DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a data display device according to the present invention will be described with reference to the drawings.
[0011]
FIG. 1 is a system configuration diagram showing a functional configuration of the present embodiment. In FIG. 1, symbol H is a data display device, M is a transmission path measuring device, and N is a communication path (for example, GP-IB or TCP / IP). The data display device H includes a data processing device 1, a display processing unit 2, a display device 3, a communication device 4, an input device 5, and a storage device 6. On the other hand, the transmission line measuring device M is composed of measurement modules M1 to M4 (external devices), a module control unit 7, a communication control unit 8, and a communication device 9, and is connected to the data display device H through the communication path N. Yes.
[0012]
The transmission line measuring apparatus M will be described first. The measurement modules M1 to M4 measure the signal transmission states of the measurement target transmission lines S1 to S4 (for example, optical fibers) assigned to the respective modules, and the module control unit 6 serves as measurement data. Output to. That is, the first measurement module M1 measures the signal transmission state of the measurement target transmission line S1, and performs module control as measurement data D1 associated with the device number 1 (that is, the measurement target transmission line S1). Output to unit 7.
[0013]
Further, the second measurement module M2 measures the signal transmission state of the measurement target transmission line S2, and performs module control as measurement data D2 relating the signal transmission state to its own device number 2 (that is, the measurement target transmission line S2). The third measurement module M3 outputs the data to the unit 7, measures the signal transmission state of the measurement target transmission line S3, and associates the signal transmission state with its own device number 3 (that is, the measurement target transmission line S3). D4 is output to the module controller 7, and the fourth measurement module M4 further measures the signal transmission state of the measurement target transmission line S4 and sets the signal transmission state to its own device number 4 (that is, the measurement target transmission line S4). Is output to the module control unit 7 as measurement data D4 associated with.
[0014]
Here, the measurement item of each of the measurement modules M1 to M4 is an abnormality of the transmission signal in each of the measurement target transmission lines S1 to S4, and more specifically, the four structural units B1, B2, and MS− constituting the transmission signal. It is the abnormality occurrence time (time after the start of measurement) and the number of abnormality occurrences in REI and HP-REI. When each measurement module M1 to M4 detects an abnormality in each of the structural units B1, B2, MS-REI, and HP-REI, the abnormality occurrence time and the number of occurrences of abnormality are output to the module control unit 7 as measurement data D1 to D4. . Although the present embodiment has four measurement modules M1 to M4 as described above, the number of measurement modules is not limited to four and may be larger.
[0015]
The module control unit 7 controls the measurement operations of the measurement modules M1 to M4, and outputs the measurement data D1 to D4 input from the measurement modules M1 to M4 to the communication control unit 8. The communication control unit 8 controls transmission of the measurement data D1 to D4 by the communication device 9. The communication device 9 transmits the measurement data D1 to D4 to the communication device 4 under the control of the communication control unit 8.
[0016]
On the other hand, the data processing device 1 in the data display device H is an arithmetic device that operates based on a data processing program stored in the storage device 6 in advance, and controls the overall operation of the data display device H. Further, the data processing apparatus 1 processes information such as the measurement data D1 to D4 based on the data processing program, thereby displaying an initial screen for displaying the outline state of the measurement target transmission lines S1 to S4 in a graph. Display data and secondary screen display data for displaying a graph of the detailed states of the measurement target transmission lines S1 to S4 are generated and output to the display processing unit 2. Details of the processing operation of the data processing apparatus 1 will be described later.
[0017]
The display processing unit 2 converts the initial screen display data or the secondary screen display data into image data and outputs the image data to the display device 3. The display device 3 displays an initial screen or a secondary screen based on the image data. The communication device 4 communicates with the communication device 9 of the transmission path measuring device M, receives each measurement data D1 to D4 from the communication device 9, and outputs it to the data processing device 1.
[0018]
The input device 5 is used to input designation information on the initial screen or secondary screen and instruction information regarding each operation of the transmission path measuring device M to the data processing device 1, and is, for example, a keyboard or a mouse. The storage device 6 stores the data processing program and classifies the measurement data D1 to D4 for each measurement module M1 to M4, that is, for each device number 1 to 4, and sequentially stores and stores the data.
[0019]
Next, the operation of the present embodiment configured as described above will be described in detail along the flowchart shown in FIG. This flowchart shows the processing procedure of the data processing apparatus 1 based on the data processing program.
[0020]
First, when a measurement start instruction is input to the input device 5, the data processing apparatus 1 transmits this measurement start instruction to the transmission path measurement apparatus M via the communication apparatus 4 and the communication path N. When the communication device 9 receives the measurement start instruction, the communication control unit 8 of the transmission line measuring apparatus M transfers the measurement start instruction to the module control unit 7. When the measurement start instruction is input in this way, the module control 7 outputs a measurement start instruction to each of the measurement modules M1 to M4. As a result, each of the measurement modules M1 to M4 receives each measurement target transmission line S1. ~ Measurement of signal transmission state of S4 is started. Note that the measurement interval of the signal transmission state in each of the measurement modules M1 to M4 is, for example, about 1 second.
[0021]
That is, when a measurement start instruction is input to each of the measurement modules M1 to M4, the abnormality occurrence time in each of the structural units B1, B2, MS-REI, and HP-REI of the transmission signal for each of the measurement target transmission lines S1 to S4 Start measuring the number of abnormal occurrences.
