Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal device glue coverage processing method in a totalizer system, and in particular, the operating state of the terminal device is divided into a plurality of parts, and the operating state is displayed at the time of a momentary power interruption or power outage. In addition, the final processing message processed by the center computer (CPU) immediately before a power outage, etc. is printed as a copy after the power is restored, and the CPU subtracts the message by referring to the above operating status display and copy printing information. The present invention relates to a cover IJ processing method that determines whether or not to execute processing.

In a vote aggregation system (totalizer system) for horse racing tickets, boat tickets, etc., a large number of voting ticket vending machines, refund machines, or dual-purpose machines are connected to a central computer (hereinafter referred to as CPU) via a transmission control circuit.

In such a system, the CPU aggregates the voting information input from each terminal machine for each horse/group number, calculates the multiplier, checks the input voting information, and also calculates the refund amount. etc. are controlled.

Therefore, if the ticket information issued from the vending machine and the voting information tallied by the CPU do not match, then the
The PU will have under- or over-accumulated, and the function of the totalizer system will be completely impaired.

This is exactly the same even when the amount refunded from the refund machine and the amount processed as refund money by the CPU are different.

That is, in the totalizer system, it is necessary that the information output from each terminal always matches the data processed by the CPU.

Now, if we consider the causes of the above-mentioned discrepancy, we can think of momentary interruption or power outage of the terminal power supply.

By the way, the release machine in the totalizer system etc.
Terminal devices such as refund machines use volatile memory as data memory, that is, memory whose stored data disappears in the event of a power outage. If a power outage occurs, communication data will be lost and the information output from each terminal (
It is not possible to determine whether or not the sales result information) and the CPU processing (aggregation) results match.

For this reason, the operating status of each terminal is divided into multiple parts.
An operating state display method has been proposed in which the operating state at the time of a momentary power interruption or power outage is displayed, and filing data of the CPU is corrected based on this display.

However, as will be described later, this method has the disadvantage that it lacks accuracy because it displays the state determined by the terminal device independently without regard to the processing operations of the CPU immediately after a power outage.

FIG. 1 is a block diagram of a totalizer system to which the present invention can be applied, in which 1 to 1n are operating consoles for terminals such as voting ticket vending machines, 2 is a CPU, and 3 and -3n are for controlling each terminal and controlling each terminal. This is a transmission and control circuit that controls data transfer between the terminal and the CPU, and 1 and 3 constitute one terminal.

FIG. 2 shows the operating state when a voting ticket is sold from a vending machine, with time plotted on the horizontal axis, and the voting ticket is sold according to the following sequence.

Note that the numbers in the figure correspond to the sequences below.

■ The operator inputs the voting information provided by the person wishing to vote using the keys on the console 1.

The voting information is stored in a register inside the vending machine and displayed on a display section (not shown).

■ After inputting all voting information from one person who wishes to vote, the operator presses the transmission key on the operation desk.

(2) Voting information in the register is transmitted to the CPU under the control of the transmission and control circuit 3.

■ When the CPU receives the above voting information, ■ Checks whether the voting information matches the predetermined fort and whether there is a corresponding horse/group number, etc. O Totalizes the voting amount for each horse/group number
Performs processing for displaying Otsuzu.

(2) After completing the above-described predetermined processing, the CPU sends a ticket issuance permission signal and answers back the total amount, etc. to the vending machine.

■ When the vending machine receives the ticket issuing permission signal, it sends an ACK to the CPU.
It sends signals and processes the total amount, etc.

■ If the CPU does not receive an ACK signal even after 10m5ec has elapsed after sending the ticket issuing permission signal, it sends an EoT (End Op Transmission) signal to the vending machine, clearing all internal states of the vending machine, and inputting data from the vending machine. Based on this, all CPU processing results will be canceled and the service will proceed to the next selling machine.

On the other hand, if a signal is received from the vending machine within 10 m5ec but this signal is not an ACK signal, the CPU sends a NACK signal back to the vending machine and requests the vending machine to send an ACK signal again.

