Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a central monitoring and control system in a monitoring and control system for monitoring the operation status of various facilities such as electricity and air conditioning in a building facility, and operating and controlling each facility. And a local monitoring and control device.

[0002]

2. Description of the Related Art In a building monitoring and control system used for monitoring and controlling a large-scale facility such as a building, a CRT screen installed in a monitoring room or the like scatters the facility.
By centrally monitoring and operating the operation states of various facilities such as electricity and air conditioning, the efficiency of building facility management is enhanced.

In such a building management control system, since it is required to constantly monitor and control the equipment, the reliability (availability) that allows the system to be operated continuously.
Is an important system evaluation criterion. Further, even when the system is stopped due to a failure of the storage device, it is important to quickly restore the system to a state close to the state before the failure (maintenance).

[0004]

Among these items, in terms of availability, measures for improving reliability, such as using durable components and duplicating equipment, have been adopted. Have been.

On the other hand, in terms of maintainability, a maker provides a service for promptly replacing or repairing a failed device, and a backup copy of software data stored in the device is stored in another storage medium in advance. In many cases, they are created and used in the event of a failure to perform recovery.

However, the software data stored in the apparatus can be roughly classified into two types of software: those that hardly change or change after the start of system operation, such as operating systems and application programs; During operation,
Some are rewritten.

[0007] In the conventional building monitoring and control system, the above-mentioned data backup method is often performed only at the time of maintenance and inspection of the system, so that the frequency of backup update is extremely low. For this reason, even if software data is restored using a backed-up medium in the event of a system failure, some data, such as device operation history and form data, that has been sequentially rewritten during operation, In fact, there were many things that could not be recovered.

Further, in a building monitoring and control system in which storage devices are duplicated so that even if one of the storage devices fails, the other storage device is used for continuous operation, the cost of the device increases. There was a problem that it would.

In view of the above circumstances, according to the present invention, a data backup operation for a building at a remote location is performed from a central monitoring room according to a preset schedule or an instruction from an operator, and a failure occurs. It is an object of the present invention to provide a central monitoring and control device in a monitoring and control system capable of dramatically improving not only the maintainability at the time but also the efficiency of daily tasks on the user side.

According to the second aspect of the present invention, data stored in a local storage device or the like of each building at a remote location is automatically transmitted to a central monitoring room or the like to be backed up, and the equipment of each building or the like goes down. In the case of a monitoring and control system, the data backed up in the central monitoring room can be used to restore the data of the downed device, which can dramatically improve the maintainability of the system. It is intended to provide a local monitoring and control device.

[0011]

According to the present invention, there is provided a monitoring and control system for monitoring and controlling each facility while communicating with a local monitoring and control device. The central monitoring and control device, based on a preset schedule or as needed, based on an input instruction, among the data stored in the local storage unit of the local monitoring and control device, data to be backed up. It is characterized by comprising a backup data fetching unit to be fetched, and a remote storage unit for storing data fetched by the backup data fetching unit.

According to a second aspect of the present invention, there is provided a local supervisory control device applied to the supervisory control system according to the first aspect,
When the restoration process is started, a backup target data restoring unit that fetches data stored in the remote storage unit of the central monitoring and control device and restores the data in the local storage unit is provided.

According to the above-mentioned configuration, in the first aspect, the data stored in the local storage unit of the local monitoring and control device by the backup data acquisition unit based on a preset schedule or as occasion demands the input instruction. Of the data to be backed up, the data to be backed up is stored and stored in the remote storage unit, so that the data can be backed up from the central monitoring room to the remote buildings, etc., according to a preset schedule or instructions from the operator. By performing the work, not only the maintainability at the time of occurrence of a failure but also the efficiency of daily work on the user side is dramatically improved.

According to a second aspect of the present invention, when the restoration process is started, the data stored in the remote storage unit of the central monitoring and control device is fetched by the backup target data restoration unit and restored in the local storage unit. By automatically transmitting data stored in local storage units of buildings and the like in remote locations to the central monitoring room, etc., and backing them up, when the equipment in each building goes down, the central monitoring room Using the data backed up on the side, the data of the downed device is restored, and the maintainability of the system is dramatically improved.

As described above, according to the present invention, the central monitoring and control device according to the first aspect of the present invention provides a remote control system for each building or the like from the central monitoring room according to a preset schedule or an instruction from an operator. By performing a data backup operation, not only the maintainability in the event of a failure, but also the efficiency of daily tasks on the user side can be dramatically improved.

According to the second aspect of the present invention, the data stored in the local storage device of each building or the like in a remote place is automatically transmitted to the central monitoring room or the like, and is backed up. When one of the units goes down, the data backed up in the central monitoring room can be used to restore the data from the down unit, thereby greatly improving the maintainability of the system. it can.
