SENSORS: Ocean Observing System Instrument Network Infrastructure

P.I. Edgington（MBARI）提案编号：0330428提案标题：传感器：在本提案中，PI解决了传感器与海洋观测站接口的关键技术问题，以a）减少准备、部署和支持仪器所需的劳动力，B）确保实时和存档数据可用，c）使观测站仪器的开发更容易，以及d）为支持并非为观测站专门开发的仪器提供途径。如果共同体采用这一办法，将使不同海洋观测系统之间的仪器具有互操作性。这里提出的测试计划，以及其他机构的仪器制造商和观测台开发人员的参与，旨在确保仪器基础设施的开发能够满足社区需求，并广泛提供结果。为了实现这一发展，PI正在应用分布式对象、智能网络、即插即用和XML技术来创建一个统一的软件基础设施，以支持基于系泊的深海观测系统的开发、部署和操作，其目标是简化网络观测系统中的配置、接口和控制仪器的问题，这些系统可能具有间歇性和有限的带宽，以及简化对来自这些系统的数据的访问和管理。一旦完成，原型将在火星（蒙特雷加速研究系统）天文台进行测试。 这一建议的发展背后的理由是，有一个迫切需要开发一个统一的基础设施，配置，接口和控制仪器，以及管理数据的仪器部署在分布式网络传感器系统。这一建议针对三个问题：1）需要开发标准仪器接口协议和仪器适配器，其将简化海上配置的便利性，以及系统中的自动化设备和服务发现，2）开发用于使用XML技术描述仪器元数据的标准方法，以及用于将传感器数据沿着其元数据递送到海岸的手段，以及3）使用分布式对象、客户机-服务器技术的统一应用编程接口（API），其通过使网络层对应用开发者透明来简化控制和访问仪器的任务。

P.I. Edgington (MBARI) Proposal #: 0330428Proposal Title: SENSORS: Ocean Observing System Instrument Network InfrastructureProject Summary In this proposal the PI addresses the key technology issue of interfacing sensors with ocean observatories to a) decrease labor required for preparing, deploying and supporting instruments, b) ensure real-time and archived data is usable, c) make developing instruments for observatories easier, and d) provide pathways for the support of instruments not purpose- developed for observatories. If adopted by the community, this approach would allow interoperability of instruments between different ocean observatory systems. The testing program proposed here, and the involvement of instrument manufacturers and observatory developers at other institutions, is structured to ensure that development of the instrument infrastructure is responsive to community needs and the results made widely available. For this development, the PI is applying distributed object, smart network, plug-and-work, and XML technologies to create a uniform software infrastructure to support the development, deployment, and operation of mooring based, deep ocean observing systems with the goal of simplifying the problems of configuring, interfacing, and controlling instruments in networked observing systems with potentially intermittent and limited bandwidth, as well as simplifying access to, and management of, the data coming from such systems. Once completed, the prototype will be tested at the MARS (Monterey Accelerated Research System) observatory. The rationale behind this proposed development is that there is a pressing need to develop a uniform infrastructure to configure, interface, and control instruments as well as manage data from the instruments deployed in distributed networked sensor systems. This proposal addresses three problems: 1) the need to develop a standard instrument interface protocol and instrument adaptor that will simplify ease of configuration at sea, as well as automated device and service discovery in the system, 2) development of a standard methodology for describing instrument metadata, using XML technology, and a means for delivering sensor data, along with its metadata, to shore, and 3) a uniform application programming interface (API) using distributed object, client-server technology, that will simplify the task of controlling and accessing instruments by making the network layer transparent to the application developer.
