IEC 62940 pdf download.Maritime navigation and radiocommunication equipment and systems – Integrated communication system (ICS)
1 Scope
IEC 62940 specifies the minimum operational and performance requirements, technical characteristics and methods of testing, and required test results, for shipborne integrated communication systems (ICS) designed to perform ship external communication and distress and safety communications (GMDSS) and the functions of onboard routeing of this communication. It takes account of IMO Resolution A.694(1 7) and is associated with IEC 60945. When a requirement in this document is different from IEC 60945, the requirement in this document takes precedence.
3 Terms, definitions and abbreviations
3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1.1 COM-HMI communications human machine interface human machine interface for presentation and handling of communication tasks on the bridge 3.1 .2 CCRS consistent common reference system sub-system or function of an INS for acquisition, processing, storage, surveillance and distribution of data and information providing identical and obligatory reference to sub- systems and subsequent functions within an INS and to other connected equipment, if available 3.1 .3 ICS integrated communication system composite communication system designed to perform ship external communication and distress and safety communications and the functions of onboard routeing of this communication 3.1 .4 radio communication wireless transmission of information Note 1 to entry: Examples of radio communication are voice radio communication and the wireless exchange of data. 3.1.5 remote COM-HMI remote communications human machine interface human machine interface for presentation and handling of communication tasks, placed outside the ICS 3.1.6 subsystem communication-related device within the ICS
4 General and operational requirements
4.1 General requirements 4.1.1 Requirements The ICS shall meet the general requirements set out in IMO Resolution A.694(1 7) as further specified in IEC 60945 appropriate to their category, for example “protected”. However, specific requirements may be made in individual equipment standards so consideration should be given to any exemptions or additional requirements in combination with standards for all included radiocommunications equipment in the ICS. The manufacturer shall declare any preconditioning required before environmental checks. For the purposes of this document, the following definitions for “performance check” and “performance test”, required by IEC 60945, shall apply: Performance check Reconfigure the EUT and check by non-quantitative visual checks that the system is still operative. Performance test Identical to the “performance check”. The manufacturer shall declare the equipment to be tested and the tasks and functions that it performs. The EUT shall be installed in compliance with the manufacturer´s installation manual. Where equipment is divided, the entire configuration shall be tested together. The manufacturer shall declare • the physical parts involved, • the location of tasks and functions, • the general data flow between physical and/or logical parts, and • the dependencies between tasks and functions. NOTE Typical examples are hardware overviews down to the lowest replaceable unit, block diagrams or high functional level software descriptions. The acoustic alarm level may be capable of being adjustable below the level defined in IEC 60945. The ICS shall meet the requirements for the presentation of information on shipborne displays set out in IMO Resolution MSC.1 91 (79) as further specified in IEC 62288:201 4, Clause 4 and Clause 7.The ICS shall meet the requirements for alert management as an alert source (see Clause 6 and Clause 7). 4.1.2 Methods of testing and required test results Verify conformance with IMO Resolution A.694(1 7) by testing in accordance with IEC 60945. Verify conformance with IMO Resolution MSC.1 91 (79) by testing in accordance with IEC 62288:201 4, Clause 4 and Clause 7. 4.2 Test site Unless otherwise stated, all tests in this document are to be executed in a laboratory environment with a simulator arrangement or via live “on-air” tests on the actual equipment. For a simulator arrangement, the following characteristics are required: • capable of simulating the “air-interface” for transmission of radio signals for the equipment included in the ICS; • capable of simulating AIS targets and other AIS messages. The simulated signals shall be in accordance with the applicable international standards. The output signals shall comply with IEC 61 1 62-1 and with the types of interfaces supported by the EUT according to the manufacturer´s declaration.
