(Amendment)Maritime navigation and radiocommunication equipment and systems - Digital interfaces -- Part 3: Serial data instrument network
Maritime navigation and radiocommunication equipment and systems - Digital interfaces -- Part 3: Serial data instrument network
This part of IEC 61162 is based upon the NMEA 2000 standard. The NMEA 2000 standard contains the requirements for the minimum implementation of a serial-data communications network to interconnect marine electronic equipment onboard vessels. Equipment designed to this standard will have the ability to share data, including commands and status, with other compatible equipment over a single signalling channel. Data messages are transmitted as a series of data frames, each with robust error check confirmed frame delivery and guaranteed latency times. As the actual data content of a data frame is at best 50 % of the transmitted bits, this standard is primarily intended to support relatively brief data messages, which may be periodic, transmitted as needed, or on-demand by use of query commands. Typical data includes discrete parameters such as position latitude and longitude, GPS status values, steering commands to autopilots, finite parameter lists such as waypoints, and moderately sized blocks of data such as electronic chart database updates. This standard is not necessarily intended to support high-bandwidth applications such as radar, electronic chart or other video data, or other intensive database or file transfer applications. This standard defines all of the pertinent layers of the International Standards Organisation Open Systems Interconnect (ISO/OSI) model, from the application layer to the physical layer, necessary to implement the required IEC 61162-3 network functionality. This standard defines data formats, network protocol, and the minimum physical layer necessary for devices to interface. SOLAS applications shall employ redundant designs (for instance dual networks, redundant network interface circuits) to reduce the impact of single point failures. The NMEA 2000 standard provides the fundamental tools and methods to support redundant equipment, buses and messaging. Specific shipboard installation designs are beyond the scope of this standard, however some guidance is given in Annex A.

Pomorska navigacijska in radiokomunikacijska oprema in sistemi - Digitalni vmesniki - 3. del: Instrumentno omrežje s serijskimi podatki - Dopolnilo A2 (IEC 61162-3:2008/A2:2014)
Ta del IEC 61162 je osnovan na standardu NMEA 2000. Standard NMEA 2000 vsebuje zahteve za minimalno vgraditev komunikacijskega omrežja z serijskimi podatki, za medsebojno povezavo pomorske elektronske opreme na plovilih. Oprema, načrtovana s tem standardom, bo imela možnost delitve podatkov, vključno z ukazi in statusom, z drugo združljivo opremo skozi enojni signalni kanal. Podatkovna sporočila so oddajana kot serija podatkovnih okvirjev, vsak z časom dobave okvirja z potrjenim robustnim pregledom za napake in časom zagotovljene zakasnitve. Ker je dejanska vsebnost podatkovnega okvirja v najboljšem primeru 50 % oddajanih bitov, je ta standard primarno namenjen za podporo relativno kratkim podatkovnim sporočilom, ki so lahko periodična, oddajana po potrebi ali za uporabo na zahtevo poizvedbe ukazov. Običajno podatki vsebujejo diskretne parametre, kot so položaj geografske širine in dolžine, GPS statusne vrednosti, ukaze krmiljenja do avtopilotov, sezname končnih parametrov kot so smerne točke, in zmerno velike podatkovne bloke kot so nadgradnje baz elektronskih grafov. Ta standard ni nujno namenjen za podporo uporab z visoko pasovno širino, kot so radar, elektronski grafi ali drugi video podatki ali druge intenzivne uporabe baz ali prenosa podatkov. Ta standard določa vse bistvene plasti modela odprtih sistemov medsebojne povezave mednarodnih standardizacijskih ustanov (ISO/OSI), iz plasti uporabe do fizične plasti, potrebne za vpeljavo zahtevanih IEC 61162-3 omrežnih funkcionalnosti. Ta standard določa podatkovne formate, omrežni protokol in minimalno fizično plast potrebno za priključitev naprav. SOLAS uporabe naj uporabijo redundantne načrte (na primer dvojna omrežja, redundantna omrežna vmesna vezja) za zmanjševanje posledic lokalnih odpovedi. Standard NMEA 2000 zagotavlja osnovna temeljna orodja in metode za podporo redundantne opreme, vmesnikov in obveščanja. Določeni načrti vgradnje na ladjah so zunaj področja uporabe tega standarda, čeprav je nekaj napotkov podanih v Dodatku A.

