Abstract


AUV underwater robot deep-sea operating environment is very harsh, often face a variety of hazards. In addition to it is the integration of high-tech, its development requires a lot of manpower, material and financial resources, and involves many state secrets, and each sea experiments or operating data of great value. If AUV underwater robot accident sank due to failure, will result in huge losses and marine development and research is also a heavy blow, AUV underwater robot self-help technology has become the study of underwater robot one of the key technologies. AUV developed self-rescue beacon communications and positioning software is one of the key technologies of the self-help system, the study for the entire self-help systems research, development has laid a good foundation. In this paper, the \performance assessment techniques - underwater self-help and sampling operations, discussed in detail and from the following aspects: 1, based on wireless communication technology, combined with the actual needs of the project, miniaturization, high reliability, low power consumption, distance diffraction ability, the environmental adaptability wireless transmission equipment data transfer tasks, the completion of the beacon AUV self-help and the water surface between computers. 2, the design of a GPS data acquisition and processing system, to achieve the following functions: to test the performance of GPS devices, assisted GPS devices to understand the operating characteristics; real-time dynamic received by the GPS device and the data forwarded by wireless data transmission equipment in different formats sorting processing, and give a display; create a database, the sorting information of the processed data stored in the database, for observation, and save the results given in real time display. 3, the design of a surface computer serial communication control system, the following functions: interactive real-time communication between the surface computer beacon float; beacon float data sent information analysis, processing, classification extracted all relevant information and give the display; beacon float real-time and accurate positioning and trajectory simulation; distance between the information stored in all of the command information has been sent, the position information and the beacon of the beacon float float with the mother ship in the computer, the water , in order to check for further analysis and data processing. 4, under laboratory conditions to complete the project the selected wireless data transmission equipment (high-speed wireless data transmission the radio) performance test, also completed the above two systems hardware and software tests and experiments.
