監視制御システムにおける制御排他方式に関する。[Detailed Description of the Invention] Technical Field The present invention relates to a control exclusive method in a remote monitoring and control system, and in particular, to a system in which a controlled station is subordinately controlled by control from one of a plurality of control stations. This invention relates to a control exclusion method in a remote monitoring and control system.
従来技術
従来のこの種の制御方式では、複数制御局相互の制御権
交換手続きによって、被制御局の制御を行う制御局を決
定するという制御排他方式が採用されている。Prior Art This type of conventional control system employs a control exclusion system in which a control station that controls a controlled station is determined through a procedure for exchanging control rights between a plurality of control stations.
上述した従来の制御排他方式は、複数制御局間相互によ

御が重複するという欠点がある。また、制御局が多数と
なった場合、制御権交換手続が複雑となるという欠点が
ある。In the conventional control exclusion method described above, control rights are mutually exchanged between multiple control stations, so if one control station is unable to perform the control rights exchange procedure with another control station, control overlaps. There is a drawback. Furthermore, when there are a large number of control stations, there is a drawback that the control right exchange procedure becomes complicated.
発明の目的
本発明の目的は、制御の重複を確実に排除し得ると共に
、制御権交換手続が極めて簡単な制御排他方式を提供す
ることである。OBJECTS OF THE INVENTION An object of the present invention is to provide a control exclusion system that can reliably eliminate duplication of control and has an extremely simple control exchange procedure.

徴とする制御排他方式が得られる。Structure of the Invention According to the present invention, there is provided a control exclusive method in a remote monitoring and control system configured such that a controlled station is subordinately controlled by control from one of a plurality of control stations. A storage means is provided in the control station to store in advance subordinate control station information for specifying a control station to which this controlled station is subject to subordinate control, and receives control information from the control station and controls the received control. A control exclusion system is obtained in which, when the station information and the dependent control station information stored in the storage means match, control of stations other than the control station at that time is excluded.

等制御局ＩＡ〜ＩＮと被制御局３を結ぶ通信路である。FIG. 2 is a system configuration diagram of a remote monitoring system to which the present invention is applied. In the figure, control stations IA to IN are a plurality of control stations that perform control, and controlled stations 3 are control stations IA to IN.
It is a dependent station that is controlled by the IN. The communication path 2 is a communication path that connects these control stations IA to IN and the controlled station 3.
制御を行おうとする制御局は通信路２を介し制御情報を
被制御局に送出する。A control station that wishes to perform control sends control information to a controlled station via a communication path 2.

制御情報を主制御部５は無視する。FIG. 1 is a functional diagram of an embodiment of a controlled station of the present invention. A communication processing unit 4 receives a control signal sent from a control station and converts it into control information that can be handled by other control units. Main control unit 5
checks which control station this control information was sent from,
The slave control station information is compared with the slave control station information held in the slave control station information unit 6, and control is performed via the control output unit 8 only when the mutual information matches. If they do not match, the main control unit 5 ignores the control information sent from the control station.

It has a function of automatically changing the information of the unit 6 to control station information of the next priority.
