Abstract

PURPOSE:To analyze the relation between a fault and a data quickly and surely when a fault takes place by storing not only a communication data and a control signal but also an arrival time data and a timewise interval data. CONSTITUTION:A transmission reception data and a control signal are stored in a main memory 8. Simultaneously a clock means 9 detects the arrival time of the transmission reception data and it is stored in an arrival time data memory 10 time by time. Moreover, a rising and a falling of the transmission reception data are used as a trigger signal and timers 11, 12 detect data such as data timewise interval and interblock between data and the result is stored in the timewise interval data memory 14 via an OR circuit 13. Based on the stored data, arrival time data and a timewise interval data or the like, the relation between the fault and the data is analyzed and the result is displayed on a CRT or the like as required. Thus, the fault is analyzed accurately and quickly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data recording device for an online scope that stores not only data and control signals but also temporal data during data communication.

``Prior Art'' When data communication is performed between a main computer and a terminal computer, an online scope is combined for data communication maintenance. Previously, this online scope only stored data and control signals. ``Problem to be solved by the invention'' If a failure occurs by simply accumulating data and control signals as in the past, if data is accumulated for a long period of time, it will be difficult to analyze the relationship between the failure and the data. Another problem was that it took a long time. An object of the present invention is to obtain a device that can quickly and reliably analyze the relationship between failures and data by accumulating time data in addition to original data and control signals.

"Means for Solving the Problems" The present invention transmits and receives data between a main computer and a terminal computer, and stores these data in the main memory of an online scope.
a clock means for detecting the arrival time of the transmitted and received data; an arrival time data memory for storing the arrival time data of the clock means; a transmitted data timer for detecting the time interval of the transmitted data; It is equipped with a received data timer that detects a time interval, and a time interval data memory that stores time interval data between the transmitted data timer and the received data timer.6 "Operation" The clock means detects the arrival times of the transmitted data and received data and stores them in the arrival time data memory every moment.
In addition, time interval data is detected by a timer for transmission data and a timer for reception data using the transmission and reception data itself as a trigger signal, such as the rising and falling edges of the transmission data and reception data, and is stored in the memory respectively. When a failure occurs, the arrival time, data interval, and transmission time are calculated, and the relationship between the failure and the data is easily revealed. ``Example'' An example of the present invention will be described below based on the drawings. In the figure, (1) is a main computer, (2)... are terminal computers, and these are connected by a transmission line (3) and a reception line (4). These transmission/reception lines (3) (4) include maintenance lines (5) (6).
Online scope (7) is connected via.
This online scope (7) includes a main memory (8) for storing transmitted/received data and control signals, a clock means (9) for detecting the arrival time of the transmitted/received data, and a clock means (9) for detecting the arrival time of the transmitted/received data.
Arrival time data memory (
10), a transmission data timer (1l) that detects the time interval of the transmission data, a reception data timer (l2) that detects the time interval of the reception data, and these timers (11) (12). ) coupled to the OR circuit (13)
and a time interval data memory (14) for storing data of the transmission/reception timers (11) and (12). In the above structure, transmitted/received data and control signals are stored in the main memory (8). At the same time, the clock means (9) detects the arrival time of the transmitted and received data and stores it in the arrival time data memory (10) every moment. Furthermore, using the rising and falling edges of the transmitted and received data as triggers, the respective timers (11) and (12) detect data such as the time interval between data and the interval between data, and the OR circuit (l3) are stored in a memory (14) for time interval data.

Based on the data stored in this manner, arrival time data, time interval data, etc., the relationship between the failure and the data is analyzed and displayed on a CRT or the like as necessary. ``Effects of the Invention'' As described above, the present invention stores not only communication data and control signals, but also arrival time data and time interval data, so that when a failure occurs, the relationship between the failure and the data is maintained. This makes maintenance easier and allows for accurate and quick maintenance. Additionally, in data communication program development and simulations, it becomes easier to calculate data intervals and transmission times, which prevents discrepancies when actually set and used.
