S5), and subsequently, the received data is taken into the memory and a predetermined process is performed (step S6). And
A process for selecting the next second router 4 is performed (step S
1).

On the other hand, when an error occurs, a counter (not shown) counts up,
It is determined whether there is a continuous error (step S7). In this embodiment, whether or not a continuous error has occurred is determined to be a continuous error when the error is repeated 10 times.
Also, errors include, for example, when a communication request from the communication interface collides with a reply from the router, when there is no reply from the router to a communication request from the computer for a certain period of time, or when data returned from the router is returned. May not satisfy a predetermined format requirement, but in this embodiment, a case where the above-mentioned errors are continuous is regarded as a continuous error.

If it is determined in step 7 that the error is not a continuous error, a process for selecting the next second router 4 is performed (step S1). On the other hand, if it is determined that there is a continuous error, "1" is set to the continuous error bit in the memory unit 6c (step S8), and a process of selecting the next second router 4 is performed (step S1).

On the computer 5 side, the continuous error bits are periodically monitored. When "1" is set in the continuous error bits, an error is displayed on the screen of the computer 5 or a warning sound is output. Notify the administrator of the occurrence of the error. At this time, the count value of the counter (not shown) may be read and displayed, or the communication interface 6 may communicate with the second router 4 in which the continuous error has occurred. It may be possible to perform control such as instructing not to do so.

According to the above configuration, when an error occurs in the data communication between the communication interface 6 and the second router 4, the communication interface 6 increments the counter and makes a communication with the next second router 4. Process to continue communication. Further, when a continuous error occurs in the data communication between the communication interface 6 and the second router 4, the communication interface 6 uses the memory 6 provided therein.
c stores information relating to an error (sets a continuous error bit to "1") and selects the next second router 4 to communicate with it, while the computer 5 reads out the memory 6c and When information about an error is stored, error processing is performed. Therefore, every time an error occurs, communication with the second router 4 is stopped,
It is possible to prevent such a disadvantage that communication with the same second router 4 is restarted after the error processing and communication is interrupted.

In this embodiment, an error occurs when the communication request from the communication interface collides with a reply from the router, and an error occurs when the return data from the router does not satisfy a predetermined format requirement. Although errors are excluded from continuous errors, the load on the computer 5 is reduced and the real-time property of data transmission / reception is more emphasized. However, these errors are also subjected to continuous errors. It may be. Further, a continuous error has been exemplified as the specific error, but the present invention is not limited to this. Further, the computer 5 may be configured to be able to arbitrarily access the memory of the communication interface 5 in order to check the above-mentioned error occurrence status.

[0022]

As described above, according to the present invention, communication with a peripheral device is stopped every time an error occurs, or communication with the same peripheral device is resumed after error processing. This has the effect that adverse effects such as delays can be prevented.
