Abstract

A method and a system for the automated control of a technical installation (2) having a plurality of installation components (4) that are interconnected by data transmission in order to carry out process steps. Control commands (S) which are generated by a central control device (6) are fed to these components in accordance with process control signals (P) that are sent to the device. Process control signals (P) that are generated in a mobile operator unit (12) are wirelessly transmitted to interfaces (14) and are forwarded by the latter to the control device (6). The installation components (4) for which the system considers the process control signals (P) received from the mobile operator unit (12) during the generation of the corresponding control commands (S) are released using a local characteristic value (O) for the mobile operator unit (12).

Claims28

Dependent claims

A method for the automated control of a technical installation having a plurality of installation components, which are interconnected by data transmission, the method comprising:

generating process control signals in a mobile operator unit;
wirelessly transmitting to interfaces the generated process control signals;
forwarding the transmitted process control signals by the interfaces to a central control device;
receiving by the central control device the forwarded process control signals;
generating, by the central control device, control commands taking into consideration the received process control signals;
and
feeding by the central control device to at least one of the plurality of installation components the generated control commands,
wherein the installation components, for which the process control signals received from the mobile operator unit are relevant, are released when associated control commands are generated, and
wherein the installation components are released using a local characteristic value for the mobile operator unit, where the local characteristic value is determined using the interfaces which wirelessly communicate with the mobile operator unit.

6 more elements

A process control system for a technical installation, comprising:

a plurality of installation components;
a central control device that uses incoming process control signals to generate control commands for the plurality of installation components, where the control device is connected to the installation components on data output side;
a plurality of interfaces connected to the central control device on the central control device's data input side;
and
a plurality of mobile operator units connected to the plurality of interfaces on the data input side of the plurality of interfaces for transmission of the process control signals,
wherein the control device comprises a release module, which uses a local characteristic value distinctive for associated mobile operator unit from the plurality of the mobile operator units, the local characteristic value is determined via the plurality of interfaces that wirelessly communicate with the mobile operator units to assign each process control signal received from a mobile operator unit an identifier of the installation component for which the process control signal is relevant when the control commands addressed to the installation components are generated.
