2. Description of the Related Art A distribution system monitoring control device generally refers to a control device that monitors and controls switches and the like installed in various places of a distribution line. Here, the connection of the distribution system and the attributes of each switch are managed. The set of files that are created is called a database. Since new switches and system changes are made every day, it is necessary to update the database in the distribution system monitoring and control unit to match the system at the site.

Since the database is important for monitoring and controlling the power distribution system and is a huge amount, if the database is destroyed due to equipment failure or the like, it takes several months for the repair work, During that time, monitoring and control are disabled, which causes a great obstacle to stable power supply. In order to deal with this, in the conventional distribution system monitoring and control device, a backup method has been adopted, in which the operator regularly saves the database using a medium such as a magnetic tape or duplicates the disk device.

As described above, the method of storing the database using the medium and duplicating the disk is to manage the database at the same point where the distribution system monitoring and control device is installed. In the event of a fire or earthquake, the database may be lost.

In addition, the method of periodically storing the database using a medium depends on the operator, which is a burden on the operator. Therefore, it was a challenge to not lose the database even if a fire or an earthquake occurs and to provide a database backup method without burdening the operator.

In order to solve the above-mentioned problems, the present invention connects a point where a distribution system monitoring and control device is installed and another device in a remote place which is hard to be damaged by a fire or an earthquake, by a transmission line. By backing up the database of its own device on another device and automatically backing it up periodically, the purpose is to prevent the loss of the database and to provide a system that does not depend on the operator.

[0104]

As described above, according to the present invention,
Even if an earthquake or fire occurs and the database needs to be restored, it can be received from other devices because the distribution system monitoring and control device database can be sent to another distribution system monitoring and control device for backup. You can deal with it immediately. Also, because you can select from multiple defined distribution system monitoring and control devices that are transmission destinations, you can increase the backup destination and increase the probability of not being damaged by the earthquake,
It leads to improvement of reliability.

Further, the transmission destination can be changed when another distribution system monitoring control device is newly installed, and the combination of transmission destinations of other distribution system monitoring control devices can be considered. In addition, by having a means for identifying and storing two or more databases other than the power distribution system monitoring and control device, it becomes possible to back up as many databases as the free space of the disk allows, and to back up the backed up databases. You can also concentrate and remember.

Further, the database can be automatically backed up in a fixed cycle, and the operator does not need to be aware of the database backup time, and a system with less burden on the operator can be provided. Further, since the data transmission can be started at the time when the operator makes a request, it is possible to provide a system capable of coping with the case where the transmission is urgent.

Furthermore, during system fault processing or system control, C
Since the start of transmission is delayed when the PU load is high, a problem such as a delayed response due to database backup does not occur. In addition, since data is exchanged with compressed data when transmitting / receiving the database, the transmission can be performed at high speed and at low cost. Further, by storing the database of another distribution system monitoring and control device in a compressed state, the disk area can be saved.

By storing the last update date and time of the database, it is possible to judge whether or not the transmission is necessary and unnecessary transmission is omitted. Therefore, it is possible to reduce the load. The effect is obtained.