If the CPU receives the ACK signal within 10m5ec, the
The PU polls the next vending machine for service without canceling the processing result, and reaches 10m5eC.
If it does not receive an ACK signal within that time, it will issue an EoT signal,
Cancellation processing is performed in the same manner as described above.

■If the vending machine does not receive either a NACK signal or an EoT signal from the CPU even after 15m5ec has elapsed after sending out the ACK, the vending machine control section instructs the printing machine to start issuing tickets, and ■Prints voting information on the designated ticket surface. .

Now, the conventional operating state display method roughly divides the sequences of each terminal operating state in appeals (2) to (3), and states 1 and 2.
At the same time, state 1 is made into a sequence ■~■, state 2 is made into a sequence ■~■, and in state 1, subtraction processing is not required at the time of power restoration, and in state 2, subtraction processing is required at restoration time. It is.

However, subtraction processing may be necessary even in operating state 1, and in such a case, in the conventional operating state display method, the total result by the CPU and the sales result will not match.

The reason for this will be explained below.

Now, considering the case where there is a momentary power outage or power outage of the terminal device in each of the above sequences, in state 1 (■), voting information is not sent to the CPU and no voting ticket has been sold, so the output from the vending machine is There is no inconsistency with the processing results of the CPU.

・・・・・・・・・■～■ of subtraction processing unnecessary state 1, that is,
If the terminal loses power while the CPU is processing, this power outage will cause the CPU to
The CPU is detected and interrupts, and the CPU shifts to the power outage program and invalidates the voting information currently being processed.

As a result, even if there is a momentary power outage or a power outage in states (1) to (2), no contradiction will occur because no voting ticket has been issued from the vending machine.

......When a power outage occurs in state 1 (■) where no subtraction is required, ■CPU generates EoT and the processing results are all canceled.
It is difficult to determine whether the K signal is received and the service is started on the next machine without any cancellation.

On the other hand, since voting tickets are not sold from the vending machine, taking this into consideration, in the case of ■, the sales result and the tally result match, but in the case of @, the CPU over-tallyed. , the total amount in the operator's hand does not match the total amount for each vending machine stored in the CPU, and the subtraction result of the multiplication factor also does not match the actual amount, so the function as a totalizer is lost.

That is, if a power outage occurs in state 1 (■), the sales results and the tally results may or may not match.

Next, when a power outage occurs in state 2, the tickets have not yet been printed and issued by the printing machine, so the sales results and the tally results do not match.

Therefore, in state 1 (■) and state 2, there is a possibility that the CPU is not performing an accurate totalizer when there is a power outage or a momentary interruption of the power supply, and it is possible that the CPU is not performing an accurate totalizer. It becomes necessary.

Now, in the conventional operating state display system, subtraction processing is performed only when a power outage occurs in state 2, and even if a power outage occurs in state 1, sales operations continue without any subtraction processing.

As a result, in the past, accurate totalizers were not possible.

Therefore, even in state 1, if the recovery process is changed to determine whether subtraction processing is necessary and start sales operations after recovery, even if the operating state at the time of power outage was state 1, state 2 In any case, it is necessary to perform a process of matching the tally results with the sales results, which requires frequent operations by the operator.

The present invention aims to eliminate the above-mentioned drawbacks, and divides the operating state of the terminal into states 1 and 2. State 1 is defined as ■~■ above, state 2 is defined as ■~■, and state 1 is divided into states 1 and 2. When a power outage occurs and the power is restored, it is possible to sell products immediately without any processing, such as subtraction processing, and only in state 2, when a power outage occurs and the power is restored, processing is required to match the tally results with the sales results. This simplifies the process for the operator.

Then, when the power goes out in state 2 and is restored, even more CPU
The recovery process is performed by printing out a copy of the message immediately before the power outage on the make-shift vending machine side, and referring to the printed copy, deciding whether to perform subtraction processing or not, and performing the vending operation.

The present invention will be described in detail below with reference to the drawings.

