Abstract

PURPOSE:To judge easily whether the understanding and transmission of the condition of the transmission is normal or abnormal by providing a displaying device having the display screen to display, by a displaying format corresponding to the central station and the terminal device, the transmitting procedure and the contents of the transmission executed actually between the central station and the terminal device. CONSTITUTION:The data transmitted from a center station 1 are sent through a communicating line 2 and a data transmitting analyzing device to a terminal device 5. The data transmitting analyzing device 3 receives the data on a communicating line 2, compares with the code of the standard transmitting procedure stipulated beforehand and is displayed in a displaying screen 4 as shown in a display 7. From when the data of an object are received, to when the response from the terminal device 5 for the data is received, the time also is measured, and the result shows displays 14 and 15 of the time on the displaying screen 4 together with the arrow mark to show the transmitting direction of the data. Hereinafter, displays 9-13 also are processed in the same manner, and printed out to a printer 6 in accordance with the necessity.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data transmission analysis device that analyzes transmission procedures, etc. when transmitting data using a communication line and displays the results on a display screen. .

[Conventional technology]

Figure 2 is a connection diagram between a conventional data transmission analysis device and a data transmission device. In the figure, 1 is a center station, 2 is a communication line,
3ill: a conventional data transmission analysis device; 4 is a display screen of a display device built into the data transmission analysis device 3;
5 is a terminal device, and 6 is a printer.

Next, the operation will be explained. Data transmitted from the center station 1 is transmitted to the terminal device 5 after passing through the communication line 2 and the data transmission analysis device 3. In response, the terminal device 5 transmits a response to the data sent from the center station 1 to the center station 1 via the communication line 2 and the data transmission analysis device 3. The above procedure is repeated until all data to be transmitted is transmitted.

FIG. 3 is a Nice Play screen diagram showing the transmission procedure when transmitting such data on the display screen 4, and 7 to 13 in the figure are displays.

Display 7 is the polling GP sent from center station 1.

Display 8 is the end of transmission EOT from the terminal device 5, display 9 is the selection of the center station 1, SEL, display 10 is the acknowledgment ACKO of the terminal device 5, fi indicator 11 is the end of text ETX from the center station 1, display 12 is the terminal The acknowledgment ACKI of the device 5 and the display 13 are numbers and alphanumeric characters representing the end of transmission EOTi of the center station 1.

To analyze the data transmission, read the information on the display screen 4,
Further, if necessary, the information can be printed out using the printer 6. At this time, the contents of displays 7 to 13 are converted into hexadecimal numbers, etc., and the number of spaces between displays 7 to 13 is counted.

[Problem that the invention seeks to solve]

Conventional data transmission analysis equipment is configured as described above, so it is necessary to know the hexadecimal code of the data transmission procedure on the communication line, and not only the basic data transmission procedure. It is necessary to be familiar with even the hexadecimal codes of these procedures, which makes it extremely difficult for people with little experience in using conventional equipment to understand them, and the display screen is also difficult to understand. There were problems such as poor visibility.

This invention was made to solve the above-mentioned problems, and it is possible to understand the data transmission procedure without knowing the hexadecimal code of the actual data transmission procedure, and to check whether the procedure is being performed normally. The object of the present invention is to provide a data transmission analysis device that can be checked by anyone on the spot, and also displays the transmission time and the data transmission procedure on the screen in an easy-to-read manner.

[Means for solving problems]

The data transmission analysis device according to the present invention is a target.

By having a standard data transmission procedure in the control equipment and selecting the same mode as the actual line, the signal code on the actual line can be compared with the standard procedure and displayed on the display screen, and the The display format is such that the center station and terminal devices are separated into the left and right sides of the display screen for easy viewing, and the transmission time is also displayed.

[For production]

The display screen display according to the present invention has an internal standard transmission procedure, so that the signal code is converted into an easy-to-understand character code.

Furthermore, by storing the time of signal code input, the time until the 91st signal code input is calculated, making it possible to analyze the data transmission procedure on the spot.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a display screen diagram, and in the figure, displays 7 to 1
3 represents the same display content as that in FIG. However, indications 7, 9, 11, and 13 are within the frame defined by indication 16, and indications 8, 10, and 13 are within the frame defined by indication 17. Displays 14, 15 and 18 are displayed between display 16 and display 17. Here, display 14 is the time from displays 7 to 13, display 15 is the time from displays 11 to 9, and display 18 is an arrow indicating the flow of the signal.

Next, the operation will be explained. Data transmitted from the center station 1 is sent to the terminal device 5 via the communication line 2 and the data transmission analysis device 3. The data transmission analysis device 3 receives such data on the communication line 2, compares it with a predetermined standard transmission procedure code, and displays it on the display screen 4 as shown in the display 7 in FIG. be done. The time from the time when the target data is received until the time when a response to this data is received from the terminal device 5 is also measured, and the result is displayed on the display screen 4 along with an arrow indicating the data transmission direction (for example, Displays 14 and 15 of 17m5°200m5) are shown. Thereafter, displays 9 to 13 are similarly processed to obtain display screens in the display format shown in FIG. 1, and are printed out to the printer 6 shown in FIG. 2 as necessary.

〔Effect of the invention〕

As described above, according to the present invention, the content of data to be transmitted according to a predetermined transmission procedure is analyzed and displayed on the display screen in a display format corresponding to the transmission procedure. 9. The situation is easy to understand. This has the effect of making it easier to determine whether transmission is normal or abnormal.
