Water Conservancy and hydropower engineering geology and engineering geology for all these different sectors involved in the most qualified prestige Supreme hardest professional problems of the most complex tasks, which are well known beyond doubt. Computer applications in hydraulic engineering with broad development prospects, whether numerical calculation, database, application, or expert systems, network systems, are significant places; in particular engineering geological mapping (mainly refers to three dimensional problem), can be said that all professional computer graphics technology in the most complex and most difficult, is a worldwide problem in computer graphics, need our computer staff to explore geological studies.
Basically the starting point of the computer applications in hydraulic engineering and other professional sync, initial development was dramatic, after more than 10 years of hard work, along with the theme of reform and opening up, and spent from the start to the initial stages of development, entered a period of confusing stalemate, finally opened a grade toward polarization. More than 10 years of development, can be summed up as the early stage, development stage, stalemate and widen the difference in four phases.
Mid 80, PC-1500 pocket computer makes the most basic geological exploration team had the privilege of becoming owner of the computer. Compact machine for small calculation of engineering geology and hydrogeology, analysis of physical and mechanical test data consolidation, some small, simple graph drawing and so on. Many pocket computer of use their experience and achievements by dedicating, each kind of specialized technical publications posted on a large number of solutions to practical problems of the source program, spontaneously formed a free software library. Units and individuals of the exchanges is more casual and free application, to raise the level of application computer in the system as a whole has played an active role. Can say, Pocket Computer hot water conservancy hydroelectric system in the mid 80 ‘s, train talent for computer applications in the system, training team.
With the development of computer hardware and software technology, influx of PC series microcomputer market in China, domestic information technology also entered the practical stage of computer processing of Chinese characters, Chinese computer have a landmark breakthrough, water conservancy and hydropower engineering geology has entered a stage of development of good computer application. Systems leadership emphasis within some units have formed ‘ computer laboratory of engineering geology or computer group, equipped with a certain number of desktop computer, instead of some professional work in the computer application in engineering geology, have a professional team of computer applications in hydraulic engineering. This during, engineering geological professional computer application software has has is large development, draws drilling column shaped figure, and geological profile figure, and equivalent line figure, and section acting statistics figure, geological figure pieces may also reached computer out figure of practical level; database of application aspects, has has some preliminary practice and application planning; in engineering geological numerical calculation aspects, will year in Pocket machine Shang application more mature of some engineering geological calculation program moved to has microcomputer Shang, and continues to development has some new of calculation program. Together, these results reflect the geological computers gradually entered the practical stage.
Windows systems mature, platform, database, platform, and so on various programming tools, drawing, feature increasingly powerful. Computer application in water conservancy and hydropower engineering geology is naturally has a new development, mainly in the bored cylindrical mapping made some version updates, or some new progress in combination with the database, can use the profile database and data files in the AutoCAD environment to handle complex terrain, fault, non-borehole geological section of the control issues, reached the level of application. In its discussion on three-dimension model to achieve some progress on my computer, but from the practical levels there are quite a distance. Application level as a whole, basically no more major breakthroughs can propagate, here called “stalemate” or “stabilized” phase, of course, not necessarily very well. Society does not want unrest, political emphasis is stable, and science and technology in a stable state is equal to stagnation, and that is not what we want.
Development of computer application in water conservancy and hydropower engineering geological system imbalance, after starting, development, and stalemate phase quickly widen the difference will be the inevitable result. Mainly in the high level of units have established the Intranet survey system, can spread and geologic prospecting team of remote network communication, exchange of information engineering and management, computer plotting rate of more than 80, geological, geological analysis and arrangement of the information for the preparation of the report, and more are computerization has been reached.
Engineering geological professional is engineering capital of secondary tie sexual professional, in workers DAB, and mineral, and oil, and traffic, and coal, and power, industry sector are has engineering geological professional, given water hydropower engineering construction of particularity and complexity, makes water hydropower engineering geological is all these different industry of engineering geological professional in the involved surface most wide prestige Supreme problem most complex task most difficult of professional, this is known undoubtedly of. Computer applications in hydraulic engineering with broad development prospects, whether numerical calculation, database, application, or expert systems, network systems, are significant places; in particular engineering geological mapping (mainly refers to three dimensional problem), can be said that all professional computer graphics technology in the most complex and most difficult, is a worldwide problem in computer graphics, need our computer staff to explore geological studies.
