JPH02205939A - System for informing fault of on-line terminal - Google Patents

Abstract

PURPOSE:To continue an on-line transaction job by comparing the number of faults occurring in an on-line terminal with a regulation value, and informing the fault to a host computer via a line only when it is less than the regulation value. CONSTITUTION:When a fault signal inputted from a signal line 1 is detected at a fault detecting part 2, a detecting signal is immediately outputted to a signal line 3, and is counted and recorded on a counter 4. A value set on the counter 4 is compared with the content of a regulation value register 5 at a comparison part 6, and a less regulation value signal on a signal line 7 is activated only when the former is less than the regulation value. An AND gate 8 transmits the detecting signal on the signal line 3 to a fault informing part 10 on a signal line 9 only while when the less regulation value signal on the signal line 7 is activated. In such a way, influence on a regular on-line transaction job can be evaded even when a large number of on-line terminals are operated and also, a large number of faults occur.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a fault notification method for an online terminal, and in particular,
This invention relates to reducing the load required to handle host computer failures in systems with a large number of terminal failures.

(Prior Art) Conventionally, in the fault notification system for online terminals, a device is configured of a detection means for detecting a fault, a fault notification means for notifying the outside of the fault, and a trap. It was designed to send signals to the outside as many times as the number of failures detected, and to notify the outside of the failure.

(Problems to be Solved by the Invention) In the above-mentioned conventional failure notification system for online terminals, it is difficult to monitor the failure by a host computer through a line, as in online terminals such as automated teller machines in banks. is common.

This failure monitoring is done during the regular business of online transactions. On the other hand, failure notifications are also sent on the terminal side between online transactions.

Therefore, all the number of failures detected on a terminal are notified to the host computer through the line, so if there are a large number of online terminals and a large number of failures, the load on the host computer itself and the line will be extremely high. 5. There is a drawback that it affects the original on-twin transaction business.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by comparing the number of failures that occur in an online terminal with a specified value, and only when the number is less than the specified value, to notify the host computer of the failure through a line. It is an object of the present invention to provide a fault notification method for an on-twin terminal configured so as not to cause any adverse effects.

(Means for Solving the Problems) The fault notification method of the on-twin terminal according to the present invention includes a fault detection section, a fault notification section, a counter, a specified value register,
It is configured to include a comparison section and an AND gate.

The fault detection section is for detecting faults. !
The notification section is for notifying the outside of a failure.

The counter is for counting and storing the number of detected failures.

The specified value register is used to set a specified value that determines the allowable number of failures.

The comparison section is for comparing the contents of the counter and a specified value.

The AND gate is used to gate only the number of failures that are less than the specified value even if the failure detection section detects a number of failures that are equal to or greater than the specified value, and to provide the gated results to the failure notification section.

(*Example) Next, the present invention will be explained with reference to the drawings.

The 11th iW is a block diagram showing an embodiment of a fault notification method for an online terminal according to the present invention.

In FIG. 1, 2 is a failure detection unit, 4 is a counter, 5 is a specified value register, 6 is a comparison unit, 8 is an AND gate, and 10
is the fault notification section.

When the failure signal inputted from the signal @1 is detected by the failure detection section 2, the detection signal is immediately output onto the signal line 3 and counted and recorded in the counter 4.

The value set in the counter 4 is compared with the contents of the specified value register 5 in a comparator 6, and only when the former is less than the specified value, the less than specified value signal on the signal line 7 is activated.

The AND gate 8 transmits the detection signal on the signal line 3 as a detection signal to the fault notification unit 10 via the signal line 9 only during the period when the less than specified value signal on the signal line 7 is activated. When a detection signal is input from the signal line 9, the failure notification unit 10 receives the detection signal from the signal line 9.
Immediately output an external notification signal onto signal line ll.

When the value of the counter 4 is equal to or greater than the value of the specified value register 5, the comparison unit 6 activates the less than specified value signal on the signal line 7, and the AND gate 8 suppresses the detection signal on the signal line 3.

Therefore, in this case, no detection signal is generated on the signal line 9, and the fault notification section 10 does not output an external notification signal on the signal fill.

In this embodiment, the counter 4' is set by simple addition calculations, but it is also possible to provide a time-varying function that clears the counter 4 if no detection signal is input from the signal line 3 within a certain period of time. good.

(Effects of the Invention) As explained above, the present invention compares the number of failures that occur in online cohesion with the number of specified values, and only when the number is less than the specified value, notifies the host computer of the failure through one line. Therefore, in an online terminal failure monitoring system where the number of terminals and the number of failures are large, online trading operations can be satisfactorily continued by simply manipulating the specified values.
