Abstract

PURPOSE:To monitor always the state of remaining of trouble items or the like by adding a remaining display circuit and displaying whether object equipments of every slave station are left turned on or not and whether every item of the whole of a system is left turned on or not when a slave station selecting switch selects no slave stations. CONSTITUTION:Display signal items A-Z of a slave station 7 are stored temporarily in a reception storage circuit 10 after reception processing in a master station receiving circuit 3 and is outputted to a remaining display circuit 1 and a selection display circuit 2. The selection display circuit 2 displays out turn- on states of items A-Z of a pertinent slave station on item indicators 5 in accordance with the turn-on condition of a slave station selecting switch 4 and turns off the display output in accordance with the turn-off condition of the switch 4. Meanwhile, the remaining display circuit 1 operates OR among item display signals A-Z of each of slave stations 1-(n) and displays out results on slave station indicators 6. Thus, information, which indicates whether items are left turned on in each slave station or not, is always displayed on slave station indicators 6.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for displaying the status of target equipment in a master station of a centralized monitoring system, and particularly relates to a method for displaying the status f of multiple slave stations on a reduced panel. The present invention relates to a display method suitable for a required wide-area 1:N centralized monitoring system.

[Background of the invention]

Conventional display methods include a selective display method and a constant display method.

The selection display method will be explained with reference to FIG. The display signal items A to Z of the slave stations 1 to n of 7 are received and processed by the master station receiving circuit 3, stored in the reception storage circuit 10, and output to the selection display circuit 2. Ru. In the selection display circuit 2,
Depending on the ON condition of the slave station selection switch 4, the status of items A to 2 of the slave station is displayed and displayed on the item display 5.

Also, depending on the condition that the slave station selection switch is OFF, the item display is turned off.

The selection display method is a method in which the item display common to multiple slave stations shows the status 1 of the equipment item of the slave station only when a slave station is selected.Since the item display is provided in common to multiple slave stations, the screen size can be reduced. However, since the item status of all equipment cannot be displayed at once, it is difficult to monitor the remaining status of failure items, etc., and operators may forget the failure status and failures may be left as they are. There is.

On the other hand, the constant display method is a method that constantly displays the status of equipment items on individual item indicators for all equipment.Although the status of all equipment items can be displayed at once, As the system size increases, the board surface will expand. Additionally, as the panel surface expands and the number of item displays increases, there is a problem in that multiple operators must be assigned to prevent operators from overlooking monitoring.

[Purpose of the invention]

The purpose of this stage is to add all residual display circuits to display whether or not the target equipment remains in the ON state for each slave station and whether or not the ON state remains for each item in the entire system when the slave station selection switch is not selected. To provide a display method for a centralized monitoring system that enables constant monitoring of residual conditions such as failure items, reduces the size of the panel, and is easy to operate.

[Embodiments of the invention]

An embodiment of the present invention will be explained with reference to the block diagrams of FIGS. 2 and 3.

After the display signal items A to Z of the slave station 7 have been received and processed by the master station receiving circuit 3, they are partially stored in the receiving storage circuit 1o and output to the residual display circuit 1 and the selection display circuit 2. In the selection display circuit 2, depending on the ON condition of the slave station selection switch 4, the ON status of items A to Z of the corresponding slave station is displayed and output to the item display 5, and the 0FIi' condition of the slave station selection switch 4 is output. Now, turn off the display output. On the other hand, the residual display circuit 1 outputs the item display signals A-Z of the slave stations 1 to n for each slave station for display on the slave station display 6. Whether or not the status remains is constantly displayed on the slave station display 6.In addition, the item display signal A- of slave stations 1 to n
Set Z to L for each item and set this to slave station selection switch 4.
The display is output under the condition that all are OFF.

As a result, whether or not each item remains in the ON state in the entire system can be displayed on the item display.

As a specific embodiment of the present invention, according to the block diagram of FIG. 4 and the flowchart of FIG.
The case where a self-generated failure occurs in slave station B will be explained below as an example.

The occurrence of a power reception failure in the slave station A and the occurrence of a self-generation failure in the slave station B are stored in the reception storage circuit 10 via the master station reception circuit 3, and then output to the residual display circuit 1 and the selection display circuit 2. In this case, there are items in the ON state on slave station A and slave station B, so
The residual display circuit 1 outputs slave station display signals for the slave stations A and B, and the A and B lights of the slave station display 6 are lit. Also, since the power reception failure and private generation failure are ON, the power reception failure display signal and the private generation failure display signal are output, and when the power reception failure and private generation failure on the item display 5 lights up, the slave station A is selected. When the switch 1 tuner 4i is turned on, the output from the residual display circuit 1 is interrupted, and the selection display circuit 2 outputs a power reception failure display signal to the slave station, and only the power reception failure is displayed on the item display 5, and the slave station You can check the item status of station A. Similarly, when the selection switch 4 of the slave station B is turned on, only the self-generated failure is displayed on the item display 5 as an item status display of the slave station B. Checking the item status of each slave station When the slave station selection switch e is turned OFF, the output is switched to the selection display circuit 2, and the output from the residual display circuit 1 is displayed on the item display 5 as a display of the item status of the entire system. , power reception failure, private power failure are lit.

[Summary of the Invention] We have conducted studies to meet the needs of being able to constantly monitor item statuses with a compact configuration and also be able to confirm detailed item statuses. We focused on the fact that the purpose of monitoring for failures is to monitor whether or not they have occurred rather than constantly monitoring individual conditions, and that in the selection display method, the item display disappears when no selection is made and becomes an idle state. Make effective use of this idle state, and during this time, it will be passed to each slave station/ζ The presence or absence of a failure will be displayed on the item display, and the presence or absence of a failure state for each slave station will be displayed on the slave station. This is displayed on the display, making it possible to constantly monitor the presence or absence of failures and to monitor detailed items through selective display with a compact configuration.

〔Effect of the invention〕

According to the present invention, (1) Since the item status of multiple slave stations can be constantly monitored by the item display for one slave station, the board size can be reduced to 6 and the configuration can be made at low cost.

(2) Information on multiple slave stations can be constantly monitored on a simple display panel using a common display, and detailed items can also be checked, making monitoring easy to operate.
