  However, according to the above conventional technique, there are the following problems. In other words, the conventional data collection device collects data when the data structure of the transmission data transmitted by the monitored device is changed due to a change in the system configuration or addition of a function of the monitored device that is the data collection source. In order for the device to recognize the content of the recorded transmission data of the monitored device and to acquire the content, a definition for associating the data structure of the transmission data with the data content such as the data name There was a problem that the data had to be replaced.

  In addition, in order to acquire the contents of the transmission data recorded before the data structure change, it is necessary to retain the date and time when the data structure was changed and the definition data before the data structure change. There is a problem in that it is necessary to switch the definition data to be referenced depending on whether the period is before or after the data structure change date and time.

  The present invention has been made in view of the above, and even if the data structure of transmission data transmitted by the monitored device is changed due to a change in the configuration of the system or the addition of a function of the monitored device, It is an object of the present invention to provide a data collection device and a data collection method that can correctly and efficiently acquire the contents of recorded data in which transmission data is recorded.

For example, the data collection device 2 receives transmission data transmitted from one or more connected monitored devices 1 for the purpose of analyzing the cause of failure, etc., and records necessary data as recorded data over the past. Yes.

  FIG. 2 is a data flow diagram showing the flow of operation state data 11a and data structure definition data 12a transmitted by the monitored device 1 and recording data recorded by the data collection device 2. Reference numeral 11a denotes operation state data for the monitored device 1 recorded by the monitored device 1, for example, data recorded about an operation state such as normal operation or failure. The monitored device 1 transmits the operation state data 11 a to the data collection device 2 using the transmission path 3. 11b is the operation state data received by the data collection device 2, and the data content is the same as 11a. 12a is data structure definition data that defines the data structure of the operation state data 11a and 11b. The data structure definition data 12a is data that defines the structure of the operation state data, such as the data position and data name, and may be defined in the order of the operation state data (see, for example, FIG. 8). A bit position or the like may be directly defined (for example, see FIG. 9). In FIG. 8, since the operation state data is defined in the order of arrangement, it is not necessary to describe the address and bit position. As the data name, the board name, the part name, and the failure data name are described in order by separating them with “,”. Yes. In FIG. 9, since an address, a bit position, and the like are directly defined, a board name, a component name, and a failure data name are described in order by separating them with “,” as the address, bit position, and data name. The monitored device 1 transmits the data structure definition data 12 a to the data collection device 2 using the transmission path 3. 12b is data structure definition data received by the data collection device 2, and the data content is the same as 12a. Reference numeral 13 denotes reception time data acquired from the clock (not shown) of the data collection device 2 when the operation state data 11b is received, and is used as a time stamp. Reference numeral 12 c denotes data created by copying the data structure definition data 12 b inside the data collection device 2.

Reference numeral 14 denotes recording data in which the operation state data 11b, the reception time data 13, and the data structure definition data 12c are collectively recorded in one record.

  The data structure definition data 12a is transmitted from the monitored device 1 to the data collection device 1, and the timing at which the data collection device 1 receives the data structure definition data 12a is, for example, when the monitored device 1 starts operating (ie, Start-up), every fixed period, or when the data structure of the operation state data is changed. Hereinafter, a specific description will be given with reference to FIGS.

  FIG. 3 is a time chart illustrating an operation in which the data collection device 2 receives the data structure definition data 12a transmitted from the monitored device 1 at the start of the operation. As shown in FIG. 3, the monitored device 1 starts its operation by turning on the power, and then transmits the data structure definition data 12a to the data collection device 2, and the data collection device 2 receives the received data structure definition. Data 12b is stored. As a storage method, a main storage area such as a memory provided in the data collection device 2 or an auxiliary storage area such as a hard disk is used. The monitored device 1 starts to transmit the operation state data 11a after transmitting the data structure definition data 12a to the data collection device 1.

