The thesis regards solving RS232 interface equipment and PROFIBUS-DP interconnection as the direction of studying. Designing and developing has RS232 interface and PROFIBUS-DP interface Slave. Realize the protocol converted between RS232 equipment and PROFIBUS-DP .
The embedded OS VxWorks installed in this equipment, which is used to control the external interface equipments was recognized by NASA, let the equipment liberated from the heavy management of outside equipments' control, specialized for the information processing and data exchange, thus greatly increases the efficiency of communication interface equipment.
Virtual reality technology(VRT) is one which can produce a interchangeable,threedimensional environment system aided by computer graphics system,interface equipments to display and control synthetically.
This text gives a nuclear instrument device with USB interface,which regard ARM2220 of core as an example,introduces the designing process of any external device with USB interface regarded as HID(Human Interface Device) by the host computer in detail and the design method of the application software,discusses how to realize the no drive design of any instrument in the mode of CPU+USB interface chip.
The objectives of the specifications are described,both network instrument protocol and the LAN-to-VXI mapping are given to be implemented within TCP/IP-VXIbus interface devices,a brief LAN primer is given to assist in understanding the technology.
In this paper,several solutions for data acquisition based on virtual instrument are put forward in which the interface devices and major technology standards such as serial port,GPIB,VXI,PXI,DAQ board are involved.
Interface device which displays the propagation of motor unit action potentials on a television screen
The SPIDAR-G (SPace Interface Device for Artificial Reality with Grip) allows users to interact with virtual objects naturally by manipulating two hemispherical grips located in the centre of a device frame.
Normal components (Bz) of MCG were measured at rest with a multi-channel superconducting quantum interface device (SQUID) system, and differentiated in the tangential direction to obtain current vector maps.
The force feedback joystick, a human interface device is an input-output device.
The model of the VR system is built based on a haptic interface device behavior that enables the operator to feel the actual force feedback from the virtual environment just as s/he would from the real environment.