Current situation analysis of causes of naturally has a deeper connotation, complexity of the limitations of the stage of social development, economic reform, institution of enterprise in the process of transition to non-adaptability and immediate interests and long-term development of contradiction, the old system of management and coordination of new operation mechanism of SB, it seems more and more complex, more analysis of the more confusing helpless. When we are good at the time to simplify the complex issues, the problem is obvious. Why some units in the same environment to walk in the forefront of the times, as long as the investigation of serious, is a common-sense conclusions can be drawn: talent.
A unit led to the development of science and technology a blind eye does not support this work, lack of leadership! No development plan, wisdom, talent shortages; development plan was bad, cannot be effective implementation of the Organization, management talent shortage; software and hardware system is dysfunctional, unable to play a benefit, or lack of professional talents of combining with computer; all in all, words: talent shortage. The nature of competition is the competition of talents, the talent shortage, or no real talent, or with a bad talent of enterprises will be eliminated by the market economy!
Currently most fashionable words: knowledge economy. Knowledge economy is the basis of the information technology, human society entered the information age, however, we also supplement lessons of the industrial age. Opportunities and challenges, industry repeatedly exclaimed, we missed the industrial civilization, must not and just miss the opportunity of information civilization, so golden opportunities, once lost, certainly is a castle in the knowledge economy.
We put aside all of the above analysis system and the real reasons, from the industry point of view of management and technology, is still two major problems, one is hardware, the second is software, their combined and more. The reconnaissance units to this attitude of the two major categories of issues widely, hardware, software, and all extremes is generally is heavy light light software, hardware configuration to play benefit application development light, heavy, light or heavy application development, popularization and improvement cannot be both, production and research cannot be simultaneously, and so on.
Software problem some more. For many years, dispersion, low levels of standardization of specialized application software, silo, very little communication and Exchange. Water Conservancy and hydropower investigation system software not conducted large-scale investment and development, but no formal developer or software organization to study exactly what we should develop software, what grades, on what criteria, certainly do not have decent software product in the commercial sense. In terms of management, planning and design of some programmes difficult to implement, input is not enough, weaknesses in the management or administrative difficulties.
In recent years, our exploration of another road is the road to free software. According to the reality of this system, our initiative the general geological development of computer enthusiasts themselves cannot form a software contributions out of a wide range of goods exchanged, received positive response. We will continue to advocate that this communication, as far as possible the creation of conditions for programming work to be the industry professional recognition, and thus be recognized by the community. Since 2000, we in RS and GPS technology, there is a substantial breakthrough, filled the blank in the surveying and mapping technology in this regard. Practices for aerial Photogrammetry aircraft taking aerial photos, Vexcel3000 and U1traScan5000 high precision scanner on pose stereopair aerial photographs and Centre (main) for digital scanning, generate a TIFF format image files. Using Shandong province water design homes introduced of Wuhan suitable General company development development of VirtuoZO312 full digital photography measurement system on image data and GPS outside industry like controlled information for air triangle measurement, and estimation empty three encryption precision, and full field broken Department point collection, and digital elevation model generated and edit, and digital are photography like generated, and are photography like measuring figure and digital line of figure edit and generated line designated figure, then for field supplement adjustable, last edit generated eventually of line designated figure, and conversion into Auto2CAD of DWG format of graphics file. Proven, RS, and compared with traditional ways of mapping GPS technology, not only greatly improves the accuracy and quality of the graphics, also increased productivity, reduce labor intensity and received considerable economic benefits.
Using GIS powerful integration of geographical data, store functionality for GPS, RS access to hydraulic engineering and product warehousing, systematic management for surveying and mapping results. For the further implementation of GIS features such as query, analysis has provided a good foundation. The development of management systems is to United States doing basic ESRI company developed the ARC/INFO software platform, at MicrosoftVisualBasic6 or MicrosoftVisualC++ development platform to support platforms to implement its functionality.
Terrain data (collected data such as GPS and total station instrument) entered into the system, after data is filtered into three dimensional vector data, further generating three-dimension terrain model DTM. Using interpolation methods, you can generate a higher precision of the DTM. DTM in the texture, lighting, and other rendering operations, that is, build lifelike digital terrain model of the whole survey area, adjust for road planning and design of water diversion project and provides a very important reference value.
Collaboration network in the area of software development principles: based software support and development of standard software, standards, research on strong professional software that is difficult. Despite hardware frequently generational, software crazy upgrade, but more is operating system, and text processing series software, and tools software, and database platform, and drawing platform,, these platform for basic meet popular operating system and programming tools of all professional sexual application software, are has one-way compatibility, therefore, professional application of Foundation sexual and standardization software has relative long-term stability of actual significance, not like those to commercial profit for purpose of software at any time eliminated at any time upgrade. It is clear that is the significance of standards based software development and software in the long run, investment sooner.
