| description | PROBLEM TO BE SOLVED: To prevent a facility database from being erroneously updated or changed in the middle of its maintenance or test. SOLUTION: Concerning the distributed monitor and control system such as a power system monitor and control system composed of plural distributed computers, this system is provided with at least two main computers A1. and B2 equipped with facility databases 104 and 204 for online respectively storing facility data, computer D4 for maintenance for maintaining these main computers and facility data base 8 for maintenance. Further, this system is provided with a facility database 304 for online and a test computer C3 for testing the facility database for maintenance and additionally, a facility data state table 5 is commonly provided for holding the states of the facility database for online and the facility data base for maintenance at the respective computers. In the case of maintenance, whether switching is enabled or not is judged from the states of databases and an interlock function is provided for preventing erroneous changes. |
