Description

  The present invention relates to an engineering device that creates an operation file for operating a control device.

  As a monitoring system that monitors and controls multiple field control devices in a building, different manufacturers such as air conditioning equipment, lighting equipment, electrical equipment, disaster prevention equipment, etc. using an open network such as BACnet (Building Automation and Control networking protocol) Multi-vendor compatible systems that connect these systems and perform monitoring and control have become widespread.

  When constructing a monitoring system corresponding to this BACnet, the engineering apparatus creates a JOB file that records management information such as device information, management point information, and object information managed by the monitoring apparatus in accordance with the BACnet standard. Creating. Further, the engineering device creates an operation file (download file) for operating the host controller managed by the monitoring device based on the created JOB file, and downloads it to the corresponding host controller.

  On the other hand, in order to increase the efficiency of trouble analysis, the host controller has been equipped with a function of checking at startup whether there is a problem with the download file created by the engineering device. As a result, if it is determined that there is an error in the data of the download file and consistency is not achieved, (1) the host controller does not shift online normally, (2) an error occurs even if it shifts online. However, it does not operate normally, and in the worst case, (3) the on-site trouble of repeated restarts has occurred.

Therefore, in order to solve the problems (1) to (3), the engineering device (engineering tool) supports the file creation / consistency check function. As a result, it is possible to avoid the problems (1) to (3) described above by correcting the file so as to maintain consistency with respect to the expected data abnormality.
However, for some reason (data transmission / reception between the host controller and the monitoring device, etc.), the download file may be in a data abnormal state exceeding the assumption of the file creation / consistency check function of the engineering device. In this case, the user cannot avoid the abnormal data state of the download file. Furthermore, depending on the situation, it may be necessary to modify the file beyond the specification range of the engineering device.
When such a data abnormality occurs, an engineer detects abnormal data from an enormous file and manually changes it.

  On the other hand, there is a program maintenance device provided with a difference detection mechanism for detecting whether or not a predetermined constant value matches an execution value (see, for example, Patent Document 1). This program maintenance device is configured to rewrite and modify a constant value to an execution value by a constant value rewriting mechanism when the difference detection mechanism determines that the constant value and the execution value do not match. .

JP-A-8-328842

  In the conventional monitoring system, when a download file data abnormality that exceeds the assumption of the file creation / consistency check function of the engineering device occurs, the engineering device cannot correct the file. For this reason, the engineer manually performs correction work, and there is a problem that it takes time to correct the download file.

  Further, in the method disclosed in Patent Document 1, it is assumed that the constant value is correct. However, when applying to a monitoring system, it is necessary to always hold an accurate master file to be compared. . However, in the monitoring system, data is changed irregularly, such as addition or change of management targets, and the file save after the change is handled manually by the engineer. Therefore, it cannot be said that the master file is always accurate, and there is a problem that it is difficult to apply the method disclosed in Patent Document 1 to a monitoring system.

  The present invention has been made to solve the above-described problems. When a data abnormality that exceeds the assumption of the file creation and consistency check function of the engineering device occurs in the download file, the data abnormality is corrected. An object of the present invention is to provide an engineering device capable of reducing time.

  The engineering apparatus according to the present invention includes a file upload unit for uploading an operation file from a control device, an upload file holding unit for holding an operation file uploaded by the file upload unit, and an operation file held in the upload file holding unit A normal file holding means for holding a normal operation file having the same configuration as the above, file information indicating the operation file to be integrated held in the normal file holding means, and an area for reading data from the operation file to be integrated From the area designating unit that accepts the input of the area information indicating the file information received from the normal file holding unit, the data corresponding to the area information of the action file corresponding to the file information accepted by the area designating unit is read, and the upload file Le holding means reads data that does not correspond to the region information of the operation file corresponding to the file information is obtained by a file integration means for performing file integration.

  According to this invention, since it is configured as described above, when a data abnormality exceeding the assumption of the file creation / consistency check function of the engineering device occurs in the download file, the correction time of the data abnormality is shortened. Can be planned.

Further, the engineering device 1 generates an operation file (download file) for operating each upper controller 4 based on the created JOB file, and downloads it to the corresponding upper controller 4.

In addition, when the download file held by the host controller 3 is modified such as addition / change / deletion due to specification change / function addition after system operation, the engineering device 1 is stored in each host controller 4 The downloaded download file is uploaded, and this download file is corrected as master data.
Furthermore, when an unexpected data abnormality occurs in the download file for some reason, the engineering device 1 integrates (merges) the download file with a normal operation file having the same configuration, thereby normalizing the download file. Return to the state. The configuration related to the file integration function of the engineering device 1 will be described later.