The SIST EN 61162-3:2008/A2:2014 standard provides a comprehensive framework for maritime navigation and radiocommunication equipment, specifically focusing on the digital interfaces necessary for a serial data instrument network. This standard extends the principles outlined in the NMEA 2000 standard, emphasizing a robust protocol for interconnecting marine electronic systems aboard vessels. The scope of this standard is particularly significant as it ensures that equipment can efficiently share critical data such as position, GPS statuses, and other navigational commands over a singular signaling channel. The specification of robust error checking and guaranteed latency times within data frame transmission enhances the reliability of communications in maritime systems. This is vital for applications where precision and timely data are paramount for safe navigation. One of the key strengths of the SIST EN 61162-3 is its detailed outlining of the ISO/OSI model layers, from the application layer to the physical layer, which are essential for implementing the network functionality required for effective communication between devices. The inclusion of data formats and network protocols supports manufacturers in developing compatible equipment that adheres to established standards, thereby streamlining the integration of new technology within existing systems. Furthermore, the provision of guidelines for redundancy in shipboard applications is an important aspect of this standard. By encouraging designs that incorporate dual networks and redundant circuits, it mitigates the risks associated with single points of failure, which is crucial in maintaining operational safety at sea. While the standard does not encompass high-bandwidth applications or extensive data transfer, it remains relevant for its targeted focus on essential communication needs in marine environments. The emphasis on timely, brief data messages ensures that standardization meets the operational demands of contemporary maritime navigation. Overall, SIST EN 61162-3:2008/A2:2014 stands out for its clarity in defining the necessary components for establishing effective digital interfaces in maritime navigation, making it an indispensable reference for equipment manufacturers and marine operators looking to improve their communication infrastructures.
Die Norm SIST EN 61162-3:2008/A2:2014 behandelt die maritimen Navigations- und Funkkommunikationsgeräte sowie -systeme und konzentriert sich auf digitale Schnittstellen, insbesondere Teil 3, der das serielle Datengerätenetzwerk definiert. Diese Norm basiert auf dem NMEA 2000 Standard, der die Anforderungen für die Mindestimplementierung eines seriellen Kommunikationsnetzwerks zur Vernetzung maritimer elektronischer Geräte an Bord von Schiffen festlegt. Ein wesentlicher Stärke dieser Norm liegt in ihrer Fähigkeit, eine effiziente Datenkommunikation zwischen Geräten zu ermöglichen, da sie den Austausch von Informationen, einschließlich Befehlen und Status, über einen einzigen Signalisierungskanal bereitstellt. Die Struktur der Datenübertragung in Form von robusten Datenrahmen garantiert eine fehlerfreie Übermittlung und garantiert Latenzzeiten, was die Norm besonders relevant für Anwendungen macht, die schnelle und zuverlässige Datenübertragungen erfordern, wie beispielsweise die Übertragung von Positionsdaten oder Navigationskommandos an Autopiloten. Ein weiterer wichtiger Aspekt der SIST EN 61162-3:2008/A2:2014 ist die Tatsache, dass sie nicht nur die erforderlichen Schichten des ISO/OSI-Referenzmodells definiert, sondern auch die minimalen physikalischen Anforderungen für die Schnittstelle zwischen Geräten festlegt. Dies ermöglicht eine klare und einheitliche Umsetzung der erforderlichen Netzwerkfunktionen, die für maritime Anwendungen unerlässlich sind. Durch die Standardisierung der Datenformate und Netzwerkprotokolle wird eine Interoperabilität zwischen unterschiedlichen Geräten sichergestellt, was die Integration von neuem Equipment an Bord vereinfacht. Zusätzlich wird in dieser Norm auch auf Redundanz eingegangen, was für SOLAS-Anwendungen von Bedeutung ist. Die Empfehlungen zur Implementierung redundanter Designs, etwa durch doppelte Netzwerke oder redundante Schnittstellenschaltungen, tragen wesentlich dazu bei, das Risiko von Ausfällen zu minimieren und die Sicherheit an Bord zu erhöhen. Trotz ihrer umfassenden Abdeckung sind spezifische Installationsrichtlinien für Schiffe nicht Teil dieser Norm, jedoch wird nützliche Anleitung in Anhang A bereitgestellt, was den Anwendern hilft, die Norm effektiv in die Praxis umzusetzen. Insgesamt ist die SIST EN 61162-3:2008/A2:2014 eine unverzichtbare Norm, die die Grundlage für die Entwicklung und den Einsatz von digitalen Schnittstellen in maritimen Anwendungen legt und sowohl die Effizienz als auch die Sicherheit der Datenkommunikation an Bord von Schiffen gewährleistet.