[0022]
On the other hand, the data processing device 1 sequentially acquires the measurement data D1 to D4 of the measurement modules M1 to M4 from the transmission line measurement device M via the communication device 4 at predetermined time intervals (step S1), and the storage device 6 Then, the measurement modules M1 to M4 are classified and sequentially stored and accumulated (step S2). That is, the storage device 6 stores a plurality of pieces of measurement data D1 to D4 acquired by the measurement modules M1 to M4 as time elapses from the start of measurement.
[0023]
Further, the data processing apparatus 1 monitors whether or not each measurement data D1 to D4 indicates an abnormality in each measurement target transmission line S1 to S4 (step S3). When the occurrence of an abnormality is detected (in the case of Yes), an error flag is set in the structural unit B1, B2, MS-REI, HP-REI in which the abnormality has occurred in the measurement module in which the abnormality has occurred (for example, the measurement module M1). In step S4, all the measurement data D1 to D4 are read from the storage device 6 (step S5). On the other hand, if no abnormality has occurred (in the case of No), all the measurement data is directly read from the storage device 6. (Step S5).
[0024]
When the data processing device 1 reads all the measurement data D1 to D4 from the storage device 6 in this manner, the data processing device 1 generates display data for initial screen and display data for secondary screen based on this (step S6), and the former. The initial screen display data is output to the display processing unit 2 (step S7). As a result, the display processing unit 2 converts the initial screen display data into image data and outputs the image data to the display device 3, and the initial screen G1 shown in FIG.
[0025]
The initial screen G1 displays a graph a1 with the horizontal axis representing the time after the start of measurement and the vertical axis representing an error in each of the measurement modules M1 to M4. The operation buttons b1 to b4 for instructing the display of the secondary screen are displayed every .about.4. The graph a1 shows, as an example, the measurement target transmission line S3 that is the measurement target of the device number 3 (measurement module M3) 30 seconds after the start of measurement in the measurement target transmission line S1 that is the measurement target of the device number 1 (measurement module M1). This indicates that some abnormality occurred 50 seconds after the start of measurement and 20 seconds after the start of measurement in the measurement target transmission line S4 which is the measurement target of the device number 4 (measurement module M4).
[0026]
For example, when the operation button b1 is operated on the initial screen G1 (step S8), the data processing apparatus 1 outputs the secondary screen display data to the display processing unit 2 (step S9), and displays it. The device 3 displays a secondary screen G2 (see FIG. 4) instead of the initial screen G1. Note that a display instruction for the secondary screen G2 instead of the initial screen G1 can also be input to the data processing device 1 from the input device 5.
[0027]
As shown in FIG. 4, the secondary screen G2 shows details on the abnormality of the measurement target transmission line S1, that is, any of the constituent units B1, B2, MS-REI, HP-REI of the transmission signal of the measurement target transmission line S1. A graph c1 indicating at which point an abnormality has occurred and operation buttons d1 to d4 for instructing display of the number of occurrences of abnormality for each of the structural units B1, B2, MS-REI, and HP-REI are displayed. This figure shows that an abnormality occurred 30 seconds after the start of measurement for the structural unit B2 of the measurement target transmission line S1. When the operation button d2 of the structural unit B2 in which an abnormality has occurred on the secondary screen G2 is operated, a graph c2 indicating the number of occurrences of the abnormality of the structural unit B2 is expanded and displayed on the secondary screen downward.
[0028]
When the initial screen G1 and the secondary screen G2 are displayed as described above, the outline and details of the abnormal states of the measurement target transmission lines S1 to S4 are grasped, and when a measurement end instruction is input from the input device 5 (step S10), The data processing apparatus 1 completes all the processes, and when a measurement continuation instruction is input (step S10), the process returns to step S1 and repeats each process described above.
[0029]
According to the present embodiment, an overview regarding the abnormal state of each of the measurement target transmission lines S1 to S4 is grasped by the initial screen G1, and each measurement target transmission line S1 to S2 is displayed by the secondary screen G2 displayed instead of the initial screen G1. Details regarding the abnormal state of S4 can be grasped. Further, since the secondary screen G2 is displayed instead of the initial screen G1, a limited display area on the display device 3 can be used efficiently.
[0030]
FIG. 5 shows the entire display area of the display device 3. The display device 3 displays not only the initial screen G1 and the secondary screen G2 based on the measurement data D1 to D4 described above, but also setting screens G3 to G5 indicating various setting information such as measurement conditions. A lot of information is displayed in addition to the data D1 to D4. In such a display device 3, the measurement data D1 to D4 are displayed as the initial screen G1 and the secondary screen G2, thereby suppressing the display area relating to the measurement data D1 to D4 and the measurement target transmission lines S1 to S4. Can be displayed in an extremely easy-to-understand manner.
[0031]
【The invention's effect】
As described above, according to the present invention, an outline of data related to each external device is displayed as a graph on the initial screen, and when a specific external device is designated, details of the data related to the specific external device are displayed on the initial screen. Instead, since the graph is displayed as a secondary screen, data acquired from all external devices can be efficiently displayed in a limited display area, and the outline and details of the data can be easily grasped.
