Using embedded systems for the remote delivery and recovery of National Ignition Facility and optical line replaceable units

PDF Version Also Available for Download.

Description

This paper describes the design and development of the embedded control systems used to deliver and recover the National Ignition Facility (NIF) optical line replaceable units (LRUs). As part of the NIF Operations Special Equipment Control System (OSECS), the embedded control systems form a part of the front end processor (FEP) layer of the OSECS. During the start-up and operations phases of the NIF project, it is anticipated that a significant number of LRUs will be delivered to the laser beamline structure. The frequency of LRU delivery combined with the design of the facility pose severe constraints for human-only delivery ... continued below

Description

This paper describes the design and development of the embedded control systems used to deliver and recover the National Ignition Facility (NIF) optical line replaceable units (LRUs). As part of the NIF Operations Special Equipment Control System (OSECS), the embedded control systems form a part of the front end processor (FEP) layer of the OSECS. During the start-up and operations phases of the NIF project, it is anticipated that a significant number of LRUs will be delivered to the laser beamline structure. The frequency of LRU delivery combined with the design of the facility pose severe constraints for human-only delivery and recovery operations. To reduce the risks to personnel and to allow for safe and efficient delivery of equipment, LLNL engineers are designing and developing embedded control systems for the low-level device control of NIF Transport and Handling mechanical delivery system components. The design of the embedded control system makes use of advanced PC-based motion control technology commonly found in industrial applications. The PC-based platform consists of commercial-off-the-shelf (COTS) hardware and software such as industrial computers, motion controllers, data acquisition boards, sensors technology, networking capabilities, development languages and operating system. Wireless networking technology is also being employed in the design to achieve a distributed control architecture for operator mobility during operations. Additionally, the PC-based platform provides the greatest degree of flexibility in satisfying a diverse set of motion control requirements and helps to maintain low maintenance and future upgrade costs.