FIG. 3 is a block diagram for realizing the recovery processing method according to the present invention, where TU is a terminal device such as a voting ticket vending machine, CPU is a central processing unit on the center side, and INF is a CPU
An interface and control circuit between the U and the data controller and the operation of each part of the terminal, DET is a discrimination circuit that determines whether the CPU is operating or not, and FF1 is reset when the power is turned on, so there is no power outage. After the power is restored, the final processing message Ri RD is received from the CPU, and the flip-flop, FF2, which is reset by this, sends an RCAD signal from the selling machine to the CPU to request subtraction processing when the power is restored after the power outage.
, a flip-flop that is reset by the subtraction completion signal RCRD answered back to the vending machine when the CPU executes the subtraction process based on the request, SW is a switch for sending the subtraction request signal RCAD to the CPU, and INV is an inverter. , AG1 to AG2 are AND gates, RTC is a ticket printing device that prints voting information every time a voting ticket is sold, and the final processing message sent from the CPU when power is restored, and SR is a ticket printing device that prints the final processing message sent from the CPU when power is restored. A status register that stores the status, D
SP is a non-volatile operating state display element, for example an inverting display.

In the present invention, as described above, the operating state is divided into states 1 and 2, and states 1 to 2 are assigned to states 1 and 2 to 2 are assigned to states 2.

The current states 1 and 2 of the vending machine are stored in the state register SR, and the states are displayed on the reverse display DSP.

Now, if a power outage occurs in state 1, state 1 will be displayed on the reverse display, and in this case, the CPU's tally result and the sales result will match, and subtraction processing, etc., will not be necessary.

After the power is restored, both FF1 and FF2 are reset. Therefore, when the judgment circuit DET detects that the CPU is operating, the AND gate AG1 opens and sends a power restoration notification to the CPU via the interface INF as well as the information immediately before the power outage. A final processing message request signal RiAD is sent.

When the CPU receives this RiAD signal, it answers back the final processed message to the terminal.

When the interface and control circuit receives the final processing message, it inputs the message to the receipt printing device to print a copy and sets the flip-flop FFi.

Now, as mentioned above, if a power outage occurs in state 1, there is no need to perform any subtraction, and without operating the subtraction key SW,
Start the next sales operation.

Next, a power outage occurs in state 2, and when the power is restored, the final processing message is first printed by the receipt printing device and the flip-flop F
1 is set.

When a power outage occurs in state 2, subtraction processing is necessary in most cases, but there are cases where subtraction processing is not necessary.

Therefore, the operator first displays state 2 on the reverse display DSP.
If it is confirmed that this is the case, the CPU refers to the final processing message printed by the receipt printing device.

By looking at this copy printout, it can be easily determined whether or not the totalization process has already been performed by the CPU.

Therefore, if the counting process has already been performed, the subtraction SW is operated to cause the CPU to execute the subtraction process.

As a result, the logic of the anime game 1-AG2 is cleared, and the recovery subtraction request signal RCAD is notified to the CPU via the interface circuit INF.

When the CPU receives the R and CAD signals, it subtracts the latest input bed information from the total result to make the calculation result match the sales result.

When this subtraction is completed, the CPU answers back a recovery subtraction completion signal RCRD to the vending machine, and the flip-flop FF2 is set, thereby causing the vending machine to start the next vending operation.

Incidentally, if the aggregation process has not been performed yet, it is possible to proceed to the sales operation without operating the subtraction key.

As described above, according to the present invention, it is possible to display the operating state and decide whether or not to perform subtraction processing by referring to the receipt depending on the operating state, and in state 1, subtraction processing is not performed. It is no longer necessary at all, and it has become possible to perform accurate and easy-to-operate cover processing.

Furthermore, the subtraction process can be performed simply by operating the subtraction key after power is restored, making the recovery process even easier.

In the present invention, the terminal device has been described as a vending machine, but the present invention is not limited to this, and can of course be applied to a refund machine, a dual-purpose machine, etc.
