According to the development of ocean technology and equipment, diving into the deep blue becomes one of aims for international researchers who engage in works about the ocean. Acoustic survey devices(including imaging sonar, positioning sonar, anticollision sonar and Doppler Velocity Log(DVL) etc) are applied widely in deepsea vehicles(including Human Occupied Vehicle(HOV), Remotely Operated Vehicle(ROV), Autonomous Underwater Vehicle(AUV), Glider and Deep-tow etc). The purpose of acoustic survey devices is very explicit, and they are all important for deepsea vehicles when they are working underwater. Acoustic image infront of the deepsea vehicles can be given by imaging sonar, which is the most important acoustic information for deepsea vehicles. Positioning sonar can offer the comparative position between the deepsea vehicle and the mother ship. By combining with the information of the Global Position System(GPS) on the mother ship, we can calculate the absolute position of the deepsea vehicle. The information of all directions is given by anticollision sonar, which can ensure the security of deepsea vehicles. DVL can offer the velocity of the deepsea vehicle, and its information of the altitude can be set as the redundancy of the anticollision sonar which is fixed downwards. Firstly, this paper introduces the application of acoustic survey devices used on deepsea vehicles inland and abroad, including the general situation and development of applications. Secondly, a detailed introduction of acoustic survey devices used on the deepsea vehicles inland(including Jiaolong HOV, Haima ROV, 4500m AUV and OMAS(One Man Atmospheric System) etc) is focused in the paper(take the Jiaolong HOV for example). This section introduces the application of imaging sonar, bathymetric side-scan sonar, positioning sonar and anticollision sonar on the HOV, including the acoustic image and data, collected on the bottom of sea (5000-7000m). Furthermore, the advantages and deficiencies of the application of acoustic survey devices are analyzed. The status quo, problems and requirements of acoustic survey devices applied in deepsea vehicles are also summarized in this section. Finally, at the end of the paper, and with the benefit of many years experience of acoustic survey devices used in deepsea vehicles, some advice is presented about environmental conditions, platform carried and performance index of applying acoustic survey devices.
