In order to deal with the small signal of six-dimensional force sensor, a high accuracy signal processing system is designed and implemented. This system mainly consists of instrumentation amplifier circuit, anti-aliasing filter, analog sampling module, master control unit, communication module, and user software based on LABWINDOWS platform. This paper analyzes structure of the sensor and equivalent...
This paper presents an Unmanned Surface Vehicle (USV) for multi-mission applications. A small catamaran equipped with remotely operated system based on wireless local area network is developed and used as a universal platform. Outfitted with different appliances and instruments, the USV is tested for various applications including harbor surveillance, water quality sampling, hydrologic survey, maritime...
This paper presents the design of an autonomous surface vehicle (ASV) used for marine environment monitoring or hydrologic survey. A catamaran is used to improve stability against waves, and the shape of high-speed ship is exploited to reduce the resistance. The characteristics of resistance, electric motor and propeller are optimally matched, so that the battery power is saved and the endurance is...
In this paper, a wireless data transmission system used in unmanned surface vehicles is presented. To improve reliability, wireless local network based on IP is employed. Through interface protocol, multi-modal data from different observation instruments or equipments are converted into the uniform specification suitable for transmission. Different control methods of data transmission are discussed...
