Designing the three dimensional (3D) GIS software used in monitoring mineral pipeline transporting system. The software can truly show and restore the geography of project and the features of terrain .The operator can not only examine and grasp the true situation of the distribution of pipeline, but also keep watch on the secure running of the pipeline by real-time remote video in the remote control room. The practical application indicates that the pipeline can run safely, stably and efficiently with the monitoring system.

An improved progressive mesh simplification algorithm for 3D real-time level of detail rendering of shearer based on half-collapse was proposed, which has been successfully applied in the rendering of shearer and produced a good result. Virtools with its secondary development technology SDK (Software Development Kit) was applied to establishing a 3DVR(Three Dimensional Virtual Reality) digital information platform for shearer based on real-time archiving of important working parameters. By using the real-time data provided by the remote control and monitoring system for shearer, the virtual 3D model was driven to reappearance the working state and changing trend of the real one instantly. Preliminary experiments carried out in Xi’an Coal Mine Machinery Factory show that the 3DVR Digital Platform can be integrated with the remote control system for shearer well. The ability to real-time display of shearer’s working state is better than that in traditional ways, for the information is displayed in the form of data and curve in traditional control and monitoring system for shearer, which is unrealistic to the operator and unsuitable for remote control and monitoring.

A real-time mathematical model for three-dimensional tidal flow and water quality is presented in this paper. A control-volume-based difference method and a “power interpolation distribution” advocated by Patankar (1984) have been employed, and a concept of “separating the top-layer water” has been developed to solve the movable boundary problem. The model is unconditionally stable and convergent. Practical application of the model is illustrated by an example for the Pearl River Estuary.

Real time Monitoring system is an important gurantee for the water quality. SDI-12 water sensors are used to monitor the water conductivity, temperature, dissolved oxygen, Ph, turbidity and other parameters in this paper. The signal of the wastewater is collected to the ARM chip, and then it is processed by the chip. The preliminary result will be displayed on a handheld terminal in real time. The handheld terminal also integrates the function of remote data transmission, which can transmit the original water data to a central server for storage via GPRS. Central server analyse the wastewater data based on ontology. Meanwhile, the system can also control water detector via remote control, which realizes the unattended effect.

Use of µc/os-II based real-time, multi-task operating system accomplished synchronized task management and communication. An operational simulation interface for real-time monitoring of elevator was designed by hybrid programming using C and assembly languages based on data collected real time in the shared resource taken by visiting of semaphores and message boxes with shared resource in the buffer zone. In the control room, PC monitor displays elevator’s moving direction, position, condition, and any malfunction situations. It was demonstrated that the µc/os-II real-time operating system-based elevator monitoring system could not only be used under DOS window for Windows but can also be easily transferred to micro processor modules with different structures.

Stereolithography is an additive manufacturing process in which liquid photopolymer resin is cross-linked and converted to solid polymer with an ultraviolet light source. Exposure Controlled Projection Lithography (ECPL) is a stereolithographic process in which incident radiation, patterned by a dynamic mask, passes through a transparent substrate to cure a photopolymer layer that grows progressively from the substrate surface. In contrast to existing stereolithography techniques, this technique uses a gray-scale projected image, or alternatively a series of binary bit-map images, to produce a three-dimensional polymer object with the desired shape, and it can be used on either flat or curved substrates. Like most stereolithographic technologies, ECPL works in a unidirectional fashion. Calibration constants derived experimentally are fed to the software used to control the system. This unidirectional fabrication method does not, by itself, allow the system to compensate for minor variations, thereby limiting the overall accuracy of the process. We present here a simple, real-time monitoring system based on interferometry, which can be used to provide feedback control to the ECPL process, thus making it more robust and increasing system accuracy. The results obtained from this monitoring system provide a means to better visualize and understand the various phenomena occurring during the photopolymerization of transparent photopolymers.

3D visualization has become the basic requirements of many applications of GIS. However, most of the commercialization of GIS software based on two-dimensional, to describe the true three-dimensional hydraulic engineering environment. Data integration with 3D visualization technology can be obtained through various means in order to visualize three-dimensional graphics dynamically shown to provide a convenient analytical tool to handle the vast amounts of complex engineering data, has become the GIS research cutting edge of technology and research hotspot. This paper first discusses the hydraulic engineering 3D visualization modeling framework and then study the water conservancy 3D GIS model and visualize the general principles and processes. And the general approach and application effect of 3D GIS Model have been illustrated in detailed.
