[Abstract]:In addition to rich energy and mineral resources, there are also a large number of renewable energy, such as biological resources, tides and so on. China is also a large marine country, the ocean area is relatively large, with a very long coastline. Therefore, the development of marine resources in China has a very good prospect. In this paper, from the point of view of system design, we design and implement a set of offshore marine environment monitoring system which integrates various sensors and uses Beidou satellite communication as communication mode. The main contents are as follows: first, This paper introduces the background and significance of the research, the development of marine environmental monitoring system at home and abroad, and the main research contents of this paper. Second, the overall design of offshore marine environment monitoring system based on buoy. This paper introduces the whole structure of the offshore marine environment monitoring system, and then introduces the principles and advantages of the sensor technology, embedded technology, Beidou generation positioning and short message communication technology used in the monitoring system. Third, the design of offshore marine environment monitoring hardware system based on buoy. According to the overall hardware structure of the monitoring system, the selection of each subsystem and the design and implementation of the main control board are discussed, including the data acquisition subsystem, the data transmission subsystem, the main control subsystem and the power supply subsystem. Fourthly, the embedded software system design of offshore marine environment monitoring based on buoy. In this paper, the general design of the embedded software system for offshore ocean monitoring is carried out, and the construction of the embedded system software development platform is described in detail. The overall requirement of the monitoring system software is analyzed, and the flow chart of the monitoring system application software is given. At last, the subprogram of data acquisition and data sending is introduced in detail. Fifth, system test. First of all, the hardware and software of the monitoring system are debugged in the laboratory to ensure the normal operation of the system, and then the hardware and software of the monitoring system are tested in the vehicle to ensure the normal operation of the system under the simulated marine environment. Finally, further debugging is carried out in the inner lake environment, and the test results are given to verify the function and stability of the monitoring system.
