Abstract

PURPOSE:To change the set without increasing the burden on a manager by changing the measuring data of an equipment in a low or fast update period and outputting it to a central monitoring and controlling system so as to maintain the traffic quantity of transmission at a proper level. CONSTITUTION:When pattern data is displayed on the CRT device 4 of the central monitoring and controlling system 1, patterns No. data added to the piece of pattern data is outputted to a slave station device 11 through a transmission line 8 and a transmission processor 10. Registered measuring data is changed into the fast update period corresponding to pattern No. data taken in the slave station device 11. Consequently, the slave station device 11 outputs measuring data corresponding to pattern No. data in the fast period and that which does not corresponding to pattern No data in the low update period. Fast update period data is used as data of a display picture on the CRT device 4.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a central supervisory control system for supervising and controlling various equipments installed in buildings and plants.

[0002]

2. Description of the Related Art Modern factories and facilities such as plants have many equipment such as high-voltage substations, disaster prevention equipment, and air conditioners, and these equipment operate in cooperation with each other. This is necessary to achieve the operation according to the design specifications. Therefore, it is desirable that the operating condition of all equipment is monitored at a specific place and controlled from this specific place. Normally, these monitoring and control are
It is designed to be performed by a central supervisory control system.

The above-mentioned central supervisory control system is provided with equipment devices classified by use, location, etc., and slave station devices connected in equipment device group units so as to monitor and control the classified equipment devices. And LAN (Lo
central monitoring and control device connected via a cal area network), and the central monitoring and control device uses the CRT device for measuring data and failure status data of the equipment input from the slave station device and remote controller. The operating status of all equipment is made known to the administrator by displaying the image on the screen or by printing out on a printer.

By the way, in the conventional central supervisory control system, the measurement data of the equipment is inputted to the central supervisory controller with an update cycle set to, for example, 30 seconds or 1 minute. When the update cycle is shorter than this update cycle (for example, 1 second), the update cycle of all equipment is uniformly changed to 1 second, or
A request signal is output from the central monitoring and control device every one second for equipment having a short update cycle.

[0005]

However, when the update cycle of all the equipment is uniformly changed, even the measurement data that does not need to be shortened is output from the equipment, so that the slave station device The load on the transmitter and the receiver of the central monitoring and control apparatus increases, and the traffic volume on the transmission path such as the LAN easily becomes excessive. Therefore, in a central supervisory control system that makes such a setting change, urgent information data such as failure status data is not immediately taken into the central supervisory control device.
There is a problem of insufficient monitoring of equipment. Further, in a central supervisory control system that outputs a request signal from the central supervisory control device for each update cycle to perform supervisory control, the operation of outputting the request signal causes an increase in the burden on the central supervisory control device, so that As in the case of uniformly changing the update cycle of the equipment, there is a problem that the equipment equipment is insufficiently monitored.

Therefore, by providing the slave station device with a low-speed update cycle and a high-speed update cycle in a selectable manner, the central supervisory control device specifies equipment equipment requiring a high-speed update cycle to the slave station device. A central supervisory control system is conceivable, in which only the measurement data of desired equipment is set and changed in a high-speed update cycle to perform supervisory control. However, in this case, it is necessary to select the equipment and specify it as the slave station device, which increases the burden on the administrator. Further, since communication processing for confirming the selected equipment is required between the slave station device and the central supervisory control device, it can be applied to a central monitoring control system of one behavior that does not perform communication processing for confirming equipment. There is a problem that you cannot do it.

Therefore, in the present invention, the communication processing for confirming the selected equipment is not required, and the equipment for which the setting is changed in the high-speed update cycle can be specified without increasing the burden on the administrator. The purpose is to provide a central supervisory control system that can.

[0008]

In order to solve the above-mentioned problems, the central supervisory control system of the present invention changes the measurement data of the equipment connected to the slave station device to a low-speed or high-speed update cycle. It is output to the central supervisory control device and has the following features.

That is, the central supervisory control device displays the pattern data using the measurement data of the above equipment on the screen, and the pattern No. data of this pattern data when displaying the pattern data on the screen of the CRT device. And a data output section for outputting. Further, the slave station device sets the data storage unit that stores the measurement data group corresponding to the pattern No. data and the measurement data group corresponding to the pattern No. data input from the central monitoring and control device to a high-speed update cycle. On the other hand, it is characterized by having a setting changing unit for changing the setting of the other measurement data group at a low update cycle.

[0010]

According to the above configuration, the CR of the central supervisory control device
When the pattern data is displayed on the T device on the screen, the pattern No. data attached to this pattern data is output from the central monitoring and control device to the slave station device, and the measurement data group corresponding to the pattern No. data in the slave station device. While it is possible to change the setting to a high-speed update cycle, it is possible to change the setting of other measurement data to a low-speed update cycle.

Therefore, since only the measurement data group corresponding to the pattern No. data is set to the high-speed update cycle, the load on the transmitter of the slave station device and the receiver of the central supervisory control device is slightly increased, and The traffic level of the data transmitted and received between the station device and the central supervisory control device will be maintained at an appropriate level. Therefore, urgent information data such as failure status data can be immediately taken in by the central monitoring and control device, so that it is possible to sufficiently monitor the equipment. Further, by switching the screen display of the CRT device, it is possible to set and change only the measurement data used for the screen display in a high-speed update cycle, so that the operation of selecting the equipment and designating it as the slave station device becomes unnecessary. The burden on the administrator is not increased when the setting of the update cycle is changed. Furthermore, since communication processing for confirming the equipment device selected in the high-speed update cycle is unnecessary between the slave station device and the central monitoring and control device,
It is possible to operate the central supervisory control system with a behavior that does not perform communication processing for confirming equipment.
