20、Convention on International Civil Aviation, paragraph 8.2 Electrical Systems and paragraph 8.3 Monitoring, presents provisions, either as international standards or recommended practices, regarding control and monitoring systems for visual aids: “A system of monitoring visual aids should be employed

21、 to ensure lighting system reliability. Where lighting systems are used for aircraft control purposes, such systems should be monitored automatically so as to provide an immediate indication of any fault which may affect the control function. This information should be automatically relayed to the a

22、ir traffic service unit.” And: “For a precision approach runway, the electrical circuits for the main power supply, lighting and control shall be so designed that the failure of one circuit shall not leave the pilot without visual guidance or shall result in a misleading pattern.” Different control

23、and monitoring systems of airfield lighting exist nowadays. This is why the need appeared to define their general characteristics or requirements in order to guarantee compatibility between systems. 1 Scope This prestandard specifies general requirements for control and monitoring system of aviation

24、 ground lighting installation. The purpose of this prestandard is to provide a set of requirements which are applicable to the control and monitoring system of aviation ground lighting installation. 2 Normative references This prestandard incorporates by dated or undated reference, provisions from o

25、ther publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this prestandard only when incorporated in it by amendment or rev

26、ision. For undated references the latest edition of the publication referred to applies.

27、ntion on International Civil Aviation, Volume1 and 2, Aerodrome Design and Operations (Issued by International Civil Aviation Organisation). 3 Definitions For the purposes of this prestandard the following definitions apply, as well as those given in ICAO Annex14. 3.1 ATC system Air Traffic Control

28、system is located in the control tower. It provides to the controllers information and help for control and monitoring airfield aerodrome lightings circuits, radionavigation circuits and others 3.2 visual aids system the visual aid system used for navigation consists of indicators and signalling dev

29、ices, markings, lights signs and markers on airfield 3.3 CCR CCR is the Constant Current Regulator. It is used to provide a constant current in aerodrome lighting circuits 3.4 RVR the Runway Visual Range is the range over which the pilot of an aircraft on the centerline of a runway can see the runwa

31、ds called “ILS and/or MLS” and visual aids intended for operations down to specific limit heights and limit RVR. Category I requires less equipment (visual and radionavigation aids) than Category IIIENV50230:1997 4 BSI 04-1999 4 General The control and monitoring system for the airfield lighting sys

32、tem should be considered as a part of the visual aids system, and consequently should be addressed like a component of the ATC system. Therefore design and workmanship of such a system should fulfil the high requirements for availability and fail safe operation. Besides keeping the controller worklo

33、ad in a reasonable level, the system should be a powerful tool for the organisation of preventive maintenance to increase the availability of the airfield lighting system. There should be a control and monitoring system: a) Suitable for every airport complexity and particular needs, and adaptable to

34、 changes in the airport physical characteristics (layout, installations, etc.) or in the airport procedures. It means a system designed on a modular basis. b) Having a conception inspired by safety, allowing for the redundancy of equipment or elements that prove crucial from a safety point of view.

35、c) With a high degree of reliability and availability. d) Capable of data exchange with related systems. These system descriptions contain only the functions and minimum requirements of a control and monitoring system independent from a particular hardware solution. The hardware design of a system s

36、hould follow the individual needs of an airport and should also be in accordance with the latest state of the technology. 5 Overview of the control and monitoring system Figure 1 shows an overview of the control and monitoring system with the peripherals and interfaces to the related systems. In the

37、 centre of this diagram the control and monitoring system is placed. Around this circle the operators, components and systems are arranged which are linked to the control and monitoring system. The arrows show the direction and also a short description of the data flow. Possible or necessary links b

38、etween the peripherals themselves or to other systems are not subject of this description and are not shown in the diagram. The peripherals for a basic system are: a) Human machine interface (HMI) for the controller. That could be the controller at the tower but also controller at the apron control

39、or other controller working positions at the airport, which are able and allowed to switch the airfield lighting system. The HMI provides also the certain relevant status information for the controller. b) HMI for the maintenance staff at the airport. c) Status protocol devices such a storage device

40、 and or protocol printer or other components that store the time and sequence of alarms and status informations. d) Interface to the CCRs and other control units (for example: sequence flash light control unit, circuit selector, contactor, etc.) but may include devices that only provide indications

41、(forexample: power generator, fuel level indications, etc.). Dependent on the configuration and requirements of an airport the control and monitoring system may provide the additional interfaces as an option: a) Interface for information interchange with airport systems such as aircraft docking syst

42、ems, building management systems or commercial systems. b) Interface to the ATC-system for command inputs (for example: actual CAT I, II, III information) and information output about the status of the airfield lighting system. c) Interfaces for additional monitoring devices for the supervision of t

43、he actual condition of the airfield lighting system components (for example: lamp operation monitoring, insulation measurement, hour meter, etc.). d) Interface for control signals from-field sensors. e) Interface to meteorological system to provide the runway visibility range (RVR). f) Interface to

44、a surface movement guidance and control system (SMGCS) for command inputs and information output about the status of the airfield lighting system.ENV50230:1997 BSI 04-1999 5 Figure 1 Overview diagram for the control and monitoring systemENV50230:1997 6 BSI 04-1999 6 Basic functions of a control and

45、monitoring system 6.1 Controller working places The controller working places are the main human machine interfaces (HMI) of the system to control the airfield lighting system and to display the actual operational status and alarms. The main objectives for the design for the HMI are to keep the cont

46、roller workload at a reasonable level and to allow the controller to select a command input and system to provide an accurate status output. To fulfil these requirements the functions of the HMI should provide only the functions and information that are necessary. All functions for maintenance and a

47、ll technical detail information should be directed directly to the maintenance working place. The number and the location of the working places are dependent on the configuration and requirements of the airport. Also the work share and hand over between different working places could be different. I

48、f there is more then one working place provided for the same lighting systems, the control and monitoring system should make sure that only one working place is active for command inputs at the same time. Every working place (active or inactive) should be capable of displaying the accurate status of

49、 the related airfield lighting systems. 6.1.1 Command input at the controller working places The basic requirements for input interfaces are: a) clear layout and sufficient dimensions to support simple and safe handling b) separate control elements for the ON, OFF and intensity setting for systems or groups of systems c) control elements for each runway to switch over the landing direction d) interface display test facility e) control element for alarm reset (to confirm new alarms and reset the audible signal) f) manual or automatic dimmer for the brightness o
