Abstract
The invention relates to a synchronization control method for a substation of a distributed industrial control system. A host computer sends out a system synchronization signal when sending out communication data. The system synchronization signal can be received by all of the substations in the system. The system synchronization signal is synchronization characteristic data which may be a byte, a data section or a data package. The synchronization signal transmitted by the host computer can be sent to a control bus separately, and embedded into a data stream sent by the host computer. The time coordinate can be rectified while the substations in the control system receive the synchronization signal, thereby data processing and control output can be carried out according to a preset requirement.
Description
Technical field
The present invention relates to a kind of synchronisation control means, the synchronisation control means of particularly a kind of distributed industrial control system substation.
Background technology
At present, distributed industrial control system when equipment room needs accurately unified in time control, must be undertaken by the unification of same substation.If in the control system of networking, because the exchanges data of each website needs certain hour, control action will delay according to exchange by factor.
Summary of the invention
The synchronisation control means that the purpose of this invention is to provide a kind of distributed industrial control system substation.Utilize this method, in the control system of networking, each control sub-station can keep accurate controlled step uniformly in time after exchanges data finishes.To reach the synchro control purpose of large-scale scattered control system.
For achieving the above object, the technical scheme that the synchronisation control means of the distributed industrial control system of the present invention substation adopts is: send communication data at host computer and send a system synchronization signal therebetween, the system synchronization signal is to be received simultaneously by all substations in the system.The system synchronization signal is a synchronize feature data, and it can be that a byte also can be a data segment, also can be a packet.The synchronizing signal that host computer sends can send to control bus separately, also can embed in the upper data stream of sending.Each substation receives the moment of synchronizing signal in the control system, and just energy improvement time coordinate carries out data processing and control output by pre-provisioning request.
Base was unified when the synchronisation control means of the distributed industrial control system of the present invention substation reached the control of full control system, made industrial control system accurate more and in time.Reach the purpose that improves the industrial control system performance.
The invention has the beneficial effects as follows: guaranteed the coordinated manipulation of large-scale control system, improved control efficiency, reduced and controlled cost.
Description of drawings
Fig. 1 is the synchronisation control means schematic diagram of the distributed industrial control system of the present invention substation.
Fig. 2 is that the synchronisation control means substation of the distributed industrial control system of the present invention substation receives the data schematic diagram.
Embodiment
In Fig. 1, host computer sends communication data therebetween, and elder generation is transmission control system data down, and then passes synchronizing signal down.
In Fig. 2, after the substation receives control data, receive synchronizing signal again through data manipulation and after waiting for.
Claims (3)
1. the synchronisation control means of a distributed industrial control system substation, it is characterized in that: send communication data at host computer and send a system synchronization signal therebetween, the system synchronization signal is to be received simultaneously by all substations in the system.
2. by the synchronisation control means of the described distributed industrial control system of claim 1 substation, it is characterized in that: the system synchronization signal is a synchronize feature data, and it can be that a byte also can be a data segment, also can be a packet.
3. by the synchronisation control means of the described distributed industrial control system of claim 1 substation, it is characterized in that: the synchronizing signal that host computer sends can send to control bus separately, also can embed in the upper data stream of sending.
