【正文】 er operating the puter, like manipulating a especially conventional electronic devices designed theirs. The essence of virtual instrument technology is that hardware softwarized technology, take full advantage of the latest puter technology to implement and expand the functions of traditional instruments. LabVIEW (laboratory virtual instrument engineering workbench) is a graphical programming and development environment, also known as G language. It is widely used by industry, academia and research laboratories, accepted as the standard data acquisition and instrument control software. LabVIEW not only provides and plies with all the functions of hardware and data acquisition cards munications of GPIB, VXI, RS232 and RS485 protocol, and builtin library functions support for TCP / IP, ActiveX and other software standards. The software for scientists and engineers is a programming language, it provides a simple, intuitive graphical programming mode, saves a lot of development time, has plete function, best embodied style of virtual instrument. In response to these circumstances, developed a mine hoist Integrate Performance Monitoring System based on virtual instrument LabVIEWbased. Show in Figure 3. With signal conditioning and data acquisition card to receive signals from sensors, then sent the received signal to the virtual instrument software platform, enables the following features: （ 1） show speed, acceleration, braking time, displacement, oil pressure, delay time and other relevant parameters in digital, and display speed, acceleration, traction, displacement and hydraulic curves. （ 2） Dynamically monitor the hydraulic oil pressure and oil pump running station, based on these parameters to avoid important braking system failure. （ 3） Test brake air travel time, relay delay time and other time parameters. （ 4） inquiry to the measured curve and hoist parameters。 PLC。英文原文 Study of Inherent Safety Mine hoist based on modern design methods Yang Lijie 1, Meng Xiangyun2,Wang Guimei1,Niu Qingna1 1 Hebei University of Engineering, Handan, Hebei, 056038, China 2 China Tele Handan Company, Handan, Hebei, 056038, China Abstract— As a modern security design, Inherent Safety means that equipment and facilities is able to contain the inherent fundamental features to prevent accidents. Mine hoist is the most important equipment in the coal production. How to achieve safe, reliable, efficient production has been the focus study at home and abroad. Inherent safety is reflected in hoist design, primarily through the design measures to improve the operation of hoist safety and reliability. In this paper, Inherent Safety theory is applied in the design of mine hoist, to proposed the design method by using the software of PRO/E?PLC, Labview etc.. KeywordsMine hoist。 Labview I. INTRODUCTION In coal production, mine hoist is the equipment to carry coal, gangue, materials, workers and equipments along the rockshaft, the only way linked underground and aboveground, known as mine throat. Mine hoist is a largescale reciprocating machinery which has the feature of own big inertia, load changes, r
