Abstract

PURPOSE:To receive efficiently supervisory information by polling from plural supervisory boards by providing a system supervisory board comprising a polling signal sending means, an information edit means and an information sending means and plural supervisory boards to a centralized supervisory center. CONSTITUTION:When a polling signal sending means 101 of a system supervisory board 10 commands a polling to each terminal station, the polling is started via a prescribed supervisory board. The information from a terminal station is received by the said supervisory board and sent to an edit means 102 of the supervisory board 10 via a bus 17. The edit output is sent to all supervisory boards 11, 12... by a sending means 103. Then the supervisory board 10 allows other supervisory board to start the polling. The information at such a time is edited again and sent to all the supervisory boards. Thus, each supervisory board can always obtain the updated information of the terminal station. Thus, all the supervisory board can always know the updated information of all terminal stations.

Description

[Detailed Description of the Invention] [Summary] Monitoring information of multiple terminal stations can be efficiently received (received and displayed on multiple monitoring consoles) by controlling a system monitoring stand installed in a centralized monitoring center. This is an information receiving method.

[Industrial Field of Application] The present invention relates to a system for receiving monitoring information of a terminal station, which efficiently receives monitoring information of a plurality of terminal stations by installing a system monitoring stand in a centralized monitoring center and polling the system.

[Prior Art] A monitoring system in which information from a plurality of terminal stations is displayed simultaneously in a centralized monitoring center has a configuration shown in FIG. In FIG. 4, the central monitoring center 1 includes a system monitoring stand 10 and a plurality of monitoring stands 11, 12. - and they are connected by a bus 17. An alarm lamp 18 and a bell 19 are connected to the system monitoring stand 10. 21 to 2n are terminal stations, which are connected to data link controllers 31, 32, . . . via several data transmission central stations 41, 42. Initially, the system monitoring stand 10 issues one order to the monitoring stand 11, makes a polling request to all terminal stations, and asks for the presence or absence of alarm information. When alarm information occurs, the alarm lamp 18 and bell 19 operate.

At this time, there is no path set between the monitoring station 12 and below with the terminal station, and there is no order from the system monitoring station, so I want to know the data about the terminal station, but I have to wait until the monitoring station IO operation is finished. . When the monitoring stand 12 performs a polling operation, the monitoring stands 10 and 13 and the following are made to wait. The monitoring stand needs to be set and changed regarding the status of a specific terminal station, and may monopolize the area between a given monitoring stand and the terminal station for a while, so the central monitoring center 1 is equipped with multiple monitoring stands. are doing.

[Problems to be Solved by the Invention] Regarding the configuration shown in FIG. 4, when the monitoring stand 11 polls a certain terminal station, the other monitoring stand performs polling next, so that the monitoring stand 11 does not have to be the same again. Naturally, the polling cycle (monitoring cycle) until polling the terminal station has become longer. As the number of terminals and monitoring stations increases, the polling cycle becomes longer and the monitoring efficiency deteriorates.

In addition, if you try to monitor all stations simultaneously with multiple monitoring stations, for example, when the status information of terminal station 21 at time TI polled from monitoring station 11 is "HMM" and polled from monitoring station 12, If the status information becomes "HNN", the status information will no longer be the same, making it difficult to process on the system monitoring stand 10.

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned drawbacks and provide a system for efficiently receiving monitoring information by polling from a plurality of monitoring stations.

[Means for Solving the Problem] FIG. 1 is a diagram showing the configuration of the present invention. In FIG. 1, 1 is a central monitoring center, 10 is a system monitoring stand, 101 is a polling signal sending means, 102 is a means for editing information from a terminal station, and 103 is a means for sending the output of the editing means 102 to each monitoring stand. , 11.12...- is a monitoring stand, 17 is a connection bus, 18 is a lamp, 19 is a bell, 31.32- is a digital link controller, 21.22...
indicates a terminal station.

[Function] System monitoring stand 1O and digicle link controller 3
1.32- and each monitoring stand are connected by the connection bus 17, so when the polling signal sending means 101 of the system monitoring stand 10 instructs polling to each terminal station, the polling signal is sent via the specified monitoring stand. Polling begins.

The information from the end station is received by the monitoring station concerned and then sent to the editing means 102 of the system monitoring station 10 via the connection bus 17.
transmitted to. After editing the information on the system monitor, the edited output is sent to all monitors 11 by the transmitting means 103.
12... is sent. When there is an alarm in the information, the lamp 18 and bell 19 are activated on the system monitoring stand 10.
Notify maintenance personnel.

Next, the system monitor 10 starts polling from a different monitor than the one mentioned above. The information at that time is edited again by the editing means 102 and sent to all monitoring stations. Therefore, each monitoring station can always obtain the latest information of the terminal station.

[Embodiment] FIG. 2 shows an embodiment of the present invention, in which the same reference numerals as in FIG. 1 indicate the same components, and connections to terminal stations are omitted. #
0. #1 indicates the 0 system and 1 system, respectively, indicating a duplex configuration. ADLCO and ADLCI represent data link control units, CC represents a central processing unit, and SDR represents a received signal distribution device. FIG. 3 shows an operating diagram for FIG.

The upper half shows the situation when the monitoring stand #0 acts as a mask and polls to the terminal station #0, and the lower half shows the situation when the monitoring stand #1 acts as a mask and polls to the terminal station #1. It can be seen that in both cases, the O system cannot be used for the digital controller, and the 1 system is used. The alarm information from the polling end station #0 is sent to the system monitoring stand 10.
and its output is sent to all monitoring stations.

The operation in the lower half of FIG. 3 shows a case where the data is sent to monitoring stand #1, which has become a mask after editing, and is retransmitted from #1 to other monitoring stands.

[Effects of the Invention] In this way, according to the present invention, the system monitoring stand controls the bus-connected monitoring stand and the digital link controller to perform polling, and the obtained information is transmitted to the monitoring stand other than the masked monitoring stand. sent to all monitoring stations. Therefore, all monitoring stations can always know the latest information of all terminal stations.
