Power systems for data-processing and communication equipment used in mission-critical applications that require high system availability must be implemented with fault-tolerant architectures. Generally, these fault-tolerant power architectures require that the power supplies built into data-processing/communication equipment are capable of operating from two different ac power sources. In this...

Modeling for operation rules is essential function requirement in equipment simulation training system based on VR. Aiming at the modeling actuality of present equipment operation rules, which has no systematic, no generality and no formatting expression, layered modeling system framework based on federation is brought forward referencing to the “Federation and Member” concept of HLA. Open mode...

Strong atmospheric turbulence (disturbance due to rain, fog, haze etc.) is a major problem in optical communication system. In this paper, the performance analysis of an optical communication system with Free Space Optics (FSO), Optical Wireless Communication (OWC) and Single Mode Fiber (SMF) in weak atmospheric turbulence has been analysed. Data stream is transmitted at 20Gbps using different ...

Due to the proliferation of broadband services in recent years, the volume of information transmitted across the Internet is growing steadily. As a result, data processing capacity of information processing systems are expected to significantly increase. Signal processing in an information processing system can be classified as between equipment, between boards inside the equipment, and between...

The data acquisition equipment is very useful and popular equipment in agriculture and the other fields. This paper introduces the design of a portable data acquisition and communication system used in cropland. It collect signals of various analog and digital sensors, GPS space and time data, saving data by USB interface and transmission through WCDMA or Bluetooth. The key technology of the sy...
