Abstract

In order to provide a system (1) for monitoring, control and data acquisition of technical processes, comprising at least one communication unit (12) as an interface for bidirectional data exchange with external units (2, 3), which allows comprehensive monitoring, control and data acquisition of a technical process incorporating additional far-from process data, it is proposed that at least one communication unit (12) is configured for communication with at least one external electronic process database (3) and at least one communication unit (12) is configured for communication with at least one external technical control unit (2).

Claims

1. A system (1) for monitoring, control and data acquisition of technical processes, comprising at least one communication unit (12) as an interface for bidirectional data exchange with external units (2, 3), characterised in that at least one communication unit (12) is configured for communication with at least one external electronic process database (3) and at least one communication unit (12) is configured for communication with at least one external technical control unit (2).

2. The system (1) according to claim 1, characterised in that the communication unit (12) is configured for addressing any external unit (2, 3) by means of a unique identifier, wherein identifiers for process databases (3) are configured to be referencing to their primary key and identifiers for control units (2) are configured to be referencing to a memory address.

3. The system (1) according to claim 1, characterised in that a communication channel database (21, 24, 25, 102, 104, 105, 106, 107) is provided in which identifiers for communication with external units (2, 3) are stored.

4. The system (1) according to claim 1, characterised in that the communication unit (12) is configured for addressing memory regions on external units (2, 3) according to a standard format for all external units (2, 3), in particular SQL format.

5. The system (1) according to claim 1, characterised in that a data structure database (22) is provided, in which data structures (26, 27, 28, 29, 35, 36, 37, 38) of external units (2, 3) connectable to the system are stored.

6. The system (1) according to claim 1, characterised in that means for checking a data compatibility, in particular with regard to a data format and/or a data width, are provided between elements of the data structure database (22) and elements of the communication channel database (21, 24, 25, 102, 104, 105, 106, 107).

7. The system (1) according to claim 1, characterised in that a connection database (23) is provided in which desired compatible pairs of elements of the data structure database (22) and elements of the communication channel database (21, 24, 25, 102, 104, 105, 106, 107) are stored.

8. The system (1) according to claim 1, characterised in that a link database is provided for storing links between process data from a process database (3) and measurement data from a technical control unit (2) for the purpose of visualising said data.

9. A method for monitoring, control and data acquisition of technical processes by means of bidirectional data exchange with external units (2, 3), characterised in that data exchange is carried out with at least one external electronic process database (3) and at least one external technical control unit (2).

10. The method according to claim 9, characterised in that each external unit (2, 3) is addressed by means of a unique identifier, wherein identifiers for process databases (3) are formed from their primary key and identifiers for control units (2) are formed from a memory address.

11. The method according to claim 9, characterised in that identifiers for data exchange with external units (2, 3) are stored before the beginning of monitoring, control and data acquisition in a communication channel database (21, 24, 25, 102, 104, 105, 106, 107).

12. The method according to claim 9, characterised in that memory regions on external units (2, 3) are addressed according to a standard format for all external units (2, 3), in particular SQL format.

13. The method according to claim 9, characterised in that before each data exchange at least one data structure (26, 27, 28, 29, 35, 36, 37, 38) of external units (2, 3) connectable to a system (1) is read out from a data structure database (22) and before each data exchange, a data compatibility, particularly with regard to a data format and/or a data width, is checked between elements of a data structure database (22) and elements of a communication channel database (21, 24, 25, 102, 104, 105, 106, 107), wherein a data exchange is exclusively carried out between compatible elements.

14. The method according to claim 9, characterised in that process data are read out from at least one external process database (3) and measurement data are read out from at least one external technical control unit (2) and are interlinked for visualisation.
