KM3NeT Acquisition Control: advanced techniques and best practices in data acquisition software development

The Control Unit of the KM3NeT Data Acquisition is the software suite that is responsible for operating all the components of the KM3NeT telescopes in a coordinated and scientifically proficient way. It controls a wide span of parameters and procedures, from the power supplies, to the operating voltages of more than 64000 photomultipliers in each detector block, to the setup of the various trigger algorithms that are applied online. The same software suite is also designed to be used in all test and qualification benches, from single Digital Optical Modules to full Detection Units. As the KM3NeT detectors are being incrementally built, the Control Unit is employed in a variety of setups and configurations, and is a dynamic software project, still adapting to shifting needs.The conflicting requirements of flexibility and stability are reconciled by proper code development policies. The Control Unit is able to cope with dynamically changing scenarios of multiple firmware generations coexisting in the same detector, for various reasons including hardware compatibility as well as testing purposes. The code also allows for static verification and extensive unit tests.A Central Logic Board Simulator software was also developed to help testing the whole architecture. Such a simulator provides properly faked slow control parameters, features a fully specification-compliant state machine and can generate fake data with specific profiles to feed the Trigger and Data Acquisition System. In this way, offline integration tests can be executed at each new software release, ensuring their smooth deployment to production sites and minimising chances of mistakes by operators.

Raspberry Pi as a low-cost data acquisition system for human powered vehicles

Abstract The presented work was conducted to test the hypothesis that a Raspberry Pi Model B single board computer can be applied as a riding dynamics data acquisition system for use on human powered vehicles. The research of the subject was followed by the development, which led to a working prototype of such a data acquisition system. The procedure included the system component integration, system software setup and data acquisition software development. The prototype system was tested in laboratory conditions, and in the field using a bicycle as the test vehicle. The results prove the initial hypothesis and confirm that the performance of the developed system is comparable to some higher-priced and less portable data acquisition systems. Other possibilities of application of the developed system and intended future improvements are discussed in the final part of the paper.

Study on the Development Platform of Codeless Data Acquisition Software

In this paper, a codeless data acquisition software development platform (CDASDP), which is written by LabWindows/CVI, is described. This software, based on the idea of software reusing, is a visual codeless programming system with built in support for databases, 2D drawings, ActiveX, etc. Users can develop personalized software by themselves and need not learning or using textural computer languages. Complex programming logic can be simplified into 3 steps such as parameters configuration, user-interface edition, and software creation. By use of CDASDP, development cycle and cost of professional measurement software (PMS) is reduced substantially.

Progress on the Data Acquisition System at NSCL

We report on the progress made in data acquisition software development. Specifically, a unique generalized data routing scheme has been developed which allows user online analysis programs to be safely integrated into the acquisition system without endangering data sent to event recording devices. We describe the structure of the system. Performance is discussed and throughput calculated from it. User experience with the system is also discussed. We show how this routing system may easily be adapted to loosely coupled multiprocessor systems.

A Higher Level Language Data Acquisition System (II) - The Development System

The nuclear physics group at the University of Illinois has implemented a data acquisition system using modified versions of the Concurrent Pascal and Sequential Pascal languages. An operating system has been written to support the development of data acquisition software. This paper concentrates on providing practical information of the architecture and characteristics of the system, rather than on performance evaluation or system design strategy.
