摘要：有人可能会认为若采用高速USB,频宽就自动会增加,如此就可有效地解决大容量储存装置与计算机之间传输速率缓慢的问题。然而问题并不像看起来这么容易。因为系统架构决定了软硬件的负担以及限制,所以实际的数据有效传输率与系统架构在USB连结中是息息相关。

摘要：煤炭资源是保障我国能源安全的基石,是国民经济的重要组成部分。工业智能程度是影响现代化煤矿开采的重中之重,而智能化的核心就是对煤矿的设备运转、工业生产、信息安全等数据进行智能的监控和分析。传统的SCADA工控系统形式单一,因为设备厂商协议的限制,在一个煤矿中可能会同时存在多套系统。煤矿是一个系统繁杂、环境复杂的空间生产管理体系,想要实现煤炭无人化和少人化开采的愿景,必须要对矿区全部数据进行统一的智能分析、智能决策、智能调度。本文针对不同厂家PLC(Programmable Logic Controller)可编程逻辑控制器数据采集问题、矿区生产环境问题等,利用基于底层优化的OPC-UA协议栈,使用Redis和MySQL等数据管理工具,结合大数据技术、数据融合技术、机器学习技术,最终实现50000点I/O在2秒以内的高速、海量、智能、统一的PLC数据通信系统bridge。

摘要：The objective of a bridge design is to produce a safe bridge that is elegant and satisfies all functionality requirements, at a cost that is acceptable to the owner. A successful bridge design must be natural, simple, original, and harmonious with its surroundings. Aesthetics is not an additional consideration in the design of a bridge, but is rather an integral part of bridge design. Both the structural configuration and the aesthetics of a bridge must be considered together during the conceptual design stage. To achieve such a task, the bridge design engineer must have a good understanding of structural theory and bridge aesthetics.

摘要：The engineering community has devoted much effort to understanding the response of soil-structure systems to seismic ground motions, but little attention to the effects of an outcropping fault offset. The 1999 earthquakes of Turkey and Taiwan, offering a variety of case histories of structural damage due to faulting, have （re）fueled the interest on the subject. This paper presents a methodology for design of bridges against tectonic deformation. The problem is decoupled in two analysis steps： the first （at the local level） deals with the response of a single pier and its foundation to fault rupture propagating through the soil, and the superstructure is modeled in a simplified manner; and the second （at the global level） investigates detailed models of the superstructure subjected to the support （differential） displacements of Step 1. A parametric study investigates typical models of viaduct and overpass bridges, founded on piles or caissons. Fixed-head piled foundations are shown to be rather vulnerable to faulting-dnduced deformation. End-bearing piles in particular are unable to survive bedrock offsets exceeding 10 cm. Floating piles perform better, and if combined with hinged pile-to-cap connections, they could survive much larger offsets. Soil resilience is beneficial in reducing pile distress. Caisson foundations are almost invariably successful. Statically-indeterminate superstructures are quite vulnerable, while statically-determinate are insensitive （allowing differential displacements and rotations without suffering any distress）. For large-span cantilever-construction bridges, where a statically determinate system is hardly an option, inserting resilient seismic isolation bearings is advantageous as long as ample seating can prevent the deck from falling off the supports. An actual application of the developed method is presented for a major bridge, demonstrating the feasibility of design against tectonic deformation.
