Definitions

  • the invention relates to process connections for the safe operation of safety devices according to the preamble of claim 1.
  • Process connections of this type are required in many areas of technology with a safety-related orientation, for example vehicle construction, traffic control and monitoring, industrial plant construction and medical technology.
  • control elements of the electronic signal boxes control a large number of components of the indoor and outdoor systems of the signal box.
  • the adaptation to different configurations, local conditions and different components of the signal box system requires a large number of very complex and specific control component assemblies.
  • considerable effort is required, in particular to implement the unbundling, the change in the documents, a new safety record keeping and the validation of the change.
  • the number of actuators and process connections in general grows continuously and thus also increases the maintenance effort, which u. a. is caused by component discontinuation.
  • the trend is towards increasingly complex and customer-specific special solutions.
  • the invention has for its object to eliminate these problems and process connections of the generic type to be specified, which are characterized by greater projectability, ie a reduction in the number of variants.
  • the object is achieved with the characterizing features of claim 1.
  • the invention is based on the knowledge that the sum of the functionalities of all process connections can be mapped to only a few basic functionalities.
  • An electronic function module is defined for each basic functionality.
  • a higher-level architecture defines the functionality, the structure and the interaction of the function modules, in particular with regard to interfaces, form and safety record keeping.
  • the range of modules can be easily expanded in accordance with the architectural specifications. For example, the complete range of control parts for electronic signal boxes can be realized with approx. 15 different function modules.
  • the modular design enables the functional modules to be prefabricated, so that ultimately shorter production times, a more balanced production load and shorter delivery times result.
  • the safety record keeping is also much easier and faster.
  • a safety certificate is created for each function module.
  • the interaction between the function modules is defined by a procedural safety certificate.
  • the individual safety certificates of the function modules are Evidence of safety for the respective process connection embedded. This significantly reduces the effort required for safety verification compared to conventional process connections.
  • the function module which functions as a communication interface, is used for communication with a higher-level computer or with neighboring computers.
  • the function module can For example, be designed for ISDN Uo, PROFIBUS, TCP / IP or radio communication.
  • Function modules in the embodiment as a circuit breaker are preferably designed with an integrated current transformer. Different circuit breakers are controlled according to the same principle. A safe computer in modular technology with a powerful storm evaluation is provided for precise timing.
  • the function modules may also contain mechanisms to detect wire contact.
  • electronic fuses are provided as an overload contactor and as line monitoring with a switching threshold that can be configured by software.
  • the current to be monitored is configured in software for several current windows.
  • the conventional fuses previously used are replaced by the configurable electronic fuses.
  • the status of the electronic fuse can be signaled by an LED.
  • the circuit can be switched off and on again with a button. This results in an essential functionality to achieve the modularity. Process interface-specific or part-specific fuses are no longer required.
  • the current to be monitored in particular in the case of the circuit breakers and in the safe computer is configured according to claim 4 in software for several current windows.
  • each circuit breaker can monitor four switch-specific current windows.
  • the current windows are loaded during initialization. This means that the circuit breakers can be used in a wide range of currents and voltages. The The number of required function modules is minimized.
  • the functional modules are encapsulated according to claim 5, which results in a reduced influence of moisture and improved insulation. This has a positive effect on the dielectric strength of the function modules.
  • the function modules that are to be combined to form an actuator are electrically connected to each other.
  • FIG. 1 shows a schematic illustration of the module concept
  • FIG. 2 shows a system configuration
  • FIG. 3 shows a power section of an actuator for a signal connection
  • FIG. 4 shows a power section of an actuator for a point machine
  • Figure 5 is a current window diagram.
  • Figure 1 shows schematically the development of an actuator 1 from functionalities Fkt_l, Fkt_2, Fkt ... in a first grouping 2 and function modules 3 in a second grouping 4.
  • the functionalities Fkt_l, Fkt_2, Fkt ... become much less Number of function modules 3 encapsulated in such a way that functionalities Fkt_l, Fkt_2, Fkt ... for similar objectives, for example certain current ranges, in an electronic software-controllable
  • the actuator 1 is assembled from various module components.
  • the function module 3 can be used as a secure computer 5, communication interface 6 or be designed as a circuit breaker 7.
  • Actuator 1 on a module basis is characterized by shorter production times, simplified testing, reduced complexity, reduced maintenance, reduced material costs and reduced space requirements.
  • the direct assembly of the control component from the very large number of functionalities Fkt_l, Fkt_2, Fkt ... is associated with less configuration and increased costs.
  • FIG. 2 illustrates a system configuration for a process interface 8 in cooperation with a two-channel computer 5.
  • a function module 3 for ISDN connection, TCP / IP and / or for connection to a redundant Profibus is provided as communication interfaces 6.
  • the communication interfaces 6 are each connected to a function module 3, which represents the secure computer 5.
  • Several function modules 3 for circuit breakers 7 are controlled by the computer modules 5.
  • the circuit breaker modules 7 switch a load 9, for example a signal control as illustrated in FIG. 3 or a four-wire switch drive as illustrated in FIG. 4.
  • a test module 10 can be connected upstream of the function modules 3 for the circuit breakers 7.
  • the test module drives a constant current of e.g. B. 10 mA.
  • the test current z. B. be switched on every 100 ms for a few ms. This results in a very low power loss.
  • the function modules 3 for the circuit breakers 7 are opened after a configurable period of time, for example 20 ms.
  • the circuit breaker 7 is opened within 1 ms. The shutdown is activated by an LED on the front panel of the process device 8 is displayed. The circuit can be switched on again with an associated button on the front panel. This
  • Switching threshold can be configured by software.
  • Figure 3 shows an actuator for controlling signal lamps
  • the signal lamp 11.3 is a red lamp, which is specially protected for a switch-off relay 12 by means of a function module 3 in order to guarantee the assigned, particularly safety-relevant stopping requirement in any case.
  • Figure 4 shows another example of the modular structure of an actuator, which is provided for the control of a four-wire switch drive 13.
  • FIG. 5 shows a current window diagram for a function module 3 for power switching 7.
  • the current windows 14.1 are a current window diagram for a function module 3 for power switching 7.
  • the 14.2, 14.3 and 14.4 can be configured using software. An overlap of current windows, in the exemplary embodiment 14.2 and 14.3, is also possible.
  • the first current window 14.1, which corresponds to the lowest power consumption, can e.g. B. be provided for a test current
  • the second current window 14.2 symbolizes the current range at night voltage
  • the third current window 14.3 symbolizes the current range at daytime voltage
  • the fourth current window 14.4, which corresponds to the highest power consumption is effective in the event of overcurrent, the associated load switch after one configurable period of time, for example 10 ms, is opened.
  • the invention is not limited to the exemplary embodiments specified above. Rather, a number of variants are conceivable, which are also fundamentally different. Make use of the features of the invention.
