The development of the Waterloo Flexible Link Experimental (WATFLEX) facility was initiated at the University of Waterloo to provide resources for conducting experiments involving the dynamics and control of flexible robotic manipulators – specifically, two dimensional dynamic mass capture, impact dynamics and vibration suppression. The system consists of a number of different subsystems including the robotic manipulator, motion and deflection sensors, the digital controller, the data acquisition system, and the pneumatic system that floats the manipulator on a support structure. In this paper, the design and current status of each of these subsystems is described. Experimental analysis results of the support table, the data acquisition system, and some analog sensors are presented and analyzed.

A new material testing reactor Jules Horowitz Reactor is under construction at CEA Cadarache. The materials to be irradiated will be placed into experimental devices around the reactor. Process and measurements of experimental devices will be carried out by command control. A data acquisition system having processing performances will be associated to the programmable logic controller. The challenge is to design and realize for twenty experiment devices a high availability data acquisition system architecture for 50 years of sustainability. The real time target will achieve 24/7 data acquisition and real time processing. This scalable architecture could be use as well for JHR experimental devices with high availability as for testbed. This architecture could be run on a standalone station for a measuring bench or deployed on cluster for high availability. CAREDAS’s design is modular and use proven widely used open source solutions. All parts are independent from each other and can be replaced with another technology with the same functionalities. This ensures sustainability and control of software sources.

In the present IT age, we are in need of fully automated industrial system. To design of Data Acquisition System (DAS) and its control is a challenging part of any measurement, automation and control system applications. Advancement in technology is very well reflected and supported by changes in measurement and control instrumentation. To move to highspeed serial from Parallel bus architectures has become prevalent and among these Ethernet is the most preferred switched Serial bus, which is forward-looking and backwardcompatible. Great stride have been made in promoting Ethernet use for industrial networks and factory automation. The Web based distributed measurement and control is slowly replacing parallel architectures due to its non-crate architecture which reduces complexities of cooling, maintenance etc. for slow speed field processing. A new kind of expandable, distributed large I/O data acquisition system based on low cost microcontroller based electronic web server[1] boards has been investigated and developed in this paper, whose hardware boards use 8-bit RISC processor with Ethernet controller, and software platform use AVR-GCC for firmware and Python for OS independent man machine interface. This system can measure all kinds of electrical and thermal parameters such as voltage, current, thermocouple, RTD, and so on. The measured data can be displayed on web pages at different geographical locations, and at the same time can be transmitted through RJ-45 Ethernet network to remote DAS or DCS monitoring system by using HTTP protocol. A central embedded single board computer (SBC) can act as a central CPU to communicate between web servers automatically.

Engine running plays very important roles in a turbo-shaft engine production and maintenance. Traditional computer aided testing is just work as a data acquisition system to measure parameters and control some devices. In this paper, a CAT system is realized based on VXI and virtual instrument technology, which also communicate with the PLC, the ECU and the dynamometer, to provide a centralized information system for a turbo-shaft engine running. Multi-functions are realized to assistant users before, during and after experiments.

Real time data acquisition system has been paid wild attention to due to exponentially expanding industrial control and measurement. Of many industrial bus, PCI (peripheral component interconnect) bus is a very useful communication protocol available for off-the-shelf PC and high speed acquisition. In the document, an implementation solution of data real-time acquisition based on PCI bus is described. The data acquisition system mainly consists of signal regulation circuit, AD conversion, LVDS transmission, PCI controller. XC3S700 of XILINX FPGA was used as the core chip to bridge and control all parts, which has rich internal resource. Driving program of PCI bus was designed by VC in industrial computer. Test results show that the system can collect multi-channel signal concurrently, steadily and in real time, and has some application value.
