Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote supervisory control system used for supervisory control of a plant or the like.

[0002]

2. Description of the Related Art Conventionally, a centralized supervisory control system has been adopted for supervisory control of a plant. In this system, as shown in FIG. 6, the centralized supervisory control device 1 is directly connected to the signal lines 2a to 2d.
Alternatively, a signal input device 4, a signal output device 5, a data display device 6, and a data input / output device 7, which are field devices arranged at the plant site, are connected via a LAN (Local Area Network) 3.

As shown in FIG. 7, the centralized supervisory control device 1 includes a database 9, a data input device 10, a data display device 11, a signal input / output device 12, an LA, and an arithmetic control device 8.
N controller 13 and the like are connected.

The arithmetic and control unit 8 transmits and receives to and from the on-site equipments 4 to 7 at the plant site via the LAN control unit 13 and the LAN 3, and receives information on the operation and operation of the system from the database 9. Then, the control and monitoring information obtained by processing the input data such as the monitoring information at the plant site is displayed on the data display device 11 to provide the operator with an appropriate operating environment.

In addition, LA is used to connect the center and the site.
A remote monitoring and control system using a telephone line without using N has been considered. As shown in FIG. 8, the centralized monitoring control device 1 is provided with a communication control device 14, and the communication control device 14 and field devices 4 to 7 are connected via a telephone line 15. In addition, the system shown in the figure has some of the functions of the centralized monitoring control device 1 on site by installing the remote monitoring control device 16 on site.

Further, as shown in FIG. 9, the center and the site are connected via a LAN 3, and a remote monitoring control device 17 is provided on the site.
There is a remote monitoring and control system in which various data input / output devices are connected. In such a system, a part of the monitoring control can be performed by the remote monitoring control device 17 even in the field.

The above-mentioned remote monitoring control system is a LAN
The centralized monitoring control device 1 collects the monitoring data from each site connected by the telephone 3 and the telephone line 15. Then, the data is processed there, and the central data display device 11
The data related to supervisory control is displayed on. Further, in the case of the configuration shown in FIG. 9, some monitoring control data could be known even in the field only in the place where the remote monitoring control device 17 is installed.

However, as described above, the place where the supervisory control information of each site can be obtained is limited to the place where the centralized supervisory controller 1 or the remote supervisory controller 17 is installed. There was an inconvenience that such data could not be known in the place where the operation terminal of the field equipment was located.

When a new field device is added or reduced, it is necessary to change the data relating to the system configuration stored in the database 9 of the centralized supervisory control apparatus 1. In such a case, in addition to a worker who replaces the equipment on site, a person who rewrites the information at the same time at the center is required due to the system configuration change.

In the conventional remote monitoring control system, in order to improve reliability, the monitoring control system and the database are duplicated as shown in FIG. 10, and one of them constitutes a standby system. However, since the duplicated database was centrally managed by the data storage device in the central area, if the data storage device goes down, there is a possibility that the entire system will stop. Information is lost and proper operation cannot be performed.

[0011]

As described above, the conventional remote monitoring and control system cannot freely obtain the driving information at any operation place, and when the data storage device storing the database goes down. When the control and monitoring information is lost and the system configuration is changed, there is a problem that the configuration information of the database cannot be changed unless the central side rewrites it.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a remote monitoring control system capable of providing an appropriate information environment regarding monitoring control information.

[0013]

In order to achieve the above object, the present invention collects on-site monitoring information by means of a central monitoring and control device main body having a database relating to monitoring and control of an object to be monitored, and collects the collected information as described above. In a remote monitoring control system for collectively monitoring and controlling the site with monitoring control information obtained by processing based on a database, the monitoring control information is received by wireless communication with the main body of the central monitoring control device, and the received information is received. A means for displaying, a means for wirelessly communicating with the main body of the central supervisory control device to change the system configuration information stored in the database, a wireless communication with the main body of the central supervisory control device for copying the database A wireless portable device equipped with at least one means for forming a database is configured to be deployed on site. .

[0014]

Since the present invention has taken the above means, the wireless portable device displays the centralized supervisory control information by wireless communication between the wireless portable device and the central supervisory controller main body. Alternatively, the system configuration information is rewritten from the wireless mobile device installed at the site to the central monitoring control device body. In addition, the central database is copied to the wireless handheld device and stored as a distributed database.
