Design of Data Transfer in Intelligent Building System

The energy conservation system of intelligent building in wireless sensor network could dynamically control the devices of building in order to that energy conservation,such as the light,condition air and so on.The reliable transmission of control information is vital for the stable operation of this energy conservation system. The paper introduced a kind of measurement and control terminal methods based on ZigBee network.The design of hardware and software were mainly discussed.The design of hardware , sensor ,USB interface and software in intelligent building control terminal were discussed in details based on the CC2531 chip. Finally the design was used in the intelligent building research.The timely and reliable transmission of the control information can be realized.

The LVD experiment data acquisition system

Data acquisition for the LVD, a massive underground neutrino/muon detector containing 1800 tons of liquid scintillator in 1520 separate tanks and approximately 20000 (8-wire) Iarocci-type streamer chamber assemblies, is discussed. The detector is designed to look for stellar collapse neutrinos as well as for a broad range of physics experiments including searches for muon point sources, neutrino oscillations, and supersymmetric decay modes of the proton. The data acquisition challenge comes from the large physical size (49 m*12 m*13 m) and the large number of individual detectors involved. Data rates will be low enough to allow the use of CAMAC for the front-end hardware. However, peak data transfer design requirements for worst-case stellar collapse scenarios, along with the constant overhead of detector status monitoring, dictates the use of dedicated front-end processors (CES-STARBURST). The physical size of the detector system further suggests the use of a distributed data acquisition computer environment (VAXCluster). The CERN-developed MODEL online data acquisition system has been selected for the basic software architecture. The detector design and data acquisition hardware and software are described. >
