This paper presents a design method of an off-line portable scanner, which can be used without computer. We discuss the system based on a synchronous Digital Signal Processor with multicenter, which is used to gather data with high speed. TIs TMS320VC5402 is a sixteen-bit fix processor, and we make it the core of our control system. Because it can not only handle data with high speed but also manipulate the data by abundant arithmetic/logic operations and determine the results of processing which can be output quickly as images.

The paper, concerning the characteristic of engineering and geology, studied the creation of the Xiaolangdi multipurpose project safety-monitoring system. A zoned monitoring system under the control of unique baseline has been proposed. Manu possible monitoring methods, especially, the accuracy of collimation axis、 intersection、 olar coordinate, have been studied in detail to provide the theory foundation of the application of intelligent otal-station instrument automatic monitoring system on Xiaolangdi project.The application of intelligent otal-station instrument, TCA2003, and digital water level,DiNil2, on the dam safety monitoring as well as data automatic recording have been researched extensively. All this research provide the valuable experience to in-situ data collection, automatic transferring, data analysis and treatment and management.
