Abstract

PURPOSE:To perform the economical monitor for the break of polling by checking the presence or absence of flags at each of plural memory areas of a memory means when the prescribed frequency of polling is counted by a counter. CONSTITUTION:When the polling signal is sent to one of plural terminal equipments 1 from a host 3, a control means 26 of a controller 2 sets a flag at a memory area of a memory means 25 corresponding to the relevant equipment 1. Hereafter the flags are successively set at the memory areas corresponding to other equipments 1 through the polling. While a counter 24 counts the polling frequency when the poling actions are started by the host 3. When the prescribed polling frequency is counted, it is checked whether the flags are set up at each memory area or not. Thus the presence or absence of the break of polling is checked. Then the polling can be monitored just by checking the presence or absence of the flags of each memory area via the counter 24 without using the same number of timers as the equipments 1.

[Industrial application field]

The present invention relates to a control device that monitors polling interruptions and includes a counting means for counting polling up to a predetermined number of times and a storage means for setting a flag for each polling in a storage area corresponding to a plurality of terminal devices.

[Prior Art] Recently, automatic deposit dispensing machines (Automatic deposit dispensing machines), which are terminal devices in online banking systems, have recently been introduced.
As the functions of automatic transaction devices (hereinafter referred to as ATV) such as teller machines (hereinafter referred to as ATMs) become more sophisticated and diversified, the amount of data that must be held in the devices increases, and large-capacity memory is required. I started to
In order to deal with this, as shown in Fig. 4, a specific number of ATMs are grouped together and a terminal control device is placed on top of the group.
ler: hereinafter referred to as T/C) 2a, 2b, - (hereinafter referred to as T
/C2a) to share common information and memory. That is, in the figure, 3a
14 is a line control device, 5.6 is a modem, and 7 is a branch device.

Further, as shown in FIG. 5, the T/C 2a includes a control unit 21 equipped with a memory for storing control programs and data, and timers 22a, 22b, . . . 1 corresponding to the ATMs la, lb, -, respectively. A line buffer 23 is provided.

For communication connection such as inquiry of data necessary for transactions from each ATM to the host 3a, the host 3a constantly sends an ATM to the host 3a at predetermined time intervals.
A polling signal is sent to b, -, the polling signal is received by T/C2a, and the polling signal (
(including destination data) is stored in the line buffer 23, and polling signals are sent to ATVla and lb based on the destination data.

sent to. On the other hand, when the polling signals for ATMs la, lb, - are sequentially received at the T/C 2a, the corresponding timers 22a, 22b, - start, respectively, and the next polling signal is activated until the predetermined time is counted. It monitors what is sent to ATM la, lb, ....

If polling is not sent even after a predetermined period of time has elapsed, it is recognized that polling has been disconnected.

If polling is disconnected, transactions cannot be made, so ATM
The corresponding devices of 1 a + 1 b +... are suspended.

[Problem to be solved by the invention]

According to the above conventional method, polling management of multiple ATVs is performed by T/C from υ2, which requires multiple timers corresponding to the number of ATMs and their management, making the process complex and costly. There is a problem that it takes.

SUMMARY OF THE INVENTION An object of the present invention is to provide a control device that can economically monitor polling interruptions without using the corresponding number of timers in a terminal device.

[Means to solve the problem]

FIG. 1 is a block diagram of the principle of the present invention.

In the figure, 1 is a plurality of terminal devices, 2 is a control device, 3 is a host, 24 is a counting means for counting the number of times the host 3 polls the plurality of terminal devices 1 up to a predetermined number of times, and 25 is each of the plurality of terminal devices 1. 26 is a control means that sets a flag in the corresponding storage area of the storage means 25 when the host 3 polls each of the plurality of terminal devices 1.

Therefore, when the counting means 24 counts a predetermined number of times of polling, it is configured to check whether a flag is set in each of the plurality of storage areas of the storage means 25.

[Effect]

When a polling signal is sent from the host 3 to any one of the plurality of terminal devices l, the control means 26 of the control device 2 sets a flag in the storage area of the storage means 25 corresponding to the terminal device l. By sequentially polling other terminal devices l, flags are set in the corresponding storage areas.

On the other hand, when polling from the host 3 is started, the counting means 24 counts the number of polling times, and when a predetermined number of times is counted, it is checked whether a flag is set in each of the plurality of storage areas and polling is started. Detect the presence or absence of a disconnection.

In this way, polling can be monitored by simply checking the presence or absence of a flag in each storage area using the counting means 24 without using timers for the number of terminal devices l, which simplifies the process. Moreover, cost can be improved.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. The same reference numerals refer to the same objects throughout the design. In FIG. 2, parts corresponding to those in FIG. 1 are shown surrounded by a dashed line.

In FIG. 2, the T/C 20a is the T/C 20a explained in the conventional example.
/C2a's timers 22a, 22b, -, polling counter 24a instead of the timer management program
.

Monitoring data memory 25a and polling control unit 26a
It is equipped with

The polling counter 24a includes a setting section 24b in which a predetermined number of times N is set, and is ATMIa from the host 3a.

The number of polling times for lb, --- is counted up to a predetermined number N.

The monitoring data memory 25a corresponds to ATMla, 1b, -=, respectively, and has storage areas AI, A2 . - has.

The polling control unit 26a sends data from the host 3a to the ATM 1a.
+1b+'--., the corresponding storage areas At, A2 .・When the flag is set to - and the polling counter 24a counts the predetermined number N of polling, the storage area of the monitoring data memory 25a is
1. A2. - The presence or absence of each flag is checked, and the ATM corresponding to the storage area without the flag recognizes that polling has been disconnected.

Since it has such a configuration and function, the operation will be explained with reference to the flowchart in FIG. 3.

■First, the polling signal from the host 3a is sent to the T/C 20.
Receive at a.

■Polling signal to line buffer 23 (for example, destination AT
M1a) is stored.

■Send a polling signal to ATMla according to the destination data.

(2) A flag is set in the storage area A1 of the monitoring data memory 25a based on the destination data.

- Add 1 to the polling counter 24a.

- When polling continues and the count of the polling counter 24a reaches a predetermined number N, a count-out signal is sent to the polling control unit 26a, and the polling control unit 2
6a is all storage areas At, ^2. Check the presence or absence of the − flag.

■Recognize the ATM corresponding to the storage area where the flag is not set as polling disconnection.

■Instruct the relevant ATV to suspend trading.

In this way, there is no need to equip the control device with a number of timers corresponding to the number of terminal devices to perform polling management, which simplifies processing and improves costs.

Although the above example describes the case of an ATV as a terminal device, it is of course applicable to other automatic transaction devices such as automatic teller machines, and in general, multiple It can be applied to a system that polls terminal devices.

〔Effect of the invention〕

As explained above, according to the present invention, a counting means for counting the number of polling up to a predetermined value and a storage area in which a flag is set corresponding to a polled terminal device are provided.
Since polling interruption can be recognized by checking the presence or absence of a flag during countout, the complicated processing that required each terminal device to have a timer and was managed has been improved to a simple processing, and the cost is also reduced. This has the effect that it is possible to improve the
