Definitions

  • the invention relates to process connections for the safe operation of security equipment according to the preamble of claim 1.
  • process connections are required in many fields of technology with safety-relevant orientation, such as vehicle construction, traffic control and monitoring, industrial plant construction and medical technology.
  • control elements of the electronic interlockings control a variety of components of the indoor unit and the exterior of the interlocking.
  • the adaptation to different configurations, local conditions and various components of the interlocking system requires a large number of very complex and specific actuator subassemblies.
  • considerable effort is required in particular the unbundling, the change of documents, a new safety case management and the validation of the change to realize.
  • the number of actuators and generally the process connections grows continuously and thus increases the care required, the u. a. caused by component discontinuation. The trend is towards ever more complex and customized special solutions.
  • US Pat. No. 5,922,034 discloses process connections or steep parts which are based on PRD (Programmable Relay Driver). Technology based. Various PRDs are provided for controlling various devices, such as lamps, motors or switches.
  • the invention is based on the object process connections of the generic type 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 finding 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 verification.
  • the range of modules can be easily expanded according to the architectural specifications. For example, the complete range of actuators for electronic interlockings with about 15 different function modules can be realized.
  • the modular design allows for prefabrication of the functional modules, resulting in ultimately shorter production times, a more balanced production utilization and shorter delivery times.
  • the safety record guide is also much easier and faster.
  • the testing machines for the functional modules in production are small, inexpensive and faster to implement the test programs.
  • the test time can be reduced many times over with the module technology.
  • a safety case is created for each functional module.
  • the interaction between the function modules is defined by a method security proof.
  • the individual safety proofs of the function modules are included in a complete safety record embedded for the respective process connection.
  • the cost of the safety verification guide over conventional process connections is significantly reduced.
  • Functional modules which are designed as electronic fuses, according to the invention for overload protection and line monitoring have a switching threshold, which can be configured by software.
  • the current to be monitored is configured in software for several current ranges.
  • the usual conventional fuses are replaced by the configurable electronic fuses.
  • the state of the electronic fuse can be signaled by an LED. With a push-button, the circuit can be switched off and on again. This results in an essential functionality to achieve the modularity. Process switch-specific or part-specific fuses are no longer required.
  • the size of the volume of a function module for actuators should be 45 mm x 30 mm x 20 mm. Only the small secure computer, which is listed in claim 2 in addition to other function modules, requires about twice the volume. The small cheap secure calculator in Configuration with other function modules enables a significant reduction of material consumption. By concentrating and encapsulating the functionalities on a few function modules, the number of different components is reduced, which at the same time increases the number of required components. The temporal signal changes on the connections between the function modules can be greater by powers than in conventional actuators, so that the control parts are less susceptible to interference.
  • the function module functioning as communication interface is used for communication with a higher-level computer or with neighboring computers.
  • the function module can be designed, for example, for ISDN Uo, PROFIBUS, TCP / IP or radio communication.
  • Function modules in the embodiment as a circuit breaker are preferably designed with integrated current transformer. Different circuit breakers are controlled according to the same principle. For the timely control, a safe computer in modular technology is provided with a powerful Stormbeêt.
  • the function modules also contain mechanisms to detect wire contacts.
  • the current to be monitored in particular in the case of the circuit breakers and in the case of the secure computer, is configured according to the invention in terms of software for a plurality of current ranges.
  • each circuit breaker can monitor four switch-specific current ranges.
  • the current ranges are loaded during initialization.
  • the circuit breakers can be used in a large current and voltage range.
  • the number of required function modules is minimized. At the same time, fewer different process connections are required.
  • the functional modules are shed according to claim 4, whereby a reduced influence of moisture and improved insulation result. This has a positive effect on the dielectric strength of the function modules.
  • the function modules which are to be combined to form an actuating part, are electrically connected with each other.
  • FIG. 1 schematically shows the development of an actuating part 1 from functionalities Fkt_1, Fkt_2, Fkt... In a first grouping 2 and functional modules 3 in a second grouping 4.
  • the functionalities Fkt_1, Fkt_2, Fkt Number of functional modules 3 encapsulated such that functionalities Fkt_1, Fkt_2, Fkt ... for similar objectives, such as certain current ranges, are summarized in a controllable by software electronic function module 3.
  • the control part 1 is assembled.
  • the function module 3 as a secure computer 5, communication interface 6 or be designed as a circuit breaker 7.
  • the module-based actuator 1 is characterized by shorter production times, simplified testing, reduced complexity, reduced maintenance costs, reduced material costs and reduced space requirements.
  • the direct assembly of the control components from the very large number of functionalities Fkt_1, Fkt_2, Fkt ... with lower projectability and increased costs.
  • FIG. 2 illustrates a system configuration for a process interface 8 in cooperation with a two-channel computer 5.
  • the communication interfaces 6 include a function module 3 for ISDN connection, TCP / IP and / or for connection to a redundant Profibus.
  • the communication interfaces 6 are each connected to a functional module 3, which represents the secure computer 5. From the computer modules 5 a plurality of functional modules 3 are controlled for circuit breaker 7.
  • the circuit breaker modules 7 switch a load 9, for example a signal control, as illustrated in FIG. 3 or a four-wire point drive, as illustrated in FIG.
  • the functional modules 3 for the circuit breaker 7 may be preceded if necessary, a test module 10.
  • the test module drives a constant current of z. B. 10 mA.
  • the test current z. B every 100 ms for a few ms to be turned on. In this way, results in a very low power loss.
  • the functional modules 3 for the circuit breaker 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 by an LED on the front panel of the process interface 8 is displayed.
  • the circuit can be switched on again with an associated button on the front panel.
  • This functionality is realized by electronic fuses whose switching threshold can be configured by software.
  • FIG. 3 shows an actuating part for controlling signal lamps 11.1, 11.2 and 11.3.
  • the signal lamp 11.3 is a red lamp, which is particularly secured by means of a function module 3 for a switch-off relay 12 to guarantee the associated, particularly safety-relevant Gargebot in each case.
  • FIG. 4 shows a further example of the modular construction of an actuating part which is provided for the control of a four-wire point drive 13.
  • FIG. 5 shows a current range diagram for a function module 3 for the power circuit 7.
  • the current ranges 14.1, 14.2, 14.3 and 14.4, which are shown in a window-like manner for the sake of clarity, can be configured by software. In this case, an overlap of current ranges, in the embodiment 14.2 and 14.3, possible.
  • the second current range 14.2 symbolizes the current range at night voltage
  • the third current range 14.3 symbolizes the current range at day voltage
  • the fourth current range 14.4 which corresponds to the highest power consumption, becomes effective in the case of overcurrent, the associated load switch after a configurable period of time, for example 10 ms, is opened.
