S^2 BHCA Multiple AUVs cooperation oriented control architecture

Oceanographic survey, or other similar applications should be the applications of multiple AUVs. In this paper, the skill ＆ simulation based hybrid control architecture （S^2BHCA） as the controller＇s design reference was proposed. It is a multi-robot cooperation oriented intelligent control architecture based on hybrid ideas. The S^2BHCA attempts to incorporate the virtues of the reactive controller and of the deliberative controller by introducing the concept of the ＂skill＂. The additional online task simulation ability for cooperation is supported, too. As an application, a multiple AUV control system was developed with three ＂skills＂ for the MCM mission including two different cooperative tasks. The simulation and the sea trials show that simple task expression, fast reaction and better cooperation support can be achieved by realizing the AUV controller based on the S^2BHCA.     

数字选呼技术及其应用

数字选呼(DSC)技术的发展 1912年,豪华客轮泰坦尼克号发生了海难事故.虽然,当时很多船舶已经安装了无线电收发报机和配置了专业报务员,但是在泰轮附近仅几十海里的另一艘货轮还不知道,由于救助不及时,终于酿成1500多人丧生的巨大悲剧.人们从此认识到船舶遇险报警通信必须统一、规范的重要性.     

液化石油气船

液化石油气（LPG）船大致可以分为四种不同类型。船型最小的是从事沿海运输的全加压式LPG船，舱容一般为3000-7000立方米，最大可达11000立方米。通常运输丁烷和丙烷，有时也运输乙烯基氯化物单体，货物可被压缩至18巴。这种船不能提高或降低货物温度，一般在气候较为温暖的地中海地区和印度沿海航行。
