Research On Survey & Design Of One-shot-Job System Based On PDA

With the developing of computer technology, information technology, network technology, and engineering technology, the " Survey & Design of One-shot-Job " is a period of new ideas in computer application development,is a necessity in survey and design of modern technology development. Realizes the survey and design integration is a difficult problem in scientific research which is also the road engineering construction faces at the present stage. in recent years, many scholars domestic and foreign conducted lots of research in this aspect, also made some achievements.In the current domestic survey and design, the field process separate completely, the tool and the method is quite backward in traditional field operation surveys ,moreover automated, intellectualized, the network, the solid current events and the visualization degree is quite low , but data electron documents is the essential condition in the field operation of surveys and design integration. is also a weak link at the present stage integration development . As a result of PDA (Personal Digital Assistant) has the volume to be exquisite , the weight light, portable, the power loss to be small conveniently ,cheap, etc., and has the general interior of the basic functions of microcomputers, and its convenient, practical embedded operating system and powerful development tools, makes the PDA on the development of professional applications become possible.Therefore, this article discusses the integration of survey and design principles in detail and its connotation with more comprehensive, including its main content, characteristic and basic requirements. According to the Survey and design for the current domestic status, proposed the survey and design operation integration system based on PDA. and has carried on the system design , introduced the working principle, design objectives and principles, and its main modules. This system with a broad range of electronic measuring instruments through the serial real-time communication, real-time graphics display, enlarge, shrink, shift, etc., as well as the route preliminary design, transfer (changes) line features such as; Finally thesis introduction of its five sub-systems of "Design model system "," Total Station System "," Level System "," RTK-GPS system "," General Survey System ".