  FIG. 4 is a time chart showing an operation in which the data collection device 2 receives the data structure definition data 12a transmitted by the monitored device 1 at a constant cycle. The monitored device 1 stores the data structure definition data 12a after the operation is started, for example, at a constant cycle so that the data structure definition data 12b can be received and stored even if the data collection device 2 starts operating after the operation of the monitored device 1 starts. To the data collection device 2. After starting the operation, the data collection device 2 receives the data structure definition data 12a transmitted from the monitored device 1 and stores it as the data structure definition data 12b. Before storing the data structure definition data 12b, the operation state data 11b received from the monitored device 1 is discarded without being recorded.

  FIG. 5 is a time chart showing an operation in which the data collection device 2 receives the data structure definition data 12a after the data structure of the monitored device 1 is changed. When the structure of the operation state data 11a transmitted by the monitored device 1 is changed due to a change in the system configuration or addition of a function of the monitored device 1, the operation state data 11a is stored after the data structure change is completed. Before the transmission, the changed data structure definition data 12a is transmitted to the data collection device 2. The data structure definition data 12a of the monitored device 1 may be changed after the operation is stopped, or a new data structure definition data 12a is prepared during the operation and changed without interruption. There is also. After the operation is stopped, the flowchart for changing the data structure definition data 12a and starting the operation is the same as FIG.

  Next, the operation of the present embodiment will be described. FIG. 6 is a flowchart showing the operation of the data collection device 2 during data recording. In S1, the data collection device 2 receives the transmission data transmitted by the monitored device 1. In S2, the type of transmission data is checked. If the data structure definition data 12b, the process proceeds to S3, and if not the data structure definition data 12b, the process proceeds to S4. If the transmission data is the data structure definition data 12b, the received data structure definition data 12b is stored in S3. On the other hand, if the transmission data is not the data structure definition data 12b, it is checked in S4 whether or not the transmission data is the operation state data 11b. If the transmission data is the operation state data 11b, the process proceeds to S5 and must be the operation state data 11b. For example, the process proceeds to the flow after the process of S3. In S5, the reception time data 13 is acquired from the clock in order to store the time when the operation state data 11b is received. Subsequently, in S6, the data structure definition data 12b stored in S3 is copied to create data structure definition data 12c for recording. As described above, when the data structure definition data 12b is not stored, the received operation state data 11b is discarded without being stored, and the following operation is performed with the data structure definition data 12b stored. Continue. In S7, the reception time data 13 acquired in S5, the data structure definition data 12c copied in S6, and the received operation state data 11b are collectively recorded as one record in the recording data 14. Such an operation is sequentially executed every time transmission data is received. Note that when only the operation state data 11b and the data structure definition data 12b are assumed as transmission / reception data, the processing can be performed without providing the above S4.

  As described above, according to the present embodiment, even if the data structure of the transmission data transmitted by the monitored device is changed due to the change in the system configuration or the addition of the function of the monitored device, the data structure Since it is not necessary to hold data structure definition data that defines the structure and contents of transmission data before the change, there is no need to replace the data structure definition data. In addition, it is not necessary to manage a plurality of data structure definition data, and the data structure definition data is not mixed up. Furthermore, there is no need to store the date and time when the structure is changed, and it is possible to acquire the transmission data of the monitored device before the data structure change only by reading the recording data. Therefore, for example, it is possible to work without being aware of the system update date at the time of log data search / display processing.

  In S27, 1 is added to the recording data reading position.

  In S28, reception time data, operation state data, and data structure definition data are extracted from the recording data acquired in S26.

  In S29, the reception time data extracted in S28 is compared with the start time acquired in S23, and if reception time data ≧ start time (if the start time has passed), S30 is executed, otherwise S26 is executed.

  In S30, the reception time data extracted in S28 is compared with the end time acquired in S23, and if end time ≧ reception time data (if the end time has not passed), S31 is executed, otherwise S33 is executed.

  In S31, data having the same data name acquired in S22 is searched from the data structure definition data extracted in S28, and the data position of the data to be displayed is extracted.

  In S32, the data name acquired in S22 and the operation state data of the data position extracted in S32 are displayed. Subsequently, returning to S26, the above operation is repeated.