SIST EN 61162-3:2008/A2:2014 표준은 해양 내비게이션 및 무선통신 장비와 시스템을 위한 디지털 인터페이스 분야에서 중요한 역할을 수행하는 문서입니다. 이 표준은 NMEA 2000 표준을 기반으로 하여 선박 내 해양 전자 장비 간의 직렬 데이터 통신 네트워크를 구성하는 최소 요구사항을 명시하고 있습니다. 이 표준의 강점 중 하나는 단일 신호 채널을 통해 호환 가능한 장비들과 데이터, 명령 및 상태를 공유할 수 있는 기능을 제공한다는 점입니다. 데이터 메시지는 일련의 데이터 프레임으로 전송되며, 각 프레임은 강력한 오류 검사를 통해 전송의 신뢰성을 보장합니다. 또한, 보장된 지연 시간 덕분에 실시간 데이터 통신이 가능하여, 해양 환경에서의 효율성을 크게 향상시킵니다. SIST EN 61162-3 표준은 다양한 해양 데이터의 전송을 지원하도록 설계되었으며, 기본적으로 단순한 데이터 메시지에 적합합니다. 예를 들어, 위치(위도 및 경도), GPS 상태, 자율 조타 장치에 대한 조타 명령과 같은 데이터가 포함됩니다. 이는 고대역폭 애플리케이션(예: 레이더, 전자 해도 등)을 지원하기 위한 것이 아니라, 주기적이거나 필요한 시점에 송신되는 데이터에 최적화되어 있습니다. 또한, 이 표준은 IEC 61162-3 네트워크 기능을 구현하는 데 필요한 ISO/OSI 모델의 모든 관련 계층을 정의합니다. 애플리케이션 계층에서 물리 계층에 이르기까지 다양한 계층의 요구사항이 명확히 규정되어 있어, 데이터 포맷, 네트워크 프로토콜, 및 장치간 인터페이스를 위한 최소 물리적 레이어가 포함되어 있습니다. 마지막으로, SOLAS 애플리케이션은 단일 지점 실패로 인한 영향을 줄이기 위해 이중 네트워크 및 중복 네트워크 인터페이스 회로와 같은 중복 설계를 채택해야 합니다. NMEA 2000 표준은 이러한 중복 장비 및 메시지를 지원하는 중요한 도구와 방법을 제공합니다. 크고 복잡한 선박 설치 설계에 대한 세부 사항은 이 표준의 범위를 넘어서는 부분이지만, 부록 A에서 일부 가이드를 제공하여 사용자에게 유용한 정보를 제공합니다. 따라서, SIST EN 61162-3:2008/A2:2014 표준은 해양 전자 통신의 신뢰성을 높이고, 호환성을 보장하며, 필요한 데이터 전송을 위한 효율적인 기반을 제공하는 매우 중요한 문서입니다.
La norme SIST EN 61162-3:2008/A2:2014 joue un rôle crucial dans le domaine de la navigation maritime et des équipements de radiocommunication. Elle s'inscrit dans le cadre des normes NMEA 2000, établissant des exigences claires pour la mise en œuvre d’un réseau de communications par données série, conçu pour interconnecter l'équipement électronique maritime à bord des navires. Un des points forts de cette norme est sa capacité à faciliter le partage de données entre des équipements compatibles via un seul canal de signalisation. Cela permet une communication efficace des données, des commandes et des statuts entre les différents systèmes embarqués. Les messages de données sont transmis sous forme de trames, garantissant une livraison fiable avec des vérifications d’erreur robustes et des temps de latence assurés, ce qui est primordial pour le bon fonctionnement des opérations maritimes. La norme se distingue également par son approche en matière de gestion des données; elle se concentre principalement sur des messages de données relativement brefs, tels que les paramètres discrets de position GPS, les valeurs d’état GPS, et les commandes de direction pour les pilotes automatiques. Cette spécificité en fait un outil adapté aux besoins des utilisateurs d'équipements marins, sans viser les applications à large bande, telles que le radar ou les transferts de fichiers lourds. En outre, le fait que la norme couvre les différentes couches du modèle ISO/OSI, de la couche application à la couche physique, est un atout majeur car il fournit une base solide pour la mise en place d'une fonctionnalité réseau conforme à la norme IEC 61162-3. Cela inclut des définitions précises des formats de données, des protocoles réseau et des exigences minimales pour la couche physique, essentielles pour garantir l’interopérabilité entre divers appareils. Enfin, la norme impose également des conceptions redondantes pour les applications SOLAS, permettant ainsi de diminuer l'impact des pannes uniques, un aspect essentiel dans le cadre des opérations maritimes critiques. Bien que certaines conceptions d'installation spécifiques à bord dépassent le champ de cette norme, des orientations sont fournies dans l'Annexe A, ce qui renforce sa pertinence en tant que référence standardisée pour les utilisateurs de l'équipement maritime. En somme, la SIST EN 61162-3:2008/A2:2014 est une norme essentielle qui assure l'interconnectivité, la fiabilité, et la sécurité des communications des systèmes de navigation maritime, tout en étant adaptée aux exigences spécifiques d'un équipement électronique maritime.
