Research on Integration of Coal Mine Monitoring and Control System with Field Bus Control System Abstract:According to the construction of current coal mine monitoring and control systems in China，the paper proposes three kinds of applicable schemes of integrating PLC and DCS systems with field bus technology to digitize the system and to improve the flexibility and extent of the system.Essentially，the paper introduces the integration of FCS on I/O layers.Based on a real coal mine safety-monitoring and control system applied with a CAN field bus，the major technology of system relays and extensions is discussed.We believe that one of the most applicable methods is currently replacing the connection between function-stations and field-sensors with a CAN bus on I/O layers for system integration. Key words:monitor and control;field bus control system;CAN;integration 1 Coal Mine Monitoring and Control System and Field Bus Technology As one of the most important methods to improve modern management and production efficiency in coal mines，monitoring and control technology have been widely adopted to maintain safety in coal production.Taking advantage of foreign technologies from the 1980’s，coal mine monitoring and control systems have expanded rapidly in China.At present， automatic control has come into use in most large-scale coal mines，which greatly improved production efficiency and safety and lowered costs. In China，most sub-systems of coal mine systems work independently.They follow a DCS system structure of three layers(center layer，sub-station layer and sensor layer)which consists of a tree to-pology.They are composed of sensors，sub-stations on or under the ground，center stations，multiple controllers and display terminals(Fig.1).They work with analogue signals of 4–20 mA or 200–1000 Hz. Each coupled cable can only act as one line for transmission[1]. Currently control networks have been developed for digitalization and networking.Because traditional analogue signals of 4–20 mA or 200–1000 Hz can only carry simple measurement information and con-trol signals，the communication rate is restricted. Therefore，it is necessary to digitalize and network the entire monitoring and control system. Fig.1 Traditional Structure of Coal Mine Monitoring and Control System 展开

What's therole of the Supercapacitor? The supercapacitor resembles a regular capacitorwith the exception that it offers very high capacitance in a small package.Energy storage is by means of static charge rather than of an electro-chemicalprocess that is inherent to the battery. Applying a voltage differential on thepositive and negative plates charges the supercapacitor. This concept issimilar to an electrical charge that builds up when walking on a carpet. Thesupercapacitor concept has been around for a number of years. Newer designsallow higher capacities in a smaller size. Whereas a regular capacitor consists ofconductive foils and a dry separator， the supercapacitor crosses into batterytechnology by using special electrodes and some electrolyte. There are threetypes of electrode materials suitable for the supercapacitor. They are: highsurface area activated carbons， metal oxide and conducting polymers. The highsurface electrode material， also called Double Layer Capacitor (DLC)， is leastcostly to manufacture and is the most common. It stores the energy in thedouble layer formed near the carbon electrode surface. 展开

谁帮我翻译一下: LabVIEWTM(LaboratoryVirtualInstrumentEngineeringWorkbench)isapowerfulinstrumentationandanalysisprogramminglanguageforPCsrunningMicrosoftWindows，SunSPARCstations，AppleMaci... LabVIEWTM (Laboratory Virtual Instrument Engineering Workbench) is a powerful instrumentation and analysis programming language for PCs running Microsoft Windows， Sun SPARCstations， Apple Macintosh computers， Concurrent PowerMax， and HP-UX workstations. LabVIEW departs from the sequential nature of traditional programming languages and features a graphical programming environment and all the tools needed for data acquisition， analysis， and presentation. With this graphical programming language， called “G，” you can program in a block diagram notation， the natural design notation of scientists and engineers. After you create a block diagram program， LabVIEW compiles it into machine code. LabVIEW integrates data acquisition， analysis， and presentation in one system. For acquiring data and controlling instruments， LabVIEW supports RS-232/422， IEEE 488 (GPIB)， and VXI， including Virtual Instrument Software Architecture (VISA) functions， as well as plug-in data acquisition (DAQ) boards. An instrument library with drivers for hundreds of instruments simplifies instrument control applications. For analyzing data， the extensive Analysis library contains functions for signal generation， signal processing， filters， windows， statistics， regression， linear algebra， and array arithmetic. Because LabVIEW is graphical in nature， it is inherently a data presentation package. LabVIEW can generate charts， graphs， and customized， user-defined graphics. 尽量翻的好一点，谢谢能不能对GOOGLE自动翻译过的稍加修改下展开

Are the urban soils of Guangzhou polluted? In a review of heavy metal pollution of soils in china，chen et al.(1999) suggested that“Heavy-metal soil polltion is defined as the phenomena where the heavy-metal content in soils exceeds natural background levels and causes ecological destruction and deterioration of environmental quality” Table 6 compares the Guangzhou date with some background date and also some critical and trigger limits derived from the Netherlands and U.K. It can be seen from Table 6 that all top soil heavy metals，with the exception of Ni in the Park，are above the average value for Guangdong province. They also，again with the exception on Ni in the park，exceed the values for samples from Hainan Island，which affords a“clean”baseline data sea for the region. what is also of interest is that if the rations of heavy metal content for roadside sites in Guangzhou are compared to the Hainan data in from of a ratio then ratios of 3.09，1.04，4.16，1.84 and 1.59 are obtained for Cu，Ni，Zi，Pb and Cu respectively. With the exception of the 4.16 for Zn they are not dissimilar to rations of roadside to park top soil reported previously for Guangzhou. This suggests that the roadside to park comparison for soils in Guangzhou may pick up enhancement of heavy metals associated with vehicular traffic. 展开

During the preparation of the nano-products， these nano-units， such as nanoparticles， nanoclusters， nanowires and nanorods， can also self-assemble into the novel structural aggregates by several routes， including electron irradiation deposition [19]， chemical vapor deposition [20]， laser vaporization-condensation [21]， charge transferring [22]， an organic reagent-assisted method [23]， solution-liquid-solid method [24] and catalytic vapor-liquid-solid growth [25]. With these routes， various nanoscale or microscale aggregates can demonstrate novel architectures， including tree-like， web-like， spherical， nanowire-like， network and fishbone-like aggregates. As a well-known method for producing the nanocapsules， however， arc-discharge has been rarely used to synthesize the aggregates self-assembled by the nanocapsules prepared simultaneously in arc-discharge. Nevertheless， it is possible that the arc-discharge can be developed into a new way to synthesize the aggregates. In the present work， we utilized arc-discharge technique with modified strategies， involving changing the hydrogen pressure， introducing gadolinium - aluminum alloy ingot as the anode and adjusting the elements percent of the anode according to their evaporation pressure， to synthesize a new type of nanocapsules， with intermetallic compound GdAl2 as core and amorphous Al2O3 as shell， which enlarge the family of the magnetic nanocapsules. At the same time， the regularly aligned three-dimensional macro-aggregates self-assembled by the nanocapsules without any template and catalyst were simultaneously synthesized in arc-discharge process. 展开
