Description

  The present invention relates to a software management system that manages changes in data held as master data.

  Conventionally, in a plant monitoring device or the like, a plant is monitored based on data held as master data. In this case, the software for monitoring has been created by the manufacturer, and the media management of the software has been performed by the manufacturer. However, recently, with the spread of personal computers, the user's knowledge about computers has also improved, and there is an increasing demand for users to change the monitoring device software themselves. In response to such a request, the user has been allowed to change the software.

  In this case, the problem is the management of the final software. When the user changes the software, there is no problem when the user manages the subsequent software, but there are cases where the manufacturer is requested to change the software. In that case, if the user's change management is not sufficiently performed, the manufacturer may not know the user's change contents and the final media, so if the manufacturer modifies the software, the user's change contents may be lost. is there.

  In other words, conventionally, the change function 25 reads the source file 35 as shown in FIG. In this method, if the final version of the source file 35 is not properly managed, the master data 34 is destroyed. If the number of people who change the source file 35 is one place, the management by the human system will work to some extent, but if there are multiple people who change the source file 35, such as users and manufacturers, there are limits to the management of the human system. The master data 34 may be destroyed.

  In this way, in a plant monitoring device used by a user, if the software of the monitoring device, such as a user and a manufacturer, is changed at a plurality of locations, the changed software will be lost if the final media cannot be managed. There is a fear.

  An object of the present invention is to provide a software management system capable of changing software without losing data before change by saving the data before change and the contents of change when performing software change in a monitoring device or the like. is there.

  A software management system according to the present invention is a software management system for managing a change in data held as master data, and includes a pre-change data storage unit capable of storing change data for the master data for a plurality of changes. A change data storage means for storing change data for the master data every time it is changed; and upon receiving a change content for the master data, the change data at the previous change stored in the change data storage means is changed. Change content accepting means for saving the change data accepted this time in the change data saving means while saving in the previous data saving means, current change data saved in the change data saving means, and the pre-change data saving means Read the data before change stored in the The comparison contents can be visually displayed, and the change difference comparison means for extracting only the changed part as change difference data, and the change difference data storage for saving the change difference data extracted by the change contents comparison means And difference data combining means for reading the change difference data from the change difference data storage means and combining the read difference data with the master data.

  According to the present invention, change data for a plurality of past times is stored, the past data is compared with the current change data, the changed part is confirmed, and only the changed part is reflected in the master data. Even if management is not done correctly, software changes can be implemented without destroying the current master data.

  Hereinafter, an embodiment of a software management system according to the present invention will be described in detail with reference to the drawings.

  First, the main points of the present invention will be described. In the present invention, a plant monitoring device or the like has a function of storing pre-change data and change contents, respectively, so as to grasp the difference from the current change contents. And only the difference is reflected in the master data, so that the loss of the data before the change can be prevented. According to the present invention, the software change in the monitoring device or the like can be executed in a plurality of places such as the user and the manufacturer without erasing the past software change data. This will be described in detail below.

  FIG. 2 shows a system configuration example of a general plant monitoring apparatus. This type of monitoring device is usually composed of a CRT monitoring device 11, a control controller 13, and a control LAN 12. With this system configuration, it is possible to monitor the state of various types of monitoring target equipment and perform operations and the like.

  FIG. 1 is a functional block diagram showing the configuration of this embodiment. Normally, in this type of monitoring apparatus, the monitoring target facility is monitored by the monitoring function 24 with reference to the master data 34 defining the information to be monitored. When the monitoring contents change, the master data 34 needs to be changed.

  In FIG. 1, reference numeral 31 denotes pre-change data storage means, which is configured to store change data for the master data 34 for a plurality of changes. Reference numeral 32 denotes change data storage means, which stores change data for the master data 34 every time it is changed. Reference numeral 21 denotes a change content accepting unit. When a change content for the master data 34 is accepted, the change data at the previous change stored in the change data storage unit 32 is stored in the pre-change data storage unit 31. The change content accepting unit 21 stores the change content accepted this time in the change data saving unit 32.

  Reference numeral 22 denotes a change content comparison unit, which reads the current change data stored in the change data storage unit 32 and a plurality of pre-change data stored in the pre-change data storage unit 31 and compares them. Can be displayed visually. Further, the change content comparison unit 22 takes out only the part changed this time as change difference data and stores it in the change difference data storage unit 33. Reference numeral 23 denotes difference data combining means for reading the change difference data stored in the change difference data storing means 33 and combining it with the master data 34.

  In the above configuration, when a change occurs, the change content receiving means 21 receives the change content. When the change content accepting unit 21 accepts the change content, the change data accepting unit 21 causes the pre-change data storing unit 31 to store the change data at the previous change stored in the change data storing unit 32. The pre-change data storage unit 31 stores the number of changes and data for a plurality of times.

  When the previous change data is copied to the pre-change data storage unit 31 in this way, the change content reception unit 21 causes the change data storage unit 32 to store the current change content.

  Next, the change content comparison unit 22 compares the current change data stored in the change data storage unit 32 with a plurality of pre-change data stored in the pre-change data storage unit 31.

  These contents are displayed visually. With this display function, it is possible to confirm whether the changed data has not broken the part other than the changed data. In addition, when the changed data has broken the part other than the changed data, the broken data is read from a plurality of past data read from the pre-change data storage unit 31 and restored.

  The change content comparison unit 22 extracts only the changed portion from the change data that has become normal by the above processing, and stores it in the change difference data storage unit 33 as change difference data.

  Next, the difference data combining unit 23 reads the change difference data stored in the change difference data storage unit 33 and combines this data with the master data 34. Thereby, since only the master data of the changed part is changed, the master data not to be changed is not destroyed.

  In this way, change data for the past multiple times is saved, the past data is compared with the current change data, the changed part is confirmed, and only the changed part is reflected in the master data, so the management of the final media is possible. Even if it is not correct, the software can be changed without destroying the current master data.

It is a block diagram which shows one Embodiment of the software management system by this invention. It is a figure which shows the system configuration example of a general plant monitoring apparatus. It is a figure which shows the example of a conventional system.