The monitoring device 2 monitors and controls a plurality of host controllers 4 connected via the BACnet. The monitoring / control information by the monitoring device 2 is displayed on the display device 3.
The host controller 4 monitors and controls a plurality of lower controllers 5 connected via the lower network according to the control by the monitoring device 2. The host controller 4 operates based on a download file from the engineering device 1.
The lower controller 5 controls a plurality of field control devices (not shown) connected via the lower network according to the control by the upper controller 4.

Next, a configuration related to the file integration function of the engineering apparatus 1 will be described. FIG. 2 is a diagram showing a configuration relating to the file integration function of the engineering apparatus 1 according to the first embodiment of the present invention.
As shown in FIG. 2, the engineering apparatus 1 includes a file upload unit 11, an upload file holding unit 12, a normal file holding unit 13, a region specifying unit 14, a file integration unit 15, and a file download unit 16.

The file upload unit 11 uploads a download file from the host controller 4.
The upload file holding unit 12 holds the download file uploaded by the file upload unit 11.

  The normal file holding unit 13 holds a normal operation file (normal file) having the same configuration as the download file held in the upload file holding unit 13. As the normal file, an operation file newly created by the engineering apparatus 1, a normal operation file uploaded from the host controller 4 in the past, an operation file previously integrated by the file integration means 15 or the like is used.

  In response to a request from the file integration unit 15, the area designating unit 14 includes file information indicating the operation file to be integrated held in the normal file holding unit 13 and an area for reading data from the operation file to be integrated. The input with the area information to be shown is received from the user. Here, the user inputs a file number indicating an operation file to be integrated as file information. Further, a record number indicating a region of a series of data (name, unit, etc.) is input as region information. Further, as the area information, a field number indicating an area of individual data in each record may be input.

Based on the file information and the region information received by the region specifying unit 14, the file integration unit 15 retains a download file (abnormal file) having an unexpected data abnormality held in the upload file holding unit 12 and a normal file. The file is integrated with the normal file held in the means 13, and the abnormal file is returned to the normal state. Here, the file integration unit 15 reads data corresponding to the region information from the normal file corresponding to the file information, reads data not corresponding to the region information from the abnormal file corresponding to the file information, and reads both the read data. Integrate.
The file download unit 16 downloads the operation file that has been subjected to file integration by the file integration unit 15 to the corresponding host controller 4.

  Here, the unexpected data abnormality of the download file means that the operation expected by the engineering apparatus 1 is not performed. For example, in the BIENet of the IEIEJ-G-0006: 2006 standard, the initial value of Alarm Value needs to be set to 1, but if it is set to 0 for some reason, the host controller 4 is operating normally. It will not work. However, since this Alarm Value is a field that is not subject to correction, the initial value cannot be corrected from 1 to 0.

Therefore, as shown in FIG. 3, a normal operation file having the same configuration is used for a download file having an unexpected data abnormality, and integration is performed in field units, record units, and file units. For example, based on the uploaded download file (Alarm Value is in an abnormal state), the newly created Alarm Value of a normal operation file is integrated on a field basis. Thereby, abnormal data can be converted into normal data, and all files can be converted into normal download files.
Hereinafter, the operation of the engineering apparatus 1 when an unexpected data abnormality occurs in the download file as described above will be described.

Are integrated (step ST43). That is, as shown in FIG. 5, the file integration unit 15 reads out data (underlined portion) corresponding to the region information from the normal file corresponding to the file information and does not correspond to the region information from the abnormal file corresponding to the file information. Data (underlined part) is read out, and both the read out data are integrated.
In the abnormal file shown in FIG. 5, the underlined area (the second field, fourth field (column) of the first record (row), the third field of the third record, the fourth field, fifth field of the fifth record) The first and fifth fields of the sixth record) indicate that the data is in an abnormal state.

  Next, the file download unit 16 downloads the operation file (integrated file) subjected to file integration by the file integration unit 15 to the corresponding host controller 4 (step ST44).

  As described above, according to the first embodiment, when an unexpected data abnormality occurs in a download file, this download is performed using an editor that supports a file integration function that exceeds the specification range of the engineering device 1. Since the file is integrated with the normal operation file of the same configuration, the download file can be returned to the normal state at an early stage, trouble can be quickly avoided on site, and engine efficiency can be improved. Improvements can be made.
