Definitions

  • bus devices form common communication paths for controlling and monitoring a plurality of controlled devices and therefore represent individual critical danger points which affect all connected devices. This results in an unacceptable level of risk, since the number of devices connected to the same bus device increases both the probability of failure and the extent of the damage to be expected, because all connected devices can be affected by a defect.
  • the invention therefore relates to a control device for lighting systems in airports, for example airport lighting systems, flashing fire systems, obstacle marking and lighting systems, apron and area irradiation systems, landing lights, identification and other beacons, airport beacons, aircraft safety cable and network systems, individual lighting for aircraft lines, etc. with Controlled input parts for regulating the current supplied to the lighting devices and for equalizing the current supplied to the downstream lighting devices at the control level or when the control level changes.
  • the invention has for its object to develop the generic control device for lighting systems of airports described above such that it can meet increased requirements with regard to their operational safety and reliability and on the other hand contributes to a considerable extension of the life of its downstream lighting devices.
  • This object is achieved in that the controlled input parts associated with the control device by means of two separate, mutually independent buses Content-like control and monitoring signals can be acted on, that by means of the controlled input parts, a separate plausibility and / or conformity check of the control signals from one bus and the control signals from the other bus can be carried out, and that in the event of non-plausibility and / or non-conformity being ascertained the control signals of one or the other bus, the operation of the controlled input parts, the control signals of the other or the one bus can be used as a basis.
  • control signals from the control device according to the invention Due to the redundant introduction of the control signals from the control device according to the invention into the controlled input parts, it can be ensured that reliable and correct operation of the controlled input parts and thus of the control device is also maintained in a case in which the one or the other Busses in the controlled input parts control signals are subject to interference or falsified.
  • the plausibility check which takes place internally within the controlled input parts, it can be determined whether the control signals of one or the control signals of the other bus are falsified or disturbed. If the control signals of one or the other bus malfunction, the undisturbed control signals of the other bus are automatically taken into account when operating the controlled input parts.
  • the downstream lighting devices are thus more reliable than in the prior art with the current strength provided for them, which depends on the time of day and weather or Light conditions can vary, applied. According to the invention, the controlled input parts assigned to the control device are therefore quasi redundant
  • Multidrop bus control system which meets the increased safety and reliability requirements in today's operating conditions, since one of the two buses is automatically switched to the functioning bus in the event of a malfunction or failure.
  • Controlled input parts which are controlled and monitored by means of a bus, can be retrofitted according to the invention by means of a further bus and corresponding supplementary components. If necessary, the parameters controlled and / or monitored by the two buses of the controlled input parts can be expanded or adapted as requirements change.
  • the reliability and the economic outlay are optimized by the redundant solution with two different buses and a single input part with two different and separate inputs. Since a failure of a bus is detected by the control device, a repair or replacement can be carried out before the entire system fails.
  • the plausibility and / or conformity check of the control signals entered by the buses into the controlled input parts can expediently be carried out by means of a microprocessor, which can be designed as a simple processor and can have a separate control input for each of the two buses. If a plausibility and / or conformity check of the control signals coming from the two buses results in a fault or falsification of the control signals present at one of the two control inputs, the microprocessor automatically switches over to the control input at which those control signals are present, their plausibility and / or Conformity check has led to a positive result.
  • the microprocessor of the controlled input parts of the control device expediently has a digital control input for one bus and a serial control input for the other bus.
  • the control inputs of the microprocessor are dual and are isolated from one another. The isolation of the two control inputs from one another prevents systematic damage to both control inputs, the isolation of the two control inputs also acting against earth and against the further microprocessor circuits.
  • the digital control input of the microprocessor is preceded by an asynchronous receiver / transmitter, the output signals of which are fed to the digital control input of the microprocessor and which is preceded by a transmitter / receiver which is galvanically isolated, works dual and on a first bus input assigned to a bus is connected.
  • the serial control input of the microprocessor is preceded by a further transmitter / receiver, which is galvanically isolated, works dual and is connected to a second bus input assigned to the other bus.
  • the further transmitter / receiver can be designed more or less identically with the first-mentioned transmitter / receiver, which is assigned to the digital control input of the microprocessor. Due to the asymmetrical design of the input areas of the microprocessor assigned to the digital or serial control input, despite the largely identical design of the two transmitters / receivers, there is, if at all, only a very low probability that a total failure will occur in the event of a limit signal.
  • the microprocessor, the asynchronous receiver / transmitter, the two transmitters / receivers and the two can be advantageous Bus inputs can be implemented as part of a flat module, which in turn can be easily installed. If the controlled input part is reset to the operating state which is provided in the event that both buses operate without interference, with the control signals of one or the other bus being used as the basis for the operation of the controlled input part, then it is ensured that always then, if it is possible, the controlled input part works in the safest mode of operation.
  • controlled input parts of the control device according to the invention are designed as work units of a control and monitoring circuit having a plurality of such controlled input parts designed as work units, a main unit being installed on a substation of the control and monitoring circuit, of which the individual work units are installed by means of the two buses can be called up at predefinable times for status information and control, highly functional and reliable control and monitoring circuits for very large and complicated systems can be implemented with comparatively little technical effort.
  • the controlled input parts of the control device according to the invention are components of a control and monitoring circuit whose components upstream of the controlled input parts are of redundant design, this control and monitoring circuit can be made extremely reliable, although only one microprocessor is provided within each of the controlled input parts , which can be a comparatively simple communication processor.
  • conventional field buses for example MOD buses, PROFI buses, CAN buses or the like, can be used with the controlled input parts of the control device according to the invention. This and the availability of comparatively less expensive telecommunication and computer technology make it possible to manufacture the control device according to the invention with a comparatively low and accordingly justifiable economic outlay.
  • the controlled input parts of the control device according to the invention can be combined with different consumers, e.g. with switching devices, high voltage devices, irrigation controls, fuel controls and the like.
  • a control device equipped with these controlled input parts is very flexible, since the controlled input parts can be used to regulate and monitor different downstream lighting devices provided in a local area, the control of these different lighting devices using the same two buses or one of these both buses can be made.

Abstract

L'invention concerne un dispositif de commande destiné aux installations d'éclairage d'aéroports. Ce dispositif permet de régler le courant délivré aux équipements d'éclairage montés en aval et de l'égaliser au niveau réglé ou en cas de modification du niveau de réglage. Pour concevoir un tel dispositif de commande avec un fonctionnement plus sûr et plus fiable, des parties d'entrée commandées des équipements d'éclairage peuvent être alimentées avec les signaux de commande et de surveillance de contenu semblable par deux bus (3, 4) séparés et indépendants l'un de l'autre. Les parties d'entrée commandées permettent de réaliser séparément un test de plausibilité et/ou de conformité des signaux de commande provenant d'un bus (3) et des signaux de commande provenant de l'autre bus (4). En cas de non plausibilité et/ou de non-conformité des signaux de commande de l'un (3) ou de l'autre bus (4), les signaux de commande respectivement du second bus (4) ou du premier bus (3) peuvent servir de base au fonctionnement des parties d'entrée commandées.
